Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road construction, in particular to a wave-shaped guardrail post construction positioning system and method. BACKGROUND

[0002] Highway is a modern term, which is a public road that can drive cars, cars, bicycles, rickshaws, horses and many other vehicles and pedestrians can walk. The early highway has no restrictions, mostly simple roads, and later different highways have different restrictions; as traffic develops, more and more highways are restricted for use, especially some highways are exclusively for cars (some city highways from banning bicycles to banning motorcycles), and the development of expressways, which are exclusively for cars. The type is full-closed for use. Now many highways, especially expressways, need to install guardrails on both sides, among which wave-shaped guardrails are widely used on expressways.

[0003] Many highway edges are not all standard straight lines, and many are arc-shaped. It is very difficult to position the wave-shaped guardrail posts on the arc-shaped road section, which is reflected in the following aspects: when positioning, the distance between the post and the highway edge and the spacing between adjacent posts need to be determined by measuring and positioning according to the normal length of the arc line where the highway edge is located and the arc length between the posts; using the above measurement and positioning method, many points need to be selected for measurement, which takes a long time; when normal point positioning, the curve radius of the highway edge arc line also needs to be measured to determine the normal point position, and inaccurate measurement can cause large cumulative deviation of the wave-shaped guardrail post, resulting in inaccurate wave-shaped guardrail installation position, and even the need for rework. SUMMARY

[0004] The present application provides a wave-shaped guardrail post construction positioning system and method, which aims to solve the problems of difficult positioning of wave-shaped guardrail posts on highway arc road sections, complicated operation, and easy cumulative error.

[0005] To solve the above problems, the technical scheme of the present application is as follows:

[0006] A wave-shaped guardrail post construction positioning system includes a positioning mechanism and an auxiliary mechanism. The positioning mechanism includes a central axis device, a guide chain device, a clamping device, and a limiting plate device. The guide chain device includes a first guide chain device and a second guide chain device with the same structure and length. The opposite ends of the first and second guide chain devices are respectively connected to the two ends of the central axis device. The other ends of the first and second guide chain devices are respectively connected to the clamping devices. The central axis device and the ends of the first and second guide chain devices near the clamping devices are respectively connected to the limiting plate devices. The clamping devices are used to connect the posts of the wave-shaped guardrail. The limiting plate devices are used to fix the positions of the central axis device and the guide chain device. The guide chain device and the central axis device constitute a simulation unit and are used to represent the path between adjacent posts on the edge of the curved highway. The path is parallel to the curved edge of the highway. The simulation unit is equipped with an auxiliary mechanism. The auxiliary mechanism is used to place the simulation unit and determine the positions of the middle point and the two end points of the simulation unit, thereby cooperating with the simulation unit to complete the positioning of the post or completing the positioning of the post independently.

[0007] Preferably, the central axis device includes a first positioning block, with through slots at its first and last ends, and through first connecting holes on the upper and lower walls of the through slots. A screw hole is provided at the top center of the first positioning block and a first positioning screw arranged longitudinally is screwed to it. The first positioning screw is used to characterize the midpoint of the simulation unit.

[0008] Preferably, the side wall surface of the first positioning block is further provided with a first threaded hole, and a first limiting rod is screwed into the first threaded hole. The first limiting rod is used to limit the distance from the first positioning screw to the edge of the road. A first insert rod is vertically fixed to the lower end of the first limiting rod. The first insert rod is used to insert into the soil outside the road and fix the first positioning block.

[0009] Preferably, the guide chain device includes several second positioning blocks that are hinged together end to end. The front end of each second positioning block has a first protrusion and the rear end has a transverse groove. The first protrusion has a second connecting hole along the longitudinal direction.

The front end of the third positioning block has a second protrusion with the same shape and size as the first protrusion, and the rear end has a threaded groove. The second protrusion is inserted into the adjacent transverse groove and hinged through the second connecting shaft. The upper end of the second connecting shaft extends upward to form a second positioning screw. The two second positioning screws are used to characterize the two end positions of the simulation unit.

