Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment, and in particular relates to a rope adjusting device for a mine shaft hoist. Background Art

[0002] Mine shaft hoists are the main equipment used to lift ore, coal, personnel, equipment and other materials in underground mine production, and are usually used for vertical material and personnel transportation. The working principle of existing mine shaft hoists is that the lifting container is suspended at both ends of the wire rope, and a balance wire rope is suspended at the bottom of the lifting container. The friction between the wire rope and the friction pad drives the wire rope to move with the friction wheel, thereby realizing the lifting and lowering of the lifting container in the shaft.

[0003] However, existing mine shaft hoisting equipment mostly adopts a multi-rope friction lifting system, that is, multiple steel ropes share the load and use friction to lift heavy objects to the wellhead. Multiple steel ropes work at the same time. Once the length of one of the steel ropes is inconsistent with the length of the other steel ropes, it will cause inconsistent tension between the steel ropes, that is, the length or tension of a certain steel rope deviates from the other steel ropes, resulting in tension imbalance, and even wire rope breakage, equipment damage or safety accidents.

[0036] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0037] In one embodiment, if Figure 1 , Figure 2 and Figure 3As shown, a rope adjusting device for a mine shaft hoist provided by the present invention comprises a base 3, and a rope adjusting mechanism 6, a clamping mechanism 5, a first tension detector 4 and a second tension detector 7 are respectively arranged on one side of the base 3 facing the wire rope 9;

[0038] The clamping mechanism 5 and the first tension detector 4 are respectively arranged in pairs. Along the extension direction of the steel wire rope 9, the clamping mechanisms 5 arranged in pairs are symmetrically arranged on both sides of the rope adjusting mechanism 6. The first tension detectors 4 arranged in pairs are respectively located on the side of the clamping mechanism 5 away from the rope adjusting mechanism 6, and the second tension detector 7 is located between the rope adjusting mechanism 6 and the clamping mechanism 5 on one side.

[0039] The clamping mechanisms 5 arranged in pairs are used to drag the wire rope 9 on one side of the clamping mechanisms 5 away from the rope adjusting mechanism 6 and move toward each other until the tension values ​​of the wire rope 9 detected by the first tension detectors 4 arranged in pairs are consistent. The rope adjusting mechanism 6 is used to abut and adjust the wire rope 9 between the clamping mechanisms 5 arranged in pairs until the tension values ​​of the wire rope 9 detected by the second tension detector 7 and the first tension detector 4 are consistent.

[0040] like Figure 2 As shown, multiple steel wire ropes 9 are respectively passed around the upper wheel 11, the friction wheel 8 and the lower wheel 10 in sequence, and a lifting container (not shown in the figure) is fixedly connected to the traction end of the steel wire rope 9, so that the lifting container can be loaded with goods or take construction personnel into the mine shaft to shift in the vertical shaft direction. When multiple steel wire ropes 9 are working at the same time, if the length of a certain steel wire rope 9 is inconsistent with the length of other steel wire ropes, the rope adjustment device of the present invention can be used to clamp the two positions of the steel wire rope 9 through the clamping mechanism 5 arranged in pairs, such as Figure 2 As shown in the figure, the rope adjusting device is arranged at a position adjacent to the friction wheel 8 to work. At this time, the clamping mechanism 5 divides the steel wire rope 9 to be adjusted into three sections, so that the clamping mechanism 5 drags the steel wire ropes 9 at both ends to move toward each other until the tension values ​​of the steel wire ropes 9 detected by the first tension detectors 4 arranged in pairs are consistent. At this time, the tension of the steel wire ropes 9 between the two groups of clamping mechanisms 5 is very small or even relaxed to no tension. Then, the steel wire ropes 9 between the two groups of clamping mechanisms 5 are tensioned and adjusted separately, and the tensioning and adjusting range is reduced, which greatly reduces the steel wire rope tension. The difficulty of tensioning and adjusting the wire rope 9 is reduced, and during the tensioning and adjusting process, the influence of the fluctuating pulling state of one end of the wire rope 9 pulling the heavy object is avoided, and the tension of the wire rope 9 in the middle section is detected by the second tension detector 7 until the tension values ​​of the wire rope 9 detected by the second tension detector 7 and the first tension detector 4 are consistent, and the rope adjustment operation of the wire rope 9 is completed. At this time, the clamping mechanism 5 and the tension detector are removed, so that the wire rope 9 after tensioning and adjusting is consistent with the length of other wire ropes 9 and the tension meets the working requirements.

[0041] It should be noted that the tension value detected by the first tension detector 4 must meet the working tension value range requirement of the steel wire rope 9 .

[0042] It should be further explained that the types of the first tension detector 4 and the second tension detector 7 can be strain type tension detector, electromagnetic induction type tension detector, vibration type tension detector, piezoelectric sensor type tension detector, optical fiber sensor type tension detector. The staff can choose according to actual needs and perform construction operations according to the corresponding working principle of the selected tension detector. There is no limitation here.

