Technical Field
[0001] The utility model belongs to the technical field of cargo loading and unloading devices, and in particular relates to a vehicle-mounted cargo loading and unloading device. Background Art
[0002] A pickup truck is a vehicle that has a sedan front and cab, but also an open compartment. It has high driving comfort and power, and good cargo capacity. Pickup trucks have a variety of uses. They can be used as special-purpose vehicles, multi-purpose vehicles, official vehicles, business vehicles, or as family vehicles for carrying cargo, traveling, etc.
[0003] However, due to the considerations of the vehicle model and driving comfort, the cargo bed of pickup trucks does not have a lifting function. When using pickup trucks to transport goods, both loading and unloading are done manually. This is especially true when transporting large and heavy materials, which is extremely time-consuming and labor-intensive to lift up and down manually. It also consumes a lot of workers' physical energy and is prone to safety accidents during the loading and unloading process.
[0004] To this end, we propose a vehicle-mounted cargo loading and unloading device that can be installed on a pickup truck or other vehicle type with a hopper. Utility Model Content
[0005] The purpose of the utility model is to provide a vehicle-mounted cargo loading and unloading device to solve the problem in the prior art that, since the cargo boxes of pickup trucks and similar small cargo vehicles do not have a lifting function, loading and unloading of cargo during transportation is extremely time-consuming and labor-intensive, and safety accidents are prone to occur during the loading and unloading process.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A vehicle-mounted cargo loading and unloading device comprises two sets of folding arms, which are respectively fixedly mounted on the top ends of the side plates on both sides of the vehicle cargo box. The folding arms and the top ends of the side plates of the cargo box can be assembled by welding or by using bolts according to the needs. The front ends of the two sets of folding arms are welded with transverse bending beams, and the middle part of the transverse bending beams is installed with an electric hoist with a built-in controller. The setting of the transverse bending beams, on the one hand, is to connect the folding ends of the two sets of folding arms to achieve synchronous fixation, and on the other hand, is to cooperate with the electric hoist to play a role in lifting and bearing the load of cargo.
[0008] Furthermore, the two groups of folding arms have the same structure, and the folding arms include a mounting groove, and the tail end of the mounting groove is rotatably mounted with a sub-arm through a pin shaft, and the outside of the pin shaft located on the inner side of the mounting groove is provided with a spacer sleeve for positioning the tail end structure of the mounting groove to prevent the connection position between the tail end of the mounting groove and the sub-arm from deforming inwardly under the action of external force, thereby achieving the purpose of improving the connection stability between the mounting groove and the sub-arm.
[0009] Furthermore, in order to enable the folding arm to cooperate with the electric hoist and have the ability to load, unload and move goods, a telescopic cylinder is installed between the mounting slot and the auxiliary arm through a rotating shaft, the length of the auxiliary arm is adapted to the length of the mounting slot, and the maximum flipping angle between the auxiliary arm and the mounting slot is 125-135 degrees.
[0010] Furthermore, in order to reduce the size of the folding arm after being folded and closed, the space can be fully utilized while improving the load-bearing capacity of the folding arm, so as to increase the weight limit of the device when lifting goods, the mounting groove and the auxiliary arm are both U-shaped channel steels, the mounting groove and the auxiliary arm are relatively designed, and the auxiliary arm is buckled on the outside of the mounting groove, and the tail ends of the auxiliary arm and the mounting arm are both semicircular structure designs. The semicircular design of the mounting groove and the tail end of the auxiliary arm is mainly for the convenience of flipping the auxiliary arm at the tail end of the mounting groove with the pin shaft as the center of the circle.
[0011] Furthermore, since a snap-fit design is adopted between the mounting groove and the auxiliary arm, and the front end of the telescopic cylinder and the auxiliary arm are hingedly assembled using a transverse rotating shaft, in order to avoid movement interference when the auxiliary arm and the mounting groove are fully closed, an avoidance groove is opened in the middle of the mounting groove, and the avoidance groove is either U-shaped or V-shaped.
[0012] Furthermore, in order to realize the detachable assembly between the folding arm and the side plate of the truck bed, threaded holes for installing bolts are provided at equal distances at the bottom of the installation groove.
[0013] Furthermore, in order to improve the stability of the folding arm and the side plate of the vehicle bucket during assembly, groove edges are provided on both sides of the bottom of the mounting groove.
