Abstract
The invention belongs to the technical field of hoisting equipment, and particularly relates to a multifunctional electric hoist. The multifunctional electric hoist comprises a hoisting electric motor and a running electric motor; the hoisting electric motor is connected with a hoisting mechanism speed reducer, the running electric motor is connected with a running speed reducer; the hoisting mechanism speed reducer is connected with a reel device, and a hoisting hook device is connected below the reel device; and the running speed reducer is connected with an electric trolley. The multifunctional electric hoist is characterized in that the reel device is connected with the hoisting hook device through a balance beam, and the hoisting electric motor is connected with a fire cut-off limiting stopper; and a limiting rod is arranged on the reel device, and stop blocks are arranged on the limiting rod. The multifunctional electric hoist has the beneficial effects that brake is reliable, and the gliding distance can be effectively controlled; after being started, the electric hoist can be stopped, and when reaching the limiting position, the electric hoist can be effectively controlled to be stopped; a hoisted weight can be effectively prevented from shaking in air; and the multifunctional electric hoist is reasonable in design, compact in structure, safe, reliable, and easy to use and popularize.
Description
(1) technical field
The invention belongs to technical field of crane equipment, particularly a kind of multifunctional motor-driven cucurbit.
(2) background technology
Electric block for monorail crane, rotating arm crane, double-beam trolley and manual mono beam overhead crane in bridge type, have structure simple, to manufacture and maintenance is convenient, interchangeability is good, processing ease, hang the advantages such as thing convenient transportation is quick, be widely used in lifting transport weight in factory.But the electric block under prior art exists many defects: it is unreliable to brake, distance of glide easily exceedes regulation requirement; After startup, can not stop, or during to end position, still not stop; Motor temperature is too high, too fast; Retarder sound is excessive; These shortcomings have had a strong impact on the normal use of electric block, bring greatly hidden danger to production safety.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of reasonable in design, compact conformation, safe and reliable multifunctional motor-driven cucurbit.
The present invention is achieved through the following technical solutions:
A kind of multifunctional motor-driven cucurbit, comprise lifting electric motor and service meter, lifting electric motor is connected with Hoist Mechanism, service meter is connected with operation retarder, Hoist Mechanism is connected with roll device, cargo hook gear is connected with under roll device, run retarder and be connected with motor-driven carrier, it is characterized in that: described roll device is connected by equalizing bar with between cargo hook gear, lifting electric motor is connected with circuit fire stop, roll device is provided with position-limited lever, position-limited lever is provided with stop piece.
Described equalizing bar is provided with two symmetrical balance wheels.
Described roll device side is connected with flexible-cable introducer.
Described lifting electric motor is connected with electric appliance control box respectively with service meter.
Described roll device is connected with rope guide device.
The invention has the beneficial effects as follows: braking is reliable, effectively can control distance of glide; After startup, can stop, during to end position, effectively can control it and stop; Can effectively prevent lifted weight thing from rocking aloft; Reasonable in design, compact conformation, safe and reliable, be easy to promote the use of.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is main TV structure schematic diagram of the present invention;
Accompanying drawing 2 is left TV structure schematic diagram of the present invention;
In figure, 1 lifting electric motor, 2 service meters, 3 Hoist Mechanism, 4 run retarder, 5 roll devices, 6 cargo hook gears, 7 motor-driven carriers, 8 equalizing bars, 9 circuit fire stops, 10 position-limited levers, 11 stop pieces, 12 balance wheels, 13 flexible-cable introducers, 14 electric appliance control boxes, 15 rope guide devices.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises lifting electric motor 1 and service meter 2, lifting electric motor 1 is connected with Hoist Mechanism 3, service meter 2 is connected with operation retarder 4, Hoist Mechanism 3 is connected with roll device 5, roll device is connected with cargo hook gear 65 times, run retarder 4 and be connected with motor-driven carrier 7, be connected by equalizing bar 8 between roll device 5 with cargo hook gear 6, lifting electric motor 1 is connected with circuit fire stop 9, roll device 5 is provided with position-limited lever 10, position-limited lever 10 is provided with stop piece 11.Equalizing bar 8 is provided with two symmetrical balance wheels 12.Roll device 5 side is connected with flexible-cable introducer 13.Lifting electric motor 1 is connected with electric appliance control box 14 respectively with service meter 2.Roll device 5 is connected with rope guide device 15.
Adopt a kind of multifunctional motor-driven cucurbit of the present invention, weight to be lifted is hung on cargo hook gear 6, start lifting electric motor 1, drive Hoist Mechanism 3 thus drive roll device 5 to rotate, by heavy lift to required correct position; Then startup optimization electrical motor 2, drives and run retarder 4, thus driving electric dolly 7 runs to assigned address forward.Be connected with equalizing bar 8 above cargo hook gear 6, symmetrically again on equalizing bar 8 be provided with two balance wheels 12, steady in operational process of lifted weight thing can be ensured, excessive rocking can not be produced, thus ensure that the safety of underperson.When reaching the limit of position, start circuit fire stop 9, this timer quits work, but owing to also having inertia, can walk on, the stop piece 11 on position-limited lever 10 can play the effect of brake, makes it stop in time, prevents accident.Flexible-cable introducer 13 can by incomes such as all electric wires wherein, the danger preventing the friction in device working process or clamp electric wire and catch fire.Rope guide device 15 further ensure that the stationarity of cargo hook gear 6 in lift heavy thing process.
