Abstract
Provided is a falling prevention handcart crank assembly. The falling prevention handcart crank assembly comprises a handle, a handcart rocker arm, a bearing, a plurality of vacuum suction cups and a plurality of supporting arms, wherein the rear end of the handcart rocker arm is mounted outside the front end of a center shaft inside a cabinet through spring bayonet locks in a sleeved mode; the middle of the outer circumferential face of the handcart rocker arm is sleeved with a center hole in an inner ring of the bearing; the handle is in an L shape, and one end of the handle is fixed to the outer circumferential face of the handcart rocker arm; the vacuum suction cups are adsorbed to the position, located outside the center shaft, of the surface of the cabinet; one end of each supporting arm is connected to one vacuum suction cup, and the other end of each supporting arm is hinged to the outer circumferential face of an outer ring of the bearing. According to the falling prevention handcart crank assembly, the vacuum suction cups are combined with the supporting arms so that the handcart rocker arm can be horizontally fixed, in this way, the rear end of the handcart rocker arm cannot pop out or fall off in the shaking process, and therefore it is guaranteed that shaking operation can be smoothly carried out. In addition, the falling prevention handcart crank assembly has the advantages of being reasonable in structural design, simple, low in cost, easy to operate and the like.
Description
Technical field
The invention belongs to electric power overhaul equipment technical field, particularly relate to a kind of falling-proof type handcart rocking-handle assembly.
Background technology
Important power equipment in car switch Gui Shi transformer station is the switchgear that is widely used in 35kV and 10kV electric pressure.Car switch cabinet has operation, test and three kinds of positions of maintenance, wherein the switching between run location and test position needs operating personnel to drive handcart rocking arm 2 to rotate by shaking handle on the handcart crank shown in Fig. 11, then makes to be connected by spring detent 3 with handcart rocking arm 2 rear ends and axis 5 rotations that are positioned at rack 4 realize.When car switch cabinet is during in run location, the moving contact on it is connected with the fixed contact on bus; When car switch cabinet is during in test position, dynamic/static contact is separated.But in the handoff procedure of above-mentioned two kinds of positions, moving contact will experience electric discharge or charging process, so handcart crank 1 will guarantee fast, shake swimmingly and close or separated in the process of shaking, otherwise likely cause occurring the problem of dynamic/static contact calcination.
Because the handcart rocking arm 2 on certain model equipment exists easily loosening, caducous phenomenon in the process of shaking, thereby cause the car switch cabinet can not smooth and easy complete operation process shaking, in the process of shaking out, result not only can threaten the use safety of equipment, and has brought inconvenience to operation.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of falling-proof type handcart rocking-handle assembly.
In order to achieve the above object, falling-proof type handcart rocking-handle assembly provided by the invention comprises handle, handcart rocking arm, bearing, a plurality of vacuum cup and Duo Gen support arm; The axis front end that wherein rear end of handcart rocking arm is sleeved in rack by spring detent is outside; Centre bore on bearing inner race is sleeved on the outer circumference surface middle part of handcart rocking arm; Handle is L-shaped, and one end is fixed on the outer circumference surface of handcart rocking arm; A plurality of vacuum cups are adsorbed on the position that is positioned at axis outside 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.
Described vacuum cup and the quantity of support arm are 4, and evenly arrange in bearing 6 outsides.
Falling-proof type handcart rocking-handle assembly provided by the invention is to utilize the synergy of vacuum cup and support arm that handcart rocking arm level is fixed, and in the process of shaking, just can not eject, come off in its rear end like this, so can guarantee to shake carrying out smoothly of operation.In addition, this assembly also has reasonable in design, simple, cost is low, the advantages such as easy operating.
Accompanying drawing explanation
Fig. 1 is the car switch handcart crank portion structure schematic diagram cashier's office in a shop of prior art.
Fig. 2 falling-proof type handcart provided by the invention rocking-handle assembly structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, falling-proof type handcart rocking-handle assembly provided by the invention is elaborated.The parts identical with prior art adopt identical drawing reference numeral.
As shown in Figure 1, falling-proof type handcart rocking-handle assembly provided by the invention comprises handle 1, handcart rocking arm 2, bearing 6, a plurality of vacuum cup 7 and Duo Gen support arm 8; Axis 5 front ends that wherein rear end of handcart rocking arm 2 is sleeved in rack 4 by spring detent 3 are outside; Centre bore on bearing 6 inner rings is sleeved on the outer circumference surface middle part of handcart rocking arm 2; Handle 1 is L-shaped, and one end is fixed on the outer circumference surface of handcart rocking arm 2; A plurality of vacuum cups 7 are adsorbed on the position that is positioned at axis 5 outsides on rack 4 surfaces; One end of every support arm 8 is connected on a vacuum cup 7, and the other end is hinged on the outer circumference surface of bearing 6 outer rings.
Described vacuum cup 7 and the quantity of support arm 8 are 4, and evenly arrange in bearing 6 outsides.
Now falling-proof type handcart rocking-handle assembly using method provided by the invention is described below: when needs switch between run location and test position, operating personnel are turning handle 1 clockwise or counterclockwise, at this moment the handcart rocking arm 2 being connected with handle 1 will together rotate, then with the inner ring of dynamic bearing 6 and axis 5, also rotate together successively, complete thus that shaking of dynamic/static contact closed or separated.
