Description
Technical field
The utility model relates to tower crane technical field, particularly relates to one and can dismantle and nonexpondable tower crane foundation.
Background technology
Tower crane is a kind of lifting appliance be most widely used in construction trade, tower crane generally all fixes on the ground, therefore its basis seems particularly important, what traditional tower crane foundation adopted mostly is mode fixed feet being embedded in the underground that ferro-concrete is made, then tower crane is arranged in fixed feet, but this basis can only use once, and make trouble, cost is higher, so be necessary to study the nonexpondable tower crane foundation of a kind of energy.
Utility model content
For overcome existing tower crane foundation can not repeated usage, make trouble, the more high deficiency of cost, technical problem to be solved in the utility model is: provide a kind of detachable and the tower crane rood beam that can reuse is basic.
The utility model solves the technical scheme that its technical matters adopts: tower crane rood beam basis, comprise overarm brace and be arranged on the fixed feet on overarm brace, described overarm brace comprises fixed beam and portable beam, upper and lower surface in the middle part of described fixed beam is provided with connecting panel, the length direction of connecting panel and the length direction of fixed beam perpendicular, described portable beam comprises two, respectively the rotating two ends being arranged on connecting panel.
Further, the weight-bearing surface of described fixed beam and portable beam is provided with substrate, and described substrate is provided with the through hole running through substrate and weight-bearing surface, and described fixed feet is fixed on substrate by bolt and nut.
Further, described substrate is provided with along its length the spaced apart through hole of at least four rows, at least two through holes are drawn together in every package.
Further, pipe link is provided with between described adjacent two fixed feet.
Further, described overarm brace also comprises connection box, and described connection box detouchable is arranged on the side of fixed beam and portable beam, fixed beam and portable beam is connected together.
Further, the weight-bearing surface of described fixed beam and portable beam is also provided with saddle weight.
Further, the weight-bearing surface of described fixed beam is provided with the hoist block facilitating handling.
The beneficial effects of the utility model are: installation is simple, accumulating is convenient, based on the fixed support utilizing fixed beam and portable beam to form, portable beam can be opened during use, formation rood beam basis, then tower machine miscellaneous part is installed on basis, portable beam can not packed up and abut on fixed beam by the used time, basis volume is reduced, be convenient to storage, in addition, because fixed feet position on fixed support is adjustable, make this basis have very strong commonality, be applicable to the hoisting crane of multiple different size.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model when packing up.
Be labeled as in figure, 1-fixed beam, 2-portable beam, 3-fixed feet, 4-weighs face, 5-substrate, 6-connection box, 7-saddle weight, 8-hoist block, 11-connecting panel, 31-pipe link.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises overarm brace and is arranged on the fixed feet 3 on overarm brace, described overarm brace comprises fixed beam 1 and portable beam 2, upper and lower surface in the middle part of described fixed beam 1 is provided with connecting panel 11, the length direction of connecting panel 11 and the length direction of fixed beam 1 perpendicular, described portable beam 2 comprises two, respectively the rotating two ends being arranged on connecting panel 11.Traditional crane foundation directly support and fixed feet is embedded in cement concrete, though structure is stablized, installs trouble, and can only single use, and as needed jenny then must reconstruct basis, therefore cost is higher, easily causes the wasting of resources.The utility model is direct when in use to be put overarm brace on the ground, open portable beam 2, make portable beam 2 vertical with fixed beam 1, form a rood beam basis, ensure that support has enough stability, the fixed feet 3 then on overarm brace is installed tower machine parts; When not in use, Foldable movable beam 2, makes it abut on fixed beam 1, the volume-diminished of whole overarm brace, and can handling easily use to other local continuation, the structure after reducing as shown in Figure 2.
In order to improve the strength and stability of overarm brace, on the weight-bearing surface 4 of fixed beam 1 and portable beam 2, namely be provided with substrate 5 in the place of laying fixed feet 3, described substrate 5 is provided with the through hole running through substrate 5 and weight-bearing surface 4, and described fixed feet 3 is fixing on the substrate 5 by bolt and nut.Fixed feet 3 adopts detouchable mode to be arranged on overarm brace, and object can install different fixed feet 3 according to different hoisting crane models, also can change maintenance easily.
The fixed feet 3 adopted due to different tower cranes may be different, distance between fixed feet 3 is also inconsistent, so be provided with the spaced apart through hole of at least four rows on described substrate 5 along its length, at least two through holes are drawn together in every package, so the fixed feet 3 on every root crossbeam all has at least three positions adjustable on the substrate 5, the leg size that the distance of each position can adopt according to conventional hoisting crane is arranged, thus ensures that this overarm brace has good commonality.
Further, in order to ensure the stability of fixed feet 3, between adjacent two fixed feet 3, be provided with pipe link 31.The mode that pipe link 31 can adopt pin to connect is connected between two fixed feet 3, can fast speed dismounting, and the object of pipe link 31 is the position relationships in order to limit between each fixed feet 3, is convenient to the installation of follow-up tower machine equipment.
In order to improve the stability on whole rood beam basis further, described overarm brace is also provided with connection box 6, described connection box 6 detouchable is arranged on fixed beam 1 and the side of portable beam 2, fixed beam 1 and portable beam 2 is connected together.Connection box 6 preferably arranges four, when needs use time, is first opened by portable beam 2, then connection box 6 is arranged between fixed beam 1 and adjacent portable beam 2, playing support bracket fastened effect, when packing up support, only can unclamp the connection of connection box 6 and portable beam 2.
The weight-bearing surface 4 of described fixed beam 1 is provided with the hoist block 8 facilitating handling.Hoist block 8 can arrange two, and fixed beam 1 is symmetrical arranged, and is convenient to carry out handling and installation with hoisting crane.In order to improve safety, after arranging rood beam basis, saddle weight 7 can be set on the weight-bearing surface 4 of fixed beam 1.
