Abstract
The utility model relates to a universal wire rope power unloading and blemish preventing ball, comprising an upper ball 1 and a lower ball 2, wherein the upper and lower balls both comprise spherical shells 4 with the screw threads being provided on the lower of the spherical shells, shaft bearings 5, screw nuts 7, and rotation shafts 3 which comprise shaft levers 12 and shaft shoulders 14. Shaft levers are plugged in the spherical shells, the shaft shoulders are arranged on the top of the spherical shells, and sealing rings 13 are arranged between the shaft shoulders and the spherical shells of both balls. The shaft levers, screw nuts and elastic collar clamps 10 are respectively arranged on the shaft levers of both balls, and the shaft levers and the screw nuts are fixedly connected by axial positioning screws 11. A stress hole is opened on the shaft shoulder, and the upper ball is spun on the lower ball. The utility model has double ends to prevent blemish, thereby achieving high safe reliability, good hermeticity, simple structure and being convenient to install.
Description
The utility model relates to a kind of steel cable relief knot-preventing ball.The steel cable that is widely used in door machines such as harbour, boats and ships, industrial and mineral, harbour, hanging device unloads the anti-Yi of power and uses.Belong to the cargo handling technical field.
Chinese patent ZL99256223.6 discloses a kind of multi-functional steel cable quick-unreeving anti-twisting ball.It is made up of ball upper casing, ball lower body and stressed structure.Ball upper casing top is provided with the shell hole, shell silk, the inner plug of placing are arranged at the bottom, and steel cable posts on plug after penetrating through the shell hole, passes through the shell hole again.There is following deficiency in this anti-rotation ball:
1, only unloading the active rotary head of Yi (rotating shaft) in an employing of spheroid, is cisco unity malfunction as the spheroid internal bearings because of damage.
Only adopt thread lock between 2, rotating shaft (stressed hook) and mother nut,, throw and fall, collide to be easy to make be threaded and get loose because of the performance characteristic of this product is in irregular vacant state always, produce rotating shaft and mother nut running, safety reliability is poor, and hidden danger is many, and working life is short.A lot of major casualties all produce therefrom.
3, the oily device of not dustproof, the anti-stream in rotating shaft and spherical shell junction, bearing and rotating shaft are worn and torn easily, fragmentation, make that to unload Yi malfunctioning.
4, hard when whole anti-rotation spherical structure complexity, installation fee.
The purpose of this utility model is to provide a kind of can double end anti-Yi, safety reliability good, good airproof performance, simple in structure, omnipotent easily steel cable relief knot-preventing ball is installed.
The purpose of this utility model is achieved in that a kind of omnipotent steel cable relief knot-preventing ball, it is made up of upper sphere and lower sphere two-part, upper sphere and lower body ball include spherical shell, rotating shaft, bearing and nut, rotating shaft comprises the axostylus axostyle and the shaft shoulder, and its axostylus axostyle is plugged in the spherical shell, and the shaft shoulder places the spherical shell top, bearing and nut are housed on the axostylus axostyle successively, have attachment hole on the shaft shoulder, the spherical shell bottom is shaped on screw thread, and upper sphere is spun on the lower sphere.
For improving connection reliability, the utility model revolves at the nut tail end puts flexible collar; Be connected with the axially locating screw between axostylus axostyle and nut; The crosswise fixed bolt will be used between upper sphere and lower sphere.
For improving sealing, the utility model is provided with seal ring in rotating shaft and spherical shell junction.
Compare with existing anti-rotation ball, the utlity model has following advantage:
1, adopts two ends to unload the active rotary head of Yi (rotating shaft), make whole three parts (two ends rotary head, middle spheroid) all be in 360 ° and rotate the Yi state that unloads arbitrarily.Even a certain step bearing is because of life damage, the other end still plays the effect of proper functioning, has no damage to steel cable and by the workpiece that lifted.
2, the fixedly employing Cock screw of rotating shaft and mother nut with set up flexible collar and screw locking structure combining, make that product falls in any throwing, guarantee fixedly not running of mother nut in the impact operations process that safety reliability is good.
3, adopt anti-seepage flow seal ring sealing between rotating shaft and spherical shell, thoroughly eliminated the intrusion of the oil impregnate and the dust of lubricant oil, make bearing be in normal working for a long time, prolonged the working life of product,
4, whole knot-preventing ball is formed by connecting by identical last lower sphere, and is simple in structure, install conveniently, and cost of production is low.
Fig. 1 is a general structure schematic representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As Fig. 1, the utility model is a kind of omnipotent steel cable relief knot-preventing ball, is made up of upper sphere 1 and lower sphere 2 two-part, and upper sphere 1 and lower sphere 2 are formed by spherical shell 4, rotating shaft 3, bearing 5 and nut 7.Rotating shaft 3 is made up of the axostylus axostyle 12 and the shaft shoulder 14.Its axostylus axostyle 12 is plugged in the spherical shell 4, and the shaft shoulder 14 places spherical shell 4 tops, seals with seal ring 13 between shaft shoulder lower end surface and spherical shell upper-end surface.Adorn bearing 5, nut 7 and flexible collar 10 on the axostylus axostyle 12 successively.7 on axostylus axostyle 12 and nut are fixedlyed connected with axially locating screw 11.Open stress hole 15 on the shaft shoulder 14, spherical shell 4 bottoms are shaped on screw thread 19, and upper sphere 1 is spun on the lower sphere 2, connect into a whole knot-preventing ball.Spheroid one side is provided with lubricating cup 6, communicates with the bearing of spheroid inside.2 of upper sphere 1 and lower spheres are fixing with crosswise fixed bolt 9 and retaining spring washer 8.
Steel cable 18 is placed through in the steel cable shackle 16 during installation, and the steel cable shackle is fixed on the stress hole of knot-preventing ball two with bolt 17.
