Embodiment
As shown in figure 1, two braking fixture blocks 7 it is parallel be arranged on base 2 formed between two cant boards 22
In wedge-shaped slot, two braking fixture blocks 7 are oppositely arranged, and the back side of braking fixture block 7 is horizontal slope, forms brake clip block body
It is parallel brake disc passage between sphenoid, but two braking fixture blocks.Friction plate is provided with the sandwich serface of braking fixture block 7
4, it is provided with horizontal concrete chute 71 at the back side of braking fixture block 7.
The aperture of the inserting hole on inserting hole, two braking fixture blocks 7 is had on two sandwich serfaces for braking fixture block 7
Relatively, pole 6 is worn in the inserting hole being connected on two braking fixture blocks 7.The diameter of pole 6 is less than the diameter of inserting hole, makes pole 6
Can be axially movable.The central axis of inserting hole is made in the sandwich serface of braking fixture block 7, the deep-controlled of inserting hole when two
When dynamic fixture block is in clamping retarder location, pole still has axial activity surplus, makes brake clip to avoid pole from withstanding braking fixture block
The situation that block can not clamp brake disc occurs.Inserting hole is opened in the sandwich serface of braking fixture block 7 on the position of front lower portion, with
Just this synchronizing control is enable to get out of the way the brake disc passage between two braking fixture blocks, it is ensured that hoist engine class crane gear
Normal work.
The utility model can pass through mutual grafting in an action for braking the controlled implementation brake hard of fixture block 7
Pole 6, drives another to brake fixture block synchronization action, and the compound sphenoid for constituting two braking fixture blocks agrees with the wedge in base
In shape groove, so as to extremely be acted to the folder that brake disc implements fast and stable, so as to improve the reliability of lock collar device.
The utility model is socketed a top spring 5 also on pole 6, and the two ends of top spring 5 act against the sandwich serface of braking fixture block 7
On, by the leading section for braking fixture block 7 to both sides ejection, support mechanism before playing a part of.
In Fig. 1, the rear support mechanism of lock collar device is a U-shaped spring fork 9, and two up extension ends of U-shaped spring fork 9 are bent into forward
The plug of knuckle, is provided with jack on the rear end face of braking fixture block 7, and a plug is plugged on the jack on a braking fixture block 7
In, the elastic reset extension for pitching 9 using U-shaped spring is acted on, and the rear end of braking fixture block 7 can be made to abut on cant board 22.
Under the cooperation of preceding support mechanism and rear support mechanism, it can be achieved to lean on wall support to the elasticity for braking fixture block, so
Achieve that braking fixture block stabilization and brake disc passage it is unobstructed, be also beneficial to avoid the generation of brake condition by mistake.
The base 2 of lock collar device includes the heavy wall cant board 22 that is oppositely arranged of bottom plate 21 and two, bottom plate 21 and two it is edge-on
Plate 22 is the integrally manufactured shaping of mild steel with high intensity, can keep maximum rigidity.The inwall of two cant boards 22 is
Horizontal slope, makes to form the wedge-shaped slot that front opening is big, open rearward end is small between two cant boards 22.Opened on cant board 22
Have and wear the mounting hole for connecing brake activating mechanism.The mounting hole is ladder circular hole, and brake activating mechanism 10 is arranged in the mounting hole.
Brake activating mechanism 10 is connected by compression spring with brake pushrod 12.Brake activating mechanism 10 can be electromagnetism
Iron, hydraulic means or pneumatic means etc. can be dead electricity triggerings or obtain the working method of electric triggering.Braking triggering
Mechanism 10 is from the outside of cant board 22 insertion mounting hole, and brake pushrod 12 passes through mounting hole, and its front end is from the inwall of cant board 22
On aperture in pass and act against braking fixture block 7 horizontal concrete chute 71 on.Axle is provided with the front end of brake pushrod 12
11 are held, roller etc. is may also set up, to reduce frictional resistance of the braking fixture block 7 in safety arrestment between brake pushrod termination.
Front apron 3 is fixed at the front port of the wedge-shaped slot of base 2, for stopping the braking fixture block 7 in wedge-shaped slot, is prevented
Fixture block is braked from the front port of wedge-shaped slot to deviate from.Front apron 3 can be the monoblock plate body of the Intermediate Gray gap shown in Fig. 1, also may be used
With two symmetric bodies separated in being.The middle gap of front apron 3 or the width at interval are greater than the thickness of brake disc, with
Just rotation work space is provided for brake disc.Fixing hole 33 is provided with the bottom of front apron 3, position is provided with the front end face of base 2
Be relatively fixed screw 23, uses fixing bolt, you can at the front port that front apron 3 is fixed on to base wedge-shaped slot.
Spacing cover plate 1 can be for setting up on cant board 21 along inner side and with the integrally formed cornice of base 2 or
Single cover plate.Spacing cover plate 1 shown in Fig. 1 is by the soft metal plate of two strips（Such as copper coin）Composition, each limit
Position cover plate 1 be fixed on cant board 21 on along top surface.Spacing cover plate 1 can also be the metal that copper bar is attached in its medial extremity
Plate.Each spacing cover plate 1 is fixed on the upper edge of a cant board 22 by fastener, and spacing cover plate 1 stretches out to inner side, its inner side
Along covering in the top of base wedge-shaped slot, fixture block is braked for block, prevents that brake fixture block deviates from from the top of wedge-shaped slot.Separately
Outside, the interior degree of stretching of spacing cover plate 1 is to make inner side along the braking fixture block beyond side where the spacing cover plate when initial position
Sandwich serface（But sandwich serface of braking fixture block when operating position can not be exceeded）, it is along to the inclined of brake disc by inner side that it, which is acted on,
The dynamic progress of rotation is spacing, prevents from touching braking fixture block 7 because brake disc deflection is rotated, causes to brake by mistake.
Under normal circumstances, brake activating mechanism 10 pushes down compression spring, and brake pushrod 12 does not touch braking fixture block 2, braking
Disk wheel along be able to two brake fixture block between service aisle along normal through.Work as generation（Brake failure of hoist engine etc.）
During emergency, system sends signal, disconnects the working power of this lock collar device, the release compression spring of brake activating mechanism 10, system
Dynamic push rod 12 is released forward rapidly in the presence of compression spring, promotes braking fixture block 7 to press to brake disc, the system of high-speed rotation
Moving plate drives braking fixture block 7 to be moved towards the portlet direction of wedge-shaped slot, so that by two by the frictional force between braking fixture block
The quick clip of braking fixture block 2 with laterally opposed motion is dead under individual lower wedge-shaped motion state, is achieved in the purpose of brake hard.
