The pipeline meausring apparatus
Technical field
The utility model relates to a kind of meausring apparatus that is used for pipeline equipment, when this device descends, charging basket is placed on the platform balance with the weighing charging basket in the weight of material, belong to mechanical manufacturing field.
Background technology
In industries such as rubber manufacturing machinery, chemical industry metallurgicals, adopt the pipeline equipment that automatic batching system is arranged usually at present for improving prescription production efficiency.
Assist on the frame of existing pipeline equipment and be provided with delivery track, normally adopt roller bearing structure or link chain mechanism, charging basket hangs or directly is placed on the delivery track.When charging basket is transported to desired location, by the lifting weighting device that the is provided with platform balance jack-up charging basket that makes progress, after finishing weight of material, weighing falls again, and charging basket is continued to be fed forward to finish down a kind of weighing of material more then.The panel that existing lifting weighting device is mainly promoted by cylinder, and fixing platform balance etc. is partly formed on panel.
Owing to have certain friction between the guide pillar of lifting weighting device and the connection bearing, thereby can in the process of jack-up charging basket that makes progress, shake, the platform balance that causes realizing the weighing operation needs certain stabilization time after rise, the weighing time is long, weighing data is inaccurate, also directly has influence on the efficient of pipeline equipment.In addition, reduced the serviceable life of platform balance.
The utility model content
Pipeline meausring apparatus described in the utility model, its purpose of design is to address the above problem and takes lift frame by air cylinder driven, following general who has surrendered's charging basket by the lift frame is placed on the platform balance, and platform balance need not lifting repeatedly, and need not stabilization time can direct weighing.
For realizing above-mentioned purpose of design, described pipeline meausring apparatus has:
A frame that is interconnected to form by inside and outside support is connected with the pipeline track above frame;
The frame inside that forms at inside and outside support is provided with a weighing framework, in the upper fixed of weighing framework one electronic platform scale is set;
Be that with the difference of prior art a cylinder that is used for the drive chassis lifting is set in the bottom of described frame, and cylinder axis upwards is fixedly connected on the mounting bracket of frame bottom.
Pipeline meausring apparatus as above-mentioned structure, when the carrying material charging basket along the pipeline track, comprise along roller bearing and slide or be suspended on the first-class form of link chain mechanism, and when being transported to the weighing station, promote mounting bracket by cylinder, and then drive frame decline, and charging basket is placed to the upper surface of platform balance from top to bottom, and this moment, weight of material was displayed on platform balance.
After weighing finished, cylinder axis upwards rose to promote frame and rises, and charging basket breaks away from platform balance to certain altitude, and cylinder is out of service, and charging basket continues to be fed forward along the pipeline track, to finish the charging basket weighing of next carrying material.
Be to improve the weighing accuracy, keep charging basket balance quality vertically, further improve feature and be,
Be provided with several guide shafts below described mounting bracket, the bottom of guide shaft penetrates corresponding linear bearing inside respectively, and linear bearing is by being bolted to the frame bottom.
When cylinder axis promote mounting bracket in vertical direction carry out lifting the time, guide shaft reciprocatingly slides along the bearing of linear bearing inside, thereby the guide effect of frame in vertical direction is provided, and makes charging basket can flatly be placed on the platform balance upper surface.
Arriving by the accuracy of weighing station for improve adjusting charging basket, above the inner support of described frame or support arm, an optoelectronic switch being set.
As above content, the advantage that described pipeline meausring apparatus has is, air cylinder driven lift frame and need not to operate platform balance lifting repeatedly can be saved the stabilization time of platform balance and realizes direct weighing, the overall weighing time is short, weighing data is comparatively accurate, is easy to keep the levelness on platform balance surface.
Description of drawings
Fig. 1 is the structural representation of pipeline meausring apparatus.
Fig. 2 is the side schematic view of Fig. 1.
Fig. 3 is bowing to synoptic diagram of Fig. 1.
As shown in Figure 1 to Figure 3, inner support 1, support arm 2, frame 3, pipeline track 4, weighing framework 5, electronic platform scale 6, cylinder 7, mounting bracket 8, guide shaft 9, linear bearing 10, photoelectricity is near switch 11.
Embodiment
Embodiment 1, and as shown in Figure 1 to Figure 3, frame 3 is interconnected and formed by inner support 1, support arm 2, is connected with pipeline track 4 above frame 3, a photoelectricity is set near switch 11 above inner support 1.
Be provided with a weighing framework 5 in frame 3 inside, an electronic platform scale 6 be set in the upper fixed of weighing framework 5;
Be provided with one in the bottom of frame 3 and be used for the cylinder 7 that drive chassis 3 is carried out lifting, cylinder axis upwards is fixedly connected on the mounting bracket 8 of frame 3 bottoms.
Be provided with 4 guide shafts 9 below mounting bracket 8, the bottom of guide shaft 9 penetrates corresponding linear bearing 10 inside respectively, and linear bearing 10 is by being bolted to the bottom of frame 3.
When charging basket when pipeline track 4 arrives the weighing stations, during promptly near optoelectronic switch 11, pipeline track 4 stops, promoting delivery track 4 by cylinder 7 descends, guide shaft 9 along linear bearing 10 to lower slider, thereby the guiding of frame 3 in vertical direction is provided, makes charging basket can flatly be placed on platform balance 6 upper surfaces.
After weighing finished, cylinder axis upwards rose to promote frame 3 and rises, and charging basket breaks away from platform balance 6 to certain altitude, and cylinder 7 is out of service, and charging basket continues to be fed forward along pipeline track 4, to finish the charging basket weighing of next carrying material.
