Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to an elevator guide rail cleaning device. Background Art

[0002] At present, during the operation of the elevator car, the guide rails installed in the elevator shaft on the market will produce dirt or impurities on the running surface of the elevator car on the guide rails. Over time, it will affect the comfort of the elevator operation. Therefore, the elevator guide rails need to be cleaned every once in a while to ensure the comfort of the elevator operation. Cleaning the elevator guide rails is basically completed by professional staff through mutual cooperation. Under normal circumstances, this cleaning work requires at least two people to cooperate with each other. One person is responsible for operating the elevator at the maintenance speed on the top of the elevator car, and the other person uses detergent and cotton cloth to clean the elevator guide rails. Although this cleaning method can meet the cleaning requirements of the elevator guide rails, it also has certain disadvantages, such as: 1. Low work efficiency; 2. It occupies more human resources. For this working mode, we urgently need a convenient guide rail cleaning auxiliary device that can not only improve work efficiency but also be operated by one person. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] Example: See Figure 1An elevator guide rail cleaning device includes a bracket 1 for installation on the top of an elevator car. In this embodiment, the bracket 1 is an L-shaped plate structure, the horizontal section of which is fixedly connected to the roof of the elevator car, and the vertical section is vertically arranged and used to install auxiliary equipment. In this embodiment, a scrubbing device and an adjusting mechanism connected to the scrubbing device are installed on the vertical section of the bracket 1. The adjusting mechanism can make the scrubbing device approach or move away from the running guide rail 2 of the elevator car, and the scrubbing device can contact the running surface of the elevator car on the guide rail 2 after approaching the guide rail 2; specifically, the cross-section of the guide rail 2 is T-shaped, and the side of its web is the running surface of the elevator car on the guide rail 2. Specifically, three guide wheels are installed at the position of the elevator car relative to the guide rail 2, and they roll and fit on the three side surfaces of the web of the guide rail 2 respectively. Correspondingly, the scrubbing device includes a scrubbing seat 3, on which a U-shaped groove corresponding to the web of the guide rail 2 is provided, and a scrubbing sponge 4 is fitted on the groove wall of the U-shaped groove. When the scrubbing seat 3 is close to the guide rail 2, the U-shaped groove can be sleeved on the web of the guide rail 2, and the scrubbing sponge 4 can contact the side of the web of the guide rail 2. In this way, when the cleaning personnel stand on the top of the elevator car to operate the elevator car to move up and down, the scrubbing sponge 4 can wipe the running surface of the guide rail 2 to remove impurities or dust on the running surface of the guide rail 2. In specific implementation, the groove walls on the opposite sides of the U-shaped groove can be set to be inclined, so that the groove walls on both sides form an eight-shaped structure, so that the scrubbing sponge 4 is squeezed by the scrubbing seat 3 and the guide rail 2, and the upper part is denser and the lower part is looser, which can better make the cleaning liquid on the running surface of the guide rail 2 adsorbed on the lower part of the scrubbing sponge 4, reducing the residue after scrubbing.

[0016] In order to improve the cleaning effect, a cleaning liquid supply device is also installed on the bracket 1. The cleaning liquid supply device is located below the scrubbing device and can supply cleaning liquid to the running surface of the elevator car on the guide rail 2. Specifically, the cleaning liquid supply device includes a cleaning liquid tank 9 for storing cleaning liquid, and a cleaning pump is installed at the bottom of the cleaning liquid tank 9. The water inlet of the cleaning pump is connected to the cleaning liquid tank 9, and the water outlet is connected to the supply pipe 10. The end of the supply pipe 10 extends from the cleaning liquid tank 9 and is opposite to the running surface of the elevator car on the guide rail 2. The supply pipe 10 can adopt a hose that can maintain deformation, such as a corrugated pipe, so as to manually adjust the position and direction of the end of the supply pipe 10, so as to facilitate the supply of cleaning liquid to the running surface of the guide rail 2. In this embodiment, a nozzle can be installed at the end of the supply pipe 10, which can be an atomizing nozzle or a water curtain nozzle to ensure uniform spraying of the cleaning liquid. During implementation, the cleaning pump can be connected to the elevator control system, so that when the elevator maintenance mode is started, the cleaning pump can spray cleaning liquid on the running surface of the guide rail 2 as the elevator runs, further improving the level of automation and making it easier for a single person to complete the cleaning of the guide rail 2.

[0017] In this embodiment, the adjustment mechanism includes a fixed seat 5 installed on the bracket 1 and a sliding seat 6 installed on the fixed seat 5. The scrubbing device is fixedly installed on the sliding seat 6. A sliding hole 7 is opened on the fixed seat 5. The sliding seat 6 is slidably connected with the fixed seat 5 by a bolt passing through the sliding hole 7. An adjusting bolt 8 is also installed on the bracket 1. The adjusting bolt 8 is connected to the sliding seat 6. By rotating the adjusting bolt 8, the sliding seat 6 can be driven to slide along the sliding hole 7, so that the scrubbing device can approach or move away from the guide rail 2, so that the scrubbing device can withdraw from the running surface of the guide rail 2 when the elevator is in normal operation, thereby reducing friction and extending the service life of the scrubbing device.

[0018] In addition, a liquid level sensor is installed on the cleaning liquid tank 9 to determine the remaining cleaning liquid in the cleaning liquid tank 9 so as to add it in time.

[0019] The utility model has a scrubbing device and a cleaning liquid supply device installed on the top of the elevator car. The scrubbing device can be made to contact with the running surface of the guide rail through an adjusting mechanism, and the cleaning liquid is supplied to the running surface of the guide rail through the cleaning liquid supply device. Both can be operated by one person, so that one person can stand on the top of the elevator car and independently operate the operation of the elevator and clean the guide rail. The cleaning efficiency is higher, the human resources are less occupied, the structure is simple, and the operation is convenient.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
