Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically to an auxiliary device for cable laying in power pipeline construction. Background Technology

[0002] In cable laying during power pipeline construction, existing traction machines exhibit poor power output stability. During prolonged operation or under significant load variations, they are prone to speed fluctuations and inconsistent traction force, affecting the uniformity and stability of cable laying, potentially damaging cables and increasing equipment wear. Furthermore, the traction force adjustment precision is limited, making it difficult to accurately adjust according to the material of different cables, pipe diameters, and specific requirements of the laying environment. This often results in problems such as excessive traction force breaking cables or insufficient traction force failing to effectively pull the cables.

[0003] Therefore, those skilled in the art have provided an auxiliary device for cable laying in power pipeline construction to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for cable laying in power pipeline construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0010] As a further embodiment of this utility model: a right upper connecting block is fixedly connected to the upper end of the side surface of the right vertical plate near the left vertical plate, and a right lower connecting block is fixedly connected to the lower end of the side surface of the right vertical plate near the left vertical plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Improve power output stability and traction adjustment accuracy: By using two rotating rollers to clamp the traction rope, the clamping force of the traction rope is dynamically adjusted through the clamping device to ensure that the traction machine can output power stably under different loads and working conditions. When the load increases, the clamping force is increased to ensure that the traction rope and the traction machine do not slip, so that the power can be stably transmitted to the cable and avoid power output fluctuations caused by slippage. Conversely, when the load decreases, the clamping force is appropriately reduced to reduce unnecessary energy loss and maintain the stability of power output.

[0016] 2. Reduced traction rope wear: Because the clamping force of the rollers on the traction rope can be precisely controlled, excessive wear on the surface of the traction rope caused by excessive clamping force is avoided, thus extending the service life of the traction rope and reducing the cost and frequency of traction rope replacement.

[0017] 3. Easy to maintain and repair: The structural design of each component is relatively independent, and the installation and disassembly of components such as pressure sensors and bearing seats are relatively convenient. Attached Figure Description

A right upper connecting block 13 is fixedly connected. A right lower connecting block 21 is fixedly connected to the lower end of the side surface of the right vertical plate 9 near the left vertical plate 8. The right upper connecting block 13 and the right lower connecting block 21 are respectively provided with a right upper groove 15 and a right lower groove 23 at the end near the left vertical plate 8. The right upper pressure sensor 17 and the right lower pressure sensor 25 are respectively fixedly installed at the bottom of the right upper groove 15 and the right lower groove 23. The right upper bearing seat 19 and the right lower bearing seat 27 are respectively slidably installed at the groove opening of the right upper groove 15 and the right lower groove 23. The upper and lower ends of the right rotating roller 11 are fixedly connected to the inner rings of the right upper bearing seat 19 and the right lower bearing seat 27 through rotating shafts. The mounting plate 1 is fixedly installed on the frame of the traction machine by bolts. The left upper pressure sensor 16, the right upper pressure sensor 17, the left lower pressure sensor 24, and the right lower pressure sensor 25 are all electrically connected to an external controller.

[0028] Working Principle: First, the mounting plate 1 is securely fixed to the frame of the traction machine with bolts to ensure the stability of the entire auxiliary equipment. Then, the traction rope is placed between the left rotating roller 10 and the right rotating roller 11. The electro-hydraulic levers 6 and 7 are activated, causing their output ends to move relative to each other, pushing the left vertical plate 8 and the right vertical plate 9 closer together. This, in turn, causes the left rotating roller 10 and the right rotating roller 11 to clamp the traction rope. During the clamping process, the upper left pressure sensor 16, the upper right pressure sensor 17, the lower left pressure sensor 24, and the lower right pressure sensor 25 monitor the clamping force of the rollers on the traction rope in real time and convert the pressure data into electrical signals, which are then transmitted to the external controller. The external controller analyzes and processes this data, comparing the actual clamping force with the preset target clamping force. If the actual clamping force is less than the target value, the controller will control the electro-hydraulic levers 6 and 7 to continue extending, increasing the clamping force of the rollers on the traction rope. If the actual clamping force of the guide rope exceeds the target value, the controller will control the electro-hydraulic rods 6 and 7 to retract appropriately, reducing the clamping force and thus achieving precise adjustment of the clamping force. When the clamping force of the roller on the traction rope reaches the appropriate value, the traction machine starts and pulls the cable through the traction rope to lay it in the power pipeline. During the laying process, the pressure sensor continuously monitors the change in clamping force. At the same time, combined with the tension sensor and speed sensor on the traction machine, the working status information of the traction machine is obtained. The external controller adopts intelligent control strategies such as PID control algorithm or fuzzy control algorithm based on the monitoring results. According to the information fed back by the sensor and the preset traction force target value, the drive system of the clamping device is automatically adjusted so that the clamping force can quickly and accurately reach the set value and remain stable. The extension and retraction of the electro-hydraulic rod is adjusted in real time to ensure that the power output of the traction machine is stable and the traction force is precisely adjusted throughout the laying process.
