SU32181A1 - Platform scales - Google Patents

Description

The invention also relates to a platform scale equipped with swinging pads, a pull ending in a three-tooth suspension and a scale running along the entire length of the rocker arm.

In the proposed weights, in order to give them full swing freedom and eliminate the displacement of prisms from their seats during shocks, the sub-platform straight arm is connected to the shoulders of two equal-arm transverse rockers oscillating on the prisms, and the remote shoulders of these levers are connected to the platform supporting frame.

In FIG. 1 shows a vertical longitudinal section of a platform scale according to AA in FIG. 2; FIG. 2 is a cross-section through BB of FIG. Ij of FIG. 3 is a top view of them on the platform; FIG. 4-cross section of them in the GG of FIG. 3

The balance arm is connected by means of gi / P with three-hinged suspension 20, on the upper teeth of which are put on the shackles of the transverse levers 23, which carry two ends 24 at each end, 27 and the shackles 25 fastened at the bottom of the longitudinal bars 26 of the supporting frame the platforms / 5, and the earrings 27 are suspended on the pins mounted in the shield 28 of the scale frame. On

396

the lower tooth of the hanger 20 is put on the ring 2J of the link 22, which is connected with the direct sub-platform lever 9, which imparts stability to the transverse arms 23. The other end of the lever 9 is connected with two equal-arm rocker arms 31, oscillating on the prisms 8, which are supported by their pointed on earrings 3 pillows /, which earrings are suspended on prisms 6 to brackets 33. The remote ends of the arms of the rocker arms 3 are connected by earrings 30 with longitudinal bars 26 of the supporting frame of the 7J platform, and nearby ones with a sub platform platform 9 bearing the prism 8. After On its bottom it rests on flat pads 7 placed in earrings 32 suspended from the arms of the rocker arms 31.

Thus, the weighing platform has four points of support, which should inform it of complete swing and eliminate the possibility of prisms moving from their positions during shocks.

The subject matter of the invention.

Platform scales, equipped with swinging pads, a traction ending with a three-tooth suspension, and a scale running along the entire length of the rocker arm, characterized by use, in order to give the platform scale full freedom to swing and eliminate the displacement of prisms from their places during tremors, two

equal-shoulder transverse rocker arms 3t, oscillating on prisms 8 and connected by distant ends of the shoulders to the base frame of the platform, and nearby ends to the sub-platform straight lever 9 (Fig. 1-4)
