Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 4, Fig. 5, chassis stepping running gear disclosed in the utility model, comprise slide plate 1, corresponding arrange side 2, for be connected with the driving oil cylinder be fixed on chassis connecting panel 3, be welded on balance plate 4 before and after slide plate 1.Side 2 to be fixed on the downside of slide plate 1 and to form chute with slide plate 1, described side plate 2 comprises back-up block 21, the shape corresponding with backup block 21 is right-angled trapezium wedged block 22, base plate 23, cover plate 24, spring 25; Back-up block 21 is right-angled trapezium, the upper surface of back-up block 21 is fixedly connected with base plate 23 with slide plate 1 respectively with lower surface, form the sliding chamber that shape is isosceles trapezoid between the back-up block 21 that both sides are corresponding, the base plate 23 that both sides are corresponding has the guide groove 231 be parallel to each other with the waist in the sliding chamber of isosceles trapezoid; Wedged block 22 to be arranged in the sliding chamber that shape is isosceles trapezoid near back-up block 21 and can to slide by relative support block 21, the right-angle surface of wedged block 22 is jagged convex surface, the screens for blocking trolley running track is formed between the wedged block 22 that both sides are corresponding, wedged block 22 has the walking projection 222 corresponding with guide groove 231, when wedged block 22 is installed near back-up block 21, described walking protruding 222 falls in guide groove 231; Form region use cover plate 24 shutoff that shape is the corresponding wedged block 22 in base in the sliding chamber of isosceles trapezoid between the back-up block 21 that described both sides are corresponding, and be installed with spring 25 between cover plate 24 and wedged block 22.
As shown in Fig. 1, Fig. 3, Fig. 4, connecting panel 3 is fixed on the upside of slide plate 1, connecting panel 3 comprises riser 31, location side plate 32, positioning plate 33, described riser 31 is fixed on described positioning plate 33, and described location side plate 32 is fixedly mounted on described riser 31 side and is fixedly connected with positioning plate 33 with riser 31 simultaneously.Described riser 31 is two pieces and is the room of the push rod for holding chassis force application apparatus between corresponding riser 31, described riser 31 has and carries out spacing through hole to the push rod of described chassis force application apparatus.
The following is the motion flow of the utility model chassis stepping running gear:
Contact surface between back-up block 21 and wedge 22 is smooth without friction, and the contact surface friction coefficient between wedge 22 and track is comparatively large, and spring is in compressive state always.Power F is applied to chassis stepping running gear by driving oil cylinder, chassis stepping running gear applies the pressure perpendicular to contact surface by wedge 22, wedge 22 the bearing capacity of track, the elastic force of spring, the pressure of chassis stepping running gear and with the friction force combined action on rail contact face under keep static balance, with the increase putting forth effort F, friction force on track and wedge 22 contact surface is also larger, realizes auto-lock function.Drive the piston rod of oil cylinder to continue to stretch out, fixing device will provide support counter-force, and promote chassis and advance, chassis stepping running gear is motionless; When driving the piston rod of oil cylinder to regain, the tensile force f of generation drives the motion of chassis stepping running gear, and wedge 22 is no longer squeezed, and so wedge 22 and rail contact face will not have friction force, and realizes automatic unlocking function.Drive cylinder piston rod to continue to regain, back-up block 21 will be driven to move, and simultaneously under the effect of spring force, wedge 22 also will move.Chassis stepping running gear is along rail moving, and now chassis is motionless; Repeat above-mentioned steps, complete the advance of chassis.
The foregoing is only better embodiment of the present utility model, the utility model is not limited to above-mentioned embodiment, the structural modification that local is small may be there is in implementation process, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, and belonging within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
