Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, and in particular to a pipeline transportation device for complex terrain. Background Technology

[0002] When installing cables in mountainous areas, in order to prevent damage from falling rocks, rock abrasion, rainwater erosion, or corrosion from damp soil, the cables are usually run through conduits. The conduits provide a protective barrier for the cables, reducing the damage from the natural environment and extending their service life.

[0003] Currently, a pipeline transportation device for complex geographical conditions has emerged (publication number CN119489736A), including an arc-shaped pipeline support component. The arc-shaped support component has an arc-shaped structure, with a bearing connecting pipe vertically installed at the center of its bottom. The lower part of the bearing connecting pipe is connected to a ball bearing, which is fixed above the bearing support device. The bearing support device is made of channel steel, with four sets of caster drive devices symmetrically installed on both sides of the channel steel, each connected to one of the four sets of casters. The bearing support device contains a power unit. The four sets of casters can transport the pipeline to be installed later on the already installed pipe section, with less influence from terrain conditions, thus improving transportation efficiency.

[0004] Existing pipeline transportation devices in complex geographical conditions have casters installed on both sides of the channel steel, with all four sets of casters set vertically. The vertically set casters only contact the top of the pipeline, resulting in weak anti-tilting ability and poor stability. In addition, due to the influence of the pipeline shape, the wear degree of different positions of the casters is different, affecting the stability of transportation. The fixed position of the casters can only solve the problem of uneven wear by replacing the casters, which is costly. Utility Model Content

[0005] To address the technical problem in the existing pipeline transportation devices for complex geographical conditions mentioned above, where all casters are vertically installed and have weak anti-tilting ability, this utility model provides a pipeline transportation device for complex terrain.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a pipeline transportation device for complex terrain, including a first support frame and a second support frame rotatably connected. Both the first and second support frames are arc-shaped supports to better conform to the shape of the pipeline, enhance the contact stability between the device and the pipeline, and help maintain the relative position of the device and the pipeline during transportation in complex terrain. The first support frame opens downward and the second support frame opens upward. The first support frame is located below the second support frame. Several rollers are installed at intervals along the arc direction on the inner circle of the first support frame, which can distribute the weight of the transported pipeline, reduce the force on individual rollers, improve the stability during transportation, reduce the risk of damage to the pipeline surface, and at the same time increase the contact range between the pipeline transportation device and the fixed pipeline in the circumferential direction, effectively improving its support stability and anti-tilting ability.

[0008] Preferably, the first support frame and the second support frame are rotatably connected by a rotating shaft. The rotating shaft is set vertically and can adapt to fixed pipes with different angles and degrees of curvature. During transportation, when encountering a curved pipe, the two support frames can adjust their angles by rotating relative to each other to always maintain a good fit with the fixed pipe. At the same time, the transportation angle of the transport pipe is changed, which greatly improves the adaptability of the device in complex terrain.

[0009] Preferably, a bearing seat is fixedly provided at the center of the outer ring of the first support frame. One end of the rotating shaft is rotatably connected to the bearing seat, and the other end of the rotating shaft is detachably connected to the second support frame. The bearing seat provides stable support for the rotating shaft, reduces friction when the rotating shaft rotates, and makes the relative rotation between the first support frame and the second support frame smoother. The detachable connection between the rotating shaft and the second support frame allows for the replacement of second support frames with different radii to meet the needs of pipeline transportation of different specifications, resulting in strong overall adaptability.

[0010] Preferably, a connecting seat is welded and fixed at the center of the outer ring of the second support frame, and the rotating shaft is threaded to the connecting seat. The threaded connection not only ensures the firmness of the connection between the second support frame and the rotating shaft, but also facilitates the disassembly and assembly of the second support frame and the rotating shaft, greatly improving the ease of use of the device.

[0011] Preferably, at least three rollers are provided, with one roller set vertically and the remaining rollers set opposite each other on both sides of the vertically set roller. The vertically set roller mainly bears the vertical weight of the pipeline, while the rollers set opposite each other on both sides can cooperate with the fixed pipeline to play a lateral restraint role. This can effectively prevent the transport device from lateral displacement or shaking during transportation, so that the rollers can always move smoothly along the pipeline trajectory, with strong anti-tilting ability, improving the stability and safety of transportation.

