Abstract
The utility model discloses a rotary lifting bent which comprises a lifting beam. An upper lifting lug for connecting a gantry crane is arranged at the middle part of the lifting beam; a plurality of fixed pulleys are vertically arranged at the lower part of the lifting beam through rotating shafts. The rotary lifting bent can correspondingly change the directions of the fixed pulleys according to the arrangement directions of lifting points and better solve the problem that steel wire ropes intertwine due to identical directions of the sectional lifting points and the pulleys of the lifting bent.
Description
Technical field
The utility model relates to a kind of row of hanging, particularly a kind of rotary row of hanging.
Background technology
In manufacture, gauntry crane is mainly used in the large-scale segmentation of lifting.Because the suspension centre of large-scale segmentation is more, the horizontal and vertical suspension centre that all is furnished with in segmentation, be used to that to hang lifting be changeless with the pulley of steel rope or the direction of assembly pulley and general non-rotating hangs the row bottom, so be easy to take place phenomenon owing to segmentation suspension centre and the inconsistent steel rope winding that causes of pulley direction.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the defective that the steel rope wrapping phenomena takes place easily in the row of hanging of the prior art, a kind of rotary row of hanging that can avoid the generation of steel rope wrapping phenomena to be provided.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of rotary row of hanging, and its characteristics are that it comprises: a hanging beam, its middle part is provided with a last hanger that is used to connect gauntry crane; Hang down by S. A. and be provided with a plurality of fixed pulleys in the bottom of this hanging beam.
Wherein, this fixed pulley is 360 degree with respect to the rotating range of this S. A..
Preferably, this hanging beam comprises a main hanging beam and two auxiliary hanging beams that are connected in the two ends, bottom of this main hanging beam, and hanger is located at the middle part of this main hanging beam on this, and these a plurality of fixed pulleys are divided into two groups of bottoms of being located at these two auxiliary hanging beams respectively.
Preferably, each should be assisted the hanging beam bottom to hang down and be provided with two fixed pulleys.
Wherein, articulate by adapter shaft between this auxiliary hanging beam and the main hanging beam.
Wherein, in perpendicular, this auxiliary hanging beam is spent positive 15 degree with respect to the rotating range of this adapter shaft for negative 15.
Preferably, the lower central of this main hanging beam also is provided with an assembly pulley.
Wherein, this assembly pulley comprises two fixed pulleys that are parallel to each other.
Positive progressive effect of the present utility model is: this rotary row of hanging can correspondingly change the direction of pulley according to the direction that suspension centre is arranged, has solved the phenomenon of twining owing to the inconsistent steel rope that produces of segmentation suspension centre and the row's of hanging pulley direction well.This has reduced the goods and materials that handling consumed, and has reduced working strength of workers, has improved production efficiency, has shortened the manufacturing cycle, and makes whole handling safe and reliable.In addition,, further improved the stressed distribution when lifting by crane, improved the safety of handling by the auxiliary hanging beam that can adjust angle is set.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model.
Fig. 2 is the section drawing along A-A ' direction among Fig. 1.
Fig. 3 is the section drawing along B-B ' direction among Fig. 1.
The specific embodiment
Enumerate preferred embodiment below in conjunction with accompanying drawing, with the clearer the utility model that intactly illustrates.
Of the present utility modelly rotaryly hang package and draw together: a hanging beam, its middle part are provided with a last hanger that is used to connect the gauntry crane suspension hook; Hang down by S. A. and be provided with a plurality of fixed pulleys in the bottom of this hanging beam.Figure 1 shows that the structural representation of the rotary row's of hanging an of the present utility model embodiment, in this embodiment, this hanging beam comprises a main hanging beam 1 and two auxiliary hanging beams 2 that are articulated in the two ends, bottom of this main hanging beam 1 by adapter shaft symmetrically, being somebody's turn to do auxiliary hanging beam 2 can be in perpendicular, be in the paper plane shown in Figure 1, in the scopes of positive and negative 15 degree, rotate around the adapter shaft of vertical paper direction.Above-mentioned last hanger 11 is located at the middle part of this main hanging beam 1, above-mentioned a plurality of fixed pulleys 21 are divided into two groups of bottoms of being located at this auxiliary hanging beam 2 respectively, wherein shown in Figure 1 hanging down for each auxiliary hanging beam 2 bottom is provided with the situation of two fixed pulleys 21, each this fixed pulley 21 can rotate arbitrarily in 360 degree scopes around S. A., wherein Figure 2 shows that along the section drawing of A-A ' direction among Fig. 1.The lower central of this main hanging beam 1 also is provided with an assembly pulley 12, and this assembly pulley 12 comprises two fixed pulleys that are parallel to each other, and wherein Figure 3 shows that along the section drawing of B-B ' direction among Fig. 1.
On this main hanging beam 1, last hanger, adapter shaft structure and pulley block structure are all fixed with welding manner, and adopt gusset to strengthen, to guarantee to lift by crane safety.In addition, before handling, according to hoisting weight, the size of lifting segmentation and the distribution situation of suspension centre, check is calculated in intensity, distortion to roof beam structure, hanger and each connection structure of hanging beam, and calculate the stress and the shearing force of assisting hanging beam 2 by Finite Element Method, to guarantee to lift by crane safety further.At different suspension centre distribution modes, select the pulley or the assembly pulley suspension steel wire of correct position to lift by crane, because the direction of fixed pulley 21 can be rotated arbitrarily by 360 degree, so can avoid owing to segmentation suspension centre and the inconsistent steel rope wrapping phenomena that causes of pulley direction.In addition, when lifting is subjected to force unbalance, can also be by adjusting the angle of auxiliary hanging beam 2, to keep the lifting balance preferably, particularly, for example, when using outermost two fixed pulleys in two ends to lift by crane, the inner of two auxiliary hanging beams can be rotated up 15 degree, to guarantee to lift by crane safety.
In sum, the rotary row of hanging of the present utility model has reduced the goods and materials that handling consumed, and has reduced working strength of workers, has improved production efficiency, has shortened the manufacturing cycle, and makes whole handling safe and reliable.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only are casehistorys, under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
