Description

Technical Field

[0001] This utility model relates to the field of mortar leveling technology, specifically to a curbstone mortar leveling device with adjustable height and width. Background Technology

[0002] In current municipal road construction projects, a section of curb stones is often constructed first before the curb stones are installed. When installing curb stones, a mortar base needs to be laid before laying the curb stones. The curb stones are then laid on the mortar base. After the mortar dries, the curb stones can be placed stably.

[0003] Traditional methods involve manually pouring mortar onto the laid curb stones, then having workers hold leveling tools and spend long periods in a bent-over or semi-squatting position to gradually level the mortar. This results in high labor intensity for workers. During manual leveling, a thin line needs to be fixed to the top and back of the mortar, ensuring the line is at the same height. This line-hanging method is used to determine if the mortar is on a level surface. Because manual operation of the leveling tool makes it difficult to spread the mortar evenly, controlling precision is challenging. After the initial manual leveling, uneven areas require significant time to correct, making the process time-consuming. Therefore, a curb stone mortar leveling device with adjustable height and width is needed to improve the flatness and precision of the mortar and prevent worker injuries. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a curbstone mortar leveling device with adjustable height and width, which mainly solves the problems of low efficiency and poor flatness when manually leveling the curbstone mortar base, as well as the problem of labor injury to workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable height and width curbstone mortar leveling device, comprising a supporting main beam, a bottom wheel installed on the bottom surface of the supporting main beam close to the curbstone, a hollow tube fixedly connected to the side wall of the supporting main beam, a U-shaped rod passing through the hollow tube from top to bottom, a side wheel installed at the bottom of the U-shaped rod, a vertical rod passing through the hollow tube, a side wheel installed at the bottom of the vertical rod, the vertical rod and the U-shaped rod being located on opposite sides of the curbstone, an inclined beam installed at the upper end of the supporting main beam, a vertical flat steel installed on the inclined beam, and a flat plate fixedly connected to the lower end of the vertical flat steel.

[0006] With the above structural design, the U-shaped rod and vertical rod can move up and down in the hollow tube, and the height can be controlled by adjusting the limit bolts, making it suitable for various curb stones. The vertical flat steel can move up and down on the inclined beam through the second limit hole. This allows the height of the flat plate to be adjusted according to the mortar thickness required by the design, and the angle of the inclined beam can be adjusted to match the width requirements of the mortar paving, increasing the applicability of the device.

[0007] Preferably, a positioning hole is provided on the hollow tube, and a limiting bolt passes through the positioning hole to fix the hollow tube to the U-shaped rod and vertical rod passing through the hollow tube, and the side wheels at the bottom of the U-shaped rod and vertical rod are close to the curb stone.

[0008] By adopting the above structural design, the U-shaped rod and the vertical rod are tightly fixed by the limiting bolts passing through the fixing holes. The bottom side wheels of the U-shaped rod and the vertical rod are further fixed at a suitable height. When the bottom side wheels of the U-shaped rod and the vertical rod are tightly attached to the curb on both sides, the device can be further prevented from tipping over. This also enhances the robustness and stability of the device during forward operation and reduces the pushing force required by the workers.

[0009] Preferably, the supporting main beam has a U-shaped structure, and several first limiting holes are equally spaced on the two straight arms of the supporting main beam along the direction perpendicular to the length of the curb stone. The inclined beam has fixing holes that cooperate with the first limiting holes. The first positioning bolt passes through the fixing holes and the first limiting holes to fix the inclined beam to the supporting main beam.

[0010] With the above structural design, the positions of the inclined beam and the supporting main beam are fixed relative to each other by the first positioning bolt, and the leveling plate is further adjusted and fixed at a certain angle, which makes it easier to control the width of the leveling.

[0011] Preferably, the vertical flat steel has several second limiting holes evenly spaced along its length, and the inclined beam has a second fixing hole that matches the second limiting holes. The second positioning bolt passes through the second limiting holes and the second fixing hole to fix the vertical flat steel and the inclined beam. The inclined beam and the vertical flat steel are arranged in parallel.

[0012] By adopting the above structural design, the inclined beam and the vertical flat steel are fixed by the first positioning bolt, which can support the whole plate to move up and down at the bottom of the vertical flat steel. By adjusting the height of the whole plate to match the thickness of the curbstone mortar, the applicability of the device to different thicknesses of curbstone is increased.

[0013] Preferably, a handle is installed on the side wall of the supporting main beam.