[0014] Furthermore, in order to improve the stability of the installation slot and the auxiliary arm after they are fully closed and minimize the left and right shaking of the auxiliary arm, a positioning pile is vertically welded on the inner side of the front end of the installation slot, and a positioning sleeve is welded on the inner side of the front end of the auxiliary arm at the position corresponding to the positioning pile.
[0015] Furthermore, a positioning bend groove is welded on the front end of the auxiliary arm. The positioning bend groove is mainly set to further improve the stability of the two groups of folding arms after they are closed by snapping together with the two sides of the front guardrail of the vehicle bucket after the auxiliary arm and the mounting groove are completely closed. A placement box is installed at the front end of the auxiliary arm of one group of folding arms. The placement box comes with a box cover, and a wire avoidance groove is provided on the side of the box body to facilitate the storage of the controller.
[0016] Furthermore, in order to improve the load-bearing capacity of the entire transverse curved beam, support arms are welded between the two ends of the transverse curved beam and the auxiliary arms.
[0017] Beneficial effects:
[0018] The utility model uses two sets of folding arms as a basis, which are installed on the top of the side panels on both sides of the truck bed, and then combined with the transverse curved beams installed at the front ends of the two sets of folding arms and the electric hoist to realize the loading and unloading operations of goods. The entire cargo loading and unloading process does not require manual lifting of the goods, which saves time and effort, and is safer than traditional pure manual loading and unloading. In addition, the design structure of the utility model is simple, does not occupy the truck bed space, is highly practical, and is easy to operate, which can make the loading and unloading operations when the vehicle transports goods simpler and more effective, and a single person can realize the loading and unloading of heavy objects.

DETAILED DESCRIPTION
[0024] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model.

It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.
[0025] Example
[0026] For pickup trucks and similar vehicles with hoppers, since the bucket does not have a lifting function, during the cargo transportation process, both loading and unloading are done by manual handling. Especially in the process of transporting some large and heavy goods, it is extremely time-consuming and labor-intensive to lift them up and down manually, which consumes a lot of workers' physical strength, and safety accidents are prone to occur during the loading and unloading process. At the same time, when encountering such large-scale transportation, a single person is completely unable to complete the loading and unloading operations alone, and at least two people are required to cooperate in the operation, which is extremely inconvenient in some special cargo transportation scenarios.
[0027] like Figure 1 , Figure 2 As shown, this embodiment provides a vehicle-mounted cargo loading and unloading device, which specifically includes two groups of folding arms, and the two groups of folding arms are respectively fixedly mounted on the top of the side panels on both sides of the vehicle cargo box. The assembly method between the folding arms and the top of the side panels of the cargo box can be welded or fixed by bolts according to needs. A transverse bending beam 8 is welded at the front end of the two groups of folding arms, and an electric hoist 9 with a built-in controller 11 is installed in the middle of the transverse bending beam 8. Among them, the setting of the transverse bending beam 8, on the one hand, is to connect the folding ends of the two groups of folding arms to achieve synchronous fixation, and on the other hand, it is used to cooperate with the electric hoist 9 to play a role in lifting and bearing the load of cargo.
[0028] Further, such as Figure 1 , Figure 2 , Figure 3 As shown, the two groups of folding arms have the same structure, and each group of folding arms includes a mounting groove 1 for fixed assembly with the side plate of the truck bed, wherein the rear end of the mounting groove 1 is rotatably mounted with a secondary arm 3 through a pin shaft 2, and the pin shaft 2 located on the inner part of the mounting groove 1 is sleeved with a spacer sleeve on the outside, which is used to position the rear end structure of the mounting groove 1 to prevent the connection position between the rear end of the mounting groove 1 and the secondary arm 3 from deforming inwards under the action of external force, thereby achieving the purpose of improving the connection stability between the mounting groove 1 and the secondary arm 3.
[0029] like Figure 1 , Figure 2 As shown, in order to enable the folding arm to cooperate with the electric hoist 9 and have the ability to load, unload and move goods, a telescopic cylinder 5 is installed between the mounting slot 1 and the auxiliary arm 3 through the rotating shaft 4. The telescopic cylinder 5 is preferably a long-arm hydraulic cylinder. The length of the auxiliary arm 3 is adapted to the length of the mounting slot 1, and the maximum flipping angle between the auxiliary arm 3 and the mounting slot 1 is 125-135 degrees.
