Background technology
Well cabinet frame and hanging basket often are the equipment that is used for promoting building materials on the building ground, but since building engineering specific working environment and service conditions, various factors, having caused the building ground is the multiple area of safety misadventure, for example elevator is at lifting process, the prominent hypervelocity of meeting, reasons such as steel rope abrasion cause steel rope or the tenesmus out of control of the unexpected disrumpent feelings hanging basket of connecting device, kill or injure personnel by a crashing object.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of well cabinet frame anti-fall device, in case during the weightless tenesmus of hanging basket, this device can in time clamp guide rail, prevents the generation of hanging basket falling accident.The apparatus structure advantages of simple, action in time, and is safe and reliable.
The technical scheme that the utility model adopted is: well cabinet frame anti-fall device is fixed on the hanging basket crossbeam, its constructional feature is that it has the bearing that fixes with the hanging basket crossbeam, pivot shaft is housed in it, the bigger formation head of point diameter of axle, pivot shaft passes the slotted hole that stay bearing plate central authorities offer and can slide up and down in slotted hole, adjustable power assistant spring is equipped with and at the intrinsic tooth bar crossbeam of the head of axle in pivot shaft top, respectively there is a tooth bar fixed thereon below, crossbeam two, spring is all installed in tooth bar top and crossbeam top, two eccentric wheel are fixed by eccentric wheel anchor shaft symmetry in the tooth bar inboard, eccentric wheel is a double-layer structure, internal layer is concentric and have a pick and tooth bar to mesh with axle, outer off-centre also has a cross cut saw tooth, and two pairs of track adjusting wheels that are symmetrical in the stay bearing plate axis are fixed with the track adjusting wheel anchor shaft respectively in the top of tooth bar crossbeam and eccentric below.
Adjustable power assistant spring outside of described pivot shaft top installing is with sheath, and sheath one side and stay bearing plate are fixed, and the contiguous block that links to each other with pivot shaft is withstood in the power assistant spring lower end, and the bottom of regulating bolt is withstood in the upper end.
Described tooth bar crossbeam is symmetrical in the transom bolt of stay bearing plate axis by two and the head of pivot shaft is fixed.
Described tooth bar is fixed on the stay bearing plate with the tooth bar locating piece.
The beneficial effects of the utility model are: after loading onto this anti-fall device on the crossbeam of hanging basket, in case during the weightless tenesmus of hanging basket, this device can in time clamp cooresponding guide rail, effectively prevents the generation of hanging basket falling accident.This apparatus structure advantages of simple, eccentric wheel clamps action and is in time, and performance is safe and reliable.
Description of drawings
Fig. 1 is the site plan of the utility model on well cabinet frame hanging basket crossbeam.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the construction profile scheme drawing after the utility model is cut open along the stay bearing plate axis.
The specific embodiment
As shown in the figure, present embodiment anti-fall device A has two, is contained on the hanging basket crossbeam 1 corresponding to the hanging basket 20 of two guide rails 14 in well cabinet frame diagonal angle, and steel rope 21 1 ends are connected the middle part of hanging basket 20, and the other end links to each other with winch.This device has the bearing 2 that fixes with hanging basket crossbeam 1, pivot shaft 3 is housed in the bearing, the bigger formation head of the point diameter 3-1 of axle, pivot shaft passes the slotted hole 11-1 that stay bearing plate 11 central authorities offer and can slide up and down in slotted hole, head touch the lateral surface of stay bearing plate, adjustable power assistant spring 13 is equipped with on pivot shaft top, be that power assistant spring 13 outsides are with sheath 16, sheath one side and stay bearing plate 11 are fixing, the contiguous block 15 that links to each other with pivot shaft 3 is withstood in the power assistant spring lower end, and the bottom of regulating bolt 17 is withstood in the upper end.Head 3-1 at pivot shaft 3 fixes a tooth bar crossbeam 4 by two transom bolts 18 that are symmetrical in stay bearing plate 11 axis, below, crossbeam two connects tooth bar 5 by spring 19, be that spring 19 is all installed in tooth bar top and crossbeam top, the tooth bar outside is provided with tooth bar locating piece 7.Two eccentric wheel 6 are fixed by eccentric wheel anchor shaft 8 symmetries in the tooth bar inboard, eccentric wheel is a double-layer structure, internal layer is concentric and have a pick and tooth bar 5 to mesh with axle, outer off-centre also has a cross cut saw tooth 6-1, and two pairs of track adjusting wheels 9 that are symmetrical in the stay bearing plate axis are fixed with track adjusting wheel anchor shaft 10 respectively in the below of the top of tooth bar crossbeam 4 and eccentric wheel 6.
This anti-fall device under normal circumstances along with hanging basket crossbeam 1 together about, this moment, pivot shaft 3 was positioned at the upper end of the slotted hole 11-1 that stay bearing plate 11 central authorities offer, power assistant spring 13 is in compressive state, the tooth bar crossbeam 4 that is attached thereto also is positioned at the upper end, tooth bar 5 and eccentric wheel 6 are in reference position, being the tooth bar lower end is meshed with initial tooth on the eccentric wheel, and the sawtooth 6-1 on two eccentric wheel is " eight " word shape, and the guide rail 14 between two eccentric wheel can pass through smoothly; When the weightless for a certain reason tenesmus of hanging basket, bearing 2 and pivot shaft 3 and then fall, the power assistant spring 13 that links to each other with pivot shaft stretches, pivot shaft 3 drops down onto the lower end of slotted hole 11-1, and tooth bar crossbeam 4 also descends, spring 19 compressions of its underpart, tooth bar 5 moves down, the inwardly rotation simultaneously of two eccentric wheel 6, the sawtooth 6-1 on the eccentric wheel goes to level, and the spacing between the two-wheeled is dwindled simultaneously and is tightly clamped moving guide rail 14.Upper and lower two pairs of track adjusting wheels 9 play the effect of balance.