[0014] The above structural design incorporates a handle to facilitate operation by pulling the device along the length of the curb, thus improving its practicality.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention utilizes a slanted beam, vertical flat steel, and a leveling plate assembly to facilitate the leveling of curbstone mortar. It is effectively applicable to curbstones of varying widths and mortar thicknesses. This device eliminates the need for manual leveling of curbstone mortar, which previously required workers to painstakingly level each section. It improves the efficiency and accuracy of mortar leveling while reducing worker fatigue. This invention can be stably and flexibly supported on already laid road curbstones, providing convenience for the leveling assembly to perform leveling treatment on the curbstone mortar.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See also Figure 1 This utility model provides a technical solution: an adjustable height and width curbstone mortar leveling device, including a supporting main beam 2. A bottom wheel 3 is installed on the lower surface of the supporting main beam 2 close to the curbstone 1. A hollow tube 16 is fixedly connected to the side wall of the supporting main beam 2. A U-shaped rod 5 passes through the hollow tube 16 from top to bottom. A side wheel 4 is installed at the bottom of the U-shaped rod 5. A vertical rod 8 passes through the hollow tube 16. A side wheel 4 is installed at the bottom of the vertical rod 8. The vertical rod 8 and the U-shaped rod 5 are located on opposite sides of the curbstone 1. A diagonal beam 9 is installed at the upper end of the supporting main beam 2. A vertical flat steel 10 is installed on the diagonal beam 9. A flat plate 11 is fixedly connected to the lower end of the vertical flat steel 10. Workers can use the U-shaped rod 5 as a handrail to provide thrust for the device's forward movement, and it also facilitates the transport of the device. The U-shaped rod 5 and the vertical rod 8 are fitted with side wheels 4 at their bottom, which are close to the side wall of the curb stone 1. The side wheels 4 and the bottom wheels 3 increase the mobility and stability of the device. The U-shaped rod 5 and the vertical rod 8 can move up and down in the hollow tube 16, and the height can be controlled by adjusting the limit bolts 6, making it suitable for various curb stones 1. The vertical flat steel 10 can move up and down on the inclined beam 9 through the second limit hole 13. This allows the height of the flat plate 11 to be adjusted according to the mortar thickness required by the design, and the angle of the inclined beam 9 can be adjusted to match the width requirements of the mortar paving, increasing the applicability of the device.

[0020] A positioning hole is provided on the hollow tube 16. A limiting bolt 6 passes through the positioning hole to fix the hollow tube 16 to the U-shaped rod 5 and the vertical rod 8 passing through the hollow tube 16. The side wheels 4 at the bottom of the U-shaped rod 5 and the vertical rod 8 are close to the curb stone 1. By firmly fixing the U-shaped rod 5 and the vertical rod 8 through the fixing hole with the limiting bolt 6, the side wheels 4 at the bottom of the U-shaped rod 5 and the vertical rod 8 are further fixed at a suitable height. When the side wheels 4 at the bottom of the U-shaped rod 5 and the vertical rod 8 are close to the curb stone 1 on both sides, it can further prevent the device from tipping over, and also enhance the firmness and stability of the device during forward operation, while reducing the pushing force of the workers.

[0021] The supporting main beam 2 has a U-shaped structure. Several first limiting holes 12 are equidistantly spaced on the two straight arms of the supporting main beam 2 along a direction perpendicular to the length of the curbstone 1. The inclined beam 9 has fixing holes that mate with the first limiting holes 12. First positioning bolts 14 pass through the fixing holes and the first limiting holes 12 to fix the inclined beam 9 to the supporting main beam 2. By fixing the positions of the inclined beam 9 and the supporting main beam 2 relative to each other using the first positioning bolts 14, the leveling plate 11 can be further adjusted and fixed at a certain angle, facilitating control of the leveling width.

[0022] The vertical flat steel 10 has several second limiting holes 13 evenly spaced along its length. The inclined beam 9 has second fixing holes that mate with the second limiting holes 13. The second positioning bolt 15 passes through the second limiting holes 13 and the second fixing holes to fix the vertical flat steel 10 and the inclined beam 9. The inclined beam 9 and the vertical flat steel 10 are arranged parallel to each other. By fixing the inclined beam 9 and the vertical flat steel 10 with the corresponding first positioning bolt 14, the entire plate 11 can be supported to move up and down at the bottom of the vertical flat steel 10. By adjusting the height of the entire plate 11 to match the thickness of the mortar of the curbstone 1, the applicability of the device to different thicknesses of the curbstone 1 is increased.

[0023] A handle 7 is installed on the side wall of the supporting main beam 2. The handle 7 makes it convenient for the operator to pull the device along the length of the curbstone 1, thus improving the practicality of the device.

[0024] Working principle: Different specifications of paving stones require different mortar base widths. The first positioning bolt 14 on the inclined beam 9 can be adjusted to fix the inclined beam 9 to the supporting main beam 2 at different angles to meet the width requirements of the paving stones. Simultaneously, considering the regional differences in mortar thickness for paving stones, the second positioning bolt 15 on the vertical flat steel 10 can be adjusted to move the flat plate 11 at the bottom of the vertical flat steel 10 up and down, achieving different mortar thicknesses. After assembling all components of the device, it is placed on the already laid curbstone 1. The worker places their hand on the handle 7 and pours the pre-mixed mortar onto the road surface. The worker applies a forward thrust to the device, allowing it to move stably and dynamically on the curbstone 1. This quickly levels the mortar on the paving stones, ensuring leveling accuracy and meeting the flatness requirements of the paving stone installation, thus improving the aesthetics of the paving stone installation.
