Abstract

The invention discloses a detachable fixed leg structure of a tower crane and is characterized in that a leg bolt is pre-embedded at a base; and the detachable fixed leg is fixed on the surface of the base through the cooperation of the leg bolt and a nut. According to the invention, the problem that the tower crane can not be installed if the horizontal height difference of the fixed leg exceeds standard can be avoided. The detachable leg can be repeatedly used. The cost of the pre-embedded fixed leg is higher than that of the pre-embedded leg bolt by 30-50%. The cost is effectively reduced. The detachable fixed leg structure is generally applicable to foundation construction of a tower crane of less than 500 ton meter, has good practicability, has the outstanding substantive distinguishing features and is significantly improved in comparison with the prior art.

Description

The detachable fixed feet structure of a kind of tower crane
Technical field
The present invention relates to the technical field of mechanical execution, specifically the detachable fixed feet structure of a kind of tower crane, particularly its mechanical connecting structure.
Background technology
Conventional tower crane fixed feet is to be embedded in the concrete basis, as not fixing after the fixed feet location leveling, perhaps watering when smashing concrete, the fixed feet movement that is hit, four leg level height difference surpass national standard, tower crane can not be installed when serious, only have and again do the basis or allow tower crane manufacturer processing nonstandard foundation save to remedy the level height difference of four supporting legs.
Summary of the invention
The object of the present invention is to provide the detachable fixed feet structure of a kind of tower crane, it adopts the form of construction work of pre-buried leg bolt, utilize leg bolt that fixed feet is fixed on base-plates surface, avoid that level height difference exceeds standard between fixed feet, effectively reduce construction cost, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, technical scheme of the present invention is: the detachable fixed feet structure of a kind of tower crane, it comprises pedestal, it is characterized in that: described pedestal place is embedded with leg bolt, and detachable fixed feet matches by leg bolt and nut and is fixed in base-plates surface.
The invention discloses the detachable fixed feet structure of a kind of tower crane, the phenomenon that can avoid the fixed feet level height difference to exceed standard and tower crane can't be installed, detachable leg is reusable, the cost of embedded fixed supporting foot exceeds pre-buried leg bolt 30%-50%, cost effectively reduces, and generally is applicable to the following tower crane foundation construction of 500 tons of rice, has good practicality, compared to existing technologies, have outstanding substantive distinguishing features and marked improvement.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention uses constitution diagram.
The specific embodiment
With reference to the accompanying drawings, the present invention further is described
The present invention is the detachable fixed feet structure of a kind of tower crane, it mainly comprises pedestal 1, it is different from prior art and is: described pedestal 1 place is embedded with leg bolt 2, and detachable fixed feet 3 matches by leg bolt 2 and nut and is fixed in pedestal 1 surface.
For the technological deficiency that exists in the existing construction, carrying out above-mentioned form of construction work improves, embedded fixed supporting foot not when namely making pedestal, but pre-buried leg bolt, with the fixing detachable fixed feet of leg bolt, the method can avoid the fixed feet level height difference to exceed standard, and affects the phenomenon that tower crane is installed.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that implementation of the present invention is confined to above-mentioned these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
