These problems not only affect work efficiency but may also pose safety hazards to personnel and equipment. Therefore, we propose a specialty gas cylinder transfer device to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a special gas cylinder transfer device, which aims to solve the problems of existing special gas cylinder transfer devices such as insecure clamping, inconvenient adjustment, and poor stability.

[0004] To solve the above technical problems, the present invention provides a special gas cylinder transfer device, including a base, a clamping mechanism inside the base, an adjustment mechanism on one side of the upper surface of the base, a linkage mechanism at one end of the adjustment mechanism, and a clamping mechanism on the outer surface of the linkage mechanism.

[0005] The clamping mechanism includes guide rods fixed at the four corners of the inner bottom wall of the base. A support plate is slidably connected to the top of the outer surface of the guide rod. A fixing block is fixedly connected to one side of the upper surface of the support plate. A connecting rod is hinged to the outer surface of the fixing block. A slider is rotatably connected to one end of the connecting rod. A guide rail is slidably connected inside the slider. The guide rail is fixedly connected to the base. A first bracket is fixedly connected to the upper surface of the slider. A first clamping plate is fixedly connected to one end of the first bracket. A first rubber pad is fixedly connected to the inner side of the first clamping plate.

[0006] Preferably, a damper is fixedly connected to the middle of the lower surface of the pallet, and a spring is sleeved on the bottom of the outer surface of the guide rod.

[0007] Preferably, the adjustment mechanism includes a column fixed to one side of the upper surface of the base, a sleeve column slidably connected to the outer surface of the column, and a lead screw rotatably connected inside the sleeve column, the lead screw passing through the column and rotatably connected thereto.

[0008] Preferably, the linkage mechanism includes a fixed box fixed to one end of the column, a rotating rod rotatably connected to the inner side of the fixed box near the lead screw, and a rocker arm fixedly connected to one end of the rotating rod.

[0009] Preferably, a first bevel gear is fixedly connected to one side of the outer surface of the rotating rod, and a second bevel gear is meshed with the outer surface of the first bevel gear, and the second bevel gear is fixedly connected to the lead screw.

[0010] Preferably, a worm is fixedly connected to the other side of the outer surface of the rotating rod, and a worm wheel is meshed with the outer surface of the worm.

[0011] Preferably, a first support rod is fixedly connected inside the worm gear, a first gear is fixedly connected to the top of the outer surface of the first support rod, a second gear is meshed with the outer surface of the first gear, and a second support rod is fixedly connected inside the second gear.

[0012] Preferably, the clamping mechanism includes a second bracket fixed to the middle of the outer surfaces of the first support rod and the second support rod, a second clamping plate fixedly connected to one end of the second bracket, and a second rubber pad fixedly connected to the inner side of the second clamping plate.

[0013] Preferably, self-locking casters are fixedly connected to both sides of the lower surface of the base, and a support column is fixedly connected to the side of the lower surface of the base away from the self-locking casters.

[0014] Preferably, a push rod is fixedly connected to the edge of the upper surface of the base, and a reinforcing rod is fixedly connected to the top of the outer surface of the push rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The clamping mechanism of the present invention allows the support plate to move downward under the weight of the special gas cylinder itself. Through the hinge of the fixed block and the connecting rod, the slider slides on the surface of the guide rail and is adjusted horizontally according to the diameter of the gas cylinder, making the clamping action more flexible and adaptable to gas cylinders of different diameters. The first clamping plate contacts the gas cylinder through the first rubber pad and applies clamping force. The gravity self-locking mechanism can automatically lock the clamping state after clamping the gas cylinder, preventing the clamping from loosening due to accidental vibration or external force, which greatly improves the reliability of clamping. At the same time, no additional operation steps are required, which improves work efficiency.

