Description

Technical Field

[0001] The invention relates to the technical field of cableway camera technology, and in particular to a cableway double-wheel curved surface moving system and a camera system. Background Art

[0002] Compared with the shooting method of fixed camera position, the use of jib-mounted camera equipment or aerial photography can expand the shooting angle and range. However, the jib camera method is still greatly limited in shooting range and angle, and the aerial photography method also has many problems such as unstable images, high noise, and high requirements for shooting height and weather environment.

[0003] At present, the two-dimensional cableway shooting system has been widely used in live recording of sports events such as skiing and athletics, as well as in the shooting of movies. The two-dimensional cableway shooting system uses two parallel cables to form a cableway for carrying camera equipment, so that the equipment can change the shooting position in the extension direction of the cables, thereby achieving low noise and stable picture effects while accurately controlling the shooting. However, in the two-dimensional cableway shooting system, the position and shooting angle of the shooting equipment are still limited by the extension direction of the cableway.

[0004] Some people have tried to design a camera platform with three or more slings to achieve three-dimensional cableway control of the camera platform. However, three-dimensional cableway control requires three or four large winches to be installed at the recording site, and then a large metal bracket is set up. Each winch is connected with a steel wire rope, and then the steel wire rope is guided to the upper end of the large metal bracket. Then the camera pan-tilt mechanism and camera equipment are connected, and the steel wire rope and winch are restrained by the gravity of the pan-tilt mechanism and camera equipment to form a multi-directional traction suspension device. It can obtain a shooting picture with a strong visual impact from a unique aerial motion perspective.

[0005] However, in actual application, the 3D ropeway needs to set up large metal brackets and multiple large winch units on site, which is time-consuming and labor-intensive, requires multiple workers to build together, and is extremely inconvenient to transport. Moreover, debugging after construction is also an arduous project and very expensive. In addition, due to site restrictions, some sites are not suitable for setting up such complex and space-consuming equipment, which greatly limits the application of 3D ropeway shooting.

[0006] In view of the above-mentioned defects, the inventors of the present invention finally obtained the present invention after a long period of research and practice. Summary of the invention

[0057] Figure 1 The double-wheel curved surface moving system of a cableway according to an embodiment of the present invention is schematically shown. Figure 1 As shown, the cableway double-wheel curved surface moving system includes a first fixed point 1, a second fixed point 2, a first fixed pulley 3, a second fixed pulley 4, a sling 5 and a moving device, the moving device includes a driving pulley group and a power mechanism (not shown in the figure), the power mechanism includes a first power device and a second power device, the first power device drives the first driving pulley to rotate; the second power device drives the second driving pulley to rotate; the driving pulley group includes a first driving pulley 61 and a second driving pulley 62 connected to each other. The first fixed point 1, the second fixed point 2, the first fixed pulley 3, and the second fixed pulley 4 are sequentially located at the four endpoints of a quadrilateral. One end of the sling 5 is connected to the second fixed point 2, and the other end is connected to the first fixed point 1 by bypassing the first fixed pulley 3 and the second fixed pulley 4 in turn. The sling 5 between the second fixed point 2 and the first fixed pulley 3 bypasses the second driving pulley 62, and the sling 5 between the first fixed point 1 and the second fixed pulley 4 bypasses the first driving pulley 61. The moving device is located below the plane where the quadrilateral is located. The first fixed point 1, the second fixed point 2, the first fixed pulley 3, and the second fixed pulley 4 may not be on the same plane, and their vertical projections are sequentially located at the four endpoints of a quadrilateral, and the sling is in a non-tensioned state.

[0058] Figure 2 , Figure 3shows Figure 1 The moving state of the cableway double-wheel curved surface moving system shown in the figure, the cableway double-wheel curved surface moving system also includes a controller, the controller is electrically connected to the first power device and the second power device, and is used to control the output rotation direction and speed of the first power device and the second power device.

