Abstract

The utility model discloses a rolling mill roll collar rapid detection device, which comprises a bracket and two carrier rollers, wherein the bracket is placed on a detection platform; the two carrier rollers are horizontally arranged and have the same height, the axes of the two carrier rollers are parallel to the axis of a roll collar of the rolling mill to be detected, and each carrier roller is rotationally connected with the bracket; the rolling mill roll collar to be detected is placed on the two carrier rollers. The utility model discloses utilize two bearing rollers to bear the weight of the rolling mill collars that wait to detect, make the collars can easily rotate, just so reduced measurement personnel's intensity of labour, improved the detection efficiency of collars. Because the roll collar can not move in the rotating process, the occupied space required by detection is small. Furthermore, the utility model discloses simple structure still has, convenient operation, advantages such as reliability height.

Description

Quick detection device of rolling mill collars

Technical Field

The utility model relates to a use when detecting rolling mill collars, can make device of collars free rotation belongs to and detects technical field.

Background

The roll collar of a rolling mill needs to be carefully detected for a roll groove after the roll collar is broken down or repaired, and the roll collar needs to be rotated in the detection process in order to detect each part of the roll collar. Because the roll collar is heavy, the roll collar rolls on the platform when being detected in the past, and the detection method not only needs to occupy larger space, but also wastes time and labor, and can seriously affect the detection efficiency, so that improvement is needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a quick detection device of rolling mill collars to the drawback of prior art to reduce measurement personnel's intensity of labour, improve collar detection efficiency.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a rapid detection device for a rolling mill roll collar comprises a support and two carrier rollers, wherein the support is placed on a detection platform; the two carrier rollers are horizontally arranged and have the same height, the axes of the two carrier rollers are parallel to the axis of a roll collar of the rolling mill to be detected, and each carrier roller is rotationally connected with the bracket; the rolling mill roll collar to be detected is placed on the two carrier rollers.

According to the device for rapidly detecting the roll collar of the rolling mill, the support is of a U-shaped structure, each carrier roller is connected with the support through a pin shaft, the carrier roller is sleeved in the middle of the pin shaft, two ends of each carrier roller are connected with the pin shaft through bearings, two ends of each pin shaft are located in through holes in vertical plates at two ends of the support respectively, one end of each pin shaft is provided with a limiting disc in the shape of a bolt head, and the other end of each pin shaft is provided with a locking nut.

According to the quick detection device for the roll collar of the rolling mill, the distance between the axes of the two carrier rollers is equal to the distance between the axis of each carrier roller and the axis of the roll collar of the rolling mill to be detected.

The utility model discloses utilize two bearing rollers to bear the weight of the rolling mill collars that wait to detect, make the collars can easily rotate, just so reduced measurement personnel's intensity of labour, improved the detection efficiency of collars. Because the roll collar can not move in the rotating process, the occupied space required by detection is small. Furthermore, the utility model discloses simple structure still has, convenient operation, advantages such as reliability height.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of the mounting of the idler on the cradle.

The reference numbers in the figures are as follows: 1. the device comprises a support, 2, a roller ring, 3, a carrier roller, 4, a pin shaft, 5, a locking nut, 6 and a bearing.

Detailed Description

The utility model provides a quick detection device of rolling mill collars, the device can realize reducing measurement personnel's intensity of labour to the short-term test of collars to reduce the space that the detection needs occupy.

Referring to fig. 1, the utility model mainly comprises a bracket 1, a supporting roller 3, a pin shaft 4, a locking nut 5 and a bearing 6. The assembly process of the device is as follows:

the first step is as follows: an iron plate with the thickness of 3.5mm is used for scribing, cutting and punching, and the iron plate is welded into the U-shaped bracket 1.

The second step is that: and assembling the pin shaft 4, the 30304 thrust bearing 6, the carrier roller 3 and the lock nut 5 on the bracket 1. As shown in fig. 2.

The utility model discloses a use method:

when the roll collar of the rolling mill which is failed or repaired needs to be detected, the roll collar to be detected is placed on the two carrier rollers 3, the rolling groove at the upper part of the roll collar is carefully detected, after the rolling groove at the upper part is detected, the roll collar is slightly rotated by hands, the rolling groove at the lower part is rotated to the upper part, and then the detection is carried out until all the rolling grooves are detected.

Before the device is not used, the roller ring needs to roll back and forth, and the roller ring is heavy, so that the time and labor are wasted, the inspection efficiency is low, and the time is about 10 minutes. After the device is put into use, when the roll collar is inspected, the device is labor-saving and convenient to rotate, the inspection can be completed in 3 minutes, and the detection efficiency is improved by more than 2 times. The device is matched with an electronic magnifier for use, and the roll collar groove is extremely convenient and fast to check. The device is strong in universality and can be used for detecting the roll rings of different models.

Utility model puts into operation the back, has perfected on-spot measurement management system, has compensatied the vacancy that does not have detection device always. Meanwhile, the improvement of the roll collar groove rolling quality is promoted, the hidden trouble caused by roll collar processing is eliminated, and the fault rate of the roll collar is reduced. The device not only brings economic benefits to enterprises, but also ensures the surface quality of fine steel, has practical application value, and is worthy of popularization.
