[0034] Example:

[0035] See also Figure 1-2A car tray reciprocating hoist comprises a tray 1, a plurality of electric rollers 2 arranged at equal distances are installed at the inner end of the tray 1, and a driving assembly 3 and a cleaning assembly 4 are respectively provided in the inner cavity of the tray 1, the driving assembly 3 comprises a mounting plate 301 and a pair of electric push rods 302, the electric push rods 302 are mounted on the inner wall of the tray 1, the mounting plate 301 is fixedly connected to the output end of the electric push rods 302, the cleaning assembly 4 comprises a plurality of annular blocks 401, a brush plate 402 is fixedly connected to the outer end of the annular block 401, the brush plate 402 is located directly below the electric roller 2, and the bottom end of the brush plate 402 abuts against the bottom end of the inner wall of the tray 1.

[0036] A hoist is a large-scale mechanical equipment that transports goods by changing potential energy. The transportation process is completed by using a power machine to drag the flexible wire rope and the transported goods up and down. A vertical reciprocating hoist is equipped with a pallet inside, and the pallet is equipped with multiple electric rollers, so that the goods can be transported into the pallet and then transported vertically.

[0037] In this solution, by starting the internal driving mechanism of the pallet 1, multiple electric rollers 2 can be caused to rotate synchronously in the same direction, so that after the user moves the goods to the side of the pallet 1, the rotating electric rollers 2 can transport the goods to the inner end of the pallet 1, and then transport them in the vertical direction. Since there is a gap between the electric rollers 2 and the bottom of the inner wall of the pallet 1, during the transportation of the goods, debris is easy to fall into the gap space, and is blocked by the electric rollers, making the space difficult to clean. If things go on like this for a long time, the electric rollers may get stuck, affecting the normal use of the elevator.

[0038] See also Figure 3-4 A plurality of first limiting holes 303 arranged at equal intervals are provided on the mounting plate 301, a second limiting hole 404 is provided on the annular block 401, and one end of the electric roller 2 passes through the first limiting hole 303 and the second limiting hole 404 respectively.

[0039] In this solution, during the idle time when the pallet 1 is not loaded with goods, the user can start a pair of electric push rods 302 to advance synchronously, driving the mounting plate 301 to move in the direction close to the electric roller 2, and then driving multiple annular blocks 401 to move. During the movement, the mounting plate 301 and the annular blocks 401 pass through the electric roller 2 through the first limiting hole 303 and the second limiting hole 404 respectively, so even when the electric roller 2 is working, the rotation of the electric roller 2 will not affect the mounting plate 301 and the annular blocks 401.

[0040] See also Figure 4-5A pair of symmetrical positioning posts 403 are fixedly connected to one end of the annular block 401 close to the electric roller 2, a positioning block 5 is fixedly connected to one end of the electric roller 2 close to the annular block 401, a pair of positioning grooves 6 matching the positioning posts 403 are provided on the positioning block 5, a plurality of annular grooves are provided on one end of the mounting plate 301 close to the annular block 401, the annular grooves are located on the outside of the first limiting hole 303, a slider is fixedly connected to one end of the annular block 401 close to the mounting plate 301, and the slider is slidably connected to the annular groove.

[0041] During the movement of the annular block 401, the user simultaneously starts the electric roller 2 to reset. For the reset electric roller 2, a pair of positioning grooves 6 opened on the positioning block 5 fixedly connected at one end thereof will be at the same horizontal position with a pair of positioning posts 403 respectively. Therefore, as the multiple annular blocks 401 move, the positioning posts 403 will be engaged with the positioning grooves 6. Then the user starts the multiple electric rollers 2 to rotate synchronously. At this time, under the limiting action of the engagement of the positioning posts 403 and the positioning grooves 6, the annular block 401 will rotate with the electric roller 2. At the same time, the annular block 401 slides in the annular groove through the slider, and drives the multiple brush plates 402 to rotate synchronously around the multiple electric rollers 2 along the same trajectory. Along with the movement of the multiple brush plates 402, the bottom end of the inner wall of the tray 1 can be continuously cleaned, and the debris can be gradually pushed to the outside of the tray 1, thereby realizing the cleaning of the inner cavity of the tray 1.

[0042] After the cleaning is completed, the user stops the rotation of the multiple electric rollers 2, and then starts a pair of electric push rods 302 to reset, so that the positioning column 403 disengages from the positioning groove 6. At this time, the brush plate 402 will drive the annular block 401 to rotate under the action of gravity until the brush plate 402 stops directly under the electric roller 2. Therefore, during the transportation of goods, the brush plate 402 will not hinder the movement of the goods.

[0043] See also Figure 2 A fan 7 is installed at the bottom end of the inner wall of the tray 1.

[0044] During the process of cleaning the debris, the user can start the fan 7, which outputs wind to the inside of the tray 1. The output wind can blow the debris in the inner cavity of the tray 1, thereby assisting the brush plate 402 to clean the debris, and can further help the brush plate 402 to push the debris out of the tray 1. At the same time, the assistance of wind can also reduce the possibility of debris sticking to the brush plate 402, and better clean the dust deep in the inner cavity of the tray 1 and in dead corners.

[0045] Working principle:

[0046] When in use, by starting the internal driving mechanism of the pallet 1, the multiple electric rollers 2 can be prompted to rotate synchronously in the same direction, so that after the user moves the goods to the side of the pallet 1, the rotating electric rollers 2 can be used to transport the goods to the inner end of the pallet 1, and then transport them in the vertical direction. During the idle time when the pallet 1 is not loaded with goods, the user can start a pair of electric push rods 302 to push synchronously, drive the mounting plate 301 to move in the direction close to the electric roller 2, and then drive the multiple annular blocks 401 to move. During the movement of the annular blocks 401, the user simultaneously starts the electric roller 2 to reset. For the reset electric roller 2, a pair of positioning grooves 6 provided on the positioning block 5 fixedly connected at one end thereof will be at the same horizontal position as a pair of positioning columns 403 respectively. Therefore, as the multiple annular blocks 401 move, the positioning columns 403 will be engaged with the positioning grooves 6. Then the user starts the multiple electric rollers 2 to rotate synchronously. At this time, the positioning columns Under the limiting action of the engagement between 403 and the positioning groove 6, the annular block 401 will rotate with the electric roller 2. At the same time, the annular block 401 slides in the annular groove through the slider, and drives the multiple brush plates 402 to rotate synchronously around the multiple electric rollers 2 along the same trajectory. Along with the movement of the multiple brush plates 402, the bottom end of the inner wall of the tray 1 can be continuously cleaned, and the debris can be gradually pushed to the outside of the tray 1 to achieve the cleaning of the inner cavity of the tray 1. During the cleaning process, the user can start the fan 7, and the fan 7 outputs wind force to the inside of the tray 1. The output wind can blow the debris in the inner cavity of the tray 1, thereby assisting the brush plate 402 to clean the debris. After the cleaning is completed, the user stops the rotation of the multiple electric rollers 2, and then starts a pair of electric push rods 302 to reset, so that the positioning column 403 is separated from the positioning groove 6. At this time, the brush plate 402 will drive the annular block 401 to rotate under the action of gravity until the brush plate 402 stops directly under the electric roller 2.

[0047] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
