Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, specifically a pipeline construction traction resistance monitoring device. Background Technology

[0002] Pipeline traction construction is a mainstream trenchless construction technology. Its core principle is to use traction equipment to pull the pipeline along a pre-set underground trajectory from the starting shaft to the receiving shaft, achieving pipeline laying without excavating the surface. First, a pilot hole is drilled underground according to design requirements using a directional drill. Then, a reamer is used to enlarge the pilot hole to a diameter larger than the pipeline diameter. Finally, the traction equipment pulls the pipeline from the starting end along the enlarged channel to the receiving end, completing the pipeline laying. During the traction process, a resistance monitoring device is needed to monitor the pipeline. Existing monitoring devices typically only clamp the outer wall of the pipeline, which can easily cause the pipeline to detach during traction due to increased resistance, thus negating the traction and monitoring effects. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a pipeline construction traction resistance monitoring device, which solves the problem that when the monitoring device clamps the pipeline, it usually only clamps and fixes the outer wall of the pipeline, which is prone to the pipeline falling off due to the increased resistance during the traction process, thus canceling the traction and monitoring effect of the pipeline.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipeline construction traction resistance monitoring device, comprising a mounting base, an electric telescopic rod fixedly connected to one side of the mounting base, a connecting block installed at one end of the electric telescopic rod, the connecting block being slidably connected to the inner wall of the mounting base, a turntable rotatably connected to the middle position of the inner wall of the mounting base via a bearing, four connecting rods rotatably connected to one side of the turntable via pins, a movable block rotatably connected to the end of each connecting rod away from the turntable via a pin, one of the movable blocks being fixedly connected to the connecting block, the movable block being slidably connected to the mounting base, a clamping block one being fixedly connected to one side of the movable block, four linkage rods rotatably connected to the side of the turntable away from the connecting rods via pins, a slider rotatably connected to the end of each linkage rod away from the turntable via a pin, the slider being slidably connected to the mounting base, and a clamping block two being fixedly connected to one side of the slider.

[0005] As a further embodiment of this utility model: tension sensors are installed on both sides of the mounting base on the electric telescopic rod, and the two tension sensors are connected to the same connecting seat at the end away from the mounting base.

[0006] As a further embodiment of this utility model: two sliding grooves are symmetrically opened on the outer wall of the connecting seat, and several positioning columns are fixedly connected to the side of the connecting seat away from the tension sensor.

[0007] As a further embodiment of this utility model: a fixing post is provided on one side of the connecting seat, and several positioning grooves are opened inside the fixing post, the positioning grooves corresponding to the positions of the positioning post.

[0008] As a further embodiment of this utility model: four fixing blocks are fixedly connected to the outer wall of the fixing column, two limiting rods are fixedly connected between two fixing blocks, and an installation block is slidably connected through the two limiting rods. A return spring is sleeved on the surface of the limiting rod at the top of the installation block.

[0009] As a further embodiment of this utility model: a limiting block is fixedly connected to one side of the mounting block, the limiting block is corresponding to the position of the sliding groove, and four locking blocks are fixedly connected to the outer wall of the fixing column, the locking blocks being engaged with the mounting block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This pipeline construction traction resistance monitoring device, by setting up an electric telescopic rod, a connecting block, a turntable and a linkage rod, the electric telescopic rod drives the connecting block to move, which in turn drives one of the movable blocks to move. This movable block drives the turntable to rotate through the connecting rod, and the turntable drives the connecting rod and the linkage rod to move at the same time. This causes the connecting rod to move inward into the mounting base, while the linkage rod drives the slider to move outward from the mounting base. As a result, clamping block one and clamping block two simultaneously press against the inside and outside wall of the pipeline, achieving stable clamping and fixing of the pipeline and reducing the probability of the pipeline falling off during traction. 2. This pipeline construction traction resistance monitoring device, by setting a positioning column, positioning groove, return spring and limit block, pulls the installation block, the installation block squeezes the return spring and the locking block to engage, the positioning column is aligned with the positioning groove and then moved, the connecting seat drives the positioning column to insert into the positioning groove, at the same time the slide and the limit block are inserted, the locking block is released from the locking block to the installation block, so that the return spring drives the installation block to return to its original position through the elastic force, so that the installation block drives the limit block to move inside the slide. As the locking block and the installation block engage, the connecting seat and the fixed column are fixedly installed. Attached Figure Description

