Description

Technical Field

[0001] This invention relates to the field of cylinder fixing technology, specifically to a cylinder fixing device with gravity self-locking and tilt locking functions. It is suitable for fixing high-pressure, flammable, explosive, or toxic and harmful gas cylinders in industrial production, medical, fire protection, scientific research and other fields, and can effectively prevent safety accidents caused by cylinder tipping or sliding. Background Technology

[0002] In many fields such as industrial production, laboratories, and medical care, steel cylinders are commonly used containers for gas storage. The safety of their fixation during use is of paramount importance. Steel cylinders usually contain high-pressure gas. If they are not securely fixed, they are prone to shaking, tipping, or even falling, which can lead to safety accidents such as gas leaks and explosions. Therefore, steel cylinder fixing devices are key equipment to ensure the safe use of steel cylinders.

[0003] Currently, there are various cylinder fixing devices on the market. Their core function is to achieve stable clamping of the cylinder and prevent it from shifting during storage or use, so as to meet the needs of safe production and use. However, most existing cylinder fixing devices rely on an additional power source (such as electricity or hydraulics) to drive the clamping components, which not only consumes energy but also increases the cost of use and maintenance difficulty. Some devices also use manual clamping, requiring manual adjustment of the clamping components to fix the cylinder, which is cumbersome and inefficient. Furthermore, manual operation is prone to problems such as insufficient or excessive clamping force, which affects the stability of the fixation and may damage the cylinder. In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a steel cylinder fixing device with gravity self-locking and tilt locking functions that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A cylinder fixing device with gravity self-locking and tilt locking functions includes a base and a fixing frame fixedly connected to the base, and further includes: a positioning rod slidably connected to the fixing frame; two connecting seats symmetrically fixedly connected to both sides of the fixing frame, each connecting seat having a rotating shaft rotatably connected to it, a clamping rod fixedly sleeved on the rotating shaft, tilting push blocks fixedly connected to both sides of the positioning rod, and the end of the clamping rod near the positioning rod in close contact with the inclined slope of the tilting push block; and a torsion spring coaxially sleeved on the outer wall of the rotating shaft. One end of the torsion spring is fixedly connected to the inner wall of the connecting seat, and the other end is fixedly connected to the end of the rotating shaft away from the connecting seat. The gravity drive unit is correspondingly set on the base. When the cylinder is placed vertically on the upper surface of the base, the cylinder's own weight triggers the gravity drive unit to start operation, driving the positioning rod to move laterally along the fixed frame. During the movement of the positioning rod, through the sloping squeezing action of the inclined push blocks on both sides, the clamping rods on both sides are synchronously driven to rotate in opposite directions around the rotating axis until the side wall of the positioning rod and the inner side of the clamping rods on both sides are in close contact with the outer wall of the cylinder, thus completing the clamping and fixing of the cylinder.

[0006] As a further improvement of this application, a drive cylinder is fixedly connected to the fixed frame, and a piston disc is slidably connected inside the drive cylinder. The drive cylinder also includes a connecting rod, one end of which is fixedly connected to the piston disc, and the other end of which passes through the drive cylinder and is fixedly connected to the positioning rod. A spring is disposed inside the drive cylinder, one end of which is fixedly connected to the piston disc, and the other end of which is fixedly connected to the inner wall of the drive cylinder. An air supply pipe is connected at one end to the drive cylinder and at the other end to an external air source. Gas is introduced into the drive cylinder through the external air source, driving the piston disc to move axially along the drive cylinder, and synchronously driving the positioning rod to move up and down through the connecting rod, thereby adjusting the clamping state of the clamping rod.

[0007] As a further improvement of this application, it also includes an exhaust pipe, on which a solenoid valve for controlling the opening and closing of the pipeline is provided, and one end of the exhaust pipe is connected to the side wall of the drive cylinder for discharging the gas inside the drive cylinder. This, together with a spring, enables the piston disc and positioning rod to be reset, thereby releasing the clamping rod from clamping and fixing the cylinder.

