Description

Auxiliary device for roller dismounting

Technical Field

The utility model relates to an auxiliary device, especially an auxiliary device is used in roller dismouting.

Background

The surface cleaning machine set and the coating machine for the metal strip have a large number of various rollers, the rollers run at high speed in acid, alkali and high-temperature environments for a long time, and the maintenance, the maintenance and the replacement frequency of the rollers are very high.

Due to the very high precision requirements of the roller surface, the rollers can be out of service due to slight collision during installation and are limited by the structure, so that the assembly and disassembly of the rollers are very difficult.

Disclosure of Invention

The utility model aims to solve the technical problem that an auxiliary device is used in roller dismouting is provided, can improve roller change efficiency, reduces roller surface damage rate simultaneously.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

the auxiliary device for disassembling and assembling the rollers comprises paired hanging rails, wherein the hanging rails are installed on a shell or a support supported by the rollers and are parallel to the axis of the roller assembly, and a lifting appliance is connected with the necks of non-working shafts of the front and rear rollers in a clamping mode and is arranged on the hanging rails in a sliding mode through a walking wheel assembly on the left and right sides.

The lower end of the walking wheel assembly is installed on the lifting appliance through an adjusting bolt.

The lifting appliance comprises a lifting plate, a clamping groove matched with the roller assembly is arranged in the middle of the lifting plate, and through holes for the adjusting bolts to pass through are formed in the two ends of the lifting plate.

The utility model relates to an auxiliary device is used in roller dismouting has following technological effect:

1) the original roller assembly is assembled on a unit after a roller is hung, and 3-4 maintenance personnel are needed for working for 2 hours for a single roller. All parts of the roller assembly are integrally hoisted after being assembled into a complete part on a workbench of a workshop, and only 2 maintenance personnel need to work for half an hour. Thereby greatly improving the working efficiency.

2) After the roller assembly is assembled on the workshop workbench, the assembly precision is greatly improved, and a plurality of sets of complete roller assemblies can be assembled on the workshop workbench by spare parts for standby use. In addition, the precision after the roller assembly is assembled can be detected outside the unit, if the defect can be solved outside the unit, the problem can not be found after the roller assembly is installed on the unit, and the roller assembly needs to be disassembled and assembled again.

3) When dismantling the double roll subassembly in the past, need demolish the lower roll subassembly earlier when dismantling the upper roll subassembly, need demolish the upper roll subassembly earlier when dismantling the lower roll subassembly, adopt this device after, only need with one of them roller assembly rise or fall can, no longer need demolish corresponding roller set.

4) The roller assembly integrally translates into and out of the unit, the surface of the roller does not need special protection, and a specially-assigned person is not needed to observe during installation.

In the figure: the lifting device comprises a lifting rail 1, a shell 2, a lifting appliance 3, a walking wheel assembly 4, a roller assembly 5, an adjusting bolt 6, a lifting plate 3-1, a clamping groove 3-2 and a through hole 3-3.

Detailed Description

As shown in fig. 1, an auxiliary device for attaching and detaching a roller includes a pair of hanger rails 1, and the hanger rails 1 are attached to a housing 2 or a holder supported by the roller. A single hanger rail 1 can bear more than 450 kilograms, so that the hanger rail 1 has enough strength and rigidity, and the roller assembly 5 is prevented from being damaged due to deformation during hoisting.

The paired walking wheel assemblies 4 are arranged on the left and right suspension rails 1, and the walking wheel assemblies 4 are installed in slideways in the suspension rails 1 and can be penetrated from two ends after the suspension rails 1 are installed. The lower end of the walking wheel component 4 is fixed with an adjusting bolt 6, and the other end of the adjusting bolt 6 is arranged on the lifting appliance 3. The lifting appliance 3 comprises a lifting plate 3-1, a clamping groove 3-2 matched with the roller assembly 5 is arranged in the middle of the lifting plate 3-1, and the lifting appliance 3 is clamped with the neck parts of the non-working shafts of the front roller and the rear roller through the clamping groove 3-2.

Through holes 3-3 for the adjusting bolts 6 to pass through are arranged at the two ends of the hanging plate 3-1. The adjusting bolt 6 passes through the through hole 3-3 and then is locked by a nut. The height of the hanger plate 3-1 is adjusted by turning the nut, facilitating the raising or lowering of the roller assembly 5.

The roller assembly 5 comprises a roller, a coupling, a bearing seat and the like, and the roller assembly is installed in a whole hoisting machine set after being installed on a workshop workbench.

The working principle and the process are as follows:

1) and as shown in fig. 4, removing the inner sealing plate and the outer sealing plate of the corresponding roller assembly 5 on the unit.

2) The corresponding set of rollers in the two-roller subassembly (as shown in fig. 7-9) is raised or lowered out of contact with the rollers to be removed.

3) Installing a left hanging rail 1 and a right hanging rail 1, and penetrating a traveling wheel assembly 4 from the end parts of the hanging rails 1;

5) removing bearing block bolts, couplings and the like in the roller assembly 5; clamping the lifting appliance 3 into the neck part of the non-working shaft, penetrating the adjusting bolt 6 through the lifting appliance 3, tightening the nut on the adjusting bolt 6 and lifting the roller assembly 5;

7) and the roller assembly 5 is pulled out along the rail.

8) The roller assembly 5 is moved to a shop service station with a crane or other device.
