Description

Technical Field

[0001] The utility model relates to a hoisting device, and more specifically to a hoisting device for H-shaped steel members. Background Art

[0002] Steel members refer to steel structure composite members that can bear and transfer loads, which are connected by steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels through cold bending or welding and connectors. The steel member system has comprehensive advantages such as light self-weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution.

[0003] In the patent publication number CN210084742U, a hoisting device for H-shaped steel members is disclosed, belonging to the technical field of steel member construction. The end hoisting and middle hoisting of the H-shaped steel member are realized through the end hoisting tool and the middle hoisting tool, ensuring the balanced force during the hoisting of the H-shaped steel member and improving safety. The H-shaped steel member is reinforced and anti-slip by using a clamping plate, further improving safety and avoiding slipping. Moreover, when the end hoisting tool and the middle hoisting tool hoist the H-shaped steel member, the hoisting method is convenient and fast, improving the work efficiency of the staff.

[0004] However, due to the different sizes of different H-shaped steel members, multiple adjustments or other fillers are required to ensure stable clamping, and after clamping, it is easy to fall during movement and cause injury due to the lack of support at the bottom. Summary of the Utility Model

[0005] The main technical problem to be solved by the utility model is to provide a hoisting device for H-shaped steel members, which can solve the problems of different sizes of different steel members and difficult fixed clamping, and can form a support for the steel members to avoid falling off.

[0006] To solve the above technical problems, according to one aspect of the utility model, more specifically, a hoisting device for H-shaped steel members includes a moving device. A lifting device is fixedly connected to the right side of the moving device. A hoisting platform is fixedly connected to the right side of the lifting device. Clamping plates are arranged on both sides of the hoisting platform. A through transmission hole is opened on both sides of the hoisting platform. A sleeve ring is fixedly connected inside the transmission hole. An internal thread cylinder is rotatably connected inside the sleeve ring. A threaded rod is threadedly connected inside the internal thread cylinder. The opposite ends of the threaded rod are fixedly connected to the opposite ends of the clamping plate. A motor slot is arranged inside the hoisting platform. A first motor is fixedly connected inside the motor slot. A first gear is fixedly connected to the output shaft of the first motor. A second gear is fixedly connected to the outer side wall of the internal thread cylinder. The first gear is meshed with the second gear.

[0007] Furthermore, a lower-layer protection device is rotatably connected to the bottom end of the clamping plate. The lower-layer protection device includes a closing plate, a locking part, a clamping groove, a telescopic rod, and a sliding device. The closing plate is rotatably connected to the bottom end of the clamping plate. The locking parts are fixedly connected to the opposite sides of the two closing plates. A through-type clamping groove is formed in the outer side wall of the closing plate. The telescopic rod is fixedly connected to the inside of the clamping groove. The sliding device is slidably connected to the inside of the clamping groove.

[0008] Furthermore, the sliding device includes a direction block, a second motor, and a sliding rod. The second motor is fixedly connected to the inside of the direction block. The sliding rod is fixedly connected to the output shaft of the second motor.

[0009] Furthermore, a flip cover plate is rotatably connected to the outer side wall of the sliding rod. An auxiliary plate is fixedly connected to the outer side wall of the flip cover plate.

[0010] Furthermore, universal wheels are fixedly connected to the lower surface of the moving device.

[0011] Furthermore, a friction pad is fixedly connected to the outer side wall of the auxiliary plate.

[0012] The beneficial effects of the hoisting device for H-shaped steel members of the present utility model are as follows:

[0013] The steel member is locked and transported through the provided moving device, lifting device, and lifting platform. The clamping plates on both sides of the lifting platform are used to clamp steel members of different sizes. The bottom is supported and protected by the lower-layer protection device. The inner side of the steel member is clamped by the sliding rod and the flip cover plate, avoiding the danger caused by the overweight of the steel member falling off during hoisting, enhancing the working efficiency during hoisting, and being applicable to different steel members;

[0014] By setting the first motor to drive the first gear and the second gear to rotate, the internal thread cylinder rotates, and then the two threaded rods move relatively or away from each other, thereby realizing the relative movement of the clamping plates and adjusting different sizes for different steel members. By setting the second motor to drive the flip cover plate to rotate, the auxiliary plate is used to extrude the steel member. BRIEF DESCRIPTION OF THE DRAWINGS
