Technical Field

The invention relates to a lifting appliance, in particular to a motor base lifting appliance.

Background

In the machining process of the motor, the base needs to be transferred to a plurality of machining stations for a plurality of times, and meanwhile posture adjustment needs to be carried out on the base among different machining stations, namely, the horizontal base is transported or the vertical base is hoisted. Therefore, the lifting appliances required to be equipped in the production workshops of the motor manufacturers are various in variety and different in specification.

Such as the utility model patent document entitled "a motor base hanger" (CN 204355962U), the disclosed hanger comprises a first hanger plate 31 and a second hanger plate 32, the first hanger plate 31 and the second hanger plate 32 are made of elastic steel plates, the upper ends of the first hanger plate and the second hanger plate are hinged together in a way that the plate surfaces are parallel relatively through a U-shaped ring 2, first, the middle part of the second hanging plate is twisted by 90 degrees and the plate surfaces below the twisted position are opposite, the lower ends of the two hanging plates are lifting hooks for hooking workpieces, the first hanging plate is hinged with a first connecting rod 310, the first connecting rod 310 is provided with a plurality of limiting grooves 3101 in an arrangement manner along the length direction, the second hanging plate is hinged with a second connecting rod 320, the other end of the second connecting rod 320, which is far away from the hinged end, is provided with a locking pin 3201, and the locking pin and the limiting grooves are matched with each other and can realize blocking matching. The scheme provides two lifting points, which are suitable for lifting the base in a horizontal posture, namely the two bent parts 30 are correspondingly hooked on the radiating fins on the opposite sides of the horizontal base to carry out lifting.

The name is "motor frame hoist" (CN 212953855U), the bottom fixedly connected with locating piece 3 of hoist 2, the top fixedly connected with lug 4 of hoist 2, the outside of hoist 2 is provided with bulge 5, the inside threaded connection of bulge 5 has screw rod 6, the one end fixedly connected with cutting ferrule 7 of screw rod 6, the fixed hoisting point 8 of outside fixedly connected with of motor frame 1, the inside fixedly connected with protrusion round platform 9 of motor frame 1. Although the technical scheme can lift the motor base which is vertically arranged, the junction box outside the base is required to be utilized as a stress fulcrum, the other stress part is the inner wall of the base, and the inner wall is obviously not good as the stress fulcrum for the base with the processed inner wall, and the inner stress part and the outer stress part are concentrated on one side part of the base, if the base is too large in size and too heavy in weight, the base can be damaged, and the clamping sleeve 7 is supported on the protruding round table 9 fixedly connected inside the motor base 1 by adjusting the screw rod 6 during lifting, so that the lifting efficiency is seriously influenced.

In the patent document entitled "sling for motor base" (CN 105502152 a), two ends of the cross bar 10 are respectively clamped in the ports of the air ducts 21 correspondingly arranged at the inner wall of the port of the base 20 to support the base 20, thereby completing the transferring work of the base 20, and certainly, in the actual processing, the bar length D2 of the cross bar 10 is ensured to be between the inside distance D1 and the outside distance D2 of the two air ducts 21 correspondingly arranged, as shown in fig. 5; for the base 20 axially located in the horizontal direction, the hooks 12 on the lower portion of the cross bar 10 hang on the transfer rings 22 on the base 20. When the horizontal type base is lifted, the motor base is required to be provided with the transfer lifting rings 22, and when the vertical type base is lifted, the base is required to be provided with the port of the ventilation duct 21 which forms the support matching with the two ends of the cross rod 10.

Therefore, the lifting appliance in the prior art has various limitations, namely, the lifting appliance can only carry out the lifting of a horizontal or vertical base, and the lifting appliance which is not universally used for the lifting of the horizontal or vertical base is strictly limited by the structure of the base.

The rotating disc 20 is a circular ring disc, a radial outward convex part 21 is arranged at the disc edge, the third hinge shaft 13A is arranged at the convex part 21, a pin hole 15 penetrating through the disc surface is arranged at the disc edge of the top seat 10, a limit pin 40 is inserted into the pin hole 15, the limit pin 40 is positioned on the moving path of the convex part 21, and the convex part 21 circumferentially displaces to positions at two sides of the pin hole 15 for inserting the limit pin 40. The convex portion 21 is arranged to facilitate arrangement of the third hinge shaft 13A, and is matched with the limit pin 40, so that the rotation of the turntable 20 is limited, the limit pin 40 is required to be drawn out during transposition, the limit pin 40 is inserted after the transposition is completed, or the limit pin 40 is fixed on the top seat 10 and is inconvenient to take down, the turntable 20 can be shifted properly when the limit pin 40 is passed through the turntable 20, and then the turntable 20 is attached to the top seat 10.

At least two pin holes 15 are arranged at intervals, and the convex parts 21 are respectively positioned at the side of the area where the two pin holes 15 are positioned or between the pin holes 15 in the circumferential direction. The arrangement of at least two pin holes 15 at intervals herein is to ensure that the limiting pin 40 is inserted into the pin hole 15 to limit the two positions of the rotating disc 20; in addition, choose for use between pinhole 15 and the spacer pin 40 plug-in type cooperation mode compare the fixed scheme that sets up on footstock 10 of spacer pin 40, the transposition is adjusted more conveniently, because be connected with third jib 13 on the carousel 20, it is comparatively hard when axial displacement and circumferential direction carousel 20.

The two pin holes 15 are provided to match with a scheme that a C-shaped open ring 16 is arranged at the edge of the upper plate surface of the top seat 10 disclosed below, specifically, the pin holes 15 are arranged at the opening part of the open ring 16, and a circumferential spacing area between the first end 161 of the open ring 16 and the limit pin 40 and a circumferential spacing area between the second end 162 of the open ring 16 and the limit pin 40 form a circumferential limit area of the convex part 21.
