Abstract
The utility model discloses a hoist of a double-lifting-system skip car for blast furnace charging. The key point is that the hoist comprises a left coiling block and a right coiling block, wherein an intermediate coupler is connected between the left coiling block and the right coiling block; a left drive device is arranged at the left side of the left coiling block; a right drive device is arranged at the right side of the right coiling block; the left drive device and the right drive device are symmetrically arranged about the intermediate coupler. According to the hoist of the double-lifting-system skip car for blast furnace charging, two coiling blocks are adopted for greatly reducing the deflection of a steel rope, so that the service lives of the coiling blocks, the steel rope and a head sheave are favorably prolonged; due to the adoption of two drive devices, the reliability is improved, the cost is reduced, and the blast furnace charging can be better ensured; the hoist is a novel hoist of a large-size skip car charging system.
Description
Technical field
The utility model relates to a kind of winch.
Background technology
Existing high furnace truck hoister only has a set of reel system, and it is by a roll device, and a set of actuating device (it comprises: electrical motor, retarder, coupler, drg, master controller) or two cover actuating devices drive.When above-mentioned arbitrary parts et out of order needs to safeguard, maintenance, while changing, truck can not material loading, is difficult to guarantee that blast furnace normally produces, and will cause heavy economic losses.
The utility model content
The purpose of this utility model is to provide a kind of charging of blast furnace double lifting system skip hoist with two cover jacking systems.
The utility model is achieved in that a kind of charging of blast furnace double lifting system skip hoist, it is characterized in that: described winch has comprised left reel and two reels of right reel, between its left reel and right reel, with intermediate shaft coupling, is connected; The right side that the left side of left reel is provided with left actuating device, right reel arranges right actuating device.Described left actuating device and right actuating device are symmetrical arranged about intermediate shaft coupling, its left actuating device comprises the Left Drive retarder, the high speed shaft of Left Drive retarder and slow-speed shaft are all two shafts, and the left axle of left reel is connected with an end of the slow-speed shaft of Left Drive retarder by Left-wing Federation's axial organ; The other end of the slow-speed shaft of Left Drive retarder is connected with left control setup, and Left Drive motor, Left Drive drg are arranged on respectively the two ends of Left Drive high-speed shaft of speed reducer, and the Left Drive motor is connected by left high-speed coupling with the Left Drive retarder;
Right actuating device comprises right gearing speed-reducer, and the high speed shaft of right gearing speed-reducer and slow-speed shaft are all two shafts, and the right axle of right reel is connected with an end of the slow-speed shaft of right gearing speed-reducer by right coupler; The other end of the slow-speed shaft of right gearing speed-reducer is connected with right control setup, and right driving motor, right transmission brake are arranged on respectively the two ends of right gearing speed-reducer high speed shaft, and right driving motor is connected by right high-speed coupling with right gearing speed-reducer.
Left high-speed coupling and right high-speed coupling all adopt flexible coupling.
The utility model has adopted two cover elevator system, and the drum shaft of two cover elevator system connects with coupler, and when a set of (electrical motor, retarder, drg) et out of order is changed, the actuating device of the other end still can guarantee 70% charge material loading; Electrical motor, drg are arranged on respectively the two ends of high-speed shaft of speed reducer, and driving, braking torque shunting, improved high speed shaft extension strained condition, can increase the service life; Adopt two cover coders to be arranged on respectively retarder slow-speed shaft two ends, can from automatically controlled, than failure-free, take signal.Adopt flexible coupling between electrical motor, retarder, reliability is high, long service life.Owing to adopting two reels to promote respectively two trucks, not only drum diameter is less, and load torque reduces, and has reduced manufacturing cost; And the steel cable drift angle is smaller, can extend the service life of steel cable; In the time of can also realizing changing a dolly or overhaul its skew bridge track, an other dolly maintains material loading.
The utility model is owing to changing a reel into two reels, and drum diameter reduces, and the torque of driving system also reduces, and the steel cable drift angle is smaller, can extend the service life of steel cable; Changing a large motor into two small machines again and can reduce manufacturing cost, improve the safety in operation of blast-furnace skip car, is the ideal style of blast-furnace skip car winding plant.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is left control setup, 2 is the Left Drive retarder, 3 is Left-wing Federation's axial organ, and 4 is left reel left shaft holder, and 5 is left reel, 6 is left reel right bearing seat, 7 is intermediate shaft coupling, and 8 is right reel left shaft holder, and 9 is right reel, 10 is right reel right bearing seat, 11 is right coupler, and 12 is right gearing speed-reducer, and 13 is right control setup, 14 is right transmission brake, 15 is right high-speed coupling, and 16 is right driving motor, and 17 is the Left Drive motor, 18 is left high-speed coupling, and 19 is the Left Drive drg.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, utility model is further described
As shown in Figure 1, between left reel 5 and right reel 9, with intermediate shaft coupling 7, be connected; The high speed shaft of Left Drive retarder 2 and right gearing speed-reducer 12 and slow-speed shaft are all two shafts, and the left axle of left reel 5 is connected with Left Drive retarder 2 by Left-wing Federation's axial organ 3; The right axle of right reel 9 is connected with right gearing speed-reducer 12 by right coupler 11; Left reel left shaft holder 4, left reel right bearing seat 6, right reel left shaft holder 8 and right reel right bearing seat 10 all adopt double-row self-aligning roller bearing; Left Drive motor 17, Left Drive drg 19 are arranged on respectively the two ends of Left Drive retarder 2 high speed shafts, right driving motor 16, right transmission brake 14 are arranged on respectively the two ends of right gearing speed-reducer 12 high speed shafts, right driving motor 16 is connected by right high-speed coupling 15 with right gearing speed-reducer 12, Left Drive motor 17 is connected by left high-speed coupling 18 with Left Drive retarder 2, and two cover coders are arranged on respectively slow-speed shaft one end of Left Drive retarder 2 and right gearing speed-reducer 12.Reel adopts Plate Welding.
