[0018] 1. By pulling the rope buckle, the extension plate slides outward, so that the rope buckle is away from the lifting plate, and then the rotating plate is flipped outward, so that the reset spring pulls the sliding plate to move horizontally, so that the extension plate overlaps with the locking buckle, and then the rope is squeezed and the extension plate is rotated upward to avoid the position until the rope enters the inside of the rope buckle. The torsion spring resets the extension plate by pulling the rotating shaft, so that the rope that is still in a loose state is restricted to the inside of the rope buckle, which increases the stability of the rope during installation and prevents it from falling off after installation. At this time, the rope buckle is away from the high-temperature mining rack rail, so it can avoid the operation risks caused by unstable center of gravity and proximity to heat sources when workers squat to install the rope.

[0019] 2. By stacking and placing different numbers of pads, the rack rails can be effectively lifted. After the rack rails are stacked and assembled, the height of the lifting plate can be slightly changed by turning the knob with a tool, which in turn causes the lifting plate to push the lifting pads to slightly change the height, ultimately allowing the horizontality of the rack rails to be changed more accurately.

[0030] Several sets of rail assemblies 3 are arranged in parallel on the top surface of the lifting plate 1, and a hanging rope assembly 2 is arranged on the bottom of the lifting plate 1;

[0031] Among them, the hanging rope assembly 2 includes an extension plate 201 symmetrically and slidingly installed on both sides of the bottom of the lifting plate 1, the extension plate 201 is slidably connected to the support leg 101, a cavity 202 is opened inside the center plate 102, the inside of the cavity 202 is symmetrically fixedly connected with a first spring 203, the top of the first spring 203 is fixedly connected with a locking ball 205, and the middle part of the first spring 203 is movably provided with a center column 204, the center column 204 is fixedly connected to the locking ball 205, and the locking ball 205 is engaged with the extension plate 201; after the locking ball 205 is engaged with the extension plate 201, it can prevent the extension plate 201 from sliding out of the lifting plate 1 at will.

[0032] Among them, the end of the extension plate 201 away from the center plate 102 is fixedly connected to the hanging rope buckle 207, and the outer bottom of the hanging rope buckle 207 is slidably connected to the sliding plate 209. The end of the sliding plate 209 located on the inner side of the hanging rope buckle 207 is rotatably installed with an extension plate 211, and the top of the other side of the sliding plate 209 is rotatably installed with a rotating plate 213. The bottom of the sliding plate 209 is fixedly installed with a return spring 215, and the bottom end of the hanging rope buckle 207 is fixedly connected with a locking buckle 208; the inner side of the hanging rope buckle 207 is provided with a groove, and the rope can be clamped in the groove, and the top of the rope is connected to the crane with a hook.

[0033] The top of the sliding plate 209 away from the locking buckle 208 is fixedly connected to a vertical plate 212, and the rotation of the vertical plate 212 is connected to a rotary plate 213, and the rotary plate 213 fits the outer side of the hanging rope buckle 207. The bottom of the sliding plate 209 away from the locking buckle 208 is fixedly connected to a lower convex strip 214, and the lower convex strip 214 is fixedly connected to a return spring 215, and the other end of the return spring 215 is fixedly connected to the hanging rope buckle 207; the return spring 215 can pull the sliding plate 209 to reset.

[0034] The extension plates 201 on both sides are plugged into each other. A ball groove 206 is provided at the bottom of the end of the extension plate 201 away from the lanyard buckle 207. The ball groove 206 is engaged with the locking ball 205. The extension plate 211 is overlapped with the locking buckle 208. The end of the extension plate 211 away from the sliding plate 209 is fixedly connected with a blocking bar 217.

[0035] The end of the extension plate 211 away from the blocking bar 217 is fixedly connected to the rotating shaft 210, and the rotating shaft 210 is rotatably connected to the sliding plate 209. The torsion springs 216 are symmetrically sleeved on both sides of the rotating shaft 210, and the extension plate 211 is also slidably connected to the hanging rope buckle 207; the sliding plate 209 is slidably connected to the hanging rope buckle 207 through the inner groove. The thickness and length of the extension plate 211 are smaller than the sliding plate 209, so it can also enter the inner groove. One end of the torsion spring 216 is fixedly connected to the extension plate 211, and the other end is fixedly connected to the sliding plate 209, and the rotating shaft 210 can only be rotated upward by ninety degrees.

[0036] The rail assembly 3 includes a slide groove 301 opened on the top of the lifting plate 1, and a slide frame 302 is symmetrically slidably connected to the slide groove 301. A number of pads 303 are stacked on the inner bottom surface of the slide frame 302.

[0037] The laminating plate 306 is in contact with the top surface of the pad 303 ; as the number of pads 303 increases, the height of the laminating plate 306 will also change.

[0038] Working principle: Before using this kind of quenching positioning device for mining racks, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 7 The cam 207 is then released from the engagement of the locking ball 205 with the ball groove 206, thereby allowing the extension plate 201 to slide outward smoothly, thereby allowing the cam 207 to move away from the lifting plate 1. At this time, the rotary plate 213 is turned outward, so that the return spring 215 pulls the sliding plate 209 to move horizontally, thereby allowing the extension plate 211 to overlap the locking buckle 208, and the rope is pushed upward, so that the rope is squeezed and the extension plate 211 rotates upward to avoid the position until the rope enters the inner side of the cam 207. The torsion spring 216 pulls the rotating shaft 210 to return the extension plate 211 to its original position, so that the rope, which is still in a loose state, is restricted to the inner side of the cam 207, thereby increasing the stability of the rope during installation and preventing it from falling off after installation. In addition, when installing, the worker is in a squatting position, and the cam 207 is away from the high-temperature mining rack rail. Therefore, it is safer for the worker to install the rope when squatting.

[0039] After the rope is installed, push the extension plate 201 back to its original position so that the two extension plates 201 on both sides are plugged into the center plate 102. At this time, the device together with the rack above it can be placed into the quenching tank using an external crane.

[0040] By stacking and placing different numbers of pads 303, the racks can be effectively lifted. After the racks are stacked and assembled, the height of the lifting plate 304 is slightly changed by turning the knob 307 with a tool, and the height of the lifting plate 304 pushes the lifting pad 308 to change slightly, ultimately making the horizontality of the rack more accurately changed.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
