DETAILED DESCRIPTION

[0035] 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.

[0036] The core of the present invention is to provide an automatic cover opening and closing device for an oxygen bomb, which can automatically open and close the cover of the oxygen bomb, effectively reducing labor costs and reducing the labor intensity of operators.

[0037] Another core of the present invention is to provide an oxygen bomb suitable for the above-mentioned automatic oxygen bomb cover opening and closing device, which can make the automatic cover opening and closing operation of the oxygen bomb smoother.

[0038] Please refer to Figures 1 to 10 ,in, Figure 1 This is a front view of the automatic cover opening and closing device for the oxygen bomb provided by the present invention; Figure 2 It is a side view of the automatic cover opening and closing device of the oxygen bomb; Figure 3 It is a front view of the oxygen bomb cover supporting device; Figure 4 It is a left side view of the oxygen bomb cover supporting device; Figure 5 is a top view of the oxygen bomb cover support device; Figure 6 It is the front view of the oxygen bomb cylinder rotating device; Figure 7 It is a left side view of the oxygen bomb cylinder rotating device; Figure 8 This is a front view of the oxygen bomb cylinder lifting device; Fig. 9 This is a front view of the oxygen bomb provided by the present invention; Fig.10 A top view of the oxygen bomb.

[0039] The present specific embodiment provides an oxygen bomb automatic cover opening and closing device, comprising: an oxygen bomb cover supporting device 1 for clamping and fixing an oxygen bomb cover 13, an oxygen bomb rotating device 2 rotatably used to support an oxygen bomb 21, an oxygen bomb lifting device 3 for driving the oxygen bomb rotating device 2 to move up and down, and a control device. The oxygen bomb cover supporting device 1 is arranged at the top of the oxygen bomb lifting device 3. The oxygen bomb lifting device 3 comprises a track 31 arranged in a vertical direction and a moving device 33 for moving on the track 31. The oxygen bomb rotating device 2 is arranged on the moving device 33. When the moving device 33 moves to the top of the track 31, the oxygen bomb 21 contacts the oxygen bomb cover 13. The control device is respectively connected to the oxygen bomb cover supporting device 1, the oxygen bomb rotating device 2 and the moving device 33 to control the fixing process of the oxygen bomb cover 13, the rotation process of the oxygen bomb 21, and the movement process of the moving device 33.

[0040] It should be noted that, here, when the moving device 33 moves to the top of the track 31, the oxygen bomb 21 contacts the oxygen bomb cover 13, so as to facilitate the subsequent rotation of the oxygen bomb 21 so that the oxygen bomb 21 and the oxygen bomb cover 13 can be tightened and fixed to each other.

[0041] Preferably, the oxygen bomb cover supporting device 1 may be provided with a movable clamping member, and when the clamping members are close to each other, a clamping hole for clamping the oxygen bomb cover 13 may be formed, so as to facilitate the placement and fixing of the oxygen bomb cover 13. When the clamping members are away from each other, the oxygen bomb cover 13 may be conveniently removed.

[0042] In actual use, the structure, size, shape, position, etc. of the oxygen bomb cover supporting device 1, the oxygen bomb cylinder rotating device 2, the oxygen bomb cylinder lifting device 3 and the control device can be determined according to actual conditions and actual needs.

[0043] In addition, it should be noted that when the oxygen bomb automatic cover opening and closing device provided by the present invention is used to close the oxygen bomb, first, the oxygen bomb cylinder 21 can be placed on the oxygen bomb cylinder rotating device 2 by the manipulator device, and the oxygen bomb cover 13 can be placed on the oxygen bomb cover supporting device 1 by the manipulator device. Then, the oxygen bomb cover supporting device 1 is controlled by the control device to fix the oxygen bomb cover 13, and then the moving device 33 is controlled to move upward along the moving vertical track 31 to the position where the oxygen bomb cylinder 21 contacts the oxygen bomb cover 13. Finally, the control device can control the oxygen bomb cylinder rotating device 2 to rotate so that the oxygen bomb cylinder 21 and the oxygen bomb cover 13 are tightened and fixed together, thereby completing the closing operation of the oxygen bomb.

