Description

Combination side-by-side bent plate axle weight scale

Technical field

The utility model relates to a kind of combination side-by-side bent plate axle weight scale.

Background technology

In management domain is transfinited in highway weight metering charging and improvement; All need weigh to passing vehicle; So that the weight data of vehicle is provided for the weight metering charging and the management of transfiniting; At present the highway weight metering charging detects in the product of weighing with transfiniting since dynamic shaft heavily the mode of the weighing efficient of weighing is high and extensively be used.

Dynamic shaft is heavily weighed in the product, and a kind of is the gravity measure device of weighing platform formula structure, and another kind of is the gravity measure device of traditional bent plate sensor construction.The gravity measure device of weighing platform formula structure adopts the monolithic weighing platform to be covered with the track; It is made up of the tactic pattern of orthodox cars such as weighing platform, LOAD CELLS, framework weighing apparatus; Its advantage is: weighing accuracy is high, maintenance cost is low, and its shortcoming is: the excavation workload is big during installation, long construction period; Can't accomplish the waterproof sand control, need regularly foundation pit to be cleared up that frequency of maintenance is higher.The bent plate sensor alternative arrangement of gravity measure device employing more than 2 of tradition bended plate type structure is on the track; In force bearing plate, LOAD CELLS and force bearing plate form inseparable integral body the foil gauge collection of induction weight for it, and its advantage is: easy for installation; The installation cycle is short; Less maintenance in the use, its shortcoming is: the dynamic weighing precision is not high, the unbalance loading poor performance.

Summary of the invention

The purpose of the utility model just provides a kind of easy for installation, maintenance cost is low, the dynamic weighing precision is high combination side-by-side bent plate axle weight scale.

The combination side-by-side bent plate axle weight scale of the utility model is made up of two weighing platforms of installing side by side, and weighing platform comprises framework, scale body, LOAD CELLS, limited post, Limit Bearing; Framework is made up of horizontal riser, vertical riser and base plate, and framework is provided with drainpipe, penetration pipe, and the scale body is formed by monolithic construction steel or carbon steel metalworking; No pad can improve the strength and stiffness of scale body, has maintenance adjustment hole and spacing hole on the scale body; On adjustment hole and the spacing hole cover plate is set, LOAD CELLS is installed at four jiaos of places of framework, and the sensor pressure bearing head is through being bolted to scale body bottom; The sensor pressure bearing head is pressed on the LOAD CELLS, lives the scale body by sensor support, and sensor signal lines is drawn from penetration pipe; Middle part, framework both sides is equipped with limited post through bolt; The screw thread of limited post upper end is equipped with nut, and nut is fixed framework and scale body, and Limit Bearing is placed in the spacing hole of scale body the spacing usefulness as the scale body; Have seal groove around the scale body, lay seal and fluid sealant in the gap between framework and scale body.

The combination side-by-side bent plate axle weight scale of the utility model has following characteristics with present compared with techniques:

1, on a track, arranges two weighing platforms of installing side by side, can reduce the height of weighing platform greatly, shorten the installation period of equipment, reduce construction volume; 2, the scale body adopts monoblock type high-quality structural steel or carbon steel metalworking to form, and no pad can improve the strength and stiffness of scale body, and the raising of rigidity has the weighing precision that utilizes the raising gravity measure device; 3, scale body and framework all-sealed structure, the silt particle on the track can not get into scale inside, therefore need not to do daily maintenance; 4, adopt self-aligning bearing spacing between scale body and framework; Spacing gap is the play of bearing; Therefore can realize that reliably zero is spacing, and spacing gap is can be because of assembler and maintainer's technical merit not different and change, and has therefore improved greatly yet and has assembled and adjust efficient; 5, each parts of the utility model adopt fabricated structure, and each parts all can independently be changed, and damage the problem with regard to the high maintenance cost of necessary integral replacing in case solved bended plate type gravity measure device sensor; 6, the existing traditional bent plate of the utility model is light small and exquisite, has the high precision of weighing platform formula WT-MSR again concurrently.
