Description
Technical Field
[0001] The utility model relates to the field of large gas cylinder weighing, in particular to a transition device used for large gas cylinder transfer weighing. Background Art
[0002] Gas cylinders are containers for storing compressed gas and are widely used in the chemical, medical, safety, and life industries. Gas is stored in high pressure in the cylinders. Since these cylinders need to withstand the high pressure of the gas in the cylinders, they are usually made of high-strength materials such as stainless steel and aluminum alloy. When the cylinders need to be filled with gas, they need to be moved to a scale to monitor their quality. The quality of the gas in the cylinder can be obtained by weighing the difference in mass before and after filling.
[0003] At present, the weighing procedure for large gas cylinders is mostly to place them on a scale for weighing. The traditional method requires digging a groove on the ground surface where the scale can be embedded, and then placing the scale in the groove. The weighing table of the scale is basically at the same level as the ground. When the large gas cylinder needs to be weighed, a special trolley is used to carry it to the vicinity of the groove embedded in the scale. After tightening the bottle cap, the bottle shoulder is moved by hand at a certain tilt angle to rotate the bottom of the bottle and move the gas cylinder to the center of the scale. The upright gas cylinder is weighed after it is stable. After the weighing is completed, the gas cylinder is removed from the scale in the same way. In the long run, it is easy to cause wear and tear on the weighing table of the scale. If the scale is not embedded in the ground environment in advance, the horizontal height of the platform is higher than the ground. When the large gas cylinder needs to be weighed, it is very difficult to lift the large gas cylinder to the platform surface. In actual production, taking large cylinders filled with high-purity gases as an example, the most common ones on the market are 40L cylindrical standard cylinders, which generally weigh more than 50kg. Therefore, the labor intensity of moving large cylinders during the weighing process is relatively high. Summary of the invention

The bottom column 21 is vertically arranged on the base 1, and the first transmission shaft 23 is arranged in the bottom column 21. The output end of the first motor 22 and the first transmission shaft 23 are connected by a track to drive the first transmission shaft 23 to rotate longitudinally. One end of the support column 24 movably passes through the top wall of the bottom column 21 and is threaded on the top of the first transmission shaft 23. The first transmission shaft 23 rotates to drive the support column 24 to move vertically. The support arm 25 is fixed on the support column 24, and two through grooves 251 are provided along the length direction of the support arm 25, and slide grooves 252 are provided on the outer sides of the two through grooves 251; a scale 26 is provided at the lower end of the bottom column 21.
[0023] The transverse driving mechanism 3 includes a second motor 31, a second transmission shaft 32 and a sliding rod 33. The second motor 31 and the second transmission shaft 32 are installed on the support arm 25 and are located between the two through grooves 251. The output end of the second motor 31 and the second transmission shaft 32 are connected by a track to drive the second transmission shaft 32 to rotate transversely. A slider 321 is screwed on the second transmission shaft 32. The rotation of the second transmission shaft 32 can drive the slider 321 to move on the second transmission shaft 32. The sliding rod 33 is fixed on the slider 321, and limit blocks 331 are respectively provided at both ends of the sliding rod 33. The limit blocks 331 are slidably arranged in the sliding groove 252, so that the sliding rod 33 can maintain a horizontal state when sliding; preferably, the number of the slider 321 and the sliding rod 33 are two respectively, and both are screwed on the second transmission shaft 32.
[0024] A connecting rod 41 is provided on the top of the mobile frame 4, and the upper end of the connecting rod 41 is penetrated by the through groove 251 and fixedly connected to the sliding rod 33. A through hole 42 is provided on the bottom wall of the mobile frame 4, and an entrance 43 is provided on the side wall. A railing 44 is movably provided on the entrance 43, and one end of the railing 44 is movably connected to the side wall of the mobile frame 4, and the other end is provided with a buckle (not shown). The staff puts the large gas cylinder 200 into the mobile frame 4 from the entrance 43, and clamps the buckle at the other end of the railing 44 on the side wall of the mobile frame 4 to prevent the large gas cylinder 200 from tipping over. The diameter of the large gas cylinder 200 is larger than the diameter of the through hole 42.
[0025] The weighing device 5 is disposed on one side of the base 1 , and includes a balance 51 and a cylindrical weighing auxiliary block 52 placed on the balance 51 . The diameter of the weighing auxiliary block 52 is smaller than the diameter of the through hole 42 .
[0026] The control device 6 is arranged at the upper end of the base column 21, and controls the start and stop of the first motor 22 and the second motor 31. A first proximity sensor 61 is provided on the support column 24 and corresponds to the position of the sliding rod 33. A connecting piece 261 is slidably provided on the scale 26 perpendicularly. The connecting piece 261 can slide up and down on the scale. A second proximity sensor 62 is provided on the connecting piece 261. The first proximity sensor 61 and the second proximity sensor 62 are both connected to the control device 6.
