Abstract
The invention discloses a labor-saving hand wheel. The labor-saving hand wheel comprises a hand wheel body. The hand wheel body is formed by a circular frame and a plurality of supports located at the diameter portions of the circular frame, a hexagonal hole is formed in the center where the multiple supports are connected, and four operating rods are symmetrically arranged on the periphery of the circular frame at equal intervals. By means of the labor-saving hand wheel of the structure, rotating fastening work of a screw can be conveniently and rapidly completed in a labor-saving mode.
Description
Technical field
The invention belongs to field of electrical equipment, be specifically related to a kind of laborsaving handwheel rotated for screw rod.
Background technology
Gantry gate hoists all have bearing pin for the wire rope running block that promotes and all kinds of grasping beam, the weight of weight passes to bearing pin by grasping beam and is delivered to and hangs head and wire rope.The power that pin bearing is subject to is very large, usually thicker.Connect grasping beam to be undertaken wearing pin by screw rod with the bearing pin hanging head, the friction force of screw rod is also larger.
Present mode installs a handwheel in screw rod end, manually rotate handwheel to realize wearing pin, but when bearing pin is a little tight a little, with the hands rotation hand wheel is worn pin and is compared effort, and sweat ought be had on hand, be the phenomenon that can occur to skid at rotation hand wheel, there is the inconvenient and problem of waste of manpower of manual rotation handwheel like this.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned the deficiencies in the prior art, and the laborsaving handwheel of the one provided, and it can solve the large and problem of waste of manpower of handwheel difficulty in rotary course of existing rotary screw.
The object of the present invention is achieved like this:
A kind of laborsaving handwheel, it comprises handwheel, and handwheel is positioned at circular frame to be configured to diametrically by circular frame and Duo Gen, and be provided with hexagonal hole at the center of the handing-over of many supports, described circular frame periphery is arranged with four control lever at equal intervals.
Circular frame is provided with multiple control lever perpendicular to rounded face.
The present invention achieves following technique effect:
When adopting said structure, this device well can complete the rotational fastener work of screw rod;
Have employed and be provided with the structure of control lever perpendicular to rounded face at circular frame periphery and on circular frame, control lever can facilitate holding of engineering staff, the rotation that engineering staff is convenient by control lever, labour-saving completes handwheel thus well complete the rotational fastener work of screw rod;
Have employed control lever and have four, be symmetrically set in the structure on circular frame at equal intervals, multi-person synergy can be made to coordinate rotation hand wheel, improve the handling of handwheel.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of laborsaving handwheel as shown in Fig. 1, it comprises handwheel, handwheel is positioned at circular frame 2 support 1 diametrically by circular frame 2 and Duo Gen and forms, and be provided with hexagonal hole 4 at the center of the handing-over of many supports 1, described circular frame 2 periphery is arranged with four control lever 3 at equal intervals.
Circular frame 2 is provided with multiple control lever 3 perpendicular to rounded face.
When adopting said structure, will treat, in rotary screw end wedging hexagonal hole 4, manually to pull by single or many people the object that control lever 3 reaches rotary screw, the rotational fastener work that energy is convenient, labour-saving completes screw rod.
