[0021] 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.
[0022] Reference Figures 1-3 The present invention provides an embodiment of a multi-functional hoisting hook for building construction, comprising a mounting base 1, a hook 5 fixedly connected to the bottom end of the mounting base 1, an obstruction member provided on the outer wall of the hook 5, the obstruction member comprising a fixing block 6 fixedly connected to both the front and rear ends of the hook 5, a locking block 8 rotatably connected to the inward end of the fixing block 6, a torsion spring 7 fixedly connected to both the front and rear ends of the locking block 8, the outward end of the torsion spring 7 being fixedly connected to the inward end of each of the two fixing blocks 6, and the free end of the locking block 8 being in contact with the inner wall of the right end of the hook 5;
[0023] Specifically, when using the hoist to transport small, non-shaking objects, the locking block 8 can be pushed to rotate, causing the hook 5 to open and the rope with the object attached can be put on the hook 5. Then, the locking block 8 will be reset under the elastic force of the torsion spring 7 and pressed against the inner wall of the hook 5, closing the opening and ensuring that the rope will not slip off the hook 5 during transportation.
[0024] Two wire-laying slots 13 are provided at both ends of the mounting base 1. Fixing plates 9 are fixedly connected to both ends of the mounting base 1. Guide components are provided at the top of each fixing plate 9. Each guide component includes two fixing blocks 12 fixedly connected to the front and rear sides of the top of the fixing plate 9. Guide rollers 11 are rotatably connected to one end of each adjacent fixing block 12. Two rotating shafts 17 are rotatably connected to the inner wall of the front end of the mounting base 1. Limiting components are provided at the front ends of each rotating shaft 17. Each limiting component includes a spring 18 fixedly connected to the front end of each rotating shaft 17. A sleeve 3 is fixedly connected to the front end of each spring 18. The outer walls of the sleeves 3 are fixed... A handwheel 2 is connected, and a limit rod 4 is fixedly connected to the rear end of the handwheel 2. The inner wall of the sleeve 3 is slidably connected to the outer wall of the rotating shaft 17. The outer wall of the limit rod 4 is set on the inner wall of the front end of the mounting base 1. Two fixing blocks 3 16 are fixedly connected to the front and rear sides of the outer wall of the rotating shaft 17. A winding post 15 is fixedly connected between two adjacent fixing blocks 3 16 on the front and rear sides of the outer wall of the rotating shaft 17. A rope 14 is wound on the outer wall of the winding post 15. A hook 10 is fixedly connected to the free end of the rope 14. The inner end of the fixing block 3 16 is fixedly connected to the inner wall of the mounting base 1. The lower side of the outer wall of the rope 14 is set at the top of the guide roller 11.
[0025] Specifically, when it is necessary to hoist a bundled long strip of building material, first hook 5 onto the middle of the building material, then pull the two handwheels 2 to pull the limit rod 4 out of the mounting base 1, release the tension spring 18 to release the limit of the handwheel 2, allowing the winding column 15 to rotate. Then pull the hook 10 to pull the rope 14 out of the mounting base 1 along the wire release groove 13, and then hook the two pairs of hooks 10 onto the left and right binding points at the top of the building material. Release the handwheel 2 to allow the limit rod 4 to lock back into the inner wall of the mounting base 1, re-limiting the rotating shaft 17, and cooperating with the hook 5 to hoist the building material. The materials are restricted to ensure that they do not sway significantly in the vertical direction during hoisting, thus preventing them from slipping and causing accidents. After hoisting, the handwheel 2 is pulled and rotated again, causing the shaft 17 to drive the winding column 15 inside the mounting base 1 to rotate. This allows the hook 10 to be retrieved, so that the rope 14 is wound around the winding column 15. The guide roller 11 fixed on the fixing block 2 12 can guide the rope 14 and prevent the rope 14 from entering from the corner of the wire release groove 13 due to the gravity of the hook 10, thus preventing wear on the rope 14 and extending the service life of the device.
[0026] Working principle: In daily use, the rope loop with the object attached is directly placed inside the hook 5. The locking block 8, together with the torsion spring 7, seals the opening of the hook 5, preventing the rope loop from falling off the hook 5 during hoisting. When transporting a large number of long strip building materials, first, the steel rope binding the middle of the building material is looped into the hook 5. Then, the handwheel 2 is pulled to disengage the limit rod 4 from the mounting base 1, releasing the limit on the winding post 15. Next, the locking hook 10 can be pulled to pull the rope 14 out from inside the mounting base 1, extending the range of motion of the locking hook 10. Then, the two pairs of locking hooks 10 are hooked onto the steel rope binding at both ends of the building material, forming a quadrilateral structure. The handwheel 2 is released to lock the limit rod 4 back in, thus restricting the vertical direction of the building material during hoisting, preventing large-scale swaying, and avoiding the phenomenon of the building material slipping out of the binding steel rope and causing an accident.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
