Brake device for pneumatic monorail hoist and use method thereof

Abstract

The invention discloses a brake device for a pneumatic monorail hoist. The brake device comprises the pneumatic monorail hoist, a mounting plate, brake mechanisms, a straightening mechanism and an alignment mechanism, the mounting plate is mounted on the bottom of the pneumatic monorail hoist, the multiple brake mechanisms are mounted on one side of the mounting plate, the straightening mechanismis mounted at the position, below the brake mechanisms, of one side of the mounting plate, the alignment mechanism is mounted on the bottom of the mounting plate, the brake mechanisms are mounted on the mounting plate for braking a sling, a first air pressure rod on a fixed frame shrinks to drive a lifting connecting plate to move towards a fixed frame, at the moment, a holding connecting rod is driven to rotate around a connecting pin, a holding clamping base connected with shaft connecting blocks on the two sides gets close to the sling until the sling is clamped to achieve braking through the holding clamping base, when the pneumatic monorail hoist drives the sling to ascend and descend, and emergency brake is carried out, it is ensured that a lifting object hangs at the fixed height, and application in actual operation is facilitated.

Description

technical field [0001] The invention relates to the field of pneumatic monorail crane equipment, in particular to a braking device for a pneumatic monorail crane and a use method thereof. Background technique [0002] Pneumatic monorail cranes are widely used in chemical, textile, painting, logistics, docks and other flammable, explosive, high-temperature, high-dust, corrosive workplaces in foreign industrialized countries. Because of its high frequency and infinitely variable speed characteristics , is favored by the automobile, tractor, motor, refrigerator and other manufacturing industries with large output and strong continuous operation, as well as the logistics industry, especially in some industrially developed countries. In some cases, the use of pneumatic monorail cranes must be mandatory. [0003] During the use of the existing pneumatic monorail crane, it is necessary to adjust the height of the lifted object. At this time, it is necessary to ensure that the obje...

Problems solved by technology

[0004] The object of the present invention is to provide a brake device for a pneumatic monorail crane and its use method. In order to overcome the above-mentioned existing pneumatic monorail crane during use, it is necessary to adjust the height of the lifted object. At this time, it is necessary to ensure that the object is in Keep fixed at high altitude; at the same time, during the lifting process of the sling of the pneumatic monorail crane, especially when it is used in outdoor places, external environmental factors will affect the stability of the sling when it is lifted, which will cause the sling to be lifted during the lifting process. Shaking conditions will seriously affect the lifting and transportation of objects, and at the same time pose a safety hazard; while lifting and lowering the sling, it is always necessary to ensure that the sling is in a vertical state, otherwise it will easily cause technical problems of tilting the lifting object during the lifting process
