Lifting device applied to paving of monorail crane for coal road heading machine

Abstract

The invention discloses a lifting device applied to the paving of a monorail crane for a coal road heading machine. The lifting device comprises a bracket, a sprocket wheel, a lifting rail, a supporting frame, a lifting oil cylinder, a walking oil cylinder, a pedestal, a walking rail, a chain and a combination bearing, wherein the whole lifting device is located on a rear matching trailer C of the heading machine in a road B; two sides of the bracket are in contact with an inner-side vertical rail of the lifting rail by utilizing the combination bearing; an outer-side vertical rail of the lifting rail is connected with the combination bearing on the supporting frame; the supporting frame is in contact with an internal plane rail of the walking rail thorough the combination bearing mounted at a bottom; afterwards, the walking rail is connected with an internal plane rail of the pedestal through the combination bearing; and the lifting oil cylinder is mounted, in the vertical direction, on the supporting frame, and moves round the sprocket wheel by using the chain to be connected with the bracket and the supporting frame. By using the lifting device applied to the paving of the monorail crane for the coal road heading machine, the rail speed of the monorail carne is quick in a lifting process; the level of the modernization of equipment is high; the adjustment and the assembly are easy; the heavy manual labor does not exist; the mounting efficiency of paving a rail of the monorail crane is improved; and the lifting device is applied to the technical field of open type coal-mine coal road heading machines.

Description

technical field [0001] The invention relates to a hoisting device applied to the laying monorail crane of the coal roadheading machine, which is specifically limited to the environment of laying monorail cranes in the technical field of open coal mine rock roadheading machines. Background technique [0002] At present, in the working environment of coal mine and rock roadway, the monorail crane is an important transportation system that is connected by hanging vehicles with various functions to form a car group, which is pulled by traction equipment and runs along the track. The monorail crane uses a special I-beam hanging above the roadway as the track. In the past, the installation of this I-beam track required manual connection and installation of the track by using a hand chain hoist to hang on the anchor above the roadway. The efficiency of lifting the monorail crane track to the specified height by hand or electric hoist is not high, and it is difficult to adjust the c...
