A sliding cavity for sliding the mounting block is provided in the rotating block, and an infrared ranging sensor and a limit bar are fixedly provided on the mounting block. A sliding component is provided on each of the rotating cylinders, and the sliding component includes two bending bars slidably mounted on the rotating cylinder, and each of the bending bars is fixedly connected to a limit block.

[0006] As a preferred solution, the cross section of each of the limit strips is L-shaped, and an opening for connecting to the limit block is formed at the upper end of the limit strip.

[0007] As a preferred solution, a rectangular cavity is provided in each rotating cylinder, and sliding openings for the sliding of the bending strip are provided on the inner walls on both sides of the rectangular cavity, a rectangular rod is slidably connected in the rectangular cavity, a second spring is fixedly connected to the inner wall on one side of the rectangular cavity, the second spring is fixedly connected to the rectangular rod, and each bending strip is fixedly connected to the corresponding rectangular rod.

[0008] As a preferred solution, a hydraulic cylinder is fixedly connected to the support seat, and a fixed block is fixedly connected to the driving end of the hydraulic cylinder. The cross-section of the fixed block is T-shaped, and two sliding grooves are provided on the fixed block. A convex block is slidably connected inside each of the sliding grooves, and a plurality of clamping grooves are provided on one side surface of the convex block, and a plurality of clamping blocks are fixedly connected to one end face of each of the rectangular rods.

[0014] The detection method of the road construction verticality detection equipment comprises the following steps: S1: Push the bottom plate to make the multiple pulleys roll until the bottom plate moves to the vicinity of the column to be detected, and wait for the two conical blocks to be stationary. At this time, the rotating block is in a horizontal state; S2: The hydraulic cylinder drives the fixed block to move toward the slider, and each slot is engaged with the matching block, and the second spring is not deformed, and the bottom plate is pushed again until the detection ball fits the surface of the column. If the two detection balls fit the surface of the column at the same time, it means that the column is vertical. If only one detection ball fits the surface of the column and the other detection ball does not contact the surface of the column, it means that the column is not vertical and has an inclination angle. S3: When it is detected that the column has an inclination angle, the hydraulic cylinder continues to drive the fixed block to move in the same direction, the second spring is deformed, the limit block is offset from the opening, and the servo motor drives the bidirectional screw to rotate. The two detection balls move along the surface of the column at the same time until the distance between the two sliders reaches the maximum. The vertical distance between the two detection balls is a known constant, and the length of the slide bar and the diameter of the detection ball are also known. Two infrared ranging sensors are used to measure the distance between the two mounting blocks and the corresponding inner wall of the sliding cavity. The difference between the two distances is the horizontal distance between the two detection balls. The horizontal distance and vertical distance between the two detection balls are known. According to the Pythagorean theorem and the angle formula of a right triangle, the inclination angle of the column can be calculated.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. After the two rotating blocks are kept horizontal under the action of gravity only, the combination of the card slot and the card block can prevent the rotating cylinder and the rotating block from rotating. At this time, the limit block is inserted into the opening to push the bottom plate until the detection ball fits the surface of the column. If the two detection balls fit the surface of the column at the same time, it means that the column is vertical. If only one detection ball fits the surface of the column and the other detection ball does not contact the surface of the column, it means that the column is not vertical and has an inclination angle. It can quickly detect whether the verticality of the column meets the standard. The operation is relatively convenient and is not easily affected by human factors. The error is greatly reduced. The error in the verticality detection of road construction is small, which is beneficial to the construction of the road. 2. When only one detection ball is in contact with the surface of the column and an inclination angle of the column is detected, the limit block is first staggered with the opening. Under the elastic force of the first spring, the other detection ball will also be in contact with the surface of the column. The servo motor drives the bidirectional screw to rotate, and the two detection balls move along the surface of the column at the same time until the distance between the two sliders reaches the maximum. The vertical distance between the two detection balls is a known fixed value, and the length of the slide bar is also known. Two infrared ranging sensors can be used to measure the distance between the two mounting blocks and the corresponding inner wall of the sliding cavity. The difference between the two distances is the horizontal distance between the two detection balls. The horizontal distance and vertical distance between the two detection balls are known. According to the Pythagorean theorem and the angle formula of the right triangle, the inclination angle of the column can be calculated, which is conducive to the subsequent adaptive adjustment of the position angle of the column to facilitate the use of the verticality detection equipment; 3. Since there may be bumps when the bottom plate moves, the blocking effect of the stabilizing sleeve can prevent the conical block from deflecting significantly, so that the conical block can quickly stop swinging. Subsequently, under the driving action of the hydraulic cylinder, the fixed block slides inside the cavity, and under the transmission action of the pull rope, the two stabilizing sleeves will move away from the conical block to prevent the stabilizing sleeves from subsequently hindering the vertical movement of the conical block, so as to facilitate the timely use of the verticality detection equipment and improve the efficiency of verticality detection.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 11 A road construction verticality detection device includes a base plate 1, a support seat 2 is fixedly connected to the base plate 1, a cavity 13 is opened in the support seat 2, and a bidirectional screw rod 14 is rotatably connected to the upper and lower inner walls of the cavity 13. Two symmetrically arranged sliders 17 are threadedly connected to the bidirectional screw rod 14, each slider 17 is slidably connected to the support seat 2, and each slider 17 is provided with a rotating assembly, which includes a rotating cylinder 21 rotatably installed on the slider 17, one end of the rotating cylinder 21 is fixedly connected to a rotating block 6, and the rotating block 6 is connected to a conical block 10 through a suspension rope 9.

