Abstract

The utility model relates to a balancer for a fork-lift truck. The utility model which can be arranged on the fork bracket of the fork-lift truck comprises a power supply, a sensor, a display instrument, an electronic level, etc. The utility model is characterized in that the balancer also comprises a fixing plate and a meter plate which are vertically arranged; the upper end of the pressing-pulling type sensor which is vertically arranged is supported by a support piece which is connected with the fixing plate, and the lower end of the pressing-pulling type sensor is supported by another support piece which is connected with the meter plate; the meter plate is fixed with the angle type fork of the fork-lift truck; the fixing plate is installed on the crossbeam which is arranged on the fork-lift truck and can make the fork bracket move up and down; an energy dissipating spring piece is fixed between the meter plate and the fixing plate horizontally. The utility model has the advantages that the weight of an article can be known when the article is carried by the fork-lift truck; the weighting and transporting are integrated in one program.

Description

Balancer for fork trucks

The utility model relates to a kind of weighing amount device, particularly relates to a kind of meausring apparatus with demonstration, record thing weight that is contained on the fork truck.

When the manufacturing of meeting article finishes or situations generations such as article warehouse-in, shipment, often need article actual measurement net weight or gross weight, the conventional practice is article to be carried to means such as artificial, crane, fork trucks to weigh on platform scale or the on-ground weigher earlier, and then with same approach with article warehouse-ins or shipment, this way is carried and weighed is to be divided into a plurality of steps to carry out, when article were heavy, above-mentioned means were more time-consuming, effort.

This reality do novel purpose provide a kind of during with fork truck carrying article, the Balancer for fork trucks that carrying and weighing amount can be carried out synchronously.

The utility model purpose is to realize like this, promptly design a kind of Balancer for fork trucks that includes power supply, sensor, terminal box, Displaying Meter, electrolevel and be electrically connected mutually that is installed on the fork truck crotch, it also includes vertically disposed fixed head and metering plate, have the upper end of the pressure/pull-type sensing that can experience pulling force or pressure simultaneously of vertical setting to be supported by the rest pad that is connected with fixed head, the lower end is by the rest pad supporting that is connected with metering plate; The angle type crotch of metering plate and fork truck is fixed, and fixed head is installed on the crossbeam that can make the upper and lower mobile fork truck of crotch; There is the power spring leaf of disappearing to be horizontally fixed between metering plate and the fixed head.At pressure/pull-type sensor internal conventional resistance strain plate is housed, when on article are contained in the crotch of fork truck, weighing, the stressed F of crotch, make to draw/experience respective horizontal component FX and vertical stress component FY on the pressure sensor, because the effect of the power spring leaf that disappears is arranged, the power spring leaf is offset so FY is disappeared, the resistance value of the resistance wire in the resistance strain gage only changes with the size of FX, this signal variation is reached Displaying Meter by terminal box, simultaneously, article horizontality information is passed to Displaying Meter synchronously by electrolevel, to show the concrete weight number of article, reach the metering purpose.Be connected in series a printer again as Displaying Meter, then directly can obtain Item Weight data with literature record.

By technique scheme, can be when fork truck be carried article, easy and obtain Item Weight intuitively what are, make a weighing and carrying program that unites two into one, the error strictness that alleged thing is heavy is up to standard, and more general platform scale or the heavy degree of accuracy of ground weigh scale be height.

Give to specify below in conjunction with accompanying drawing:

Design a kind of Balancer for fork trucks that include assembly such as power supply, sensor, terminal box, Displaying Meter, electrolevel and be electrically connected mutually that can be installed on the fork truck crotch (16).Above-mentioned each assembly all can commercially availablely obtain, and novel each assembly of this reality all can adopt (being called for short CAS company) BA type sensor (4), JB-4 type terminal box (13), the BI type Displaying Meter (15) of Kaishi Electronic Co., Ltd., Shanghai's development.CLB-1 type electrolevel (14), electrolevel are used for checking whether the article that are placed on the crotch (16) are in horizontality.For the ease of Balancer for fork trucks is fixed on the fork truck, so design has vertically disposed fixed head (1) and metering plate (2), pressure/pull-type sensor (9) upper end that not only can experience pulling force but also can experience pressure that vertically is provided with is supported by the rest pad that is connected with fixed head (12), the lower end is supported by the rest pad that is connected with metering plate (11), metering plate is fixing with the angle type crotch (16) of fork truck by briquetting (18), fixed head is installed on the crossbeam (7) that can make on the fork truck that crotch moves up and down by contiguous block web members such as (3), by screw (6) tightening, number of sensors is not limit, can decide according to different fork trucks, the utility model pressure/pull-type number of sensors is two, above-mentioned terminal box can be fixed between fixed head and the metering plate, Displaying Meter, electrolevel is fixed on the position of easy observation of fork truck, when article are placed on the crotch, because factors such as pressure/pull sensor esthesis signal principle and Balancer for fork trucks structure decision, pressure/pull-type sensor a horizontal component FX to article gravity,-FX works, and vertical force FY is given to eliminate by the power spring leaf of disappearing from textural.The power spring leaf of disappearing be divided into disappear power spring leaf (7) and under the power spring leaf (10) that disappears all be horizontally fixed between metering plate and the fixed head, and lay respectively at the outside of pressure/pull-type sensing top and bottom, for increasing the rigidity of spring leaf, each spring leaf all uses pressure spring plate (8) to give clamping.For effectively eliminating vertical stress component, the power spring leaf of disappearing can be established a plurality of, and the utility model adopts upper and lower each three.The power spring leaf makes the spring leaf fracture because of the accidental factor of being hit in order to prevent to disappear, even cause damaging pressure/pull-type sensor, so near near the power spring leaf that disappears, be provided with safety piece, its version can be diversified, as with pin, lath etc., the utility model adopts is screw of insuring (4) between supporting fixed head and the metering plate and following screw gate (5) etc.For ease of data recording, so Displaying Meter also can be connected in series printer, power supply can be used the 12V direct current.
