Description

Deceleration strip for municipal works

Technical Field

The utility model belongs to the technical field of the technique of municipal works and specifically relates to a deceleration strip for municipal works is related to.

Background

The speed reducing belt is one of vertical speed controlling measures, and can change the height or material of some road section to force the motor vehicle to decelerate based on the psychological and physiological principle so as to reach the aim of safety. The special traffic safety setting is generally arranged on road junctions, industrial and mining enterprises, schools, residential community population and other road sections requiring vehicle slow down and traffic accidents are easy to cause, and is a novel special traffic safety setting for reducing the running speed of motor vehicles and non-motor vehicles. The deceleration strip can cause the driver to generate violent vibration to generate uncomfortable feeling when passing at a high speed, deepens the unsafe doubt of the driver and prompts the driver to select a low speed to drive. However, the existence of the deceleration strips can also cause the automobile to be subjected to strong impact force in the driving process, so that the automobile body is damaged, and potential safety hazards exist, therefore, some deceleration strips can take striking colors or marks, and drivers can notice the existence of the deceleration strips in advance to actively reduce the speed of the automobile.

A vehicle speed bump with a light reflecting structure, which is disclosed in the prior publication No. CN2813699, comprises a monolithic speed bump body, a fixed part and a connecting part; the single deceleration strip bodies are fixedly connected into an integral structure through connecting parts and are connected with a road surface through the fixing parts. The vehicle speed bump further comprises a light reflecting structure, and the light reflecting structure is arranged inside and on the surface of the speed bump body; the reflecting structure enables the existence of the speed bump to be more obvious, and enables a driver to notice the speed bump to decelerate in advance.

The above prior art solutions have the following drawbacks: when an electric bicycle or a bicycle passes through a deceleration strip, even if the bicycle actively decelerates to run by noticing the existence of the deceleration strip, people still feel uncomfortable feeling caused by up-and-down bump by riding due to the limitation of a damping system of the bicycle and the limitation of the height of the deceleration strip when the bicycle passes through the deceleration strip. In some road sections, the deceleration strip is several, and the discomfort caused is stronger.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 5, the deceleration strip for municipal engineering disclosed by the invention comprises a deceleration strip body 1, a round head 4 and a reflector 5; 1 component part of deceleration strip body includes bellying 2, and the sunken gentle portion 3 that forms between bellying 2 and the bellying 2, bellying 2 and the gentle portion 3 of flat connection in turn, and the interval is even, and the bicycle can nimble select the route through the gentle portion 3 when passing through the deceleration strip, alleviates the uncomfortable sense that violent vibrations arouse when passing through the deceleration strip.

The bumps 2 and the flat parts 3 are in smooth transition, a connecting position 7 is arranged between every two bumps 2, the connecting position 7 is located in the center of the flat part 3 and is fixed through a tenon-and-mortise structure, one side of the flat part 3 is a tenon, and the other side of the flat part 3 is a mortise, so that the connecting strength of the deceleration strip can be reinforced, and the deceleration strip is not easy to fall off; the round head 4 and the speed bump body 1 are also provided with a connecting position 7, two sides of the connecting position 7 are respectively provided with 2 expansion screws 8 which are tightly fixed with the ground, the expansion screws 8 are metal expansion screws, and the cylinder 9 is a stainless steel cylinder; the arrangement direction of the 2 expansion screws 8 is consistent with the driving direction of the wheels; expansion screw hole 6 is in gentle portion 3 department, during fixed expansion screw 8, and there are 3 incisions in drum 9's lower half, and when expansion screw 8 upwards rotated, drum 9 was strutted, just can firmly be fixed subaerial, and reuse powerful glue seals expansion screw hole 6 solid, can prevent that the vibrations that the vehicle brought from causing the screw pine to take off. The connecting arrangement can effectively prevent the situation that the components are not firmly connected and fall off, damage or even influence the normal running of the vehicle when the vehicle passes through.

The deceleration strip is made of rubber, the upper surface of the deceleration strip is provided with oblique-strip anti-skid lines, the color of the deceleration strip is a color of warning stripes with alternate yellow and black, the convex part 2 is adhered with an upward triangular reflector 5, and the reflector 5 is a high-brightness reflective film; the yellow and black warning stripes can be effectively separated from the color of the road surface, and play a role in prompting mainly in an environment with sufficient brightness; the triangular high-brightness reflective film attached to the protruding portion 2 can play an obvious prompting role in gathering light rays, particularly in a dark environment, and the triangular shape can indicate the position of the protruding portion 2 of the deceleration strip of a driver, so that the driver can better realize that the deceleration stably passes through the gentle portion 3.

The height of the convex part 2 of the speed bump is less than that of the chassis of the automobile, so that the speed bump can be prevented from being scraped to the chassis; concrete is filled in the inner cavity 10 of the boss 2, so that the weight of the speed bump can be increased, and the effect of enhancing the stability of the speed bump is achieved; the width of the flat part 3 can allow a bicycle tire with a general specification to run through and feel slight vibration.

The implementation principle of the embodiment is as follows: when the vehicle passes through, the speed can be reduced, and the flat and slow part 3 with lower height is selected to pass through, so that the strong stimulation of the deceleration belt to the driver can be effectively reduced; when the vehicle still passes through at high speed, the driver cannot see the structures of the deceleration strip with different heights in time, and the deceleration strip brings uncomfortable feeling of severe vibration to the driver, so that the driver can decelerate.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