[0020] A calibration component is provided on each rotating block 6, and the calibration component includes a slide rod 5 connected to the rotating block 6 through a first spring 23, and the two ends of the slide rod 5 are respectively fixedly connected to a mounting block 25 and a detection ball 4. A sliding cavity 37 for sliding of the mounting block 25 is provided in the rotating block 6, and an infrared ranging sensor 26 and a limit bar 28 are fixedly provided on the mounting block 25. A sliding component is provided on each rotating cylinder 21, and the sliding component includes two bending bars 12 slidably installed on the rotating cylinder 21, and each bending bar 12 is fixedly connected to a limit block 27.

[0021] The cross section of each limit strip 28 is L-shaped, and an opening for connecting the limit block 27 is provided at the upper end of the limit strip 28. A rectangular cavity 29 is provided in each rotating cylinder 21, and sliding openings for sliding of the bending strip 12 are provided on the inner walls on both sides of the rectangular cavity 29. A rectangular rod 22 is slidably connected in the rectangular cavity 29, and a second spring 30 is fixedly connected to the inner wall of one side of the rectangular cavity 29. The second spring 30 is fixedly connected to the rectangular rod 22. Each bending strip 12 is fixedly connected to the corresponding rectangular rod 22. A hydraulic cylinder 19 is fixedly connected to the support seat 2, and a fixed block 20 is fixedly connected to the driving end of the hydraulic cylinder 19. The cross section of the fixed block 20 is T-shaped, and two sliding grooves are provided on the fixed block 20, and a convex block 18 is slidably connected inside each sliding groove.

[0022] A plurality of slots are provided on one side surface of the convex block 18, and a plurality of blocks 31 are fixedly connected to one end surface of each rectangular rod 22. In the initial state, each limit block 27 is inserted into the corresponding opening. Under the limiting action of the limit block 27, the limit bar 28 can be prevented from sliding inside the sliding cavity 37. The hydraulic cylinder 19 drives the fixed block 20 to move toward the direction close to the slider 17. During the movement of the two convex blocks 18 along with the fixed block 20, the upper surfaces of the two L-shaped rods 32 will move along the lower surfaces of the corresponding gravity blocks 33. After each convex block 18 moves, each slot will be engaged with the matching block 31, and the second spring 30 will not be deformed.

[0023] The hydraulic cylinder 19 continues to drive the fixed block 20 to move in the same direction. At this time, each card block 31 is respectively engaged with the corresponding card slot. Under the pushing action of the convex block 18, the rectangular rod 22 and the rotating cylinder 21 will slide relative to each other, and the second spring 30 will be deformed. Under the transmission action of the rectangular rod 22, each bending strip 12 will slide relative to the rotating block 6 at the same time. After the limit block 27 moves, it will be offset from the opening on the limit strip 28. At this time, the limit block 27 cannot limit the movement of the limit strip 28.

