Temporary roof support system

Abstract

A temporary roof support system of a roof bolter machine is provided. The temporary roof support system includes a multistage cover assembly, a sliding assembly, a guiding assembly and a first actuator. The sliding assembly is coupled to the multistage cover assembly. The guiding assembly is coupled to a boom of the roof bolter machine, and is configured to guide the sliding assembly in a predetermined direction. A first end of the first actuator is coupled to the guiding assembly by a first pivot joint, and a second end of the first actuator is coupled to the multistage cover assembly by a second pivot joint. An extension of the first actuator along the length translates the multistage cover assembly in the predetermined direction, by guiding of the sliding assembly by the guiding assembly in the predetermined direction.

What is claimed is: 
     
         1 . A temporary roof support system of a roof bolter machine, comprising:
 a multistage cover assembly;   a sliding assembly coupled to the multistage cover assembly;   a guiding assembly coupled to a boom of the roof bolter machine, the guiding assembly configured to guide the sliding assembly in a predetermined direction; and   a first actuator extendable along a length of the first actuator, the first actuator having, a first end and a second end, the first end of the first actuator coupled to the guiding assembly by a first pivot joint, and the second end of the first actuator coupled to the multistage cover assembly by a second pivot joint;   
       wherein an extension of the first actuator along the length translates the multistage cover assembly in the predetermined direction, by guiding of the guiding assembly by the sliding assembly in the predetermined direction.
