Abstract
The invention belongs to distribution equipment and relates to a handcart advancing mechanism of a breaker of a direct-current switch cabinet, which is used in a handcart type direct-current switch cabinet. The mechanism comprises a driving shaft and a driven shaft which are mutually vertical; the front end of the driving shaft is connected with a driving crankarm; a driven crankarm with a U-shaped structure is connected on the driven shaft, the bottom of the U-shaped structure of the driven crankarm is articulated with the driving crankarm by an articulated shaft, and the axis of the articulated shaft is vertical to the axis of the driven shaft; meanwhile, the axis of the articulated shaft and the axis of the driving shaft have an included angle; the two flanks of the U-shaped structure of the driven crankarm are arranged at both sides of the radial direction of the driven shaft, and the driven shaft and the two flanks of the driven crankarm are connected in a penetrating way by a penetrating pin; both ends of the driven shaft are fixedly provided with a swing arm respectively; and meanwhile, a component which can obstruct the swing of the swing arms is arranged on a cabinet body of the switch cabinet. The invention has simple structure, good reliability, strong bearing capacity, laborsaving operation and high motion accuracy.
Description
Technical field
The invention belongs to controller switching equipment, relate to a kind of for the handcart advancing mechanism of breaker of direct-current switch cabinet in direct-current switch cabinet.
Background technology
In existing handcart-type direct-current switch cabinet and high-tension switch cabinet, the mode that handcart pushes the propelling of stroke latter end adopts the modes such as leading screw screwing mechanism and direct push-in type usually, and these modes all exist very large defect.For leading screw screwing mechanism, although its action comparatively accurately, operation Portable power saving, supporting power is limited, is difficult to be applicable to very heavy handcart, and high, the easy damage of its complex structure, manufacturing cost, poor reliability; And for direct push-in type, although structure is simple, manufacturing cost is lower, its operation precision is poor, operation effort, load-bearing also can not very greatly, easily cause damage to other spacing interlocking elements when operating simultaneously.
Summary of the invention
Technical problem to be solved by this invention is, provides the handcart advancing mechanism of breaker of direct-current switch cabinet that a kind of structure is simple, good reliability, bearing capacity are strong, rapid operation, operation precision are high.
Handcart advancing mechanism of breaker of direct-current switch cabinet of the present invention includes and is arranged on a driving shaft on handcart and a velamen moving axis; The axis of driving shaft is parallel with handcart direction of propulsion, and it can rotate under the operation of external force, and driving shaft front end is connected with an initiatively connecting lever; Driven axle is positioned at driving shaft front, the axis of driven axle is vertical with drive axis, driven axle is connected with a passive connecting lever, passive connecting lever is " U-shaped " structure, passive connecting lever is hinged by a jointed shaft in the bottom of its " U-shaped " structure and active connecting lever, the axis of this jointed shaft and the axes normal of driven axle, meanwhile, the axis of jointed shaft and the axis of driving shaft have an angle; Two flanks of " U-shaped " structure of passive connecting lever are placed in the radial both sides of driven axle, and driven axle is connected with two flank cross-under of passive connecting lever by the cross-under pin that radial direction runs through driven axle; The two ends of driven axle are respectively fixed with a swing arm, are provided with the parts that can stop that swing arm swings on the cabinet of switch cubicle simultaneously.The outer rim of swing arm is provided with the roller of an outstanding swing arm plane, switch cabinet body both sides are provided with fixing draw-in groove simultaneously, the roller moved horizontally with handcart can enter draw-in groove from the breach of draw-in groove side, when swing arm swings roller leave draw-in groove gap position and stop by draw-in groove.
Structure of the present invention is simple, manufacture and easy for installation, rotation can be converted into rectilinear movement, thus complete progradation by tool into rotation driving shafts such as rocking arms, and its rapid operation, operation precision be high, can bear heavier load.
Accompanying drawing explanation
Fig. 1 is perspective view of the present invention;
Fig. 2 is the structural representation of the present invention when handcart is not advancing to the position;
Fig. 3 is the structural representation of the present invention when handcart is advancing to the position.
Embodiment
Reference numeral comprises: driving shaft 1, driven axle 2, initiatively connecting lever 3, passive connecting lever 4, jointed shaft 5, cross-under pin 6, swing arm 7, roller 8, draw-in groove 9, breach 10.
The course of work of the present invention when handcart advances is: first handcart is directly pushed cabinet, the roller 8 moved horizontally with handcart enters draw-in groove 9 from breach, at this moment rotating driveshaft 1, driving shaft 1 drives initiatively connecting lever 3 to rotate, because the jointed shaft 5 between active connecting lever 3 and the passive connecting lever 4 of " U-shaped " structure and driving shaft 1 have an angle and jointed shaft 5 is vertical with driven axle 2, therefore passive connecting lever 4 can be driven to produce the rotation that is rotating shaft with driven axle 2, thus drive driven axle 2 around the axis rotation perpendicular to driving shaft 1, swing arm 7 then swings with the rotation of driven axle 2, the relative distance between the roller 8 in swing 7 and driving shaft is so just made to change, and now depart from the breach 10 of draw-in groove because roller 8 highly changes, spacing and draw-in groove cannot be departed from by draw-in groove 9 institute because of roller 8, therefore the power pulling driving shaft 1 and handcart to move forward just is created, handcart is advancing to the position.
