[0039] In order to make the technical problems, technical schemes and beneficial effects of the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0042] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0043] It should be noted that when disassembling the breathing type safety valve 30, the valve body 33 is rotated out of the valve cover 31, and at the same time, the suction valve 34 needs to be pressed downward to be separated from the valve body base 35, so as to eliminate the upward elastic force of the spring 32 on the valve body 33, and further reduce the resistance between the valve body 33 and the threaded pair of the valve cover 31, thereby avoiding damage to the threaded pair. The existing manual disassembly method requires the worker to press the suction valve 34 while rotating the valve body 33, which is difficult to operate and low in efficiency, and it takes more people to cooperate to disassemble one breathing type safety valve 30, which is very wasteful of manpower and time cost. Based on the above problems, the utility model provides an automatic disassembly and installation equipment for the breathing type safety valve, which replaces the traditional manual disassembly method and can automatically complete the two actions of pressing the suction valve 34 and rotating out the valve body 33, without manual intervention during the disassembly process, thereby realizing the full automation of the breathing type safety valve 30.

[0044] Please refer to Figures 1 to 5 , the automatic disassembly and installation equipment for the breathing type safety valve provided by the utility model will be described. The automatic disassembly and installation equipment for the breathing type safety valve comprises a workbench 40, a suction valve pressing assembly 10 and a valve body rotating-out assembly 20, the suction valve pressing assembly 10 and the valve body rotating-out assembly 20 are arranged above the workbench 40, the pressing end of the suction valve pressing assembly 10 is pressed against the suction valve 34 to press the suction valve 34 downward, and the valve body rotating-out assembly 20 is connected with the valve body base 35 to rotate the valve body base 35 out of or into the valve cover 31.

[0045] Specifically, the workbench 40 is suitable for limiting the valve cover 31 of the breathing type safety valve 30. The suction valve pressing assembly 10 is arranged above the workbench 40 and comprises a pressing driving mechanism 11 and a pressing piece 12 connected with the pressing driving mechanism 11, wherein one end of the pressing piece 12 is suitable for being connected with the pressing driving mechanism 11 and the other end is suitable for being pressed against the suction valve 34 arranged above the suction valve 34 and being lifted relative to the breathing type safety valve 30. The valve body rotating-out assembly 20 comprises a rotating piece 21 connected with the driving end of the pressing driving mechanism 11, a connecting rod 22 arranged on the rotating piece 21 and corresponding to the assembly hole on the valve body base 35 of the breathing type safety valve 30, and a rotating driving mechanism 23 connected with the driving end of the pressing driving mechanism 11. When the suction valve pressing assembly 10 presses the suction valve 34, the valve body rotating-out assembly 20 rotates the valve body 33 out of or into the valve cover 31. It should be noted that when disassembled, the breathing type safety valve 30 is inverted on the workbench 40, and the valve body base 35 faces upward.

[0046] In the embodiment of the present application, the valve body 33 is rotated out by rotating the valve body out assembly 20, and the suction valve 34 is pressed by the suction valve pressing assembly 10 at the same time, so that the elastic force of the spring 32 on the valve body 33 is removed. Both the pressing and rotating actions are automatically completed by the equipment without manual intervention, the full automation of the disassembly process of the respiratory safety valve 30 is realized, the disassembly difficulty of the respiratory safety valve 30 is greatly reduced, the labor cost is saved, and the disassembly efficiency is improved. In addition, the present equipment can also be used to realize the automatic installation of the respiratory safety valve. When the pressing piece 12 presses the suction valve 34, the rotating piece 21 is controlled to reverse by the rotating driving mechanism 11, and the valve body 33 is rotated into the valve cover 31.

[0047] In an alternative embodiment, please refer to Figure 3 The pressing driving mechanism 11 comprises a pressing driving cylinder 111 and a pressing rod 112 in sealing sliding fit with the pressing driving cylinder 111. The rotating piece 21 is connected with the bottom end of the pressing rod 112. The pressing piece 12 abuts against the rotating piece 21, and the pressing piece 12 is static relative to the suction valve 34 under the action of the pressing force and the bottom friction force when the pressing rod 112 drives the rotating piece 21 to rotate.

