Abstract

The invention relates to a shed supporting device of a roadway, in particular to a shed supporting roadway adjustable shield type hydraulic forepole supporting device in order to solve the problems that according to most existing shed supporting roadway forepoles, the problem that spalling and roof falling are prone to occur at a head-on coal face can not be solved, and traditional forepoles are not firm in fixation and inconvenient to detach. The shed supporting roadway adjustable shield type hydraulic forepole supporting device comprises a rotary pressing device, a base, a screw rod pressing plate, two movable clamping plates, two fixed clamping plates and two fixing rods, wherein the two fixed clamping plates are fixed to the base; the two movable clamping plates are arranged corresponding to the two fixed clamping plates; when a forepole is in an installed state, the fixed clamping plates and the corresponding movable clamping plates form a set of clamping device which is clamped on two sides of I-shaped steel of an I-shaped steel shed; one end of the forepole is fixed through a pressing screw rod; the other end of the forepole is fixed to one end of a supporting side beam through a fixing pin; and the forepole and the supporting side beam can rotate relatively. The shed supporting roadway adjustable shield type hydraulic forepole supporting device is suitable for shed supporting of the roadway.

Description

technical field [0001] The invention relates to a rack support device for a roadway. Background technique [0002] During the excavation process of coal mine underground roadway, it is very dangerous to work with empty top, and the country also strictly prohibits open top operation. In order to prevent the falling of rocks (coal blocks), temporarily maintain the stability of the surrounding rock and ensure the safety of the working face, the front probe beam is usually used as a temporary support to ensure the safety of the operators, so that the construction can continue. At present, most roadway shed support devices are large-scale automatic support devices for fully mechanized mining. This type of support device is only suitable for large-scale fully mechanized mining operations, not for small excavation faces. Traditional manual erection The shed support device has the problems of huge workload, time-consuming and laborious work, and poor support effect. [0003] Moreo...
