Description

Technical Field

[0001] The present invention relates to the technical field of traction equipment, and in particular to a platform-electrically driven unmanned traction equipment and method for virtual shooting. Background Art

[0002] In the construction of a photography stage for virtual shooting, a set-making circular table is needed to arrange the site, and then the set-making circular table is moved away and a shooting circular table is placed, so that the staff can shoot the site. Therefore, the set-making circular table and the shooting circular table need to be interchanged. When interchanged, manual operation is inefficient. Currently, guide rails and traction devices are set, and the traction device locks the circular table, and then moves it along the guide rails, thereby replacing manual operation to complete the interchange of the two circular tables.

[0003] In the aforementioned prior art, the traditional pulley and linear guide rail are used for traction. However, when the site is built for the virtual shooting of science and technology films and televisions, the on-site conditions are complicated and there are many obstacles. Therefore, relying solely on linear traction cannot meet the transportation and interchange of the truncated table. However, after setting up an arc or circular guide rail, the contact point will change when the pulley rotates in the arc. At the same time, if it moves too fast in the arc, centrifugal force and centripetal force will appear, which will eventually lead to uneven contact between the pulley and the guide rail. The pulley is easy to deviate from the track, affecting the stability of the traction of the truncated table during the virtual shooting of science and technology films and televisions.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0034] See also Figures 1 to 6 The present invention provides a platform-based electrically driven unmanned traction device for virtual shooting, comprising a slide rail 1, an electrically driven universal wheel 2, a traction block 3, a docking locking unit, a position sensor 4 and a traction stabilization component, wherein the traction stabilization component comprises a sliding column 5, two spheres 6, two limit blocks 7 and a holding pulley 8, the slide rail 1 has a slide groove 9, the traction stabilization component further comprises a holding unit, the holding unit comprises a first spring 10, a telescopic rod 11 and a mounting block 12, the traction block 3 has a groove 13, and the traction stabilization component further comprises an anti-bias unit, The anti-deflection unit includes a support block 14, a rotating frame 15, an anti-deflection rod 16, multiple anti-deflection grooves 17, a reset mechanism and a limit mechanism. The reset mechanism includes multiple second springs 18 and an electric retracting rod 19. The limit mechanism includes a support plate 20, an electric push rod 21, a limit frame 22, a limit groove 23 and a limit block 7. The docking locking unit includes a lifting component 25, a telescopic component 26, a rotating component 27, a U-shaped plate 28, an electronic suction cup 29, a fixed block 32 and two clamping mechanisms. The clamping mechanism includes a clamping component 30 and a clamping plate 31.

[0035] Among them, the electrically driven universal wheel 2 is arranged above the traction block 3 and located inside the slide rail 1, the docking locking unit is arranged below the traction block 3, the position sensor 4 is arranged on the docking locking unit, the slide rail 1 has a slide groove 9, the sliding column 5 is fixedly connected to the traction block 3 and located above the traction block 3, the sliding column 5 is slidably connected to the slide groove 9, the two balls 6 are symmetrically arranged on the outside of the sliding column 5, and are both slidably connected to the slide rail 1, the two limit blocks 7 are both located inside the slide rail 1, and are symmetrically distributed on both sides of the electrically driven universal wheel 2, and the abutting pulley 8 is arranged on one side of the slide rail 1 and abuts against the slide rail 1. The slide rail 1 is fixed above the indoor stage; when the stage needs to be set up, the electrically driven universal wheel 2 is started to drive the traction block 3 to slide on the slide rail 1; the sliding column 5 and the two balls 6 slide in the slide groove 9 to maintain stability and prevent the traction block 3 from shifting. At the same time, the limit block 7 limits the two sides of the wheel body of the electrically driven universal wheel 2 to avoid poor contact caused by erroneous rotation and shifting at the arc. The abutting pulley 8 abuts against one side of the slide rail 1 so that when it is at the arc, it can always contact with the slide rail 1 due to its elasticity, thereby maintaining good contact, so that the traction process can remain stable; the position of the scenery truncated table is monitored by the position sensor 4; the docking locking unit is operated to lock the scenery truncated table, and then it is towed and transferred along the slide rail 1; the shooting truncated table is towed and placed in a suitable position to complete the replacement operation.

[0036] Secondly, the abutting unit is arranged on the traction block 3; the traction block 3 has a groove 13, the two ends of the telescopic rod 11 are respectively fixedly connected to the inner wall of the groove 13 and the mounting block 12, the two ends of the first spring 10 are respectively movably connected to the inner wall of the groove 13 and the mounting block 12, the first spring 10 is sleeved on the outside of the telescopic rod 11, and the abutting pulley 8 is arranged on one side of the mounting block 12. The first spring 10 drives the mounting block 12 to contract, and the telescopic rod 11 follows the contraction to maintain stability, so that the abutting pulley 8 is always in abutting contact with one side of the slide rail 1.

[0037] Meanwhile, the anti-bias unit is arranged on the traction block 3; the support block 14 is arranged on one side of the traction block 3, the rotating frame 15 is rotatably connected to one end of the support block 14, the anti-bias rod 16 is arranged on one end of the rotating frame 15, a plurality of anti-bias grooves 17 are arranged in sequence on the side of the slide rail 1 away from the abutting pulley 8, the anti-bias rod 16 is adapted to any anti-bias groove 17, the reset mechanism is arranged on the other end of the rotating frame 15, and the limiting mechanism is arranged on the traction block 3. The support block 14 supports the rotating frame 15, and after the limiting mechanism releases the limit of the reset mechanism, the reset mechanism drives the rotating frame 15 to rotate, thereby making the anti-bias rod 16 enter the corresponding anti-bias groove 17, thereby fixing the traction block 3, improving the stability when locking the truncated table, and avoiding the displacement of the traction block 3 during locking, resulting in locking failure.

