Abstract
The invention relates to a lifting device, in particular to a single-phase miniature special electric hoist, comprising a shell 1, a reel 2, a speed reducer 3, a motor 4 driving the reel to rotate, a steel wire rope hook 5 wound on the reel, a limit mechanism 6 and a control component 7. The rated single hooking weight of the electric hoist is 50 Kg; a reel wound by a plurality of layers of steel wire ropes is adopted as the reel 2; a secondary cylindrical external gear transmission speed reducer is adopted as the speed reducer 3; a single-phase capacitance-operating bypassed magnetic braking type asynchronous motor is adopted as the motor 4; and the reel 2, the speed reducer 3 and the motor 4 are orderly connected and are arranged inside the shell 1. The invention has the advantages that as the outer diameter of a smaller stator core is selected, the electric hoist greatly diminishes the external dimension, saves raw materials, reduces manufacturing cost, reduces motor power consumption, provides an energy-saving consumption reducing product, fills a gap in market, satisfies the users with the single hooking weight of about 50 Kg, and has broad market prospects.
Description
Technical field
The present invention relates to a kind of lifting weight-lifting equipment, particularly a kind of single-phase small and special electric gourd
Background technology
Electric block is a kind of general weight-lifting equipment that uses, especially single-phase electric gourd is specially adapted to the important tool that factory floor, domestic automobile room, warehouse etc. lift by crane object and article, it also is the visual plant of service industries such as restaurant, shop, repairing and carrying, commercial production conveyor line, because of adopting single phase poaer supply, use very extensive.But the electric block that occurred on the market and on the data, its specified weight that singly hooks is all more than 100Kg, the frame diameter of asynchronous dynamo is all more than 90mm, external form is big, the raw MAT'L loss is big, manufacturing cost is high, Heavy Weight, install and use inconvenience, and power consumption is high, in energy shortage and the prices of raw and semifnished materials high today, existing product has not been suitable for and has singly hooked the user of weight about 50Kg.
Summary of the invention
The invention provides that a kind of external form is little, compact conformation, raw MAT'L loss are little, low cost of manufacture, in light weight, easy to install, a kind of products that save energy and resources single-phase small and special electric gourd that power consumption is low.
For achieving the above object, the present invention adopts following technical scheme: a kind of single-phase small and special electric gourd, include housing 1, reel 2, retarder 3, drive reel motor rotating 4, be wound in the steel wire rope hook 5 on the reel 2, stop gear 6 and operating element 7, the specified weight that singly hooks of described electric block is 50Kg, the reel that reel 2 adopts the multilayer steel rope to twine, retarder 3 adopts secondary cylinder external gear gearing speed-reducer, motor 4 adopts single-phase capacitor running to be close to magnetic brake formula asynchronous dynamo, reel 2, retarder 3, motor 4 threes connect in turn and place housing 1 inboard.
The present invention further is set to: the frame diameter that described single-phase capacitor running is close to magnetic brake formula asynchronous dynamo is 71mm, and wirerope diameter is 2.5mm, and drum diameter is 30mm.
The invention has the beneficial effects as follows: owing to selected the 71mm littler for use than the frame diameter 90mm of the minimum of using in the existing product, dwindled oad greatly, saved raw MAT'L, reduced manufacturing cost, reduce the motor consumption of current, a kind of products that save energy and resources are provided, filled up the market vacancy, satisfied singly hooking the user of weight about 50Kg, had vast market prospect.
The invention will be further described below in conjunction with accompanying drawing:
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
The specific embodiment
As shown in Figure 1, a kind of single-phase small and special electric gourd, include housing 1, reel 2, retarder 3, drive reel motor rotating 4, be wound in the steel wire rope hook 5 on the reel 2, stop gear 6 and operating element 7, described reel 2, retarder 3, motor 4 threes connect in turn and place housing 1 inboard, the reel that reel 2 adopts the multilayer steel rope to twine, be provided with like this and be beneficial to the user who under the situation that does not change reel 2 oads, satisfies different hoisting depths, enlarge market demand, retarder 3 adopts secondary cylinder external gear gearing speed-reducer, because external gear is processed easily, help reducing manufacturing cost and production in enormous quantities, motor 4 adopts single-phase capacitor running to be close to magnetic brake formula asynchronous dynamo, this kind motor is in braking mode under cold situation, setting motor braking function when electric block has a power failure suddenly in the course of the work or cuts off the power supply can work immediately like this, improved the operating safety factor of electric block greatly, and retarder 3 is set has not so just required braking function, simplify the structure, the present invention also is provided with stop gear 6, stop gear 6 works when electric block runs to end position, has improved the safety of operation coefficient of electric block.
Its principle of work is: after motor 4 energized, when operation operating element 7, motor 4 operations, its braking function lost efficacy, and drove reel 2 by retarder 3, made the steel wire rope hook 5 that is wound on the reel 2 carry object and rose or descend, stop gear 6 works when object rises or drops to end position, motor 4 is out of service, and its braking function works immediately, and object stops to rise or descending.
