Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a turning angle measuring device for highway planning. Background Art

[0002] Road planning means that before construction, designers prepare advance solutions to possible problems that may occur during the construction and design processes in accordance with the design tasks and requirements, and cooperate with each other during the construction process to facilitate the smooth progress of construction.

[0003] The utility model patent with announcement number CN218847106U proposes a turning angle measuring device for road planning, including an I-shaped frame, a scale line, and a road line. The inner cavity of the I-shaped frame is movably connected with a fixing nail, one side of the inner cavity of the I-shaped frame is movably connected with a long rod, a limiting groove is provided on the top of the long rod, and the inner cavity on one side of the top of the I-shaped frame is threadedly connected with a threaded rod.

[0004] The above-mentioned turning angle measuring device for highway planning, through the coordination between structures such as the I-frame, the long pole, the bonding plate and the pointer, makes the device convenient for measuring the angle of the road bend in an arc shape. However, when the road bends too sharply and the angle is too large, after the I-frame is bonded to the road line, it is difficult to bond the bonding plate to the road line, resulting in reduced applicability. Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the problem of an existing turning angle measuring device for highway planning. Through the cooperation between structures such as an I-shaped frame, a long rod, a bonding plate and a pointer, the device has the function of facilitating angle measurement when the road bends are in an arc shape. However, when the road bends too sharply and the angle is too large, after the I-shaped frame is bonded to the road line, it is difficult to bond the bonding plate to the road line, resulting in reduced applicability.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A turning angle measuring device for highway planning comprises a fixed plate, one end of which is fixedly connected to a first bonding plate, a measuring assembly is arranged on the fixed plate, the measuring assembly comprises a fixed column fixedly connected to the upper surface of the fixed plate away from one end of the first bonding plate, a rotating block is sleeved on the fixed column, a side wall of one side of the rotating block is fixedly connected to a second bonding plate via a telescopic assembly, a scale is engraved on the upper surface of the rotating block, and a pointer is fixedly connected to the top of the fixed column via a connecting piece.

[0008] By adopting the above technical solution, when in use, first the first bonding plate is bonded to the road line, and then the rotating block is rotated on the fixed column according to the angle of the road curve, and at the same time the second bonding plate is moved away from the rotating block by the telescopic component, so that the second bonding plate is bonded to the road line at another angle, and at the same time the rotation of the rotating block will drive the scale to rotate, and the turning angle can be measured according to the position of the pointer on the scale, so as to avoid as much as possible the problem that when the road curve is too sharp and the angle is too large, after the I-shaped frame is bonded to the road line, it is difficult to bond the bonding plate to the road line, resulting in reduced applicability.

[0009] Optionally, the telescopic assembly includes a fixed tube fixedly connected to a side wall of the rotating block, an end of the fixed tube away from the rotating block is slidably connected to a fixed rod, and an end of the fixed rod away from the fixed tube is fixedly connected to the second bonding plate.

[0010] By adopting the above technical solution, the distance between the second bonding plate and the rotating block can be adjusted by sliding the fixing rod in the fixing tube, so that the second bonding plate can be bonded to the road line to prevent the distance between the two road lines at the turning angle from being too far, which makes it impossible for the second bonding plate to be bonded.

[0011] Optionally, the connecting member includes a slot opened at the top of the fixed column, a limit plate is provided at the top of the fixed column, an insert block is fixedly connected to the lower surface of the limit plate, the insert block is plugged into the slot, and the pointer is fixedly connected to one side of the limit plate and is located directly above the scale.

[0012] By adopting the above technical solution, the rotating block can be disassembled from the fixed column by pulling the insert block out of the slot and removing the limit plate, so as to facilitate storage and carrying.

[0013] Optionally, a fixing bolt is provided at the top of the limiting plate, and an output end of the fixing bolt passes through the limiting plate and the insert block and is threadedly connected to the bottom wall of the slot.

[0014] By adopting the above technical solution, the limit plate can be threadedly connected to the fixing column through the fixing bolts, thereby improving the connection stability between the insert block and the slot.

[0015] Optionally, a plurality of groups of fixing holes are provided on the upper surface of the fixing plate, and fixing nails are provided in one group of the fixing holes.

[0016] By adopting the above technical solution, the ground on both sides of the road is complex, and different fixing holes can be selected to drive the fixing nails into the ground in different areas according to the ground conditions, which is convenient for fixing.

[0017] Optionally, an electric telescopic rod is fixedly connected to the lower surface of the fixed plate directly below the rotating block, and an end of the electric telescopic rod away from the fixed plate is fixedly connected to a support seat.

[0018] By adopting the above technical solution, the ground on both sides of the road is complex. When the ground height is lower than the road, the support base is fixed on the ground. The fixed plate can be raised by starting the electric telescopic rod to prevent it from being lower than the road level, making it difficult to fit the first bonding plate and the second bonding plate to the road line.

[0019] Optionally, auxiliary measurement plates are provided in both the first bonding plate and the second bonding plate, and bottom ends of the auxiliary measurement plates penetrate through the first bonding plate and the second bonding plate respectively to form a sliding connection.

[0020] By adopting the above technical solution, when the ground height is higher than the road, the first bonding plate and the second bonding plate will be located above the road line. By sliding the auxiliary measuring plate out, the auxiliary measuring plate will be bonded to the road line to prevent inaccurate measurement results.

[0021] Optionally, a transparent cover is detachably connected to the upper surface of the rotating block, and the scale and the limit plate are both located inside the transparent cover.

