The superior torsional resistance of the limiting plates improves the limiting stability of the second limiting mechanism, and the rolling contact of the limiting wheels prevents direct contact between the limiting plates and the wheels during transportation, thus avoiding excessive friction and wheel damage.

Description

Technical Field

[0001] This utility model relates to the field of hoisting and transfer frames, specifically a hoisting and transfer frame for small vehicles. Background Technology

[0002] After the sanitation vehicles are assembled in the production workshop, they need to be hoisted onto flatbed trucks using a transfer frame for transportation. Specifically, the sanitation vehicle is driven, aligned, and moved onto the transfer frame. The front and rear wheels of the vehicle are limited by baffles or blocks on the front and rear sides of the transfer frame. Then, the transfer frame is connected by a hoisting rope, thereby hoisting the sanitation vehicle and the transfer frame together onto the flatbed truck for transportation. During transportation, the transfer frame restricts the movement of the sanitation vehicle.

[0003] In existing technologies, in addition to using baffles or blocks to limit the front and rear of vehicle wheels, there is also the practice of using ropes to bind the vehicle wheels to the transfer frame. This is to prevent the wheels from bouncing during transportation when the flatbed truck experiences sudden braking, sharp turns, or bumps, which could lead to a collision between the sanitation vehicle and the flatbed truck, or the wheels from dislodging from the baffles or blocks and falling off. However, the binding with ropes is highly unstable. When the wheels tend to bounce or shift, the ropes are easily slipped due to excessive twisting. Even if the ropes cross the top of the wheels and connect to the transfer frame, the wheels still have the risk of lateral deviation and swaying. Furthermore, excessively tight binding can wear down the wheel surface, affecting the quality of the new vehicle.

[0004] The research objective of this utility model is to design a hoisting and transfer frame for small vehicles to address the problems existing in the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a hoisting and transfer frame for small vehicles, which can effectively solve the problems existing in the prior art.

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

[0007] A lifting and transfer frame for small vehicles, comprising:

[0008] The frame is used to support the corresponding vehicles and to be lifted by the corresponding lifting mechanism.

[0009] A first limiting mechanism is provided on the frame and is used to limit the front and rear sides of several wheels of the vehicle.

[0010] The second limiting mechanism includes several limiting plates that are respectively used to cover the upper part of several wheels and whose two ends are respectively detachably connected to the frame, and several limiting wheels that are rotatably mounted on the limiting plates and used to roll against the wheels.

[0011] Furthermore, the width of the limiting plate is at least greater than half the thickness of the wheel, the middle part of the limiting plate is arc-shaped and corresponds to the limiting part of the upper half of the wheel, and a plurality of the limiting wheels rotate back and forth through the inner side of the limiting part and are used to roll against the upper half of the wheel.

[0012] Furthermore, the inner side of the limiting part is recessed with a plurality of limiting grooves, and the inner walls of the two sides of the limiting grooves are respectively embedded with deformable flexible sleeves. The limiting wheel is rotatably disposed in the limiting groove via a rotating shaft, and the two ends of the rotating shaft are rotatably sleeved with the flexible sleeves. The bottom of the plurality of limiting grooves is provided with a rough layer that is spaced apart from the limiting wheel. When the limiting wheel is pressed against the rough layer by the wheel pressure, the flexible sleeve deforms and the limiting wheel is restricted from rotating by the friction of the rough layer.

[0013] Furthermore, the two ends of the limiting plate first extend vertically downward to form a connecting part, and then fold in the opposite direction to form a connecting part that is horizontally arranged and used to screw the frame. An installation area is formed between the two connecting parts and the corresponding wheels. The first limiting mechanism includes a front limiting member and a rear limiting member respectively installed in the installation area.

[0014] Furthermore, the wheel includes two front wheels and two rear wheels. The front limiting member includes a stop block fixed to the front side of the front wheel. The rear side of the stop block forms a limiting surface that is adapted to the arc shape of the front side of the front wheel. The rear limiting member includes several fixing blocks fixed to the frame and a limiting tube corresponding to the rear side of the rear wheel, which is laterally screwed to several of the fixing blocks by bolts. The distance between the limiting tube and the limiting surface is adjusted by the screwing depth of the bolts.

[0015] Furthermore, the frame includes two side-by-side support frames extending forward and backward, several connecting frames connecting the two support frames, and a guide frame connecting the rear ends of the two support frames and inclined to the ground. The top of the support frame is fixed with several support plates with front-to-back spacing, several thickened plates for screwing the connecting parts and thickening them, and anti-slip plates corresponding to the bottom of several wheels and having anti-slip patterns. The bottom of the support frame is fixed with several support feet and lifting pipes corresponding to the front and rear sides of several wheels and for allowing the lifting rope to pass through.

