Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically to a lifting mechanism and a grinding and cleaning vehicle. Background Technology

[0002] With urbanization, many cleaning tasks are now being carried out using equipment to reduce the intensity of manual labor and improve efficiency. For example, cleaning containers is particularly difficult because their bottoms have grooves, and the dock environment can be extremely hot on sunny days, creating a harsh working environment. Prolonged work can lead to dehydration or heatstroke. Cleaning trucks can effectively address these issues.

[0003] In existing cleaning vehicles, the cleaning brushes need to be raised and lowered to perform cleaning operations during work; when resting, parking, or moving to other containers, the cleaning brushes need to be raised to protect them and prevent ineffective work. However, the existing lifting devices cannot accurately determine whether the cleaning brushes are in the correct position; and the lifting height varies slightly depending on the container, resulting in poor compatibility and ultimately suboptimal cleaning performance. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting mechanism and a grinding and cleaning vehicle, which aims to improve the problem that the lifting mechanism of existing cleaning vehicles cannot accurately determine the lifting position.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lifting mechanism, comprising:

[0006] A fixed frame is provided with a slide rail on one side, and a power unit is provided on one end of the fixed frame located on the slide rail.

[0007] A sliding frame, slidably mounted on the slide rail, and a linkage belt synchronously driving the sliding frame to move is provided between the output end of the power unit and the sliding frame; and

[0008] A detector is mounted on the linkage belt, and a detection plate for detection is mounted on the linkage belt.

[0009] Preferably, the linkage belt is a chain, nylon rope, or steel cable.

[0010] Preferably, the linkage belt is a chain, and the output shaft of the power unit is provided with a sprocket that meshes with the chain;

[0011] One end of the chain is mounted on the sliding frame, which is also equipped with a spring, and the other end of the chain is equipped with a rope connected to the spring.

[0012] Preferably, the slide rail consists of two symmetrically arranged track grooves on one side of the fixed frame. The track grooves pass through the end face of the fixed frame with the power unit at one end. The sliding frame is provided with pulleys that slide in cooperation with the track grooves.

[0013] Preferably, the pulleys are provided in multiple pairs, and the multiple pairs of pulleys are arranged side by side on the same side.

[0014] Preferably, the bottom of the fixed frame is provided with a first fixed shaft, the top of the sliding frame is provided with a second fixed shaft, one end of the spring is provided on the second fixed shaft, and the rope passes around the first fixed shaft and is provided on the other end of the spring.

[0015] Preferably, the bottom of the sliding frame is provided with a mounting bracket, and the mounting bracket is provided with a plurality of mounting holes.

[0016] A grinding and cleaning vehicle is also provided, including the aforementioned lifting mechanism.

[0017] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] 1. A slide rail is installed on a fixed frame to allow the sliding frame to move, and the required movement trajectory is designed. Then, a linkage belt and power unit are used to drive the sliding frame, enabling it to move along the slide rail. The detector and detection plate located on the linkage belt can perform real-time detection. If the linkage belt is taut, the distance between the detector and the detection plate is the same, indicating that the lifting mechanism is in a suspended state. If the linkage belt is slack, the distance between the detector and the detection plate changes, thus indicating that the lifting mechanism is in contact with an object and is operating. This achieves precise knowledge of the lifting mechanism's operating status, improving operational accuracy. Attached Figure Description

[0031] Example 1

[0032] Please refer to Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a lifting mechanism, including a fixed frame 10, a sliding frame 20, and a detector 30. A slide rail 101 is provided on one side of the fixed frame 10, and a power unit 102 is provided on one end of the fixed frame 10 located on the slide rail 101. The power unit 102 can be a motor. The sliding frame 20 is slidably disposed on the slide rail 101. A linkage belt 201 is provided between the output end of the power unit 102 and the sliding frame 20 to synchronously drive the sliding frame 20 to move. The detector 30 is disposed on the linkage belt, and a detection piece 301 for detection by the detector 30 is disposed on the linkage belt 201.

