Description
Affiliated technical field
The utility model belongs to the surveying instrument field, is specifically related to a kind of improvement of electronic car weighing platform.
Background technology
Present electronic vehicle weighing apparatus is a kind of kind complexity, the non-standard equipment that structure is various.Most of manufacturers plagiarize design mutually, do not carry out labor, and the structural design defective is more.Following point usually occurs: 1, the sensor support beam is fixedlyed connected with the end shrouding with support main beam by section bar, and latticed with horizontal gusset composition between the support main beam, structure is complicated, the production cost height; 2, in the middle of the sensor position of the fulcrum deflection weighing platform, because of the action of gravity nose, the frequent bump of weight causes sensor to damage fast to weighing platform when crossing heavy duty.
National patent ZL96229040.8 and ZL99228305.1 provide another kind of electronic car weighing platform, comprise panel, support main beam, sensor support beam and end shrouding, panel is positioned at support main beam top and fixedlys connected with support main beam, the sensor support beam is fixedlyed connected with the end shrouding, has adopted U-lag steel support main beam.This is the most rational relatively so far electronic vehicle weighing apparatus scale structure.Because the end shrouding of narrating in this patent structure is section bar, sheet material or its combination, in order to guarantee the rationality of welding technology, its structure must have the sensor support beam, this sensor support beam is connected with the end shrouding outside the shrouding of outstanding end, back, need on panel, open a mouth corresponding to the position of sensor, add a cover little cover plate, and install end cap additional at the two ends that claim body.Its shortcoming is as follows: 1, outside the shrouding of the outstanding end of sensing station, make sensor too small from weighing platform end distance, a large amount of dust stratifications are piled easily to sensor, and the cleaning dust stratification is very inconvenient; 2, end construction is unreasonable, and end position is not only narrow but also long, and for being covered with the weighing platform joint especially, having installed with jack stand, sensor leg in conjunction with the end of many weighing platforms structure, people can't squat and install above weighing platform and the maintenance sensor; 3, complex structure, cover plate is too much; When the construction of the electronic vehicle weighing apparatus ground that foundation ditch is arranged, also need to dig several people's that can squat installation and maintenance hollow place, and then add the cover plate of respective numbers at the relative sensing station in weighing platform both sides; 4, the installation and maintenance space is unreasonable, and the most rational longitudinal spacing and cross spacing space when the weighing platform end has occupied design weighing apparatus cause the stop means complexity, can't on-the-spotly adjust the stop means position, and the weighing apparatus foundation construction is strict.
Summary of the invention
It is more rational that the purpose of this utility model provides a kind of physical construction, both had national patent ZL96229040.8 and ZL99228305.1 electronic car weighing platform and adopted U-lag steel support main beam advantage, and can overcome the raise-free electronic car weighing platform of national patent ZL96229040.8 and ZL99228305.1 electronic vehicle weighing apparatus scale structure defective again.
