Abstract
The utility model discloses an unwrapping wire pulley belongs to the mechanical equipment field, including couple (1), outer frame body (3) and aluminium wheel (4), couple (1) is connected with outer frame body (3), outer frame body (3) are connected with jump ring seat (2), jump ring seat (2) are connected with and prevent jumping block tongue (8), outer frame body (3) left side is connected with stopping nut (5), the right side is connected with stud shaft (7), and its inside bearing effect of playing through stud shaft (7) is connected with aluminium wheel (4), through installing one stud shaft (7) at aluminium wheel (4) intermediate position, play the effect of bearing, it is nimble to make the pulley rotate, no jamming, and pass through jump ring seat (2), prevent jumping block tongue (8) and carry out the optimal design, and all sharp keen outstanding angles smoothness of all polishing, the wearing and tearing of anti -bouncing device to the clue have been prevented effectively.
Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly relates to a kind of pulley block.
Background technology
Identical tension unwrapping wire is the critical process of high-speed electric railway contact network construction, and the quality of its construction quality directly has influence on the overall operation effect of contact system.Pulley block is one of instrument required in identical tension unwrapping wire process, and along with greatly developing of high-speed electric railway construction, more and more higher to the requirement of construction quality, old-fashioned pulley block can not adapt to the needs of identical tension unwrapping wire.Because thread tension force during work is very little, clamping stagnation is less likely to occur, and old-fashioned pulley does not all install bearing substantially, and extensively adopts the pulley block of open type.Because the pulley of remaining silent of old-fashioned design, its anti-bouncing device, the main sheet iron that adopts bends, clip spring seat and the outer frame body of fixing spring are welded, and design unreasonable, processing difficulties, outward appearance and pulley integral inharmonious, use inconvenience, in actual unwrapping wire process also exist wearing and tearing clue phenomenon.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of pulley block.
To achieve these goals, the utility model adopts a kind of pulley block, comprise hook, outer frame body and aluminium to take turns, described hook is connected with outer frame body, described outer frame body is connected with clip spring seat, and described clip spring seat is connected with anti-jump block tongue, is connected with anti-return nut on the left of described outer frame body, right side is connected with bolt shaft, and its inside is connected with aluminium wheel by the bearing effect that bolt shaft plays.
The basis of such scheme is improved, bottom described outer frame body, is connected with earrings.
The basis of such scheme is improved, below described anti-jump block tongue, makes 45 degree of inclined-planes.
The basis of such scheme is improved, and described outer frame body adopts cast-steel integral cast form, has done thicken process 4 corners.
The basis of such scheme is improved, and described aluminium is taken turns inside and outside edge and is all adopted designed arc-shaped appearance, and the inside and outside seamed edge of described outer frame body all carries out smooth treatment.
The beneficial effect that the utility model compared with prior art has is: by installing a bolt shaft at aluminium wheel midway location, play the effect of bearing, make pulley rotation flexibly, without clamping stagnation, be arranged on midway location, one is in order to bearing is symmetrical, balanced load during work; Two is be convenient to machine up, improves working accuracy and work efficiency, takes turns can not be moved vertically when rotating to make aluminium, utilizes bolt shaft to withstand from both sides by aluminium wheel, tightens outside outer frame body with anti-return nut.Meanwhile, by the design optimization to clip spring seat, anti-jump block tongue, and all sharp keen outstanding angles are all polished smooth, effectively prevent the wearing and tearing of anti-bouncing device to clue.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of anti-jump block tongue.
In figure: 1-links up with, 2-clip spring seat, 3-outer frame body, 4-aluminium is taken turns, 5-anti-return nut, 6-earrings, 7-bolt shaft, the anti-jump block tongue of 8-.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
As shown in Figures 1 and 2, a kind of pulley block, comprise hook 1, outer frame body 3 takes turns 4 with aluminium, described hook 1 is connected with outer frame body 3, described outer frame body 3 is connected with clip spring seat 2, and described clip spring seat 2 is connected with anti-jump block tongue 8, is connected with anti-return nut 5 on the left of described outer frame body 3, right side is connected with bolt shaft 7, and its inside is connected with aluminium wheel 4 by the bearing effect that bolt shaft 7 plays.
Above-described embodiment improves further, bottom described outer frame body 3, is connected with earrings 6.
Above-described embodiment improves further, below described anti-jump block tongue 8, makes 45 degree of inclined-planes.
Above-described embodiment improves further, and described outer frame body 3 adopts cast-steel integral cast form, has done thicken process 4 corners.
Above-described embodiment improves further, and described aluminium is taken turns 4 inside and outside edge and is all adopted designed arc-shaped appearance, and the inside and outside seamed edge of described outer frame body 3 all carries out smooth treatment.
Based on above-mentioned, by taking turns 4 midways location at aluminium, a bolt shaft 7 be installed, play the effect of bearing, make pulley rotation flexibly, without clamping stagnation.Be arranged on midway location, one is in order to bearing is symmetrical, balanced load during work; Two is be convenient to machine up, improves working accuracy and work efficiency.Taking turns 4 to make aluminium can not be moved vertically when rotating, utilizing bolt shaft 7 to withstand from both sides by aluminium wheel 4, tightening with anti-return nut 5 outside outer frame body 3.Meanwhile, by the design optimization to clip spring seat 2, anti-jump block tongue 8, and all sharp keen outstanding angles are all polished smooth, effectively prevent the wearing and tearing of anti-bouncing device to clue.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
