Abstract
The utility model relates to a steel-ball roof-hitting-type dynamic vehicle axle weight scale limit device, which consists of two steel-ball roof-hitting-type limit mechanisms 3, 4 that are respectively arranged on two sides of a weighing platform 1, wherein, the steel-ball roof-hitting-type limit mechanisms are provided with a door-shaped bracket, the door-shaped bracket is firmly arranged on the weighing platform 1, a horizontal limit head of a weighing platform is arranged on a crossarm of the door-shaped bracket, a longitudinal limit head of the weighing platform is arranged on two vertical supports of the door-shaped bracket, and a steel-ball limit body that is fixed on the ground is arranged inside a space that is formed by the crossarm and the vertical supports of the door-shaped bracket. The spherical-surface contact is adopted between the limit head and the limit body of the limit device, when the weighing platform is under the effect of the horizontal impact force of the vehicle, the vertical friction between the weighing platform and the limit device is greatly reduced, the influence on the weighing precision is far less than that of the prior limit device, thereby improving the weighing precision.
Description
Technical field
The utility model relates to a kind of dynamic vehicle axle stop means that heavily weighs, and particularly a kind of steel ball hits the top formula dynamic vehicle axle stop means that heavily weighs.
Background technology
The road vehicle dynamic weighing is meant that vehicle heavily weighs by axle and weighs under the state that does not stop, vehicle is during by weighing unit, and weighing instrument is measured each weight of vehicle successively, and then each weight is added up, and promptly draws complete vehicle weight.When vehicle dynamic is passed through weighing unit, owing to rub between wheel and the weighing unit, vehicle can produce bigger horizontal impact power to weighing unit, for preventing weighing unit bigger horizontal and vertical displacement takes place under the effect of vehicle horizontal impact power, is provided with stop means in the weighing unit both sides.At present, a kind of steel ball commonly used hits top formula stop means as shown in Figure 6, it spacing 21 and limit body 22 between be sphere and plane contact.When vehicle passes through weighing unit, stop means carry out level spacing in, also can be subjected to the effect of vehicle gravity, can produce friction force upwards between weighing unit and the stop means thus, this friction force can be added on the weighing-up wave, thereby causes the inaccurate of weighing, the sphere of stop means and contacting of plane are arranged, its vertical friction force is bigger, not only influences weighing precision, but also occurs the steel ball stuck phenomenon easily.In addition, if weighing unit is installed on the road surface in ramp, weighing unit is when being subjected to the effect of vehicle horizontal impact power, also can produce a component at the left oblique or right tilted direction of weighing unit, thereby make weighing unit left side pendulum or right pendulum, in this case, need weighing unit to have auto-reset function, but existing stop means is difficult to automatically reset.
The utility model content
The purpose of this utility model is at the problem in the prior art, a kind of improved dynamic vehicle axle stop means that heavily weighs is provided,, improves the check weighing precision to reduce the vertical friction force between weighing unit and the stop means, secondly, can automatically reset during the left and right swing of the weighing unit that the hillside fields is installed.
For achieving the above object, the technical solution of the utility model is as follows:
It hits top formula position-limit mechanism by two cover steel balls and forms, this two covers position-limit mechanism is installed in the both sides of weighing unit respectively, it improves structure: described steel ball hits top formula position-limit mechanism and has a ∏ shape frame, this ∏ shape frame is fixedly mounted on the weighing unit, the cross spacing head of a weighing unit is installed on the crossbearer of this ∏ shape frame, on two perpendicular framves of ∏ shape frame, weighing unit longitudinal spacing head is housed, the end face of described spacing head is a sphere, in the space that the crossbearer and the perpendicular frame of ∏ shape frame surrounds, be provided with a steel ball limit body that is fixed on ground, this steel ball limit body has a steel ball seat, and the position, top of hitting corresponding to horizontal and vertical spacing head on this steel ball seat studs with steel ball structure.
The further improvement project of the utility model is:
Pairing the hitting of described cross spacing head is provided with a disk spring in the steel ball structure of top.
By technique scheme as can be seen, adopt sphere to contact between the spacing head of this stop means and the limit body, friction between them is that (coefficient of rolling friction is 0.05 in rolling friction, the planar friction coefficient is 0.15), be subjected at weighing unit under the effect of vehicle horizontal impact power, its weighing unit can reduce several times with vertical friction force between the stop means, therefore, it is more much smaller than the sphere and the plane contact of existing stop means to the influence of weighing precision, thereby has improved weighing precision.Because this stop means is provided with a butterfly spring below the cross spacing steel ball, make weighing unit when the left pendulum of horizontal stroke can rightly be put, have auto-reset function.

Embodiment
Referring to Fig. 1, the weighing unit that described dynamic vehicle axle heavily weighs comprises weighing unit 1, is embedded in the weighing unit framework 2 on ground, and weighing unit 1 can be movable slightly in weighing unit framework 2, is provided with four LOAD CELLS below weighing unit 1.This stop means hits top formula position- limit mechanism 3,4 by two cover steel balls to be formed, and this two covers position-limit mechanism is installed in the both sides of weighing unit 1 respectively.
Referring to Fig. 2～4, described steel ball hits top formula position-limit mechanism and has a ∏ shape frame 5, this ∏ shape frame is fixed on by securing member 10 on the side plate of weighing unit 1, in order to strengthen the intensity of ∏ shape frame 5, is provided with stiffening plate 5-4 between two perpendicular frame 5-2,5-3 outsides of ∏ shape frame and crossbearer 5-1.The cross spacing head 6 of a weighing unit is installed on the crossbearer 5-1 of this ∏ shape frame, the longitudinal spacing head 7,8 of weighing unit is installed respectively on two perpendicular frame 5-2,5-3 of ∏ shape frame 5, described spacing 6,7,8 end face are sphere; After adjust the position of spacing head, fixing with set nut 19 respectively, for the sake of assurance, can reinforce with holding screw 20 again; Surround at the crossbearer of ∏ shape frame and perpendicular frame and to be provided with a steel ball limit body 9 in the space, this steel ball limit body is fixed on the embedded board 2 by securing member 11, and this embedded board and weighing unit framework are integrally welded.
