Description

Technical Field

[0001] The present invention relates to the field of performance equipment, and in particular to a performance stage with a composite transformation function. Background Art

[0002] In order to meet the diversification of performances, existing stages usually need to have lifting and rotating functions. When performers are performing on the stage, they are in high spirits and usually look directly at the audience seats, so it is not easy to pay attention to the situation under their feet. When the stage rises, although the performers know that the stage is in the rising state and will not move, they still make some small-scale moving actions to increase the performance appreciation. However, during the small-scale movement process of the performers, it is difficult to see the edge of the stage clearly due to the stage lighting, and there is a risk of moving too far towards the edge of the rising stage and falling off the stage. Moreover, the performers frequently lower their heads to check the safe area of the stage, which greatly affects the performance appreciation. Summary of the Invention

[0003] In order to overcome the shortcomings that when performers move in a small range on a rising stage, it is difficult to see the edge of the stage clearly, there is a risk of moving too far towards the edge of the rising stage and easily falling off the stage, the present invention provides a performance stage with a composite transformation function.

[0004] The technical solution is as follows: A performance stage with a composite transformation function includes support columns, an installation frame, an electric lifting platform, and a rotation drive assembly; a plurality of support columns are arranged in a rectangular array; four sliding rods are slidably connected in each support column; a connecting bolt is connected to the top of each sliding rod; a fixing frame is inserted between every two adjacent support columns; an installation frame is fixedly connected by connecting bolts between every four support columns; an installation plate is fixedly connected inside the installation frame; a rotating table is rotatably connected to the middle of the installation plate; an electric lifting platform is arranged below the installation frame; a rotation drive assembly is connected to the lower side of the rotating table; it further includes a lifting frame, a support frame, a connecting rod, a telescopic rod, a stepping block, and an emergency stop controller; a lifting frame is slidably connected between the installation frame and the installation plate; a support frame is fixedly connected to the lower side of the lifting frame; the support frame is composed of a support frame body and support feet; the support frame body contacts the electric lifting platform; a number of connecting rods are distributed in a rectangular shape on the lifting frame; a telescopic rod is rotatably connected to each connecting rod; all the upper sides of the connecting rods on the same side of the lifting frame are rotatably connected to a stepping block together; each stepping block is rotatably connected to the telescopic end of the corresponding telescopic rod; a main air pipe is installed in each stepping block; the connection port of the main air pipe is located on the lower side of the stepping block; the connection port is connected to an external air pump through a hose, and a pressure sensor is arranged on the stepping block; each main air pipe communicates with a number of branch air pipes; the outlets of the branch air pipes face away from the center of the installation frame; an emergency stop controller for stopping the operation of the rotation drive assembly is slidably connected to the installation plate.

[0005] Preferably, the rotary drive assembly comprises a motor, a spur gear and a ring gear; the motor is fixedly connected to the support frame via a connecting frame; the spur gear is fixedly connected to the output end of the motor; the ring gear is fixedly connected to the rotating platform; the ring gear and the spur gear are meshed, and the thickness of the spur gear is smaller than the thickness of the ring gear.

[0006] Preferably, the emergency stop controller consists of a mounting ring, an elastic part, a connecting column and a ball; the mounting ring is slidably connected to the mounting plate; a number of elastic parts are connected to the mounting ring in a ring-shaped distribution; each elastic part is connected to a connecting column; the connecting column is slidably connected to the mounting ring; a ball is installed on the top of each connecting column; and all connecting columns are connected to additional pressure sensors.

[0007] Preferably, each treading block surface is provided with a plurality of protrusions.

[0008] Preferably, the edges of adjacent treading blocks are arranged to fit together in an arc shape.

[0009] Preferably, the surfaces of the mounting frame, mounting plate and rotating table are all treated with anti-slip treatment.