[0008] As a further improvement of this application, the gravity drive unit includes a piston cylinder and a sliding plug. The piston cylinder is fixedly connected to the lower side of the base, and the sliding plug is slidably connected to the inside of the piston cylinder, with the outer wall of the sliding plug tightly fitted to the inner wall of the piston cylinder. A pressing rod is fixedly connected to the center of the upper side of the sliding plug. The upper end of the pressing rod extends vertically upward through the top wall of the piston cylinder and the base, with its top end located above the base, for bearing the weight of the gas cylinder. The end of the gas supply pipe away from the drive cylinder is connected to the side wall of the piston cylinder, and the piston cylinder is fixedly connected to a gas replenishment pipe.

[0009] As another improvement of this application, the piston cylinder is provided with a spring three, one end of which is fixedly connected to the sliding plug and the other end is fixedly connected to the inner wall of the piston cylinder.

[0010] As a further improvement to this application, a guide sleeve is fixedly connected between the two connecting seats, the positioning rod is slidably engaged with the guide sleeve, a sliding cavity is provided inside the guide sleeve, an adsorption block is slidably connected inside the sliding cavity, a locking pin is fixedly connected to the adsorption block, a plurality of locking holes adapted to the locking pin are equidistantly provided on the positioning rod, an electromagnet is provided inside the sliding cavity, and the electromagnet is correspondingly engaged with the adsorption block.

[0011] Secondly, a detection cylinder is fixedly connected to the fixed frame, and a sliding disk is slidably connected inside the detection cylinder. The side wall of the sliding disk and the inner wall of the detection cylinder are both provided with a conductive ring. The conductive ring is used to control the on and off of the electromagnet. A spring is provided inside the detection cylinder. One end of the spring is fixedly connected to the sliding disk, and the other end is fixedly connected to the inner wall of the detection cylinder. The detection cylinder is connected to the drive cylinder through a branch pipe.

[0012] Preferably, a pull rod is fixedly connected to the adsorption block, and a lifting handle is fixedly connected to one end of the pull rod that passes through the sliding cavity. The pull rod is used to pull the adsorption block to slide upward and reset in the sliding cavity, so that the locking pin disengages from the locking hole and releases the locking of the positioning rod.

[0013] Furthermore, a second conductive ring is provided at the lower end of the locking pin and inside the lock hole, and a warning light is installed on the fixing frame. When the two second conductive rings come into contact, the warning light is triggered to turn on.

[0014] Furthermore, rollers are rotatably connected to both ends of the clamping rod and the end of the positioning rod away from the fixed frame.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: This invention utilizes the weight of the gas cylinder itself to trigger the clamping action, eliminating the need for additional power input and achieving a gravity self-locking function. This saves energy and is easy to operate, solving the problem of traditional gas cylinder fixing devices requiring manual clamping and being inefficient. The symmetrically arranged clamping rods on both sides, together with the positioning rods, can fix the gas cylinder from three directions, providing strong clamping stability and effectively preventing the gas cylinder from shaking. At the same time, the torsion spring allows the clamping rods to automatically open after the gas cylinder is removed and the gravity drive unit resets, making it easier to insert the gas cylinder next time and improving the convenience of use. The adjustable elasticity of the torsion spring and the slope adjustment margin of the tilting push block allow the device to flexibly adapt to gas cylinders of different diameters without the need to replace the clamping parts, effectively improving the versatility of the device and reducing equipment investment costs.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a cylinder fixing device with gravity self-locking and tilt locking functions includes a base 1 and a fixing frame 101 fixedly connected to the base 1, and also includes a positioning rod 2 slidably connected to the fixing frame 101. Two connecting seats 201 are symmetrically fixedly connected to both sides of the fixed frame 101. A rotating shaft 203 is rotatably connected to each of the two connecting seats 201. A clamping rod 202 is fixedly sleeved on the rotating shaft 203. Inclined push blocks 205 are fixedly connected to both sides of the positioning rod 2. The end of the clamping rod 202 near the positioning rod 2 is in close contact with the inclined slope of the inclined push block 205. The torsion spring 206 is coaxially sleeved on the outer wall of the rotating shaft 203. One end of the torsion spring 206 is fixedly connected to the inner wall of the connecting seat 201, and the other end is fixedly connected to the end of the rotating shaft 203 away from the connecting seat 201. It should be noted that in the initial state, the torsion spring 206 is in a naturally extended state, which drives the clamping rod 202 to be in an open state, making it easier to put the gas cylinder in. The gravity drive unit is correspondingly set on the base 1. When the gas cylinder is placed vertically on the upper surface of the base 1, the gravity of the gas cylinder triggers the gravity drive unit to start operation, driving the positioning rod 2 to move laterally along the fixing frame 101. During the movement of the positioning rod 2, through the slope squeezing action of the inclined push blocks 205 on both sides, the clamping rods 202 on both sides are synchronously driven to rotate in opposite directions around the rotation axis 203 until the side wall of the positioning rod 2 and the inner side of the clamping rods 202 on both sides are in close contact with the outer wall of the gas cylinder, thus completing the clamping and fixing of the gas cylinder.

