Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted crane technology, and in particular to an adjustable anti-torsion vehicle-mounted crane. Background Technology

[0002] As a common loading and unloading equipment for small trucks, pickups, and other vehicles, truck-mounted cranes are usually directly fixed to the pre-set mounting holes in the truck bed with bolts to lift and transfer goods. For large truck beds, the fixed crane has a fixed lifting radius, which can only cover a part of the truck bed and cannot extend to other parts of the truck bed. The goods must be moved manually to the crane's coverage area, which not only increases labor intensity but also reduces work efficiency. Manually removing bolts to adjust the crane's position requires aligning the mounting holes and retightening the bolts multiple times, and the position remains fixed after adjustment, making it impossible to flexibly switch positions during operation.

[0026] Example 1 Reference Figures 1-3 and Figure 6This is the first embodiment of the present invention, which provides an adjustable anti-torsion vehicle-mounted crane. The adjustable anti-torsion vehicle-mounted crane includes a main body component 1, including a base plate 11. A bracket 12 is fixed on the base plate 11, and a rotating mechanism 13 is provided on the bracket 12. A mounting base 14 is fixed to the upper end of the rotating mechanism 13. A lever arm 15 is provided on the mounting base 14. The mounting base 14 has multiple insertion holes, and the lever arm 15 also has insertion holes. Pins are inserted into these holes to determine the angle between the lever arm 15 and the ground. One end of the lever arm 15 is... A telescopic boom 16 is provided, which can slide relative to the lever arm 15. The two are fixed by bolts, thereby adjusting the overall length of the boom. A hook 17 is provided below the telescopic boom 16, and a traction rope 18 is fixed to one side of the hook 17. A pulley 19 is provided at the end of the telescopic boom 16. The traction rope 18 passes around the pulley 19, and the other end is fixed to the winch 110. The winch 110 is fixed to the lever arm 15. The above components together constitute the crane. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0027] Auxiliary component 2, located on one side of the base plate 11, includes auxiliary component 21. By setting auxiliary component 21, the position of the crane in the larger truck bed can be flexibly adjusted, thereby expanding the lifting range.

[0028] The auxiliary component 21 includes a slide rail 211 located on one side of the base plate 11. The slide rail 211 can be fixed to the truck bed with bolts. A slide plate 212 is slidably arranged in the slide rail 211. The slide plate 212 has an installation groove 212-1. A rubber pad 213 is fixed to the inner wall of the installation groove 212-1. The rubber pad 213 has the characteristics of high hardness, high rigidity and low elastic deformation rate. It is not easy to deform under normal pressure. It only produces slight deformation when subjected to large pressure. A slider 214 is placed in the installation groove 212-1. The slider 214 can slide in the slide rail 211. The crane bolt is fixed to the slider 214. The movement of the slider 214 can drive the crane to move in the truck bed, thereby expanding the lifting range and improving loading efficiency.

[0029] Example 2 Reference Figures 3-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, the slide rail 211 has a first groove 211-1, the size of which corresponds to the slide plate 212. The slide rail 211 has a second groove 211-2, the size of which corresponds to the slider 214. A baffle 211-4 is provided at the end opening of the slide rail 211. When the slide plate 212 and the slider 214 are installed into the slide rail 211, they enter the interior from the opening of the slide rail 211. Then, the baffle 211-4 is fixed to the slide rail 211 by bolts.

[0031] The slide rail 211 can be configured according to the size of the truck bed and the crane. The slide rail 211 is U-shaped and divided into three sections to accommodate the loading process of larger truck beds.

[0032] Specifically, the slider 214 is connected to the base plate 11 by multiple bolts.

[0033] Specifically, the auxiliary component 2 also includes a locking member 22 located within the slider 214, which is configured to lock the position of the slider 214 within the slide rail 211.

[0034] The locking component 22 includes a locking block 221 that is slidably disposed within the slider 214. The locking block 221 is rectangular, and a corresponding locking groove 211-3 is provided on the slide rail 211. A first spring 222 is fixed to one side of the locking block 221, and the other end of the first spring 222 is fixed to the slider 214. The first spring 222 applies a continuous pushing force to the locking block 221 to ensure that the locking block 221 can engage with the locking groove 211-3. When the two engage, the position of the slider 214 within the slide rail 211 will be locked.

[0035] There are multiple locking grooves 211-3. Locking grooves 211-3 are provided at the ends and middle of the slide rail 211, and locking grooves 211-3 are also provided on the baffle 211-4.

