Base is triangular in shape, by three steel pipes, is joined end to end and is formed, and one jiao of triangle base is provided with crosshead, and crosshead is provided with handrail, and a steel pipe relative with handrail is for supporting bottom tube, and door frame is hinged in supporting bottom tube, and the roller of base below is cardan wheel.
Cardan wheel is four, below supporting bottom tube, is provided with three cardan wheels, and the base below at crosshead place is provided with a cardan wheel.
Door frame comprises two columns, and column is telescopic structure, and each column is provided with at least two connecting bores that match with hound.
Each column comprises inner sleeve and the outer tube of suit mutually, and outer tube is connected in base, and the inner sleeve below is provided with spring, and inner sleeve and outer tube are provided with pin-and-hole, and pin fixedly inner sleeve and outer tube relative height are set on pin-and-hole.
Lift system comprises with door frame and slides up and down the airduct bracing frame coordinated, and on the airduct bracing frame, is connected with actuator.
Actuator is the rope that electro-motor drives, or is the piston rod of hydraulic actuating cylinder.
Electro-motor is installed on crosshead, and door frame is during perpendicular to base, and airduct bracing frame and crosshead lay respectively at the both sides of door frame.The beneficial effects of the utility model are to complete efficiently the airduct erection work, and required manpower is few, and labour intensity is low.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation
In figure, be labeled as: the 1-door frame, the 2-base, the 21-crosshead, the 22-roller, 23-supports bottom tube, 3-hound, 4-lift system, 41-airduct bracing frame, 5-rope.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Airduct of the present utility model is installed gig and is comprised base 2 and the door frame 1 be connected with base 2, lift system 4 is installed on door frame 1 and is used for raising airduct.
Because construction site equipment, material are more, therefore adopt the triangle underframe, floor area is few, stabilized structure, adopts three steel pipes or shaped steel at first to be connected and to be welded and fixed and gets final product.Door frame 1 is hinged with base 2, while not using, door frame 1 is fallen to base 2 directions, saves space, also avoids interfering the operation of other operation of building site.Door frame 1 is installed on wherein support bottom tube 23 of triangle underframe, between door frame 1 and base 2, also is provided with hound 3, forms like this gusseted, make door frame 1 firm perpendicular to base 2.
Door frame 1 comprises two telescopic posts, column comprises outer tube and inner sleeve wherein, be equipped with pin-and-hole on it, outer tube is connected with the support bottom tube 23 of base 2, inner sleeve outer tube relatively slides up and down, adjust to suitable position, pin is inserted on pin-and-hole corresponding on inner sleeve and outer tube, in order to adapt to telescopic post, each column is provided with at least two connecting bores that match with hound 3, the height of column just can be fixed like this, when the airduct of differing heights is installed, just can suitably adjust by the column height.
One jiao of triangle base 2 is provided with crosshead 21, and crosshead 21 is provided with handrail, and a steel pipe relative with handrail is the support bottom tube 23 be hinged with door frame.Base 2 belows arrange roller 22, are used for moving easily whole mechanism, and for flexibly mobile, roller 22 all adopts cardan wheel.Cardan wheel is four, be provided with three cardan wheels below supporting bottom tube 23, base 2 belows that crosshead 21 place is one jiao are provided with a cardan wheel, support bottom tube 23 belows 2-5 cardan wheel is set, when slightly there is deviation the airduct position, slightly promote base 2 and can easily correct position be adjusted to in the airduct position, easy to adjust like this, time saving and energy saving.Airduct weight is large, volume is large, by the direct running fix of personnel stood on scaffold, limited by operational space, and working security is low, the Level tune of the lifting by the door frame vertical direction and cardan wheel is by making whole process simple like this, and required personnel amount is less, and efficiency is higher.
Lift system 4 is set on door frame 1, comprises with door frame 1 and slide up and down the airduct bracing frame 41 coordinated, the rope 5 that airduct bracing frame 41 is driven by electro-motor drives, or drives by hydraulic cylinder piston rod.Because the construction site environment is severe, preferably electro-motor drives the scheme that rope 5 promotes airduct bracing frame 41, because airduct bracing frame 41 and crosshead 21 lay respectively at the both sides of door frame 1, electro-motor is arranged on crosshead 21, hound 3 bears tensile stress, the moment of torsion of the opposite direction that 2 pairs of door frames of airduct bracing frame 41 and base produce, both balance each other and make the anterior-posterior balance of holding door frame 1, when promoted airduct weight is larger, can near the base 2 crosshead 21, increase counterweight to increase the moment of torsion of base to door frame 1, guarantee the balance of door frame 1 and base 2, the airduct that goes for like this plurality of specifications and weight is installed.