[0044] In addition, when the oxygen bomb automatic cover opening and closing device provided by the present invention is used to open the cover of the oxygen bomb, first, the oxygen bomb in the closed state can be placed on the oxygen bomb cover support device 1 by the manipulator device. Then, the oxygen bomb cover support device 1 is controlled by the control device to fix the oxygen bomb cover 13, and then the moving device 33 is controlled to move upward along the moving vertical track 31 to a position in contact with the oxygen bomb cylinder 21. Afterwards, the control device can control the oxygen bomb cylinder rotating device 2 to rotate in the opposite direction so that the oxygen bomb cylinder 21 and the oxygen bomb cover 13 are released from each other. Finally, the control device can control the moving device 33 to move downward along the moving vertical track 31 so that the oxygen bomb cylinder 21 is separated from the oxygen bomb cover 13, thereby completing the opening operation of the oxygen bomb.

[0045] Therefore, the automatic oxygen bomb lid opening and closing device provided by the present invention can cooperate with the manipulator to automatically complete the oxygen bomb lid opening and closing operations during the calorimeter experiment, thereby effectively reducing the labor cost during the operation and the labor intensity of the operator.

[0046] In summary, the automatic opening and closing device for the oxygen bomb provided by the present invention has a simple structure and is easy to operate. It can automatically open and close the oxygen bomb, and it can effectively reduce labor costs and reduce the labor intensity of operators.

[0047] On the basis of the above-mentioned oxygen bomb automatic opening and closing device, preferably, the oxygen bomb cover supporting device 1 includes an oxygen bomb cover supporting frame 11 for connecting to the top of the oxygen bomb cylinder lifting device 3, a movable oxygen bomb cover clamping plate 14 for clamping and fixing the oxygen bomb cover 13, and a driving cylinder 12 for driving the oxygen bomb cover clamping plate 14 to move, the driving cylinder 12 is connected to the oxygen bomb cover clamping plate 14, the driving cylinder 12 and the oxygen bomb cover clamping plate 14 are both arranged on the oxygen bomb cover supporting frame 11, and the control device is connected to the driving cylinder 12 to control the movement of the oxygen bomb cover clamping plate 14.

[0048] Therefore, the control device can control the movement of the driving cylinder 12, and the driving cylinder 12 can drive the oxygen bomb cover clamping plate 14 to move during the movement. When the oxygen bomb cover clamping plates 14 are close to each other, the two can form a clamping hole for clamping the oxygen bomb cover 13, so as to facilitate the placement and fixing of the oxygen bomb cover 13. When the oxygen bomb cover clamping plates 14 are away from each other, the oxygen bomb cover 13 can be easily taken out.

[0049] Preferably, the size of the positioning hole is slightly larger than the size of the oxygen bomb cover 13, so that the oxygen bomb cover 13 has a certain amount of free movement. For example, a 0.5 mm gap can be provided between the positioning hole and the oxygen bomb cover 13, so that the oxygen bomb cover 13 can have a small displacement in the hole. Such a setting can avoid the oxygen bomb cover 13 and the oxygen bomb cover support device 1 from getting stuck, and it is more convenient to open the cover between the oxygen bomb cover 13 and the oxygen bomb cylinder 21. In addition, the oxygen bomb cover positioning plate 14 can be provided with a groove matching the size of the protrusion of the oxygen bomb cover 13, and the groove can effectively clamp the protrusion structure on the oxygen bomb cover 13 to limit the circumferential movement of the oxygen bomb cover 13, and finally effectively fix the oxygen bomb cover 13.

[0050] Preferably, a magnetic sensor for detecting the position state of the oxygen bomb cover locking plate 14 is provided on the driving cylinder 12, and the magnetic sensor is connected to the control device to transmit a position signal of the oxygen bomb cover locking plate 14 to the control device.

