Embodiment
As shown in figure 1, the utility model includes the heavy wall cant board 22 that bottom plate 21 and two are oppositely arranged, bottom plate 21 and two
Individual cant board 22 is the integrally manufactured shaping of mild steel with high intensity, can keep maximum rigidity.Two cant boards 22 it is interior
Wall 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.Cant board 22
Middle part be thick section, be provided with thereon and wear the mounting hole for connecing brake activating mechanism.The mounting hole is through hole, and is a ladder
Circular hole, brake activating mechanism 10 is arranged in the mounting hole.
In Fig. 1, installing lock collar device of the present utility model includes braking fixture block 7, fixture block by wall support mechanism, needle roller cunning row
13rd, the part such as front apron 3, spacing cover plate 1, brake activating mechanism and this novel base.
Wherein, brake activating mechanism 10 is connected by compression spring with brake pushrod 12.Brake activating mechanism 10 can be
Electromagnet, hydraulic means or pneumatic means etc. can be dead electricity triggerings or obtain the working method of electric triggering.Braking
Trigger 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 cant board 22
Pass and acted against on the horizontal concrete chute 71 for braking fixture block 7 in aperture on inwall.
Braking fixture block 7 has symmetrical two, and the back side of braking fixture block 7 is horizontal slope, forms brake clip block body
Sphenoid.Two braking fixture blocks 7 are arranged in the wedge-shaped slot formed between two cant boards 22 on base 2 parallel, but
It is parallel brake disc passage between two braking fixture blocks.Friction plate 4 is provided with the sandwich serface of braking fixture block 7, in braking
The back side of fixture block 7 is provided with horizontal concrete chute 71.Bearing 11 is provided with the front end of brake pushrod 12, roller etc. is may also set up,
To reduce frictional resistance of the braking fixture block 7 in safety arrestment between brake pushrod termination.
The front end face of base 2 is plane, for fixing front apron.Front apron 3 is fixed on the front port of the wedge-shaped slot of base 2
Place, for stopping the braking fixture block 7 in wedge-shaped slot, prevents that brake fixture block deviates from from the front port of wedge-shaped slot.Front apron 3 can be
The monoblock plate body of Intermediate Gray gap shown in Fig. 1 or in separated two symmetric bodies.Slit the centre of front apron 3
Mouth or the width at interval are greater than the thickness of brake disc, to provide rotation work space for brake disc.Opened in the bottom of front apron 3
There is fixing hole 33, being provided with position in the front end face of base 2 is relatively fixed screw 23, uses fixing bolt, you can by front apron 3
At the front port for being fixed on 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.
