[0055] like Figure 11-Figure 12 As shown, before switching the position of the recording device, the recording device is mostly tightened and fixed manually, and the recording device cannot be automatically clamped and positioned, which is time-consuming and laborious. A positioning assembly 12 is provided on the top frame 6, and the positioning assembly 12 includes a second electric push rod 121 embedded in another output shaft of the double-headed motor 3, and the piston rod of the second electric push rod 121 is fixedly connected to a driving bevel gear 122 that penetrates and cooperates with the top frame 6, and a driven bevel gear 123 is provided on one side above the driving bevel gear 122, and the meshing stroke between the driving bevel gear 122 and the driven bevel gear 123 is adjusted by the second electric push rod 121;

[0057] A three-dimensional mobile recording device for broadcasting and television recording. Working principle: first, after placing the recording device in the placement seat 14 on the top frame 6, control the second electric push rod 121 to start and drive the driving bevel gear 122 to penetrate the top frame 6 upward to the meshing part of the driven bevel gear 123, then control the double-headed motor 3 to start and drive the driven bevel gear 123 to rotate through the meshing driving bevel gear 122, and the driven bevel gear 123 drives the forward and reverse threaded rod 124 to rotate forwardly, and the forward and reverse threaded rod 124 drives the two sets of screws. The threaded sleeves 125 move inward synchronously. After the two sets of threaded sleeves 125 drive the rubber pads on the two sets of positioning seats 126 to automatically clamp and position the recording device, the double-headed motor 3 is first controlled to pause, and then the second electric push rod 121 is controlled to close and drive the driving bevel gear 122 downward to disengage from the meshing portion of the driven bevel gear 123 to the initial position. At this time, the two sets of positioning seats 126 still maintain the clamping and positioning state of the recording device, and then the four sets of driving motors are controlled to start and drive the four sets of Mecanum wheels 15 to move to the recording range;

[0058] If it is necessary to adjust the longitudinal height of the recording device in the positioned state, first control the first electric push rod 81 to open and drive the locking head 82 to move down and get stuck in the locking seat 83, then control the double-headed motor 3 to open again, and drive the screw rod 84 to rotate forward or reversely through the locking head 82 and the locking seat 83 that are stuck in place. At this time, the driving bevel gear 122 on the second electric push rod 121 is in an idling state, and the screw rod 84 rotating forward or reversely drives the screw rod sleeve 85 to move upward or downward, and the screw rod sleeve 85 drives the sealing cylinder 7 on the two groups of support arms 86 to move upward or downward accordingly, and the two groups of sealing cylinders 7 drive the recording device on the top frame 6 to adjust the height upward or downward through the two groups of sliding rod frames 112 in the initial adsorption state, until the height of the recording device in the positioned state is adjusted to the requirements of the news shooting position, first control the double-headed motor 3 to pause, and then control the first electric push rod 81 to close and drive the locking head 82 to move up and away from the locking seat 83 to the initial state;

[0059] If it is necessary to adjust the lateral displacement of the recording device in the positioning state, the double-headed motor 3 is controlled to be restarted and drive the main synchronous wheel 91 to rotate. The main synchronous wheel 91 drives the two sets of auxiliary synchronous wheels 92 to rotate synchronously through the synchronous belt. The two sets of auxiliary synchronous wheels 92 drive the two sets of concave rods 93 to rotate synchronously. The two sets of concave rods 93 drive the piston heads 96 on the two connecting rods 95 through the two sets of rotating sleeves 94 to reciprocate in the two sets of piston cylinders 5. Then the pressurized air source generated by the work in the two sets of piston cylinders 5 is supplied to the two sets of air storage tanks 102 through the two exhaust pipes 101 for temporary storage, and is supplied to the two three-way pipes 104 through the two telescopic tubes 103 in the stretched state following the two sets of sealing cylinders 7. According to the horizontal displacement adjustment requirement of the current recording device, if it is necessary to adjust the horizontal displacement of the recording device to the left, the sealing chamber 105 on the left side of the two sets of sealing cylinders 7 is controlled to be opened through the two sets of reversing valves 106, and the sealing chamber 105 on the right side of the two sets of sealing cylinders 7 is in a closed state.

[0060] The two sets of circuit breakers 116 located on the left are controlled to open and energize the electromagnets 115. After being energized, the two sets of electromagnets 115 electromagnetically attract the adsorption magnets 114 on the two slide rod racks 112 located on the left. The two sets of circuit breakers 116 located on the right are closed and do not energize the electromagnets 115 at their positions. Then, the adsorption magnets 114 on the two slide rod racks 112 located on the right are in a disengaged state. After the pressurized gas source in the two three-way pipes 104 is supplied to the sealed chamber 105 on the left side of the two sets of sealing cylinders 7, as the pressurized gas source The pressure increases rapidly with continuous supply. Under the action of the pressure, the two sets of sliding seats 111 in the left sealed chamber 105 are forced to slide outward. The two sets of sliding seats 111 drive the two sliding rod racks 112 on the left to move outward horizontally synchronously and squeeze the two sets of return springs 113 thereon. The two sliding rod racks 112 on the left drive the recording device on the top frame 6 to move horizontally to the left through the two sets of adsorption magnets 114 and the electromagnet 115 in the electromagnetic adsorption state. After the recording device moves horizontally to the left to reach the predetermined position, the air supply is stopped.

[0061] If it is necessary to adjust the horizontal displacement of the recording device to the right, first control the air relief valves on the two pressure relief pipes 13 to open, then the pressurized air source supplied to the sealed chamber 105 on the left side of the two sets of sealing tubes 7 is discharged through the two pressure relief pipes 13, and under the elastic restoring force of the two return springs 113 in the compressed state, the two slide rod frames 112 that are displaced to the left are forced to drive the recording device on the top frame 6 to move back and reset to the initial centered state, and then control the air relief valves on the two pressure relief pipes 13 to close, conversely, the sealed chamber 105 on the right side of the two sets of sealing tubes 7 is opened through the two sets of reversing valves 106, then the sealed chamber 105 on the left side of the two sets of sealing tubes 7 is opened. The sealing chamber 105 is in a closed state, and the two sets of circuit breakers 116 located on the right side are controlled to open and energize the electromagnet 115. After being energized, the two sets of electromagnets 115 electromagnetically attract the adsorption magnets 114 on the two sliding rod racks 112 located on the right side, and the two sets of circuit breakers 116 located on the left side are closed and do not energize the electromagnets 115 at their positions. Similarly, the two sliding rod racks 112 on the right side drive the recording device on the top frame 6 to move horizontally to the right through the two sets of adsorption magnets 114 and the electromagnet 115 in the electromagnetic adsorption state. After the recording device moves horizontally to the right and reaches the predetermined position, the air supply is stopped.

[0062] It should be noted that the specific models and specifications of the double-headed motor 3, the drive motor, the first electric push rod 81, the circuit breaker 116 and the second electric push rod 121 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
