Description
Technical field
The utility model relates to bearing locking technical field of tools, more particularly to a kind of convenient and practical air preheater guiding axis
Hold locking device.
Background technique
Air preheater is the relatively large equipment in boiler of power plant side, and wherein the locking of air preheater guide bearing is air preheater guide bearing
An important ring for installation, the installation quality of air preheater guide bearing directly influences the installation of air preheater next step, while also shadow
The indices run after air preheater is installed are rung, therefore, scene requires ten to air preheater guide bearing installation quality
Divide strictly, however, the locking of conventional on-site air preheater guide bearing is usually that copper rod is headed into guide bearing opening position to pass through percussion
Copper rod carries out locking bearing, leads to locking plate unbalance stress, locking plate can not normal rotation, locking force is inadequate, to guiding
Bearing apparatus injury is larger, causes air preheater guide bearing installation quality undesirable, and site operation needs during percussion
Construction personnel is wanted to fix copper rod, safety is poor when tapping operation, increases construction cost while affecting construction efficiency.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of convenient and practical air preheater guide bearing lock
Tight device.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of convenient and practical air preheater guide bearing locking device, including locking ratchet, which is characterized in that the locking
Ratchet is arranged in cirque structure, and for the locking ratchet by one piece of steel plate excision forming, the locking ratchet includes ratchet inner wall
With ratchet outer wall, the ratchet inner wall and the ratchet outer wall are arranged in concentric structure, are uniformly distributed on the ratchet inner wall
There are several ratchets, is fixed on the ratchet outer wall and be equipped with set lever, the set lever, the ratchet and the ratchet inner wall
It is arranged in integral structure, the set lever, the ratchet are concordant with the end of the ratchet inner wall to be arranged.
The internal diameter of the locking ratchet is 400mm.
The outer diameter of the locking ratchet is 480mm.
The number of the set lever is 1.
The length of the set lever is 120mm, and the width of the set lever is 60mm.
The number of the ratchet is 8.
The height and width of the ratchet are 20mm.
The length of the ratchet is 40mm.
The steel plate thickness of the locking ratchet is 30mm.
The beneficial effects of the utility model are: the utility model structure is simple, using simplicity, by the way that cirque structure is arranged
Locking ratchet, be uniformly arranged ratchet in ratchet inner wall, so that execute-in-place is convenient, bearing locking disk coupling mechanism force is uniform, passes through
Set lever is set in ratchet outer wall, ensure that guide bearing locking force meets the requirements, meets air preheater guide bearing peace
Packing quality requirement, and reduce to bearing damage degree, scene is during percussion, without additional construction personnel to locking spine
Wheel is fixed, and improves the safety for tapping operation, and then shorten the construction period, has saved construction cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- locks ratchet；11- ratchet inner wall；12- ratchet outer wall；2- set lever；3- ratchet；
It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, a kind of convenient and practical air preheater guide bearing locking device, including locking ratchet 1, feature exists
In the locking ratchet 1 is arranged in cirque structure, and the locking ratchet 1 is by one piece of steel plate excision forming, the locking ratchet
1 includes ratchet inner wall 11 and ratchet outer wall 12, and the ratchet inner wall 11 and the ratchet outer wall 12 are arranged in concentric structure, institute
It states and is evenly distributed with several ratchets 3 on ratchet inner wall 11, it is fixed on the ratchet outer wall 12 to be equipped with set lever 2, the locking
Handle 2, the ratchet 3 and the ratchet inner wall 11 are arranged in integral structure, the set lever 2, the ratchet 3 with it is described
The end of ratchet inner wall 11 is concordantly arranged.
The internal diameter of the locking ratchet 1 is 400mm.
The outer diameter of the locking ratchet 1 is 480mm.
The number of the set lever 2 is 1.
The length of the set lever 2 is 120mm, and the width of the set lever 2 is 60mm.
The number of the ratchet 3 is 8.
The height and width of the ratchet 3 are 20mm.
The length of the ratchet 3 is 40mm.
The steel plate thickness of the locking ratchet 1 is 30mm.
When the utility model is used, several ratchets 3 for locking 1 internal diameter of ratchet to gap on the outside of good guide bearing and are inserted in
On the outside of guide bearing locking plate, so that execute-in-place is convenient, bearing locking disk coupling mechanism force is uniform, then to locking 1 outer diameter of ratchet
