Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

The first embodiment,

As shown in fig. 1, a novel lifting appliance, including a vertical jib 2, the top fixedly connected with rings 1 of jib 2, three horizontal bracket 7 of fixedly connected with on the below circumference of jib 2, and three horizontal bracket 7 is around 2 axis evenly distributed of jib, set up a rectangular hole 3 that link up on the thickness direction of horizontal bracket 7, set up a plurality of equidistant through-holes 4 on the horizontal direction of horizontal bracket 7, install round pin axle 5 on two through-holes 4 that correspond, 6 covers of lifting hook are established at round pin axle 5, and lifting hook 6 is located the inside position of rectangular hole 3, detachable installs spacing axle 8 in two through-holes 4 adjacent with round pin axle 5.

Specifically when using, this hoist is used for the hoist and mount of the spare part that fig. 3 shows, incline three lifting hook 6's lower extreme towards the direction that is close to rings 1 axis, make three lifting hook 6 get into the hole position of spare part completely, after three lifting hook 6 gets into the spare part is inside, the effort of exerting on lifting hook 6 is eliminated, lifting hook 6 is free state under self action of gravity, upwards promote jib 2, three lifting hook 6's lower extreme can block and establish inside the spare part, in order to prevent that in-process lifting hook 6 at the hoist and mount from producing and coming off, can install spacing axle 8 in the through-hole 4 that is close to round pin axle 5 one side, the realization is spacing to lifting hook 6, lifting hook 6 of hoist is connected on rings 1, can promote the spare part through promoting this hoist, accomplish the hoist and mount operation.

Example II,

As shown in fig. 2, a novel lifting appliance, including a vertical jib 2, the top fixedly connected with rings 1 of jib 2, 2 lower extreme position welding of jib have a mounting disc 12, the central axis of mounting disc 12 and the central axis of jib 2 coincide each other, the upper surface position of mounting disc 12 is equipped with the nut 10 of six vertical settings, per two nuts 10 are a set of and three nut 10 of group around 2 central evenly distributed of jib, two nut 10 central lines in each set coincide mutually, install round pin axle 11 in two nut 10 central holes in each set, hoist and mount piece 9 is installed at the middle part position of round pin axle 11.

When the lifting appliance is used for lifting parts, the parts to be lifted are shown in fig. 4, the parts are conical, the diameter of the mounting disc 12 is smaller than that of a round hole in the top of the parts, the mounting disc 12 is placed into the round hole during working, the lifting blocks 9 are in a vertical state in the placing process, after the mounting disc 12 is placed into the round hole, a worker rotates the lifting blocks 9 to be in a horizontal state, at the moment, the vertical distance between the outermost ends of the three lifting blocks 9 and the axis of the suspender 2 is larger than the radius of the round hole in the top of the parts, the lifting appliance is lifted by the crane through the rope connected to the lifting ring 1, the parts can be lifted to a specified position through the three lifting blocks 9, after the lifting is finished, the acting force exerted on the lifting appliance is eliminated, the worker rotates the lifting blocks 9 to be in a vertical state again, the mounting disc 12 can be taken out, the lifting appliance is convenient, And (4) reliability.