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: a pipeline construction traction resistance monitoring device, including a mounting base 1. Tension sensors 11 are installed on both sides of the mounting base 1 on the electric telescopic rod 2. The two tension sensors 11 are connected to the same connecting seat 12 at the ends away from the mounting base 1. By setting the tension sensors 11, the tension sensors 11 can monitor the pipeline traction process clamped by the mounting base 1, ensuring that the pipeline traction resistance can be observed in real time. Two sliding grooves 13 are symmetrically opened on the outer wall of the connecting seat 12. Several positioning posts 14 are fixedly connected to the side of the connecting seat 12 away from the tension sensor 11. By setting the sliding grooves 13, the sliding grooves 13 are inserted into the limiting block 21 to realize the fixed installation of the connecting seat 12 and the fixing post 15. A fixing post 15 is provided on one side of the connecting seat 12. Several positioning slots 16 are opened inside the fixing post 15. The positioning slots 16 correspond to the positions of the positioning post 14. By setting the positioning slots 16, the positioning slots 16 and the positioning post 14 are inserted into each other, thereby realizing the positioning and installation of the connecting seat 12 on one side of the fixing post 15. Four fixing blocks 17 are fixedly connected to the outer wall of the fixed column 15. Two limiting rods 18 are fixedly connected between two fixing blocks 17. An installation block 20 is slidably connected through the two limiting rods 18. A return spring 19 is sleeved on the surface of the limiting rod 18 at the top of the installation block 20. By setting the limiting rod 18, when the installation block 20 moves and squeezes the return spring 19, the limiting rod 18 can limit the installation block 20 and the return spring 19, making the movement of the installation block 20 and the return spring 19 more stable. A limiting block 21 is fixedly connected to one side of the mounting block 20. The limiting block 21 corresponds to the position of the slide groove 13. Four locking blocks 22 are fixedly connected to the outer wall of the fixing column 15. The locking blocks 22 are engaged with the mounting block 20. By setting the locking blocks 22, the locking blocks 22 are engaged with the mounting block 20, thereby fixing and limiting the mounting block 20, so that the mounting block 20 and the limiting blocks 21 can stably engage and fix the connecting seat 12. An electric telescopic rod 2 is fixedly connected to one side of the mounting base 1. A connecting block 3 is installed at one end of the electric telescopic rod 2. The connecting block 3 is slidably connected to the inner wall of the mounting base 1. A turntable 4 is rotatably connected to the middle of the inner wall of the mounting base 1 via a bearing. Four connecting rods 5 are rotatably connected to one side of the turntable 4 via a pin. A movable block 6 is rotatably connected to the end of the connecting rod 5 away from the turntable 4 via a pin. One of the movable blocks 6 is fixedly connected to the connecting block 3. By setting the turntable 4, the rotation of the turntable 4 can synchronously drive the connecting rods 5 and the linkage rod 8 to slide together, thereby allowing the connecting rods 5 and the linkage rod 8 to drive the clamping block 7 and the clamping block 10 to move together, so as to achieve simultaneous clamping and fixing of the inner and outer walls of the pipe. The movable block 6 is slidably connected to the mounting base 1. A clamping block 7 is fixedly connected to one side of the movable block 6. Four linkage rods 8 are rotatably connected to the side of the turntable 4 away from the connecting rod 5 via a pin. A slider 9 is rotatably connected to the end of the linkage rod 8 away from the turntable 4 via a pin. The slider 9 is slidably connected to the mounting base 1. A clamping block 10 is fixedly connected to one side of the slider 9. By setting the slider 9, the slider 9 can slide inside the mounting base 1, so that the mounting base 1 can limit the movement of the slider 9, so that the slider 9 can stably drive the clamping block 10 to abut against the inner wall of the pipe.

[0014] The working principle of this utility model is as follows: Pulling the mounting block 20 causes it to move upwards, pressing the return spring 19 and engaging with the locking block 22. This aligns the positioning post 14 and inserts it into the positioning groove 16, placing the connecting seat 12 on one side of the fixing post 15. Simultaneously, the limiting block 21 is inserted into the sliding groove 13. Pressing the locking block 22 releases the limiting effect on the mounting block 20. The return spring 19, through its elastic force, moves the mounting block 20, causing it to slide the limiting block 21 within the sliding groove 13. Simultaneously, the locking block 22 engages with the mounting block 20, thus fixing the connecting seat 12 to one side of the fixing post 15. Place the pipe against the surface of the mounting base 1, activate the electric telescopic rod 2, which drives the connecting block 3 to move. The connecting block 3 can then drive the turntable 4 to rotate via the movable block 6 and the connecting rod 5. This allows the turntable 4 to simultaneously drive the connecting rod 5 and the linkage rod 8 to rotate together. As the connecting rod 5 pushes the clamping block 7 to move via the movable block 6, the linkage rod 8 drives the clamping block 10 to move via the slider 9. This allows the clamping block 10 and the clamping block 7 to simultaneously press against the surface of the pipe, fixing the pipe to one side of the mounting base 1. This facilitates the tension sensor 11 to monitor the resistance during the traction process of the pipe.
