Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
Example 1
As shown in fig. 1 and 2, the combined type universal foundation is cross-shaped and high in support stability, and comprises a fixing part and a moving part, wherein the fixing part comprises a bolt assembly, concrete arranged at the lower part of the bolt assembly and an installation plate 5 arranged on the concrete, and the bolt assembly is composed of a plurality of embedded bolts 1;
the movable part comprises a box body 2, a pressing block assembly 3 and supporting legs 4 which are installed on an installation plate 5, the box body 2 is placed on the installation plate 5, the supporting legs 4 are installed on the box body 2, and the pressing block assembly 3 is installed at the upper end of the embedded bolt 1 and compresses the box body 2. According to the invention, a plurality of high-strength bolts are embedded in concrete, a box body 2 is used for bearing main load outside the concrete, the embedded bolts 1 are connected with a plurality of pressing block assemblies 3 and tightly press the box body 2, the box body 2 is connected with a supporting leg structure through a flange plate, and the supporting leg is connected with a tower body. When the tower crane is required to be installed in a switching mode, the universal operation can be realized only by moving the position of the rigid box body, changing the installation position of the pressing block assembly and replacing the supporting legs.
As an improvement of the embodiment, as shown in fig. 1 and 2, the embedded bolt 1 is an embedded part, the lower part of the embedded bolt 1 is embedded in a concrete foundation (concrete), the relative position is not changeable, the upper part of the embedded bolt 1 is exposed, the exposed length is higher than the total height of the box body 2 and the pressing block assembly 3, and a nut is conveniently mounted subsequently, so as to fasten the box body 2 and the pressing block assembly 3. The actual arrangement quantity of the embedded bolts 1 is more than the actual use quantity, when the distance between the supporting legs 4 is changed by moving the box body 2, the connecting position or the quantity of the pressing block assembly 3 and the embedded bolts 1 needs to be adjusted, so that the pressing block assembly 3 is ensured to completely press the box body 2, and the basic universality can be realized.
As the improvement of embodiment, the upper end of box 2 pass through the ring flange with landing leg 4 is connected, and the landing leg dismouting is convenient, switches installation tower machine efficient.
As an improvement of the embodiment, as shown in fig. 1, four groups of embedded bolts 1 are provided, and a box body 2 and a plurality of briquetting assemblies 3 are arranged in each group of embedded bolts 1. Specifically, each group of embedded bolts 1 comprises two lines of bolts, the two lines of bolts are symmetrically arranged on two sides of the box body 2, one pressing block assembly 3 is connected between the two opposite bolts, the pressing block assemblies 3 can be tightly pressed on the box body 2 through screwing nuts, and the strength requirements of tower cranes of different models can be met by adjusting the using quantity of the pressing block assemblies 3.
As the further improvement of the embodiment, the pressing block assembly 3 comprises a rectangular pressing block and a gasket, the square pressing block is installed on the embedded bolt 1 through the nut matched with the gasket, the installation position of the pressing block assembly is convenient to change, the bottom of the pressing block is tightly pressed at the two ends of the box body 2, and the connection is more stable.
As the improvement of the embodiment, a plurality of mounting holes are formed in the two ends of the mounting plate 5, and the embedded bolts 1 penetrate through the mounting holes in the mounting plate 5, so that the mounting plate 5 is ensured to be horizontal and stable.
In addition, the installation method of the combined type universal foundation comprises the following steps: embedding bolts in concrete, then installing an installation plate 5 on the embedded bolts 1, placing a box body 2 on the installation plate 5, fastening the box body with a pressing block assembly 3, and connecting a tower body through supporting legs 4 on the box body 2;
when the tower crane needs to be switched and installed, the box body 2 is moved, the installation position of the pressing block assembly 3 is changed, and the supporting legs 4 are replaced.
During the concrete use, as shown in fig. 3, when the foundation is changed to different landing legs to connect different types of tower cranes, the reason for changing the foundation from fig. 3 (a) to fig. 3 (b) is that L1 is different from L2, namely, the distance between the center lines of the tower body main chord of the installed tower crane is different, under the condition that the position of the embedded bolt 1 is not changed, the pressing block component 3 pressed on the box body 2 needs to be removed first, the placement position of the box body 2 is adjusted (the distance between the box bodies 2 is reduced), the pressing block component 3 is pressed again, it needs to be ensured that the pressing block component 3 can be completely pressed on the box body 2, and it can be found that the embedded bolt 1 used at the moment (namely, connected with the pressing block component 3) is different from the embedded bolt 1 used before the adjustment.
When the tower cranes are required to be installed in a switching mode, the combined universal foundation can be used universally only by moving the position of the rigid box body, changing the installation position of the pressing block assembly and replacing the supporting legs, so that the tower cranes with large tonnage differences use one set of foundation together, resource waste and cost are reduced, and reasonable utilization of materials is realized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
