| Technical Elements to Realize 2t Lifting Clean Room Crane
In the field of hoisting machinery, clean room cranes are a relatively common hoisting machinery. Now, clean room cranes are generally used to lift heavy objects. When lifting heavy objects on 2t clean driving, pull the hand clockwise to make the hoist chain and sprocket rotate, and make the ratchet and brake seat of the friction plate rotate together, then the tooth long axis is the toothed plate gear, the tooth short axis and the spline hole descend When the hoist chain is pulled counterclockwise, the brake pads are separated from the brake pads, the ratchet wheel is stationary under the action of the ratchet wheel, and the five-tooth long shaft makes the lifting sprocket move in the opposite direction, so that the heavy object can be smoothly lowered.
However, when such a clean room is used to hoist a crane to lift heavy objects, since there is no guide mechanism provided on the hoist chain for carrying the heavy objects, the hoist chain will shake during the lifting process. Moreover, the heavy objects will also shake together with the hoist chain, which is not conducive to the correct positioning of the heavy objects in a static state, which is a serious safety hazard. In addition, the conventional lifting mechanism does not take dust-proof measures, and there is a dust problem during long-term use, which makes it difficult to apply to an industrial production environment with strict requirements on cleanliness. Therefore, it is urgent to propose a hoisting mechanism for a clean room and a hoisting device equipped with the hoisting mechanism, so that the problem that the clean room hoisting mechanism cannot be accurately positioned in a static state is suitable for the industrial production environment with strict requirements of the clean room, so that the Effective solution in industrial production environment.
1. Technical problems to be solved
In order to solve the above problems, the new type has a simple structure and can be applied to an industrial production environment with high cleaning requirements, effectively solving the problem that the existing hoisting mechanism in the industrial production environment cannot be accurately positioned when the hoisted heavy objects are stationary, and has The hoisting machinery of the hoisting mechanism.
2. Technical solutions
In order to achieve the purpose, the clean room hoisting crane adopts the following main technical solutions. The utility model is equipped with longitudinally arranged guide rails, a lifting trolley for hoisting heavy objects, and a lifting hoist for controlling the lifting and lowering of the lifting trolley. The top of the guide rail is connected with an upper fixing seat, and the lifting hoist is suspended on the fixing seat to provide a clean room. Using the lifting mechanism, the lifting trolley is connected with the lifting trolley through the hoist chain, the lifting trolley has a pair of guide wheels, the guide wheels are rollingly arranged in the guide rail, and the lifting trolley is connected with the guide rail through the guide wheel. A dust-proof device is provided on the outer cover of the hoisting trolley in the clean room, the hoist chain is arranged in the telescopic organ cover, and the outer cover of the lifting trolley is provided with a dust-proof device.
