[0035] A gas cylinder lifting tool for lifting a gas cylinder 5, such as Figures 1-3As shown, the hoisting tool comprises a top end lifting bar 1, a protective sleeve 2 and a flange 3, the top end lifting bar 1 comprises a mounting portion 9 and a through hole 8 arranged on the body of the top end lifting bar 1, the two ends of the gas cylinder 5 are respectively a top end cylinder port 51 and a tail end cylinder port 52 with external threads, the protective sleeve 2 is sleeved on the outer periphery of the side of the top end cylinder port 51 towards the cylinder body of the gas cylinder 5, the through hole 8 passes through the top end cylinder port 51 and is sleeved on the outer periphery of the protective sleeve 2, the flange 3 is connected with the outer periphery of the side of the top end cylinder port 51 away from the cylinder body, the top end lifting bar 1 is located between the cylinder body and the flange 3, and the flange 3 blocks the through hole 8. The mounting portion 9 is connected with the lifting appliance 6. Since the cylinder body of the gas cylinder 5 is smooth, it is difficult to directly lift by the lifting appliance 6, the top end lifting bar 1 is connected with the lifting appliance 6, the lifting appliance 6 is prevented from directly acting on the gas cylinder 5, the gas cylinder 5 is effectively protected under the premise of being able to be hoisted and transported. The external thread of the gas cylinder 5 has a certain strength, the hoisting tool of the utility model is arranged at the external thread, the internal thread of the gas cylinder 5 will not be abraded and subjected to external force, and the sealing property of the gas cylinder 5 is beneficial. The lifting appliance 6 is straightened under the action of the crown block 7 and lifts the gas cylinder 5, and the hoisting and transportation of the gas cylinder 5 are completed. In the process of lifting the gas cylinder 5, the flange 3 is blocked, not only the top end lifting bar 1 can be prevented from falling off, the use safety is improved, but also the action load of hoisting is transmitted to the flange 3, the abrasion of the gas cylinder 5 is reduced, and the gas cylinder 5 is effectively protected.

[0036] As a preferred example of the utility model, as shown in the drawings, Figures 8-11 As shown, the protective sleeve 2 and the top end cylinder port 51 are threadedly connected, and the flange 3 and the top end cylinder port 51 are threadedly connected, so that the protective sleeve 2 and the flange 3 are arranged on the outer periphery of the top end cylinder port 51 and play a role in protecting the external thread of the top end cylinder port 51.

[0037] Further, the gas cylinder 5 is cylindrical, and in order to better adapt to the top end cylinder port 51, the protective sleeve 2 and the flange 3 are both annular.

[0038] As a preferred example of the utility model, the hoisting tool further comprises a bottom end lifting bar 4, the bottom end lifting bar 4 comprises a mounting portion 9 and a through hole 8 arranged on the body of the bottom end lifting bar 4, and the through hole 8 of the bottom end lifting bar 4 is sleeved on the outer periphery of the tail end bottle mouth 52. The top end lifting bar 1 and the bottom end lifting bar 4 form a lifting bar. For the gas cylinder 5 with light weight, only the top end lifting bar 1 is arranged, and the hoisting of the gas cylinder 5 is completed by the interaction of the top end lifting bar 1, the protective sleeve 2 and the flange 3. For the gas cylinder 5 with heavy weight and large volume, the top end lifting bar 1 and the bottom end lifting bar 4 are arranged simultaneously, the hoisting stability of the gas cylinder 5 is improved, and the swing of the gas cylinder 5 in the hoisting process is reduced. In the hoisting process, the top end lifting bar 1 located at the top end of the gas cylinder 5 plays a main role, and the bottom end lifting bar 4 located at the tail end of the gas cylinder 5 plays an assisting role. The top end lifting bar 1 and the bottom end lifting bar 4 cooperate with each other, and different forms of hoisting, such as parallel hoisting, vertical hoisting and temporary inclined hoisting, can be completed, the versatility is good, and different use scenes are suitable.

[0039] Considering the adaptability of the top end lifting bar 1 and the top end bottle mouth 51 with different diameters, the top end lifting bar 1 is not provided with internal threads, and therefore the top end lifting bar 1 is not directly connected with the top end bottle mouth 51. The protective sleeve 2 and the flange 3 are directly connected with the top end bottle mouth 51. When it is necessary to match the top end bottle mouth 51 with different diameters, only the protective sleeve 2 and the flange 3 need to be replaced, and the top end lifting bar 1 can be arranged between the bottle body and the flange 3, and the top end lifting bar 1 with large size and large volume does not need to be replaced, which is favorable for reducing the cost. In order to better protect the external threads of the gas cylinder 5 and avoid the top end lifting bar 1 from shaking and colliding with the external threads of the top end bottle mouth 51 in the hoisting process, the outer periphery of the top end bottle mouth 51 is connected with the protective sleeve 2 and the flange 3 in the direction from the bottle body to the top end bottle mouth 51, and the protective sleeve 2 and the flange 3 can cover all the external threads of the top end bottle mouth 51, and the top end lifting bar 1 is prevented from directly contacting the external threads.

