Abstract
Disclosed is a movable cover board of a stage. According to a table surface component (1) of the cover board, four cover board supporting wheels (2) are supported on slope blocks (3). The four slope blocks (3) are respectively installed on a trolley table beam (7) which is provided with four trolley idler wheels (9). One end of an electric push rod (4) is fixed to a lifting platform frame, and the other end of the electric push rod (4) is fixed to the trolley table beam (7). The trolley table beam (7), the slope blocks (3) and the trolley idler wheels (9) are combined into a whole; the trolley table beam (7), the slope blocks (3), the trolley idler wheels (9) and a movable cover board body can move on a trolley guide rail (8) under the drive of the electric push rod (4).
Description
Technical field
The utility model relates to the special purpose device of stage machinery.
Background technology
For performance sites such as large-scale performing art venue of modern times and multi function halls, miscellaneous stage machinery all is installed, to adapt to the performance requirement of various songs, reach performing effect changeable.
At present, the hole of 1～several 1m * 1m left and right size usually all is set on the stage table top of the upper strata of duoble-layer table top elevating stage, but sometimes at individual layer elevating stage table top or there is on the fixedly stage table top in platform storehouse also reserving hole, utilize lift cart to carry personnel, stage property etc., as magic show, to increase the special effects of performance.Under normal circumstances, these holes cover, to form complete stage table top.In prior art, mostly take artificial manual electricity to drive and control, easily produce error.
Summary of the invention
The purpose of this utility model is to provide a kind ofThe stage removable cover.
The utility model is the stage removable cover, cover plate table top parts 1 are supported on ramp blocks 3 by four cover plate support wheels 2, four ramp blocks 3 are contained in respectively on dolly platform beam 7, dolly platform beam 7 is equipped with four trolley idler wheels 9, one end of electric pushrod 4 is fixed on the elevating stage support body, and the other end is fixed on dolly platform beam 7, and dolly platform beam 7, ramp blocks 3, trolley idler wheels 9 form a whole, together with the removable cover on it, under the driving of electric pushrod 4, can on vehicle guide 8, move.
Usefulness of the present utility model is: relatively simple for structure, operate steadily, and positioning precision is high.With respect to the lower turning type cover plate of current use, security reliability improves greatly.By stage machinery operating desk centralized Control, the stroke of cover plate is controlled by being contained in travel switch on electric pushrod, puts in place automatically to stop afterwards.
The accompanying drawing explanation
Fig. 1 is the structure chart of stage removable cover while sealing hole, and Fig. 2 is the structure chart of hole while opening, the top view that Fig. 3 is Fig. 1.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows,The utility model is the stage removable cover, cover plate table top parts 1 are supported on ramp blocks 3 by four cover plate support wheels 2, four ramp blocks 3 are contained in respectively on dolly platform beam 7, dolly platform beam 7 is equipped with four trolley idler wheels 9, one end of electric pushrod 4 is fixed on the elevating stage support body, and the other end is fixed on dolly platform beam 7, and dolly platform beam 7, ramp blocks 3, trolley idler wheels 9 form a whole, together with the removable cover on it, under the driving of electric pushrod 4, can on vehicle guide 8, move.
As shown in Figure 1 and Figure 2,Cover plate table top parts 1 move to position under hole guide wheel 5, the cover plate block 6 that can stop cover plate table top parts 1 to continue to move ahead and start vertical ascending motion are installed.All have on the wheel of cover plate support wheel 2, trolley idler wheels 9 and can make removable cover and the Orbiting gathering sill of dolly platform beam.
As shown in Figure 1, Figure 2, Figure 3 shows, of the present utility modelThe course of work is: in the time of need to opening hole according to the performance requirement, and electric pushrod 4 energisings, the push rod retraction, drive dolly platform beam 7, ramp blocks 3 etc. and move right.Now, cover plate table top parts 1 descend along the inclined-plane of ramp blocks 3 under acting in hole, ramp blocks 3, guide wheel 5, cover plate block 6.Due to the effect that guide wheel 5, cover plate block 6 are arranged, cover plate is vertical decline, there is no horizontal movement.
As shown in Figure 2, when cover plate table top parts 1 continue to descend until cover plate support wheel 2 while dropping to ramp blocks 3 left end arc surface, cover plate table top parts 1 stop descending and being located by the arc surface of ramp blocks 3, now, the upper surface of cover plate table top parts is lower than the appear on the stage soffit of beam of elevating stage, start horizontal movement to the right under the drive of dolly, until cover plate table top parts 1 leave the hole mouth fully, the electric pushrod outage is out of service.
As shown in Figure 1, when needs cover hole, electric pushrod 4 energising, push rod stretches out, drive dolly platform beam 7, ramp blocks 3 and on cover plate table top parts 1 to left movement.In the time of directly over cover plate table top parts are moved horizontally to hole, cover plate block 6 contacts with guide wheel 5, guide wheel 5 stops cover plate table top parts 1 to continue to move to left, but under the jacking of ramp blocks 3 vertical lifting, until cover plate table top parts 1 are concordant with the elevating stage table top, now, the elevating stage table top is restored to monoblock elevating stage table top.
Claims (3)
1. stage removable cover, it is characterized in that cover plate table top parts (1) are supported on ramp blocks (3) by four cover plate support wheels (2), four ramp blocks (3) are contained in respectively on dolly platform beam (7), dolly platform beam (7) is equipped with four trolley idler wheels (9), one end of electric pushrod (4) is fixed on the elevating stage support body, the other end is fixed on dolly platform beam (7), dolly platform beam (7), ramp blocks (3), trolley idler wheels (9) forms a whole, together with the removable cover on it, can be upper mobile at vehicle guide (8) under the driving of electric pushrod (4).
