Description

[0002] For high-pressure industrial environments such as mines, oil wells, and nuclear reactors, it is often necessary to monitor their working conditions to prevent accidents such as explosions and fires. It is also necessary to detect images so that necessary measures can be taken based on images at the early stage of dangerous situations such as fires and explosions to prevent the situation from becoming serious. However, when an explosion occurs, the thrust generated by the explosion impact will force the active parts of the pan-tilt camera to rotate rapidly. In order to drive the relatively heavy shell and achieve rapid response, the traditional explosion-proof pan-tilt has many transmission mechanisms installed inside. When it is subjected to the instantaneous load generated by the explosion, it is easy to cause the transmission mechanism to be overloaded and damaged. Therefore, it is difficult for the traditional explosion-proof pan-tilt to resume normal use in a short time after the explosion, and the maintenance cost is high. In addition, after the explosion-proof pan-tilt camera is impacted and rotated, its viewing angle will also be greatly offset, making it difficult to continue to monitor the scene.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0018] like Figures 1 to 7 As shown, the present invention provides an embodiment of an explosion-proof pan / tilt platform with a double-sided torque direct-drive motor, comprising a fixed pedestal 1, a rotating pedestal 2 is rotatably mounted on the fixed pedestal 1, shooting devices 4 are rotatably mounted on both sides of the rotating pedestal 2 through rotating shafts 3, the rotating shafts 3 of the shooting devices 4 on both sides are fixedly connected through couplings 5, a base driving mechanism and an equipment driving mechanism are also installed in the rotating pedestal 2, the base driving mechanism comprises a first torque direct-drive motor 6, a base gear set 7 and a bottom protective shell 8, the bottom protective shell 8 is fixed to the inner bottom of the rotating pedestal 2, the base gear set 7 is rotatably mounted in the bottom protective shell 8, the first torque direct-drive motor 6 is fixed on the bottom protective shell 8 and the output shaft is connected to the input end of the base gear set 7, and the output end of the base gear set 7 is connected to the center of the fixed pedestal 1.

[0019] The device driving mechanism includes a second torque direct-drive motor 9, a device gear set 10 and a top protective shell 11. The top protective shell 11 is fixed to the inner wall of the rotating base 2. The device gear set 10 is rotatably installed in the top protective shell 11. The input end of the device gear set 10 is connected to the output shaft of the second torque direct-drive motor 9, and the output end of the device gear set 10 is coaxially fixedly connected to the rotating shaft 3.

[0020] The base gear set 7 and the equipment gear set 10 both include a large gear 12, a transmission gear 13 and a pinion 14. The large gear 12 in the base gear set 7 is fixedly connected to the center of the fixed base 1 through the main shaft. The large gear 12 in the equipment gear set 10 is coaxially fixedly connected to the rotating shaft 3. The large gear 12 is meshed with the transmission gear 13. The transmission gear 13 is coaxially fixedly connected with the pinion 14. The output ends of the first torque direct-drive motor 6 and the second torque direct-drive motor 9 are both fixed with a gear head 15, which is meshed with the pinion 14. In this application, a torque direct-drive motor is used as a power source, eliminating traditional reduction structures such as a reduction box and a pulley, and reducing the transmission gear 13 required for the base gear set 7 and the equipment gear set 10. The simplified structure has stronger impact resistance and can also withstand a larger load to drive the heavy explosion-proof pan / tilt head to respond quickly.

[0021] A reduction and fixing mechanism 16 is provided in both the bottom protective shell 8 and the top protective shell 11. The reduction and fixing mechanism 16 can lock the base gear set 7 and the equipment gear set 10. The reduction and fixing mechanism 16 includes a shaft cylinder 17, a clamping plate 18, a friction plate 19, a sleeve 20 and a compression spring 21. The end of the shaft cylinder 17 is fixed in the bottom protective shell 8 and the top protective shell 11 through the sleeve 20. One end of the clamping plate 18 is vertically slidably sleeved on the sleeve 20. The friction plate 19 is fixed on the surface of the clamping plate 18. The friction plate 19 can abut against the end face of the large gear 12 or the small gear 14. The compression spring 21 is sleeved on the sleeve 20 and its two ends abut against the clamping plate 18 and the sleeve 20 respectively. A through hole 22 with the same inner diameter as the shaft cylinder 17 is opened on the sleeve 20.

[0022] The deceleration and fixing mechanism 16 also includes a limiting arc plate 23, a support shaft 24, a lever 25, a chuck 26, a push-pull ring 27, a push-pull sheet 28, a locking rod 29, a locking sheet 30 and an unlocking spring 31. The end of the support shaft 24 is slidably connected to the friction sheet 19 through a sleeve 32. The lever 25 and the limiting arc plate 23 are respectively fixed on both sides of the support shaft 24. The chuck 26 is fixed to the end of the lever 25. The chuck 26 can be engaged with the shaft cylinder 17 and abut against one side of the clamping sheet 18. One side of the chuck 26 is slidably connected to the push-pull ring 27. The push-pull ring 27 is fixed on The locking rod 29 is fixed to the end of the push-pull piece 28 in the middle part, and the locking rod 29 is slidably inserted into the side of the tube sleeve 20. The unlocking spring 31 is sleeved on the locking rod 29 and the two ends are respectively abutted against the tube sleeve 20 and the push-pull piece 28. The locking piece 30 is installed in the through hole 22 of the tube sleeve 20 and is located below the locking rod 29. The edge of the locking piece 30 is slidably sealed with the inner wall of the tube sleeve 20. A locking tooth 33 is fixed to the top of the locking piece 30. A locking hole 34 that can engage with the locking tooth 33 is opened on the end of the locking rod 29 close to the push-pull piece 28.

