Abstract
The utility model discloses a road bridge overload limiting device which comprises a bearing platform and a roadblock rod, and is characterized in that a compression bearing cylinder is arranged below the bearing platform, the roadblock rod is arranged in a roadblock cylinder, a transportation oil pipe communicates the compression bearing cylinder with an electromagnetic valve and also communicates the electromagnetic valve with the roadblock cylinder, a backflow oil pipe communicates the roadblock cylinder with a check valve and also communicates the check valve with the compression bearing cylinder, and a circuit communicates the electromagnetic valve with an electro connecting pressure gauge an a power source. The road bridge overload limiting device can control the overload of vehicles automatically, has a low running cost, and can protect a road bridge well.
Description
Affiliated technical field
The utility model relates to a kind of highway bridge overload restricted driving device.
Background technology
Also do not have highway bridge overload restricted driving device in the market, road administration personnel use the mode limiting overload of vehicle of fine, and cost of labor is big, is difficult to control overload of vehicle, damages highway.
Summary of the invention
This reality has novelly provides a kind of highway bridge overload restricted driving device in order to address the above problem proposition, to its objective is, this highway bridge overload restricted driving device can be controlled overload of vehicle automatically, and running cost is low, and the highway bridge protection is good.
The technical scheme that adopts is: comprise bearing platform 1, Cleaning device fo street cleaning vehicle 10, it is characterized in that: compression load-bearing oil cylinder 3 is installed in the below of bearing platform 1, Cleaning device fo street cleaning vehicle 10 is installed in the roadblock oil cylinder 9, carry oil pipe 2 to be communicated with compression load-bearing oil cylinder 3 and electromagnetic valve 7, carry oil pipe 2 to be communicated with electromagnetic valve 7 and roadblock oil cylinder 9, backflow oil pipe 11 is communicated with roadblock oil cylinder 9 and one way valve 8, and backflow oil pipe 11 is communicated with one way valve 8 and compression load-bearing oil cylinder 3, and circuit 5 is communicated with electromagnetic valve 7 and electro connecting pressure gauge 4 and power supply 6.
Compared with prior art, this highway bridge overload restricted driving device can be controlled overload of vehicle automatically, and running cost is low, and the highway bridge protection is good.
Description of drawings
Fig. 1 is the utility model highway bridge overload restricted driving schematic representation of apparatus:
Among the figure: 1, bearing platform, 2, carry oil pipe, 3, compression load-bearing oil cylinder, 4, electro connecting pressure gauge, 5, circuit, 6, power supply, 7, electromagnetic valve, 8, one way valve, 9, the roadblock oil cylinder, 10, Cleaning device fo street cleaning vehicle, 11, the backflow oil pipe.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, compression load-bearing oil cylinder 3 is installed in 1 below of bearing platform, Cleaning device fo street cleaning vehicle 10 is installed in the roadblock oil cylinder 9, carry oil pipe 2 to be communicated with compression load-bearing oil cylinder 3 and electromagnetic valve 7, carry oil pipe 2 to be communicated with electromagnetic valve 7 and roadblock oil cylinder 9, backflow oil pipe 11 is communicated with roadblock oil cylinder 9 and one way valve 8, and backflow oil pipe 11 is communicated with one way valve 8 and compression load-bearing oil cylinder 3, and circuit 5 is communicated with electromagnetic valve 7 and electro connecting pressure gauge 4 and power supply 6.When overload automobile process bearing platform 1, surpass the setting value of electro connecting pressure gauge 4, circuit is connected, and electromagnetic valve 7 is opened valve, carries oil pipe 2 to send oil to roadblock oil cylinder 9, and Cleaning device fo street cleaning vehicle 10 protrudes upward, and the vehicle restriction is passed through.When the overload automobile withdrawed from bearing platform 1, one way valve 8 was opened valve, and backflow oil pipe 11 send oil to compression load-bearing oil cylinder 3, and Cleaning device fo street cleaning vehicle 10 is regained open to traffic.
