Description

Technical Field

[0001] This utility model relates to the field of height restriction frame technology, and in particular to a height restriction frame for roads and bridges. Background Technology

[0002] Height restriction barriers are primarily used as portal frames at the entrances of bridges, culverts, tunnels, and roads. They are generally welded steel structures and serve to protect bridges, culverts, and tunnels. They have signs indicating the height restriction in meters to warn vehicles and protect the road. Height restriction barriers are broadly divided into two types: fixed height restriction barriers and adjustable height restriction barriers.

[0003] Some height-adjustable height restriction frames mount their bottom ends on two concrete piles. The two concrete piles and the height restriction frame work together to restrict the height and width of roads and bridges. However, the spacing between the two concrete piles is specific, which means that the height restriction frame can only perform limited width restriction operations during use, reducing its practicality. Therefore, a new type of height restriction frame is needed to solve the above problems. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] like Figures 1 to 5As shown, a road and bridge height restriction frame includes two base piles 1 made of concrete. Each base pile 1 has a column 2 fixedly installed on its top side. Each column 2 has a height adjustment structure 3, and a crossbeam 4 is connected to each height adjustment structure 3.

Two indicator sign structures 5 are provided on the crossbeam 4. Each of the two columns 2 has a storage groove 6 on one side. A rotating shaft 7 is rotatably connected to the inner wall of each storage groove 6. Hollow plates 8 are fixedly connected to the outer surface of each rotating shaft 7. Limit grooves 9 are provided on the two symmetrical sides of each hollow plate 8. Extension rods 10 are slidably connected inside each hollow plate 8. Under normal conditions, the hollow plates 8 and extension rods 10 are located inside the limit grooves 9. Locking threaded rods 11 are fixedly connected to the two symmetrical sides of each extension rod 10. Both sides of the hollow plate 8 are threaded with locking nuts 12. Both ends of the two rotating shafts 7 are fixedly connected with turntables 13. Several fixing holes 14 are opened on one side of each of the two turntables 13. Fixing bolts 15 are threadedly connected to one side of each of the two columns 2. When it is necessary to adjust the road width limit, the fixing bolts 15 are moved out of the inside of one fixing hole 14 from the column 2. Then the hollow plate 8 drives the extension rod 10 to rotate to a horizontal state. Then the fixing bolts 15 pass through the inside of the fixing hole 14 and connect with the column 2, thereby fixing the turntable 13. At this time, the rotating shafts 7 no longer rotate, thus fixing the hollow plate 8 in a horizontal state. Then the extension rod 10 is moved out of the inside of the hollow plate 8. The extension rod 10 is adjusted to a suitable position according to the width limit distance. Then the locking nuts 12 are tightly fitted to the hollow plate 8, thereby fixing the extension rod 10 in a suitable position. At this time, the width limit operation is performed by the hollow plate 8 and the extension rod 10 together.

[0025] As an optional technical solution of this utility model, the height adjustment structure 3 includes an adjustment groove 301, an adjustment bolt 302, a lifting rod 303, and adjustment holes 304.

Several adjustment holes 304 are provided on one side of the lifting rod 303. When adjusting the height of the road bridge height restriction frame, the lifting rod 303 is moved out from inside the adjustment groove 301. At this time, the crossbeam 4 moves accordingly. The crossbeam 4 is adjusted to a suitable height according to the actual height restriction situation. Then, the adjustment bolt 302 is connected to the adjustment hole 304 of the appropriate height to fix the lifting rod 303, thereby fixing the crossbeam 4 at a suitable height.

[0026] As an optional technical solution of this utility model, the indicator sign structure 5 includes indicator text 501, indicator blocks 502, indicator numbers 503, positioning holes 504, and positioning bolts 505.

The indicator 503 is 0-9. Multiple sides of the indicator block 502 are provided with positioning holes 504. The top side of the crossbeam 4 is threaded with four positioning bolts 505. After adjusting the crossbeam 4 and the extension rod 10 to a suitable position, the indicator block 502 drives the indicator number 503 to rotate, so that the height limit indicator number 503 rotates to the position facing the road entrance. At this time, the positioning bolts 505 correspond to the positions of the positioning holes 504 in the appropriate positions. Then, the positioning bolts 505 are connected to the positioning holes 504 to fix the indicator block 502 in the appropriate position.

[0027] As an optional technical solution of this utility model, the hollow plate 8 is located inside the storage groove 6. The hollow plate 8 is rotatably connected to the storage groove 6. The thickness of the hollow plate 8 is adapted to the width of the storage groove 6. The length of the hollow plate 8 is less than the length of the storage groove 6, so that the hollow plate 8 can rotate smoothly and be stored inside the storage groove 6.

[0028] As an optional technical solution of this utility model, the locking threaded rod 11 passes through the inside of the limiting groove 9, and the locking threaded rod 11 is slidably connected with the limiting groove 9, so that the locking threaded rod 11 can move smoothly along the direction of the limiting groove 9.

[0029] As an optional technical solution of this utility model, the fixing bolt 15 is positioned corresponding to the fixing hole 14, and the size of the fixing bolt 15 is adapted to the fixing hole 14, so that the fixing bolt 15 can be smoothly connected to the fixing hole 14.

[0033] 1) Secure the fixing bolt 15 to the column 2 and remove the fixing bolt 15 from inside a fixing hole 14;

[0034] 2) Rotate the hollow plate 8 to a horizontal position, and make the fixing bolt 15 pass through the inside of the fixing hole 14 and connect with the column 2, thereby fixing the turntable 13 and fixing the hollow plate 8 in a horizontal position.

[0035] 3) Move the extension rod 10 out of the hollow plate 8 and adjust the extension rod 10 to a suitable position according to the width restriction distance;

[0040] 8) Connect the positioning bolt 505 to the positioning socket 504 and fix the indicator block 502 in the appropriate position. At this time, the driver can be reminded by the indicator number 503 to perform height and width restriction operations through the road and bridge height restriction frame.
