Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicles, specifically to a lifting and feeding mechanism. Background Technology

[0002] There are various types of lifting and loading mechanisms for sanitation vehicles, which are used in both food processing trucks and garbage trucks.

[0003] Currently, there are two types of lifting and loading mechanisms for garbage trucks on the market: lever type and chain type. Lever type lifting mechanisms generally use two hydraulic cylinders arranged on the roof of the truck. The hydraulic cylinders lift the connecting rods on both sides, and the lifting frame slides up and down along the track. This type of lifting mechanism is widely used in kitchen waste trucks.

[0004] Another type is the chain-type lifting frame, which uses a single hydraulic cylinder to lift the chain. The lifting frame's lifting speed is twice that of the hydraulic cylinder, and the lifting frame's stroke is also twice that of the hydraulic cylinder.

[0005] The two types mentioned above are commonly used lifting frame structures on the market. They are mainly used in kitchen trucks that have push shovels for unloading. For garbage trucks that require lifting and unloading functions, the hydraulic cylinders are too long, making maintenance more difficult. The hydraulic cylinders are also large, requiring more space and time for disassembly and installation, which can be inconvenient. For places that require the lifting frame to be close to the ground, these two lifting structures cannot meet the needs. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a lifting and feeding mechanism that uses a short telescopic component to achieve long-distance transmission.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A lifting and feeding mechanism, comprising:

[0009] First framework;

[0010] The second frame is located within the first frame;

[0011] The telescopic component has its fixed end fixed to the first frame and its output end connected to a transverse connector. The transverse connector is arranged parallel to the horizontal line, and the telescopic direction of the telescopic component is perpendicular to the horizontal line.

[0012] The inner rotating component assembly has its rotation axis parallel to the horizontal line and is rotatably mounted on the transverse connecting component.

[0013] An internal transmission component assembly, one end of which is connected to the second frame, and the other end of which is fixed in a relative position to the first frame, and the internal transmission component assembly is meshed with the internal rotating component assembly;

[0014] An outer rotating component assembly is rotatably connected to the top of the second frame, and the rotation axis of the outer rotating component assembly is set parallel to the horizontal line;

[0015] An external transmission component assembly has one end fixed relative to the first frame and the other end connected to a lifting platform, and the external transmission component assembly is meshed with the external rotating component assembly.

[0016] The telescopic component extends and retracts to cause the inner rotating component group to drive the inner transmission component group to rotate, and the outer rotating component group to drive the outer transmission component group to rotate, thereby lifting or lowering the second frame and the lifting platform.

[0017] As described above, the lifting and feeding mechanism has a first U-shaped groove on the side of the first frame facing the second frame along the horizontal direction, and first pulleys on both sides of the second frame, with the first pulleys sliding in the first U-shaped groove.

[0018] As described above, the lifting and feeding mechanism includes an inner rotating component group comprising a first inner rotating component and a second inner rotating component, an inner transmission component group comprising a first inner transmission component and a second inner transmission component, an outer rotating component group comprising a first outer rotating component and a second outer rotating component, and an outer transmission component group comprising a first outer transmission component and a second outer transmission component.

[0019] Along the horizontal direction,

[0020] The first inner rotating member and the second inner rotating member are respectively disposed on both sides of the transverse connecting member;

[0021] The first internal transmission component and the second internal transmission component are respectively disposed on both sides of the telescopic component;

[0022] The first outer rotating member and the first outer transmission member are disposed between the first inner rotating member and the second frame.

[0023] The second outer rotating member and the second outer transmission member are disposed between the second inner rotating member and the second frame.

[0024] In the lifting and feeding mechanism described above, the lengths of the inner transmission component group and the outer transmission component group are equal.

[0025] In the lifting and feeding mechanism described above, the length of the inner transmission component group is greater than or equal to the length of the outer transmission component group.

[0026] As described above, in the lifting and feeding mechanism, along a direction perpendicular to the horizontal line, the fixed end of the telescopic member is located in the middle or lower part of the first frame.

[0027] As described above, the lifting and feeding mechanism has a second U-shaped groove on the side of the second frame facing the telescopic member along the horizontal direction, and a second sliding wheel that slides in the second U-shaped groove is provided on the lifting platform.

[0028] In the lifting and feeding mechanism described above, the height of the outer rotating component group is always higher than that of the inner rotating component group.

[0029] As described above, when the telescopic component is in the retracted state, the lifting platform is in contact with the ground surface.

[0030] As described above, when the telescopic component is in the extended state, the lifting platform is located at the top of the first frame.

