Talking about the process of lifting column installation method

The choice of installing the lifting column is generally to prevent the vehicle from forcibly passing through restrictions on passing vehicles, so that pedestrians and electric vehicles can pass well, and the traffic order and the safety of major facilities and places are guaranteed. For the installation of the lifting column, it is generally considered that the center point of the lifting column and the lifting column is the starting point, and the intermediate interval is controlled below 1.4M. If there are special requirements, the installation spacing of the lifting column can be appropriately reduced.

The following is the installation method of Tongdazhi's lifting column:

Step 1: Digging and slotting

Dig the foundation pit according to the product dimensions, the base pit size:

Length: Determine the size according to the scene of the site;

Width: 800-1000mm

Depth: 1400-1500mm (including 300mm water seepage layer)

Step 2: Natural water seepage

First spread the stone evenly into the excavated foundation pit (thickness 250mm) and then lay a layer of fine yellow sand (thickness 250mm) above the stone.

03Step 3: Place the lifting column

1. Separate the inner and outer cylinders of the column as shown above.

Horizontal line of installation equipment: along the center of the vertical ditch of the foundation ditch, draw a straight line with the rope at both ends of the ground. The horizontal groove width direction is drawn according to the center of each equipment installation position and the ground level to form equipment installation. Cross positioning line. It is required that the ends of each line be fixed with steel nails and not displaced.

Backfill or clean the fine sand at the bottom of the foundation tank according to the height of the pre-embedded barrel of each equipment, so that the height of the pre-embedded barrel of each equipment above the basic tank is the same.

Step 4: Laying the threading pipe and threading

1. Insert one end of a PVC 5.0cm elbow into the pre-embedded barrel and hold it with waterproof tape. Insert the depth to about 30MM, and the other end to the equipment control box, one for each pre-embedded barrel. When laying the threading pipe, it is required to ensure smooth threading and cable replacement when there is a fault.

Threading and grounding: Each barrier device is individually threaded (the RVV7*2.5 cable is used for the roadblock and the RVV5*2.5 cable is not included). A separate threading pipe is required for each cable. It is required that no cable is inserted into the pre-embedded bucket, and it is taken out from the pre-buried bucket to the top of the pre-embedded bucket, and is 1.3 meters above the top of the pre-embedded bucket. 0.7 m, the grounding wire uses a BVR2.4 alone.

Step 5: Welded pre-buried barrel reinforced steel bar welding process: After the cable line is laid, it is necessary to re-confirm the intersection line between the pre-embedded barrel and the foundation ditch, and start welding after height, vertical and concentric level.

1. The first layer; the well-shaped fixed frame is welded with the steel bar as the center, and the welding is firmly welded in three layers. The two ends of the steel bar are required to be inserted into the four walls of the foundation ditch. The first layer is 30 cm away from the bottom of the pre-embedded barrel. After the welding is completed, the pre-buried barrel is corrected again, and it is determined that the second layer is welded after being prepared, otherwise the pre-buried barrel cannot be corrected after the second layer is welded.

2. The second layer is welded in the middle of the pre-embedded barrel in the same way as the first time, and the third time is 20 cm from the upper part of the pre-embedded barrel.

Step 6: Wiring part of the process

1. Road pile equipment power unit reserved line: The road pile power unit motor is a three-core cable line which is blue line in turn. The brown line, the flower line and the solenoid valve are two black lines, and there is a two-core spiral light line with warning lights. There are seven lines, five lines without warning lights, and the pre-embedded barrel fixed steel bars are welded. wiring.

2. Wiring process: Put the power unit hydraulic integrated machine on the ground side of the foundation groove of the pre-buried barrel, and connect the seven-core cable drawn from above the pre-embedded barrel to the motor line, battery valve line and warning light of the power unit. on-line. Accurately remember the line number or color of the seven-core cable, and the color of the wire corresponding to the motor, battery valve and warning light on the device, so as to avoid the wrong connection of the control box.

3. Equipment wiring description: The 3 lines of the motor line on the road pile are on the blue motor, the brown motor, and the scribing motor are common. The terminals corresponding to the control box cannot be connected. Battery valve 2 separate black wires, connected to control

Box battery valve, battery valve common corresponding terminal, regardless of positive and negative. The two wires of the warning light wire are connected to the common terminal of the control box warning light and warning light, regardless of the positive and negative poles.

4. Wiring standard: After the wire is connected, it is required to be soldered with solder. First, wrap it with plastic tape, then wrap the two layers with high-pressure waterproof tape, then wrap it with plastic tape, and finally wrap it with electric asphalt tape. After the line is connected, the wiring of the terminal is trimmed and fixed under the power unit to prevent the external force from breaking the wiring. After finishing the work, first connect the two wires of the power unit to the warning light, and measure the other end of the cable with a multimeter. The three wire motors are open, and the two wire battery valves are open. The two lamp wires are open, and the motor, battery valve and wire cannot be connected. After confirming, put the power unit into the pre-embedded bucket, and fix the hydraulic bolts in the clockwise direction. Button, you can use wooden sticks, etc., the remaining cable, the standard ground to the bottom of the hydraulic power unit, to avoid whether the lifting column drops against the wire, each pile is connected to the corresponding terminal row in the control box, can refer to control Box wiring diagram

Step 7: Backfill

Make sure that the pre-buried barrel steel is welded firmly, connect the grounding wire, first backfill the residual soil by 20 cm to prevent concrete from seeping into the underground seepage layer. When pouring concrete, the pouring height is reserved for 10 cm below the road surface. Restore original pavement and other pavement design

Step 8: Debugging

According to the disassembly sequence and steps of the road pile equipment, re-install the equipment in sequence, and tighten the fixing screws of each link. After the equipment is assembled, adjust the three slide rails to ensure that the gap between the column and the floor cover is even and the lift is determined. Smooth, no carton situation.
