Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for power transmission tension stringing construction, specifically to a lower fork-type unmanned aerial vehicle (UAV) stringing pulley and pulley block. Background Technology

[0002] Drone-based wire laying pulleys are mainly used in the construction of ultra-high voltage transmission lines, especially suitable for tension wire laying operations. Traditional wire laying methods suffer from problems such as low efficiency, high risk, and high cost. For example, manual wire laying is labor-intensive and inefficient; helicopter wire laying is costly and subject to weather conditions. Drone-based wire laying pulleys can effectively solve these problems and represent a major innovation in transmission line construction technology.

[0003] Existing drone-driven line-laying pulleys still face some problems and challenges in practical applications. For example, traditional drone-driven line-laying pulleys all involve the drone pulling the rope from top to bottom, which is suitable for use with a single pulley. However, in special environments, it is necessary to connect several pulleys in parallel for operation. When traditional drone-driven line-laying pulleys are connected in parallel, there is a problem that the drone cannot pass the rope through the middle pulley. For example, Chinese utility model patent with patent publication number CN 218216365 U discloses an automatic line-crossing pulley. Therefore, when several pulleys are connected in parallel for operation, the drone's pulling rope must also be able to pass through the middle pulley. Utility Model Content

[0004] The purpose of this invention is to provide a lower-fork-type drone line-laying trolley to address the above problems, thereby solving the issue that the drone's traction rope cannot pass through the middle trolley when several trolleys need to be suspended in parallel.

[0005] To achieve the above objectives, this utility model discloses a bottom-fork-type unmanned aerial vehicle (UAV) line-laying trolley, comprising a main trolley frame, an outer guide plate, an inner guide plate, and pulleys.

[0006] The upper end of the main trolley frame is connected to the top of the outer guide plate. The inner guide plate is located between the main trolley frame and the outer guide plate, and a pulley is rotatably connected between the inner guide plate and the main trolley frame. The outer guide plate and the inner guide plate form a channel for guiding the climbing rope. The channel is divided into a lower channel, a middle channel, and an upper channel. The middle channel is an arc-shaped channel. A one-way valve is hinged to the top of the inner guide plate. A one-way valve guide plate is provided on one side of the upper end of the outer guide plate. One side of the one-way valve guide plate is an arc structure. The length of the one-way valve is greater than or equal to the width of the upper channel, and the length of the one-way valve is less than the radius of the arc structure of the one-way valve guide plate.

[0007] The design allows the rope to enter the pulley from bottom to top, and the middle section is designed as an arc-shaped channel to solve the problem that the drone traction rope cannot pass through the middle pulley when multiple drone pulleys are used in parallel. A one-way valve is hinged at the top of the inner guide plate. The cooperation between the one-way valve and the one-way valve guide plate ensures that the one-way valve can only open in one direction, ensuring that the rope will not detach from the one-way valve after falling onto the pulley.

[0008] Preferably, the outer guide plate includes an outer guide plate A and an outer guide plate B, which are connected by an arc transition. The inner guide plate includes an inner guide plate A and an inner guide plate B, which are connected by an arc transition. The arc transition portion of the outer guide plate and the arc transition portion of the inner guide plate form an arc-shaped channel.

[0009] Preferably, the outer guide plate includes an outer guide plate C, the inner guide plate includes an inner guide plate C, and the outer guide plate C and the inner guide plate C form a "figure-eight" shaped opening channel.

[0010] Preferably, a spring-loaded hinge is provided between the inner guide plate and the one-way valve.

[0011] Preferably, the top of the inner guide plate is provided with a hinge plate A, the end of the one-way valve is provided with a hinge plate B, a pivot is provided at the connection between the hinge plate A and the hinge plate B, and a torsion spring is sleeved on the pivot.

[0012] Preferably, the one-way valve guide plate and the outer guide plate are integrally formed.

[0013] Preferably, there is one or more pulleys.

[0014] Preferably, the pulley is rotatably mounted between the inner guide plate and the main frame of the trolley via an axle, and the pulley is provided with a groove for traction rope.

[0015] Preferably, the top of the trolley main frame is provided with a suspension hole.

[0016] A bottom-entry type unmanned aerial vehicle (UAV) line-laying trolley assembly includes a connecting plate and multiple UAV line-laying trolleys, which are connected by the connecting plate.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a bottom-fork-type drone line-laying trolley, which allows the drone's traction rope to enter the pulley from bottom to top, thus solving the problem that the drone's traction rope cannot pass through the middle pulley when several pulleys need to be suspended in parallel.

[0018] This invention provides a stable guiding path for the rope by setting inner and outer guide plates, ensuring that the rope can accurately enter the pulley groove, effectively preventing deviation and rope jamming, and ensuring smooth operation. The one-way valve design allows the rope to pass smoothly through the pulley under the traction of the drone, and ensures that the rope will not fall off the pulley after passing through the one-way valve, without manual intervention, improving work efficiency and safety, reducing labor costs and operational risks, and is especially suitable for power transmission line construction scenarios with multiple pulley carts suspended in parallel in complex environments.
