Abstract
The utility model belongs to the fixing device technical field, and provides a pulley suspension device of power transmission tower cross-arm angle irons; the pulley suspension device mainly comprises a horizontal support plate; a hook support plate extends from a top surface of a right segment portion of the horizontal support plate; a hang piece horizontally extends from a left side surface of the hook support plate; a left segment portion of the horizontal support plate is provided with a long strip adjusting through hole; a bolt is arranged in the adjusting through hole; an antiskid pad is sleeved between a bolt head and the horizontal support plate; a tail portion of the bolt is provided with a screw nut; a press piece is sleeved between the screw nut and the horizontal support plate; a bottom surface of the horizontal support plate on a right side of the hook support plate is provided with a pulley fixing piece; the pulley suspension device smartly changes bearing mode of the cross-arm angle iron by a lifting tool, single point concentrated load bearing is changed to surface bearing, so bearing area is increased; pulley locking effect is good; the pulley suspension device is light in structure, simple in operation, and convenient to carry and mount.
Description
Technical field
The utility model belongs to fixture technical field, particularly a kind of pulley suspension device of transmission tower cross-arm angle bar.
Background technology
Need on electric power line pole tower, during operation, conventionally coaster directly be hung on cross-arm angle bar and be used with pulley suspension.There is following defect in such occupation mode: first due to the bending structure of cross-arm angle bar, coaster locking device can not normally be agreed with, cause locking to lose efficacy, the potential safety hazard that exists coaster to come off in operation process, coaster hook and the direct dry friction of cross-arm angle bar simultaneously, easily, by the zinc layer abrasion on cross-arm angle bar, damage cross-arm; Coaster is when changing large span use in addition, because the coaster hanging point position single-point centralized load of cross-arm angle bar is stressed, easily cross-arm angle bar is pullled to distortion, after the distortion of cross-arm angle bar, affect the whole force way of itself, damaged cross-arm angle bar, make its normal service life shorten or scrap, more even cause electric power safety accident.Therefore, work about electric power personnel also try to explore new pulley suspension mode, for example: adopt insulation rope sling to do hanging point, but insulation rope sling and cross-arm angle bar contact-making surface are shearing shape, easily cause rope sling to shear wearing and tearing or mill end, have equally certain potential safety hazard.High speed development along with power industry, each cargo handling operation should actively be innovated, think that solving traditional cross-arm angle bar hangs the series of problems such as the coaster occurring in coaster operational method comes off, angle bar distortion, Zinc Scaling, the breakage of insulation rope sling, is necessary to explore a kind of pulley suspension device of transmission tower cross-arm angle bar.
Utility model content
The utility model is that the technical scheme that its technical problem of solution is taked is, design a kind of pulley suspension device of transmission tower cross-arm angle bar, its structure comprises: the horizontal supporting plate of strip, upper surface in right section of part of horizontal supporting plate extends a hook supporting bracket, this hook supporting bracket is perpendicular to described horizontal supporting plate, left-hand face in hook supporting bracket is flatly extended a hanging block, between this hanging block and hook supporting bracket, horizontal supporting plate, surrounds a hook structure; In left section of part of described horizontal supporting plate, offer the adjusting through hole of a strip, in this adjusting through hole, be provided with a bolt, sheathed improved mat between bolt bolt head and horizontal supporting plate, is provided with nut, sheathed briquetting between nut and horizontal supporting plate at the afterbody of bolt; Also the lower surface at the horizontal supporting plate on described hook supporting bracket right side is provided with a coaster fixed block, this fixed block comprises a n shape support consisting of top board, left plate, right plate, top board and the horizontal supporting plate of support are hinged, between left and right side plate, wear a set bolt, set bolt is and is threaded with left and right side plate.
Further, the lower surface of described briquetting offers groove.
During use, hook structure is engaged with the horizontal angle bar outer end of cross-arm angle bar, then adjust bolt position, fastening nut, make briquetting compress the top of the vertical angle bar of cross-arm angle bar, then back out the set bolt on n shape support, coaster hanging point is placed in n shape support, then be selected into set bolt coaster is fixed.The pulley suspension device of this Novel power transmission cross arm of tower angle bar, changed dexterously the stress form of hoisting tool to cross-arm angle bar, by single-point centralized load, stressed to change face into stressed, increase lifting surface area, coaster latch effect is good, and structure is light, simple to operate, the installation that is easy to carry, guarantees to promote load load within the scope of 3T through test, and coefficient of safety is not less than 2.
Accompanying drawing explanation
Below in conjunction with accompanying drawing 1 and embodiment, structure of the present utility model is further described, its structure and advantage will be clearer.
Embodiment
Referring to Fig. 1, a kind of pulley suspension device of transmission tower cross-arm angle bar, its structure comprises: the horizontal supporting plate 1 of strip, upper surface in 1 right section of part of horizontal supporting plate extends a hook supporting bracket 2, this hook supporting bracket 2 is perpendicular to described horizontal supporting plate 1, left-hand face in hook supporting bracket 2 is flatly extended a hanging block 3, between this hanging block 3 and hook supporting bracket 2, horizontal supporting plate 1, surrounds a hook structure; In left section of part of described horizontal supporting plate 1, offer the adjusting through hole 4 of a strip, in this adjusting through hole 4, be provided with a bolt 5, sheathed improved mat 6 between bolt 5 bolt heads and horizontal supporting plate 1, afterbody at bolt 5 is provided with nut 7, sheathed briquetting 8 between nut 7 and horizontal supporting plate 1; Also the lower surface at the horizontal supporting plate 1 on described hook supporting bracket 2 right sides is provided with a coaster fixed block 9, this fixed block 9 comprises a n shape support consisting of top board, left plate, right plate, the top board of support and horizontal supporting plate 1 are hinged, between left and right side plate, wear a set bolt 10, set bolt 10 is and is threaded with left and right side plate.
Further, the lower surface of described briquetting 8 offers groove 11.Object is in order to make this device better fixedly on cross-arm angle bar 12.
