Description

Technical Field

[0001] The invention belongs to the technical field of sidewalk paving, and in particular relates to a device for accurately positioning and controlling the flatness of sidewalk paving. Background Art

[0002] Pavement brick paving is an essential part of road engineering. Usually, the paving materials are different and the paving operators have different proficiency, which makes it difficult to ensure efficient paving and precise control of flatness.

[0003] The flatness control of sidewalk brick paving mainly includes controlling the deviation, horizontal slope and longitudinal slope of sidewalk brick paving to ensure the comfort of pedestrians. Usually, sidewalk brick paving is mainly positioned by manual wire pulling and manual steel ruler measurement. There are several shortcomings in the above methods: 1. Since the wire pulling needs to be repeatedly operated, the human error is large; 2. The steel ruler measurement method makes it difficult to control the flatness and the error is large. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a device for accurately positioning and controlling the flatness of sidewalk paving.

[0005] The technical solution adopted by the present invention is:

[0006] A device for accurately positioning and controlling the flatness of a sidewalk pavement. At least two positioning devices are arranged on both sides of the sidewalk to be paved. A longitudinal steel strand is connected between several positioning devices on the same side of the sidewalk to be paved. Moving devices are arranged on both sides of the sidewalk to be paved. A sleeve is connected to the moving device. The longitudinal steel strand passes through the sleeve. A calibration steel strand is connected between the moving devices on both sides of the sidewalk to be paved.

[0007] Fix the positioning devices on both sides, and then move the longitudinal steel strand to the required height of the paving section, and the height of the moving device and the calibration steel strand are also adjusted accordingly. Workers perform paving operations according to the calibration steel strand. After paving a row, move the moving device a determined distance from the longitudinal steel strand, and then proceed to paving the next row of bricks. The positions of the ends of the longitudinal steel strands on each positioning device of the present invention can be adjusted separately, so the present invention can ensure the accuracy of slope control and improve the paving flatness. The moving device of the present invention can be moved on the longitudinal steel strand, so that the calibration steel strand can play a calibration role in the new position after being moved, without the need to reinstall the positioning device or manually pull the wire, and the operation is simple.

[0008] As a preferred solution of the present invention, the positioning device includes a positioning base, a screw is fixed on the positioning base, the end of the longitudinal steel strand is sleeved on the screw, and the upper and lower sides of the longitudinal steel strand are provided with adjustment nuts, which are threadedly connected to the screw. The end of the longitudinal steel strand is moved to a determined position on the screw, and then the two adjustment nuts are screwed to tighten the end of the longitudinal steel strand, so that the height of the longitudinal steel strand can be accurately adjusted.

[0009] As a preferred solution of the present invention, one end of the screw rod away from the positioning base is connected with a handrail. When a section of sidewalk is paved, the handrail can be held to push the four positioning devices to the new sidewalk paving section.

[0010] As a preferred solution of the present invention, at least three universal casters are installed at the bottom of the positioning base. The positioning base contacts the ground through at least three universal casters, which ensures the stability of the positioning device on the one hand and the convenience of movement of the positioning device on the other hand.

[0011] As a preferred solution of the present invention, a brake mechanism is installed on the universal caster on the positioning base. When the positioning mechanism moves into place, the brake mechanism is stepped on to lock the universal caster.

[0012] As a preferred solution of the present invention, the mobile device includes a mobile base, a spring is connected to the mobile base, and the sleeve is fixed to the other end of the spring. The mobile base is directly set on the ground to ensure the stability of the mobile device after it moves into place. In addition, after adjusting the height of the longitudinal steel strand, the spring can be extended and retracted accordingly to ensure that the height of the calibration steel strand can be adjusted along with the longitudinal steel strand.

[0013] As a preferred solution of the present invention, at least three universal casters are installed at the bottom of the mobile base. The mobile base contacts the ground through at least three universal casters, which ensures the stability of the mobile device and the convenience of movement of the positioning device.

[0014] As a preferred solution of the present invention, a brake mechanism is installed on the universal caster on the mobile base. When the mobile mechanism moves into place, the brake mechanism is stepped on to lock the universal caster.

[0015] As a preferred solution of the present invention, a scale is connected to the longitudinal steel strand, which can be used to indicate the distance the moving device moves on the steel strand, so as to facilitate accurate adjustment of the position of the moving device after paving a row of bricks.

[0016] As a preferred solution of the present invention, transverse steel strands are connected between the positioning devices on both sides of the sidewalk to be laid. The transverse steel strands can improve the stability between the positioning devices on both sides.

[0017] The beneficial effects of the present invention are:

[0018] After the positioning device of the present invention is fixed, the longitudinal steel strand is moved to the required height of the paving section, and the height of the moving device and the calibration steel strand is adjusted accordingly. Workers perform paving operations according to the calibration steel strand. After paving a row, the moving device is moved a determined distance from the longitudinal steel strand, and then the next row of bricks is paved. The positions of the ends of the longitudinal steel strands of the present invention on each positioning device can be adjusted separately, so the present invention can ensure the accuracy of slope control and improve the paving flatness. The moving device of the present invention can be moved on the longitudinal steel strand, so that the calibration steel strand can play a calibration role in the new position after being moved, without the need to reinstall the positioning device or manually pull the wire, and the operation is simple.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figure 1 As shown, in the precise positioning control device for the flatness of sidewalk paving of this embodiment, two positioning devices 2 are arranged on both sides of the sidewalk 1 to be paved, a longitudinal steel strand 3 is connected between the two positioning devices 2 on the same side of the sidewalk 1 to be paved, a moving device 4 is arranged on both sides of the sidewalk 1 to be paved, a sleeve 5 is connected to the moving device 4, and the longitudinal steel strand 3 passes through the sleeve 5, and a calibration steel strand 6 is connected between the moving devices 4 on both sides of the sidewalk 1 to be paved.

