Abstract
The utility model belongs to clamping devices for lifting wire ropes in construction work, and comprises a force-reducing wire rope pulley, a baffle plate, an arc-shaped baffle plate, a wire rope fixing splint, a dowel pin, a connecting plate, a counterweight hanging board, a movable splint, a wire rope, a spring support rod, etc. The single-ply wire rope is wound on the force-reducing wire rope pulley by three and a half circles (with the effective wrap angle of 7 Pi), and is then efficiently clamped via the wire rope splint, thereby solving the problem of the conventional elevator that a two-ply wire rope, clamped in the same rope clamp, bears large radial force and is deformed and damaged due to mutual extrusion, which leads to low safety factor and labor-consuming disassembly and assembly during the operation of the wire rope of the elevator. The utility model protects the wire rope of the elevator in the construction work from damage, and is a clamping device with ideal clamping effect.
Description
Technical field
The utility model belongs to the equipment of building operation gig, particularly a kind of fixing device of building operation hoisting cable.
Background technology
In high-building construction, gig is to be used for realizing people, the requisite main equipment of goods vertical transport, the device of vertical transport adopts monolateral cage usually, match with counterweight, adopt steel rope to be connected by head sheave between counterweight and the cage, when building raise gradually, the steel rope usable length that connects between counterweight and the cage also needed increase thereupon, this just must have one to unclamp steel rope clamping device, the process that clamps again behind the steel rope that lengthens.But existing fixing device is behind the wire rope pulley with steel wire penetrating counterweight wheel seat, again two steel ropes are closed up, by three rope clamps it is clamped, for the gripping power that makes three rope clamps can be enough to bear the axial force of counterweight to steel rope, when clamping, the cylinder faying face of two steel ropes because of local mutual extrusion, produces bigger distortion even damage.When the deformation damage position, when placing active section and the head sheave friction, bear the fitfull stress loading simultaneously, be easy to produce problems such as pine strand, disconnected thigh, make the safety factor reduction of work.
The utility model content
The purpose of this utility model is: provide a kind of usefulness to subtract power wire rope pulley (1) and bear active section, all axial forces also circumferentially reduce gradually, steel rope strap (4) only bears with ambulatory splint (8), power wire rope pulley (1) draws from subtracting, the residue pulling force of steel rope (9), steel rope strap (4) only clamps steel cable (9) with ambulatory splint (8), and make clamping place not produce any distortion, and unclamp, clamp fast, building operation gig simple to operate, steel rope zero damage fixing device.
Technical solution of the present utility model is: a kind of fixing device of building operation hoisting cable, it is formed by subtracting power wire rope pulley (1), baffle plate (2), camber baffle plate (3), steel rope strap (4), pin (5), connecting panel (6), counterweight link plate (7), ambulatory splint (8), steel rope (9) and spring spacer bar (10).It is characterized in that: fixedly subtract power wire rope pulley (1) between two plate washers (2), there is a camber baffle plate (3) baffle plate (2) top, two baffle plates (2) connect connecting panel (6) by pin (5), connecting panel (6) is fixed on the counterweight link plate (7), be connected spring spacer bar (10) between one side of counterweight link plate (7) and the baffle plate (2), opposite side is equipped with two steel rope straps (4), and a circular folder hole less than steel rope (9) diameter is arranged in the middle of steel rope strap (4) and the ambulatory splint (8).
The utility model has the advantages that employing subtracts power wire rope pulley (1) and bears all axial forces of active section, steel rope strap (4) only bears from subtracting the steel rope residue pulling force that power wire rope pulley (1) is drawn, it is inner arc surface that steel rope clamps the position, be easy to realize that single-strand rope effectively clamps and zero damage, when having overcome twin cable and in same rope clamp, clamping, bear the steel rope distortion that big diametral load and mutual extrusion cause and the shortcoming of damage.
Description of drawings
In conjunction with the accompanying drawings the utility model is once described:
Accompanying drawing 1 is the fixing device structural representation of building operation gig steel rope.
Accompanying drawing 2 is the fixing device of building operation hoisting cable, and steel rope twines scheme drawing.
(1) subtracts the power wire rope pulley, (2) baffle plate, (3) camber baffle plate, (4) steel rope strap, (5) pin, (6) connecting panel, (7) counterweight link plate, (8) ambulatory splint, (9) steel rope, (10) spring spacer bar.
The specific embodiment
The utility model is to go up at counterweight link plate (7) to be connected with two baffle plates (2) by connecting panel (6) and pin (5), fixedly subtract power wire rope pulley (1) between the baffle plate (2), the other end captive joint two cover steel rope straps (4) and ambulatory splint (8) of counterweight link plate (7), for preventing from plate washer (2) and subtract power wire rope pulley (1) to tilt to steel rope strap (4), baffle plate (2) one sides link to each other with counterweight link plate (7) by spring spacer bar (10).The usable length of steel rope (9) also will increase when the guide rail bracket height increases, at this moment, allow counterweight fall within base, after steel rope (9) unloads power, unclamp steel rope strap (4), lengthen steel rope (9) to Len req from the steel wire rope support, steel rope strap (4) is clamped again, gig can enter normal operation.Because the steel rope of this device (9), be after subtracting power wire rope pulley (1) and go up twining three circles half (effectively cornerite is 7 π), upwards link to each other with counterweight through head sheave, for increasing cornerite, one camber baffle plate (3) is housed in the top of baffle plate (2), steel rope (9) is subtracting power wire rope pulley (1) surface, the vertical application force that circumferentially distributes that produces, make steel rope (9) and subtract power wire rope pulley (1) surface generation friction force and hinder its slide relative, realize that the steel rope axial force reduces gradually, the axial force of the steel rope (9) of steel rope strap (4) required balance, be 1/20th of active section only, and on the interior faying face of steel rope strap (4) and ambulatory splint (8), there is clevis hole, a garden can realize reliably that single-strand rope effectively clamps, and make steel rope (9) zero damage, when having overcome twin cable and in same rope clamp, having clamped, bear steel rope distortion and damage that big diametral load and mutual extrusion cause, when having improved gig work widely, the safety factor of steel rope, be the building operation gig, the steel rope zero damage clamps optimal fixing device.
Claims (2)
1. the fixing device of a building operation hoisting cable, it is by subtracting power wire rope pulley (1), baffle plate (2), camber baffle plate (3), steel rope strap (4), pin (5), connecting panel (6), counterweight link plate (7), ambulatory splint (8), steel rope (9), and spring spacer bar (10) is formed, it is characterized in that: affixed one subtracts power wire rope pulley (1) between two baffle plates (2), there is a camber baffle plate (3) baffle plate (2) top, two baffle plates (2), connect connecting panel (6) by pin (5), the affixed counterweight link plate of connecting panel (6) (7), be connected with a spring spacer bar (10) between one side of counterweight link plate (7) and the baffle plate (2), opposite side is equipped with two steel rope straps (4).
