High-safety double-beam bridge crane

Abstract

The invention discloses a high-safety double-beam bridge crane, and relates to the technical field of double-beam cranes. A high-safety double-beam bridge crane comprises a double-beam lifting support, a fixing plate is arranged on the left side of the double-beam lifting support, a sliding groove is formed in the inner side of the double-beam lifting support, and the inner wall of the sliding groove in the double-beam lifting support is connected with a crane in a sliding mode. According to the high-safety double-beam bridge crane, after collection in the collection box is completed, the collection box can be quickly disassembled for cleaning through sliding of the collection box and the built-in groove, and impurities cleaned on the inner wall of the limiting groove can be conveniently and intensively collected and cleaned through a triangular pyramid-shaped cleaning plate; the safety of use between the double-beam lifting support and the crane is guaranteed, the defect that a driving mechanism in the crane is damaged due to the fact that impurities on the inner wall of the limiting groove cause resistance to the pulley is overcome, and the service life and good protection performance between the crane and the double-beam lifting support are guaranteed.

Description

technical field [0001] The invention relates to the technical field of double-girder cranes, in particular to a high-safety double-girder bridge crane. Background technique [0002] There are three types of operating rooms for double-girder bridge cranes: separate type, closed type, and heat preservation. There are two types of cranes, indoor and outdoor. When ordering, the technical requirements such as the highest and lowest temperature of the working environment and the type of power supply should be indicated. An overload limiter, a large-screen display and various protection devices have been added to further increase the safety during use. For a MZ type double-girder bridge crane for outdoor use, although the efficiency of the double-girder bridge crane is relatively high during work, due to the relatively strong outdoor wind, when the wind blows the dust and impurities in the air to Inside the support frame of the double-girder bridge crane, a certain amount of dust ...

Problems solved by technology

[0002] There are three types of operating rooms for double-girder bridge cranes: separate type, closed type, and heat preservation. There are two types of cranes, indoor and outdoor. When ordering, the technical requirements such as the highest and lowest temperature of the working environment and the type of power supply should be indicated. An overload limiter, a large-screen display and various protection devices have been added to further increase the safety during use. For a MZ type double-girder bridge crane for outdoor use, although the efficiency of the double-girder bridge crane is relatively high during work, due to the relatively strong outdoor wind, when the wind blows the dust and impurities in the air to Inside the support frame of the double-girder bridge crane, a certain amount of dust and impurities will fall between the crane and the double-girder bridge arm. In turn, it will cause a certain obstacle to the sliding between the crane and the double-girder bridge arm, and will also increase the frictional resistance between the crane and the double-girder bridge arm, which will cause damage to the driving mechanism inside the crane and will also pass through the crane. The friction between the double-girder bridge arm causes damage to the surface body of each other, etc.
