Description

Technical Field

[0001] The utility model relates to the technical field of tool pulleys for live working on overhead power transmission lines, in particular to a tool pulley for live working on overhead power transmission lines. Background Art

[0002] The overhead transmission line live working tool pulley is a commonly used tool in live working during transmission line maintenance. It is also a fall prevention device hung on the conductor. Its main function is to connect and remove the ladder to the conductor when using the ladder on the transmission line.

[0003] When in use, the overhead transmission line live working tool pulley can be lifted onto the conductor by a drone, and then the entire overhead transmission line live working tool pulley can be locked on the conductor through a locking structure. However, the spring of most locking structures is directly set on the outside, which causes the spring to get stuck when locking. The subsequent processing is more troublesome, and it is more difficult to drop the line, which is very inconvenient. Utility Model Content

[0004] To this end, the utility model provides a tooling pulley for live working on overhead power transmission lines to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] According to a first aspect of the present invention, a tooling pulley for live working on overhead transmission lines comprises:

[0007] A pulley is mounted on the upper end of the mounting frame via a bearing, and a connecting plate is mounted on the outer side of the right end of the mounting frame. A conductor blade is disposed on the outer side of the lower end of the connecting plate, and a first fixing screw is disposed in the middle of the connection between the conductor blade and the connecting plate.

[0008] A mounting rod is provided inside the connection between the mounting frame and the connecting plate, and a locking rod is integrally fixedly installed on the outer side of the lower end of the mounting rod, and a spring is provided on the outer end of the mounting rod, which is also located inside the connection between the mounting frame and the connecting plate;

[0009] The mounting rod has a hanging ring fixedly mounted on the outer side of the upper end thereof.

[0010] Furthermore, a prefabricated through hole is provided inside the lower end of the mounting frame, and the inner side of the lower end of the mounting frame is inclined.

[0011] Furthermore, a second fixing screw is provided through the interior of the connecting plate, and a limiting column located on the outside of the mounting rod is fixedly installed on the outer side of the upper end of the connecting plate.

[0012] Furthermore, the connecting plate and the mounting frame form a detachable structure through a second fixing screw, and the lower end of the connecting plate is arranged at an angle.

[0013] Furthermore, a mounting cavity is provided inside the connection between the mounting frame and the connecting plate, and the spring is located in the mounting cavity.

[0014] Furthermore, the upper end of the conductor blade is located inside the lower end of the connecting plate.

[0015] The utility model has the following advantages:

[0016] 1. Through the connecting plate, the connecting plate is fixed to the outer side of the right end of the mounting frame by the second fixing screw. At this time, the connecting plate can cover the spring located in the mounting frame, so that the spring is built into the mounting cavity, thereby preventing the spring from getting stuck when locking;

[0017] 2. Through the wire blade, the first fixing screw fixes the wire blade to the outer side of the lower end of the connecting plate. The wire blade is extended and tilted, and is located at the upper end of the opening at the lower end of the mounting frame, making it easier to drop the wire;

[0018] 3. Through the locking rod, the lower end of the locking rod can be inserted into the mounting bracket to realize the locking function of the opening of the mounting bracket to prevent the mounting bracket from slipping off the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 2 This is a front cross-sectional view of the mounting rod and spring connection of a tool pulley for live working on overhead power lines provided in some embodiments of the present invention.

[0021] In the figure: 1. mounting frame, 2. pulley, 3. connecting plate, 4. wire blade, 5. first fixing screw, 6. second fixing screw, 7. mounting rod, 8. locking rod, 9. spring, 10. hanging ring, 11. limiting column, 12. prefabricated through hole, 13. mounting cavity. DETAILED DESCRIPTION

[0022] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention. Example

[0023] like Figures 1 to 2 The cam 2 is fixed on the upper end of the support frame 1 and the support frame 1 is fixed on the support frame 1, so that the cam 2 can be fixed on the support frame 1 and the support frame 1 is fixed on the support frame 1.

[0024] The mounting rod 7 is arranged inside the connection between the mounting frame 1 and the connecting plate 3, and a locking rod 8 is integrally fixedly installed on the outer side of the lower end of the mounting rod 7. A spring 9 is provided on the outer end of the mounting rod 7, which is also located inside the connection between the mounting frame 1 and the connecting plate 3. A hanging ring 10 is fixedly installed on the outer side of the upper end of the mounting rod 7. The hanging ring 10, the mounting rod 7 and the locking rod 8 are arranged in sequence from top to bottom. Before hanging, the drone is lifted as a whole by the hanging ring 10. At this time, the mounting rod 7 and the locking rod 8 both move upward, and the lower end of the locking rod 8 is separated from the mounting frame 1, and the spring 9 is compressed;

[0025] When the drone is hung on the wire as a whole, the drone is separated from the hanging ring 10. At this time, the spring 9 generates a force to restore the deformation, thereby driving the mounting rod 7, the locking rod 8 and the hanging ring 10 to move downward. At this time, the lower end of the locking rod 8 can be reinserted into the mounting frame 1, realizing the locking function of the opening of the mounting frame 1, and preventing the mounting frame 1 from easily slipping off the wire;

[0026] A second fixing screw 6 is provided through the interior of the connecting plate 3, and a limiting column 11 located on the outside of the mounting rod 7 is fixedly installed on the outer side of the upper end of the connecting plate 3. A mounting cavity 13 is provided inside the connection between the mounting frame 1 and the connecting plate 3, and the spring 9 is located in the mounting cavity 13. The limiting column 11 can limit the upper end of the mounting rod 7. At the same time, the connecting plate 3 is fixedly installed on the outer side of the right end of the mounting frame 1 by the second fixing screw 6. At this time, the connecting plate 3 can cover the spring 9 located in the mounting frame 1, so that the spring 9 is built into the mounting cavity 13, thereby avoiding the phenomenon that the spring 9 is easily stuck when the lock is dropped.