[0038] In addition, both ends of the plurality of second springs 18 are movably connected to one side of the traction block 3 and the other end of the rotating frame 15, respectively. Both ends of the electric retracting rod 19 are rotatably connected to one side of the traction block 3 and the other end of the rotating frame 15, respectively. Two second springs 18 are located at both ends of the electric retracting rod 19. The second spring 18 drives the rotating frame 15 to rotate, thereby causing the anti-bias rod 16 to enter the anti-bias groove 17. When the limit needs to be released, the electric retracting rod 19 is started to drive the rotating frame 15 to reset. At this time, in order to prevent the second spring 18 from repeatedly pushing the rotating frame 15, the limit mechanism is used to limit the rotating frame 15. When the round table needs to be locked, the limit of the rotating frame 15 is released again.

[0039] Then, the support plate 20 is arranged below the traction block 3, the output end of the electric push rod 21 is arranged above the support plate 20, the output end of the electric push rod 21 is fixedly connected to the limit frame 22, the limit groove 23 is arranged on the inner side wall of the limit frame 22, the limit member 24 is arranged at the other end of the rotating frame 15, and the limit member 24 and the limit groove 23 are adapted to each other. The support plate 20 supports the electric push rod 21, and the electric push rod 21 is started, driving the limit frame 22 to move up, and then sleeved on the outside of the limit piece 24 of the rotating frame 15. At this time, the electric retracting rod 19 is closed, and the second spring 18 drives the rotating frame 15 to rebound, so that the limit piece 24 enters the limit groove 23, so that the rotating frame 15 cannot continue to rotate clockwise. When the limit needs to be released, the electric retracting rod 19 is first started to drive the rotating frame 15 to rotate counterclockwise, and the limit piece 24 disengages from the limit groove 23, and then the limit frame 22 moves down again, thereby completely releasing the limit of the rotating frame 15. At this time, the electric retracting rod 19 is closed again, and the second spring 18 rebounds, driving the rotating frame 15 and the anti-deflection rod 16 to rotate.

[0040] Again, the lifting component 25 is arranged below the traction block 3, the output end of the lifting component 25 is fixedly connected to the telescopic component 26, the output end of the telescopic component 26 is fixedly connected to the fixed block 32, the rotating component 27 is arranged on the fixed block 32, the output end of the rotating component 27 passes through the fixed block 32 and is fixedly connected to the U-shaped plate 28, the electronic suction cup 29 is arranged on the inner top wall of the U-shaped plate 28, the position sensor 4 is arranged below the fixed block 32, and the two clamping mechanisms are symmetrically arranged on the U-shaped plate 28.

The lifting component 25 is started to adjust the clamping height, the telescopic component 26 is started to adjust the front and rear position, and the rotating component 27 is started to adjust the angle of the U-shaped plate 28, and then the truncated table is clamped by the clamping mechanism, and at the same time, the electronic suction cup 29 adsorbs the top of the truncated table to reduce the pressure of the clamping mechanism and improve the stability of the traction truncated table.

[0041] Furthermore, the clamping component 30 is disposed on one side of the U-shaped plate 28, and the output end of the clamping component 30 passes through the U-shaped plate 28 and is fixedly connected to the clamping plate 31. The clamping component 30 is a cylinder, and when the clamping component 30 is started, the clamping plate 31 is driven to move, thereby clamping and fixing the truncated table.

[0042] When using the electric-driven unmanned traction device for a platform for virtual shooting of the present embodiment, the slide rail 1 is installed and fixed above the indoor stage; when the stage needs to be set up, the electric-driven universal wheel 2 is started to drive the traction block 3 to slide on the slide rail 1; the sliding column 5 and the two balls 6 slide in the slide groove 9 to maintain stability and avoid the displacement of the traction block 3. At the same time, the limit block 7 limits the two sides of the wheel body of the electric-driven universal wheel 2 to avoid poor contact caused by erroneous rotation and displacement in the arc. The abutting pulley 8 abuts against one side of the slide rail 1 so that when it is in the arc, due to the elasticity of the abutting pulley 8, it can always contact with the slide rail 1, thereby maintaining good contact, so that the traction process can remain stable; the position of the landscape circular table is monitored by the position sensor 4; the docking locking unit is operated to lock the landscape circular table, and then the stage is moved along the The slide rail 1 pulls it to transfer; the pulling shooting truncated table is placed in a suitable position to complete the replacement operation; through the above-mentioned structural setting, when the traction block 3 moves, the traction block 3 is limited by the sliding column 5 and the two balls 6; so that at the arc turning point, when the electric drive universal wheel 2 turns, the traction block 3 can move stably along the slide rail 1 and will not be deviated by the electric drive universal wheel 2. At the same time, the two sides of the wheel body of the electric drive universal wheel 2 are limited by the limiting block 7, so that the electric drive universal wheel 2 will not turn arbitrarily in the slide rail 1, so that it can only rotate in the direction of the slide rail 1, further maintaining stability and avoiding deviation and shaking. In addition, relying on the effect of the abutting pulley 8, the traction block 3 can always maintain good contact with the slide rail 1 whether in a straight line or an arc area, so that the traction process can remain stable.
