Abstract
The invention discloses a fixing structure for embedded fixing support arms of a tower crane. The fixed structure is characterized in that a base is longitudinally provided with an adjusting lead screw, the regulation lead screw is spirally connected with an upper adjusting nut and a lower adjusting nut, and a fixing support arm bearing plate is arranged at the adjusting lead screw between the upper adjusting nut and the lower adjusting nut. According to the fixed structure disclosed by the invention, an adjusting lead screw structure is adopted, adjustment on levelnesses of four fixing support arms is easier, only nuts are required to be adjusted, the adjusting lead screw is simpler to process and is lighter in weight compared with a steel stool, processing and transportation costs can be effectively reduced, good practicability is realized, and the fixing structure disclosed by the invention has outstanding substantive characteristics and obvious progress compared with the prior art.
Description
Technical field
The present invention relates to the technical field of mechanical execution, the pre-buried fixed feet fixed sturcture of a kind of specifically tower crane, particularly its mechanical connecting structure.
Background technology
When tower crane is made basic pre-buried fixed feet; Routine is a machined steel stool under fixed feet; And fixed feet is welded on the steel stool, the level attitude of four fixed feet is difficult to accurately adjust, and the volume Shanghai Communications University of steel stool; And weight is heavier, and traffic cost and construction cost are higher.
Summary of the invention
The object of the present invention is to provide the pre-buried fixed feet fixed sturcture of a kind of tower crane, it adopts the adjusting screw structure, can adjust the level height difference of four fixed feet; Accuracy rate is high, and volume is little, and is in light weight; Be convenient to transportation, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals; Technical scheme of the present invention is: the pre-buried fixed feet fixed sturcture of a kind of tower crane; It comprises pedestal; It is characterized in that: said pedestal place vertically is provided with the adjusting screw mandrel, regulates the screw mandrel place and is connected with adjustment nut and following adjustment nut, and the adjusting screw mandrel place between last adjustment nut and the following adjustment nut is provided with the fixed feet bearing plate.
The invention discloses the pre-buried fixed feet fixed sturcture of a kind of tower crane, it adopts adjustable screw structure, and four fixed feet levelness adjustment are than being easier to; As long as setting nut is regulated screw mandrel and compared the processing of steel stool simply, weight ratio steel stool alleviates a lot; Can effectively reduce processing and transportation originally; Have good practicability, compared to existing technologies, have outstanding substantive distinguishing features and marked improvement.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
With reference to the accompanying drawings, the present invention is further described
The present invention is the pre-buried fixed feet fixed sturcture of a kind of tower crane; It mainly comprises pedestal 1; It is different from prior art and is: said pedestal 1 place vertically is provided with and regulates screw mandrel 2; Regulate screw mandrel 2 places and be connected with adjustment nut 3 and following adjustment nut 4, adjusting screw mandrel 2 places between last adjustment nut 3 and the following adjustment nut 4 are provided with fixed feet bearing plate 5.
In the specific implementation, said fixed feet bearing plate 5 is provided with two (cover) and regulates screw mandrel 2, and said fixing leg bearing plate 5 upper surfaces are captiveed joint with fixed feet; During construction; With the level height difference of regulating four fixed feet of screw mandrel adjustment, adjust the back electric welding, and screw mandrel and fixed feet are fixed with reinforcing bar; To prevent that fixed feet moves when the disturbing concrete, influence tower crane and install.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to above-mentioned these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
