Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a testing device for rope wheels of a mining hoist. Background Technology

[0002] Rope pulleys are one of the most important components in hoisting equipment. Chains or ropes are usually wound around the pulley to lift or lower goods or personnel. Therefore, the quality of the rope pulley determines the safety of goods and personnel transportation.

[0003] Therefore, rope pulleys need to be inspected for quality during production and after prolonged use to check for problems such as bulges or cracks.

[0004] Traditional methods for inspecting mine hoist sheaves rely heavily on manual inspection. This method is not only inefficient but also has limited accuracy, failing to meet the high maintenance requirements of modern mining. Furthermore, manual inspection poses safety hazards, as personnel must approach the high-speed rotating sheaves, undoubtedly increasing operational risks. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a testing device for the rope wheel of a mining hoist, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detection device for a mine hoist sheave includes a base and a slide rail laid horizontally on the upper part of the base. A baffle is provided in the middle of the slide rail, and a slide rail extends from one end of the baffle. Positioning blocks that are slidably connected to the slide rail are provided on both sides of the baffle. A drive shaft is rotatably embedded in the upper end of each of the two positioning blocks. A clamping block is provided at the opposite end of each of the two drive shafts. A first support rod is slidably arranged on the slide rail. A second support rod is rotatably connected to the upper end of the first support rod. The second support rod extends between the two clamping blocks. A jump sensor counter is fixedly connected to the end of the second support rod that is placed between the clamping blocks.

[0008] Furthermore, the slide rail is continuously laid from left to right along the upper surface of the base and protrudes from the upper surface of the base. A T-shaped sliding hole is opened laterally in the middle of the slide rail, and the positioning block is slidably connected through the sliding hole in the middle of the slide rail.

[0009] Furthermore, the bottom of the positioning block has a groove corresponding to the slide rail protrusion structure, and a T-shaped clip corresponding to the T-shaped sliding hole protrudes from the middle of the groove. The positioning block is slidably connected through the groove and the T-shaped clip corresponding to the slide rail and the T-shaped sliding hole, respectively.

[0010] Furthermore, the upper end of the positioning block is horizontally supported by a tube support with openings at both ends and a hollow interior. The drive shaft is rotatably nested inside the tube support, and one end of the drive shaft is coaxially connected to a motor.

[0011] Furthermore, the outer circumference of the clamping block has multiple fixed tubes with open tops and hollow interiors. Each fixed tube is fitted with a top block. The fixed tubes are evenly distributed with first positioning holes, and the top blocks are correspondingly provided with multiple second positioning holes. Positioning pins are provided between the first positioning holes and the second positioning holes.

[0012] Furthermore, the slide rail is a U-shaped structural plate.

[0013] Furthermore, a fixing block is provided at the bottom of the first support rod, the first support surface has threads, a nut is threadedly connected to the first support rod, and the first support rod is clamped on the slide rail by the fixing block and the nut.

[0014] Furthermore, the first support rod and the second support rod are fixed together by a connector, which is two block-shaped structures that can be twisted relative to each other and are fixedly connected by a shaft. The second support rod is fixedly connected to the jump sensor counter by the connector.

[0015] Furthermore, the bounce sensor counter has a structure with a pulley at the lower end and a counter at the upper end.

[0016] The beneficial effects of this utility model are as follows:

[0017] During use, this invention uses a speed-up mechanism on the upper drive shaft of the positioning block to clamp the rope wheel to be tested. The drive shaft rotates after the clamping block has clamped the rope wheel. During rotation, a jump sensor counter is attached to the surface of the rope wheel to be tested. When the rope wheel encounters cracks or minor scratches on the surface, the jump sensor counter will jump and provide feedback, thus providing a prompt for maintenance personnel to repair the jumping area. This makes the invention more convenient to use. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1As shown, this utility model provides a detection device for a mine hoist rope sheave, including a base 1 and a slide rail 101 laid horizontally on the upper end of the base 1. A baffle 103 is provided in the middle of the slide rail 101, and a slide rail 5 extends from one end of the baffle 103. The slide rail 5 is a U-shaped structure plate. The slide rail 101 is laid continuously from left to right along the upper surface of the base 1 and protrudes from the upper surface of the base 1. A T-shaped sliding hole 102 is opened horizontally in the middle of the slide rail 101. Positioning blocks 2 are provided on both sides of the baffle 103 and are slidably connected to the slide rail 101. The bottom of the positioning block 2 has a corresponding recess to the protruding structure of the slide rail 101. The groove 201 has a T-shaped clip 202 protruding from the center of the groove 201, corresponding to the T-shaped sliding hole 102. The positioning block 2 is slidably connected to the slide rail 101 and the T-shaped clip 202 respectively through the groove 201 and the T-shaped clip 202. The upper end of the positioning block 2 is horizontally supported by a tube support 203 with open ends and hollow interior. The upper ends of both positioning blocks 2 can be rotatably fitted with a drive shaft 3. The drive shaft 3 is rotatably nested in the tube support 203. One end of the drive shaft 3 is coaxially connected to a motor 301. The opposite ends of the two drive shafts 3 are provided with clamping blocks 302. The outer circumference of the clamping blocks 302 protrudes. The slide rail 5 has multiple fixed tubes 303 with open tops and hollow interiors. Each fixed tube 303 has a top block 4 embedded inside. First positioning holes are evenly distributed on each fixed tube 303, and multiple second positioning holes are correspondingly formed on each top block 4. Positioning pins are provided between the first and second positioning holes. A first support rod 6 is slidably mounted on the slide rail 5. A second support rod 604 is rotatably connected to the upper end of the first support rod 6. The second support rod 604 extends between two clamping blocks 302. A jump sensor counter 7 is fixedly connected to one end of the second support rod 604 positioned between the clamping blocks 302. A fixing block 601 is provided at the bottom of the support rod 6. The first support surface has threads. A nut 602 is threadedly connected to the first support rod 6. The first support rod 6 is clamped on the slide rail 5 by the fixing block 601 and the nut 602. The first support rod 6 and the second support rod 604 are fixed together by a connector 603. The connector 603 is two block-shaped structures that can be twisted relative to each other and are fixedly connected by a shaft. The second support rod 604 is fixedly connected to the bounce sensor counter 7 by the connector 603. The bounce sensor counter 7 is a structure with a pulley at the lower end and a counter at the upper end.

[0025] During use, this utility model uses the acceleration on the drive shaft 3 at the upper end of the positioning block 2 to clamp the rope wheel to be tested, and drives the drive shaft 3 to rotate after the clamping block 302 has clamped the rope wheel. During the rotation, the jump sensor counter 7 is in contact with the surface of the rope wheel to be tested. When the rope wheel rotates, the jump sensor counter 7, which is in contact with the outer surface of the rope wheel, will jump and provide feedback when it encounters cracks or unevenness on the surface of the rope wheel, thus providing a prompt for maintenance personnel to repair the jumping area, making it more convenient to use.
