This application discloses a group-opening sludge filter press, relating to the field of sludge and wastewater treatment. It includes a frame and a filter press assembly mounted on the frame. The frame includes side beams, and along the side beams from one end to the other, an end frame, a movable frame, an extrusion end plate, and another end frame are sequentially arranged. The filter press assembly includes several filter press components disposed between the extrusion end plate and the end frame at the other end. A central push plate, dividing the filter press components, is disposed between the extrusion end plate and the end frame at the other end. The extrusion end plate and the end frame at the other end are connected by a connecting chain, and the central push plate and the filter press components are all connected to the connecting chain. A power mechanism A drives the extrusion end plate to slide along the length of the side beams. A power mechanism B drives the movable frame and the central push plate to move along the length of the side beams. This design solves the problems of existing filter presses, achieves group-opening and closing of the plates twice, reduces equipment length and floor space, and improves production efficiency.

This application provides an automated pneumatic drilling machine, including a frame with a base platform mounted on it; a first transverse platform for providing movement in a first horizontal direction; a second transverse platform for providing movement in a second horizontal direction, with the first and second horizontal directions perpendicular to each other; and a pneumatic drilling assembly including a cylinder and a pneumatic drill bit, the pneumatic drilling assembly moving perpendicular to the base platform and used to drill a workpiece placed on the second transverse platform. The start and stop of the first and second transverse platforms and the pneumatic drilling assembly are all controlled by a PLC control module. This application features overload protection and impact resistance. The pneumatic system itself is compressible; when the drill bit encounters a hard point and gets stuck, the pneumatic cylinder or the pneumatic drill bit can instantly absorb the impact energy through internal pressure relief or "slippage," avoiding rigid damage to the transmission mechanism. The equipment is safer, has a longer service life, and the pneumatic system has a simple structure and low maintenance cost.

This invention belongs to the field of pipeline installation technology and discloses an auxiliary device for pipeline installation in underground tunnels. The device includes a frame with two support plates on its top. A support plate slides vertically along one side of the support plate. Through the cooperation of interception and locking components, the locking plate, utilizing the resilience of a spring-loaded telescopic rod, ensures its inner wall continuously adheres to the outer surface of the roller, preventing the operator from pushing the pipeline. Even when the roller is movable, the raised interception plate further prevents pipeline movement. By adjusting the pipeline height to align it with the pipeline inside the tunnel, rotating the handle allows the roller to move. During the movement of the locking plate, the corrugated pipe is compressed, causing the air inside to push the pressure plate, thus fixing the position of the pipeline at the top of the device with the pipeline inside the tunnel, thereby improving the accuracy of the connection work.
