Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 4 , the present invention provides a technical solution: an acetylene gas cylinder filling rack, including an L-shaped operating table 18 fixedly installed on one side of the base 22 and having an L-shaped cross-section. An arc-shaped opening 25 for placing the gas cylinder 20 is provided on one side of the operating table 18. The top of the base 22 is fixedly connected with a U-shaped limit block 21 with an opening facing away from the L-shaped operating table 18. When the gas cylinder 20 is placed on the top of the base 22, one side of the gas cylinder 20 is clamped in the arc-shaped opening 25. At this time, the bottom of the gas cylinder 20 is located in the U-shaped limit block 21, which plays a role in fixing the gas cylinder 20 and preventing the bottom of the gas cylinder 20 from shaking. A limiting device for clamping the gas cylinder 20 is fixedly connected to the bottom of the L-shaped operating table 18. As Figure 2 shown, the limiting device includes connecting seats 23 symmetrically connected to the bottom of the L-shaped operating table 18. Fourth electric telescopic rods 24 are fixedly connected to the adjacent sides of the two connecting seats 23. The ends of the fourth electric telescopic rods 24 are fixedly connected with arc-shaped clamping plates 27. In order to increase the friction between the arc-shaped clamping plate 27 and the gas cylinder 20, anti-slip lines are provided on its inner wall ( Figure 2 indicated by the arrow A in), and the arc-shaped clamping plate 27 contacts the surface of the gas cylinder 20 under the push of the fourth electric telescopic rod 24, which can stably clamp the gas cylinder 20 and further improve the stability of the placement of the gas cylinder 20. At the same time, the top of the arc-shaped clamping plate 27 is fixedly connected with a fourth guide rod 19. The end of the fourth guide rod 19 passes through the connecting seat 23. Under the guiding action of the fourth guide rod 19, the stable sliding of the fourth guide rod 19 can be ensured.

[0021] One side of the top of the L-shaped operating table 18 is fixedly connected with an L-shaped bracket 1. One end of the bottom of the L-shaped bracket 1 is connected with an inflation device through a lifting device, and the inflation device is located directly above the gas cylinder 20. The inflation device includes a U-shaped mounting seat 13 that is rotatably connected to the bottom of the lifting device and has an opening downward, as Figure 1 shown. 2 As shown in the figure, the lifting device includes a first electric telescopic rod 4 connected to the bottom of the L-shaped bracket 1. The bottom of the first electric telescopic rod 4 is rotatably connected to the top of the U-shaped mounting seat 13 through a rotating seat 5. One side of the top of the U-shaped mounting seat 13 is vertically connected with a first guide rod 2. An arc-shaped through groove 3 coaxial with the first electric telescopic rod 4 is opened on the L-shaped bracket 1. The top of the first guide rod 2 penetrates through the arc-shaped through groove 3. In order to ensure the stability of the first guide rod 2, a limiting sleeve 17 with an I-shaped cross-section is slidably connected in the arc-shaped through groove 3. The first guide rod 2 penetrates through the limiting sleeve 17. When the U-shaped mounting seat 13 is rotated and adjusted, the limiting sleeve 17 can be driven to slide along the arc-shaped through groove 3, so as to ensure the horizontal rotation adjustment of the U-shaped mounting seat 13. At the same time, the first guide rod 2 slides up and down in the limiting sleeve 17, which can ensure the stable up and down sliding adjustment of the U-shaped mounting seat 13 and improve the practicability of the device.

