Abstract
The invention discloses a hanging scaffold structure of a tower crane, which comprises a hanging scaffold and a hanging arm capable of sliding relative to the hanging scaffold. The hanging scaffold structure is characterized in that the hanging scaffold is provided with a first hanging rope hole, a second hanging rope hole and a third hanging rope hole; mutual connection lines of the first hanging rope hole, the second hanging rope hole and the third hanging rope hole form a regular triangle; and a first hanging rope, a second hanging rope and a third hanging rope penetrate through the first hanging rope hole, the second hanging rope hole and the third hanging rope hole and are combined at a point. With the adoption of the technical scheme, the swinging amplitude of the hanging ropes can be effectively alleviated during object hoisting, so that the purposes of making a hoisting position precise and protecting ground operation personnel are achieved.
Description
Technical field
The present invention relates to tower crane apparatus field, especially relate to a kind of hanging scaffold structure of tower crane.
Background technology
Tower crane is a kind of weight-lifting equipment the most frequently used on building ground, with a section spreading (height) (be called for short " standard knot "), is used for the raw MAT'L of the constructions such as the reinforcing bar of lifting construction, wood are stupefied, cement concrete, steel pipe.The arm of tower crane is provided with and connects the hanging scaffold of lifting rope, change lifting rope length and raise by mobile hanging scaffold or reduce hoisting object, carry out horizontal movement by swinging boom.
In the prior art; tower crane is when hoisting object; suspension hook can be provided with in the bottom of lifting rope; by object is lifted on suspension hook; thus carry out up and down or the movement of horizontal direction, especially when carrying out horizontal direction mobile, can there is the swing of different amplitude in lifting rope usually; both had influence on the particularity of object Hoisting Position, again serious security threat had been caused to the safety of ground operating personnel.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the hanging scaffold structure proposing a kind of tower crane.
Object of the present invention will be achieved by the following technical programs: a kind of hanging scaffold structure of tower crane, comprise: hanging scaffold, can with the arm of described hanging scaffold relative sliding, described hanging scaffold is provided with the first lifting rope hole that mutual line is equilateral triangle, the second lifting rope hole and the 3rd lifting rope hole, wherein, first lifting rope, the second lifting rope and the 3rd lifting rope are each passed through described first lifting rope hole, the second lifting rope hole and the 3rd lifting rope hole, and the first lifting rope, the second lifting rope and the 3rd lifting rope are incorporated into a bit.
Preferably, the hanging scaffold structure of above-mentioned a kind of tower crane, described hanging scaffold is connected by pulley with described arm.
Preferably, the hanging scaffold structure of above-mentioned a kind of tower crane, the shape of described hanging scaffold is circular or square.
Preferably, the hanging scaffold structure of above-mentioned a kind of tower crane, the length of described first lifting rope, the second lifting rope and the 3rd lifting rope is equal.
Outstanding effect of the present invention is: 1) by arranging the lifting rope hole of equilateral triangle on hanging scaffold, positive triangular pyramid can be formed in solid space by the lifting rope in lifting rope hole, in the junction hoisting object of three lifting ropes, when moving in the horizontal direction, the amplitude of swing can be reduced; 2) length of three lifting ropes is equal, can ensure that the power that it acts on three lifting ropes is identical, be unlikely to situations such as toppling when hoisting object.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the hanging scaffold structural representation of the tower crane of the present embodiment.
Detailed description of the invention
As shown in Figure 1, the hanging scaffold structure of a kind of tower crane of the present embodiment, comprise: hanging scaffold 1, can with the arm 2 of hanging scaffold 1 relative sliding, hanging scaffold 1 is provided with the first lifting rope hole 102, lifting rope hole 101, second and the 3rd lifting rope hole 103 that mutual line is equilateral triangle, wherein, the first lifting rope 3, second lifting rope 4 and the 3rd lifting rope 5 are each passed through the first lifting rope hole 102, lifting rope hole 101, second and the 3rd lifting rope hole 103, and the first lifting rope 3, second lifting rope 4 and the 3rd lifting rope 5 are incorporated into a bit.
First lifting rope 3 and the second lifting rope 4, the 3rd lifting rope 5 be combined with each other on one point, under mutual line is the first lifting rope hole 102, lifting rope hole 101, second of equilateral triangle and the effect in the 3rd lifting rope hole 103, object for lifting can keep it to have good stability, can not occur significantly to rock, and, first lifting rope 3 is equal with the length of the second lifting rope 4, the 3rd lifting rope 5, can ensure that it reaches the object of synchronization action.
Concrete, hanging scaffold 1 is connected by pulley 6 with arm 2, because hanging scaffold 1 needs the height changing hoisting object with arm 2 relative sliding, it can be made to reach the state of normal work by the connection of pulley 6.
Concrete, the shape of hanging scaffold 1 is circular or square, and the shape of rule is conducive on hanging scaffold 1, offer the lifting rope hole that line is equilateral triangle, but is not limited only to the shape of rule, and those skilled in the art are without the need to creative work and available scheme.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
