2. The utility model discloses a theory of operation and beneficial effect thereof

(1) When non-overweight vehicles pass through at ordinary times, the vehicle weight does not reach the weight limit standard, the balance of the road surface weight limit mechanism cannot be broken, and the vehicles can smoothly pass through the bearing plate; when the overweight vehicle passes through, when the gravity center of the overweight vehicle reaches the center of the bearing plate, according to the lever principle, the total weight of the overweight vehicle and the weight of the carried goods is averagely decomposed on the pivots at the four corners of the bearing plate, namely, at the moment, two hanging short columns at the two ends of a cross beam at the outlet end of the bearing plate are the same as two bearing short columns at the two corners of the inlet end of the bearing plate, the respective gravity borne by the two hanging short columns is 1/4 of the total weight of the goods, at the moment, the total weight of the overweight vehicle borne by the hanging short columns at the two ends of the cross beam at the outlet end of the bearing plate is transmitted to the road weight limiting mechanism through the hanging connecting rod, and the balance of the road weight limiting mechanism is broken because the total weight of the overweight vehicle exceeds the preset bearing limit of the road weight mechanism, so that the weight limiting block is tilted away from the ground by the weighing lever, at the moment, the weight limiting mechanism resets under the action of the gravity of the weight limiting block, and the bearing plate is level with the road surface again; (see FIG. 9 and FIG. 10)

(2) The transverse groove at the head part of the groove and the cross beam at the head part of the bearing plate are both longer than the width of the overweight vehicle, so that the weight limiting mechanisms arranged at the rear sides of the two ends of the transverse groove are prevented from being scraped when the overweight vehicle passes through the transverse groove;

(3) the two vertical rods of the travel limiting stop lever are designed to be in a staggered step shape, so that the bearing plate and the travel limiting stop lever can be ensured to be flush with the road surface, the travel limiting stop lever is driven to tilt up by pressing down the bearing plate, the structure is simple, normal passing of vehicles is not influenced, and overweight vehicles can be prevented from passing through;

(4) when the overweight vehicle passes through, the output end of the bearing plate moves downwards, the damping material is laid at the bottom of the groove, meanwhile, the gravity of the limited weight block reversely controls the weight of the overweight vehicle through the lever system, and in addition, the free fall of the overweight vehicle is not more than 10cm, so that large vibration cannot be caused, and the overweight vehicle and the groove cannot be damaged;

(5) the anti-skid racks on the top surface of the bearing plate can effectively prevent tires from skidding, ensure that vehicles normally run through and overweight vehicles smoothly back and exit from the inclined bearing plate;

(6) damping materials are laid on the road surface at the bottom of the weight limiting block to prevent the weight limiting block from impacting and damaging the road surface due to up-down movement, and baffles are arranged on two sides to prevent the weight limiting block from swinging left and right when moving up and down;

(7) the metal cover is arranged outside the weight limiting mechanism, so that the weight limiting mechanism is rainproof and dustproof, is not damaged by external force, and prolongs the service life of the weight limiting mechanism;

(8) the driving of the vehicle is limited, the vehicle is completely pressed on the bearing plate, partial tires are prevented from being pressed on the road surface to share the weight of the vehicle, and the entrance of the limiting track is splayed, so that the bearing plate on the vehicle is conveniently guided;

(9) the deceleration strip is arranged at the groove entrance end, so that the vehicle is decelerated to enter the bearing plate, and the phenomenon of punching and clamping is prevented.

Detailed Description

(1) The outer side distance of the tire on the outer side of the weight-limiting vehicle is generally 2.5m, so that the width of the groove is 3m, the width of the bearing plate can be ensured to be 48cm wider than the outer side distance of the tire on the outer side of the weight-limiting vehicle under the condition that the width of the bearing plate is 2cm narrower than the groove, and the tire on the outer side of the weight-limiting vehicle can be completely pressed on the bearing plate; the length of the groove is slightly longer than the total length of the weight-limiting vehicle, because the distance from the front end of the vehicle head of the weight-limiting vehicle to the landing point of the front tire is generally about 0.9m, and the distance from the rear end of the vehicle tail to the landing point of the rear tire is about 1m, because the center of gravity of the weight-limiting vehicle is deviated from the middle of the vehicle, when the vehicle head exceeds the bearing plate and the front tire reaches the position near the outlet end of the bearing plate, the center of gravity of the weight-limiting vehicle just reaches the center of the bearing plate, so that the weight-limiting mechanism is excited to change the balance state. Accordingly, the height of the vehicle driving limiting stop lever at the outlet end of the groove after being tilted is preferably 30-35cm, and the vehicle head is prevented from being damaged by the tilting of the driving limiting stop lever. The longest multi-axle trailer of the truck in China is generally 16.5m, and only a few vehicles exceed the length, so that the device can be installed on a road bridge of the multi-axle trailer, and the length of a groove is preferably 17.5 m. The length of the non-trailer truck is generally 11.5m, so the device is installed on other roads, and the length of the groove is preferably 12 m.

(2) When the weight limiter is installed on the single-way road or the bridge section of the double-way road with obstacles in the middle, the left and right residual road surfaces are required to be provided with obstacles, so that overweight vehicles can not pass through the weight limiter. When the weight limiting device is installed on the road bridge section with four lanes and more than four lanes in two directions, the weight limiting device on each lane is installed in parallel when the right-going foundation has enough width; when the width of the right-hand ground is limited, the weight limiting device on each lane is installed in a staggered mode.

The above embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
