Description

Technical Field

[0001] The present application relates to the technical field of tunnel pipes, and specifically to a hoisting and connecting structure for precast segments. Background Art

[0002] At present, tunnel pipes are connected in a lap joint manner. The characteristic is that the length of the connection part is short, generally times the outer diameter of the tunnel pipe. When connecting, it is necessary to align the lap joint parts at both ends of the tunnel pipe, and then connect the two tunnel pipes together through bolts and flanges.

[0003] The existing connection parts of tunnel pipes have low strength and poor sealing performance, and it is difficult to adjust the position of the tunnel pipes after placement. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present application provides a hoisting and connecting structure for precast segments, which has the advantages of improving the strength of the connection between adjacent tunnel pipes, enhancing the sealing performance of the tunnel pipes, facilitating operators to move the tunnel pipes and turn the tunnel pipes according to needs, etc., and solves the problems of low strength of the existing connection parts of tunnel pipes, poor sealing performance, and difficulty in adjusting the position of the tunnel pipes after placement.

[0005] To achieve the above object, the present application provides the following technical solution: A hoisting and connecting structure for precast segments, including a tunnel pipe. A rubber strip is provided on the outer circumferential surface of the tunnel pipe, and a steel ring is provided on the outer circumferential surface of the rubber strip. Two tunnel pipe grooves are opened on the outer circumferential surface of the tunnel pipe. A hoisting member is provided above the tunnel pipe. A motor is fixedly connected to the right side surface of the hoisting member. A lead screw is drivingly connected to the left side of the motor. The outer circumferential surface of the lead screw is rotationally connected to the inside of the hoisting member. Two moving blocks are threadedly connected to the outer circumferential surface of the lead screw. A steel rope is fixedly connected to the bottom surface of each moving block, and a plug-in member is fixedly connected to the bottom surface of the steel rope.

[0006] Through the above solution, due to the low strength and poor sealing performance of the existing connection parts of tunnel pipes, and the difficulty in adjusting the position of the tunnel pipes after placement, by providing a rubber strip at the connection of the tunnel pipes, the sealing performance of the connection between adjacent tunnel pipes is enhanced. By providing a steel ring on the outer wall of the rubber strip for fixing the rubber strip, the strength of the connection between adjacent tunnel pipes is improved. By providing tunnel pipe grooves, a hoisting member and a plug-in member, it is convenient for operators to move the tunnel pipes and turn the tunnel pipes according to needs.

[0007] Further, two docking protrusions are fixedly connected to the inner wall of the rubber strip. Two grooves are opened on the outer circumferential surface of the tunnel pipe, and the docking protrusions are respectively embedded inside the grooves.

[0008] Through the above solution, the docking protrusions can be embedded inside the grooves, improving the sealing effect of the rubber strip and enhancing the sealing performance of the connection between adjacent tunnel pipes.

[0009] Furthermore, the rubber strip is in interference fit with the groove through the docking protrusion, and the steel ring is in interference fit with the rubber strip.

[0010] With the above solution, the connection between the two tunnel pipes is fastened and sealed by the rubber strip, and the rubber strip is fixed by the steel ring, improving the sealing effect of the connection part between two adjacent tunnel pipes and also enhancing the strength of the connection part between two adjacent tunnel pipes.

[0011] Furthermore, the positions of the plug connectors correspond to the positions of the tunnel pipe grooves respectively, and the structures of the plug connectors are adapted to the structures of the tunnel pipe grooves.

[0012] With the above solution, the plug connectors can be inserted into the tunnel pipe grooves on both sides of the tunnel pipe, and the tunnel pipe can be flipped and moved by the lifting member.

[0013] Furthermore, two threaded structures are provided on the outer circumferential surface of the lead screw, and the thread track directions of the two threaded structures on the outer circumferential surface of the lead screw are opposite.

[0014] With the above solution, the two moving blocks can be made to move in opposite directions, and then the two plug connectors are driven to move and retract by the steel rope, and the positions of the two plug connectors are adjusted according to the size of the tunnel pipe, thus facilitating the lifting operation.

[0015] Furthermore, a lifting plate is fixedly connected to the upper surface of the lifting member, and a lifting groove is formed inside the lifting plate.

[0016] With the above solution, the hook of the external lifting device can be connected to the lifting member through the lifting groove, and then the lifting operation is carried out through the lifting member.

[0017] Furthermore, two sliding plates are fixedly connected to the outer surface of each moving block, two sliding grooves are formed inside the lifting member, and the outer surfaces of the sliding plates are respectively slidably connected to the lifting member through the sliding grooves.

[0018] With the above solution, the moving block is restricted to prevent it from rotating with the lead screw, so that the moving block always moves along the sliding groove with the sliding plate as the track. At the same time, the sliding plate can also support and reinforce the moving block, increasing the stability of the movement of the moving block.

[0019] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the lead screw, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the lifting member.

[0020] With the above solution, the lead screw is reinforced by the limiting ring to prevent the lead screw from sliding and shifting easily, increasing the stability of the movement of the lead screw.

[0021] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0022] The hoisting and connecting structure of the precast segment enhances the sealing performance at the joint of adjacent tunnel segments by setting rubber strips at the tunnel joint, improves the strength at the joint of adjacent tunnel segments by setting steel rings on the outer wall of the rubber strips, and facilitates the operators to move and flip the tunnel segments according to requirements by setting tunnel segment grooves, lifting parts and plug connectors, thus solving the problems of low strength and poor sealing performance at the connection part of existing tunnel segments and difficulty in adjusting the position of tunnel segments after placement.
