Abstract

The invention provides a pulley-type suspension device of a large load high-place operation nacelle. The suspension device comprises a suspension mechanism and an elevator mounting rack. The suspension mechanism is composed of a pulley, suspension racks, connection sleeves, front beams, upper standing columns, inserted links, a front base, middle beams, obliquely-drawn steel wire ropes, rope sheaves, back beams, a back base and balancing weights. The suspension mechanism is arranged in a parallel structure. The mounting rack is composed of a safe lock mounting clamp, a safe lock guide rope sheave, an elevator mounting clamp, a crossbeam and a standing column. The mounting rack and the suspension mechanism form a whole suspension device. In the suspension device, through reasonable arrangement and structural design, the loading condition of the suspension mechanism is improved through the pulley, the problems caused by designed three-suspension or multi-suspension complex platform structures because of insufficient strengthen of a suspension mechanism of a large load nacelle is solved, and the self weight of nacelle structure is reduced. Compared with existing suspension mechanisms, the suspension device is convenient to disassemble and assemble, has a simple in structure and good mechanical properties, and can meet construction requirements of a large load high-place operation nacelle to a greater extent.

Description

Large load aerial work basket pulley-type suspension gear
Technical field
The present invention relates to aerial work basket pulley-type suspension gear in technical field of buildings, especially relate to large load, large span aerial work basket for the aerial work basket pulley-type suspension gear of large load high-rise working.
Background technology
Along with the fast development of the industries such as China's building curtain wall, Steel Structure Installation, aerial work basket is as the important component part of high-altitude construction equipment, and the use in the building operation such as curtain wall installation, elevator installation is increasingly extensive.At present, the curtain wall that monolithic weight surpasses 500kg increases gradually, and the load-carrying capacity of domestic existing aerial work basket is mostly between 250kg ~ 800kg, the large load aerial work basket that load carrying ability surpasses 3000kg still belongs to blank, outstanding day by day to the demand of large load aerial work basket.Suspension gear, as the anchor fitting of the whole equipment of aerial work basket, bears main working load, reliability and security when its structural strength and rigidity are determining aerial work basket work.The present invention carries out innovative design to important load bearing component suspension gear, meeting on the whole basis requiring, obtain improved pulley-type hitch device, for research and development and the technological advance of large load aerial work basket lays the foundation, the design and R&D of like product is had to certain directive significance.
Summary of the invention
The object of this invention is to provide a kind of large load aerial work basket pulley-type suspension gear, it is applicable to large load, large span aerial work basket.
For achieving the above object, the present invention is achieved through the following technical solutions the present invention:
Hitch is mainly comprised of pulley, hanger bracket, adapter sleeve, front-axle beam, upper pillar stand, inserted link, front stall, central sill, oblique pull steel rope, rope sheave, the back rest, back seat, counterweight; Elevator mounting frame is mainly comprised of safety lock mounting clamp, safety lock sheave, steel rope tight pulley, hoist installation folder, crossbeam and column.It is characterized in that: the load cable passing from gig during work is walked around the pulley of safety lock sheave and hitch front-axle beam and is fixed on elevator mounting frame steel rope tight pulley and clips with rope clamp, motor drives friction wheel rotating by transmission device, force the dynamic load of gig band upwards climb or move downward along steel rope along steel rope, realize the lifting of high-rise working suspension platform.
Before hitch, two groups of hanger brackets of beam end are bolted, while being fixed on elevator mounting frame steel rope tight pulley when the load cable passing from gig is walked around the pulley of safety lock sheave and hitch front-axle beam, application fixed pulley component principle, to outside mechanism, carry and be uniformly distributed in hitch frame, reach and improve hitch stressing conditions, improve the object of hitch load-carrying capacity.
Compared with prior art, the present invention has the following advantages and effect: the hitch of the present invention's design, by rational deployment, utilizes the principle of pulley component, reduces the external bearer of single traditional hitch and single wire rope, has improved the intensity of suspension gear; by the layout of hitch and erecting frame, solved large load hanging basket because of three suspension centres or many suspension centres complex platform structure problem that hitch undercapacity designs, platform structure is simplified, alleviated the deadweight of barrel structure; suspension gear has the features such as easy accessibility, structure stress is good, synchronism is strong, improves more the lifting load ability of aerial work basket.
Accompanying drawing explanation
Fig. 1 aerial work basket pulley-type of the present invention hitch whole 3D solid structural representation of constructing.
Fig. 2 aerial work basket pulley-type of the present invention hitch 3D solid structural representation.
The concrete schematic layout pattern of Fig. 3 middle pulley of the present invention.
The front stall scheme of installation of hitch in Fig. 4 the present invention.
In Fig. 5 the present invention, steel rope is at erecting frame schematic layout pattern.
The specific embodiment
In Fig. 1, aerial work basket is divided into five major parts, is respectively hitch 20, safety lock 22, elevator mounting frame 23, gig 24 and suspension platform 25.Two groups of pulley-type hitches and suspension platform reasonable Arrangement during work, the load cable 21 passing from gig is walked around the pulley of safety lock sheave and hitch front-axle beam and is fixed on elevator mounting frame steel rope tight pulley and clips with rope clamp, motor drives friction wheel rotating by transmission device, force the dynamic load of gig band upwards climb or move downward along steel rope along steel rope, realize the lifting of aerial work basket suspension platform.Because load cable is walked around the pulley of hitch front-axle beam, half that the speed that load is risen and declined is Hoist Speed, thus reduced dynamic impulsion platform structure being brought because hoisting, braking.
As hitch in Fig. 2 is comprised of pulley 1, hanger bracket 2, adapter sleeve 3, front-axle beam 4, upper pillar stand 5, inserted link 6, front stall 7, central sill 8, oblique pull steel rope 9, rope sheave 10, the back rest 11, back seat 12, counterweight 13.A pulley 1 is settled in two groups of structure front-axle beam placed side by side 4 ends, 2 of two hanger brackets of pulley 1 and front-axle beam 4 ends are with bolts, the load cable passing from gig during work is walked around the pulley of hitch front-axle beam 1 and is fixed on elevator mounting frame, motor drives friction wheel rotating by transmission device, force the dynamic load of gig band upwards climb or move downward along steel rope along steel rope, realize the lifting of high-rise working suspension platform.
If Fig. 3 is the concrete schematic layout pattern of pulley, the fixed pulley 1 of winding work steel rope is connected with hanger bracket 2 by bolt, and hanger bracket 2 is also bolted with front-axle beam 4, and this layout can complete the transmission of power well.
As the front stall scheme of installation that Fig. 4 is hitch, inserted link 6 inserts front stall 7, with bolts.Standard is simple, easy to operate.
If Fig. 5 is elevator mounting frame schematic diagram, mainly by hoist installation folder 14, safety lock sheave 15, steel rope tight pulley 16, column 17, crossbeam 18 and safety lock mounting clamp 19, formed.The load cable passing from gig is walked around safety lock sheave 15, through safety lock, walk around again the pulley of hitch front-axle beam and get back to erecting frame steel rope tight pulley 16, utilize rope clamp to clamp, structure has been avoided the mutual winding of load cable, reduce the bearing load of single wire rope, when being beneficial to platform safety lifting, improved the life-span of steel rope.After all parts are got all the ready, with reference to accompanying drawing, install.
