The remote-controlled lifting device for buildings is provided with a lifting assembly and a telescopic bracket, and a fixed pulley is installed on the bracket. The utility model is provided with a movable pulley with a hook by a wire cable. The lifting assembly comprises an electric motor and worm transmission speed reducer driven by the electric motor, and a remote control switch and a manual control switch are connected with the power lead of the electric motor in parallel. The utility model has the advantages of simple structure and convenient operation. The remote control lifting device for buildings can lift heavy articles with 30 kg weight, 500 kg weight to 1000 kg weight. The lifting height is 30 to 40 meters. Especially, the remote control lifting device for buildings can be started in a remote control mode, and can be also started manually, and the remote control lifting device for buildings is a small portable necessary article for high-layer buildings.

Description

Remote-controlled hoist for building

The utility model belongs to a kind of hoisting device, particularly a kind of building remote control Jack.

The people of inhabitation high-rise building is more and more now, and do not develop into elevator up to ten layers at general regional building yet, eight layers own with regard to not charged ladder from designing with storied building, most of regional three gas are not perfect again, use the resident of honeycomb briquette and petroleum oil liquid gas storage tank to occupy significant proportion in high-rise building.General family (the particularly above family of five floors) also often needs upper and lower building carrying article, and floor is high more, and the difficulty of upper and lower building carrying article is big more.

For solving the difficulty of high-rise building carrying article, what have in the prior art installs the shaking Jack at building balcony, the design that also has the electric hoisting device, " domestic miniature motor hoist " as the CN2078312U bulletin, it has a triangular framing, lift system by minitype motor driving is installed on triangular framing, article is mentioned by the steel rope that lift system drives.Whole lift system is installed on the triangular framing, and the basis of framework is again a hinges, therefore, its load-carrying capacity is little, and owing to use the line traffic control switch, use also very inconvenient, or upstairs, two people are used downstairs, or the round process of having finished heavy articles upstairs, downstairs of a people, bring a lot of troubles to the user.

The purpose of this utility model is to overcome the deficiencies in the prior art part, for disturbing, the upper and lower building carrying of high-rise building resident article row solves problem, reduce labour intensity, a kind of two cover lifting modes that have are provided, operate steadily, the reliability height, both can manually boot, again the building remote control Jack of remote-controlled startup.

The utility model is achieved in that

It has a hoist assembly and a support, fixed pulley is installed on support, and the movable pulley that has suspension hook is installed by steel rope, said support is the jack column of being made up of sleeve and pull bar, one end of steel rope is fixed on the pull bar of jack column, the other end is on the steel rope reel of Jack elevator assembly, said hoist assembly comprises a motor, be connected with the worm drive retarder by coupling sleeve on the output shaft of motor, said cable drum is coaxial with the worm gear of worm drive retarder, in order to realize remote control and manual dual-use function, on the power lead of motor, be parallel with teleswitch receptor and manual switch.After motor is opened in manual control or remote control, drive worm gear,, promptly drive reel and rotate because reel is coaxial with worm gear by worm screw.If use remote control control power, by hand-held remote control switch projector, can rotate by the teleswitch starter motor, and by the rotation of worm gearing drive reel, movable pulley is put into downstairs from roof, after installing goods on the suspension hook, transmit by remote controller again freight lifting is arrived upstairs, finish the working process of starting parcel.

The utility model has the advantages that:

1, support of the present utility model is a jack column, installs at enclosed balcony, and pull bar can stretch out outside the balcony, is not subjected to any restriction, not in the time spent retractable sheath tube, so simple in structure, easy to operate; Owing to adopt worm drive, have the characteristics of reliable in mechanical performance, scantling of structure compactness and transmission self-locking, operate steadily so promote, and support and elevator assembly, comprise that motor, retarder, cable drum etc. separate with support, only connect, improved the complete machine safety by steel rope.

2, according to the service condition difference, the utility model can be selected the different motors of 180W～250W, 750W or 1000W, and lifting weight does not wait to 1000kg applicable to 30kg, 500kg, can satisfy the needs that family and general unit building promote goods.Particularly select the motor of 180～250W, hoisting depth 30～40m is family's essential product a kind of small portable, the inhabitation high-rise building.

3, in addition, the utlity model has two cover lifting forms, both remote-controlled startup (under one-man's situation), can manually boot again (upstairs, all has under people's the situation downstairs, or at remote controller not under at one's side the situation), can satisfy the needs that play heavy articles under the different situations.And when the one-man,, need not come and go upper and lower building by remote manipulation, brought very big convenience to the user.

4, the utility model also is equipped with limit switch on support, when weight rises to setting height, can be out of service voluntarily, and further improved the safety of lifting.
