Technical Field

The invention relates to the technical field of municipal emergency equipment, in particular to a vehicle-mounted excavator.

Background

In the emergency rescue process of urban water supply and drainage, gas, heat supply, power supply buried pipelines and the like, particularly in the emergency rescue process of natural disasters, the operations of cement pavement crushing, trench excavation, sundry moving, field cleaning and the like are required.

Because the rescue site is time-tight and heavy in task, a large amount of cleaning work is needed; most of the existing excavators are crawler-type, so that the existing excavators are slow in walking speed and cannot quickly reach emergency sites; sometimes, in order to enable the excavator to quickly arrive at an emergency site, the semitrailer is used for consignment of the excavator, and a lot of inconvenience exists in the process. Continuous excavation is usually performed manually before the excavator reaches the site.

Through a great deal of practice, the applicant finds that carrying the excavator on the existing emergency rescue vehicle is a good solution for the problems. However, when the excavator is arranged on the emergency rescue vehicle and the excavating action is not needed, how to arrange the mechanical arms is to ensure that the mechanical arms do not obstruct normal driving and ensure the safety in the driving process is also a problem to be considered.

Disclosure of Invention

The invention provides a vehicle-mounted excavator, and aims to solve the problems of driving obstacles and safety after an emergency rescue vehicle carries the excavator.

A vehicle-mounted excavator comprises an emergency rescue vehicle, wherein the emergency rescue vehicle is respectively provided with a cab, a carriage and an excavating mechanism from front to back, and the excavating mechanism comprises a turntable base, a hydraulic multi-shaft movable arm fixed on the turntable base, an excavator bucket rotationally connected to the end part of the hydraulic multi-shaft movable arm and a driver seat fixed on the turntable base; the rotary table base is fixed on a fixed seat through a base rotary support, and the fixed seat is fixed on a crossbeam of the emergency rescue vehicle; the hydraulic multi-shaft movable arm is fixed on the turntable base through a large arm rotary support.

Furthermore, the hydraulic multi-shaft movable arm mainly comprises a large arm fixed on the large arm rotary support, a middle arm hinged with the large arm and a small arm hinged with the middle arm, and the bucket is hinged with the small arm; the large arm, the middle arm, the small arm and the bucket are all driven by independent oil cylinders.

Furthermore, a supporting beam is arranged below the fixing seat, and hydraulic supporting legs are fixed at two ends of the supporting beam downwards.

Furthermore, the rear wheel of the emergency rescue vehicle and the hydraulic support leg are respectively positioned on two sides of the fixed seat.

Furthermore, the excavator mechanism is equipped with a rotary oil valve, the rotary oil valve is connected with a hydraulic oil pump through a hydraulic oil pipe, and the hydraulic oil pump provides power for the excavating mechanism.

Further, the hydraulic oil pump is integrated with a vehicle engine.

Furthermore, the hydraulic oil pump adopts an independent hydraulic oil pump and is connected with a gearbox of the emergency rescue vehicle through a power takeoff.

The vehicle-mounted excavator provided by the invention can quickly reach an emergency repair site, and can timely and efficiently solve the problem of difficulty in the emergency repair site; and on the premise of not influencing the excavating angle and the excavating area, the mechanical arms are well arranged, and the balance, stability and safety of the vehicle in the running process are ensured.
