CN101722854A - Automatic controller for overrun and overload of heavy vehicles - Google Patents

Abstract

The invention relates to the problems of overrun and overload of heavy vehicles, and as for roads, effectively controls the damage of overweight vehicles on road surfaces, better protects the service life of the roads, and simultaneously reduces many traffic accidents. The key points of the invention are as follows: (1) in the first method, the principle of an electronic weigh bridge is used and an electromagnetic tractor is installed for opening pins and controlling a vehicle to stop or drive; and (2) in the second method, electricity is not used and the principle of a spring scale is used (see figure 3-4).When a plane surface of a controller drum bears weight in a range exceeding, for example, 50 tons, the plane surface drops 5cm and then is separated from 6 pins above at each side, and the drum rotates along with wheels; and when the weight is reduced to 50 tons, 6 springs are in the original positions, when the wheels rotate, the 6 pins at each side penetrate through holes of the steel drum sequentially, and then the vehicle can drive. The automatic controller is mainly used at toll gates or main roads for controlling various large heavy vehicles and overweight vehicles and safeguarding lives and property of a country and people.

Description

Automatic controller for overrun and overload of heavy vehicles

Technical field: this controller is domestic and international initiative, and theory of machines is simple, alerting ability good, dismantle easy to maintenancely, controls various heavy motor vehicles specially to the travelling of the overweight overload of highway, and is the service life and the security of the lives and property of protecting highway pavement.Simultaneously, not to any transformation of heavy-duty vehicle (as engine power) with restrict his self-ability, benefit the nation and the people.

Background technology:

First method: see six sensors are installed on (elevation drawing 3, exploded drawings 4) controller, connect wiring and close, open whole pins on the electromagnetic traction device above switching at once to passing to as time more than 50 tons, the steel cylinder is separated with pin, and rotate, vehicle is just impassable.When weight reaches as 50 ton hours, sensor cuts off the power supply the electromagnetic traction device at once, and whole pins is all fallen on the steel cylinder and rotated, and passes pin-and-hole on the cylinder and resting barrel, and vehicle can travel.

Second method: not electricity consumption, see shown in (elevation drawing attached 3, exploded drawings attached 4) with spring, as the road predetermined weight is 50 ton hours, so to take advantage of weight be 1.3 tons to every spring, when overweight, the controller base 5cm that just sinks, steel just roll with top pin and separate, cylinder can not stop along with wheel revolutions, can't travel.When weight is got back to the weight of regulation, controller with regard on move, with dowelled joint, with wheel pin is all passed cylinder after, vehicle can travel.

Summary of the invention: first kind is by pedestal, is placed with six sensors of six roots of sensation steel cylinder connection bearing above, and 1 wiring is closed, 4 electromagnetic traction devices, and totally 12 pins are formed, with the electric control of going up a hill.

Second kind is by six roots of sensation spring, and six roots of sensation steel cylinder connection bearing is arranged above the pedestal, is made up of 12 pins, when steel rolling face is subjected to overweight pressure, separate the back with regard to sinking with whole pins and control, more than can be with first kind of electricity consumption, second kind of not electricity consumption, use also can unite two into one.

The specific embodiment: places, thoroughfare such as the highway outpost of the tax office of this equipment and toll station will be installed, dig out required length and width, the degree of depth under roadbed, six roots of sensation steel rolls face and the road surface secured in parallel gets final product.

Claims (1)

1. its principal character of this automatic controller for overrun and overload of heavy vehicles is:

1. first method: utilize electronic loadometer to claim principle, add that the electromagnetic traction device opens pin and controls stopping of overweight car, can travel when reaching the weight of defined.

2. second method: must be through strict pressure testing with every on spring, in the weight range of regulation (such as the total weight that must not surpass 50 tons of weights, so every spring is taken advantage of weight about 1.3 tons), when weight is just saturated, (see accompanying drawing 3), six roots of sensation pin has just passed the steel cylinder, and vehicle can travel.Otherwise the steel rolling drum surface just sank when weight surpassed, and had separated with top six roots of sensation pin, rotated with the road wheel, and at this moment vehicle just can't travel.This technology does not all have the difficult problem of fine solution at home and abroad, and manufacturing is simple, alerting ability is good, easy to maintenance, has protected the service life and the people's lives and property of highway effectively, and I require to obtain rights protection.
