Technical Field

[0001] This utility model relates to the field of silicon steel coil hoisting technology, specifically a silicon steel coil hoisting device. Background Technology

[0002] The C-hook (also called C-lifting tool) used for hoisting silicon steel coils is a tool specifically designed for the safe and efficient handling of coiled materials such as silicon steel coils. Its unique C-shaped structure allows it to be directly inserted into the inner hole of the steel coil for hoisting.

[0003] Most of the C-type lifting devices commonly found on the market do not have an anti-detachment structure. During the lifting of silicon steel coils, if the coils shake unexpectedly, they are very likely to fall off the C-type lifting devices, causing major production accidents. Based on this, a silicon steel coil lifting device is provided. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-5 In this embodiment of the utility model, a silicon steel coil hoisting device includes a hoisting assembly 1 consisting of a C-shaped hook 101 and a hoisting lug 102. Two hoisting lugs 102 are provided, and the two hoisting lugs 102 are symmetrically fixed to the top of the horizontal part above the C-shaped hook 101. Connecting side plates 103 are symmetrically fixed on both sides of the vertical part of the C-shaped hook 101, and two symmetrically distributed inclined sliding grooves 104 are provided on the two connecting side plates 103. The connecting side plate 103 is equipped with an auxiliary clamping assembly 2 via an inclined slide 104. The auxiliary clamping assembly 2 is used to clamp the outside of the hoisted steel coil 3. The auxiliary pressing assembly 2 includes a convex slide 201, a connecting seat 202, and a pressure roller 203; The convex slide block 201 is distributed at the rear end of the connecting side plate 103 and is slidably connected to the inclined slide groove 104. The convex slide block 201 passes through the inclined slide groove 104 to the front end of the connecting side plate 103 and is fixedly connected to the connecting seat 202. The pressure roller 203 is rotatably connected to the inner side of the connecting seat 202 through a pin. Two pressure rollers 203 are symmetrically distributed around the C-shaped hook 101. The two pressure rollers 203 move down along the inclined tracks of the two inclined slides 104 to press the steel coil 3 that is sleeved on the outer side of the horizontal part below the C-shaped hook 101. The auxiliary clamping assembly 2 also includes a guide post 206, a hydraulic cylinder 207, a pusher 208, and a linear slide 209; The guide post 206 is fixed to the rear end of the convex slide block 201 near the bottom; Hydraulic cylinder 207 is fixedly installed at the bottom of the vertical part of C-type hook 101, push seat 208 is installed at the top of the output end of hydraulic cylinder 207, linear slide groove 209 is symmetrically opened on both sides of the rear end of hydraulic cylinder 207 and completely penetrates hydraulic cylinder 207, and two guide posts 206 extend into the two linear slide grooves 209 respectively and are slidably connected to the linear slide grooves 209. The pusher 208 is driven to move up and down by the hydraulic cylinder 207, which provides power for the tilting and up and down movement of the convex slide 201, the connecting seat 202, and the pressure roller 203; A guide rail 210 is fixed to the rear end of the connecting side plate 103, and a slide block 211 is slidably installed on the outer side of the guide rail 210. The push block 208 is connected and fixed to the slide block 211.

[0015] In this embodiment, it should be noted that the lifting lug 102 is used to connect to the hook of external lifting equipment, and its operating principle is as follows: The lifting equipment is used to transfer the lifting assembly 1, and the bottom horizontal part of the C-type hook 101 is inserted into the inside of the steel coil 2. Then it is slowly lifted so that the bottom horizontal part of the C-type hook 101 is in contact with the inner surface of the steel coil 2. At the same time, the hydraulic cylinder 207 is activated to retract, and the hydraulic cylinder 207 drives the pusher 208 to move down. The pusher 208 drives the guide post 206, the convex slide 201, the connecting seat 202, and the pressure roller 203 to move down through the linear slide groove 209. During this process, the guide post 206, the convex slide 201, the connecting seat 202, and the pressure roller 203 move down at an angle along the trajectory of the inclined slide groove 103, and the guide post 206 slides horizontally inside the linear slide groove 209. The above operation allows the two pressure rollers 203 to tilt downwards and move closer to the outside of the steel coil 3, thereby achieving a pressing operation on the outside of the reinforcing bar 3 (e.g., Figure 1 , Figure 2 Thus, when encountering swaying during subsequent lifting and transfer, the reinforcing bar 3 can maintain a tight fit with the bottom horizontal part of the C-shaped hook 101, effectively preventing the hook from coming off.

[0016] Please refer to this carefully. Figures 1-5 The top rear end and bottom front end of the connecting seat 202 are provided with notches and grooves 204. The notches and grooves 204 are connected to the cavity inside the connecting seat 202 for the pressure roller 203 to rotate. The notches and grooves 204 are used to provide the pressure roller 203 with a small downward rotation space. A limit switch 205 is mounted on the rear end of the convex slide 201 via a bracket. The limit switch 205 passes through the convex slide 201 to the inner side of the cavity inside the connecting seat 202 for the pressure roller 203 to rotate. A through hole is opened inside the convex slide 201 for the limit switch 205 to pass through. When the pressure roller 203 rotates to a horizontal state, the rear end of the pressure roller 203 contacts and squeezes the contact of the limit switch 205. A control box 212 is installed on the top of the vertical part of the C-type hook 101. The control box 212 contains a hydraulic control system that controls the operation of the hydraulic cylinder 207 and a battery. The limit switch 205 is electrically connected to the controller of the hydraulic control system through a wire.

[0017] In this embodiment, it should be noted that the battery is used to provide power for the operation of the hydraulic control system. The battery can be charged via a power cord or directly replaced (the battery replacement structure can adopt the conventional replacement structure in the existing technology), thus meeting the needs of hoisting operations. When not being hoisted, the pressure roller 203 tilts slightly downwards under its own weight (e.g., Figure 3 At this time, the rear end of the pressure roller 203 is not in contact with the limit switch 205 (e.g. Figure 5 When pressing the steel coil 3, the hydraulic cylinder 207 is activated by an external remote control to retract and move the pressure roller 203 downward. As the pressure roller 203 moves downward and contacts the steel coil 3, it rotates to a horizontal position (it should be noted that the connecting seat 202 limits the rotation angle of the pressure roller 203 so that the pressure roller 203 is ultimately kept in a horizontal position). At this time, the pressure roller 203 presses the steel coil 3. At the same time, the rear end of the pressure roller 203 contacts the contact of the limit switch 205 and squeezes it. The limit switch 205 sends a signal to the controller, and the controller stops the hydraulic rod 207 from continuing to operate, thereby avoiding excessive squeezing of the steel coil 3.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
