Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel plate hoisting, and specifically designs a steel plate hoisting device. Background Art
[0002] Steel plate is a common raw material used to make steel products. When using steel plate as raw material to process workpieces, the steel plate needs to be moved from the stacking location to the processing location. Due to the large area and weight of the steel plate, manual transportation is very inconvenient and a lifting device must be used.
[0003] When moving steel plates, the traditional method is to set two single hook claws at the bottom of the lifting device. To ensure the strength and stability of the hook claws, the hooking end of the hook claw is set with a blunt head. Then the hook claw is manually hooked to the bottom of the steel plate, and the steel plate is lifted by a crane to move the steel plate. When one or more steel plates need to be moved from the stack, the steel plate to be lifted is manually lifted with a steel chisel, and then the hook claw is hooked in to complete the lifting. This method of manually lifting the steel plate is laborious and inefficient. Utility Model Content
[0004] The utility model aims to provide a steel plate lifting device, which has strong lifting stability and is convenient for lifting a single piece or a specified number of steel plates on overlapping steel plates, saving time and labor and improving production efficiency.
[0005] The utility model solves the technical problem by adopting the following technical solution: a steel plate lifting device, comprising a lifting rope and two hooks, wherein the hooks comprise two single hooks with the same structure and arranged side by side, a connecting rib is arranged between the two single hooks, and a connecting shaft is arranged at the top of the connecting rib near the top between the two single hooks; the hooking end of the single hook is a flat tip. The two hooks are hung on the same lifting rope through the connecting shaft, and the two hooks can be close to or away from each other on the lifting rope.
[0006] Furthermore, the hooking end includes an inner hook surface and an outer hook surface. When the hook claw is suspended and naturally hangs down, the inner hook surface is a horizontal surface, and the outer hook surface is an inclined surface.
[0007] Furthermore, the hook is connected to the suspension rope via a pulley.
[0008] Furthermore, a bearing is sleeved on the connecting shaft.
[0009] Furthermore, the connecting ribs include two connecting ribs, and the connecting axis and the two connecting ribs are evenly distributed.
[0010] Furthermore, the suspension rope is a steel wire rope.
[0011] The beneficial effects solved by the utility model are as follows: the hook claw is composed of two side-by-side single hook claws, and the hooking end of the hook claw is set as a flat tip, which not only enhances the stability of the lifting, but also makes it unnecessary to lift the steel plate before lifting the hook claw when hooking the stacked steel plate. Since the two hook claws can be close to or away from each other on the lifting rope, it is only necessary to manually hook the hook claw in the gap between the steel plates and lift it upward by the lifting rope; under the action of the steel plate and its own weight, the two hook claws are close to each other to squeeze into the gap, and the lifting can be started without manually lifting the steel plate. And because the hook claw is composed of two single hook claws, the strength of the two single hook claws is superimposed, and the middle is strengthened by connecting ribs, so that the strength of the double hook claw 1 is much greater than that of the single hook claw 1, even if the hooking end is a flat tip, its strength is still sufficient and will not cause deformation of the hooking end. The utility model has a simple structure, strong lifting stability, and is convenient for lifting a single piece or a specified number of steel plates on overlapping steel plates, saving time and labor, and improving production efficiency.

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0017] See also Figure 1-3 A steel plate lifting device is shown, comprising a lifting rope 2 and two hooks 1, wherein the hook 1 comprises two single hooks with the same structure and arranged side by side, and a connecting rib 3 is arranged between the two single hooks to connect the two single hooks, so that the two single hooks are connected as a whole and the strength of the hook 1 is increased, and a connecting shaft 4 is arranged at the upper part of the connecting rib 3 near the top between the two single hooks, and the connecting shaft 4 is used to connect with an external lifting device and also can enhance the strength of the hook 1; the hooking end of the single hook is a flat tip; there is generally a small gap after the steel plates are stacked, and the hooking end is set as a flat tip to facilitate the insertion of the hook 1 into the gap of a single or multiple overlapping steel plates.
[0018] The two hooks 1 are hung on the same suspension rope 2 through the connecting shaft 4, and the two hooks 1 can move closer to or farther away from each other on the suspension rope 2. In this way, when the hooks 1 grab the steel plate, the two hooks 1 automatically move closer to clamp the steel plate.
[0019] The hook 1 is composed of two side-by-side single hook claws, and the hooking end of the hook claw 1 is set to a flat tip, which not only enhances the stability of the lifting, but also allows the hook claw 1 to hook the stacked steel plates without lifting the steel plates. Since the two hook claws 1 can be close to or away from each other on the lifting rope 2, it is only necessary to manually hook the hook claw 1 in the gap between the steel plates and lift it upward by the lifting rope 2; under the action of the steel plates and their own weight, the two hook claws 1 are close to each other to squeeze into the gap, and the lifting can be started without manually lifting the steel plates. And because the hook claw is composed of two single hook claws 1, the strength of the two single hook claws 1 is superimposed, and the middle is strengthened by the connecting rib 3, so that the strength of the double hook claw 1 is much greater than that of the single hook claw 1, even if the hooking end is a flat tip, its strength is still sufficient and will not cause deformation of the hooking end. The utility model has a simple structure, strong lifting stability, and is convenient for lifting a single piece or a specified number of steel plates on overlapping steel plates, saving time and labor, and improving production efficiency.
[0020] Furthermore, the hook end includes an inner hook surface 5 and an outer hook surface 6. When the hook claw 1 is suspended and naturally droops downward, the inner hook surface 5 is a horizontal surface, and the outer hook surface 6 is an inclined surface. The outer hook surface 5 is an inclined surface, which facilitates the hook claw 1 to be inserted into the gap of the steel plate. The inner hook surface 5 is a horizontal surface. When the hook claw 1 lifts the steel plate, the inner hook surface 5 contacts the bottom surface of the lowest steel plate, and the inner hook surface is horizontal, so that the contact surface between the hook and the steel plate is closer, which can increase the lifting stability.
[0021] Furthermore, the hook 1 is connected to the suspension rope 2 through a pulley. This makes the friction between the hook 1 and the suspension rope 2 smaller when the hook 1 is moving away from or approaching, reduces the friction between the suspension rope 2 and the hook 1, and increases its service life; and it is more labor-saving when manually pulling the two hooks 1 apart to grab the steel plate.
[0022] Furthermore, a bearing is sleeved on the connecting shaft 4. This makes the friction between the hook 1 and the rope 2 smaller when the hook 1 is moving away from or approaching, reduces the friction between the rope 2 and the hook 1, and increases its service life; and it is more labor-saving when manually pulling apart the two hooks 1 to grab the steel plate.
[0023] Furthermore, the connecting ribs 3 have two connecting ribs 3, and the connecting shaft 4 and the two connecting ribs 3 are evenly distributed. As the number of connecting ribs 3 increases, the strength of the hook 1 is enhanced.
[0024] Furthermore, the hoisting rope 2 is a steel wire rope. The steel wire rope has low friction, high strength and good flexibility. Since the steel plate has a large mass during the hoisting process, the hoisting rope 2 made of general materials will have a risk of breaking. The use of steel wire rope makes hoisting safer.
[0025] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the scope of the utility model should be included in the protection scope of the utility model.
