Description
Technical field
The utility model relates to a kind of lifting rail device of handcart type breaker facility checkout vehicle, belongs to electric maintenance accessory appliances technical field.
Background technology
The middle high-tension switch cabinet is widely used in taking on the function of distributing electric energy in the Allocation transformer in industry-by-industry such as power plant, substation, industrial and mining enterprises, railway transportation, skyscraper and field, and circuit is carried out control, protection, monitoring etc.Moveable high-voltage switchgear is made up of control cabin, breaker chamber, bus-bar room and cable vault usually; The chamber internal fixation of breaker chamber has one group of stationary contact headstock as static contact head device, connecting with extraneous high-voltage power circuit into and out of the line static contact on the stationary contact headstock.When the handcart circuit breaker pushed in the breaker chamber, the upper and lower contact of handcart circuit breaker engaged respectively with into and out of the line static contact, behind the breaker closing, realized the connection on the circuit.When avoiding overhauling in the breaker chamber into and out of the charged personal safety that jeopardizes service personnel of line static contact, to valve be set corresponding to port part usually into and out of the line static contact, valve is opened when the handcart circuit breaker pushes in the breaker chamber; Otherwise when pulling out handcart circuit breaker execution maintenance, valve is closed, and uses shielding into and out of the line static contact.Join in cabinet and the maintenance process at the handcart circuit breaker, need usually the handcart circuit breaker to be delivered in the switch cubicle through the transhipment instrument.
Mainly constitute for mechanical transfer car(buggy) by the supporting plate that the handcart circuit breaker is held under casing and holder; The under casing bottom is equipped with wheel; The supporting plate on top is used to place the handcart circuit breaker, and the middle part is the connecting rod lifting mechanism, and this connecting rod lifting mechanism is formed adjusting its height and width by two groups of connecting rod mechanisms; Wherein one group of two connecting rod center is hinged; The front end of two connecting rods is hinged with supporting plate and under casing respectively, and the rear portion of two connecting rods is inserted in through locating dowel pin in the adjusting elongated slot of supporting plate and under casing, regulates height through the position that the adjusting locating dowel pin is regulated in supporting plate and under casing in the elongated slot to reach; And another is organized two connecting rods also the center is hinged, and the two ends of two connecting rods are installed in the adjusting elongated slot of two supporting plates through bearing pin respectively, and through the locating plate location.Though this kind is simple in structure, have good versatility, exist the loaded down with trivial details problem of operation, need two to three people operation usually, inefficiency.For the hydraulic pressure transfer car(buggy), the pallet bottom is equipped with hydraulic efficiency elevation structure, because hydraulic lifting need be equipped with two hydraulic actuating cylinder supporting trays; In the hydraulic lifting process, be prone to cause both sides asynchronous; And cause strong point overbalance, moreover this structure transfer car(buggy) is placed on transfer car(buggy) at the handcart circuit breaker; Promotion is comparatively required great effort when switch cubicle, and commonality is bad.
Summary of the invention
The purpose of the utility model provides a kind of manually control in the lifting rail process, can be at any time to the self-locking of lifting rail position, and compact conformation, reasonable, the lifting rail device of the handcart type breaker facility checkout vehicle of convenient and reliable operation.
The utility model is that the technical scheme that achieves the above object is: a kind of lifting rail device of handcart type breaker facility checkout vehicle, and comprise vehicle frame, be installed in gear reduction and catch gear and transmission device on the side stand with two side stands,
Described gear reduction comprises up-down handwheel, gear case, is installed in gear wheel shaft, at least one tween drive shaft and transmission shaft on the gear case; Driving gear on the gear wheel shaft is through intermediate gear on the tween drive shaft and the engagement of the transmission gear on the transmission shaft, and transmission shaft one side is extended gear case and is connected with drive sprocket;
Described catch gear comprises jam nut, T oblique crank Z cover, plain bearing and ratchet and pawl; The up-down handwheel is screwed in the T oblique crank Z and puts; And the up-down handwheel is spacing by the T shape end of T oblique crank Z cover, T oblique crank Z cover be screwed on the gear wheel shaft and be sleeved on the gear wheel shaft can axially movable plain bearing relatively, the shaft shoulder that is installed in ratchet one of which side and gear wheel shaft on the gear wheel shaft joins, opposite side is relative with the plain bearing end face; The ratchet and the ratchet that are hinged on the gear case join; Between gear case and the ratchet spring is installed, jam nut is captiveed joint with gear wheel shaft through the elasticity bearing pin, and the groove of the medial surface of jam nut and up-down handwheel is relative;
Described transmission device comprises drive sprocket, messenger chain, be installed on the vehicle frame gear shaft and by movable sprocket; The driven wheel of gear shaft both sides and the engagement of two tooth bars; Two tooth bars are connected with fixed guide with movable guiding rail respectively; The driven wheel shaft end is equipped with by movable sprocket, and messenger chain or driving band are installed in drive sprocket and by on the movable sprocket.
The utility model passes through transmission device behind the above gear reduction of two-stage; The gear shaft that is installed on the vehicle frame two stands is rotated; Because two driven wheels on the gear shaft and the engagement of two tooth bars; Therefore ability control and movable guiding rail and fixed guide are steadily done dipping and heaving, and the utility model adopts multi-stage gear to slow down, and operates light.The utility model catch gear adopts jam nut, T oblique crank Z cover, plain bearing and ratchet and pawl; Because ratchet is installed on the gear wheel shaft, the shaft shoulder of one of which side and gear wheel shaft joins, so when operation up-down handwheel rises; Can drive T oblique crank Z cover through the up-down handwheel moves forward along the screw thread on the gear wheel shaft; Promote plain bearing and move ratchet is crimped on the gear wheel shaft, the propulsive effort of up-down handwheel is reached on the gear wheel shaft through T oblique crank Z cover, plain bearing and ratchet, up-down hand gear control gear wheel shaft is rotated; And under the one-way effect of click, make the gear wheel shaft can backward rotation in rotation process.Because it is relative to be fixed on the groove of its medial surface of jam nut and up-down handwheel on the gear wheel shaft, when operation up-down handwheel descended guide rail, it is outwards mobile along the screw thread on the gear wheel shaft that the up-down handwheel drives T oblique crank Z cover; Make the shaft shoulder of plain bearing, ratchet out-of-gear axle, and up-down handwheel and T oblique crank Z cover withstand on the jam nut again, realize decline control fixed guide and movable guiding rail thereby up-down handwheel driven gear axle is rotated; When stopping that fixed guide and movable guiding rail descended control owing to can produce relative rotation between up-down handwheel and the gear wheel shaft, from and the shaft shoulder of plain bearing, ratchet and gear wheel shaft compressed; Gear wheel shaft can't be rotated, and reach the locking effect, therefore in operation fixed guide and movable guiding rail rising and decline process; All can reach self-locking at any time, compact conformation, reasonable, easy to operate, safety; Increase work efficiency, be applicable to multiple model such as VD4, VS1; VBI, 3AH-EP, the maintenance and the maintenance of the mid-cabinet breaker equipment of VEP.
