Abstract
The utility model relates to a rainproof device of a crane. The rainproof device comprises a large disc and a small disc which are arranged on the top surface of a machine room of the crane, wherein the large disc and the small disc are respectively provided with rotating shafts; the rotating shaft of the large disc is connected with the top surface of the machine room; the small disc is arranged at one side of the large disc; and the small disc is connected with the large disc through the rotating shaft of the small disc. The disc type rainproof device has better rain sheltering effect, automatically adapts to the left-right movement and front-back deflection of steel wires from the machine room through the relative rotation of the large disc and the small disc and is also convenient to operate when a nylon sleeve is replaced.
Description
Technical field
The utility model relates to weight-lifting equipment, refers in particular to a kind of rain insensitive device of hoisting crane.
Background technology
The steel rope outlet at the machine room top of single-cantilever-crane gantry crane arranges rain insensitive device, traditional rain insensitive device adopts two blocks of rubber plates to clamp steel rope, reach rainproof purpose, when steel rope and the machine room top angle 30 degree left and right sides, rubber plate can play good rainproof effect, when steel rope and horizontal plane angle were larger, rainproof effect was relatively poor, and the easy mistake of rainwater enters in the machine room.
The utility model content
The purpose of this utility model is to provide the rain insensitive device of single-cantilever-crane gantry crane of the beat of a kind of movement that can automatically adapt to the steel rope left and right directions and fore-and-aft direction.
For achieving the above object, the utility model adopts following technical scheme:
A kind of rain insensitive device of hoisting crane, comprise big disk and roundel on the machine room end face that places hoisting crane, described big disk and described roundel are provided with rotating shaft respectively, the rotating shaft of described big disk is connected with described machine room end face, one side of described big disk is provided with described roundel, and described roundel is connected with described big disk by the rotating shaft of described roundel.
Further, the position of the rotating shaft of described big disk is corresponding with the center of gravity of described big disk.
Further, the position of the rotating shaft of described roundel is corresponding with the center of gravity of described roundel.
Further, in order to guarantee whole center of gravity at the center of described big disk, an end of big disk is provided with counterweight, and described counterweight places an end relative with described roundel.
Further, described roundel is provided with steel rope, and the angle of this steel rope and described machine room end face is 65-85 °.
Further, the nylon jacket of described steel rope is split type structure.
The utility model adopts the disc type rain insensitive device, and rain-proof effect is better, by relatively rotating of big disk and roundel, automatically adapts to from the movement of machine room steel rope left and right directions out and the beat of fore-and-aft direction, and is also easy to operate when changing nylon jacket.
Description of drawings
Accompanying drawing 1 is front view of the present utility model;
Accompanying drawing 2 is birds-eye view of the present utility model;
Accompanying drawing 3 is machine room end face of the present utility model and construction of wire rope schematic diagram.
The specific embodiment
Referring now to accompanying drawing, further describe the utility model.
With shown in the accompanying drawing 2, a kind of rain insensitive device of hoisting crane comprises big disk 2 and roundel 3 on the machine room end face 1 that places hoisting crane such as accompanying drawing 1, and big disk 2 is provided with the first rotating shaft 21 accordingly, and wherein, the position of the first rotating shaft 21 is corresponding with the center of gravity of big disk 2; It is corresponding with the center of gravity of roundel 3 that roundel 3 correspondences are provided with the position of the second rotating shaft 31, the second rotating shafts 31, and big disk 2 all is positioned at rotating shaft place with the center of gravity of roundel 3, when big disk 2 is with roundel 3 rotation like this, do not need to overcome the skew generation eccentric moment of center of gravity.
The first rotating shaft 21 is connected with machine room end face 1, one side of big disk 2 is provided with roundel 3, roundel 3 is connected with big disk 2 by the second rotating shaft 31, in addition, in order to guarantee that whole center of gravity is at the center of big disk 2, one end of big disk 2 is provided with counterweight 22, and counterweight 22 places an end relative with roundel 3.
With reference to accompanying drawing 3, roundel 3 is provided with steel rope, the angle of this steel rope and machine room end face 1 is 65-85 °, by the rotation of big disk 2 with roundel 3, steel rope on the roundel 3 also automatically adapts to sway and the front and back of slave roof face steel rope out and slightly moves, and the nylon jacket of the steel rope on the roundel 3 is split type structure, and is at change steel rope more and when changing nylon jacket, easy to operate like this.
Above-described the utility model embodiment does not consist of the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