[0010] Preferably, a protective component is also included, which includes a protective cloth and a fixing ring; the protective cloth is rolled up between two adjacent supporting feet on the corresponding lifting frame through a torsion spring roller; the free end of the protective cloth is connected to two fixing buckles; and a plurality of two fixing rings are fixed to the bottom of each supporting column.

[0011] Preferably, the protective cloth is made of nylon.

[0012] Preferably, the torsion spring roller for rolling up the protective cloth is movably fixed to the supporting foot.

[0013] Preferably, the fixing buckle is connected to the protective cloth via an elastic band, so that the position of the fixing buckle can be adjusted to connect with the fixing ring.

[0014] The beneficial effect is that: the present invention realizes that when the stage is raised, the performer gradually approaches the stepping block while exploring the way with his feet, and when the foot steps on the stepping block, the performer clearly feels the strange feeling brought by the raised stepping block, thereby reminding the performer that he is close to the edge of the stage surface and cannot move further. Therefore, without blocking the performer's body and without the performer having to lower his head to observe his position, the performer is reminded to stop moving at the current position to avoid falling from the raised stage.

[0015] Air is blown away from the center of the stage through the bronchial tubes, forming a horizontal outward airflow around the stage, blowing the performer's hanging skirt away from the center of the stage, so that the skirt expands in a plane direction, and then after the stage descends and fits with the adjacent stage, the skirt will fall on the upper surface of the adjacent stage, avoiding the skirt being sandwiched between the descending stage and the adjacent stage;

[0016] When using the rotation function, the performer's feet extend beyond the rotating platform and step on both the rotating platform and the mounting plate. The connecting column will be stepped on, and the pressure sensor will receive a pressure signal, controlling the rotation drive assembly to stop working and the rotating platform to stop driving the performer to rotate. This can prevent the rotating platform from driving the performer's feet to move, while the stationary mounting plate will generate resistance to the performer's feet, which is likely to cause the performer to lose balance and fall.

[0017] The rising stage is fully surrounded by a protective cloth. When a performer on the non-rising stage stretches, their limbs will be blocked by the protective cloth and cannot reach under the rising stage, thus avoiding injury. At the same time, the taut protective cloth can prevent the performer on the non-rising stage from falling under the rising stage and having an accident. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1

[0034] As Figures 1 - 12 shown, a performance stage with a composite transformation function includes a support column 1, a mounting frame 2, an electric lifting platform 001 and a rotation driving assembly; a plurality of support columns 1 are arranged in a rectangular array; four slide bars 101 are slidably connected in each support column 1; a connecting bolt 102 is connected to the top of each slide bar 101; a fixing bracket 103 is inserted between every two adjacent support columns 1, and the adjacent two support columns 1 are connected and fixed by the fixing bracket 103; a mounting frame 2 is connected by connecting bolts 102 between every four support columns 1; a mounting plate 201 is fixedly connected in the mounting frame 2; a rotating table 202 is rotatably connected to the middle of the mounting plate 201; an electric lifting platform 001 is arranged below the mounting frame 2; a rotation driving assembly is connected to the lower side of the rotating table 202;

[0035] It also includes a lifting frame 3, a support frame 4, a connecting rod 5, a telescopic rod 6, a stepping block 7 and an emergency stop controller 8; a lifting frame 3 is slidably connected between the installation frame 2 and the installation plate 201; a support frame 4 is fixedly connected to the lower side of the lifting frame 3; the support frame 4 is composed of a support frame 401 and support feet 402; the support frame 401 contacts the electric lifting platform 001; a number of connecting rods 5 are distributed in a rectangular shape on the upper side of the lifting frame 3; a telescopic rod 6 is rotatably connected to each connecting rod 5; all the upper sides of the connecting rods 5 on the same side of the lifting frame 3 are rotatably connected to a stepping block 7 together; each stepping block 7 is rotatably connected to the telescopic end of the corresponding telescopic rod 6; a main air pipe 701 is installed in each stepping block 7; the connection port 702 of the main air pipe 701 is located on the lower side of the stepping block 7; the connection port 702 is connected to an external air pump through a hose, and a pressure sensor is provided on the stepping block 7; the external air pump is controlled to work by the stepping on the stepping block 7 to trigger the pressure sensor; each main air pipe 701 is communicated with a number of bronchial tubes 703; the outlets of the bronchial tubes 703 face away from the center of the installation frame 2; an emergency stop controller 8 is slidably connected to the installation plate 201.

