The technical scheme in this application embodiment is for solving the self-moving formula rubber belt conveyor tail that mentions among the above-mentioned background art when running into transportation crossheading tunnel bottom plate unevenness, takes place the problem that the tail bored the ground in the propulsion process, and the general thinking is as follows:
referring to fig. 1, the bottom adjusting cylinder device of the tail of the belt conveyor comprises a tail 100 of the belt conveyor and a bottom adjusting assembly 200.
The bottom adjusting assembly 200 is provided with certain mobility to the rubber belt conveyor tail 100 by means of the matched extension and retraction of the longitudinal extension cylinder 220 and the transverse extension cylinder 230, the rubber belt conveyor tail 100 can be prevented from drilling the ground when moving automatically, the pushing capacity is provided, the rubber belt conveyor tail is helped to be separated from a ground sinking area, and the whole self-moving rubber belt conveyor has better reliability.
Referring to fig. 1-4, the bottom adjustment assembly 200 includes a mounting frame 210, a longitudinal telescopic cylinder 220, a transverse telescopic cylinder 230, and a base 240, the mounting frame 210 is fixedly connected to the tail 100 of the belt conveyor, the longitudinal telescopic cylinder 220 and the transverse telescopic cylinder 230 are both hinged to the mounting frame 210, and the telescopic ends of the longitudinal telescopic cylinder 220 and the transverse telescopic cylinder 230 are both hinged to the base 240. Here, the longitudinal telescopic cylinder 220 and the transverse telescopic cylinder 230 cooperate to perform downward ejection and backward ejection of the base 240, when the tail 100 of the rubber belt conveyor works normally, the base 240 ejects downward to eject the sunken tail to prevent the tail from moving, so as to reduce the load of rails on two sides of the rubber belt conveyor and reduce the sinking of the rails, when the tail 100 of the rubber belt conveyor needs to move automatically, the base 240 is retracted and attached to the mounting frame 210, so that the whole bottom adjusting assembly 200 is retracted at the lower part of the tail 100 of the rubber belt conveyor, at this time, the rails on two sides of the rubber belt conveyor perform all supporting functions, the whole conveyor moves forward under the driving of the self-pushing cylinder, if the rails cannot perform the supporting functions due to ground sinking, the base 240 ejects downward backward, the tail and the rails move forward and upward, after the whole rubber belt conveyor is separated from the sunken area, the tail recovers to perform normal actions, so that the tail 100 of the rubber belt conveyor is provided with certain flexibility by the cooperation of the longitudinal telescopic cylinder 220 and the transverse telescopic cylinder 230, and the tail 100 of the rubber belt conveyor can be prevented from moving reliably in the whole tail conveyor.
