Abstract
The utility model relates to a jacking tool for small-gap shafts, which comprises a semi-circular support ring and two L-shaped jacking plates, wherein both ends of the top of the semi-circular support ring are vertically and upwards integrally extended to form a small extending section, the top of the extending section is provided with a fixing lug, each L-shaped jacking plate is respectively positioned below the corresponding fixing lug, one end of the short side of each L-shaped jacking plate is arranged on the extending section through a bolt, and the top of the long side of each L-shaped jacking plate is tightly attached to the bottom of the fixing lug; the length of the long edge of the L-shaped jacking plate is greater than that of the fixing lug. The utility model can replace the bearing or the bearing seat by the jacking shaft only by inserting the semi-circular support ring into the gap between the bearing seat and the shell, connecting the two L-shaped jacking plates by using bolts and arranging a jack below the two L-shaped jacking plates respectively, thereby solving the problem that the bearing seat and the shell have small clearance and cannot be jacked; overall structure is simple, and is easy and simple to handle, and is with low costs, safe and reliable can promote work efficiency, has very strong practicality.
Description
Technical Field
The utility model belongs to the technical field of machining, especially, relate to a be used for close clearance axle jacking instrument.
Background
At present, a plurality of elevators and belt conveyors need to replace bearings, but because the clearance between the bearing seat and the shell is small, the bottom space is small, the jack cannot be used, and the function is difficult to play. In the existing structure, a gap of 5-10cm is generally reserved between a bearing seat and a shell, the distance from a shaft to the bottom is only about 10-15cm, and a jack cannot be placed in the existing structure. If tools such as a steel wire rope and a hand chain are used, a top supporting beam is needed, but the top has no suspension amount due to the fact that part of mechanical equipment is high.
Disclosure of Invention
The utility model discloses a solve the problem that exists among the prior art, a be used for little clearance axle jacking instrument is proposed, the little jacking problem that can not in clearance between bearing frame and the casing can be solved to this instrument, adopt two half arc support ring to connect, the bearing capacity of instrument has been improved, and simultaneously, both sides have designed the jacking board that can dismantle, conveniently insert among this kind of little gap with this instrument, after inserting the gap, utilize bolted connection jacking board, make it form a little instrument that can the jacking, both sides jacking board below sets up the jack respectively, just can reach and utilize the jacking axle to change bearing or bearing frame.
The utility model discloses a realize like this, a be used for little clearance axle jacking instrument, including half-circular arc support ring and two L type jacking boards, the equal vertical integrative extension that makes progress in top both ends of half-circular arc support ring has a little extension, the top of extension has fixed ear, every L type jacking board is located corresponding fixed ear below respectively, and L type jacking board minor face one end passes through the bolt and installs on extending the section, the top on the long limit of L type jacking board is hugged closely with the bottom of fixed ear.
In the above technical solution, preferably, the length of the long side of the L-shaped lifting plate is greater than the length of the fixing lug.
In the above technical solution, preferably, the semi-circular support ring is a double semi-circular support ring with a hollow middle.
The utility model has the advantages and positive effects that:
by adopting the above technical scheme, the utility model, can realize when bearing or bearing frame need be changed, only need insert the gap between bearing frame and the casing with the half-circular arc support ring, then utilize two L type jacking boards of bolted connection, set up a jack respectively in two L type jacking board belows again, just can reach and utilize the jacking axle to change bearing or bearing frame. The utility model has the advantages of simple overall structure, reasonable in design is compact, and is easy and simple to handle, and is with low costs, and safe and reliable can promote work efficiency, has very strong practicality, has solved the little problem that can not the jacking in clearance between bearing frame and the casing.

In the figure: 1. a semi-circular arc support ring; 2. an L-shaped jacking plate; 3. an extension section; 4. fixing the ear; 5. and (4) bolts.
Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:
please refer to fig. 1 and 2, an embodiment of the present invention provides a jacking tool for small gap shafts, including a semi-circular support ring 1 and two L-shaped jacking plates 2, a small extension section 3 is vertically extended upwards at both ends of the top of the semi-circular support ring 1, the top of the extension section 3 has a fixing lug 4, every the L-shaped jacking plate 2 is located below the corresponding fixing lug 4 respectively, and one end of the short side of the L-shaped jacking plate 2 is installed on the extension section 3 through a bolt 5, the top of the long side of the L-shaped jacking plate 2 is tightly attached to the bottom of the fixing lug 4.
Preferably, the length of the long edge of the L-shaped jacking plate 2 is greater than that of the fixed lug 4, so that jacking is facilitated.
Preferably, the semi-circular support ring 1 is a double semi-circular support ring with a hollow middle, so that the bearing capacity of the tool is improved.
The utility model discloses can realize when bearing or bearing frame need be changed, only need insert the gap between bearing frame and the casing with half-circular arc support ring 1, then utilize bolt 5 to connect two L type jacking boards 2, set up a jack respectively in two L type jacking boards 2 below, just can reach and utilize the jacking axle to change bearing or bearing frame. The utility model has the advantages of simple overall structure, reasonable in design is compact, and is easy and simple to handle, and is with low costs, and safe and reliable can promote work efficiency, has very strong practicality.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
