Description

Technical Field

[0001] The utility model relates to a manual vehicle, such as a wheelbarrow or a cradle, and the technical field of sleds, in particular to a transfer device for a gas storage tank. Background Art

[0002] A gas storage tank is a gas storage tank. A gas storage tank refers to a device specifically used to store gas, including a low-pressure gas storage tank and a normal-pressure gas storage tank. Gas storage tanks will be transported after they are produced. During the transportation process, when the gas storage tank needs to be moved a short distance, a transfer device will be used to move it.

[0003] The transfer device is mostly a small cart with a frame. When transporting through the transfer device, the gas tank is usually placed in the frame and then the cart is pushed. Due to the different transfer locations, the road conditions will also be different. The road conditions in some places may be relatively poor, which will cause the gas tank in the frame to shake, and then cause the gas tank to collide with the cart. The collision can easily cause damage to the gas tank pressure reducing valve, especially when there is a certain gas pressure in the gas tank, which can cause the gas tank to explode and other dangers. Therefore, there is an urgent need for a gas storage tank transfer device that can fix the gas tank. Utility Model Content

[0031] Furthermore, the clamping mechanism includes a connecting plate 7, which is slidably connected to the inside of the placement frame 5, a sliding groove 8 is provided on the upper side of the connecting plate 7, a sliding block 9 is slidably connected to the inside of the sliding groove 8, a clamping plate 10 is fixedly connected to the upper side of the sliding block 9, the clamping plate 10 is arranged on the upper side of the connecting plate 7, a rubber layer 11 is fixedly connected to the side of the clamping plate 10 facing the center, a threaded rod 12 is rotatably connected to the inside of the sliding groove 8, the threaded rod 12 passes through the sliding block 9, and a sliding groove 8 is also provided on the upper side of the connecting plate 7. The internal connection structures of the two sliding grooves 8 are the same and are symmetrically arranged, so that the threaded rotation directions of the two threaded rods 12 are opposite, and a spring 17 is fixedly connected to the lower side of the connecting plate 7, and the lower end of the spring 17 is fixedly connected to the bottom wall of the placement frame 5;

[0032] Further, the connection plate 7 is internally rotatably connected with a connection shaft 13, which is arranged between the two sliding grooves 8, and the opposite surfaces of the two threaded rods 12 are fixedly connected to the two ends of the connection shaft 13 respectively. The inner surface of the placement frame 5 is provided with an engagement groove 14, which is arranged at the rear side, and the right side of the engagement groove 14 is provided with a tooth surface. The rear end of the rear threaded rod 12 is fixedly connected with a transmission rod 15, and the rear end of the transmission rod 15 rotates and extends out of the outer surface of the connection plate 7, and the rear end of the transmission rod 15 extends into the inside of the engagement groove 14. The rear end of the transmission rod 15 is fixedly connected with a gear 16, and the gear 16 meshes with the tooth surface of the engagement groove 14. The inner surface of the placement frame 5 is provided with a limiting groove 18, and the limiting groove 18 is arranged at a front position. The outer surface of the connection plate 7 is fixedly connected with a limiting block 19, and the front side of the limiting block 19 extends into the inside of the limiting groove 18.

[0033] Furthermore, when transporting the gas tank, after the gas tank is placed inside the frame 5, the limiting ring 6 on the upper side of the frame 5 will limit the gas tank to a certain extent. At the same time, due to the weight of the gas tank placement frame 5 itself, the gas tank placement frame 5 presses the connecting plate 7 to move downward. At this time, the spring 17 begins to become compressed, and the connecting plate 7 will drive the gear 16 to move downward. Because the gear 16 will mesh with the tooth surface of the meshing groove 14, the gear 16 will rotate during the downward movement. The gear 16 drives the transmission rod 15 to rotate, and the transmission rod 15 drives the rear threaded rod 12 to rotate. The rear threaded rod 12 drives the threaded rear sliding block 9 to move forward. The rear sliding block 9 drives the clamping plate 10 to move, and the rear threaded rod 12 drives the connecting shaft 13 to rotate. The connecting shaft 13 drives the front threaded rod 12 to rotate, and the front threaded rod 12 drives the threaded front sliding block 9 to move. Because the threads of the two threaded rods 12 are rotated in opposite directions, the front sliding block 9 and the front clamping plate 10 will move toward the rear side, and then the two clamping plates 10 will clamp and fix the gas tank, and then the gas tank will not shake during transportation. The rubber layer 11 makes the clamping more tight, and the soft rubber also avoids damage to the gas tank during clamping. The limit block 19 and the limit groove 18 cooperate to limit the connecting plate 7. When taking out the gas tank, it only needs to move upward to take it out. At the same time, it can be known from the above that the spring 17 will reset from the compressed state, and then the two clamping plates 10 will move away from each other and release the clamping. In this way, when the gas tank is placed in the placement frame 5, the gas tank can be automatically clamped and fixed, so that the gas tank will not shake during the transportation process, thereby avoiding collision of the gas tank and ensuring that it will not be damaged during transportation.

[0034] Working principle: When transporting the gas tank, after the gas tank is placed inside the frame 5, the limiting ring 6 on the upper side of the frame 5 will limit the gas tank to a certain extent. At the same time, due to the weight of the gas tank placement frame 5 itself, the gas tank placement frame 5 presses the connecting plate 7 to move downward. At this time, the spring 17 begins to become compressed, and the connecting plate 7 will drive the gear 16 to move downward. Because the gear 16 will mesh with the tooth surface of the meshing groove 14, the gear 16 will rotate during the downward movement. The gear 16 drives the transmission rod 15 to rotate, and the transmission rod 15 drives the rear threaded rod 12 to rotate. The rear threaded rod 12 drives the threaded rear sliding block 9 to move forward, and the rear sliding block 9 drives the clamping plate 10 to move, and the rear threaded rod 12 drives the connecting shaft 13 Rotate, the connecting shaft 13 drives the front threaded rod 12 to rotate, and the front threaded rod 12 drives the threaded front sliding block 9 to move. Because the threads of the two threaded rods 12 are in opposite directions, the front sliding block 9 and the front clamping plate 10 will move backward, and then the two clamping plates 10 will clamp and fix the gas tank, and then the gas tank will not shake during transportation. The rubber layer 11 makes the clamping more firm, and the soft rubber also avoids damage to the gas tank during clamping. The limit block 19 and the limit groove 18 cooperate to limit the connecting plate 7. When taking out the gas tank, you only need to move it upward to take it out. At the same time, it can be seen from the above that the spring 17 will reset from the compressed state, and then the two clamping plates 10 will move away from each other and release the clamping.
