Description

Technical Field

[0001] The present invention belongs to the technical field of construction marking devices, and particularly relates to a design and layout device for traffic management facilities. Background Art

[0002] In the design and layout operation of traffic management facilities, it is usually necessary to pre-position the construction location before construction. The traditional positioning method uses manual marking. Although this method can meet certain construction requirements, there are problems that manual marking is prone to errors. If precise marking is desired, various tools are needed for the positioning of points, which is time-consuming and laborious. Therefore, there is still room for improvement.

[0003] A garden engineering construction layout and sizing tool disclosed in Chinese Patent CN202222152130.X can realize the marking function only by bouncing the measuring rope on the ground where marking is required, achieving an integrated operation of measurement and marking. However, when using the above device for point positioning, it is necessary to measure manually with the help of tools, which is rather inconvenient.

[0004] Therefore, how to provide a design and layout device for traffic management facilities that can accurately control and position and mark circles is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a design and layout device for traffic management facilities, which can realize circular positioning and marking, better define the construction scope, and has higher reliability.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme: A design and layout device for traffic management facilities, which includes:

[0007] An intelligent trolley, on which an installation vertical plate is arranged;

[0008] A storage box, which is a ring-shaped structure box body. The outer side wall of the storage box is fixedly connected to the installation vertical plate. There is a ring-shaped opening on the bottom wall of the storage box, and a wavy rack rail is arranged on the outer side wall of the storage box in a ring shape;

[0009] A lifting material box, which is a ring-shaped structure. The lifting material box rotates at the bottom of the storage box and is connected and communicated with the opening. Guide wheels are arranged on the outer side wall of the lifting material box. The guide wheels are slidably connected to the bottom of the wavy rack rail and drive the lifting material box to move up and down during rotation. A plurality of material leakage openings are circumferentially spaced on the bottom wall of the lifting material box;

[0010] A driving component, which is arranged on the inner side wall of the inner circle of the storage box. The output end of the driving component is in transmission connection with the inner side wall of the inner circle of the lifting material box;

[0011] Spreading mechanism, there are multiple groups of the spreading mechanism which are respectively flexibly connected and communicated below the material leakage port. An adjusting rod for adjusting the distance between them is provided between multiple spreading mechanisms. A plug rod for controlling the spreading state and capable of moving up and down is provided on the spreading mechanism, and the bottom end of the plug rod is slidably connected to the ground.

[0012] The beneficial effects of the present invention are as follows: The intelligent trolley can drive to a specified position, the powder in the storage box will enter the lifting material box, the driving component can drive the lifting material box to rotate, the guide wheels on the outer side of the lifting material box move on the undulating track, and the rotation and lifting of the lifting material box are realized under the action of the track of the undulating track. The spreading mechanism is arranged at the bottom of the lifting material box. During the downward movement of the spreading mechanism, the plug rod touches the bottom to open the material port of the spreading mechanism and output the powder. The entire spreading mechanism draws a circle during the rotation process to achieve a circular mark. Compared with the traditional dot-shaped and fork-shaped marks, the circle can better define the construction range and improve the reliability. The distance between the spreading mechanisms can be controlled in size by the adjusting rod to change the size of the circle, and the practicability is strong.