[0010] Preferably, a second threaded hole is provided on the side wall of the third positioning block, and a second limiting rod is screwed into the second threaded hole. The second limiting rod is used to limit the distance from the second positioning screw to the edge of the road. A second insert rod is vertically fixed to the lower end of the second limiting rod. The second insert rod is used to insert into the soil outside the road and fix the third positioning block.

[0011] Preferably, the clamping device includes a limiting frame and a stud. The shape of the limiting frame matches the shape of the outer wall of the column and is used to clamp onto the outer wall of the column. The outer end of the limiting frame is fixedly connected to the stud, and the stud is screwed into the threaded groove.

[0012] Preferably, the limiting plate device is a first limiting plate or a second limiting plate. The opposite ends of the first limiting plate and the second limiting plate are provided with mutually cooperating openings. The openings are provided with opposite fourth connecting holes. The two fourth connecting holes are connected in series on the first positioning screw and are limited by nuts. The side of the first limiting plate and the second limiting plate away from the fourth connecting holes is also provided with a strip hole. The second positioning screw passes through the strip hole and is locked by nuts.

[0013] Preferably, the auxiliary mechanism includes a control box, casters, handrails, guide rail mechanism, and horizontal rollers. The control box has a handrail on the top rear side and casters on the bottom. One side of the control box has a guide rail mechanism for the simulation unit to pass through, and the other side has horizontal rollers. The control box contains a power module and a controller that are electrically connected to each other.

[0014] Preferably, the guide rail mechanism includes two fixed plates that are vertically opposite each other and fixedly connected to the side wall of the control box. Multiple longitudinally arranged rollers are provided on both sides of the opposite ends of the two fixed plates. Sliding grooves are respectively formed on the inner surfaces of the two fixed plates between the two sets of rollers. The rollers are used to roll in cooperation with the side wall of the simulation unit, and the sliding grooves are used to slide in connection with the two ends of the first and third hinge shafts. The transverse rollers include transverse rollers for contacting the outer wall of the road edge curb. A telescopic mechanism is connected to the top of the transverse rollers. The telescopic mechanism is connected to the side wall of the control box. The transverse rollers have two sets, front and rear. The telescopic mechanism is an electric cylinder. An electric cylinder fixing hole is provided in the control box. The fixed end of the electric cylinder is fixedly connected to the fixing hole. The telescopic end extends horizontally outward along the direction perpendicular to the direction of travel of the simulation unit within the guide rail mechanism and is connected to the top of the transverse roller. An infrared light emitter is also fixedly connected longitudinally to the side wall of the telescopic end.

[0015] Preferably, a displacement sensor is installed on the auxiliary mechanism, and a display is installed on the handrail.

The inner end of the fourth positioning block is fixedly connected to the front or rear end of the fixed plate via a third protrusion. A through hole is provided on the third protrusion for marking the position of the second positioning screw.

[0016] A method for using a corrugated guardrail post construction positioning system includes Mode 1 and Mode 2. Mode 1 includes the following steps:

[0017] (11) Without installing the third positioning block, one end of the simulation unit is input into the guide rail mechanism, and then the end of the simulation unit passing through the guide rail mechanism is connected to the third positioning block and the clamping device is connected. The clamping device clamps the first column that has been fixed, and then the second limiting rod and the second insertion rod are installed. The second insertion rod is inserted into the soil.

[0018] (12) Adjust the length of the electric cylinder according to the pre-set distance between the simulation unit and the outer wall of the curbstone, push the auxiliary mechanism forward so that the transverse roller is always in contact with the outer wall of the curbstone, the simulation unit slides along the guide rail mechanism, and after the first positioning block passes through the guide rail mechanism, install the first positioning screw at the screw hole, then install the first limit rod and the first insertion rod, and insert the first insertion rod into the soil.