[0033] Specifically, a slide rail 101 is set on the fixed frame 10 to allow the sliding frame 20 to move, and the required movement trajectory is designed. Then, a linkage belt 201 and a power unit 102 are used to drive the sliding frame 20, achieving the purpose of moving the sliding frame 20 along the slide rail 101. The detector 30 and detection plate 301 located on the linkage belt 201 can perform real-time detection. If the linkage belt 201 is taut, the distance between the detector 30 and the detection plate 301 is the same, indicating that the lifting mechanism is in a suspended state. If the linkage belt 201 is slack, the distance between the detector 30 and the detection plate 301 changes, thus determining that the lifting mechanism is in contact with an object and is operating, achieving precise knowledge of the lifting mechanism's operating status and improving operational accuracy.

[0034] In this embodiment, the detector 30 can be an infrared detector 30 or a position detector 30, such as a low-power infrared ranging module of model WTU201F2 B004 or a displacement sensor of model NOVOTECHNIK. This allows for real-time monitoring to determine the state of the sliding frame 20.

[0035] Furthermore, in this embodiment, the linkage belt 201 is a chain, nylon rope, or steel cable. Preferably, it is a chain, which has stable transmission performance and sufficient strength to ensure the stability of the lifting and lowering of the sliding frame 20.

[0036] like Figure 1 and Figure 2As shown, in this embodiment, when the linkage belt 201 is a chain, a sprocket that meshes with the chain is provided on the output shaft of the power unit 102; one end of the chain is provided on the sliding frame 20, and a spring 202 is also provided on the sliding frame 20; the other end of the chain is provided with a rope 203 connected to the spring 202. Through the chain part meshing with the sprocket for transmission, and the other part connected by the rope 203 (which can be a steel wire rope), combined with the use of the spring 202, an effective buffering effect can be formed, making the sliding frame 20 and the chain flexibly connected. During the cleaning process, if there are protrusions or changes in the cleaning surface as the sliding frame 20 moves horizontally with the trolley, it can be automatically adjusted longitudinally to avoid impact damage to the sliding frame 20 and improve its practicality.

[0037] Specifically, the lifting mechanism is installed vertically, which can achieve the purpose of lifting or lowering by using ropes 203 and chains to drive upward movement, and by using the reverse rotation of the power unit 102 and the weight of the sliding frame 20 to lower downward movement.

[0038] In this embodiment, the slide rail 101 consists of two symmetrically arranged track grooves on one side of the fixed frame 10. The track grooves penetrate the end face of the fixed frame 10 with the power unit 102. The sliding frame 20 is provided with pulleys 204 that slide in cooperation with the track grooves. The pulleys 204 and the slide rail 101 work together to form a stable cooperation structure, thereby forming a stable lifting and lowering movement and providing a stable lifting and lowering trajectory.

[0039] like Figure 3 As shown, in this embodiment, multiple pairs of pulleys 204 are provided. These multiple pairs of pulleys 204 are arranged side by side on the same side, which allows for more stable installation in the track groove, forming a more stable assembly purpose, and also providing a stable lifting and moving effect.

[0040] like Figure 2 As shown, in this embodiment, a first fixed shaft 103 is provided at the bottom of the fixed frame 10, and a second fixed shaft 205 is provided at the top of the sliding frame 20. One end of the spring 202 is mounted on the second fixed shaft 205, and the rope 203 passes around the first fixed shaft 103 and is mounted on the other end of the spring 202. The design of the first fixed shaft 103 forms the effect of a fixed pulley 204, changing the direction of the rope 203 and creating a positioning point to prevent the rope 203 from deviating, thus providing good guidance and limiting effects for the rope 203. The second fixed shaft 205 can also be installed at a position higher than the first fixed shaft 103 in terms of water level, so that the sliding frame 20 does not experience resistance from the rope 203 when descending, improving practicality.

[0041] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the bottom of the sliding frame 20 is provided with a mounting frame 206, and the mounting frame 206 is provided with a plurality of mounting holes 2061. The design of the mounting frame 206 and the mounting holes 2061 allows the cleaning brush to be fixedly installed through the mounting holes 2061, so as to achieve the cleaning effect of the cleaning brush being raised and lowered by the lifting mechanism.

[0042] Example 2

[0043] This embodiment provides a polishing and cleaning cart, including a lifting mechanism as described in Embodiment 1. The lifting mechanism can drive the cleaning brush in the polishing and cleaning cart to move up and down. Specifically, during the cleaning process, if there are protrusions or changes on the cleaning surface while the sliding frame moves horizontally with the cart, it can automatically adjust longitudinally to avoid impact damage to the sliding frame and improve practicality.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
