Description

special flexible belt sliding type 90-degree overturning lifting appliance for medium and large motors

Technical Field

The utility model relates to a motor hoist technical field especially relates to a special soft area slidingtype 90 upset hoists of medium and large-scale motor.

Background

When the motor is packaged, according to the requirement of stability of the motor placement, the motors have different installation modes (some motors need to be placed horizontally and some motors need to be placed vertically), for example, for a B5 motor, the installation mode during packaging mainly adopts vertical placement, and the vertical placement is stable when the B5 motor is packaged; but all motors above 160mm (the central height of the motor base in the motor) are horizontally laid after the assembly and the paint spraying are finished, and the manual operation is mainly adopted at present when the motors above 160mm are packaged: step one, a motor is hung on a packaging chassis, and then the motor is turned over manually, so that the vertical packaging of the motor is realized (the number of workers is required, wherein the motor with the smaller size of 160mm-200mm needs 1 person for operation, the motor with the larger size of 225mm-250mm needs 2 persons for operation, and the motor with the larger size of 280mm-355mm needs 3-5 persons for operation). Therefore, the manual turning has the following disadvantages: 1. the labor intensity of workers is high, and in addition, when the motor needs to be turned by multiple persons, the potential safety hazard of the persons is great due to different force applied by each person; 2. the operation stability is poor during manual turnover, and small accidents that the surface of the motor is easily collided and scratched by paint on the surface and the like to influence the product quality are easily caused in the operation process. 3. The operation wastes time and labor, and the benefit is lower.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an avoid not enough among the background art, design one kind can carry out 90 directions safe and stable upsets of axial to the motor, and the commonality is good moreover, safe in utilization simultaneously, high benefit a special soft area slidingtype 90 upset hoists of medium and large-scale motor.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

The utility model provides a special soft area slidingtype 90 upset hoists of medium and large-scale motor, includes pulley support and lifting rope, pulley support is "Jiong" font, the cover is equipped with the pulley shaft on the axis body that is equipped with pulley shaft and pulley shaft between two side boards of pulley support is equipped with the pulley, one side end fixed mounting of lifting rope has first lifting hook, opposite side end fixed mounting to have the second lifting hook after passing the pulley, install the rope length between pulley stopper and second lifting hook on the rope body of lifting rope and be less than the rope length between pulley stopper and first lifting hook, collude on the gib head of second lifting hook and be equipped with motor rear axle head fixer. During hoisting: firstly, hooking a first hanging ring on a pulley bracket by a lifting hook of a crane; then, a mounting seat in the rear motor rear shaft head fixer is in inserting fit with the rear motor shaft head, and the locking bolt is screwed after being aligned with the rear shaft head fan blade key groove; hooking a second lifting ring in the rear shaft head fixing device of the rear motor by using a second lifting hook, and hooking the motor lifting ring by using the first lifting hook; then starting the crane to slowly lift the horizontal motor (B5 motor), wherein the motor hoisting ring is a main stress point, the mass of the motor (the front end part of the motor) at the front part of the main stress point is greater than that of the motor (the rear end part of the motor) at the rear part of the main stress point, at the moment, the front end of the motor is declined, and meanwhile, the rear end of the motor is upwards inclined under the pulling of the hoisting rope until the pulley stopper is contacted with the pulley, so that the motor is approximately vertically inclined; then move the motor to the place of installation to start the loop wheel machine and descend the motor slowly (because the motor is the slope, when the motor slowly descends to being close to the installation department, need carry out artifical fine setting and realize that the motor erects the installation) and accomplish the hoist and mount of motor from lying to erectting, make the motor erect and place in the packing, whole process is simple, safety, quick.
