Abstract

The present invention relates to a kind of mining equipment, in particular to a hydraulic support truck, which includes a driving device and a bearing device, and the driving device includes an articulated frame, a driver's cab, an engine, a hydraulic gearbox, a drive shaft, and a drive axle. , brakes and wheels. The articulated frame is composed of a front frame and a rear frame. The engine is connected to the drive shaft through a gearbox. The drive shaft is set under the front and rear frames. Connected to the wheels through the front drive axle. The carrying device includes a "U"-shaped frame, a lifting device, a supporting cylinder and a hydraulic control system. A trapezoidal bracket is arranged at the front of the "U"-shaped frame, and the trapezoidal bracket is hingedly connected with the rear of the rear frame. There is a lifting device above the "shaped frame, and the lifting device is connected to the upper part of the "U" frame through a swing hydraulic cylinder, and a supporting cylinder is provided under the front of the "U" frame. The invention has the characteristics of simple structure, low center of gravity, stable operation, convenient and quick loading and unloading, flexible and fast transfer.

Description

Technical field [0001] The utility model of the invention relates to a mining equipment, specifically a hydraulic support truck. Background technique [0002] Hydraulic support is an important part of comprehensive mining equipment. It can reliably and effectively support and control the roof of the working face, isolate the goaf, prevent gangue from entering the working face and push the conveyor. It is used in conjunction with the shearer and is an indispensable supporting equipment for comprehensive mechanized coal mining. At present, the transportation of hydraulic supports used in coal mines is mainly carried by rail winches. Rail winches involve tracks, walking mechanisms, power hoists and control mechanisms. The structure is complex, the cost is high, and the operation is cumbersome. The center of gravity of the hydraulic supports is high during the transportation process. Unstable operation, slow rotation speed and poor safety performance. Summary of the invention [00...