[0040] Since the bottom end lifting bar 4 plays an assisting role, and the external threads have a certain strength, the bottom end lifting bar 4 does not need to be used in cooperation with the protective sleeve 2. At the same time, for the bottom end lifting bar 4, the bottle body can block the bottom end lifting bar 4 from falling off, and therefore the bottom end lifting bar 4 does not need to be used in cooperation with the flange 3.

[0041] Further, the through hole 8 of the bottom end lifting bar 4 is provided with internal threads on the inner side, and the bottom end lifting bar 4 is threadedly connected with the tail end bottle mouth 52. Not only can the bottom end lifting bar 4 be positioned, but also the bottom end lifting bar 4 can be prevented from colliding with the external threads of the tail end bottle mouth 52.

[0042] Considering the balance and stability of hoisting, two mounting portions 9 are arranged on the top end lifting bar 1 and the bottom end lifting bar 4 respectively.

[0043] Specifically, the mounting portion 9 comprises a mounting hole 10 and a mounting hole 11 arranged on the top end lifting bar 1 and the bottom end lifting bar 4 respectively. Figures 4-5In the specific embodiment, the lifting bar is provided with a through hole 8, and two mounting portions 9 are arranged on the lower side of the lifting bar, wherein the mounting portion 9 is a lifting ring 10. The lifting tool 6 passes through the lifting ring 10 and is used for lifting the gas cylinder 5. The lifting ring 10 itself can play a blocking and limiting role to prevent the lifting tool 6 from falling off. Compared with the lifting ring 10 arranged on the side of the lifting bar close to the cylinder body, the lifting ring 10 arranged on the lower side of the lifting bar, i.e. the side of the lifting bar away from the cylinder body, can reserve sufficient space for the installation of the lifting tool 6 and the lifting ring 10, and prevent the lifting tool 6 from easily colliding with the tail of the cylinder body when the lifting bar and the lifting tool 6 are used together.

[0044] Alternatively, the specific embodiment is as follows: Figures 6-7 In the specific embodiment, the lifting bar is provided with a through hole 8, and two mounting portions 9 are arranged on the lower side of the lifting bar, wherein the mounting portion 9 is a lifting ring 10. The lifting tool 6 passes through the lifting ring 10 and is used for lifting the gas cylinder 5. The lifting ring 10 itself can play a blocking and limiting role to prevent the lifting tool 6 from falling off. Compared with the lifting ring 10 arranged on the side of the lifting bar close to the cylinder body, the lifting ring 10 arranged on the lower side of the lifting bar, i.e. the side of the lifting bar away from the cylinder body, can reserve sufficient space for the installation of the lifting tool 6 and the lifting ring 10, and prevent the lifting tool 6 from easily colliding with the tail of the cylinder body when the lifting bar and the lifting tool 6 are used together.

[0045] Further, the lifting ring 10 and the lifting bar body are rotationally connected, which is used for adjusting the direction during lifting to follow the rotating direction of the gas cylinder 5, improve flexibility, and avoid the lifting tool 6 from being twisted.

[0046] The lifting tool 6 comprises a hook and a cable, the hook and the cable are connected, the hook is used for hooking the mounting portion 9, and the cable is connected with the overhead crane 7. The hook can be used for quickly and conveniently hooking the mounting portion 9, and the overhead crane 7 is used for providing a power source for lifting.

[0047] Specifically, the protective sleeve 2 is made of nylon material and has high wear resistance, thereby prolonging the service life. The lifting bar and the flange 3 are made of steel and have high strength, thereby being capable of bearing large load during lifting.

[0048] The gas cylinder lifting tool has the advantages that the fixing and load bearing mode is adopted at the outer thread of the bottle mouth, damage to the inner thread of the bottle mouth is avoided, the safety of lifting operation is improved, and the risk of damage to the sealing performance of the bottle mouth is reduced. Meanwhile, the gas cylinder lifting tool can be used for lifting an overlong, overweight or oversized diameter large-size overweight steel seamless gas cylinder, has a wide use range, and can be used for parallel lifting, vertical lifting and temporary inclined lifting, and has good versatility.