[0020] Initially, the torsion spring 206 is in its natural extended state, causing the clamping rods 202 on both sides to open around the rotation axis 203. The positioning rod 2 is in the initial position of the fixing frame 101. At this time, the gas cylinder can be placed vertically on the upper surface of the base 1, with the bottom of the gas cylinder aligned with the gravity drive unit. When the gas cylinder is completely and stably placed, the weight of the gas cylinder acts on the gravity drive unit, triggering the gravity drive unit to start operation and drive the positioning rod 2 to move laterally along the fixing frame 101 (towards the gas cylinder). During the movement of positioning rod 2, the inclined push blocks 205 on both sides move synchronously. The inclined slope of the inclined push block 205 and the inclined surface of the end of clamping rod 202 exert a squeezing effect, forcing the clamping rods 202 on both sides to overcome the elastic force of torsion spring 206 and rotate in opposite directions around the rotation axis 203. Since the elastic force of torsion spring 206 can be adapted and adjusted according to actual needs, and the slope design of inclined push block 205 has a certain adjustment margin, the moving distance of positioning rod 2 will change when placing steel cylinders of different diameters. For steel cylinders with larger diameters, the positioning... When the movement distance of rod 2 is short, the squeezing amplitude of the inclined push block 205 on the clamping rod 202 is small, and the rotation angle of the clamping rod 202 is small, a tight fit can be achieved. For cylinders with smaller diameters, the movement distance of positioning rod 2 is longer, the squeezing amplitude of the inclined push block 205 on the clamping rod 202 is larger, and the rotation angle of the clamping rod 202 is larger, and a tight fit can still be achieved until the side wall of positioning rod 2 and the inner side of both clamping rods 202 are in tight contact with the outer wall of the cylinder. At this time, the gravity drive unit stops operating, completing the clamping and fixing of cylinders of different diameters. In this process, the clamping action is triggered by the weight of the gas cylinder itself, without the need for additional power input, achieving a gravity self-locking function. This saves energy and is easy to operate, solving the problem of traditional gas cylinder fixing devices requiring manual clamping and being inefficient. The clamping rods 202 on both sides are symmetrically arranged, and together with the clamping of the positioning rod 2, the gas cylinder can be fixed from three directions, providing strong clamping stability and effectively preventing the gas cylinder from shaking. At the same time, the torsion spring 206 can automatically open the clamping rods 202 after the gas cylinder is removed and the gravity drive unit is reset, making it easier to put the gas cylinder in next time and improving the convenience of use. The adjustable elasticity of the torsion spring 206 and the slope adjustment margin of the tilting push block 205 allow the device to flexibly adapt to gas cylinders of different diameters without the need to replace clamping components, effectively improving the versatility of the device, reducing equipment investment costs, and making it suitable for fixing different specifications of gas cylinders in various scenarios.

[0021] like Figures 5-8 As shown, a drive cylinder 3 is fixedly connected to the fixed frame 101, a piston disc 301 is slidably connected inside the drive cylinder 3, and a connecting rod 303 is also included. One end of the connecting rod is fixedly connected to the piston disc 301, and the other end passes through the drive cylinder 3 and is fixedly connected to the positioning rod 2. The spring 302, which is installed inside the drive cylinder 3, has one end fixedly connected to the piston disc 301 and the other end fixedly connected to the inner wall of the drive cylinder 3. The air supply pipe 304 is a high-pressure hose, one end of which is connected to the drive cylinder 3, and the other end is used to connect to an external air source such as an air pump. Gas is introduced into the drive cylinder 3 through the external air source, driving the piston disc 301 to move axially along the drive cylinder 3, and synchronously driving the positioning rod 2 to move up and down through the connecting rod 303, thereby adjusting the clamping state of the clamping rod 202. A valve is provided on the air supply pipe 304 to control the on / off of the air source.

