Description
One, technical field
The present invention relates to a kind of propulsive mechanism of handcart, specifically a kind ofly be applied to electric railway in the electric railway electric substation with indoor single-phase vacuum circuit breaker handcart advancing mechanism.
Two, background technology
Along with the continuous expansion of track traffic, electric railway has also obtained using widely.The primary cut-outs that adopt in the electric substation of electric railway more.The mesolow power distribution cabinet is mainly used in power plant and the industrial and mining enterprises, the mesolow power distribution cabinet adopts the propulsive mechanism of Worm-gear type, pinion and-rack more, and the characteristics of this type of circuit breaker are that volume is little, and are in light weight, higher apart from ground, the operator only need simply shake handle can drive the circuit breaker motion.
The lever propulsive mechanism is mainly used in primary cut-out.The characteristics of this type of circuit breaker are that volume is big, the layout of in light weight and open type.When adopting the lever propulsive mechanism, the operator need utilize lever principle to pull handle, and drives the leverage effect that places the circuit breaker cart below by connecting rod, produces actuating force and drives the circuit breaker cart motion.The shortcoming of this lever propulsive mechanism is: transmission stability is poor, and transmission efficiency is low; The entire mechanism volume is big, rigidity is little; Use inconvenience, operation is hard.
Three, summary of the invention
The purpose of this invention is to provide a kind of electric railway with indoor single-phase vacuum circuit breaker handcart advancing mechanism, this propulsive mechanism adopts cross joint to realize the transmission of moment, reliable transmission, easy to operate, laborsaving.
The objective of the invention is to be achieved through the following technical solutions:
A kind of electric railway is with indoor single-phase vacuum circuit breaker handcart advancing mechanism, it is characterized in that: it comprises power transmission shaft, bearing, connecting lever, main shaft, end plate and roller, power transmission shaft by bearing fixing below circuit breaker cart, one end of power transmission shaft is the six square end heads suitable with the sleeve rocking arm, the cross joint that the other end of power transmission shaft is formed by two connecting levers is connected with main shaft, and drives the main shaft rotation when power transmission shaft rotates; Main shaft is by bearing fixing close track place below circuit breaker cart, be equipped with end plate at the main shaft two ends, be provided with roller on end plate, roller is installed in the block that is fixed on the circuit breaker cart frame, and drive circuit breaker cart frame seesaws when main shaft rotates.
For reaching best transmission effect, among the present invention, the cross joint that described two connecting levers are formed is connected and is positioned at the centre position of main shaft with main shaft, like this when power transmission shaft rotates, just can drive main shaft smoothly rotates, and finally drive whole circuit breaker cart frame and seesaw, be used for overcoming the pulling-inserting force of circuit breaker dynamic/static contact, make things convenient for circuit breaker cart primary circuit and electrical network deciliter.
Operation principle of the present invention is as follows: power transmission shaft is fixed in the handcart below by bearing, axle sleeve etc., and end is one or six square end heads, the sleeve rocking arm of conveniently packing into operation.During operation, rotate six square end heads with rocking arm and produce torque, the cross joint of forming by two connecting levers is delivered to main shaft, and main shaft is rotated, and main shaft is by bearing fixing close track place below circuit breaker cart, and an end plate respectively is equipped with at two ends, and roller is housed on the end plate.Be fixed in the reaction force that the block of frame produces by roller contact whole frame seesawed, seesaw thereby drive whole circuit breaker cart, realize the dynamic and static contact of circuit breaker deciliter.
Compared with prior art, advantage of the present invention is: transmission stability is good, the transmission efficiency height; The entire mechanism volume is little, rigidity is big; Easy to use, rapid operation.
Beneficial effect of the present invention is as follows:
Reliable transmission, transmission efficiency height, the present invention adopts the cross joint to realize the transmission of moment, compares with the lever propulsive mechanism, and transmission is stable, the transmission efficiency height, entire mechanism rigidity is higher.
Interchangeability is good, and each parts of the present invention are all realized modularization, does not have welding and riveted joint, can dismantle easily, changes and adjust.
Easy to operate, the rocking arm that adopt to be equipped with need not turnover, in 60 degree scopes, can realize circuit breaker deciliter.And it is more laborsaving than lever.
Occupy little space, general mechanism occupation space only is 1/5th of a lever mechanism.
Cost is low, and each parts of the present invention only need simple processing, and being equipped with cheap standard component can assemble.Compare with Worm-gear type, pinion and-rack, cheap.