[0017] 2. The sleeve of the present invention slides on the column and achieves lifting action through cooperation with the lead screw. The user can make fine adjustments according to the specific height of the gas cylinder to ensure that the clamping mechanism is perfectly matched with the gas cylinder, which increases the ease of operation of the device;

[0018] 3. The linkage mechanism of the present invention converts the rotational motion of the rotating rod into the rotational motion of the lead screw through the meshing transmission of the first bevel gear and the second bevel gear, thereby realizing the transmission conversion of spatial angle. Through the meshing transmission of the worm and the worm wheel, the motion is further transmitted and converted. The worm drive has a self-locking performance, which increases the safety of the device, prevents the clamping mechanism from loosening due to external force, and ensures the stability of the gas cylinder during the transfer process.

[0019] 4. In the clamping mechanism of the present invention, the worm gear converts the rotational motion of the rotating rod into the rotation of the first support rod through the worm. Then, under the action of the first gear and the second gear, the second support rod rotates relative to each other. The two sets of second clamping plates clamp or release the gas cylinder. It is suitable for gas cylinders of different diameters within a certain range, which enhances the versatility and flexibility of the device. The second rubber pad can significantly increase the friction between the second clamping plate and the surface of the gas cylinder, prevent the gas cylinder from sliding during the clamping process, and improve the safety and reliability of the device.

A first clamping plate 208 is fixedly connected to one end of the first bracket 207. A first rubber pad 209 is fixedly connected to the inner side of the first clamping plate 208.

[0036] A damper 210 is fixedly connected to the middle of the lower surface of the support plate 202, and a spring 211 is sleeved on the bottom of the outer surface of the guide rod 201.

[0037] The adjustment mechanism 3 includes a column 301 fixed on one side of the upper surface of the base 1. A sleeve 302 is slidably connected to the outer surface of the column 301. A lead screw 303 is rotatably connected inside the sleeve 302. The lead screw 303 passes through the column 301 and is rotatably connected to it.

[0038] The linkage mechanism 4 includes a fixed box 401 fixed to one end of the column 301. A rotating rod 402 is rotatably connected to the inner side of the fixed box 401 near the lead screw 303. A rocker arm 403 is fixedly connected to one end of the rotating rod 402.

[0039] A first bevel gear 404 is fixedly connected to one side of the outer surface of the rotating rod 402. A second bevel gear 405 is meshed with the outer surface of the first bevel gear 404. The second bevel gear 405 is fixedly connected to the lead screw 303.

[0040] A worm gear 406 is fixedly connected to the other side of the outer surface of the rotating rod 402, and a worm wheel 407 is meshed with the outer surface of the worm gear 406.

[0041] The worm gear 407 is internally fixedly connected to a first support rod 408, the top of the outer surface of the first support rod 408 is fixedly connected to a first gear 409, the outer surface of the first gear 409 is meshed with a second gear 410, and the second gear 410 is internally fixedly connected to a second support rod 411.

[0042] The clamping mechanism 5 includes a second bracket 501 fixed in the middle of the outer surface of the first support rod 408 and the second support rod 411. A second clamping plate 502 is fixedly connected to one end of the second bracket 501, and a second rubber pad 503 is fixedly connected to the inner side of the second clamping plate 502.

[0043] Self-locking casters 6 are fixedly connected to both sides of the lower surface of the base 1, and a support column 7 is fixedly connected to the side of the lower surface of the base 1 away from the self-locking casters 6.

[0044] A push rod 8 is fixedly connected to the edge of the upper surface of the base 1, and a reinforcing rod 9 is fixedly connected to the top of the outer surface of the push rod 8.

[0045] It should be noted that the base 1, as the basic structure of the entire device, bears all other components and provides a stable support platform. The clamping mechanism 2 is used to directly contact and fix the special gas cylinder, and is a key component to ensure that the gas cylinder does not move during the transfer process. The adjustment mechanism 3 allows the user to adjust according to the height of the gas cylinder, so that the clamping mechanism 5 can adapt to gas cylinders of different sizes. This adjustability improves the versatility and flexibility of the device and reduces the usage limitations caused by differences in gas cylinder size. The linkage mechanism 4 transmits the action of the adjustment mechanism 3 to the clamping mechanism 5 to ensure the continuity and consistency of the clamping action. The clamping mechanism 5 achieves the final clamping of the gas cylinder to ensure that the gas cylinder always remains firmly clamped during the transfer process.