[0022] A third electric telescopic rod 12 is horizontally connected to one inner wall of the U-shaped mounting seat 13. The end of the third electric telescopic rod 12 is fixedly connected with a clamping seat 11. An inflation head 10 is fixedly connected in the clamping seat 11. The inflation head 10 is of an L-shaped structure. The bottom of the inflation head 10 is connected with an air inlet pipe, and a solenoid valve 26 for controlling gas is connected to the air inlet pipe. In actual use, the U-shaped mounting seat 13 is controlled to lift and adjust, driving the inflation head 10 to move to the bottleneck of the gas cylinder 20 and connecting the inflation head 10 with the inflation pipe on the gas cylinder 20, then the inflation operation can be carried out. At the same time, a third guide rod 16 is fixedly connected to one side of the clamping seat 11. The other end of the third guide rod 16 penetrates through the side wall of the U-shaped mounting seat 13, ensuring the stable horizontal movement of the inflation head 10 and further facilitating the sealed connection of the inflation head 10 with the inflation pipe, as Figure 3 shown. 4As shown in the figure, in order to facilitate the installation and removal of the inflating head 10, a limiting groove 30 is formed on one side of the clamping seat 11 close to the gas cylinder 20. The limiting groove 30 penetrates through the bottom of the clamping seat 11. The inflating head 10 is located in the limiting groove 30, and one side of the limiting groove 30 is fastened by a locking bolt 31. The end of the locking bolt 31 is cooperatively connected with a locking nut 9. The outer wall of the locking nut 9 is symmetrically connected with arc-shaped side plates 29 extending outwards. By rotating the arc-shaped side plates 29 to drive the locking nut 9 to rotate on the locking bolt 31, the clamping force of the clamping seat 11 on the inflating head 10 can be controlled. After removing the locking bolt 31 and the locking nut 9, it is convenient to remove the inflating head 10 from the bottom of the limiting groove 30, thereby facilitating the maintenance and replacement of the inflating head 10.

[0023] On one inner wall of the U-shaped mounting seat 13, a second electric telescopic rod 6 is horizontally connected. The end of the second electric telescopic rod 6 is fixedly connected with an arc-shaped clamping block 8. After the inflating head 10 is connected to the inflating pipe, the second electric telescopic rod 6 pushes the arc-shaped clamping block 8 to abut against the outer wall of the valve body at the top of the gas cylinder 20, which can further improve the clamping force between the inflating head 10 and the inflating pipe, thereby effectively avoiding leakage. As Figure 4 shown, on the inner wall of the arc-shaped clamping block 8, a non-slip rubber pad is fixedly connected ( Figure 4 as indicated by the arrow B in the figure), which can increase the friction force between the arc-shaped clamping block 8 and the outer wall of the valve body. The top of the arc-shaped clamping block 8 is fixedly connected with a mounting seat 28. On the side wall of the mounting seat 28, a second guiding rod 7 is horizontally connected. The other end of the second guiding rod 7 penetrates through the side wall of the U-shaped mounting seat 13. At the same time, a control box 14 is fixedly connected to one side of the U-shaped mounting seat 13. A controller is fixedly connected in the control box 14. The first electric telescopic rod 4, the second electric telescopic rod 6, the third electric telescopic rod 12, the fourth electric telescopic rod 24, and the solenoid valve 26 are all connected to the controller through wires. In order to facilitate the operator to rotate and adjust the U-shaped mounting seat 13, U-shaped rods 15 are symmetrically connected to both side walls of the U-shaped mounting seat 13, which is convenient for hand holding.

[0024] In summary, when using this acetylene gas cylinder filling rack, place the bottom of the gas cylinder 20 in the U-shaped limiting block 21, and make the middle part of the gas cylinder 20 located in the arc-shaped opening 25. Control the fourth electric telescopic rod 24 to push the arc-shaped clamping plate 27 to clamp the outer wall of the gas cylinder 20, and control the first electric telescopic rod 4 to drive the U-shaped mounting seat 13 to descend, so that the inflating head 10 and the inflating pipe are on the same plane. Hold the U-shaped rod 15 and drive the U-shaped mounting seat 13 to rotate to make the inflating head 10 and the inflating pipe on the same straight line, and control the third electric telescopic rod 12 and the second electric telescopic rod 6 to rotate simultaneously, then the inflating head 10 and the inflating pipe can be hermetically connected. Then, the solenoid valve 26 can be used to control the entry of gas, and thus the inflation operation can be carried out.
