Abstract
The utility model provides a gear pump sliding bearing dismounting tool for a large-scale extruder set, which comprises a connecting flange and a balance block which are parallel to each other, wherein one end surface of the connecting flange is connected with a sliding bearing, the other end surface of the connecting flange is connected with the balance block through a plurality of connecting plates, a first hanging ring is arranged on one side surface of each connecting plate, which is close to the connecting flange, and a second hanging ring is arranged on the balance block and is positioned in the vertical direction of the first hanging ring. Two hand hoists are connected respectively on the first rings and the second rings on the coplanar, and the balancing piece is cooperated again for the sliding bearing keeps the horizontal balance's removal at the dismouting in-process, avoids causing the sliding bearing focus to the internal dip and bump the mill rotor journal.
Description
Technical Field
The utility model relates to the technical field of disassembling tools, in particular to a disassembling tool for a sliding bearing of a gear pump of a large-scale extruder set.
Background
The gear pump of large-scale extrusion unit need tear open and examine and change rotor both sides slide bearing, and the gear pump rotor upper and lower distribution totally two, and the slide bearing is totally four about.
The existing assembly and disassembly technology tool is only a flat plate and is matched with a jackscrew for use; and this bearing is 0.15 ~ 0.20mm with gear pump shell fit clearance, and the operation about the equal being close operating temperature 200 ℃ of on-the-spot dismouting, and the bearing has a large amount of liquid polypropylene material adhesions this moment, is difficult to tear the bearing open, because of again when slide bearing pine back, frock and axle bush combination hoist and mount focus are abnormal, can't guarantee the balance, cause slide bearing focus introversion, cause to bump and grind the rotor journal.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a disassembly and assembly tool for a gear pump sliding bearing of a large-scale extrusion unit.
In order to achieve the above purpose, the utility model is realized by the following technical scheme:
large-scale gear pump slide bearing dismouting frock of extruder group, including flange and balancing piece that are parallel to each other, a flange's a terminal surface is connected with slide bearing, another terminal surface with the balancing piece is connected through a plurality of connecting plates, be close to on the connecting plate be equipped with first rings on flange's the one end side, just be located on the balancing piece be equipped with second rings on the vertical direction of first rings, first rings with second rings are connected through two hand blocks respectively.
Furthermore, the connecting plates are 3 and are equally divided between the connecting flange and the balance block.
Furthermore, a jack which is abutted against a rotor in the middle of the sliding bearing is arranged on the balance block.
Furthermore, the connecting flange is provided with 3 bolt holes and bolts matched with the bolt holes.
Furthermore, the connecting flange and the balance block are arranged in a concentric circle mode, and the outer diameter of the connecting flange is larger than that of the balance block.
The utility model has the beneficial effects that: be equipped with balancing piece, first rings and second rings, two hand hoists are connected respectively on the first rings and the second rings on the coplanar, and the balancing piece of deuterogamying for slide bearing keeps horizontal balance's removal at the dismouting in-process, avoids causing the slide bearing focus internal inclination and bump the mill rotor journal.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the present invention;
in the figure: 1. a connecting flange; 2. a counterbalance; 3. a first hanging ring; 4. a second hoisting ring; 5. a connecting plate; 6. bolt holes.
Detailed Description
The utility model is described in detail below with reference to the attached drawing figures:
as shown in fig. 1 and 2, the tool for dismounting and mounting the sliding bearing of the gear pump of the large-scale extrusion press unit comprises a connecting flange 1 and a balance block 2 which are parallel to each other, one end surface of the connecting flange 1 is connected with the sliding bearing, the other end surface of the connecting flange is connected with the balance block 2 through a plurality of connecting plates 5, a first lifting ring 3 is arranged on one end side surface, close to the connecting flange 1, of the connecting plate 5, a second lifting ring 4 is arranged on the balance block 2 and in the vertical direction of the first lifting ring 3, and the first lifting ring 3 and the second lifting ring 4 are connected through two hand hoists respectively.
3 connecting plates 5 are uniformly distributed between the connecting flange 1 and the balance block 2; so that the tool is integrally balanced and stably and balancedly connected with the connecting flange 1 and the balance block 2.
A jack which abuts against a rotor in the middle of the sliding bearing is arranged on the balance block 2; the rotor is prevented from being removed together with the sliding bearing when the sliding bearing is removed.
The connecting flange 1 is provided with 3 bolt holes 6 and bolts matched with the bolt holes; so that the connecting flange 1 is firmly connected with the sliding bearing.
The connecting flange 1 and the balance block 2 are arranged in a concentric circle mode, and the outer diameter of the connecting flange 1 is larger than that of the balance block 2; make first rings 3 be located the one end of keeping away from the slide bearing, prevent that manual hoist from bumping and grinding slide bearing when the operation.
The working principle of the utility model is as follows:
as shown in fig. 1 and 2, when the sliding bearing is disassembled, firstly, the connecting flange 1 and the sliding bearing are connected through a bolt, then a jack passes through the hollow middle part of the connecting flange and abuts against a rotor in the middle part of the sliding bearing, then two hand hoists are respectively connected to the first hoisting ring 3 and the second hoisting ring 4, and finally, the tool and the sliding bearing are horizontally moved and disassembled through the operation of the hand hoists;
when the sliding bearing is installed, the connecting flange 1 and the sliding bearing are connected through the bolts, then the two hand hoists are used for being connected to the first lifting ring 3 and the second lifting ring 4 respectively, then the installation angle is adjusted, and finally the tool and the sliding bearing are installed in a horizontal moving mode through the operation of the hand hoists.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, which are directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
