Abstract

The device is specially designed to facilitate the collapsing of towers (4) in movable structures that are frequently assembled and dismantled, such as, for example, in the field of the staging of events. The invention consists in establishing, on the tower (4), a fixed, lower base (2) of scant height, which is securely connected to the general structure (1) on which the tower (4) is to be raised, whilst the remaining, principal sector of said tower (4) is connected to the base (2) via a hinging shaft (3), there being established, between the principal sector (4) of the tower and the fixed structure (1), a connecting rod (6) joined in an articulated manner to both elements, which together with those elements and with the base (2) forms a deformable quadrilateral. A hydraulic or pneumatic piston (7) extends between the connecting rod (6) and the fixed structure (1) such that, in a retraction situation, it generates the collapsing of the principal sector (4) of the tower on the structure (1), whilst in a situation of maximum extension it positions said tower (4) vertically.

Description

Device for collapsing towers in the movable structures

Technical field:

The present invention relates to a kind of specially designed device, the landing of pylon in the movable structures of being convenient in performing active, use (promoting and landing).

The objective of the invention is to make quick, convenient, the simple landing of described pylon, greatly reduce the risk that story takes place in the operating process.

Background technology:

Usually use works out of doors in the activity, these works are assembled together on the ground temporarily, wherein to use very high pylon, separately driving can reach the level of being determined by corresponding pylon height on the pylon, driving can be slided, and these drivings just can be transported the required illuminating equipment of photography activity, pick up camera etc.

The common repeatability of these performing actives is not strong, and in many cases, the three unities is for once performed, and therefore, the landing of pylon has just become regular daily task.

In order to implement the pylon charge and discharge operations, main at present the use manually, general will have ten people at the both sides of pylon dragging and tower, make pylon move to the upright position from level attitude, perhaps opposite, this method is not really reliable and secure, and clearly this needs a lot of artificial participations.

For pylon is moved to level attitude from the upright position, also use the motor motor of described driving (promptly be used for move) of pylon sometimes and by the trapezoidal device pylon that lands, this trapezoidal device can cause unacceptable security risk.

Also can be with small-sized fork truck by rope, by manually dragging the pylon that lands, this method is dangerous equally, because described rope often slides, even fractures.

Sometimes come with hoisting crane, catch on the top of pylon with suspension hook and come the landing pylon, but because of investing or rent described hoisting crane, this method is obviously too expensive.

Summary of the invention:

Device for collapsing towers proposed by the invention, it is simple in structure, safety, easy operating, in full force and effect, has overcome the defective of above-mentioned all kinds of landing method satisfactorily fully.

For this reason, more specifically say, described device is made up of a kind of landing parts, these parts with the form of pipe link with hinging manner, general basic structure thing (tower base is fixed on the works) and described pylon movable part (being the main portion of described pylon) are coupled together, and the pylon main portion is connected on the described pedestal with folding mode, like this, the pedestal assembled portion of pylon and General Construction thing, the movable part of pylon and pipe link have just formed a variable quadrangle, make the movable part of pylon be rendered as two kinds of final positions, i.e. level or landing place, another kind of upright position or use location.

For with described pylon from an evolution to another kind of position, between the centre portion of described pipe link and General Construction thing, be provided with a plunger, the maximum collapse position of plunger is corresponding to the level or the landing place of pylon movable part, and the maximum extension position of plunger is corresponding to the upright position of pylon movable part.

Described plunger is preferably fluid pressure type, this device has one (to use common power line voltage by electro-motor, be the rated voltage of 220V alternating current) force lift that drives, but described plunger obviously can be replaced (will directly be driven by electro-motor at the screw rod described in this system) by " screw rod " prolongation system, thereby makes the selection possibility of pipe link or folding means bevelled mechanism of action in fact unrestricted for being responsible for.

Description of drawings

In order to replenish described explanation, and helping according to one of them embodiment function of the present invention is had better understanding, enclose the component part of a cover accompanying drawing as described explanation, below is the introduction that illustrates with non-limiting feature:

Fig. 1 has shown the side schematic view of a movable structures and a pylon, and pylon is horizontal under the assistance of a kind of launching appliance of the present invention.

Similar among the view that Fig. 2 shows and Fig. 1 is the centre that pylon is in the improvement stage.

Fig. 3 has shown another scheme drawing that is similar to Fig. 1 and Fig. 2, and just pylon is vertical fully.

Fig. 4 has shown the transparent view of one of pylon of the operating position that mediates among the actual side of works part and Fig. 2.

The specific embodiment:

General movable structures, promptly be numbered (1) in the accompanying drawings, a kind of works that can be landed and transport, when carrying out outdoor performance or other activities, be assembled, form (for example) rectangular frame, as shown in Figure 4, the permanent seat (2) of pylon is set on one of rectangle or each summit, this pedestal is fixed on the works (1), pedestal (2) is in height outstanding than works (1), and moving or landing part (4) by a hinge (3) connection pylon, move or land and partly end on the crosspiece (5) with its movable upper end usually, belt wheel or gear ring drive belt conveyor under the driving of the electro-motor of lower or chain is done translatory movement, lifting or landing can be used for the workplatform of different component or the driving of support platform, thereby make it be installed in the height that pylon is determined.

According to above-mentioned basic conventional confguration, and according to device of the present invention, between the movable part (4) of General Construction thing (1) and pylon, be provided with a pipe link or landing parts (6), these parts are connected to two coupled parts with hinging manner, as shown in Figures 1 to 3, just formed a variable parallelogram, two limits wherein, promptly by General Construction thing (1) and two corresponding or definite limits of permanent seat (2), be maintained fixed, and can shift one's position in two other limit, particularly, they can become position shown in Figure 3 from evolution shown in Figure 1 with its degree of dip, correspond respectively to landing or level attitude and its upright position of the movable part (4) of pylon.

For comfortable, safely and conveniently realize this position conversion of movable part (4), between the centre portion of pipe link (6) and General Construction thing (1), be provided with a plunger (7), it determines the maximum inclining position of pipe link (6) when plunger is in the maximum collapse position, determine the level attitude of pylon movable part (4), shown in figure (1) thereupon; And at the plunger overtime, it causes pipe link (6) to be inclined upwardly, pylon movable part (4) is also parallel to be inclined upwardly, as shown in Figure 2, reach the limit of position (certain corresponding usually) up to pipe link with the maximum extension position of described plunger (7), the degree of dip of pipe link this moment (6) has surpassed upright position and reversal dip, and wherein the movable part of pylon (4) presents perfect upright position as the prolongation of its pedestal (2), as shown in Figure 3.

Must should be mentioned that at last, when movable structures is in use or transportation, pipe link or landing parts (6) and plunger (7) must remove, for this reason, General Construction thing and pylon must possess the quick connection the/disengagement gear that is used for pipe link and plunger, and these members also will have quick connection/disengagement gear each other.Like this, a launching appliance just can be used on a plurality of pylons that constitute a works equally.
