Description

Technical Field

[0001] This utility model relates to the field of guide rail cleaning technology, and in particular to an elevator guide rail cleaning device. Background Technology

[0002] A search revealed Chinese patent CN222312439U, which discloses an elevator guide rail cleaning device. This device includes a bracket for installation on the top of an elevator car. A scrubbing device and an adjustment mechanism connected to the scrubbing device are mounted on the bracket. The adjustment mechanism allows the scrubbing device to move closer to or further away from the elevator car's guide rails, ensuring that the scrubbing device, when close to the guide rails, can contact the elevator car's running surface on the guide rails. A cleaning fluid supply device is also mounted on the bracket, located below the scrubbing device, and supplies cleaning fluid to the elevator car's running surface on the guide rails. This invention, by using a scrubbing device and cleaning fluid supply device installed on the top of the elevator car, allows one person to independently operate the elevator and clean the guide rails while standing on top of the elevator car. This results in higher cleaning efficiency, less manpower required, a simpler structure, and easier operation.

[0003] The above-mentioned patent has the following shortcomings: The above-mentioned patent uses a scrubbing sponge to contact the guide rails and then clean the guide rails. However, the spacing between the scrubbing seats in the above-mentioned patent is fixed, and it can only be used to scrub a limited type of guide rail. Its use is limited, and the spacing between the scrubbing sponges cannot be adjusted, which may result in incomplete cleaning. Therefore, it is urgent to solve this problem. Utility Model Content

The adjustable cleaning mechanism includes a fixed housing. Two bidirectional lead screws are rotatably connected to the inner walls of the fixed housing. Each of the two outer walls of the bidirectional lead screws has a matching second sliding block. A connecting groove is provided at the end of the fixed housing near the guide rail. A connecting rod is fixed to one end of each of the two second sliding blocks, and an adjusting plate is fixed to the other end of each connecting rod. A scrubbing sponge is installed on the side of each adjusting plate that is close to each other. A second knob is fixed to one side of the bidirectional lead screw. By adjusting the distance between the two scrubbing sponges using the bidirectional lead screw, the guide rail can be more closely fitted, resulting in a more thorough cleaning.

[0007] Preferably, a ratchet is fixed to the other side of the bidirectional lead screw, and a pawl is rotatably connected to one side of the fixed housing via a torsion spring, and the pawl engages with the ratchet.

[0008] Preferably, a fixing plate is fixed to the top of one end of the bracket, and an installation groove is provided at the center of the top of the fixing plate. A first lead screw is rotatably connected to both ends of the inner wall of the installation groove. A first sliding block with a matching sliding sleeve is provided on the outer wall of the first lead screw, and the top of the first sliding block is fixed to the bottom of the fixing shell. A first knob is fixed to the end of the first lead screw away from the fixing shell.

[0009] Preferably, the top two sides of the fixing plate are provided with sliding grooves, and sliders are slidably provided inside the sliding grooves. The tops of the two sliders are respectively fixed to the bottom two sides of the fixing shell.

[0010] Preferably, the spraying mechanism includes a connecting plate fixed to the bottom of one end of the support, and a liquid storage tank is fixed to the top of the connecting plate. A liquid pump is installed at the top of one end of the liquid storage tank. The inlet end of the liquid pump is connected to the bottom of the inside of the liquid storage tank through a conduit.

One end of the outlet pipe is connected to several connecting mist nozzles.

[0011] Preferably, two fixing brackets are fixed at one top end of the connecting plate, and elastic blocks are provided at both ends of the top of the two fixing brackets, so that the two sides of the liquid outlet tube can be locked inside the elastic blocks.

[0012] Preferably, a handle is fixed to the bottom of the liquid outlet tube.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Due to the adoption of an adjustable cleaning mechanism, the second knob can drive the bidirectional lead screw to rotate, which in turn drives the two second sliding blocks to move closer to each other, and drives the two adjusting plates to move closer to each other, so that the scrubbing sponge is in close contact with both sides of the guide rail, thereby achieving an efficient cleaning effect on the guide rail. Moreover, the adjustable design allows the cleaning mechanism to adapt to guide rails of different specifications and shapes, thus improving its applicability. Attached Figure Description

