Description

Technical Field

[0001] The present disclosure relates to the technical field of mine shaft hoisting equipment, and in particular to a hoist wire rope water removal device. Background Art

[0002] During the mine shaft hoisting operation, the wire rope is often soaked by the gushing water or water in the mine. On the one hand, the wet wire rope will increase its own weight, resulting in an increase in the load of the hoisting system and an increase in energy consumption; on the other hand, the presence of water may cause corrosion and rust of the wire rope, accelerate the wear of the wire rope, and reduce its service life. In severe cases, it may even affect the hoisting safety and cause accidents such as rope breaking. In addition, if the wire rope carries water to the equipment, it will corrode the equipment, thereby reducing the service life of the equipment. Summary of the invention

[0003] The purpose of the present disclosure is to provide a device for removing water from a wire rope of a hoist to at least partially solve the problems existing in the related art.

[0004] In order to achieve the above-mentioned purpose, the present disclosure provides a hoist wire rope water removal device, a bracket and a plurality of wiper strips horizontally installed on the bracket, the wiper strips are made of flexible material, and there are gaps between adjacent wiper strips for the wire rope to pass through, and the wire rope is configured to contact the wiper strips when moving.

[0005] Optionally, the width of the gap between adjacent wiper strips is less than or equal to the outer diameter of the steel wire rope.

[0006] Optionally, the wiper strip is made of PET.

[0015] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The accompanying drawings are used to provide a further understanding of the present disclosure and constitute a part of the specification. Together with the following specific embodiments, they are used to explain the present disclosure but do not constitute a limitation of the present disclosure. In the accompanying drawings: Figure 1 is a structural schematic diagram of a hoist wire rope dewatering device provided by an exemplary embodiment of the present disclosure; Figure 2 1 is a top view of a hoist wire rope dewatering device provided in an exemplary embodiment of the present disclosure.

[0017] Description of Reference Numerals 1- bracket; 11- leg; 12- mounting plate; 2- wiper strip; 3- wire rope; 4- drainage trough; 5- water collecting tank DETAILED DESCRIPTION Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying 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.

[0018] In the present disclosure, unless otherwise specified, the directional terms "upper", "lower", "top", and "bottom" used are defined based on the directions in which the relevant components are actually used. "Inside" and "outside" refer to the contours of the corresponding components themselves. In the present disclosure, when the following description refers to the drawings, unless otherwise specified, the same numbers in different drawings represent the same or similar elements.

[0019] In the related art, during the use of mining hoists, since the air in the mine contains a large amount of water vapor, the water vapor will adhere to the surface of the wire rope to form water droplets. The long-term attachment of water droplets to the surface of the wire rope will cause the surface of the wire rope to rust, affecting the service life of the wire rope. In addition, the water brought by the wire rope to the friction wheel will reduce the friction coefficient of the friction wheel, and the water brought by the wire rope to the gate disc will reduce the braking force of the gate disc.

[0020] In view of this, refer to Figure 1 , Figure 2 A first aspect of an embodiment of the present disclosure provides a wire rope dewatering device for a hoist, which may include a bracket 1 and a plurality of wiper strips 2 horizontally mounted on the bracket 1. The wiper strips 2 may be made of a flexible material, and there may be gaps between adjacent wiper strips 2 for the wire rope 3 to pass through. The wire rope 3 may be configured to contact the wiper strips 2 when moving.

[0021] Through the above technical solution, the steel wire rope is driven by the motor to be retracted and released. During the retracting and releasing process, the steel wire rope slides between the multiple wiper strips 2, and the outer surface of the steel wire rope 3 rubs against the side wall of the wiper strip 2 to achieve the effect of removing water stains on the surface of the steel wire rope 3. Eliminating water stains can prevent the steel wire rope 3 from rusting and extend the service life of the steel wire rope 3. The wiper strip 2 made of flexible material can effectively scrape off the residual moisture on the surface of the steel wire rope 3. The hoist steel wire rope water removal device has a simple structure, convenient operation, stable quality, high use efficiency, and easy installation. It can ensure the safety of the use of multi-rope friction wheel hoists and will not corrode hoist equipment.

[0022] Further, refer to Figure 1 , Figure 2 , the width of the gap between adjacent wiper strips 2 can be less than or equal to the outer diameter of the wire rope 3. Specifically, multiple wiper strips 2 are closely arranged so that the wire rope 3 can rub against the side wall of the wiper strip 2 when being retracted and released, so as to scrape off the residual water on the surface of the wire rope 3. Through the above arrangement, the wiper effect is good, the structure is simple, and the cost is low.

[0023] Specifically, the material of the wiper strip 2 can be PET (Polyethylene terephthalate). Specifically, the wiper strip 2 can use PET filaments with smaller diameters. The PET filaments are soft and wear-resistant, will not damage the steel wire rope 3, and have good flexibility and wear resistance, and can effectively scrape off the moisture remaining on the surface of the steel wire rope 3.

[0024] In some embodiments, reference Figure 1The bracket 1 may include a support leg 11 vertically placed on the ground and two mounting plates 12 horizontally mounted on 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 3 vertically passes through the gap between adjacent wiper strips 2, so that the wiper strip 2 has a better wiping effect. In the embodiment of the present disclosure, the wiper strip 2 can be tied between the two mounting plates 12. The present disclosure does not limit the installation method of the wiper strip 2, which belongs to the protection scope of the present disclosure.

[0025] Furthermore, the legs 11 can be fixed to the ground by expansion bolts. The expansion bolts have strong adaptability, are relatively simple to install, are more convenient to use, have a high success rate, can be directly installed by drilling holes, and will not cause problems such as installation tilt. They have strong bearing capacity and are durable.

[0026] As an exemplary embodiment of the present disclosure, water-absorbing sponges can be installed on the side walls of the two mounting plates 12, respectively. The water-absorbing sponges 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 steel wire rope 3 can squeeze the water-absorbing sponge when it moves. The residual moisture on the surface of the steel wire rope 3 will fall onto the water-absorbing sponge after being scraped off by the wiper strip 2. And the water-absorbing sponge abuts against the side wall of the steel wire rope 3. In the process of retracting and releasing the steel wire rope 3, the water-absorbing sponge can further absorb the trace moisture on the steel wire rope 3 after wiping, so that its surface reaches a relatively dry state. In the embodiment 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 to achieve drainage, thereby allowing the water-absorbing sponge to maintain a continuous water absorption capacity.

[0027] Furthermore, the mounting plate 12 may have a cavity, and a side wall of the mounting plate 12 for mounting the water-absorbing sponge is formed with an opening connected to the cavity, and the opening is used to receive water squeezed out of the water-absorbing sponge. The water squeezed out of the water-absorbing sponge by the wire rope 3 can enter the cavity of the mounting plate 12 to avoid water accumulation in the mine.

[0028] In some embodiments, reference Figure 1 The end of the mounting plate 12 may be connected with a drainage groove 4, which is communicated with the cavity. The water scraped by the wiper strip 2 falls to the water-absorbing sponge, is then squeezed into the cavity of the mounting plate 12, and is collected by the drainage groove 4.

[0029] Further, refer to Figure 1 The drainage groove 4 can be arranged to be inclined downward so that the residual water can slide down along the drainage groove 4.

[0030] In some embodiments, reference Figure 1The drainage trough 4 can be connected to the water collecting tank 5. The water scraped by the wiper strip 2 is collected by the drainage trough 4 and introduced into the water collecting tank 5. The water in the water collecting tank 5 can be regularly treated or recycled to avoid water accumulation in the mine and environmental pollution.

[0031] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0033] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
