Technical Field
[0001] The utility model relates to the technical field of engineering construction, in particular to a height limiting pole. Background Art
[0002] During engineering construction and daily traffic, height limit poles are widely used under bridges with limited clear height, under buildings, and under pipelines, signal lines, and structures in construction sites.
[0003] Conventional height limit poles are characterized by high strength and strong impact resistance. They have a certain degree of safety for the protection structure. However, due to the excessive protection strength, vehicles that accidentally hit the poles are often severely damaged, and such height limit poles are usually accompanied by a large number of accidents.
[0004] In addition, conventional height limit poles are also easily damaged during use, and often need to be repaired before they can be reused in subsequent uses. Utility Model Content
[0005] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a height limiting pole which can play a height limiting role and reduce damage to the vehicle and the vehicle itself.
[0006] In order to achieve the above object, the utility model is implemented through the following technical solutions: a height limiting pole, comprising:
[0007] Support rods, wherein there are two support rods, and the two support rods are arranged opposite to each other along the transverse direction of the road;
[0008] A U-shaped support card, wherein a U-shaped support card is disposed at the top of each support rod, and the opening direction of the U-shaped support card is obliquely in the opposite direction of the impact;
[0009] A cross bar, both ends of which are inserted into the U-shaped support card, and when the cross bar is retracted and impacted, the end of the cross bar can slide out from the opening of the U-shaped support card;
[0010] A connecting chain, each end of the crossbar is connected to a connecting chain, and the other ends of the two connecting chains are connected to the support rod on the same side; and
[0011] A power-off sound and light alarm device, wherein the power-off sound and light alarm device is arranged on the support rod, and when the end of the cross rod is inserted into the U-shaped support card, the end of the cross rod can be pressed against the switch of the power-off sound and light alarm device to put the switch in a power-off state, and when the pressure on the switch of the power-off sound and light alarm device is released, the switch of the power-off sound and light alarm device is in a power-on state.
[0012] Furthermore, the support rod is a hollow rod, and the connecting chain is freely movably arranged in the support rod.
[0013] Furthermore, it also includes a counterweight, which is arranged in the hollow rod and can be slidably mounted on the connecting chain, and the weight of the counterweight is greater than the weight of the connecting chain.
[0014] Furthermore, the counterweight comprises a collar and a counterweight block, the collar is slidably mounted on the connecting chain, and the counterweight block is suspended on the collar.
[0015] Furthermore, an arc transition section is provided between the lower end of the U-shaped support card and the support rod, and the cross bar can slide into or out of the U-shaped support card along the arc transition section.
[0016] Beneficial effects of the utility model:
[0017] In the normal state, the two ends of the cross bar of the height limit pole are inserted into the two U-shaped support cards, and the end of the cross bar is pressed against the switch of the power-off sound and light alarm device, so that the switch is in the power-off state and the power-off sound and light alarm device does not sound an alarm.
[0018] When the vehicle is overheight, the moving vehicle hits the crossbar and knocks it off the U-shaped support card. When the crossbar falls, the pressure on the switch of the power-off sound and light alarm device is released, and the switch of the power-off sound and light alarm device is in the power-on state. The power-off sound and light alarm device sounds an alarm, so that the site management personnel and drivers will immediately find that the height limit device is activated and the vehicle is overheight and cannot pass. The vehicle will quickly slow down and stop, which greatly improves safety. When the vehicle leaves, just put the crossbar back to its original position.
[0019] By adopting the above-mentioned height limit pole, since the cross bar will leave the U-shaped support card during the collision, the damage to the vehicle and the damage to the height limit pole itself can be reduced. In addition, since the connecting chain has a certain length, the driver can be given a certain reaction time, thus changing the original hard collision mode to a contact and rebound mode after the collision, which greatly reduces the impact damage.

[0026] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0027] See also Figures 1 to 3 The utility model provides a height-limiting pole, including a support pole 100 , a U-shaped support card 200 , a cross bar 300 , a connecting chain 400 and a power-off sound and light alarm device 500 .
[0028] Specifically, there are two support rods 100, and the two support rods 100 are arranged opposite to each other along the horizontal direction of the road. A U-shaped support card 200 is arranged at the top of each support rod 100, and the opening direction of the U-shaped support card 200 is oblique to the opposite direction of the impact. The two ends of the cross bar 300 are inserted into the U-shaped support card 200, and when the cross bar 300 is impacted, the end of the cross bar 300 can slide out from the opening of the U-shaped support card 200.
