Supporting frame used for mining excavating equipment

Abstract

The invention discloses a supporting frame used for mining excavating equipment. The supporting frame comprises a base. A movable plate is arranged above the base. Two sliding grooves are symmetrically formed in the upper surface of the base. The bottom surface of the movable plate is fixedly connected with two sliding blocks which are arranged symmetrically, and the ends, away from the movable plate, of the sliding blocks are clamped into the corresponding sliding grooves. A through hole is formed in the front face of each sliding block. A groove is formed in the upper surface of the base. The bottom surface of the movable plate is fixedly connected with a movable block. A threaded pipe is fixedly embedded in the front face of the movable block. According to the supporting frame used forthe mining excavating equipment, by arranging supporting rods, a supporting platform can be made more stable and prevented from inclining in the rotating process, and the supporting frame is made moredurable; and by arranging a first bearing and a third bearing which are used cooperatively, the threaded rod can rotate more smoothly, clamping stagnation in the rotating process of the threaded rodis prevented, and the service life of the supporting frame is prolonged.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a support frame for mining excavation equipment. Background technique [0002] There are many ways to classify mining methods, each with its own basis. Generally, the ground pressure management method in the mining area is used as the basis during the mining process. The ground pressure management method in the mining area is essentially based on the physical and mechanical properties of ore and surrounding rock. The physical and mechanical properties of ore and surrounding rock are often the main factors that cause differences in applicable conditions, structural parameters, cutting arrangements, mining methods, and main technical and economic indicators of mining methods. [0003] At present, the mining excavation equipment on the market generally needs to be manually held and cannot be adjusted. However, manual hand-holding is labor-intensive and has a high risk factor. Therefo...
