Description
Technical field
The utility model is related to a kind of lock collar device component, specifically a kind of interlocking machine for preventing lock collar device from malfunctioning
Structure.
Background technology
No. 201720096563.4 patents of ZL disclose a kind of lock collar Qi Fang unusual fluctuations mechanism.Lock collar Qi Fang unusual fluctuations mechanism
Including including limit cover board, the limit cover board is horizontally installed on the upper edge of the pedestal cant board of lock collar device and covers in place side
Braking fixture block top, it is described limit cover board on inside along beyond limit cover board where side braking fixture block in initial position
When sandwich serface, to limiting by the beat of brake disc between two braking fixture blocks, to prevent from rotating because of brake disc deflection
Caused by accidentally brake.The design by the way that the medial surface for limiting cover board to be extended to the upper area in the brake disc channel of lock collar device,
The friction plate on braking fixture block when thus than initial position is closer to the disk to brake disc, once beat occurs for brake disc
When rotation, limit cover board can play the role of to brake disc it is certain stabilize beat, make the wheel of brake disc along cannot be due to beat
Braking fixture block is touched, to avoid thus caused lock collar device accidentally braking, improves the job stability of lock collar device.
In practice, there is also certain deficiencies when in use for this anti-unusual fluctuation mechanism, exactly lean out portion when limit cover board
After dividing the brake disc being eccentrically rotated to rub off, anti-unusual fluctuation function also just disappears therewith, and the beat rotation of brake disc is still
Braking fixture block can be touched, to drive braking fixture block displacement, generates and accidentally brakes.
Utility model content
The purpose of this utility model is just to provide a kind of interlocking mechanism for preventing lock collar device from malfunctioning, thoroughly to eliminate lock collar
The malfunction of device improves the job stability and reliability of lock collar device.
The utility model is realized in this way：It is a kind of prevent lock collar device malfunction interlocking mechanism, including bar, connecting rod and
One end of support element, the connecting rod is hinged on the exposed elongated end of lock collar device brake pushrod, the other end and gear of the connecting rod
The rear end of bar connects, and one end support of the support element is connected on the connecting rod, and the other end of the support element is fixedly connected
On lock collar device pedestal, the bar passes through the preformed hole on lock collar device pedestal and extend into the wedge groove of lock collar device, bar
Front end be blocked under normal conditions before the braking fixture block in lock collar device, and when brake pushrod pushes braking fixture block from braking
It is getd out of the way in front of fixture block.
The utility model, can using bar as the mechanical position limitation and locking member of limitation lock collar device braking fixture block action
The shift motion of braking fixture block is effectively inhibited, meanwhile, this interlocking mechanism also connects with the brake pushrod of lock collar device, using urgent
The pushing action of brake pushrod removes the enabled instruction of limit as interlocking mechanism when braking, thus by the emergency braking of lock collar device
Limit releasing with this interlocking mechanism is dexterously linked together, and thus removes the emergency braking of lock collar device and the limit of interlocking mechanism
Except combining closely, avoid conventional mechanical position limitation prevent braking from or delay the case where occur, thus particularly suitable for
Thus the job stability and reliability of lock collar device greatly improved in the anti-locking mechanism of malfunction as deadman's brake.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the upward view of interlocking mechanism shown in Fig. 1.
In figure：1, bar, 2, connecting rod, 3, support element, 4, articulation joint bearing, 5, brake pushrod, 6, end cap, 7, braking bullet
Spring, 8, coil, 9, dynamic core, 10, lock collar device pedestal, 11, braking fixture block, 12, axis pin, 13, split pin.
Specific implementation mode
As shown in Figure 1, being provided with wedge groove in lock collar device pedestal 10, it is provided with braking fixture block 11 in wedge groove, is locking
Electromagnet is provided on disk device pedestal 10, the yoke of electromagnet is end cap 6, and electromagnet armature is dynamic core 9, moves core 9 and end cap 6
Relatively, it is worn in the core bore of the two and is connected to brake pushrod 5, tripping spring 7, coil 8 are socketed on the reducer of brake pushrod 5
It is socketed in the interior back segment for stretching section and dynamic core 9 of end cap 6.Thus lock collar device ontology is constituted.
The utility model includes the parts such as bar 1, connecting rod 2 and support element 3.The right end of connecting rod 2 is hinged on the system of lock collar device
On the exposed elongated end of dynamic push rod 5, the left end of connecting rod 2 connects with the rear end of bar 1, and one end support of support element 3 is connected to
On bar 2, the other end of support element 3 is fixedly connected on lock collar device pedestal 10, and bar 1 passes through reserved on lock collar device pedestal 10
Hole, and extending into the wedge groove of lock collar device, before the front end of bar 1 is blocked in the braking fixture block 11 in lock collar device under normal conditions
