Abstract
Description
Technical Field
[0001] This utility model relates to a hoisting device, specifically a simple hook assembly. Background Technology
[0002] Current transport vehicles, such as garbage trucks and sanitation vehicles, are loading and unloading trucks. The cargo compartment is controlled by a hydraulic mechanism, which can lift the front of the compartment and flip it over to facilitate unloading. However, these loading and unloading trucks cannot change the cargo compartment. Some users need to store different goods in different compartments, or they need to place the compartment in a designated location for use without parking the vehicle. Obviously, current loading and unloading trucks cannot meet these needs. Utility Model Content

[0005] Furthermore, the fixed frame is provided with guide pulleys arranged on the left and right sides at the rear end away from the flipping frame, and each guide pulley is provided with an annular retaining edge structure on its outer side.
[0006] Furthermore, guide plates arranged on the left and right are respectively provided at the rear end of the fixed frame away from the flipping frame, and the upper end of each guide plate extends outward at an upward angle.
[0007] Furthermore, the hook body of the hook structure is C-shaped, and the opening of the hook body faces forward.
[0008] Furthermore, the other end of the multi-stage telescopic cylinder is rotatably connected to the front crossbeam below the boom.
[0009] Furthermore, connecting rods are respectively provided in the fixed frame and the tilting frame, and the two ends of the tilting cylinder are respectively connected to the connecting rods in the fixed frame and the tilting frame through hinges.
[0010] Furthermore, it also includes a box body, with a handle on the top front side of the box body that hooks in conjunction with the hook structure, and rollers arranged on the left and right sides supporting the bottom rear side of the box body.
[0011] Furthermore, the tilting cylinder and the multi-stage telescopic cylinder are both set on the center line of the corresponding frame.
[0012] With the above design, this utility model facilitates the loading and unloading of the carriage. The entire carriage can be removed, allowing users to equip themselves with multiple interchangeable carriages to easily load different types of goods. In addition, it makes it easy to place the carriage in a designated location for use without having to park the vehicle at the same time, thus better meeting customer needs.

[0017] Figure 4 This is a front view structural diagram of the frame part of this utility model in the hoisting state. Detailed Implementation
[0018] like Figure 1-4 As shown, a simple hook assembly includes a fixed frame 1 and a tilting frame 2. The fixed frame 1 and the tilting frame 2 are rotatably connected by a rotating shaft 3. One end of the tilting cylinder 4 is rotatably connected to the fixed frame 1, and the other end of the tilting cylinder 4 is rotatably connected to the tilting frame 2. An arched boom 5 is vertically fixed to the other end of the tilting frame 2. A hook structure 6 is fixed to the top of the boom 5. The hook body of the hook structure 6 is C-shaped, and the opening of the hook body faces forward. A multi-stage telescopic cylinder 7 is rotatably installed inside the boom 5. The other end of the multi-stage telescopic cylinder 7 is rotatably connected to a fixed structure (such as the front crossbeam 10) below the boom 5. The tilting cylinder 4 and the multi-stage telescopic cylinder 7 are both set on the center line of the corresponding frame.
[0019] To ensure better positioning of the container 13 during hoisting and to improve the accuracy of loading and unloading the container 13, guide pulleys 8 are arranged on the left and right sides at the rear end of the fixed frame 1 away from the flipping frame 2, and annular retaining structures are provided on the outer side of each guide pulley 8. Guide plates 9 are arranged on the left and right sides at the rear end of the fixed frame 1 away from the flipping frame 2, and the upper end of each guide plate 9 extends outward at an upward angle. A good guiding structure can be formed through the guide pulleys 8 and guide plates 9 on each side.
[0020] Connecting rods 11 are respectively provided in the fixed frame 1 and the flipping frame 2. The two ends of the flipping cylinder 4 are rotatably connected to the connecting rods 11 in the fixed frame 1 and the flipping frame 2 through hinges 12.
[0021] It also includes a box body 13, with a handle 14 on the top front side of the box body 13 that hooks in conjunction with the hook structure 6, and rollers 15 arranged on the left and right sides supporting the bottom rear side of the box body 13.
[0022] The working principle of this utility model is as follows: When hoisting the box body 13, the frame part is in... Figure 4 In this state, the hook structure 6 is tilted downwards. In coordination with vehicle movement, the hook body of the hook structure 6 aligns with the handle 14, and the hook structure 6 is engaged with the handle 14. At this time, the tilting cylinder 4 extends, and the multi-stage telescopic cylinder 7 retracts. Under the push of each cylinder, the tilting frame 2 slowly tilts back (forward) along the rotating shaft 3, thereby driving the box body 13 to move obliquely upwards. The bottom of the box body 13 contacts the guide pulley 8 of the fixed frame 1 and moves along the guide pulley 8 and guide plate 9. Finally, when the fixed frame 1 and the tilting frame 2 are in the same plane, the box body 13 is hoisted into place. When unloading the box body 13, the operation is the reverse of the above process. Since the hook body of the hook structure 6 is C-shaped, when the handle 14 is pushed outwards, the inner end of the hook structure 6 can also generate thrust, making it easy to unload the box body 13.
[0023] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