[0024] The convex block 18 at the bottom is fixedly connected with a third spring 16, and the third spring 16 is fixedly connected to the lower inner wall of the slide groove. The two side surfaces of the convex block 18 are fixedly connected with L-shaped rods 32. The inner walls of the two sides of the support seat 2 are provided with rectangular grooves 34, and each rectangular groove 34 is slidably connected with a gravity block 33. The lower surface of the gravity block 33 is fixedly connected with a sliding frame 15, and two brake pads 36 are fixedly connected to the sliding frame 15. A plurality of pulleys 3 are rotatably installed at the bottom of the bottom plate 1. The plurality of card slots on the lower convex block 18 are respectively engaged with the corresponding card blocks 31. When the slider 17 below moves vertically downward, the convex block 18 below The block 18 will move downward at the same time, the third spring 16 will be deformed, and the two L-shaped rods 32 will move downward at the same time. In the initial state, the upper surface of each L-shaped rod 32 is in contact with the lower surface of the corresponding gravity block 33, and the upper surface of the gravity block 33 is in contact with the upper inner wall of the rectangular groove 34. After the L-shaped rod 32 moves downward, it will gradually separate from the gravity block 33. The gravity block 33 has a large mass and will move downward under the action of gravity, and drive the sliding frame 15 to move downward together until each brake pad 36 is in close contact with the corresponding pulley 3, which can effectively prevent the pulley 3 from rotating at will, so as to prevent the base plate 1 from moving at will when measuring the inclination of the column.

[0025] A rotating rod 35 is rotatably connected to the surface of one side of the support seat 2, and a rotating frame is slidably connected to the rotating rod 35. The rotating frame includes a fixedly connected support frame 7 and two stabilizing sleeves 8. Under the action of gravity, the support frame 7 and the two stabilizing sleeves 8 will be vertically arranged, and the two stabilizing sleeves 8 will be respectively sleeved on the outer sides of the two conical blocks 10. A return spring 24 is sleeved on the support frame 7, one end of the return spring 24 is fixedly connected to the support frame 7, and the other end of the return spring 24 is fixedly connected to the rotating rod 35. A pull rope 11 is fixedly connected to the support frame 7, and the pull rope 11 is fixedly connected to the fixed block 20. A through hole for the pull rope 11 to pass through is opened on the support seat 2. During the movement of the fixed block 20, the pull rope 11 will be gradually tightened, and the pull rope 11 will be pulled during the continuous movement. Under the transmission action of the pull rope 11, the support frame 7 will slide relative to the rotating rod 35, and the return spring 24 will be deformed.

[0026] The detection method of the road construction verticality detection equipment comprises the following steps: S1: Push the bottom plate 1 to make the multiple pulleys 3 roll until the bottom plate 1 moves to the vicinity of the column to be detected, and wait for the two conical blocks 10 to be in a stationary state. At this time, the rotating block 6 is in a horizontal state; S2: The hydraulic cylinder 19 drives the fixed block 20 to move toward the slider 17, and each slot is engaged with the matching block 31, and the second spring 30 is not deformed, and the bottom plate 1 is pushed again until the detection ball 4 is in contact with the surface of the column. If the two detection balls 4 are in contact with the surface of the column at the same time, it means that the column is vertical. If only one detection ball 4 is in contact with the surface of the column, and the other detection ball 4 is not in contact with the surface of the column, it means that the column is not vertical and has an inclination angle. S3: When it is detected that the column has an inclination angle, the hydraulic cylinder 19 continues to drive the fixed block 20 to move in the same direction, the second spring 30 is deformed, the limit block 27 is offset from the opening, and the servo motor drives the bidirectional screw 14 to rotate. The two detection balls 4 move along the surface of the column at the same time until the distance between the two sliders 17 reaches the maximum. The vertical distance between the two detection balls 4 is a known fixed value, and the length of the slide bar 5 and the diameter of the detection ball 4 are also known. The distance between the two mounting blocks 25 and the corresponding inner wall of the sliding cavity 37 can be measured by two infrared ranging sensors 26. The difference between the two distances is the horizontal distance between the two detection balls 4. The horizontal distance and vertical distance between the two detection balls 4 are known. According to the Pythagorean theorem and the angle formula of a right triangle, the inclination angle of the column can be calculated.

