Description

Underground engineering drill jumbo that full period of time prevented collapsing Technical Field The invention relates to the technical field of mine tunnel construction, in particular to an underground engineering rock drilling trolley capable of preventing collapse in a full period of time. Background In underground engineering rock drilling construction, the rock mass of a mine roof is easy to loosen and collapse under the superposition influence of geological stress and tunneling vibration. Therefore, providing continuous and stable support to the mine roof during the entire process of operation and movement of the apparatus is a central resort to ensuring construction safety. However, the conventional rock drilling device mostly adopts a rubber disc as a supporting piece, and when the equipment moves or changes stations, all supporting pieces are required to be separated from the inner wall of a mine channel, so that an unsupported 'empty window period' is inevitably formed at the top of the mine channel, and obvious potential safety hazards exist. The prior art has related improvement attempts to this, for example chinese patent CN118391044B discloses a collapse-preventing rock drilling device for underground engineering, which comprises a vehicle body, the vehicle body is provided with a driving steering function, the top surface of the vehicle body is provided with two first turntables, the vehicle body is provided with an adjusting device for driving the two first turntables to synchronously and reversely rotate, the eccentric position of the first turntables is respectively rotated and installed with two first hydraulic rods, the corresponding first hydraulic rods on the left and right sides are respectively provided with a top plate, the two sides of the bottom surface of the top plate are respectively provided with a sliding groove, and sliding strips are respectively arranged in the sliding grooves. However, according to the analysis prior art, the device is used for alternately supporting the inner wall of the mine channel in order to prevent collapse of the mine channel during rock drilling, and the device is used for contracting and separating the top plate positioned at the rear side from the inner wall of the mine channel during forward movement along with a vehicle body, and then crossing to the front side for supporting again through rotation of a turntable. During the displacement movement cycle of this position, although theoretically one top plate remains in contact at all times, the local support area is momentarily halved and the overall support stiffness of the system decreases. More importantly, a physical distance which cannot be effectively covered by the top plate is necessarily left between the new supporting position and the old supporting position in the process of alternately stepping the front top plate and the back top plate. This means that as the car body advances, the roof of the inner wall of the mine tunnel periodically becomes a supporting "dead zone" for a distance, in an unsupported suspended state. Because the geological condition of the surrounding rock of the underground engineering is complex and the stress change of the rock stratum is extremely rapid, the discontinuous and partial void supporting mode cannot realize continuous and seamless protection of the top of the mine channel, the rock stratum is easily caused to loosen and fall off in the left unsupported area, and the potential safety hazard of larger collapse still exists. Disclosure of Invention The technical problem to be solved by the invention is to provide the underground engineering rock drilling trolley capable of preventing collapse in a full period of time, so that the top of the inner wall of a mine channel is always in a back support state in the moving process of the device, and the implementation safety of underground engineering is further ensured. To solve the above technical problems, an embodiment of the present invention provides an underground engineering drill jumbo for preventing collapse in a full period of time, including: A crawler machine chassis; the rock drill is fixed at the front end of the crawler machine chassis, and the drill bit faces to the front of the mine channel; The two support modules are symmetrically arranged at the front end and the rear end of the crawler mechanical chassis bearing table, each support module comprises a support assembly, a longitudinal driving assembly and a top plate, the top of the support assembly is fixedly connected with the bottom of the top plate, the longitudinal driving assembly is arranged on the support assembly and used for driving the support assembly to move up and down so as to enable the bottom of the support assembly to be in separable contact with the mine floor, the support assembly moves up and down so as to drive the top plate to be in separable contact with the top of the inner wall of the mine, and the top plate is f