[0048] Preferably, the pressing piece 12 is a cylindrical structure with an upper opening and a lower opening, which is made of metal material. Since the cylindrical structure is adopted, the contact area between the top end of the pressing piece 12 and the driving end of the pressing driving mechanism 11 is small, and the metal surface is relatively smooth. In addition, the pressure of the spring 32 on the suction valve 34 and the pressing piece 12 is very large, so the pressing piece 12 will not rotate and will not damage the suction valve 34.

[0049] In the above embodiment, the pressing driving cylinder 111 is preferably an air cylinder, the top end of the pressing rod 112 is assembled with or integrally formed with the piston rod of the air cylinder, and the bottom end of the pressing rod 112 is assembled with the rotating piece 21. During disassembly, the pressing driving cylinder 111 drives the pressing rod 112 to descend, and then drives the rotating piece 21 at the bottom of the pressing rod 112 to press on the pressing piece 12.

[0050] On the basis of the existing air cylinder structure, the present embodiment provides a novel air cylinder structure with an internal spring 32. The air cylinder comprises a cylinder body, a piston, a piston rod and a return spring. The piston is movably arranged inside the cylinder body and is lifted along the cylinder body under the action of air pressure. The piston rod is fixedly connected to the bottom of the piston. The return spring is arranged between the piston and the bottom of the cylinder body. The bottom of the return spring is fixed to the cylinder body, and the top of the return spring abuts against the piston. It should be noted that the piston can rotate relative to the return spring and the cylinder body.

[0051] In the embodiment of the present application, the return spring is arranged at the bottom of the piston to ensure the return of the piston and avoid the piston from rising out of position due to the influence of air pressure.

[0052] In an alternative embodiment, please refer to Figures 1 to 3The rotating member 21 is in a strip structure. In the above embodiment, the rotating member 21 and the connecting rod 22 can be connected in various ways. For example, the connecting rod 22 is connected to the assembly hole on the valve body base 35 and abuts against the rotating pushing end of the rotating member 21. Alternatively, a through slot corresponding to the assembly hole is arranged on the rotating member 21, and the connecting rod 22 passes through the through slot and is connected to the assembly hole on the valve body base 35.

[0053] In some possible embodiments, referring to Figure 3 The rotating driving mechanism 23 includes a motor 231, a transmission sprocket 232 arranged on the output shaft of the motor 231, and a transmission gear set. The power input end of the transmission gear set is assembled with the driven wheel of the transmission sprocket 232, and the power output end is in transmission connection with the pressing rod 112. When the device is used to realize the installation function, the motor 231 is reversed to drive the rotating member 21 to be reversed.

[0054] The present embodiment provides an optional power transmission structure. The pressing rod 112 is provided with a spline suitable for engaging with the transmission gear set, and the spline extends along the length direction of the pressing rod 112.

[0055] In some possible embodiments, referring to Figure 4 and Figure 5 The upper end surface of the workbench 40 is provided with a valve cover limiting groove 41. The side wall of the valve cover limiting groove 41 is provided with a first rectangular groove 42 suitable for accommodating the protrusion at the bottom of the valve cover 31. When disassembled, the valve cover 31 is placed in the valve cover limiting groove 41, and the protrusion at the bottom of the valve cover 31 is clamped in the first rectangular groove 42 to limit the valve cover 31, so that the valve cover 31 is prevented from rotating together with the valve body 33.

[0056] In another possible embodiment, the upper end surface of the workbench 40 is provided with a valve cover 31 limiting through groove. The side wall of the valve cover 31 limiting through groove is provided with a second rectangular groove suitable for accommodating the protrusion at the bottom of the valve cover 31. The bottom of the valve cover 31 limiting through groove is provided with a jacking device suitable for jacking out the disassembled valve cover 31 from the valve cover 31 limiting through groove.

[0057] In the embodiment of the present application, the jacking device can be used to jack out the disassembled valve cover 31, solving the problem that the valve cover 31 is difficult to take out from the groove, and facilitating the staff to take the valve cover 31.

[0058] Optionally, the jacking device is a cylinder vertically fixed below the valve cover 31 limiting through groove. A frame is arranged below the valve cover 31 limiting through groove. The fixed end of the cylinder is fixed on the frame. During disassembly, the lifting end of the cylinder extends into the valve cover 31 limiting through groove and is located at the bottom thereof to support the breathing type safety valve 30. After disassembly, the lifting end of the cylinder jacks up the valve cover 31 from the valve cover 31 limiting through groove.

[0059] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
