Seat 1012 is rotatablely connected, and the other end of right connection frame 108 is connected with the shaft for being rotatablely connected support frame 103 and right support 102,
The mounting rack 501 in compensation mechanism 5 of giving up the throne on gas bag 105 and right support 102 is rotatablely connected.
As shown in fig. 6, being equipped with tripping spring and piston inside gas bag 105, in braking process, tripping spring compression, which pushes, lives
Plug, piston is moved to the left together with mandril 104, when being passed through pressure source, mandril 104 is made to retract.
Now the working principle of carry compensation component 2 is described as follows:
When tooth engagement, thread bush 203 can not be rotated, and threaded rod 204 is passed through by top pillar 303, and top pillar 303 is stuck in sliding slot 3011
Interior, limitation threaded rod 204 rotates, and top pillar 303 can only move in sliding slot 3011, and threaded rod 204 and thread bush 203 pass through spiral shell
Line connection, when the first standstill face 2032 and the engagement of the second standstill face 2012, no relative rotation；
When closing lock, as shown in Figure 1, mandril 104 pushes the mounting rack 501 on left support 101 to move downward, and by unidirectional
Runner assembly 502 carries out the inverse time to limit the mounting rack 501 in the compensation mechanism 5 of giving up the throne on left support 101 with respect to left support 101
Needle rotation, rotates clockwise without limiting it, so can transmit torque to left support 101 in braking maneuver, makes left support 101
It is moved downward together with carry compensation component 2, until left friction plate 109 compresses brake disc 106, similarly, the right side on right support 102
Friction plate 1010 compresses brake disc 106, and into on-position, when friction plate is begun to wear out, mandril 104 will continue to make left support
101 move downward, when top pillar 303 moves to block 302 in sliding slot 3011, top pillar 303 and the movement of threaded rod 204 to the left
It is limited by truss 301, the first standstill face 2032 starts to get rid of the limitation of the second standstill face 2012 and disengage, thread bush at this time
203 can continue to move downward under the promotion of third elastic parts 202 with adjusting seat 201, and threaded rod 204 can be with thread bush at this time
203 relatively rotate, and until compensating friction disc wear amount, realize automatic compensation；
Supplementary explanation:
1, the engagement of the first standstill face 2032 and the second standstill face 2012 carries out circumferential limit, after geared surface disengages,
The not self-locking attribute of screw thread activates, and is able to carry out and rotates freely；
2, thread bush 203 is multiple thread, in the market with 3 to be common, due to increasing screw thread quantity, the spiral shell of single thread
Away from becoming more times, screw thread inclination angle becomes larger, and the self-locking function of screw thread disappears, and common multiple thread is circumferential without self-locking function, can
To be freely rotated, it is relatively conventional to carry out circumferential limitation for counterface tooth when use.
It moves back away from adjustment component 3, block 302 is fixed on the end of adjusting screw 304, and top pillar 303 can in sliding slot 3011
With movement, movable stroke is X, and X can be fixed on support frame 103 by adjusting 304 de-regulation of screw, truss 301, closes lock
When, according to above-mentioned analysis, as long as friction plate compensates automatically, top pillar 303 will be always close to block 302；When opening a sluice gate, pressed when being passed through
When power source, mandril 104 retracts, and internal system only has the restoring force of spring at this time, and third elastic parts 202 compresses, the first rotation stop
Face 2032 and the engagement of the second standstill face 2012, left support 101 can compensate under the action of the second elastic parts 1013 with carry
Component 2 moves right, and until the arrival of top pillar 303 side of the sliding slot 3011 far from block 302, moves back reach maximum value away from d at this time, i.e.,
Friction plate may wear to relieving to maximum from automatic compensation and move back away from corresponding top pillar 303 from block 302 to sliding slot 3011 far from block 302
Side distance X, so the arrangement achieves friction plate reset every time move back it is all constant away from d, and can also be by adjusting screw
304 adjusting X move back to control away from d.
For in each embodiment, the first elastic parts 4, third elastic parts 202 and the second elastic parts 1013 can be
Spring.
In use process:
1. close lock, such as Fig. 1, when left friction plate 109, right friction plate 1010 are begun to wear out, friction plate can moved back away from adjustment
Automatic compensation is completed under the drive of component 3；
2. after opening a sluice gate, if Fig. 2 does not need artificial manipulation, brake ontology 1 can be in the 2, first elasticity of carry compensation component
It automatically resets under the drive of component 4,
Due to the presence of carry compensation component 2 and compensation mechanism 5 of giving up the throne, the abrasion of left friction plate 109, right friction plate 1010
Caused left support 101, right support 102,501 differential seat angle of mounting rack can be made up on one-directional rotation component 502, also
It is to say how much is friction disc wear, left support 101, right support 102, mounting rack 501 will accordingly adjust how many angle, make to reset not
It is influenced by friction disc wear bring, holding is moved back away from constant, so both solves the problems, such as to automatically reset, and is also ensured multiple
The accuracy of position, maintains the effect of original braking.
Illustrate: when closing lock and referring to stuffiness, mandril 104 is released, and left friction plate 109, right friction plate 1010 compress brake disc
106, brake enters on-position；It opens a sluice gate to refer to that mandril 104 retracts under the action of gas bag 105, brake when being passed through pressure source
It unlocks the entrance state.
