Description
Technical field
The present invention relates to power supplying and distributing equipment technical field, more particularly, to a kind of handcart switch cabinet electric rocking handle.
Background technology
Handcart switch cabinet has operation, wherein three positions of experiment and maintenance, cutting between running position and testing position
Changing needs operating personnel handcart rocking arm to be driven to rotate by shaking the handle on handcart crank, then makes to lead to handcart rocking arm rear end
Cross that spring detent is connected and central axis in cabinet is realized.Operating personnel rotate crank, drive screw rotation, so as to
It is moved forward and backward switchgear trolley.When Barrow type switchgear is in running position, the static contact on moving contact and busbar thereon
Connection；When Barrow type switchgear is in testing position, dynamic/static contact separation.But in the handoff procedure of above two position, move
Contact will undergo electric discharge or charging process, thus handcart crank to ensure during shake it is quick, swimmingly shake conjunction or separation,
Otherwise it is likely to result in the problem of dynamic/static contact calcination occur.Since the handcart rocking arm in certain model equipment is during shake
In the presence of easy loosening, caducous phenomenon, so as to which Barrow type switchgear be caused smooth cannot to complete to operate during shaking, shaking out
As a result journey can not only bring inconvenience to operation, but also threaten the safe to use of equipment.When switchgear, which exists, to be latched, by
In the firmly different of each operating personnel, someone may overexert moment, and then destroys locking while damaged switch
The construction of cabinet.When stopping busbar operation, artificial hand switchgear trolley, time-consuming and laborious, inefficiency.Big, the matter for some volumes
Measuring big switchgear trolley, to depend merely on a people hand very painstaking.
Chinese patent notification number CN204156387U discloses a kind of handcart switch cabinet electric rocking handle, it includes having defeated
Go out the driving device of shaft and the specialized barrel for being connected to switchgear trolley；The output revolving shaft and specialized barrel of driving device
It is connected, the output revolving shaft of driving device can drive specialized barrel to rotate；The rotation of specialized barrel can driving switch cabinet it is small
Vehicle moves, and switchgear trolley is made to reach operating position；It is provided in driving device and turn-takes counter and can show turnning circle
Display screen is additionally provided with the button of control driving device output revolving shaft start and stop in driving device.Driving device includes having output
The electric tool and gearbox of shaft, are provided with gearbox between electric tool and specialized barrel, the output revolving shaft of gearbox with
Specialized barrel is connected, and the side of electric tool is equipped with horizontal side handle.The device improves behaviour using electric device
Awkward situation during work, still, since the dynamic/static contact of wheelbarrow switch needs larger power, the knot of the present apparatus during division
Structure is but in the change distribution environment of a large amount of women staff works, due to being convenient in gripping and stress, it is impossible to preferably be applied.
Invention content
In view of this, in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of handcart switch cabinet electric rockings
Using the method for setting handle, solving the prior art and be not easy to hold and the drawbacks of stress, while realize to pacify
Dress, manual and electric dual-purpose effect.
In order to achieve the above objectives, the present invention uses following technical scheme：
A kind of handcart switch cabinet electric rocking handle, including rocking arm, rocking arm both ends set handle and crank head, feature respectively
It is：The crank head includes being placed in the electric structure of rocking arm side and bidirectional ratchet mechanism, the planet tooth of rocking arm opposite side
Mechanism and tube-in-tube structure are taken turns, the tube-in-tube structure is in front end, the planetary gear construction setting and bidirectional ratchet inside configuration；
The tube-in-tube structure includes sleeve part and guidance part, and the sleeve part is cooperation handcart-type switch handcart crank mouth
Inside has the common structure of square opening, and the guidance part is fixed on the outside of sleeve part square opening；The guidance part inner wall setting
Arc groove, arcuately ecto-entad tapers into the arc groove size, until each side tail end of the arc groove is contracted in sleeve
The corner end of mouth square groove；
The bidirectional ratchet mechanism includes annular rack, gear, pawl, handle ratchet wheel and outer ratchet；The gear and pawl
It is fixedly connected, the annular rack is cylindrical shape, and rack is located on ring section, is changed by rotary annular rack drives gear
Become pawl direction, handle ratchet wheel and outer ratchet is made to run simultaneously forward or backwards；The outer ratchet is fixedly connected with sleeve part；
The planetary gear mechanism includes internal gear, planetary gear and external toothing, and the external toothing is fixedly connected with handle ratchet wheel；
The electric structure is set to rocker handle side, and including motor and power supply module, the motor connects internal tooth
Wheel；The rocking arm is additionally provided with locking pin, and the locking pin realizes consolidating for handle ratchet wheel or external toothing and rocking arm by pin shaft structure
It is fixed.
Further, the pawl setting makes it keep the resetting spring of operating position.
Further, the handle setting rubber grip, the rubber grip set dot bulge.
Further, at least a pair of of arc bump of setting in the sleeve-port, the arc bump lower part sets spring.
The beneficial effects of the invention are as follows：
The present invention is used in crank head guidance part, is guided by the rotation of arc groove, is made to set on switch cabinet handcart axis
Rectangular stressed member can quick insertion sleeve mouth, make crank that can be optionally plugged into handcart stressed member in any angle, operate
It is convenient.
By bidirectional ratchet mechanism, on the one hand it can be rotated at random guide ring, particular, it is important that can be by adjusting
There is provided the ratchet annular rack significantly marked, can effectively prevent operating personnel due to business is unskilled or psychological stress etc. because
Element, carrying out negative direction rotation leads to equipment damage or is unable to exact operations.
Motor drive mechanism and planetary gear mechanism cooperation, by smaller driving force, realization needs could completing for large force
Switching on/off handcart movement；When motor drive mechanism driving force is insufficient or electricity is inadequate, locking pin connecting rocker arm and handle ratchet wheel are used
Or external toothing, use the manual operation present apparatus.
