Description

Technical Field

[0001] This invention relates to construction equipment for high-voltage transmission lines, specifically to an auxiliary operation platform for spacer bar installation. Background Technology

[0002] Spacer bars are common accessories on power transmission lines, especially overhead high-voltage transmission lines. They are primarily used to split the transmission lines to maintain a certain distance between them, effectively preventing whipping and collisions between lines during severe weather conditions such as strong winds and snow, and suppressing vibrations and oscillations caused by strong winds, thus ensuring the safety and stability of the transmission line. Currently, spacer bars are mainly installed manually by hand. Specifically, after the installation of clamps on tension towers and straight-line towers of overhead transmission lines, workers carry the spacer bars out to install them. The large number of spacer bars installed, the repetitive manual labor, and the high risk and difficulty of working at height severely limit the efficiency of spacer bar installation. Summary of the Invention

[0023] like Figure 1 As shown, an auxiliary work platform for spacer installation provided in this application embodiment includes a profile frame 35, which is spliced ​​from multiple profiles. A base plate 36 is provided at the bottom of the profile frame 35, and the operator can stand on the base plate 36 to perform spacer installation work.

[0024] The profile frame 35 has a walking mechanism on each of its left and right top sides for moving along the upper two conductors of the four-split conductor. The walking mechanism can be flipped to avoid obstacles. The profile frame 35 has a straightening mechanism on each of its left and right sides and below the walking mechanism for moving along the lower two conductors of the four-split conductor and maintaining a fixed distance between the lower two conductors and the upper two conductors. The straightening mechanism can be detached to avoid obstacles. The profile frame 35 also has an auxiliary obstacle-crossing mechanism on each of its left and right sides. The auxiliary obstacle-crossing mechanism is located outside the walking mechanism and has two auxiliary arms 38 that can swing left and right and open and close forward and backward. The two auxiliary arms 38 can cross obstacles and hang on the upper two conductors by swinging and opening and closing.

[0025] Combination Figure 2 The walking mechanism includes a disc motor 1 with a built-in brake. A drive shaft 6 is mounted on the output end of the disc motor 1. Two first hubs 7 are fixed to the drive shaft 6 via positioning pins. Drive wheels 5 are fixed to the first hubs 7 via screws, and the two drive wheels 5 rest on two upper wires respectively. The end of the drive shaft 6 is embedded in a bearing seat 8. The bearing seat 8 is detachably connected to the walking support 9 at the top of the profile frame 35 via a locking pin 10. The motor cover 2 of the disc motor 1 is rotatably connected to the motor cover support 34 at the top of the profile frame 35 via a pin, allowing the motor cover 2 to rotate around the pin at a certain angle. The drive shaft 6 has several equally spaced mounting holes to facilitate adjustment of the distance between the two first hubs 7, thereby adjusting the distance between the two drive wheels 5.

[0026] Of the two traveling mechanisms, the left traveling mechanism is equipped with a brake device 3. The brake device 3 is installed on one side of the disc motor 1 and has a brake disc that rotates with the drive shaft 6. The brake disc mounting bracket is fixed to the motor cover 2 via a connector. The other end of the brake device 3 is connected to the brake handle 4 via an oil pipe. The brake handle 4 is fixed to the profile frame 35. The brake handle 4 controls the brake block to press against the brake disc or move away from the brake disc.

[0027] Combination Figure 3 The winding mechanism includes a winding shaft 37, on which two winding wheels 32 are mounted. These two winding wheels 32 press onto two lower wires respectively. The winding wheels 32 are nested within a second inner ring extended bearing 33. The winding shaft 37 has several evenly spaced mounting holes. The second inner ring extended bearing 33 can be fixed to the winding shaft 37 as needed through these mounting holes. The winding wheels 32 are mounted on the second inner ring extended bearing 33 via a second hub 39, allowing adjustment of the distance between the two winding wheels 32. Both ends of the winding shaft 37 are fixed to the profile frame 35 via winding shaft supports 31. The winding shaft supports 31 are fixed to the profile frame 35 with screws, and the winding shaft 37 and the winding shaft supports 31 are detachably connected via pins. The winding spool support 31 is provided with several mounting holes to allow for vertical adjustment of the winding spool 37 as needed. Thus, the winding wheel 32 can be freely adjusted in four directions (up, down, left, and right), enabling it to function as a winding wheel for four-split conductors.