[0051] Therefore, the control device can receive the position signal of the oxygen bomb cover locking plate 14 in real time, so as to timely adjust and control the driving cylinder 12, so that the driving cylinder 12 drives the oxygen bomb cover locking plate 14 to move closer to or away from each other, thereby facilitating the operation of placing and fixing the oxygen bomb cover 13 or taking out and removing the oxygen bomb cover 13.

[0052] In actual use, the structure, size, shape, position, etc. of the oxygen bomb cover support frame 11, the oxygen bomb cover positioning plate 14, and the driving cylinder 12 can be determined according to actual conditions and actual needs.

[0053] On the basis of the above-mentioned oxygen bomb automatic opening and closing device, preferably, the oxygen bomb cover supporting device 1 includes a first oxygen bomb detection device 15 at a high position and a second oxygen bomb detection device 16 at a low position arranged along the height direction of the oxygen bomb cover supporting frame 11, and the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 are both connected to the control device to transmit detection signals to the control device. When the signals of the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 are both blocked or connected, it means that the oxygen bomb cover 13 and the oxygen bomb cylinder 21 fail to close. When the signal of the first oxygen bomb detection device 15 is blocked and the signal of the second oxygen bomb detection device 16 is connected, it means that the oxygen bomb cover 13 and the oxygen bomb cylinder 21 are successfully closed.

[0054] It should be noted that the first oxygen bomb detection device 15 at a high position can be arranged at the bottom of the oxygen bomb cylinder 21 after the oxygen bomb cover 13 and the oxygen bomb cylinder 21 are successfully closed, and the second oxygen bomb detection device 16 at a low position is arranged below the first oxygen bomb detection device 15. Therefore, when the oxygen bomb cover 13 and the oxygen bomb cylinder 21 are successfully closed, only the signal of the first oxygen bomb detection device 15 will be blocked, while the signal of the second oxygen bomb detection device 16 can be connected; when the oxygen bomb cover 13 and the oxygen bomb cylinder 21 are not successfully closed, after the oxygen bomb cylinder 21 is separated from the oxygen bomb cylinder rotating device 2, because the oxygen bomb cylinder 21 is not tightened and fixed with the oxygen bomb cover 13, it will fall freely under the action of gravity, so the signals of the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 are both connected; when the oxygen bomb cover 13 and the oxygen bomb cylinder 21 are not completely closed, after the oxygen bomb cylinder 21 is separated from the oxygen bomb cylinder rotating device 2, the oxygen bomb cylinder 21 and the oxygen bomb cover 13 are not completely tightened, the oxygen bomb cylinder 21 will fall, so that the signals of the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 are both blocked.

[0055] During actual use, the structure, size, position, model, etc. of the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 may be determined according to actual conditions and actual needs.

[0056] On the basis of the above-mentioned oxygen bomb automatic opening and closing device, preferably, the oxygen bomb rotating device 2 includes an oxygen bomb air claw 22 for clamping and fixing the oxygen bomb 21, a rotating electric cylinder 23 for driving the oxygen bomb 21 to rotate, and an electric cylinder support frame 24 connected to the rotating electric cylinder 23 for supporting the rotating electric cylinder 23. The oxygen bomb air claw 22 is arranged on the rotating electric cylinder 23, and the electric cylinder support frame 24 is connected to the moving device 33. The control device is respectively connected to the oxygen bomb air claw 22 and the rotating electric cylinder 23, and can control the oxygen bomb air claw 22 to clamp and fix the oxygen bomb 21 and control the rotation process of the rotating electric cylinder 23, so that after the oxygen bomb rotating device 2 fixes the oxygen bomb 21, it drives the oxygen bomb 21 to rotate, so as to facilitate the oxygen bomb 21 and the oxygen bomb cover 13 to be tightened, closed or separated.

[0057] In actual use, the structure, size, position, etc. of the oxygen bomb air claw 22, the rotary electric cylinder 23 and the electric cylinder support frame 24 can be determined according to actual conditions and actual needs.