[0022] The adjustable cleaning mechanism includes a fixed housing 4. A bidirectional lead screw 404 is rotatably connected to both sides of the inner wall of the fixed housing 4. The outer walls of both sides of the bidirectional lead screw 404 are provided with matching second sliding sleeve moving blocks 405. A connecting limiting groove 406 is opened at one end of the fixed housing 4 near the guide rail 2. A connecting rod 407 is fixed to one end of each of the two second sliding sleeve moving blocks 405. An adjusting plate 401 is fixed to the other end of each of the two connecting rods 407. A scrubbing sponge 402 is installed on the side of the two adjusting plates 401 that are close to each other. A second knob 403 is fixed to one side of the bidirectional lead screw 404. By adjusting the distance between the two scrubbing sponges 402 through the bidirectional lead screw 404, the guide rail 2 can be more closely fitted, making the cleaning more thorough.

[0023] In this utility model, a ratchet 408 is fixed on the other side of the bidirectional lead screw 404, and a pawl 409 is rotatably connected to one side of the fixed housing 4 via a torsion spring, and the pawl 409 engages with the ratchet 408.

[0024] In this utility model, a fixing plate 3 is fixed to the top of one end of the bracket 1. An installation groove is provided at the center of the top of the fixing plate 3. The two ends of the inner wall of the installation groove are rotatably connected to a first lead screw 303. The outer wall of the first lead screw 303 is provided with a matching first sliding block 304. The top of the first sliding block 304 is fixed to the bottom of the fixing shell 4. A first knob 305 is fixed to the end of the first lead screw 303 away from the fixing shell 4.

[0025] In this utility model, the top two sides of the fixing plate 3 are provided with sliding grooves 301, and the sliding grooves 301 are all provided with sliding sliders 302. The tops of the two sliders 302 are respectively fixed to the bottom two sides of the fixing shell 4.

[0026] In this utility model, the spraying mechanism includes a connecting plate fixed to the bottom of one end of the bracket 1, and a liquid storage tank 5 is fixed to the top of the connecting plate. A liquid pump 501 is installed on the top of one end of the liquid storage tank 5. The water inlet of the liquid pump 501 is connected to the bottom of the inside of the liquid storage tank 5 through a conduit. The water outlet of the liquid pump 501 is connected to a connected delivery pipe 502. The other end of the delivery pipe 502 is connected to a connected outlet pipe 503. One end of the outlet pipe 503 is connected to several connected mist nozzles 504.

[0027] In this utility model, two fixing brackets 505 are fixed at one end of the top of the connecting plate. Both ends of the top of the two fixing brackets 505 are provided with elastic blocks 506, and the two sides of the liquid outlet pipe 503 can be locked inside the elastic blocks 506.

[0028] In this invention, a handle 507 is fixed to the bottom of the liquid outlet pipe 503.

[0029] Working principle: During use, the cleaning personnel stand on top of the elevator car, place the bracket 1 on top of the car, and then fix the bracket 1 to the top using bolts or other fixing devices. Then, by rotating the first knob 305, the first knob 305 drives the first lead screw 303 to rotate, which in turn moves the first sliding block 304 with a sliding sleeve. The first sliding block 304 moves the fixed housing 4, which in turn moves the slider 302 inside the slide groove 301. The fixed housing 4 then moves the two adjusting plates 401 closer to the sides of the guide rail 2, moving the cleaning sponge 402 to the appropriate position. When this is done, the rotation of the first knob 305 is stopped. Then, the second knob 403 is rotated, which drives the bidirectional lead screw 404 to rotate. The bidirectional lead screw 404 moves the two limiting slots 406 closer together, and then... The connecting rod 407 moves within the limiting groove 406, causing the corresponding adjusting plate 401 to move and bringing the two cleaning sponges 402 closer together and into contact with both sides of the guide rail 2. This ensures the cleaning sponges 402 adhere tightly to the outer walls of both sides of the guide rail 2, resulting in a more thorough cleaning. Then, by connecting the liquid pump 501 to the elevator control system and supplying it with power, the pump 501 extracts the cleaning fluid from the storage tank 5 and delivers it to the delivery pipe 502. The fluid is then delivered to the outlet pipe 503, which sprays it through the mist nozzle 504 to clean the surface of the guide rail 2. The angle of the cleaning fluid spray can be easily controlled using the handle 507, or the outlet pipe 503 can be secured in the elastic block 506. This makes the process convenient and simple.