[0026] Fix the positioning devices 2 on both sides, and then move the longitudinal steel strands 3 to the required height of the paving section, and the heights of the moving device 4 and the calibration steel strands 6 are also adjusted accordingly. Workers perform paving operations based on the calibration steel strands 6. After paving a row, move the moving device 4 a determined distance from the longitudinal steel strands 3, and then proceed to pave the next row of bricks. The positions of the ends of the longitudinal steel strands 3 on the four positioning devices 2 of the present invention can be adjusted separately, so the present invention can ensure the accuracy of slope control and improve the paving flatness. The moving device 4 of the present invention can be moved on the longitudinal steel strands 3, so that the calibration steel strands 6 can play a calibration role at the new position after being moved, without the need to reinstall the positioning device 2 or manually pull the wire, and the operation is simple.

[0027] Among them, Figure 2 As shown, the positioning device 2 includes a positioning base 21, a screw rod 22 is fixed on the positioning base 21, the end of the longitudinal steel strand 3 is sleeved on the screw rod 22, and adjusting nuts 23 are provided on the upper and lower sides of the longitudinal steel strand 3, and the adjusting nuts 23 are threadedly connected with the screw rod 22. An adjusting rod 24 is fixed on the adjusting nut 23 to facilitate the rotation of the adjusting nut 23. The end of the longitudinal steel strand 3 is moved to a determined position on the screw rod 22, and then the two adjusting nuts 23 are screwed to tighten the end of the longitudinal steel strand 3, so that the height of the longitudinal steel strand 3 can be accurately adjusted.

[0028] The end of the screw rod 22 away from the positioning base 21 is connected to a handrail 25. When a section of the sidewalk is paved, the handrail 25 can be held to push the four positioning devices 2 to the new sidewalk paving section. Four universal casters 7 are installed at the bottom of the positioning base 21. The positioning base 21 is in contact with the ground through the four universal casters 7, which on the one hand ensures the stability of the positioning device 2, and on the other hand ensures that the positioning device 2 is easy to move. A brake mechanism 71 is installed on the universal caster 7 on the positioning base 21. When the positioning mechanism moves into place, the brake mechanism 71 is stepped on to lock the universal caster 7.

[0029] Among them, Figure 3 As shown, the mobile device 4 includes a mobile base 41, a spring 42 is connected to the mobile base 41, and the sleeve 5 is fixed to the other end of the spring 42. The mobile base 41 is directly set on the ground to ensure the stability of the mobile device 4 after it moves into place. In addition, after adjusting the height of the longitudinal steel strand 3, the spring 42 can be extended and retracted accordingly to ensure that the height of the calibration steel strand 6 can be adjusted along with the longitudinal steel strand 3.

[0030] Four universal casters 7 are installed at the bottom of the mobile base 41. The mobile base 41 is in contact with the ground through the four universal casters 7, which ensures the stability of the mobile device 4 on the one hand and the convenient movement of the positioning device 2 on the other hand. The universal casters 7 on the mobile base 41 are equipped with brake mechanisms 71. When the mobile mechanism moves into place, the brake mechanism 71 is stepped on to lock the universal casters 7.

[0031] Furthermore, a scale 8 is connected to the longitudinal steel strand 3. The scale 8 can be used to indicate the distance that the moving device 4 moves on the steel strand, so as to facilitate accurate adjustment of the position of the moving device 4 after paving a row of bricks. Figure 4 As shown, the scale 8 is an attached scale 8 , and a magnetic buckle 81 is provided on the attached scale 8 , and the attached scale 8 is fixed to the steel strand through the magnetic buckle 81 .

[0032] Furthermore, transverse steel strands 9 are connected between the positioning devices 2 on both sides of the sidewalk 1 to be laid. The transverse steel strands 9 can improve the stability between the positioning devices 2 on both sides.

[0033] Working principle:

[0034] The elevation of the paving section is calculated to obtain the height of the longitudinal steel strand 3 on the screw rod 22 of the four positioning devices 2. Hold the hand wheel to move the four positioning devices 2 into place, and set two positioning devices 2 on each side of the sidewalk 1 to be paved. After the positioning device 2 is moved into place, step on the brake mechanism 71 on the universal caster 7 to lock the position of the positioning mechanism. According to the calculated height, move the end of the longitudinal steel strand 3 to the determined height position on each screw rod 22, and then lock the longitudinal steel strand 3 by adjusting the nut 23. Move the moving device 4 and accurately position the moving device 4 through the attached scale 8. After the moving device 4 is moved into place, step on the brake mechanism 71 on the universal caster 7 to lock the position of the moving mechanism. At this time, the calibration steel strand 6 can calibrate the laying position, which is convenient for workers to perform paving operations according to the calibration steel strand 6. However, after paving a row, move the moving device 4 again, position it through the attached scale 8, and then lay the next row of bricks. This cycle is repeated until the area surrounded by the four positioning devices 2 is laid.

[0035] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
