Abstract
The invention relates to a rigidity-variable flexible adhering and damping device for a tower crane. The device comprises lug plates, inner rods, an outer pipe, a plurality of fixed holes, inner rod end parts, springs, dampers, fixed pin shafts and a cover plate, wherein the lug plates include a left lug plate and a right lug plate which are respectively fixed at the tower crane and an adhering wall, the springs sleeve the inner rods, two ends of the springs are respectively fixed at the inner rod end parts and outer pipe end parts, the fixed holes of same diameters are formed in the outer pipe and the inner rod end parts, the inner rod end parts are in clearance fit with the outer pipes so as to guide the sliding of the inner rods in the outer pipe, and the dampers are respectively fixed at the end parts of left and right inner rods. The rigidity-variable flexible adhering and damping device has the beneficial effect that the adaptability is high, the tower crane can be effectively supported, the vibration caused due to dynamic load and wind load can be eliminated, the stability is improved, and meanwhile, the overlarge stress is prevented.
Description
Technical field
The present invention relates to tower crane technical field, specifically a kind of tower crane Upon Flexible Adhesion shock absorption device of stiffness variable.
Background technology
Tower crane bears a lot of load in the course of the work, along with increasing and the lifting of height of tower joint, need be attached to and on building, ensure stability.Prior art is mainly rigid attachment, when reply sudden applied load, can produce larger stress, harm tower machine safety.And lack the attachment device that becomes rigidity, be difficult to adapt to the demand of different loads.
Summary of the invention
The object of the invention is to solve stability and the safety issue of tower crane in existing technology, a kind of tower crane Upon Flexible Adhesion shock absorption device of stiffness variable is provided.
The technical solution used in the present invention is: a kind of tower crane Upon Flexible Adhesion shock absorption device of stiffness variable, comprises otic placode, interior bar, outer tube, fixed orifice, interior boom end, spring, damper, fixed pin shaft and cover plate.Described otic placode is divided into left and right otic placode, be separately fixed at tower crane and adhere on wall, interior bar is divided into bar in left and right, interior boom end and outer tube are free-running fit, for the slip within the outer tube of interior bar play the guiding role, spring housing is on interior bar, and both ends of the spring is individually fixed in interior boom end and outer tube end, damper is fixed on boom end in left and right, for horizontally slipping of interior bar provides damping.
Described outer tube and interior boom end are drilled with all identical fixed orifices of several diameters, by fixed pin shaft, interior bar are fixed on outer tube, in order to the collapsing length of regulating spring, regulate the object of adhering to shock absorption device rigidity thereby reach.
Described outer tube is provided with cover plate, is drilled with the through hole identical with through hole diameter on outer tube on cover plate, ensures that fixed pin shaft Joint strenght is loosening.
The outstanding advantage of the present invention is:
1, strong adaptability, several fixed positions provide several adjustable rigidity, can adapt to the different operating modes such as underloading and heavy duty.
2, rigidity and flexible combination can provide effective support for tower crane, can eliminate again dynamic load and wind and carry the vibration causing, prevent the generation of excessive stresses when improving stability.
Brief description of the drawings:

Fig. 2 is the inner structure schematic diagram of the tower crane Upon Flexible Adhesion shock absorption device of stiffness variable of the present invention.
Fig. 3 be in Fig. 1 A-A to cutaway view.
Parts title and sequence number in figure: otic placode 1, interior bar 2, outer tube 3, fixed orifice 4, interior boom end 5, spring 6, damper 7, fixed pin shaft 8, cover plate 9.
Detailed description of the invention:
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
As depicted in figs. 1 and 2, the tower crane Upon Flexible Adhesion shock absorption device of stiffness variable of the present invention, comprise otic placode 1, interior bar 2, outer tube 3, fixed orifice 4, interior boom end 5, spring 6, damper 7, fixed pin shaft 8 and cover plate 9, described otic placode 1 is divided into left and right otic placode, be separately fixed at tower crane and adhere on wall, interior bar 2 is divided into bar in left and right, interior boom end 5 is free-running fit with outer tube 3, for the slip of interior bar 2 in outer tube 3 play the guiding role, spring 6 is enclosed within on interior bar 2, spring 6 two ends are individually fixed in interior boom end 5 and outer tube end, damper 7 is fixed on boom end in left and right, for horizontally slipping of interior bar 2 provides damping.
Described outer tube 3 and interior boom end 5 are drilled with all identical fixed orifices 4 of several diameters, can interior bar 2 be fixed on outer tube 3 by fixed pin shaft 8.
As shown in Figure 3, described outer tube is provided with cover plate 9, is drilled with the through hole identical with through hole diameter on outer tube 3 on cover plate 9, ensures that fixed pin shaft 8 Joint strenghts are loosening.
In the time that boom end in left and right 5 is fixed on different fixed orifices 4, the initial collapsing length of spring 6 changes, thereby has regulated the rigidity of originally adhering to shock absorption device.In the time that bar in left and right 2 is all fixed, originally adhering to shock absorption device is rigidity, and now damper 7 is inoperative.By interior boom end 5 is fixed on to different fixed orifice 4, regulates whole length of adhering to shock absorption device, thereby adapt to tower crane and the different spacing of adhering to wall.
Adjustable while of rigidity of the present invention also provides necessary damping, can provide effective rigid support for tower crane, also can eliminate dynamic load and wind and carry the vibration causing, and not cause excessive counter-force, and the reinforcing that can be widely used in tower crane is supported.