[0016] Therefore, the beneficial effects of this utility model are:

[0017] 1. By replacing the existing binding ropes with limiting plates, the vehicle is not only limited in front and rear by the first limiting mechanism when on the frame, but its wheels are also limited and covered by several limiting plates. This not only avoids the risk of the wheels jumping and colliding with the flatbed truck during sudden braking, sharp turns, and bumps in flatbed transportation, but also prevents the wheels from dislodging or falling off due to the first limiting mechanism. Furthermore, the superior torsional resistance of the limiting plates prevents them from excessively twisting and slipping when the wheels tend to jump or shift. This ensures that the limiting plates are always limited and covered on the outside of the wheels, improving the limiting stability of the second limiting mechanism. At the same time, the addition of several limiting wheels prevents the limiting plates from directly contacting the wheels, instead using the rolling of these wheels to abut against the wheels. This avoids direct contact between the limiting plates and the wheels during transportation, preventing excessive friction and wheel damage. In addition, the limiting plates can be fully pre-tensioned without worrying about wheel wear, further improving the limiting stability of the limiting plates.

[0018] 2. By limiting the width, the limiting plate has sufficient width to cover the upper part of the wheel and has sufficient anti-torsional performance, further improving the limiting effect of the limiting plate. At the same time, the limiting wheel is set to rotate back and forth, thereby avoiding lateral displacement between the limiting plate and the wheel and improving the stability of the limiting plate in limiting the wheel.

[0019] 3. By adding a flexible sleeve and a rough layer, the limiting wheel abuts against the wheel and the wheel has a large displacement tendency to jump or move back and forth. When the limiting wheel is pressed against the rough layer by the wheel pressure, the corresponding flexible sleeve will deform and the limiting wheel will be restricted from rotating by the friction of the rough layer. This is to avoid the limiting wheel rolling freely when the wheel has a large displacement tendency, making it difficult to effectively limit the displacement of the wheel, which would cause the wheel to slip and shake continuously in the limiting plate and be damaged. The friction restriction of the rough layer changes the rolling abutment limit of the limiting roller to a fixed abutment limit, improves the limiting effect of the limiting wheel, thereby improving the overall limiting effect of the limiting plate and reducing the displacement tendency of the wheel.

[0020] 4. The vertically set connecting part forms an installation area between the wheel and the installation area, which not only reduces the front and rear space occupied by the limiting plate, but also allows the ceremonial limiting mechanism to be installed in the installation area. This improves the structural compactness between the first limiting mechanism and the second limiting mechanism without interfering with each other. In this way, it can not only improve the limiting effect on the wheel, but also shorten the front and rear length of the frame and reduce hoisting and transportation costs.

[0021] 5. The distance between the limiting tube and the limiting surface is adjusted by the bolt threading depth, so that the distance between the limiting tube and the limiting surface can be adaptively adjusted according to the distance between the front wheel and the rear wheel, improving the limiting adaptability of the first limiting mechanism, and ensuring that the limiting tube can be stably abutted against the rear side of the rear wheel by the bolt threading depth control, and that there will be no situation where the gap is too large and the wheel will be displaced.

[0026] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0027] refer to Figure 1-4 A lifting and transfer frame for small vehicles, used for lifting and transferring small sanitation vehicles, comprising:

[0028] Frame 1 is used to support the corresponding vehicle and to be lifted by the corresponding lifting mechanism;

[0029] The first limiting mechanism is provided on the frame 1 and is used to limit the front and rear sides of several wheels of the vehicle.

[0030] The second limiting mechanism includes several limiting plates 2, which are respectively used to cover the upper part of several wheels and are detachably connected to the frame 1 at both ends, and several limiting wheels 21, which are rotatably mounted on the limiting plates 2 and used to roll against the wheels.

[0031] The aforementioned structure replaces the existing binding ropes with limiting plates 2, ensuring that when the vehicle is on the frame 1, it is not only limited in front and rear by the first limiting mechanism, but its wheels are also limited and covered by several limiting plates 2. This not only avoids the risk of the wheels jumping and colliding with the flatbed truck during sudden braking, sharp turns, or bumps during flatbed truck transportation, but also prevents the wheels from dislodging or falling off due to the first limiting mechanism. Furthermore, the superior torsional resistance of the limiting plates 2 prevents them from excessively twisting and slipping off when the wheels tend to jump or shift. This ensures that the limiting plates 2 are always limited and covered on the outside of the wheels, improving the limiting stability of the second limiting mechanism. At the same time, the addition of several limiting wheels 21 prevents the limiting plates 2 from directly contacting the wheels, but rather the limiting plates 2 roll against the wheels, thus avoiding excessive friction between the limiting plates 2 and the wheels during transportation and preventing wheel damage. Based on this, the limiting plates 2 can be fully pre-tightened without worrying about wheel wear, thereby further improving the limiting stability of the limiting plates 2.