[0030] It needs to be further explained that the length of the auxiliary arm 3, the length of the mounting groove 1, and the length of the transverse bending beam 8 can all be customized according to the size of the vehicle cargo box, so as to achieve the purpose of adapting to the cargo boxes of different types of vehicles, and the hydraulic end of the telescopic cylinder 5 needs to be connected to the hydraulic equipment installed on the vehicle.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in order to reduce the size of the folding arm after folding and closing, make full use of the space and improve the load-bearing capacity of the folding arm, so as to increase the weight limit of the device when lifting goods, the mounting groove 1 and the auxiliary arm 3 are both U-shaped channel steels, the mounting groove 1 and the auxiliary arm 3 are relatively designed, and the auxiliary arm 3 is buckled on the outside of the mounting groove 1, and the tail ends of the auxiliary arm 3 and the mounting arm are both semicircular in structure. The semicircular design of the mounting groove 1 and the tail end of the auxiliary arm 3 is mainly for the convenience of flipping the auxiliary arm 3 at the tail end of the mounting groove 1 with the pin shaft 2 as the center.
[0032] Further, such as Figure 1 , Figure 2 As shown, since a snap-fit design is adopted between the mounting slot 1 and the auxiliary arm 3, and the front end of the telescopic cylinder 5 and the auxiliary arm 3 are hingedly assembled by using a transverse rotating shaft 4, in order to avoid movement interference when the auxiliary arm 3 and the mounting slot 1 are fully closed, an avoidance groove 6 is opened in the middle of the mounting slot 1, and the avoidance groove 6 is either U-shaped or V-shaped. It should be further explained that after the mounting slot 1 and the auxiliary arm 3 are fully closed, the telescopic cylinder 5 is in a retracted state, and an inclination angle of 3-5 degrees is formed between the telescopic cylinder 5 as a whole and the bottom of the mounting slot 1, so that the telescopic cylinder 5 can smoothly push the auxiliary arm 3 to fully unfold when extending.
[0033] Furthermore, in order to realize the detachable assembly between the folding arm and the side plate of the truck bed, threaded holes for installing bolts are provided at equal distances at the bottom of the installation groove 1 .
[0034] Further, such as Figure 3 As shown, in order to improve the stability of the folding arm and the side plate of the vehicle bucket during assembly, groove edges 15 are further provided on both sides of the bottom of the installation groove 1.
[0035] Further, such as Figure 2 , Figure 3 As shown, in order to improve the stability of the mounting groove 1 and the auxiliary arm 3 after they are fully closed and minimize the left and right shaking of the auxiliary arm 3, a positioning pile 13 is vertically welded on the inner side of the front end of the mounting groove 1, and a positioning sleeve 14 is welded on the inner side of the front end of the auxiliary arm 3 at a position corresponding to the positioning pile 13. When the mounting groove 1 and the auxiliary arm 3 are fully closed, the positioning pile 13 is inserted into the positioning sleeve 14, and cooperates with the pin shaft 2 to form front and rear limit for the mounting groove 1 and the auxiliary arm 3.
[0036] Further, such as Figure 1 , Figure 2 , Figure 4As shown, a positioning bend groove 7 is welded at the front end of the auxiliary arm 3. The positioning bend groove 7 is mainly provided so that after the auxiliary arm 3 and the mounting groove 1 are completely closed, the positioning bend groove 7 can be snap-fitted with both sides of the guardrail at the front end of the vehicle bucket to further improve the stability of the two sets of folding arms after closing.
[0037] In order to conveniently place the controller 11 of the electric hoist 9, a placement box 12 is installed at the front end of the auxiliary arm 3 of a group of folding arms. The placement box 12 has a box cover and a wire avoidance groove is provided on the side of the box body to facilitate the storage of the controller 11.
[0038] Further, such as Figure 1 , Figure 2 As shown, in order to improve the load-bearing capacity of the entire transverse curved beam 8, support arms 10 are welded between the two ends of the transverse curved beam 8 and the auxiliary arm 3.
[0039] During the use of the entire cargo loading and unloading device, the extension and contraction of the telescopic cylinder 5 controls the expansion and folding of the folding arm. As the folding arm is expanded and folded, the electric hoist 9 is lifted and moved. When the folding arm is fully expanded, the electric hoist 9 moves to the outside of the rear end of the truck bed as the auxiliary arm 3 is fully expanded. At this time, the lifting rope is used to fix the cargo, and the electric hoist 9 is controlled to reel in and lift the cargo. Then the telescopic cylinder 5 is controlled to contract, so that the cargo moves toward the inside of the truck bed, thereby achieving the purpose of loading. The same applies to unloading.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