[0036] The rotary drive assembly includes a motor 002, a spur gear 003 and a gear ring 004; the motor 002 is bolted to the support frame 401 through a connecting frame; the output end of the motor 002 is fixedly connected with a spur gear 003; the gear ring 004 is fixedly connected to the lower side of the rotary table 202; the gear ring 004 meshes with the spur gear 003, and the thickness of the spur gear 003 is less than the thickness of the gear ring 004.

[0037] The emergency stop controller 8 is composed of an installation ring 801, an elastic member 802, a connecting column 803 and a ball 804; the installation ring 801 is slidably connected to the installation plate 201; a number of elastic members 802 are annularly distributed and connected to the installation ring 801; the elastic members 802 are springs; each elastic member 802 is connected with a connecting column 803; the connecting column 803 is slidably connected to the installation ring 801; a ball 804 is installed on the top of each connecting column 803; all the connecting columns 803 are connected with other pressure sensors, and when the connecting column 803 is pressed, the pressure sensor sends a signal to control the rotary drive assembly to stop working.

[0038] Each surface of the stepping block 7 is provided with a protrusion; to increase the touch feeling when the performer steps on the stepping block 7.

[0039] The edges of adjacent stepping blocks 7 are arranged in an arc-shaped fit; to avoid affecting the tilting movement between adjacent stepping blocks 7 and at the same time ensure the fit tightness between adjacent stepping blocks 7.

[0040] The surfaces of the installation frame 2, the installation plate 201 and the rotary table 202 are all treated with anti-slip; thus, there is no need to lay a carpet for anti-slip, reducing the workload of stage arrangement.

[0041] The bottom of the support column 1 is provided with an anti-slip pad; this prevents the support column 1 from slipping when it is placed on a smooth ground.

[0042] The stage surface of the present invention is composed of a mounting frame 2, a mounting plate 201, and a rotating table 202; when installing the present invention, the four support columns 1 are arranged in a rectangular combination, and the adjacent support columns 1 are fixed by four fixing frames 103, as Figure 3 shown. Then, the worker installs the mounting frame 2 on the corresponding connecting bolts 102 of the four support columns 1 through bolts (the corresponding connecting bolts 102 refer to the connecting bolts 102 close to the center of the rectangle formed by the four support columns 1) to fixedly connect the stage surface with the support columns 1 to form a single stage; as Figure 1 shown. The present invention can set multiple groups of support columns 1 and multiple mounting frames 2 to be connected to each other, thereby forming a large stage, adapting to performances of different scales, and increasing practicality; when used as a large stage in combination, according to actual usage requirements, electric lifting platforms 001, motors 002 and other parts are selectively arranged below the single stage that needs to be lifted and rotated to drive, reducing the layout time and saving equipment costs; after installation, connect the electric components to the power supply for use.

[0043] When the lifting function is needed, the electric lifting platform 001 provided under the mounting frame 2 that needs to be lifted is controlled to rise. The upper surface of the electric lifting platform 001 contacts the lower surfaces of the mounting frame 2, the mounting plate 201, and the rotating table 202, lifting the stage surface composed of the mounting frame 2, the mounting plate 201, and the rotating table 202, thereby realizing the rising operation. During the rising process of the stage surface, since the four corners of the mounting frame 2 are fixedly connected to the corresponding sliding rod 101 through the connecting bolt 102, the corresponding sliding rod 101 is driven to extend upward out of the support column 1, maintaining the connection between the stage surface and the support column 1 and ensuring stability.

