Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Refer to Figure 1, An embodiment provided by the present utility model: A nitrogen replacement skid, including a base 1, four groups of rollers are arrayed at the bottom of the base 1, which is convenient for the staff to move the base 1. A square telescopic rod 2 is fixedly connected to the top of the base 1, and four groups of square telescopic rods 2 are arrayed. Handles are provided on two groups of square telescopic rods 2 near the left side, which is convenient for the staff to hold by hand. The top end of the square telescopic rod 2 is fixedly connected to a frame 3. The frame 3 is composed of a square frame and a cross-shaped plate, which can simultaneously limit the transportation of four groups of nitrogen cylinders. A lifting component 4 is arranged on the base 1. Through the lifting component 4, it is convenient to adjust the height position of the frame 3 to adapt to nitrogen cylinders of different heights. A stabilizing component 5 is arranged on the frame 3. Through the stabilizing component 5, the nitrogen cylinders in the frame 3 are clamped and fixed, thereby improving the stability of the nitrogen cylinders during transportation.
[0034] Refer to Figures 1 - 3 , The lifting component 4 includes support rods 41, and two groups of support rods 41 are symmetrically distributed. The bottom end of the support rod 41 is hinged with a slider 42, and two groups of sliders 42 are symmetrically distributed. A clamping block 44 is elastically connected to the inner wall of the slider 42 through a spring 43. Through the elastic force of the spring 43, the clamping block 44 always maintains the clamping effect with the card slot without external force, thereby limiting the slider 42 and keeping the frame 3 fixed. A chute is opened at the front end of the top of the base 1, and two groups of chutes are symmetrically distributed. A card slot is opened at the bottom of the inner wall of the chute, and multiple groups of card slots are provided. Through the clamping effect of multiple groups of card slots and the clamping block 44 at different positions, different position limiting effects are achieved on the slider 42. The left end of the bottom of the base 1 is hinged with a circular telescopic rod 46. Through the rotation effect of the circular telescopic rod 46, the square plate 45 is driven to move vertically. The right end of the circular telescopic rod 46 is hinged with a square plate 45. The front end of the top of the square plate 45 is fixedly connected with multiple groups of top blocks 48. The positions of multiple groups of top blocks 48 correspond to the positions of multiple groups of card slots. A cylindrical rod 49 is slidably connected to the inner wall of the square plate 45. Through the sliding effect of the square plate 45, the top block 48 is driven to move vertically, so that the top block 48 is inserted into or disengaged from the card slot.
[0035] Refer to Figure 4 and Figure 5 , The stabilizing component 5 includes four groups of arc-shaped plates A51, which are symmetrically distributed. Grooves are opened on the inner walls of the square telescopic rods 2, and two groups of sliding rods 53 are slidably connected to the inner walls of the grooves. Through the sliding effect of the sliding rods 53, two groups of arc-shaped plates B52 can be driven to move simultaneously. Arc-shaped plates B52 are slidably connected to the inner walls of the grooves, and four groups of arc-shaped plates B52 are symmetrically distributed. Through the sliding effect of the four groups of arc-shaped plates B52, the four groups of nitrogen cylinders can be clamped and fixed respectively with the four groups of arc-shaped plates A51. Threaded rods 54 are threadedly connected to the inner walls of the sliding rods 53, and four groups of threaded rods 54 are symmetrically distributed.
[0036] Reference Figure 1 and Figure 3 , the top end of the support rod 41 is hinged to the bottom of the frame 3. Through the movement effect of the frame 3, the support rod 41 can be driven to move. The slider 42 is slidably connected to the inner wall of the chute. Through the movement effect of the support rod 41, the slider 42 can be driven to slide. The bottom of the base 1 is elastically connected to the top of the square plate 45 through the return spring 410. Through the elastic force of the return spring 410, the square plate 45 always moves downward without external force, so that the top block 48 always maintains the disconnection of the plug-in effect with the card slot.