[0058] Preferably, the oxygen cartridge rotating device 2 includes an electric cylinder supporting elastic member 25 disposed below the rotating electric cylinder 23, and the electric cylinder supporting elastic member 25 is used to provide buffering and tilting freedom in different directions for the opening and closing operations of the oxygen cartridge 21 and the oxygen cartridge cover 13. This is conducive to inserting the oxygen cartridge 21 into the oxygen cartridge cover 13, and can reduce the friction generated by the misalignment between the oxygen cartridge 21 and the oxygen cartridge cover 13 when closing the cover, that is, it can effectively reduce the wear of the oxygen cartridge.

[0059] Preferably, the electric cylinder supporting elastic member 25 can be set as a spring. Of course, the electric cylinder supporting elastic member 25 can also be set as other elastic members according to actual conditions and actual needs during actual use.

[0060] On the basis of the above-mentioned automatic opening and closing device of the oxygen bomb, preferably, the oxygen bomb cylinder lifting device 3 is provided with a first optical slot sensor 32 at a high position and a second optical slot sensor 34 at a low position along the height direction of the track 31, the first optical slot sensor 32 and the second optical slot sensor 34 are used to detect the position signal of the oxygen bomb cylinder 21, the first optical slot sensor 32 and the second optical slot sensor 34 are both connected to the control device to transmit the detection signal to the control device, when the oxygen bomb cylinder 21 is located at the position of the first optical slot sensor 32, the oxygen bomb cylinder 21 contacts the oxygen bomb cover 13, so as to facilitate the opening and closing operations of the oxygen bomb cylinder 21 and the oxygen bomb cover 13.

[0061] Therefore, the control device can receive the position signal of the oxygen bomb 21 in real time, and control the oxygen bomb lifting device 3 in time to make the oxygen bomb 21 and the oxygen bomb cover 13 contact or separate.

[0062] During actual use, the structure, model, position, etc. of the first optical slot sensor 32 and the second optical slot sensor 34 may be determined according to actual conditions and actual needs.

[0063] In addition, it should be noted that when the oxygen bomb automatic cover opening and closing device provided by the present invention is used to perform a cover closing operation, the oxygen bomb cylinder 21 can be placed on the oxygen bomb cylinder air claw 22 by a manipulator, and then the oxygen bomb cover 13 can be placed on the oxygen bomb cover support frame 11 by a manipulator. Subsequently, the control device can control the movement of the driving cylinders 12 to approach each other, so that the oxygen bomb cover retaining plate 14 is closed toward the oxygen bomb cover 13, and the protrusion of the oxygen bomb cover 13 is inserted into the groove of the oxygen bomb cover retaining plate 14.

[0064] Afterwards, the control device can control the oxygen cartridge air claw 22 to clamp the oxygen cartridge 21, and control the oxygen cartridge lifting device 3 to rise from the position of the second optical slot sensor 34 to the position of the first optical slot sensor 32, so as to insert the oxygen cartridge 21 into the oxygen cartridge cover 13. Finally, the control device can control the oxygen cartridge rotating device 2 to rotate so that the oxygen cartridge 21 and the oxygen cartridge cover 13 can be tightened and fixed, and can control the oxygen cartridge lifting device 3 to descend to end the cover closing operation.

[0065] Among them, the signals transmitted to the control device by the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 can form a judgment logic for whether the cover is closed successfully or not. If the signal of the first oxygen bomb detection device 15 is blocked and the signal of the second oxygen bomb detection device 16 is connected, it means that the cover closing operation is successful; if the signals of the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 are both blocked or connected, it means that the cover closing operation fails.

[0066] Preferably, when the oxygen cartridge rotating device 2 is controlled to rotate so that the oxygen cartridge 21 and the oxygen cartridge cover 13 can be tightened and fixed, the rotating electric cylinder 23 can be first reversed by 130° to align the threads of the oxygen cartridge 21 and the oxygen cartridge cover 13, and then the rotating electric cylinder 23 is rotated forward again to tighten and fix the oxygen cartridge 21 and the oxygen cartridge cover 13 until the rotating electric cylinder 23 is overloaded, and then the rotating electric cylinder 23 is reversed by 10° to complete the cover closing operation, which can effectively ensure the tightening effect between the oxygen cartridge 21 and the oxygen cartridge cover 13. Of course, the rotation operation can also be determined according to actual conditions and actual needs during actual use.

