(2) Through setting up infrared alarm for during the vehicle striking, the horizontal pole takes place to deflect, and infrared alarm can report to the police, sends alarm sound and sends alarm information to relevant unit, provides basis and facility to the pursuit of the person of being responsible for the later stage.

Drawings

FIG. 1 is a schematic view of a front sectional view of a municipal works height limiting device provided by the present invention;

FIG. 2 is an enlarged view of portion A of FIG. 1;

reference numbers in the figures: 1. the device comprises a stand column, 2, a mounting groove, 3, a mounting rod, 4, a cross rod, 5, a spiral groove, 6, a sliding rod, 7, a bearing, 8, a spring, 9, a buffer sleeve and 10 and an infrared alarm.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1-2, in an embodiment of the present invention, a municipal works height limiting apparatus includes: two stands 1, two stand 1 fixed mounting is in the both sides of highway respectively, two the top of stand 1 all seted up mounting groove 2, install installation pole 3 in the mounting groove 2, the top of installation pole 3 extends to outside mounting groove 2, the top fixed mounting of installation pole 3 has horizontal pole 4, the one end of horizontal pole 4 extends to in the middle of the road, be equipped with helicla flute 5 in the mounting groove 2, fixed mounting has four slide bars 6 on the installation pole 3, the one end of slide bar 6 extends to in the helicla flute 5.

Through setting up stand 1, installation pole 3, helicla flute 5 and slide bar 6 for horizontal pole 4 can produce the deflection and upwards rise certain height when receiving the striking because of the vehicle is super high, thereby has protected vehicle and limit for height device to a certain extent.

And bearings 7 are fixedly arranged at one ends of the sliding rods 6, and the bearings 7 are in rolling connection with the spiral grooves 5.

The bearing 7 is a sealed bearing.

By providing the seal bearing 7, the friction between the slide rod 6 and the spiral groove 5 is reduced, thereby enabling the rotation of the cross rod 4 to be more flexible and the deflection to be quicker.

Two the bottom of mounting groove 2 all is equipped with spring 8, spring 8's both ends with the bottom of mounting groove 2 and the bottom fixed connection of installation pole 3.

The cross bar 4 can return to the initial position after impact deflection by providing a spring 8.

And the two cross rods 4 are fixedly provided with buffer sleeves 9.

By providing the cushion collar 9, damage to the vehicle and the device from impact is reduced.

And one ends of the two cross rods 4 close to each other are fixedly provided with infrared alarms 10.

Through setting up infrared alarm 10 for when the vehicle striking, horizontal pole 4 takes place to deflect, and infrared alarm 10 can report to the police, sends alarm sound and sends alarm information to relevant unit, provides the foundation and facilitates to the pursuit of the person of being responsible for in the later stage.

The utility model provides a municipal works limit for height device's theory of operation as follows:

when the top of an ultrahigh vehicle collides with the buffer sleeve 9 of the device, the vehicle collides and compresses the buffer sleeve 9, the transverse rod 4 is pushed to rotate, when the offset of the infrared alarm 10 reaches the alarm design, the alarm gives out alarm sound and sends alarm information, meanwhile, the transverse rod 4 rotates to drive the installation rod 3 to rotate, the installation rod 3 rotates to drive the sliding rod 6 to rotate, the sliding rod 6 rotates to drive the bearing 7 to spirally move along the spiral groove 5, meanwhile, the installation rod 3 rotates to drive the spring 8 to twist and deflect until the vehicle stops colliding, the spring 8 gradually returns to the initial state and drives the transverse rod 4 to return to the initial state, and at the moment, the alarm 10 stops alarming.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
