Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering equipment, in particular to a guardrail repair truck. BACKGROUND

[0002] Guardrails are indispensable safety facilities in roads and public areas. They have various forms, such as solid metal railings and simple cement guardrails. On roads, they can clearly divide lanes, prevent vehicles from changing lanes and crossing boundaries at will, and reduce the risk of traffic accidents. On bridges and riverbanks, they can prevent accidental falls and protect life safety. In public areas of parks and squares, they can separate spaces and guide pedestrian flow.

[0003] When road guardrails are severely damaged due to traffic accidents, natural disasters (such as earthquakes, floods, and strong winds), or sudden situations, they can seriously affect traffic order and increase the risk of secondary accidents. Therefore, a guardrail repair truck is needed. However, the drawbacks in the use of power of traditional guardrail repair trucks are quite prominent, which seriously restricts the efficiency and quality of repair work. Currently, many guardrail repair trucks do not have a full-power sandwich power take-off installed between the clutch and the transmission of the vehicle chassis. This deficiency leads to the need for additional installation of an engine to power the drilling frame mechanism in actual operation. The additional installation of an engine not only brings significant cost increase, from equipment procurement to subsequent maintenance, but also makes the overall structure of the vehicle complex, and the coordination between various power components poor. In the running process, the cooperation between different power sources is prone to problems, leading to smooth power transmission, and thus low work efficiency. At the same time, the guardrail repair truck does not have a cooling fan installed in front of the gear box, which makes it difficult to form an effective air path with the vehicle radiator, and the heat cannot be discharged in time and smoothly, causing the equipment to overheat during work. At the same time, the uncovered hood shell forms a ventilation duct, further weakening the cooling function of the vehicle. High temperature not only reduces the work efficiency of the equipment, but also accelerates the aging and damage of parts, shortens the service life of the equipment, increases the frequency of maintenance and replacement of parts, and brings more trouble and economic burden to the user. The drilling frame mechanism has a single mode, no double rotation and horizontal movement function, is inconvenient to adjust, the crane on the vehicle cannot be extended, the lifting capacity is weak, there is no 360-degree rotating base, and the design of the supporting legs is unreasonable, affecting the stability and space utilization of the work.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] The present application ingeniously uses the original engine of the automobile as a power source by installing a full-power sandwich power take-off between the clutch of the automobile chassis and the gearbox, without the need for additional installation of an engine to provide power for the drilling rig mechanism, which not only ensures normal driving of the automobile, but also directly provides sufficient and stable power for the drilling rig mechanism, fundamentally solving the problem of poor utilization of power of the traditional guardrail repair vehicle. In actual operation, power transmission is more smooth, and the coordination between various power components is greatly improved, effectively avoiding poor power transmission caused by different power sources, thereby greatly improving work efficiency.

In addition, a cooling fan is installed in front of the gearbox, which forms a same-direction axial wind with the automobile radiator, can quickly and effectively dissipate heat, and further optimizes the cooling air path to make heat more smoothly discharged. This improvement significantly improves the heat dissipation function of the whole vehicle, avoids the problems of reduced efficiency, accelerated aging and damage of parts caused by overheating during operation, effectively prolongs the service life of the equipment, reduces the frequency of maintenance and replacement of parts, saves a lot of time and economic cost for the user, and the drilling rig mechanism adopts a double-revolution, double-horizontal-shift mode, the revolution base is flexible and reliable, and can realize large-range horizontal shift and 360-degree rotation. This design enables the drilling rig mechanism to quickly adjust the position and angle according to the actual construction demand, greatly improving the flexibility and convenience of construction. At the same time, the drilling and piling mechanisms can be installed interchangeably, reducing the cumbersome steps of turning the equipment around, further improving the construction efficiency. In addition, the truck-mounted crane has telescopic function and can lift goods weighing up to 3 tons, and is equipped with a 360-degree rotating base and telescopic legs. When working, the telescopic legs can stabilize the vehicle to ensure construction safety, and when not working, the telescopic legs can be retracted to save space and improve the overall utilization rate of the equipment, and the convenience and efficiency of guardrail repair operations are improved in all directions, providing a strong guarantee for rapid repair of road guardrails.