[0029] Both ends of the crossbar 300 are connected to a connecting chain 400, and the other ends of the two connecting chains 400 are connected to the support rod 100 on the same side. When the power-off sound and light alarm device 500 is arranged on the support rod 100, and the end of the crossbar 300 is inserted into the U-shaped support card 200, the end of the crossbar 300 can be pressed against the switch of the power-off sound and light alarm device 500 to put the switch in a power-off state. When the pressure on the switch of the power-off sound and light alarm device 500 is released, the switch of the power-off sound and light alarm device 500 is in a power-on state.
[0030] Under normal conditions, both ends of the cross bar 300 are inserted into the two U-shaped support cards 200, and the ends of the cross bar 300 are pressed against the switch of the power-off sound and light alarm device 500, so that the switch is in the power-off state, and the power-off sound and light alarm device 500 does not sound an alarm.
[0031] When the vehicle is overheight, the moving vehicle hits the crossbar 300, knocking the crossbar 300 off the U-shaped support card 200. When the crossbar 300 falls, the pressure on the switch of the power-off sound and light alarm device 500 is released, and the switch of the power-off sound and light alarm device 500 is in the power-on state. The power-off sound and light alarm device 500 sends an alarm, so that the site manager and the driver will immediately find that the height limit device is activated and the vehicle cannot pass because of the overheight. The vehicle will quickly slow down and stop, which greatly improves safety. When the vehicle leaves, the crossbar 300 can be placed back to its original position.
[0032] By adopting the above-mentioned height limit pole, since the cross bar 300 will leave the U-shaped support card 200 during the collision, the damage to the vehicle and the damage to the height limit pole itself can be reduced. In addition, since the connecting chain 400 has a certain length, the driver can be given a certain reaction time, thus changing the original hard collision mode to a contact and bounce mode after the collision, which greatly reduces the collision damage.
[0033] It should be noted that the power-off sound and light alarm device 500 can be selected from the power-off sound and light alarm device 500 commonly used in the prior art. Generally, a power-off sound and light alarm device 500 with a power of 0.5W, a rated current of 300MA, a sound size of 50-110DB, a voltage of DC-12V, and a specification of 122*73*400MM can be used. The external power cord of the power-off sound and light alarm device 500 is a USB interface cable, and the length of the cable can be 1m.
[0034] In a preferred embodiment, in order to standardize the design, the support rod 100 can be set as a hollow rod, and the connecting chain 400 can be freely movably set inside the support rod 100.
[0035] As another preferred embodiment, the height limiting pole further includes a counterweight 600 , which is disposed in the hollow pole and can be slidably mounted on the connecting chain 400 , and the weight of the counterweight 600 is greater than the weight of the connecting chain 400 .
[0036] Through the counterweight 600, the cross bar 300 can be pulled back to the top of the support bar 100 after the vehicle is evacuated, thereby improving the convenience of use.
[0037] Specifically, the counterweight 600 includes a collar 610 and a counterweight 620. The collar 610 is slidably mounted on the connecting chain 400, and the counterweight 620 is suspended on the collar 610. When the connecting chain 400 moves, the collar 610 slides along the connecting chain 400, and the counterweight 620 is always located in the supporting rod 100.
[0038] As a more preferred embodiment, an arc transition section 700 is provided between the lower end of the U-shaped support card 200 and the support rod 100 , and the cross bar 300 can slide into or out of the U-shaped support card 200 along the arc transition section 700 .
[0039] When in use, under the guidance of the arc transition section 700, the cross bar 300 can slide into or out of the U-shaped support card 200 along the arc transition section 700. When the counterweight 600 is pulled, the cross bar 300 can be smoothly pulled back into the U-shaped support card 200, thereby reducing the manual installation method.
[0040] By adopting the above-mentioned height limit pole, since the cross bar 300 will leave the U-shaped support card 200 during the collision, the damage to the vehicle and the damage to the height limit pole itself can be reduced. In addition, since the connecting chain 400 has a certain length, the driver can be given a certain reaction time, thus changing the original hard collision mode to a contact and bounce mode after the collision, which greatly reduces the collision damage.
[0041] In addition, under the joint action of the counterweight 600 and the connecting chain 400, when the vehicle that hits the crossbar 300 is removed, the crossbar 300 can automatically return to the U-shaped support card 200, thereby reducing manual installation methods and improving the convenience of use and installation.
[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
