Description

Technical Field

[0001] The present application relates to the field of traction devices, and in particular to a multi-pipeline synchronous traction device. Background Art

[0002] At present, with the development of society, the urbanization process in China is getting faster and faster. Some of the overhead lines commonly seen in rural areas and suburbs have been converted to buried cables, which not only saves space but also has benefits for the beauty of the city. However, when laying cables underground, the cables cannot be buried directly. Cable wells, cable pipes, etc. must be used for cable laying. When laying cables in cable pipes, since the pipes are very long, some can reach hundreds of meters, and the cables themselves are soft, it is difficult to pass through cable pipes of dozens or hundreds of meters. Therefore, it is necessary to use a threader to pass through the pipe and then pull a tension rope or wire rope, and use the wire rope to pull the cable through the cable pipe.

[0003] Mechanical and electrical installation accounts for a large proportion in building construction and is becoming increasingly important. However, the transportation of pipeline systems is currently mainly done by manpower, carried out by dragging on shoulders and hands. This traditional dragging transportation method is not only inefficient, but also damages the pipelines. Summary of the Invention

[0004] In order to improve the transportation efficiency of the pipeline system and reduce the workload of workers, the present application provides a multi-pipeline synchronous traction device.

[0005] This application provides a multi-pipeline synchronous traction device, which adopts the following technical solutions:

[0006] A multi-pipeline synchronous traction device includes a telescopic device supported and fixed on the inner wall of the pipeline and a control device that drives the telescopic device to support the pipeline. One end of the control device is connected to the telescopic device, and the end of the control device away from the telescopic device is provided with a fixing device. The control device can be snap-fitted to the fixing device. The side of the fixing device away from the control device is provided with an electrically controlled driving device, and the driving device can pull the fixing device to move.

[0007] By adopting the above technical solution, the present application installs the control device on the fixing device, and uses the control device to enable the telescopic device to be supported on the inner wall of the pipeline for fixation, and finally uses an electrically controlled driving device to pull the fixing device, thereby achieving traction of the pipeline. The pipeline is fixed in the form of electric control and mechanical means, avoiding excessive manpower, reducing the workload of the staff, and improving the transportation efficiency of the pipeline system.

[0008] Optionally, the fixing device can be snap-fitted with multiple sets of control devices and telescopic devices.

[0009] By adopting the above technical solution, multiple groups of control devices and telescopic devices are snap-fitted to the fixing device, so that multiple pipelines can be towed at the same time, thereby improving the transportation efficiency of the pipelines.

[0010] Optionally, the fixing device includes an upper guard plate and a lower guard plate, the upper guard plate and the lower guard plate are rotatably connected to each other, and a plurality of mounting holes are cooperatively provided on the upper guard plate and the lower guard plate, the end of the control device can be set in the mounting hole, and a locking assembly is provided between the upper guard plate and the lower guard plate to fix the two.

[0011] By adopting the above technical solution, the upper guard plate and the lower guard plate are rotatably arranged, and the mounting holes are arranged between the upper guard plate and the lower guard plate. When fixing the control device, the upper guard plate and the lower guard plate can be opened relative to each other, and one end of the control device can be installed in the mounting hole, so that the connection between the control device and the fixing device is more secure, and the locking assembly can fix the upper guard plate and the lower guard plate.

[0013] By adopting the above technical solution, the lock assembly is simple in structure and convenient for staff to use. When one end of the control device is installed in the mounting hole, the upper guard plate and the lower guard plate are rotated and buckled together so that the fixed lock can fix the same side edges of the upper guard plate and the lower guard plate.

[0014] Optionally, the telescopic device includes a first mounting block and a second mounting block arranged coaxially, the first mounting block is sleeved on the control device, the second mounting block is fixed to one end of the control device, and the control device can drive the second mounting block toward or away from the first mounting block, and the first mounting block and the second mounting block are provided with support components that are supported on the inner wall of the pipe.

[0015] By adopting the above technical solution, when fixing the pipeline, the telescopic device can first be retracted and then extended into the interior of the pipeline. Then, through the control device, the support assembly can be supported and fixed to the inner wall of the pipeline, so that the telescopic device can be easily removed from the interior of the pipeline to avoid being stuck inside the pipeline.

