[0025] Combine the following Figure 1-Figure 5 The utility model is described in detail.

[0026] Example

[0027] A hydrogen storage gas cylinder valve installation device includes a bracket 22 and a transfer roller 21 rotatably arranged on the bracket 22 for moving the gas cylinder 4, a mounting frame 1 is arranged on the outer side of the bracket 22, a mounting plate 11 is arranged on the mounting frame 1, a first telescopic device 5 is arranged on the mounting plate 11 along the axial direction of the gas cylinder 4, the telescopic end of the first telescopic device 5 is connected to a motor 7, the output shaft of the motor 7 is connected to a torque sensor 8, the torque sensor 8 is connected to a valve head 9, the valve head 9 includes a shell 901, a mounting groove 903 is arranged in the shell 901, and a protective liner 904 for clamping the bottle valve 10 is clamped in the mounting groove 903.

[0028] The transfer roller 21 moves the gas cylinder 4. After moving into place, the first telescopic device 5 drives the valve head 9 to move forward and approach the bottle mouth of the gas cylinder 4, and then the motor 7 drives the valve head 9 to rotate so as to tighten the bottle valve 10 on the gas cylinder 4. The torque sensor 8 can monitor the magnitude of the torque to ensure that the bottle valve 10 is installed in place while avoiding damage to the bottle valve 10 due to excessive torque; the protective liner 904 is arranged in the valve head 9 to contact the bottle valve 10, so as to avoid damage to the bottle valve 10 during rotation; the transfer roller 21 can rotate in the opposite direction after the bottle valve 10 is installed, so as to withdraw the gas cylinder 4 from the installation equipment and prepare for the next installation operation.

[0029] The torque sensor 8 is conventional technology, and the motor 7 and the torque sensor 8 are connected to a controller (not shown in the figure). After the torque sensor 8 detects that the torque reaches the set value, the controller controls the motor 7 to stop working. A card slot 905 adapted to the shape of the bottle valve 10 is set in the protective liner 904, so that the bottle valve 10 can be driven to rotate and screwed on the gas cylinder 4. The protective liner 904 is made of a polymer composite material. The polymer composite material structure is a nylon composite material reinforced with 30% glass fiber. It is designed as a whole, and the thickness of the stress-bearing part is 5-8mm, which increases durability. The polymer composite material liner serves the purpose of transmitting torque, protecting the bottle valve 10 and protecting special structures such as PRD.

[0030] At present, there are many kinds of bottle valves, and the appearance of the bottle valves is different. The tooling involved is also different, and different protective liners 904 can be installed. The outer wall of the protective liner 904 is provided with a limit groove 906, and the shell 901 is threaded with a limit screw 902 extending into the limit groove 906. The protective liner 904 prevents the protective liner 904 from moving out of the valve head 9 through the limit screw 902 and the limit groove 906. At the same time, it is also convenient to disassemble the protective liner 904 and replace the protective liner 904 of different thicknesses, so as to meet the installation requirements of different bottle valves.

[0031] The mounting frame 1 is vertically provided with a second telescopic device 2 located above the transfer roller 21. The telescopic end of the second telescopic device 2 is connected to a V-shaped pressing plate 3. The transfer roller 21 is provided with a V-shaped groove 27 along the circumferential direction.

[0032] The transfer roller 21 is connected to a drive motor (not shown in the figure), and the drive motor and the second telescopic device 2 are both connected to the controller; after the gas cylinder 4 reaches the specified position, the drive motor stops rotating, and then controls the second telescopic device 2 to drive the V-shaped pressure plate 3 to move downward, so that the V-shaped pressure plate 3 cooperates with the transfer roller 21 with the V-shaped groove 27 to fix the position of the gas cylinder 4, thereby ensuring the stability of the installation of the bottle valve 10.

[0033] A rubber pad 28 is provided inside the V-shaped pressing plate 3. The rubber pad 28 can prevent the gas cylinder 4 from sliding in the axial direction and rotating in the circumferential direction. A pressure sensor can also be provided inside the V-shaped pressing plate 3 to detect the pressing force of the V-shaped pressing plate 3 on the gas cylinder 4 to prevent the gas cylinder 4 from being crushed.

[0034] The mounting frame 1 is vertically provided with a first slide groove 6, the mounting plate 11 is slidably connected to the first slide groove 6, the bottom of the mounting plate 11 is rotatably connected with a vertically provided screw rod 13, and the screw rod 13 is connected with a screw rod lifter 12 fixedly provided on the mounting frame 1. The screw rod lifter 12 drives the screw rod 13 to move up and down, thereby driving the first telescopic device 5 to adjust its position up and down, so as to adapt to the installation operation of gas cylinders 4 of different sizes.

[0035] One end of the bracket 22 close to the first telescopic device 5 is connected to a support plate 20, and a third telescopic device 18 is vertically arranged below the support plate 20. The telescopic end of the third telescopic device 18 is connected to a baffle 19 which vertically movably penetrates the support plate 20 and is used to block the movement of the gas cylinder 4. A groove 25 is arranged on the side of the baffle 19 close to the gas cylinder 4, and a movable plate 24 protruding from the surface of the baffle 19 is movably arranged in the groove 25. The inner side of the movable plate 24 is connected to a spring 23 fixedly arranged in the groove 25, and a pressure sensor 26 cooperating with the movable plate 24 is arranged in the groove 25.

[0036] The first telescopic device 5 and the pressure sensor 26 are both connected to the controller; the third telescopic device 18 extends the baffle 19 and blocks the movement of the gas cylinder 4. After the gas cylinder 4 moves to abut the movable plate 24, the movable plate 24 will move into the groove 25 and eventually squeeze the pressure sensor 26. After the pressure sensor 26 senses the pressure, the controller controls the drive motor of the transfer roller 21 to stop rotating, so that the gas cylinder 4 reaches the specified position.

[0037] The support plate 20 is provided with a second slide groove 17 along the length direction of the first telescopic device 5, and a slider 16 is slidably connected in the second slide groove 17. A telescopic rod 14 connected to the motor 7 is vertically arranged on the slider 16, and a fixing knob 15 for limiting the telescopic extension of the telescopic rod 14 is arranged on the telescopic rod 14. The telescopic rod 14 can support the motor 7 to prevent the excessive weight of the motor 7 from causing deformation of the telescopic end of the first telescopic device 5. The telescopic rod 14 can freely adjust its height to adapt to the change in the height of the first telescopic device 5, and finally the telescopic extension of the telescopic rod 14 is fixed by the fixing knob 15 to keep the length of the telescopic rod 14 unchanged.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
