Abstract

The utility model provides a balance type weighing device which can solve the technical problem that an existing multi-sensor weighing device is poor in weighing accuracy. The utility model provides a balanced type weighing device, includes and weighs seat, weighing sensor and base, both ends support on the base through a set of weighing sensor respectively around the bottom of weighing seat, and every weighing sensor's of group quantity is 2, its characterized in that: the device also comprises a pin shaft support, a pin shaft support is respectively arranged between each group of weighing sensors, the upper end of the pin shaft support is fixedly connected with the weighing seat, and the lower end of the pin shaft support is rotatably connected with the base. Because the focus of the article of being weighed is in the intermediate position of the article of being weighed, putting on power when being weighed article one side, the strong point of ladle promptly and the article focus of being weighed do not coincide in vertical direction, the article of being weighed, the jar seat deflects to the opposite side around the center pin under the effect of round pin axle support, realize balancing, guarantee 4 sensors evenly atress simultaneously, detect the accuracy height.

Description

Balanced weighing device

Technical Field

The utility model relates to the technical field of weighing devices, in particular to a balance type weighing device.

Background

The weighing device mainly comprises a weighing seat, a sensor and a base. When the weight of the weighed object is large, two groups of weighing sensors are generally arranged between the weighing seat and the base, one group is arranged on each of two sides, and two groups are arranged. However, when the weighed object is placed with deviation or the weighed object and the contact surface of the weighing seat are subjected to deviation, four weighing sensors cannot be uniformly stressed at the same time, and sometimes only 3 or even 2 weighing sensors are stressed, so that the weighing accuracy is poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a balanced weighing device, which can solve the technical problem of poor weighing accuracy of the conventional multi-sensor weighing device.

Its technical scheme is such, a balanced type weighing device, including weighing seat, weighing sensor and base, both ends support on the base through a set of weighing sensor respectively around weighing seat's the bottom, and the quantity of every weighing sensor of group is 2, its characterized in that: the device also comprises a pin shaft support, wherein a pin shaft support is arranged between each group of weighing sensors, the upper end of each pin shaft support is fixedly connected with the weighing seat, and the lower end of each pin shaft support is rotatably connected with the base through a center pin.

Further, the balance type weighing device is installed on the transfer device, and the base is a base of the transfer device.

Furthermore, the left side and the right side of the weighing seat are respectively provided with a connecting seat, and a vertical limiting mechanism is arranged between each connecting seat and the base.

Further, perpendicular stop gear includes last stopper seat, lower stopper seat and spacer pin, go up the stopper seat install in the connecting seat bottom, it is equipped with downwardly extending's limiting plate to go up the stopper seat, lower stopper seat install in on the base, lower stopper seat is equipped with opening constant head tank up, the both sides wall of constant head tank is equipped with the waist shape hole of vertical extension, the limiting plate inserts in the constant head tank, the spacer pin runs through the limiting plate with the waist shape hole of the both sides wall of constant head tank.

According to the balance type weighing device, when weighing is carried out, because the gravity center of the weighed object is located in the middle of the weighed object, when one side of the weighed object is stressed, namely the supporting point of the ladle and the gravity center of the weighed object are not overlapped in the vertical direction, the weighed object and the tank seat deflect towards the other side around the central pin under the action of the pin shaft bracket, balance is realized, the 4 sensors are guaranteed to be uniformly stressed at the same time, and the detection accuracy is high.

Detailed Description

As shown in fig. 1 and fig. 2, a balanced type weighing device, including weighing seat 1, weighing sensor 3, base 2, round pin axle support 4 and center pin, both ends support on base 2 through a set of weighing sensor 3 respectively around weighing seat 1's bottom, the quantity of every group weighing sensor 3 is 2, it is specific, weighing sensor 3 installs on base 2, weighing sensor's response end and the bottom contact of weighing seat 1, respectively be equipped with a round pin axle support 4 between two weighing sensor 3 of every group weighing sensor, the upper end and the weighing seat 1 fixed connection of round pin axle support 4, its lower extreme is rotated through center pin 5 and base 2 and is connected.

The balance type weighing device is arranged on the transfer device, and the base 2 is the base 2 of the transfer device and can be used for weighing the molten steel tank.

Connecting seats 7 are respectively installed at four corners of the weighing seat 1, a vertical limiting mechanism 6 is arranged between each connecting seat 7 and the base 2, and the vertical limiting mechanism 6 is located on the outer side of the weighing sensor 3. Perpendicular stop gear 6 includes last spacing seat, spacing seat and spacer pin down, it includes upper substrate 61 and limiting plate 62 to go up the spacing seat, upper substrate 61 installs in connecting seat 7 bottom, limiting plate 62 installs in upper substrate 61 lower part and downwardly extending, lower spacing seat includes infrabasal plate 63 and locating plate 64, infrabasal plate 63 installs on base 2, a pair of locating plate 64 parallel mount is on infrabasal plate 63 and form opening constant head tank 65 up, locating plate 64 is equipped with vertical extension's waist shape hole 66, the limiting plate inserts in the constant head tank, the spacer pin runs through the waist shape hole of limiting plate 62 and a pair of locating plate 64. The weighing seat 1 is vertically limited through the matching of the limiting pin and the waist-shaped hole, so that the weighing seat 1 is prevented from being excessively pressed down to damage the weighing sensor 3 during weighing; on the other hand, the overturning angle of the weighing seat 1 is limited, so that the weighing seat can be ensured to be overturned towards the other side in a balanced manner relative to the initial acting force under the action of the gravity center of the weighed object.
