Abstract
The invention discloses a rope guide for a roller type electric hoist. The rope guide is provided with a rope guide body, wherein two roller seats are fixedly installed on the rope guide, fixed rollers are respectively installed on the roller seats, grooves are formed in the outer circumferential surfaces of the fixed rollers, connecting rods are respectively installed on the sides of the fixed rollers, and the connecting rods are pressed against the grooves in the outer circumferential surfaces of the fixed rollers, which are made of wear resistant plastic and can be removed and replaced. According to the rope guide, the rollers which can be replaced are matched with the double connecting rods, and sliding friction is changed into rolling friction, so that a friction coefficient is greatly reduced, and noise and wear are reduced; the rollers are clamped on the fixed seats, so that the rollers can be conveniently removed and replaced, lubricating grease can be easily applied, and wear conditions can be easily observed; existing single-rod stress is changed into double-rod stress, so that the cross section of each connecting rod is reduced, the whole weight is reduced, and the cost is reduced.
Description
technical field:
The present invention relates to hoist ceiling crane apparatus field, particularly relate to a kind of roller type hoist ceiling crane rope guide.
background technology:
Rope guide is rope winding jib again, is one of accessory of electric block, and its effect makes steel rope fitly be arranged on reel, and to prevent steel rope chaotic, overlap waits and causes electric block to produce mechanical breakdown, even damages electric block.The effect of reel in lifting mechanism, is used for Wound steel rope, transferring power, and rotary motion is become straight-line motion.Mandrel surface cuts out plug helix usually, and its lead angle, generally at 3 °-4 °, increases the area of contact of steel rope, and prevents the mutual friction of adjacent wires rope phase, improves the service life of steel rope.The plug helix cut out due to reel also has conductor rope function, makes steel rope energy proper alignment.But often do not having the synergy of other auxiliary mechanisies, the steel rope be wound on reel can jump out plug helix, steel rope is made to arrange disorderly; Sometimes steel rope enters in reel ends gap and can be extruded distortion: also have steel rope and skip several plug helix; Fitfull arranges, and can make steel rope, reel abrasion deformation: this all will affect the use of reel, steel rope in a word, thus shortens the service life of hoisting crane.Rope guide itself can not rotate, when spool turns, with wire rope roll around, driven by thread groove and move vertically, be at any time wound around steel rope is introduced, drawn the plug helix of reel exactly, steel rope is discharged by the breach of rope guide.During rope guide work, lateral force is very large, and therefore Chang Rongyi causes trisection, is one of the most damageable part on electric block.Rope guide has following advantage (1), avoids the winding of steel rope, ensures that electric block normally works; (2) service life of steel rope, reel, is extended; But existing rope guide is fixed sturcture, rope guide stops is used on the rope guide of steel-wire rope type electric block, is screwed and plays guiding and anti-rotation effect on the connecting rod that rope guide upper groove is stuck in reel outer cover.The defect that existing rope guide exists is: when rope guide works, stops can rub to produce with pull bar and wear and tear and sizable noise, installs inconvenient.Therefore imagination provides a kind of equipment to solve this problem.
summary of the invention:
It is simple that object of the present invention is just to provide a kind of structure, easy for installation, wearing and tearing and the little hoist ceiling crane rope guide of noise.
The technical solution used in the present invention is:
A kind of roller type hoist ceiling crane rope guide: there is rope guide body, rope guide is installed with two roller mount, each roller mount is all provided with and determines roller, determine roller outer circumference surface and be provided with groove, eachly determine roller side and be all provided with pipe link, pipe link leans on the groove determining roller outer circumference surface.
Describedly determine roller and use wear-resistant plastic to make, and detachably to change.
Compared with prior art, beneficial effect of the present invention is:
Present invention uses replaceable roller and coordinate dual connecting rod, changing cliding friction is friction of rolling, greatly reduces friction coefficient, reduces noise and wearing and tearing; Roller is installed on permanent seat, and dismounting and change is convenient, also easily goes up grease and observes wear pattern; By single pole in the past, stressed to change two bar into stressed, reduces the cross section of every root connecting rod, alleviate overall weight and saved cost.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present invention.
detailed description of the invention:
Below in conjunction with accompanying drawing, by embodiment, the present invention is described in further detail:
A kind of roller type hoist ceiling crane rope guide: there is rope guide body 1, rope guide is installed with two roller mount 2, each roller mount 2 is all provided with and determines roller 3, determine roller 3 outer circumference surface and be provided with groove 4, eachly determine roller side and be all provided with pipe link 5, pipe link 5 leans on the groove 4 determining roller outer circumference surface; Determining roller 3 uses wear-resistant plastic to make, and detachably changes.
Above-described embodiment is only preferably embodiment of the present invention, and in addition, the present invention can also have other implementations.It should be noted that, under the prerequisite not departing from the present invention's design, any apparent improvement and modification all should fall within protection scope of the present invention.
Claims (2)
1. a roller type hoist ceiling crane rope guide, it is characterized in that: there is rope guide body, rope guide is installed with two roller mount, each roller mount is all provided with and determines roller, determine roller outer circumference surface and be provided with groove, eachly determine roller side and be all provided with pipe link, pipe link leans on the groove determining roller outer circumference surface.
2. roller type hoist ceiling crane rope guide according to claim 1, is characterized in that: describedly determine roller and use wear-resistant plastic to make, and detachably changes.
