Description

Technical Field

[0001] This utility model relates to the field of pin detection technology for mining hoisting containers, specifically to a continuous detection device for pins of mining hoisting containers. Background Technology

[0002] Mine hoisting and transportation is a crucial link in the mining production process. Ore or gangue mined from various working faces is transported underground to the bottom yard by transport equipment, and then hoisted to the surface. The lifting and lowering of underground workers, as well as the transport of materials and equipment, all rely on hoisting and transportation equipment. The saying "Transportation is the artery of the mine, hoisting is its throat" aptly describes the working process and vital role of the mine hoisting and transportation system. A hoisting system mainly consists of a hoisting container, hoisting wire rope, hoisting machine, sheave, headframe (or tower), and loading and unloading equipment. The connecting pin of the mine hoisting container is a critical component ensuring safe mine production. According to MTT 684—1997 "Non-destructive Testing Methods and Acceptance Specifications for Important Load-bearing Components of Mine Hoisting Containers," the pin must undergo non-destructive testing before use and can only be used after passing the test. Existing magnetic particle flaw detectors mostly require manual loading when performing non-destructive testing on pins. The pins to be inspected are manually stacked onto the feeding mechanism of the magnetic particle flaw detector from the tray, which is labor-intensive and affects the testing efficiency. In view of this, this case was developed after in-depth research on the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a continuous detection device for the pin shaft of a mining hoisting container, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a continuous inspection device for pin shafts of mining hoisting containers, comprising a horizontal truss disposed on one side of the feeding mechanism of the magnetic particle flaw detector body, a movable adjustment mechanism disposed on the horizontal truss, a movable seat disposed at the moving end of the movable adjustment mechanism, a vertical adjustment mechanism disposed at the lower part of the movable seat, a mounting seat disposed at the lower end of the vertical adjustment mechanism, a plurality of pneumatic grippers disposed on the mounting seat, a fixed-distance supply mechanism disposed below the horizontal truss, a placement platform disposed at the moving end of the fixed-distance supply mechanism, a tray disposed on the placement platform, brackets evenly disposed on the tray, and pin shafts to be inspected being placed sequentially on the brackets.

[0005] The aforementioned movable adjustment mechanism includes a U-shaped groove, a transmission screw, and guide rods. The U-shaped groove is disposed on the lower end face of the horizontal beam of the horizontal truss. The transmission screw is rotatably disposed within the U-shaped groove. The exposed end of the transmission screw is connected to a servo drive assembly. The guide rods are symmetrically disposed on both sides of the transmission screw. The movable seat is threadedly engaged with the transmission screw via a screw nut and is slidably connected to the guide rods on both sides.

[0006] The aforementioned vertical adjustment mechanism includes an electric push rod, a limiting sleeve, and a limiting post. The electric push rod is vertically mounted on the lower end of the movable seat, and its telescopic end is fixedly connected to the mounting seat. The limiting sleeve is symmetrically arranged on both sides of the electric push rod. The upper part of the limiting post slides in conjunction with the limiting sleeve, and its lower end is fixedly connected to the mounting seat.

[0007] The aforementioned fixed-distance supply mechanism includes a fixed frame, a lead screw module, a guide rail, and a slider. The fixed frame is located below the horizontal truss. The lead screw module is mounted on the fixed frame and its moving end is connected to the placement platform. The guide rail is symmetrically arranged on both sides of the lead screw module. The slider is slidably mounted on the guide rail and connected to the placement platform.

[0008] The aforementioned placement platform has positioning grooves at its four corners, and positioning blocks are provided at the four corners of the lower end of the tray, with the positioning blocks matching the positioning grooves.

[0009] The tray has handles on both sides.

[0010] This utility model provides a continuous testing device for pins in mining hoisting containers. It has the following advantages: This continuous testing device for pins in mining hoisting containers improves upon the existing magnetic particle flaw detector body by installing a horizontal truss on one side of the magnetic particle flaw detector's feeding mechanism. During testing, a tray containing the pins to be tested is placed on the placement platform. The moving adjustment mechanism is activated to adjust the horizontal position of the pneumatic grippers, aligning them above the tray. The vertical adjustment mechanism is then activated, causing the pneumatic grippers to descend to both sides of the pins and clamp them. After clamping, the vertical adjustment mechanism is reset, and further... The pin is moved above the feeding mechanism via the adjustment mechanism, the pneumatic gripper descends, and the pneumatic gripper is released to place the pin on the feeding mechanism. This, in conjunction with the magnetic particle inspection machine, enables magnetic particle inspection of the pin. During this process, the fixed-distance feeding mechanism pushes the placement table to move a set distance to one side of the feeding mechanism, facilitating the next pin gripping. The above steps are repeated until the pin on the tray is completely fed into the feeding mechanism. Then, the placement table is reset, and the tray can be replaced. The system is compact, highly automated, and can effectively reduce the labor intensity of inspection personnel, greatly improving the efficiency of inspection operations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Refer to the appendix of the instruction manual Figure 1-4As can be seen, this application specifically designs a continuous testing device for pins of mining lifting containers, including a horizontal truss 2 set on one side of the feeding mechanism 1 of the magnetic particle flaw detector body, a movable adjustment mechanism set on the horizontal truss 2, a movable seat 3 set on the moving end of the movable adjustment mechanism, a vertical adjustment mechanism installed at the lower part of the movable seat 3, a mounting seat 4 set at the lower end of the vertical adjustment mechanism, a plurality of pneumatic grippers 5 set on the mounting seat 4, a fixed-distance supply mechanism set below the horizontal truss 2, a placement platform 6 set on the moving end of the fixed-distance supply mechanism, a tray 7 placed on the placement platform 6, and brackets 8 evenly arranged on the tray 7. The pins to be tested are placed on the brackets 8 in sequence.

