Description

Technical Field

[0001] The utility model relates to the technical field of scraper cables, in particular to a scraper cable anti-wear device for a cable well. Background Art

[0002] A scraper is a transport machine used in coal mining. Since the scraper blade is driven by electric energy, the scraper is powered by cables laid in the cable well.

[0003] However, during the movement of the scraper, the scraper drags the cable and the cable moves along the cable well. During the movement of the cable, friction occurs between the cable and the ground and the wall of the cable well. Due to the rough surface of the ground and the wall of the cable well, and the high frequency of friction between the ground and the wall of the cable well and the cable, the cable is easily damaged.

[0004] If the cable is not handled in time after being worn, it will easily lead to a short circuit. Therefore, the cables on the scraper need to be inspected regularly by humans, and the damaged cables need to be wrapped, which leads to high intensity of work in maintaining the scraper cables.

[0006] The present application provides a cable well scraper cable wear prevention device adopts the following technical solution:

[0007] A cable wear prevention device for a scraper machine for a cable well comprises a support frame, a guide seat is arranged between the support frames, a guide through hole is provided on the guide seat, the guide through hole is for the cable to be inserted, an anti-wear component is arranged in the guide through hole, the anti-wear component is used to reduce the friction between the cable and the guide seat, a left support seat is arranged at one end of the support frame, a plurality of left support rollers are rotatably arranged on the left support seat, a right support seat is arranged at the other end of the support frame, a plurality of right support rollers are rotatably arranged on the right support seat, and the left support rollers and the right support rollers are both used to support the cable.

[0008] By adopting the above technical scheme, the support frame is installed on the steel structure of the cable well so that the support frame is located above the cable well, the left support seat is installed on the ground on one side of the cable well mouth, and the right support seat is installed on the ground on the other side of the cable well mouth. The cable in the cable well passes through the guide through hole and is connected to the scraper. When the scraper is located on the side where the left support seat is away from the right support seat, the cable is supported by the left support roller. When the scraper is located on the side where the right support seat is away from the left support seat, the cable is supported by the right support roller. When the scraper moves, the scraper drives the cable to move, and the cable in the cable well moves along the guide through hole. The guide through hole limits the cable, so that the cable is not easy to rub against the inner wall of the cable well. At the same time, the anti-wear component reduces the friction between the cable and the guide seat, and the cable located on the ground moves along the left support roller or the right support roller, and the left support roller or the right support roller supports the cable, thereby making it difficult for the cable to rub against the ground, thereby achieving the effect of reducing the wear of the scraper cable and reducing the work intensity of maintaining the scraper cable.

[0015] Preferably, a concave surface is provided on the outer wall of the left support roller and the outer wall of the right support roller.

[0016] By adopting the above technical solution, the left support roller and the right support roller form a structure in which the middle diameter is smaller than the diameter at both ends. Therefore, when the cable is located on the left support roller and the right support roller, the cable is made to move along the center end of the left support roller and the right support roller, thereby reducing the possibility of the cable falling off the left support roller and the right support roller.