[0022] In the initial state, spring 302 is in a naturally extended state, piston disc 301 is located at the end of drive cylinder 3 away from spring 302, connecting rod 303 drives positioning rod 2 to the initial position, and clamping rods 202 on both sides are in an open state under the action of torsion spring 206. When it is necessary to clamp the cylinder, in addition to using the gravity drive unit mentioned above to drive positioning rod 2 to move laterally, high-pressure gas can also be introduced into gas supply pipe 304 through external gas source. The gas enters the interior of drive cylinder 3 through gas supply pipe 304 and generates thrust on piston disc 301. When the gas thrust is greater than the elastic force of spring 302, it pushes the piston disc 301 to move axially along the drive cylinder 3. The piston disc 301 drives the connecting rod 303 to move synchronously, which in turn drives the positioning rod 2 to move laterally along the fixing frame 101. The subsequent clamping process is the same as the above until the cylinder clamping and fixing is completed. When it is necessary to adjust the clamping state of the clamping rod 202 (such as loosening or adjusting the clamping force), the gas pressure of the gas supply pipe 304 can be adjusted to change the moving distance of the piston disc 301, thereby adjusting the position of the positioning rod 2 and achieving precise adjustment of the clamping force. This structure combines pneumatic and gravity drives, enabling automatic self-locking based on the weight of the cylinder and active adjustment via an external air source. It adapts to cylinders of different weights and specifications, enhancing the versatility of the device. The spring 302 provides a reverse elastic force during pneumatic drive to assist in adjusting the clamping force, and also resets the piston disc 301 and positioning rod 2 when the air supply stops, facilitating cylinder removal.

[0023] like Figures 5-8 As shown, it also includes an exhaust pipe 305, on which a solenoid valve is installed to control the opening and closing of the pipeline. One end of the exhaust pipe 305 is connected to the side wall of the drive cylinder 3 to discharge the gas inside the drive cylinder 3. In conjunction with the spring 302, the piston disc 301 and the positioning rod 2 are reset, thereby releasing the clamping rod 202 from clamping and fixing the cylinder. It should be noted that the solenoid valve is an electromagnetic reversing valve, which is connected to an external control switch through a wire. It can realize remote or manual control of the opening and closing of the exhaust pipe 305. The solenoid valve has good sealing performance to ensure that the gas inside the drive cylinder 3 will not leak from the exhaust pipe 305.

[0024] When the gas cylinder is used up and needs to be released from clamping, close the valve on the gas supply pipe 304 to stop the gas from being supplied to the drive cylinder 3. Then, activate the solenoid valve through the control switch to put the exhaust pipe 305 in the conducting state. At this time, the high-pressure gas inside the drive cylinder 3 is discharged through the exhaust pipe 305, and the gas pressure gradually decreases. When the gas thrust is less than the elastic force of spring 302, spring 302 begins to reset, pushing the piston disc 301 to move in the opposite direction along the axis of the drive cylinder 3. The piston disc 301 drives the connecting rod 303 and the positioning rod 2 to reset synchronously. The positioning rod 2 moves away from the gas cylinder, and the inclined push blocks 205 on both sides no longer squeeze the clamping rod 202. At this time, the torsion spring 206 resets under its own elastic force, driving the clamping rods 202 on both sides to rotate in the opposite direction around the rotation axis 203 and return to the open state, thereby releasing the clamping and fixing of the gas cylinder. The gas cylinder can then be removed from the base 1. After removing the gas cylinder, close the solenoid valve and cut off the exhaust pipe 305. The device returns to its initial state and waits for the next use. The combination of exhaust pipe 305 and solenoid valve enables rapid discharge of gas from inside drive cylinder 3, allowing piston disc 301 and positioning rod 2 to quickly reset, significantly improving the efficiency of clamp release and solving the problems of slow reset and cumbersome operation in traditional devices. The solenoid valve allows for remote control without the need for close-range manual operation, improving operational safety. At the same time, the combination of spring 302 and exhaust pipe 305 automates clamping and unclamping, reducing manual intervention and improving work efficiency.

