Description

Technical Field

[0001] This utility model relates to the field of communication construction technology, and in particular to a pipeline auxiliary docking device for communication pipeline construction. Background Technology

[0002] Communication ducts are underground protective spaces built for laying communication cables. The ducts form a robust protective layer to prevent damage to the cables from the external environment and to ensure the reliability and stability of the communication duct system when carrying massive data flows.

[0003] When laying pipelines, using auxiliary pipeline docking devices to help connect the pipeline ends can ensure the accuracy and safety of the pipeline docking, improve construction efficiency and project quality. The locking mechanism of existing auxiliary pipeline docking devices relies on threaded connections. Since communication pipeline construction is mostly carried out underground, the auxiliary docking devices are in a muddy and watery environment for a long time, and the threads are prone to rust. During locking, the threads are prone to stripping. If subjected to external vibration, the locking mechanism may loosen, which can easily cause misalignment of the pipeline docking. When the locking mechanism uses elastic buckles, it relies on its own elasticity to lock, and long-term disassembly and assembly can easily cause stress fatigue, resulting in a decrease in locking force and a risk of accidental disengagement, which affects construction efficiency.

[0004] Therefore, given that the locking mechanisms of existing auxiliary pipe docking devices used in communication pipeline construction mostly employ threaded connections or elastic clips, which are prone to failure after long-term disassembly and assembly, a new auxiliary pipe docking device for communication pipeline construction can be designed. This device utilizes hydraulically driven locking, facilitating disassembly and assembly, ensuring that the pipe does not easily loosen during the pipe docking process, and improving the reliability and stability of the construction. Utility Model Content

[0005] To overcome the problem that most communication pipeline auxiliary docking devices use threaded connections for locking mechanisms, which are prone to rust or stripping and loosening due to vibration during pipeline docking, elastic clips are used. However, these clips are prone to fatigue due to frequent disassembly and assembly, posing a risk of accidental detachment and causing misalignment of the pipeline docking.

[0006] The technical solution of this utility model is as follows: a pipe auxiliary docking device for communication pipeline construction, including a bracket, the bracket being ring-shaped, and further including a clamping mechanism composed of a first clamping member and a second clamping member and a hydraulic locking mechanism. The bracket is formed into three detachable parts through the clamping mechanism. The second clamping member is fixedly connected to the upper inner wall of the bracket, and the first clamping member is symmetrically fixedly connected to the lower inner wall of the bracket. The inner wall of the clamping mechanism is provided with protrusions, and the hydraulic locking mechanism is symmetrically arranged on the outside of the bracket. The first clamping member and the second clamping member are clamped to the pipe body through the hydraulic locking mechanism.

[0007] Preferably, the hydraulic locking mechanism has a bracket fixedly connected to one end and a pusher rotatably connected to the other end, with the other end of the pusher fixedly connected to the bracket.

[0008] Preferably, a linkage mechanism is rotatably connected to one side of the pusher, and a fixing member is slidably connected to the other end of the linkage mechanism. The fixing member is fixedly connected to the outside of the bracket.

[0009] Preferably, the clamping mechanism is configured as two sets, one set of which is fixedly connected to a positioning rod on its periphery, and the other set of which has a limit groove on its periphery, with the positioning rod and the limit groove being plugged and plugged into each other.

[0010] Preferably, a positioning component is fixed to the outside of the bracket, a sliding rod is fixedly connected to one end of the positioning component, and a movable component is slidably connected to the other end of the sliding rod. The movable component is fixed to the outside of the bracket.

[0011] Preferably, an auxiliary locking mechanism is installed at the bottom of the bracket to help lock the first clamping member.

[0012] Preferably, a sealing ring surrounds the outside of the clamping mechanism.