[0019] (13) The auxiliary mechanism continues to move to the end of the guide chain device away from the first column, and determines the position of the second hinge shaft relative to the ground. After the auxiliary mechanism is completely separated from the simulation unit, the third positioning block is connected by installing the second hinge shaft and the clamping device is connected. Then the second limit rod is installed and the corresponding second insertion rod is inserted into the soil. At this time, the position of the limit frame on the side away from the first column is the position of the second column.

[0020] (14) Install the first limiting plate and the second limiting plate respectively, and fully insert the first and second rods into the soil to install the second column;

[0021] (15) After the second column is installed, repeat the above steps (11)-(14) starting from the second column, and repeat this cycle to complete the positioning and installation of all columns.

[0022] Mode 2 includes the following steps:

[0023] (21) The auxiliary mechanism is in the starting position. The clamping mechanism on the rear side clamps the first column that has been installed and fixed. Adjust the length of the electric cylinder so that the horizontal roller contacts the outer wall of the curb. Turn on the controller start button and push the auxiliary mechanism forward while maintaining contact.

[0024] (22) According to the displacement information displayed on the display, when the position of the first positioning screw is reached, the auxiliary mechanism stops moving, and the position of the first positioning screw is marked according to the position of the through hole on the rear side. The auxiliary mechanism continues to move forward, and when the position of the second positioning screw on the front side is reached, the auxiliary mechanism stops moving, and the position of the second positioning screw is marked according to the position of the through hole on the front side. At this time, the position corresponding to the clamping mechanism on the front side is the installation position of the second column.

[0025] (23) After installing the second column, repeat steps (21)-(22) starting from the second column until all columns are installed.

[0026] In Mode 1 and Mode 2, if there is no curb on the side of the road, the moving auxiliary mechanism will always use the infrared light emitted by the infrared light emitter to be aimed at the edge line of the road when moving.

[0027] The present invention provides a construction positioning system and method for corrugated guardrail posts, which has the following beneficial effects:

[0028] This invention can be used for the installation and positioning of corrugated guardrail posts on straight or curved highways, solving the problems of difficult positioning, cumbersome operation, and easy accumulation of errors in corrugated guardrail posts on curved highway sections. It can significantly improve construction efficiency, ensure positioning accuracy, reduce construction difficulty, and improve construction quality. Attached Figure Description

[0048] Example 1

[0049] A wave-shaped guardrail post construction positioning system, such as Figures 1-16 As shown, the system includes a positioning mechanism and an auxiliary mechanism 8. The positioning mechanism includes a central axis device 1, a guide chain device 2, a clamping device 3, and a limiting plate device 4. The guide chain device 2 includes a first guide chain device and a second guide chain device with the same structure and length. The opposite ends of the first guide chain device and the second guide chain device are respectively connected to the two ends of the central axis device 1. The other ends of the first guide chain device and the second guide chain device are respectively connected to the clamping device 3. The limiting plate device 4 is connected between the central axis device 1 and the ends of the first guide chain device and the second guide chain device near the clamping device 3. The clamping device 3 is used to connect the posts of the corrugated guardrail. The limiting plate device 4 is used to fix the positions of the central axis device 1 and the guide chain device 2. The guide chain device 2 and the central axis device 1 constitute a simulation unit and are used to represent the path between adjacent posts on the edge of the curved highway. The path is parallel to the curved edge of the highway. The simulation unit is equipped with an auxiliary mechanism, which is used to place the simulation unit and determine the positions of the middle point and the two end points of the simulation unit, thereby cooperating with the simulation unit to complete the positioning of the posts or completing the positioning of the posts independently.

