Abstract

Omnipotent bracing or strutting arrangement bottom a kind of tower crane.Light-duty tower machine generally at least wants 3 ~ 4t, and heavy wants nearly 30t, bears the total weight comprising fuselage bottom tower crane simultaneously, thus bottom it moment all there is potential safety hazard, and affect the life and health of operator and neighbouring resident.Especially tower crane is in the construction of the complicated grounds such as mountain and hill, considers that the factor of bottom strength is more complicated, there is no device at present and address this problem.The utility model comprises: the scalable steel plate in bottom (2), the scalable steel plate in described bottom is connected with scalable base (4), described scalable base is connected with high-strength bolt (10), described high-strength bolt is connected with expansion link lower end (5), and described expansion link top is connected with the scalable steel plate in top (8).The utility model is for reinforcing tower crane bottom strength.

Description

Omnipotent bracing or strutting arrangement bottom a kind of tower crane
One, technical field
The utility model relates to omnipotent bracing or strutting arrangement bottom a kind of tower crane.
Two, background technology
Well-known tower crane is a kind of weight-lifting equipment the most frequently used on building ground, and capstan head machine last time of tower crane all needs to establish counterbalanced weight, and its function is supporting counterbalanced weight, in order to the balancing torque that effect aspect required on Construction designing is contrary with hoisting moment direction.Inversely, and there is certain proportion relation between equilibrium arm length and boom length in the consumption of counterbalanced weight and the length of equilibrium arm.Counterweight is considerable, light-duty tower machine generally at least wants 3 ~ 4t, and heavy wants nearly 30t, bears the total weight comprising fuselage bottom tower crane simultaneously, so bottom it moment all there is potential safety hazard, and affect the life and health of operator and neighbouring resident.Especially tower crane is in the construction of the complicated grounds such as mountain and hill, considers that the factor of bottom strength is more complicated, there is no device at present and address this problem.
Three, summary of the invention
The purpose of this utility model is to provide omnipotent bracing or strutting arrangement bottom a kind of tower crane, solves the deficiencies in the prior art.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: omnipotent bracing or strutting arrangement bottom a kind of tower crane, its composition comprises: the scalable steel plate in bottom, the scalable steel plate in described bottom is connected with scalable base, described scalable base is connected with high-strength bolt, described high-strength bolt is connected with expansion link lower end, and described expansion link top is connected with the scalable steel plate in top.
Omnipotent bracing or strutting arrangement bottom described a kind of tower crane, in the middle of the scalable steel plate in described bottom, latching device is housed, have latching device in the middle of described scalable base, described expansion link is equipped with forced locking device and thru-bolt, in the middle of the scalable steel plate in described top, latching device is housed.The invention has the beneficial effects as follows:
1, the utility model is by the connection of the scalable steel plate in top, the scalable steel plate in bottom, scalable base and expansion link, strengthen the power coming from all directions bottom tower crane, define good support, the size of all directions bearing force can be realized by double end stud.
2, the utility model solves and there is no the technology that device strengthens tower crane bottom strength at present, reduce tower crane cave-in accident rate, make the health of construction worker and nearby residents obtain good guarantee, the present invention simultaneously can be used in the tower crane that various complex-terrain is installed, and substantially increases Occupation coefficient.
Four, accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is birds-eye vieies of accompanying drawing 1.
Accompanying drawing 3 is structural representations of expansion link.
Five, detailed description of the invention
Embodiment 1:
Omnipotent bracing or strutting arrangement bottom a kind of tower crane, its composition comprises: the scalable steel plate 2 in bottom, the scalable steel plate in described bottom is connected with scalable base 4, described scalable base is connected with high-strength bolt 10, described high-strength bolt is connected with expansion link lower end 5, and described expansion link top is connected with the scalable steel plate 8 in top.
Embodiment 2:
Omnipotent bracing or strutting arrangement bottom a kind of tower crane according to example 1, in the middle of the scalable steel plate in described bottom, latching device 1 is housed, latching device 3 is had in the middle of described scalable base, described expansion link is equipped with forced locking device 6 and thru-bolt 7, in the middle of the scalable steel plate in described top, latching device 9 is housed.
