Description

Technical Field

[0001] This utility model relates to the field of steel structure unhooking, specifically a high-altitude unhooking device for steel structures. Background Technology

[0002] In steel structure construction, hoisting is a crucial step. Hoisting operations are typically carried out when prefabricated steel components need to be moved from the ground or other locations to their designed positions for precise installation, such as steel space frame structures and crane beams. The hoisting process for these components is usually more complex, requiring more precise hoisting techniques and equipment.

[0003] Currently, during the steel structure installation process, after the erection of tall structures is completed, the lifting points are tens of meters above the ground. Manual climbing and unhooking pose safety hazards. In addition, due to the height of the lifting points above the ground, manual climbing is required to repeatedly lift and unhook several installation points, resulting in low efficiency.

[0004] Therefore, a high-altitude unhooking device for steel structures is proposed to address the above problems. Utility Model Content

[0018] 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 scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figures 1 to 4As shown in the embodiment of this utility model, a high-altitude unhooking device for steel structures includes an installation strip frame 1. The device is characterized by: two symmetrically distributed movable plates 2 slidingly connected inside the installation strip frame 1; a guide groove 3 being provided on the inner side of each movable plate 2; a connecting rod 4 fixedly connected to the bottom of each movable plate 2; a clamping plate 5 fixedly connected to the end of each connecting rod 4; a transverse groove 6 being provided at the bottom of the installation strip frame 1; the connecting rod 4 and the transverse groove 6 being slidably connected; a guide rod 7 slidingly connected inside the guide groove 3; two symmetrically distributed vertical grooves 8 being provided on both sides of the installation strip frame 1; the guide rod 7 and the vertical groove 8 being slidably connected; and a... Locking assembly 9; a reinforcing rod 10 is fixedly connected to the top of adjacent guide rods 7; a pressure plate 12 is fixedly connected between a pair of reinforcing rods 10; a hook 13 is fixedly connected to the top of the pressure plate 12; the locking assembly 9 includes a fixing plate 91; the fixing plate 91 is fixedly connected to one side of the mounting strip frame 1; a telescopic rod 92 is slidably connected and passes through the middle of the fixing plate 91; a snap-fit ​​plate 93 is fixedly connected to one side of the moving plate 2 near the fixing plate 91; a through groove 14 is opened on the side of the mounting strip frame 1 near the snap-fit ​​plate 93; the snap-fit ​​plate 93 and the through groove 14 are slidably connected; a slot 94 is opened at the top of the snap-fit ​​plate 93; the telescopic rod 92 and the slot 94 are slidably engaged; the bottom of the telescopic rod 92... A fixing block 97 is fixedly connected; a spring 96 is fixedly connected between the fixing plate 91 and the fixing block 97; the spring 96 is sleeved on the surface of the telescopic rod 92; when the structural component is hoisted to a high altitude, by placing the structural component between the two clamping plates 5, then lifting the telescopic rod 92 upwards and compressing the spring 96, the bottom end of the telescopic rod 92 is pulled out from the inside of the slot 94, releasing the restriction on the movement of the moving plate 2 to the side closer to each other. Then, the device is lifted upwards, and under the action of its own gravity, the moving plate 2 is pushed to move simultaneously to the side closer to each other by the cooperation between the guide groove 3 and the guide rod 7, thereby driving the clamping plate 5 to move towards one side of the structural component, clamping and fixing the structural component, and with the weight of the structural component... As the connecting rod 4 is added, the downward pulling force gradually increases. Under the cooperation of the guide groove 3 and the guide rod 7, the two clamping plates 5 are forced to squeeze to one side of the structural component, thereby gradually increasing the friction between the clamping plates 5 and the structural component, thus enabling stable clamping of the structural component. When unloading, when the pulling force on the pressure plate 12 disappears, the pressure plate 12 moves downward under the action of gravity, thereby simultaneously pushing the two moving plates 2 to move away from each other. When the snap-fit ​​plate 93 moves to contact the telescopic rod 92, it pushes the telescopic rod 92 to move upward and compresses the spring 96, so that the bottom end of the telescopic rod 92 is inserted into the slot 94, thereby locking the opening of the clamping plate 5 and completing the automatic buckling.By incorporating locking component 9, the device can quickly lock and unlock clamping plate 5, simplifying the operation of unhooking during component hoisting, improving the convenience of hook and release, and enhancing the safety of steel structure hoisting.

[0021] Please see Figure 3 As shown, a pull rod 95 is fixedly connected to the top of the telescopic rod 92; the pull rod 95 is located on the top of the fixed plate 91; by setting the pull rod 95, when the structural component is installed on the device, the telescopic rod 92 can be lifted by manipulating the pull rod 95, so as to easily lift the telescopic rod 92 upward and complete the unlocking operation of the moving plate 2.

[0022] Please see Figure 1 and Figure 2 As shown, a rubber pad 11 is fixedly connected to the middle of the clamping plate 5; the rubber pad 11 is made of rubber; by setting the rubber pad 11, the friction between the clamping plate 5 and the clamped object is increased, thereby improving the stability of clamping.

[0023] Working Principle: In steel structure engineering, when hoisting structural components to a high altitude, the component is placed between two rubber pads 11. Then, the tie rod 95 is lifted upwards, simultaneously moving the telescopic rod 92 and the fixing block 97 upwards, compressing the spring 96. This causes the bottom end of the telescopic rod 92 to be pulled out of the slot 94, releasing the restriction on the movement of the moving plate 2 towards the side closer to each other. Then, the device is lifted upwards, and under its own weight, the guide groove 3 and guide rod 7 work together to push the moving plate 2 towards the side closer to each other. This causes the clamping plate 5 to move towards one side of the structural component, clamping and fixing it. Furthermore, as the weight of the structural component increases, the connecting rod 4... As the downward pulling force gradually increases, the two clamping plates 5 are forced to press against one side of the structural component under the cooperation of the guide groove 3 and the guide rod 7. This causes the friction between the rubber pad 11 and the structural component to gradually increase, thereby enabling stable clamping of the structural component. During unloading, when the pulling force on the pressure plate 12 disappears, the pressure plate 12 moves downward under the action of gravity, thereby simultaneously pushing the two moving plates 2 to move away from each other. When the locking plate 93 moves to contact the telescopic rod 92, it pushes the telescopic rod 92 to move upward and compresses the spring 96, so that the bottom end of the telescopic rod 92 is inserted into the slot 94, thereby locking the opening of the clamping plate 5 and completing the automatic unhooking.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
