Description

Technical Field

[0001] This utility model relates to the field of road marking equipment technology, and in particular to a ground marking and line drawing device for construction engineering management. Background Technology

[0002] Some semi-automatic ground marking and line drawing devices currently on the market have certain shortcomings;

[0003] First, these devices often cannot easily adjust the width of the lines according to the user's specific needs, which causes a lot of trouble for construction workers. Second, existing devices are often not convenient enough in terms of controlling paint discharge. Moreover, the overall structure of the device is relatively complex, requiring skilled operators to achieve efficient operation. Therefore, we propose a ground marking and line drawing device for building engineering management. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a ground marking and drawing device that allows for convenient adjustment of the line width, more flexible control of paint seepage, simplified structure, and easy use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ground marking and line drawing device for construction project management includes a paint box, which is mounted on a trolley frame. The inner bottom cross-section of the paint box has a semi-circular arc structure. A line drawing structure is installed below the paint box. An opening and closing structure is provided between the paint box and the line drawing structure.

[0007] The main body of the line drawing structure is a fixed base. A material guiding control groove is provided between the fixed base and the opening and closing structure. A material guiding plate is slidably connected in the material guiding control groove. A baffle plate is provided at one end of the lower part of the material guiding plate. The baffle plate is built into an inverted trapezoidal groove that is connected to the lower part of the material guiding control groove. A line drawing roller groove that passes through the fixed base is provided below the inverted trapezoidal groove. A line drawing roller is rotatably connected in the line drawing roller groove through a rotating shaft.

[0008] The opening and closing structure includes an opening and closing roller groove, in which an opening and closing roller is rotatably connected via a rotating shaft, and a paint passage is provided along the length of the opening and closing roller to the corresponding end.

[0009] Furthermore, the top of the paint box is fitted with a lid.

[0010] Furthermore, the two wheels at the bottom of the trolley frame that are farther from the pusher end are larger than the two wheels that are closer to the pusher end. When the trolley frame is placed on the ground, the lowest point of the wheels near the pusher end, the marking roller, and the wheels far from the pusher end form an upward lifting line.

[0011] Furthermore, the top of the guide plate is provided with an inclined groove, which is inclined toward the end of the barrier plate. The guide plate and the guide control groove are slidably connected by the bottom blocking groove. The guide control groove extends away from the end of the barrier plate and opens out of the paint box. The size of the paint outlet of the guide control groove is controlled by pulling the guide plate.

[0012] Furthermore, the barrier plate is adapted to the dimensions of the inverted trapezoidal groove end face.

[0013] Furthermore, the line-marking roller protrudes from the line-marking roller groove and fits against the ground.

[0014] Furthermore, the end of the opening and closing roller away from the barrier plate is equipped with a rotating handle on the outside of the paint tank. By rotating the rotating handle, the opening and closing roller is rotated, so that the paint inlet is in a horizontal or vertical state. A ratchet and pawl locking structure is provided between the shaft of the opening and closing roller and the rotating handle.

[0015] Furthermore, the paint box, the opening and closing roller groove, the material guiding control groove, the inverted trapezoidal groove, and the marking roller groove are connected in sequence.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Convenient adjustment of line width: By sliding the guide plate in the material control trough and utilizing the design of the inclined trough and the material blocking chute, the construction personnel can easily pull the guide plate to control the paint outlet size of the material control trough. This design allows the line width to be conveniently adjusted according to the user's needs, greatly improving the flexibility and efficiency of construction.

[0018] 2. Flexible control of paint seepage: The introduction of the opening and closing structure, especially the design of the opening and closing roller and the paint inlet on it, makes the paint seepage more flexibly controllable. By turning the handle to rotate the opening and closing roller, the paint inlet can be in a horizontal or vertical state, so as to select the appropriate paint seepage method according to the construction needs.

[0019] 3. Simplified structure and convenient use: The structure of this utility model is relatively simplified, eliminating many complex and unnecessary parts, making the device lighter and easier to operate.

[0020] In summary, by conveniently adjusting the line width and flexibly controlling paint seepage, construction workers can complete ground marking and line drawing tasks more efficiently. At the same time, the simplified structure and ease of use of the device reduce the operational difficulty and error rate during construction, thereby improving the quality of construction.

[0033] Example 1

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: a ground marking and line drawing device for construction engineering management, including a paint tank 1, which is mounted on a trolley frame 2 for storing paint. The inner bottom cross-section of the paint tank 1 has a semi-circular arc structure, which facilitates the smooth flow of paint. A line drawing structure 3 is installed below the paint tank 1, and an opening and closing structure 4 is provided between the paint tank 1 and the line drawing structure 3. The line drawing structure 3 is the core part for realizing ground line drawing, and the opening and closing structure 4 is used to control the flow of paint.

