Description
Technical field
The invention belongs to motor assist equipment technical fields, are used for more particularly to a kind of from the locked of locked motor
Release device.
Background technology
Driving motor is installed in the walking mechanism of bridge maintenance equipment, which has auto-lock function, and one is disconnected
Stop power supply, motor will be automatically locked under the action of brake block, can ensure the safety of equipment operation in this way, power
Electric machine main shaft will drive the sprocket wheel being mounted on main shaft under normal circumstances, and then entire walking mechanism is driven to walk.
But in power blackout situation or power supply trouble, just need to start man-operated mechanism at this time, drive entire vehicle with walking machine
Structure, and the sprocket wheel on electric machine main shaft is also a part for man-operated mechanism at this time, in During manual operation, it is also desirable to electric machine main shaft
Free rotation, due to power-off, motor self-locking, electric machine main shaft can not normal rotation at this time, it is necessary to release its brake block.
And original releasing mechanism is single-point operation, operating personnel is needed, which to hold unlocking mechanism always, can just make its rotation,
One it is disconnected unclamp, and can restore locked, result in this way man-operated mechanism can not normal use, therefore, it is necessary to design it is a kind of be used for from
The locked releasing device of locked motor.
Invention content
The object of the present invention is to provide a kind of locked releasing device being used for from locked motor, this device can easily exist
Freely switched between electric model and manual mode.
In order to achieve the above objectives, designing scheme of the invention is：A kind of locked releasing device being used for from locked motor, it
Including motor body, the head of the motor body is equipped with outer housing by screw, and the outer housing is internally provided with motor
Main shaft, the end of the electric machine main shaft are equipped with sprocket wheel, and the sprocket wheel is mounted on by locking nut locking on electric machine main shaft, institute
It states and self-locking brake block is installed on electric machine main shaft, the top vertical of the self-locking brake block is welded with operation loop bar, the operation
Internal thread is machined with inside loop bar, sliding slot, the operation loop bar are machined on the outer housing where the operation loop bar surface
Internal thread on operating lever is equipped with by thread fitting, the operating lever is machined with outer spiral shell with the matched head of internal thread
Line, being slidably installed in the operating lever has locking sliding sleeve, and the lower end of the locking sliding sleeve is provided with locking catch, the lock
Tight catch can coordinate with the outer end face of limiting stand terrace, and rubber sleeve is fixedly mounted in another end of the operating lever.
Spring is set between locking sliding sleeve and rubber sleeve outside the operating lever.
The self-locking brake block can not rotate electric machine main shaft locking under motor power blackout situation, the self-locking brake block
Along sliding slot to sprocket wheel direction pull when electric machine main shaft will be in the unlocked state, can sprocket wheel drive under be freely rotated.
The sprocket wheel, by chain engaged transmission, can be rotated with hand chain wheel by hand chain wheel with movable sprocket.
The method have the advantages that：
1st, in the case of motor is in normal power supply, self-locking brake block is located at the normal position of motor, it will be in the unlocked state, at this time
By electric machine main shaft band movable sprocket normal rotation, and then drive walking mechanism normal walking.
2nd, it when motor is under power blackout situation, just needs to start manual operation mode at this time, and under manual operation mode, chain
Wheel is a part for manual transmission, needs sprocket wheel that can also freely rotate, it is necessary to which electric machine main shaft can also freely turn
Dynamic, i.e., self-locking brake block is in motor solution lock-bit, only needs to pull the rubber sleeve at the top of operating lever, and then self-locking is driven to stop at this time
Vehicle piece is moved to B displacements, while the outer end face for locking catch and limiting stand terrace is fitted, the position of operating lever is locked in B
Position, so that it may which so that self-locking brake block is in the unlocked state always, then the spring by being sleeved in operating lever pushes operating lever
Locking, ensure its will not upward sliding, and then electric machine main shaft is enable freely to rotate, at this time, it is only necessary to operate man-operated mechanism
It can smoothly band movable sprocket and electric machine main shaft rotate, and then walking mechanism normal walking is operated by manual mode.
3rd, by outer housing process sliding slot can be conveniently operated bar drive self-locking brake block move freely, and then conveniently
Operation to self-locking brake block.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is overall structure diagram of the present invention.
In figure：Motor body 1, power cord 2, outer housing 3, rubber sleeve 4, operating lever 5, locking sliding sleeve 6, electric machine main shaft 7, chain
Wheel 8, locking nut 9, locking catch 10, external screw thread 11, limiting stand terrace 12, self-locking brake block 13, operation loop bar 14, internal thread
15th, screw 16, sliding slot 17；
A：The normal position of motor, during energization motor can normal rotation, when power-off will be in locking state；Self-locking is stopped under normal conditions
Vehicle piece can all be in this position.
B：Motor solution lock-bit under power blackout situation, to unlocking motor, then needs to pull self-locking brake block and is always positioned at this position
It puts, just motor can be freely rotated, and then unlocks, for operation in a manual mode, need to remain self-locking brake position
In this position.
Specific embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
Fig. 1 is participated in, a kind of locked releasing device being used for from locked motor, it includes motor body 1, the motor body
