The application belongs to the field of track assembly and relates to a positioning mechanism for assembly, which is used for positioning a plurality of products arranged in a straight line. The positioning mechanism comprises a bottom base plate, a locking piece and a correcting piece. The bottom base plate has a front surface and a back surface. The back surface is configured to be connected with the ground in a positioning mode, and the front surface is configured to support the splicing ends of two adjacent products. The positioning mechanism can quickly realize accurate positioning of the products through cooperation of the locking piece and the correcting piece, so that the positioning operation can be quickly realized when the products are spliced. In addition, the splicing accuracy of the two products can be ensured through the correcting piece. Once position deviation occurs after splicing, the correcting piece can be used for re-correction, and the efficiency is high and the maintenance difficulty is low.

This utility model relates to the field of tunneling technology, specifically to a tunneling face anti-sparging device. It includes a top beam lug mounted on the front beam of the machine-mounted support top beam. A main protective frame is located below the top beam lug, rotatably connected to the inner wall of the top beam lug. A hydraulic cylinder is rotatably connected to the inner wall of the top beam lug, with its output end rotatably connected to the inner wall of the main protective frame. Secondary protective frames are rotatably connected to both sides of the main protective frame. An extension component is provided on the inner wall of the secondary protective frames to expand the overall protection area. This utility model, by installing the top beam lug on the front beam of the machine-mounted support top beam, uses the hydraulic cylinder to rotate the main and secondary protective frames, placing them in a protective posture. Then, the secondary protective frames are rotated and positioned using a positioning component. Finally, a flexible protective net is installed on the main and secondary protective frames, thereby achieving effective full-section protection of the tunneling face and reducing the occurrence of sparging injuries.

The utility model discloses a filter core positioning device, including jar body, the lower surface of jar body is fixedly installed with the support ring, is provided with filter core positioning device on the upper portion of support ring, and filter core positioning device includes upper end cover and lower fixed ring, and the upper surface ring array of lower fixed ring has a plurality of support column, and the upper portion of support column outer surface is equipped with outer thread, and the inside of upper end cover is provided with the through -hole that is suitable for the support column, and upper end cover is connected with the outer surface of support column through the through -hole and slides, can be positioned to filter core through filter core positioning device, and the inner wall of jar body is equipped with the slide groove and annular recess and can be positioned and fixed to filter core positioning device, realizes the positioning operation to filter core, makes filter core installation process not to have the deviation, thereby guarantees the filter effect of filter core to water, through the square block on the lower surface limiting stopper block of cover and the limiting stopper slot on the rotating column of carding, can take out filter core positioning device from jar body in the reverse rotation of cover, and then conveniently installs and replaces filter core.

This utility model belongs to the field of cable cutting technology, and particularly relates to a cable rail retraction device for a cable steel cutting equipment. It includes a base, with an air roller bearing connected to one end of the base. A cable spool is fixedly connected to the outer wall of the air roller. A connecting frame is provided on one side of the air roller, and a reciprocating screw is bearing connected to the inner wall of the connecting frame. A transmission belt is provided at the connection between the air roller and the reciprocating screw. A threaded slider is threadedly connected to the outer wall of the reciprocating screw, and a guide block is fixedly connected to the top of the threaded slider. By setting an upper pressure block and a lower pressure block, a pneumatic cylinder drives a lifting frame to slide vertically along the outer wall of the cutting frame. The sliding of the lifting frame, through a positioning frame, causes the upper and lower pressure blocks at the bottom of the pressure plate to engage, achieving cable positioning and preventing cable misalignment, which would result in an uneven cable cutting surface. Then, the sliding of the lifting frame drives the cutter to cut the cable.
