Technical Field

[0001] This invention relates to a mobile telescopic automatic netting crossing equipment for power transmission lines and its working method, belonging to the technical field of power line construction equipment. Background Technology

[0002] With the rapid development of the power industry, the construction and renovation of power transmission lines are increasing. During the construction of power transmission lines, it is often necessary to cross existing lines, highways, railways and other obstacles. Traditional methods of crossing these obstacles often rely on the manual construction of temporary facilities, which has problems such as low construction efficiency, poor safety and great impact on the surrounding environment and traffic. These methods can no longer meet the needs of modern power transmission line projects for efficient, safe and green construction.

[0003] Currently, in the construction of cross-road bridges and elevated railways, safety protection work is mostly carried out by setting up isolation nets and erecting scaffolding. These safety protection methods pose a great threat and hidden danger to traffic safety and also have a significant impact on traffic organization.

[0004] In the prior art, Chinese patent document CN121172635A discloses a lifting crossing frame for power transmission line construction. The crossing frame includes a base, the upper end of which contacts the crossing frame body. Fixed plates are fixedly connected to both ends of the base. A support seat is fixedly connected to the horizontal part of the crossing frame body. A movable lifting mechanism is jointly provided on the fixed plates, the crossing frame body, and the base. A winding mechanism is jointly provided on the crossing frame body and the support seat. This crossing frame is essentially a support frame and cannot achieve completely independent crossing and closure operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mobile telescopic automatic netting crossing equipment for power transmission lines and its operating method. It achieves high-strength protection and electromechanical integration, eliminating threats and hidden dangers to traffic safety during crossing operations. It significantly reduces the impact on traffic organization, improves the efficiency of safety protection engineering for crossing operations, and achieves the goals of equipment safety, reliability, efficiency, mechanization, automation, and intelligence. It is also adaptable to safety protection operations under different environmental conditions.

[0006] The technical solution of the present invention is as follows:

[0007] A mobile telescopic automatic netting crossing equipment for power transmission lines includes a vehicle body, a main telescopic arm and a crossbeam assembly. The main telescopic arm is hinged to the vehicle body via a turntable. A main rotating hydraulic cylinder is provided between the main telescopic arm and the turntable. A crossbeam assembly is hinged to the top of the main telescopic arm. A supporting hydraulic cylinder is provided between the main telescopic arm and the crossbeam assembly.

[0008] The crossbeam assembly includes several crossbeam supports, which are nested together by a drive assembly, and a sealing mesh assembly is installed inside the crossbeam supports.

[0009] According to a preferred embodiment of the present invention, hydraulic support legs are respectively provided at the four corners of the vehicle body. During operation, the hydraulic support legs are deployed to ensure the overall stability of the vehicle body.

[0010] According to a preferred embodiment of the present invention, each crossbeam support is symmetrically provided with a sealing net assembly.

[0011] According to a further preferred embodiment of the present invention, the sealing net assembly includes a first curved arm, a second curved arm, a straight arm, an adjusting cylinder, and a sealing net roller. The first curved arm is hinged to both ends of one side of the crossbeam support, the first curved arm is hinged to the second curved arm, a straight arm is provided between the two second curved arms, an adjusting cylinder is provided between the first curved arm and the crossbeam support, and a sealing net roller is also provided on the crossbeam support. One end of the sealing net inside the sealing net roller is connected to the straight arm, and when the straight arm moves outward, it drives the sealing net to extend outward.

[0012] According to a preferred embodiment of the present invention, the sealing roller, the straight arm, and the crossbeam support are parallel.

[0013] According to a preferred embodiment of the present invention, the drive assembly includes a gear and a drive motor. The top of the beam support nested inside is symmetrically provided with teeth, and the drive motor is symmetrically provided inside the beam support corresponding to the teeth. The output shaft of the drive motor is connected to the gear, and the gear meshes with the teeth. The drive motor drives the gear to rotate, thereby driving the beam support to extend and retract.

[0014] According to a preferred embodiment of the present invention, an auxiliary telescopic arm is hinged to the end of the outermost crossbeam support after extension, and an auxiliary rotating cylinder is provided between the crossbeam support and the auxiliary telescopic arm.

[0015] The working method of the above-mentioned mobile telescopic automatic barrier crossing equipment for power transmission lines is as follows:

[0016] S1, the crossing equipment enters the work site, reaches the preset coordinate position and adjusts the vehicle body orientation. The hydraulic support legs are deployed to support the vehicle body, so that the crossing equipment is stably parked in the work position.

[0017] S2, the turntable rotates to bring the main telescopic arm to the preset position, then the main rotary cylinder extends to make the main telescopic arm vertical, and then the main telescopic arm extends to bring the crossbeam assembly to the set height;

[0018] S3 supports the extension of the hydraulic cylinder, bringing the crossbeam assembly to a horizontal position. Then, the drive motor rotates, and through the transmission of gears and meshing teeth, it drives the crossbeam support nested inside to extend outward.

[0019] S4. After all the crossbeam supports have been extended into place, the netting assembly is deployed. At the same time, the auxiliary rotating cylinder extends, adjusting the auxiliary telescopic arm to a vertical position. The auxiliary telescopic arm extends to the ground, providing overall stability support for the crossing equipment. Thus, the crossing of the road below is completed.

[0020] According to a preferred embodiment of the present invention, in step S4, the unfolding process of the sealing net assembly is as follows: the hydraulic cylinder is adjusted to extend, causing the first curved arm to extend outward. At the same time, under the limiting action, the second curved arm extends along with the first curved arm. During the movement, the straight arm causes the sealing net to extend outward until it is fully unfolded.