[0017] Preferably, a left connecting shaft is rotatably arranged on the end wall of the left support roller, and a plurality of groups of left connecting grooves are provided on the top wall of the left support seat.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application discloses a cable wear prevention device for a cable well scraper. Figures 1 to 3, which includes a support frame 1, which is installed on the steel structure of the cable well, and the support frame 1 is located directly above the wellhead of the cable well. A guide seat 2 is installed between the support frames 1, and a guide through hole 21 is provided through the center of the guide seat 2 along the height direction. The guide through hole 21 is for the cable to pass through. The cable in the cable well passes through the guide through hole 21 and is connected to the scraper. An anti-wear component 3 is installed in the guide through hole 21, and the anti-wear component 3 is used to reduce the friction between the cable and the guide seat 2. A left support seat 4 is provided at one end of the support frame 1. The left support seat 4 is a concave structure. The left support seat 4 is installed on the ground on one side of the wellhead of the cable well. Three left support rollers 41 are rotatably installed on the left support frame 1. The left support rollers 41 are arranged along the width direction, and the height of the left support rollers 41 is higher than the height of the guide seat 2. A right support seat 5 is provided at the other end of the support frame 1. The right support seat 5 is a concave structure. The right support seat 5 is installed on the ground on the other side of the wellhead of the cable well. Three right support rollers 51 are rotatably mounted on the right support frame 1. The right support rollers 51 are arranged along the width direction, and the height of the right support rollers 51 is higher than the height of the guide seat 2. The left support rollers 41 and the right support rollers 51 are located at the same height, and the left support rollers 41 and the right support rollers 51 are symmetrically installed at both ends of the support frame 1. The left support rollers 41 and the right support rollers 51 are both used to support cables. When the scraper moves, the scraper drives the cable to move, and the cable in the cable well moves along the guide through hole 21. The guide through hole 21 limits the cable so that the cable is not easy to rub against the inner wall of the cable well. At the same time, the anti-wear component 3 reduces the friction between the cable and the guide seat 2. When the scraper is located on the side of the left support seat 4 away from the right support seat 5, the cable on the ground moves along the left support roller 41, and the cable is supported by the left support roller 41, so that the cable is not easy to rub against the ground. When the scraper is located on the side of the right support seat 5 away from the left support seat 4, the cable on the ground moves along the right support roller 51, and the right support roller 51 supports the cable so that the cable is not easy to rub against the ground. Through the mutual cooperation of the guide seat 2, the left support roller 41 and the right support roller 51, the effect of reducing the wear of the scraper cable is achieved, and the work intensity of maintaining the scraper cable is reduced.

[0035] In order to reduce the friction between the cable and the guide seat 2, refer to Figure 2 and Figure 3The anti-wear assembly 3 includes a group of transverse rollers 31 and a group of longitudinal rollers 32. The ends of the transverse rollers 31 and the longitudinal rollers 32 are rotatably connected to the inner wall of the guide through hole 21. The transverse rollers 31 are symmetrically arranged in the guide through hole 21. The transverse rollers 31 are arranged along the length direction of the guide seat 2, and the left support rollers 41 and the right support rollers 51 are perpendicular to the transverse rollers 31. The longitudinal rollers 32 are symmetrically arranged in the guide through hole 21. The longitudinal rollers 32 are arranged along the width direction of the guide seat 2, and the left support rollers 41 and the right support rollers 51 are perpendicular to the longitudinal rollers 32. The transverse rollers 31 and the longitudinal rollers 32 are located at the same horizontal height, and the heights of the transverse rollers 31 and the longitudinal rollers 32 are lower than the heights of the left support rollers 41 and the right support rollers 51. A channel for the cable to pass through is formed between the transverse rollers 31 and the longitudinal rollers 32. The cable passes through between the transverse rollers 31 and the longitudinal rollers 32. When the cable moves, the transverse rollers 31 and the longitudinal rollers 32 rotate. The transverse roller 31 and the longitudinal roller 32 convert the sliding friction between the cable and the guide seat 2 into rolling friction, thereby reducing the friction between the cable and the guide seat 2 and further reducing the wear of the scraper cable.

[0036] To reduce cable sag, refer to Figures 1 to 3 A set of slide rails 6 are installed along the length direction of the support frame 1, and the slide rails 6 are arranged opposite to each other. A slider 61 is slidably arranged inside the slide rail 6, and the opposite surface of the slider 61 is welded to the side wall of the guide seat 2. The guide seat 2 moves along the slide rail 6 through the slider 61, and then the guide seat 2 moves along the length direction of the support frame 1, so as to achieve the effect of changing the distance between the guide seat 2 and the left support seat 4, and to achieve the effect of changing the distance between the guide seat 2 and the right support seat 5. When the scraper drives the cable located on the left support roller 41 to move onto the right support roller 51, the cable pulls the guide seat 2 to move, so that the guide seat 2 is away from the left support seat 4 and close to the right support seat 5, thereby reducing the distance between the guide seat 2 and the right support seat 5, so that the cable between the guide through hole 21 and the right support roller 51 is not easy to be sunken. When the scraper drives the cable on the right support roller 51 to move toward the left support roller 41, the cable pulls the guide seat 2 to move, so that the guide seat 2 moves away from the right support seat 5 and approaches the left support seat 4, thereby reducing the distance between the guide seat 2 and the left support seat 4, making it difficult for the cable between the guide through hole 21 and the left support roller 41 to sag. This reduces the friction between the cable and the wall of the cable well caused by the sag of the cable, thereby reducing the wear of the scraper cable.

