Method used

Double-drum lifting hoist structure of the present invention as shown in Figure 1 and Figure 2, rope reel assembly and transmission assembly are housed on the frame, rope reel assembly comprises: reel 7, is contained on the reel 7 The rope 9 and the reel shaft 6 that links to each other with the reel 7 are equipped with gear D respectively. The transmission assembly includes a motor 1, a first-stage reduction mechanism 2 connected to the motor 1, and a drive spindle 3 connected to the first-stage reduction mechanism 2. The gear A outside the frame is mounted on the drive spindle 3, and the gear A and the drive shaft are mounted on the frame. The driven gear B mounted on the driven shaft 4 on the top is engaged, and the driven gear B is meshed with the steering gear C on the steering shaft 5 mounted on the frame. The steering gear C meshes with the gear D mounted on the spool shaft 6 , and the driven gear B meshes with the gear D mounted on the spool shaft 6 . The drum 7 is equipped with a rope guide 8, which makes the steel wire rope tighten and loosen regularly. When the two rope guides move to both sides, the wire rope is released, the electric hoist descends, and when the two rope guides move to the middle, The wire rope is tightened, and the electric hoist goes up. The first-stage deceleration mechanism 2 is a flexible rim member floating on the sun gear and the planet carrier. After the motor 1 decelera...

Abstract

The invention relates to a dual-drum elevator. A gear (D), a steering gear and a driven gear are installed on one drum shaft. Ropes are installed on drums. Drum shafts are connected with the drums. A gear (D) is installed on the other drum shaft. A first-stage speed reducing mechanism is connected with a motor. A driving main shaft is connected with the first-stage speed reducing mechanism. A gear (A) outside a rack is installed on the driving main shaft. The gear (A) is engaged with two driven gears which are respectively installed on two driven shafts on the rack. One driven gear is engaged with the steering gear which is installed on a steering shaft on the rack. The steering gear is engaged with the gear (D) which is installed on one drum shaft. The other driven gear is engaged with the gear (D) which is installed on the other drum shaft. The dual-drum elevator provided by the invention has the advantages that the transmission ratio is large, the structure is compact, the twisting force is large, the transmission is stable, the noise is low, the goal of safely and reliably lifting objects is achieved, the effect of synchronous lifting is realized, the dual-drum elevator can be widely used in the construction industry, the gantry crane industry and the door industry, the size is small and the service life is long.

Example Embodiment

[0008] The structure of the double-drum hoist of the present invention is as follows figure 1 with figure 2 As shown, the frame is equipped with a rope reel assembly and a transmission assembly. The rope reel assembly includes: a reel 7, a rope 9 mounted on the reel 7, and a reel shaft 6 connected to the reel 7 are respectively equipped with gears D. The transmission assembly includes a motor 1, a first-stage reduction mechanism 2 connected to the motor 1, and a drive spindle 3 connected to the first-stage reduction mechanism 2. The gear A outside the frame is mounted on the drive spindle 3, and the gear A is mounted on the frame The driven gear B mounted on the driven shaft 4 gnaws together, and the driven gear B meshes with the steering gear C on the steering shaft 5 mounted on the frame. The steering gear C meshes with the gear D installed on the reel shaft 6, and the driven gear B meshes with the gear D installed on the reel shaft 6. A rope guide 8 is installed on the reel 7. The rope guide makes the wire rope regular tightening and loosening. When the two rope guides move to both sides, the wire rope is released and the electric hoist descends. When the two rope guides move to the middle, The wire rope is tightened and the electric hoist rises. The first-stage reduction mechanism 2 is a floating flexible rim member of the sun gear and planet carrier. After the motor 1 decelerates and increases the torque through the first-stage reduction mechanism 2, the second deceleration increases the torque, so that the elevator can increase the torque at the same time. Obtain a larger transmission ratio. The double-drum hoisting machine of the present invention realizes that the rotation of the motor 1 drives the first-stage reduction mechanism 2 to rotate, so that the gear A mounted on the driving main shaft 3 rotates, the driven gear B drives the steering gear C to rotate, and the driven gear B , The steering gear C drives the gear D to rotate, the gear D drives the reel shaft 6 to rotate, and the reel shaft 6 drives the reel 7 to rotate, so that the rope 9 on the reel 7 rises or descends with the animal body for synchronous take-off and landing movement. A motor drives two reels with the same rotation speed and opposite rotation directions. The first-stage reduction mechanism is designed as a flexible rim structure with floating sun gear and planet carrier. The load is evenly distributed between the planet wheels and reduces the gnawing time. Dynamic load reduces noise and has good stability, so as to achieve the purpose of lifting objects with large transmission ratio, compact structure, strong torsion force, stable transmission, low noise, and safety and reliability. Synchronous lifting is achieved in the construction industry, door The crane and door industry can be widely used, with small size and long service life.
