Description

Technical Field

[0001] This invention relates to the field of power distribution station construction, and in particular to a material hoisting device for construction sites. Background Technology

[0002] A distribution station is a site that delivers electricity to electrical equipment or users. Located at the end of the power grid, it is a point on a radial network, connecting to substations upstream and various electrical equipment downstream. During the construction of a distribution station, large materials such as transformer boxes need to be lifted using cranes.

[0003] However, existing hoisting equipment typically uses four ropes with hooks or suction cups for suspension when hoisting materials such as transformer boxes. The fixing method is relatively simple. Therefore, because the transformer box is heavy, if the speed is too fast, it will sway violently in mid-air, which can easily lead to the danger of falling.

[0004] In response to the aforementioned technical problems, the inventors have proposed a material hoisting device for construction sites. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a material hoisting device for construction sites.

[0006] The present invention provides a material hoisting equipment for construction sites, which adopts the following technical solution:

[0007] A material hoisting device for construction sites includes a hook, a suspension component at the lower end of the hook, and a stabilizing component at the lower end of the suspension component.

[0008] The suspension assembly includes an iron ring, a winding reel, and a steel wire rope. The iron ring is suspended on a hook. The winding reel is symmetrically mounted on both the left and right ends of the iron ring. The steel wire rope is wound on the winding reel and arranged symmetrically in pairs.

[0009] The stabilizing components include a top plate, support columns, a bottom plate, and a clamping unit. The top plate is located directly below the hook, and the upper end of the top plate is fixedly connected to the end of the wire rope. Four support columns are evenly installed at the lower end of the top plate, and the bottom end of the support columns is connected to the bottom plate. The clamping unit is also provided at the upper end of the top plate.

[0010] The clamping unit includes a gear, a rack, a drive handle, and a clamping rod. The gear is rotatably mounted on the upper end of the top plate via a rotating shaft. Both ends of the gear are meshed with racks, and the two racks are staggered. A clamping rod is installed at one end of each rack.

[0011] The inner end of the iron ring and the hook are attracted to each other by a magnetic material;

[0012] A guide block is fixedly installed at the lower end of the rack, and the guide block is slidably disposed in a guide groove opened on the upper surface of the top plate;

[0013] The clamping rod consists of a main rod, a secondary rod, and extrusion blocks. The upper end of the main rod is fixedly connected to the bottom end of the rack. The secondary rod is fixed to one side of the main rod and is evenly distributed from top to bottom. Several extrusion blocks are evenly installed on the end of the secondary rod near the gear.

[0014] The extrusion block is made of insulating material;

[0015] The support column consists of a core column and a sleeve rod. The top end of the core column is fixedly connected to the bottom end of the top plate, and the bottom end of the sleeve rod is fixedly connected to the top end of the bottom plate. The bottom end of the core column is slidably set inside the sleeve rod, and a support spring is fixedly connected between the bottom of the core column and the inner bottom wall of the sleeve rod.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1. This solution uses a manual rotating handle to drive the gear. The gear rotates, and with the cooperation of the guide block and guide groove, the gear drives two racks to move linearly back and forth. The racks drive the clamping rod to make synchronous linear motion, so that the clamping rod drives the pressing block to clamp and fix both ends of the wiring box or transformer box, achieving a stable effect.

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0024] This invention discloses a material hoisting device for construction sites. (Refer to...) Figures 1 to 4 A material hoisting device for construction sites includes a hook 1, a suspension component 2 at the lower end of the hook 1, and a stabilizing component 3 at the lower end of the suspension component 2.

[0025] The suspension assembly 2 includes an iron ring 20, a winding reel 21, and a steel wire rope 22. The iron ring 20 is suspended on the hook 1. The winding reel 21 is symmetrically mounted on the left and right ends of the iron ring 20. The steel wire rope 22 is wound on the winding reel 21. The steel wire rope 22 is arranged symmetrically in pairs. The inner end of the iron ring 20 and the hook 1 are attracted to each other by a magnetic material.

[0026] The stabilizing component 3 includes a top plate 30, support columns 31, a bottom plate 32, and a clamping unit 33. The top plate 30 is located directly below the hook 1, and the upper end of the top plate 30 is fixedly connected to the end of the wire rope 22. Four support columns 31 are evenly installed at the lower end of the top plate 30. The bottom end of the support columns 31 is connected to the bottom plate 32. The clamping unit 33 is also provided at the upper end of the top plate 30. The support column 31 is composed of a core column 310 and a sleeve rod 311. The top end of the core column 310 is fixedly connected to the lower end of the top plate 30, and the lower end of the sleeve rod 311 is fixedly connected to the upper end of the bottom plate 32. The lower end of the core column 310 is slidably disposed inside the sleeve rod 311, and a support spring 312 is fixedly connected between the bottom of the core column 310 and the inner bottom wall of the sleeve rod 311.

[0027] The clamping unit 33 includes a gear 330, a rack 331, a drive handle 332, and a clamping rod 333. The gear 330 is rotatably mounted on the upper end of the top plate 30 via a rotating shaft. Both ends of the gear 330 are meshed with racks 331, which are staggered. A clamping rod 333 is installed at one end of any rack 331. A guide block 334 is fixedly installed at the lower end of the rack 331. The guide block 334 is slidably mounted in a guide groove opened on the upper surface of the top plate 30. The clamping rod 333 consists of a main rod 335, a secondary rod 336, and pressing blocks 337. The upper end of the main rod 335 is fixedly connected to the bottom end of the rack 331. The secondary rod 336 is fixed to one side of the main rod 335 and is evenly distributed from top to bottom. Several pressing blocks 337 are evenly installed at the end of the secondary rod 336 near the gear 330. The pressing blocks 337 are made of insulating material.

[0028] The implementation principle of a material hoisting device at a construction site according to an embodiment of the present invention is as follows: First, the crane operator controls the hook 1 to move the suspension component 2 and the stabilizing component 3 to a suitable position and place and straighten them. Then, the distribution box or transformer box is placed between the top plate 30 and the bottom plate 32 by manual means. During this process, under the action of the support spring 312, the position of the top plate 30 adapts to the height of the distribution box. Finally, the handle is rotated manually to drive the gear 330. The gear 330 rotates, and with the cooperation of the guide block 334 and the guide groove, the gear 330 drives the two racks 331 to move linearly back and forth. The racks 331 drive the clamping rod to make synchronous linear motion, so that the clamping rod drives the pressing block 337 to clamp and fix the two ends of the distribution box or transformer box, achieving a stable effect and avoiding the danger of the distribution box or transformer box falling due to violent shaking in mid-air.
