Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pipelines, and specifically relates to a vehicle-mounted transport rack for natural gas pipelines. Background Art

[0002] A natural gas pipeline refers to a pipeline that transports natural gas from the production site or treatment plant to the urban gas distribution center or industrial enterprise users, also known as a gas transmission pipeline. Using natural gas pipelines to transport natural gas is a way to transport large amounts of natural gas on land. When natural gas pipelines are transported over long distances, special vehicles are required for transportation operations.

[0003] Currently, the structures of existing vehicle-mounted transport racks for natural gas pipelines mostly directly bind the pipelines to the transport racks. However, when the vehicle vibrates, due to different vibration amplitudes, the pipelines will be squeezed against each other, resulting in pipeline damage problems, affecting the quality of natural gas pipelines. Therefore, it is urgent to design a vehicle-mounted transport rack for natural gas pipelines to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a vehicle-mounted transport rack for natural gas pipelines to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A vehicle-mounted transport rack for natural gas pipelines includes a vehicle-mounted support frame. A plurality of equally spaced fixed plates are fixedly installed on the inner wall of the vehicle-mounted support frame, and displacement mechanisms are fixedly arranged at the middle positions of the tops of the fixed plates. Support platforms are arranged on the tops of the displacement mechanisms. Equally spaced guide grooves are formed in the inner walls at both ends of the vehicle-mounted support frame, and guide plates inserted into the guide grooves are fixed at both ends of the support platforms. A plurality of equally spaced second pulleys are rotatably connected to the bottoms of the guide plates, and the outer walls of the second pulleys are in contact with the bottom inner walls of the guide grooves. A plurality of columns of equally spaced lower supporting pads are fixedly installed on the top of the support platform, and the same natural gas pipeline body is placed on the tops of the lower supporting pads in the same column. A pressing and fixing assembly is arranged on the top of the support platform.

[0007] Further, the displacement mechanism includes support seats fixedly installed on both sides of the middle position of the top of the fixed plate. A gear is rotatably connected between the opposite ends of the two support seats. A forward and reverse motor for driving the gear to rotate is fixedly installed at one end of the outer wall of one of the support seats. Equally spaced tooth grooves are formed in the middle position of the bottom of the support platform, and the inner walls of the tooth grooves are meshed with the outer wall of the gear.

[0008] Further, sliding grooves are formed at the tops of the support bases, and support bars inserted into the sliding grooves are fixed to both sides of the bottom of the support platform. First pulleys are rotatably connected to the bottom sides of both sides of the support bars at equal intervals, and the first pulleys are slidably arranged on the inner walls of the sliding grooves.

[0009] Further, the pressing and fixing assembly includes connection grooves formed on both outer sides of the two ends of the vehicle-mounted support frame at equal intervals, and an H-shaped lifting plate is inserted into the four connection grooves on the same horizontal plane. The same U-shaped frame is fixed to one end of the H-shaped lifting plate. Hydraulic cylinders are fixedly installed at the middle positions of the outer walls of the two ends of the vehicle-mounted support frame, and the piston ends of the hydraulic cylinders are fixedly connected to the middle positions of the U-shaped frame. Upper pressing pads are fixedly installed at the middle positions of the bottom of the H-shaped lifting plate at equal intervals, and the upper pressing pads are arranged directly above the natural gas pipeline body.

[0010] Further, arc-shaped surfaces are arranged at the tops of the lower support pads and the bottoms of the upper pressing pads, and anti-slip grooves are formed at equal intervals at the tops of the lower support pads and the bottoms of the upper pressing pads.

[0011] Further, protective pads are fixedly installed at equal intervals on the inner walls of the two ends of the vehicle-mounted support frame, and the positions of the protective pads correspond to the two ends of the natural gas pipeline body.

