shown in the figure:

1. the device comprises a chain block 2, an electronic hook scale 3, a pressure roller 4, a mounting seat 5, a material 6, a sintering machine trolley 7, a suspension beam 8 and a shackle.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in fig. 1, the utility model discloses a be located sintering machine platform truck 6 top and along the nip rolls 3 of the setting of 6 width direction of sintering machine platform truck, install respectively in a mount pad 4 at the both ends of nip rolls 3, every mount pad 4 respectively through an electron lifting hook balance 2 with a chain hoist 1 lower extreme is connected, every chain hoist 1 upper end all is connected on suspension beam 7. The two electronic hook scales 2 are equidistant from the gravity center of the nip roll 3.

The mounting seat 4 is a bearing seat, and two ends of the nip roll 3 are rotatably connected with the bearing seat. Each mounting seat 4 is provided with a shackle 8. The upper end of the electronic hook scale 2 is a hanging ring, the lower end of the electronic hook scale 2 is a hanging hook, the hanging hook of the electronic hook scale 2 is connected with a hook ring 8 on the mounting base 4, the hanging ring of the electronic hook scale 2 is hung on a hook at the lower end of the inverted chain 1, a hook at the upper end of the inverted chain 1 is hung on a hanging beam 7, and the hanging beam 7 is fixed with a machine head of a sintering machine trolley 6. In this embodiment, the hook of the electronic hook scale 2 is connected to the shackle 8 on the mounting base 4 by a connecting chain 9.