[0035] The main body of the line drawing structure 3 is a fixed base 31. A guide control groove 32 is provided between the fixed base 31 and the opening and closing structure 4. The guide control groove 32 is the channel for paint to flow to the line drawing roller 37. A guide plate 33 is slidably connected in the guide control groove 32. By adjusting the position of the guide plate 33, the flow rate of paint can be controlled. A baffle plate 34 is provided at one end of the guide plate 33. The baffle plate 34 is built into an inverted trapezoidal groove 35 that is connected to the bottom of the guide control groove 32, which further controls the flow of paint. A line drawing roller groove 36 that passes through the fixed base 31 is connected to the bottom of the inverted trapezoidal groove 35. The line drawing roller 37 is rotatably connected in the line drawing roller groove 36 through a rotating shaft. The line drawing roller 37 is in direct contact with the ground and is the component that realizes the line drawing function.

[0036] The opening and closing structure 4 includes an opening and closing roller groove 41, and an opening and closing roller 42 is rotatably connected in the opening and closing roller groove 41 via a rotating shaft. A paint passage 43 is provided along the length of the opening and closing roller 42 to the corresponding end.

[0037] Example 2

[0038] like Figure 1-4 As shown, the top of the paint box 1 is fitted with a box lid 11.

[0039] The two wheels 21 at the bottom of the trolley frame 2, which are farther away from the pusher end, are larger than the two wheels 21 near the pusher end, which facilitates the movement of the device. When the trolley frame 2 is placed on the ground, the lowest point of the trolley frame 2, which is near the pusher end wheel 21, the line marking roller 37, and the lowest point of the trolley frame 2, which is far away from the pusher end wheel 21, forms an upward lifting line, ensuring proper contact between the line marking roller 37 and the ground.

[0040] The top of the guide plate 33 is provided with an inclined groove 331, which is inclined towards the end of the barrier plate 34. This design helps the paint to flow more smoothly to the line drawing roller 37 and also prevents the paint from seeping out. The guide plate 33 and the guide control groove 32 are slidably connected by the bottom blocking groove. The end of the guide control groove 32 away from the barrier plate 34 extends out of the paint box 1. The paint outlet size of the guide control groove 32 is controlled by pulling the guide plate 33, thereby adjusting the thickness of the line.

[0041] The barrier plate 34 is matched with the end face size of the inverted trapezoidal groove 35 to ensure that the barrier plate 34 can be tightly installed in the inverted trapezoidal groove 35, effectively controlling the flow of paint.

[0042] The line-painting roller 37 protrudes from the line-painting roller groove 36 and fits against the ground, ensuring that the line-painting roller 37 can evenly apply paint to the ground.

[0043] The opening and closing roller 42, located away from the barrier plate 34, is equipped with a rotating handle 421 on the outside of the paint tank 1. By rotating the rotating handle 421, the rotation of the opening and closing roller 42 can be easily controlled, so that the paint through the port 43 is in a horizontal or vertical state, thereby controlling the flow direction of the paint. A ratchet and pawl locking structure is provided between the shaft of the opening and closing roller 42 and the rotating handle 421. This design can ensure that the opening and closing roller 42 can be firmly locked after rotating to the desired position, preventing rotation during use.

[0044] Paint box 1, opening and closing roller groove 41, material guiding control groove 32, inverted trapezoidal groove 35 and marking roller groove 36 are connected in sequence.

[0045] It should be noted that when the opening and closing roller 42 switches to the horizontal state, there is still paint residue in the inverted trapezoidal groove 35 in the material guide control groove 32. Therefore, the opening and closing roller 42 needs to be rotated into the horizontal state in advance.

[0046] The working process of this utility model is as follows: When using a ground marking and line drawing device for construction engineering management, the position and direction of the trolley frame 2 are adjusted according to the ground marking requirements. Due to the design of the bottom wheel 21 of the trolley frame 2, when the trolley frame 2 is placed on the ground, its lowest point near the pusher end wheel 21, the line drawing roller 37, and the lowest point away from the pusher end wheel 21 form an upward lifting line. This helps to maintain appropriate contact pressure between the line drawing roller 37 and the ground. By turning the handle 421, the position of the opening and closing roller 42 is adjusted so that the paint inlet 43 is in a vertical state (open state), so that the paint can flow smoothly into the line drawing structure 3. The trolley frame 2 is pushed, causing the line drawing roller 37 to roll on the ground. Due to the paint box... The inner bottom cross-section of 1 has a semi-circular arc structure, allowing the paint to flow smoothly to the opening and closing structure 4. After the paint passes through the paint outlet 43 of the opening and closing roller 42, it enters the guide control groove 32. By pulling the guide plate 33, the paint outlet size of the guide control groove 32 can be adjusted, thereby controlling the thickness of the line. After the paint flows out of the guide control groove 32, it passes through the baffle plate 34 and the inverted trapezoidal groove 35, and finally reaches the line drawing roller 37. During the rolling process, the line drawing roller 37 evenly spreads the paint on the ground to form a clear marking line. After the line is drawn, the paint outlet 43 of the opening and closing roller 42 is adjusted to a horizontal state (closed state) by turning the handle 421 to prevent the paint from continuing to flow out.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
