Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary devices for garbage trucks, and in particular, auxiliary devices for lifting garbage bins. Background Technology

[0002] Garbage trucks are mainly used to transport various types of garbage, and are suitable for transporting household waste in residential areas. They can compress and crush the garbage, increasing its density and reducing its volume, which greatly improves the efficiency of garbage collection and transportation. Before compressing the garbage, the garbage truck needs to lift the garbage bin to the predetermined position using a lifting device and dump the garbage into the garbage truck. However, most existing garbage bin lifting devices only fix the garbage bin with claws or clamps. This fixing method will cause the sides of the garbage bin to be subjected to a large pulling force when the garbage bin is dumped, which will eventually lead to damage to the garbage bin.

[0003] A search revealed a Chinese patent document (authorization announcement number CN209889575U) regarding a garbage truck bin lifting device. This device includes a connecting frame, a horizontal plate fixedly mounted on the surface of the connecting frame, a claw fixedly mounted on the side of the horizontal plate away from the connecting frame, a stop block fixedly mounted on the top of the connecting frame, and a bearing fixedly mounted on the connecting frame. This structure uses the claw and clamping frame to limit the position of the garbage bin, thereby improving its stability. However, this device experiences significant pulling force on the claw when the garbage bin is tilted, and since most garbage bins are made of plastic, prolonged use can directly damage the bin. Therefore, a garbage bin lifting auxiliary device is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a trash can lifting auxiliary device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a trash can lifting auxiliary device, including a vertical rod for installing the trash can lifting device and a sliding rod for moving the lifting device. A vertical plate is fixedly installed on the side wall of the sliding rod. Two vertical grooves are symmetrically opened longitudinally on the side wall of the vertical plate, and rectangular blocks are slidably installed in the vertical grooves. An installation plate is fixedly installed on the side wall of the two rectangular blocks, and a bottom plate is horizontally fixedly installed on the bottom of the side wall of the installation plate.

[0006] Two L-shaped rods are symmetrically fixedly installed on the side wall of the vertical plate;

[0007] Two hydraulic cylinders are symmetrically fixedly installed on the side of the vertical plate away from the mounting plate. A connecting plate is fixedly installed on the side of the mounting plate away from the base plate. The telescopic ends of the hydraulic cylinders are fixedly connected to the connecting plate.

[0008] The mounting plate has two symmetrically formed grooves on its side wall, and a slider is slidably installed in the groove. A horizontal plate is fixedly installed between the two sliders, and a claw is fixedly installed on the side wall of the horizontal plate.

[0009] Preferably, a spring is fixedly installed at the lower end of the inner side of the slide, and the upper end of the spring is fixedly connected to the bottom of the slider.

[0010] Preferably, a limit rod is fixedly installed longitudinally inside the slide groove, and a limit hole is formed through the side wall of the slider.

[0011] Preferably, the limiting rod slides through the limiting hole opened in the side wall of the slider.

[0012] Preferably, the top surface of the base plate is provided with multiple arc-shaped grooves, and ball bearings are rolled and installed in the arc-shaped grooves.

[0013] Preferably, one side of the top surface of the base plate is inclined, and multiple strip grooves are horizontally formed on the inclined surface of the base plate.

[0014] Preferably, traction rollers are rotatably mounted inside each of the plurality of said strip grooves.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This trash can lifting auxiliary device, thanks to the installation plate, base plate, traction rollers and ball bearings, pushes the trash can towards the base plate. At this time, the trash can is pulled by multiple traction rollers and the inclined surface of the base plate, and at the same time, the trash can is easily pushed to the top surface of the base plate by the action of multiple ball bearings.

[0017] This trash can lifting auxiliary device, thanks to the setting of two L-shaped rods and two hydraulic cylinders, activates the two hydraulic cylinders when the trash can moves to the bottom plate, driving the mounting plate and the bottom plate to move upward until the two L-shaped rods are inserted into the inside of the trash can, limiting the trash can;

[0018] This trash can lifting auxiliary device benefits from the design of a chute, slider, horizontal plate, claws, and springs. When the trash can is pushed to the bottom plate, the horizontal plate is first pressed down. When the trash can is pushed to the bottom plate, the horizontal plate is released, causing the spring to lose its downward pressure and extend upward. The spring will push the slider, horizontal plate, and claws upward, so that the claws can engage with the grooves on the edge of the trash can.

[0019] Compared with existing technologies, this trash can lifting aid device facilitates the movement of the trash can while further improving the stability of the trash can when it is tilted. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 4The main structure of the garbage bin lifting auxiliary device shown is a vertical rod 1 for installing the garbage bin lifting device and a sliding rod 2 for moving the lifting device. A vertical plate 3 is fixedly installed on the side wall of the sliding rod 2. The sliding rod 2 is arranged horizontally and is installed between two vertical rods 1 through an electric slider and an electric slide rail, so as to facilitate pushing the sliding rod 2 and the structure on the side wall of the sliding rod 2 upward.

