Abstract

The invention discloses an advancement support device for a spreading machine, which comprises a driving crawler belt, a fixing bracket, a lifting inner sleeve, a thrust oil cylinder, a slide block check ring, an inner sleeve lifting locating ring, an outer fixing sleeve and a reciprocating motion bearing, wherein the fixing bracket is fixedly arranged above the driving crawler belt; the lifting inner sleeve is fixedly arranged on the fixing bracket; the thrust oil cylinder is arranged in an inner cavity of the lifting inner sleeve; the slide block check ring is mounted on an outer wall at the bottom of the lifting inner sleeve in a sleeving manner; the inner sleeve lifting locating ring is mounted on the outer wall of the lifting inner sleeve above the slide block check ring in a sleeving manner; the outer fixing sleeve is arranged above the inner sleeve lifting locating ring; the reciprocating motion bearing is arranged between the outer fixing sleeve and the lifting inner sleeve; and the top of the outer fixing sleeve is fixedly connected with the top of a cylinder body of the thrust oil cylinder. The device has the advantages that the synchronous operation of lifting and rotation is controlled by hydraulic driving, and the lifting and the rotation are not mutually intervened; the lifting is controlled by the hydraulic driving, so that a host can adjust a balance degree more flexibly; the rotation is controlled by the hydraulic driving, so that the host can travel towards any angle; and construction under any environmental condition can be coped with.

Description

Technical field:

[0001] The invention relates to a traveling support device for a paver, which belongs to equipment for using the paver. Background technique:

[0002] The existing slipform paver crawler steering mechanism is realized with an oil cylinder push-pull device, and in this way the steering angle is limited to a certain extent and cannot run laterally. The crawler lifting and rotating positioning mechanism adopts flat key positioning and outer folding reinforcing plate. The contact surface between the key and the keyway is not strong enough, and the outer folding reinforcing plate makes up for the strength. If the key is thicker, the keyway must be opened deeper, so the lifting column material must be thicker. The weight of the whole machine is increased. Invention content:

[0003] The first object of the present invention is to provide a paver running support device with stable lifting.

[0004] The second object of the present invention is to provide a pave...
