Description

Technical Field

[0001] The utility model relates to the technical field of traffic gantries, in particular to an assembled gantry for road traffic. Background Art

[0002] A traffic gantry is a traffic facility used on roads. It is usually formed by processing steel pipes and its surface is treated with hot-dip galvanization. It has the characteristics of being stable, hard, wind-resistant and sun-proof. It is widely used in highways, urban roads and various roads for installing traffic signs, LED screens, information screens, etc. On some roads, gantries can also be used to install traffic management facilities such as surveillance cameras and speed measurement devices.

[0003] There is no fixed standard for the height of traffic gantries. Usually, it is set according to the actual situation of the road and usage requirements. On highways, the height of gantries is generally not less than 5500mm; on national and provincial roads, the height of gantries is not less than 5000mm. When setting gantries, it is necessary to consider the height of vehicles and traffic requirements to ensure that vehicles can pass safely. In addition, in some special cases, the height of gantries may be reduced. For example, on urban roads with a large proportion of small vehicles, the height of the lower edge of the gantry from the ground can be reduced according to the actual situation, but it should not be less than 120cm. Or in some places where vehicle height needs to be restricted, height-limiting gantries are also set up.

[0004] During the processing and production of gantries, they are generally customized according to usage requirements and their height is fixed. Thus, in the actual operation process, there are certain limitations. For example, for a height-limiting gantry with a fixed height, when transporting ultra-high objects, the gantry needs to be disassembled before object transportation, wasting manpower and materials. Based on this, an assembled gantry for road traffic is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide an assembled gantry for road traffic to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An assembled gantry for road traffic includes a column assembly and a crossbeam assembly. The column assembly consists of columns, mounting seats and first connecting seats. The crossbeam assembly consists of second connecting seats, connecting columns and crossbeams.

[0007] There are four columns. The first connecting seats and mounting seats are respectively fixed at the upper and lower ends of the four columns. There are two groups of column assemblies.

The bottom end of the steel wire rope extends below the storage box and is fixedly connected to the limiting beam. The limiting beam is distributed between the two groups of column assemblies. By driving the winding shaft to run by the driving motor, the steel wire rope is wound or unwound, so as to realize the lifting operation of the limiting beam.

[0013] As a further scheme of the present utility model: reinforcing ribs are welded and fixed between every two of the four columns, and no reinforcing ribs are arranged between the two columns that are close to each other in the two groups of column assemblies, which is used to provide space for the up and down movement of the limiting beam.

[0014] As a further scheme of the present utility model: limiting guide wheels are symmetrically installed on the side faces at both ends of the limiting beam. An annular groove is formed on the roller surface of the limiting guide wheel, and the roller of the limiting guide wheel is attached to the outer wall of the column through the annular groove.

[0015] As a further scheme of the present utility model: reinforcing plates are symmetrically fixedly connected to both ends of the limiting beam. Fixed vertical plates are arranged on the inner sides of the four columns. The fixed vertical plates are welded and fixed to the reinforcing ribs. Bolts are sequentially passed through the mounting holes on the fixed vertical plates and the reinforcing plates to realize the height reinforcement of the limiting beam.

[0016] As a further scheme of the present utility model: the height of the fixed vertical plate is greater than the height of the reinforcing plate, and the horizontal height of the bottom end of the fixed vertical plate is the lowest use height of the limiting beam.

[0018] The inner wall width and length of the storage box are respectively greater than the distribution width of the limiting guide wheels on both sides of the limiting beam and the length of the limiting beam;

[0019] The height from the bottom end of the take-up reel to the bottom end of the storage box is greater than the height of the limit beam.

[0030] The cross beam 203 is fixed to the tops of two second connecting seats 201 through connecting columns 202. The second connecting seats 201 and the first connecting seats 103 are fixedly connected by bolts, which is used to realize the assembly connection between the cross beam assembly 2 and the two column assemblies 1;

[0031] A height limiting component 3 is arranged at the bottom end of the cross beam 203, and the height limiting component 3 is used to adapt to different height limiting requirements;

[0032] The height limiting component 3 includes a storage box 301, a driving motor 302, a winding shaft 303, a steel wire rope 304 and a limiting beam 305;

[0033] The storage box 301 is welded and fixed to the bottom end of the cross beam 203. The driving motor 302 is installed at one end of the storage box 301, and the output end of the driving motor 302 penetrates to the inner side of the storage box 301 and is fixedly connected to the winding shaft 303. The other end of the winding shaft 303 is rotatably connected to the other end of the storage box 301;

