Abstract
A hinge type pitching steel structure tower consists of a tower support bar, a tower tie rod, a tower lower body, a counterweight arm tie rod and a cantilever beam tie rod. The upper end of the tower support bar is provided with three upper hinge points which are respectively hinged with the counterweight arm tie rod, the cantilever beam tie rod and the tower tie rod with lines of action of force joining at the top of the tower support bar, and the lower end of the tower support bar is provided with a lower hinge point which is hinged with the tower lower body; the upper end of the tower tie rod is hinged with the tower support bar, and the lower end of the tower tie rod is hinged with the tower lower body. The utility model has the advantages of removing additional bending moment on the support bar and a main tie rod, reducing local stress status, bringing about simple and rational stress for convenient analysis, removing a plurality of positions needing coupling through high strength bolts, and reducing the work load of inplant preassembly and field erection with simple manufacture, and convenient erection and maintenance.
Description
Technical field
The utility model belongs to the large-scale handling equipment field of high efficiency continuous working, relates in particular to the pylon of the bucket-wheel stacker reclaimer in loose unpacked material yard.
Background technology
Bucket-wheel stacker reclaimer be at the harbour, the large-scale handling equipment of a kind of high efficiency continuous working of large and medium-sized thermal powerplant and industry loose unpacked material yard widespread uses such as metallurgy, coking, be used to load and transport various ores, coal, sandstone, coke, chemical etc.The pylon of existing bucket-wheel stacker reclaimer is an integral solder formula pitching steel structure pylon.The deficiency of this integral solder formula pitching steel structure pylon is: owing to be the structure of integral solder formula, its stressing conditions complexity all has additional bending moment on strut bar, the pull bar, and force analysis is difficult in the design and installation process, and easily causes local stress big; Since be the structure of integral solder formula, bulky, for ease of transportation, can only during on-site installation, adopt high strength bolt that each section linked up its sectional making.Like this, the whole erection process needs through preassembly in factory, two processes of on-site installation, and work capacity is bigger.
Summary of the invention
The purpose of this utility model provides a kind of radial type steel structure pylon, eliminates the additional bending moment of bucket-wheel stacker reclaimer pylon strut bar, pull bar, reduces local stress, reduces installation workload.
Technical solution of the present utility model is: radial type pitching steel structure pylon, form by pylon strut bar, pylon pull bar, pylon lower body, weight arm pull bar, cantilever beam pull bar weight arm and cantilever beam, weight arm and cantilever beam are connected on the pylon lower body, and its structure is:
Described pylon strut bar is pure pressure type two power bars, the pylon post upper is provided with upper link point, hinged with weight arm pull bar, cantilever beam pull bar, pylon pull bar respectively, weight arm pull bar, cantilever beam pull bar, the hinged back of pylon pull bar line of action of force intersect at the top end of pylon strut bar, described pylon strut bar lower end is provided with lower link point, and is hinged with the pylon lower body; Described pylon pull bar is single pull-type two power bars, and pylon pull bar upper end is hinged with the upper link point of the upper end of pylon strut bar, and lower end and pylon lower body are hinged.
Radial type pitching steel structure pylon described in the utility model, its structure is that the upper link point of described pylon post upper is provided with three places, lay respectively on opposed two surfaces of pylon strut bar, a hinge-point is set on the surface, two hinge-points are set on another surface, two hinge-points distribute up and down, and the superincumbent hinge-point that distributes is corresponding with the hinge-point on opposite.
Radial type pitching steel structure pylon described in the utility model, its structure is that described pylon pull bar forms by two, two pylon pull bars are splayed to be supported, draw in the upper end, the lower end separately, the upper end of every pull bar is hinged with the upper link point of the upper end of pylon strut bar respectively, and the lower end is hinged with the pylon lower body respectively.
Radial type pitching steel structure pylon described in the utility model, its structure are that the articulated form of described each hinge-point is with pivotal axis two articulation pieces to be connected.
Advantage of the present utility model and effect are:
1, this radial type pylon, make strut bar become single depression bar, make main tie become simplex pull rod, eliminated the additional bending moment on strut bar, the main tie, the stressing conditions that makes strut bar and pull bar is advantages of simple more, reduced the local stress state, be convenient to design analysis, thereby made steel structure be able to more efficient use.
2, this radial type pylon has been removed many places and need have been reduced preassembly in factory, on-site installation work amount with the place of high strength bolt connection, has reduced cost of installation.
3, make simply, be convenient to I﹠M.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.Pylon strut bar 2 is rigidity poles, its upper end is provided with three place's upper link points 5, hinged with weight arm pull bar 6, cantilever beam pull bar 7, pylon pull bar 3 respectively, the line of action of force junction that makes weight arm pull bar 6, cantilever beam pull bar 7, pylon pull bar 3 after hinged is 1: 8, pylon strut bar 2 lower ends are provided with lower link point 9, and are hinged with pylon lower body 4.Pylon pull bar 2 is formed by two, becomes splayed to support, and draw in the upper end, and the lower end separates, and the upper end of every bar is hinged respectively at the last interface point on the strut bar, and lower end and pylon lower body 4 are hinged.The stressing conditions of present embodiment is analyzed as follows: because every pull bar all is hinged with strut bar and pylon lower body respectively, so every pull bar all becomes two power bars, pure simplex pull rod.6 pairs of strut bar 2 pulling force of weight arm pull bar and cantilever beam pull bar 7,3 pairs of strut bar 2 pulling force of pylon pull bar are balance in the horizontal direction, 2 pressure that are subjected on the vertical direction of strut bar, the power that acts on strut bar 2 upper ends balances each other in the power that vertical direction and pylon lower body 4 act on strut bar 2 lower ends, and pylon strut bar 2 becomes pure depression bar.Thereby pylon is a rock-steady structure.
