Abstract
The present invention relates to a kind of lockable mechanisms of canvas top-fastener propping roller, it is characterised in that：Including supporting rod, pawl, ratchet and bearing, the supporting rod is mounted on propping roller when in use, and the pawl is mounted on support boom end and can rotate freely；The bearing is arranged below supporting rod, and bearing is mounted in the rack of canvas top-fastener when in use, and the ratchet is fixedly mounted on bearing, and ratchet position is corresponding with the detent positions.It is the configuration of the present invention is simple, compact, propping roller effectively can be solved the problems, such as because of Gravitational sliding, and will not increase excessive cost, safeguard also very convenient in the case where not changing existing equipment structure.
Description
Technical field
The present invention relates to a kind of lockable mechanisms, the specifically lockable mechanism of canvas top-fastener propping roller.
Background technology
When planning paper machine canvas top-fastener, inevitably needed sometimes by this device slant setting.At this moment must consider
To when changing canvas, due to losing canvas tension, the propping roller for being located at inclined surface can be brought not because of Gravitational sliding to canvas operation is changed
Just the problems such as.The mode for solving the problems, such as this in the past is to use the bearing housing with self-locking function, but its cost is higher, maintenance maintenance
Also inconvenient.
Invention content
It is an object of the present invention to overcome the shortcomings of the prior art and provide a kind of locks of canvas top-fastener propping roller
Locking mechanism, it is simple in structure, compact, propping roller can be effectively solved because under gravity in the case where not changing existing equipment structure
Sliding problem, and excessive cost will not be increased, it safeguards also very convenient.
According to technical solution provided by the invention：The lockable mechanism of canvas top-fastener propping roller, it is characterised in that：Including branch
Strut, pawl, ratchet and bearing, the supporting rod are mounted on propping roller when in use, and the pawl is mounted on support rod end
Portion can simultaneously rotate freely；The bearing is arranged below supporting rod, and bearing is mounted in the rack of canvas top-fastener when in use,
The ratchet is fixedly mounted on bearing, and ratchet position is corresponding with the detent positions.
As a further improvement on the present invention, it is connected with handwheel on the ratchet.
Compared with prior art, the present invention having the following advantages that：It is the configuration of the present invention is simple, compact, can not change it is existing
In the case of device structure, propping roller effectively is solved the problems, such as because of Gravitational sliding, and will not increase excessive cost, safeguard also very
It is convenient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific implementation mode
With reference to specific drawings and examples, the invention will be further described.
As shown in the figure：The lockable mechanism of canvas top-fastener propping roller in embodiment is mainly by supporting rod 1, pawl 2, ratchet
4 and bearing 3 form, the supporting rod 1 is mounted on propping roller when in use, and the pawl 2 is mounted on 1 end of supporting rod and can
It rotates freely；The bearing 3 is arranged below supporting rod 1, and bearing 3 is mounted in the rack of canvas top-fastener when in use, institute
It states ratchet 4 to be fixedly mounted on bearing 3,4 position of ratchet is corresponding with 2 position of the pawl.
When concrete application, since pawl 2 can rotate freely, under the effect of gravity, pawl 2 is to be in overhang always；
When replacing canvas, due to losing canvas tension, the propping roller for being located at inclined surface can be because of Gravitational sliding, when propping roller glides, spine
Pawl 2 also moves down, and after propping roller downslide certain distance, 2 end of pawl can snap onto on the ratchet 4 of lower section, pawl 2 and spine
Wheel 4 cooperation realize lockings, avoid propping roller glide to change canvas operation make troubles.
As shown in Figure 1, in the present embodiment, it is connected with handwheel 5 on the ratchet 4, can facilitate dimension with mechanism in this way
Repair maintenance.
