Description

Adhere to anti-fall lifting false work

Technical field

The utility model relates to the construction work lifting false work, is specially a kind of anti-fall lifting false work that adheres to.

Background technology

Lifting false work is the auxiliary equipment that must use in the high-building construction, be mainly used in the construction of building and the decoration of outer body of wall, the structure of lifting false work mainly comprises main frame, lifting safety dropping prevent mechanism and be fixed on the overarm of wall outer side and be fixed on main frame near vertical i iron of body of wall one side, the upper and lower end face of i iron is parallel with pairing surface of wall, the overarm outside is fixed with two guide wheels that are positioned at i iron front and back groove, i iron is done relative moving up and down with guide wheel along the I-shaped steel tank, thereby realize that lifting false work moves up and down under the effect of jacking system, but there is following hidden danger to some extent in the lifting false work of these types; The one, adhering between lifting false work and the body of wall generally be by wire rope with main frame and overarm be tied together realize fixing, because overarm is vertical uniform being fixed on the body of wall outer wall, the lifting false work of lifting is equidistantly realized fixing or is satisfied equidistant lifting lifting false work and realize fixing requirement by changing length of steel wire rope when adhering to, and this adhering mode operation is more loaded down with trivial details and can not realize that lifting false work can both realize the requirement of fixing with the overarm on the body of wall at arbitrary height; The 2nd, the transmission system complexity of existing lifting safety dropping prevent mechanism; often have misoperation; especially lifting false work decline process has the frequency of misoperation appearance higher; it is not smooth to be generally locking back release recovery process; sometimes with driving member the mechanical interference phenomenon appears; cause lifting safety dropping prevent mechanism operation precision misalignment, the reliability of influence protection.

Summary of the invention

The utility model causes the problem of the loaded down with trivial details and anti-fall poor reliability of attach operation for the attachment mechanism, the lifting safety dropping prevent mechanism that solve existing lifting false work are unreasonable, provide adhering to of a kind of stable performance anti-fall lifting false work.

The utility model is to adopt following technical scheme to realize: adhere to anti-fall lifting false work, comprise main frame, lifting safety dropping prevent mechanism, hang oneself from a beam and be fixed on the vertical i iron of main frame near body of wall one side, the overarm outside is fixed with two guide wheels that are positioned at i iron front and back groove, have locating hole on the waist of i iron, each guide wheel top all is placed with the attachment that is positioned at the I-shaped steel tank, have on attachment and the face that the i iron waist contacts with locating hole by the fixing installing hole of bearing pin is installed, be provided with supporting pad between the bottom surface of attachment and the guide wheel.Lifting safety dropping prevent mechanism described in the utility model is a prior art, is that those skilled in the art realize easily, has the various deformation structure.During construction, in the time need moving up and down to the position of adhering to anti-fall lifting false work, move up and down by the control of the elevating mechanism on it i iron, thereby drive is adhered to anti-fall lifting false work and is moved up and down, when adhering to anti-fall lifting false work and move to desired location, attachment is placed in the I-shaped steel tank of guide wheel top, by bearing pin is installed attachment and i iron are fixed then, between attachment and guide wheel, supporting pad is installed then, stressed even, realized the fixing of overarm and attachment on the body of wall, thereby overcome the problem of existing lifting false work complex operation, simultaneously owing to have some locating holes on the waist of i iron, can by in locating hole arbitrarily fixedly attachment realize that the arbitrary height of lifting false work fixes.

The lifting safety dropping prevent mechanism comprises the anti-faller that vertically is fixed on the overarm below, the lower end of anti-faller passes and is fixed on the anti-fall support of main frame near body of wall one side, anti-fall support top has mounting hole and be connected with the hanger that electric block is housed by fixed pin shaft in mounting hole, fixed pin shaft is provided with its left end and is supported on drive rod on the fixed pin shaft, the middle part of drive rod has and is installed with the short pin shaft that is fixed on the anti-fall support in mounting hole and the mounting hole, the right-hand member of drive rod is hinged with connecting rod, the other end of connecting rod is hinged on the profile place of cam, hinged between the place, axle center of cam and the locating hole on the i iron by connecting axle, be fixed with extension spring on the drive rod between fixed pin shaft and the drive rod middle part mounting hole, the extension spring other end and anti-fall support bottom are fixed, and the anti-fall support in anti-faller left side is provided with regular jaw.When adhering to anti-fall lifting false work lifting, the electric block that at first starts on the hanger carries out pretension, the left end of drive rod is that the center of circle clockwise rotates with the pin joint of its right-hand member, the stressed right-hand member with drive rod of extension spring is drop-down in the rotation process, it is that the center of circle rotates counterclockwise with cam with its axle center that connecting rod is subjected to downward power, the outline diameter of cam reduces gradually, at this moment adhering to anti-fall lifting false work and anti-faller breaks away from, can satisfy attached lift scaffold moves under the effect of lifting safety dropping prevent mechanism, in the work progress, when adhering to anti-fall scaffold and come off suddenly, the pretension state of hanger and anti-fall support disappears, the extension spring of tensioner is drop-down with the drive rod left end, the right-hand member of drive rod is that the center of circle moves upward with drive rod middle part short pin shaft, thereby with upwards pulling of connecting rod, cam is that the center of circle is done and clockwise rotated with its axle center, the outline diameter of cam increases gradually, because the lower end of anti-faller is a free state, at this moment the regular jaw on cam and the anti-fall support is tight with anti-fall bar cramp, thereby realize adhering to anti-fall lifting false work and the fixing purpose of anti-faller, overcome the problem of the anti-fall poor reliability of traditional lifting false work.

I iron is to be welded by its waist by two channel-section steels, helps improving the longitudinal rigidity of i iron.

Described in the utility modelly adhere to anti-fall lifting false work and improve by its attachment mechanism and lifting safety dropping prevent mechanism have been done effectively, the improvement of attachment mechanism has not only reduced labour intensity, it is convenient simple to operate, and can realize the fixing of lifting false work at arbitrary height when adhering to; The improvement of lifting safety dropping prevent mechanism has avoided having the appearance of misoperation, only just can start lock out action when the power suspension hook loses efficacy, and that the overall improvement structure has is simple in structure, cost is low and the advantage of handled easily.
