Rotary accommodating platform for hydraulic support for fully mechanized mining for coal mine

Abstract

The invention relates to a rotary accommodating platform for a hydraulic support for fully mechanized mining for a coal mine. The rotary accommodating platform comprises an upper platform, a lower platform and a track, wherein the lower platform is connected with the upper platform through a rotary bearing; the rotary bearing is connected by a rotary guiding device in a driving manner; a sliding shoe device is mounted at the bottom of the lower platform; the sliding shoe device is arranged on the track in a sliding manner; a support push-pull device and a carriage rotary supporting device are respectively installed on the two opposite sides of the upper platform; the support push-pull device is fixedly connected with one side of the upper platform through a supporting base; the carriage rotary supporting device is connected with the upper platform through a connecting base; one side of the connecting base is hinged with the carriage rotary supporting device; and the other side of the connecting base is fixedly connected with the upper platform. According to the invention, the transportation of the hydraulic support is achieved through the platform, so as to change the technical mode of the prior art that a winch and a single prop are used cooperatively with manual work in the support with the help of experience and coordination; as a result, safety is ensured, the labor intensity is decreased, and the working efficiency is improved.

Description

Technical field [0001] The present invention involves a rotation device of a comprehensive coal mine comprehensive mining equipment. Specifically, it is a coal mine comprehensive mining hydraulic bracket reincarnation platform. Background technique [0002] Under the coal mine well, after the comprehensive mining work surface is collected, it is necessary to remove and move the hydraulic bracket, install it in the new comprehensive mining work surface, the hydraulic bracket has a base, the base is connected to the pillars with the top beam, the front end of the top beam is hinged with the hinge of the pillar, there is a hinge of the top end of the beam.In front of the pilot beam, there is a cover beam of the back -end hinge. The hydraulic bracket is large and the weight is large. The number of hydraulic brackets in the set set of comprehensive mining work surfaces is large. According to the size of the working surface, there are generally more than 100 frames on the hydraulic bra...

Problems solved by technology

At present, the placement of domestic hydraulic supports adopts the return column winch to pull the hydraulic pressure from the flatbed truck to the ground, and then uses the return column winch to cooperate with the manual use of the single column top hydraulic support to turn 90°, which is labor-intensive, low-efficiency, and safe. There are many hidden dangers. The fully mechanized coal mining process is an efficient coal mining process, but the installation and withdrawal of the hydraulic support has always been a labor-intensive and time-consuming difficult task.
