Description

The wireless data sending electronic scale with hook head

The utility model relates to a kind of crane meausring apparatus, particularly a kind of wireless data sending electronic scale with hook head.

Crane commonly used at present has three kinds of forms with weighing device: 1, sensor is directly installed on the lifting beam with hook, its shortcoming is to utilize original suspension hook group, and the precision of scale also be cannot say for sure to demonstrate,prove.2, adopt electronics sky cart balance, four sensors are installed on the dolly of crane, this method ratio of precision is higher, and shortcoming is installation, safeguards inconvenience that improvement expenses is higher.3, directly adopt general electronic crane scale, be suspended on the suspension hook, this method precision is higher, and dirigibility is good, uses at most.Shortcoming is that suspension height is bigger, and general 20 above steelyard suspension heights all more than 1.2m, have increased the suspension link in addition, and scale body collision probability increases.

The purpose of this utility model provide a kind of measuring accuracy height, suspension height increase less, wireless data sending electronic scale with hook head that improvement cost is low.

The technical scheme that realizes above-mentioned purpose is: a kind of wireless data sending electronic scale with hook head, by suspension hook-transverse beam assembly, two yoke plates, pulley assembly, sensor, sensor axis, the emitter case, battery case and instrument are formed, sensor is installed on the sensor axis, sensor axis is fixedly mounted between two yoke plates, and the two ends of sensor axis have draw-in groove, this draw-in groove cooperates with the clamp in the yoke plate outside, also has a framework, this framework is composed of a fixed connection by top board and biside plate, the top-supported of framework is on sensor, described suspension hook-transverse beam assembly is installed in the bottom of framework, and fixedly connected with the side plate of framework, described emitter case and battery case are installed in the side plate outside of framework respectively.

After adopting technique scheme, former suspension hook-transverse beam assembly on the crane is intactly packed in the framework, sensor is installed on the sensor axis, and pack between two yoke plates with framework, formed reverse frame load mechanism jointly, sensor axis and former suspension hook group two yoke plates are formed upper frame jointly, thereby the increase of this structure suspension height seldom, can also utilize simultaneously yoke plate, the lifting beam with hook assembly of former hook assembly, not only guarantee the high precision of scale but also reduced improvement cost.In addition, the two ends of sensor axis have draw-in groove, and this draw-in groove cooperates with the clamp in the yoke plate outside, can prevent the swing of sensor axis.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the I portion structure enlarged diagram of Fig. 1;

Fig. 3 is the assembling relationship figure of sensor axis and yoke plate among Fig. 1.

As Fig. 1,2, shown in 3, a kind of wireless data sending electronic scale with hook head, by suspension hook-transverse beam assembly 8, two yoke plates 9, pulley assembly 10, pressure type sensor 2, sensor axis 3, emitter case 7, battery case 6 and instrument are formed, pressure type sensor 2 is installed on the sensor axis 3, sensor axis 3 is fixedly mounted between two yoke plates 9, and the two ends of sensor axis 3 have draw-in groove 12, this draw-in groove 12 cooperates with the clamp 11 in yoke plate 9 outsides, also has a framework 1, this framework 1 is composed of a fixed connection by top board 1-1 and biside plate 1-2, the top-supported of framework 1 is on sensor 2, described suspension hook-transverse beam assembly 8 is installed in the bottom of framework 1, and fixedly connected with the side plate 1-2 of framework 1, described emitter case 7 and battery case 6 are installed in the side plate 1-1 outside of framework 1 respectively.

As shown in Figure 2, framework 1 is connected by bolt with side plate 1-2 by top board 1-1, by the seam load, is the detachable type structure.Adopt this structure to be convenient to installation and removal.

As shown in Figure 3, sensor axis 3 is a square shaft.Adopt this structure to be convenient to sensor installation 2 on sensor axis 3.

As shown in Figure 1, also be fixed with stop means on the yoke plate 9.Adopt this structure, when electronic scale with hook head rocks or collided, can prevent that sensor 2 from deviating from framework 1.

The utility model installation process is as follows: former suspension hook-transverse beam assembly 8 is pulled down from former yoke plate 9, intactly pack in the framework 1, form the underframe assembly, pressure type sensor 2 is installed on the sensor axis 3, and and the underframe assembly pack in the lump between two yoke plates 9, limiting plate 5 is fixed on the yoke plate 9, connect sensor, battery cables, emitter case 7 and battery case 6 are respectively fixed on the side plate 1-1 of framework 1, instrument is fixed in hoisting box or other back shop.

Principle of work of the present utility model is as follows: the weight of object acts on sensor 2 by suspension hook, be converted to corresponding analog voltage signal through sensor 2 and send data acquisition board, convert digital signal corresponding to through amplification, filtering, A/D, deliver to the data processing plate of the display instrument of weighing through wireless system for transmitting data, after processing, processing, obtain corresponding weight data, show by digital display screen, this weight data can be exported by serial port, pass through printer prints when needing, send the large screen display demonstration or serve bit machine.

The utility model has reduced the suspension link, has reduced the collision in the work, and metering is convenient, has improved work efficiency, and easy for installation, safe and reliable, the accuracy height can be used as Trade Measures, is suitable for the transformation of cranes such as rail yard, factories and miness and harbour.

The utility model is particularly suitable for the handling goods metering in fields such as rail yard, port and pier, Ferrous Metallurgy, shipbuilding, material storage and transportation, metal transaction, and safety detection etc.