[0037] Reference Figure 2 , one end of the spring 43 is fixedly connected to the inner wall of the slider 42, and the other end of the spring 43 is fixedly connected to the top of the clamping block 44. Through the fixing effect of the spring 43, the clamping block 44 is kept fixed to prevent the clamping block 44 from falling off. The outer wall of the clamping block 44 is slidably connected to the inner wall of the slider 42. Through the sliding effect of the clamping block 44, the clamping block 44 is engaged or disengaged with the card slot. The outer wall of the clamping block 44 is engaged with the inner wall of the card slot. The left end of the circular telescopic rod 46 is fixedly connected with a pedal 47. By the staff stepping on the pedal 47, the circular telescopic rod 46 can be driven to rotate. The top of the cylindrical rod 49 is fixedly connected to the bottom of the base 1. Through the fixing effect of the cylindrical rod 49, the cylindrical rod 49 is prevented from falling off. The outer wall of the top block 48 is inserted into the inner wall of the card slot. Through the insertion effect of the top block 48 and the card slot, the top block 48 presses the clamping block 44, so that the clamping block 44 is disengaged from the card slot.
[0038] Reference Figure 4 and Figure 5 , the outer wall of the arc plate A51 is fixedly connected to the inner wall of the square telescopic rod 2. Through the fixing effect of the arc plate A51, the arc plate A51 is prevented from falling off. The right end of the threaded rod 54 is rotatably connected to the left inner wall of the arc plate B52. By rotating the threaded rod 54, the arc plate B52 can be driven to move slightly. The right side of the frame 3 is fixedly connected with a bidirectional electric telescopic rod 55. By starting the bidirectional electric telescopic rod 55, the two groups of sliding rods 53 can be driven to approach or move away from each other. The output end of the bidirectional electric telescopic rod 55 is fixedly connected to the outer wall of the sliding rod 53.
[0039] Reference Figure 3 , one end of the return spring 410 is fixedly connected to the bottom of the base 1, and the other end of the return spring 410 is fixedly connected to the top of the square plate 45. Through the fixing effect of the return spring 410, the return spring 410 is kept fixed to prevent the return spring 410 from falling off.
[0040] Working principle: When the staff needs to transport and replace the nitrogen cylinder, the staff inserts the nitrogen cylinder between the arc plate A51 and the arc plate B52, so that the bottom of the nitrogen cylinder is located on the base 1. Then, the bidirectional electric telescopic rod 55 is started. The bidirectional electric telescopic rod 55 drives two groups of sliding rods 53 to approach each other at the same time. The two groups of sliding rods 53 drive four groups of arc plates B52 to slide along the inner wall of the groove and approach the arc plate A51 at the same time. The nitrogen cylinder is clamped and fixed by the arc plate A51 and the arc plate B52 to improve the stability of the nitrogen cylinder during transportation.
[0041] When the size of a group of nitrogen cylinders is smaller or larger, the staff screws the corresponding threaded rod 54. The threaded rod 54 drives the corresponding arc plate B52 to move, so as to adjust the position of the arc plate B52 separately, so as to clamp and fix nitrogen cylinders of different sizes. When the height of the nitrogen cylinder to be transported and replaced is relatively short, the staff steps on the pedal 47, so that the circular telescopic rod 46 drives the square plate 45 to move upward, so that multiple top blocks 48 are inserted into multiple card slots at the same time, thereby squeezing the clamping block 44, so that the clamping block 44 releases the clamping effect with the card slot, and at the same time releases the limiting effect on the slider 42.
[0042] Subsequently, the staff holds the frame 3 and adjusts the height position of the frame 3. When the frame 3 moves, it drives the support rod 41 to move, so that the slider 42 slides along the inner wall of the chute. When adjusted to the appropriate position, the pedal 47 is released, so that the square plate 45 moves downward under the elastic force of the return spring 410. At the same time, multiple top blocks 48 release the clamping effect with multiple card slots, so that the clamping block 44 is clamped with the card slot under the elastic force of the spring 43, and at the same time limits the slider 42, so that the support rod 41 and the frame 3 are fixed, completing the adjustment of the height position of the frame 3.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
