Abstract

The utility model relates to a road width-limiting facility, in particular to a width limiting road block. The width limiting road block comprises a base and a long-board-shaped block body, wherein the block body is arranged above the base, and the middle of the bottom of the block body is movably connected with the base through a rotary shaft fixedly arranged at the center of the base; a horizontal first lock nose is arranged at the upper part on one side of the base; a horizontal second lock nose is arranged at the position, corresponding to the first lock nose, at one side end of the block body. Under normal circumstances, the base and the block body are locked through a lock, and thus the traffic of overweight and overrun vehicles can be effectively prevented through the block body. When oversize vehicles such as ambulances, fire fighting trucks, police cars and the like need to pass, the lock can be quickly opened in time, and the block body is rotated to increase the road width to allow the ambulances and relief vehicles to pass. In addition, the outer surface of the block body is coated with a reflective paint layer, thus drivers can see the width limiting road block even at night, and traffic accidents are avoided.

Description

A kind of limit for width road pier

(1) technical field

The utility model relates to a kind of highway limit for width facility, particularly a kind of limit for width road pier.

(2) background technology

At present, along with progressively completing of village of village engineering accessible by road, rural road pavement is progressively hardened, but due to passing through of some overweight overrun vehicles, highway pavement is caused greatly and threatened, tend to occur that rural road pavement damages serious phenomenon, brought certain difficulty and white elephant to rural highway engineering management simultaneously.The severe situation facing according to current rural road pavement, must take some necessary measures to limit the current of overweight overrun vehicle, existing technological means is that limit for width road pier is installed in highway pavement both sides, but existing limit for width road pier is common steel concrete block of wood, it not only limits overweight overrun vehicle traffic, also limited rescue simultaneously, fire-fighting, police the current of oversize vehicle that wait, although in the safety of having protected in varying degrees highway engineering, but also leave great potential safety hazard, affect the current of rescue and breakdown lorry, bring about great losses sometimes even can to national people's lives and properties.

(3) summary of the invention

The utility model is in order to make up the deficiencies in the prior art, a kind of limit for width road pier is provided, this limit for width road pier can limit overweight overrun vehicle traffic under normal circumstances, and in the time that rescue, fire-fighting, the oversize vehicle such as police need to pass through, can open rapidly in time again, allow to pass through, solved problems of the prior art.

The utility model is achieved by the following technical solution:

A kind of limit for width road pier, comprise that a base and is located at the pier body of the long slab shape of base top, pier body is flexibly connected with base by the rotating shaft that is fixedly arranged on base center in the middle of bottom, be provided with a horizontally disposed first lock nose at a upper lateral part of base, be provided with a horizontally disposed second lock nose in a side of the pier body position corresponding with the first lock nose.

Described base is cylindrical.

Described base and pier body are built and are formed by steel concrete.

Described the first lock nose and the second lock nose are embedded in respectively in base and pier body in advance.

Be coated with reflective enamelled coating at the external surface of pier body.

The beneficial effects of the utility model are: this limit for width road pier, under normal circumstances, base and pier body pin with lockset, so just can be by effectively passing through of the overweight overrun vehicle of containment of pier body, and in the time that rescue, fire-fighting, the oversize vehicle such as police need to pass through, can open rapidly in time again lockset, rotate pier body increase width of roadway and allow rescue, breakdown lorry to pass through; Human pilot in addition, applies reflective enamelled coating at the external surface of pier body, even if also can be seen this limit for width road pier, the generation avoiding traffic accident clearly so at night.

(4) brief description of the drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is front view of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the top view of Fig. 1;

Fig. 4 is use state diagram of the present utility model.

In figure, 1 base, 2 rotating shafts, 3 pier bodies, 4 first lock noses, 5 second lock noses, 6 reflective enamelled coatings, 7 locksets, 8 highway pavements.

(5) detailed description of the invention

For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in Fig. 1-Fig. 4, this embodiment comprises that a base 1 and is located at the pier body 3 of the long slab shape of base 1 top, pier body is flexibly connected with base 1 by the rotating shaft 2 that is fixedly arranged on base 1 center in the middle of 3 bottoms, be provided with a horizontally disposed first lock nose 4 at a upper lateral part of base 1, be provided with a horizontally disposed second lock nose 5 in a side of pier body 3 position corresponding with the first lock nose 4; Described base 1 is cylindrical, and described base 1 and pier body 3 are built and formed by steel concrete, and described the first lock nose 4 and the second lock nose 5 are embedded in respectively in base 1 and pier body 3 in advance, are coated with reflective enamelled coating 6 at the external surface of pier body 3.

This limit for width road pier symmetry is installed on the both sides of highway pavement 8, be used for limiting the highway width that is open to traffic, base 1 is embedded in highway pavement below 8 and the upper surface of base 1 flushes with highway pavement 8, pier body 3 is installed on base 1, pin pier body 3 and base 1 with lockset 7, so just can contain the current of overweight overrun vehicle; And in the time that rescue, fire-fighting, the oversize vehicle such as police need to pass through, open after the lockset 7 that pins pier body 3 and base 1, by pier body 3 clockwise or be rotated counterclockwise after 90 °, increasing width of roadway allows rescue, breakdown lorry to pass through, after rescue, fire-fighting, the oversize vehicle such as police pass through, again pier body 3 is resetted, with lockset 7 pinnings; The external surface of pier body 3 applies reflective enamelled coating 6, and driver can see this limit for width road pier, the generation avoiding traffic accident at night clearly.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
