Description

FIXING TYPE AXLE WEIGHTING APPARATUS FOR MEASURING WEIGHT ACCURATELY OF WRONG ENTRANCE OF OVERLOAD VEHICLE}

The present invention relates to a fixed scale lifter for detecting the weight of an overloaded cargo vehicle, and more particularly to accurately detect the weight of a vehicle even when the vehicle is biased to the left and right sides at a fixed scale lifter installed at an overload checkpoint or a highway toll gate. The present invention relates to a stationary crane that has improved the crane structure.

In general, a weight lifter is a device for detecting an overload vehicle to protect a road or a bridge. Device.

Such a scaler is a fixed scaler that is always buried on the road and a movable scaler that can be measured while moving from place to place by lightening the weight to move.

In this case, the fixed scale lifter is a device installed at an overload checkpoint or a highway toll gate, and is installed in a large amount of traffic and is capable of dynamic (dynamic) metering. Dynamic weighing is a method in which a vehicle passes through an axle plate at a low speed of 10 km or less.

These stationary scalers are largely divided into car and office equipment to detect the weight of the vehicle. The lane facility is installed on the roadway through which the vehicle passes at the overload checkpoint or highway toll gate, and the weight of the vehicle wheel is applied to the detection unit to output the internal signal by deformation of the strain gauge or load cell. The facility converts an electrical signal applied to a detection unit installed on a roadway into a weight, processes it, and provides a controller for notifying a driver or a worker through a peripheral input / output device after constructing a database (DB).

On the other hand, such a fixed axle structure is a situation that is continuously improving the structure to reduce the error rate, such as the error and the prevention of the shaft operation according to the speed of the running vehicle.

However, despite the improvement of the fixed crane structure, to date, the crane structure has been used by the vehicle driver to bias the vehicle to the left or right side of the crane structure when passing through the crane structure so that a part of the rear wheel of the vehicle may be removed from the detection rotor. Therefore, it is difficult to substantially prevent unauthorized entry so that the weight detection value is lower than the actual weight of the vehicle.

In more detail, as shown in FIG. 1, the conventional stationary condenser structure is installed on the underground frame 11, which is long embedded in the left and right sides on the roadway, and is installed on the left and right sides of the upper portion of the underground frame 11, respectively. Of the left and right wheels passing through the center of the middle of the underground frame 11 between the left and right measuring pads 12 and 13 and the left and right measuring pads 12 and 913 provided with a load cell therein to measure the weight of the wheel. It is configured to include a dummy (14).

Here, the center pile 14 is not a configuration for measuring the weight of the wheel, but an auxiliary configuration for filling the space between the pair of left and right measurement pads 12 and 13 in the underground frame. It is installed at the same height as the measurement pads 12 and 13.

However, the vehicle driver does not drive both the left and right rear wheels of the pair of vehicles passing through the measurement pads 12 and 13 when the vehicle enters the vehicle with a concentrator installed on the road, but the conventional fixed shaft described above. The weight applied to the rear wheel of the vehicle by intentionally entering the vehicle to the left or right side by exploiting the structure of the heavy machinery and entering the inner wheel A1 through the upper portion of the center pile 14 in the pair of rear wheels. Some of these are distributed undetected through the central pile 14 so that the vehicle can enter the vehicle so as to be detected to be lower than the actual weight of the vehicle.

This is the same as weighing a person's weight on the ground with only one foot on the ground and placing only one foot on the weight scale. It is a principle.

As such, there is a problem in the conventional gearbox structure that a vehicle driver cannot prevent a vehicle driver from deliberately shifting the vehicle to the left or right side of the gearbox structure so as to reduce the congratulations on the wheels.

Of course, increasing the length of the measuring pad can be considered to solve this problem, but in this case, the cost increases.

The present invention has been made to solve the above-mentioned problems, and even if the vehicle driver intentionally biases the vehicle to the left or right side of the axle structure, it is possible to reduce the amount of celebration on each wheel without increasing the length of the measuring pad. It is an object of the present invention to provide a fixed weight lifter capable of detecting the correct weight of a fraudulent vehicle so that it can be prevented and the actual agitation can be detected.

In order to solve this problem, a fixed weight lifter capable of accurately detecting the weight of an illegally entered vehicle is as follows.

Characterized in that.

Here, the central pile and each auxiliary pile is characterized in that the bolt is coupled to the underground frame through a connection frame that is installed in the longitudinal direction of the underground frame along the upper and lower portions of the underground frame.

On the other hand, between the central pile and each auxiliary pile and the measuring pad is characterized in that the buffer pile made of a rubber material each having a predetermined width is further provided.

In the present invention, the fixed weight scaler capable of detecting the accurate weight of the ingress vehicle is a celebration that the vehicle driver intentionally biases the vehicle to the left or right side of the weight scale structure and increases the weight of each wheel without increasing the length of a conventional measuring pad. There is an effect that can prevent in advance to reduce the weight.

This will eventually lead to the effect of securing the product reliability of the stationary crane.