[0028] Combination Figure 4 and Figure 5The obstacle-crossing mechanism includes two auxiliary arm connectors 20 fixed to the side of the profile frame 35. Each auxiliary arm connector 20 is bolted to a rotatable auxiliary arm rotating support 19. Two auxiliary arms 38 are rotatably connected to the two auxiliary arm rotating supports 19 via auxiliary arm profile bases 18 at their respective bottoms. The two auxiliary arm rotating supports 19 are connected by an HFSF6 profile 23. The HFSF6 profile 23 is equipped with a first opening / closing hydraulic cylinder 21 and a second opening / closing hydraulic cylinder 26. The cylinder barrel end of the first opening / closing hydraulic cylinder 21 is hinged to a second hydraulic cylinder base 22 on the HFSF6 profile 23, and the rod end of the first opening / closing hydraulic cylinder 21 is hinged to a first hydraulic cylinder base 17 on the auxiliary arm 38. The second opening / closing hydraulic cylinder 26 is connected between the HFSF6 profile 23 and the other auxiliary arm 38 in the same manner. A first inner ring extended bearing 12 is provided on the auxiliary arm shaft 11 at the end of each of the two auxiliary arms 38. The first inner ring extended bearing 12 is sleeved on the auxiliary arm shaft 11 and fixed by a pin. The outer ring of the first inner ring extended bearing 12 is nested in a hexagonal hub, and an auxiliary wheel 13 is installed on the outside of the hexagonal hub. A first auxiliary protection wheel 14 is installed at the end of one auxiliary arm shaft 11, and a second auxiliary protection wheel 15 is installed at the end of the other auxiliary arm shaft 11. The first and second auxiliary protection wheels can be interlocked to provide a clamping and protective function. The front and rear sides of the profile frame 35 are also provided with swing hydraulic cylinders 28 for driving the two auxiliary arms 38 to swing left and right. The two auxiliary arms 38 are opened and closed by the extension and retraction of the first opening and closing hydraulic cylinder 21 and the second opening and closing hydraulic cylinder 26, respectively. They can also be swung forward and retracted at a certain angle by the swing hydraulic cylinders 28. Thus, the obstacle-crossing mechanism realizes the obstacle-crossing function through opening and closing, forward swinging and retraction.

[0029] In addition, the profile frame 35 is equipped with two hydraulic stations 24, symmetrically arranged on both sides of the base plate 36, and connected to the corresponding hydraulic cylinders via oil pipes to provide hydraulic power. Figure 1 The first hydraulic oil pipe 25 and the second hydraulic oil pipe 27 shown in the figure are connected to the hydraulic station 24 on the right, the opening and closing hydraulic cylinder and the swing hydraulic cylinder.

[0030] The profile frame 35 has hooks 30 on the front and rear sides, arranged symmetrically, for hanging spacer bars 29.

[0031] Several lifting rings 16 are welded and fixed around the frame 35 for attaching protective ropes.

[0032] The method of using the spacer installation auxiliary operation platform provided in this application embodiment is as follows:

[0033] When the auxiliary working platform encounters an obstacle, the auxiliary obstacle-crossing mechanism can swing and unfold under the drive of the hydraulic station, thereby enabling it to cross the obstacle. After crossing the obstacle, the auxiliary obstacle-crossing mechanism closes again, thereby enabling the engagement of the first auxiliary protective wheel 14 and the second auxiliary protective wheel 15, with the auxiliary wheel 13 resting on the upper guide wire. The operator opens the locking buckle 10 on the traveling mechanism near the obstacle, rotates the entire traveling mechanism along the motor cover support 34, removes the screw at one end of the wire-straightening shaft 37, and the wire-straightening mechanism rotates and hangs down along the other end connecting screw, allowing another set of traveling mechanisms to move forward, thus enabling one set of traveling mechanisms near the obstacle to cross the obstacle. Similarly, another set of traveling mechanisms, the wire-straightening mechanism, and the auxiliary obstacle-crossing mechanism can cross obstacles.

[0034] When installing spacer 29, first use the traveling mechanism and the wire straightening mechanism to adjust the spacing between the four-split conductors, and then remove spacer 29 from the profile frame 35 for installation.
