Description

Technical Field

[0001] The utility model relates to the technical field of fall arrester performance detection equipment, in particular to a mine fall arrester performance detection device. Background Art

[0002] A mine fall arrester is a safety device designed specifically for high-altitude and underground operations in mines. It can be quickly locked in an emergency by automatic or manual means to prevent people from falling or intercept falling objects, thereby ensuring the safety of miners and the integrity of equipment. It is a key equipment for safe production in mines, and the performance testing of the fall arrester is an important measure to ensure the safety of mine operations. It can promptly discover and resolve potential safety hazards of the fall arrester, ensure that it can function quickly and effectively in an emergency, and prevent falling accidents.

[0003] However, most of the existing methods for testing the performance of a fall arrester involve mounting a hook at one end of the fall arrester on a fixed ring on the base, and mounting the other end of the hook on a lifting ring on the top plate, and tightening the fall arrester to test its performance. However, since the lifting ring is fixed to the lower end surface of the top plate and cannot be moved, when the fall arrester is hoisted on the top plate for tightening, the fall arrester shakes and easily pulls the lifting ring from different directions, causing the lifting ring to be subjected to tension in different directions, thereby causing the lifting ring to wear and reducing its service life. Therefore, those skilled in the art provide a performance testing device for a mine fall arrester to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a performance detection device for a mine fall arrester to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The cam is fixed on the upper end of the crossbar, and the cam is fixed on the lower ...

[0007] Preferably, a sliding groove is provided inside the crossbar, the slide plate is slidably installed inside the sliding groove, and the depth of the sliding groove is greater than the thickness of the slide plate.

[0008] Preferably, an opening communicating with the slide groove is formed on the upper end surface of the cross bar, and the threaded column passes through the opening, extends to the top of the cross bar, and slides inside the cross bar.

[0009] Preferably, the diameter of the slide is larger than the inner diameter of the opening.

[0010] Preferably, a through hole is opened at a position on the end surface of the end plate corresponding to the threaded column, and the threaded column passes through the through hole and extends to the top of the end plate.

[0011] Preferably, a U-shaped card slot is provided inside the U-shaped card plate, and the U-shaped card plate is mounted on the bottom of the cross bar through the U-shaped card slot and inserted into the inside of the through slot.

[0012] Preferably, support ears are provided on both sides of the U-shaped pallet, and a fixing bolt is provided at the top of the end plate corresponding to the support ear. The fixing bolt passes through the end plate and the support ear and extends to the bottom thereof, and a fixing nut is provided at one end of the fixing bolt located below the U-shaped pallet. The fixing nut thread is installed on the outer wall of the fixing bolt and is tightly attached to the lower end face of the U-shaped pallet.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] By setting up chains and rings, when the fall arrester is tightened, the ring can drive the chain to shake as the fall arrester shakes, thereby buffering the tension on the ring. This avoids the situation where the fall arrester shakes and applies tension to the ring from different directions due to the fixed position of the ring, reduces the wear of the ring, and extends the service life of the ring.

[0015] By setting a limit seat, when hoisting the fall arrester, the position of the limit seat in the through groove can be adjusted, and the limit seat can be moved by pulling the lifting ring through the chain, and the height between the lifting ring and the base can be adjusted. This can increase the tensioning stroke of the fall arrester, change the tensioning force on the fall arrester, and expand the performance test range of the fall arrester. It is suitable for testing different models of fall arresters and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Combine Figures 1-4 As shown, the detection seat 1 is provided with an adjustment plate 2 for transmission, and four through slots 201 are evenly opened on the adjustment plate 2, and a cross bar 21 is provided inside the through slot 201, and a limit seat 3 is slidably installed on the outside of the cross bar 21, and the limit seat 3 includes an end plate 31 and a U-shaped card plate 32, wherein the end plate 31 is provided above the adjustment plate 2 and covers the cross bar 21, the U-shaped card plate 32 is provided below the adjustment plate 2 and is clamped and installed at the bottom of the cross bar 21, and a slide plate 22 is slidably installed inside the cross bar 21, and the slide plate 2 2 is provided with a threaded column 23 on the end face, and the threaded column 23 passes through the cross bar 21 and the end plate 31 and extends above it. A limit nut 231 is provided at one end of the threaded column 23 located above the end plate 31. The limit nut 231 is threadedly installed on the outer wall of the threaded column 23 and is tightly attached to the upper end face of the end plate 31. In addition, a lifting ring 5 for installing a fall arrester is provided just below the adjusting plate 2. A chain 4 is provided at one end of the four U-shaped clamping plates 32 away from the cross bar 21, and the other ends of the four chains 4 are installed on the top of the lifting ring 5.