[0016] Optionally, the support assembly includes a plurality of first mounting rods uniformly fixed on the circumference of the first mounting block and a plurality of second mounting rods uniformly fixed on the circumference of the second mounting block, the first mounting rods and the second mounting rods are arranged correspondingly, and the end of the first mounting rod away from the first mounting block and the end of the second mounting rod away from the second mounting block are hingedly provided with a support block connecting the first mounting rod and the second mounting rod, the length direction of the support block is the same as the axial direction of the first mounting block and the second mounting block, and the support block can be supported on the inner wall of the pipe, and the hinge point between the first mounting rod and the support block or the hinge point between the second mounting rod and the support block can be a sliding hinge, and the sliding direction at the hinge point of the first mounting rod or the sliding direction at the hinge point of the second mounting rod is inclined to the axis of the first mounting block and the second mounting block.

[0017] By adopting the above technical solution, when the inner wall of the pipe is fixed by the support assembly, during the process of the second mounting block moving toward the first mounting block, due to the sliding hinge connection between the end of the first mounting rod and the support block or the sliding hinge connection between the end of the second mounting rod and the support block, one end of the support block can be tilted upward and abutted against the inner wall of the pipe, thereby making the support block and the pipe more firmly fixed. In addition, when the end of the support block abuts against the inner wall of the pipe, the support assembly can achieve the function of automatic locking at the position of the sliding hinge point to prevent the support block and the inner wall of the pipe from loosening.

[0018] Optionally, the end of the support block close to the sliding hinge point of the first mounting rod or close to the sliding hinge point of the second mounting rod is provided with a curved arc portion, and the arc portion is bent toward the first mounting block or the second mounting block.

[0019] By adopting the above technical solution, the arc portion provided at the end of the support block tilted toward the inner wall of the pipe can increase the contact area between the support block and the inner wall of the pipe, thereby avoiding relative sliding between the support block and the inner wall of the pipe.

[0020] Optionally, a rubber gasket is provided on a surface of the arc-shaped portion away from the first mounting rod and the second mounting rod.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a multi-pipeline synchronous traction device.

[0034] Example 1

[0035] Reference Figure 1A multi-pipeline synchronous traction device includes a control device 1, a telescopic device 2, a fixing device 3 and a driving device 4. The telescopic device 2 can be telescopically supported on the inner wall of one end of the pipeline. The control device 1 is connected to the telescopic device 2, and the control device 1 can drive the telescopic device 2 to support the inner wall of the pipeline. The fixing device 3 is connected to the end of the control device 1 away from the telescopic device 2. The driving device 4 is arranged on a side of the fixing device 3 away from the control device 1 and is connected to the fixing device 3. When the pipeline needs to be pulled, the control device 1 is first installed on the fixing device 3, and then the telescopic device 2 is driven by the control device 1 so that the telescopic device 2 can be expanded and fixed to the inner wall of the pipeline. Finally, the driving device 4 is started so that the pipeline can be pulled.

[0036] Reference Figure 1 and Figure 2 The control device 1 includes an electric adjusting rod 11, and the push rod on the electric adjusting rod 11 can control the telescopic device 2 to expand inside the pipe; the telescopic device 2 includes a first mounting block 21, a second mounting block 22 and a support assembly 23 arranged on the first mounting block 21 and the second mounting block 22. The first mounting block 21 is a circular ring structure, the second mounting block 22 is a circular block structure, and the first mounting block 21 and the second mounting block 22 are coaxially arranged. The electric adjusting rod 11 is arranged on the axis of the first mounting block 21 and the second mounting block 22. The first mounting block 21 is slidably mounted on the push rod of the electric adjusting rod 11, and the second mounting block 22 is fixed to the push rod end of the electric adjusting rod 11. The electric adjusting rod 11 can control the second mounting block 22 to move closer to or away from the direction of the first mounting block 21.

