Description

Technical Field

[0001] This utility model relates to the field of equipment transportation technology, and more specifically, to a tank-type transport vehicle adapted to rails. Background Technology

[0002] In the installation and transportation of large equipment such as ultra-high portal-type isolation doors in transonic wind tunnels, it is often necessary to move heavy-load, high-center-of-gravity, and flat-structured equipment along tracks to designated locations in confined spaces with no hoisting conditions. Due to the large size and uneven mass distribution of such equipment, and the complex scenarios involving track direction changes and multiple tooling connections during the transportation path, extremely high requirements are placed on the stability, guiding accuracy, and heavy-load adaptability of the transportation equipment.

[0003] In existing technologies, ground tank-type transport trolleys are typically used in conjunction with load-bearing fixtures to complete the transfer. However, traditional ground tank-type transport trolleys have many limitations in practical applications: First, the reliability of the track guidance is insufficient, and deviation is easily caused by uneven track or uneven thrust, which may even lead to the risk of overturning for equipment with a high center of gravity; Second, under heavy load, if the force distribution is uneven, a single wheel or a part of the wheel set is prone to overload, resulting in wheel wear or equipment vibration; Third, when multiple vehicles are driven in coordination, the synchronization of the driving force is poor, which may cause the tooling frame to twist, further aggravating the stress risk on the fixed structure of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a tank-type transport vehicle that is adapted to rails, which can solve the problems of track deviation and uneven force distribution in the existing technology, and ensure the safe and accurate transfer of heavy-load, high-center-of-gravity equipment.

[0005] The embodiments of this utility model are achieved through the following technical solutions: A rail-compatible tank-type transport vehicle includes a frame, the bottom of which is provided with a wheel assembly for supporting and traveling along the track; the front and rear ends of the frame are respectively provided with guide mechanisms for restricting the movement of the vehicle along the track direction; the top of the frame is provided with a load-bearing platform for carrying heavy-duty equipment, the load-bearing platform being elastically connected to the frame to adapt to load changes.

[0006] In some embodiments, the wheel assembly includes a plurality of wheels rotatably disposed on the inner side of the frame side plate, the wheels being arranged in a triangular pattern in the vertical direction to distribute the load; the outer side of the wheels is covered with an elastic layer.

[0007] In some embodiments, five wheels are arranged sequentially along the length of the frame, wherein the wheel axle height gradually decreases along both ends of the frame to accommodate track flatness errors, and its elastic deformation during frame weighing ensures that all wheels are always in contact with the top surface of the track.

[0008] In some embodiments, the guiding mechanism includes an elastic guide wheel and a lateral limiting plate; a fixing plate is fixedly connected to the lower outer side of the frame, and a mounting seat with its top slidably connected to the frame is provided on the inner side of the fixing plate. The outer side of the mounting seat is connected to the fixing plate by a spring, and an elastic guide wheel is rotatably connected inside the mounting seat. The elastic guide wheel abuts against both sides of the track; the lateral limiting plate is a rigid plate structure and is fixed to both sides of the frame and protrudes downwards from the track. The lateral limiting plate is distributed along the length of the frame and forms a limiting gap with the side of the track.

[0009] In some embodiments, the elastic guide wheels are provided with two sets located at the front and rear ends of the frame, respectively, and the lateral limiting plates are distributed along the length of the frame and cover the area between the elastic guide wheel sets on the same side of the frame.

[0010] In some embodiments, the load-bearing platform is connected to the vehicle frame roof plate by multiple sets of disc springs, which are distributed from the middle to the edge of the load-bearing platform. The disc springs located in the middle have a greater stiffness than the disc springs at the edge. The surface of the load-bearing platform is provided with anti-slip texture.

[0011] In some embodiments, a centralized drive adapter component is further included, which includes stroke synchronous telescopic cylinders located on both sides of the frame and extending along the length of the frame; the telescopic end of the stroke synchronous telescopic cylinder is detachably connected to the fixed end of the stroke synchronous telescopic cylinder of other transport trolleys.

[0012] In some embodiments, the frame is welded from high-strength alloy steel and has L-shaped reinforcing ribs on both sides. One side of the L-shaped reinforcing rib is connected to the top plate of the frame, and the other side is connected to the side plate of the frame.

[0013] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects: 1.

[0024] Please see Figures 1-5 As shown, the main body of this embodiment is a tank-type transport vehicle adapted to a track, including a frame 1. The bottom of the frame 1 is provided with a wheel assembly mechanism for supporting and traveling along the track. The front and rear ends of the frame 1 are respectively provided with guide mechanisms for restricting the movement of the vehicle along the track direction. The top of the frame 1 is provided with a load-bearing platform 2 for carrying heavy-duty equipment. The load-bearing platform 2 is elastically connected to the frame 1 to adapt to load changes.

[0025] Furthermore, the wheel assembly includes multiple wheels 3, which are rotatably disposed on the inner side of the side plate of the frame 1. The wheels 3 are arranged in a triangular pattern in the vertical direction to distribute the load. The outer side of the wheels 3 is covered with an elastic layer 4.

