Description

Technical Field

[0001] The utility model belongs to the technical field of liquid ammonia crane pipes, and in particular relates to a gas phase quick connector for liquid ammonia crane pipes. Background Art

[0002] The main function of the liquid nitrogen crane is to load and unload liquefied natural gas. The liquid nitrogen crane mainly consists of a column, an inner arm, an outer arm, an outrigger, a swivel joint, and a spring cylinder. The swivel joint is mainly used to connect the inner arm, outer arm, and outrigger together, so that the liquid nitrogen crane can rotate relative to each other and bear the load, and ensure that the liquid ammonia does not leak during the transportation process.

[0003] When liquid nitrogen is transported through the crane pipe, there is likely to be a height difference between the output end of the outer arm and the inlet of the liquid nitrogen receiving device. At this time, the inner arm and the outer arm can adjust the position of the outer arm according to the inlet of the receiving device with the assistance of the rotary joint. In order to enable the crane pipe to transport liquid nitrogen to receiving devices at different heights, the lengths of the inner arm and the outer arm need to be set long enough. This setting easily leads to a relatively large space occupation when the crane pipe is stored together as a whole, and it is also inconvenient to transport the crane pipes stored together.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In response to the problems in the related art, the utility model proposes a gas phase quick connector for liquid ammonia crane pipe to overcome the above technical problems existing in the existing related technology.

[0011] Furthermore, the driving assembly further includes an anti-slip groove, and a plurality of the anti-slip grooves are arranged in a circumferential array on the outer surface of the rotating tube.

[0012] Furthermore, the locking assembly includes a mounting plate, which is fixedly connected to the outer surface of the connecting tube, and a connecting rod is movably connected to one side of the mounting plate. One end of the connecting tube passes through the mounting plate and is fixedly connected to a locking tooth block, and the locking tooth block is engaged with the driving tooth groove.

[0030] See also Figures 1-6 As shown, the utility model is a gas phase quick connector for a liquid ammonia crane pipe, comprising a connecting pipe 1, an adjusting pipe 2 is provided inside the connecting pipe 1, an adjusting component 3 is provided on the outer surface of the connecting pipe 1 and the adjusting pipe 2, a driving component 4 is provided on the outer surface of the connecting pipe 1, the driving component 4 is dynamically connected to the adjusting end of the adjusting component 3, a locking component 5 is provided on the outer surface of the connecting pipe 1, the locking end of the locking component 5 is dynamically connected to the driving end of the driving component 4, and a sealing component 6 is provided between the connecting pipe 1 and the adjusting pipe 2.

[0031] The driving assembly 4 is used to drive the adjusting assembly 3 to change the length between the connecting pipe 1 and the adjusting pipe 2, the locking assembly 5 is used to lock the driving assembly 4, and the sealing assembly 6 is used to seal the connection position between the connecting pipe 1 and the adjusting pipe 2.

[0032] By connecting the rotary joint connecting tube 1 and one end of the adjusting tube 2 with the corresponding inner arm and outer arm, when adjusting the height between the inner arm and the outer arm, the adjusting assembly 3 is driven by the driving assembly 4, so that the adjusting tube 2 moves inside the moving tube 2 under the drive of the adjusting assembly 3, so that the length between the adjusting tube 2 and the connecting tube 1 can be adjusted. After the adjustment is completed, the position of the driving assembly 4 is locked by the locking assembly 5.

[0033] The adjusting component 3 can be driven by the driving component 4, so that the adjusting tube 2 moves inside the connecting tube 1 under the drive of the adjusting component 3, and the height between the adjusting tube 2 and the connecting tube 1 can be adjusted. The above arrangement allows the height between the inner arm and the outer arm connected together by the connecting tube 1 and the adjusting tube 2 to be adjusted. At the same time, the overall length of the inner arm and the outer arm does not need to be set too long, and the adjusting tube 2 can be moved to the inside of the connecting tube 1 when the inner arm and the outer arm are folded together. The above arrangement prevents the components on the crane pipe from occupying too much space after being folded together, thereby making it more convenient to transport the crane pipe.

[0034] In one embodiment, for the above-mentioned adjustment component 3, the adjustment component 3 includes a connecting seat 301, the connecting seat 301 is fixedly connected to the outer surface of the connecting pipe 1, the internal rotation of the connecting seat 301 is connected to a threaded barrel 302, the internal thread of the threaded barrel 302 is connected to an adjusting screw 303, the outer surface of the adjusting pipe 2 is fixedly connected to a connecting block 304, and the adjusting screw 303 is fixedly connected to the connecting block 304.

[0035] By driving the threaded barrel 302 to rotate inside the connecting seat 301, the adjusting screw 303 threadedly connected to the threaded barrel 302 can move inside the threaded barrel 302, and the moving adjusting screw 303 drives the adjusting tube 2 to move inside the connecting tube 1 through the connecting block 304. The arrangement of the threaded barrel 302 and the adjusting screw 303 ensures that the length between the connecting tube 1 and the adjusting tube 2 will not change arbitrarily after being adjusted appropriately.

[0036] In one embodiment, for the above-mentioned driving assembly 4, the driving assembly 4 includes a rotating tube 401, the rotating tube 401 is rotatably connected to the connecting tube 1, the inner wall of the rotating tube 401 is provided with a receiving groove 402, the inner wall of the receiving groove 402 is provided with a driving tooth groove 403, and the outer surface of the threaded cylinder 302 is fixedly connected with a driving gear 404, and the driving gear 404 and the driving tooth groove 403 are engaged with each other.

