Abstract

The invention discloses a two-degree-of-freedom sliding-type temporary supporting device and a working method thereof. The two-degree-of-freedom sliding-type temporary supporting device comprises a first supporting device, a second supporting device, a frame moving driving device and a frame moving auxiliary device. The first supporting device and the second supporting device are connected throughthe frame moving driving device and the frame moving auxiliary device. Under the joint effect of a bottom lifting device arranged at the bottom of the first supporting device and facilitating slidingand forward moving, the frame moving driving device and the frame moving auxiliary device, the sliding-type temporary supporting device automatically slides and moves forwards to the designated working position. The first supporting device and the second supporting device adopt two sets of structures which are connected and combined by three linear driving devices and hinges, so that a jacking support has two degrees of freedom. The problem that when the ground and the top face of a roadway are not parallel, the device is prone to overall skewing is solved, meanwhile, auxiliary equipment is not needed during frame moving, the pushing step pitch is large, supporting is safer and more reliable, and the two-degree-of-freedom sliding-type temporary supporting device and the working method thereof have the advantages that the work efficiency is high, the automation degree is high, and adaptability to the top face of the roadway is good.

Description

technical field [0001] The invention relates to a sliding type temporary support device, in particular to a two-degree-of-freedom sliding type temporary support device and a working method thereof, belonging to the technical field of underground mining machinery and equipment. Background technique [0002] With the improvement of the degree of mechanization of coal mining, in order to meet the installation requirements of large-scale fully mechanized mining equipment, the width of cutting holes in many fully mechanized mining faces is designed to be 8m to 10m. For super-large-span cut-out construction, the main form of support for the cut-out in the fully mechanized mining face is shed support. The construction space of the roadway with shed support is small, which makes it difficult to install and construct the support. At the same time, the shed support is a passive support and cannot Effectively improve the bearing strength of surrounding rock finishing, the support metho...
