Abstract
The utility model discloses a tower crane tilting prevention structure.A tower crane upright post is provided with a connecting support, the connecting support is provided with 2 jacks, the piston end of each jack is in shaft connection with an anchor ear, the bottom end of each anchor ear is in shaft connection with the connecting support, each anchor ear is semicircular, and a circle formed by folding the 2 anchor ears is tightly held outside a fan upright post. The utility model has the advantages that: because the stability of the fan stand column is fully utilized, the influence of wind power on the tower crane is overcome, the shaking of the tower crane during construction is avoided, and the construction safety is ensured.
Description
Technical Field
The utility model relates to the field of engineering machinery, in particular to a crane, and more particularly relates to an anti-dumping device.
Background
In a wind power construction site, fan blades are required to be installed on a fan upright post through a tower crane with the height of more than 100 meters; because wind power generation drives the fan blades to rotate by utilizing wind energy, a construction site is generally arranged at a higher position with larger wind power; the tower crane is too high, and the wind power is not stable, so the wind power very causes the shaking of the tower crane, and the construction is difficult; even scrape the tower crane down when serious, cause great loss.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model aims to provide a tower crane anti-falling structure, wherein a tower crane upright post is provided with a connecting support, 2 jacks are arranged on the connecting support, the piston end of each jack is in shaft connection with a hoop, the bottom end of each hoop is in shaft connection with the connecting support, the hoop is semicircular, and a circle formed by folding the 2 hoops is tightly held outside a fan upright post.
In order to adjust the height of the connecting support at the tower crane upright post conveniently, the connecting support is arranged on the slideway, and the upper end of the connecting support is connected with the winch through a sling.
The other structure is that the connecting support is a plurality of and is respectively arranged at different heights of the tower crane upright post, so that the tower crane upright post and the fan upright post can be combined into a whole more firmly.
In order to prevent the looseness of the hoop, the tail end of the hoop is provided with a locking device.
The utility model has the advantages that: because the stability of the fan stand column is fully utilized, the influence of wind power on the tower crane is overcome, the shaking of the tower crane during construction is avoided, and the construction safety is ensured.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of fig. 1.
Detailed Description
The utility model is specifically described below with reference to the accompanying drawings, as shown in the figures, a tower crane base 2 is fixed on a tower crane supporting leg 1, and a tower crane upright post 3 is fixed on the tower crane base 2; the tower crane stand upper end sets up general hoisting accessory, and figure 1 is the local schematic diagram of tower crane stand, and the upper end of tower crane stand is general structure, therefore omits.
Set up connection support 4 on tower crane stand 3, connection support is metal welded frame construction, can lighten weight and guarantee the stability of structure like this, and the one end that is close to the tower crane stand can the suit on the slide, and the slide can be columnar structure 9, connects the support and sets up the through-hole suit and is in the outer end of slide, the upper end of connecting the support is passed through the hoist cable and is connected with the hoist engine, just so can adjust the height of connecting the support.
A shaft seat is arranged at one end of the connecting support 4 close to the fan upright post 5, and the bottom end of a semicircular hoop 7 is coupled on the shaft seat; the connecting support is provided with 2 jacks 6, the piston ends of the jacks are in shaft connection with the hoops, and the circular hoops formed by folding the 2 hoops are tightly held outside the fan upright post 5.
The other structure is that the connecting support is a plurality of and is respectively arranged at different heights of the tower crane upright post, so that the tower crane upright post and the fan upright post can be combined into a whole more firmly.
For preventing not hard up of staple bolt, the end of staple bolt sets up locking device, locking structure can be the bolt and pass the terminal through-hole of staple bolt, the staple bolt end can set up a plurality of through-holes, and like this, the combination of usable different through-holes corresponds the fan stand of different diameters.
The fan stand is fixed on fan basis 8.
