[0021] The exemplary embodiments will be described in detail herein, with examples shown in the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0022] In the present disclosure, the orientation words "upper", "lower", "top", "bottom" are defined based on the actual direction of use of the relevant components. "Inner", "outer" is in relation to the contour of the respective component itself. In the present disclosure, the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0023] In the related art, during use of the mine hoist, because the air in the mine contains a large amount of water vapor, the water vapor will adhere to the surface of the steel wire rope, forming water droplets. Long-term adhesion of the water droplets to the surface of the steel wire rope will cause rusting of the surface of the steel wire rope, affecting the service life of the steel wire rope. Moreover, the water carried by the steel wire rope to the friction wheel will reduce the friction coefficient of the friction wheel, and the water carried by the steel wire rope to the brake disc will reduce the braking force of the brake disc.
[0024] In view of this, with reference to Figure 1 , Figure 2 , a first aspect of the embodiments of the present disclosure provides a steel wire rope water removal device for a hoist, which can include a support 1 and a plurality of water scraping strips 2 horizontally installed on the support 1. The water scraping strips 2 can be made of a flexible material, and have gaps between adjacent water scraping strips 2 for the steel wire rope 3 to pass through. The steel wire rope 3 can be configured to be in contact with the water scraping strips 2 when moving.
[0025] Through the above technical solution, the steel wire rope is retracted and extended by the motor. During the retraction and extension process, the steel wire rope slides between the plurality of water scraping strips 2. Through the friction between the outer surface of the steel wire rope 3 and the side wall of the water scraping strip 2, the effect of removing water stains on the surface of the steel wire rope 3 is achieved. Elimination of water stains can prevent rusting of the steel wire rope 3 and prolong the service life of the steel wire rope 3. The water scraping strips 2 made of a flexible material can effectively scrape off the residual water on the surface of the steel wire rope 3. The steel wire rope water removal device for the hoist has simple structure, convenient operation, stable quality, high use efficiency, easy installation, and can ensure the safety of the multi-rope friction wheel hoist in use, without corroding the hoist equipment.
[0026] Further, with reference to Figure 1 , Figure 2 , the width of the gap between adjacent water scraping strips 2 can be less than or equal to the outer diameter of the steel wire rope 3. Specifically, the plurality of water scraping strips 2 are closely arranged, so that the steel wire rope 3 can generate friction with the side wall of the water scraping strip 2 when retracted and extended, to scrape off the residual water on the surface of the steel wire rope 3. Through the above arrangement, the scraping effect is good, and the structure is simple and low in cost.
[0027] Specifically, the material of the wiper strip 2 can be PET (Polyethylene terephthalate). Specifically, the wiper strip 2 can be made of PET filaments with small diameters. The PET filaments are soft and wear-resistant, and will not damage the steel wire rope 3. In addition, the PET filaments have good flexibility and wear resistance, and can effectively wipe off the water on the surface of the steel wire rope 3.
[0028] In some embodiments, with reference to Figure 1 , the support 1 can include a support leg 11 vertically placed on the ground and two mounting plates 12 horizontally mounted at the top of the support leg 11, and the wiper strip 2 is vertically mounted between the two mounting plates 12. In this way, the steel wire rope 3 passes through the gap between adjacent wiper strips 2, so that the wiper effect of the wiper strip 2 is better. In the embodiments of the present disclosure, the wiper strip 2 can be tied between the two mounting plates 12. The present disclosure does not limit the mounting method of the wiper strip 2, which belongs to the protection scope of the present disclosure.
[0029] Further, the support leg 11 can be fixedly mounted to the ground by expansion bolts. The expansion bolts have strong adaptability, simple installation, convenient use, high success rate, and can be directly installed by drilling holes without tilting during installation. In addition, the expansion bolts have strong load-bearing capacity and are durable.
[0030] As an exemplary embodiment of the present disclosure, a water-absorbing sponge can be mounted on the side wall of each of the two mounting plates 12. The water-absorbing sponge can be placed between the two mounting plates 12 and below the wiper strip 2. The end of the water-absorbing sponge away from the mounting plate 12 abuts against the side wall of the steel wire rope 3, so that the water-absorbing sponge can be squeezed when the steel wire rope 3 moves. After the water on the surface of the steel wire rope 3 is wiped off by the wiper strip 2, the water will fall onto the water-absorbing sponge. In addition, the water-absorbing sponge abuts against the side wall of the steel wire rope 3, and during the process of winding and unwinding the steel wire rope 3, the water-absorbing sponge can further absorb the small amount of water on the steel wire rope 3 after wiping, so that the surface of the steel wire rope 3 reaches a relatively dry state. In the embodiments of the present disclosure, when the water-absorbing sponge abuts against the side wall of the steel wire rope 3, the water-absorbing sponge is in a compressed state, and the steel wire rope 3 can squeeze the water-absorbing sponge when it moves, so as to realize water drainage, and further maintain the continuous water-absorbing capacity of the water-absorbing sponge.
[0031] Further, the mounting plate 12 can have a cavity, and the side wall of the mounting plate 12 for mounting the water-absorbing sponge is formed with an opening communicating with the cavity. The opening is used to receive the water squeezed out of the water-absorbing sponge. The water squeezed out of the water-absorbing sponge after being squeezed by the steel wire rope 3 can enter the cavity of the mounting plate 12, so as to avoid causing water accumulation in the mine.
[0032] In some embodiments, with reference to Figure 1The end of the mounting plate 12 can be connected with a drain groove 4 which is communicated with the cavity. The water scraped by the wiper strip 2 falls to the water-absorbing sponge and is then squeezed into the cavity of the mounting plate 12 and collected through the drain groove 4.
[0033] Further, referring to Figure 1 The drain groove 4 can be arranged downwardly inclined to facilitate the residual water to slide downwardly along the drain groove 4.
[0034] In some embodiments, referring to Figure 1 The drain groove 4 can be connected to a water collecting tank 5. The water scraped by the wiper strip 2 is collected through the drain groove 4 and then introduced into the water collecting tank 5. The water in the water collecting tank 5 can be treated or recycled regularly to avoid causing water accumulation in the mine and environmental pollution.
[0035] The preferred embodiments of the present disclosure are described in detail above with reference to the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
[0036] In addition, it should be noted that each specific technical feature described in the above-described specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0037] In addition, various different embodiments of the present disclosure can also be combined in any manner as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