[0012] Preferably, a mounting base is fitted onto the first support frame, and a tightening limit rod is threaded onto the mounting base. One end of the tightening limit rod abuts against the outer ring of the first support frame. The roller is rotatably mounted on the mounting base. The tightness between the tightening limit rod and the outer ring of the first support frame can be adjusted according to actual needs. When it is necessary to fix the position of the roller, tighten the tightening limit rod to make it firmly abut against the first support frame, preventing the mounting base from sliding on the first support frame and ensuring the positional stability of the roller during operation. When it is necessary to adjust the position of the roller, simply loosen the tightening limit rod. The operation is simple and convenient. Furthermore, if uneven wear of the roller is found during transportation, the position of the roller can be changed by adjusting the tightening limit rod, thereby changing the contact position between the roller and the outer wall of the fixed pipe, making the wear of the roller more uniform and extending the service life of the roller.

[0013] Preferably, the side wall of the first support frame is provided with a groove along its arc direction, and the inner wall of the mounting seat is fixedly provided with a protrusion. The protrusion is slidably connected with the groove, providing guidance for the movement of the mounting seat on the first support frame, so that the mounting seat can slide smoothly along the arc direction of the first support frame.

[0014] Preferably, a handrail is detachably installed at the end of the first support frame. The handrail facilitates the operation of the pipeline transportation device by the staff. During the movement, when encountering a bend, the second support frame can be directly rotated through the handrail, making operation convenient.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] 1. An arc-shaped first support frame and a second support frame are installed. The first support frame opens downward and is equipped with rollers, which can better conform to the shape of the pipeline and work with the pipeline to provide lateral restraint. This can effectively prevent the pipeline transport device from lateral displacement or shaking during transportation, and has strong anti-tilting ability, which effectively improves the stability and safety of transportation. The second support frame opens upward and is rotatably connected to the first support frame. It can support the transport pipeline, and when encountering a curved pipeline during transportation, the two support frames can adjust their angles by relative rotation to always maintain a good fit with the fixed pipeline. At the same time, it can change the transport angle of the pipeline, which greatly improves the adaptability of the device in complex terrain.

[0017] 2. The roller is slidably connected to the first support frame via a mounting base, and the mounting base is fixed to the first support frame by a tightening limit rod. When it is necessary to fix the position of the roller, tighten the tightening limit rod to make it firmly abut against the first support frame, preventing the mounting base from sliding on the first support frame and ensuring the positional stability of the roller during operation. When it is necessary to adjust the position of the roller, simply loosen the tightening limit rod. The operation is simple and convenient, and the contact position between the roller and the outer wall of the fixed pipe can be adjusted to make the wear of the roller more uniform and extend the service life of the roller.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] In a typical embodiment of this utility model, such as Figures 1-2As shown, a pipeline transportation device for complex terrain is proposed, comprising: a first support frame 1, rollers 3, bearing seats 4, a rotating shaft 5, and a second support frame 7. Both the first support frame 1 and the second support frame 7 are arc-shaped supports. The opening of the first support frame 1 faces downward, and the opening of the second support frame 7 faces upward. The first support frame 1 is used to connect with the fixed pipeline, and the second support frame 7 is used to support the pipeline. Several rollers 3 are installed at intervals along the arc direction on the inner ring of the first support frame 1 so that they can contact the side and top of the outer ring of the fixed pipeline to improve the support stability and anti-tilting ability. The bearing seats 4 are fixedly set at the center of the outer ring of the first support frame 1 by welding or other means. A ball bearing is installed in the bearing seats 4. The rotating shaft 5 is set vertically, and one end of the rotating shaft 5 is fixedly connected to the ball bearing in the bearing seats 4, so that the rotating shaft 5 and the bearing seats 4 are rotatably connected. The end of the rotating shaft 5 away from the bearing seats 4 is provided with an external thread, and the rotating shaft 5 is detachably connected to the second support frame 7 by a threaded connection.

[0025] The second support frame 7 can rotate relative to the first support frame 1 with the cooperation of the rotating shaft 5 and the rotating shaft seat 4. During transportation, it is convenient to adjust the transportation angle of the transportation pipeline at the bend, which effectively improves its throughput capacity.