[0023] An elastic airbag 35 is abutted against the lower side of the locking piece 30 . The bottom of the elastic airbag 35 is fixed in the shaft tube 17 . There is a gap between the side surface of the elastic airbag 35 and the inner wall of the shaft tube 17 .

[0024] When an explosion occurs, the air near the explosion-proof pan / tilt head will be compressed. The compressed air enters the sleeve 20, pushing the locking plate 30 in the sleeve 20 to move downward, compressing the airbag and causing the locking teeth 33 to disengage from the locking hole 34. Then, the unlocking spring 31 stretches and pushes the push-pull plate 28 and the push-pull ring 27 away from the sleeve 20, thereby driving the clamping head 26 to disengage from the shaft tube 17 and the clamping plate 18. After the clamping plate 18 loses the limit of the clamping head 26, it is pushed by the clamping spring 21 to move toward the large gear 12, causing the friction plate 19 on the surface of the clamping plate 18 to abut against the large gear 12, thereby slowing down the large gear 12 and preventing the large gear 12 from rotating too fast instantaneously and causing damage to the teeth on the edge of the gear.

[0025] After that, the clamp head 26 continues to move in the direction away from the shaft cylinder 17 and the sleeve 20, and the clamp head 26 drives the lever 25 to move. The lever 25 drives the limit arc plate 23 to rotate around the support shaft 24 through the lever principle and approaches the large gear 12 after deceleration. The surface of the limit arc plate 23 is provided with a plurality of ribs to enhance the friction between the limit arc plate 23 and the large gear 12, and the ribs can be stuck in the tooth gap of the large gear 12 to fix the large gear 12 and prevent the large gear 12 from rotating quickly. Compared with the state of gear meshing, the present application uses the limit arc plate 23 to contact with a plurality of teeth, which can block the large gear 12. The force is evenly distributed to multiple teeth, reducing the force on a single tooth, and can better protect the teeth from being damaged by impact while limiting the large gear 12. It should be noted that the small gear 14 is provided with a clamping plate 18, a friction plate 19 and a limiting arc plate 23 of the same structure to decelerate and fix the small gear 14. The deceleration and fixing mechanism 16 can decelerate and fix the large gear 12 and the small gear 14 in a short time, thereby preventing the rotating base 2 and the shooting device 4 from rotating rapidly after being impacted and causing damage to the equipment, and can keep the shooting device 4 at a fixed angle for continued monitoring.

[0026] A reset block 36 is also fixed on the push-pull sheet 28, and the ends of the reset block 36 are located outside the bottom protective shell 8 and the top protective shell 11. When the explosion is over and the air pressure is restored, the elastic airbag 35 is reset to push the locking sheet 30 upward, so that the locking tooth 33 abuts against the surface of the end of the locking rod 29. At this time, after the outer shell of the rotating pedestal 2 is opened, the reset block 36 is directly pressed to retract the locking rod 29 into the sleeve 20. When the locking hole 34 on the locking rod 29 moves to above the locking tooth 33, the elastic airbag 35 can push the locking sheet 30 to continue to move upward, so that the locking tooth 33 enters the locking hole 34, and the locking rod 29 is locked in the sleeve 20 again.

[0027] In addition, when the reset block 36 is pressed, the push-pull plate 28 will push the clamping head 26 close to the shaft cylinder 17 and engage with the shaft cylinder 17. The movement of the clamping head 26 will drive the limiting arc plate 23 to disengage from the large gear 12. The front side of the clamping head 26 is provided with a slope. After the clamping head 26 is close to the shaft cylinder 17 and the limiting arc plate 23 is disengaged from the large gear 12, the front side of the clamping head 26 will abut against the bottom of the clamping plate 18. When the clamping head 26 continues to move, it will push the clamping plate 18 to move upward, so that the clamping plate 18 and the friction plate 19 are also disengaged from the end face of the large gear 12, thereby releasing the limit on the large gear 12, so that the large gear 12 and the small gear 14 can be used normally.

[0028] A magnetic encoder 37 for detecting the rotation angle of the large gear 12 is installed on the bottom protective shell 8 , and a shaft encoder 38 for detecting the rotation angle of the rotating shaft 3 is installed on the top protective shell 11 .

[0029] A processor bracket 39 is also fixed on the top of the rotating platform 2 , and a heat sink fin 40 is fixed on the processor bracket 39 .

[0030] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above are only preferred implementation methods of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the scope of protection of this application.
