Description

Technical Field

[0001] The invention relates to the technical field of spanning frames, in particular to a spanning frame device for a power transmission line. Background Art

[0002] When erecting transmission lines, it is often necessary to cross roads and railways, which brings great inconvenience to the work of erecting transmission lines. At present, the method of erecting transmission lines across roads is: manually erecting brackets on both sides of the road or railway, and then workers stand on the top of the two brackets and lay a protective net between the two brackets, so that the transmission line is finally placed on or above the protective net between the two brackets;

[0003] Since the transmission line crossing frame needs to be disassembled and moved to the next place where the transmission line needs to be supported after being tightened at both ends of the transmission line, the existing method of erecting the support needs to be disassembled and re-erected at the next place each time a place is switched, which is time-consuming and labor-intensive, and the installation cycle is long. In addition, it is very inconvenient for workers to stand on the top of the two supports to install the protective net between the two supports, and high-altitude operations are required, which has high work risks.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0005] The purpose of the present invention is to provide a transmission line crossing frame device to solve the problem proposed in the above-mentioned background technology that each time a place is switched, it needs to be disassembled and re-erected in the next place, which is time-consuming and labor-intensive, and the installation period is long. It is very inconvenient for workers to install the protective net between the tops of the two brackets, and high-altitude operations are required, which has high work risks.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A transmission line spanning frame device, comprising:

[0008] A wiring unit, comprising a protective net arranged under the transmission line components for protecting the transmission line components;

[0009] A lifting unit is provided at the lower end of the wiring unit and located on both sides of the road, and is used to lift and lower the wiring unit;

[0010] The supporting unit is installed on the ground and is used to position the bottom of the lifting unit.

[0011] Furthermore, the support unit comprises:

[0012] The chassis is provided with two groups, which are respectively located on both sides of the road, and the lower end of the chassis is provided with a driving wheel for driving the chassis forward;

[0013] Fixed sleeves, fixedly connected to both sides of the chassis, with two sets installed each time;

[0014] A rotatable support arm, one end of which is hinged inside the fixing sleeve and is used to increase the bottom support area of ​​the chassis, and a through hole is provided at one end of the rotatable support arm opposite to the fixing sleeve;

[0015] The fastening nails are inserted into the through holes and are used to be pushed into the ground to position the chassis.

[0016] Furthermore, the lifting unit comprises:

[0017] There are two sets of scissor lifts, which are respectively mounted on the upper ends of the two sets of chassis;

[0018] The cylinder is installed inside the scissor lift frame and is used to drive the scissor lift frame to move up and down.

[0019] Furthermore, the wiring unit also includes:

[0020] The first support platform and the second support platform are respectively and correspondingly mounted on the upper ends of the two groups of scissor lifts;

[0021] A hanging shaft is arranged on a side of the first support platform close to the second support platform. The hanging shaft is fixedly connected to the first support platform through a base and is used to limit one end of the protective net extending from the second support platform.

[0022] Furthermore, a fixing block is fixedly connected to one side of the second support platform, and the fixing block is provided in two groups;

[0023] The two groups of fixed blocks are internally rotatably connected with rollers;

[0024] A driving motor for rotating and adjusting the roller is provided at one end of the roller, and the driving motor is installed on one side of the fixing block.

[0025] Furthermore, the protective net is wound on the outside of the winding roller and the initial end of the protective net is fixedly connected to a hook for hanging on the outside of the hanging shaft.

[0026] Furthermore, the upper ends of the first support platform and the second support platform are respectively fixedly connected with a first limit block and a second limit block at equal intervals, which are used to limit the power transmission line components placed on the protective net after falling or breaking.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention moves two sets of chassis with driving wheels to the two sides close to the road respectively, rotates the rotating support arm around the fixing sleeve to a position perpendicular to the side of the chassis, and then inserts a fastening nail into each through hole respectively, and then hammers the fastening nail downward into the ground, so that the chassis can be positioned while increasing the bottom support area, ensuring that the chassis will not topple over due to the gradual increase of the center of gravity during the subsequent upward extension of the support unit, thereby improving the overall stability of the cross-domain frame.