[0059] like Figure 2 As shown, the vertical direction is set as the Y axis and the horizontal direction is set as the X axis. When the controller controls the output of the first power device and the second power device to make the first driving pulley 61 and the second driving pulley 62 rotate in the same direction, the mobile device moves along the X axis, that is, when the first driving pulley 61 and the second driving pulley 62 rotate clockwise at the same time, the mobile device moves to the left, and when the first driving pulley 61 and the second driving pulley 62 rotate counterclockwise at the same time, the mobile device moves to the right. When the controller controls the output of the first power device and the second power device to make the first driving pulley 61 and the second driving pulley 62 rotate in opposite directions, the mobile device moves along the Y axis, that is, when the first driving pulley 61 rotates counterclockwise and the second driving pulley 62 rotates clockwise, the mobile device moves downward, and when the first driving pulley 61 rotates clockwise and the second driving pulley 62 rotates counterclockwise, the mobile device moves upward.

[0060] like Figure 3 As shown, the mobile device is located below the plane where the quadrilateral is located, that is, the sling 5 cannot be in a taut state. When the length of the sling 5 between the first fixed point 1 and the second fixed point 2 is fixed, the mobile device can only move on a fixed curved surface. Preferably, the first fixed point 1, the second fixed point 2, the first fixed pulley 3, and the second fixed pulley 4 are located at the four ends of a rectangle in sequence. It can be understood that the selection of a rectangular arrangement method has a larger range of movement of the mobile device, and the force on the driving pulley, the fixed point and the fixed pulley is more uniform, which is more conducive to smooth movement. By coordinating the speed and rotation direction of the driving pulley, the mobile device can be moved to any point on the curved surface.

[0061] Figure 4 The cableway double wheel curved surface moving system of another specific embodiment is schematically shown. Figure 4 As shown, in Figure 1On the basis of the scheme, a third fixed pulley 7 is provided on the first fixed point 1, and a fourth fixed pulley 8 is provided on the second fixed point 2. The two ends of the sling 5 are connected to a winch 9 after passing through the third fixed pulley 7 and the fourth fixed pulley 8 respectively. The winch 9 can release or retract the same length of the sling 5 to the third fixed pulley and the fourth fixed pulley respectively at the same time. It can be understood that after the winch 9 releases or retracts a certain length of the sling 5, the length of the sling between the four fixed pulleys changes, and the height and shape of the curved surface where the moving range of the mobile device is located are changed, so that the mobile device can be moved arbitrarily in a three-dimensional space by changing the length of the sling, and its specific moving path can be controlled by the controller. Preferably, the winch is an electric winch. It can be understood that the winch 9 can also be replaced by other sling length adjustment devices, such as a ratchet device, a slot device, etc. In this embodiment, the winch 9 can simultaneously release or retract the same length of the sling 5 toward the third fixed pulley and the fourth fixed pulley. Since the increased or shortened lengths at both ends of the sling 5 are the same, it is beneficial to control the stability of the mobile device and can more accurately control the moving position of the mobile device.

[0062] In other embodiments, the sling length adjustment device may also adjust the length of only one end of the sling 5, that is, only the third fixed pulley 7 is provided on the first fixed point 1, or the fourth fixed pulley 8 is provided on the second fixed point 2, and the sling length adjustment device is connected to the sling extending from the third fixed pulley 7, or is connected to the sling extending from the fourth fixed pulley 8. By changing the length of the sling, the curved surface where the moving range of the moving device is located is changed.

[0063] Alternatively, the sling length adjustment device may be connected to other positions of the sling, but it is necessary to avoid interfering with the movement of the driving pulley.

