Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, and specifically relates to a garbage can lifting device. Background Art

[0002] In daily life and industrial production, garbage cans are extremely common and are used to collect and process various wastes. However, during the emptying and replacement of garbage cans, especially when the garbage cans are large in volume or heavy in weight, manual operation is often laborious and inefficient, and may also pose safety hazards, such as sprains or crush injuries. This is particularly true in some places where garbage cans need to be replaced frequently, such as restaurants, hospitals, factories, etc.

[0003] To solve the above problems, improve the replacement and emptying efficiency of garbage cans, and reduce the labor intensity and safety risks of manual operation, a variety of garbage can lifting devices have emerged on the market. Most of these devices use mechanical or hydraulic principles and achieve the automatic lifting and positioning of garbage cans through specific structural designs, thereby facilitating the dumping and replacement of garbage cans.

[0004] However, there are still some deficiencies in the structural design of existing garbage can lifting devices, such as poor stability, uneven lifting, inaccurate positioning of garbage cans, etc. These problems directly affect the use effect and user experience of the devices. Content of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art and provides a garbage can lifting device to solve the problem of poor stability of the existing garbage can lifting device.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: a garbage can lifting device, including a frame, a guide rail is arranged vertically on the frame; a lifting bottom frame and a lifting mechanism connected to the lifting bottom frame are also arranged on the frame; a deflectable garbage can hanging rack is connected to the lifting bottom frame, and pulleys adapted to the guide rail are installed on both the lifting bottom frame and the garbage can hanging rack; a hanging plate is arranged on the outer side of the garbage can hanging rack, and a number of upward-facing hooks are arranged on the hanging plate.

[0007] On the basis of the above technical solution, the utility model can be further improved as follows.

[0008] Further, the guide rail is a U-shaped guide rail, and two groups are arranged oppositely.

[0009] Further, a plurality of pulleys on the lifting bottom frame are arranged oppositely on a single-side guide rail; a single pulley on the garbage can hanging rack is arranged oppositely on a single-side guide rail.

[0010] Further, the top end of the guide rail is bent along the garbage dumping direction.

[0011] Furthermore, a limiting beam is erected along the bent end of the guide rail.

[0012] Furthermore, a bracket is provided on the lifting chassis, and a connecting member is arranged on the trash can hanging rack relative to the bracket; a long groove is formed in the connecting member; a positioning pin adapted to the long groove is installed on the bracket.

[0013] Furthermore, a limiting portion contacting the lifting chassis extends from the bottom of the trash can hanging rack.

[0014] Furthermore, the lifting mechanism includes a hydraulic cylinder, and the output end of the hydraulic cylinder is connected to a lifting frame connected to the lifting chassis.

[0015] Moreover, the trash can lifting device provided by the present utility model has at least the following beneficial effects compared with the prior art:

[0016] 1. The trash can lifting device designed in the present utility model significantly enhances the stability and load-bearing capacity of the device by adopting a U-shaped guide rail and a double-group design arranged oppositely. The two side walls of the U-shaped guide rail effectively limit the movement of the pulley in the vertical direction, preventing derailment, and the symmetric arrangement of the double-group guide rails further ensures the smoothness of the lifting chassis and the trash can hanging rack during the lifting process, greatly reducing shaking and deviation.

[0017] 2. The design of multiple pulleys on the lifting chassis and a single pulley on the trash can hanging rack not only ensures the stability of the lifting process but also takes into account the flexibility of the hanging rack during the dumping operation. Combined with the bending design at the top of the guide rail, the device can naturally guide the trash can hanging rack and the trash can to rotate in a specific direction to achieve accurate dumping of the garbage. At the same time, the setting of the limiting beam provides additional safety protection and prevents accidents.

[0018] 3. Through the cooperation of the bracket provided on the lifting chassis and the connecting member on the trash can hanging rack, especially the adaptation design of the long groove in the connecting member and the positioning pin on the bracket, the trash can hanging rack can deflect or adjust its position relative to the lifting chassis within a certain range, thus easily adapting to trash cans of different sizes and shapes. This design not only improves the versatility of the device but also simplifies the process of replacing the trash can. Description of the Drawings

[0020] Figure 2 is a schematic diagram of the partial structure of the present utility model.

[0021] In the drawings, the list of components represented by each reference numeral is as follows:

[0022] 1. Frame; 2. Guide rail; 3. Lifting chassis; 3.1. Bracket; 3.2. Positioning pin; 4. Trash can hanger; 4.1. Connector; 4.2. Long slot; 4.3. Limiting part; 5. Pulley; 6. Hanging plate; 7. Hook; 8. Limiting beam; 9. Hydraulic cylinder; 10. Lifting frame. Detailed implementation

[0023] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0024] It should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0025] As Figure 1 and Figure 2 As shown, the trash can lifting device of the present utility model design includes a frame 1, on which a guide rail 2 is arranged vertically; a lifting mechanism connected to the lifting chassis 3 and the lifting chassis 3 is also provided on the frame 1; a deflectable trash can hanger 4 is connected to the lifting chassis 3, and pulleys 5 adapted to the guide rail 2 are installed on both the lifting chassis 3 and the trash can hanger 4; a hanging plate 6 is arranged outside the trash can hanger 4, and a number of upward-facing hooks 7 are arranged on the hanging plate 6.

