Embodiment 1

[0032] Such as Figure 1~4 As shown, Embodiment 1 of the present invention provides an integrated device for quantitative control and follow-up inspection of bolt installation torque, including a center sleeve 21, an outer circular sleeve 22, and a bearing 24 arranged on the outer periphery of the center sleeve 21, a center ring 25, a pressure Ring 27, positioning disc 29 and dial 210; the center sleeve 21 and the outer ring sleeve 22 are respectively used to connect the input shaft 1 and the output shaft 3; the center sleeve 21 is a hollow shaft with multiple steps on the outside; The center ring 25 is arranged on the outer periphery of the center sleeve 21 and is connected to the center sleeve 21 through a bearing 24; the outer circular sleeve 22 is fixedly connected to one side of the center ring 25 through a fixing bolt 211; the pressure ring 27 is located on the center ring 25, the other side is connected with the center sleeve 21 through a key and rotates synchronously w...

Embodiment 2

[0045] Such as Image 6 As shown, it is a structural schematic diagram of a bolt installation torque quantitative control and follow-up inspection integrated device provided in Embodiment 2 of the present invention. In this embodiment, the center sleeve 21, the outer circular sleeve 22, the bearing 24, the center ring 25, The pressure ring 27, the positioning disc 29 and the dial 210 are all the same as the first embodiment; the difference from the first embodiment is that in this embodiment, the rolling body 26 is a roller, and the roller is a cylindrical column, which is close to the axis of the pressure ring 27 The diameter of one side is small, and the rolling element groove 251 on the center ring 25 is a semi-cylindrical groove. In addition, the cross section of the shallow groove 271 and the deep groove 272 on the pressure ring 27 is cylindrical. In addition, in this embodiment, the spring set 28 is a helical spring set. Such as Figure 7 Shown is a schematic diagram o...

Embodiment 3

[0048] Embodiment 3 of the present invention provides an integrated device for quantitative control and follow-up inspection of bolt installation torque. In this embodiment, the structure of the device is basically the same as in Embodiment 1. The difference from Embodiment 1 is that the integrated device for quantitative control and follow-up inspection of bolt installation torque in this embodiment also includes a data monitoring system 4, specifically ,Such as Figure 8 As shown, the data monitoring system 4 includes a pressure sensor 41 , a data recording and transmission module 42 , a host computer 43 , a logic judgment module 44 , and an on-site indication and alarm module 45 .

Abstract

The invention relates to the field of mounting of anchor rods of mines, and discloses a quantitative control and follow-up test integrated device for mounting torque of the anchor rods. The device comprises a central sleeve, an outer circle sleeve as well as a bearing, a central ring, a pressing ring, a positioning disk and a dial which are arranged on the periphery of the central sleeve; the central sleeve and the outer circle sleeve are connected with an input shaft and an output shaft respectively; the central ring is arranged on the periphery of the central sleeve and is connected with thecentral sleeve through the bearing; the outer circle sleeve is fixedly connected with one side of the central ring through a bolt; the pressing ring is located on the other side of the central ring;rolling bodies are arranged between the pressing ring and the central ring; a rolling body groove is formed in the position, corresponding to the rolling bodies, of the central ring; an annular shallow groove is formed in the position, corresponding to the rolling bodies, of the pressing ring; multiple deep grooves matched with the rolling bodies in shape are evenly distributed in the shallow groove; a spring group is arranged between the pressing ring and the positioning disk; and the dial is arranged on the outer side of the positioning disk and is fixedly connected with the positioning disk. By the aid of the device, quantitative control on the mounting torque of the anchor rods of roadways can be realized.

Description

technical field [0001] The invention relates to the field of mine bolt installation, in particular to an integrated device for quantitative control and follow-up inspection of bolt installation torque. Background technique [0002] Bolt as active support is one of the most effective support forms for mine roadway support at present. Every year, the amount of bolts used in my country's coal mine roadways reaches more than 1 billion, and thousands of kilometers of new roadways are excavated. The most important indicator of bolt active support is prestress, but this indicator is difficult to observe intuitively, and the construction quality can only be determined through post-mortem inspection. Therefore, for bolt support, it is very important to quantitatively control the prestress of the bolt and realize the installation to be qualified, which is very important to improve the effect of roadway bolt support and the quality of roadway support. [0003] The existing bolt prest...
