Multi-degree-of-freedom suction arm support and dredging vehicle

Abstract

The invention discloses a multi-degree-of-freedom suction arm support and a dredging vehicle. The multi-degree-of-freedom suction arm support comprises a swing mechanism, a lifting mechanism, a slip mechanism, a luffing mechanism and a suction hose, the lifting mechanism comprises lifting arm support and a suction outer pipe, slip mechanism comprises a slip rod and a suction inner pipe, the slip mechanism is in transmission connection with the luffing mechanism through the slip rod, the outer suction pipe sleeves the inner suction pipe, a discharge port of the swing mechanism communicates with an anti-overflow sealing mechanism, and the swing mechanism, the lifting mechanism, the slip mechanism and the luffing mechanism are in pipeline connection through the suction hose. When the dredging vehicle performs suction operation, multi-degree-of-freedom, multi-angle and multi-direction suction can be achieved, meanwhile, a suction pipeline is accurately and effectively controlled so as to perform suction, transfer and other work, and in the transportation process, the anti-overflow sealing mechanism can be used for sealing the feeding port of a tank body, so that secondary pollution caused by sewage and peculiar smell gas overflowing through the suction hose is prevented.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom suction boom and a dredging vehicle, belonging to the technical field of municipal environmental sanitation machinery. Background technique [0002] With the development of cities and towns and the expansion of roads in our country, the demand for dredging and maintenance of urban underground pipe networks is increasing, so the demand for mobile sewer dredging and cleaning vehicles is increasing. The sewer dredging and cleaning vehicle uses high-pressure water jets to directly impact the sludge, accumulated sand, and consolidated waste in the urban underground pipe network, or crushes tree roots, cement, and pipe wall attachments through the front-end rotating nozzle, and then reuses them. The principle of vacuum pneumatic conveying is a kind of equipment that carries out suction operation and conveys materials to the tank for transfer. [0003] At present, the suction booms of sewer dredging and clea...

AI Technical Summary

Problems solved by technology

During the operation, the simple fixed boom has single action and function, low work efficiency, high labor cost, and cannot meet the needs of most working conditions; although the rotating telescopic boom has the functions of lifting and turning, but because the suction pipeline is The suspension of the hose is not fixed, the hose will swing, and multiple people are still required to coordinate the operation, and the weight of the suction pipe is heavy, which increases the work intensity of the suction. In certain urban working conditions with limited space , the rotating telescopic boom cannot accurately and effectively control the multi-angle and multi-directional suction operations of the suction pipeline, which increases the difficulty of work, labor costs, and increases the work intensity of suction, and the work efficiency is low

[0004] In the process of completing the operation and transportation, since the position of the tank body inlet is not sealed, various sewage, odorous gases and other media in the tank body will flow out or emit through the suction hose of the suction arm during transportation. , affecting the cleanliness of municipal roads, toxic and harmful gases may even cause secondary pollution
