Description

Technical Field

[0001] The present invention relates to the technical field of sanitation auxiliary equipment, and in particular to a garbage bin transfer trolley. Background Art

[0002] Trash cans are tools for maintaining the urban environment. For new residential areas on city streets and in good road conditions, garbage trucks can be used to directly transfer the garbage in the trash cans. However, it is not convenient for garbage trucks to directly enter some places (such as university campuses and old residential areas with poor road conditions). In this way, the garbage in the trash cans can only be transferred manually by cleaning staff or by pushing a cart. If the garbage is transferred manually by cleaning staff, there are defects such as low garbage transfer efficiency and high labor intensity; if the garbage is transferred by cleaning staff pushing a cart, although it can improve the efficiency of garbage transfer and reduce labor intensity, there is a problem that the garbage can on the cart is prone to tipping over during the transfer process. For example, the Chinese utility model patent with document number CN206108101 U, with authorization announcement date of April 19, 2017, is entitled "An electric trolley for garbage transfer", which discloses a frame including a table top and handrails, a power box and a controller box are arranged under the table top, a battery is arranged in the power box, wheels are arranged under the table top, wherein the front wheels are universal wheels, the rear wheels are hub motor wheels, and the hub motor wheels are connected to the controller box; a force sensor is fixedly connected to the handrail, and the force sensor is connected to the controller box; a slide rail for placing a trash can is arranged on the table top, and the trash can slides on the slide rail.

[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] like Figure 1 , Figure 2 and Figure 7 As shown, the present invention provides a trash can transfer trolley, including a trolley body 1, and casters 12 are fixedly arranged at the bottom of the trolley body 1. For example, the casters 12 near the head of the trolley body 1 (i.e., the end away from the handle 11) can use universal casters, and the casters 12 near the tail of the trolley body 1 (i.e., the end near the handle 11) can use universal casters with brakes. A handle 11 for pushing or pulling the trolley body 1 is fixedly installed near one end of the trolley body 1 by screws, and the handle 11 is covered with an anti-slip sleeve 111, which has an anti-slip effect and improves the comfort of cleaning personnel when using it. A conveying component 2 is fixedly arranged on the trolley body 1 along its length direction, and a limiting mechanism 4 is fixedly arranged on the conveying component 2. The conveying component 2 helps the trash can 6 to move to the target placement position on the trolley body 1, and the limiting mechanism 4 prevents the trash can 6 from tipping over on the trolley body 1 during transportation.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, further, the conveying assembly 2 includes a fixed block 21, which is fixedly mounted on the trolley body 1 by screws, and there are two fixed blocks 21 and they are parallel and distributed along the length direction of the trolley body 1. The opposite sides of the two fixed blocks 21 are processed with mounting grooves 211, and the mounting grooves 211 have multiple mounting grooves and the multiple mounting grooves 211 are evenly distributed along the length direction of the fixed block 21. The corresponding mounting grooves 211 on the two fixed blocks 21 are rotatably provided with a rotating shaft 23, and the rotating shaft 23 can be rotatably installed in the mounting groove 211 through a deep groove ball bearing. A roller 22 is fixedly sleeved on the rotating shaft 23, and the roller 22 is cylindrical, so that the trash can 6 located on the roller 22 can only slide along the head to tail direction of the trolley body 1, and it is not easy to slide to the two sides of the trolley body 1, that is, the trash can 6 can only move forward and backward on the trolley body 1, and it is not easy to move left and right. In this way, the conveying assembly 2 can help cleaning personnel quickly push the trash can 6 on the trolley to the target placement position, saving time and effort.

[0028] like Figure 1 and Figure 2 As shown, further, the limiting mechanism 4 includes a first limiting plate 41 and a second limiting plate 42, and the first limiting plate 41 and the second limiting plate 42 can be fixedly installed above the conveying component 2 near the two sides through a fixing frame. The first limiting plate 41 and the second limiting plate 42 are parallel and are distributed along the length direction of the conveying component 2. A flexible connector 43 is fixedly provided on the side of the first limiting plate 41 relative to the second limiting plate 42. The flexible connector 43 can be a connecting rope, a connecting chain, or a connecting cloth strip. The number of flexible connectors 43 is 1 to 4, and the number of flexible connectors 43 is selected according to needs. In this embodiment, the number of flexible connectors 43 is 3. A slot 422 is provided on the side of the second limiting plate 42 relative to the first limiting plate 41 and at a position corresponding to the flexible connector 43, and the end of the flexible connector 43 away from the first limiting plate 41 is engaged with the slot 422. The length of the flexible connector 43 is equal to the distance between the first limiting plate 41 and the second limiting plate 42 plus 3 to 5 cm. The flexible connector 43 of such a length has the best limiting effect.

