Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, specifically to a new type of high-voltage transmission line lifting device. Background Technology

[0002] With the rapid development of the power industry, the demand for the construction and operation and maintenance of ultra-high voltage (UHV) transmission lines has increased significantly. In the erection and operation and maintenance of high-voltage and UHV transmission lines, transmission line lifting devices are crucial tools in power construction. Traditional lifting devices have simple structures and poor flexibility, making them difficult to meet the requirements of safe, efficient, and flexible construction in modern power grids. For example, Chinese Patent CN202856241 U discloses a detachable six-wire lifting device, which connects the lifting device body to the hook via a threaded connection, forming a detachable structure. During use, the hook is attached to the lifting device body to lift the line; after use, the hook and lifting device body are detached, making operation simple and convenient to carry. However, in practical use, this solution makes moving the conductor position inconvenient, increasing the difficulty and safety risks for construction workers working at heights. Furthermore, this structure cannot effectively lock the conductor, thus posing a risk of the conductor slipping during construction, increasing the danger of the construction process. Utility Model Content

[0003] To address one or more shortcomings of the existing technology, this utility model provides a novel high-voltage transmission line lifting device. Through the cooperation of the support base and the rotating shaft, the conductor can be flexibly rotated on both sides of the lifting device during use. This not only improves the flexibility of construction but also reduces the construction difficulty and safety hazards caused by improper conductor positioning. Moreover, through the cooperation of the lifting hook and the handle, construction personnel can quickly and safely complete the tightening and clamping operation of the conductor when working at height, preventing the conductor from slipping and improving the safety of high-altitude operations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel high-voltage transmission line lifting device includes an installation body, on both sides of which support seats are fixedly installed. A rotating shaft is inserted into the inside of each support seat and is rotatably connected to the support seat. A support rod is rotatably connected to the end of the rotating shaft. A lifting hook for receiving the conductor is provided at the bottom end of the support rod. A limiting post for locking the conductor is inserted into one side of the lifting hook.

[0006] As a further implementation, a boom is installed on the top of the mounting body, and a fixing plate is fixedly connected to the bottom of the boom. The boom is fixedly connected to the mounting body through the fixing plate; a lifting ring is installed on the top of the boom.

[0007] As a further implementation, the mounting body has bolt holes in the middle, the fixing plate has through holes corresponding to the bolt holes, and the mounting body and the boom are fixedly connected by bolts.

[0008] As a further implementation, a bearing is snapped into the inside of the support seat, and a pipe joint is snapped into the inner ring of the bearing. The pipe joint is fixedly connected to the rotating shaft. The support seat, bearing, pipe joint, and rotating shaft are all coaxially arranged.

[0009] As a further implementation, the pipe fitting and the rotating shaft are fixedly connected by a pin.

[0010] As a further implementation, threaded posts are fixedly provided at both ends of the rotating shaft, and locking plates are fixedly provided on both sides of the top of the support rod. The locking plates have round holes that are rotatably connected to the threaded posts.

[0011] As a further implementation, the support is disposed below the mounting body, and the support is fixedly connected to the mounting body by bolts.

[0012] As a further implementation, a limiting hole is provided at the bottom end of the support rod, and the support rod is rotatably connected to the lifting hook through the limiting hole.

[0013] As a further implementation, the inner side of the lifting hook is provided with an anti-slip rubber pad to increase the friction between the lifting hook and the wire, and also to protect the wire and prevent damage to the wire.

[0014] As a further implementation, a handle is installed on the outside of the limiting post, and a locking block is provided at one end of the handle near the limiting post, the locking block being connected to the limiting post; an end cap is provided at the other end of the handle.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a support base and a rotating shaft for rotatable connection. During high-altitude operations, the lifting hook can be operated to drive the conductor to rotate left and right inside the lifting device, which allows for more flexible movement or adjustment of the conductor's position. This effectively reduces the operational difficulty of high-altitude power construction and also reduces safety hazards caused by improper conductor positioning, thus improving construction safety. At the same time, the combination of the lifting hook and the limiting post can quickly tighten and lock the conductor inside the lifting device, preventing the conductor from slipping during high-altitude operations. This design offers high safety and convenient operation.

[0017] 2. This utility model connects the support base and the rotating shaft through the insertion of bearings and pipe joints. The rotating shaft can rotate relative to the support base, thereby realizing the flexible adjustment of the support rod and the wire. Attached Figure Description

[0027] Example 1

[0028] In one typical embodiment of this application, a novel high-voltage transmission line lifting device is provided, such as... Figure 1-5As shown, the device includes an installation body 1, on both sides of which support seats 2 are fixedly installed. A rotating shaft 3 is inserted into the inside of the support seat 2 and is rotatably connected to the support seat 2. A support rod 4 is rotatably connected to the end of the rotating shaft 3. A wire hook 5 for holding the wire is provided at the bottom end of the support rod 4. A limiting post 17 for locking the wire is inserted into one side of the wire hook 5.

