This auxiliary tool does not require a lot of manpower and improves the tile grinding efficiency.

Description

An auxiliary tool for grinding large-scale bearing pads of rod mills

technical field

The utility model relates to a finishing technology for a bearing pad of a rod mill, in particular to an auxiliary tool for grinding a large bearing pad of a rod mill.

Background technique

Usually, the wet overflow type rod mill needs to be transported to the installation site for on-site installation during installation. When installing the bearing pad, since the bearing pad is a rough pad, it needs to be ground before installation. Due to the huge weight of the bearing pad, it is difficult to Grinding rough tiles requires a lot of manpower, resulting in a huge scraping workload and low scraping efficiency.

Utility model content

The technical problem to be solved by the utility model is to provide a large-scale bearing pad grinding auxiliary tool for a rod mill that improves the scraping and grinding efficiency of the bearing pad.

In order to achieve the above purpose, the utility model provides the following technical solutions: a large-scale bearing pad grinding auxiliary tool for rod mills, including a right-angled triangle bracket composed of channel steel, angle steel, and seamless steel pipe connected end to end in sequence, and the right-angled triangle The bracket is fixedly installed on the top of the cylinder edge of the coal mill, the shorter right-angled side of the right-angled triangle bracket is perpendicular to the horizontal plane, the other longer right-angled side is parallel to the axis of the cylinder, and the longer side of the right-angled triangle bracket The right-angled side is located above the shaft connected to the end of the barrel, and two inverted chains are suspended from the end of the longer right-angled side of the right-angled triangle support.

Preferably, the two inverted chains are suspended on the bracket through hooks arranged at the ends of the longer right-angled sides of the right-angled triangle bracket.

Preferably, the material of the right-angled triangle support is Q235B steel, and the load of the inverted chain is at least 3 tons.

With the above technical scheme, when in use, the free ends of the two chains are directly buckled to the two ends of the bearing bush, and the bearing bush is hung above the shaft connected to the end of the cylinder, and the inner circular surface of the bearing bush is in contact with the shaft. When lapping tiles, a worker at both ends of the bushing needs to pull the chain up so that the inner circle of the bushing slides along the surface of the shaft, thereby realizing lapping. Using the utility model to grind tiles does not require a lot of manpower, and improves the efficiency of tile grinding.

Detailed ways

Below in conjunction with accompanying drawing, by describing embodiment, the utility model is further described:

As shown in Figures 1 and 2, the utility model is a large-scale bearing pad grinding auxiliary tool for a rod mill. It is fixedly installed on the top edge of the barrel 2 of the coal mill. The cross section of the barrel 2 is circular. The shorter right-angled side of the right-angled triangle bracket 1 is perpendicular to the horizontal plane, and the other longer right-angled side is parallel to the axis of the barrel 2. , and the longer right-angled side of the right-angled triangle bracket 1 is located above the shaft 6 connected to the end of the cylinder body 2, two inverted chains 3 are suspended from the end of the longer right-angled side of the right-angled triangle bracket 1, and the two inverted chains 3 are set by setting The hook 4 at the end of the longer right-angled side of the right-angled triangle support 1 is suspended on the right-angled triangle support 1, which is convenient for the operator to pull the reverse chain 3.

When in use, directly buckle the free ends of the two inverted chains 3 to the two ends of the bearing bush 5, hang the bearing bush 5 above the shaft 6 connected to the end of the cylinder body 2, and make the inner circular surface of the bearing bush 5 contact the shaft , When grinding tiles, a staff member is required at both ends of the bearing bush 5 to pull the reverse chain 3, so that the inner circular surface of the bearing bush 5 slides along the surface of the shaft, thereby realizing grinding tiles. Using the utility model to grind tiles does not require a lot of manpower, and improves the efficiency of tile grinding.

The negative weight of the inverted chain 3 described in the utility model should be greater than or equal to 3 tons, and the material of the right-angled triangle support 1 is Q235B steel.

The above is only the preferred embodiment of the utility model, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the utility model, some deformations and improvements can also be made. Belong to the protection scope of the utility model.
