Description

Technical Field

[0001] This utility model belongs to the field of automation technology, and in particular relates to a heavy-duty lifting platform. Background Technology

[0002] Lifting platforms are very important production tools in machining or manufacturing. They are key tools for lifting heavy equipment and play a vital role in the convenience and efficiency of production and processing.

[0003] While current lifting platforms can achieve some results, they have the following problems: 1. The lifting capacity is limited, making it unsuitable for heavy components; 2. Currently, the lifting platform does not have a fall protection design. If an accident occurs and the lifting mechanism fails, the platform will fall rapidly, resulting in losses. 3. The lifting platform has no sealing design around it. In order to lift large parts, the lifting platform will leave a large gap. When it is lifted or lowered, there is no sealing structure. The large hole is very dangerous and also not conducive to close-range maintenance and inspection. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A heavy-duty lifting platform includes a lifting platform composed of several lifting mechanisms, wherein the lifting platform is provided with interconnected ventilation pipes. The lifting mechanism includes a frame body and a lifting assembly and a sealing assembly installed on the frame body. The lifting assembly is used to move parts up / down, and the sealing assembly is used to close the gap in the frame body when the lifting assembly stops.

[0005] Furthermore, the lifting assembly includes a lifting frame and a platform that slides on the lifting frame, and a first driving element that drives the platform to slide up / down within the lifting frame is also installed on the lifting frame.

[0006] Furthermore, the sealing assembly consists of several sealing units installed on the frame body, with the several sealing units arranged along the central circumference of the lifting assembly, and the lifting assembly placed within the enclosure formed by the several sealing units.

[0007] Furthermore, the platform is also equipped with a fall protection structure, which includes a rack on the lifting frame and a buckle rotatably connected to the platform. The lifting frame is also equipped with a second driving element that drives the buckle to rotate. When the buckle is rotated, the buckle moves closer to or away from the rack, which can restrict or release the platform.

[0008] Furthermore, the sealing unit is provided with a plurality of parallel sealing plates and a third driving element for driving the sealing plates to move. The third driving element can drive the sealing plates to move closer to / away from the lifting assembly.

[0009] Furthermore, the first driving element is a motor and a lead screw drive, and the first driving element is respectively located at the four corners of the lifting frame. The moving end of the lead screw drive is fixedly connected to the platform.

[0010] The beneficial effects of this utility model are: 1. This utility model uses four sets of drive mechanisms, distributed at the four corners of the frame. The four drive mechanisms lift and lower simultaneously, greatly improving the lifting force.

[0011] 2. This utility model has a buckle mechanism on the platform. The buckle mechanism can match the rack on the frame body. However, in case of an accident, the buckle mechanism will engage the rack to prevent the platform from falling and causing damage.

[0012] 3. This utility model is equipped with several sealing plates. When the part is raised or lowered, the sealing plates can seal the part according to its shape, avoiding large holes, improving safety, and facilitating close-range inspection by staff. Attached Figure Description
