DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0015] As Figures 1-3 shown, a mine vehicle rail gripper includes a trapezoidal support plate 1, the trapezoidal support plate 1 is placed symmetrically left and right, the trapezoidal support plate 1 is provided with a pin hole 2 and a long slot hole 3, the pin holes 2 are symmetrically opened on both sides below the trapezoidal support plate 1, and the left and right symmetric pin holes 2 are nested with a pin shaft 4, the long slot hole 3 is opened in the middle above the trapezoidal support plate 1, through slots 5 are symmetrically opened on both sides of the top of the long slot hole 3, a transmission rack 6 is installed and fixed at the inner end of the left through slot 5 through screws, a support beam 7 is nested in the long slot hole 3, the support beam 7 is provided with a baffle 8 and a central shaft 9, the baffle 8 is symmetrically installed and fixed at both ends of the support beam 7 through screws, the central shaft 9 is integrally formed and connected to the middle of the support beam 7, a transmission gear 10 and a set screw 11 are arranged on the central shaft 9, the transmission gear 10 is connected to the upper end of the central shaft 9 by interference fit through a bearing, the set screw 11 is connected to the middle of the central shaft 9 by threads, a handwheel 12 and an extrusion plate 13 are arranged on the set screw 11, the handwheel 12 is installed and fixed on the top of the set screw 11 through screws, the extrusion plate 13 is installed and fixed on the bottom of the set screw 11 through screws, and the transmission gear 10 is meshed and connected with the transmission rack 6.

[0016] Specific usage method: Place the trapezoidal support plates 1 symmetrically on both sides of the track. Then, push and pull one side of the trapezoidal support plate 1 to move inward along the support beam 7. The inward movement of one side of the trapezoidal support plate 1 drives the transmission rack 6 on that side to move inward. The inward movement of the transmission rack 6 on one side drives the transmission gear 10 to rotate. The rotation of the transmission gear 10 drives the transmission rack 6 on the other side to move inward. The inward movement of the transmission rack 6 on the other side drives the trapezoidal support plate 1 on the other side to move inward along the support beam 7. At this time, the trapezoidal support plates 1 move relatively inward to clamp the track. Then, insert the pin shaft 4 into the symmetrically arranged pin holes 2 on the left and right, and at the same time, the position of the pin shaft 4 is at the lower plane of the track I-beam. Finally, rotate the handwheel 12 to drive the set screw 11 to rotate. The rotation of the set screw 11 drives the pressing plate 13 to move downward along the central shaft 9 and abut against the upper plane of the track I-beam. At this time, the trapezoidal support plates 1 are fixed on the track.
