Column is provided with the drive gear mechanism for coordinating the tooth bar.
Further, when the driven pulley is located at the lower section of the end segments of the side girders, near the hanging crossbeam
The straight pin two of column encounters support column.
When needs are constructed to hanging crossbeam, basket adjustment position in mobility framework is protected at two ends, two protection baskets are made
Spacing be slightly larger than hanging beam width, this programme crossbearer of slinging is placed on hanging crossbeam with lifting machinery, then connects U-lag
Connect while connecting two protection baskets, and workmen is hung in protection basket.Workmen can rely on this programme to hanging crossbeam
The constructing operation for being needed.Deng needs in hanging crossbeam change place, motor is moved on hanging crossbeam with driving wheel.
The beneficial effect of this programme can learn according to the narration to such scheme that simple structure is reasonable in design, makes constructor
Member has foothold, not only there is provided working security, and makes workmen have the strong point in construction, so as to increased
The precision and efficiency of construction of construction, has liberated lifting machinery again.The protection basket on both sides is chosen on hanging crossbeam by this programme crossbearer
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 framework, but above the straight beam end and column between straining beam be set form triangular framing so that straight by one to script
Beam antagonism bending force is changed into the triangular framing by being sequentially connected and rectangular frame antagonism 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 is produced, another opposing are outside
The ability of the anamorphic effect that load action is produced.Former control condition is that the design strength standard value of requirement steelwork component will
More than the stress value that the external loads acted on part are produced in component, this control condition would generally in component tension and
Adopt in the case that the short piece longitudinal axis is pressurized.Latter control condition is requirement steel construction piece by external loads（Mainly pressure,
Moment of flexure, shearing or its combination）There is the ability of enough resistances to deformation under effect, this deformation is probably the bulk deformation of component
The component parts of the excessive forfeiture for causing steel construction piece stability or steel construction piece is excessive because of local deformation（Local buckling）Make structure
Part loses stability.In Practical Project, as steelwork component mostly is elongated member, caused by latter control condition is not enough
The probability of engineering accident is maximum.Meanwhile, steel construction piece stability indicator generally adopt limit stress, due to critical stress value it is usual
Controlled by the slenderness ratio of part, generous the way of restraint when between plate of the plate of building block etc., its value is usually less than etc.
In the strength design standard of steel, the such as stress effect of the part such as the top end transverse member of this programme, joist and bottom end rail greatly
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
Two ends expand outwardly and turn upwards, carry out operation to the relevant position on the upside of hanging crossbeam to prevent side girders from hindering.The end
In the middle part of beam and two ends are provided with support column, make whole end carriage form a stable framework, and increase end carriage shoulders moment of flexure ability, and
And the column at end carriage two ends, moreover it is possible to prevent from protecting basket edge to drop out end carriage, increase safety.Driving wheel and motor are arranged on side
The center of beam and whole scheme, to prevent the equipment such as motor and driving wheel from hampering the operation to hanging beam-end position.Institute
The structure for stating column easily can be moved in mobility framework.The driven pulley is arranged on the protection basket, so as to according to outstanding
During the width adjustment protection basket spacing of empty crossbeam, driven pulley can be constantly in hanging crossbeam by antermarginal position, increase driven
The stability that wheel is supported.The height of driven pulley enables driven pulley to be located at side girders less than the height on the downside of the end segments of side girders
Lower section, enable scheme to be used for the hanging crossbeam operation that width is close to side beam width.Protection basket arranges the fender rod erect, because
During operating personnel's operation, arm move downward upwards it is more, for same point work already often do not need arm transverse shifting.
Pinch wheels mechanism is set, to improve stability, limited block is set, before scheme is put into open, pinch wheels mechanism.Arrange
U-lag, convenient working personnel act on one's own under horizontal sky crossbeam.When operating personnel has not been entered into protection basket, sliding tooth turbine
Structure band carry-over bar leans out, and hooks U-lag and withdraws again, and U-lag crossbearer can both protected between basket at two；Gap and step connection
Place is provided with inclined-plane, spring fixture block to be got into inside tooth bar when tooth bar is contacted with U-lag.