[0021] According to a preferred embodiment of the present invention, in step S4, if an ultra-wide crossing scenario is encountered, i.e., one crossing device cannot cross the road, two crossing devices are used in conjunction to achieve a wider range of protective coverage.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention achieves fully automated operation of positioning, deployment, docking, net sealing, and recovery through the efficient collaboration of various components.

[0024] 2. This invention can be used for single or multiple vehicle combinations according to construction needs, flexibly adjusting the protection width and crossing distance to adapt to new lines of various voltage levels and various types of road crossing construction, meeting a variety of construction needs from rural roads to high-speed railways, and achieving efficient and safe crossing construction.

[0025] 3. From deployment to full arm deployment, this invention can complete the automatic netting operation of the entire vehicle within 30 minutes. The entire operation process is mechanized, and the remote control is reliable and precise. Attached Figure Description

[0033] Example 1:

[0034] like Figure 1-5 As shown, this embodiment provides a mobile telescopic automatic netting crossing equipment for power transmission lines, including a vehicle body 1, a main telescopic arm 3 and a crossbeam assembly 18. The main telescopic arm 3 is hinged to the vehicle body 1 via a turntable. A main rotating cylinder 2 is provided between the main telescopic arm 3 and the turntable 17. The crossbeam assembly 18 is hinged to the top of the main telescopic arm 3. A supporting hydraulic cylinder 4 is provided between the main telescopic arm 3 and the crossbeam assembly 18.

[0035] The crossbeam assembly 18 includes a first crossbeam support 13, a second crossbeam support 14, and a third crossbeam support 15. The first crossbeam support 13, the second crossbeam support 14, and the third crossbeam support 15 are nested together by a drive assembly. Each of the first crossbeam support 13, the second crossbeam support 14, and the third crossbeam support 15 is symmetrically equipped with a sealing net assembly.

[0036] Hydraulic support legs 7 are installed at the four corners of the vehicle body 1. When in operation, the hydraulic support legs are deployed to ensure the overall stability of the vehicle body.

[0037] The sealing net assembly includes a first curved arm 8, a second curved arm 9, a straight arm 10, an adjusting cylinder 11, and a sealing net roller (the sealing net roller is an existing device, not shown in the figure, and is a conventional drum design, driven and controlled by a motor on the outside). The first curved arm 8 is hinged to both ends of one side of the crossbeam support, and the first curved arm 8 is hinged to the second curved arm 9. A straight arm 10 is arranged between the two second curved arms 9. An adjusting cylinder 11 is arranged between the first curved arm 8 and the crossbeam support. The sealing net roller is also arranged on the crossbeam support. One end of the sealing net 12 inside the sealing net roller is connected to the straight arm 10. When the straight arm moves outward, it drives the sealing net to extend outward.

[0038] The sealing roller, straight arm 10, and crossbeam support are parallel.

[0039] The drive assembly includes gear 16 and a drive motor. The tops of the second crossbeam support 14 and the third crossbeam support 15 are symmetrically equipped with meshing teeth. Corresponding to the meshing teeth, drive motors are symmetrically arranged inside the first crossbeam support 13 and the second crossbeam support 14. The output shaft of the drive motor is connected to a gear, and the gear meshes with the meshing teeth. The drive motor drives the gear to rotate, thereby causing the crossbeam supports to extend and retract. To facilitate the sliding of the first crossbeam support 13, the second crossbeam support 14, and the third crossbeam support 15, sliding components such as slide rails and grooves are designed inside. This is a conventional design and will not be described in detail.

[0040] An auxiliary telescopic arm 6 is hinged to the end of the third crossbeam support 15, and an auxiliary rotating cylinder 5 is provided between the third crossbeam support 15 and the auxiliary telescopic arm 6.

[0041] The working method of the above-mentioned mobile telescopic automatic barrier crossing equipment for power transmission lines is as follows:

[0042] S1, the crossing equipment enters the work site, reaches the preset coordinate position and adjusts the vehicle body orientation. The hydraulic support leg 7 unfolds to support the vehicle body 1, so that the crossing equipment is stably parked in the work position.

[0043] S2, the turntable 17 rotates, so that the main telescopic arm 3 reaches the preset position. Then, the main rotary cylinder 2 extends, so that the main telescopic arm 3 is vertical. Then the main telescopic arm 3 extends, so that the crossbeam assembly 18 reaches the set height.

[0044] S3, support the extension of hydraulic cylinder 4 to bring the crossbeam assembly 18 to a horizontal state, and then drive the motor to rotate. Under the transmission cooperation of gear 16 and meshing teeth, the second crossbeam support 14 and the third crossbeam support 15 nested inside will extend outward.

[0045] S4. After all the crossbeam supports have been extended into place, the netting assembly is deployed. At the same time, the auxiliary rotating cylinder 5 extends, adjusting the auxiliary telescopic arm 6 to a vertical position. The auxiliary telescopic arm 6 extends to the ground, providing overall stability support for the crossing equipment. Thus, the crossing of the road below is completed.

[0046] The process of unfolding the sealing net assembly is as follows: the hydraulic cylinder 11 is extended, which drives the first curved arm 8 to extend outward. At the same time, under the action of the limit, the second curved arm 9 extends along with the first curved arm 8. During the movement, the straight arm 10 drives the sealing net 12 to extend outward until it is fully unfolded.

[0047] In the case of ultra-wide crossing scenarios, where one crossing device cannot cross the road, two crossing devices can be used together to achieve a wider range of protective coverage.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are intended to limit the present invention.