[0046] The guide rod 201 provides vertical guidance for the pallet 202, ensuring its stability during lifting and lowering and preventing instability due to tilting or swaying. The pallet 202 carries the special gas cylinder. Under the weight of the gas cylinder, the pallet 202 moves downward. Through the hinge of the fixed block 203 and the connecting rod 204, the slider 205 slides on the surface of the guide rail 206, adjusting horizontally according to the diameter of the gas cylinder, making the clamping action more flexible and adaptable to gas cylinders of different diameters. The slider 205 and the guide rail 206 simultaneously provide horizontal guidance for the first bracket 207, ensuring that the first clamping plate 208 maintains linear motion during horizontal movement and preventing uneven clamping due to tilting. The first clamping plate 208 contacts the gas cylinder through the first rubber pad 209 and applies clamping force. The first rubber pad 209 increases the clamping force during operation. The friction of the clamping mechanism prevents the gas cylinder from sliding and acts as a buffer to avoid damage to the surface of the gas cylinder, thus protecting its integrity. The clamping mechanism 2 uses a gravity self-locking mechanism to automatically lock the clamping state after clamping the gas cylinder, preventing loosening due to accidental vibration or external force. This greatly improves the reliability of the clamping and ensures that the gas cylinder remains firmly clamped during the transfer process, avoiding accidents such as tipping or slipping due to unstable clamping. At the same time, no additional operation steps are required. Once the gas cylinder is placed in place, the clamping mechanism 2 will automatically complete the clamping and locking actions, greatly simplifying the operation process, reducing the workload of operators, and improving work efficiency. When it is necessary to release the gas cylinder, simply lift the gas cylinder upwards, and the clamping mechanism 2 will quickly release the gas cylinder, making the entire transfer process more efficient and further enhancing the practicality of the device.

[0047] Preferably, the damper 210 provides damping force during the lifting and lowering of the pallet 202, playing a role in buffering and shock absorption. It can effectively reduce the shaking of the gas cylinder caused by rapid lifting or external impact, and improve the stability and safety of the clamping process. The spring 211 provides elastic support and assists the pallet 202 in resetting during the lifting and lowering process, eliminating the need for manual resetting.

[0048] Preferably, the column 301 serves as a support component for the adjustment mechanism 3 and is fixed on the base 1, providing a stable mounting foundation for the sleeve 302 and the lead screw 303. The sleeve 302 slides on the column 301 and achieves lifting and lowering actions through cooperation with the lead screw 303. Users can make fine adjustments according to the specific height of the gas cylinder to ensure that the clamping mechanism 5 is perfectly matched with the gas cylinder, thereby increasing the ease of operation of the device.

[0049] Preferably, the fixed box 401 provides an installation and support platform for each component of the linkage mechanism 4, ensuring the relative position stability between the components and improving the overall accuracy and reliability of the linkage mechanism 4. The rotating rod 402 is connected to the lead screw 303 through transmission, so that the linkage mechanism 4 links the adjusting mechanism 3 and the clamping mechanism 5, making the operation more convenient. By shaking the rocker arm 403, the rotating rod 402 can be easily driven to rotate, thereby realizing the action of the entire linkage mechanism 4, improving the convenience and efficiency of operation, and enabling users to quickly complete the adjustment of the adjusting mechanism 3 and the clamping mechanism 5.

[0050] Preferably, the rotational motion of the rotating rod 402 is converted into the rotational motion of the lead screw 303 through the meshing transmission of the first bevel gear 404 and the second bevel gear 405, realizing the transmission conversion of spatial angle, making the transmission more compact and efficient, and improving the overall performance of the device.