[0029] 2. The present invention starts the corresponding cylinders in the two groups of scissor-type lifting frames synchronously, and the cylinders drive the scissor-type lifting frames to expand upward. The scissor-type lifting frames synchronously drive the first support platform and the second support platform to move upward, and the second support platform drives the winding roller to move upward through the fixed block until the first support platform and the second support platform rise to a height between the working line and the transmission line components and stop moving upward. At this time, the drive motor is remotely started, and the drive motor drives the winding roller to unwind the protective net. The clamping block is clamped by controlling the drone with claws and drives the clamping block to move toward the hanging axis. The clamping block drives the protective net to be laid between the working line and the transmission line components through the hook until the hook is brought to the hanging axis, and the hook is released. The hook is hung on the upper part of the hanging axis under the action of gravity, and the drive motor is controlled to stop rotating, thereby completing the laying of the protective net, thereby eliminating the need to manually lay and install the protective net at a high place, and the installation is convenient and the work risk is small.

[0030] 3. The present invention uses a drone to bring the hook out from the upper part of the hanging shaft, and then drives the roller to wind the protective net through a driving motor, drives the scissor-type lifting frame to retract downward by controlling the cylinder, and the scissor-type lifting frame drives the first support platform and the second support platform to descend to the initial position, and finally pulls out the fastening nails and folds the rotating support arm. The disassembly and assembly process is simple and fast, and the installation period is short. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In addition, the protection net 34 is wound on the outside of the winding roller 361 and the initial end of the protection net 34 is fixedly connected with a hook 33 for hanging on the outside of the hanging shaft 32;

[0058] Preferably, a clamping block 331 is provided at the upper end of the hook 33 to facilitate the drone to clamp the hook 33 .

[0060] It should be added that during the construction of the transmission line component 103 in the present invention, there is a working line 102 below. The present invention lays a protective net 34 below the transmission line component 103 during the construction of the transmission line component 103 to prevent the transmission line component 103 from falling or breaking and falling onto the working line 102 during the construction of the transmission line component 103, thereby preventing safety hazards.

[0061] It should be noted that: in the specific implementation process of the present invention, initially, the rotating support arm 24 is folded on one side of the chassis 21, the scissor lift frame 11 is in a tightened state, and the protective net 34 is completely wound on the outside of the roller 361;

[0062] like Figure 1 , Figure 5-6 As shown, when it is necessary to protect the transmission line 103 above the working line 102, the two sets of chassis 21 with driving wheels 22 are respectively moved to the two sides close to the road 101, and the rotating support arm 24 is rotated around the fixing sleeve 23 to a position perpendicular to the side of the chassis 21, and then the fastening nail 25 is inserted into each through hole 241, and then the fastening nail 25 is hammered downward into the ground 100, so that the chassis 21 can increase the bottom support area while positioning the chassis 21, ensuring that in the subsequent upward extension process of the support unit 2, it will not fall due to the gradual increase of the center of gravity, thereby improving the overall stability of the cross-domain frame;

[0063] like Figure 2-4 As shown, then, the corresponding cylinders 12 in the two sets of scissor-type lifting frames 11 are synchronously started, and the cylinders 12 drive the scissor-type lifting frames 11 to expand upward, and the scissor-type lifting frames 11 synchronously drive the first support platform 31 and the second support platform 35 to move upward, and the second support platform 35 drives the roller 361 to move upward through the fixed block 36, until the first support platform 31 and the second support platform 35 rise to a height between the working line 102 and the transmission line 103 and stop moving upward, at this time, the drive motor 362 is remotely started, and the drive motor 362 drives the roller 361 to move the protective net 34 Unwinding: Control the drone with the clamp to clamp the clamp block 331 and drive the clamp block 331 to move toward the hanging shaft 32. The clamp block 331 drives the protective net 34 to be laid between the working line 102 and the transmission line device 103 through the hook 33 until the hook 33 is brought to the hanging shaft 32. Release the hook 33. The hook 33 is hung on the upper part of the hanging shaft 32 under the action of gravity.
