Detailed description of the invention
As shown in Figures 1 to 4, the utility model mainly comprises frame 1, crossbeam 2, lifting driving assembly, pull bar 4, jack 5 and baffle plate 6, is described the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, frame 1 is matrix of the present utility model, and frame is section bar weldment, is provided with road wheel 11 in the bottom of frame, so that the walking of frame.Road wheel is provided with locking structure, so that when needing frame static, is avoided the rolling of roller by locking structure.Above frame, be provided with crossbeam 2, in the horizontal direction, crossbeam is static relative to frame, in the vertical direction, and crossbeam can frame move up and down relatively.As shown in Figure 3, be provided with the vertical leading screw 3 placed at the top of frame, the bottom of leading screw is rotatably installed in frame by bearing 12, and crossbeam is provided with the screwed hole coordinated with leading screw, and crossbeam is connected with threads of lead screw.When screw turns, the lifting of crossbeam just can be driven.For the lifting of gate beam, be respectively equipped with some guide posts 21 in the both sides of leading screw, guide post is the vertical circular metal bar placed, and the bottom of guide post is fixed in frame, and top and the crossbeam of guide post are slidably connected.As shown in Figure 2, guide post is provided with six, and is divided into two groups, and two groups of guide posts are separately positioned on the both sides of leading screw, and often group comprises three guide posts, and often organize three guide posts are positioned on leg-of-mutton three summits.Under the effect of guide post, move under crossbeam in the vertical direction.
Be installed with worm gear 31 in the bottom of leading screw, be provided with a pair bearing 13 at the top of frame, bearing is rotatablely equipped with worm screw 32, worm and wheel engagement fit.Worm shaft is fixed with driven wheel of differential 33, support 14 is also provided with at the top of frame, support is rotatablely equipped with drive bevel gear 35, the gear shaft of drive bevel gear is fixed with handle 35, by turning handle, drive the rotation of drive bevel gear, and then drive the rotation of driven wheel of differential, worm and worm wheel, the rotation of eventually with movable wire thick stick, realizes the elevating movement of crossbeam.Leading screw, worm gear, worm screw, drive bevel gear, driven wheel of differential and handle constitute and drive the lifting of beam lifting to drive assembly.
Be fixed with jack 5 in the side of crossbeam, be respectively equipped with a pull bar 4 in the both sides, front and back of jack, pull bar is that one end is provided with externally threaded circular metal bar, and the installation end of pull bar is fixed on the side of crossbeam.For tie-strut, between pull bar installation end and crossbeam, be provided with bearing diagonal.Certainly, the installation end of pull bar also can be hingedly mounted on crossbeam, or the installation end of pull bar extend in crossbeam, and coordinates mounting nuts on pull bar.Be provided with external screw thread at the free end of pull bar, coordinate mounting nuts 61 at the free end of pull bar, nut is fixed with baffle plate 6, and baffle plate is provided with through hole, and the aperture of this through hole is greater than the external diameter of pull bar, and through-bore axis and pull bar dead in line.
During use, by machine frame movement to working region, baffle plate is unloaded, the free end of pull bar is extend into in wheel, then baffle plate is contained on pull bar free end.Now be limited between baffle plate and crossbeam to wheel, the piston rod of jack is withstood on machine shaft, drive jack operation, like this, jack drives crossbeam to move to away to the side of wheel, will be left behind by pull bar to wheel from machine shaft, to realize the dismounting to wheel.
