Description
Technical field
The present invention relates to the suspender technology, particularly relate to a kind of technology of internal expansion type self-locking sling.
Background technology
In the motor manufacturing process; Often need manpower to move stator core, the stator core of motor all be drum shape and also deal heavier, needing both hands to embrace when manpower moves could carry; This mode of transport exists very inconvenient; Bearer's labour intensity is big, and stator core drops easily, has the low defective of safety.
Summary of the invention
To the defective that exists in the above-mentioned prior art, technical matters to be solved by this invention provides a kind of carrying labour intensity that can alleviate band circular inner hole object, improves the internal expansion type self-locking sling of carrying safety.
In order to solve the problems of the technologies described above, a kind of internal expansion type self-locking sling provided by the present invention is characterized in that: comprise hoisting axis, contact block, linkage rod group;
Said hoisting axis is a d-axis, and its top is fixed with suspension ring, the coaxial ring-type slide block that is arranged with an activity of its axle body;
Said contact block has three, lays around the axis shaft symmetry of hoisting axis;
Said linkage rod group has three groups, the corresponding contact block of each linkage rod group, and each linkage rod group is made up of many straight type connecting rods, and a connecting rod in each linkage rod group is a long connecting rod, and several connecting rods are short connecting rod in addition, and the length of said long connecting rod is greater than the length of short connecting rod;
One end of every long connecting rod and the ring-type slide block on the hoisting axis articulate, and the other end articulates with the top of corresponding contact block, and an end of every short connecting rod and hoisting axis bottom articulate and the articulated section is lower than the ring-type slide block, and the other end articulates with the bottom of corresponding contact block;
The pivot at each connecting rod two ends is all perpendicular to the axis of hoisting axis, and the pivot at each the connecting rod two ends on the same group is parallel to each other, and the axis of each short connecting rod on the same group is parallel to each other;
Every contact block all is fixed with a rubber pad on the side of hoisting axis dorsad.
Internal expansion type self-locking sling provided by the invention; When hanging belt circular inner hole object, adopt four connecting rod theory of machines to produce inner expanding force; Each contact block by gravity is tightly propped up by the hole wall of lifting object endoporus, and lifting suspension ring through one hand can sling object, and the labour intensity of this mode of transport will take the mode of carrying far below both hands in one's arms; And object also is difficult in handling process, dropping, and can improve the carrying safety.
Description of drawings
Fig. 1 is the birds-eye view of the internal expansion type self-locking sling of the embodiment of the invention;
Fig. 2 is the front view of the internal expansion type self-locking sling of the embodiment of the invention when launching;
Fig. 3 is the front view of the internal expansion type self-locking sling of the embodiment of the invention when drawing in.
The specific embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
Like Fig. 1-shown in Figure 3, a kind of internal expansion type self-locking sling that the embodiment of the invention provided is characterized in that: comprise hoisting axis 1, contact block 4, linkage rod group;
Said hoisting axis 1 is a d-axis, and its top is fixed with suspension ring 2, the coaxial ring-type slide block 3 that is arranged with an activity of its axle body;
Said contact block 4 has three, lays around the axis shaft symmetry of hoisting axis 1;
Said linkage rod group has three groups; The corresponding contact block 4 of each linkage rod group, each linkage rod group is made up of many straight type connecting rods, and a connecting rod in each linkage rod group is a long connecting rod 6; Several connecting rods are short connecting rod 7 in addition, and the length of said long connecting rod 6 is greater than the length of short connecting rod 7;
One end of every long connecting rod 6 and the ring-type slide block on the hoisting axis 13 articulate; The other end articulates with the top of corresponding contact block 4; One end of every short connecting rod 7 and hoisting axis 1 bottom articulate and the articulated section is lower than ring-type slide block 3, and the other end articulates with the bottom of corresponding contact block 4;
The pivot at each connecting rod two ends is all perpendicular to the axis of hoisting axis 1, and the pivot at each the connecting rod two ends on the same group is parallel to each other, and the axis of each short connecting rod 7 on the same group is parallel to each other;
Every contact block 4 all is fixed with a rubber pad 5 on the side of hoisting axis 1 dorsad.
The embodiment of the invention is applicable to the object of hanging belt circular inner hole, and its method of application is following:
The embodiment of the invention is handled the deployed condition (see figure 2) under normal condition; This moment, operating personal was with the suspension ring that pull the hoisting axis top; Catching on ring-type slide block and the application of force with finger more upwards slides the ring-type slide block; Under the drive of ring-type slide block, the angle between the long connecting rod in each linkage rod group and each short connecting rod increases, and makes oblique upwards the moving towards hoisting axis of each contact block closely collapse to the rounding state (see figure 3);
Each contact block towards hoisting axis move closely collapse to rounding state after, the embodiment of the invention stretched into waits to lift in the circular inner hole of object, unclamp the finger that catches on the ring-type slide block then; This moment by gravity, the ring-type slide block is to lower slider, and long connecting rod and the angle between each short connecting rod in each linkage rod group are reduced; Each contact block strutted move apart hoisting axis; Rubber pad on each contact block touches the circular inner hole hole wall of waiting to lift object, and hold on the suspension ring and carry this moment, at this moment by gravity; The inner expanding force that acts on each contact block increases; On inner expanding force effect object to be lifted can be with suspension ring, carry and being sling, the rubber pad on each contact block can increase friction force, gives reliable internal expanding.
