Description

Technical Field

[0001] This utility model belongs to the technical field of aerial cableway equipment, specifically relating to a double-bearing single-traction reciprocating cableway maintenance vehicle. Background Technology

[0002] Currently, maintenance of double-bearing, single-traction reciprocating cableways is divided into two operation methods, depending on the type of suspender. The first method is for single-spear suspender cableways, where maintenance personnel climb a ladder on the suspender to reach a work platform at the top. However, this method is limited by the suspender's cross-sectional dimensions, resulting in a narrow work platform that can only accommodate 1-2 people, and personnel must carry the necessary parts and tools. The second method is for double-spear suspender cableways, where maintenance personnel stand on the horizontal support connecting the two support poles to complete the maintenance. However, the standing area on the horizontal support is small in this method, and personnel must also carry the necessary parts and tools. Therefore, both of these operation methods bring significant inconvenience and safety risks to maintenance work, reducing maintenance efficiency. Utility Model Content

[0004] This utility model proposes a double-load-bearing, single-traction reciprocating cableway maintenance vehicle to solve the technical problem of how to conveniently and quickly replace or relocate the support cable while ensuring the safety of personnel.

[0005] (II) Technical Solution

[0006] To address the aforementioned technical problems, this utility model proposes a double-load-bearing, single-traction reciprocating cableway maintenance vehicle. This vehicle includes a top drive mechanism, a traction cable clamping device, a central connecting pipe, a support ladder, a folding ladder, a hand-operated hoist, a winch, a support cable assembly / disassembly bracket, and a work platform.

[0007] The central connecting pipe runs through the top drive mechanism and serves as its support shaft. The left and right ends of the central connecting pipe are connected to the tops of two supporting ladders, respectively. The traction cable clamping device is connected to two ear plates below the top drive mechanism. A winch is connected to one of the supporting ladders. A steel wire rope extending from the winch passes over a pulley below the top drive mechanism, suspending the support cable assembly / disassembly bracket below the top drive mechanism. The winch is used to raise or lower the support cable assembly / disassembly bracket. The bottoms of the two supporting ladders are connected to both sides of the work platform. A folding ladder is connected to a lifting ring on the work platform via a tension strap. A hand-operated hoist is attached to the top hanger of the top drive mechanism to pull the traction cable to the clamping position of the traction cable clamping device before the clamping device clamps it.

[0008] Furthermore, the top drive mechanism includes a main beam, rollers, and top hangers; four rollers are respectively installed on the front and rear sides of the main beam; two top hangers are fixed to the top of the main beam for attaching a hand chain hoist.

[0009] Furthermore, two ice-breaking devices are fixed at the front and rear ends of the main beam, respectively.

[0010] Furthermore, each roller is equipped with a snow scraper on the side closest to the central connecting tube.

[0025] This embodiment proposes a dual-load, single-traction reciprocating cableway maintenance vehicle, the overall structure of which is as follows: Figure 1 As shown, it mainly includes a top drive mechanism 1, a traction cable clamping device 2, a central connecting pipe 3, a support ladder 4, a folding step ladder 5, a 1.6t hand chain hoist 6, a manual winch 7, a support cable disassembly and assembly bracket 8, a work platform 9, a guardrail 10, a toolbox 11, and a folding seat 12.

[0026] The central connecting pipe 3 passes through the top drive mechanism 1 and serves as its support shaft. The left and right ends of the central connecting pipe 3 are connected to the tops of the two supporting ladders 4, respectively. The traction cable clamping device 2 is connected to two ear plates below the top drive mechanism 1 via pins 2-3 and expansion sleeves 2-4. The manual winch 7 is bolted to one of the supporting ladders 4. A steel wire rope extending from the manual winch 7 passes over a pulley below the top drive mechanism 1, suspending the support cable disassembly bracket 8 below the top drive mechanism 1.

The guardrail 10 is bolted to the work platform 9, and the toolbox 11 and folding seat 12 are bolted to the guardrail 10. The folding ladder 5 is connected to the lifting ring on the work platform 9 via a tension strap, and the 1.6t hand-operated hoist 6 is attached to the top hanger of the top drive mechanism 1.

[0027] like Figure 2aAs shown, the top drive mechanism 1 mainly includes a main beam 1-1, ice-breaking devices 1-2, rollers 1-3, snow scrapers 1-4, anti-derailment baffles 1-5, and top hangers 1-6. Two ice-breaking devices 1-2 are bolted to the front and rear ends of the main beam 1-1, respectively. Four rollers 1-3 are installed on the front and rear sides of the main beam 1-1, respectively. A snow scraper 1-4 is bolted to the side of each roller 1-3 closest to the central connecting pipe 3, and anti-derailment baffles 1-5 are bolted to both sides of each roller 1-3 to prevent the wire rope from slipping and ensure the safe movement of the maintenance vehicle.