During testing, the tray 7 containing the pins to be tested is placed on the placement platform 6, the movable adjustment mechanism is started, and the movable adjustment mechanism is used to... Adjust the horizontal position of the pneumatic gripper 5 so that it is aligned above the tray 7. Control the vertical adjustment mechanism to move the pneumatic gripper 5 downwards to both sides of the pin. Control the pneumatic gripper 5 to clamp the pin. After clamping, control the vertical adjustment mechanism to reset and further move the pin above the feeding mechanism 1 via the moving adjustment mechanism. The pneumatic gripper 5 moves downwards and is then released, placing the pin on the feeding mechanism. This, in conjunction with the magnetic particle inspection machine body, enables magnetic particle inspection of the pin. During this process, the fixed-distance feeding mechanism pushes the placement table 6 to move a set distance to one side of the feeding mechanism, facilitating the next pin gripping. Repeat the above steps until the pin on the tray 7 is completely fed into the feeding mechanism. Then, control the placement table 6 to reset and replace the tray 7. This system is compact, highly automated, effectively reduces the labor intensity of inspection personnel, and greatly improves the efficiency of inspection operations.

[0018] In specific implementation, as a preferred configuration, the aforementioned movable adjustment mechanism includes a U-shaped groove 9, a transmission screw 10, and guide rods 11. The U-shaped groove 9 is located on the lower end face of the crossbeam of the horizontal truss 2. The transmission screw 10 is rotatably mounted within the U-shaped groove 9, and its exposed end is connected to the servo drive assembly. The guide rods 11 are symmetrically arranged on both sides of the transmission screw 10. The movable seat 3 is threadedly engaged with the transmission screw 10 via a screw nut, and its two sides are slidably connected to the guide rods 11 respectively. In use, the servo drive assembly can be used to control the rotation of the transmission screw 10, thereby driving the movable seat 3. The movable seat 3 can reciprocate in the horizontal direction under the limiting engagement of the guide rods 11 on both sides, thereby driving the lower vertical adjustment mechanism and the pneumatic gripper 5 at the bottom of the mounting plate to move synchronously. The structure is simple and highly reliable. The servo drive assembly is a rotary output device powered by a servo motor.

[0019] In specific implementation, as a preferred configuration, the above-mentioned vertical adjustment mechanism includes an electric push rod 12, a limiting sleeve 13, and a limiting post 14. The electric push rod 12 is arranged vertically on the lower end of the movable seat 3 and its telescopic end is fixedly connected to the mounting seat 4. The limiting sleeve 13 is symmetrically arranged on both sides of the electric push rod 12. The upper part of the limiting post 14 is slidably engaged with the limiting sleeve 13, and the lower end is fixedly connected to the mounting seat 4. In use, the expansion and contraction of the telescopic end of the electric push rod 12 can be used to push the mounting plate to move and adjust in the vertical direction. The limiting posts 14 and the limiting sleeve 13 arranged on both sides can further improve the stability of the mounting plate during the adjustment process.

[0020] In specific implementation, as a preferred configuration, the above-mentioned fixed-distance supply mechanism includes a fixed frame 15, a lead screw module 16, a guide rail 17, and a slider 18. The fixed frame 15 is located below the horizontal truss 2. The lead screw module 16 is mounted on the fixed frame 15 and its moving end is connected to the placement platform 6. The guide rail 17 is symmetrically arranged on both sides of the lead screw module 16. The slider 18 is slidably mounted on the guide rail 17 and connected to the placement platform 6. The lead screw module 16 serves as the power source to adjust the position of the placement platform 6 in the horizontal direction, thereby cooperating with the upper pneumatic gripper 5 to achieve continuous supply of the pin shaft.

[0021] In the specific implementation process, as a preferred setting, positioning grooves 19 are respectively opened at the four corners of the placement platform 6, and positioning blocks 20 are respectively set at the four corners of the lower end of the tray 7. The positioning blocks 20 match the positioning grooves 19, which can effectively improve the accuracy of the placement of the tray 7 and further improve the efficiency of the inspection operation. Handles 21 are provided on both sides of the tray 7 to facilitate the picking up and putting down of the tray 7.

[0022] It is important to note that the selection and structural features of the aforementioned magnetic particle flaw detector body can be referenced from the pin-shaft magnetic particle flaw detector produced by Jiangsu Zhongkai Flaw Detection Equipment Manufacturing Co., Ltd.
