Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to a construction positioning system and method for a corrugated guardrail column. Background Art

[0002] Highway is a modern term for a public road where cars can travel. Cars, bicycles, rickshaws, horses and other vehicles and pedestrians can use it. In the early days, there were no restrictions on highways, most of which were simple roads. Later, different highways had different restrictions. As transportation became increasingly developed, more and more restricted highways were added, especially some highways that were exclusively for cars (some urban highways banned bicycles and motorcycles), and highways were developed, which were closed for cars throughout the entire journey. Now many roads, especially highways, need to install guardrails on both sides, among which corrugated guardrails are widely used on highways.

[0003] The edges of many roads are not standard straight lines, but many are curved. It is very difficult to locate the corrugated guardrail posts on curved sections. This is reflected in the following aspects: when locating, it is necessary to measure and locate according to the normal length of the arc where the road edge is located and the arc length between the posts to determine the distance between the post and the road edge and the spacing between adjacent posts; using the above measurement and positioning method, it is necessary to select many points for measurement, which takes a long time; when locating by normal, it is also necessary to measure the curve radius of the arc of the road edge, and then determine the normal point position. Inaccurate measurement can easily cause the cumulative deviation of the corrugated guardrail posts to be too large, resulting in inaccurate installation position of the corrugated guardrail, and even the need for rework.

[0048] Example 1

[0049] A corrugated guardrail column construction positioning system, such as Figure 1-16 As shown, it includes a positioning mechanism and an auxiliary mechanism 8. The positioning mechanism includes a central axis device 1, a chain guide device 2, a clamping device 3 and a limit plate device 4. The chain guide device 2 includes a first chain guide device and a second chain guide device with the same structure and length. The opposite ends of the first chain guide device and the second chain guide device are respectively connected to the two ends of the central axis device 1, and the other ends of the first chain guide device and the second chain guide device are respectively connected to the clamping device 3. The central axis device 1 and the first chain guide device and the second chain guide device are respectively connected with the limit plate device 4 between one end of the clamping device 3. The clamping device 3 is used to connect the column of the corrugated guardrail, and the limit plate device 4 is used to fix the position of the central axis device 1 and the chain guide device 2. The chain guide device 2 and the central axis device 1 constitute a simulation unit, and are used to characterize the path between adjacent columns at the edge of the arc-shaped road, and the path is parallel to the arc-shaped edge of the road. The simulation unit is equipped with an auxiliary mechanism. The auxiliary mechanism is used to deploy the simulation unit and determine the position of the middle point and the two end points of the simulation unit, so as to cooperate with the simulation unit to complete the positioning of the column or complete the positioning of the column alone.

[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 column, but also assist in the positioning of the installation of the corrugated plate. Before construction, it is necessary to determine the length of the simulation unit based on the pre-set distance between adjacent columns, such as by adding or subtracting the second positioning block until the length of the simulation unit matches the set length, and the auxiliary mechanism is used to place the simulation unit in the set position to avoid the inconsistency of the normal distance (vertical distance from the edge of the road) caused by manual placement, thereby improving the convenience of construction while ensuring measurement accuracy. At the same time, the auxiliary mechanism can complete the positioning of the column alone based on the mechanism of the positioning mechanism, further simplifying the column positioning process.

A first insertion rod 1-2 is vertically fixedly connected to the lower end of the first limiting rod 1-4. The first insertion rod 1-2 is used to be inserted 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 inserting rod is as follows: Figure 4 As shown, the first limiting rod is preferably a telescopic rod structure, so that the simulation unit can be limited at different distances from the road edge. At the same time, the length of the first limiting rod can also be used as a measuring ruler, such as Figure 1 As shown, it is connected to the edge of the road to measure whether the position of the first positioning block is accurate. The central axis device, as the chain link in 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.

[0062] Example 6

[0063] Based on embodiments 1, 2, 3, 4, and 5, this embodiment discloses that Figure 14-16 As shown, the auxiliary mechanism 8 includes a control box 81, universal wheels, armrests 82, guide rail mechanisms 83, and scroll wheels.

[0068] In this embodiment, modules of the same size are provided to enable the auxiliary mechanism to complete the positioning of the column alone. During the movement of the auxiliary mechanism, the laying of the simulation unit is omitted, and the positions of the first positioning screw, the second positioning screw and the column are directly positioned.
