On-line plate blank weighing device

Abstract

The invention relates to an on-line plate blank weighing device, belonging to the technical field of weighing equipment. The on-line plate blank weighing device comprises a weighing platform, a hydraulic oil cylinder, a pressure sensor, a cooling water pipe and a control display device, wherein the weighing platform is positioned in a pit below a roller way; the hydraulic oil cylinder is provided with a piston rod, and the signal input end of the hydraulic oil cylinder and the signal output end of the pressure sensor are respectively connected with corresponding ports of the control display device; at least one pair of supports are respectively installed on terraces on both sides of the roller way, the pressure sensor is fixed on the supports, a connecting frame is arranged on the pressure sensor, the hydraulic oil cylinder is fixed on the connecting frame, one end of the piston rod, extending out of the hydraulic oil cylinder is connected with the weighing platform on which a bracket passing through a gap between rollers on the roller way at intervals is assembled, and a movable arm is arranged between the connecting frame and the supports; and one end of the movable arm is articulated with the supports, and the other end is articulated with the connecting frame. The on-line plate blank weighing device not only can prevent main parts from being rusted to damage, but also is convenient for inspection and maintenance.

Description

technical field

[0001] The invention relates to a device for weighing slabs online, which belongs to the technical field of weighing equipment. Background technique

[0002] At present, many online slab weighing devices at home and abroad, such as Toledo SCS-20 slab scales and Yamato 25t roller scales, mostly use hydraulic jacking weighing devices. The weighing device adopts a hydraulic connecting rod lifting structure, such as figure 1 As shown, the scale body is divided into upper and lower weighing platforms. Four pressure sensors 2 and two hydraulic cylinders 3 are installed on the bottom surface of the lower weighing platform 1 . The piston rods of the two hydraulic cylinders 3 are respectively hinged with one end of the two curved arm connecting rods 4 , and the other ends of the two curved arm connecting rods 4 are hinged with the upper weighing platform 5 . When weighing, the two hydraulic cylinders 3 extend out at the same time, and push the two crank arm connect...

Embodiment 1

[0025] The online slab weighing device of this embodiment is as figure 2 , image 3 and Figure 4 As shown, including the weighing platform 8 in the pit 30 below the roller table 7, the hydraulic cylinder 3 with the piston rod 9, the pressure sensor 2, the cooling water pipe 10 and the control display device (not shown), the hydraulic cylinder 3 The signal input end and the signal output end of the pressure sensor 2 are respectively connected with corresponding ports of the control display device. A pair of gate-shaped supports 11 straddling the roller table 7 are arranged respectively on the floor on both sides of the roller table 7 . There are four pressure sensors 2, which are respectively fixed on the two ends of the crossbeam of a pair of gantry brackets 11; four pressure sensors 2 are respectively equipped with four annular connecting frames 12; there are four hydraulic cylinders 3, which are respectively fixed on four On the ring connection frame 12. One end of the...

Embodiment 2

[0032]The online slab weighing device of this embodiment is an improvement on the basis of the first embodiment, and its structure is basically the same as that of the first embodiment, as Image 6 , Figure 7 and Figure 8 As shown, the difference is: 1) the two sides of the weighing platform 8 are respectively shaped on four protruding corner frames 15; The four corner frames 15 extend horizontally into the four notches 16 respectively; 3) The door-shaped brackets 11 are two pairs of four, and do not cross the roller table 7, but are respectively placed on the floor on both sides of the roller table 7 ; 4) Four pressure sensors 2 are respectively fixed on the crossbeams of four gantry brackets 11, four annular connecting frames 12 and four hydraulic cylinders 3 on them are located above the four notches 16, and the piston rod 9 stretches out the hydraulic pressure. One end of the oil cylinder 3 vertically extends into the notch 16 and is connected with the corner frame 15,...
