Description
The utility model relates to the climbing device of tower crane auxiliary device, particularly a kind of internal-climbing tower crane.
Existing internal-climbing tower crane is divided into side jacking and two kinds of patterns of central jacking, adopt the tower machine of side jacking, climb in every once need successively upstairs to remove Hydraulic Station, hydraulic ram, in climb framework and bearing beam, not only labor strength is big, and the dismounting trouble, time-consuming.Need not move Hydraulic Station and hydraulic ram though adopt the tower machine of central jacking, but still climb framework, bearing beam and cat ladder in needing to remove in the dismounting, in order to climb framework and bearing beam in installing, often to do specific (special) requirements to the design and construction of elevator, both waste materials, increase cost again, so that have influence on promoting the use of of internal-climbing tower crane.
The applicant once proposed the patent application of a kind of " internal-climbing tower crane ", the patent No.: 96232555.4, this machine partly is made up of body of the tower, tower cap, crane arm, equilibrium arm and hydraulic lifting mechanism etc., feature is to be set with inner climbing jacket frame on body of the tower, the body of the tower bottom is an internal climbing foundation, is set with telescopic girder in the square tube straight beam of inner climbing jacket frame and base, and telescopic girder sets aside in the pre-buried can that is located at hoistway wall, cat ladder is established in the stock both sides, establishes in the body of the tower to promote the inner climbing jacket frame twin drum winch.
This internal-climbing tower crane has replaced with an inner climbing jacket frame climbing framework in three of routine techniques, with light and handy cheap pre-buried can, replaced heavy bearing beam, escalator need not special designs and special construction, in get over journey and all realize mechanization, automation, the practice effect is fine.But still find to have some problems, not proper as inner climbing jacket frame and cat ladder connection mode, internally climbing tower crane stability in the process of climbing is not enough, and skew etc. takes place in body of the tower easily, need further improve.
The purpose of this utility model is exactly on the basis of existing technology, problem at its existence, improve, develop a kind of new internal-climbing tower crane climbing device, the advantage in order to further bringing into play internally climbing tower crane makes it to be more widely used in high-building construction.
The purpose of this utility model is achieved through the following technical solutions:
A kind of internal-climbing tower crane climbing device, form by inner climbing jacket frame, hydraulic lifting mechanism, crossbeam, internal climbing foundation, inner climbing jacket frame is a tower structure, both sides are provided with cat ladder, integral assembling is on body of the tower, body of the tower places in the elevator of building, it is characterized in that: the cat ladder connecting panel adopts the Y type to be welded on two straight beams of inner climbing jacket frame, four jiaos track adjusting wheel is set at inner climbing jacket frame, in being provided with, the inner climbing jacket frame bottom climbs guide frame, in climb four jiaos of guide frame and be provided with track adjusting wheel, inner climbing jacket frame and in climb guide frame four limits be respectively equipped with setting nut and adjustable strut.
Inner climbing jacket frame with in climb guide frame and be linked to be support body by angle steel, make horizontal web member at the support body middle part with angle steel and connect.
On the standard knot web member of body of the tower both sides, the cat ladder guides is installed.
Be provided with guide rail at the cross sill two ends and climb pawl.
Be provided with setting nut and adjustable strut on four limits of internal climbing foundation.
Internal-climbing tower crane climbing device according to the utility model proposes has the following advantages:
The cat ladder connecting panel former with jump weld on two ring beams of inner climbing jacket frame, now change Y shape into and be welded on two straight beams, make the gravity when climbing in the tower machine be decomposed into 4 points, and the two ends of approaching straight beam, thereby improved the force-bearing situation of extending foot by 2.The track adjusting wheel that inner climbing jacket frame is four jiaos with in climb four jiaos of guide frames track adjusting wheel cooperate, rise along straight line when can the control tower machine climbing, make the jacking pressure of hydraulic efficiency pressure system keep stable.
Inner climbing jacket frame, in climb setting nut and adjustable strut be set on guide frame and the internal climbing foundation, when climbing with inner climbing jacket frame and in climb guide frame and be fastened in the elevator, make the unlikely skew in track adjusting wheel position, controlled the squareness that the tower machine climbs effectively.The tower machine climb put in place after, hold out against body of the tower with adjustable strut, can strengthen the stability of tower machine.
3. save original twin drum winch, Hydraulic Station, hydraulic ram are installed in 7～10 meters, body of the tower middle part, can make cat ladder length by original shortening to more than 20 meters in 13 meters,, cat ladder is returned at hydraulic pressure drag unlikely flexural deformation when promoting at the local cat ladder guides of installing of body of the tower.
With inner climbing jacket frame with in climb guide frame and cat ladder is linked to be support body by angle steel, increased intensity, help hydraulic pressure integral body and return to drag to promote in the complete set and climb mechanism.
5. at the cross sill two ends guide rail is set, cross sill is to the skew of body of the tower both sides, the squareness when having guaranteed the jacking of tower machine in the time of can preventing that hydraulic pressure from climbing.
