Engineering vehicle

Abstract

The invention discloses an engineering vehicle which comprises a vehicle body, wheel sets and wheel driving mechanisms. The wheel sets are connected with the vehicle body through wheel adjusting devices. Each wheel adjusting device comprises a fixed connection rod, a movable connection rod and a hydraulic oil cylinder, wherein one end of the fixed connection rod is fixedly connected with the vehicle body, and the other end of the fixed connection rod is hinged to one end of the movable connection rod; the other end of the movable connection rod is fixedly connected with the corresponding wheel of the corresponding wheel set, one end of the hydraulic oil cylinder is hinged to the vehicle body, and the other end of the hydraulic oil cylinder is hinged to a rod body of the movable connection rod; and the hydraulic oil cylinder can be driven to drive the movable connection rod to move so as to adjust lifting of the corresponding wheel of the corresponding wheel set. According to the engineering vehicle, the wheel driving mechanisms are arranged on the wheels, not only is control over the wheels convenient, but also a vehicle head part is omitted, and the height of the engineering vehicle is lowered. The wheel adjusting devices can be used for adjusting lifting of the wheels at the two ends. The engineering vehicle has good obstacle crossing ability, and box culverts can be efficiently mounted in the large concrete box culvert construction process.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an engineering vehicle. Background technique [0002] Engineering vehicles are the backbone of modern construction projects. The emergence of various types of engineering vehicles has doubled the progress of construction projects, greatly reduced manpower and material resources, and brought greater assistance to modernization. The more common uses in engineering vehicles are transportation and installation. However, based on the various complex external environments faced by engineering vehicles and the complexity of the objects being transported or installed, the current engineering vehicles often cannot achieve better transportation or installation effects, and thus delay to a certain extent. project progress.

Problems solved by technology

However, based on the various complex external environments faced by engineering vehicles and the complexity of the objects being transported or installed, the current engineering vehicles often cannot achieve better transportation or installation effects, and thus delay to a certain extent. project progress

Especially in the construction process of large concrete box culverts, due to the heavy weight of box culverts, gantry cranes or heavy cranes are often used for installation at present, but this installation method has high requirements on the site, and cranes and other equipment need to be placed in advance, and the time cost is relatively high. High, high rental costs, time-consuming and labor-intensive installation

Especially in the construction of various small tunnels such as highway culverts, urban underpass tunnels, underground cables, telecommunications, drainage, etc., it is not convenient to use large cranes, which affects construction efficiency

[0003] Moreover, when the current engineering vehicles sometimes need to pass through obstacles of a certain height, they can only pass the obstacles temporarily by padding stones and planks, and for some areas with limited heights, they can only take a detour.

This way is not only extremely inconvenient, but also the driving safety is not high

Therefore, the inventor found that the existing construction vehicles not only have low construction efficiency, but also have poor obstacle-passing ability, especially for the lack of effective construction vehicles for the transportation and installation of box culverts during the box culvert construction process.
