Abstract

The invention relates to the technical field of hydraulic supports, and discloses a hydraulic double-telescopic support convenient to mount. The hydraulic double-telescopic support convenient to mountcomprises a mounting fixing base. According to the hydraulic double-telescopic support convenient to mount, by arrangement of a threaded adjusting rod and a threaded fastening barrel which is in threaded connection with the outside of the threaded adjusting rod, a draw rod can rotate in a connecting shaft which is fixedly mounted on the threaded fastening barrel by rotating the threaded fasteningbarrel, thus, moving struts which are fixedly mounted on two hydraulic telescopic support bodies move in a hollow barrel, the distance between the two hydraulic telescopic support bodies is adjusted,separate distance-adjusting installation on the two hydraulic telescopic supports is avoided, the two hydraulic telescopic support bodies can be fixedly mounted by fixing a threaded fixing rod, meanwhile, distance-adjusting installation on the two hydraulic telescopic support bodies can be finished by rotating the threaded fastening barrel, and the purpose of conveniently mounting the hydraulic double-telescopic support is achieved.

Description

technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to an easy-to-install hydraulic double telescopic support. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. The mine pressure of the mining face acts on the hydraulic support in the form of external load. The resultant force of the support and the resultant force of the external load acting on the hydraulic support by the roof are exactly on the same line, so the hydraulic support is very suitable for the surrounding rock of this mining face. [0003] With the development of the times and science and technology, the progress of science and technology has also promoted the technical progress of the double telescopic support for hydraulic pressure, but there are still defects. The current double telescopic support for hydraulic pressure often adopts a single installation, which is extremely complic...
