Abstract
The utility model discloses a kind of tower crane dynamic equilibrium adjusting apparatus, it is related to Architectural Equipment technical field, including casing, be arranged in parallel two gag lever posts in the casing, the gag lever post two ends are fixedly connected with box body wall, balance plate is provided between two gag lever posts, the balance plate is be arranged in parallel with gag lever post, and bottom and the casing of the balance plate are hinged.The weight at truss two ends can be realized and contrasted by the tower crane dynamic equilibrium adjusting apparatus that the utility model is provided, by the shake-up proximity switch that tilts of balance plate, provide the signal of counterweight movement, it is ensured that counterweight and the balance of lifting goods, reduce the bending stress received of tower body bottom.
Description
Technical field
The utility model is related to Architectural Equipment technical field, and in particular to a kind of tower crane dynamic equilibrium adjusting apparatus.
Background technology
The counterweight of traditional building tower crane is all integrally fixed at the afterbody of truss, and this fixed counterweight mounting means is present
Following shortcoming：Fixed counterweight causes tower crane in unloaded or underloading, and the moment of flexure that tower body bottom is received is larger, is unfavorable for tower
Hang stabilization.Thus, it would be desirable to it is a kind of that the device of balance position can be automatically adjusted according to different magnitudes of load.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of tower crane dynamic equilibrium adjusting apparatus, can be according to load
The weight contrast of lotus and counterweight, provides the movable signal of counterweight, solves tower body bottom stress mistake of the tower crane in unloaded or underloading
Big the problem of.
For realize technical scheme that the purpose of this utility model uses for：A kind of tower crane dynamic equilibrium adjusting apparatus, it is special
Levy and be, including casing, be arranged in parallel two gag lever posts in the casing, the gag lever post two ends are fixedly connected with box body wall,
Balance plate is provided between two gag lever posts, the balance plate be arranged in parallel with gag lever post, bottom and the casing of the balance plate are cut with scissors
Connect.
Further, the both sides of two gag lever posts are respectively provided with a safety pin, the safety pin and the gag lever post
It is arranged in parallel.
Further, the balance plate top is provided with connecting plate, and the connecting plate two ends are symmetrically hinged with lacing wire.
Further, the casing top is provided with two proximity switches, and two proximity switches are relative to balance plate
Place plane is symmetrical.
The beneficial effects of the utility model：
A kind of tower crane dynamic equilibrium adjusting apparatus that the utility model is provided has advantages below：
Installed in the top of tower crane, load-supporting part, the steel wire rope at the lacing wire truss frame for connecting two ends at two ends, the device energy are used as
The weight at truss two ends is realized into contrast, by the shake-up proximity switch that tilts of balance plate, the signal of counterweight movement is provided,
Ensure counterweight and the balance of lifting goods, reduce the bending stress received of tower body bottom.
Brief description of the drawings
Fig. 1 is the structural representation for the tower crane dynamic equilibrium adjusting apparatus that the utility model is provided.
Embodiment
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Fig. 1 show be arranged in parallel in the structure of tower crane dynamic equilibrium adjusting apparatus, including casing 5, casing 5 two it is spacing
Bar 7, the two ends of gag lever post 7 are fixedly connected with box body wall, balance plate 2 are provided between two gag lever posts 7, balance plate 2 and gag lever post 7 are flat
Row is set, and bottom and the casing 5 of balance plate 2 are hinged, and is hinged secondary for an axle 4, that is to say, that balance plate 2 can be relative to axle 4
Rotate.
In order to ensure safety, the both sides of two gag lever posts 7 are respectively provided with a safety pin 6, and safety pin 6 is parallel with gag lever post 7
Set, its position is located at the obliquely downward of gag lever post 7.
The top of balance plate 2 is provided with connecting plate 3, and the two ends of connecting plate 3 are symmetrically hinged with lacing wire 1, and the effect of lacing wire is fixed steel
Cord.
The top of casing 5 is provided with two proximity switches 8, and two proximity switches 8 are symmetrical relative to the place plane of balance plate 2.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this area
Technical staff for, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle within,
Any modification, equivalent substitution and improvements made etc., should be included within protection domain of the present utility model.
