Description

A kind of roadblock

Technical field

The utility model relates to a kind of road roadblock, particularly the roadblock that uses at freeway toll station.

Technical background

Roadblock is widely used in places such as freeway toll station, police affairs inspection post, critical facility import and export inspection posts, is used for preventing that the suspect from driving illegally to make a breakthrough.But a large amount of at present roadblock structures of using are too complicated, and installation, maintenance inconvenience damages easily, and interception efficient is low, and can not be used with existing route denial cross bar.

The patent No. is that the utility model of ZL03251736.X discloses a kind of nail-plate roadblock, when its when road is normally current, need manually with the cross bar turn-off; When the suspect illegally makes a breakthrough, need manually to forward cross bar to intercepting position in advance, this needs certain reaction time and action time, so interception efficient is not high, and removes rotating horizontal pole before artificial, has increased operating personnel's personal dangerousness.Rotating horizontal pole is manually finished with the whole dependence of operation of removing cross bar each time, wastes time and energy, and can not realize automation.In addition, its cross bar rotates on horizontal plane, and the cross bar of freeway toll station rotation at present is all on vertical plane, so it can not link with existing freeway toll station cross bar equipment.

The utility model content

At the prior art above shortcomings, the purpose of this utility model be to provide a kind of simple in structure, maintenance is easy, simple to operate, safety is good, interception efficient height, and can unite the roadblock of use with the electronic cross bar in existing crossing.

The utility model is to realize above purpose by following technical scheme: a kind of roadblock, form by route denial device and tumbler, it is characterized in that, described route denial device is made up of the bore spine body, rotating shaft, bearing and the corresponding with it bearing support that are installed in the box body, the bore spine body is fixed in the rotating shaft, bearing is positioned at the rotating shaft two ends and is installed on the bearing support, and bearing support is fixed on the box body, covers on the box body to have to be used for the elongated slot that bore spine body thorn point exposes; Described tumbler comprises the conical gear one that is installed on rotating shaft one end, conical gear one and conical gear two engagements, on the axle of conical gear two the spring arm-tie is housed, counterbalance spring is equipped with in spring arm-tie top, back-moving spring is equipped with in spring arm-tie below, counterbalance spring is connected with wire rope, and the described wire rope other end links to each other with the rotating shaft of road interception cross bar.

Described loam cake is a circular arc, also can make the plane; Be distributed with bearing block in the described box body.

Compared to existing technology, this device has the following advantages:

1, route denial device of the present utility model is full mechanical device, need not any electric fixtures, when settling on the ground, is not afraid of the erosion of rainwater and dust, and safe and reliable, the life-span is long.

When 2, the utility model needed repairing, all parts can make progress from the inside after opening loam cake and directly take out convenient for maintaining or replacing.

3, the utility model can be that the rotating shaft of cross bar is flexible coupling by wire rope with the existing road occluding device, and is easy for installation.And do not change original electrical control system.

4, the utility model and existing road occluding device are after the rotating shaft of cross bar is connected, and can realize the complete electric automatic control of route denial, easier operation.

Description of drawings

Fig. 1 is the structural representation of the utility model roadblock.

Fig. 2 is Fig. 1 vertical view.

Fig. 3 is Fig. 1 lateral view.

Wherein, when the arrow above Fig. 1 left end represents that cross bar lifts wire rope be subjected to force direction, wire rope was subjected to force direction when following arrow represented that cross bar puts down.

The specific embodiment

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

Referring to Fig. 1, Fig. 2, from the figure as can be seen, this roadblock, be made up of route denial device and tumbler, the route denial device is made up of the bore spine body 2, rotating shaft 1, pair of bearings, the pair of bearing that are installed in the box body 13, wherein, bore spine body 2 is fixed in the rotating shaft 1, bearing 3 is positioned at the two ends of rotating shaft 1, and bearing 3 is installed on the bearing support 4, and bearing support 4 is fixed on the box body 13.Box body 13 is connected with loam cake 12 by screw, has elongated slot on the loam cake 12, so that expose bore spine body 2 thorn points.Described loam cake 12 can be made the circular arc of highway deceleration strip, also can make the plane.Be distributed with bearing block 5 in the box body 13, prevent that automobile is with loam cake 12 crimps.

Described tumbler comprises the conical gear 1 that is installed on rotating shaft 1 one ends, conical gear 1 and conical gear 27 engagements, on the axle of conical gear 27 spring arm-tie 8 is housed, counterbalance spring 10 is equipped with in the top of spring arm-tie 8, back-moving spring 9 is equipped with in the below of spring arm-tie 8, and counterbalance spring 10 is connected with wire rope 11.The other end of described wire rope 11 and existing road occluding device are that the rotating shaft of cross bar links to each other, and can realize complete electrical control.

This device is embedded in the ground of freeway toll station, and the wire rope of this device is linked to each other with the rotating shaft of existing freeway toll station cross bar.The utility model course of work is:

When 1, normally current, cross bar lifts, and wire rope 11 pulling spring arm-ties 8 upper ends by one group of conical gear 1 and conical gear 27, make rotating shaft 1 rotation, bore spine body 2 falls down and be hidden in the loam cake 12.When wire rope 11 continued pulling, during moment of torsion that the moment of torsion that back-moving spring power produces produces greater than counterbalance spring power, rotating shaft 1 stopped operating, and counterbalance spring 9 stretches elongated, thus compensation cross bar rotating shaft and this device rotating shaft 1 inconsistent amount of spin.

2, when needs stop automobile, charge station's cross bar is put down, this device rotating shaft 1 is under the effect of back-moving spring 9, bore spine body 2 thorn points are exposed to loam cake up, bore spine body 2 lower ends contact with box body 13, see Fig. 1 and Fig. 3, realize the spacing of rotating shaft 1, bear the pressure when piercing through tire simultaneously, reduce the rotating shaft distortion.When vehicle was made a breakthrough by force, bore spine body 2 stung the point meeting with the wheel puncture, thereby forces vehicle to stop.
