Abstract
The utility model discloses a swinging strut type pole head, which comprises a square base and an upright post vertically arranged at the center of the base. A hoist boom and a wire puling rack are sequentially installed on the upright post from top to bottom, and the hoist boom is ratably connected with the upright post. The swinging strut type pole head has the advantages of reasonable design and simple structure, adapts to the tower construction process of external wire pulling and internal hanging, ensures the safety of construction, improves operating efficiency, and creates good economic social benefits.
Description
Technical field
The utility model belongs to the weight-lifting equipment technical field, is specifically related to a kind of swinging strut formula pole head.
Background technology
At present, all there is following problem in domestic most of pole manufacturer to the design of pole head aspect the large-tonnage lifting.At first, lifting large-tonnage member polyspast is in a side, and pole head moment of flexure is very big, and the punching bolt resistance to shear of conventional pole head is difficult to meet the demands; Secondly, most of pole manufacturer still designs according to original interior backguy inner suspended holding pole mode, and the pole external cable is below the Heave Here, and hanging piece and external cable are collided in the time of certainly will causing single leg to lift main material like this, are unfavorable for constructing operation; When having lifted the hanging piece of six direction wherein at last, tackling system is difficult to walk around two hanging pieces that backguy goes to lift other symmetry above external cable, so just must hang two groups of tackling systems in addition and go lifting, not only reduce work efficiency, also increase labour intensity.
The utility model content
The utility model is in order to solve weak point of the prior art, and a kind of simple in structure, safety good, operating efficiency is high swinging strut formula pole head is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: swinging strut formula pole head, comprise plinth, and base central authorities vertically are provided with column, arm of derrick and wire pulling rack are installed on the described column from top to bottom successively, and arm of derrick and column are rotationally connected.
Described wire pulling rack and column are bolted to connection.
Described wire pulling rack comprises the cylindrical shell that is connected with column, at least evenly be provided with three pulling string arms on the cylindrical shell excircle, each pulling string arm top all is positioned at same plane, outer end and all offers the backguy hole, and adjacent pulling string arm is connected to each other by the pipe link that its outer end is provided with.
Described arm of derrick comprises the sleeve pipe that is set on the column and is rotationally connected with it, and rotational symmetry is provided with two suspension rods on the sleeve pipe excircle.
Described column is the hollow cylinder structure.
Adopt said structure, column replaces the punching bolt, and anti-shear ability is strengthened; Arm of derrick is arranged on wire pulling rack below, and promptly the pole external cable is above the Heave Here, and hanging piece and external cable are collided when so just having avoided single leg to lift main material, are beneficial to constructing operation; Wire pulling rack and column are bolted to connection, and can guarantee pole single-piece stability; This structure of wire pulling rack, arm of derrick and column, reasonable in design, saving in material; The utility model is reasonable in design, simple in structure, adapted to external cable inner suspension group tower construction technology, guaranteed safety of construction, improved operating efficiency, created good economic benefit and social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, swinging strut formula pole head of the present utility model comprises plinth 1, and base 1 central authorities vertically are provided with column 2, and column 2 is the hollow cylinder structure, and arm of derrick and wire pulling rack are installed on the column 2 from top to bottom successively.Wire pulling rack comprises and column 2 bolted cylindrical shells 3, evenly be provided with four pulling string arms 4 on cylindrical shell 3 excircles, each pulling string arm 4 top all is positioned at same plane, outer end and all offers backguy hole 5, and adjacent pulling string arm 4 is connected to each other by the pipe link 6 that its outer end is provided with.Arm of derrick comprises the sleeve pipe 7 that is set on the column 2 and is rotationally connected with it, and rotational symmetry is provided with two suspension rods 8 on sleeve pipe 7 excircles, and the suspension rod outer end is equipped with lifting eye 9.
When work is used, the pole head is installed in the pole top, the backguy rope is captiveed joint with backguy hole 5, and the lifting rope is captiveed joint with lifting eye 9, then pole is erected, and four backguy ropes are provided with pole stable.Because arm of derrick is below wire pulling rack, promptly lift by crane rope below the backguy rope, in the time of the lifting object, just to have avoided like this and the colliding of backguy rope, arm of derrick can 360 ° of rotations, so just can carry out lifting construction easily and quickly.
