Abstract

The invention discloses a double row type fore support. The double row type fore support comprises two rows of support bodies distributed in a left and right mode, a transverse reinforcing device is connected between the two rows of support bodies, and the two rows of support bodies each comprise a base, a top beam and a lifting driving device. The upper and lower ends of the lifting driving devices are separately connected with the bases and the top beams, the left and right sides of the top beams can be adjusted in a vertical rotation mode, and the lifting driving devices of the support bodies on both sides can independently perform lifting driving. According to the double row type fore support, the support bodies are separately arranged on the left and right sides, the top beams of theleft and right support bodies can be independently adjusted in height, and then the top beams are adapted to a left-and-right-inclined roadway roof; and in addition, the left and right sides of the top beams can be adjusted in a vertical rotation mode, the upper side surfaces of the top beams can incline adapting to inclination of the roadway roof, surface contact is ensured, and therefore stablesupporting is effectively ensured. In summary, the double row type fore support can effectively solve the problem of poor adaptation effect of a current roadway roof support.

Description

technical field [0001] The invention relates to the technical field of roadway support, and more specifically, relates to a double-row advance support. Background technique [0002] The advanced support is applied to the roadway support of the roof, that is, to support the roof of the roadway. The current advance support is only suitable for rectangular roadways, and the inclination angle of the roof of the roadway is nearly horizontal. If the roof of the roadway has a certain inclination angle, the current top beam of the advanced support can only support the roof on one side, and workers need to use skids to place the other end of the roof beam, so that the current advanced support can support the roof with a certain inclination angle. . [0003] However, due to the high roadway of the working face, workers are prone to danger during the process of placing skids, resulting in accidents. At the same time, due to the uneven support of the top beam, it will lead to the ben...
