Description

Technical Field

[0001] This utility model relates to the field of gas filling technology, and in particular to a cylinder rubber ring loading and unloading machine. Background Technology

[0002] A gas cylinder is a container used to store and transport gases. It is typically made of high-strength steel to withstand the high pressure of the gas inside. Gas cylinders are widely used in industry, medicine, laboratories, and households. Common gases include oxygen, nitrogen, argon, carbon dioxide, and propane. Because gas cylinders are primarily used to hold gases, they need to have a certain degree of airtightness; currently, the common method is to install rubber rings on the cylinders.

[0003] When installing rubber rings on gas cylinders, a rubber ring loading and unloading machine is generally required. This machine typically consists of a main body and a restraining section. Current rubber ring loading and unloading machines have certain drawbacks. For example, the restraining section is usually a ring, which is not convenient for clamping gas cylinders of different sizes; and when placing the cylinder, workers may cause the cylinder's center to misalign with the mounting section on the machine's main body.

[0004] A utility model application with application number CN202021345381.4 and publication number CN212705321 U discloses a cylinder rubber ring loading and unloading machine, including a fixed rod, a loading and unloading machine body, and a base. A central plate is fixedly installed on the top of the base at one end of the loading and unloading machine body. Sleeves are fixedly installed on both sides of the central plate. A fixed rod is fixedly installed inside the sleeves. A threaded rod is movably installed inside the fixed rod. A limit block is fixedly installed on the inner side of the threaded rod. It solves the problem of clamping cylinders of different sizes through the cooperation of the threaded rod and the limit block. However, because the threaded rod needs to be adjusted separately, it still cannot effectively solve the problem that the center of the cylinder is easily misaligned with the mounting part on the rubber ring loading and unloading machine body when the operator places the cylinder.

Detailed Implementation

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example:

[0030] like Figures 1 to 2As shown, in order to solve the above problems, this embodiment discloses a gas cylinder rubber ring loading and unloading machine, including a rubber ring loading and unloading machine body 10, a clamping component 20 and a lifting and mounting component 30. The rubber ring loading and unloading machine body 10 is disposed on the top of the lifting and mounting component 30 and is used for the installation or removal of the gas cylinder rubber ring. The clamping component 20 is disposed on the lifting and mounting component 30 and is configured to cooperate with the rubber ring loading and unloading machine body 10. The lifting and mounting component 30 is used to realize the lifting and lowering of the clamping component 20.

[0031] The clamping assembly 20 includes a base plate 200, a positioning plate 201, and a clamping structure 202. The positioning plate 201 is mounted on the base plate 200, which is mounted on the lifting and mounting assembly 30. The clamping structure 202 is mounted on the positioning plate 201 and is used to clamp the gas cylinder. The positioning plate 201 has several circles of different diameters in the middle, and the centers of the circles correspond to the center of the mounting part on the main body 10 of the rubber ring loading and unloading machine.

[0032] The clamping structure 202 includes a movable member 203 and a pair of clamping parts 204. The movable member 203 is disposed on the positioning plate 201 and is configured to cooperate with several circles. The pair of clamping parts 204 are disposed on the movable member 203 and are configured to cooperate with several circles. The pair of clamping parts 204 can clamp the steel cylinder under the drive of the movable member 203.

[0033] In use, this invention allows the gas cylinder to be placed on the positioning plate 201. The cylinder's diameter is then matched with circles of different diameters on the positioning plate 201, ensuring that the center of the cylinder aligns with the center of the mounting portion on the main body 10 of the gas cylinder loading and unloading machine. This solves the problem of misalignment between the cylinder's center and the mounting portion on the machine body 10, which is easily caused by workers placing the cylinder. Furthermore, by configuring the clamping structure 202 as a moving part 203 and a pair of clamping parts 204, the moving part 203 drives the pair of clamping parts 204 to clamp the cylinder, thus solving the problem that current gas cylinder loading and unloading machines are inconvenient for clamping cylinders of different sizes.

[0034] The main body 10 of the rubber ring loading and unloading machine can be the same as that used in existing rubber ring loading and unloading machines. It should at least include a loading and unloading machine body, a drive unit, and a mounting unit. The drive unit is located within the loading and unloading machine body, and the mounting unit is located at the bottom of the loading and unloading machine body, with one end passing through the loading and unloading machine body and fixedly connected to the output end of the drive unit. The mounting unit is rotatably engaged with the loading and unloading machine body. Through the cooperation of the drive unit and the mounting unit, the installation or removal of the rubber ring can be completed.

