[0002] Liquefied petroleum gas is one of the petrochemical products, referred to as LPG, which refers to a colorless, volatile gas that can be liquefied or stored and transported in liquid phase under appropriate ambient temperature and pressure. It mainly comes from the by-product gas of various processing equipment during the petroleum processing, and some of it comes from natural gas. Liquefied petroleum gas can be used in various fields such as chemical industry and fuel, and has been widely used in all aspects of human life.

[0003] When operators perform sampling and analysis of liquefied gas, they often use auxiliary sampling tools to fix the sampling liquefied gas cylinder, so as to facilitate the operators to sample the liquefied gas in the bottle.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, the utility model provides a rotary inverted bottled liquefied gas auxiliary injection tool, comprising:

[0027] A bottom plate 1, the front and rear sides of the upper surface of the bottom plate 1 are fixedly connected to a support plate 2, the upper side of the inner surface of the support plate 2 is movably connected to a mounting box 3, the outer surfaces of the front and rear sides of the mounting box 3 are fixedly connected to a connecting shaft 4, the outer ends of the connecting shaft 4 penetrate the support plate 2 and extend to the front and rear sides of the support plate 2 respectively;

[0028] A first gear 5, the first gear 5 is fixedly sleeved on the front side of the outer surface of the connecting shaft 4, and the rear surface of the first gear 5 is movably connected to the front surface of the supporting plate 2;

[0029] A locking mechanism, which is arranged on the outer surface of the support plate 2;

[0030] Among them, the locking mechanism includes a No. 1 motor 7, which is fixedly installed on the front side of the right surface of the support plate 2, and the No. 1 motor 7 is located in front of the installation box 3. The other end of the output shaft of the No. 1 motor 7 is fixedly sleeved with a round shaft 8, and the outer surface of the round shaft 8 is fixedly sleeved with a rotating rod 9 located on the front side of the support plate 2. The inner surface of the left side of the rotating rod 9 is movably connected with a gear block 6, and the outer surface of the top of the gear block 6 is meshed with the outer surface of the No. 1 gear 5, and the rear surface of the gear block 6 is movably connected to the outer surface of the support plate 2. The operation of the No. 1 motor 7 causes the round shaft 8 and the rotating rod 9 to rotate and drives the gear block 6 to move up and down.

[0031] Due to the design of the support plate 2, the installation box 3 and the connecting shaft 4, the installation box 3 can rotate as a whole. When the No. 1 motor 7 is running, the circular shaft 8 and the rotating rod 9 will rotate. At this time, the gear block 6 will move upward under the drive of the left inner surface of the rotating rod 9. When the gear block 6 and the No. 1 gear 5 are engaged, the rotation of the installation box 3 as a whole will be locked, so that the installation box 3 as a whole can be maintained at a specific tilt angle.

[0032] Among them, the outer surfaces of the left and right sides of the gear block 6 are fixedly connected with a No. 1 limit block 10, the outer surface of the No. 1 limit block 10 is movably connected to the outer surface of the support plate 2, the outer surface of the No. 1 limit block 10 is movably connected to a limit plate 11 located under the No. 1 gear 5, and the rear surface of the limit plate 11 is fixedly connected to the outer surface of the support plate 2.

[0033] Due to the design of the first limiting block 10 and the limiting plate 11, the stability of the moving direction of the gear block 6 is ensured.

[0034] A sleeve plate 12 is fixedly connected to the left side of the upper surface of the installation box 3 , and a crank handle 13 is fixedly sleeved on the rear side of the outer surface of the connecting shaft 4 .

[0035] The design of the crank 13 facilitates the operator to rotate the installation box 3 as a whole.

[0036] Among them, the upper surface of the installation box 3 is fixedly connected to the No. 2 motor 14 located on the right side of the sleeve 12, and the other end of the output shaft of the No. 2 motor 14 is fixedly sleeved with a rotating shaft 15. The bottom end of the outer surface of the rotating shaft 15 passes through the installation box 3 and extends to the interior of the installation box 3. The outer surface of the rotating shaft 15 and the inner surface of the installation box 3 are movably sleeved.

[0037] When the second motor 14 is running, the rotating shaft 15 starts to rotate.

[0038] Among them, the outer surface of the rotating shaft 15 is fixedly sleeved with a No. 2 gear 16 located inside the installation box 3, the outer surface of the No. 2 gear 16 is meshingly connected with a ring gear 17 located on the left side inside the installation box 3, the inner surface of the ring gear 17 is movably connected with a No. 2 limit block 18, and the lower surface of the No. 2 limit block 18 is fixedly connected to the inner surface of the installation box 3.

[0039] The second gear 16 rotates together with the rotating shaft 15 , and the rotation of the second gear 16 also drives the ring gear 17 to start rotating.

[0040] Among them, the inner surface of the installation box 3 is fixedly connected to a circular plate 19 located on the inner side of the ring gear 17, and the outer surface of the circular plate 19 is movably connected to a fixed block 22. There are three fixed blocks 22, and the other ends of the three fixed blocks 22 all penetrate the circular plate 19 and extend to the inner side of the circular plate 19.

[0041] The three circular plates 19 can fix the liquefied gas cylinder.

[0042] The inner surface of the gear ring 17 is fixedly connected with an articulated block 20 , and the inner surface of the articulated block 20 is articulated with connecting rods 21 . There are three connecting rods 21 , and the other ends of the three connecting rods 21 are respectively articulated with the outer ends of the three fixed blocks 22 .

[0043] When the gear ring 17 and the hinge block 20 rotate, the three connecting rods 21 rotate, and the other ends of the three connecting rods 21 drive the three fixing blocks 22 respectively, so that the three fixing blocks 22 move inward along the inner surface of the circular plate 19 .

[0044] The working principle and use process of this utility model:

[0045] First, the operator places the liquefied natural gas cylinder between the three fixed blocks 22 and starts the No. 2 motor 14. As the No. 2 motor 14 runs, the rotating shaft 15 and the No. 2 gear 16 will rotate. At this time, the ring gear 17 as a whole will rotate under the limit of the No. 2 limit block 18 and the drive of the No. 2 gear 16. The overall rotation of the ring gear 17 will cause the three hinge blocks 20 to start driving the three connecting rods 21 respectively, which makes the other ends of the three connecting rods 21 drive the three fixed blocks 22 respectively, so that the three fixed blocks 22 move along the inner surface of the circular plate 19 toward the outer surface of the liquefied gas cylinder. Finally, when the three fixed blocks 22 contact the outer surface of the cylinder, the cylinder will be fixed in the current position.

[0046] Then the operator starts the No. 1 motor 7. The operation of the No. 1 motor 7 will cause the circular shaft 8 and the rotating rod 9 to rotate. The rotation of the rotating rod 9 will drive the tooth block 6, so that the tooth block 6 and the No. 1 limit block 10 begin to move downward along the inner surface of the limit plate 11. When the tooth block 6 is out of engagement with the outer surface of the No. 1 gear 5, the rotation lock of the installation box 3 as a whole will be released. At this time, the operator can rotate the crank handle 13 to make the installation box 3 as a whole start to rotate around the connecting shaft 4 as the axis, until the installation box 3 as a whole and the liquefied natural gas cylinder rotate to the angle required by the operator. The operator then starts the No. 1 motor 7 to make the tooth block 6 mesh with the No. 1 gear 5 again, so that the liquefied natural gas cylinder is fixed at the current angle, which is convenient for the operator's next sampling and analysis work.
