Abstract
A kind of falling-proof type handcart rocking-handle assembly.It includes handle, handcart rocking arm, bearing, multiple vacuum cup and Duo Gen support arm；Outside the axis front end that wherein rear end of handcart rocking arm is sleeved in rack by spring detent；Centre bore on bearing inner race is sleeved in the middle part of the outer circumference surface of handcart rocking arm；Handle is L-shaped, and one end is fixed on the outer circumference surface of handcart rocking arm；The absorption of multiple vacuum cups is positioned at the position outside axis on rack surface；One end of every support arm is connected on a vacuum cup, and the other end is hinged on the outer circumference surface of bearing outer ring.The falling-proof type handcart rocking-handle assembly that the present invention provides is that handcart rocking arm level is fixed by the synergy utilizing vacuum cup and support arm, and so during shake, would not eject, come off in its rear end, it can be ensured that shake being smoothed out of operation.Additionally, this assembly also has reasonable in design, simple, low cost, it is easy to advantages such as operations.
Description
Technical field
The invention belongs to electric power overhaul equipment technical field, particularly relate to a kind of falling-proof type handcart crank
Assembly.
Background technology
Barrow type switchgear is the important power equipment in transformer station, is to be widely used in 35kV and 10kV electricity
The switchgear of pressure grade.Barrow type switchgear has operation, tests and overhaul three kinds of positions, wherein runs position
Putting the switching between testing position needs operator by the hands on the handcart crank shown in shake Fig. 1
Handle 1 drives handcart rocking arm 2 to rotate, then make to be connected by spring detent 3 with handcart rocking arm 2 rear end and
Axis 5 rotation being positioned at rack 4 realizes.When Barrow type switchgear is in run location, thereon
Moving contact is connected with the static contact on bus；When Barrow type switchgear is in testing position, dynamic/static contact divides
From.But in the handoff procedure of above two position, moving contact to experience electric discharge or charging process, so
Handcart crank 1 to ensure quickly during shake, shakes conjunction swimmingly or separate, and is otherwise likely to result in
The problem that dynamic/static contact calcination occurs.
Owing to the handcart rocking arm 2 on certain model equipment exists the most loosening, caducous during shake
Phenomenon, thus cause Barrow type switchgear smooth and easy can not complete operating process during shaking, shaking out, knot
Fruit not only can threaten the use safety of equipment, and brings inconvenience to operation.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of falling-proof type handcart crank group
Part.
In order to achieve the above object, the falling-proof type handcart rocking-handle assembly that the present invention provides includes handle, hands
Car rocking arm, bearing, multiple vacuum cup and Duo Gen support arm；Wherein spring is passed through in the rear end of handcart rocking arm
Outside the axis front end that bayonet lock is sleeved in rack；Centre bore on bearing inner race is sleeved on handcart rocking arm
In the middle part of outer circumference surface；Handle is L-shaped, and one end is fixed on the outer circumference surface of handcart rocking arm；Multiple vacuum
Sucker suction is positioned at the position outside axis on rack surface；One end of every support arm is connected to one
On vacuum cup, the other end is hinged on the outer circumference surface of bearing outer ring.
Described vacuum cup and the quantity of support arm are 4, and are uniformly arranged outside bearing 6.
The falling-proof type handcart rocking-handle assembly that the present invention provides is the associating utilizing vacuum cup and support arm
Handcart rocking arm level is fixed by effect, and so during shake, would not eject, come off in its rear end,
It can be ensured that shake being smoothed out of operation.Additionally, this assembly also has reasonable in design, letter
Single, low cost, it is easy to the advantages such as operation.
Accompanying drawing explanation
Fig. 1 is handcart crank portion structure schematic diagram on the Barrow type switchgear of prior art.
The falling-proof type handcart rocking-handle assembly structural representation that Fig. 2 present invention provides.
Detailed description of the invention
The falling-proof type handcart rocking-handle assembly provided the present invention with specific embodiment below in conjunction with the accompanying drawings enters
Row describes in detail.The parts identical with prior art use identical drawing reference numeral.
As it is shown in figure 1, the falling-proof type handcart rocking-handle assembly that the present invention provides includes that handle 1, handcart shake
Arm 2, bearing 6, multiple vacuum cup 7 and Duo Gen support arm 8；Wherein the rear end of handcart rocking arm 2 is passed through
Outside axis 5 front end that spring detent 3 is sleeved in rack 4；Centre bore suit on bearing 6 inner ring
In the middle part of the outer circumference surface of handcart rocking arm 2；Handle 1 is L-shaped, and one end is fixed on outside handcart rocking arm 2
On periphery；Multiple vacuum cups 7 adsorb and are positioned at the position outside axis 5 on rack 4 surface；Often
One end of root support arm 8 is connected on a vacuum cup 7, and the other end is hinged on outside bearing 6 outer ring
On periphery.
Described vacuum cup 7 and the quantity of support arm 8 are 4, and uniformly set outside bearing 6
Put.
Now the falling-proof type handcart rocking-handle assembly using method that the present invention provides is described below: when needs exist
When switching between run location and testing position, operator can turn clockwise or counterclockwise
Fixed handle 1, the handcart rocking arm 2 being at this moment connected with handle 1 will together rotate, band dynamic bearing 6 the most successively
Inner ring and axis 5 rotate the most together, thus complete dynamic/static contact shake conjunction or separate.
