A lifting material loading equipment

Abstract

The present invention discloses a lifting material loading device, comprising: a material discharge outer cylinder, a material discharge inner cylinder, a lifting assembly, a loading assembly, a dust removal assembly, a filter element, a material level meter, an outer flexible structure, an inner flexible structure, and a lower flexible structure. When loading materials, when the loading assembly descends to the mobile storage equipment, a drop-to-position switch is triggered, and the materials enter the mobile storage equipment through the material discharge inner cylinder, the flexible structure, and the loading assembly. When the materials in the mobile storage equipment trigger the material level meter in the loading assembly, the lifting motor is started, and the external steel wire rope drives the loading assembly to rise through a flexible connection, triggering the rise-to-position switch and stopping the lifting motor. The dust removal fan sucks out the dust filtered by the filter element. In order to prevent the filter element from being blocked, a blowing device is used to back-blow the filter element to ensure the filtering capacity of the filter element. The present invention avoids direct contact between the external lifting steel wire rope and the material and fatigue, bending, and fracture of the material level meter connecting cable, thereby improving the reliability of the equipment operation and having a high degree of automation.

Description

Technical Field

[0001] The invention belongs to the technical field of material loading and relates to a lifting material loading device. Background Art

[0002] Modern industrial development has put forward high reliability and high efficiency requirements for material loading equipment. The wire rope in the lifting assembly of the lifting material loading equipment in the prior art is in direct contact with the material, which is easily eroded and corroded by the material. In addition, due to space limitations inside the loading equipment, the wire rope cannot reach an effective bending radius, so the wire rope is prone to fatigue fracture and has a short service life. The fracture of the wire rope is easy to contaminate the material, and the shutdown of the lifting material loading equipment seriously affects the operation and production efficiency of the production line.

[0003] In the prior art, the wire rope of the lifting material loading equipment is inside the equipment, and the wire rope lifting mechanism is outside the equipment. Therefore, the wire rope has to pass through the equipment, which has the problem of sealing leakage. After running for a period of time, dust leakage is prone to occur due to wear and tear, affecting the on-site environment. Summary of the invention

[0004] The technical problem solved by the present invention is: to overcome the shortcomings of the prior art and to propose a lifting material loading equipment, in which the external steel wire rope does not directly contact the material, is not restricted by space, the bending radius can be reasonably designed, and there is no dust leakage problem, so that the equipment has higher reliability and high production efficiency.