[0025] like Figures 1-5 As shown, the gravity drive unit includes a piston cylinder 7 and a sliding plug 701. The piston cylinder 7 is fixedly connected to the lower side of the base 1, and the sliding plug 701 is slidably connected to the inside of the piston cylinder 7. The outer wall of the sliding plug 701 is tightly fitted to the inner wall of the piston cylinder 7. A pressing rod 703 is fixedly connected to the center of the upper side of the sliding plug 701. The upper end of the pressing rod 703 extends vertically upward through the top wall of the piston cylinder 7 and the base 1. Its top end is located above the base 1, and a circular pressure plate (not shown in the figure) is provided at the top end to facilitate the bearing of the weight of the cylinder and prevent the bottom of the cylinder from directly pressing the pressing rod 703 and causing damage. The end of the air supply pipe 304 away from the drive cylinder 3 is connected to the side wall of the piston cylinder 7. The piston cylinder 7 is fixedly connected to the air supply pipe 704. A one-way valve is provided on the air supply pipe 704 to ensure that outside air can only enter the inside of the piston cylinder 7 and cannot be discharged from the air supply pipe 704, ensuring that the sliding plug 701 can move smoothly downward.

[0026] In the initial state, the sliding plug 701 is located at the top of the piston cylinder 7, the top of the pressing rod 703 extends out of the base 1, the one-way valve of the air supply pipe 704 is in the open state, the piston cylinder 7 is filled with air, the valve on the air supply pipe 304 is in the closed state, the spring 302 in the drive cylinder 3 is in the naturally compressed state, the positioning rod 2 is in the initial position, and the clamping rod 202 is in the open state. When the gas cylinder is placed vertically on the base 1, the bottom of the gas cylinder presses on the pressure plate of the pressing rod 703. The weight of the gas cylinder itself is transmitted to the pressing rod 703 through the pressure plate, which drives the sliding plug 701 to slide down along the inner wall of the piston cylinder 7. During the downward movement of the sliding plug 701, the air inside the piston cylinder 7 is squeezed, which increases the gas pressure inside the piston cylinder 7. At this time, the one-way valve on the gas supply pipe 704 is closed to prevent gas from being discharged from the gas supply pipe 704. When the gas pressure inside the piston cylinder 7 reaches the preset value, the valve on the gas supply pipe 304 is opened, and the high-pressure gas enters the drive cylinder 3 through the gas supply pipe 304, pushing the piston plate 301 to move, which in turn drives the positioning rod 2 to move laterally, triggering the clamping rod 202 to clamp and fix the gas cylinder. The subsequent process is the same as the above. This gravity-driven unit has a simple structure and low cost. It requires no additional power source and relies entirely on the weight of the cylinder to achieve gas compression and drive, thus automating the clamping action and saving energy. The pressure plate at the top of the pressing rod 703 increases the contact area with the bottom of the cylinder, preventing damage caused by uneven force on the bottom of the cylinder. At the same time, it ensures that the weight of the cylinder can be accurately transmitted to the sliding plug 701. The cooperation between the air supply pipe 704 and the one-way valve ensures that the sliding plug 701 can smoothly compress gas when it moves down. When the cylinder is removed and the sliding plug 701 is reset, outside air can enter the piston cylinder 7 through the air supply pipe 704, so that the sliding plug 701 can be quickly reset, improving the recycling efficiency of the device.

[0027] like Figure 2 As shown, a spring 702 is provided inside the piston cylinder 7. One end of the spring 702 is fixedly connected to the sliding plug 701, and the other end is fixedly connected to the inner wall of the piston cylinder 7. In the initial state, the spring 702 is in a naturally extended state, supporting the sliding plug 701 at the top of the piston cylinder 7. The pressing rod 703 remains extended. The elastic force of the spring 702 is less than the minimum weight of the cylinder, ensuring that the cylinder can be placed smoothly to compress the spring 702 and drive the sliding plug 701 to move down.

[0028] In the initial state, spring 3 702 is in a naturally extended state, the supporting sliding plug 701 is located at the top of the piston cylinder 7, the pressing rod 703 extends out of the base 1, the one-way valve of the gas supply pipe 704 is open, and the valve of the gas supply pipe 304 is closed. When the gas cylinder is placed on the pressing rod 703, the weight of the gas cylinder is greater than the elastic force of spring 3 702, pushing the sliding plug 701 to slide downward, spring 3 702 is compressed, and at the same time, the gas inside the piston cylinder 7 is squeezed, the gas pressure increases, the one-way valve closes, and then gas is supplied to the drive cylinder 3 through the gas supply pipe 304 to complete the gas cylinder clamping. The process is the same as the above.

