[0021] In order to more clearly understand the above - mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1 - 5As shown in the figure, the utility model provides a special frame sling for a warehouse, including: a sling frame 1; a fixing component 2, which is provided in multiple groups. The multiple groups of fixing components 2 are symmetrically and fixedly connected to the inner surface of the sling frame 1. The fixing component 2 includes a fixing block 201, the fixing block 201 is fixedly connected to the inner surface of the sling frame 1, a top plate 202 is fixedly connected to the top of the fixing block 201, a movable plate 206 is arranged at the inner bottom of the fixing block 201, a connecting rod 203 is fixedly connected to the top of the movable plate 206, and the connecting rod 203 slidably penetrates through the top plate 202; a limiting component 3, which is provided in multiple groups. The multiple groups of limiting components 3 are symmetrically arranged at the top of the sling frame 1. The limiting component 3 includes a mounting plate 301 and a dovetail slider 303. The mounting plate 301 is fixedly connected to the top of the connecting rod 203, and a plurality of limiting rods 302 are symmetrically and fixedly connected to the bottom of the mounting plate 301. The outer surfaces of the plurality of limiting rods 302 sequentially slidably penetrate through the top of the sling frame 1 and the dovetail slider 303 and extend into the interior of the sling frame 1; a hook component 4, which is provided in multiple groups. The multiple groups of hook components 4 are fixedly connected to the bottoms of the plurality of dovetail sliders 303. The hook component 4 includes a mounting block 401. A plurality of dovetail chutes 7 are respectively equidistantly opened on the outer surfaces of both sides of the sling frame 1. The dovetail chutes 7 are arranged in a matching manner with the dovetail sliders 303. Springs 205 are symmetrically and fixedly connected between the movable plate 206 and the top plate 202. The springs 205 are located outside the fixed rods 204. A mounting rod 402 is fixedly connected to the bottom of the mounting block 401, and a self-unhooking hook 403 is fixedly connected to the bottom of the mounting rod 402. Fixing plates 5 are fixedly connected to the top of the sling frame 1 near the four corner positions, and lifting lugs 6 are fixedly connected to the tops of the plurality of fixing plates 5.

[0024] The effect achieved by the entire Embodiment 1 is that when the special warehouse frame sling is in use, fixing plates 5 are fixedly connected to the top of the sling frame 1 near the four corners, and lifting lugs 6 are fixedly connected to the top thereof. The lifting lugs 6 distributed at the four corner positions facilitate keeping the whole stable when connected to the steel cable. Pull the pull rod at the top of the mounting plate 301 to drive the connecting rod 203 to move upward, so that the movable plate 206 will slide along the outer surfaces of the two fixed rods 204 and squeeze the two springs 205, causing them to deform and contract between the movable plate 206 and the top plate 202. Furthermore, the mounting plate 301 drives the plurality of limiting rods 302 to slide out of the dovetail slider 303. Personnel cooperate to hold the mounting rod 402 and translate it outward. Since the mounting block 401 is fixedly connected to the dovetail slider 303, the dovetail slider 303 will move out of the dovetail chute 7, facilitating personnel to take out the damaged self-unhooking hook 403 and replace it. Reverse the above steps. Under the elastic reset action of the spring 205, the spring 205 pushes the movable plate 206 to reset and abut against the inner bottom of the fixed block 201. At the same time, the plurality of limiting rods 302 fixedly arranged at the bottom of the mounting plate 301 will synchronously penetrate the outer surface of the dovetail slider 303 and extend into the sling frame 1, playing a role of rapid disassembly and replacement, and solving the problem in the background technology that the hook and the frame sling are fixedly connected by welding or a large number of bolts. Once a certain hook is severely worn and needs to be replaced, it is rather laborious for personnel during the replacement process and not convenient to use.

[0025] Embodiment 2: As Figures 1 - 5 shown, fixed rods 204 are symmetrically and fixedly connected to the inner bottom of the fixed block 201. The tops of the two fixed rods 204 are fixedly connected to the bottom of the top plate 202. Sleeve bushes 207 are symmetrically and fixedly connected to the inner surface of the movable plate 206, and the inner surface of the sleeve bushes 207 is fixedly connected to the outer surface of the fixed rods 204.

[0026] The effect achieved by the entire Embodiment 2 is that when in use, fixed rods 204 are symmetrically and fixedly connected to the inner bottom of the fixed block 201. When the movable plate 206 moves up and down, the sleeve bushes 207 symmetrically and fixedly connected to its inner surface slide on the surfaces of the two fixed rods 204 synchronously, playing a role of limiting, preventing the position from shifting when personnel pull the mounting plate 301 and affecting the docking of the plurality of limiting rods 302 and the dovetail slider 303, and having high practicability.

[0027] Working principle: When the special frame sling for the warehouse is in use, fixing plates 5 are fixedly connected to the top of the sling frame 1 near the four corners, and lifting lugs 6 are fixedly connected to the top thereof. The lifting lugs 6 distributed at the four corner positions facilitate keeping the whole stable when connecting with the steel cable. Pull the pull rod at the top of the mounting plate 301 to drive the connecting rod 203 to move upward, so that the movable plate 206 will slide along the outer surfaces of the two fixed rods 204 and squeeze the two springs 205, causing them to deform and contract between the movable plate 206 and the top plate 202. Then, the mounting plate 301 drives a plurality of limiting rods 302 to slide out from the inside of the dovetail slider 303. Personnel cooperate to hold the mounting rod 402 and translate it outward. Since the mounting block 401 is fixedly connected to the dovetail slider 303, the dovetail slider 303 will move out in the dovetail chute 7, facilitating personnel to take out the damaged self-unhooking hook 403 and replace it. Reverse the above steps. Under the elastic reset action of the spring 205, the spring 205 pushes the movable plate 206 to reset and abut against the inner bottom of the fixed block 201. At the same time, a plurality of limiting rods 302 fixedly arranged at the bottom of the mounting plate 301 will synchronously penetrate the outer surface of the dovetail slider 303 and extend into the sling frame 1, playing a role in quick disassembly and replacement. Fixed rods 204 are symmetrically and fixedly connected to the inner bottom of the fixed block 201. When the movable plate 206 moves up and down, the sliding sleeves 207 symmetrically and fixedly connected to the inner surface thereof slide on the surfaces of the two fixed rods 204 synchronously, playing a role in limiting, preventing the position from shifting when personnel pull the mounting plate 301 and affecting the docking of the plurality of limiting rods 302 with the dovetail slider 303, and having high practicability.

[0028] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
