Abstract
The utility model discloses a lifting device for a motor rotor and relates to a device for lifting a large-scale motor rotor, aiming to overcome the shortcomings of the traditional lifting device such as more types, heavy dead weight, material wastes, storing space occupation, and potential safety hazards. The lifting device provided by the utility model comprises a lifting rod, a sleeve fixed on the lifting rod, and a liner bushing mounted in the sleeve, and is characterized in that a group of round holes are uniformly formed on the lifting rod; a positioning bolt is arranged along the radial direction of the sleeve; and the liner bushing is fixed in the sleeve via the positioning bolt. In the utility model, the lifting device can be flexibly adjusted according to the diameter of the extend end of a rotor shaft, so that the requirement to the type of the lifting device of the rotor is greatly reduced when various motors are manufactured, the space for placing the lifting device can be saved, the material is reduced, the dead weight of the lifting device is light, and the use is safe.
Description
Technical field
The utility model relates to a kind of rotor suspender, relates to a kind of rotor suspender that is used for the hanging large-scale electric motor rotor specifically.
Background technology
At present, the suspension rod that the used suspender of each enterprise's hanging large-scale electric motor rotor all adopts the monoblock steel plate or is welded by several sections steel plates welds a sleeve then at suspension rod one end, and a kind of rotor shaft extension diameter of axle is joined a kind of suspender, and a kind of suspender is joined a lining.Its shortcoming is that 1. suspender is many, and 2. lining is many, and 3. suspender and lining be from great, waste material, and hanger and lining slide easily when 4. lifting, and cause the damage of personal injury and workpiece, 5. take production site.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of manufacture craft that provides is simple, and material-saving is in light weight, a kind of rotor suspender that applicability is strong.
Technical solution of the present utility model is: the rotor suspender comprises suspension rod and the sleeve that is fixed on the suspension rod, and be contained in lining in the sleeve, it is characterized in that: suspension rod is provided with equally distributed one group of circular hole, along sleeve radially be provided with a bolt, lining is fixed in the sleeve by bolt.
Lining described in the technical solution of the present utility model is made up of one group of copper sheathing.
Be fixed with reinforcement between suspension rod described in the technical solution of the present utility model and the sleeve, be fixed with the balance steel pipe on the suspension rod.
Be processed with one group of circular hole that loss of weight is used on the suspension rod of the present utility model, and this group circular hole also is simultaneously the lifting hole(eyelet) of lifting usefulness, can be during operation according to the weight and the size of the rotor that lifts, select the different circular hole of suspension hook, to keep the rotor axial level, suspension ring can not skid during the light and lifting rotor of suspension rod like this, improve the fail safe in the hoisting process; The utility model to adapt to the different diameters of axle, can reduce the particularly quantity of suspension rod of suspender because the lining in the rotor suspender sleeve is adopted one group of copper alloy bushing combination, saves the suspender placing space of production scene; Be processed with a screwed hole on the sleeve of the present utility model, all be processed with a through hole on corresponding each lining, during lifting suitable lining put into sleeve after, position with bolt, lining just can not skid off like this, in order to avoid cause workpiece and personal injury.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in Figure 1, 2, suspender mainly includes suspension rod 1, sleeve 4, bolt 5 and lining 6, the shape of suspension rod 1 is down " L " font, adopts Numerical control cutting by the monoblock steel plate, or by two and be welded with upper steel plate, on the upper surface of suspension rod 1, be provided with one group of equally distributed circular hole, be used to alleviate the weight of suspension rod 1, simultaneously this group circular hole also be the lifting usefulness lifting hole(eyelet), during use according to the lifting rotor weight and size, select different circular holes, to keep the level of rotor axial; Sleeve 4 is weldingly fixed on the lower end of suspension rod 1, lining 6 is sleeved in the sleeve 4, along sleeve 4 radially be processed with a screwed hole, be fixed with bolt 5 in the screwed hole, radially be provided with and the corresponding through hole of sleeve 4 upper screwed holes along lining 6, lining 6 is made up of one group of copper sheathing; Be welded with reinforcement 3 between sleeve 4 and the suspension rod 1, also be welded with steel pipe 2 on the suspension rod 1, in the process of lifting rotor, can be by the level of steel pipe 2 fine setting rotors; When using the utility model lifting rotor, size according to the actual rotor shaft diameter, select suitable lining 6 to pack in the sleeve 4, suspension hook is hooked in the circular hole above Fig. 1 suspension rod 1, then suspender lining 6 is enclosed within on the rotor shaft extension, choose the length of bolt 5 as required, guarantee that bolt 5 heads can not expose the inwall of lining 6, in order to avoid the scuffing armature spindle, and bolt 5 locked, and according to the overall dimension and the weight of rotor, adjust the suspension hook position, rotor can be sling, in the hoisting process, can be by steel pipe 2 fine setting rotor levels.
Claims (3)
1. rotor suspender, comprise suspension rod (1) and be fixed on sleeve (4) on the suspension rod (1), and be contained in lining (6) in the sleeve (4), it is characterized in that: suspension rod (1) is provided with equally distributed one group of circular hole, along sleeve (4) radially be provided with a bolt (5), lining (6) is fixed in the sleeve (4) by bolt (5).