[0029] When the gas cylinder is removed, the pressure of the gas cylinder on the pressing rod 703 disappears. At this time, the spring 702 returns to its original position under its own elastic force, pushing the sliding plug 701 to slide upward along the inner wall of the piston cylinder 7 and return to its initial position. The pressing rod 703 extends synchronously, and at the same time, a negative pressure is formed inside the piston cylinder 7. The one-way valve on the air supply pipe 704 is opened, and outside air enters the piston cylinder 7 to replenish the internal gas and prepare for the next use.

[0030] The spring 702 serves both a supporting and resetting function. On one hand, it supports the sliding stopper 701 in its initial position when the cylinder is not in place, ensuring that the pressing rod 703 extends normally for easy cylinder placement. On the other hand, after the cylinder is removed, it can quickly reset the sliding stopper 701 and the pressing rod 703 without manual intervention, improving the automation level and recycling efficiency of the device. At the same time, the buffering effect of the spring 702 can reduce the impact force on the sliding stopper 701 and piston cylinder 7 when the cylinder is placed, preventing damage to components due to impact and extending the service life of the device.

[0031] like Figure 7 , Figure 9 As shown, a guide sleeve is fixedly connected between the two connecting seats 201. The positioning rod 2 is slidably engaged with the guide sleeve. A sliding cavity 4 is provided inside the guide sleeve. An adsorption block 402 is slidably connected inside the sliding cavity 4. The adsorption block 402 is made of ferromagnetic material. A locking pin 403 is fixedly connected to the adsorption block 402. Multiple locking holes 404 that are adapted to the locking pin 403 are equidistantly provided on the positioning rod 2. An electromagnet 401 is provided inside the sliding cavity 4. The electromagnet 401 is correspondingly engaged with the adsorption block 402. The electromagnet 401 is connected to an external power supply and a control switch through a wire.

[0032] Once the gas cylinder is clamped in place, the positioning rod 2 stops moving. At this time, the power to the electromagnet 401 is turned off, the magnetic force of the electromagnet 401 disappears, and the adsorption block 402 slides downward under its own gravity, causing the locking pin 403 to move downward synchronously, so that the lower end of the locking pin 403 is in close contact with the surface of the positioning rod 2. During long-term use of the device, if gas leakage occurs inside the drive cylinder 3, or if the piston disc 301 ages and the seal fails, causing gas on one side of the piston disc 301 to leak to the other side, or if the piston disc 301 shifts, the piston disc 301 will... The connecting rod 303 drives the positioning rod 2 to move offset. During the movement of the positioning rod 2, the locking pin 403 will accurately insert into the corresponding locking hole 404 on the positioning rod 2, instantly locking the positioning rod 2 and forcibly preventing the positioning rod 2 from continuing to move. This avoids problems such as loose clamping, cylinder tipping, and clamping failure caused by failure of the driving component, and improves the safety and stability of cylinder fixing. At the same time, the multiple locking holes 404 evenly distributed on the positioning rod 2 can be adapted to cylinders of different diameters and can achieve stable locking in different clamping positions, improving the versatility and adaptability of the device.

[0033] like Figure 7 , Figure 8 , Figure 9 As shown, a detection cylinder 5 is fixedly connected to the fixed frame 101, and a sliding disk 501 is slidably connected inside the detection cylinder 5. Both the side wall of the sliding disk 501 and the inner wall of the detection cylinder 5 are provided with conductive rings 502. The conductive rings 502 are used to control the on and off of the electromagnet 401. A spring 504 is provided inside the detection cylinder 5. One end of the spring 504 is fixedly connected to the sliding disk 501, and the other end is fixedly connected to the inner wall of the detection cylinder 5. The detection cylinder 5 is connected to the drive cylinder 3 through a branch pipe 503.

