In figure, sequence number illustrates: the support of Bridge 1 body, 2 curve tracks, 3 hydraulic pushing oil cylinders, 4 horizontal earrings, 5 bearing pins, 6 base plates, 7 rollers, 8 compressor arms, 9 holddown springs, 10 casings, 11 top boards, 12 chutes, 13 cambered surface push pedals, 14 high-strength bolts, 15 right clapboards, 16 left clapboards.
Detailed description of the invention
As shown in Figure 1-Figure 3, this bridge curve track pushing tow clamping device, comprise casing 10, be provided with horizontal earrings 4 outside casing 10 and be connected with hydraulic pushing oil cylinder 3 with bearing pin 5 by horizontal earrings 4, hydraulic pushing oil cylinder 3 other end is connected with steel bridge bridge support 1, and bridge support 1 can slide (see Fig. 1) on curve track 2.Top board 11 is welded with in casing 10, high-strength bolt 14 is utilized to be fixed with a left side successively below top board 11, right clapboard 16, 15 and base plate 6, left, right clapboard 16, formed between 15 and insert the space of curve track 2 and left, right clapboard 16, 15 homologous thread track 2 side symmetries offer organizes triangular groove more, in the present embodiment, the quantity of triangular groove is 3 groups, roller 7 is provided with in each triangular groove, an interior inclined-plane of triangular groove is built-in is provided with holddown spring 9, the outer end of holddown spring 9 is connected with compressor arm 8, compressor arm 8 front end ejection roller 7 make itself and triangular groove another in inclined-plane and curve track 2 side stick together, for ease of closely reclining with roller 7, the thrust of holddown spring 9 is passed to greatest extent roller 7 and make its grip track side, compressor arm 8 front end is provided with the cambered surface push pedal 13 matched with roller 7 circumference side.The triangular groove position of top board 11 and the corresponding left and right clapboard 16,15 of base plate 6 is provided with the chute 12 slided for roller 7, and the angle of inclination of chute 12 is consistent with the angle of inclination on the inclined-plane of the roller 7 that reclines of respective side clapboard.In the present embodiment, the annular knurl process of hardening is carried out on steel roller 7 surface, and the inclined-plane that clapboard contacts with roller 7 also carries out hard surfacing process, to make surface hard and increasing friction force.
Operating principle: after hydraulic pushing oil cylinder 3 promotes casing 10, clapboard level moves backward, roller 7 is because moving backward by holddown spring 9 thrust is asynchronous, be subject to the extruding of clapboard inclined-plane simultaneously, thus compress curve track 2 side rapidly, clamping force increases with hydraulic pushing oil cylinder 3 thrust and increases, and this clamping force forms propulsive thrust and the frictional force of supporting bridge 1 on curve track 2 balances, and completes self-balancing pushing action; When hydraulic pushing oil cylinder 3 pulls in the backhaul of casing 10, the inclined-plane that top board 11 has with the chute 12 of base plate 6 is pulled away from curve track 2 side by oblique for each roller 7, remove clamped condition, but under the effect of holddown spring 9 and compressor arm 8, continue the curve track 2 that reclines, prepare to carry out pushing action next time.
