Abstract
The invention discloses a pulley block for a steel wire dragger. The pulley block comprises a base, a first pulley, a second pulley and a third pulley are arranged on the base side by side, a damping device is arranged between the first pulley and the second pulley and comprises an outer shell, and the two ends of the outer shell are provided with a first damping head and a second damping head respectively in a stretchable mode. The two ends of the outer shell are provided with a first groove and a second groove respectively. The damping device is arranged between the pulleys of the pulley block, harmful vibration can be absorbed when a steel wire looses, and sliding and dropping between the steel wire and the pulleys are accordingly avoided.
Description
Technical field
The present invention relates to a kind of sheave block, or rather, is a kind of sheave block for steel wire traction machine.
Background technique
Pulley is that a periphery has groove, the steamboat that can sway.By a plurality of, can rotate fluted disk and stride across the simple and mechanical sheave block that is called that can rotate around central shaft that the flexible cable (rope, adhesive tape, cable wire, chain etc.) of disk forms around central shaft.Sheave block is widely used in current industrial production, just has the use of pair sheave block in steel wire traction machine.
In present industrial production, the sheave block of steel wire traction machine is carrying the changeable active force of wire rope and is using frequently, after wire rope relaxes gradually, is out of shape, will in use there are the vibrations that are harmful to, thereby cause wire rope from sheave block, to come off continually, harm staff's personal safety, affects industrial progress and efficiency.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby provides a kind of sheave block with damping device for steel wire traction machine.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of sheave block for steel wire traction machine, comprise a base, one first pulley, one second pulley and one the 3rd pulley are set abreast on described base, between the first described pulley and the second described pulley, a damping device is set, described damping device comprises a shell, and the two ends of described shell respectively telescopically arrange one first damping head and one second damping head.
As preferred embodiment of the present invention, the two ends of described shell arrange respectively one first groove and one second groove.
As preferred embodiment of the present invention, the first described damping head and the second damping head are that high elasticity butyl renewable rubber is made.
Because sheave block of the present invention is provided with damping device between pulley, when steel wire is lax, can absorb harmful vibrations, thereby avoid skidding and coming off between steel wire and pulley.
accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides and a kind ofly can effectively reduce the sheave block shaking between drivign belt and pulley.
As shown in Figure 1 and Figure 2, a kind of sheave block 1 for steel wire traction machine, comprise a base 2, one first pulley 31, one second pulley 32 and one the 3rd pulley 33 are set abreast on described base 2, between the first described pulley 31 and the second described pulley 32, a damping device 4 is set, described damping device 4 comprises a shell 43, and the two ends of described shell 43 respectively telescopically arrange one first damping, 41 and 1 second damping 42.
As shown in Fig. 3, Fig. 4, Fig. 5, the two ends of described shell 43 arrange respectively one first groove 431 and one second groove 432.
The first damping of this sheave block the 41 and second damping 42 is made for high elasticity butyl renewable rubber.
This sheave block is provided with damping device between pulley, can absorb harmful vibrations, thereby avoided skidding and coming off between steel wire and pulley when steel wire is lax.
Below only with a mode of execution, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more function module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