[0064] Figure 5 , Figure 6 is a structural diagram of an embodiment of a mobile device of the present invention, such as Figure 5As shown, the moving device 6 includes a first driving pulley 61, a second driving pulley 62, a support plate 65, four cable guides 63 and at least two jumper wheels 64; the support plate 65 is a disc structure, the first driving pulley 61 and the second driving pulley 62 are rotatably arranged on the support plate 65 at intervals, the center line of the first driving pulley 61 and the second driving pulley 62 passes through the center of the support plate 65, and the two driving pulleys 61 and 62 are symmetrical relative to the center of the support plate 65; the four cable guides 63 are fixed to the support plate 6 5, which are located on the same circumference and the four cable guides 63 are respectively located at the four endpoints of a rectangle, the center of the circle coincides with the center of the support plate, and the two opposite sides of the rectangle are parallel to the center line connecting the first and second driving pulleys 61 and 62 and are greater than the length of the center line; the jumper wheel 64 is rotatably connected to the support plate 65, the two jumper wheels 64 are located on the extension line of the center line connecting the first and second driving pulleys 61 and 62, and the two jumper wheels 64 are symmetrical with respect to the center of the support plate 65. The sling 5 extending from the second fixed point 2 passes through the rope guide 63 above the outer side of the second driving pulley 62, winds several turns between the second driving pulley 62 and the jumper wheel 64 outside the second driving pulley 62, then bypasses the second driving pulley 62 and passes through the rope guide 63 below the outer side of the second driving pulley 62. The sling passes through the first fixed pulley 3 and the second fixed pulley 4, then passes through the rope guide 63 below the outer side of the first driving pulley 61, winds several turns between the first driving pulley 61 and the jumper wheel 64 outside the first driving pulley 61, then bypasses the first driving pulley 61 and passes through the rope guide 63 above the outer side of the first driving pulley 61. A protective shell 66 is encapsulated above the support plate 65.

[0065] Optionally, there may be more than four rope guides 63, such as eight, arranged in groups of two; there may be more than two jumper wheels 64, such as four, and every two jumper wheels 64 and a driving pulley form a triangular position relationship, and the sling wraps around two jumper wheels 64 and a driving pulley to further increase friction.

[0066] Since the sling is wound several times between the driving pulleys 61, 62 and the jumper wheel 64 outside thereof, the friction between the driving pulleys 61, 62 and the sling is increased, so that the driving pulleys 61, 62 can reliably pull the sling and move in space.

[0067] Preferably, a plurality of corresponding annular guide grooves for winding the sling are provided on the circumferential surfaces of the driving pulleys 61, 62 and the jumper wheel 64, so as to prevent the sling from getting tangled when winding and further increase the friction and the smoothness of the sliding of the sling.

[0068] like Figure 6As shown, a battery 67, a communication module 68 and a controller 69 are also provided on the support plate 65. The first power device and the second power device are preferably motors. The battery 67 can power the motor and the controller 69, and can also power other devices carried by the mobile device 6. The communication module 68 is connected to the controller 69. The communication module 68 is used to receive remote control command signals and transmit them to the controller. The communication module 68 can also transmit data of external carried devices, such as image data of a camera.

[0069] Figure 7 and Figure 8 : is a three-dimensional structural diagram of the cable guide of the present invention. The cable guide 63 includes a bracket, two parallel vertical guide rollers 631 and a transverse guide roller 632. The vertical guide roller 631 and the transverse guide roller 632 are rotatably fixed on the bracket. The axis of the vertical guide roller 631 is perpendicular to the axis of the transverse guide roller 632, and the transverse guide roller 632 is located behind the two vertical guide rollers. There is a gap between the two parallel vertical guide rollers 631 for the sling to pass through. The distance between the vertical guide roller 631 and the transverse guide roller 632 is greater than the diameter of the sling. A through groove 633 is provided on the bracket above the gap between the two vertical guide rollers 631 and above the gap between the vertical guide roller 631 and the transverse guide roller 632 to facilitate the insertion of the sling 5. When the cable guide 63 is installed on the support plate 65, the transverse guide roller 632 faces the driving pulleys 61 and 62, and the vertical guide roller 631 faces the outside of the moving device 6. The guide rope passes through the gap between the two vertical guide rollers 631, and then passes under the transverse guide roller 632. The vertical guide roller 631 and the transverse guide roller 632 define the moving route of the sling, and allow the sling to pass through the guide rope device 63 more smoothly.

[0070] In a specific application embodiment of the present invention, a camera system is provided, comprising a camera device and the above-mentioned cableway double-wheel curved surface moving system, wherein the camera device is mounted on the moving device.
