Description

It is suitable in the middle of single-unit weighing platform installing the overall scale weighing platform that pull bar is spacing

Technical field

This utility model belongs to on-highway motor vehicle car load meter weight weighing apparatus field, is specifically related to one and is suitable in the middle of single-unit weighing platform The overall scale weighing platform that pull bar is spacing is installed.

Background technology

Overall scale, refers to hold the large-scale truck up to more than 20 rice on its weighing platform, and overall scale can realize dynamically Middling speed is weighed.In structure, overall scale is typically made up of 3-6 joint weighing platform, and corresponding weighing platform and weighing platform are up to more than 20 rice.Overall prosthomere The rear end of scale weighing platform mutually overlaps with the front end of deutomerite weighing platform, shares one group of LOAD CELLS.For dynamic middling speed measure whole Body scale, weighing platform reasonable in design, the most firm can realize weighing platform spacing, it is ensured that weighing platform is stable, also ensure that weighing data Middling speed stably gathers.So-called middling speed dynamic weighing, refers to that it is weighed by vehicle when about 18--36km/h speed.Conversion speed Degree unit, the conversion of 18km/h speed is equal to 5 meter per seconds；The conversion of 36km/h speed is equal to 10 meter per seconds.Load-carrying vapour to 150 tons Car, is calculated by momentum formula M*V=F*T, and the momentum of vehicle change is huge.Huge momentum, by the transmission of weighing platform, right The impact force of weighing platform is also huge, calculates according to the T=1 second, and impact force reaches 500 tons.Owing to impact force is huge, therefore to weighing platform Spacing equipment and the spacing basis of foundation ditch propose harsh demand.Traditional weighing platform is spacing--sets up in the front or rear direction of weighing platform Impact head stopping means, test proves, this collision rift weighing platform can vibrate for a long time, has a strong impact on the data acquisition of LOAD CELLS Collection, does not the most adapt to the demand that middling speed is measured.Middling speed dynamic weighing is measured needs new technical scheme.By " flagpole is in wind Of short duration waving, flagpole is the shortest, and flagpole is the thickest, waves the least " inspiration, technical thought of the present utility model is that " spacing, two is not Interline comes, and limit pull rod before or after installing in the middle of weighing platform, one end of pull bar is at weighing platform, and the other end is on realizing middle limiting platform Support ".In the middle of this utility model independence weighing platform, simplex pull rod stopping means is " during the patent No. 2016208234242 is adapted to fit Between the spacing car load weighing platform foundation ditch of pull bar " on the basis of, the application scheme that technology extends.

Utility model content

According to the technical solution of the utility model, " weighing platform is spacing, and two not interline comes；Before installing in the middle of the weighing platform or Rear limit pull rod, one end of pull bar is at weighing platform, other end support on realizing middle limiting platform ", it is suitable for peace in the middle of single-unit weighing platform The overall scale weighing platform that dress pull bar is spacing, including, the spill entirety scale weighing platform foundation ditch that screw thread steel steel framework body cement is cast-in-place, first segment The limited support welded on the limiting platform of the left and right sides in the middle of the limiting platform of the left and right sides, first segment weighing platform in the middle of weighing platform, The front or rear position-limiting ear of first segment weighing platform both sides, the front or rear limit pull rod of first segment weighing platform both sides, left in the middle of second section weighing platform The limiting platform of right both sides, the limited support welded on the limiting platform of the left and right sides in the middle of second section weighing platform, second section weighing platform The front or rear position-limiting ear of both sides, the front or rear limit pull rod of second section weighing platform both sides,----, the left and right sides in the middle of N joint weighing platform Limiting platform, N joint weighing platform in the middle of the left and right sides limiting platform on welding limited support, N joint weighing platform both sides before Position-limiting ear after or, the front or rear limit pull rod of N joint weighing platform both sides, it is characterized in that, at the two of integral scale table all single-units weighing platform Side, is all provided with front or rear position-limiting ear, and corresponding weighing platform foundation ditch position is provided with realizing middle limiting platform in the middle of the single-unit weighing platform, in Between welded limited support on limiting stand；One end of front or rear limit pull rod is mechanically connected the front or rear position-limiting ear of weighing platform both sides, The other end is mechanically connected the limited support of welding on weighing platform base realizing middle limiting platform；All limit pull rods all use 30 screw rods；Its Joint number N=3-6 of middle weighing platform.

Operation principle of the present utility model is sketched: analog references thinking: flagpole is of short duration in wind to wave, and flagpole is the shortest, shakes Amplitude of oscillation degree is the least；Flagpole is the thickest, and rocking tendency is the least.Base realizing middle limiting platform is just equal to flagpole, and realizing middle limiting platform surface is used It is fixed on the spill weighing platform base that screw-thread steel framework cement is cast-in-place with framework of steel reinforcement cement is cast-in-place inside steel plate, realizing middle limiting platform The length of side of regular prism is more than 600 millimeters, and realizing middle limiting platform is only above spill weighing platform base 230 millimeters, the limited support weldering of both sides It is connected on the steel plate of realizing middle limiting platform.Theoretical Calculation, realizing middle limiting platform can bear the shock of 500 ton forces.Weighing platform is spacing is scale Platform, by the position-limiting ear of both sides, limit pull rod, limited support, is delivered to weight impact force huge--screw-thread steel framework cement On cast-in-place spill weighing platform base, it is ensured that the stability of weighing platform；The method of this weighing platform realizing middle limiting, it is adaptable to overall scale is dynamic Weigh.Compared with traditional overall scale weighing platform, this utility model is suitable in the middle of single-unit weighing platform installing the overall scale that pull bar is spacing The special feature of weighing platform, is two side positions of all single-unit weighing platforms at integral scale table, is all provided with front or rear position-limiting ear, Weighing platform foundation ditch position corresponding in the middle of single-unit weighing platform is provided with realizing middle limiting platform, has welded limited support on realizing middle limiting platform； Weighing platform is spacing, and one end of front or rear limit pull rod is mechanically connected the front or rear position-limiting ear of weighing platform both sides, and the other end is mechanically connected The limited support of welding on realizing middle limiting platform on weighing platform base.

Usefulness of the present utility model is to solve overall scale weighing platform to cause longitudinal spacing of weighing platform because of variations in temperature The problem of gap change, it is not necessary to by seasonal adjustment gap.After intermediate draw bar is spacing, weighing platform is stable, and weighing data gathers quick.In Between pull bar spacing after, weighing platform has rainwater-proof float function.
