Abstract
The utility model relates to a hydraulic lifting device for a roadway. The hydraulic lifting device comprises a hydraulic station, oil cylinders and a speed-down plate, wherein the hydraulic station is arranged beside the roadway or under the ground, an electric non-return valve is arranged inside the hydraulic station, the hydraulic station is connected with the oil cylinders above the hydraulic station, and the oil cylinders are connected with the speed-down plate above the oil cylinders. The hydraulic lifting device has the characteristics of convenience in use, flexible switching, simple structure and the like. The utility model has the benefits that when the hydraulic lifting device is in use or is idle, that is, the idle speed-down plate can be retracted through the oil cylinders and hidden in the roadway, so as to keep level with the roadway; and when speed-down warning is required, the speed-down plate can be lifted to a certain height through the hydraulic oil cylinders, so as to achieve the purpose that the passing vehicles bumps and meanwhile drivers are reminded of speed down.
Description
Technical field
The utility model relates to a kind of road surface Reduced Speed Now device, relates in particular to a kind of road surface hydraulic lift.
Background technology
On urban road, through regular meeting run into the situation that a certain highway section needs braking action of vehicle to travel in certain special time (as school's highway in front of the door, go to school, classes are over or in the period at noon), in addition, but other period cruising then.Be directed to this situation, at present the way that adopts is: adopt literal make the speed(-)limit sign board or on the road surface the fixing brake flap of dress, but these two all exists different shortcomings, the former is a text prompt, does not notice as the driver that prompt text still can not slow down and crosses; And the latter is a fastening devices, and in the period that does not need to slow down, it can influence cruising again.
Summary of the invention
At above defective, the utility model provides a kind of simple in structure, easy to use, the road surface hydraulic lift that can effectively remind the driver to slow down, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of road surface hydraulic lift comprises Hydraulic Station, oil cylinder, brake flap, and Hydraulic Station is arranged at roadside or underground, and Hydraulic Station inside is provided with electronic one way valve, and described Hydraulic Station is connected with the oil cylinder of its top, and this oil cylinder connects the brake flap of its top.
The beneficial effect of road surface described in the utility model hydraulic lift is: have easy to use, switch is flexible, characteristics such as simple in structure, be mainly reflected in and use when idle, brake flap when promptly idle can be hidden in the road surface by the oil cylinder withdrawal, thereby can keep concordant with the road surface; When needs slow down to be reminded, hydraulic jack made brake flap rise certain altitude, reached to make to cross vehicle and jolt the purpose of reminding the driver to slow down simultaneously.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described road surface of the utility model embodiment hydraulic lift.
Among the figure:
1, Hydraulic Station; 2, oil cylinder; 3, brake flap; 4, electronic one way valve; 5, motor main body; 6, the pump housing.
The specific embodiment
As shown in Figure 1, the described road surface of the utility model embodiment hydraulic lift, comprise Hydraulic Station 1, oil cylinder 2, brake flap 3, described Hydraulic Station 1 is arranged at roadside or underground so that at the automatic actuating motor of set period PLC, described Hydraulic Station 1 inside comprises the motor main body 5 and the pump housing 6, and Hydraulic Station 1 inside is provided with electronic one way valve 4, and described Hydraulic Station 1 is connected with the oil cylinder 2 of its top, this oil cylinder 2 connects brake flap 3, and this brake flap 3 keeps being horizontally disposed with the road surface; During work, pressure oil rises brake flap 3 to oil cylinder 2 by lift valve, and it is uneven that the road surface keeps, and motor is shut down; Period finishes by the time slow down, electronic one way valve 4 charged oil cylinder 2 pressure releases, and brake flap 3 is depressed by the vehicle of conducting oneself with dignity and cross, and keeps concordant with the road surface.