[0043] For example, see Figure 3 , Figure 4 , Figure 5 and Figure 6 The rope adjusting mechanism 6 includes a supporting roller 62, an abutting driving member, an abutting roller 615 and a limiting assembly. The supporting roller 62 is arranged on the base 3. The supporting rollers 62 are arranged in pairs. Along the extension direction of the steel wire rope 9, the paired supporting rollers 62 are respectively located on both sides of the abutting roller 615. The limiting assembly is arranged corresponding to the supporting roller 62. The limiting assembly is used to limit the steel wire rope 9 on the supporting side of the supporting roller 62. The abutting driving member is arranged on the limiting assembly, and the output end of the abutting driving member is transmission-connected with the abutting roller 615. When the limiting assembly is in the limiting position, the abutting driving member is used to drive the abutting roller 615 to switch between the initial position and the abutting position.

[0044] After the paired clamping mechanisms 5 drag the steel wire rope 9 until the tension values ​​of the steel wire rope 9 detected by the paired first tension detectors 4 are consistent, since the steel wire rope 9 between the clamping mechanisms 5 is in a state of very low tension or even relaxation, the steel wire rope 9 is limited on the supporting side of the supporting roller 62 by the limiting assembly, that is, Figure 3 The upper side of the support roller 62 shown in the figure makes it possible for the wire rope 9 to not break away from the support roller 62 when the abutment roller 615 abuts against the wire rope 9. Figure 3 Taking the figure as an example, the dotted line indicates the extended position of the wire rope 9. Under the drive of the abutment driving member, the abutment roller 615 moves downward to abut the wire rope 9, and combined with the double-point support and limiting action of the paired support rollers 62, the tensioning and rope adjustment of the wire rope 9 is achieved.

[0045] For example, see Figure 4 , Figure 5 and Figure 8 The limiting assembly includes a mounting frame 68, a first telescopic member 618, a transmission rod 66 and a limiting rod 64. The mounting frame 68 is fixedly arranged on the base 3 through a support column 67. The first telescopic member 618 is arranged in the mounting frame 68. Figure 8As shown, the first telescopic member 618 is fixedly arranged in the mounting frame 68 through the mounting seat 619, the output end of the first telescopic member 618 is fixedly connected with the shift block 69, and the mounting frame 68 is provided with a through slot 6181, so that the shift block 69 can enter and exit the mounting frame 68 through the through slot 6181, and the side end of the shift block 69 is fixedly connected with the cantilever 65, and the end of the cantilever 65 away from the shift block 69 is rotatably connected to one end of the transmission rod 66, and the other end of the transmission rod 66 is rotatably connected to one end of the active rod 642, and the other end of the active rod 642 is fixedly connected to one end of the limit rod 64, that is, the active rod 642 and the limit rod 64 form an L-shaped structure, and the fixed connection position of the active rod 642 and the limit rod 64 is rotatably connected to the limit seat 643, and the limit seat 643 is fixedly arranged on the mounting frame 68;

[0046] The limiting rods 64 corresponding to the same supporting roller 62 are arranged in pairs. When the displacement block 69 moves downward from the initial position toward the direction close to the base 3 to the maximum displacement position under the drive of the first telescopic member 618, the cantilever 65 drives the transmission rod 66 to move downward, so that the transmission rod 66 drives the active rod 642 to swing. Figure 8 As shown, taking the limit rod 64 on the left side as an example, the limit rod 64 swings counterclockwise, and the limit rods 64 arranged in pairs swing to the front and rear side positions of the support roller 62 respectively, and the lower end position of the limit rod 64 is lower than the upper end position of the support surface of the support roller 62, thereby constraining the wire rope 9 between the limit rods 64 and the support roller 62 symmetrically arranged on the front and rear sides, preventing the wire rope 9 from detaching from the support roller 62 when the subsequent abutment roller 615 abuts and tensions the wire rope 9.

[0047] For example, see Figure 4 and Figure 5 The support roller 62 is rotatably connected to the first support plate 63, the first support plate 63 is fixedly arranged on the first bracket 61, the first bracket 61 is fixedly arranged on the base 3, the first support plate 63 is provided with a limiting groove 631, and the other end of the limiting rod 64 is fixedly provided with a limiting block 641. When the limiting rods 64 arranged in pairs swing to the front and rear side positions of the support roller 62 respectively, the limiting block 641 swings synchronously with the limiting rod 64 to the limiting groove 631, so that the limiting rod 64 fully swings to the limiting position, and with the help of the abutment between the limiting block 641 and the groove wall of the limiting groove 631, the lateral extrusion of the limiting rod 64 by the wire rope 9 is avoided, causing the limiting rod 64 to separate from the first support plate 63 along the axial center line direction of the support roller 62.

[0048] For example, see Figure 7 and Figure 8The abutment driving member includes a second telescopic member 617, a second bracket 616 and a second support plate 614. The second telescopic member 617 is arranged in the shift block 69. The output end of the second telescopic member 617 is fixedly connected to the second bracket 616. One end of the second bracket 616 located outside the shift block 69 is fixedly connected to the second support plate 614. The abutment roller 615 is rotatably connected to the second support plate 614. Therefore, under the drive of the second telescopic member 617, the second bracket 616 drives the abutment roller 615 to move down to the abutment position through the second support plate 614, so as to achieve abutment tensioning of the steel wire rope 9 located between the clamping mechanism 5.