[0051] Preferably, the motion is further transmitted and converted through the meshing transmission of the worm 406 and the worm wheel 407. The worm 406 transmission has a self-locking function, which means that under normal circumstances, the worm wheel 407 cannot drive the worm 406 in the reverse direction, thereby increasing the safety of the device, preventing the clamping mechanism 5 from loosening due to external forces, and ensuring the stability of the gas cylinder during the transfer process.

[0052] Preferably, the worm gear 407 converts the rotational motion of the rotating rod 402 into the rotation of the first support rod 408 through the worm 406. Then, under the action of the first gear 409 and the second gear 410, the second support rod 411 rotates relative to each other. The two sets of second clamping plates 502 clamp or release the gas cylinder, which can achieve precise clamping control and provide stable fixing force.

[0053] Preferably, under the action of the first gear 409 and the second gear 410, the first support rod 408 and the second support rod 411 rotate, thereby causing the two sets of second brackets 501 to rotate relative to each other, so that the two sets of second clamping plates 502 clamp the special gas cylinder. This is applicable to gas cylinders of different diameters within a certain range, enhancing the versatility and flexibility of the device. The material of the second rubber pad 503 has a high coefficient of friction, which can significantly increase the friction between the second clamping plate 502 and the surface of the gas cylinder, preventing the gas cylinder from slipping during the clamping process and improving the safety and reliability of the device.

[0054] Preferably, the self-locking casters 6 allow the entire device to be easily moved to different locations, improving its flexibility and applicability. The self-locking function prevents the device from sliding by locking the casters after it reaches the designated position, ensuring the device remains stable during use and preventing the gas cylinder from tipping over or being damaged due to accidental movement. The support column 7 provides support when the device stops moving, increasing its stability and preventing the self-locking casters 6 from being damaged under prolonged stress, thus improving the device's reliability and durability.

[0055] Preferably, the push rod 8 provides a convenient operating handle for the user, making it easy for the user to push the device to move. The push rod 8 has a square structure, which can increase the friction of the operator's hand and prevent the hand from slipping during the pushing process, thereby improving the safety and reliability of the operation. The reinforcing rod 9 is used to enhance the structural strength of the push rod 8 and prevent the push rod 8 from being deformed or damaged by external forces during use.

[0056] In summary, the device is pushed to the designated position, and the flexibility and self-locking function of the self-locking casters 6 ensure stability during use. The support column 7 provides additional support when the device stops moving. The special gas cylinder is placed on the pallet 202. Under the weight of the gas cylinder, the pallet 202 moves downward along the guide rod 201. At this time, the hinge structure of the fixing block 203 and the connecting rod 204 drives the slider 205 to slide on the surface of the guide rail 206, automatically adjusting its horizontal position according to the diameter of the gas cylinder. As the pallet 202 descends, the first bracket 207 drives the first clamping plate 208 to move closer to the gas cylinder. The first rubber pad 209 contacts the surface of the gas cylinder and applies clamping force. Using a gravity self-locking mechanism, the clamping state is automatically locked after the gas cylinder is placed in place, requiring no additional operation. This effectively prevents the clamping from loosening due to accidental vibration or external force, ensuring that the gas cylinder remains firmly clamped during transportation. According to the height of the gas cylinder, the rocker arm 403 is rotated to rotate the rod 4. 02. Rotation: Under the action of the first bevel gear 404 and the second bevel gear 405, the lead screw 303 rotates, adjusting the position of the sleeve 302 on the column 301, thereby driving the clamping mechanism 5 to move up and down, ensuring that the clamping mechanism 5 matches the height of the gas cylinder. At the same time, through the meshing transmission of the worm gear 406 and the worm wheel 407, the first gear 409 and the second gear 410 drive the first support rod 408 and the second support rod 411 to rotate. The two sets of second brackets 501 rotate relative to each other, so that the second clamping plate 502 clamps the gas cylinder. After the device is ready, the operator pushes the device to move through the push rod 8. After reaching the destination, the clamping mechanism 5 releases the gas cylinder. By lifting the gas cylinder upward, the self-locking mechanism of the clamping mechanism 2 is released, and the gas cylinder is quickly released, completing the transfer process.
