Description
Technical field
The utility model relates to a kind of traction lifting device, relates in particular to a kind of heat-dissipation traction lifting device of being convenient to, and this traction lifting device can be to adopt the various traction lifting devices of motor as propulsion source, for example draws cucurbit.
Background technology
Electric block is mainly used in and promotes or the traction object; Mainly comprise electrical motor, be arranged on the operation reductor on the service meter, be arranged on the cucurbit outer cover of service meter below; Be arranged on the reel in the cucurbit outer cover; The suspension hook group that is arranged on cucurbit outer cover below constitutes, and is installed with electrical motor on the cucurbit outer cover, is provided with reductor in the cucurbit outer cover.Like the patent No. is the Chinese utility model patent " a kind of electric block " of ZL201020629621.3 (notification number is CN201882839U); Reaching the patent No. is the Chinese utility model patent " a kind of electric cucurbit " of ZL200920296981.3 (notification number is CN201605125U), and they have all disclosed the structure of electric block.The prior electric cucurbit is generally used as large-scale lifting appliance; And be fixed on certain eminence and use, generally only use as upwards drawing object, however a lot of occasion; As needing the traction object in the factory building or on the road, the prior electric cucurbit has been used with regard to being inconvenient to so.
To the deficiency of aforementioned present situation, the applicant has invented a kind of portable hand-held electric block, comprises the shell with handle, and the rear end of shell is equipped with aft hook; First support and second support, they are parallel to each other and are spaced apart and arranged in the shell; Wheel hub rotatably is supported between said first support and second support, is wound with rope on the said wheel hub, and the front end that the free end of rope passes shell links to each other with front hook; Motor is supported between said first support and second support, and the axially spaced-apart certain distance of this motor and said wheel hub, and the output shaft of this motor is in transmission connection through reduction gearing mechanism and said wheel hub and rotates with drive hub.
It no matter is large-scale or portable traction lifting device; It all adopts motor as propulsion source, and motor is a core component, and the quality of motor radiating directly influences the service life of motor; Therefore be equipped with louvre on the motor housing; Again because of motor generally is installed in the housing, for the heat that will give out from the louvre of motor housing can rapidly and efficiently shed outside the housing, general those skilled in the art can expect on housing, also being provided with louvre.Its shortcoming is; Extraneous foreign matter can enter into from the louvre of housing in the housing; And then the drive disk assembly of influence or damage enclosure interior, set up louvre on the housing in addition, the noise of motor can pass through louvre; The opening that reaches traction lifting device sidepiece goes out to diffuse out, and causes the excessive defective of noise in the product use.
Existing in addition traction lifting device is not provided with antiwind structure; Steel wire cable in the existing wheel hub is freely to arrange in turning course; Steel wire cable is rambling arranges and can cause in the electric block steel wire cable to be overlapping and at random, causes producing very big friction drag between the steel wire cable, causes the wearing and tearing of steel wire cable; Also easily because of twining confusion, the inhomogeneous steel wire cable stuck phenomenon that produces; Cause steel wire cable revolution not smooth, use inconveniently, and arrange owing to steel wire cable is disorderly and unsystematic and to reduce the length that wheel hub holds steel wire cable.
The utility model content
The utility model technical matters to be solved is to provide a kind of to need not on shell, to be provided with the heat-dissipation of being convenient to that louvre also can be fast sheds internal heat outside the housing and draw lifting device to above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of heat-dissipation traction lifting device of being convenient to comprises shell; Wheel hub rotatably is supported in the said shell, is wound with rope on the said wheel hub, and the fixed end and the wheel hub of rope are fixed, and the free end of rope passes the opening of shell front end and links to each other with front hook; Aft hook, itself and shell relative fixed also expose outside the rear end of shell; In order to the drive hub motor rotating, to fix in the enclosure, the housing of motor is provided with louvre; It is characterized in that: comprise that also inside has the radiating shell of heat dissipation channel; Have the perforation that the housing of profile and motor matches on the radiating shell; Has the import that is communicated with said heat dissipation channel on the hole wall of perforation; The opening of the outlet adjacent housings front end of heat dissipation channel, said radiating shell is through boring a hole sheathed and being fixed on the housing of motor, and the louvre on the housing of motor is positioned at the import on the perforation hole wall.
