The embodiment of the utility model discloses diaphragm cutting equipment which comprises a rack, a working platform is arranged on the rack, a transverse moving assembly is arranged on the working platform, a longitudinal moving assembly is arranged on a transverse sliding frame, a tool bit assembly is arranged on the longitudinal moving assembly, and the transverse moving assembly comprises a sliding assembly and a supporting driving assembly which are matched with each other. The supporting driving assembly comprises a transverse driving motor, the driving end of the transverse driving motor drives a synchronous wheel through a gear, the synchronous wheel is meshed with a synchronous belt transversely arranged on the working platform, and the sliding assembly comprises transverse sliding rails symmetrically arranged on the two sides of the working platform and sliding blocks matched with the transverse sliding rails. The transverse sliding frame is connected with the sliding block, the synchronous wheel drives a driven gear installed on the transverse sliding frame through a synchronous gear arranged outside the synchronous wheel, and the two supporting and driving assemblies are in linkage through a synchronous shaft.

The utility model discloses a two -way drive explosion -proof diesel engine trackless rubber -tyred vehicle, including the head, two opposite driving cabins are fixed on the head, the left side fixed mounting of head has the buffer protection mechanism, the central fixed of head tail part has the connecting arm, and the head tail part is provided with the hanging bucket, and the self -lock buckle is fixed in the middle part lower extreme of hanging bucket, and the connecting arm is hinged together with the self -lock buckle. The utility model discloses a careful setting buffer protection mechanism in the left side of head provides multiple protection mechanism for the vehicle when encountering rear -end collision, when the collision occurs, the buffer protection mechanism is the first to contact the collision object, greatly slows down the impact force of collision to the head, thereby effectively protects the head and the personnel and equipment safety in the driving cab, and the loss caused by the accident is reduced significantly.