[0022] By adopting the above technical solution, the scale can be protected by the transparent cover to prevent dust and stains from contaminating the scale during use or storage, thereby preventing the scale from being blurred and difficult to view accurately.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] 1. The present application is provided with coordination between structures such as a fixed column, a rotating block and a telescopic assembly. When in use, the first bonding plate is first bonded to the road line, and then the rotating block is rotated on the fixed column according to the angle of the road curve. At the same time, the second bonding plate is moved away from the rotating block by the telescopic assembly, so that the second bonding plate is bonded to the road line at another angle. At the same time, the rotation of the rotating block drives the scale to rotate, and the turning angle can be measured according to the position of the pointer on the scale. This avoids the problem that when the road curve is too sharp and the angle is too large, it is difficult to bond the bonding plate to the road line after bonding the work frame to the road line, resulting in reduced applicability.

[0025] 2. Fix the support base on the ground. Start the electric telescopic rod to raise the fixing plate to prevent it from being lower than the road level, making it difficult to fit the first bonding plate and the second bonding plate to the road line. Slide the auxiliary measuring plate out to fit the auxiliary measuring plate to the road line to prevent inaccurate measurement results. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] When in use, first fit the first bonding plate 2 with the road line, and then rotate the rotating block 4 on the fixed column 3 according to the angle of the road curve, and at the same time, move the second bonding plate 5 away from the rotating block 4 through the telescopic component, so that the second bonding plate 5 is fit with the road line at another angle. At the same time, the rotation of the rotating block 4 will drive the scale 6 to rotate, and the turning angle can be measured according to the position of the pointer 7 on the scale 6, so as to avoid the problem that when the road curve is too sharp or the angle is too large, after the I-shaped frame is fitted with the road line, it is difficult to fit the bonding plate with the road line, resulting in reduced applicability.

[0033] Reference Figure 1 The telescopic assembly includes a fixed tube 8 fixedly connected to a side wall of one side of the rotating block 4, and an end of the fixed tube 8 away from the rotating block 4 is slidably connected to a fixed rod 9, and an end of the fixed rod 9 away from the fixed tube 8 is fixedly connected to the second bonding plate 5. By sliding the fixed rod 9 in the fixed tube 8, the distance between the second bonding plate 5 and the rotating block 4 can be adjusted, and the second bonding plate 5 can be bonded to the road line to prevent the distance between the two road lines at the turning angle from being too far, so that the second bonding plate 5 cannot be bonded.

[0034] Reference Figure 2 and Figure 3 The connecting part includes a slot 10 opened at the top of the fixed column 3, a limit plate 11 is provided at the top of the fixed column 3, an insert block 12 is fixedly connected to the lower surface of the limit plate 11, the insert block 12 is plugged into the slot 10, the pointer 7 is fixedly connected to one side of the limit plate 11 and is located directly above the scale 6. By pulling the insert block 12 out of the slot 10 and removing the limit plate 11, the rotating block 4 can be removed from the fixed column 3 for easy storage and carrying.

[0035] Reference Figure 3 A fixing bolt 13 is provided at the top of the limit plate 11, and the output end of the fixing bolt 13 passes through the limit plate 11 and the plug block 12 and is threadedly connected to the bottom wall of the slot 10. The limit plate 11 can be threadedly connected to the fixing column 3 through the fixing bolt 13, thereby improving the connection stability between the plug block 12 and the slot 10.

[0036] Reference Figure 1 A plurality of fixing holes 14 are provided on the upper surface of the fixing plate 1, wherein fixing nails 15 are arranged in one group of fixing holes 14. The ground on both sides of the road is complex, and the fixing nails 15 can be driven into different areas of the ground by selecting different fixing holes 14 according to the ground conditions, so as to facilitate fixing.

[0037] Reference Figure 1 The lower surface of the fixed plate 1 is located just below the rotating block 4 and is fixedly connected to an electric telescopic rod 16. The end of the electric telescopic rod 16 away from the fixed plate 1 is fixedly connected to a support seat 17. The ground on both sides of the road is complicated. When the ground height is lower than the road, the support seat 17 is fixed to the ground. By starting the electric telescopic rod 16, the fixed plate 1 can be raised to prevent it from being lower than the road level, making it difficult to fit the first bonding plate 2 and the second bonding plate 5 to the road line.

[0038] Reference Figure 1 Auxiliary measuring plates 18 are provided in the first bonding plate 2 and the second bonding plate 5. The bottom ends of the auxiliary measuring plates 18 penetrate the first bonding plate 2 and the second bonding plate 5 respectively and form a sliding connection. When the ground height is higher than the road, the first bonding plate 2 and the second bonding plate 5 will be located above the road line. By sliding the auxiliary measuring plate 18 out, the auxiliary measuring plate 18 is bonded to the road line to prevent inaccurate measurement results.

[0039] Reference Figure 1 and Figure 2 A transparent cover 19 is detachably connected to the upper surface of the rotating block 4, and the scale 6 and the limit plate 11 are both located in the transparent cover 19. The transparent cover 19 can protect the scale 6 to prevent dust and stains from contaminating the scale 6 during use or storage, causing the scale 6 to be blurred and difficult to view accurately.

[0040] The implementation principle of the present application is: when in use, first fit the first bonding plate 2 to the road line, and then rotate the rotating block 4 on the fixed column 3 according to the angle of the road curve, and at the same time, move the second bonding plate 5 away from the rotating block 4 through the telescopic component, so that the second bonding plate 5 is fit to the road line at another angle. At the same time, the rotation of the rotating block 4 will drive the scale 6 to rotate, and the turning angle can be measured according to the position of the pointer 7 on the scale 6. This avoids the problem that when the road curve is too sharp and the angle is too large, it is difficult to fit the bonding plate to the road line after the I-shaped frame is fitted to the road line, resulting in reduced applicability.
