(1) Technical field to which the invention described in the claims belongs;This design is a portable steel wire rope electric hoist that can lift or pull heavy heavy objects from all places in the industrial field. The electric hoist that can generate large power at low speed is manufactured by using a garden structure that can rotate and decelerate the electric motor. In the past, the size of the gardenia has to be large and the number of the gardenia has to be arranged several times and the power of a large force has to be transmitted by one tooth. Therefore, The present invention has a drawback in that it is used in a fixed place or a facility, and therefore, the present invention has been made in consideration of this point, I can use my gardener and planet gardener as a way to do it. In the past, a separate braking device was installed for stopping at a proper position during the operation. However, the portable steel wire rope of this invention The electric hoist is a structure that does not move even if the hoist load is generated due to the structure of the gardener while the motor is stopped and the motor is shut off by using the newly designed garden structure.;(2) Technical challenges to be solved by the design;This design simplifies the structure of the electric hoist, reduces the volume, and makes the portable steel wire rope electric hoist suitable for the purpose of use. It has a separate structure for high rotation deceleration and large power transmission in small volume space. In order to realize a structure that can stop naturally and surely at a desired proper position by using a garden structure without using a braking device, six planetary gratings (8) are applied by applying the principle of a planetary grating, In order to increase the rotation speed reduction ratio in the first stage, the tool (9) and the tool (12) are used to form 69 teeth in two pieces and the tool (12) In order to make the pitch circle the same, the teeth should be formed with a proper amount of potential so that the number of teeth of the pinchers (9) and the pitchers (12) The inner gardeners 9 having 69 teeth are arranged side by side on both sides of the inner garden tool 12 having the teeth of 72 teeth and fixed to the case 10 with bolts. (9), (12), and (12), which are not fixed among the three sets of teeth (9) and (12) The rotational speed of the planetary gears 8 is reduced by 24 to 1 when the pitcher 12 having 72 teeth is rotated by one revolution of the planetary gears 8 and when the planetary gears 8 are stopped, (9) and two-stage planetary gears (9) and one planar gear (12) and planetary gears (8) are connected in a straight line, The principle of reliable braking by the gardener 8 is applied.;(3) The point of solution of design;In order to transmit the power to the gardener, a plurality of teeth are formed on one gardener and the power is transmitted to only one sawtooth. In order to transmit a great power, the gardener and the saw tooth are used in a large size. However, In order to reduce the size of teeth and teeth, it is possible to transmit a large power by devising a planetary gear structure which can transmit power. In rotation deceleration principle, conventionally, The difference between the total number of teeth of the one gardener and the minimum number of teeth of the two gardeners was designed to be the reduction ratio. In the braking structure, the teeth of the garden tool (9) The teeth of the inner garden tool 12 are arranged side by side in a straight line so that the teeth of the planetary garden tool 8 are coupled together and stopped by the planetary garden tool 8 It was.;(4) Important Uses of Design;As for the purpose of this invention, it can be applied to a small volume and high deceleration mechanism in a small volume in a rotary machine structure of a rotating machine. It can be used for industrial facilities, a ceiling crane, a straw crane, a crane for truck mounting, a vinyl house warming-Construction material transporting, warehousing warehousing, warehousing of goods, installation of heavy equipment, lifting of heavy cargo, rescue of car rollover, installation of high-altitude operation facilities, lifting and lowering of industrial elevators, lifting and lowering of general elevators, etc.
