Abstract

The invention is a stick pyramid, in particular for stalling mast sections of power transmission towers in crane flight. An existing from several Kantenstaeben floor pyramid in Fuszbereich about in a Hülse can be inserted, which can be connected via variably trainee bulkhead and Anschluszbleche to the corner post of the Fuszkonstruktion or the stock part.

Description

Field of application of the invention

The invention relates to a stick pyramid, in particular for the stoppage of mast sections of power transmission towers in crane flight.

Characteristic of the known state of the art For unmanned stoppage of mast sections an arrangement (SU-PS 633799) was proposed in the ropes on a Center support were clamped pyramid-like. The mast section to be halted is crane-hoisted over this pile pyramid

lowered, so that a self-centering of this Stcckteiles occurs.

Disadvantage of this arrangement is the restriction to relatively loose parts of the floor. Another known device (US-A-4189892) for stopping mast sections with automatic alignment of the Part of the pile consists of four obliquely inwardly and upwardly projecting short edge bars, which are at the corner stems of the lower Mast sections are appropriate. The disadvantage here is that the leadership of the stock part is guaranteed only in the final phase of the stocking process. It is finally a mounting device (EP-PS 0054508) has become known, the bent edge bars a

form pyramid-shaped guide body. This guide body sits up as a cylindrical centering with

Hanger continued. When lowering the attached to the crane helicopter stock part above the floor pyramid learns the Stake first a vertical centering over the cylindrical part of the floor pyramid, which on further lowering over

the pyramid-shaped part in an increased rotational centering passes.

Disadvantage of the mounting device described is that each mast section with a separate, fixed Guide body must be provided. Object of the invention

It is an object of the invention to reduce the stocking charges for stick pyramids when assembling various types and sizes of mats.

Explanation of the essence of the invention

The invention has for its object to re-form a stick pyramid, so that the most essential components for different applications are reusable.

According to the invention composed of a plurality of bent edge bars stick pyramid with the corner handles of Kippstoßes or those of the previously mast section previously connected so connectable that the foot portions of the edge bars in sleeves inserted and locked there by means of pins there, the sleeves according to the mast design adapted bulkhead and connection plates connected to the corner stems.

Ausführungsbüspiel

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawing shows

Fig. 1: the unmanned stag in crane flight 2 shows the schematic representation of the guide means on the tilting joint 3 shows the side view of an edge bar with guide sleeves on the tilting joint Fig. 4: the side view of an edge bar with sleeve on the butt joint 5 shows the plan view of Fig.4.

As shown in FIG. 1, a fattening section prepared for faltering is to be placed on the tilting joint by means of a helicopter 1. For this purpose, the stick part was provided at the lower end with a guide frame 6 and catch bolt 5. At Kippstoß in the exemplary embodiment known per se safety gears 3 are arranged, which serve for guiding and catching the catch part arranged on the pole 5.

Because of the generally larger dimensions of the mast in the foot area, the canopy is on the mast construction

arranged in dissolved form, d. H. the edge bars 7 of the floor pyramid are not combined in the upper area.

In the upper part of the edge bars 7 of the floor pyramid are bent to the stock part when lowering an increasingly

give closer guidance.

At the for mounting the Kippstoßknotenbleets provided holes a stop plate 12 is screwed,

to which a sleeve 14 connects via an inter-welded partition plate 13. In these sleeves 14, the edge bars 7 of the floor pyramid are inserted and locked by means of a plug 8. The falling through of the edge bars 7 prevents each welded under the sleeves 14 end plate 15. The bulkhead plates 13 on the butt joint are also with a

Stabilization frame 4 connected.

To support the arranged above the tipping thrust resolved guide pyramid 7 sleeve-like head pieces 9 were attached to the edge bars, which are rigidly connected to supporting on the mast foundation supports 10.

As also shown in FIG. 1, the cane part is formed on the upper butt joint with one of a plurality of edge bars 7 Stick pyramid provided. The upper end of the floor pyramid forms an unspecified in the exemplary embodiment Stiffening construction. At the corner posts 11 of the floor part are in the area of the upper floor push - analogous to Kippstoßbereich - more automatic

3 arresting safety gears for the next stick tet! arranged.

The edge bars 2 of the floor joint associated with a stick pyramid are also about sleeves 15, bulkheads 13 and Connecting plates 15 screwed to the Eckstielprofilen 11. In the following, the operation of the device will be described. The advantage of the device described is, in particular, that in many applications the same edge bars 2,7

for stick pyramids for different applications, such as different hole brothers on tipping and stick joints, different mast types and dimensions and different corner angle thicknesses to use. Essential elements for

Adaptation and fixation of the stick pyramids are the sleeves 14, bulkhead plates 13 of different dimensions as well Connecting plates 15 with different hole patterns. To stiffen the first pole segment above the tipping thrust this is from the lifting screw: 1 on the here dissolved Lowered pyramid. An arranged below the floor part guide frame 6 wins when sliding onto the

Edge bars 7 increasingly guide until the catch pin 5 of the funnel-like safety gears 3 in the

Guided end position and there automatically locked in a known manner. The cane pyramid can now easily disassembled

and be used again at another mast location.

In the same way, the sticking process takes place at the butt joint.

Claims (1)

1. floor pyramid, in particular for unmanned stagnation of the mast sections for high-voltage power poles, with a pyramid-shaped guide arrangement formed of several edge bars, characterized in that the edge bars (2; 7) in sleeves (14) are pluggable and lockable, wherein the sleeves (14) via variably trainees bulkhead plates (13) and stop plates (12) with the Eckstielen (11) are twistable.
