Problems solved by technology
[0002] To move goods of about 2 tons within a short radius and a low height range, if a large crane is used, the cost is high and a large working space is required; if a small hydraulic crane is used, the disadvantage is that the lifting height and distance are relatively large. Short and cannot be rotated; if a light single boom driven by a hydraulic or electric winch is used, the disadvantages are: the cost is high, and a fixed and horizontal platform is required, which takes up effective space

Embodiment Construction
[0016] Referring to the accompanying drawings, a hand-operated rotary boom includes: a winch 1, a rod body 2, a two-wheel block 3, a single ear 4, a double pulley support 5 and a wire rope;
[0017] Winch 1 includes: handle 6, bushing 7, bushing, worm 9, first thrust bearing 10, shell cover 11, wedge joint 12, reel 13, shaft 14, housing 15, worm gear 16; worm 9 is located in the housing 15, one end of which extends out of the housing 15 and is fixed with the handle 6. Between the worm 9 and the housing 15, a bushing and a shaft sleeve 7 are installed in sequence. The shaft sleeve 7 and the housing 15 are fixed by bolts, and the bushing and the shaft sleeve 7. Interference fit, the first thrust bearing 10 is set on the worm 9 to reduce the influence of the axial force on the rotation of the worm 9; the shell cover 11 and the shell 15 are fixed to the rod body 2 by bolts, and the shaft 14 is elastically blocked at both ends The ring is limited, and is respectively connected with...

The invention belongs to the technical field of hoisting machinery, and particularly relates to a manual suspender. The hand-rocking revolving suspender comprises a winch, a suspender body, a double sheave pulley, a single lug, a two-pulley support and a steel wire rope. When a person rocks a handle, a worm is driven to rotate, the worm drives a worm wheel, the worm wheel drives a coiling barrel through a shaft, the coiling barrel rotates to drive the steel wire rope to be taken up and paid off, and therefore a hoisted object fixed to the double sheave pulley can be hoisted and put down. When the suspender is rotated, a thrusting bearing reduces influence of friction caused by axial force on rotation, a deep groove ball bearing reduces influence of friction caused by contact with a suspender seat on rotation, the flexibility of the suspender is greatly improved, and therefore horizontal revolving of the hoisted object is realized. The suspender and the suspender seat are separated, an effective space is not occupied, the weight is light, and manual operation and use are allowed. A rolling bearing is used in the contact position of the lower end of the suspender body and the suspender seat, friction of the suspender and the suspender seat is reduced, and revolving of the suspender and the hoisted object is facilitated.
Description
technical field [0001] The invention belongs to the technical field of hoisting machinery, in particular to a manual suspender. Background technique [0002] To move goods of about 2 tons within a short radius and a low height range, if a large crane is used, the cost is high and a large working space is required; if a small hydraulic crane is used, the disadvantage is that the lifting height and distance are relatively large. It is short and cannot be rotated; if a light single boom driven by a hydraulic or electric winch is used, the disadvantages are: the cost is high, and a fixed and horizontal platform is required, occupying an effective space. Contents of the invention [0003] The purpose of the present invention is to provide a hand-operated rotary boom that does not occupy effective space, is suitable for handling goods within a relatively short radius and low height, is light in weight, can be manually operated and used, and has strong lifting capacity. [0004]...
