DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The utility model provides a technical scheme:

[0027] Please refer to Figures 1 to 4 A kind of anti jamming guide device of elevator compensating chain, including guide support assembly 1, the inside of guide support assembly 1 is detachably connected with guide wheel assembly 4, the both ends of guide wheel assembly 4 are provided with adjusting assembly 2, and the inside of guide support assembly 1 is provided with lubricating assembly 3;

[0028] Guide support assembly 1 includes support body 101, the bottom of support body 101 is fixed with connecting support 104 for installing guide support assembly 1 in elevator shaft interior;

[0029] The lubrication component 3 includes a limiting groove 304 formed on the inner wall of the support body 101, and a limiting slider 303 is slidably connected inside the limiting groove 304. A lubricant housing 302 is fixedly connected to one side of the limiting slider 303, and a solid lubricant 301 is fixedly filled on the side of the lubricant housing 302 near the guide wheel assembly 4. The lubricant housing 302 is snapped into the support body 101 through the limiting slider 303 and the limiting groove 304. In order to better fix the lubrication component 3, a magnet can be used at the bottom of the lubricant housing 302. The connection between the support body 101 and the lubricant housing 302 can be made of materials such as iron, cobalt, and nickel, so that the lubricant housing 302 can be adsorbed on the support body 101. The solid lubricant 301 can be a solid lubricant such as graphite.

[0030] By adopting the above technical solution, the main body 101 of the bracket can be fixedly installed in the elevator shaft through the connecting bracket 104. The elevator compensation chain passes through the guide wheel assembly 4. Since a solid lubricant 301 is provided on one side of the guide wheel assembly 4, when the guide wheel assembly 4 rotates with the elevator compensation chain, it can come into contact with the solid lubricant 301, thereby applying lubricant to the surface of the guide wheel assembly 4. This lubricates the guide wheel assembly 4, reduces the friction between the guide wheel assembly 4 and the elevator compensation chain, thus reducing wear and noise to a certain extent, and extending the service life of the guide wheel assembly 4. Furthermore, the solid lubricant... After lubricant 301 is used up, the lubricant housing 302 can slide inside the limiting groove 304 via the limiting slider 303, making it easy to disassemble the lubricant housing 302 and replace it with a new solid lubricant 301. When the solid lubricant 301 comes into contact with the guide wheel assembly 4, it applies lubricant to the surface of the guide wheel assembly 4, thus lubricating the guide wheel assembly 4 and reducing the friction between the guide wheel assembly 4 and the elevator compensation chain. There is no need to manually apply lubricant, making it convenient to use. The solid lubricant 301 is directly set on the lubricant housing 302, which can meet the needs of multiple lubrication operations and extend the interval between maintenance personnel going down into the well.

[0031] Specifically, such as Figure 4 As shown, the guide wheel assembly 4 includes a guide wheel body 401 disposed on one side of the lubricant housing 302, and a support rod 403 passing through the inside of the guide wheel body 401. A connecting bearing 404 is installed between the support rod 403 and the guide wheel body 401. An L-shaped mounting groove 102 is provided at the connection between the support rod 403 and the bracket body 101, and a mounting nut 402 is threadedly connected to the surface of the support rod 403. The mounting nut 402 fits into the L-shaped mounting groove 102. A fixed base 103 is fixed around the bracket body 101, and the fixed base 103 is adapted to the position of the adjustment assembly 2.

[0032] The adjustment assembly 2 includes an adjustment screw 202 that is connected to the support rod 403 via a screw sleeve. One end of the adjustment screw 202 is fixedly connected to a transmission motor 204. The adjustment assembly 2 also includes a fixing plate 201 that is fixedly connected to the transmission motor 204 on one side of the fixed base 103. The fixing plate 201 is internally threaded with a fixing screw 203. The adjustment screw 202 is rotatably mounted on another set of fixing plates 201.

[0033] By adopting the above technical solution, the support rod 403 can be installed on the bracket body 101 through the L-shaped mounting groove 102. When it is necessary to adjust the position of the support rod 403, the transmission motor 204 can be started. The transmission motor 204 drives the adjusting screw 202 to rotate. The adjusting screw 202 is a double-acting screw. Under the action of the screw sleeve, it can drive the two sets of support rods 403 to move in opposite directions on the adjusting screw 202, thereby adjusting the distance between the two sets of support rods 403. This facilitates the adjustment of the distance between the solid lubricant 301 and the guide wheel body 401. The use of solid lubricant 301 increases the distance between solid lubricant 301 and guide wheel body 401, which allows for adjustment of the position of guide wheel body 401 and facilitates lubrication of guide wheel body 401. After lubrication, the position of guide wheel body 401 can be reset. Through the set adjustment component 2, the distance between guide wheel bodies 401 can be adjusted under the action of transmission motor 204, so that solid lubricant 301 and guide wheel body 401 are brought closer to each other during lubrication, which facilitates lubrication of guide wheel body 401.

[0034] Working principle: The main body 101 of the support frame can be fixedly installed in the elevator shaft through the connecting bracket 104. The elevator compensation chain passes between the guide wheel assemblies 4. Since solid lubricant 301 is provided on one side of the guide wheel assembly 4, when it is necessary to adjust the position of the support rod 403, the transmission motor 204 can be started. The transmission motor 204 drives the adjusting screw 202 to rotate. The adjusting screw 202 is a double-acting screw. Under the action of the screw sleeve, it can drive the two sets of support rods 403 to move in opposite directions on the adjusting screw 202, thereby adjusting the distance between the two sets of support rods 403. This facilitates the adjustment of the distance between the solid lubricant 301 and the guide wheel main body 401. With the use of solid lubricant 301, the solid lubricant... The increased distance between the lubricant 301 and the guide wheel body 401 allows for adjustment of the guide wheel body 401's position. The guide wheel body 401 and the solid lubricant 301 come into contact, thus applying lubricant to the surface of the guide wheel assembly 4, lubricating it and reducing friction between the guide wheel assembly 4 and the elevator compensation chain. This reduces wear and noise, extends the service life of the guide wheel assembly 4, and after the solid lubricant 301 is used up, the lubricant housing 302 can slide within the limiting groove 304 via the limiting slider 303, facilitating disassembly of the lubricant housing 302 and replacement with new solid lubricant 301.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
