Abstract

The invention discloses a roadway work surface hydraulic roof connecting device, which comprises an outer square box, wherein the outer square box is connected onto a base of the roof connecting device through a hinge, a support frame is fixed under the base of the roof connecting device, the support frame is in contact with the ground during the work, a slideway is arranged in the outer square box, a movable square box is arranged on the slideway, a roof connecting jack is arranged in the outer square box, the top of a piston rod of the roof connecting jack is connected with the movable square box through a shaft, the upper part of the movable square box is provided with a sleeve, a roof connecting rod is arranged in the sleeve, and the roof connecting rod is connected with a roof connecting plate through a spherical surface. The roadway work surface hydraulic roof connecting device has the advantages that (1) the hydraulic driving is adopted, and the heavy physical work of personnel is reduced; (2) the mechanical operation is realized, and the work efficiency is high; (3) the adaptability is high, the application is wide, and the device can be mounted on any equipment with roof connecting requirements; and (4) the roof connecting rod and the roof connecting plate are connected through the spherical surface, the local unevenness and inclination of a roof plate can be met, the contact area of the roof connecting plate and the roof plate is large, and the roof connecting stability is good.

Description

technical field [0001] The invention relates to the field of mining machinery and equipment, in particular to a hydraulic jacking device for a working face in a shaft. Background technique [0002] When temporarily fixing a piece of equipment in the underground working face, the method of top connection is often adopted. The traditional roof connection method is: use a log to stand in the roadway, put a square log under the log and the top of the log, and use wooden wedges between the log below and the square log to fix the log, and then Then tie the equipment that needs to be fixed to the log. This method not only wastes a large amount of manpower and material resources, but also has poor jacking effect and poor stability, and is prone to safety accidents when the jacking device loses stability. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a mechanical roofing device, which not only ...
