Abstract

The invention relates to metallurgical production, more specifically to equipment for the repair of mobile mixers. The purpose of the invention is to increase the productivity of the stand when replacing the lining. In contrast to the well-known construction of a stand similar in purpose, the mixer contains a mixer housing 3, a transport device 4 including a longitudinal drive 5. The longitudinal drive 5 interacts, on base 6, with straight line 8 and curvilinear 9 ways. The base 6 is located outside the transverse dimension of the mixer. In order to reduce metal consumption, the transport device 4 is made in the form of separate carriages 10 and 11 pivotally connected by a frame 13 and a mixer body through a mechanism. This stand construction allows the mixer body to be mounted vertically for repair. Due to this, the lining of the broken liner is self-removed through open ends into mechanized loading sites. In addition, the laying of a new lining with horizontal layers dramatically increases its quality, the degree of safety of the work being carried out, and it allows to mechanize labor. 2 Il.

increased stand productivity when replacing lining. In contrast to the well-known construction of a stand similar in purpose, the mixer contains a mixer housing 3, a transport device 4 that drives a longitudinal tilt 5. The longitudinal tilt drive 5 interacts, on base 6, with straight line 8 and curved 9 ways. The base 6 is located outside the transverse dimension of the mixer. In order to reduce metal consumption, the transport device 4 is made in the form of separate carriages 10 and I, pivotally connected by frame 13 and mixer body through a mechanism.

The invention relates to metallurgical production, more specifically to equipment for the repair of mobile mixers.

The purpose of the invention is to increase the productivity of the stand when replacing the lining.

FIG. Figure 1 shows a stand with a front-end mixer housing, side view; in fig. 2 is a view A of FIG. one.

The mobile mixer, mounted on rails 1, is stopped by the locomotive at the repair stand of the liner of case 2. This stand contains a lift 3 of case 2, a transport device 4, a drive for longitudinal inclination 5, a base 6 on which transport device A is movably placed.

The transport device 4 f is provided with support wheels 7 interacting with the rectilinear 8 and curvilinear 9 ways, made on the base 6, located outside the transverse dimension of the mixer. The transport device 4 is made in the form of separate paired-traveling carts 10 and 11, rigidly connected to each other by the body 2 of the mixer by means of screws 12, located along the edges of the traveling carriages 10 and 11 in a horizontal level, and frame 13. At the same time - All Tejzhek 10 interacts with a curvilinear path 9, and a pair of traveling trolleys 11, driven by a drive, interact with a straight line 8. The drive 5 has an incomparable braking brake and provides its traction parameters with a pin 14 along the entire linear path 8. Initial areas 15 and 16 of the straight line 8 and curvilinear paths 9, respectively, are made with a clearance but are connected to the above paths and are connected to the rods 17 of the hydraulic cylinders 18 of the lifter 3. The mixer body 2 in its extreme vertical position is partially located at point 19, in which mechanization

20 pogruzochnalk works waste lining.

The stand for lining repair of the mobile mixer case works in the following way: U1 D1M.

In the workshop for the repair of mobile mixers, a mobile mixer is transported to the special lining repair site on rails I by a locomotive. A set of auxiliary works is underway to prepare the mobile mixer for the upcoming repair of the liner of the mixer body 2 (disengaging the locomotive, ensuring that the mixer carriages remain stationary relative to the rails 1, the connections of the body 2 to the mixer carriages, etc.) are released. At this time, the transport device 4 is in its extreme upper lift by the elevator 3, in its initial horizontal position. Wheels 7 running.

10 and 11, which are interconnected by the mounting frame 13, are supported on the initial portions 15 and 16, respectively, of the rectilinear 8 and the curvilinear 9 paths. These paths are made on the basis of 6, located outside the transverse dimension of the mixer. The screws 12 are extended by the Hapyjity, and between the inner sides of the undercarriage 10 and

11 and the outer surface of the housing

For a 2xxer, there is a transport gap sufficient to allow the mixer to pass. Then when you turn on the lift

3 on the descent of the initial sections 15

and 16, connected with the rods 17 of the hydraulic cylinders 18, are lowered together with the transport device 4 arranged on them until the horizontal axes of the screws 12 coincide with the counter screw holes made in special tides on the mixer body. Due to the constant lantern engagement 14 and the normally-closed brake with the longitudinal inclination 5 off, the transport device is stationary with respect to the initial sections 15 and 16

ways. The screws 12 are then wrapped in the above holes in the mixer body 2, and the undercarriages 10, II are rigidly connected to each other by the mixer body, thereby unloading the mounting frame 13. When the lift 3 is turned on to lift, the rods 17 of the padrotsilders 18 make a working stroke, lift the body of the mixer to match the levels of the initial sections 15 and 16 with straight lines of 8 and curvilinear 9 ways, ensuring the rollout of both running trucks of the mixer in one direction. The lift 3 is turned off, the hydraulic cylinders 18 become hydrostop. When the continuous tilting drive 5 is turned on, the braking torque is removed and, under the action of the zivok gear 14, the transporting device 4, interacting with its wheels 7 with the straight line 8 and curved 9 ways, moves the mixer body 2 to the final initial vertical position. At the same time, the traveling carts 1I move along a straight line 8, and the walking carts 10 follow a curvilinear path 9. The longitudinal inclination drive 5 is turned off, the normally-closed brake is automatically activated and, due to constant clamping engagement 14, the transport device 4 with the body 2 mixer steadily and reliably takes upright position. Under the action of a known pulse-wave method of destruction, a worn-out lining block self-falls into tank 19 and removes it from there by means of the provided mechanization of loading operations. After the case of the 2nd mixer will be lined up with a new refractory material by laying it with horizontal rings, the stand for repair of fu

Terovki works in reverse order. The transport device 4, under the action of the longitudinal tilt drive 5, moves along path 8 and 9 the mixer body 2 to the extreme initial position and the mixer carts are fed. The elevator 3 lowers the body 2 to the mixer carriages, and after unscrewing the screws 12 and lifting the unloaded transporting device 4 up to its original position, the locomotive can roll out the mobile mixer on the rails 1 outside the stand.

Working at the stand is extremely convenient, due to the vertical installation of the mixer body, breaking is provided.

lining with self-removal of the rubble through the open ends of the mechanized loading sites. In addition, the laying of a new lining with horizontal rings dramatically improves its quality, the degree of safety of the work carried out allows mechanization of work.
