Telescopic positioning rail clamping device

Abstract

A telescopic positioning rail clamping device is characterized in that a mine rail gauge is laid according to a standard, and two sides are symmetrically arranged by taking a hole A as a central point; the track inner clamping plate is arranged on the inner side of the mining track and is fixed by a special bolt; a guide wheel is arranged on the outer side of the mining track; the guide wheel is arranged in the connecting rod, a groove is formed in the connecting rod, bolt holes are formed in the connecting rod, and the guide wheel is connected with the connecting rod through bolts. A rotating pin shaft is arranged at the upper part of the connecting rod and is welded with the connecting rod; the two ends of the rotating pin shaft are inserted into a sheath to form a rotating mechanism; the sheath is welded with the lower connecting plate; a cylinder body fixing seat is arranged in the middle of the man-riding vehicle base, the upper portion of the fixing seat is welded to the man-riding vehicle base, the lower portion of the fixing seat is fixedly connected with a double-piston hydraulic cylinder through a U-shaped fixing bolt, piston rods at the two ends of the double-piston hydraulic cylinder are connected with hinge seats through pin shafts respectively, and the hinge seats are arranged in the middle of a connecting rod. The structure is compact and simple, the maintenance amount is small, the operation is stable, the performance is stable and reliable, the barrier-free operation is realized, and the application and popularization value is great.

Description

technical field [0001] The invention relates to a clamping rail device for pedestrians and vehicles in undulating lanes of mines, in particular to a retractable positioning clamping rail device. Background technique [0002] We know that common-rail pedestrian vehicles in coal mines lack awareness of safety precautions, accidents occur frequently, and sideways rollovers often occur; and when pedestrian vehicles pass through turnouts, they must use special turnouts, which increases the difficulty of work and reduces efficiency. Contents of the invention [0003] In order to solve the frequent occurrence of sideways and rollovers; and when pedestrians and vehicles pass through the turnout, special turnouts must be used, which increases the difficulty of work and reduces efficiency. Therefore, the present invention provides a retractable positioning rail device; the device The performance is stable and reliable, and when pedestrians pass through the turnout, no special turnou...
