Description

A vertical mill reducer with a moving device

technical field

The invention relates to a vertical mill reducer, in particular to a vertical mill reducer provided with a moving device.

Background technique

At present, the vertical mill in my country's powder industry has gradually replaced the traditional tube mill by virtue of its small footprint, low power consumption, and high output. The weight of the grinding reducer also reaches more than 100t. Since the vertical mill reducer is installed directly below the grinding body of the vertical mill, the space is narrow and the hoisting is difficult, so it is inconvenient to move in and out of the large vertical mill reducer.

The existing vertical mill reducers lack a structural design that facilitates their movement. Because most of these reducers are used outdoors, it is inconvenient to lift them. In the past, a lot of manpower and auxiliary equipment such as rolling rods and hoists were needed to pull the reducer from the grinding body. Out, the efficiency is very low, which brings inconvenience to the installation and maintenance of the reducer.

Contents of the invention

The invention provides a vertical mill reducer provided with a moving device, which solves the problem of inconvenient installation and maintenance caused by difficulty in movement of the existing vertical mill reducer.

The present invention is realized through the following technical solutions:

A vertical mill reducer provided with a moving device, comprising a vertical mill reducer, two groups of mutually perpendicular rectangular grooves are arranged on the bottom plate of the vertical mill reducer, a rectangular through hole is arranged at the bottom of the rectangular groove, and a rectangular through hole is arranged on the rectangular groove Rolling rod, and the diameter of the rolling rod is smaller than the width of the rectangular slot, the diameter of the rolling rod is larger than the width of the rectangular through hole, the rectangular slot is provided with a pressing plate, the pressing plate is connected to the bottom plate by screws, when the screw locks the pressing plate on the bottom plate , the lowest point of the rolling rod is lower than the bottom surface of the bottom plate.

The further improvement of the present invention is that the sectional view of the pressing plate is T-shaped, and the two ends of the T-shaped transverse part are provided with threaded holes, and the screws pass through the threaded holes to connect the pressing plate and the bottom plate; the vertical part of the T-shaped is inserted into the In the rectangular groove, and the bottom surface of the vertical part of the T shape is pressed on the rolling rod.

A further improvement of the present invention is that a jack is provided above the pressing plate, and when the jack pushes the pressing plate to be pressed against the bottom plate, the lowest point of the rolling bar is lower than the bottom surface of the bottom plate. That is, use the jack to push the pressure plate first, and the pressure plate pushes the roller to lift the vertical mill reducer.

A further improvement of the present invention is that the two groups of mutually perpendicular rectangular grooves are respectively arranged on the left and right sides and the front and rear sides of the bottom plate. According to the moving direction, lock the pressure plate above one of the sets of rectangular grooves, so that the roller rod will lift up the vertical mill reducer, so that the vertical mill reducer can move in one direction, that is, one set is used for the front and rear of the vertical mill reducer. The other group is used for the left and right movement of the grinding reducer.

Compared with the prior art, the present invention has the following advantages:

The invention is simple in structure and easy to operate. The vertical mill reducer adds a moving device on the original basis, which reduces the number and time of auxiliary tools required for the vertical mill reducer to move in and out of the grinding body, and can effectively improve the speed reduction of the vertical mill. Machine installation and maintenance efficiency.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Fig. 1, Fig. 2 and Fig. 3, a vertical mill reducer provided with a moving device includes a vertical mill reducer 1, and the bottom plate 3 of the vertical mill reducer 1 is provided with two sets of mutually perpendicular rectangular Groove 4, the bottom of rectangular groove 4 is provided with rectangular through hole 6, and rectangular groove 4 is provided with rolling bar 5, and the diameter of rolling bar 5 is less than the width of rectangular groove 4, and the diameter of rolling bar 5 is greater than the width of rectangular through hole 6, rectangular Groove 4 is provided with pressing plate 7, and this pressing plate 7 is connected on the base plate 3 by screw 8, when screw 8 locks pressing plate 7 on base plate 3, the lowest point of rolling bar 5 is lower than the bottom surface of base plate 3, and described pressing plate The cross-sectional view of 7 is T-shaped, and the two ends of the T-shaped horizontal part are provided with threaded holes, and the screws 8 pass through the threaded holes to connect the pressure plate 7 with the bottom plate 3; the vertical part of the T-shaped is inserted in the rectangular groove 4, and The bottom surface of the T-shaped vertical part is pressed on the roller bar 5, and a jack 2 is arranged above the press plate 7, and when the jack 2 pushes the press plate 7 to be pressed tightly on the bottom plate 3, the lowest point of the roller bar 5 is lower than the bottom surface of the bottom plate 3, The two groups of rectangular slots 4 perpendicular to each other are respectively arranged on the left and right sides and the front and rear sides of the bottom plate 3 .

It should be noted that those skilled in the art can make some improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