[0050] In this embodiment, after the simulation unit is positioned at the edge of the road, it can not only assist in the positioning of the posts but also in the positioning of the corrugated plate installation. Before construction, the length of the simulation unit needs to be determined according to the pre-set distance between adjacent posts, for example, by adding or removing a second positioning block until the length of the simulation unit matches the set length. The auxiliary mechanism is then used to place the simulation unit in the set position, avoiding inconsistencies in the normal distance (vertical distance from the road edge) caused by manual placement, thereby improving construction convenience while ensuring measurement accuracy. At the same time, the auxiliary mechanism can independently complete the post positioning work based on the mechanism of the positioning mechanism, further simplifying the post positioning process.

[0051] Example 2

[0052] Based on Example 1, this example discloses, as follows: Figures 2-4 As shown, the central axis device 1 includes a first positioning block 1-1. The first positioning block 1-1 has through slots 1-5 at its head and tail ends, and the upper and lower walls of the through slots 1-5 have through first connecting holes 1-6. The top center of the first positioning block 1-1 has a screw hole and a first positioning screw 1-3 arranged longitudinally is screwed to it. The first positioning screw 1-3 is used to characterize the midpoint of the simulation unit.

[0053] like Figures 1-4 As shown, the side wall surface of the first positioning block 1-1 is also provided with a first threaded hole, and a first limiting rod 1-4 is screwed into the first threaded hole. The first limiting rod 1-4 is used to limit the distance from the first positioning screw 1-3 to the edge of the road. A first insert rod 1-2 is vertically fixedly connected to the lower end of the first limiting rod 1-4. The first insert rod 1-2 is used to insert into the soil outside the road and fix the first positioning block 1-1.

[0054] In this embodiment, the positional relationship between the first limiting rod and the first insert rod is as follows: Figure 4 As shown, the first limiting rod is preferably a telescopic rod structure, which can limit the different distances between the simulation unit and the road edge. Simultaneously, the length of the first limiting rod can also be used as a measuring ruler, such as... Figure 1 As shown, connecting it to the road edge can be used to measure the accuracy of the position of the first positioning block. The central axis device, as the link at the center of the simulation unit, can locate the center point of the simulation unit. While assisting in measuring the position of the column, it can also assist in the installation and positioning of the corrugated plate.

[0055] Example 3

[0056] Based on embodiments 1 and 2, this embodiment discloses, as follows: Figure 5 , 6As shown, the guide chain device 2 includes several second positioning blocks 2-1 connected end-to-end. Each second positioning block 2-1 has a first protrusion 2-1-1 at its front end and a transverse groove 2-1-2 at its rear end. The first protrusion 2-1-1 has a second connecting hole (not marked in the figure) along its longitudinal direction. The upper and lower walls of the transverse groove 2-1-2 have through third connecting holes (not marked in the figure). The first protrusion and transverse groove between adjacent second positioning blocks 2-1 are inserted into each other and hinged by a first hinge shaft 2-3 passing through the second and third connecting holes. The outermost second positioning block 2-1 is connected... A third positioning block 2-2 is connected. The front end of the third positioning block 2-2 is provided with a second protrusion with the same shape and size as the first protrusion, and the rear end is provided with a threaded groove 2-7. The second protrusion is inserted into the adjacent transverse groove 2-7 and is hinged through the second hinge shaft 2-4. The upper end of the second hinge shaft 2-4 extends upward to form a second positioning screw. The two second positioning screws are used to characterize the two end positions of the simulation unit. The first protrusion 2-1-1 adjacent to the first positioning block 1-1 is inserted into the through groove and is hinged through the third hinge shaft (not marked in the figure) that passes through the first connecting hole and the second connecting hole.

[0057] like Figure 5 , 6 As shown, a second threaded hole is provided on the side wall of the third positioning block 2-2, and a second limiting rod 2-6 is screwed into the second threaded hole. The second limiting rod 2-6 is used to limit the distance from the second positioning screw to the edge of the road. A second insertion rod 2-5 is vertically fixedly connected to the lower end of the second limiting rod 2-6. The second insertion rod 2-5 is used to insert into the soil outside the road and fix the third positioning block 2-2.