[0037] By rotating the rotating tube 401, the rotating tube 401 drives the driving gear 404 to rotate through the driving tooth groove 403, and the rotating driving gear 404 drives the threaded cylinder 302 to rotate inside the connecting seat 301, and changes the length between the connecting tube 1 and the adjusting tube 2. Since the rotating tube 401 is arranged on the outer surface of the connecting tube 1, it is relatively convenient to rotate the rotating tube 401, and it is also relatively convenient to adjust the position of the adjusting tube 2.

[0038] In one embodiment, for the above-mentioned driving assembly 4 , the driving assembly 4 further includes an anti-slip groove 405 , and a plurality of the anti-slip grooves 405 are arranged in a circumferential array on the outer surface of the rotating tube 401 .

[0039] The anti-slip groove 405 allows the operator to hold and rotate the rotating tube 401 with greater friction at the contact point between the operator's hand and the rotating tube 401, thereby avoiding the occurrence of hand slippage when rotating the rotating tube 401.

[0040] In one embodiment, for the above-mentioned locking assembly 5, the locking assembly 5 includes a mounting plate 501, the mounting plate 501 is fixedly connected to the outer surface of the connecting pipe 1, and a connecting rod 502 is movably connected to one side of the mounting plate 501. One end of the connecting rod 502 passes through the mounting plate 501 and is fixedly connected to a locking tooth block 503. The locking tooth block 503 is meshed with the driving tooth groove 403. A spring 504 is fixedly connected between the locking tooth block 503 and the mounting plate 501, and the other end of the connecting rod 502 is fixedly connected to a pull plate 505.

[0041] The spring 504 can push the locking tooth block 503, so that the locking tooth block 503 drives the connecting rod 502 to slide on the mounting plate 501, and at the same time the locking tooth block 503 directly moves to the inside of the receiving groove 402 and directly engages with the driving tooth groove 403. Since the two connecting rods 502 can limit the locking tooth block 503 through the mounting plate 501, the rotating tube 401 will not rotate arbitrarily on the outer surface of the connecting tube 1 after the locking tooth block 503 is engaged with the driving tooth groove 403, thereby making The stability of the connecting tube 1 and the adjusting tube 2 can be guaranteed after the length adjustment is completed; when the rotating tube 401 is rotated, the two connecting rods 502 are pulled by the pull plate 505, so that the locking tooth block 503 can squeeze the spring 504 backward and move directly out from the inside of the storage groove 402, so that the locking tooth block 503 no longer limits and locks the rotating tube 401. This arrangement makes it easier to operate when the rotating tube 401 is rotated to adjust the length between the adjusting tube 2 and the connecting tube 1.

[0042] In one embodiment, for the above-mentioned sealing assembly 6, the sealing assembly 6 includes a sealing groove 601, the sealing groove 601 is opened on the outer surface of the regulating tube 2, and a plurality of sealing grooves 601 are arranged in an array. A sealing ring 602 is arranged inside the sealing groove 601, and the sealing ring 602 is in contact with the inner wall of the connecting tube 1.

[0043] When the regulating tube 2 moves inside the connecting tube 1, the regulating tube 2 drives the sealing ring 602 to slide on the inner wall of the connecting tube 1 through the sealing groove 601. The arrangement of multiple sealing rings 602 ensures the sealing of the connection position between the port of the regulating tube 2 and the inner wall of the connecting tube 1, thereby preventing leakage during the transportation of liquid nitrogen.

[0044] In one embodiment, for the connecting pipe 1 , one end of the connecting pipe 1 opposite to the regulating pipe 2 is fixedly connected with a connecting flange 7 .

[0045] The connecting flanges 7 on the connecting pipe 1 and the adjusting pipe 2 are both equipped with rotating joints, and the corresponding ends of the two rotating joints are connected to the inner arm and the outer arm respectively. The above arrangement allows the inner arm and the outer arm to rotate under the action of the rotating joints. At the same time, if the height of the inner arm and the outer arm is not enough after adjustment, the length between the connecting pipe 1 and the adjusting pipe 2 can be adjusted.

[0046] Through the above technical solution, 1. The driving component 4 and the adjusting component 3 can drive the adjusting tube 2 to move inside the connecting tube 1, so that the length between the adjusting tube 2 and the connecting tube 1 can be adjusted. The above setting makes it possible to adjust the height between the inner arm and the outer arm connected together by the connecting tube 1 and the adjusting tube 2. At the same time, the overall length of the inner arm and the outer arm does not need to be set too long. When the inner arm and the outer arm are folded together, the adjusting tube 2 can be moved to the inside of the connecting tube 1. The above setting makes it possible for the components on the crane tube to not occupy too much space after being folded together, so that it is more convenient to transport the crane tube; 2. The two connecting rods 502 are pulled by the pulling plate 505 to lock The tooth block 503 can squeeze the spring 504 backward and move directly out of the inside of the storage groove 402, so that the locking tooth block 503 no longer limits and locks the rotating tube 401, and then the rotating tube 401 is rotated to complete the adjustment of the length between the adjusting tube 2 and the connecting tube 1. The above arrangement enables the locking tooth block 503 to lock the rotating tube 401 by driving the tooth groove 403 under the push of the spring 504, so that the adjusted adjusting tube 2 will not change its position at will, and when the rotating tube 401 is rotated, the pull plate 505 can be directly pulled to release the lock of the rotating tube 401, which is relatively convenient to operate.
