Abstract

The invention provides a support beam, forepoling equipment and a support beam circulating laying method, and relates to the technical field of roadway forepoling. The support beam is applied to roadway forepoling and comprises a first beam body, a second beam body and a third beam body, the two ends of the second beam body are correspondingly hinged to one end of the first beam body and one end of the third beam body through a set of hinge pieces, and the first beam body and the third beam body can rotate towards the same side of the second beam body; and reset parts are arranged at the hinged position of the first beam body and the second beam body and the hinged position of the second beam body and the third beam body correspondingly, and the reset parts are used for driving the first beam body, the second beam body and the third beam body to rotate to the collinear position. The forepoling equipment comprises a forepoling device and the support beam. According to the support beam circulating laying method, the forepoling equipment is adopted for performing circulating laying on the support beam. When the support beam is applied to forepoling equipment, the forepoling device is simple in structure and small in occupied space, and the support beam is conveniently and rapidly laid in a circulating mode.

Description

technical field [0001] The invention relates to the technical field of roadway advance support, in particular to a support beam, advance support equipment and a circular laying method for the support beam. Background technique [0002] In coal mine roadway excavation or mining operations, it is very important to carry out advanced support for the roadway. Among them, the advance support of the roadway has been widely used by using the advance support device and supporting steel beams in combination with circular laying. However, the existing advance support In order to achieve the circular laying of the supporting steel beams, the device has a complex structure, high requirements on the roadway space, and cumbersome laying operations. Contents of the invention [0003] The object of the present invention includes providing a kind of support beam, advance support equipment and support beam circular laying method, to solve the existing advance support device in order to real...
