Abstract
Description
Technical Field
[0001] The utility model relates to the field of height limit poles, in particular to a temporary road height limit pole. Background Art
[0002] The main function of a temporary height limit pole is to restrict vehicles from entering a specific area, ensure that vehicles can pass through the entrance smoothly, and avoid being unable to enter or causing congestion due to the excessive height of the vehicle.
[0003] For the existing temporary height limit poles, multiple height limit poles are mainly fixed by chains at the lower part of the frame-shaped support rods. When adjusting the height of the height limit poles, personnel need to climb to a height to manually adjust the height of the chains. Such adjustment not only wastes time, but also when personnel operate at the lower part of the height limit poles, it not only blocks traffic, but also is extremely prone to safety accidents; at the same time, when a relatively high vehicle collides with the height limit pole at a high speed, the height limit pole has no buffering effect, which affects the safety of the vehicle. Summary of the Utility Model
[0004] In order to solve the above existing problems, the utility model provides a temporary road height limit pole.
[0005] The utility model is realized through the following technical solutions:
[0006] A temporary road height limit pole includes a frame-shaped support rod, and height limit poles are arranged at the lower part of the frame-shaped support rod. The height of the height limit poles is adjusted through a wire rope pulley assembly.
[0007] Further optionally, two height limit poles are provided, and the height of each height limit pole is adjusted through a wire rope pulley assembly on one side.
[0008] Further optionally, the wire rope pulley assembly includes wire ropes fixed to the upper parts on both sides of the height limit pole. The two wire ropes pass through the pulleys supported correspondingly inside the frame-shaped support rod and are fixedly connected to a wire reel along a guide wheel.
[0009] Further optionally, the wire reel is installed inside a support base at the bottom of the frame-shaped support rod. The support base is inserted with a positioning insertion rod passing through the rotating shaft of the wire reel, and the end of the positioning insertion rod is fixed through a padlock.
[0010] Further optionally, the guide wheel is installed inside the turning node of the frame-shaped support rod.
[0011] Further optionally, the height limit pole includes two height limit short rods, and the two height limit short rods are connected through magnetic attraction blocks.
[0012] Further optionally, reflective strips are pasted on the height limit pole and the frame-shaped support rod.
[0013] Compared with the existing technology, the beneficial effects of the present utility model are as follows: The structure of the present utility model is simple and the operation is convenient. By adjusting the wire rope pulley assembly on the side of the frame-shaped support rod, the height adjustment of the height limit rod is realized, which is not only convenient and efficient in adjustment, but also has higher safety.

[0019] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:
[0020] As Figure 1 shown, a temporary road height limit rod includes a frame-shaped support rod 2, and a height limit rod 3 is arranged at the lower part of the frame-shaped support rod 2. The height of the height limit rod 3 is adjusted through a wire rope pulley assembly.
[0021] The height limit rods 3 are arranged in two, corresponding to the widths of the upper and lower passing roads on both sides. The height of each height limit rod 3 is adjusted through a wire rope pulley assembly on one side.
[0022] As Figure 2 , 3 shown, the wire rope pulley assembly includes wire ropes 4 fixed to the upper parts on both sides of the height limit rod 3. The two wire ropes 4 pass through the pulleys 5 supported correspondingly inside the frame-shaped support rod 2 and are fixedly connected to the wire reel 7 along the guide wheels 6.
[0023] As Figure 3 shown, the wire reel 7 is installed inside the support base 1 at the bottom of the frame-shaped support rod 2. A positioning insertion rod 9 passing through the rotating shaft of the wire reel 7 is inserted into the support base 1, and the end of the positioning insertion rod 9 is fixed through a padlock 10.
[0024] As Figure 2 shown, the guide wheel 6 is installed inside the turning node of the frame-shaped support rod 2, which plays a guiding role.
[0025] As shown Figure 4 in the figure, the height-limiting rod 3 includes two height-limiting short rods 31, and the two height-limiting short rods 31 are connected by magnetic attraction blocks 32.
[0026] Reflective strips are pasted on the height-limiting rod 3 and the frame-shaped support rod 2, and the reflective strips play a warning role at night.
[0027] The implementation principle of a temporary road height-limiting rod in an embodiment of the present application is as follows:
[0028] When adjusting the two height-limiting rods 3 at the lower part of the frame-shaped support rod 2, open the corresponding padlock 10, pull out the positioning plug rod 9 from the support base 1 to loosen the wire reel 7, rotate the rocker arm 8 clockwise, the rocker arm 8 drives the wire reel 7 to rotate to roll up and store the steel wire rope 4, and the two steel wire ropes 4 synchronously contract and move along the guide pulley 6 and the pulley 5 to lift the height-limiting rod 3 fixed at the lower part to achieve height adjustment. To lower the position of the height-limiting rod 3, rotate the rocker arm 8 in the reverse direction. After the adjustment is completed, insert the positioning plug rod 9 to limit the rotation of the wire reel 7 and use the padlock 10 to lock it to prevent loosening. In this way, by adjusting the wire rope pulley assembly on the side of the frame-shaped support rod 2, the height adjustment of the height-limiting rod 3 is realized, which is not only convenient and efficient in adjustment, but also has higher safety;
[0029] When a higher vehicle passes through the height-limiting rod 3 at the lower part of the frame-shaped support rod 2 and collides with it, due to the high impact of the vehicle, the two height-limiting short rods 31 magnetically attracted by the magnetic attraction block 32 will be disconnected to achieve the collision buffer of the height-limiting rod 3, ensuring the safety of the passing and colliding vehicles.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
