The invention relates to a device for quick loading, unloading and lifting for a suspension movable support. The device for quick loading, unloading and lifting for the suspension movable support comprises a mining flat car. The front end and the rear end of the mining flat car are provided with a pathway holder respectively. A stand column is arranged on the mining flat car. The lower portion and the upper portion of the front side of the stand column are provided with a first double ear base and a second double ear base respectively. A U-shaped groove which is transparent in the front and back is formed in the upper end of the stand column. The upper end of the stand column is hinged to an adjusting cylinder which is located in the U-shaped groove, and the front end of the adjusting cylinder stretches out of the U-shaped groove. The first double ear base is hinged to a lifting cylinder. A plane four bar mechanism is arranged between the adjusting cylinder, and the lifting cylinder and the second double ear base. A bracket is arranged at the front end of the plane four bar mechanism. The hydraulic drive is utilized in the device for quick loading, unloading and lifting for the suspension movable support, the suspension movable support is lifted by machinery, the action is sensitive and reliable, the unloading efficiency is improved greatly, the labor intensity of workers is reduced, and personnel for loading and unloading is reduced.
Description
technical field [0001] The invention belongs to the technical field of coal mine safety production, and in particular relates to a fast loading and unloading lifting device for a suspension bracket. Background technique [0002] The suspension support is a type of support between the single hydraulic prop and the self-moving hydraulic support, and is mainly used for the support of the coal mining face of small and medium-sized coal mines. Due to the geological conditions and boundary restrictions of small and medium-sized coal mines, the layout of the working face is mostly irregular, resulting in the frequent removal and installation of suspension supports. At present, the installation of a suspension bracket requires the cooperation of 8 people. It is completed manually with the help of chain hoists. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a lifting device for quick installation and disassemb...
