Description

Overall weight scale platform laser diffusion intelligent guidance system

Technical field

This utility model belongs to highway automobile meter weight weighing apparatus field and in particular to a kind of overall weight scale platform laser overflows Reflection intelligent guidance system.

Background technology

Known overall scale weighing platform, is all connect by the rectangular platform section column in series of several steels and forms.Single overall scale , between 4-6 rice, entirely the total length of overall scale weighing platform is between 17-25 rice for the length of weighing platform section.Every section of overall scale weighing platform Under corner, support type LOAD CELLS is set, vacantly on LOAD CELLS, this LOAD CELLS does not position overall scale weighing platform. Reached after overall scale weighing platform by weight vehicle, LOAD CELLS obtains the weight of this vehicle.In the both sides of overall scale weighing platform, arrange The anti-ridge that is close to of highly 20 millimeters of inverted V-shaped steel.There is a very big defect in such overall scale weighing platform, be afraid of weighing platform vibrations Topple.Once weight vehicle is close to, it is pressed onto the anti-ridge that is close to of inverted V-shaped steel, the power of vehicle and gravity can resolve into lateral torsion Torque is so that whole weighing platform laterally rocks, or even reversion is toppled.Even some weak vibrations, overall scale scale all can be caused LOAD CELLS displacement under platform, leads to count weight extremely.Vehicle is close to, and single wheel is pressed onto the anti-friction of the inverted V-shaped steel of weighing platform The consequence on the side ridge, gently then counts weight error and increases, heavy then weighing platform topples, and does not work, and stops meter weight！Solution is to need again Sling overall scale weighing platform, reset the LOAD CELLS under weighing platform, adjustment updates meter tuple evidence, could recover use.Prevent Weight vehicle weighing platform is close to becomes a technical barrier.Same technical barrier, solves the patent that weight vehicle weighing platform is close to 2016201541230 (preventions weight vehicle weighing platform be close to alarm set) and 2016201889116 (anti-weight vehicle weighing platform is close to Light to guide article deviation-rectifying system), the former is mechanical collision prompting, and the latter is only weighing platform front end guidance, is all drawing in weighing platform front end Deviation-rectifying system device is provided with road section, does not all address how setting light deviation-rectifying system dress on the weighing platform that steel plate manufactures Put.The road body of the approach road section of weighing platform front end is cement concrete, and concrete is insulator, can arbitrarily bore and dig.Weighing platform is in itself Girder steel plate platform, girder steel plate platform is electric conductor, and in girder steel plate platform, boring mounted lamp is difficult, therefore installs guiding Lamp difficulty is very big.How in the girder steel plate platform of weighing platform, guiding lamp to be installed, allow the light fixture guiding that actively lights be this technology hardly possible The emphasis of topic.For solving above-mentioned technical problem, this utility model entirety weight scale platform laser diffusion intelligent guidance system technology Scheme is, " center guides, and both sides monitor "." center guiding " is to replace light fixture with the diffuse-reflectance refractive body passively lighting, and lights Guiding tested vehicle, travels at weighing platform center all the time, specifically using across the door font portal frame in overall scale weighing platform, in dragon Door frame intermediate lateral hangs installs motor, and motor turning arm is installed laser pen, and laser pen points to track and weighing platform Center.In the center in track and weighing platform, interval setting string diffuse-reflectance refractive body., from eminence irradiation, diffuse-reflectance is anti-for laser Body of light passively luminous formation center guiding light belt；In addition, " both sides supervision " is close to induction coil in track both sides setting electromagnetism, If automotive run-off-road center, both sides electromagnetism is uneven close to induction coil, and sound horn prompting vehicle operator makes vehicle Between two parties, vehicle is prevented to be close to the technical failure causing in weighing platform.