[0034] In the initial state, spring 2 504 is in a naturally extended state, sliding disk 501 is located at the end of detection cylinder 5, and two conductive rings 1 502 are in contact, so that the control circuit of electromagnet 401 is turned on and electromagnet 401 is in an energized state, generating magnetic force to attract the adsorption block 402 to slide upward along the sliding cavity 4, driving the locking pin 403 to disengage from the initial locking hole 404 of positioning rod 2, releasing the initial locking of positioning rod 2 in advance, preparing for the smooth movement of positioning rod 2 after the gas cylinder is put in, avoiding the initial locking of positioning rod 2 from affecting subsequent clamping actions, and improving the continuity of operation; When the gas cylinder is placed on the base 1, the gravity drive unit is activated, and gas is supplied to the drive cylinder 3 through the gas supply pipe 304. After the gas enters the drive cylinder 3, it generates a thrust on the piston disc 301, which pushes the piston disc 301 to move axially along the drive cylinder 3. The piston disc 301 drives the positioning rod 2 to move laterally through the connecting rod 303, which in turn drives the clamping rods 202 on both sides to rotate in opposite directions, gradually completing the clamping and fixing of the gas cylinder. During this process, the electromagnet 401 is continuously energized, and the locking pin 403 always remains disengaged from the locking hole 404, ensuring that the positioning rod 2 can move smoothly without locking interference, and ensuring smooth and efficient clamping action. Once the gas cylinder is fully clamped in place, the positioning rod 2 is blocked by the gas cylinder and cannot move further. This causes the piston disc 301 to be fixed inside the drive cylinder 3 and unable to move further. At this time, gas continues to be supplied into the drive cylinder 3. The gas inside the drive cylinder 3 cannot push the piston disc 301 to move, causing the gas pressure inside the cylinder to gradually increase. The increased gas pressure is synchronously introduced into the detection cylinder 5 through the branch pipe 503, generating a continuous thrust on the sliding disc 501. When this thrust is greater than the elastic force of the second spring 504, it pushes the sliding disc 501 to move axially along the detection cylinder 5, while compressing the second spring 504, until the two conductive rings 502 separate, the control circuit of the electromagnet 401 is disconnected, the electromagnet 401 is de-energized, and the magnetic force disappears. Subsequently, the adsorption block 402 slides downward under its own gravity, causing the locking pin 403 to move downward synchronously, so that the lower end of the locking pin 403 is in close contact with the surface of the positioning rod 2, preparing for emergency locking in case of possible displacement of the positioning rod 2. This detection structure, in conjunction with the locking structure described above, enables automatic control of the on / off state of electromagnet 401, eliminating the need for manual operation, thus increasing the automation level of the device, reducing human intervention, and lowering the probability of operational errors.

[0035] When the device experiences faults such as gas leakage in the drive cylinder 3 or aging and seal failure of the piston disc 301, the air pressure in the drive cylinder 3 and the detection cylinder 5 will gradually decrease. When the air pressure in the detection cylinder 5 is less than the elastic force of the compressed spring 504, the spring 504 pushes the sliding disc 501 to move axially along the detection cylinder 5 until the two conductive rings 502 contact, so that the electromagnet 401 circuit is connected and the electromagnet 401 is energized. This ensures that when the locking of the positioning rod 2 is released, the electromagnet 401 can attract the adsorption block 402, ensuring that the unlocking action is performed smoothly. This avoids the situation where the electromagnet 401 is not energized and cannot attract the adsorption block 402, which would prevent the locking of the positioning rod 2 from being released smoothly. This ensures that the cylinder removal or device reset operation can still be completed smoothly after the fault occurs.

[0036] like Figure 9 As shown, a pull rod 405 is fixedly connected to the adsorption block 402. A lifting handle is fixedly connected to one end of the pull rod 405 that passes through the sliding cavity 4. The pull rod 405 is used to pull the adsorption block 402 to slide upward and reset in the sliding cavity 4, so that the locking pin 403 disengages from the locking hole 404 and releases the locking of the positioning rod 2.

[0037] When the device experiences malfunctions such as gas leakage in the drive cylinder 3 or aging and seal failure of the piston disc 301, causing the positioning rod 2 to shift, the locking pin 403 inserts into the corresponding locking hole 404 of the positioning rod 2, thus achieving emergency locking of the positioning rod 2. To release this emergency lock, the operator can hold the lifting handle at the top of the pull rod 405 and manually pull the pull rod 405 upwards. The pull rod 405 drives the adsorption block 402 to move smoothly upwards along the sliding cavity 4. Simultaneously, the adsorption block 402 drives the locking pin 403 upwards until the locking pin 403 is completely removed from the locking hole 404, thus completely releasing the emergency lock on the positioning rod 2. At the same time, continue pulling the pull rod 405 until the adsorption block 402 is in close contact with the electromagnet 401, ensuring that the locking pin 403 is always detached from the locking hole 404. This prevents the locking pin 403 from falling back into the locking hole 404 after the lock is released, ensuring that the positioning rod 2 can move normally and smoothly complete the cylinder removal or device reset operation. This avoids work stoppage due to the inability to release the emergency lock and ensures the continuity of work.