[0031] The beneficial effects of this utility model are:

[0032] In this design, the telescopic component extends, at which point the inner rotating component group rotates, and the inner transmission component group rotates. Under the lifting of the inner transmission component, the second frame rises. Simultaneously, the outer rotating component group rotates, the outer transmission component group rotates, and the lifting platform rises synchronously. Since the lifting platform is located on the second frame, while the telescopic component lifts the second frame, it also drives the lifting platform to rise. With the cooperation of the outer transmission component group, the actual moving distance of the lifting platform is greater than the extension distance of the telescopic component, and long-distance transmission can be achieved through the short telescopic component.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0053] Reference Figures 1 to 6 This embodiment provides a lifting and feeding mechanism, including:

[0054] First Framework 1;

[0055] The second frame 2 is located within the first frame 1;

[0056] The telescopic component 3 has its fixed end fixed to the first frame 1 and its output end connected to a transverse connector 31. The transverse connector 31 is arranged parallel to the horizontal line, and the telescopic direction of the telescopic component 3 is perpendicular to the horizontal line.

[0057] The inner rotating component assembly 41 has its rotation axis parallel to the horizontal line and is rotatably mounted on the transverse connecting component 31.

[0058] Internal transmission component assembly 42, one end of which is connected to the second frame 2 ( Figure 6 (a1, a2 in the middle), the other end is fixed relative to the first frame 1, and the inner transmission component group 42 is meshed with the inner rotating component group 41;

[0059] An outer rotating component assembly 51 is rotatably connected to the top of the second frame 2, and the rotation axis of the outer rotating component assembly 51 is set parallel to the horizontal line;

[0060] External transmission component assembly 52, one end of which is connected to the first frame 1 ( Figure 6 The relative positions of b1 and b2 are fixed, and the other end is connected to a lifting platform 6. Figure 6 (b3, b4 in the text), and the external transmission component group 52 is meshed with the external rotating component group 51;

[0061] The telescopic component 3 extends and retracts, so that the inner rotating component group 41 drives the inner transmission component group 42 to rotate, and the outer rotating component group 51 drives the outer transmission component group 52 to rotate, thereby lifting or lowering the second frame 2 and the lifting platform 6.

[0062] To clearly illustrate the working principle of this scheme, D1 and d1 are defined as follows: on the inner transmission component group 42, the distance from the connection between the second frame 2 and the inner transmission component group 42 to the inner rotating component group 41 is defined as D1; ​​on the outer transmission component group 52, the distance from the outer rotating component group 51 to the lifting platform 6 is defined as d1.

[0063] The working principle of this embodiment is as follows:

[0064] Figure 1 As shown, the lifting and feeding mechanism is in its initial state. Sanitation workers can place the garbage cans on the lifting platform 6. The telescopic part 3 extends, the inner rotating part group 41 rotates, the second frame 2 rises, and the length of the d1 part of the outer rotating part group 51 and the length of the D1 part of the inner rotating part group 41 become shorter, thereby driving the lifting platform 6 to rise to the top.

[0065] on the contrary, Figure 2 As shown, the telescopic component 3 retracts, the inner rotating component group 41 rotates, the second frame 2 descends, and the length of the d1 part of the outer rotating component group 51 and the D1 part of the inner rotating component group 41 increases, thereby driving the lifting platform 6 to descend to the bottom.

[0066] The item carried on the lifting platform 6 is a trash can.

[0067] Reference Figure 7 As an example, the inner rotating component group 41 and the outer rotating component group 51 are gears, and the inner transmission component group 42 and the outer transmission component group 52 are chains.

[0068] As an example, the telescopic component 3 is a hydraulic cylinder. The hydraulic cylinder can generate a large thrust and the movement is relatively smooth. It is especially suitable for use on garbage trucks. It can prevent the speed of the lifting platform from rising or falling sharply due to excessive telescopic speed, which would cause the items carried on it to fall off due to shaking.

[0069] Reference Figure 6 As an example of an application scenario, the lifting and feeding mechanism in this embodiment can be applied to a garbage truck. In use, this structure is set on the outer side wall of the garbage collection box of the garbage truck, that is, the first frame 1 is fixed on the garbage collection box, the end of the inner transmission component group 42 that is fixed in a position relative to the first frame 1 is fixed on the side wall of the garbage collection box, and the end of the outer transmission component group 52 that is fixed in a position relative to the first frame 1 is fixed on the side wall of the garbage collection box. A garbage dumping inlet 8 is opened above the garbage collection box. The garbage can is placed on the lifting platform 6, and the telescopic component 3 drives the lifting platform 6 to rise and fall, so as to lift the garbage can to one side of the garbage dumping inlet 8. The garbage can is flipped over, so that the garbage in the garbage can can be poured into the garbage collection box. The telescopic component 3 is reset, so that the garbage can can be removed from the lifting platform 6, completing one garbage dumping operation.