[0026] Furthermore, five wheels 3 are arranged sequentially along the length of the frame 1. The height of the wheel axle 5 of the wheel 3 gradually decreases along both ends of the frame 1 to accommodate the track flatness error. Its elastic deformation when the frame 1 is weighed ensures that all wheels 3 are always in contact with the top surface of the track.

[0027] Furthermore, the guiding mechanism includes an elastic guide wheel 7 and a lateral limiting plate 8; a fixing plate 12 is fixedly connected to the lower outer side of the frame 1, and a mounting seat 13 is provided on the inner side of the fixing plate 12, the top of which is slidably connected to the frame 1. The outer side of the mounting seat 13 is connected to the fixing plate 12 by a spring 6. An elastic guide wheel 7 is rotatably connected inside the mounting seat 13, and the elastic guide wheel 7 abuts against both sides of the track; the lateral limiting plate 8 is a rigid plate structure and is fixed to both sides of the frame 1 and protrudes downwards from the track. The lateral limiting plate 8 is distributed along the length direction of the frame 1 and forms a limiting gap with the side of the track.

[0028] Furthermore, the elastic guide wheel 7 is provided with two sets located at the front and rear ends of the frame 1, respectively, and the lateral limiting plate 8 is distributed along the length of the frame 1 and covers the area between the sets of elastic guide wheels 7 on the same side of the frame 1.

[0029] Furthermore, the load-bearing platform 2 is connected to the top plate of the frame 1 by multiple sets of disc springs 9. The disc springs 9 are distributed from the middle to the edge of the load-bearing platform 2, and the stiffness of the disc springs 9 located in the middle is greater than that of the disc springs 9 located at the edge. The surface of the load-bearing platform 2 is provided with anti-slip texture.

[0030] Furthermore, it also includes a centralized drive adapter component, which includes stroke synchronous telescopic cylinders 10 that are located on both sides of the frame 1 and extend along the length of the frame 1; the telescopic end of the stroke synchronous telescopic cylinder 10 is detachably connected to the fixed end of the stroke synchronous telescopic cylinder 10 of other transport trolleys.

[0031] Furthermore, the frame 1 is welded from high-strength alloy steel and has L-shaped reinforcing ribs on both sides. One side of the L-shaped reinforcing rib is connected to the top plate of the frame 1, and the other side is connected to the side plate of the frame 1.

[0032] This device addresses the technical problems of insufficient track guidance reliability and susceptibility to deviation in existing technologies through a dual-constraint design of the guiding mechanism. The guiding mechanism includes elastic guide wheels 7 and lateral limiting plates 8. The elastic guide wheels 7 are elastically connected to the frame 1 via springs 6, always abutting against both sides of the track, and using the preload of the springs 6 to correct minor deviations in real time. The lateral limiting plates 8 are distributed along the length of the frame 1 and form limiting gaps with the sides of the track, creating a rigid stop when the deviation exceeds the limit. The two work together to form a dual constraint, avoiding the risk of overturning caused by deviation in high-center-of-gravity equipment, and are particularly suitable for the precise guidance requirements of confined spaces such as wind tunnels and shelters.

[0033] In addition, five wheels 3 are arranged along the length of the frame 1 in this device, and the height of the axles 5 gradually decreases along both ends of the frame 1 (in a triangular distribution trend). Combined with the elastic deformation of the frame 1 under load, this ensures that all wheels 3 are always in contact with the top surface of the track, distributing the heavy load across multiple wheel sets and avoiding single-point overload. The outer side of the wheels 3 is wrapped with an elastic layer 4, which can further buffer impacts through its own deformation, reducing wheel wear and equipment vibration. Secondly, the load-bearing platform 2 is connected to the frame 1 via disc springs 9. The stiffness of the central disc spring 9 is greater than that of the edge springs, concentrating the load pressure towards the center while the edge springs 6 can adaptively adjust the local force, balancing the uneven load caused by uneven equipment mass, improving heavy-load stability, and thus solving the technical problem of uneven force distribution and easy overload of single wheels in existing transport trolleys under heavy load conditions.

[0034] Secondly, the frame 1 is welded with high-strength alloy steel, and the L-shaped reinforcing ribs 11 on both sides connect the top plate and the side plate to improve the overall structural rigidity and reduce deformation when connected with the tooling; the anti-slip texture on the surface of the bearing platform 2 enhances the friction with the tooling, avoids sudden changes in force caused by relative sliding, and ensures the accuracy of equipment docking.

[0035] In addition, the frame 1 is equipped with stroke synchronous telescopic cylinders 10 on both sides. The telescopic end of the cylinder is detachably connected to the fixed end of other transport trolleys. The mechanical rigidity constraint ensures that the driving speed of multiple vehicles is consistent, avoiding the twisting of the tooling frame caused by asynchronous driving force. It is especially suitable for multi-vehicle joint transfer scenarios of 200T heavy-duty equipment.

[0036] In summary, this device specifically addresses the core pain points of traditional tank-type transport vehicles in heavy-load, narrow-space, and high-precision transfer scenarios, meeting the safe transfer requirements of large industrial equipment.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