[0036] Specifically, a pressing block 223 is slidably arranged inside the slider 214. There are multiple pressing blocks 223. One end of the pressing block 223 is fixed with a ring 224. The ring 224 connects multiple pressing blocks 223. When the ring 224 moves downward, it will drive all pressing blocks 223 to move downward synchronously. The pressing block 223 is used to release the locking block 221 from the locking groove 211-3, thereby releasing the slider 214 from the limit.

[0037] Example 3 Reference Figures 3-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0038] Specifically, a second spring 225 is fixed to one side of the ring 224, and the other end of the second spring 225 is fixed to the slider 214. The second spring 225 applies a continuous pushing force to the ring 224 to prevent the ring 224 and the pressing block 223 from moving downward under the action of gravity. The second spring 225 is also used for the reset of the two.

[0039] Specifically, one end of the pressing block 223 is inclined, and the locking block 221 has an inclined groove 221-1. As the pressing block 223 moves downward, its inclined surface can gradually fit into the inclined groove 221-1, thereby squeezing the inclined groove 221-1, which compresses the first spring 222 and drives the locking block 221 to move away from the locking groove 211-3. When the two are completely separated, the slider 214 contacts the limit and can slide in the slide rail 211.

[0040] Specifically, a pressing block 226 is fixed on the inner wall of the mounting groove 212-1. One end of the pressing block 226 is inclined. The pressing block 226 is set to apply a pushing force to the locking block 221, so that it is more tightly engaged with the locking groove 211-3.

[0041] When the crane is unloaded, the rubber pad 213 has not been compressed. At this time, the upper end of the compression block 226 is slightly lower than the lower end face of the locking block 221. When the crane starts lifting, the rubber pad 213 will deform under the weight of the cargo, causing the slider 214 to move downward as a whole, and driving the locking block 221 to move downward slightly. The compression block 226 moves upward relative to the locking block 221, so that the compression block 226 presses against the bottom end face of the locking block 221 at an angle, causing the locking block 221 to move closer to the locking groove 211-3, and the two engage more tightly, increasing the locking force.

[0042] When the position of the crane needs to be changed, the crane must be in an unloaded state. At this time, the rubber pad 213 will not be compressed, the compression block 226 will not contact the locking block 221, and thus will not affect the movement of the locking block 221.

[0043] Specifically, the size of the locking slot 211-3 is slightly larger than that of the locking block 221, so that the locking block 221 has room to move slightly downward.

[0044] Specifically, there are four locking blocks 221, and the number of pressing blocks 223 and squeezing blocks 226 are the same and correspond one-to-one. When the pressing ring 224 drives the four pressing blocks 223 to move synchronously, it will squeeze the four locking blocks 221 synchronously, so that the four locking blocks 221 are separated from the locking blocks 221.

[0045] In use, slide plate 212 and slider 214 are pushed into slide rail 211 from the opening of slide rail 211. Then, baffle 211-4 is fixed to slide rail 211 with bolts. Then, slide rail 211 is fixed in the truck bed with bolts, and slider 214 is bolted to bottom plate 11.

[0046] When the crane position needs to be changed, the crane is unloaded. Then, the squeezing ring 224 moves downward, causing all the pressing blocks 223 to move downward synchronously. The inclined surface of the pressing block 223 can gradually fit into the inclined groove 221-1, thereby squeezing the inclined groove 221-1. This causes the first spring 222 to be compressed, which in turn causes the locking block 221 to move away from the locking groove 211-3. When the two are completely separated, the slider 214 contacts the limit and can slide in the slide rail 211, releasing the ring 224. The second spring 225 drives the ring 224 and the pressing block 223 to reset. Before the lifting begins, the slider 214 needs to be pushed to confirm that the locking block 221 is engaged with the locking groove 211-3, ensuring that the position of the slider 214 is locked. This allows for flexible changes in the crane position to expand the lifting range and accommodate the loading and unloading of goods in large-sized truck beds.

[0047] After the hoisting begins, the rubber pad 213 will deform under the weight of the cargo, causing the slider 214 to move downward as a whole, and driving the locking block 221 to move slightly downward. The pressing block 226 moves upward relative to the locking block 221, causing the pressing block 226 to press against the bottom end face of the locking block 221 at an angle, causing the locking block 221 to move closer to the locking groove 211-3. The two engage more tightly, increasing the locking force and preventing the slider 214 from sliding or twisting along the slide rail 211.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
