Abstract

The utility model relates to a hook head type electronic balance, which is an electronic weighing and measuring device. The existing hook head suspended type electronic hanging balance can weigh and measure after hung on the hanging hook of a crane. Thereby, the using height of the original design of hoisting equipment is limited; the operation is very inconvenient; the using range is narrow. The utility model is provided with a sensor on a cross beam above the hanging hook of the crane; the sensor can be a cirque type resistance strain sensor which is positioned at the center of the upper part of the cross beam, and can also be a bridge type resistance strain sensor which is positioned at the two sides of the cross beam. The utility model has the advantages of reasonable and simple structural design, broad using ranges, low cost, etc.

Description

Gib head formula electronic scales

The utility model relates to a kind of electronic-weighing measuring apparatus, particularly a kind of gib head formula electronic scales, and it mainly is applicable to the Weighing of departments such as harbour, station, warehouse.

The structure of gib head suspension type electronic crane scale of the prior art as shown in Figure 1, it by steelyard hook 1 ', electronic crane scale body 2 ', coupling shaft 3 ' and steelyard link 4 ' composition, electronic crane scale body 2 ' comprise instrument box wherein, Sensor box and battery, during use, steelyard must hang over the suspension hook 5 ' following ability Weighing of crane, and crane running block 9 ', side plate 8 ', back of the body cap 7 ' and crossbeam 6 ' then the be parts on the existing crane, so hang the former design use height that metering has limited hoisting device, at present harbour, in the actual use in warehouse and workshop, the piling height and the storehouse capacity of goods have been influenced, also very inconvenience is dwindled existing gib head suspension type electronic crane scale usable range when weighing is measured in the operation.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, does not influence the gib head formula electronic scales that former rubber tyre gantry crane design is used height.

The purpose that the utility model proposed can be achieved through the following technical solutions: the crossbeam above the crane hook is provided with resistance strain type sensor, this sensor can be a garden ring type resistance strain type sensor, it is positioned at the center upper portion of crossbeam, also can be the bridge-type resistance strain sensor, it be positioned at the both sides of crossbeam.

Description of drawings is as follows:

Fig. 1 is the structural representation of existing gib head suspension type electronic crane scale.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is an I enlarged drawing of the present utility model.

Fig. 4 is an another kind of structural representation of the present utility model.

Fig. 5 is the sensor construction synoptic diagram that is installed in the crossbeam both sides.

Fig. 6 is the synoptic diagram of the utility model extension instrument case.

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Embodiment one:

Referring to Fig. 2, Fig. 3, this electronic scales mainly is made up of whip-gin group 9, side plate 8, back of the body cap 7, crossbeam 6, suspension hook 5 and garden ring type resistance strain sensor 10, suspension hook 5 is fastenedly connected with back of the body cap 7, side plate 8 is positioned at the both sides of crossbeam 6, garden ring type resistance strain sensor 10 is then between crossbeam 6 and back of the body cap 7, instrument box 11 can be installed in respectively on the side plate 8, also can be installed on the side side plate 8.The bottom of garden ring type resistance strain sensor 10 its elastic bodys 13 and overcoat 14 close-fittings in the present embodiment, following of elastic body 13 upper end supporting plane bearings 15, protective cover 12 all has certain interval with ring type resistance strain sensor 10 upper ends, garden and surface bearing 15, and 16 is O-ring seal; Garden ring type resistance strain sensor 10 snaps in the center upper portion of crossbeam 6, and crossbeam 6 is as the bearing of LOAD CELLS, after suspension hook 5 is fastenedly connected with back of the body cap 7,, and can freely rotate on garden ring type resistance strain sensor 10 by surface bearing 15 relative fixed.

When the needs Weighing, to be claimed that thing hangs on the suspension hook 5, the wire rope of crane is sling weighing article through pulley blocks 9, back of the body cap 7, surface bearing 15 that the weight process and the suspension hook 5 of weighing article is fastenedly connected, directly be pressed on the sensor elastomer 13 that is fixed on the crossbeam 6, send into instrument box 11 thereby weight is transformed into electric signal by cable, and calculate automatically, handle, finally draw the accurate gravimetric value that is claimed thing.

Embodiment two:

Referring to Fig. 4, Fig. 5, sensor among this embodiment is a bridge-type resistance strain sensor 17, it is positioned at the both sides of crossbeam 6, and be fixed on the side plate 8 by bolt 21, nut 22, keep the gap between side plate 8 and this bridge-type resistance strain sensor 17 to adjust with packing ring 20, being supported at both ends on the bridge-type resistance strain sensor 17 of crossbeam 6, sensor shield 19 usefulness screws 18 are fixing.5 is suspension hook, and 15 is surface bearing, and 7 are back of the body cap.

When carrying out Weighing, claimed that thing hangs on the suspension hook 5, the weight of weighing article is pressed on the bridge-type resistance strain sensor 17 that is fixed in side plate 8 through suspension hook 5 and crossbeam 6, sensor 17 is transformed into electric signal with weight and sends into instrument box 11 by cable, thereby draws the gravimetric value that is claimed thing.

Referring to Fig. 6, instrument box 11 (referring to Fig. 2) also can not be fixed on the side plate 8, and installs at the scene by sensor cable 23 temporarily, and at this, the structure that sensor is positioned at crossbeam 8 both sides is suitable for too.

The utility model compared with prior art has the following advantages: 1, structural design is closed Reason, height is used in the former design that does not affect crane gear, and the scope of application is wide, is particularly useful for Be subjected to limitation in height but must carry out the department of Weighing; 2, simple in structure, the user Just, cost is low, is a kind of Novel weighing metering that replaces present gib head suspension type electronic crane scale Device has preferably social benefit and economic benefit.
