Abstract
The utility model discloses a circuit breaker handcart propulsion guiding mechanism. The circuit breaker handcart propulsion guiding mechanism comprises a switchgear body frame and a handcart rack. The handcart rack is internally provided with a handcart lead screw propulsion mechanism. The bottom of the handcart rack is provided with walking wheels. The frame side walls at two sides of the handcart rack are provided with horizontally arranged rollers. The inner walls at two sides of the switchgear body frame are provided with fixed guide rails which are matched with the rollers. The rollers can enter the fixed guide rails and can horizontally move in the fixed guide rails. After the structure provided by the utility model is adopted, the rollers can enter the fixed guide rails, and the handcart rack is guided through the guide rails. Not only can accurate alignment between a moving contact and a static contact be obtained for eliminating a defect of incapability of aligning the moving contact with the static contact, but also the circuit breaker handcart propulsion guiding mechanism has advantages of: simple structure, simple and laborsaving operation, large bearing force, accurate action, remarkable use reliability improvement, and convenient mounting and maintenance.
Description
Technical field
The utility model relates to a kind of parts of direct-current switch cabinet, and specifically a kind of circuit breaker cart advances guiding mechanism.
Background technology
Existing domestic direct-current switch cabinet and high-voltage switch cubicle handcart propulsion mode adopt the mode such as leading screw screwing mechanism and direct push-in type, realize the movement of handcart between test position and service position, to realize the moving contact that is arranged on handcart and the fixed contact closed and disconnected in hyperbaric chamber.Adopt existing these two kinds of structures all to have many shortcomings, although for example leading screw screwing mechanism action is accurate, operation Portable power saving, supporting power is limited, is not suitable for heavier handcart, and complex structure easily damages, unfailing performance is lower, manufacturing cost is higher; Although directly push-in type is simple in structure, manufacturing cost is lower, operation precision is poor, operation effort, load-bearing also can not be very greatly, easily other spacing interlocking elements are caused to damage while operating simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of simple in structure, operation Portable power saving, bearing capacity are large, action accurately, reliability wants high, the simple circuit breaker cart of installation and maintenance to advance guiding mechanism.
In order to solve the problems of the technologies described above, circuit breaker cart of the present utility model advances guiding mechanism, comprise frame of switch cabinet body and handcart vehicle frame, in handcart vehicle frame, be provided with handcart leading screw propulsive mechanism, the bottom of handcart vehicle frame is provided with road wheel, on the frame side wall of handcart vehicle frame both sides, be provided with horizontal roller, be provided with the fixed guide coordinating with roller on the inwall of frame of switch cabinet body both sides, roller can enter into also can horizontal movement in fixed guide in fixed guide.
The porch of described fixed guide is provided with and can makes roller enter into guiding surface.
The bottom surface of described fixed guide is arrived the distance between road wheel bottom to the height between ground a little more than idler wheel bottom.
Adopt after above-mentioned structure, the fixed guide arranging on the inwall of the roller arranging on the frame side wall due to handcart vehicle frame both sides and frame of switch cabinet body both sides, can make thus roller enter in fixed guide, lead by guide rail rival car vehicle frame, not only can make moving contact and fixed contact contraposition accurate, eliminate the defect that moving contact can not be aimed at fixed contact, and simple in structure, simple to operate laborsaving, bearing capacity is large, action is accurate, improved dependability, and installation and maintenance are also very convenient.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram that the utility model circuit breaker cart advances guiding mechanism;
Fig. 2 is the local mounting structure schematic diagram that the utility model circuit breaker cart advances guiding mechanism.
Embodiment
Below in conjunction with the drawings and specific embodiments, advance guiding mechanism to be described in further detail to circuit breaker cart of the present utility model.
As shown in the figure, circuit breaker cart of the present utility model advances guiding mechanism, comprise frame of switch cabinet body 1 and handcart vehicle frame 2, in handcart vehicle frame 2, be provided with feed screw nut's propulsive units 3, handcart leading screw propulsive mechanism 3 makes moving contact contact with fixed contact, action accuracy is high, operation Portable power saving, the bottom of handcart vehicle frame 2 is provided with road wheel 4, on the frame side wall of handcart vehicle frame 1 both sides, be provided with horizontal roller 5, on the inwall of frame of switch cabinet body 1 both sides, be provided with the fixed guide 6 coordinating with roller 5, roller 5 can enter in fixed guide 6 and can horizontal movement in fixed guide, the bottom surface of fixed guide 6 is arrived the distance between road wheel 4 bottoms to the height between ground a little more than roller 5 bottoms, make road wheel depart from ground certain altitude, facilitate the reliability of operation.
Further can be provided with and can make roller 5 enter into guiding surface 7 in the porch of fixed guide 6, facilitate thus handcart vehicle frame to advance in fixed guide 6, the convenience of its use is further enhanced.