[0029] Specifically, such as Figure 1 As shown, a boom 6 is mounted on the top of the main installation body, and a lifting ring 19 is fixedly mounted on the top of the boom 6 for connection to the construction shackle, ensuring the stability and safety of the equipment during high-altitude operations. Combined with... Figure 2 As shown, the mounting body 1 has bolt holes 9 in the middle, and the bottom sides of the boom 6 are fixedly connected with fixing plates 18. The fixing plates 18 have through holes corresponding to the bolt holes. The mounting body and the boom are fixedly connected by bolts through the bolt holes 9 and the through holes and locked with nuts.

[0030] Specifically, such as Figure 1-3 As shown, the support base 2 is installed below the mounting body 1. A through-hole is longitudinally formed on the support base 2, through which the fixing bolt 9 passes to and is fixedly connected to the mounting body 1, thereby fixing the support base to the bottom of the mounting body. To allow the wire to rotate within the device during construction for flexible adjustment of its position, such as... Figure 3 As shown, a bearing 10 is internally fitted into the support seat 2. The outer ring of the bearing is fixedly installed inside the support seat, and a pipe joint 11 is fitted into the inner ring of the bearing 10. The pipe joint 11 is fixedly connected to the rotating shaft 3, thereby allowing the rotating shaft 3 to rotate relative to the bearing seat 2. The support seat 2, bearing 10, pipe joint 11, and rotating shaft 3 are all coaxially arranged. In this embodiment, the side walls of the pipe joint 11 and the rotating shaft 3 are provided with matching pin holes. Pins 12 pass through the side of the pipe joint 11 and the rotating shaft 3 to fix them together. Both ends of the rotating shaft 3 extend beyond the pipe joint 11 for connection to the support rod 4.

[0031] Specifically, such as Figure 3-4 As shown, threaded posts 13 are fixedly installed on both end faces of the rotating shaft 3. The top of the support rod 4 has a recessed structure, and locking plates 14 are fixedly provided on both sides. The locking plates 14 have through holes, and the locking plates 14 on both sides are connected to the threaded posts 13 through the holes, thereby realizing the rotational connection between the support rod 4 and the rotating shaft 3. A through limiting hole 15 is provided on the bottom side of the support rod 4, and the support rod 4 is rotatably connected to the lifting hook 5 through the limiting hole 15.

[0032] Specifically, such as Figure 4-5As shown, the top of the lifting hook 5 is provided with a hinge seat, which is connected to the limiting hole by a pin, thereby hinged the lifting hook 5 to the support rod 4, so that the lifting hook 5 can rotate relative to the support rod 4, which facilitates the adjustment of the wire position and reduces the operational difficulty of high-altitude construction.

[0033] like Figure 1 , 5 As shown, the lifting hook 5 is installed at the bottom end of the support rod 4. The lifting hook 5 is a curved hook structure with the opening facing upwards. During use, the wire is placed inside the lifting hook. In this embodiment, the inner side of the lifting hook 5 is provided with an anti-slip rubber pad 16, which can increase the friction between the wire and the lifting hook, and avoid damage to the wire, thus ensuring the safety and stability of the power construction process.

[0034] In addition, to lock the guide during use, in this embodiment, a limiting post 17 is inserted into one side of the lifting hook 5. The limiting post 17 passes laterally through the opening of the lifting hook to clamp the wire. Figure 5 As shown, a handle 7 is installed on the outer side of one end of the limiting post 17. A locking block 20 is fixedly installed on the end of the handle near the limiting post. The shape of the locking block 20 matches the shape of the limiting hole on the limiting post. The locking block 20 is inserted into the limiting post 17 to connect the handle and the limiting post. Rotating the handle 7 can drive the limiting post 17 to rotate, thereby adjusting the opening size of the lifting hook 5 and securing the wire. The other end of the handle is provided with an end cap 21, which can increase the friction at the tail of the handle to prevent the hand from slipping in wet or sweaty conditions.

[0035] The operating principle of this embodiment is as follows:

[0036] First, place the wire to be installed between the two lifting hooks 5, and adjust the position of the lifting hooks 5 to ensure they can tightly grip the wire. Then, by cooperating with the locking block 20 and end cap 21 on the handle 7, rotate the handle 7 to make the anti-slip rubber pad 16 inside the lifting hook 5 make tight contact with the wire, thus locking the wire. Next, hoist the device to the designated high-altitude working position using the lifting ring 19 on the boom 6. Finally, by cooperating with the support base 2 and the rotating shaft 3, rotating the rotating shaft 3 causes the support rod 4 to drive the lifting hooks 5 and the wire to rotate according to the construction requirements, making the operation more flexible and safer.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Those skilled in the art should understand that this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