[0037] The support assembly 23 includes a plurality of first mounting rods 231 fixedly connected to the circumference of the first mounting block 21 and a plurality of second mounting rods 232 fixedly connected to the circumference of the second mounting block 22, the length direction of the first mounting rod 231 being perpendicular to the axis of the first mounting block 21, the plurality of first mounting rods 231 being evenly distributed circumferentially along the axis of the first mounting block 21, the length direction of the second mounting rods 232 being perpendicular to the axis of the second mounting block 22, and the plurality of second mounting rods 232 being evenly distributed circumferentially along the axis of the second mounting block 22. The number of the first mounting rods 231 is the same as the number of the second mounting rods 232, and the position of the first mounting rod 231 on the first mounting block 21 corresponds to the position of the second mounting rod 232 on the second mounting block 22; a support block 233 is connected to the end of the first mounting rod 231 away from the first mounting block 21 and the end of the second mounting rod 232 away from the second mounting block 22, the length direction of the support block 233 is the same as the axis direction of the first mounting block 21 and the second mounting block 22, and the support The support block 233 is hingedly connected to the first mounting rod 231 and the second mounting rod 232. A first hinge axis is fixed at the end of the first mounting rod 231, and a second hinge axis is fixed at the end of the second mounting rod 232. In the embodiment of the present application, an adjustment hole 24 is provided at the position of the support block 233 at the first hinge axis. The length direction of the adjustment hole 24 is inclined to the length direction of the support block 233, and the length direction of the adjustment hole 24 is inclined toward the direction of the second mounting rod 232. The first hinge axis is slidably hinged in the adjustment hole 24. When the push rod of the electric adjustment rod 11 pushes the second mounting block 22 to move in the direction away from the first mounting block 21, the second mounting rod 232 can pull the support block 233 so that the first hinge axis can slide in the adjustment hole 24. During the sliding process of the first hinge axis in the adjustment hole 24, the support block 233 rotates around the second hinge axis, causing the support block 233 to tilt near the end of the first mounting rod 231 and press against the inner wall of the pipe, thereby connecting and fixing the support assembly 23 to the pipe.

[0038] Reference Figure 1 and Figure 2The first and second mounting rods 231 and 232 are both retractable structures. The end away from the telescopic rod can be fixed to the first mounting block 21 or the second mounting block 22, and the end of the telescopic rod away from the fixed rod can be hinged to the support block 233. A fastening screw is provided at the end of the fixed rod close to the telescopic rod. The fastening screw is threadedly tightened on the fixed rod and can be tightened against the telescopic rod. When the telescopic rod is extended from the inside of the fixed rod, the fastening screw can fix the fixed rod and the telescopic rod. The first mounting rod 231 and the second mounting rod 232 are telescopic structures, so that the support assembly 23 can be suitable for pipes of different diameters, thereby improving the applicability of the support assembly 23; in addition, the telescopic structure of each first mounting rod 231 and the second mounting rod 232 can be independently telescopically adjusted. Therefore, when pulling the pipe, different types of pipes can be pulled, such as round pipes, square pipes, etc. When supporting and fixing different pipes, the corresponding first mounting rod 231 and the second mounting rod 232 can be stretched so that the support block 233 and the arc-shaped portion 25 can be supported on the inner wall of the pipe.

[0039] A push ring is fixed on the push rod of the electric adjusting rod 11, and the push ring is located on the side of the first mounting block 21 away from the second mounting block 22. When the push rod of the electric adjusting rod 11 is extended, the arc-shaped portion 25 on the support block 233 abuts against the inner wall of the pipe. The push rod on the electric adjusting rod 11 continues to be pushed out. Under the action of the push ring, the push ring can push the support assembly 23 as a whole to continue moving deeper into the pipe, increasing the sliding distance between the support assembly 23 and the pipe, and avoiding the support assembly 23 from easily detaching from the inside of the pipe when the external force is large.

[0040] Reference Figure 1 and Figure 2The cam 33 is a substantially rectangular strip having two bosses 31 and 32 and a plurality of bosses 32 connected thereto. The bosses 31 and 32 are arranged on a substantially rectangular strip having two bosses 31 and 32 connected thereto. The bosses 31 and 32 are arranged on the same side of the cam 33 and the cam 33 is a substantially rectangular strip having two bosses 31 and 32 connected thereto. The U-shaped lock handle 351 is connected to the upper guard plate 31, and a pair of lock rotating cylinders 352 are fixedly connected to the plate surface of the upper guard plate 31. The two ends of the lock handle 351 are inserted into the lock rotating cylinder 352, and the two ends of the lock handle 351 pass through the lock rotating cylinder 352. A U-shaped fixed lock 353 is fixedly connected to both ends of the lock handle 351. The two fixed locks 353 are both perpendicular to the lock handle 351, and the two fixed locks 353 can be buckled. On the edge of the upper guard plate 31 and the lower guard plate 32 away from the rotating connecting shaft 33, when the end of the electric adjusting rod 11 is fixed in the mounting hole 34, the upper guard plate 31 and the lower guard plate 32 first clamp the end of the electric adjusting rod 11, and then the staff rotates the locking handle 351 so that the fixed lock 353 can connect and fasten the upper guard plate 31 and the lower guard plate 32 to prevent the end of the electric adjusting rod 11 from falling off from the mounting hole 34 when the electric adjusting rod 11 is subjected to a large traction force.

