When needing to construct to hanging crossbeam, both ends protection basket is adjusted into position in mobility framework, makes two protection baskets
Spacing be slightly larger than hanging beam width, this programme is sling into crossbearer with lifting machinery and is placed on hanging crossbeam, then U-lag is made to connect
It connects while connecting two protection baskets, and construction personnel is hung in into protection basket.Construction personnel can rely on this programme to hanging crossbeam
The constructing operation needed.Deng needs in hanging crossbeam change place, motor is moved with driving wheel on hanging crossbeam.
The advantageous effect of this programme can be simple in structure according to the description of the above program, and reasonable design makes constructor
Member has foothold, not only provides working security, and construction personnel is made to have supporting point in construction, to increase
The precision and construction efficiency of construction, and liberated lifting machinery.This programme crossbearer chooses the protection basket on both sides on hanging crossbeam
Get up, therefore, the safety of the linear beam portion of most stress is most important, thus straight gear is arranged above the straight beam between column and constitutes square
Shape frame, but above the straight beam end and column between setting straining beam form triangular framing, it is straight by one to script to make
Beam confrontation bending force becomes by sequentially connected triangular framing and rectangular frame confrontation bending force.The bearing capacity of steel construction piece
It is mainly reflected in two aspects：One ability for being resistant to the stress effect that external loads effect generates, another resists external
The ability for the anamorphic effect that load action generates.Former control condition is that the design strength standard value of requirement steelwork component is wanted
More than the stress value that the external loads acted on component generate in component, this control condition would generally in component tension and
The short piece longitudinal axis uses in the case of being pressurized.Latter control condition is requirement steel construction piece by external loads（Mainly pressure,
Moment of flexure, shearing or a combination thereof）It may be the overall deformation of component to have the ability of enough resistances to deformation, this deformation under effect
The component parts of the excessive forfeiture for leading to steel construction piece stability or steel construction piece is excessive because of local deformation（Local buckling）Make structure
Part loses stability.In Practical Project, since steelwork component is mostly elongated member, caused by latter control condition deficiency
The probability of engineering accident is maximum.Meanwhile steel construction piece stability indicator generally use limit stress, since critical stress value is usual
By the slenderness ratio of component, the plate of building block generous when plate between the controls such as the way of restraint, value is usually less than etc.
In stress effect a big chunk of the strength design standard of steel, such as the top end transverse member of this programme, joist and bottom end rail component
Come from moment of flexure, because when resist torque causes to deform, while just having resisted stress rupture caused by moment of flexure.Side girders
Both ends expand outwardly and turn upwards, and operation is carried out to the corresponding position on the upside of hanging crossbeam to prevent side girders from interfering.The end
In the middle part of beam and it is provided at both ends with support column, so that entire end carriage is formed a stable frame, increases the bending resistance square ability of end carriage,
And the column at end carriage both ends, moreover it is possible to prevent protection basket edge from dropping out end carriage, increase safety.Driving wheel and motor are arranged in side
The center of side bar and entire scheme, to prevent the equipment such as motor and driving wheel from hampering the operation to hanging beam-end position.
The structure of the column can be moved easily in mobility framework.The driven wheel is arranged on the protection basket, so as to basis
When the width adjustment protection basket spacing of hanging crossbeam, driven wheel can be constantly in the position that hanging crossbeam leans on proximal edge, increase from
The stability of driving wheel support.The height of driven wheel enables driven wheel to be located at side less than the height on the downside of the end segments of side girders
The lower section of beam enables scheme to be used for hanging crossbeam operation of the width close to side beam width.The fender rod for protecting basket setting to erect,
When because of operating personnel's operation, arm moves downward more upwards, does not often need the lateral of arm for the operation of same point and moves
It is dynamic.Pinch wheels mechanism is set, to improve stability, limited block is set, before being put into scheme to open, pinch wheels mechanism.
U-lag is set, and convenient working personnel act on one's own under horizontal empty crossbeam.When operating personnel has not been entered into protection basket, sliding tooth
Wheel mechanism drives rack to lean out, and hooks U-lag and withdraws again, U-lag crossbearer can both protected at two between basket；Gap and step
Junction is provided with inclined-plane, to get into spring fixture block inside rack when rack and U-lag contact.
