Description

Technical Field

[0001] This utility model relates to the field of lifting equipment, and in particular to a dual-platform lifting mechanism. Background Technology

[0002] A hoisting platform is a large mechanical device that transports goods by changing potential energy, such as a mine hoist or a dam hoist. Hoists generally refer to large mechanical devices with high power and strong lifting capacity. They complete the transportation process by driving flexible steel wire ropes and the goods being transported up and down through power machinery. In a broad sense, elevators, overhead cranes, winches, jacks, hoists, gate hoists, etc. can all be called hoists. Hoists are divided into mine hoists, bucket elevators, etc.

[0003] Nowadays, industrial automation equipment has entered various factories. Most current platform lifting mechanisms are single platforms, which are insufficient in lifting effect and reduce the efficiency of material lifting. To address this issue, we propose a dual-platform lifting mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a dual-platform lifting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-platform lifting mechanism includes a base plate, a fixed frame mounted on the upper surface of the base plate, a controller mounted on the front of the fixed frame, a protective cover mounted on the upper surface of the fixed frame, a first lifting mechanism mounted inside the fixed frame, a second lifting mechanism mounted on the upper surface of the fixed frame, four casters mounted on the bottom surface of the base plate, and a support mechanism mounted on the upper surface of the base plate.

[0007] In a further embodiment, the first lifting mechanism includes a drive motor mounted on the upper surface of the base plate. A threaded rod is mounted on the output end of the drive motor. A bearing is fixedly embedded in the inner top wall of the fixed frame. The top end of the threaded rod is fixedly connected to the inner ring of the bearing. A positioning screw ring is threadedly connected to the outer surface of the threaded rod.

[0008] In a further embodiment, the inner sidewall of the fixing frame is provided with symmetrical sliding grooves, and a sliding plate is slidably connected inside each of the two sliding grooves. The sides of the two sliding plates that are close to each other are connected to the outer surface of the positioning screw ring. A fixing plate is fixedly connected to the left side of the positioning screw ring, and a first lifting platform is fixedly connected to the left side of the fixing plate.

[0009] In a further embodiment, the second lifting mechanism includes a forward and reverse motor, the output end of which is equipped with a winding wheel, the outer surface of which is provided with a lifting rope, and the bottom end of which is fixedly connected with a fixing hook.

[0010] In a further embodiment, a fixing ring is hung inside the fixing hook, and a positioning plate is fixedly connected to the bottom end of the fixing ring. Four connecting columns are fixedly connected to the bottom surface of the positioning plate, and a second lifting platform is fixedly connected to the bottom end of each of the connecting columns.

[0011] In a further embodiment, the support mechanism includes two through holes, symmetrical cylinders are mounted on the upper surface of the base plate, the output ends of the two cylinders are fixedly connected to support frames, and the bottom surfaces of the two support frames are fixedly connected to symmetrical anti-slip seats.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a drive motor to rotate a threaded rod. The threaded rod, along with a sliding groove and a sliding plate, moves a positioning screw ring up and down. This positioning screw ring then moves the first lifting platform up and down, lifting the material. A forward and reverse motor drives a take-up reel. The take-up reel, in conjunction with the lifting rope, moves the second lifting platform up and down, lifting the material. This dual-platform lifting effect improves material lifting efficiency. A cylinder pushes a support frame up and down. The support frame, along with an anti-slip seat, ensures stable placement of the device, preventing slippage. Attached Figure Description