[0058] Example 4

[0059] Based on embodiments 1, 2, and 3, this embodiment discloses, as follows: Figure 7 , 8 As shown, the clamping device 3 includes a limiting frame 3-1 and a stud 3-2. The shape of the limiting frame 3-1 matches the shape of the outer wall of the column 7 and is used to clamp onto the outer wall of the column 7. The outer end of the limiting frame 3-1 is fixedly connected to the stud 3-2, and the stud 3-2 is screwed into the threaded groove 2-7.

[0060] Example 5

[0061] Based on embodiments 1, 2, 3, and 4, this embodiment discloses, as follows: Figure 1 , 9 As shown in Figure -11, the limiting plate device 4 is either a first limiting plate 4-1 or a second limiting plate 4-2. The opposite ends of the first limiting plate 4-1 and the second limiting plate 4-2 are provided with mutually cooperating openings, and the openings are provided with a fourth connecting hole (e.g., Figure 11As shown in the figure (not marked), two fourth connecting holes are connected in series on the first positioning screw 1-3 and limited by nuts. The first limiting plate 4-1 and the second limiting plate 4-2 also have strip-shaped holes 4-4 on the side away from the fourth connecting holes. The second positioning screw passes through the strip-shaped hole and is locked by a nut. Figure 1 As shown, the strip hole facilitates the adjustment of the position of the second positioning screw when positioning different arc paths.

[0062] Example 6

[0063] Based on embodiments 1, 2, 3, 4, and 5, this embodiment discloses, as follows: Figures 14-16 As shown, the auxiliary mechanism 8 includes a control box 81, casters, handrails 82, guide rail mechanism 83, and horizontal rollers. The control box 81 has a handrail 82 on the top rear side and casters on the bottom. One side of the control box 81 has a guide rail mechanism 83 for the simulation unit to pass through, and the other side has horizontal rollers. The control box 81 contains a power module and a controller that are electrically connected to each other.

[0064] like Figures 14-16 As shown, the guide rail mechanism 83 includes two vertically opposite fixed plates 831 fixedly connected to the side wall of the control box 81. Multiple longitudinally arranged rollers 832 are provided on both sides of the opposite ends of the two fixed plates 831. Sliding grooves 834 are respectively formed on the inner surfaces of the two fixed plates 831 between the two sets of rollers 832. The rollers 832 are used for rolling cooperation with the side wall of the simulation unit, and the sliding grooves 834 are used for sliding connection with the two ends of the first hinge shaft 2-3 and the third hinge shaft. The horizontal rollers include those for contacting the outer wall of the road edge curb. The horizontal roller 85 has a telescopic mechanism connected to its top. The telescopic mechanism is connected to the side wall of the control box 81. The horizontal roller 85 has two sets, front and rear. The telescopic mechanism is an electric cylinder 84. The control box 81 has an electric cylinder fixing hole 87. The fixed end of the electric cylinder 84 is fixedly connected to the fixing hole 87. The telescopic end extends horizontally outward along the direction perpendicular to the direction in which the simulation unit travels within the guide rail mechanism 83 and is connected to the top of the horizontal roller 85. An infrared light emitter 86 is also fixedly connected longitudinally to the side wall of the telescopic end.

[0065] In this embodiment, the distance between the simulation unit and the outer wall of the curbstone can be controlled by adjusting the extension of the electric cylinder. Since the simulation unit simultaneously passes through the guide rail mechanism as the auxiliary mechanism moves along the outer side of the curbstone, the distance between the simulation unit and the outer wall of the curbstone remains consistent. This allows the simulation unit to accurately simulate the path between adjacent posts. Through simulation, the path distance between adjacent posts can be effectively controlled, as well as the spacing between the posts and the outer wall of the curbstone. Simultaneously, it provides positioning assistance for the installation of the corrugated plate. In cases where there is no curbstone, the simulation unit can be laid by emitting infrared light through an infrared emitter, ensuring that the infrared light remains aligned with the edge line of the road during the movement of the auxiliary mechanism. The edge line can be manually drawn.