[0049] It should be noted that if Figure 5 and Figure 7 As shown, the circumferential side walls of the support roller 62 and the abutment roller 615 are both provided with arc grooves, which increase the abutment contact surface of the support roller 62 and the abutment roller 615 on the wire rope 9, and help the wire rope 9 to move along the abutment contact surface of the support roller 62 and the abutment roller 615 when the wire rope 9 is subsequently used to lift the goods, so that the support roller 62 and the abutment roller 615 rotate respectively, thereby greatly reducing the friction resistance encountered by the wire rope 9 when pulling the goods.

[0050] For example, see Figure 6 The rope adjusting mechanism 6 also includes a gathering component, which is arranged on one side of the abutment roller 615 , and the gathering component is used to gather the wire rope 9 between the paired support rollers 62 to the abutment side of the abutment roller 615 .

[0051] Continue reading Figure 6 and Figure 7 The folding assembly includes an abutment plate 610, a spring 611 and a side plate 612. The lower end of the shift block 69 is fixedly provided with an abutment plate 610, and the abutment plate 610 is located between the abutment roller 615 and the shift block 69. The side end of the second support plate 614 is rotatably connected with a rotating block 613, and the rotating block 613 is fixedly provided on the side plate 612. Along the axial center line direction of the abutment roller 615, the side plates 612 are symmetrically arranged front and back, and the paired side plates 612 are fixedly connected by springs 611.

[0052] In the above embodiment, after the limiting rod 64 swings to the limiting position, before the contact roller 615 moves down to perform the contact operation, Figure 6As shown, the abutment plate 610 abuts against the spring 611, and the spring 611 pulls the upper ends of the side plates 612 closer to each other, so that the distance between the lower ends of the side plates 612 is maximized, and even if the wire rope 9 between the support rollers 62 is laterally relaxed and bent, for example, relaxed and bent toward the front side or the rear side, the wire rope 9 can be limited between the side plates 612 by means of the large opening size at the lower end of the side plates 612, and under the drive of the second telescopic member 617, the abutment roller 615 moves downward, so that during the downward movement of the side plate 612, the abutment plate 610 releases the abutment constraint on the spring 611, and under the action of the elastic force of the spring 611, the opening size of the lower end of the side plate 612 is gradually reduced, thereby bringing the wire rope 9 toward the middle of the abutment roller 615, and finally achieving the abutment roller 615 abutting the wire rope 9 in the center.

[0053] Continue reading Figure 3 and Fig. 9 The clamping mechanism 5 includes a dragging assembly and a clamping assembly. The dragging assembly includes a motor 583, a screw 581, a slide rail 582 and a slider 58. The slide rail 582 is fixedly arranged on the base 3. The slider 58 is slidably connected in the slide rail 582. The slider 58 is threadedly connected to the screw 581. Both ends of the screw 581 are rotatably connected to the slide rail 582. The input end of the screw 581 is transmission-connected to the motor 583.

[0054] The slider 58 is fixedly connected to a support seat 53, and the clamping assembly includes a third telescopic member 51, a driving rod 52, a rocker rod 55 and a clamping rod 56. The third telescopic member 51 is fixedly set on the support seat 53, and the output end of the third telescopic member 51 is fixedly connected to the driving rod 52, the driving rod 52 penetrates the frame 54 and is slidably connected to the frame 54, and the frame 54 is fixedly set on the support seat 53. The outer end of the driving rod 52 is fixedly connected to a fixed block 57, and the side end of the fixed block 57 is rotatably connected to the rocker rod 55, and the other end of the rocker rod 55 is rotatably connected to the clamping rod 56, and the middle part of the clamping rod 56 is rotatably connected to the frame 54, and a clamping block 561 is fixedly set on the end of the clamping rod 56 away from the rocker rod 55, wherein the rocker rod 55 is arranged in pairs, and the clamping rod 56 and the rocker rod 55 are arranged correspondingly.

[0055] In the above embodiment, when the steel wire rope 9 is clamped and dragged at two points, the driving rod 52 is driven to move outward by the third telescopic member 51, thereby driving the clamping rod 56 to clamp and move through the rocker arm 55, so that the clamping block 561 clamps and fixes the steel wire rope 9, and then the two motors 583 are started, so that the slider 58 drives the clamping assembly on the support seat 53 to move toward the direction close to the abutment roller 615, so that the steel wire rope 9 on the side of the clamping assembly away from the abutment roller 615 is tightened until the tension of the steel wire rope 9 meets the tension requirement.

[0056] For example, see Figure 1 and Fig.10 A positioning mechanism 2 is provided on one side of the base 3 away from the rope adjusting mechanism 6, and an output end of the positioning mechanism 2 is transmission-connected to the base 3, and the positioning mechanism 2 is used to adjust the position between the rope adjusting mechanism 6 and the wire rope 9 through the base 3;

[0057] The positioning mechanism 2 includes a trolley 1, a lifting and adjusting component and an angle adjusting component. The lifting and adjusting component is arranged on the trolley 1.
