Description

Technical Field

[0001] This invention relates to the field of pipeline transportation, specifically to a ribbed steel pipe transportation base. Background Technology

[0002] Steel pipes are hollow, long, round steel materials, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Due to their large size, they often require transport bases or trolley systems for assistance during ground transportation.

[0003] For example, Chinese utility model patent CN 213832850 U discloses a shock-absorbing base for transporting stainless steel pipes, including a base, a placement seat, a steel pipe, connecting bolts, a spring, a pulley assembly, and an adjustment groove. The base has an adjustment groove, and the placement seat is fixed to the base via the connecting bolts passing through the adjustment groove. The spring is movably fitted onto the connecting bolts and located between the placement seat and the base. The pulley assembly is installed on the base between the two placement seats, and the steel pipe is placed between the two placement seats above the pulley assembly. The pulley assembly includes a limiting rod, a pulley frame, a rotating shaft, a pulley, a screw, and a pin hole. This shock-absorbing base for transporting stainless steel pipes, through the cooperation of the connecting bolts and the spring, elastically connects the placement seat and the base, thereby buffering and reducing vibrations generated by the vehicle body during the transport of the steel pipes.

[0004] However, as mentioned above, the existing transport base cannot solve the problem of adding steel pipes with ribs such as stiffening rings and waterproof wing rings; while the trolley system has problems such as high requirements for ground flatness and hardening treatment, high cost due to the need to lay long tracks, and inconvenience issues such as the inability to quickly move, add or remove tracks after the tracks are laid to keep up with the progress of the project.

[0005] Therefore, there is an urgent need for a ribbed steel pipe transport base. Summary of the Invention

[0006] To avoid the aforementioned problems in the prior art, the purpose of this invention is to provide a ribbed steel pipe transport base.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a ribbed steel pipe transport base, comprising a base body, several transport guide wheel mechanisms and a limiting component, wherein each transport guide wheel mechanism comprises a guide wheel group, a sliding adjustment component and a reset component; The guide wheel assembly is mounted on the base body via a sliding adjustment component; the sliding adjustment component includes a rotating support arm, a sliding support arm, a slider, and a slide groove; one end of the rotating support arm is hinged to the base body, and the other end is hinged to the guide wheel assembly; one end of the sliding support arm is hinged to the guide wheel assembly, and the other end is connected to the slide groove via the slider; the slide groove is mounted on the base body, and a reset component is also mounted within the slide groove, the reset component abutting against the slide groove; The limiting component includes a limiting block and a limiting lifting mechanism. The bottom of the slide is provided with a limiting through hole, and the limiting block is disposed in the limiting through hole. The limiting lifting mechanism adjusts the movement of the limiting block along the limiting through hole to block or avoid the sliding of the slider.

[0008] The purpose of the above scheme is to adjust the relative height of the guide wheel assembly by means of a sliding adjustment component. When the rib section of the steel pipe passes the transport base, the rib protruding from the outer wall of the steel pipe will press down on the guide wheel assembly. At this time, the limit lifting mechanism controls the limit block to descend, avoiding the movement of the slider. The sliding support arm at the bottom of the guide wheel assembly moves along the slide groove, adjusting the relative height of the guide wheel assembly to facilitate the passage of the rib. After the rib passes the guide wheel assembly of the transport base, the sliding support arm is rebounded back to its original position by the reset component. The limit lifting mechanism controls the limit block to rise, blocking the movement of the slider, so that the guide wheel assembly continues to support the outer wall of the steel pipe.

[0009] The present invention is further configured such that the transport guide wheel mechanism is arranged on the base body in a circumferential direction, the guide wheel assembly includes two rubber wheels and a connecting shaft, a rubber wheel is respectively provided at both ends of the connecting shaft, and the rotating support arm and the sliding support arm are respectively hinged to the connecting shaft.

[0010] The invention is further configured such that the rubber wheel is frustum-shaped, and the generatrix of the frustum of the rubber wheel is tangent to the outer wall of the steel pipe being transported.

[0011] The purpose of the above structure is to reduce friction with the steel pipe during transportation, thus facilitating transportation activities.

[0012] The present invention is further configured such that the reset component includes a baffle and a spring, one end of the spring is fixed on the slide groove, and the other end is connected to the baffle, the baffle abutting against the slider.

[0013] The purpose of the above structure is to set a baffle as a limiting mechanism, and a spring is set on the baffle to realize the reset of the sliding arm.

[0014] The present invention is further configured such that a fixing groove is provided at the bottom of the slider, and when the slider is in the reset state, the position of the fixing groove corresponds to the position of the limiting through hole.

[0015] The present invention is further configured such that the limiting component further includes a drive motor and a drive gear, the limiting lifting mechanism includes a gear disk, the output end of the drive motor is connected to the drive gear, and the drive gear meshes with the gear disk; Two trapezoidal lifting adjustment blocks are provided on the upper end surface of the gear disk along the circumferential direction. One end of the limiting block is located in the limiting through hole, and the other end abuts against the upper end surface of the gear disk.