[0032] To improve the limiting effect of the limiting plate 2, the width of the limiting plate 2 is at least half the thickness of the wheel. The middle part of the limiting plate 2 is arc-shaped and corresponds to the limiting part 22 of the upper half of the wheel. A plurality of limiting wheels 21 rotate back and forth, passing through the inner side of the limiting part 22 and rolling against the upper half of the wheel. Thus, by limiting the width, the limiting plate 2 has sufficient width to cover the upper half of the wheel and has sufficient torsional resistance, further improving the limiting effect of the limiting plate 2. At the same time, by setting the limiting wheels 21 to rotate back and forth, the lateral relative displacement between the limiting plate 2 and the wheel is avoided, improving the stability of the limiting plate 2 in limiting the wheel.

[0033] To improve the limiting effect of the limiting wheel 21, the inner side of the limiting part 22 is recessed with several limiting grooves 221. Deformable flexible sleeves 222 are embedded in the inner walls of both sides of each limiting groove 221. The limiting wheel 21 is rotatably mounted within the limiting grooves 221 via a rotating shaft 211. The two ends of the rotating shaft 211 are rotatably fitted with the flexible sleeves 222. A rough layer 223 is provided at the bottom of each limiting groove 221, with a gap between the groove and the limiting wheel 21. Through the addition of the flexible sleeves 222 and the rough layer 223, the limiting wheel 21 abuts against the wheel, and the wheel exhibits a greater tendency to jump or move back and forth. When the limiting wheel 21 is pressed against the rough layer 223 by the wheel pressure, the corresponding flexible sleeve 222 will deform and the limiting wheel 21 will be restricted from rotating by the friction of the rough layer 223. This is to prevent the limiting wheel 21 from rolling freely when the wheel has a large displacement tendency, making it difficult to effectively limit the displacement of the wheel, which would cause the wheel to slip and shake continuously in the limiting plate 2 and be damaged. By limiting the friction of the rough layer 223, the rolling contact limiting of the limiting wheel is changed to fixed contact limiting, improving the limiting effect of the limiting wheel 21, thereby improving the overall limiting effect of the limiting plate 2 and reducing the displacement tendency of the wheel.

[0034] To improve the structural compactness of the first and second limiting mechanisms, the two ends of the limiting plate 2 first extend vertically downward to form connecting portions 23, and then fold in the opposite direction to form connecting portions 24 arranged laterally for screwing onto the frame 1. An installation area 3 is formed between the two connecting portions 23 and the corresponding wheels. The first limiting mechanism includes a front limiting member 4 and a rear limiting member 5 respectively installed in the installation area 3. This structure, by forming the installation area 3 between the vertically arranged connecting portions 23 and the wheels, not only reduces the front and rear space occupied by the limiting plate 2, but also allows the ceremonial limiting mechanism to be accommodated and installed within the installation area 3. This improves the structural compactness of the first and second limiting mechanisms without interfering with each other, thereby not only improving the wheel restriction effect but also shortening the front and rear length of the frame 1, reducing hoisting and transportation costs.

[0035] To improve the limiting adaptability of the first limiting mechanism, the wheel includes two front wheels 6 and two rear wheels 7. The front limiting member 4 includes a stop block fixed to the front side of the front wheel 6. The rear side of the stop block forms a limiting surface 41 that is adapted to the arc shape of the front side of the front wheel 6. The rear limiting member 5 includes several fixing blocks 51 fixed to the frame 1 and a limiting tube 52 corresponding to the rear side of the rear wheel 7, which is laterally screwed to several fixing blocks 51 by bolts 53. The distance between the limiting tube 52 and the limiting surface 41 is adjusted by the screwing depth of the bolts 53, so that the distance between the limiting tube 52 and the limiting surface 41 can be adaptively adjusted according to the distance between the front wheel 6 and the rear wheel 7, thereby improving the limiting adaptability of the first limiting mechanism. It can also ensure that the limiting tube 52 can be stably abutted against the rear side of the rear wheel 7 by the screwing depth of the bolts 53, and there will be no situation where the gap is too large and the wheel will shift.

[0036] To improve the practicality of the frame 1, the frame 1 includes two side-by-side support frames 11 extending forward and backward, several connecting frames 12 connecting the two support frames 11, and a guide frame 13 connecting the rear ends of the two support frames 11 and inclined to the ground. The top of the support frame 11 is fixed with several support plates 111 with front-to-back spacing, several thickened plates 112 for screwing the connecting part 24 and being thickened, and anti-slip plates 113 corresponding to the bottom of several wheels and having anti-slip textures. The bottom of the support frame 11 is fixed with several support feet 114 and lifting pipes 115 corresponding to the front and rear sides of several wheels and for allowing the lifting rope to pass through. The thickened plate 112 improves the stability of the connection between the limiting plate 2 and the frame 1. The anti-slip plate 113 improves the stability of the vehicle after it is driven onto the support frame 11 via the guide frame 13, thereby enhancing the safety of the first and second limiting mechanisms. By placing the lifting pipe 115 on the front and rear sides of several wheels, the overall center of gravity balance of the vehicle and the frame 1 is improved during lifting, thus enhancing lifting stability. Therefore, the above structures together improve the practicality of the frame 1.

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.
