Description
Technical field
A kind of mechanism of manual operation machine is the utility model is related to, more particularly, to a kind of shaking manually with gravity protection
Mechanism of car.
Background technology
Some loads are heavier and self inertia and larger machine, such as die-cutting machine, gilding press are needed in maintenance or maintenance
Mode that will be manually carrys out rotary machine to carry out maintenance and inspection, or machine is left mechanical dead-centre position.It is common manual
Larry mode installs long handle spanner on final drive shaft, and machine rotating operation, this operation are carried out by pulling long handle spanner
Mode is not only laborious but also takes larger operating space, and has some potential safety problems.During larry, there is such as machine
Started by faulty operation and trigger the danger of operator's injury, another danger is, because the inertia of machine itself is larger, if shaking
The energy of operator is not concentrated during car, and the inertia of machine can drive larry handle quick rotation and hurt operator, this
Utility model has carried out effective improvement for disadvantages mentioned above.
Utility model content
The purpose of this utility model is exactly to provide a kind of band gravity in order to overcome the problems of the above-mentioned prior art and protect
The manual larry mechanism of shield.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of manual larry mechanism with gravity protection, for manual operation machine, the larry mechanism includes main biography
Moving axis, the larry mechanism further include pushing block, swing weight, limit switch and larry module；The larry module is placed in
On final drive shaft, one end of the swing weight is supported on pushing block, and the other end pushes down limit switch；The pushing block movement
During to setting position, drive larry module to carry out manual larry, at the same the one end for swinging weight depart from pushing block support and freedom
Fall and block pushing block and retract, the other end for pushing down limit switch is lifted, so as to drive limit switch to discharge, machine power-off, shakes
Car is in safeguard protection state.
The larry module includes gear set, central shaft, support base and larry handle, the gear set and central shaft
Connection, the pushing block are slided along central shaft, and the supporting seat frame is located at pushing block surrounding.
The gear set includes first gear and second gear, and the two is oppositely arranged；First gear is fixed on main biography
On moving axis, second gear and center axis connection, the pushing block are arranged on one end of second gear.
When the pushing block is moved on the inside of support base, first gear and second gear intermeshing are promoted, so that into one
Step drives central shaft to expose larry end, and at larry end, installation larry handle carries out manual larry；Swing at the same time one end of weight because
Gravity, which is fallen, blocks pushing block.
The larry mechanism further includes compression spring, and the pushing block is arranged on one end of second gear, and the compression spring is set
Put the other end in second gear.
The swing weight, which is equipped with, to be used to lift the weight handle for swinging weight, after terminating larry, the weight
Handle pushes, and swings one end that weight lifts and pushes down limit switch again, one end of whereabouts is lifted, and pushing block and second gear exist
It is ejected under the action of compression spring, makes mechanical recovery normal operation.
When the pushing block is on the outside of support base, pushing block covers the larry end of central shaft, and second gear is made be subject to compression spring
With being ejected, disengaged with first gear, while limit switch is pushed down in the one end for swinging weight, the other end is supported on pushing block, machine
Device is in normal operation.
The second gear is connected with central shaft using feather key.
The diameter of the first gear is more than the diameter of second gear.
Compared with prior art, the utility model has the following advantages：
1st, safeguard protection：Engaged by first gear with second gear, manual larry can be carried out after larry handle is installed, put
Dynamic weight causes machine to power off by blocking pushing block, release limit switch so that larry carries out in the state of safe enough；
2nd, it is time saving and energy saving：Second gear is connected with central shaft using feather key, with less larry spanner rotary middle spindle
One end can play labour-saving effect；
3rd, the machining accuracy of gear is reduced：When pushing block covers central shaft completely, larry spanner can not be installed, while the second tooth
Wheel is ejected same first gear by compression spring effect and disengaged, and is the normal operating condition of machine at this time, in this state the second tooth
Random device does not rotate wheel together, can reduce the friction of gear, reduce the machining accuracy of gear.