[0044] After the stage rises, although the performers know that the stage is in the rising state and will not move, they still make some small-range moving actions, increasing the performance's viewing pleasure. However, during the small-range movement of the performers, due to the stage lighting, it is difficult to see the location of the stage edge, there is a risk of moving too close to the edge of the rising stage and falling off the stage, and the performers frequently lower their heads to check the safe area of the stage, which greatly affects the performance's viewing pleasure.

[0045] Therefore, a lifting frame 3 is slidably arranged on the mounting frame 2, and a support frame 4 is arranged under the lifting frame 3. Thus, when the corresponding mounting frame 2 needs to rise and the electric lifting platform 001 raises the present invention, the performer stands at the center position of the rotating table 202, the electric lifting platform 001 is started to rise, and the electric lifting platform 001 first contacts the bottom surface of the support frame 401, pushing the support frame 4 to rise, as Figure 6As shown, each support leg 402 of the support frame 4 pushes the lifting frame 3 upward. At this time, due to the self-weight of the installation frame 2 plus the frictional resistance between the sliding rod 101 connected thereto and the support column 1, the installation frame 2 first remains stationary, and the lifting frame 3 moves upward relative to the installation frame 2. Until the bottom surface of the lifting frame 3 is flush with the bottom surface of the installation frame 2, since the coverage area of the support leg 402 includes the four corners of the installation frame 2 and the lifting frame 3, the support leg 402 contacts the bottom surface of the installation frame 2 at the same time, and at the same time pushes the installation frame 2 and the lifting frame 3 upward, and the entire stage surface rises. After the bottom surface of the lifting frame 3 is flush with the bottom surface of the installation frame 2, as Figure 7 shown, each stepping block 7 will be slightly higher than the upper surface of the installation frame 2, surrounding the mounting plate 201 and the rotating table 202. When the performer standing at the center of the rotating table 202 makes a small movement, out of instinct, he will first use his feet to explore the way. At this time, if the performer approaches the edge of the stage, he will gradually approach the stepping block 7. When touching or stepping on the stepping block 7, the strange feeling brought by the protruding stepping block 7 can be clearly felt. At the same time, the protrusions provided on the surface of the stepping block 7 further strengthen the tactile feedback to the soles of the performer's feet, thus warning the performer that he has approached the edge of the stage surface and cannot continue to move. Therefore, without blocking the performer's body and without the performer having to look down and observe, which does not affect the performance effect, the stepping block 7 provides a warning function to remind the performer to stop moving at the current position to avoid falling from the raised stage and causing a performance accident.

[0046] When the stage surface needs to be lowered, control the electric lifting platform 001 to contract, driving the supported stage surface to descend. The sliding rod 101 slides downward and resets. The installation frame 2 descends until the four corners contact the top of the support column 1 and then stops descending. At this time, the electric lifting platform 001 continues to descend, driving the lifting frame 3 and the support frame 4 to move downward, so that the upper surface of the stepping block 7 is flush with the upper surface of the installation frame 2, restoring the flatness of the normal stage surface and facilitating the performer to move on the large stage.

[0047] Furthermore, some performers will wear long-sweeping skirts, and the skirt hems will drag on the stage surface. When the performer is lifted by a single stage and approaches the edge of the raised stage, the skirt hems are likely to fall outside the surface of the stage where they are located. When the stage descends and resets, the fallen skirt hems are easily caught between the descending stage and the adjacent stage and cannot be pulled out, affecting the performance. Therefore, when arranging the stage, an external air pump is connected to the connection port 702 through a hose. When the air pump is pressed by stepping on the stepping block 7, the pressure sensor is triggered to work. When the stage is raised, at this time, the stepping block 7 is in a state of protruding from the stage surface. When the performer approaches the edge of the raised stage, the exploring foot will also step on the stepping block 7, thereby triggering the air pump to work. Air is pumped into the main air pipe 701 through the connection port 702 by the connected hose, and then the air is blown out from each bronchial tube 703 in a direction away from the center of the stage. The bronchial tubes 703 are horizontally oriented, and thus a horizontally outward blowing air current is formed around the stage, blowing the fallen skirt hems of the performer in a direction away from the center of the stage where they are located, causing the skirt hems to expand in a planar direction. Then, after the stage where they are located descends and fits with the adjacent stage, the skirt hems will fall on the upper surface of the adjacent stage, preventing the skirt hems from being caught between the descending stage and the adjacent stage. After the stage descends in place, the air pump will stop working.