[0016] The purpose of the above structure is to drive the gear disk to rotate via a drive motor, thereby causing the limit block to move along the lifting adjustment block on the upper end face of the gear disk. When the limit block is at the top of the lifting adjustment block, the limit block extends into the fixing groove at the bottom of the slider, blocking the movement of the slider; when the limit block is at the bottom of the lifting adjustment block, the relative height of the limit block decreases, leaving the fixing groove at the bottom of the slider, thus avoiding the movement of the slider.

[0017] The present invention is further configured such that the side of the limiting block that contacts the lifting adjustment block is configured as an arc-shaped transition surface, which facilitates the sliding of the limiting block along the lifting adjustment block.

[0018] The present invention is further configured such that the bottom of the slide groove of each group of transport guide wheel mechanism is provided with the gear disk and the limiting block, and the adjacent gear disks are linked by bevel gears.

[0019] The present invention is further configured such that the ribbed steel pipe transport base also includes a proximity sensor, which is disposed on the base body near the material receiving end of the transported steel pipe.

[0020] The purpose of the above structure is to monitor the position of the rib plate by a proximity sensor, send a signal to control the drive motor to drive the gear disk to rotate, and drive the limit block to disengage from the fixed groove at the bottom of the slider.

[0021] The present invention is further configured such that the reset assembly includes a Hall sensor and a trigger head; the Hall sensor is disposed at the end of the slide away from the reset assembly, and the trigger head is disposed on the slider.

[0022] The purpose of the above structure is that when the rib passes the rubber wheel, the sliding arm is rebounded back to its original position by the spring, the magnetic head on the slider triggers the Hall sensor, the Hall sensor sends a signal, the drive motor drives the gear disk to rotate, and the limit block extends into the fixing groove at the bottom of the slider for fixing.

[0023] In summary, the beneficial effects of the above-mentioned technical solution of the present invention are as follows: This invention adjusts the relative height of the guide wheel assembly using a sliding adjustment component. When the rib section of the steel pipe passes the transport base, the rib protruding from the outer wall of the steel pipe presses down on the guide wheel assembly. At this time, the limiting lifting mechanism controls the limiting block to descend, avoiding the movement of the slider. The sliding support arm at the bottom of the guide wheel assembly moves along the slide groove, adjusting the relative height of the guide wheel assembly to facilitate the passage of the rib. After the rib passes the guide wheel assembly of the transport base, the sliding support arm is rebounded back to its original position by the reset component. The limiting lifting mechanism controls the limiting block to rise, blocking the movement of the slider, allowing the guide wheel assembly to continue supporting the outer wall of the steel pipe, thus realizing the transport of the ribbed steel pipe.

[0035] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of the present invention, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of the present invention.

[0036] Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0037] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0038] Example: like Figures 1-9 As shown in the preferred embodiment of the present invention, a ribbed steel pipe transport base includes a base body 100, a plurality of transport guide wheel mechanisms 200 and a limiting component 300. Each transport guide wheel mechanism 200 includes a guide wheel group, a sliding adjustment component and a reset component 400. The guide wheel assembly is mounted on the base body 100 via a sliding adjustment component. The sliding adjustment component includes a rotating support arm 203, a sliding support arm 202, a slider 204, and a slide groove 205. One end of the rotating support arm 203 is hinged to the base body 100, and the other end is hinged to the guide wheel assembly. One end of the sliding support arm 202 is hinged to the guide wheel assembly, and the other end is connected to the slide groove 205 via the slider 204. The slide groove 205 is mounted on the base body 100, and a reset component 400 is also provided in the slide groove 205, which abuts against the slide groove 205. Combination Figures 4-5 As shown, the limiting component 300 includes a limiting block 305 and a limiting lifting mechanism. The bottom of the slide groove 205 is provided with a limiting through hole 206. The limiting block 305 is disposed in the limiting through hole 206. The limiting lifting mechanism adjusts the limiting block 305 to rise or fall along the limiting through hole 206 to block or avoid the sliding of the slider 204.

[0039] The relative height of the guide wheel assembly is adjusted by the sliding adjustment component. When the rib section of the steel pipe passes the transport base 100, the rib protruding from the outer wall of the steel pipe will press down on the guide wheel assembly. At this time, the limit lifting mechanism controls the limit block 305 to descend, avoiding the movement of the slider 204. The sliding support arm 202 at the bottom of the guide wheel assembly moves along the slide groove 205 to adjust the relative height of the guide wheel assembly, facilitating the passage of the rib. After the rib passes the guide wheel assembly of the transport base 100, the sliding support arm 202 is rebounded back to its original position by the reset component 400. The limit lifting mechanism controls the limit block 305 to rise, blocking the movement of the slider 204, so that the guide wheel assembly continues to support the outer wall of the steel pipe.