[0035] like Figure 2As shown, in order to further ensure that the center of the gas cylinder corresponds to the center of the mounting part on the main body 10 of the rubber ring loading and unloading machine, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the moving part 203 includes a moving part 205 and a sliding part 206. The moving part 205 and the sliding part 206 are disposed on the positioning plate 201 and are respectively located on both sides of a plurality of circles. A pair of clamping parts 204 are disposed on the moving part 205 and the sliding part 206 and are respectively located at both ends of the moving part 205 and the sliding part 206. The moving part 205 is used to install and drive the pair of clamping parts 204, and the sliding part 206 is used to install and cooperate with the moving part 205 to drive the pair of clamping parts 204.

[0036] like Figure 3 As shown, the moving part 205 includes a moving track 207, a bidirectional reverse thread rotating rod 208, a driving member 209, and a pair of threaded sliders 210. The moving track 207 is fixedly mounted on the positioning plate 201 and located on one side of several circles. The bidirectional reverse thread rotating rod 208 is disposed within the moving track 207, with both ends of the bidirectional reverse thread rotating rod 208 passing through the moving track 207 and rotatably connected to it. The driving member 209 is disposed on one side of the moving track 207 and fixedly connected to the end of the bidirectional reverse thread rotating rod 208, and is used to drive the bidirectional reverse thread rotating rod. 208, the bidirectional reverse threaded rotating rod 208 is provided with a positive thread from the middle of the bidirectional reverse threaded rotating rod 208 to one end of the bidirectional reverse threaded rotating rod 208 and a reverse thread from the middle of the bidirectional reverse threaded rotating rod 208 to the other end of the bidirectional reverse threaded rotating rod 208. A pair of threaded sliders 210 are respectively provided at both ends of the bidirectional reverse threaded rotating rod 208. One threaded slider 210 is threadedly connected to the end of the bidirectional reverse threaded rotating rod 208 with the positive thread, and the other threaded slider 210 is threadedly connected to the end of the bidirectional reverse threaded rotating rod 208 with the reverse thread.

[0037] The drive component 209 includes a drive handle 211 and a connector 212. The drive handle is fixed on the connector 212, and one end of the connector 212 is fixedly connected to one end of the bidirectional reverse thread rotating rod 208.

[0038] The sliding part 206 includes a sliding track 213, a sliding rod 214 and a pair of sliding blocks 215. The sliding track 213 is fixedly mounted on the positioning plate 201 and is located on the other side of several circles to cooperate with the moving track 207. The sliding rod 214 is disposed inside the sliding track 213 and is fixedly connected to the sliding track 213. The pair of sliding blocks 215 are disposed inside the sliding track 213 and are respectively sleeved on both ends of the sliding rod 214. The sliding blocks 215 are slidably connected to the sliding rod 214.

[0039] The clamping part 204 includes a connecting plate 216, a mounting arm 217, and an arc-shaped clamping plate 218. The connecting plate 216 is disposed at one end of the moving track 207 and the sliding track 213, and the two ends of the connecting plate 216 are respectively disposed on the sliding block 215 and the threaded slider 210 located on the same side. The connecting plate 216 is fixedly connected to the sliding block 215 and the threaded slider 210. The mounting arm 217 is disposed on the connecting plate 216, and the arc-shaped clamping plate 218 is disposed on the mounting arm 217. The arc-shaped clamping plate 218 is configured to cooperate with several circles.

[0040] The curved clamping plate 218 has a flexible rubber pad at one end for clamping the gas cylinder. The flexible rubber pad can fit more closely to the outside of the gas cylinder, thus clamping the gas cylinder better, and at the same time preventing the curved clamping plate 218 from causing scratches or other damage to the outside of the gas cylinder.

