The invention discloses a hydraulic pipe cutting machine for horizontally frozen pipes in a tunnel, which includes a frame. Guide rods are fixedly connected to both sides of the top of the frame. The surface of the guide rod is slidably connected to a sliding sleeve. A drive mechanism is fixedly connected; a knife feed mechanism is fixedly connected in the middle of the top of the frame, and the end of the movable rod of the knife feed mechanism is fixedly connected with the drive mechanism; the bottom of the drive mechanism is connected with a mechanical inner knife mechanism. In the present invention, by setting the driving mechanism, the power of the driving mechanism is a hydraulic motor, the hydraulic motor is small in size, light in weight, impact-resistant, and the power output is relatively stable, which can provide a stable power source for the mechanical internal cutter mechanism, and the hydraulic motor only needs to cooperate Generally, the hydraulic pump station can be used, which is convenient for construction and movement in tunnels with small spaces, and the hydraulic pump station and the pipe cutter adopt a split structure. When operating, the hydraulic pump station is placed at the bottom of the tunnel, and only the cutting pipe needs to be moved. The machine can carry out pipe cutting machine operation.

The invention relates to a no-cut scaffold fastener bolt maintaining machine. The no-cut scaffold fastener bolt maintaining machine comprises a tray bracket, a motor fixed in the tray bracket, and an intermediate shaft driven by the motor and supported on the tray bracket, wherein one end of the intermediate shaft is fixed with one end of a fast T-shaped spanner; a first groove is formed in the other end of the fast T-shaped spanner, and is matched with a no-cut scaffold fastener bolt cap in shape; the no-cut scaffold fastener bolt maintaining machine further comprises a nut spanner component arranged on the tray bracket and capable of sliding and rotating along the tray bracket; the nut spanner component comprises an end provided with a second groove; the second groove is matched with a no-cut scaffold fastener bolt in shape; and when an end provided with a second groove nut spanner component is rotated to a horizontal position, the axis of the second groove is overlapped with the axis of the first groove. The no-cut scaffold fastener bolt maintaining machine can realize automatic feeding, is high in working efficiency, omits the cutter cutting step because of the bolt rust, has the benefits of economy, practicability, safety and reliability, and is an efficient tool for fastener bolt maintenance.

The invention discloses an appliance switch forming device. The appliance switch forming device comprises a forming table. Supporting plates are fixed to the two sides of the top of the forming table.Sliding rails are fixed to the opposite side faces of the two supporting plates. A top plate is fixed to the top of the two supporting plates. First push rod motors are fixed to the two sides of thetop of the top plate. A second push rod motor is mounted in the middle of a mounting plate. A push rod is fixed to the lower end of the second push rod motor. A sliding plate is fixed to the lower endof the push rod. Sliding blocks are arranged on the two sides of the sliding plate and slidably connected to the sliding rails. The sliding plate slides up and down on the sliding rails. An upper pressing plate is fixed to the bottom of the sliding plate through bolts. A mounting groove is formed in the top of the forming table. Storage grooves are formed in the two sides of the bottom of the mounting groove. Third push rod motors are mounted in the storage grooves. A lower pressing plate is mounted at the bottom of the mounting groove. The appliance switch forming device is reasonable in structure, unique in design, novel in structure and suitable for popularization.

The invention relates to a heading machine memory cutting control system and a method of the heading machine memory cutting control system. The heading machine memory cutting control system is composed of a detection unit, a control unit, a proportion amplification plate, a load sensitivity type proportion reversal valve group and an execution unit, wherein the control unit comprises a PCC (programmable computer controller), an intelligent operation control panel, a remote controller and a machine body operating handle; and heading machine memory cutting comprises a manual demonstration process and a memory automatic cutting process. The method comprises the following steps that: firstly, a heading machine driver utilizes the remote controller or the machine body operating handle to operate the heading machine to cut once according to a top plate and a bottom plate of a coal seam and the coal rock distribution condition, and an airborne computer control system records information a demonstration path detected by the detection unit; and then the recorded keypoint data is subjected to path matching and intelligent optimization, a control signal is sent to the execution unit according to the path after optimizing, so that a cutting head is automatically controlled to move along a demonstration track, and the memory automatic cutting is performed. The heading machine memory cutting control system is also provided with a boundary control function in the whole memory cutting process, and the tunnel shaping quality when the manual cutting and memory automatic cutting are performed is ensured. The heading machine memory cutting control system and the method of the heading machine memory cutting control system provide a new control means for heading of a coal road boom-type roadheader under the condition with stable surrounding rock of roadway.
