Embodiment Construction

[0025] Such as figure 1 and figure 2 The overhead cable-laying tractor shown includes a car body, a traction wheel 11 driven by a motor 5, and a traction rope release device. The motor 5 is a geared motor, and the rope groove section of the traction wheel 11 is trapezoidal. Its material is rubber or flexible polyurethane, which is processed by casting or encapsulating. Under the action of gravity, the traction sheave 11 is bonded with the load-bearing steel rope or wire 29 to form an uneven and rough contact surface. Such a flexible and rough contact surface The surface not only improves the friction coefficient of the system, but also can more effectively reduce the wear and tear of the traction sheave 11 on the load-bearing steel rope or the wire 29; The bottom is the battery box 4 as the counterweight; the hook is connected by a vertical hook point bar 10, a hook handle bar 13 and two ends connected by bolts to the hook point bar 10, the hook handle bar 13 top and two upp...

Abstract

The invention discloses an overhead cable laying tractor which comprises a tractor body, traction sheaves driven by a motor and a hauling cable release device. Hooks with downward hook openings are arranged on the upper portion of the tractor body, a balance weight portion is arranged on the lower portion of the tractor body, the lower ends of hook handles of the hooks are connected with the balance weight portion, and the traction sheaves are horizontally arranged in the hook openings. The motor and the hauling cable release device are powered by a battery, a driving circuit of the motor and the hauling cable release device is connected with a wireless communication module, and the wireless communication module is in communication with a remote control unit. The motor, the hauling cable release device, the battery, the driving circuit of the motor and the hauling cable release device and the wireless communication module are respectively arranged on the tractor body. The invention further discloses a dedicated lifting tool of the overhead cable laying tractor. The primary spanning problem of a tension-free cable laying spanning device is solved through the overhead cable laying tractor in wireless control, the influence of the construction field environment on cable laying construction is greatly overcome, the difficulty and cost of the cable laying construction are greatly lowered, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction equipment for electric power and communication lines, in particular to an overhead cable laying tractor and a special lifting tool thereof. Background technique [0002] In the process of power line construction and communication optical cable construction, it is often necessary to cross obstacles such as important waterways, railways, closed highways, houses, vegetable greenhouses, and crossing construction sites. Work, related coordination procedures are numerous, negotiation is difficult, and the construction period is often seriously delayed due to the difficulty in reaching an agreement, and the production cost has remained high for a long time. [0003] However, the traditional cable laying construction mostly uses scaffolding to achieve the purpose of cable spanning through the construction with tension deployment, which has the problems of high cost and long time consumption. Some construction ...
