[0031] Example 1

[0032] Please see Figure 1-4 The present invention provides the following technical solution:

[0033] A coal mine safety-type mechanical fault detection device, comprising:

[0034] Sleeve 1;

[0035] Sliding column 2 is slidably connected inside sleeve 1;

[0036] Top plate 8 is fixedly connected to the upper end of sliding column 2, and rotating rod 9 is rotatably connected to the upper end of top plate 8;

[0037] Ratchet 10 is fixedly connected to the rotating rod 9. Ratchet 11 is rotatably connected to the top plate 8 through a rotating shaft. Ratchet 10 and ratchet 11 are intermittently meshed. Torque spring 12 is connected between ratchet 11 and top plate 8. Torque spring 12 is matched with ratchet 11 and ratchet 10.

[0038] Fault detection mechanism 13 is connected to the upper end of rotating rod 9.

[0039] In a specific embodiment of this utility model, the sleeve 1 serves as the main frame of the entire device, providing a sliding track for the sliding column 2. A latch 3 is provided on one side of the sleeve 1 for engaging with the protrusion 7 to achieve the locking function of the device. The sliding column 2 is slidably connected inside the sleeve 1 and can move up and down as needed to adjust the height of the fault detection device. A mounting groove 4 is provided on the side end of the sliding column 2 for mounting the telescopic rod 5. The top plate 8 is fixedly connected to the upper end of the sliding column 2. A rotating rod 9 is rotatably connected to the upper end of the top plate 8 via a rotating shaft, and the top plate 8 also has a rotating shaft for mounting the ratchet 11. The rotating rod 9 is rotatably connected to the upper end of the top plate 8, and a ratchet 10 is fixedly connected to its upper end. The ratchet 10 is fixedly connected to the upper end of the rotating rod 9 and engages with the ratchet 11 to achieve a unidirectional rotation function. The ratchet 11 is rotatably connected to the top plate 8 via a rotating shaft and intermittently meshes with the ratchet 10 to control the rotation direction of the rotating rod 9. A torque spring 12 is connected between the ratchet 11 and the top plate 8, used to pull the ratchet 11 back to its initial position when it disengages from the ratchet 10. A fault detection mechanism 13 is connected to the upper end of the lever 9 and is used to perform a fault detection function. When the lever 9 rotates, the fault detection mechanism 13 also rotates, thereby changing its angle relative to the ground.

[0040] Please refer to the details. Figure 1-4 The sleeve 1 has a slot 3 on its side end, and the sliding column 2 has a mounting groove 4 on its side end. A telescopic rod 5 is connected in the mounting groove 4. A protrusion 7 is fixedly connected to the side end of the telescopic rod 5. A spring 6 is connected between the telescopic rod 5 and the protrusion 7. The protrusion 7 is movably engaged with the slot 3.

[0041] In this embodiment: A latch 3 is located on the side end of the sleeve 1 and is used to engage with the protrusion 7 to achieve the locking function of the device. The number of latches 3 can be set as needed, usually at least one or more, to lock the slide column 2 in different positions. A mounting groove 4 is located on the side end of the slide column 2 and is used to install the telescopic rod 5. The design of the mounting groove 4 allows the telescopic rod 5 to extend and retract within a certain range, thereby enabling the protrusion 7 to engage or disengage with the latch 3. The telescopic rod 5 is installed in the mounting groove 4 of the slide column 2, and can extend and retract freely within the mounting groove 4. A protrusion 7 is fixedly connected to the side end of the telescopic rod 5. The size and shape of the protrusion 7 are designed to allow it to smoothly enter the latch 3 and engage with it. A spring 6 is connected between the telescopic rod 5 and the protrusion 7 to provide restoring force. When the protrusion 7 is not engaged with the latch 3, the spring 6 is in a compressed state. Once the protrusion 7 is aligned with the latch 3, the spring 6 will push the protrusion 7 into the latch 3, achieving locking. The protrusion 7 is fixedly connected to the side end of the telescopic rod 5. The design of the protrusion 7 allows it to cooperate with the bayonet 3. When the protrusion 7 enters the bayonet 3, it can prevent the slide column 2 from sliding along the sleeve 1, thereby fixing the position of the slide column 2.

[0042] Please refer to the details. Figure 1-4 The lower end of the sleeve 1 is fixedly connected to the base 14.

[0043] In this embodiment, the base 14 is designed to increase the overall stability of the equipment and prevent it from tipping over or moving due to external forces during use. By increasing the contact area between the equipment and the ground, the base 14 improves the stability of the equipment, especially when operating on uneven ground, effectively preventing the equipment from tilting or tipping over.

[0044] Please refer to the details. Figure 1-4 A handle 16 is fixedly connected to the upper end of the base 14.

[0045] In this embodiment: The base 14 is designed to increase the overall stability of the equipment and prevent it from tipping over or moving due to external forces during use. The base 14 is typically made of a heavier material to increase the stability of the equipment's center of gravity and has sufficient width and length to expand the support surface of the equipment. The handle 16 is designed to facilitate the operator's handling and movement of the equipment. It is usually located on one or both sides of the base 14, making it easy for the user to grip and lift the entire equipment.

[0046] Please refer to the details. Figure 1-4 The lower end of the base 14 is fixedly connected to a caster wheel 15.

[0047] In this embodiment, the casters 15 can rotate 360 ​​degrees, allowing the equipment to move in any direction, which greatly improves the equipment's mobility. Operators can easily push the equipment to the location requiring inspection without lifting it. When precise positioning of the equipment is required, the casters 15 allow the equipment to be quickly moved to the designated position without difficulty in adjusting its position due to excessive weight or size.

[0048] Please refer to the details. Figure 1-4 A triangular plate 17 is fixedly connected between the base 14 and the sleeve 1.

[0049] In this embodiment, the triangular plate 17 connects the base 14 and the sleeve 1 to form a stable triangular structure, enhancing the overall rigidity of the equipment and making it less prone to deformation or shaking when subjected to external loads. The connection between the base 14 and the sleeve 1 is also strengthened by the triangular plate 17, further improving the stability of the equipment. Especially when the equipment is subjected to lateral impact, it can better disperse the force, preventing the equipment from tilting or tipping over.

[0050] The working principle and usage process of this utility model are as follows: During use, adjust the height of the sliding column 2 as needed. Pull or push the sliding column 2 to make it slide along the sleeve 1. When the sliding column 2 reaches the desired height, release the sliding column 2. The spring 6 will push the protrusion 7 into the latch 3 on the side of the sleeve 1, thereby locking the position of the sliding column 2. Use the handle 16 to lift the device or push the device to the position to be tested. If the device needs to be moved, unlock the universal wheel 15, push the device to the target position, and then relock the universal wheel 15. Adjust the angle of the fault detection mechanism 13 as needed. By rotating the rotating rod 9, the ratchet 10 and ratchet 11 cooperate to allow the fault detection mechanism 13 to rotate unidirectionally and be fixed at a certain angle. Start the fault detection mechanism 13, execute the fault detection program, read the data displayed by the fault detection mechanism 13, and record it for subsequent analysis. After the test is completed, reset the sliding column 2 to the initial position and close the fault detection mechanism 13. If the device needs to be moved, use the handle 16 again to lift the device or push the device back to the storage position. Store the device in the designated safe location to ensure that the device is in good condition before the next use.