[0070] In one embodiment, along the horizontal direction, that is, perpendicular to the telescopic direction of the telescopic member 3 and the lifting direction of the inner transmission member group 42 and the outer transmission member group 52, the first frame 1 is provided with a first U-shaped groove (not shown in the figure) on the side facing the second frame 2, and the second frame 2 is provided with first pulleys 21 on both sides of the lateral direction, and the first pulleys 21 slide in the first U-shaped groove.

[0071] The first U-shaped groove and the first pulley 21 cooperate to determine the movement path of the second frame 2, preventing the second frame 2 from swinging back and forth during the pulling process, and ensuring that the lifting platform 6 can rise and fall stably. In terms of connection stability, it can prevent the inner transmission component group 42 from detaching from the inner rotating component group 41 and the outer transmission component group 52 from detaching from the outer rotating component group 51, which would render the mechanism unusable and improve the stability of the mechanism.

[0072] In one embodiment, the inner rotating component group 41 includes a first inner rotating component 411 and a second inner rotating component 412; the inner transmission component group 42 includes a first inner transmission component 421 and a second inner transmission component 422; the outer rotating component group 51 includes a first outer rotating component 511 and a second outer rotating component 512; and the outer transmission component group 52 includes a first outer transmission component 521 and a second outer transmission component 522.

[0073] Along the horizontal direction,

[0074] The first inner rotating member 411 and the second inner rotating member 412 are respectively disposed on both sides of the transverse connecting member 31;

[0075] The first internal transmission component 421 and the second internal transmission component 422 are respectively disposed on both sides of the telescopic component 3;

[0076] The first outer rotating member 511 and the first outer transmission member 521 are disposed between the first inner rotating member 411 and the second frame 2.

[0077] The second outer rotating member 512 and the second outer transmission member 522 are disposed between the second inner rotating member 412 and the second frame 2.

[0078] The structural layout design of the inner rotating component group 41, the inner transmission component group 42, the outer rotating component group 51, and the outer transmission component group 52 in this embodiment has a stable rotating structure and transmission structure on both the left and right sides along the telescopic axis of the telescopic component 3, which further ensures that the lifting platform 6 can rise and fall stably.

[0079] Reference Figure 1 and Figure 3 More specifically, with the telescopic shaft of the telescopic member 3 as the axis, the first inner rotating member 411 and the second inner rotating member 412 are symmetrically arranged, the first inner transmission member 421 and the second inner transmission member 422 are symmetrically arranged, the first outer rotating member 511 and the second outer rotating member 512 are symmetrically arranged, and the first outer transmission member 521 and the second outer transmission member 522 are symmetrically arranged. This layout helps to balance the forces on both sides of the parallel telescopic member 3, reduce the impact of uneven forces on both sides of the transverse connecting member 31 on the telescopic function of the telescopic member 3, and avoid the situation where the second frame 2 tilts and gets stuck in the first frame 1.

[0080] In one embodiment, the inner transmission component group 42 and the outer transmission component group 52 are of equal length, which is beneficial for production assembly. There is no need to distinguish between their lengths, reducing the situation of repeated disassembly and assembly due to incorrect assembly caused by different lengths. While achieving the function of this embodiment, it is also beneficial to improve production speed.

[0081] In one embodiment, the length of the inner transmission component group 42 is greater than or equal to the length of the outer transmission component group 52.

[0082] In one embodiment, along a direction perpendicular to the horizontal line, the fixed end of the telescopic member 3 is located in the middle or lower part of the first frame 1. In this embodiment, there is enough space for the second frame 2 to rise, and the distance that the second frame 2 and the first frame 1 can move is also long, and the lifting space of the lifting platform 6 is also large.

[0083] Reference Figure 4 , Figure 8 and Figure 9 In one embodiment, along the horizontal direction, the second frame 2 is provided with a second U-shaped groove 22 on the side facing the telescopic member 3. The lifting platform 6 is provided with a second sliding wheel 61 that slides in the second U-shaped groove 22. In this embodiment, the function of the second U-shaped groove 22 and the second sliding wheel 61 is the same as the function of the first U-shaped groove and the first sliding wheel 21. It can stabilize the movement path of the lifting platform 6 and prevent the lifting platform 6 from swinging back and forth during the pulling process, thus ensuring good stability.

[0084] Reference Figure 1 and Figure 3 In one embodiment, the height of the outer rotating component group 51 is always higher than that of the inner rotating component group 41.

[0085] Reference Figure 1 In one embodiment, when the telescopic member 3 is in the retracted state, the lifting platform 6 is in contact with the ground surface, making it convenient for workers to place the trash can on the lifting platform 6.

[0086] Reference Figure 3 In one embodiment, when the telescopic member 3 is in the extended state, the lifting platform 6 is located on top of the first frame 1, which facilitates workers to empty the trash from the trash can into the trash collection bin.

[0087] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