[0027] Working principle: When it is necessary to weigh the large gas cylinder 200, move the transition device 100 to the horizontal ground, and then fix the transition device 100 to the ground through the feet 12, and place the balance 51 on the ground on one side of the base of the transition device 100, and below the support arm 25, and place the weighing auxiliary block 52 directly above the balance 51. According to the size of the balance 51, the height of the weighing auxiliary block 52 can be roughly obtained from the scale 26 at the lower end of the base column 21, and the connecting piece 261 can be slid to about half the height of the weighing auxiliary block 52. By inputting the corresponding parameters on the control device 6, the vertical movement range of the support column 24 and the horizontal movement range of the slide bar 33 can be set.
[0028] Before preparing for weighing, the second motor 31 drives the second transmission shaft 32 to rotate and move the mobile frame 4 to the outer end of the support arm 25, and the large gas bottle 200 to be weighed is transported to the front of the mobile frame 4. The first motor 22 is started and the first transmission shaft 23 is controlled to rotate through the control device 6, so that the support column 24 starts to move downward into the bottom column 21, and the mobile frame 4 also descends. When the bottom wall of the mobile frame 4 touches the ground, the first motor 22 is turned off.
[0029] Open the railing 44 at the entrance 43 of the mobile frame 4, move the large gas cylinder 200 into the mobile frame 4 by rotating the bottle body, and try to align the center line of the large gas cylinder 200 with the center of the through hole 42 of the mobile frame 4, and after the large gas cylinder 200 is upright and stabilized, the hook at one end of the railing 44 is clamped at the entrance 43 of the mobile frame 4 to prevent the large gas cylinder 200 from tipping over during weighing. At this time, the first motor 22 is turned on by the control device 6 to drive the support column 24 to move upward. When the horizontal height of the bottom wall of the mobile frame 4 is about 10 cm higher than the weighing auxiliary block 52, the first motor 22 is automatically turned off, and the second motor 31 is turned on to drive the second transmission shaft 32 to rotate. The rotation of the second transmission shaft 32 drives the slider 321 to move, thereby making the slide bar 33 move horizontally along the inner end of the support arm 25, so that the mobile frame 4 also moves horizontally along the inner end of the support arm 25. When the first proximity sensor 61 senses the slide bar 33, the second motor 31 is automatically turned off. At this time, the axes of the large gas bottle 200, the mobile frame 4 and the weighing auxiliary block 52 are basically located on the same vertical line. Then the first motor 22 is automatically turned on, driving the support column 24 to move vertically downward, and driving the mobile frame 4 to continue to slowly descend. At this time, the weighing auxiliary block 52 will pass through the through hole 42 on the bottom wall of the mobile frame 4 to contact the bottom of the large gas bottle 200 and lift the large gas bottle 200. When the mobile frame 4 continues to descend until it senses the second proximity sensor 62, the control device 6 controls the first motor 22 to automatically turn off, and the mobile frame 4 stops descending. At this time, the large gas bottle 200 can be weighed or gas filled through the balance 51.
[0030] When the weighing operation of the large gas cylinder 200 is completed, the first motor 22 is started through the control device 6. At this time, the mobile frame 4 will move with the rise of the support column 24. The rise of the mobile frame 4 will lift the large gas cylinder 200. At this time, the bottom of the large gas cylinder 200 will be separated from the weighing auxiliary block 52. When the mobile frame 4 rises to a certain height, the first motor 22 will automatically turn off and the second motor 31 will turn on. The mobile frame 4 will move horizontally to the outer end of the support arm 25 along with the slider 321, and then the second motor 31 will be turned off, and the first motor 22 will be turned on immediately. The mobile frame 4 will drop vertically to touch the ground, and the first motor 22 will stop. At this time, the large gas cylinder 200 that has been weighed can be taken out.
[0031] The utility model can facilitate the movement and weighing of the large gas cylinder 200 by setting a transition device 100; can be used to control the longitudinal and lateral movement of the mobile frame 4 by setting a longitudinal drive mechanism 2 and a transverse drive mechanism 3; can be used to weigh the large gas cylinder 200 by setting a weighing device 5; can be used to place the large gas cylinder 200 by setting a mobile frame 4, and move the large gas cylinder 200 to the weighing device 5 for weighing; can be used to control the start and stop of the longitudinal drive mechanism 2 and the transverse drive mechanism 3 by setting a control device 6. The utility model is a transition device for transferring and weighing large gas cylinders with a simple structure and convenient operation. The device avoids pre-destruction of the surface and can also greatly reduce the cost of manpower handling. At the same time, the large gas cylinder does not directly contact the balance during the weighing process, which can greatly reduce the wear of the balance weighing table and prevent equipment damage.
