As preferably, described guide pulley is steel bushing.

As preferably, described guide pulley consists of interior copper sheathing, outer steel sleeve and the rubber layer that is arranged between described interior copper sheathing, outer steel sleeve.

As preferably, described interior copper sheathing thickness is 1/3 of described outer steel sleeve thickness, described rubber layer thickness be described outer steel sleeve thickness 1.2-1.5 doubly.

Beneficial effect of the present invention is:

Simple in structure, easy to manufacture, in work, be not easy stuckly, work efficiency is high.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is described further:

Fig. 1 is the structural representation of one embodiment of the invention;

Fig. 2 is the left view of Fig. 1.

The specific embodiment

The following stated is only preferred embodiment of the present invention, not scope of the present invention is limited.

Embodiment, see accompanying drawing 1,2, cable coaster device, comprise support 2 that the supporting plate 1 for load-bearing cable is connected with described supporting plate 1, be fixed on two pairs of side plates 3 on described support 2 and be arranged on two pairs of taper running rollers 4 on described two pairs of side plates 3, described support 2 two ends are provided with bump rubber 8, in present embodiment, supporting plate 1 comprises circular arc guide plate, be arranged on circular arc guide plate for the clamping plate of clamping cables and described clamping plate are fixed on to the bolt on described circular arc guide plate, supporting plate can be 1 layer, also can be two-layer, three layers, determine according to the actual requirements, the base plate of two taper running rollers and I-beam section matches, described taper running roller 4 is provided with side guide ring 5, side guide ring 5 is arranged on the outside of taper running roller, be used for the side of I-beam section guide rail to lead, spacing, it is set directly on taper running roller 4, be convenient to processing, also be convenient to I-beam section to carry out spacing simultaneously, do not need again according to side direction running roller, error and cost have been reduced, reduced stuck probability, between every a pair of described side plate 3, the limit shaft 6 that is positioned at described a pair of taper running roller 4 belows is installed, on described limit shaft 6, guide pulley 7 is installed, can directly be set with, present embodiment is installed by bearing, between guide pulley 7 and a pair of taper running roller, form a space, match with I-beam section base plate, guide pulley 7 is for limiting the bottom surface of I-beam section base plate, guarantee that it is not offset, and then play the stuck effect that prevents, in order to obtain reasonable position-limiting action, the length of described guide pulley 7 is 0.85-0.9 times of distance between described pair of side plates 3, wherein take 0.88 times as good, why adopt whole guide pulley 7, rather than adopt the form of a pair roller, because be to have error (installation error between roller, Mismachining tolerance and wearing and tearing etc.), especially after using after a while, the existence of error can make in spacing to I-beam section, make I-beam section produce deflection, easily stuck.Described guide pulley 7 is arranged on described limit shaft 6 by bearing.

In work, masterpiece on taper running roller 4 is used on side plate 3, make side plate 3 have the trend expanding outwardly, described limit shaft 6 comprises the outer double-screw bolt that is plugged on the smooth shaft in described side plate 3 and is arranged on described smooth shaft two ends, described outer double-screw bolt and nut are spirally connected fixing, side plate 3 is provided with and the smooth shaft of adapter shaft 6 and the through hole of cooperation, side plate 3 can inwardly be slided on adapter shaft 6, this setting, pair of side plates 3 can either be held, prevent that it from expanding outwardly, affect the normal operation of coaster, simultaneously, only to expand outwardly to be locked, and may be when being impacted, inwardly carry out small expansion, reduce stuck probability.

Described guide pulley 7 can adopt carbon steel cover or stainless steel sleeve, and surface heat is processed, and forms thermal treatment layer, has certain hardness.

Further, described guide pulley 7 consists of interior copper sheathing, outer steel sleeve and the rubber layer that is arranged between described interior copper sheathing, outer steel sleeve, such structure, make guide pulley there is enough elasticity and rigidity, at bearing, break down not revolvable time, between interior copper sheathing and limit shaft 6, start rotation, the setting of interior copper sheathing, also has certain lubricating effect, make rotation more smooth and easy, further, described interior copper sheathing thickness is 1/3 of described outer steel sleeve thickness, and described rubber layer thickness is 1.2-1.5 times of described outer steel sleeve thickness.

More than explanation is only explanation of the invention, make those of ordinary skills' can completely implement this programme, but be not limitation of the present invention, those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this specification sheets, and these are all not creative modifications.But as long as within the scope of claim of the present invention, be all subject to the protection of patent law.
