Description

Technical Field

[0001] The utility model relates to the technical field of elevator maintenance, in particular to a maintenance and repair device for elevators. Background Art

[0002] Elevators are one of the essential lifting equipment for high-rise residential buildings in modern cities. To ensure their safety, periodic maintenance and inspection of various elevator components is very necessary. With the continuous development of related technologies, some targeted maintenance and inspection technologies have also been made public. For example, the patent document with application number 202320868162.1 discloses an inspection and repair equipment for elevator maintenance, which "is provided with a liquid spray barrel, a water absorption sleeve, a sealing bearing and a rotating sleeve, and anti-corrosion paint is added to the liquid spray barrel through the liquid filling port, and flows into the water absorption sleeve through the liquid spray hole, and is tightly attached to the elevator compensation chain through the water absorption sleeve, and then the anti-corrosion paint is applied. By applying the anti-corrosion paint to the outside of the elevator compensation chain, the elevator compensation chain is prevented from rusting and the service life of the elevator compensation chain is extended."

[0003] However, in reality, single-sided roller coating will cause part of the elevator compensation chain to be coated while the other part is not, and the maintenance effect is average. Secondly, during the roller coating process, excessive anti-corrosion or lubricating solution will drip in multiple places as the elevator compensation chain moves, which is wasteful and not conducive to the overall cleanliness of the elevator. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a maintenance and repair device for an elevator, which solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a maintenance and repair device for an elevator, comprising an inspection platform and an elevator compensation chain, wherein a step groove is provided inside the inspection platform, wherein a support frame plate and a composite processing box are respectively nested in the step groove, wherein the composite processing box is fixedly sleeved on the inner side of the middle portion of the support frame plate, and both sides of the middle portion of the composite processing box are provided with a clearance groove, wherein one end of the elevator compensation chain passes through the clearance groove and slides on the top surface of the inspection platform;

[0006] The interior of the composite treatment box is equipped with two hollow nozzles and a Y-shaped valve tube. The two hollow nozzles are respectively located on the top outer side and the bottom outer side of one end of the elevator compensation chain. The two end heads at the front end of the Y-shaped valve tube are respectively fixedly sleeved on the inner side of the rear end of the two hollow nozzles. An installation groove is opened in the top of the rear end of the support frame plate. A water pump and a composite control component are installed in the installation groove. The output end of the water pump is connected to a single end of the rear end of the Y-shaped valve tube that passes through the top structure of the composite treatment box. A drainage pipe is installed between the input end of the water pump and the bottom inner side of the composite treatment box.

[0007] Selectedly, auxiliary rollers are movably connected on both sides of the support frame plate, the top surface of the auxiliary rollers is slidingly connected to the surface of the bottom of the elevator compensation chain, and the number of auxiliary rollers is not less than four. Multiple auxiliary rollers are used to improve the smoothness of the sliding flow of the elevator compensation chain on the top surface of the maintenance machine.

[0008] Preferably, the composite control assembly includes a controller, a power module and a remote control module, and the controller is electrically connected to the water pump via a wire.

[0009] Selectedly, a filter plate is sleeved on the inner side of the bottom of the composite treatment box, and the filter plate is composed of a support frame and a filter mesh nested in the support frame. The surface of the support frame is fixedly connected to the inner wall of the bottom of the composite treatment box, and the support frame is fixedly sleeved on one end of the drainage pipe. The filter plate is used to filter the anti-corrosion solution or lubricating oil that is subsequently conditioned and returned to the interior of the composite treatment box.

[0010] Selectedly, auxiliary cleaning components are provided on both sides of the top of the composite processing box, and reflux plates are provided on both sides of the middle part of the composite processing box. The auxiliary cleaning components are composed of a support sleeve, a T-shaped constraint rod, a scraper and a buffer spring.

The elastic movement of the auxiliary cleaning component's own mechanism can scrape and clean the elevator compensation chain without interfering with the movement of the elevator compensation chain, thereby refluxing the excess anti-corrosion solution or lubricating oil attached to the surface of the elevator compensation chain.

[0011] The number of T-shaped constraint rods is the same as the number of buffer springs and both are set to two. The scraper adopts a T-shaped structure, and the bottom of the scraper is a rounded structure. The scraper can elastically press into contact with the elevator compensation chain with the support of the buffer spring, thereby meeting the scraping and cleaning effect of the elevator compensation chain in a moving state.

[0012] Preferably, inclined chutes are provided inside the two reflux plates, and the bottoms of the two inclined chutes are facing the interior of the composite processing box, thereby ensuring that the recovered anti-corrosion solution or lubricating oil can smoothly flow back to the interior of the composite processing box for subsequent continuous use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 A maintenance and inspection device for an elevator includes an inspection platform 1 and an elevator compensation chain 2. A step groove is provided inside the inspection platform 1, in which a support frame plate 3 and a composite processing box 4 are respectively nested. The composite processing box 4 is fixedly sleeved on the inner side of the middle part of the support frame plate 3. Both sides of the middle part of the composite processing box 4 are provided with a clearance groove. One end of the elevator compensation chain 2 passes through the clearance groove and slides on the top surface of the inspection platform 1.

[0025] Auxiliary rollers 10 are movably sleeved on both sides of the support frame 3. The top surface of the auxiliary roller 10 is slidably connected to the bottom surface of the elevator compensation chain 2. The number of auxiliary rollers 10 is not less than four. The use of multiple auxiliary rollers 10 improves the smoothness of the sliding flow of the elevator compensation chain 2 on the top surface of the maintenance platform 1.

