Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-3, the utility model comprises case beam 1 and is sheathed on the bracket 2 in case beam, and case beam 1 is the quadra structure that one group of crossbeam 11 and one group of longeron 12 are connected to form, and establishes the rectangular box steel of cavity in crossbeam 11 and longeron 12 are.In the present embodiment, longeron 12 length direction is longitudinally, and crossbeam 11 length direction is laterally.
Case beam 1 one end end face offers the hole 3 corresponding with bracket 2, and hole 3 passes in and out relative to case beam 1 for bracket.Case beam 1 inner top is epiplastron, epiplastron welds two cushion blocks, 4, two cushion blocks 4 in epiplastron horizontally set, the transverse ends of the corresponding bracket 2 of cushion block 4; Case beam 1 inner bottom part is bottom web, and bottom web is provided with strengthens backing plate 5, the upper and lower surface of bracket 2 respectively with cushion block 4 with strengthen 5, backing plate and contact.Be provided with locating hole 7 bottom case beam 1, be provided with positioning convex below cushion block 4, positioning convex is positioned at locating hole 7.Positioning convex coordinates the frictional force produced when avoiding bracket 2 to move that reinforcement backing plate 5 is slided to misplace with locating hole 7.
Case beam 1 bottom web front end is provided with laterally steering pivot pin 6, as shown in Figure 4, guiding pivot pin 6 comprises: pivot pin 61, flange 62, pad 63, bolt 64, pivot pin 61 is T word pin, laterally inserted longeron 12, pivot pin 61 afterbody circumferentially has screw, flange 62 is positioned at longeron 12 external surface, flange 62 is connected with pivot pin 61 end by bolt 64, is lined with pad 63 between flange 62 and bolt 64.Pivot pin 61 circumferential edges contacts with bracket 2 soffit.
The drive unit of bracket 2 is hydraulic jack 8, and hydraulic jack comprises holder 81 and telescopic end 82, and holder 81 is fixedly connected with case beam longeron 12 upper surface, and telescopic end 82 is connected with bracket 2 by guiding device 9.Guiding device 9 comprises longitudinal bar hole 91 that case beam surface is offered and the prerotation vane 92 being positioned at bar hole 91, is fixedly connected with, is fixedly connected with below prerotation vane 92 with bracket 2 above prerotation vane 92 with the telescopic end 82 of telescopic oil cylinder 8.
When hydraulic jack 8 drives bracket 2 to move, telescopic end 82 extends and makes prerotation vane 92 outwards mobile in bar hole 91, prerotation vane 92 drives bracket 2 outwards movement from hole 3, now, bracket 2 upper and lower surface cushion block 4 and strengthen backing plate 5, guiding pivot pin 6 between outwards skid off.Pivot pin 6 pivot pin 61 that leads during slip carries out guide and limit to it, and when bracket 2 moves, pivot pin 61 rolls, and bracket 2 is led not bite.When being used by pile equipment, support for face contact force is transmitted between bracket and case beam, support bracket lifting surface area when transmitting huge stress is increased, and power transmission is more even.
