Pipe rail crane

Abstract

The invention relates to novel hoisting equipment, in particular to an integrated hoisting structure combining pipe rails and ball wheel trolleys, namely a pipe rail crane. The pipe rail crane comprises the pipe rails, the ball wheel trolleys, limiting flanges, connecting structures and butt-joint flanges; the pipe rails are composed of a plurality of straight sections and bent sections of slottedpipelines, and the sections are connected and fixed through the butt-joint flanges; the pipe rails are fixed to the tops of buildings such as tunnels or factory buildings through the multiple connecting structures; the ball wheel trolleys are arranged in the pipe rails; and the limiting flanges are mounted at the outermost ends of the head section and the tail section of each pipe rail and used for limiting the strokes of the ball wheel trolleys. The pipe rail crane has the advantages of high safety, low cost and simple installation and operation, and can be widely applied to various small and medium-sized hoisting places, in particular to hoisting operations of various underground projects.

Description

technical field [0001] The invention relates to a new type of hoisting equipment, in particular to a pipe rail crane, an integrated hoisting structure combined with a pipe rail and a ball wheel trolley. Background technique [0002] Single-girder cranes are mostly suitable for loading, unloading, and shipping of goods in workshops, warehouses, stockyards, and underground engineering environments. The main components are walking mechanisms and lifting mechanisms. At present, the application is relatively mature, and the installation and use methods are relatively simple, but there are still the following disadvantages: First, the main girder of the beam crane is generally an I-beam, and there is a risk of derailment when the traveling mechanism is turning or pulling sideways; If the traveling mechanism is exposed to the external environment for a long time, there will be dust pollution, blockage, etc., which will eventually cause the traveling mechanism to freeze and derail. ...

At present, the application is relatively mature, and the installation and use methods are relatively simple, but there are still the following disadvantages: First, the main girder of the beam crane is generally an I-beam, and there is a risk of derailment when the traveling mechanism is turning or pulling sideways; If the traveling mechanism is exposed to the external environment for a long time, there will be dust pollution, blockage, etc., which will eventually cause the traveling mechanism to freeze and derail; third, when the length of the main beam is too long, multiple I-beam connections are required, and the alignment process is cumbersome
