Problems solved by technology
[0004] However, in some special working conditions, the above-mentioned power drive forms have shortcomings: when working in high-altitude and long-distance tunnels, due to the low power transmission efficiency and the inconvenience of laying cables, the wet spraying trolley cannot perform spraying operations
In this case, it is necessary to temporarily equip a generator, which is driven by the engine to generate electricity to provide the power required for injection, which is inconvenient to use
In addition, because the injection system needs an external high-voltage power supply, the maneuverability is poor, and there are certain potential safety hazards

Embodiment Construction
[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0025] refer to figure 1 As shown, a wet spray trolley according to a preferred embodiment of the present invention includes an engine 1, a chassis, a spray mechanism and other functional components. The power output by the engine 1 can be transmitted to the running system of the chassis (such as to the wheels) through the gearbox 20 to drive the wet spray trolley forward or backward to realize the driving action. Moreover, the power output by the engine 1 can also be selected to be transmitted to the spraying mechanism through, for example, the pumping cylinder 4, so as to spray the concrete mixture to the working surface to realize the spraying operation.

The invention relates to the field of engineering machinery, and discloses a wet spraying trolley. The wet spraying trolley comprises an engine (1), a chassis which consists of a hydraulic transmission system and a running system, and an injection mechanism, wherein the injection mechanism and the running system are correspondingly selectively in transmission connection with the engine (1) throughthe hydraulic transmission system, and thus the engine (1) is capable of driving to perform running and / or injection work. According to the wet spraying trolley, the engine (1) is used for supplyingpower for running and injection work, and additional power supply is not needed, so that injection works such as lining supporting can be completed under the working condition of inconvenient power supply, and the wet spraying trolley is convenient to use and good in maneuverability; and due to that high-voltage power supply is not needed, the wet spraying trolley can effectively improve the usesafety.
Description
technical field [0001] The invention relates to engineering machinery, in particular to a wet spray trolley. Background technique [0002] Wet spraying trolley is a commonly used construction machine in engineering. It has self-propelled function and can spray wet concrete mixture onto the working surface, which is used for lining the surface of rocks, brick walls, steel structures and wooden formwork. support. [0003] In order to meet the basic functions of self-propelled and spraying operations, the wet spraying trolley is usually equipped with an engine (such as a diesel engine) and an electric motor. The chassis driving system is driven by the engine to move forward and backward, and the hydraulic transmission system is driven by the electric motor to realize the concrete spraying operation. That is, the existing wet spray trolley utilizes two sets of relatively independent power systems to realize self-propelled and spray operation functions respectively. This form o...