[0026] As an implementation method, the guide rail 2 is a U-shaped guide rail, and two groups are arranged relatively; the two side walls of the U-shaped guide rail can limit the movement of the pulley in the vertical direction to prevent it from derailing. At the same time, the symmetrical arrangement of the two groups of guide rails makes the lifting chassis and the trash can hanger more stable during the lifting process, reducing the possibility of shaking and deviation.

[0027] Specifically, a plurality of pulleys 5 on the lifting chassis 3 are arranged relatively to a single-side guide rail 2, increasing the contact area and friction between the chassis and the guide rail, and improving the stability and safety during the lifting process; the pulley 5 on the trash can hanger 4 is arranged singly relatively to a single-side guide rail 2. Considering that the hanger needs to have a certain degree of flexibility to adapt to the deflection and dumping operations of the trash can, the design of a single pulley reduces the frictional resistance and makes the hanger rotate more smoothly.

[0028] As an implementation method, the top end of the guide rail 2 is bent along the trash can dumping direction, so that when the trash can is lifted to a certain height and dumped, it can naturally guide the trash can hanger 4 and the trash can to rotate in a specific direction, thereby ensuring that the garbage can be accurately dumped in the designated area.

[0029] As an implementation manner, a limiting beam 8 is erected along the bent end of the guide rail 2, which plays a role in safety protection.

[0030] As an implementation manner, a bracket 3.1 is provided on the lifting chassis 3, and a connecting member 4.1 is provided on the trash can hanging rack 4 relative to the bracket 3.1; a long groove 4.2 is formed in the connecting member 4.1; a positioning pin 3.2 adapted to the long groove 4.2 is installed on the bracket 3.1. The long groove 4.2 allows the trash can hanging rack 4 to deflect or adjust its position relative to the lifting chassis 3 within a certain range; the positioning pin 3.2 is adapted to the long groove 4.2 and is used to fix the position of the trash can hanging rack 4 when needed to prevent unnecessary movement or shaking during lifting or tipping.

[0031] As an implementation manner, a limiting portion 4.3 in contact with the lifting chassis 3 extends from the bottom of the trash can hanging rack 4. First of all, it increases the stability of the trash can hanging rack 4 during lifting and prevents it from shifting or tipping due to inertia or external force. Secondly, the limiting portion 4.3 also limits the position of the trash can hanging rack 4 during lifting.

[0032] As an implementation manner, the lifting mechanism includes a hydraulic cylinder 9, and the output end of the hydraulic cylinder 9 is connected to a lifting frame 10 connected to the lifting chassis 3; through the pressure transmission and conversion of hydraulic oil, the lifting frame 10 is pushed to move up and down, thereby driving the lifting chassis 3 and the trash can hanging rack 4 to lift together. This hydraulic lifting method has the advantages of strong power, stable transmission, easy control, etc., and can meet the requirements of the trash can lifting device for stability and accuracy. At the same time, the hydraulic cylinder 9 can also adjust the magnitude and speed of the output force according to actual needs to adapt to trash cans of different weights and sizes.

[0033] The working principle of the present utility model is as follows:

[0034] Initial state:

[0035] The trash can hanging rack 4 is connected to the trash can to be lifted through the hook 7 on the hanging plate 6 to ensure that the trash can is firmly hung on the hanging rack.

[0036] Both the lifting chassis 3 and the trash can hanging rack 4 are provided with pulleys 5 adapted to the guide rail 2 to ensure smooth sliding during lifting.

[0037] Lifting process:

[0038] When it is necessary to lift the trash can, the lifting mechanism (such as the hydraulic cylinder 9) is started, and the lifting frame 10 connected to its output end starts to work.

[0039] The lifting frame 10 drives the lifting chassis 3 to rise vertically along the guide rail 2 through mechanical transmission.

[0040] Since pulley 5 is installed on both the lifting chassis 3 and the trash can hanger 4, and the pulley is adapted to the guide rail 2, the entire lifting process is stable and labor-saving.

[0041] As the lifting chassis 3 rises, the trash can also rises until it reaches the predetermined height or position.

[0042] Flipping and dumping:

[0043] After reaching the predetermined height, the trash can hanger 4 may perform a deflection operation (depending on the device design) to align the opening of the trash can with the dumping area.

[0044] The flipping operation may be achieved through a mechanical structure (such as a linkage mechanism) or a hydraulic cylinder, etc., causing the trash can hanger 4 to rotate a certain angle around a certain axis.

[0045] After flipping, the garbage in the trash can automatically dumps into the designated area under the action of gravity.

[0046] Reset process:

[0047] After the dumping is completed, the lifting mechanism works in reverse, driving the lifting chassis 3 and the trash can hanger 4 to descend along the guide rail 2.

[0048] After descending to the initial position, the trash can hanger 4 resets and is ready for the next lifting operation.