[0027] In the present invention, in the initial static state, the two stabilizing sleeves 8 are respectively located on the outside of the two conical blocks 10, and each stabilizing sleeve 8 is spaced one centimeter apart from the outer surface of the conical block 10. When in use, the base plate 1 is pushed to make the multiple pulleys 3 roll until the base plate 1 moves to the vicinity of the column to be detected, and then the pushing of the base plate 1 is stopped. Since the two ends of the inelastic suspension rope 9 are respectively fixedly connected to the rotating block 6 and the conical block 10, and the mass distribution on both sides of the rotating block 6 is uniform at this time, the rotating block 6 should be in a horizontal state under the action of gravity. Since there may be bumps when the base plate 1 moves, the conical block 10 can be prevented from being significantly deflected under the blocking effect of the stabilizing sleeve 8, so that the conical block 10 can quickly stop swinging. When the conical block 10 is stationary, the rotating block 6 is in a horizontal state.

[0028] Afterwards, the hydraulic cylinder 19 drives the fixed block 20 to move in the direction close to the slider 17. In the initial state, the two convex blocks 18 are respectively fitted with the upper and lower inner walls of the two slide grooves, and the distance between the two convex blocks 18 reaches the minimum value. At this time, the upper surfaces of the two L-shaped rods 32 are respectively fitted with the lower surfaces of the two gravity blocks 33. During the movement of the two convex blocks 18 along with the fixed block 20, the upper surfaces of the two L-shaped rods 32 will move along the lower surfaces of the corresponding gravity blocks 33. After each convex block 18 moves, multiple card slots will be respectively engaged with each card block 31, and the first The second spring 30 has not been deformed. Since the inelastic pull rope 11 is in a relaxed state in the initial state, and the two ends of the pull rope 11 are respectively fixedly connected to the support frame 7 and the fixed block 20, the fixed block 20 will gradually tighten the pull rope 11 during the movement, and pull the pull rope 11 during the continuous movement. Under the transmission action of the pull rope 11, the support frame 7 and the rotating rod 35 will slide relative to each other, the reset spring 24 will be deformed, and the two stabilizing sleeves 8 will move away from the conical block 10 to prevent the stabilizing sleeves 8 from subsequently hindering the vertical movement of the conical block 10.

[0029] In the initial state, each limit block 27 is inserted into the corresponding opening. Under the limiting effect of the limit block 27, the limit bar 28 can be prevented from sliding inside the sliding cavity 37. Under the transmission effect of the mounting block 25, the sliding rod 5 and the rotating block 6 can also be prevented from sliding relative to each other. At this time, the two detection balls 4 are located in the same vertical plane. Under the coordinated use of the clamping block 31 and the clamping groove, the rectangular rod 22 can be prevented from rotating. The side surfaces of the rectangular rod 22 are in contact with the inner walls of the rectangular cavity 29, thereby preventing the rotating cylinder 21 from deflecting. Then, the rotating cylinder 21 can be pushed again. Move the bottom plate 1 to move the support seat 2 until the detection ball 4 fits with the surface of the column. If two detection balls 4 fit with the surface of the column at the same time, it means that the column (the front view cross section of the column is a rectangular setting) is vertical. If only one detection ball 4 fits with the surface of the column and the other detection ball 4 does not contact the surface of the column, it means that the column is not vertical and has an inclination angle. The operation is relatively convenient and is not easily affected by human factors, which greatly reduces the error. The error in the verticality detection of road construction is small, which is beneficial to the construction of roads.

