Description

Technical Field

[0001] This utility model relates to the field of concrete equipment technology, specifically a spraying device for concrete transport vehicles. Background Technology

[0002] Concrete is characterized by abundant raw materials, low price, and simple production process, which has led to its increasing use. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used not only in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, and other fields. Concrete is also an important material in these fields.

[0003] The existing technology has the following problems: During the production of concrete, concrete trucks are used for transportation. During this process, the sides of the concrete trucks will be contaminated by dust. In this case, spraying equipment is needed to spray and clean the sides of the concrete trucks to prevent them from becoming a source of pollution when they are driving on the road. However, there is currently a lack of a concrete truck spraying equipment that is simple in structure, easy to use, and easy to fix and move, which is not conducive to the spraying and cleaning of the sides of the concrete trucks. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying device for concrete transport vehicles, which has the characteristics of simple structure, convenient use and easy fixing and moving.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for a concrete transport vehicle, comprising a base and a telescopic support column assembly mounted on the upper end of the base. A U-shaped support frame is fixedly connected to the upper end of the support column assembly. A rotating rod is rotatably connected between the two arms of the U-shaped support frame. A U-shaped fixing frame is fixedly connected to the rotating rod. A movable cylinder is slidably connected to the U-shaped fixing frame. A push rod is fixedly connected to the side wall of the movable cylinder. An L-shaped rotating shaft is slidably connected to the push rod. The other end of the L-shaped rotating shaft passes through the U-shaped support frame and is connected to the output end of a first drive motor. The first drive motor is mounted on the side wall of the U-shaped support frame. Support frames are symmetrically fixedly connected to the upper and lower ends of the rotating rod. A spray pipe is installed at the other end of the support frame. The lower end of the spray pipe is connected to an external pressurized water supply device. Several nozzles are installed on the spray pipe.

[0006] With the above structural design, the first drive motor drives the L-shaped rotating shaft to rotate, causing the movable cylinder to reciprocate up and down on the U-shaped fixed frame. The U-shaped fixed frame drives the rotating rod to rotate, which in turn drives the spray pipe and nozzle to swing left and right, automatically adjusting the spray angle and range to cover all parts of the transport vehicle body, ensuring comprehensive dust prevention, improving spraying efficiency, and reducing the need for manual operation.

[0007] Preferably, the support column assembly includes a sleeve fixedly connected to the upper end of the base, the lower end of an extension tube extending into the sleeve, a threaded rod rotatably connected inside the sleeve, and a movable block installed at the lower end of the extension tube. The movable block is sleeved on the threaded rod and threadedly connected to the threaded rod.

[0008] With the above structural design, the support column assembly adopts a structure of sleeve and extension cylinder with threaded rod, achieving stable and precise height adjustment through threaded transmission. The extension cylinder moves up and down within the sleeve, flexibly adjusting the overall height of the spraying device according to the height of the transport vehicle, ensuring that the nozzles are always in the optimal spraying position, and avoiding spray blind spots or water waste caused by height mismatch.

[0009] Preferably, the lower end of the threaded rod is provided with a driven bevel gear, and an active bevel gear is rotatably connected to the inner side wall of the sleeve. The active bevel gear meshes with the driven bevel gear, and the active bevel gear is connected to the output end of the second drive motor, which is mounted on the outer side wall of the sleeve.

[0010] The above structural design utilizes a second drive motor to drive the active bevel gear, which in turn rotates the driven bevel gear and the threaded rod, achieving electric telescopic control. No manual adjustment is required, making operation convenient and saving manpower.

[0011] Preferably, the base has storage compartments at both ends, the lower end of the storage compartment is open and an electric actuator is installed inside the storage compartment, the output end of the electric actuator faces downward and is equipped with casters.

[0012] The above structural design incorporates storage compartments and electrically driven casters at both ends of the base. When not in use, the casters can be retracted to ensure stable installation; when relocation is needed, the casters extend for quick movement to different work locations. This design balances stability when stationary with flexibility for movement, adapting to the frequent site relocation requirements.

[0013] Preferably, the base has positioning holes.

[0014] With the above structural design, the positioning holes on the base can be connected to the foundation via bolts or other fixing devices to prevent the equipment from shifting due to vibration, wind, or water pressure during operation. This ensures equipment stability, avoids safety hazards, and improves the accuracy of spraying operations, especially in high-intensity spraying or windy environments.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This spraying device achieves multiple functions through modular design, including height adjustment, multi-angle spraying, portability, and stable positioning, effectively solving the problems of limited coverage, inconvenient adjustment, and poor mobility of traditional concrete truck spraying equipment.
