Abstract

The utility model relates to an electric chain hoist which is assembled into integration by a whole hoist sling lifting chain mechanism (1), a housing (2) for a cycloid pin wheel planetary speed reducer and a disc type brake motor (3), wherein, the input end surface of the speed reducer is tightly fixed on the end closure of the rotating shaft of the motor, and the rotating shaft (4) of the motor is the primary transmission shaft of the speed reducer; the wallboard of the frame body of the hoist sling lifting chain mechanism is fixedly installed on the output end surface of the housing (2) of the speed reducer, and a five-toothed major axis (7) is the output shaft of the speed reducer. The utility model has the advantages of compact structure, legerity and beautiful appearance, and the weight and the cost of the utility model are not increased far more than that of an existing hand pulling hoist, however, use function and efficiency are improved.

Description

Electric chain hoist

The utility model relates to a kind of portable electric loop chain cucurbit.

Existing loop chain cucurbit all is a chain block generally, needs the lifting of manpower slide fastener during use, and efficient is low, labour intensity is big; Being seen in the market electric block structure is all more numerous and diverse, bulky, and very heavy, the occasion of interim construction is carried and is used in inconvenience.

The purpose of this utility model is to disclose a kind of simple in structure, portable electric loop chain cucurbit that volume is light and handy, easy to use.

This novel cucurbit is the same with the structure of existing electric block, also include electrical motor, retarder and cucurbit chain sling mechanism, but different is, it is not to be electrical motor, retarder and cucurbit chain sling mechanism make up simply, but be an integral body with the support body of cucurbit chain sling mechanism and the housing and the assembling of disc type brake electrical motor of cycloidal pinwheel planetary gear speed reducer, the input end face of cycloidal pinwheel planetary gear speed reducer is fastening to be mounted on the disc type brake shaft of motor end cap face, with the disc type brake shaft of motor is the primary drive shaft of retarder, the primary drive gear that is about to cycloidal pinwheel planetary gear speed reducer is fitted on the disc type brake shaft of motor, the support body of cucurbit chain sling mechanism is packed on the output end face of cycloidal pinwheel planetary gear speed reducer housing, the core hole of the input end of five tooth major axis in the cucurbit chain sling mechanism and the final stage output wheel of cycloidal pinwheel planetary gear speed reducer is equipped, and the reversing gear that installs on the mouth of five tooth major axis meshes with the plate gear of control chain sling sprocket wheel commutation.

The disc type brake electrical motor is a kind of more new-type axial field electric motor makes, its stator and rotor are to be made of two plate-like iron cores, brake hoop is housed on the rotor, half of the serial same specification electrical motor of the also not enough Y of axial dimension size, be particularly suitable for frequently, usually the propulsion source of the mechanical equipment of emergency braking as starting.The utility model is used as power with the disc type brake electrical motor, be equipped with deceleration component in the cycloidal pinwheel planetary gear speed reducer and the chain sling mechanism components reasonable combination in the chain block, make complete machine structure very compact, light and handy, attractive in appearance, it is compared with chain block with existing, how many complete machine weight of the present utility model and productive costss can't increase, but functions of use and efficient improve greatly.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:

Fig. 1 is the utility model main frame structural representation partly;

Fig. 2 is the machine shape structural representation.

The utility model substantive features are exactly a kind ofly to combine with disc type brake electrical motor (3) and cycloidal pinwheel planetary gear speed reducer, have substituted the new product that cover in the chain block pulls chain-wheel mechanism.The disc type brake electrical motor is as approved product existing sale on market.In the utility model, the rotating shaft (4) of disc type brake electrical motor (3) can be directly as the primary drive shaft in the retarder.Though retarder of the present utility model also can use the slowing-down structure of other type, the high performance that cycloidal pinwheel planetary gear speed reducer is simple in structure because of it, volume is small and exquisite, the speed drop ratio is big, transfer torque is big naturally should be optimal selection.The housing of cycloidal pinwheel planetary gear speed reducer (2) can directly utilize the rotating shaft face end cap of disc type brake electrical motor (3) as its input end cover plate, the primary drive gear of cycloidal pinwheel planetary gear speed reducer (5) can be fitted in the rotating shaft (4) of disc type brake electrical motor (3), simultaneously, again with the wallboard of cucurbit chain sling mechanism support body (1) directly as the mouth cover plate of cycloidal pinwheel planetary gear speed reducer, the input end of five tooth major axis (7) in the cucurbit chain sling mechanism can be fitted in the core hole of final stage output wheel (6) of cycloidal pinwheel planetary gear speed reducer, as the output shaft of cycloidal pinwheel planetary gear speed reducer.So just, those unnecessary connecting device parts in the middle of can saving make complete machine structure more compact.Cucurbit chain sling mechanism in the utility model partly still can use conventional gauge member.Reversing gear (11) on its five teeth major axis (7) mouth still directly is meshed with two plate gears (10) and (12) that the sprocket wheel (9) of control chain sling (8) commutates by the original design mode, turning to of its sprocket wheel (9), that is the rising and falling of suspension hook (13), just turn to direct control by disc type brake electrical motor (3).