[0012] Further, a control device is fixedly installed on the vehicle-mounted support frame, and the control device is connected to the forward and reverse motor and the hydraulic cylinder for control.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, through the vehicle-mounted support frame, support platform, lower support pad, natural gas pipeline body, and pressing and fixing assembly provided, a placement measure for multiple natural gas pipeline bodies can be formed on the vehicle-mounted support frame, facilitating the transportation of a certain amount of natural gas pipeline bodies at one time, and using the pressing and fixing assembly in cooperation with the support platform and lower support pad to press and fix the natural gas pipeline body, ensuring the stability of the pipeline during transportation. Moreover, through the cooperation of the lower support pad and the upper pressing pad, the natural gas pipeline bodies can be separately placed, avoiding the phenomenon that the pipelines will be mutually extruded when the transport vehicle vibrates, and avoiding the problem of pipeline extrusion damage.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5, in the embodiment of the present utility model, a natural gas pipeline transport rack includes a vehicle-mounted support frame 1. A plurality of equally spaced fixed plates 2 are fixedly installed on the inner wall of the vehicle-mounted support frame 1, and a displacement mechanism 3 is fixedly arranged at the middle position of the top of each fixed plate 2. A support platform 4 is arranged on the top of each displacement mechanism 3. The displacement mechanism 3 includes support seats 303 fixedly installed on both sides of the middle position of the top of the fixed plate 2. A gear 302 is rotatably connected between one ends of the opposite sides of the two support seats 303. A forward and reverse motor 301 for driving the rotation of the gear 302 is fixedly installed at one end of the outer wall of one of the support seats 303. Equally spaced tooth grooves 305 are formed at the middle position of the bottom of the support platform 4, and the inner wall of the tooth groove 305 meshes with the outer wall of the gear 302. Equally spaced guide grooves 9 are formed on the inner walls at both ends of the vehicle-mounted support frame 1, and guide plates 12 inserted into the guide grooves 9 are fixed at both ends of the support platform 4. Equally spaced second pulleys 13 are rotatably connected to the bottom of the guide plates 12, and the outer wall of the second pulley 13 is in contact with the bottom inner wall of the guide groove 9. A plurality of equally spaced lower support pads 5 are fixedly installed on the top of the support platform 4, and the same natural gas pipeline body 6 is placed on the top of the same column of lower support pads 5. A pressing and fixing assembly 8 is arranged on the top of the support platform 4. The pressing and fixing assembly 8 includes connection grooves 801 equally spaced on both sides of the outer walls at both ends of the vehicle-mounted support frame 1, and the same H-shaped lifting plate 802 is inserted into the four connection grooves 801 on the same horizontal plane. A U-shaped frame 804 is fixed at one end of the H-shaped lifting plate 802. Hydraulic cylinders 805 are fixedly installed at the middle positions of the outer walls at both ends of the vehicle-mounted support frame 1, and the piston ends of the hydraulic cylinders 805 are fixedly connected to the middle position of the U-shaped frame 804. Equally spaced upper pressing pads 803 are fixedly installed at the middle position of the bottom of the H-shaped lifting plate 802, and the upper pressing pads 803 are arranged directly above the natural gas pipeline body 6. The top of the lower support pad 5 and the bottom of the upper pressing pad 803 are both arc-shaped, and equally spaced anti-slip grooves are formed on the top of the lower support pad 5 and the bottom of the upper pressing pad 803, forming an installation measure for multiple natural gas pipeline bodies 6, facilitating the transportation of a certain amount of natural gas pipeline bodies 6 at one time, and using the pressing and fixing assembly 8 to cooperate with the support platform 4 and the lower support pads 5 to press and fix the natural gas pipeline body 6, ensuring the stability of the pipeline during transportation, avoiding the phenomenon that the pipelines will squeeze each other when the transport vehicle vibrates, and moreover, the displacement mechanism 3 can be used to drive the support platform 4 to form a sliding-in and sliding-out effect on the vehicle-mounted support frame 1, facilitating the driving of multiple natural gas pipeline bodies 6 to be moved in and out of the vehicle-mounted support frame 1 in sequence, and facilitating loading and unloading.

[0024] Specifically, chutes 304 are formed at the tops of the support bases 303, and support bars 10 inserted into the chutes 304 are fixed to both sides of the bottom of the support platform 4. First pulleys 11 distributed at equal intervals are rotatably connected to the bottom sides of both sides of the support bars 10 through pin shafts. The first pulleys 11 are slidably arranged on the inner walls of the chutes 304. The sliding of the first pulleys 11 and the chutes 304 facilitates the movement of the support platform 4.

[0025] Specifically, protective pads 7 distributed at equal intervals are fixedly installed on the inner walls of both ends of the vehicle-mounted support frame 1, and the positions of the protective pads 7 correspond to both ends of the natural gas pipeline body 6. The protective pads 7 form protective measures for both ends of the natural gas pipeline body 6 on the vehicle-mounted support frame 1, avoiding the problem that the natural gas pipeline body 6 impacts the vehicle-mounted support frame 1 after breaking away from the lower support pad 5 and the upper pressing pad 803 due to excessive inertia, and preventing damage to both ends of the natural gas pipeline body 6.

[0026] Specifically, a control device is fixedly installed on the vehicle-mounted support frame 1, and the control device is controllably connected to the forward and reverse motor 301 and the hydraulic cylinder 805.

[0027] The working principle of the present utility model is as follows: During use, the user successively uses a hoisting device to hoist the natural gas pipeline body 6 onto the support platform 4 and the lower support pad 5. The forward and reverse motor 301 in the displacement mechanism 3 drives the gear 302 to rotate. By the meshing action of the gear 302 and the tooth grooves 305, the support platform 4 is driven to move on the vehicle-mounted support frame 1, causing the support bars 10 and the first pulleys 11 to slide on the chutes 304, and also causing the second pulleys 13 and the guide plates 12 to slide in the guide grooves 9, facilitating the sequential movement of multiple layers of natural gas pipeline bodies 6 into the vehicle-mounted support frame 1 for easy loading. Then, the height of the U-shaped frame 804, the H-shaped lifting plate 802, and the upper pressing pad 803 is adjusted by the hydraulic cylinder 805 in the pressing and fixing assembly 8, and the lower support pad 5 is used to press and fix the natural gas pipeline body 6, and the natural gas pipeline bodies 6 are separately placed to avoid the phenomenon that the pipelines will squeeze each other when the transport vehicle vibrates. When unloading, the user separates the upper pressing pad 803 from the natural gas pipeline body 6 through the reset action of the pressing and fixing assembly 8, and drives the support platform 4 to slide out of the vehicle-mounted support frame 1 through the reverse movement of the displacement mechanism 3, facilitating the sequential movement of multiple layers of natural gas pipeline bodies 6 out of the vehicle-mounted support frame 1 for easy loading and unloading.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
