Abstract
The invention discloses a windtight rail clamping device of a roof surface lazy arm for a high-rise building. The windtight rail clamping device consists of a connecting frame and two rail clamping plates, wherein the two rail clamping plates are suspended at two sides of the connecting frame, and grooves which are formed in the lower parts of the rail clamping plates are adapt to the shape of the upper part of a rail. The rail clamping device of the lazy arm is arranged on the rail, a lazy arm frame can be fixedly arranged on the rail, and the wind resistance of the lazy arm under the non-operating state of a high-rise work roof surface lazy arm can be realized, so that the safety of a high-rise work roof surface lazy arm tower crane can be effectively guaranteed. After the windtight rail clamping device is used, under the condition that the structure safety is sufficiently guaranteed, the structure form of the rail clamping device is effectively used, the aim of windtight fixation of the lazy arm frame under the non-operating state of the high-rise work roof surface can be achieved, and the windtight rail clamping device has the characteristics of being simple in structure, flexible and convenient to operate, humanized, safe, reliable, attractive in appearance and the like. Furthermore, the windtight rail clamping device can be repeatedly used, and is convenient to replace and maintain.
Description
One, technical field
The present invention relates to the safety guard of tower crane, particularly the skyscraper windproof fender guard of roofing arm frame.
Two, background technology
High-building construction often uses roofing to lift up into capable operation, and operating environment is relatively complicated, often meets with the high-altitude strong wind weather, thereby causes the rotation of roofing arm to cause safety misadventure.Therefore it is very important that efficient, simple, failure-free roofing arm wind prevention braking device is set.
Three, summary of the invention
The purpose of this invention is to provide a kind of skyscraper windproof rail clamping device of roofing arm frame, by the rail clamping device device that the roofing arm is fixing in orbit, thereby effectively be implemented in the fixing of roofing arm in the harsh environment such as high-altitude strong wind, avoid roofing to hang safety misadventure, guarantee that roofing hangs the safety of off working state.
The technical solution used in the present invention is: skyscraper is made of a link span and two folder rail plates with roofing arm wind clip rail apparatus, and link span is a flat board, monosymmetric crossbeam is arranged, the baffle plate that has in the crossbeam outer end on the dull and stereotyped following center stand column; Elongated hole is arranged at two folder rail plate tops, and two folder rail plates are hung on the crossbeam of link span both sides by this elongated hole, and there is bolt hole at folder rail plate middle part, is installed with overbolt in bolt hole; Folder rail plate lower inside has groove opposite, and this groove and track shaped upper part adapt.
The arc open-work of symmetry is arranged in the link span both sides, and there is locating dowel pin at the center on link span, and the rail clamping device device is aligned by the arm end joint of locating dowel pin and roofing arm, and by bolt, go up lower bolster, nut and save support through arc open-work and arm end and be connected.The rail clamping device device is in orbit fastening with two folder rail plates by overbolt, bullet pad, circular nut.
By arm rail clamping device device is set in orbit, jib can be fixed on the track, it is windproof to realize that high-rise operation roofing is hung under the off working state jib, thereby effectively guarantees aloft work roofing tower crane machine safety.
The present invention reaches the aloft work roofing and hangs the windproof fixing purpose of off working state jib fully guaranteeing effectively to have utilized track rail clamping device version under the situation of structural safety, have simple in structure, flexible operation is easy, hommization, characteristics such as safe and reliable, good looking appearance.And reusable, repair and replacement are convenient.

Five, the specific embodiment
Skyscraper is made of a link span 1 and two folder rail plates 2 with roofing arm wind clip rail apparatus, and link span 1 is a flat board, monosymmetric crossbeam is arranged, the baffle plate that has in the crossbeam outer end on the dull and stereotyped following center stand column; On folder rail plate 2 tops elongated hole is arranged, two folder rail plates 2 are hung on the crossbeam of link span 1 both sides by this elongated hole, and there is bolt hole at folder rail plate 2 middle parts, are installed with overbolt 3 in bolt hole, and bullet pad 4 and circular nut 5 are arranged on the overbolt 3; Folder rail plate 2 lower inside have groove opposite, and this groove and track 11 shaped upper parts adapt.The arc open-work that symmetry is arranged in link span 1 both sides, there is locating dowel pin 1a at the center on link span 1, the rail clamping device device is aligned by the arm end joint 9 of locating dowel pin 1a and roofing arm, and is connected through arc open-work and arm end joint support 9a by bolt 6, last lower bolster 7, nut 8.
The present invention is by arm rail clamping device device is set in orbit, and by bolt the roofing arm is linked with it, thereby effectively realizes the fixing of roofing arm in the harsh environment such as high-altitude strong wind.
When roofing is hung in mode of operation, roofing arm frame wind clip rail apparatus is fitted together be placed on the appropriate location.
When roofing hangs after operation finishes, the roofing suspension hook is worked rising to the upper limit that hoists, return back to arm end joint 9 and align with track 11 1 sides.Suspension hook 10 is positioned near ground track 11 1 sides to the nutation arm.And jib is returned back to arm end joint 9 align with track 11.Arm is continued to the nutation arm, to stopping during apart from 500mm with track 11 treads.1a positions with locating dowel pin, and the rail clamping device device is assembled on the arm end joint support 9a.Continuation is to the nutation arm, and suitably adjusts link span 1 angle and folder rail plate 2 A/Fs, be installed on the track 11 until press from both sides rail plate 2, and carry out with overbolt 3, bullet pad 4, circular nut 5 fastening, thereby the fixing of realization roofing arm.