[0048] When the rotation function is needed, after the performer stands on the rotating platform 202, the motor 002 is controlled to work to drive the spur gear 003 to rotate. The spur gear 003 meshes with the ring gear 004, and then the ring gear 004 drives the rotating platform 202 and the performer on it to rotate, realizing the rotation function.

[0049] When using the rotating function, the performer's small movement may cause his feet to step between the rotating platform 202 and the mounting plate 201. At this time, the rotating rotating platform 202 drives the performer's feet to move, while the stationary mounting plate 201 generates resistance to the performer's feet, which may cause the performer to lose balance and fall. Before using the rotating function, the electric lifting platform 001 is first controlled to rise, and the electric lifting platform 001 pushes the support frame 4 to rise, and the support foot 402 contacts the bottom surface of the mounting ring 801, pushing the emergency stop controller 8 to rise at the same time until the top of the connecting column 803 is slightly higher than the upper surface of the mounting plate 201. When the performer's foot moves slightly beyond the surface of the rotating platform 202 and steps on part of the connecting column 803, the connecting column 803 is compressed downward by the stepping pressure of the elastic member 802, and at the same time, the corresponding pressure sensor on the bottom surface of the mounting ring 801 senses that the connecting column 803 is under pressure, and sends a signal to control the motor 002 to stop working, so that the rotating platform 202 no longer drives the performer to rotate, thereby preventing the performer's feet from exceeding the rotating platform 202 and stepping on the rotating platform 202 and the mounting plate 201, the rotating rotating platform 202 drives the performer's feet to move, and the stationary mounting plate 201 generates resistance to the performer's feet, which can easily cause the performer to lose balance and fall down; at the same time, the ball bearings 804 on the connecting column 803 roll to reduce the instantaneous friction resistance of the performer's feet on the connecting column 803 to prevent falling down, and the protruding ball bearings 804 give feedback to the performer's soles to feel strange, which is also used to remind the performer to retract his feet; after the performer's feet are retracted, the connecting column 803 is no longer pressed down, and the elastic member 802 stretches to The connecting column 803 is lifted up again, and at the same time, the pressure sensor senses that the connecting column 803 is no longer under pressure, and immediately sends a signal to make the rotation drive component work again, driving the turntable 202 to drive the performer to continue rotating; when the rotation action is completed, the electric lifting platform 001 is controlled to descend, and the lifting frame 3, support frame 4, pedal block 7 and emergency stop controller 8 descend synchronously, so that the top of the ball 804 is flush with the upper surface of the mounting plate 201, to prevent the performer from slipping and falling when stepping on the ball 804 when performing normally on the stage surface.

[0050] During the performance, the performers first move around a large area on the stage surface. In the middle, they need to use the lifting or rotation functions to perform actions. At this time, the performers need to move to the designated center of the stage surface to perform related actions. During performance rehearsals, the performers can remember the approximate location of the lifting area, but they will still actively look for and confirm the detailed location. The stage lights are colorful, which makes it inconvenient for the performers to check the stage surface to find the exact designated location. In addition, the performers frequently look down at the ground, which will affect the look of the performance.