[0066] Example 7

[0067] Based on Example 6, this example discloses, as follows: Figures 14-16 As shown, a displacement sensor (not shown in the figure) is installed on the auxiliary mechanism 8, and a display (not shown in the figure) is installed on the handrail 82. The displacement sensor and the display are electrically connected to the controller via wires. The front and rear ends of the upper fixing plate 831 are respectively connected to modules of the same size. The modules of the same size include a fourth positioning block 810 with the same shape and size as the third positioning block, and a clamping mechanism (first clamping mechanism 811 and second clamping mechanism 812) connected to the outer end of the fourth positioning block 810 with the same shape and size as the clamping device. The inner end of the fourth positioning block 810 is fixedly connected to the front or rear end of the fixing plate 831 through a third protrusion 89. A through hole 88 is provided on the third protrusion for marking the position of the second positioning screw.

[0068] In this embodiment, modules of the same size are set so that the auxiliary mechanism can complete the positioning of the column independently. During the movement of the auxiliary mechanism, the installation of the simulation unit is omitted, and the positions of the first positioning screw, the second positioning screw and the column are directly positioned.

[0069] Example 8

[0070] Based on the above embodiments, this embodiment discloses a method for using a corrugated guardrail post construction positioning system, including Mode 1 and Mode 2. Mode 1 includes the following steps:

[0071] (11) Without installing the third positioning block, one end of the simulation unit is input into the guide rail mechanism, and then the end of the simulation unit passing through the guide rail mechanism is connected to the third positioning block and the clamping device is connected. The first column that has been fixed is clamped by the clamping device, and then the second limit rod and the second insertion rod are installed. The second insertion rod is inserted into the soil, that is, the position of the second positioning screw is fixed here.

[0072] (12) According to the pre-set distance between the simulation unit and the outer wall of the curbstone, adjust the length of the electric cylinder 84, push the auxiliary mechanism 8 forward, so that the transverse roller 85 is always in contact with the outer wall of the curbstone 6, the simulation unit slides along the guide rail mechanism, and after the first positioning block passes through the guide rail mechanism, install the first positioning screw at the screw hole, then install the first limit rod and the first insertion rod, and insert the first insertion rod into the soil;

[0073] (13) The auxiliary mechanism 8 continues to move to the end of the guide chain device away from the first column, and determines the position of the second hinge shaft relative to the ground. After the auxiliary mechanism is completely separated from the simulation unit, the third positioning block is connected by installing the second hinge shaft and the clamping device is connected. Then the second limit rod is installed and the corresponding second insertion rod is inserted into the soil. At this time, the position of the limit frame on the side away from the first column is the position of the second column.

[0074] (14) Install the first limiting plate 41 and the second limiting plate 42 respectively, and fully insert the first and second rods into the soil to install the second column;

[0075] (15) After the second column is installed, repeat the above steps (11)-(14) starting from the second column, and repeat this cycle to complete the positioning and installation of all columns.

[0076] Mode 2 includes the following steps:

[0077] (21) The auxiliary mechanism is in the starting position. The clamping mechanism on the rear side clamps the first column that has been installed and fixed. Adjust the length of the electric cylinder so that the horizontal roller 85 contacts the outer wall of the curbstone 6. Turn on the controller start button and push the auxiliary mechanism 8 forward while maintaining contact.

[0078] (22) According to the displacement information displayed on the display, when the position of the first positioning screw is reached, the auxiliary mechanism 8 stops moving, and the position of the first positioning screw is marked according to the position of the through hole 88 on the rear side. The auxiliary mechanism continues to move forward, and when the position of the second positioning screw on the front side is reached, the auxiliary mechanism stops moving, and the position of the second positioning screw is marked according to the position of the through hole 88 on the front side.
