Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of hook storage devices, and particularly relates to a steel plate hoisting device. Background Technology
[0002] In fields such as steel structure production, the movement of steel plates requires the use of overhead cranes. Currently, steel plate hoisting devices mainly include the following two types: First, two opposing hoisting ropes, hooks, and lifting rings. The lifting rings are hung on the crane hooks, and the hooks are hooked on both sides of the steel plate. The hooks rely on the lateral tension of the inclined hoisting ropes to generate an inward horizontal tension, preventing the hooks from slipping off the steel plate. This type of hoisting device is convenient to attach and detach, but there is still a risk that the hooks may slip off the steel plate. Second, a hoisting rope with a lifting ring at the top and a hook with a hook frame, wherein the hoisting rope is a single rope. When hoisting steel plates, the hooks are attached to both sides of the steel plate, the overhead crane hooks are attached to the lifting rings, and the lifting ropes are triangular. When hoisting steel plates, the lateral force of the hooks is large, which effectively avoids the risk of the hooks slipping off the steel plates. However, this device has the following defects: after the steel plates are unloaded, the two hooks slide together along the lifting ropes under their own weight. When it is necessary to hoist the steel plates again, two workers need to go to the middle of the steel plates to be hoisted, each grab one hook, and pull the hooks towards the edge of the steel plates. This results in high labor intensity and low labor efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a steel plate hoisting device that has low labor intensity, small space occupation, high safety performance and is easy to detach and hang.
[0004] To solve the above problems, the technical solution adopted by the steel plate hoisting device of this utility model is as follows: it includes a hoisting rope with a hoisting ring at the top and a hook with a hook frame. There is one hoisting rope and two hook frames and hooks. The hook frame includes a first rotating wheel, a second rotating wheel and a side guard plate. The hoisting rope passes around the first rotating wheel and the hook is fixed to the second rotating wheel. A support sleeve is fitted on the outside of the hoisting rope between the two hook frames.
[0005] Its additional technical features are:
[0006] Tensioning springs are provided at both ends of the support sleeve;
[0007] A top cup is provided on the side of the tensioning spring near the hook frame;
[0008] The support sleeve comprises two mating half-sleeves.
[0009] Compared with the prior art, the steel plate hoisting device provided by this utility model has the following advantages: Firstly, it includes a hoisting rope with a lifting ring at the top and a hook with a hook frame. The hoisting rope is one piece, and the hook frame and hook are two. The hook frame includes a first rotating wheel, a second rotating wheel, and a side guard plate. The hoisting rope passes around the first rotating wheel, and the hook is fixed to the second rotating wheel. A support sleeve is fitted on the outside of the hoisting rope between the two hook frames. After the steel plate is hoisted, the hook is removed from the steel plate. The two hooks move towards the middle under their own weight. When the hook frame contacts the support sleeve, the hook frame stops moving towards the middle. When hoisting the steel plate again, it is only necessary to pull the hooks at both ends of the support sleeve a small distance to hang them on both sides of the steel plate. The support sleeve is located between the two hook frames, the hook movement distance is short, the labor intensity is low, and the efficiency is high. When hoisting the steel plate, the hooks are hung on both sides of the steel plate, the hoisting rope is triangular, and the two hook frames and hooks generate... Firstly, the force acting in the middle direction prevents the hook from falling off the steel plate. Secondly, because the support sleeve has tension springs at both ends, when lifting the steel plate, the hooks are hung on both sides of the steel plate, and the lifting rope forms a triangle. The two hook frames and the hooks generate a force acting in the middle direction, compressing the tension springs and preventing the hooks from falling off the steel plate. After the steel plate is lifted, the hooks are removed from the steel plate. After the external force is removed, the tension springs stretch due to their own elasticity, and the two hooks hardly move inward. When lifting the steel plate again, the hooks at both ends of the tension springs can be hung on both sides of the steel plate with almost no movement, resulting in less labor intensity and higher efficiency. Thirdly, because a top cup is provided on the side of the tension spring near the hook frame, and both ends of the tension spring are fixed to the support sleeve and the top cup respectively, it is more convenient to use. Fourthly, because the support sleeve includes two mating half-sleeves, different lengths of support sleeves can be replaced according to the width of the steel plate, making the application range wider.

[0016] The structure and operating principle of the steel plate hoisting device of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1 and Figure 2 The diagram shows the structure of the steel plate hoisting device of this utility model. The device includes a hoisting rope 2 with a lifting ring 1 at the top and a hook 4 with a hook frame 3. There is one hoisting rope 2, and two hook frames 3 and two hooks 4. The hook frame 3 includes a first rotating wheel 31, a second rotating wheel 32, and a side guard plate 33. The hoisting rope 2 passes over the first rotating wheel 31, and the hook 4 is fixed to the second rotating wheel 32. A support sleeve 5 is fitted over the outside of the hoisting rope 4 between the two hook frames 3.
[0018] After the steel plate is hoisted, the hooks 4 are removed from the steel plate 10. Under their own weight, the two hooks 4 move towards the middle along the hoisting rope 2. When the hook frame 3 contacts the support sleeve 5, the hook frame 3 stops moving towards the middle. When hoisting the steel plate again, the hooks 4 at both ends of the support sleeve 5 only need to be pulled to the sides of the steel plate by a small distance. The support sleeve 5 is located between the two hook frames. The hooks 4 move a short distance, with low labor intensity and high efficiency. When hoisting the steel plate, the hooks are hung on both sides of the steel plate. The hoisting rope is triangular. The two hook frames 3 and the hooks 4 generate a force in the middle direction, which prevents the hooks from falling off the steel plate.
[0019] like Figure 3 As shown, tension springs 6 are installed at both ends of the support sleeve 5. When hoisting the steel plate, the hooks 4 are hung on both sides of the steel plate, and the hoisting rope 2 is triangular. The two hook frames 3 and the hooks 4 generate a force in the middle direction, which compresses the tension springs 6 and prevents the hooks from falling off the steel plate. After the steel plate is hoisted, the hooks 4 are removed from the steel plate. After the external force is removed, the tension springs 6 stretch due to their own elasticity, and the two hooks 4 hardly move inward. When hoisting the steel plate again, the hooks 4 at both ends of the tension springs 6 can be hung on both sides of the steel plate with almost no movement, which reduces labor intensity and increases efficiency.
[0020] like Figure 4 As shown, a top cup 7 is provided on the side of the tension spring 6 near the hook frame. The two ends of the tension spring 6 are fixed to the support sleeve 5 and the top cup 7 respectively, which avoids the end of the tension spring from hanging on the hook frame 3, making it more convenient to use.
[0021] like Figure 5 and Figure 6As shown, the support sleeve 5 includes two mating half sleeves 51, which can be fixedly connected by fastening bolts 52. Depending on the width of the steel plate, support sleeves 5 of different lengths can be replaced, making the replacement of the support sleeve more convenient and its application range wider.
[0022] The scope of protection of this utility model is not limited to the above embodiments. Any structure that is the same as or similar to the structure of the steel plate hoisting device of this utility model falls within the scope of protection of this utility model.