[0038] like Figure 1 , Figure 9As shown, conductive rings 6 are provided at the lower end of the locking pin 403 and inside the lock hole 404. A warning light 601 is installed on the fixing bracket 101. The warning light 601 is connected to the two conductive rings 6 through wires to form a conductive circuit. When the two conductive rings 6 are in contact, the circuit is connected and the warning light 601 turns on (emitting red or yellow light). When the two conductive rings 6 are separated, the circuit is broken and the warning light 601 turns off.

[0039] Once the gas cylinder is clamped in place, the positioning rod 2 stops moving, the power supply to the electromagnet 401 is turned off, and the adsorption block 402 slides down under its own gravity, causing the lower end of the locking pin 403 to contact the surface of the positioning rod 2. At this time, the two conductive rings 6 are not in contact, the warning light 601 remains off, indicating that the gas cylinder has been clamped in place but the locking pin 403 has not yet been inserted into the lock hole 404 and is in a waiting-to-lock state. During long-term use of the device, if gas leakage occurs in the drive cylinder 3 or the piston disc 301 ages and its seal fails, causing displacement of the piston disc 301 and moving the positioning rod 2 via the connecting rod 303, the locking pin 403 will precisely insert into the corresponding locking hole 404 during the movement of the positioning rod 2. The two conductive rings 6 will then contact each other again, completing the conductive circuit. The warning light 601 will immediately turn on, not only indicating to the operator that the positioning rod 2 has completed emergency locking to prevent clamping failure, but also promptly reminding the operator that the drive component has malfunctioned and needs maintenance, preventing the malfunction from escalating and causing safety hazards such as the cylinder tipping over. When it is necessary to release the clamp, the electromagnet 401 is energized, the locking pin 403 disengages from the locking hole 404, the conductive rings 6 separate, and the warning light 601 turns off, indicating that the positioning rod 2 has been unlocked and the cylinder can be removed. After the cylinder is removed, the locking pin 403 resets and inserts into the initial locking hole 404, the conductive rings 6 contact, and the warning light 601 turns on again, indicating that the device has returned to its initial locking state and is ready for the next use.

[0040] like Figure 5 As shown, rollers 204 are rotatably connected to both ends of the clamping rod 202 and the end of the positioning rod 2 away from the fixed frame 101.

[0041] In the initial state, the clamping rod 202 is in the open state and the roller 204 is in the natural state. When the gas cylinder is placed on the base 1, the gravity drive unit is activated. When the positioning rod 2 moves laterally, the roller 204 on the positioning rod 2 first contacts the outer wall of the gas cylinder. At the same time, the clamping rod 202 rotates in opposite directions around the rotation axis 203. The rollers 204 at both ends of the clamping rod 202 contact the slope of the inclined push block 205 and the outer wall of the gas cylinder, respectively.

[0042] During the continuous movement of the positioning rod 2, the slope of the inclined push block 205 rolls into contact with the roller 204 at one end of the clamping rod 202, converting sliding friction into rolling friction, reducing frictional loss between the two, making the rotation of the clamping rod 202 smoother, and preventing damage to the inclined push block 205 and the end of the clamping rod 202 due to friction. The roller 204 at the other end of the clamping rod 202 rolls into contact with the outer wall of the gas cylinder, and the roller 204 on the positioning rod 2 also rolls into contact with the outer wall of the gas cylinder. This not only reduces frictional damage to the outer wall of the gas cylinder during clamping and protects the surface coating of the gas cylinder, but also makes the movement of the positioning rod 2 and the clamping rod 202 smoother, ensuring stable and efficient clamping action.

[0043] When the gas cylinder shakes slightly, the roller 204 can rotate slightly with the cylinder's movement, which acts as a buffer to prevent rigid collisions between the gas cylinder and the clamping rod 202 and the positioning rod 2, further protecting the gas cylinder and improving the stability of the clamping.
