Description

Technical Field

[0001] This utility model relates to the field of marking device technology, and more specifically, it relates to a lime marking device for construction projects. Background Technology

[0002] A utility model patent with publication number CN214783183U discloses a lime line-laying device for road and bridge engineering. In this utility model, a lime box for storing lime is provided, and a lime-spreading pipe is provided on the side of the lime box facing the direction of vehicle movement. The lime-spreading pipe is located at the end away from the handrail on the vehicle. This means that when the worker pushes the vehicle to move, the line of sight to the lime-spreading pipe will be blocked by the lime box. If the worker's line of sight is obstructed, it will affect the accuracy of the line and may also increase the difficulty of operation. The worker needs to rely on other senses or auxiliary tools to judge the line direction of the position where the lime is discharged from the lime-spreading pipe, which will undoubtedly reduce work efficiency and increase the possibility of errors.

[0027] Please see Figure 1-3 A lime marking device for construction projects, characterized by comprising: a vehicle body assembly 1, including a vehicle platform 101, moving wheels 102, and a handrail 103, wherein the vehicle platform 101 and the moving wheels 102 are connected, and the handrail 103 is disposed on the vehicle platform 101; a lime discharge assembly 2, including a storage assembly 201 and an extension pipe 202, wherein the bottom end of the extension pipe 202 extends toward the handrail 103 of the vehicle body assembly 1, and the bottom end of the extension pipe 202 is provided with a lime discharge nozzle 203, the bottom end of which extends beyond the range of the vehicle platform 101; the lime discharge assembly 2 is connected to the vehicle platform 101. The storage assembly 201 includes a lime hopper 2011 and a support frame 2012, wherein the support frame 2012 is disposed on the vehicle platform 101, the lime hopper 2011 is mounted on the support frame 2012, and the bottom end of the lime hopper 2011 is provided with a lime discharge pipe 2013, which is connected to the extension pipe 202. The vehicle platform 101 is provided with an observation slot 104, and the ash discharge nozzle 203 is located in the observation slot 104. The vehicle platform 101 is also provided with a receiving frame 204, and the extension pipe 202 is installed on the vehicle platform 101 through the receiving frame 204.

[0028] In this embodiment, when in use, the lime for marking is placed in the lime hopper 2011 beforehand. The worker pushes the handrail 103 to move the vehicle body assembly 1 forward. During the movement, the lime in the lime hopper 2011 enters the extension pipe 202 connected below along the lime outlet pipe 2013, and finally falls to the ground below along the lime outlet nozzle 203. The lime outlet nozzle 203 is located between the handrail 103 and the lime hopper 2011, and the lime outlet nozzle 203 extends out of the vehicle plate 101 and is located in the observation slot 104, which makes it easy for the worker to directly observe the position of the lime outlet nozzle 203, thereby making it easier for the worker to judge the lime outlet position and the marking position, greatly reducing the difficulty of the worker's operation.

[0029] Please see Figure 1-3As one embodiment of the anti-tipping component 3: the vehicle platform 101 is also provided with the anti-tipping component 3. The anti-tipping component 3 includes a first mounting bracket 301, a second mounting bracket 302, and a support wheel 303. The second mounting bracket 302 is connected to the first mounting bracket 301. The support wheel 303 is installed at the end of the second mounting bracket 302 away from the first mounting bracket 301. The first mounting bracket 301 is installed on the side of the vehicle platform 101 away from the handrail 103. The angle between the connecting surface of the second mounting bracket 302 and the support wheel 303 and the lower surface of the vehicle platform 101 is 10°-50°.

[0030] More specifically, the storage component 201 is placed on the side of the vehicle platform 101 closer to the direction of travel of the vehicle body component 1, causing the center of gravity of the whole to be biased towards the direction of travel of the vehicle body component 1. When an obstacle appears in front, the vehicle body component 1 is very likely to tilt forward or even fall over. When it falls over, the vehicle body component 1 tilts forward around the first moving wheel in the direction of travel, causing the first mounting bracket 301 and the second mounting bracket 302 to tilt forward together until the support wheel 303 supports the ground, thereby preventing the vehicle body component 1 from continuing to tilt forward and effectively preventing the white ash in the ash hopper 2011 from spilling out from the top of the ash hopper 2011 when the vehicle body component 1 tilts over.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