[0013] The beneficial effects of this utility model are:

[0014] Compared to existing pipe auxiliary docking devices used in communication pipeline construction, the hydraulically driven locking and clamping mechanism improves the stability and reliability of the locking mechanism in extreme environments. The hydraulic locking mechanism fixes the first clamping component and the second clamping component, making it less prone to loosening when vibration occurs during the pipe body docking process. Furthermore, the hydraulic drive facilitates disassembly, improving construction efficiency. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a pipe auxiliary docking device for communication pipeline construction, including a bracket 1, which is circular in shape, and a clamping mechanism composed of a first clamping member 2 and a second clamping member 201 and a hydraulic locking mechanism 302. The bracket 1 is formed into three detachable parts by the clamping mechanism. The second clamping member 201 is fixedly connected to the upper inner wall of the bracket 1, and the first clamping member 2 is symmetrically fixedly connected to the lower inner wall of the bracket 1. The inner wall of the clamping mechanism is provided with a protrusion, and the hydraulic locking mechanism 302 is symmetrically provided on the outside of the bracket 1. The first clamping member 2 and the second clamping member 201 are clamped to the pipe body 6 by the hydraulic locking mechanism 302.

[0023] The hydraulic locking mechanism 302 is driven by a hydraulic cylinder and has a built-in hydraulic control check valve. When the hydraulic cylinder needs to work, the hydraulic control check valve is opened so that the hydraulic locking mechanism 302 can control the movement of the clamping mechanism. When locking is required, the hydraulic control check valve is quickly closed to cut off the oil pressure control and fix the hydraulic cylinder in the current position.

[0024] The inner wall of the clamping mechanism is provided with protrusions to increase friction and reduce slippage of the clamping mechanism;

[0025] When clamping the pipe body 6, the clamping mechanism is disassembled into a first clamping member 2 and a second clamping member 201. The pipe body 6 is placed inside the second clamping member 201, and the hydraulic locking mechanism 302 is activated, which drives the first clamping member 2 to hug the pipe body 6 inward. The hydraulic cylinder is controlled by the hydraulic control check valve to lock the hydraulic locking mechanism 302, effectively preventing loosening when the pipe is connected and moved.

[0026] Furthermore, one end of the hydraulic locking mechanism 302 is fixedly connected to the bracket 1, and the other end is rotatably connected to the pusher 303, the other end of which is fixedly connected to the bracket 1;

[0027] The pusher 303 is rotatably connected to a linkage mechanism 3 on one side, and a fixing member 301 is slidably connected to the other end of the linkage mechanism 3. The fixing member 301 is fixedly connected to the outside of the bracket 1.

[0028] The hydraulic locking mechanism 302 is activated to drive the pushing component 303. At the same time, the linkage mechanism 3 slides around the fixing component 301, thereby pushing the first clamping component 2 to hug the pipe body 6 inward. Although the first clamping component 2 and the second clamping component 201 are separated, they are connected by the linkage mechanism 3, which can achieve rapid splicing and avoid wasting time and reducing construction efficiency by searching for other clamping components.

[0029] Furthermore, a positioning component 701 is fixed to the outside of the bracket 1. A sliding rod 7 is fixedly connected to one end of the positioning component 701, and a moving component 702 is slidably connected to the other end of the sliding rod 7. The moving component 702 is fixed to the outside of the bracket 1.

[0030] The clamping mechanism is set into two sets. One set of clamping mechanism is fixedly connected to the periphery of the positioning rod 5, and the other set of clamping mechanism is provided with a limit groove 4. The positioning rod 5 is plugged into and pulled into the limit groove 4.

[0031] When the pipe body 6 is docked, the moving part 702 is pushed to slide along the sliding rod 7 toward the positioning part 701. When the moving part 702 docks with the positioning part 701, the positioning rod 5 is inserted into the limiting groove 4 to ensure that the end of the pipe body 6 is accurately docked.

[0032] Furthermore, an auxiliary locking mechanism 8 is installed at the bottom of the bracket 1 to assist in locking the first clamping member 2.

[0033] The auxiliary locking mechanism 8 is driven by any one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The auxiliary locking mechanism 8 further locks the first clamping member 2 to prevent the clamping mechanism from loosening after the hydraulic locking mechanism 302 fails.

[0034] Furthermore, a sealing ring 9 surrounds the outside of the clamping mechanism.

[0035] Through the above steps, compared with the existing auxiliary pipe docking device for communication pipeline construction, the hydraulically driven locking and clamping mechanism improves the stability and reliability of the locking mechanism in extreme environments. The first clamping member 2 and the second clamping member 201 are fixed by the hydraulic locking mechanism 302. When the pipe body 6 vibrates during docking, it is not easy to loosen. Moreover, the hydraulic drive facilitates disassembly and improves construction efficiency.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
