Framework landing self-moving type front telescopic advanced supporting device

Abstract

A framework landing self-moving type front telescopic advanced supporting device comprises a lifting structure and a supporting structure fixed on the lifting structure. The framework landing self-moving type front telescopic advanced supporting device is characterized in that the lifting structure comprises lifting bases; lifting middle beams are arranged on the lifting bases; firming devices and lifting oil cylinders are arranged between the lifting bases and the lifting middle beams; arched upper beams are mounted on the lifting middle beams; the supporting structure is arranged on the arched upper beams; the supporting structure comprises track pipes fixedly connected with the arched upper beams; and telescopic arms are arranged on the track pipes. Self-moving devices are arranged in the lifting bases, the self-moving devices comprise moving oil cylinders, the upper ends of the moving oil cylinders are connected with the lifting bases, base plates are arranged at the lower ends of the moving oil cylinders, vertical plates and side skewed tooth plates are arranged on the periphery of each base plate upwards, skewed teeth are arranged under the base plates, and after the moving oil cylinders stretch out, thrust is formed with the ground to finish self-moving of the lifting bases.

Description

technical field [0001] The invention relates to an advance support, in particular to a frame landing self-moving front telescopic advance support device. Background technique [0002] The current support method used in the coal mine excavation working face is to put on the lifting ring, put on the front probe beam, lay a net on the front probe beam (cover the unsupported roof), and then use wooden brakes, long and short back boards or road blocks to move the front probe The beam metal mesh is fixed, and the operation is carried out under the cover of the support. After the support is completed, it is unloaded and continued to move. The currently used advanced support is cumbersome to install, with high potential safety hazards and high labor intensity for workers. The existing advanced support has just become the main factor restricting and affecting the progress of the underground driving face. Contents of the invention [0003] The object of the present invention is to ...
