Problems solved by technology

[0007] When the existing trailer technology is used for road transportation and rail transportation, the tailstock and vehicle frame with suspension cannot be turned up, and the position of the trailer in the height direction cannot be changed in the way of turning up. When large-scale equipment When transporting, it is impossible to meet the requirements of the road transport limit and the railway transport limit at the same time

Embodiment 1

[0040] As a preferred embodiment of the present invention, it includes a chassis tailstock 5 and a chassis seat frame 6, on which the chassis tailstock 5 is fixedly mounted with an overturn support 8, and the chassis tailstock 5 is hinged to the chassis seat frame 6 through the overturn support 8 , the chassis tailstock 5 rotates around the hinge center to make the chassis tailstock 5 turn up and down, refer to the attached manual figure 1 , that is, a schematic diagram of the structure of the inverted state of the present invention is given. When the chassis tailstock 5 is turned up, the height between the chassis seat frame 6 and the ground can be reduced, so that the large-scale The device 15 is also lowered in height.

Embodiment 2

[0042] As yet another preferred embodiment of the present invention, the overturning support 8 is provided with an overturning support shaft 3, and the support base 9 is fixedly installed on the chassis seat frame 6, and the overturning support shaft 3 runs through the overturning support 8 and the support base 9, The chassis tailstock 5 is hinged with the chassis seat frame 6 through the turning support shaft 3. When the goods are loaded on the chassis seat frame 6, the chassis tailstock 5 turns upwards. At this time, the turning support 8 also turns over together, and the support Seat 9 then does not overturn, and support seat 9 moves downward gradually along with chassis seat frame 6. Such a structural form makes the turning over of the chassis tailstock 5 more gentle, and the rest are the same as in Embodiment 1.

Embodiment 3

[0044] Refer to the attached image 3, as another preferred embodiment of the present invention, a spring torsion accumulator 1 is installed between the support bases 9, the spring torsion accumulator 1 includes a pin shaft, a torsion spring 10 sleeved on the pin shaft and a torsion spring sleeved on the torsion The outer tube 11 outside the spring 10, the two ends of the pin shaft are fixed on the support seat 9, one end of the torsion spring 10 is fixed on the pin shaft, and the other end of the torsion spring 10 is fixed on the outer tube 11, under the action of the torsion spring 10 The outer tube 11 is driven to rotate, and the outer tube 11 is connected with the chassis tailstock. There are three spring torsion accumulators 1 , and the outer tubes 11 of every two spring torsion accumulators 1 are connected and driven by a link mechanism 2 . The turning support 8 and the support seat 9 are respectively provided with a marching state locking pin hole 12 and a turned over ...

Abstract

The invention discloses a rotating mechanism of a trailer tail frame, and relates to the technical field of structures of trailer tail frames. The rotating mechanism of the trailer tail frame comprises a chassis tail frame and a chassis base framework, wherein an overturning support is fixedly arranged on the chassis tail frame, the chassis tail frame is hinged to the chassis base framework through the overturning support, and the chassis tail frame rotates around a hinged center so that the chassis tail frame can overturn upwards and downwards. By means of the rotating mechanism of the trailer tail frame, a trailer can be adjusted in the height direction in road transportation and railway transportation, and meanwhile the requirement for limits of the road transportation and the railway transportation can be met.

Description

[0001] technical field [0002] The invention relates to the technical field of trailer tailstock structures, in particular to a trailer tailstock rotating mechanism that can meet the requirements of road and railway transportation. Background technique [0003] The total weight of the trailer is called a trailer by itself, and usually a trailer is also referred to as a trailer. Features: It is a vehicle that has no power itself, is independently loaded, and relies on other vehicles for traction. A trailer is a non-powered road vehicle that needs to be towed by a car to carry people or goods due to its design and technical characteristics. A semi-trailer is a trailer whose axle is positioned behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is fitted with a hitch that transmits horizontal or vertical forces to the tractor. That is, part of the total weight of the trailer is borne by the tractor. Its characteristics: it has no power itself,...
