Embodiment 1

[0030] like figure 1 As shown in the figure, this embodiment discloses a variable-distance operation truck, which includes a body 1, wheels 2 and a power unit, and several sets of quadrilateral double-variable hangers 3 are arranged at the bottom of the vehicle body 1; When the length of the body 1 of the vehicle is not large, the quadrilateral double-changeable hanger 3 is symmetrically installed on both sides of the rear end of the bottom of the vehicle body 1 through the lower body 4 and the upper body 5. When the length of the vehicle body 1 is relatively large At the time, the quadrilateral double-changeable hanger 3 is symmetrically installed on both sides of the bottom middle section and the rear end of the vehicle body 1 through the lower connecting hanging lugs 4 and the upper connecting hanging lugs 5 of the vehicle body.

[0031] Specifically, in this embodiment, the specific structure of the quadrilateral double-changeable hanger 3 is given, such as figure 1 As sh...

Embodiment 2

[0038] As a preferred mode of this technical solution, in addition to the above structure in Embodiment 1, as figure 1 As shown, a double-beam self-balancing bogie 15 is also provided in the middle of the front end of the bottom of the body 1, and the double-beam self-balancing bogie 15 is connected to the body 1 through the body connecting column 16 and the body bottom beam 17; Figure 5 As shown in -8, the double-beam self-balancing bogie 15 includes a main unit 18 , a secondary unit 19 , a vertical motion main body 20 , a vertical motion secondary body 21 and a force balance mechanism 22 .

[0039] like Figure 5 As shown in 7-7, the main combined body 18 includes four right-angle lifting lug connecting plates 28 and two bearing sleeves 29; right-angle lifting lug connecting plates 28 are symmetrically arranged on both sides of each bearing, and the outer wall of the bearing is connected to the right-angle lifting lug connecting plate 28. The lug connecting plates 28 are f...

Abstract

The invention discloses a variable-pitch operation carrier. The variable-pitch operation carrier comprises a carrier body and wheels, and a plurality of quadrilateral double-variable hanging frames are arranged at the bottom of the carrier body; the quadrilateral distance changing mechanism can drive wheels on the rear side of the vehicle body to swing by 180 degrees relative to the vehicle body, and the positions of the wheels on the rear side of the vehicle body are always kept parallel to the vehicle body. When the quadrilateral distance-changing mechanism drives the wheels on the rear side of the vehicle body to swing towards the front end of the vehicle body, the wheel distance on the rear side of the vehicle body is decreased, and the wheel base before and after the vehicle body is decreased; when the quadrilateral distance changing mechanism drives the wheels on the rear side of the vehicle body to swing by 90 degrees towards the two side ends of the vehicle body, the wheel distance on the rear side of the vehicle body is increased, and the wheel base between the front and rear sides of the vehicle body is increased; when the quadrilateral distance changing mechanism drives wheels on the rear side of the vehicle body to swing towards the rear end of the vehicle body, the wheel distance on the rear side of the vehicle body becomes small, and the wheel base between the front and back of the vehicle body becomes large. According to the variable-pitch operation van, the wheelbase and the wheel track can be changed through the quadrilateral double-variable hanging frame, and therefore the operation van can meet various operation environments.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a variable-pitch operation truck. Background technique [0002] A work vehicle is a four-wheeled vehicle loaded with special equipment or implements for special operations. The work vehicle needs to be able to adapt to various working environments. Most of the existing work vehicles use ordinary car bodies, and the wheelbase and wheelbase of the work vehicle cannot be adjusted, so that the existing work can only be performed in a relatively flat and wide area. It is not very suitable for narrow and bumpy mountain roads. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a variable-pitch operation truck, which can change the wheelbase and the wheelbase, so that the operation vehicle can not only drive on a relatively flat and wide road, but also can run on narrow roads. Driving on rough mountain roads to meet vari...
