Problems solved by technology

Since the weighing system uses a group of racks as the weighing platform, the center of gravity of the entire weighing system is high, and the upper and lower parts are difficult to limit, resulting in poor stability and accuracy of the weighing system and a high failure rate.
In addition, during maintenance, due to the narrow working surface in the machine pit, a ladder needs to be erected when adjusting the 2 sets of pull rods on the side of the upper rack, and at least 2 jacks are needed when replacing the load cell at the bottom of the rack, and it is very difficult to adjust the bottom limit screw. Difficult, unsafe operation; maintenance work is labor-intensive, labor-intensive, and time-consuming

Embodiment Construction

[0021] The present invention will be further described below in conjunction with drawings and embodiments.

[0022] like figure 2 , image 3 As shown, a lever-type steel coil online weighing and measuring device is used to fix the weighing platform base 2 with bolts or direct welding on a set of (two) frames 1 on both sides of the guide groove of the walking beam 16 in the production line. Two sets of (two) support frames 4 are arranged longitudinally parallel to the middle position of the weighing platform base 2, and are fixed on the weighing platform base 2 with bolts; A set of inclined weighing table 5 constitutes a "V"-shaped weighing table mechanism in section. In order to strengthen the strength of the inclined weighing table 5, 2 vertical, 2 horizontal and 4 reinforcing ribs are added on the back of the inclined weighing table 5 (in the figure not shown), so that the inclined weighing table 5 will not be deformed. A set of (two) bushings 6 are welded and fixed long...

Abstract

The invention discloses a lever type steel coil on-line weighing metering device. A set of supporting frames are arranged on a weighing platform base, a set of inclined weighing table tops are symmetrically arranged above the supporting frames to form a V-shaped weighing table top mechanism, shaft sleeves are arranged below the inclined weighing table tops, and the shaft sleeves are movably connected with the top portions of the supporting frames. Limiting plates are horizontally fixed on the inner sides of the vertical edges of the lower portions of the inclined weighting table tops, adjusting screws arranged on the lower portions of the limiting plates penetrate through reserving holes in limiting supports on the weighing platform base, and the adjusting screws are movably connected through nuts. A set of weighing sensors are arranged below the flat faces of the inclined weighing table tops, screws on the lower portions of the weighing sensors penetrate through reserving holes in the supporting frames of the weighting platform, and the screws are movably connected through nuts. The weighting sensors are connected with a connecting box and a weighing instrument through cables. The set of inclined weighing table tops which form the V-shaped weighing table top mechanism are designed according to the lever principle, the steel coil on-line weighing metering device is disengaged from a rack, gravity center is low, stability is good, failure rate is reduced and maintaining is convenient.

Description

technical field [0001] The invention relates to a weighing and measuring device for rolled steel coils in the metallurgical industry, in particular to a lever type online weighing and measuring device for steel coils. Background technique [0002] At present, the weighing measurement of cold and hot rolled steel coils in the production line is generally used: 4 load cells are installed at the bottom of the frame on both sides of the walking beam guide groove, and 2 sets of tie rods are installed between the side of the frame and the pit body. , after the position is limited, the steel coil is lifted and supported by the walking beam, and after translation, the steel coil is placed in the "V" groove fixed on the frame for weighing measurement, such as figure 1 shown. figure 1 The height from the medium load cell through the frame to the steel coil to be weighed is more than 3 meters. A group (two) of the racks has a self-weight of about 40 tons, and the weight of the steel c...
