[0002] According to the "Coal Mine Safety Regulations", belt conveyors in coal mines (including underground and surface belt corridors) must be equipped with protective devices such as anti-slip (speed), anti-deviation, and anti-coal-piling devices. In order to ensure the sensitivity and reliability of the protective devices, an operation test must be carried out once a day during the maintenance period as required.

[0003] Currently, commonly used anti-slip protection devices for belt conveyors include inductive types. During testing, the mounting bracket of the inductive anti-slip protection device needs to be removed, and then the sensor should be moved away from the drum or its direction changed. The belt conveyor should be able to stop automatically, indicating that the protection is sensitive and reliable. After the test, the mounting bracket of the protection device needs to be re-fixed, which is cumbersome. In addition, before the test, the belt conveyor guardrail needs to be removed while the belt conveyor is running and the drum is rotating, and then the mounting bracket of the inductive speed sensor on the side of the drum needs to be removed, which poses a great safety hazard.

[0040] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0041] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0042] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present utility model, which provides an anti-slip protection mechanism, the mechanism comprising:

[0043] The fixed housing 101 has an internal accommodating space 102. The fixed housing 101 is U-shaped and has a plate-like structure with both ends raised and the bottom horizontal. The middle position of the two raised ends is the accommodating space 102.

[0044] Alternatively, the housing 101 can be a hollow square box, with the hollow portion serving as the accommodating space 102. Preferably, a square box is used, which can block objects from entering the accommodating space 102 from the side.

[0045] The support platform 201 is slidably disposed in the accommodating space 102. The components to be controlled to move can be installed on the support platform 201, and the movement is driven by the support platform 201.

[0046] The drive shaft 301 is movably mounted on the fixed housing 101 with one end located in the accommodating space 102. The drive shaft 301 is connected to the support platform 201 through the control component 302, which drives the support platform 201 to slide in the accommodating space 102.

[0047] The positioning shaft 401 is movably disposed in the fixed housing 101 and inserted into the drive shaft 301; wherein the positioning shaft 401 is slidably inserted into the fixed housing 101.

[0048] Alternatively, the positioning shaft 401 can be connected to the fixed housing 101 by a thread; the end of the positioning shaft 401 is provided with a handle to facilitate the sliding or rotation of the positioning shaft 401.

[0049] The drive shaft 301 is provided with a positioning hole 301a. The positioning shaft 401 cooperates with the positioning hole 301a to restrict the movement of the drive shaft 301. The end of the drive shaft 301 is provided with a control part 301b. The control part 301b is installed at the end of the drive shaft 301 that extends out of the accommodating space 102. The control part 301b can be made into a handle installed at the end of the drive shaft 301 or a turntable.

[0050] When the drive shaft 301 controls the bearing platform 201 to move to the end of the accommodating space 102 and away from the control unit 301b, the end of the positioning shaft 401 coincides with the positioning hole 301a. The positioning shaft 401 can be inserted into the positioning hole 301a to fix the drive shaft 301, thereby fixing the bearing platform 201 to prevent it from moving accidentally.

[0051] The drive shaft 301 is slidably disposed in the fixed housing 101; the control component 302 includes a connecting rod 302a disposed between the bearing platform 201 and the drive shaft 301; the drive shaft 301 is provided with a protrusion and is inserted into the fixed housing 101 to prevent the drive shaft 301 from rotating; or the bearing platform 201 and the drive shaft 301 are directly contacted and fixed, and the contact and fixing part is the control component 302.

[0052] During use, the drive shaft 301 slides on the fixed housing 101, thereby driving the bearing platform 201 to move synchronously in the accommodating space 102. When it moves to the end, the positioning hole 301a coincides with the positioning shaft 401, and the positioning shaft 401 is inserted into the positioning hole 301a to fix the drive shaft 301.

[0053] Example 2, refer to Figure 3 and Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that: Figure 3 As shown, one end of the support platform 201 is slidably inserted into the inner wall of the accommodating space 102; the inner wall of the accommodating space 102 is provided with a groove 102a for one end of the support platform 201 to be inserted into, and the support platform is guided and limited by the groove 102a so that it can only slide along the groove 102a.

[0054] Or such as Figure 4 As shown, a guide shaft 102b is provided in the accommodating space 102. The direction of the guide shaft 102b is consistent with the moving direction of the bearing platform 201. The bearing platform 201 is slidably disposed in the guide shaft 102b. The guide shaft 102b guides and limits the bearing platform, so that it can only slide along the guide shaft 102b.

[0055] The drive shaft 301 is rotatably mounted in the fixed housing 101;

[0056] The control component 302 includes an external thread 302b disposed on the drive shaft 301 and an internal thread 302c disposed inside the support platform 201. The internal thread 302c is disposed in the support platform 201, and the drive shaft 301 passes through the internal thread 302c. The external thread 302b cooperates with the internal thread 302c. When the drive shaft 301 rotates, the cooperation between the external thread 302b and the internal thread 302c can control the movement of the support platform 201.

[0057] The control unit 301b at the end of the drive shaft 301 adopts a polygonal control end provided at the end of the drive shaft 301, including an inner polygonal groove or an outer polygonal side, and controls the rotation of the drive shaft 301 by means of a wrench.

[0058] The remaining structure is the same as that in Example 1.

[0059] Example 3, referring to Figure 5 This is the third embodiment of the present invention, which differs from the second embodiment in that the drive shaft 301 is rotatably disposed in the fixed housing 101;

[0060] The control component 302 includes a spiral groove 302d disposed on the drive shaft 301 and a limiting post 302e disposed at the bottom of the support platform 201;

[0061] The limiting post 302e is slidably inserted into the spiral groove 302d. When the drive shaft 301 rotates, the inner wall of the spiral groove 302d can push the limiting post 302e and the bearing platform 201 to move.

[0062] The remaining structure is the same as that in Example 1.

[0063] Example 4, refer to Figure 6 This is the fourth embodiment of the present invention. This embodiment provides an inductive test device for a conveyor, which includes an anti-slip protection mechanism and a sensor 501, which is installed on a support platform 201.

[0064] During installation, the bottom of the fixed housing 101 is installed at the roller, and the end of the drive shaft 301 is passed through the belt conveyor guard. That is, the control unit 301b is located outside the belt conveyor guard. When the drive shaft 301 is fixed by the positioning shaft 401, the sensor 501 on the bearing platform 201 approaches the roller to monitor the roller.

[0065] When the drive shaft 301 is moved to the end of the carrying platform 201 by controlling the drive shaft 301, the drive shaft 301 is fixed. The fixed housing 101 does not affect the normal operation of the belt conveyor, while ensuring that the protection is sensitive and reliable when the belt conveyor is running normally. The installation position of the anti-slip sensor 501 is accurately determined, avoiding the phenomenon that the distance between the sensor 501 and the magnet is inaccurate due to manual observation or the electrician's lack of responsibility or uneven skill level, which may cause the sensor 501 to be too close to damage the magnet or the protection to malfunction due to being too far away.

[0066] Meanwhile, during daily maintenance, when testing the anti-slip protection, it is only necessary to control the drive shaft 301 to gradually move the sensor 501 away from the drum, and the protection alarm will stop the machine to complete the protection test. After the test, control the drive shaft 301 again to move the bearing platform 201 to the end, and the anti-slip protection sensor 501 will be restored to the installation position. At the same time, the positioning shaft 401 fixes the drive shaft 301 to prevent the belt conveyor from malfunctioning and stopping due to shaking during operation.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
