A paver traveling steering support device

Abstract

The invention discloses a paver advancing, steering and supporting device. The paver advancing, steering and supporting device comprises an advancing device, a fixed support, a lifting column, a supporting body, a thrust oil cylinder, a rotation drive device and an oil way rotation connector. The fixed support is fixedly arranged on the upper portion of the advancing device. The oil way rotation connector is fixedly arranged on the upper portion of the fixed support. The rotation drive device is fixedly arranged at the upper end of the oil way rotation connector. The lifting column is vertically and fixedly arranged at the upper end of the rotation drive device. The lifting column and the supporting body are hollow cylinders which are arranged in an inside-outside sleeved mode and are of the same shape. The lifting column is arranged in an inner cavity of the supporting body. The top of the inner cavity of the supporting body is fixedly connected with the top of a cylinder body of the thrust oil cylinder. The thrust oil cylinder is arranged in an inner cavity of the lifting column. The top of a piston rod of the thrust oil cylinder penetrates through the inner cavity of the lifting column and the rotation drive device to be fixed into a piston rod fixing base on the top of the oil way rotation connector. A connection groove is formed in the top of the piston rod. An annular piston rod fixing groove corresponding to the connection groove is formed in the piston rod fixing base. Piston rod positioning steel balls are arranged in the piston rod fixing groove.

Description

[0001] Technical field:

[0002] The invention relates to the field of paver equipment, in particular to a paver traveling steering support device.

[0003] Background technique:

[0004] The existing slip-form paver crawler steering mechanism is realized by an oil cylinder push-pull device. In this way, the steering angle is limited 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.

[0005] The disadvantages of the existing paver travel support steering device mainly include: first, the existing steering device cannot realize 360 ​​° rotation without obstacles, because the hydraulic motor is inst...