[0031] The side wall of the vertical plate 3 has two vertical grooves symmetrically opened longitudinally, and a rectangular block 7 is slidably installed in the vertical groove 6. The side wall of the two rectangular blocks 7 is fixedly installed with an mounting plate 4, and the bottom of the side wall of the mounting plate 4 is horizontally fixedly installed with a base plate 5. The interior of the vertical groove 6 has a fixing rod that runs longitudinally through the rectangular block 7. The sliding direction of the rectangular block 7 is limited by the fixing rod, and the stability of the rectangular block 7 and the mounting plate 4 is further improved when they slide.

[0032] Two L-shaped rods 18 are symmetrically fixedly installed on the side wall of the vertical plate 3. The L-shaped rods 18 are inserted into the trash can and contact the inner wall of the trash can, thereby further improving the stability of the trash can.

[0033] Two hydraulic cylinders 8 are symmetrically fixedly installed on the side of the vertical plate 3 away from the mounting plate 4. A connecting plate 9 is fixedly installed on the side of the mounting plate 4 away from the bottom plate 5. The telescopic ends of the hydraulic cylinders 8 are fixedly connected to the connecting plate 9. Thanks to the setting of the two L-shaped rods 18 and the two hydraulic cylinders 8, when the garbage can moves to the bottom plate 5, the two hydraulic cylinders 8 are activated, which drives the mounting plate 4 and the bottom plate 5 to move upward until the two L-shaped rods 18 are inserted into the inside of the garbage can to limit the garbage can.

[0034] The mounting plate 4 has two symmetrically arranged sliding grooves 10 on its side wall, and a slider 11 is slidably installed in the sliding groove 10. A horizontal plate 12 is fixedly installed between the two sliders 11. A claw 13 is fixedly installed on the side wall of the horizontal plate 12. A spring 14 is fixedly installed at the lower end of the sliding groove 10. The upper end of the spring 14 is fixedly connected to the bottom of the slider 11. Thanks to the arrangement of the sliding groove 10, slider 11, horizontal plate 12, claw 13 and spring 14, when the trash can is pushed onto the bottom plate 5, the horizontal plate 12 is pressed down first. When the trash can is pushed onto the bottom plate 5, the horizontal plate 12 is released, so that the spring 14 loses its downward pressure and extends upward. The spring 14 pushes the slider 11, the horizontal plate 12 and the claw 13 to move upward, so that the claw 13 is engaged in the groove on the edge of the trash can.

[0035] A limiting rod 15 is fixedly installed longitudinally inside the slide groove 10. A limiting hole is opened through the side wall of the slider 11. The limiting rod 15 slides through the limiting hole opened through the side wall of the slider 11. Thanks to the setting of the limiting rod 15 and the limiting hole, the spring 14 is slidably sleeved to the outside of the limiting rod 15, thereby limiting the extension and contraction of the spring 14 and preventing the spring 14 from bending laterally when compressed. The limiting rod 15 is slidably inserted into the limiting hole opened on the slider 11, thereby effectively limiting the sliding direction of the slider 11 and further improving the stability of the slider 11 and the horizontal plate 12 when sliding.

[0036] The top surface of the base plate 5 has multiple arc-shaped grooves, and ball bearings 16 are rolled inside the arc-shaped grooves. One side of the top surface of the base plate 5 is inclined, and multiple strip-shaped grooves are horizontally opened on the inclined surface of the base plate 5. Traction rollers 17 are rotatably installed inside the multiple strip-shaped grooves. Thanks to the arrangement of the mounting plate 4, the base plate 5, and the traction rollers 17 and ball bearings 16, the trash can is pushed towards the base plate 5. At this time, the trash can is pulled by the multiple traction rollers 17 and the inclined surface of the base plate 5. At the same time, under the action of the multiple ball bearings 16, it is easy to push the trash can to the top surface of the base plate 5. The friction between the bottom of the trash can and the base plate 5 is reduced by the traction rollers 17 on the inclined surface and the ball bearings 16 on the base plate 5, thus making it easier to push the trash can onto the base plate 5.

[0037] Working principle

[0038] When using this trash can lifting auxiliary device, the trash can is first pushed towards the base plate 5. The top surface of the base plate 5 is inclined. Then, the traction roller 17 on the inclined surface and the ball bearings 16 on the base plate 5 reduce the friction between the bottom of the trash can and the base plate 5, making it easier to push the trash can onto the base plate 5. At this time, two hydraulic cylinders 8 are activated simultaneously. The hydraulic cylinders 8 pull the connecting plate 9 and the mounting plate 4 upward, so that the base plate 5 can lift the trash and allow the two L-shaped rods 18 to be inserted into the trash can. At the same time, the two springs 14 push the slider 11, the horizontal plate 12 and the claw 13 upward until the claw 13 is inserted into the edge groove of the trash can, further limiting the trash can.