[0030] When it is detected that the column has an inclination angle, at this time only one detection ball 4 is in contact with the surface of the column, and the distance between the two sliders 17 is the minimum value, the hydraulic cylinder 19 continues to drive the fixed block 20 to move in the same direction, at this time each card block 31 will be engaged with the matching card slot, under the pushing action of the convex block 18, the rectangular rod 22 and the rotating cylinder 21 will slide relative to each other, the second spring 30 will be deformed, and under the transmission action of the rectangular rod 22, each bending strip 12 will slide relative to the rotating block 6 at the same time, and the limit block 27 will be staggered with the opening on the limit strip 28 after moving. At this time, the limit block 2 7 cannot limit the movement of the limit bar 28. Since the two ends of the first spring 23 are fixedly connected to the slide rod 5 and the inner wall of the sliding cavity 37 respectively, under the elastic force of the first spring 23, the other detection ball 4 will also fit with the surface of the column. The servo motor is energized, and the servo motor drives the bidirectional screw rod 14 to rotate. The two sliders 17 will move along the bidirectional screw rod 14. The two sliders 17 will slide relative to the support seat 2 at the same time, and the distance between the two sliders 17 will increase. Under the joint transmission action of the rotating cylinder 21 and the rotating block 6, the two slide rods 5 and the detection ball 4 can be driven to move at the same time.

[0031] The two detection balls 4 move along the surface of the column at the same time until the distance between the two sliders 17 reaches the maximum. At this time, the servo motor stops running, and the vertical distance between the two detection balls 4 is a known fixed value. The length of the slide bar 5 and the diameter of the detection ball 4 are also known. The distance between the two mounting blocks 25 and the corresponding inner wall of the sliding cavity 37 can be measured by two infrared ranging sensors 26. The difference between the two distances is the horizontal distance between the two detection balls 4. The horizontal distance and vertical distance between the two detection balls 4 are known. According to the Pythagorean theorem and the angle formula of the right triangle, the inclination angle of the column can be calculated, which is conducive to the subsequent adaptive adjustment of the position angle of the column to facilitate the use of the verticality detection equipment. The data of the infrared ranging sensor 26 can be transmitted to the computer, and the computer is used to quickly calculate the inclination angle.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A road construction verticality detection device according to claim 7, characterized in that: A return spring (24) is sleeved on the support frame (7), one end of the return spring (24) is fixedly connected to the support frame (7), and the other end of the return spring (24) is fixedly connected to the rotating rod (35).

9. A road construction verticality detection device according to claim 8, characterized in that: A pull rope (11) is fixedly connected to the support frame (7), the pull rope (11) and the fixed block (20) are fixedly connected, and a through hole for the pull rope (11) to pass through is provided on the support seat (2).

10. A detection method for the road construction verticality detection device according to claim 9, characterized in that: The following steps are involved: S1: Pushing the bottom plate (1) to make the multiple pulleys (3) roll until the bottom plate (1) moves to the vicinity of the column to be detected, waiting for the two conical blocks (10) to be in a stationary state, at which time the rotating block (6) is in a horizontal state; S2: The hydraulic cylinder (19) drives the fixed block (20) to move in a direction close to the slider (17), and each slot is engaged with the matching block (31), and the second spring (30) does not deform, and the bottom plate (1) is pushed again until the detection ball (4) is in contact with the surface of the column. If the two detection balls (4) are in contact with the surface of the column at the same time, it means that the column is vertical. If only one detection ball (4) is in contact with the surface of the column, and the other detection ball (4) is not in contact with the surface of the column, it means that the column is not vertical and has an inclination angle. S3: When it is detected that the column has an inclination angle, the hydraulic cylinder (19) continues to drive the fixed block (20) to move in the same direction, the second spring (30) is deformed, the limit block (27) is offset from the opening, the servo motor drives the bidirectional screw (14) to rotate, and the two detection balls (4) move along the surface of the column at the same time until the distance between the two sliders (17) reaches the maximum. The vertical distance between the two detection balls (4) is a known fixed value, the length of the slide bar (5) and the diameter of the detection ball (4) are also known, and the distance between the two mounting blocks (25) and the corresponding inner wall of the sliding cavity (37) is measured by two infrared ranging sensors (26). The difference between the two distances is the horizontal distance between the two detection balls (4). The horizontal distance and vertical distance between the two detection balls (4) are known. According to the Pythagorean theorem and the angle formula of a right triangle, the inclination angle of the column can be calculated.