[0037] In order to reduce the situation that the cable falls off the left support roller 41 and the right support roller 51, refer to Figure 4 and Figure 5The outer walls of the left support roller 41 and the outer walls of the right support roller 51 are both provided with concave surfaces 7, so that the middle diameter of the left support roller 41 is smaller than the diameters at both ends of the left support roller 41, and the middle diameter of the right support roller 51 is smaller than the diameters at both ends of the right support roller 51. When the cable is located on the left support roller 41 and the right support roller 51, the cable is moved along the center end of the left support roller 41 and the right support roller 51 to reduce the situation where the cable falls off the left support roller 41 and the right support roller 51.

[0038] In order to symmetrically install the left support roller 41 and the right support roller 51 on the ground at both sides of the cable well opening, refer to Figures 1 to 5 , a plurality of fixing holes 81 are provided on the left support seat 4 and the right support seat 5, and anchor bolts 8 are arranged in the fixing holes 81. Three groups of left connecting grooves 43 are provided on the top wall of the left support seat 4, and the left connecting grooves 43 penetrate the side wall of the left support seat 4 along the width direction. The left connecting shaft 42 is inserted in the left connecting groove 43, and the opposite surface of the left connecting shaft 42 is rotatably connected to the left support roller 41. Three groups of right connecting grooves 53 are provided on the top wall of the right support seat 5, and the right connecting groove 53 penetrates the side wall of the right support seat 5 along the width direction. The right connecting shaft 52 is inserted in the right connecting groove 53, and the opposite surface of the right connecting shaft 52 is rotatably connected to the right support roller 51. The anchor bolts 8 penetrate the fixing holes 81 and are threadedly connected to the ground, so that the left support seat 4 and the right support seat 5 are installed on the ground on both sides of the wellhead of the cable well. The left connecting shaft 42 is inserted in the left connecting groove 43, so that the left support roller 41 is rotatably installed on the left support seat 4, and it is convenient to replace and disassemble the left support roller 41 on the left support seat 4. The right connecting shaft 52 is inserted into the right connecting groove 53 , so that the right supporting roller 51 is rotatably installed on the right supporting seat 5 , and the right supporting roller 51 on the right supporting seat 5 is easily replaced and disassembled.

[0039] The implementation principle of the cable wear prevention device for a cable well scraper in the embodiment of the present application is as follows: the guide seat 2 is installed on the steel structure of the cable well through the support frame 1, and the left support roller 41 and the right support roller 51 are symmetrically installed on the ground on both sides of the wellhead of the cable well. The cable in the cable well is connected to the scraper after being passed between the transverse roller 31 and the longitudinal roller 32. When the scraper is located on the side of the left support seat 4 away from the right support seat 5, the cable is supported by the left support roller 41, and when the scraper is located on the side of the right support seat 5 away from the left support seat 4, the cable is supported by the right support roller 51. In the process of the scraper driving the cable to move, the cable in the cable well moves along the guide through hole 21, and the guide through hole 21 limits the cable, so that the cable is not easy to rub against the inner wall of the cable well, and at the same time, the transverse roller 31 and the longitudinal roller 32 reduce the friction between the cable and the guide seat 2. The cable on the ground is supported by the left support seat 4 or the right support roller 51, so that the cable is not easy to rub against the ground. The effect of reducing the wear of the scraper cable is achieved, and the work intensity of maintaining the scraper cable is reduced.