[0026] To improve support and anti-tilting capacity, at least three rollers 3 are provided. One roller 3 is vertically arranged, and the other rollers 3 are arranged opposite each other on both sides of the vertical roller 3. The vertically arranged roller 3 is used to contact the top of the fixed pipe, and the inclined roller 3 is used to contact the side of the fixed pipe. While providing high support stability, the oppositely arranged rollers 3 can also be used to limit the position of the pipe transport device and prevent tilting.

[0027] In this embodiment, the roller 3 is fixedly mounted on the first support frame 1 by the mounting base 2. The mounting base 2 is fixedly connected to the first support frame 1 by bolts, and the roller 3 is rotatably connected to the mounting base 2 by a rotating shaft.

[0028] In other embodiments, the roller 3 can also be movably mounted on the first support frame 1, specifically as follows: Figure 2As shown, the roller 3 is rotatably mounted on the mounting base 2 via a rotating shaft. The mounting base 2 is sleeved on the first support frame 1, and a groove 9 is provided on the side wall of the first support frame 1 along its arc direction. A protrusion 11 is fixedly provided on the inner wall of the mounting base 2. The protrusion 11 is inserted into the groove 9 and is slidably connected to the groove 9, so that the mounting base 2 can be adjusted along the groove 9 to change the position of the roller 3. A threaded hole is provided on the mounting base 2, and a tightening limit rod 10 is threadedly connected inside the threaded hole. When the position of the mounting base 2 is adjusted to the correct position, the tightening limit rod 10 can be turned to tighten and limit the first limit frame 1 and the mounting base 2, so as to fix the relative position between the mounting base 2 and the first limit frame 1.

[0029] To facilitate the use of the clamping limit rod 10, an operating part for hand-squeezing / wrench rotation can be fixedly provided at one end of the clamping limit rod 10 that extends out of the mounting base 2; an abutment plate is fixedly provided at the end of the clamping limit rod 10 that abuts against the outer ring wall of the first support frame 1. The abutment plate is made of rubber, which can reduce the squeezing damage of the clamping limit rod 10 to the outer ring of the first support frame 1 on the one hand, and increase the contact area and friction between the clamping limit rod 10 and the outer ring of the first support frame 1 on the other hand, thereby improving the limiting effect.

[0030] A connecting seat 6 is welded and fixed at the center of the outer ring of the second support frame 7. The connecting seat 6 has an internal thread, and the outer wall of the end of the rotating shaft 5 is provided with an external thread. Thus, the rotating shaft 5 and the second support frame 7 are detachably connected by threaded connection. In pipeline transportation, the second support frame 7 with different radii can be replaced to meet the needs of pipeline transportation of different specifications, and the overall adaptability is strong.

[0031] A handrail 8 is detachably installed at the end of the first support frame 7. The handrail 8 is vertically arranged. Specifically, the end of the first support frame 7 is provided with a threaded hole, and the end of the handrail 8 connected to the first support frame 7 is provided with an external thread. The handrail 8 is detachably connected to the first support frame 7 through a threaded connection. The handrail 8 facilitates the operation of the pipeline transportation device by the staff during transportation, especially the rotation of the second support frame 7 around the axis.

[0032] Understandably, one or two handrails can be installed, and the specific number can be selected according to actual needs. No further restrictions are imposed here.

[0033] In this embodiment, a suitable number of pipeline transport devices are selected. When using the pipeline transport devices, the first support frame 1 of all pipeline transport devices is first placed on the fixed pipeline, and the transport pipeline is placed between all the second support frames 7. The second support frames 7 are used to support the transport pipeline. Each worker operates one pipeline transport device. The worker holds the handrail 8 with one hand and places the other hand on the transport pipeline to push it along the fixed pipeline. During the movement, when encountering a bend, the transport angle of the transport pipeline can be adjusted by directly rotating the second support frame 7.

[0034] Understandably, in order to reduce costs and facilitate the carrying and use of the pipeline transportation device, this embodiment omits electric drive components such as motors and power supplies, thereby simplifying the overall structure and weight of the pipeline transportation device.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
