Horizontal posture adjusting mechanism of girder transporting vehicle when girders are transported on curved section transverse slope

Abstract

The invention discloses a horizontal posture adjusting mechanism of a girder transporting vehicle when girders are transported on a curved section transverse slope. The horizontal posture adjusting mechanism comprises a girder transporting vehicle body, a balance support and balance oil cylinders, wherein end supporting frames are arranged at two ends of the girder transporting vehicle body respectively, and the balance support is arranged above the girder transporting vehicle body. The horizontal posture adjusting mechanism has the beneficial effects that the balance oil cylinders at the twoends of the end supporting frames drive the balance support to be dragged and adjusted through hydraulic shafts I, the balance support and precast girders are dynamically adjusted by the balance oil cylinders in real time, and the end supporting frames are overturned and adjusted around a balance hinge, so that the balance support always keeps a horizontal state; on one hand, the postures of the precast girders are guaranteed to be horizontal and the mechanism is quickly and efficiently leveled when the precast girders are transported on different transverse slopes; on the other hand, great stability and safety of the girder transporting vehicle when transporting girders work are guaranteed, the precast girders are prevented from toppling and overturning from the girder transporting vehicle, and meanwhile, the collision loss between the precast girders and the girder transporting vehicle body, the balance support and a turntable is also reduced.

Description

technical field [0001] The invention relates to a horizontal attitude adjustment mechanism, in particular to a horizontal attitude adjustment mechanism when a beam transport vehicle transports beams on a cross slope in a curved section, and belongs to the application technical field of a horizontal attitude adjustment mechanism when a beam transport vehicle transports beams on a cross slope in a curved section . Background technique [0002] Both railways and highways are designed with cross slopes on curved sections. The faster the design speed of the road, the larger the cross slope; Such accidents are more likely to occur on rainy and snowy days without hardened road surfaces. [0003] The existing beam transport vehicle does not have a horizontal attitude adjustment mechanism. When the existing beam transport vehicle transports beams on a cross slope in a curved section, the method of adding support is used when the cross slope is small; when the cross slope is large, t...

Problems solved by technology

[0003] The existing beam transport vehicle does not have a horizontal attitude adjustment mechanism. When the existing beam transport vehicle transports beams on a cross slope in a curved section, the method of adding support is used when the cross slope is small; when the cross slope is large, the method of adding pads on the downhill in advance ; When transporting beams in both straight and curved sections, the above methods are difficult to quickly solve the problems of easy rollover of beam transport vehicles and prefabricated beams, large safety hazards in use, and inconvenient and efficient adjustment of prefabricated beams to a horizontal state.