[0041] In use, by rotating the drive handle 211, the bidirectional reverse thread rotating rod 208 is driven to rotate, thereby causing a pair of threaded sliders 210 to move closer or further away simultaneously. Since the threaded sliders 210 and the sliding block 215 are connected by the connecting plate 216, the sliding block 215 will also slide accordingly when the threaded sliders 210 move. This allows the pair of clamping parts 204 to move closer or further away simultaneously by rotating the drive handle 211, thereby clamping and releasing the gas cylinder. Since the pair of clamping parts 204 move closer or further away simultaneously, the gas cylinder will not move when the pair of clamping parts 204 clamp it, thus further ensuring that the center of the gas cylinder corresponds to the center of the mounting part on the main body 10 of the rubber ring loading and unloading machine.

[0042] In another embodiment, to facilitate clamping or releasing the gas cylinder, the drive component 209 includes a motor, the output shaft of which is fixedly connected to one end of the bidirectional reverse thread rotating rod 208. In use, the motor can drive the bidirectional reverse thread rotating rod 208 to rotate, allowing the pair of clamping parts 204 to simultaneously move closer or further apart, thereby clamping and releasing the gas cylinder.

[0043] like Figure 2 As shown, in order to accommodate cylinders of different heights, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the lifting installation assembly 30 includes a bottom mounting plate 300, a mounting frame 301, a fixing structure 302 and a lifting structure 303. The mounting frame 301 is fixedly mounted on the bottom mounting plate 300, the lifting structure 303 is mounted on the mounting frame 301, the fixing structure 302 is mounted on the lifting structure 303, and the clamping assembly 20 is mounted on the fixing structure 302.

[0044] like Figure 4As shown, the mounting frame 301 includes a bottom support arm 304, a top connecting arm 305, and a pair of vertical mounting arms 306. The pair of vertical mounting arms 306 are disposed between the bottom support arm 304 and the top connecting arm 305. The two ends of the pair of vertical mounting arms 306 are fixedly connected to the two ends of the bottom support arm 304 and the top connecting arm 305, respectively. The lifting structure 303 is disposed between the pair of vertical mounting arms 306.

[0045] The lifting structure 303 includes a sliding mounting base 307, a fixed connecting rod 308, and a pair of drive cylinders 309. The fixed structure 302 includes a pair of L-shaped connecting arms 310. The pair of drive cylinders 309 are disposed between a pair of vertical mounting arms 306, and one end of the pair of drive cylinders 309 is fixedly connected to the top connecting arm 305. The sliding mounting base 307 is disposed between the pair of vertical mounting arms 306 and is located below the pair of drive cylinders 309. Both sides of the sliding mounting base 307 are slidably connected to the pair of vertical mounting arms 306. The fixed connecting rod 308 is disposed on the sliding mounting base 307. The output end of the pair of drive cylinders 309 is fixedly connected to the fixed connecting rod 308. The pair of L-shaped connecting arms 310 are disposed on the sliding mounting base 307 and are fixedly connected to the sliding mounting base 307. The base plate 200 is disposed on the pair of L-shaped connecting arms 310 and is fixedly connected to the L-shaped connecting arms 310.

[0046] like Figure 5 As shown, the sliding mounting base 307 has several sliding wheels 311 at both ends, and the sliding wheels 311 are rotatably connected to the sliding mounting base 307. A pair of vertical mounting arms 306 are provided with sliding grooves 312 that cooperate with the sliding wheels 311. The sliding wheels 311 are located in the sliding grooves 312 and can move along the sliding grooves 312.

[0047] In use, a pair of drive cylinders 309 can be used to drive the sliding mounting base 307 to move along the sliding groove 312 on a pair of vertical mounting arms 306, thereby driving the clamping assembly 20 to lift and lower, thus realizing the lifting and lowering of the cylinder on the positioning plate 201, which can easily adapt to cylinders of different heights.

[0048] Working principle of this utility model:

[0049] In use, the gas cylinder can be placed on the positioning plate 201, and then the cylinder diameter can be matched with circles of different diameters on the positioning plate 201 to ensure that the center of the gas cylinder corresponds to the center of the mounting part on the main body 10 of the rubber ring loading and unloading machine. Then, the moving part 203 drives a pair of clamping parts 204 to clamp the gas cylinder. When the distance between the gas cylinder and the mounting part on the main body 10 of the rubber ring loading and unloading machine is far, the height of the gas cylinder can be adjusted by the lifting mounting component 30 so that the gas cylinder and the mounting part on the main body 10 of the rubber ring loading and unloading machine can be matched.

[0050] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