[0023] In one embodiment, when installing the limit seat 3, the end plate 31 can be first covered on the top of the through groove 201, and the threaded column 23 on the top of the cross bar 21 can be inserted into the through hole 311 inside the end plate 31, and then the U-shaped clamping plate 32 can be inserted into the through groove 201, and the U-shaped clamping plate 32 can be clamped to the bottom of the cross bar 21 through the U-shaped clamping groove 321, and the ears 322 at both ends of the U-shaped clamping plate 32 can be fitted on the lower end surface of the end plate 31, and then the fixing bolts 33 can be tightened. The bolt 33 is installed inside the end plate 31 and the support ear 322, and the fixing nut 331 is installed on the fixing bolt 33, so that the fixing nut 331 is tightly against the lower end surface of the support ear 322 and the fixing bolt 33 is tightened to complete the installation of the limit seat 3. The limit seat 3 can be installed inside the adjustment plate 2, and the four limit seats 3 can be used to pull the chain 4 from the four corners of the adjustment plate 2, and the lifting ring 5 is lifted to the bottom of the adjustment plate 2 to lift the anti-fall device, which facilitates the performance testing of the anti-fall device.

[0024] In one embodiment, when adjusting the position of the limit seat 3, the limit seat 3 can be slid in the through groove 201, so that the limit seat 3 is displaced outside the cross bar 21, and then the end plate 31 drives the threaded column 23 inserted inside it to displace in the opening 212, thereby driving the slide plate 22 installed at the bottom of the threaded column 23 to displace in the slide groove 211, and the threaded column 23 will not interfere with the movement of the end plate 31 and the slide plate 22, thereby ensuring the position adjustment of the limit seat 3.

[0025] In one embodiment, when adjusting the height of the hanging ring 5, the limit seat 3 can be slid in the through groove 201 to adjust the positions of the four limit seats 3, so that the four limit seats 3 drive the chains 4 installed at the bottom thereof to move, and the four chains 4 pull the hanging ring 5 in all directions, and adjust the height between the hanging ring 5 and the base. This can increase the tensioning stroke of the fall arrester, change the tensioning force on the fall arrester, and expand the performance test range of the fall arrester. It is suitable for testing different models of fall arresters and is highly practical.

[0026] In one embodiment, when limiting the limit seat 3, the threaded column 23 can be pulled upward, allowing the threaded column 23 to pull the slide plate 22 to move upward inside the slide groove 211 and tightly adhere to its inner wall to cover the opening 212, and then the limit nut 231 is screwed to allow the limit nut 231 to tightly adhere to the upper end surface of the end plate 31 to limit the position of the slide plate 22. The end plate 31 can be clamped between the slide plate 22 and the limit nut 231 for limiting the position, thereby completing the limitation of the limit seat 3 after the adjustment position, and can limit the position of the limit seat 3 to prevent the limit seat 3 from being displaced, thereby avoiding the situation where the limit seat 3 is displaced and the lifting ring 5 is pulled by the chain 4 to move, causing the anti-fall device hung thereon to be skewed, thereby ensuring the progress of the anti-fall device performance test.

[0027] In one embodiment, when the fall arrester is hoisted on the ring 5, the ring 5 can be allowed to swing along with the swing of the fall arrester to drive the chain 4 to swing, thereby reducing the friction between the hook on the fall arrester and the ring 5, and preventing the ring 5 from being subjected to tension in all directions. This avoids the situation where the fall arrester swings due to the fixed position of the ring 5, causing the hook to apply tension and friction to the ring 5 from different directions, thereby extending the service life of the ring 5.

[0028] The working principle of the present invention is as follows: when testing different types of fall arresters, the limit seat 3 can be slid in the through groove 201 to allow the limit seat 3 to displace on the outside of the cross bar 21, and the end plate 31 can drive the threaded column 23 inserted in it to displace in the opening 212, and then pull the threaded column 23 upward to allow the threaded column 23 to pull the slide plate 22 to displace upward in the slide groove 211 and tightly adhere to its inner wall to cover the opening 212, and then screw the limit nut 231 to allow the limit nut 231 to tightly adhere to the upper end surface of the end plate 31 to limit the position of the slide plate 22, and the end plate 31 can be clamped between the slide plate 22 and the limit nut 231 to limit the position, thereby completing the position adjustment of the limit seat 3, and the position of the four limit seats 3 can be adjusted, so that the four limit seats 3 drive the chain 4 installed at the bottom thereof to displace, and the four chains 4 are pulled to the surroundings. The lifting link 5 is moved to adjust the height between the lifting link 5 and the base, thereby increasing the tightening stroke of the fall arrester, changing the tightening force on the fall arrester, and expanding the performance test range of the fall arrester. It is suitable for testing fall arresters of different models and has strong practicality. Moreover, when performing a performance test on the fall arrester, the hooks at both ends of the fall arrester are respectively installed on the lifting link 5 and the clamping ring on the base, and then the driving mechanism drives the adjusting plate 2 to move on the detection seat 1, so that the fall arrester can be tightened to perform a performance test on it, and the lifting link 5 can be made to drive the chain 4 to shake with the shaking of the fall arrester, thereby reducing the friction between the hook and the lifting link 5 on the fall arrester, and preventing the lifting link 5 from being subjected to tension in all directions, thereby avoiding the situation where the fall arrester shakes due to the fixed position of the lifting link 5, causing the hook to apply tension and friction to the lifting link 5 from different directions, thereby extending the service life of the lifting link 5.