[0026] The interior of the composite treatment box 4 is provided with two hollow nozzles 5 and a Y-shaped valve tube 6. The two hollow nozzles 5 are respectively located on the top outer side and the bottom outer side of one end of the elevator compensation chain 2. The two end heads of the front end of the Y-shaped valve tube 6 are respectively fixedly sleeved on the inner side of the rear end of the two hollow nozzles 5. A mounting groove is provided in the top of the rear end of the support frame 3. A water pump 8 and a composite control component 9 are mounted in the mounting groove. The composite control component 9 includes a controller, a power module and a remote control module. The controller is electrically connected to the water pump 8 through a wire. The output end of the water pump 8 is connected to a single end head of the rear end of the Y-shaped valve tube 6 that passes through the top structure of the composite treatment box 4. A drainage pipe 7 is installed between the input end of the water pump 8 and the bottom inner side of the composite treatment box 4.

[0027] The inner side of the bottom of the composite treatment box 4 is sleeved with a filter plate 11, which is composed of a support frame and a filter screen nested in the support frame. The surface of the support frame is fixedly connected to the inner wall of the bottom of the composite treatment box 4, and the support frame is fixedly sleeved with one end of the drainage pipe 7. The filter plate 11 is used to filter the anti-corrosion solution or lubricating oil that is subsequently conditioned and refluxed into the interior of the composite treatment box 4. Auxiliary cleaning components 12 are provided on both sides of the top of the composite treatment box 4, and return plates 13 are provided on both sides of the middle of the composite treatment box 4. The auxiliary cleaning component 12 is composed of a support sleeve 121, a T-shaped constraint rod 122, and a scraper 1 23 and a buffer spring 124. One side of the support sleeve 121 is fixedly connected to the side surface corresponding to the top of the composite processing box 4. One end of the T-shaped constraint rod 122 passes through the support sleeve 121 and is fixedly connected to the top of the scraper 123. The two ends of the buffer spring 124 are respectively fixedly connected to the surface of the other end of the T-shaped constraint rod 122 and the surface of the top of the support sleeve 121. The elastic movement of the auxiliary cleaning component 12 itself can scrape and clean the elevator compensation chain 2 without interfering with the movement of the elevator compensation chain 2, thereby refluxing the excess anti-corrosion solution or lubricating oil attached to the surface of the elevator compensation chain 2;

[0028] The number of T-shaped constraint rods 122 is the same as the number of buffer springs 124 and both are set to two. The scraper 123 adopts a T-shaped structure, and the bottom of the scraper 123 is a rounded structure. The scraper 123 can be elastically pressed into contact with the elevator compensation chain 2 with the support of the buffer spring 124, thereby meeting the scraping and cleaning effect of the elevator compensation chain 2 in a moving state. Inclined chutes are set inside the two return plates 13, and the bottoms of the two inclined chutes are facing the interior of the composite treatment box 4, thereby ensuring that the recovered anti-corrosion solution or lubricating oil can smoothly flow back to the interior of the composite treatment box 4 for subsequent continuous use.

[0029] Working principle:

[0030] Example 1

[0031] For disposable anti-corrosion solutions or lubricating oils, the filter plate 11, the auxiliary cleaning component 12 and the return plate 13 may be omitted. Then, during use, the elevator compensation chain 2, supported by the maintenance machine 1, the auxiliary roller 10 and the existing traction device, passes through the middle inner side of the composite treatment box 4. At the same time, the water pump 8 is turned on by the composite control component 9, and the water pump 8 pumps the pre-placed anti-corrosion solution or lubricating oil at the bottom of the composite treatment box 4 to the Y-type valve tube 6 through the drainage pipe 7. Then, the diversion effect of the Y-type valve tube 6 is utilized to respectively transport the anti-corrosion solution or lubricating oil to the inside of the two hollow nozzles 5. Finally, the two hollow nozzles 5 are used to spray and maintain the elevator compensation chain 2 in a moving state. The liquid flow height can be adjusted by the valve inside the Y-type valve tube 6, thereby meeting the automated maintenance requirements of the elevator compensation chain 2.

[0032] Example 2

[0033] For the recyclable anti-corrosion solution or lubricating oil, a filter plate 11, an auxiliary cleaning component 12 and a return plate 13 are selectively set. Then, during use, the elevator compensating chain 2, supported by the maintenance machine 1, the auxiliary roller 10 and the existing traction device, passes through the middle inner side of the composite processing box 4. At the same time, the water pump 8 is turned on by the composite control component 9, and the water pump 8 pumps the pre-placed anti-corrosion solution or lubricating oil at the bottom of the composite processing box 4 to the Y-type valve tube 6 through the drainage pipe 7. Then, the anti-corrosion solution or lubricating oil is respectively transported to the inside of the two hollow nozzles 5 by utilizing the diversion effect of the Y-type valve tube 6. Finally, the elevator compensating chain 2 in a moving state is sprayed and maintained by the two hollow nozzles 5. The liquid flow height can be adjusted by the valve inside the Y-type valve tube 6, thereby meeting the automated maintenance requirements of the elevator compensating chain 2.

[0034] During the further movement of the elevator compensation chain 2 after spray maintenance, the scraper 123 inside the auxiliary cleaning component 12 will scrape and clean it under the guidance of the T-shaped constraint rod 122 and the elastic support of the buffer spring 124, so that the excess anti-corrosion solution or lubricating oil attached to the surface of the elevator compensation chain 2 will flow into the corresponding return plate 13, and then flow back to the inside of the composite treatment box 4 under the guidance of the return plate 13, and then be reused after filtering treatment by the filter plate 11.
