Abstract

The invention relates to a roadblock used for stopping vehicles and controlling the road traffic direction. The roadblock is composed of a slope body and rolling elements, the slope body is transversely arranged on the road surface, the rolling elements such as idler wheels and roll balls are installed on one slope surface where the vehicles run in the converse direction, when the vehicles climb in the converse direction, wheels slip and lose adhesive force, and the vehicles cannot climb over the slope body. Rolling elements are not arranged on the other slope surface of the slope body, and when the vehicles run in the forward direction, the vehicles climb over the slope surface as smoothly as passing through a deceleration strip. The rolling elements can be used in cooperation with a one-way bearing to be installed on the top of the slope of the slope body. The roadblock used for stopping vehicles and controlling the road traffic direction is simple in structure, convenient to install and use and long in service life.

Description

Control the vehicle barrier of road direction

Technical field

The present invention relates to a kind of stopping or the device of restricting traffic, relate in particular to a kind of vehicle barrier of controlling road direction.

Background technology

Many roads have the restriction of one-way trip, but drivers are often because careless, reverse driving quite a way just discover one's mistakes.Should invent a kind of handy unidirectional roadblock and solve this problem, while allowing driver sail crossing into, just can initiatively point out him, or further can allow vehicle drive in the wrong direction to sail into.Here analyze two kinds of disclosed technology.

A kind of control one-way traffic of application number-CN201210357348 denomination of invention and damping slowed down road-block.

This scheme has following shortcoming: the car that chassis is short, while striding across, chassis is easily scratched.Its profile is totally different, before easily making driver feel uncertain not.Complex structure, the rear spring of exposing to the sun and rain gets rusty easily.Each car spring of crossing will compress once, shorten spring life.Device gets rusty or foreign material jam, may affect current.

A kind of road barricade of application number CN200420073214 denomination of invention.This scheme has following shortcoming: during installation, need on road, dig pit, device is imbedded to underground, sleet sky ponding will make device be immersed in water, get rusty and break down.Complex structure, has been used braking components besides, and this is consumable accessory, Maintenance Difficulty.

The present invention will overcome these shortcomings, creates a kind of simple in structure durablely, and vehicle compatibility is strong, install and use simple and safe, the acceptable device of driver.

Summary of the invention

Innovation scheme 1 of the present invention is:

One slope body is set, and to be horizontally placed on ，Gai slope, road surface body cross section up-narrow and down-wide, has slope, two sides.In the face of the rolling element of roller, ball, roller bearing, cylinder one class is installed on reverse driving vehicle domatic, when vehicle drives in the wrong direction climbing, wheel-slip loses adhesive power, cannot get over slope body.The domatic rolling element that do not arrange of opposite side, during vehicle forward travel, climbing gets over smoothly just like crossing deceleration strip, and can not allow driver feel uncertain.

Certainly, such scheme 1 also has his shortcoming: drive comfort level not so good.When wheel gets over top, slope descending, because rolling element causes wheel-slip, vehicle is than crossing slip under general deceleration strip fast.But problem is little, and one flaw cannot mar the jade, multiplexly will be accustomed to several times.

For the not good shortcoming of scheme 1 comfort level, I improve once again, form innovation scheme 2:

One slope body is set and is horizontally placed on road surface, two side slopes do not arrange rolling element.Introduce key element: cover has the roller of unilateral bearing.This roller is fixed on Po Ding, because this roller housing has unilateral bearing, and such as clockwise direction is rotatable, locking so counterclockwise.Wheel is climbed to behind top, slope, is pressed on roller, if reverse driving, the roller rotation on top, slope causes wheel-slip to lose adhesive power, and vehicle is top, slope more only.Vehicle can be hung reverse gear and return after driving in the wrong direction and being obstructed, during vehicle rollback, and due to wheel reverse rotation, unilateral bearing locking, wheel is obtained adhesive power, and this device can not bottled up car.The roller on top, forward travel Shi， slope is because of unilateral bearing locking, and vehicle normally gets over slope body.And during due to descending, domatic without rolling element, driving is experienced the same with excessively common deceleration strip, comfortable compared with scheme 1.But this scheme also has his shortcoming: just skid in retrograde top, wheel Dao Liao slope, and this may cause some retrograde car to accelerate to break through top, slope.I think that this scheme is more suitable for comfortableness to require the transport need in contour end consumption place, high high-grade hotel, because the vehicle chassis of this class occasion is short, the speed of a motor vehicle is low, and driver and crew are worthy of careful study to comfort level.

Below in conjunction with accompanying drawing, detailed technology of the present invention and cases of design are described.

Fig. 1 is the result of use diagram of innovation scheme 1.

Fig. 2 is the result of use diagram of innovation scheme 2.

Fig. 3 adopts spheroid steel ball to be nested in domatic design example, has dug a plurality of match plays on domatic, and steel ball is placed in one, and the steel plate of the circular hole that gathers is pressed in domatic fixing, prevents that steel ball from coming off.The design is simple in structure.

Fig. 4 is that cover has the roller of bearing and transverse axis to be installed on domatic design example, has dug a plurality of grooves on domatic, and cover has the roller of bearing and transverse axis, and its transverse axis is fixed on domatic.

Fig. 5 is that cover has the roller of unilateral bearing and transverse axis to be installed on the design example on top, slope, and a plurality of grooves have been dug on top in slope, and cover has the roller of unilateral bearing and transverse axis, and its transverse axis is fixed on Po Ding.

Feasibility analysis.

1. type of vehicle Adaptability Analysis.

The car of front-wheel drive, as most Audi, because driving wheel skids, front-wheel cannot get over slope body.The car of rear wheel drive is as BMW, and rear drive sprocket can promote front-wheel and get over slope body, but trailing wheel climbing still can be skidded and cannot get over slope body.4-wheel driven car, unless on the way according to the distance of about 2.3 meters ~ 3.3 meters of vehicle wheelbase, horizontal Liang Pai slope body, otherwise it is had no way out, because its front-wheel can lean on trailing wheel to promote to advance while skidding, can forwardly take turns to drag again during rear wheels slip and advance.

But the 4-wheel driven car on road surface is only a few after all, open the 4-wheel driven car only a few especially that malice is driven in the wrong direction again, most car two-wheel drive, wherein the people of front-wheel drive is again the overwhelming majority wherein, so one flaw cannot mar the jade.

Apparatus of the present invention are easy for installation, without digging pit at road.Device protrudes from ground, and the bearing that uses of rolling element can be sealing oiliness bearing, is not durablely afraid of sleet.Element is few, good maintenance simple in structure.