[0034] The top end of the steel wire rope 304 is wound and tied and fixed to the outer side of the winding shaft 303. The bottom end of the steel wire rope 304 extends below the storage box 301 and is fixedly connected to the limiting beam 305. The limiting beam 305 is distributed between the two sets of column assemblies 1. By driving the winding shaft 303 to operate by the driving motor 302, the winding or unwinding of the steel wire rope 304 is realized, so as to realize the lifting operation of the limiting beam 305;

[0035] Reinforcing ribs 104 are welded and fixed between every two of the four columns 101, and there are no reinforcing ribs 104 between the two columns 101 that are close to each other in the two sets of column assemblies 1, which is used to provide space for the up and down movement of the limiting beam 305;

[0036] Limit guide wheels 307 are symmetrically installed on the side faces at both ends of the limiting beam 305. An annular groove is formed on the roller surface of the limit guide wheel 307, and the roller of the limit guide wheel 307 is attached to the outer wall of the column 101 through the annular groove.

[0037] In this embodiment: When assembling this gantry, its operation steps are as follows:

[0038] First, install the column assembly 1 at the preset position through the mounting base 102, then place the height-limiting beam 305 between the two groups of column assemblies 1 through a hoisting device (it should be noted that at this time, the height-limiting beam 305 is in a separated state from the steel wire rope 304). After that, lift the crossbeam assembly 2 and place it on the first connecting seat 103 on the two groups of column assemblies 1, and then fix the first connecting seat 103 and the second connecting seat 201 with bolts (it should be noted that embedded bolts are pre-buried at the preset position, mounting holes matching the embedded bolts are provided on the mounting base 102, and corresponding reinforcement holes are provided on the first connecting seat 103 and the second connecting seat 201. Additionally, it should be noted that the drive motor 302 and the winding shaft 303 are pre-installed on the storage box 301);

[0039] After completing the assembly of the crossbeam assembly 2 and the column assembly 1, the power supply of the drive motor 302 can be connected and the drive motor 302 can be started. The drive motor 302 drives the winding shaft 303 to rotate to unwind the steel wire rope 304, so that the bottom end of the steel wire rope 304 contacts the height-limiting beam 305. After that, connect the steel wire rope 304 and the height-limiting beam 305 (it should be noted that the steel wire rope 304 and the height-limiting beam 305 can adopt the existing technical structure, for example: connected by steel wire rope clamps). Then, run the drive motor 302 in the reverse direction to make the winding shaft 303 wind up the steel wire rope 304, so that the height-limiting beam 305 can be lifted to the required height;

[0040] Through the cooperation of the above-mentioned multiple parts, the height-limiting beam 305 can adapt to different height-limiting requirements, and the universality of the gantry is stronger. At the same time, the height-limiting beam 305 can be lifted and stored in the storage box 301 to facilitate the passage of ultra-high objects. In addition, the height-limiting beam 305 can be lowered to a position close to the road to facilitate the installation and replacement of limit signs and traffic signs.

[0041] Please refer specifically to Figures 1 to 4 , reinforcing plates 306 are symmetrically and fixedly connected to both ends of the limit beam 305. Fixed vertical plates 308 are arranged on the inner sides of the four columns 101. The fixed vertical plates 308 are welded and fixed with the reinforcing ribs 104. Bolts are sequentially passed through the mounting holes on the fixed vertical plates 308 and the reinforcing plates 306 to realize the height reinforcement of the limit beam 305;

[0042] The height of the fixed vertical plate 308 is greater than the height of the reinforcing plate 306, and the horizontal height of the bottom end of the fixed vertical plate 308 is the lowest use height of the limit beam 305.

[0043] In this embodiment: After the limiting beam 305 is hoisted to the required height, bolts can be passed through the mounting holes on the fixed vertical plate 308 and the reinforcement plate 306 to fix the height of the limiting beam 305, thereby ensuring the use safety. When the limiting beam 305 needs to be raised and lowered, the bolts can be removed and the driving motor 302 can be started. Compared with the traditional operation method of removing the entire gantry, it can effectively reduce the consumption of manpower and material resources, and the operation efficiency is faster.

[0044] Please refer particularly to Figures 1 to 4 , rectangular notches 4 are provided at one ends of the two first connection seats 103 and the two second connection seats 201 that are close to each other. The inner wall width of the rectangular notch 4 is greater than the distribution width of the limiting guide wheels 307 on both sides of the limiting beam 305;

[0045] The inner wall width and length of the storage box 301 are respectively greater than the distribution width of the limiting guide wheels 307 on both sides of the limiting beam 305 and the length of the limiting beam 305;

[0046] The height from the bottom end of the winding shaft 303 to the bottom end of the storage box 301 is greater than the height of the limiting beam 305.

[0047] In this embodiment: With this structure, the limiting beam 305 can be raised and stored in the storage box 301, which is convenient for transporting some ultra-high objects.

[0048] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
