Abstract

The invention discloses a temporary supporting device of a driving machine. The temporary supporting device of the driving machine is composed of a large arm, a lifting jack, a cross beam, a longitudinal beam and a longitudinal beam jack, the lower end of the large arm is connected with a driving machine body, the upper end of the large arm is connected with the cross arm, one end of the lifting jack is connected with the large arm, the other end of the lifting jack is connected with the driving machine body, at least one longitudinal beam is arranged on the cross beam, a plurality of idler wheels are arranged on the longitudinal beam, and the longitudinal beam jack is connected between the cross beam and the longitudinal beam. The temporary supporting device can conduct continuous temporary supporting on a top plate in the coal cutting process of the driving machine, the driving machine can move without lifting the temporary supporting device, permanent supporting work is carried out behind the driving machine, driving and anchoring parallel work is achieved, and the driving efficiency is greatly improved.

Description

technical field [0001] The invention relates to a supporting device for roadway excavating machinery. technical background [0002] Most of the temporary support devices of tunneling machinery are installed in the cutting section at present, and they are lowered and retracted when cutting coal and moving, and are supported again when bolting. The main problems are as follows: 1. The roof cannot be continuously supported with the movement of the excavation machinery; 2. The parallel operation of coal cutting and permanent support cannot be realized by the excavation machinery; The destructive effect is obvious. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the temporary support device of the excavating machinery at present, and to provide a temporary support device capable of continuous support. [0004] The temporary support device for tunneling machinery of the present invention is composed of a boom, a lift...