[0040] Combination Figures 2-3 As shown, the transport guide wheel mechanism 200 is arranged on the base body 100 along the circumferential direction. In this embodiment, three sets of transport guide wheel mechanisms 200 are provided. The guide wheel set includes two rubber wheels 201 and a connecting shaft. A rubber wheel 201 is provided at each end of the connecting shaft. The rotating support arm 203 and the sliding support arm 202 are respectively hinged to the connecting shaft.

[0041] The rubber wheel 201 is frustum-shaped, and the generatrix of the frustum of the rubber wheel 201 is tangent to the outer wall of the steel pipe being transported. This reduces friction with the steel pipe during transport, facilitating transport activities.

[0042] Combination Figure 3 , Figure 6 As shown, the reset assembly 400 includes a baffle 402 and a spring 401. One end of the spring 401 is fixed to the slide groove 205, and the other end is connected to the baffle 402. The baffle 402 abuts against the slider 204. The baffle 402 is set as a limiting mechanism, and the spring 401 is set on the baffle 402 to realize the reset of the sliding arm 202.

[0043] The bottom of the slider 204 is provided with a fixing groove. When the slider 204 is in the reset state, the position of the fixing groove corresponds to the position of the limiting through hole 206.

[0044] The limiting component 300 also includes a drive motor 301 and a drive gear 302. The limiting lifting mechanism includes a gear disk 303. The output end of the drive motor 301 is connected to the drive gear 302, and the drive gear 302 meshes with the gear disk 303. Two trapezoidal lifting adjustment blocks 304 are provided on the upper end surface of the gear disk 303 along the circumferential direction. One end of the limiting block 305 is disposed in the limiting through hole 206, and the other end abuts against the upper end surface of the gear disk 303.

[0045] The drive motor 301 drives the gear disk 303 to rotate, thereby causing the limit block 305 to move along the lifting adjustment block 304 on the upper end surface of the gear disk 303. When the limit block 305 is at the top of the lifting adjustment block 304, the limit block 305 passes through the limiting passage 206 and extends into the fixing groove at the bottom of the slider 204, blocking the movement of the slider 204; when the limit block 305 is at the bottom of the lifting adjustment block 304, the relative height of the limit block 305 decreases, leaving the fixing groove at the bottom of the slider 204, avoiding the movement of the slider 204.

[0046] Each set of transport guide wheel mechanism 200 has a gear disk 303 and a limiting block 305 at the bottom of the slide groove, and adjacent gear disks 303 are linked by bevel gears 306.

[0047] The ribbed steel pipe transport base also includes a proximity sensor 500, which is installed on the base body 100 near the incoming end of the transported steel pipe. The proximity sensor 500 monitors the position of the rib plate and sends a signal to control the drive motor 301 to drive the gear disk 303 to rotate, thereby causing the limit block 305 to disengage from the fixing groove at the bottom of the slider 204.

[0048] The reset assembly 400 also includes a Hall sensor 404 and a trigger head 403; the Hall sensor 404 is disposed at one end of the slide 205 away from the reset assembly 400, and the trigger head 403 is disposed on the opposite surface of the slide 204 and the Hall sensor 404.

[0049] When the rib passes the rubber wheel 201, the sliding arm 202 is rebounded back to its original position by the spring 401. The trigger head 403 on the slider 204 triggers the Hall sensor 404. The Hall sensor 404 sends a signal, which drives the motor 301 to drive the gear disk 303 to rotate, causing the limit block 305 to extend into the fixing groove at the bottom of the slider 204 for fixing.

[0050] In some embodiments, the slider 204 may be configured to have no fixed groove at the bottom. When the slider 204 is in the reset state, the slider 204 passes the position of the limiting through hole 206. When the limiting block 305 is at the top of the lifting adjustment block 304, the limiting block 305 passes through the limiting through hole 206 and is engaged with the rear end of the baffle 402, preventing the slider 204 from compressing the spring 401.

[0051] Combination Figures 7-9 As shown, during actual operation, the limiting block 305 inside the slide 205 is engaged with the slider 204 at the top of the lifting adjustment block 304, and the slider 204 cannot move forward inside the slide 205. The sliding support arm 202 and the rotating support arm 203 are in a stable state to support the movement of the ordinary section of the steel pipe.

[0052] When the proximity sensor 500 detects the rib approaching, it sends a signal. The drive motor receives the signal and begins to operate. The linkage gear disk 303 rotates clockwise by a certain angle, causing the limit block 305 to fall and leave the bottom fixing groove of the slider 204, thus avoiding the movement of the slider 204. At this time, the drive motor is not affected by the weight of the steel pipe, allowing the use of a large-volume steel pipe. The rib drives the rubber wheel 201 forward, compressing the spring 401 in the sliding arm 202. After the rib passes the rubber wheel 201, the sliding arm 202 is rebounded back to its original position by the spring 401. The trigger head 403 on the slider 204 triggers the Hall sensor 404, which sends a signal. After receiving the signal, the drive motor 301 rotates the gear disk 303 clockwise again, lifting the limit block 305 and fixing the sliding arm 202 until the next rib passes.

[0053] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
