Problems solved by technology

[0003] In the construction process of civil engineering, it is often necessary to carry and translate large-scale structural parts and large-volume box girders. Some large-scale and slow-moving mechanical equipment is very time-consuming when driving by itself, so traction is required When pulling large-scale equipment, machinery or materials, the tractor may encounter obstacles such as bumps or pits on the road surface under the harsh construction roads of the construction site, which will cause the car body to shake seriously. The adjustment is poor, and it is prone to the phenomenon of uneven force and dumping. Afterwards, the weight on the trailer tilts, and the change of its center of gravity position will cause the trailer to overturn, thereby causing the tractor connected to it to overturn, resulting in casualties, and accidents

Embodiment 1

[0037] Embodiment 1, please combine the attached Figure 1-16 , a tractor for civil engineering construction, comprising a tractor body 1, and a connecting device 2 fixed on the tractor body 1, the connecting device 2 is connected to the trailer described herein, and the trailer can carry large-scale objects in civil engineering mechanical equipment and materials;

[0038] The connecting device 2 includes a fifth wheel 3 and a horizontal plate 4. The fifth wheel 3 is connected to the upper end of the horizontal plate 4 by rotating back and forth. At the same time, it allows the traction seat 3 and the trailer on it to deflect at a certain angle along the front and rear directions of the vehicle body along the rotating shaft installed under it, which can meet the needs of the two vehicles when the tractor body 1 and the rear trailer need to go up and down. The requirement for up and down slopes between bodies is characterized in that it also includes an inclination protection ...

Embodiment 2

[0040] Embodiment two, on the basis of embodiment one, in conjunction with the attached Figure 6-8 and 13 and 15, the support device 10 includes a base 13 connected to the fixed plate 6, and the upper surface of the base 13 is provided with a semicircular first semicircle that is placed in the base 13 and matches the cylindrical protrusion 9. A chute 14 ensures that the cylindrical projection 9 can be reliably placed in the base 13, and the upper surface of the base 13 is provided with a semicircular second chute 15 matching the main shaft 8 in the direction of the main shaft 8 to ensure The main shaft 8 can be reliably placed in the base 13, and the second chute 15 is transparent along the axial direction. The bump 9 is slidingly fitted with the first chute 14. Due to the limitation of the cooperation between the cylindrical bump 9 and the base 13, the main shaft 8 will not be displaced in the base 13 along the front and rear direction of the vehicle body. Combined with two...

Embodiment 3

[0041] Embodiment three, on the basis of embodiment 1, in conjunction with appended Figure 9-12 and 14 and 16, the driving device 11 includes a first set of rods 29 and a second set of rods 30 that are hinged at the lower end of the horizontal plate 4 and are placed in parallel, and the first set of rods 29 is slidably fitted and fixed on the fixed plate 6. The first telescopic rod 31 of the second set of rods 30 is slidably fitted with a second telescopic rod 32 fixed on the fixed plate 6, and a second telescopic rod 32 is connected between the first set of rods 29 and the first telescopic rod 31. A spring 33, a second spring 34 is connected between the second set of rods 30 and the second telescopic rod 32, and a third rack 35 is connected to the side of the first set of rods 29 facing the main shaft 8, so A fourth rack 36 is connected to the side of the second set of rods 30 facing the main shaft 8. When the horizontal plate 4 is inclined, the first set of rods 29 and the ...

Abstract

The invention provides a civil engineering construction towing tractor. The problem that a towing tractor body and a trailer are turned over together when the trailer is turned over is solved. According to the technical scheme, the civil engineering construction towing tractor comprises a towing tractor body and a connecting device on the towing tractor body, and the towing tractor body and the trailer are connected together through the connecting device. When the trailer is turned over, the trailer drives the towing tractor body to be also turned over, at the moment, the connecting device between the towing tractor body and the trailer drives a driving device due to tilt of a transverse plate, thus a sector gear drives a supporting device, a top cover in the supporting device is opened, and a main shaft is not wrapped with the top cover any more, so that disengagement between the trailer and the towing tractor body is achieved, the towing tractor body is not turned over due to turning-over of the trailer, and the life and property safety of people in the towing tractor body is ensured.

Description

technical field [0001] The invention mainly relates to the technical field of traction equipment, in particular to a tractor for civil engineering construction. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It refers to the materials, equipment and technical activities such as surveying, design, construction, maintenance and repair, as well as the objects of engineering construction. That is, various engineering facilities built on the ground or underground, on land or in water, that directly or indirectly serve human life, production, military affairs, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, Power stations, airports, offshore platforms, water supply and drainage, and protection projects, etc. [0003] In the construction process of civil engineering, it is often necessary to carry and translate large-scale struct...
