Abstract
The utility model provides a crawler lifting and damping mechanism for a crawler type high-altitude operation car. The crawler lifting and damping mechanism is characterized by comprising a crawler lifting mechanism (2) connected with a crawler (1), a crawler oil cylinder (3) and a damping mechanism, wherein the crawler lifting mechanism (2) comprises four bracket shafts that are arranged in parallel with one another and are enclosed with one another to form a cylinder, thereby forming four parallelogram mechanisms that are arranged at the upper part, the lower part, the internal part and the external part respectively; and a damping spring (12) is arranged between an oil cylinder supporter (4) and the crawler oil cylinder (3). By adopting the crawler lifting and damping mechanism, the difficulty of converting the existing walking mode of the high-altitude operation car into the crawler walking mode can be overcome; the lifting action of the crawler can be realized successfully before and after the operation; the vibration can be reduced greatly when the crawler shrinks and walks; and furthermore, the operation is safe and reliable and the rotation is flexible. When the crawler goes up and down and walks, the reaction force of the ground surface is transmitted to the spring by the oil cylinder so as to counteract and reduce the vibration, so that the reaction force is not directly acted on an underframe so as to avoid the vibration of the whole car, thereby leading the whole car to run stably, and prolonging the service life of the high-altitude operation car.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: be used for the crawler belt lifting damping of crawler type aerial platform as shown in fig. 1, comprise and crawler belt 1 bonded assembly crawler belt lifting mechanism 2, crawler belt oil cylinder 3 and damping.
As shown in Figure 8, be the crawler belt installing condition of crawler type aerial platform, the huge crawler belt of car body both sides need be mentioned by the crawler belt oil cylinder 3 on the underframe 5 when operation, and puts down supporting leg, thereby complete vehicle weight is transferred on the supporting leg.As shown in Figure 1, the top and crawler belt oil cylinder 3 bottoms of the crawler belt lifting mechanism 2 of directly captiveing joint with crawler belt 1 are hinged, and the cylinder support 4 on the top of crawler belt oil cylinder 3 and the Operation Van's underframe 5 is hinged.
Structure as Fig. 1, crawler belt lifting mechanism 2 shown in Figure 7, described crawler belt lifting mechanism 2 comprises four support shafts that are parallel to each other and surround cylindricality, form upper and lower, inside and outside four parallel-crank mechanisms, the two ends of the outside parallel-crank mechanism that is formed by upper plate outer support axle 6 and lower plate outer support axle 15 are hinged with crawler belt support 7 respectively, and the two ends of the inboard parallel-crank mechanism that is formed by upper plate inner support axle 9 and lower plate inner support axle 16 are hinged with the erecting frame 11 that is welded on the underframe 5 respectively.Described upper plate outer support axle 6 is fixedly mounted on the upper junction plate 13 with upper plate inner support axle 9, and lower plate outer support axle 15 is fixedly mounted on the lower connecting plate 14 with lower plate inner support axle 16.The middle part of described upper junction plate 13 is provided with cylinder support 8.
Four support shafts are formed a space multistory parallel-crank mechanism.Crawler belt oil cylinder in this mechanism promotes parallelogram bracket motion on the crawler belt crane, promote and crawler belt fixed mount pivotally attached space multistory parallelogram motion, because the installation site of underframe 5 has determined crawler belt oil cylinder and crawler belt lifting support angled, the horizontal component of force of crawler belt oil cylinder promotes parallelogram and drives the crawler belt horizontal motion, the vertical component of crawler belt oil cylinder promotes parallelogram and drives the crawler belt perpendicular movement, thus the lifting of realization crawler belt and flexible.
Horizontal component of force promotes the parallelogramming deflection of upper plate outer support axle 6 and upper plate inner support axle 9 compositions, and support is protruding, and it is protruding to drive crawler belt 1; The parallelogramming deflection of vertical component promotion upper plate outer support axle 6 and lower plate outer support axle 15 compositions is out of shape downwards simultaneously, and support stretches out downwards, drives crawler belt and stretches out downwards.Use the junction of parallel-crank mechanism member to contact, can transmit bigger power as face; And oil cylinder power is converted into horizontal component of force and vertical component by the effect that parallel-crank mechanism is divided into conversion and transmits power, rather than rigid stretches out under tiltedly, and the antagonistic force of generation is less.
As being provided with damping spring 12 in the cylinder support as described in Fig. 2,3,64 and between the crawler belt oil cylinder 3.The top of described crawler belt oil cylinder 3 is connected in the slotted hole 17 on the cylinder support 4 by oil cylinder bearing pin 10, the parallel axes of the axis of described slotted hole 17 and crawler belt oil cylinder 3.Described damping spring 12 is disk springs.
As Fig. 4,5, the top of crawler belt oil cylinder 3 is connected with cylinder support 4 on being fixed in underframe 5 by oil cylinder bearing pin 10, and the hole on the cylinder support 4 is a slotted hole, and crawler belt oil cylinder 3 can have displacement along axis, and the anchor shaft of oil cylinder cylinder bottom links to each other with axle on the bearing by spring.When the crawler belt lifting, ground-surface antagonistic force is delivered on the spring by oil cylinder, is offset, and reduces vibrations.
Oil cylinder bearing pin 10 produces displacement along axis, while compression shock absorption spring 12, rather than directly act on the vibrations that cause car load on the underframe.Oil cylinder bearing pin 10 mounting holes on the cylinder support 4 are a slotted hole, and oil cylinder bearing pin 10 can have certain displacement along axis in slotted hole 17; Antagonistic force during caterpillar drive all acts on the spring, and damping spring 12 distortion produce displacement, and the other end of crawler belt oil cylinder 3 is along the oil cylinder axial-movement.The application force that produces of deflection of spring contends with it subsequently, reach balance after, this end of crawler belt oil cylinder 3 underframe no longer moves, and reaches dynamical equilibrium.Otherwise in like manner.Damping spring adopts the big belleville spring of rigidity, can bear car load big antagonistic force to oil cylinder when the crawler belt lifting with small deformation, reduces being rigidly connected to the impact of car load, reduces vibrations.All hinged places all connect with the steel pivot pin.