[0051] When the performer needs to move to the center of the turntable 202, first control the electric lifting platform 001 to rise so that the stepping block 7 protrudes from the upper surface of the mounting plate 201. First, the performer can roughly know his position through visual reference. When he needs to accurately move to the center of the turntable 202, he uses his feet to explore the way and touches the stepping block 7 that is higher than the upper surface of the mounting plate 201. Then the performer steps on the stepping block 7 with his feet. As Figure 9 shown, the stepping block 7 will compress the corresponding telescopic rod 6, causing the stepping block 7 to tilt with the connecting rod 5 as the fulcrum, and the tilting direction is towards the center of the turntable 202. Furthermore, the strange feeling of tilting is transmitted to the soles of the performer's feet, prompting the performer to move in the tilting direction to determine the specified position to be moved. Without the performer having to look down at the stage surface, it can prompt the performer to find the exact specified position without affecting the performance view.

[0052] It should be noted that the four stepping blocks 7 are arranged around the turntable 202. The performer confirms the moving direction through one stepping block 7. But after moving too far, he will step on the stepping block 7 in the opposite direction. This stepping block 7 has an opposite tilting direction to the previous one, guiding the performer to step back. Thus, the performer steps on the stepping blocks 7 with different tilting directions to determine the accurate position.

[0053] In addition, after the stepping block 7 rises, the emergency stop controller 8 also rises synchronously. As a result, there are large-scale protrusions on the surface of the mounting plate 201, while the surface of the turntable 202 is a smooth surface. If the performer stands in the area outside the turntable 202, he will feel a strange feeling from the connecting column 803 or the stepping block 7 under his feet. Only when standing on the smooth surface of the central turntable 202 will he not feel strange, thus confirming the current accurate standing position.

[0054] Embodiment 2

[0055] On the basis of Embodiment 1, as Figures 1 - 4 and Figure 13 shown, it further includes a protection component. The protection component includes a protection cloth 21 and fixing rings 22; a protection cloth 21 is wound between two adjacent support feet 402 on the corresponding lifting frame 3 through a torsion spring roller; two fixing buckles 2101 are connected to the free end of the protection cloth 21; two fixing rings 22 are fixedly connected to the bottom of each support column 1.

[0056] The protection cloth 21 is made of nylon material, with high strength and long service life.

[0057] The torsion spring roller for winding the protection cloth 21 is connected to the support foot 402 through a movable bolt, which is convenient for quick disassembly and assembly, and the protection component can be selectively installed, saving the layout time and usage cost.

[0058] The fixing buckle 2101 is connected to the protection cloth 21 through an elastic band; it is convenient to adjust the position of the fixing buckle 2101 to connect with the fixing ring 22.

[0059] When only a part of the stage needs to be raised, there are performers performing on the surface of the unraised stage. It is very easy for the performers' limbs to extend under the raised stage. When the raised stage descends, the limbs are very likely to collide with the parts under the raised stage and get injured. Therefore, when arranging the stage, the worker pulls out the protective cloth 21 from the torsion spring roller and engages it with the fixing ring 22 at the bottom of the adjacent support column 1 through the fixing buckle 2101 to fix the free end of the protective cloth 21. The pulled-out part of the protective cloth 21 will cover between two adjacent support columns 1 and enclose the parts under the stage. When the stage surface rises, the free end of the protective cloth 21 is fixed. Then, the protective cloth 21 is released and pulled out from the torsion spring roller to maintain a full enclosure under the raised stage. When the performers on the unraised stage stretch, their limbs will be blocked by the protective cloth 21 and cannot extend under the raised stage, thus avoiding injury.

[0060] Furthermore, if a performer on the unraised stage falls, due to the pulling force of the torsion spring roller and the fixation of the free end of the protective cloth 21, the pulled-out protective cloth 21 is in a taut state. If a performer on the unraised stage falls towards the raised stage, they will be blocked by the taut protective cloth 21 and will not fall under the raised stage, thus avoiding accidents.

[0061] Moreover, when the present invention is in the unraised state, the protective cloth 21 also blocks between the support columns 1 to enclose the lower side of the stage, preventing children, small animals, etc. at the performance site from running under the stage and getting injured or damaging the stage device.

[0062] The above embodiments are only used to illustrate the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
