Abstract

The invention provides a hydraulic supporting mechanism for underground obstacles. A mounting box is fixed at the upper end of a base; a bracket is detachably fixed in the mounting box; a jack is detachably fixed on the bracket; one side wall of the mounting box is provided with an operation hole for being inserted into a jack rod; and a supporting plate is fixed at the upper end of the jack. Thehydraulic supporting mechanism has the advantages that the structure is simple, the jack is convenient to operate, the jack has stability to a certain extent, and the supporting plates of different shapes can be selected according to different shapes of the obstacles.

Description

technical field [0001] The invention belongs to the field of supporting devices, in particular to a hydraulic supporting mechanism for underground obstacles. Background technique [0002] The jack is the simplest lifting equipment with a lifting height of less than 1m. It uses a rigid top lifting piece as a working device, and is a light and small lifting equipment that lifts heavy objects in the stroke through the top bracket or bottom claw. There are two types of mechanical and hydraulic. When working underground, there will be a vertical obstacle at a certain point in the vertical height, and a jack is needed to support the obstacle. However, due to the unevenness of the underground ground, it is difficult for the jack to be used stably and normally. Contents of the invention [0003] In view of this, the present invention aims to propose a hydraulic jacking mechanism for underground obstacles, which can solve the above-mentioned technical problems. [0004] In order...
