The technical effects that can be produced by the preferred technical scheme in the technical schemes provided by the invention are described in detail in the following.
In order to achieve the above purpose, the present invention provides the following technical scheme (fig. 2 takes cement mortar as an example):
firstly, the self-walking spraying operation vehicle 108 of the invention is driven to a proper position close to the wall surface and is away from the wall surface by a proper distance, the spraying gun 104 is connected after stopping, then power (liquid supply) is supplied to the spraying gun swinging mechanism, the spraying gun starts to do reciprocating motion in the horizontal plane, the spraying material pressurized supply machines 101, 102 and 103 are started, and the spraying material passes through the conveying pipe 106 and the spraying gun 104 and is sprayed to the wall surface by the spraying gun; and starting the lifting mechanism 2, moving the operation platform along the vertical direction, and simultaneously reciprocating the spray gun in the horizontal plane, wherein the wall surface spraying machine sprays the paint from bottom to top in a certain width range from the walking spraying operation vehicle, the scraping plate synchronously rises along with the workbench to scrape the sprayed paint on the wall surface, and a uniform spraying layer is left on the wall surface.
After spraying to a certain height, closing the spraying material pressurization supply machine, closing the distance adjusting switch, enabling the oil cylinder on the working platform to contract, enabling the spray gun to move towards the direction far away from the wall surface, starting the scissor type lifting device after the spray gun leaves the wall surface for a certain distance, enabling the working platform to descend, and completing spraying of a breadth.
Then, an operator presses down a walking switch, the storage battery supplies power to the motor, and the motor rotates and is decelerated by the speed reducer to drive the walking wheels to rotate so as to realize the movement of the vehicle body; or the motor drives the hydraulic pump to work, the hydraulic pump drives the hydraulic motor to rotate, and the hydraulic motor drives the traveling wheels to rotate, so that the vehicle body moves.
The invention is moved by a distance of one spraying width from the walking spraying operation vehicle along the direction parallel to the wall surface, the first operation is repeated, and the spraying operation of the second width is started. Thus, even spraying layers can be left on large-area wall surfaces through repeated operation.
Or the corner position with a certain distance from the roof on the wall surface can not be sprayed, after the large-area spraying is finished by the self-walking spraying operation vehicle, a worker sits in the operation fence of the self-walking spraying operation vehicle, and the machine assists the worker to finish the plastering and the plastering on the top part.
In the spraying operation process, the brick joints on the wall surface are locally sunken, and when one of the rollers connected with the contact rolls along the vertical direction and passes through the concave joint, other rollers can provide support, so that the influence of the brick joints on the spraying surface is avoided.
In the spraying operation process, the scissor type lifting mechanism lifts the workbench, the scissor fork can deviate to a certain extent, and the distance between the workbench and the wall surface can be changed.
When the distance between the fixed rack and the wall surface is reduced and exceeds a reasonable size, the contact and the movable support move inwards to a certain position to trigger the limit switch or the hydraulic switch, the limit switch or the hydraulic switch can start the oil cylinder to shrink, so that the distance between the fixed rack of the spray gun and the wall surface is increased, the distance returns to a reasonable range, the limit switch or the hydraulic switch resets, and the oil cylinder stops acting.
In a similar way, when the distance from the wall to the workbench is increased, the spring pushes the contact to move towards the direction far away from the workbench, and when the distance exceeds a reasonable range, the spring triggers the second limit switch or the hydraulic switch, the limit switch or the hydraulic switch can be started, the oil cylinder extends to ensure that the distance between the spray gun fixing rack and the wall is reduced, and the distance returns to the reasonable range, the second limit switch or the hydraulic switch resets to ensure that the oil cylinder stops acting.
Therefore, the distance dynamic adjusting system can control the distance from the wall surface to the spray gun fixing rack within a proper range; and the scraping plate moves along with the spraying plate, so that the flatness of the sprayed layer after being scraped is ensured.
