Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a heavy lifting device for construction. Background Technology

[0002] A heavy-duty hoist is a lifting mechanism that transports objects from the ground to a high altitude. It is often used in construction to transport building materials, construction equipment, or construction workers. Currently, after the heavy-duty hoist lifts the items to a high altitude, the heavy objects still need to be manually pulled to unload them to a designated location, which is time-consuming, labor-intensive, and poses safety risks. Therefore, there is a need for a hoist that can safely unload heavy objects. Utility Model Content

[0003] The purpose of this utility model is to provide a heavy lifting device for construction, which can reduce the burden of manual handling, reduce safety risks, and has a simple structure and is easy to use.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a construction heavy lifting device, comprising a base, a support column vertically mounted on the base, a telescopic column slidably connected to the support column, and a placement mechanism mounted on the outer side of the telescopic column. The telescopic column is equipped with a linear drive mechanism connected to the support column. The linear drive mechanism includes a linear hydraulic rod, a sliding block, a slide rail, and a push plate. The slide rail is installed between the inner side of the support column and the outer side of the telescopic rod, and is fixed to the support column. The sliding block is fixed to the telescopic rod and slidably connected along the slide rail. The linear hydraulic rod is fixed to the bottom end of the support column, and the top end of the linear hydraulic rod is connected to the push plate, which is fixed to the telescopic column. The placement mechanism is located directly above the base, and rollers are also provided at the four corners of the base.

[0005] Furthermore, the storage mechanism includes a hanging bracket fixed on the telescopic column, a load-bearing plate parallel to the base connected to the hanging bracket, a fence provided on the outside of the load-bearing plate, a pushing mechanism provided at one end of the load-bearing plate near the telescopic column, and a sliding mechanism slidably connected to the load-bearing plate at the front end of the pushing mechanism.

[0006] Furthermore, the pushing mechanism includes a linear motor and a pusher block. The tail of the linear motor is fixed to the side wall of the load-bearing plate, and the head is connected to the pusher block. The linear motor is electrically connected to an external drive to control the extension and retraction of the pusher block's sliding mechanism.

[0007] Furthermore, the sliding mechanism includes a loading plate, a railing, and rollers. A set of rollers is fixedly connected to the outer wall of the loading plate, and the loading plate is slidably connected to the load-bearing plate through the rollers. A protective railing is installed on the outer side of the loading plate.

[0008] The beneficial effects of this utility model are: 1) This utility model uses a linear drive mechanism to control the lifting and lowering of the telescopic column, so that the placement mechanism can reach the predetermined height. The placement mechanism carries the heavy object. After it reaches the predetermined height, the pushing mechanism and the sliding mechanism work together to push the heavy object outward from the loading plate to the designated location. This can reduce the burden of manual handling and is simple in structure and easy to use. Attached Figure Description

[0014] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0015] Example: As shown in the figure, the construction heavy lifting device of this utility model includes a base 1, a support column 2 vertically installed on the base 1, a telescopic column 3 slidably connected to the support column 2, and a placement mechanism 4 installed on the outer side of the telescopic column 3. The telescopic column 3 is provided with a linear drive mechanism 5 connected to the support column 2. The linear drive mechanism 5 includes a linear hydraulic rod, a sliding block, a slide rail, and a push plate. The slide rail is installed between the inner side of the support column 2 and the outer side of the telescopic rod, and the slide rail is fixed to the support column 2. The sliding block is fixed to the telescopic rod and slides along the slide rail. The linear hydraulic rod is fixed to the bottom end of the support column 2, and the top end of the linear hydraulic rod is connected to the push plate. The push plate is fixed to the telescopic column 3. The placement mechanism 4 is located directly above the base 1. Rollers 15 are also provided at the four corners of the base 1.

[0016] The storage mechanism 4 includes a hanging bracket 6 fixed on the telescopic column 3. A load-bearing plate 7 parallel to the base 1 is connected to the hanging bracket 6. A fence 8 is provided on the outside of the load-bearing plate 7. A pushing mechanism 9 is also provided at one end of the load-bearing plate 7 near the telescopic column 3. A sliding mechanism 10 that is slidably connected to the load-bearing plate 7 is also provided at the front end of the pushing mechanism 9.

The tail of the linear motor 11 is fixed to the side wall of the load-bearing plate 7, and the head is connected to the pusher block 12.