[0029] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, further, the first limit plate 41 is provided with a first slide groove 411 on the side of the second limit plate 42, and the first slide groove 411 is distributed along the length direction of the first limit plate 41. A first slider 45 is slidably provided in the first slide groove 411, and the flexible connector 43 is fixedly connected to the side of the first slider 45 close to the second limit plate 42. A second slide groove 421 is provided on the side of the second limit plate 42 close to the first limit plate 41, and the second slide groove 421 is distributed along the length direction of the second limit plate 42. A clamping groove 422 is provided on the side of the second limit plate 42 close to the first limit plate 41 and close to the position of the second slide groove 421, and the clamping grooves 422 are evenly spaced on the second limit plate 42. A second slider 46 is fixedly connected to the end of the flexible connector 43 away from the first slider 45, and the second slider 46 can slide in the second slide groove 421, and the second slider 46 and the flexible connector 43 form a clamping member that can be clamped with the clamping groove 422. The first limit plate 41 and the second limit plate 42 are both fixed with end plates 44 by screws, and the end plates 44 prevent the first slider 45 from being separated from the first slide groove 411 and the second slider 46 from being separated from the second slide groove 421. The cross section of the first slide groove 411 is T-shaped, and the first slider 45 is in the shape of a straight quadrangular prism. The cross section of the second slide groove 421 is inverted L-shaped, and the second slider 46 is in the shape of a cylinder. The slot 422 is approximately U-shaped. The cross sections of the first limit plate 41 and the second limit plate 42 are both rectangular.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, further, a lifting assembly 3 for adjusting the height of the limiting mechanism 4 is provided between the conveying assembly 2 and the limiting mechanism 4. The lifting assembly 3 is fixedly provided at the bottom positions near both ends of the first limiting plate 41 and the second limiting plate 42. The lifting assembly 3 includes a fixed rod 31 and a telescopic rod 32, and one end of the fixed rod 31 is fixedly installed on the top of the fixed block 21 by screws. A cavity 311 is processed at the end of the fixed rod 31 away from the conveying assembly 2, and the telescopic rod 32 is located in the cavity 311 and can slide along the cavity 311. An adjusting screw 33 is threadedly provided on the outer side surface of the fixed rod 31 away from the conveying assembly 2, and the adjusting screw 33 can be extended into the cavity 311 and conflict with the outer side surface of the telescopic rod 32. The adjusting screw 33 can be loosened by rotating it by hand, and then the position of the telescopic rod 32 can be changed. The end of the telescopic rod 32 away from the fixed rod 31 is fixedly connected to the bottom of the first limiting plate 41 or the second limiting plate 42 by screws. A connecting rod 5 is fixedly installed between the telescopic rod 32 at the bottom of one end of the first limiting plate 41 close to the handle 11 and the telescopic rod 32 at the bottom of one end of the second limiting plate 42 close to the handle 11 by screws. The connecting rod 5 enables the first limiting plate 41 and the second limiting plate 42 to maintain synchronous lifting and lowering adjustment when the limiting mechanism 4 is lifted and lowered.

[0031] like Figures 1 to 7As shown, when in use, the cleaning staff pushes (or pulls) the trolley body 1 to the vicinity of the garbage can 6 to be transferred, and then moves the garbage can 6 to the roller 22 at the head position of the trolley body 1 (i.e., away from the end of the handle 11). Then, the cleaning staff pushes the garbage can 6 by hand to make it slide along the roller 22 to the tail position of the trolley body 1 (i.e., close to the end of the handle 11). At this time, the two sides of the garbage can 6 are limited by the first limiting plate 41 and the second limiting plate 42 respectively, and the end of the garbage can 6 close to the handle 11 can be limited by the connecting rod 5 (or a flexible connecting member 43), and the end of the garbage can 6 away from the handle 11 is limited by another flexible connecting member 43. Repeat the above steps, two or three garbage cans 6 can be placed on the trolley body 1 at a time (depending on the size of the garbage can 6, two large garbage cans 6 can be placed, and three small garbage cans 6 can be placed). In this way, the garbage can 6 on the trolley can be limited by the limiting mechanism 4 to prevent it from tipping over during transportation, thereby improving the stability of the garbage can 6 on the trolley. When it is necessary to adjust the limit mechanism 4 according to different types of trash cans 6, since the spacing between the first limit plate 41 and the second limit plate 42 is fixed, this spacing can basically meet the length dimensions of all types of trash cans 6, so the length direction of the trash can 6 can be made to correspond to the spacing direction of the first limit plate 41 and the second limit plate 42, and then, the position of the flexible connector 43 can be adjusted according to the width of the trash can 6. Specifically, first pull the end of the flexible connector 43 close to the first slider 45 to drive the first slider 45 to move in the first limit The first slide groove 411 of the positioning plate 41 makes the first slider 45 close to the width edge of the trash can 6, and then the end of the flexible connector 43 with the second slider 46 is placed in the second slide groove 421 of the second limiting plate 42, and the flexible connector 43 is placed in the slot 422 close to the width edge of the trash can 6. At this time, the flexible connector 43 can limit the width direction of the trash can 6 (that is, the forward or backward direction of the trolley body 1), completing the adaptive limit adjustment of the limiting mechanism 4 and different models of trash cans 6. When it is necessary to adjust the height of the limiting mechanism 4 according to different models of trash cans 6, first, the cleaning staff manually loosens the adjusting screw 33 on the fixed rod 31 of the lifting mechanism, and then drives the telescopic rod 32 to slide in the cavity 311 of the fixed rod 31 through the first limiting plate 41 or the second limiting plate 42 to achieve a change in the height value of the first limiting plate 41 and the second limiting plate 42 to adapt to different models of trash cans 6. Finally, the cleaning staff manually tightens the adjusting screw 33 to fix the height value of the limiting mechanism 4 and completes the height adjustment process of the limiting mechanism 4.

[0032] The present invention does not require the use of electrical components and has the advantages of simple maintenance and low use cost.

[0033] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
