Description

Technical Field

[0001] The present application relates to the technical field of support frames, and in particular to a support frame for a lifting device for a large grinding mill. Background Art

[0002] Ball mill is the key equipment for crushing materials after they are broken. This type of grinding mill is a mill that is equipped with a certain number of steel balls as grinding media. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries to grind various ores and other grindable materials in dry or wet manner.

[0003] In industry, a platform of a certain height is often built above the ball mill to facilitate loading and maintenance. Usually, a gap is reserved on the platform, and a support frame is set on the gap for lifting powder. Since the support frame will move along the length of the gap during operation, and since the movement of the entire support frame is achieved manually, the start and stop moments of the movement and the sudden change in speed during the movement will cause the rope to shake, and in severe cases it will even touch the side wall of the support frame, affecting normal operation.

[0020] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0021] like Figure 1-4 As shown, a support frame for a lifting device for a large grinding mill includes a frame body, the bottom of which is slidably arranged at a notch 20 arranged on a top platform 2 of the grinding mill; the frame body is provided with two sets of relatively arranged limit frames 5 sliding along the height direction, and arc-shaped limit plates 53 are provided at one end of the limit frames 5 close to each other, and a restraining area for the lifting rope to pass through is formed between the two arc-shaped limit plates 53.

[0022] The support frame has a square structure, the bottom of which is slidably arranged along the length direction of the notch 20, and the top is provided with a hanging rail 3, which can specifically be an I-beam; the length direction of the hanging rail 3 is arranged perpendicular to the length direction of the notch 20, and an electric hoist 4 (crane) is slidably arranged on the hanging rail 3 for hanging the powder hopper.

[0023] The two limit frames 5 are specifically located on both sides of the width direction of the hanging rail 3. The constrained area between the arc-shaped limit plates 53 on the two limit frames 5 can play a certain restraining role on the hanging rope, thereby avoiding the shaking of the entire support frame during the movement, so as to ensure the stability of the hanging hopper.

[0024] In this embodiment, the sides of the two arc-shaped limiting plates 53 facing each other are convex to reduce the contact area with the suspension rope as much as possible.

[0025] In some further embodiments, a rotating roller 55 is rotatably provided on the arc-shaped limiting plate 53 .

[0026] Exemplarily, a rotating roller 55 is provided on the arc-shaped limiting plate 53 so that the arc-shaped limiting plate 53 can reduce the friction with the suspension rope when in contact with the suspension rope, that is, convert the previous sliding friction into the current rolling friction.

[0027] Specifically, an opening 54 is provided on the arc-shaped limiting plate 53 , a set of opposite side walls of the opening 54 are provided with a rotating shaft, and the rotating roller 55 is rotatably disposed on the opening 54 via the rotating shaft.

[0028] In some further embodiments, the limiting frame 5 includes a connecting frame 50 and a mounting rod 51, the connecting frame 50 is slidably set on the frame body, the mounting rod 51 is connected to the connecting frame 50, and the arc-shaped limiting plate 53 is slidably set on the mounting rod 51 along the opposite directions of the two limiting frames 5.

[0029] The limiting frame 5 includes a connecting frame 50 and a mounting rod 51 . There are two connecting frames 50 . The two connecting members are arranged at an interval. Both ends of the mounting rod 51 are connected to the two connecting frames 50 , respectively.

[0030] The mounting rod 51 is provided with a sliding hole, in which an adjusting screw 52 is slidably provided, an arc-shaped limit plate 53 is provided at one end of the adjusting screw 52, ​​and two adjusting nuts 520 are provided on the adjusting screw 52, ​​and the two adjusting nuts 520 are respectively located at both sides of the mounting rod 51. By adjusting the two adjusting nuts 520, the adjusting screw 52 can be moved, thereby adjusting the distance between the two arc-shaped limit plates 53.

[0031] In some further embodiments, the frame body includes four vertically arranged support rods 10 , each support rod 10 is provided with a narrow slot 100 , and the connecting frame 50 is slidably arranged in the narrow slot 100 .

[0032] Bolts are passed through the narrow slots 100 and connected to the connecting frame 50 through the narrow slots 100. When the height of the limiting frame 5 is required, the bolts can be loosened, and when the height is appropriate, the bolts can be tightened.

[0033] Since a hopper is suspended at the bottom of the lifting rope, in actual operation, the lower the limit frame 5 is set, the better the limiting effect on the lifting rope will be, but it will interfere with the rising height of the hopper to a certain extent. Therefore, the adjustment of the limit frame 5 is affected by the actual situation. During specific implementation, it is based on not interfering with the hopper.

[0034] In some further embodiments, the frame further includes a chassis 11 , on which wheels are disposed; tracks 21 are disposed on both sides of the gap 20 in the width direction, and the wheels are rollingly connected to the tracks 21 .

[0035] Tracks 21 are provided on both sides of the notch 20 along the width direction. The length direction of the track 21 is consistent with the length direction of the notch 20 . The wheels on the chassis 11 are rollingly connected to the track 21 .

[0036] The wheels can be of similar construction type to those of train wheels, but smaller in size.

[0037] In some further embodiments, a limiting roller 110 is provided on the chassis 11, and a limiting groove is provided on the platform 2. The limiting roller 110 is located in the limiting groove and rolls with the upper inner wall of the limiting groove.

[0038] There are two limit grooves, which are respectively located on both sides of the width direction of the notch 20. A limit roller 110 is provided on the corresponding side of the chassis 11. When the support frame moves along the track 21, the limit roller 110 is synchronously fixedly matched with the limit groove.

[0039] The purpose of setting the limit groove and the limit roller 110 is mainly to prevent the support frame from tipping over. Since the hopper is located on the platform 2, during lifting, the electric hoist 4 moves along the hanging rail 3, and the end of the hanging rail 3 extends above the notch 20. In order to prevent the entire support frame from becoming unbalanced and tipping over when the electric hoist 4 moves to the end of the hanging rail 3, the rotating roller 55 is rolled in the limit groove, thereby playing a certain limiting role on the entire support frame.

[0040] In some further embodiments, a limiting plate 22 is provided on the platform 2 , and a limiting groove is formed between the limiting plate 22 and the table surface of the platform 2 .

[0041] The limiting plate 22 is connected to the platform 2 by bolts.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
