Description

Technical Field

[0001] The utility model belongs to the technical field of road construction tools, and in particular relates to a device capable of adjusting the installation level of a curbstone and controlling a gap. Background Art

[0002] The installation of curbstones is involved in road construction projects. Curbstones are marker stones placed between the road surface and other structures. Curbstones are generally required between the dividing strip and the road surface, and between the sidewalk and the road surface of urban roads. Curbstones are often required at the edge of the central dividing strip of the highway, the right edge of the lane, or the outer edge of the shoulder. The indicators that need to be guaranteed for the installation of curbstones are usually the installation level and the gap between adjacent curbstones. The above two indicators are also important indicators for evaluating the quality of curbstone construction.

[0003] Under current circumstances, the efficiency of curbstone installation in road construction is low, and the qualified rate of one-time installation cannot meet the requirements. The above problems are caused by the inability of construction workers to quickly and accurately ensure the above installation level and adjacent gap indicators during curbstone construction. Due to the lack of suitable auxiliary tools to ensure the above indicators, construction workers can only slow down the construction pace and try to meet the construction process requirements through multiple leveling, gap adjustment, gap width measurement and other operations. This undoubtedly consumes a lot of manpower and reduces construction efficiency, and cannot fully guarantee the process indicators.

[0004] In summary, it is necessary to develop and design a new type of curb auxiliary construction device to assist workers in performing curb installation construction more efficiently and accurately. Utility Model Content

[0012] The advantages and positive effects of the utility model are:

[0013] The utility model provides a device for controlling the installation level and gap of an adjustable curbstone with a reasonable structural design. Compared with the existing auxiliary tools and operation methods, the control device in the utility model realizes intuitive control of the gap size between adjacent curbstones by setting a first vertical positioning plate and a second vertical positioning plate that are manually driven by a distance adjustment component to adjust the distance. The first vertical positioning plate and the second vertical positioning plate after distance adjustment are placed between adjacent curbstones, wherein the first vertical positioning plate directly abuts against the rear edge of the curbstone that has been installed in front, and the next curbstone is moved until its front edge abuts against the second vertical positioning plate, thereby realizing the control of the gap size between adjacent curbstones. By setting a middle platform at the top and installing a horizontal bubble tube on the middle platform, it is possible to judge and indicate whether the curbstone is installed in a horizontal posture.

[0014] The control device in the utility model serves as a special auxiliary tool in the installation and construction of curbstones, which can assist construction workers to install the curbstones more efficiently and accurately, thereby improving the construction efficiency of the curbstones and ensuring the construction quality of the curbstones.

The housing 6 encapsulates the distance adjustment component 1 inside. As shown in the figure, the housing 6 is a flat rectangular parallelepiped, composed of a top plate, front and rear side plates, and left and right side plates, and no bottom plate is provided, so the bottom of the housing 6 is open, and the window 8 is provided in the middle of the top plate of the housing 6. The internal distance adjustment component 1 is used to adjust the distance of the limiting structure that limits the gap size between adjacent curbs, that is, adjust the width, and the distance between adjacent curbs is set by adjusting and setting the aforementioned width.

[0022] In this embodiment, in order to facilitate holding and operating the control device, a handle 5 is further provided. The handle 5 is located above the window 8 and both ends of the handle 5 are fixedly connected to the top wall of the housing 6 .

[0023] A middle platform 4 is installed in the middle of the top of the distance adjustment component 1. The middle platform 4 is located in the window 8. A horizontal bubble tube 9 is provided on the middle platform 4. The horizontal bubble tube 9 is used to indicate whether the control device is currently placed horizontally. When the control device is in a horizontal posture, the bubble in the horizontal bubble tube 9 should move to the middle position.

[0024] In this embodiment, a strip groove is further provided on the middle platform 4 and the horizontal bubble tube 9 is embedded and fixed in the strip groove, so that the horizontal bubble tube 9 is installed in an embedded manner to avoid being exposed, thereby preventing the horizontal bubble tube 9 from being damaged due to collision.

[0025] See also Figure 2 and Figure 3 , we can see the structure of the distance adjustment component 1:

[0026] The pitch adjustment assembly 1 includes a base, a forward and reverse spiral screw 1-7 is installed at the bottom of the base, a first movable plate 1-6 is installed below the nut of the forward spiral part of the forward and reverse spiral screw 1-7, a second movable plate 1-8 is installed below the nut of the reverse spiral part of the forward and reverse spiral screw 1-7, a first vertical positioning plate 2 is installed at the bottom of the first movable plate 1-6, a second vertical positioning plate 3 is installed at the bottom of the second movable plate 1-8, and a driving end 7 is also installed at one end of the forward and reverse spiral screw 1-7, and the driving end 7 is penetrated by a hole located at the side of the housing 6. The forward and reverse spiral screw 1-7 can be driven to rotate in the forward or reverse direction by the driving end 7, and the spacing between the first movable plate 1-6 and the second movable plate 1-8 is increased or decreased accordingly.

[0027] In this embodiment, the base of the distance adjustment component 1 includes two front and rear beams 1-5, a first shaft seat 1-1 is fixed between the left ends of the beams 1-5, a second shaft seat 1-9 is installed between the right ends, and a forward and reverse spiral screw 1-7 is installed between the first shaft seat 1-1 and the second shaft seat 1-9.

[0029] In this embodiment, a slide rail 1-3 is installed at the bottom of the two beams 1-5, and two groups of left and right sliders 1-4 are installed on the slide rail 1-3, and the first movable plate 1-6 and the second movable plate 1-8 are fixedly connected to the two groups of sliders 1-4 respectively. By setting the slide rail 1-3 and the slider 1-4, the stability of the first movable plate 1-6 and the second movable plate 1-8 when they are moving in translation can be improved. Furthermore, in this embodiment, a limit stopper 1-2 is installed at both ends of each of the two slide rails 1-3. The function of setting the limit stopper 1-2 is to limit the end position of the outward movement of the first movable plate 1-6 and the second movable plate 1-8 to prevent over-limit movement.

[0030] Directions:

[0031] Place the curbstones one by one in the curbstone installation groove. Install the next curbstone after the previous one is in place. The installation position accuracy of the first curbstone should be ensured, and the installation posture should be level. Move the next curbstone to the rear of the previous one.

[0032] The distance between the first movable plate 1-6 and the second movable plate 1-8 is adjusted by the driving end head 7, so that the distance between the outer facades of the first movable plate 1-6 and the second movable plate 1-8 is equal to the gap width parameter between adjacent curbstones in the curbstone construction process; then the control device is placed between the top of the previous curbstone and the top of the next curbstone. At this time, the limiting structure formed by the first movable plate 1-6 and the second movable plate 1-8 is located in the gap between the curbstones, and the left bottom of the shell 6 should fall on the top surface of the previous curbstone and be in close contact with the top surface of the curbstone, while the outer facade of the first movable plate 1-6 is against On the rear end facade of the previous curbstone, the position and posture of the next curbstone are finely adjusted by manual cooperation tools until the front end facade of the next curbstone fits with the outer side facade of the second movable plate 1-8 and the top surface of the next curbstone is in close contact with the right bottom of the shell 6. At this time, it means that the next curbstone has been accurately installed (the gap width between the previous curbstone and the previous curbstone is equal to the width set by the first movable plate 1-6 and the second movable plate 1-8, and the bubble in the horizontal bubble tube 9 is located in the middle position because the tops of the front and rear curbstones are flush), and then the next curbstone can be fixed;

[0033] Afterwards, remove the control device, repeat the above steps, and install the next curbstone again.
