Description

Technical Field

[0001] The present application relates to the technical field of test equipment, and in particular to a convenient lane indication device for testing. Background Art

[0002] The gantry is an important transportation facility with a wide range of application value. In the future, with the continuous advancement and development of science and technology, the functions and applications of high-speed gantries will become more and more diversified and intelligent. When planning roads, sand table models are often used to calculate the input tax of urban roads. In view of the current traffic scale test bench (proportional road sand table model) lane indication system requirements, the gantry is equipped with an indicator board for driving instructions. During the sand table test, the indicator board used by the gantry to indicate road driving needs to be frequently replaced with one suitable for matching road driving according to road planning. However, the indicator board is fixed to the crossbeam of the gantry by bolts, which will reduce the overall test efficiency when the indicator board is replaced. Utility Model Content

[0031] See also Figure 1The convenient lane indication device for testing of the embodiment of the present application includes: a column 200, a beam group 100 and an indication board 400. There are two columns 200, which are used to be vertically arranged on both sides of the sand table model road. The two ends of the beam group 100 in the length direction are connected to the tops of the two columns 200, and the beam group 100 is provided with a mounting plate 300 along the driving direction of the sand table model road. The mounting plate 300 is arranged along the length direction of the beam group 100, and the mounting plate 300 is made of magnetic material. There are more than two indication boards 400, and one side of the board surface of the indication board 400 is preset with indication information, and the other side is arranged on the mounting plate 300 for magnetic connection.

[0032] In this embodiment, the columns 200 of the gantry are arranged on both sides of the sand table road, so that the crossbeam is located above the road, and the length direction of the crossbeam is perpendicular to the driving direction of the road. By conveniently replacing the indicator board 400 arranged on the crossbeam, the overall test efficiency is improved. Specifically, a mounting plate 300 is arranged on the crossbeam in the driving direction relative to the road, and the mounting plate 300 is made of a magnetic material and can be magnetically connected to the crossbeam. A magnet is arranged on the side of the indicator board 400 where no traffic information is arranged, and the indicator board 400 is magnetically connected to the mounting plate 300. In the sand table test of the road, the indicator board 400 can be directly removed from the crossbeam and replaced with an indicator board 400 that matches the road information, thereby improving the efficiency of the overall test.

[0033] It should be noted that, in real life, the information indicator board 400 on the gantry is an electronic information board, while the indicator board 400 used in the sandbox test is an information board with preset traffic symbols.

[0034] In a specific embodiment, a plurality of mounting grooves 310 are provided on the surface of the mounting plate 300 along the length direction of the beam group 100. The mounting grooves 310 match the indicator plate 400 and are used to set the indicator plate 400 inside the mounting grooves 310, thereby improving the firmness of the indicator plate 400 installed on the mounting plate 300 and preventing the indicator plate 400 from falling during the test.

[0035] In this embodiment, the installation grooves 310 are arranged at equal intervals, so that there is a distance between any two adjacent installation grooves 310, and the distance between them matches the road width of the sandbox test, so that each road of the sandbox test is matched with an indicator board 400.

[0036] According to the above embodiment, the depth of the installation groove 310 is less than the thickness of the indicator plate 400. Since the installation groove 310 matches the indicator plate 400, when the indicator plate 400 is embedded in the installation groove 310, in order to facilitate the removal and replacement, the depth of the installation groove 310 is less than the thickness of the indicator plate 400, so that the indicator plate 400 is firmly installed on the installation plate 300 and the indicator plate 400 can be easily replaced on the beam.

[0037] In a specific embodiment, the column 200 is a hollow structure, and a counterweight block is provided inside the column 200 to prevent the column 200 and the beam from tipping over while ensuring the strength of the column 200.

[0038] In a specific embodiment, the beam group 100 is a multi-section structure, including more than two beams. Magnets are provided at both ends of the beams in the length direction, and any two adjacent beams are magnetically connected to form a rectangular beam group 100. In this way, it can be used on a road consisting of multiple one-way roads, and the beams are assembled by magnetic attraction, which makes installation and disassembly more convenient.

[0039] In a specific embodiment, first fixing holes are opened at both ends of the cross beam along the length direction of the cross beam, and second fixing holes 210 are opened at the top of the column 200 along the length direction perpendicular to the column 200, and the cross-sectional diameter of the second fixing hole 210 is equal to the cross-sectional diameter of the first fixing hole. During the installation of the cross beam and the column 200, the fixing column is used to pass through the second fixing hole 210 and connect with the first fixing hole to complete the fixing of the column 200 and the cross beam.

[0040] Furthermore, fixing columns are embedded inside the second fixing hole 210 and the first fixing hole.

[0041] In a specific embodiment, the cross beam is a hollow structure to reduce the weight of the entire cross beam assembly 100 .

[0042] In a specific embodiment, the bottom of the column 200 is flat, which is convenient for placing the column 200 on both sides of the sand table road.

[0043] In a specific embodiment, the beam set 100 and the column 200 are both made of steel, which improves the service life of the gantry as a whole and facilitates magnetic fixation between beams and beams, and between beams and mounting plates 300.

[0044] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
