Description

Technical Field

[0001] This utility model relates to the field of lifting equipment, and in particular to a lifting device. Background Technology

[0002] The integrated SF6 gas handling equipment is a relatively large mobile device that integrates SF6 recovery, purification, and recharging services. It is primarily used for the recovery and reuse of SF6, a protective gas in switchgear of the State Grid. According to relevant regulations, SF6 gas cannot be directly released into the atmosphere and must be recovered and treated. After treatment, the SF6 meets relevant standards and can be reused in electrical switches. High-voltage switches in the power grid are often distributed at various nodes in substations and power consumption sites, resulting in a dispersed geographical distribution. Therefore, the integrated SF6 gas handling equipment must be mobile to facilitate operations.

[0003] Because the SF6 gas handling integrated equipment operates in various locations and frequently interacts with equipment such as SF6 pre-recovery systems and 40-liter liquefied petroleum gas cylinders, and these heavy devices are difficult for humans to lift, the applicant designed the lifting device described in this application. This lifting device is installed on the SF6 gas handling integrated equipment to lift various equipment around the SF6 gas handling integrated equipment, thereby replacing manual handling work.

[0030] This invention proposes a lifting device that can be installed on a sulfur hexafluoride gas handling integrated machine to lift various equipment around the SF6 gas handling integrated machine, thereby replacing manual handling work and saving time and effort.

[0031] Specifically, in one embodiment of the utility model, such as Figure 1 and Figure 2 As shown, the lifting device includes a first mounting frame 3 and a second mounting frame 4 arranged at intervals. The first mounting frame 3 and the second mounting frame 4 are detachably and fixedly connected to the integrated sulfur hexafluoride gas handling unit. A rotating cylinder 2 that rotates around a vertical axis is installed on the first mounting frame 3 and the second mounting frame 4. For example, an end face bearing is installed between the bottom of the rotating cylinder 2 and the first mounting frame 3, and radial bearings are installed between the lower side of the rotating cylinder 2 and the first mounting frame 3, and between the upper side of the rotating cylinder 2 and the second mounting frame 4. A drive motor 1, which is connected to the rotating cylinder 2, is installed on the first mounting frame 3 or the second mounting frame 4. The drive motor 1 drives the rotating cylinder 2 to rotate on the first mounting frame 3 and the second mounting frame 4. Specifically, as shown... Figure 1 and Figure 2 As shown, a geared disc 10 is coaxially fixedly mounted on the rotating cylinder 2. The geared disc 10 is connected to the drive motor 1 for transmission. The drive motor 1 drives the geared disc 10 to drive the rotating cylinder 2 to rotate.

[0032] In this embodiment, the rotating cylinder 2 is vertically slidably connected to a lifting cylinder 5, and the lifting cylinder 5 is connected to a lifting device 15. The lifting device 15 drives the lifting cylinder 5 to move up and down relative to the rotating cylinder 2. The lifting cylinder 5 is fixedly connected to a bracket 7, and the bracket 7 is connected to a fixed beam 8. A lifting rope 11 is wound on the fixed beam 8. One end of the lifting rope 11 is connected to a lifting hook 9, and the other end of the lifting rope 11 is connected to a hoist 6. The hoist 6 drives the lifting hook 9 to lift and lower various equipment through the lifting rope 11.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the lifting cylinder 5 is vertically slidably inserted into the upper end of the rotating cylinder 2 and is coaxial with the rotating cylinder 2; the rotation of the rotating cylinder 2 drives the lifting cylinder 5 to rotate synchronously, and the hoist 6 is fixedly connected to the lifting cylinder 5; the bracket 7 is horizontally arranged, one end of the bracket 7 along its length is fixedly connected to the upper end of the lifting cylinder 5, and the other end of the bracket 7 along its length is horizontally slidably connected or fixedly connected to the fixed beam 8. The fixed beam 8 is provided with an elongated hole 12 extending along the length of the bracket 7, and the bottom surface of the elongated hole 12 extends along the bracket. 7. Multiple locking holes 13 are spaced apart along the length direction. A wheel axle 19 is rotatably mounted in one of the locking holes 13. A fixed pulley 14 is mounted on the wheel axle 19. The wheel axle 19 can move upwards to leave the locking hole 13 and enter the elongated hole 12. The wheel axle 19 can slide in the elongated hole 12 and fall into other locking holes 13. This design allows adjustment of the position of the fixed pulley 14, and consequently, the position of the lifting hook 9, facilitating the lifting of different equipment. The lifting rope 11 is wound around the fixed pulley 14. The lifting hook 9 is located below the fixed beam 8. Figure 1 and Figure 2 As shown, after the hoist 6 is started, it winds up or unwinds the hoisting rope 11, which in turn drives the hoisting hook 9 to lift and lower the hoisting equipment. In addition, the drive motor 1 can be controlled to rotate the hoisting hook 9 around the rotating cylinder 2 to adjust the position of the hoisting hook 9 and to lift heavy objects around the rotating cylinder 2 as needed. The lifting device 15 can also be controlled to lift the support 7, the fixed beam 8, and the lifting cylinder 5 to adjust the initial height of the hoisting hook 9 off the ground, so as to facilitate the hoisting hook 9 to lift various equipment. After the lifting work is completed, the lifting cylinder 5 is lowered and reset, reducing the volume of the hoisting device, making the hoisting device suitable for lifting heavy objects on mobile equipment such as truck body platforms and equipment chassis.

[0034] The lifting device in this embodiment solves the problem of lifting and moving peripheral equipment of the integrated sulfur hexafluoride (SF6) gas handling equipment, greatly facilitating lifting operations. Previously, different handling and lifting tools or equipment had to be carried manually to lift the equipment, which was not only time-consuming and labor-intensive but also expensive. The lifting device in this embodiment is easy to operate and reliable, improving work efficiency and greatly facilitating the engineering application of the integrated SF6 gas handling equipment. It also helps to increase the market share of the integrated SF6 gas handling equipment. Although the lifting device is an auxiliary function of the integrated SF6 gas handling equipment, it effectively solves the problem of adjusting peripheral equipment at different working points, making it convenient, fast, and improving handling efficiency while reducing many expenses. It has a promising prospect in the domestic market.

[0035] Specifically, such as Figure 1 and Figure 2As shown, the lifting device 15 is located inside the rotating cylinder 2 and is coaxially and rotatably connected to the rotating cylinder 2 and the lifting cylinder 5. The lower end of the lifting device 15 extends out of the rotating cylinder 2 and is fixedly connected to the mounting bracket 3. Of course, in other embodiments, the lower end of the lifting device 15 may not extend out of the rotating cylinder 2. In this case, the lower end of the lifting device 15 is rotatably connected to the rotating cylinder 2 through the end face bearing.

[0036] Furthermore, to enhance the stability of the jacking device 15 and ensure its smooth lifting of the lifting cylinder 5, such as... Figure 2 As shown, a limit ring 17 is coaxially arranged between the lifting device 15 and the rotating cylinder 2. The limit ring 17 is rotatably connected to the lifting device 15 and the rotating cylinder 2. In addition, to ensure that the lifting device 15 reliably lifts the lifting cylinder 5 without affecting the rotation of the lifting cylinder 5, as shown... Figure 2 As shown, a support plate 18 is fixedly installed inside the lifting cylinder 5, and the support plate 18 is rotatably connected to the lifting device 15.

[0037] In this embodiment, as Figure 2 As shown, dust covers 16 are provided at the slewing connection points between the mounting bracket 3 and the rotating cylinder 2. This design can prevent dust from entering the slewing connection points between the mounting bracket 3 and the rotating cylinder 2.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