[0041] Reference Figure 1 and Figure 2 , a snap-fit ​​hole 36 is provided on one side of the upper guard plate 31 and the lower guard plate 32 close to the rotating connecting shaft 33 and at the position of the mounting hole 34, and a snap-fit ​​ring 37 is fixedly connected to the end face of the electric adjusting rod 11. When the end of the electric adjusting rod 11 is installed on the mounting hole 34, the snap-fit ​​ring 37 can be snap-fitted into the snap-fit ​​hole 36. When the fixing device 3 is towing a heavier pipe or multiple pipes, the matched snap-fit ​​ring 37 and the snap-fit ​​hole 36 can firmly fix the end of the electric adjusting rod 11 to the mounting hole 34, preventing the end of the electric adjusting rod 11 from falling off from the mounting hole 34, causing the pipe to be unable to be towed normally.

[0042] The driving device 4 includes a plurality of semi-circular lifting ears 41 fixed on the rotating connecting shaft 33. The plurality of lifting ears 41 are evenly distributed along the length direction of the rotating connecting shaft 33. The driving device 4 also includes an electric winch. One end of the electric winch can be fixed on the lifting ear 41. When it is necessary to pull the pipeline, the electric winch is started to pull the fixing device 3, so that the pipeline is subjected to the pulling force of the electric winch to pull the pipeline.

[0043] The control device 1 also includes a plurality of power interfaces 12 arranged on the rotating connecting shaft 33 and an electric control switch 13 arranged on the rotating connecting shaft 33. The plurality of power interfaces 12 are connected to each other, and the number of power interfaces 12 is the same as the number of mounting holes 34. When the electric adjustment rod 11 is set on the mounting hole 34, the power interface 12 is electrically connected to the electric adjustment rod 11. The electric control switch 13 can control the on and off of each power interface 12, so that the electric adjustment rod 11 controls the support assembly 23 to support it on the inner wall of the pipe.

[0044] The implementation principle of a multi-pipe synchronous traction device in an embodiment of the present application is as follows: when it is necessary to pull a pipe, the staff fixes one end of the electric adjustment rod 11 to the mounting hole 34 between the upper guard plate 31 and the lower guard plate 32, and connects the electric adjustment rod 11 to the corresponding power interface 12, and then installs the telescopic device 2 into the corresponding pipe. According to the diameter of the traction pipe, the length of the first mounting rod 231 and the second mounting rod 232 is adjusted so that the support block 233 and the arc-shaped portion 25 first contact the inner wall of the pulled pipe, and the electric adjustment rod 11 is started. Under the action of the adjustment hole 24 on the support block 233, the arc-shaped portion 25 is tightened to the inner wall of the pipe, and finally the winch is started to start pulling the pipe.

[0045] Example 2

[0046] Reference Figure 1 and Figure 2The difference between the embodiment of the present application and the embodiment 1 is that one end of the first mounting rod 231 is hinged to the first mounting block 21, and the other end is hinged to the support block 233, one end of the second mounting rod 232 is hinged to the second mounting block 22, and the other end is hinged to the support block 233. The first mounting rod 231 and the second mounting rod 232 are a telescopic structure with the same structure as that in the embodiment 1. The first mounting block 21 is fixed to the electric adjustment rod 11. When the pipeline needs to be fixed, the push rod of the electric adjustment rod 11 is extended first, and the second mounting block 22 gradually moves away from the first mounting block 21. Under the action of the first mounting rod 231 and the second mounting rod 232, multiple support blocks 233 approach the first mounting block 21 and the second mounting block 22. When the support assembly 23 is extended into the interior of the pipeline, the electric adjustment rod 11 is started, and the push rod is gradually retracted onto the electric adjustment rod 11, so that multiple support blocks 233 can be pressed against the inner wall of the pipeline, thereby achieving the fixation of the pulled pipeline.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
