Description

The displacement device and method of a kind of caterpillar chassis
Technical field
The present invention relates to a kind of displacement device of caterpillar chassis and method, belong to mechanical field.
Background technology
For the engineering truck using caterpillar chassis, especially hoisting machinery wishes to ensure that in the process of walking Preferably by property, and in job states such as liftings, it would be desirable that keep more preferable stability.It is as shown in Figure 1 caterpillar chassis A kind of conventional design, the mechanism for ensure it is good bevel angle α is increased crawler belt by property, under overall operation state Stability is determined by L.
Fig. 1 is caterpillar chassis arrangement form commonly used in the prior art, and caterpillar chassis is because its tractive force is big, grounding pressure Small, the features such as cross-country ability is good, and stability is good, and radius of turn is small, be widely used crawler type in fields such as engineering machinery Chassis refers to ability by certain road conditions by property, and certain trim angle of track is beneficial to carry cross-country traveling ability.Complete machine Stability is to influence the key index of engineering truck transaction capabilities, and its maximum will be directly affected for the machinery such as crane and is risen Weight, the key parameter that its stability is influenceed for caterpillar chassis engineering truck be complete machine bearing length or support away from From size L that is, shown in Fig. 1.How under the conditions of ensureing complete machine by property etc., increase bearing length, improve complete machine stability It is the key issue to be solved in design.
Under prior art conditions, it is the stability of increase overall operation state, some are to increase L by increasing vehicle commander Size.The mode of some increase caterpillar chassis engineering truck stability, mainly using supporting leg.By supporting leg under job state Stretch out and be supported in ground, increase the length of support.However, being supported using supporting leg, the space cloth of complete machine is on the one hand had a strong impact on Put and weight, and it is relative complex to operate, it is with high costs.Therefore, under the prior art, supporting leg is generally to give up, directly Using chassis supports, the requirement of stability is realized by the way of chassis is lengthened.
The content of the invention
The present invention is intended to provide a kind of displacement device of caterpillar chassis, by a kind of special modified gear, is ensureing Walking states by property on the premise of, improve the stability under job state, and stability will directly determine engineering working vehicle Performance.
The invention provides a kind of displacement device of caterpillar chassis, including crawler tension wheel, driving wheel, hydraulic cylinder, band Wheel, directive wheel, crawler belt, modified gear, modified gear are located at before and after chassis, and modified gear is by driving wheel, guide wheel group into triangle Frame structure, deflection function is realized by displacement hydraulic cylinder piston rod telescopic drive modified gear spinning movement;Directive wheel includes row Sail directive wheel and conjugate directive wheel, the displacement directive wheel traffic direction of side is opposite before and after chassis;
Track takeup is provided with above traveling directive wheel, track takeup is made up of tensioning wheel, hydraulic tensioning cylinder, tensioning Wheel is connected with hydraulic tensioning cylinder, and its work is driven by hydraulic tensioning cylinder;
The displacement hydraulic cylinder and hydraulic tensioning cylinder cylinder barrel are articulated with car body.Driven by Hydraulic Cylinder modified gear rotary motion, realize The increase of chassis supports distance.
In said apparatus, modified gear realizes the switching of chassis two states, the liftoff guarantee bottom of driving wheel under transport condition Disk is preferably by property, in the case where needing to increase the operating mode of complete machine stability, modified gear by displacement Driven by Hydraulic Cylinder before chassis, Displacement is realized in traveling directive wheel rotation afterwards, is grounded with driving wheel, is increased the support distances of crawler body.
In said apparatus, while crawler belt is conjugated, the needed length of crawler belt is varied from, and is filled by crawler tensioning Put and pre-save certain length deposit, and crawler belt is ensured by control of the track takeup for the power output of hydraulic cylinder Tension effects.
The invention provides a kind of displacement method of caterpillar chassis, including herein below:
When vehicle needs higher complete machine stability, the first displacement Driven by Hydraulic Cylinder left abomasal displacement mechanism is around traveling directive wheel Center of circle O1Carry out rotate counterclockwise, center of circle O of the second displacement Driven by Hydraulic Cylinder right abomasal displacement mechanism around traveling directive wheel2Carry out suitable Hour hands rotate, and now driving wheel acts on ground, and the support distances of complete machine increase L+2 Δ L by the L of transport condition, complete machine it is steady The qualitative growth because of support distances gets a promotion;
When needing to switch under the not high operating mode of transport condition or stability requirement, two modified gear reverse movements are realized multiple Position.Under the state, driving wheel is liftoff, and chassis has more preferably passing through property.
In the above method, when two states switch, the needed length of crawler belt changes.Therefore protected by tensioning apparatus Certain length deposit is deposited, when switching to job state from transport condition, hydraulic tensioning cylinder piston rod stretches out release crawler belt storage It is standby, and ensure certain tension effects by hydraulic tensioning cylinder active force.When switching to transport condition from job state, tensioning Hydraulic cylinder piston rod retraction withdraws crawler belt deposit, similarly ensures the tension effects of demand by hydraulic tensioning cylinder active force.
In the present invention, on the premise of whole length is not increased, do not influence chassis by property, adjusted and carried out using modified gear The bearing length of band, realize the lifting of complete machine stability.
Beneficial effects of the present invention:
This technology, using a set of special mechanism change Track gear, adds complete machine on the premise of meeting chassis by property Stability.And the set mechanism is not take up space of getting on the bus, and weight is relatively light, and cost is relatively low.