[0067] When the oxygen bomb automatic cover opening and closing device provided by the present invention is used to perform a cover opening operation, the oxygen bomb in the closed state can be placed on the oxygen bomb cover support frame 11 by a manipulator, and the control device can control the movement of the driving cylinders 12 to move closer to each other, so that the oxygen bomb cover retaining plate 14 is closed toward the oxygen bomb cover 13, and the protrusion of the oxygen bomb cover 13 is inserted into the groove of the oxygen bomb cover retaining plate 14.

[0068] Afterwards, the control device can control the oxygen cartridge lifting device 3 to rise from the position of the second optical slot sensor 34 to the position of the first optical slot sensor 32, and then control the oxygen cartridge air claw 22 to clamp the oxygen cartridge 21, so as to separate the oxygen cartridge 21 and the oxygen cartridge cover 13. Finally, the control device can control the oxygen cartridge rotating device 2 to rotate so that the oxygen cartridge 21 and the oxygen cartridge cover 13 can be loosened and separated, and can control the oxygen cartridge lifting device 3 to descend to end the cover opening operation.

[0069] Among them, the signals transmitted to the control device by the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 can form a judgment logic for whether the cover is opened successfully or not. If one of the first oxygen bomb detection device 15 or the second oxygen bomb detection device 16 is blocked by the signal, it means that the cover opening operation has failed; if the first oxygen bomb detection device 15 and the second oxygen bomb detection device 16 are both connected to the signal, it means that the cover opening operation is successful.

[0070] Preferably, when the oxygen cartridge rotating device 2 is controlled to rotate so that the oxygen cartridge 21 and the oxygen cartridge cover 13 can be loosened and separated, the rotating electric cylinder 23 can be reversed three and a half turns to completely separate the threads of the oxygen cartridge 21 and the oxygen cartridge cover 13, so that the separation effect between the oxygen cartridge 21 and the oxygen cartridge cover 13 can be effectively ensured. Of course, the rotation operation can also be determined according to actual conditions and actual needs during actual use.

[0071] The oxygen bomb automatic cover opening and closing device provided by the present invention can cooperate with a manipulator device to automatically complete the oxygen bomb cover opening, sample laying and cover closing actions of the calorimeter experiment, thereby effectively reducing labor costs and reducing the labor intensity of operators. Moreover, the device is provided with a first oxygen bomb detection device 15 and a second oxygen bomb detection device 16, which can then determine whether the cover opening and cover closing operations are successful. In addition, the device has a simple structure, is easy to operate, and has high working efficiency, and can be promoted for use.

[0072] In addition to the above-mentioned oxygen bomb automatic cover opening and closing device, the present invention also provides an oxygen bomb suitable for the oxygen bomb automatic cover opening and closing device disclosed in the above-mentioned embodiment, the oxygen bomb comprises an oxygen bomb cylinder 21 and an oxygen bomb cover 13, and the oxygen bomb cover 13 is provided with a protrusion to facilitate the oxygen bomb cover support device 1 to fix the oxygen bomb cover 13.

[0073] It should be further explained that the oxygen bomb here refers to an oxygen bomb of a two-body structure, which is different from an oxygen bomb of a three-body structure. The oxygen bomb of the three-body structure includes an oxygen bomb cylinder 21, a pressure ring and an oxygen bomb cover 13. The oxygen bomb provided by the present invention only includes an oxygen bomb cylinder 21 and an oxygen bomb cover 13, and the oxygen bomb cover 13 is provided with a protrusion to facilitate the oxygen bomb cover support device 1 to fix the oxygen bomb cover 13, which is more suitable for mechanical automatic opening and closing operations.

[0074] Preferably, the bottom of the oxygen bomb 21 is provided with vertical knurling, which is used to increase the friction between the oxygen bomb 21 and the oxygen bomb rotating device 2, so that the oxygen bomb rotating device 2 can better fix the oxygen bomb 21.
