Description

A self-obstacle-surmounting ground wire flying car for maintenance

technical field

The invention relates to a ground flying car, in particular to an autonomous obstacle-crossing type ground flying car for maintenance.

Background technique

Large spans with a height of more than 100 meters are high-rise structures. Large spans in power transmission lines are mainly subjected to wind loads, earthquake loads and installation loads, among which wind loads are the most dominant. Large spans are generally located on the coasts of rivers, lakes, rivers and seas, and the wind environment is harsh, so the dynamic response under the action of wind load is particularly strong. Therefore, large spans often adopt a combination of damping wire clamps and shockproof hammers. Due to the importance and particularity of large spans, eliminating the defects of large spans often requires high standards and high efficiency. However, due to the large span and towering heights, high-altitude operations, especially ground wire and optical cable operations, have put forward higher requirements on the psychological endurance and labor intensity of the operators, which has caused certain difficulties in the work of eliminating defects.

For the defect of ground wire, the common way of eliminating the defect is usually adopted. Common flying car is made up of front and back two pulleys and support frame. The operator sits sideways or rides on the support frame, relying on the front and rear pulleys to realize the wire exit. But ordinary flying cars do not have the ability to overcome obstacles. For large-span towers, the current way of eliminating defects is to use the foot hook outlet method. During operation, the outlet foot hooks are hung on the ground wire and optical cable, and a nylon rope is tied to the foot rings of the two foot hooks as a balance rope. The rope runs along the top of the tower. The rack walkway is about 20 meters backward and controlled by the coordinating personnel to keep the outgoing personnel in an upright position during the outgoing operation to prevent losing the center of gravity. The outgoing personnel stand on the outgoing line foot hook, put a waist rope on the optical cable (in the middle of the two hooks), first lift the outer foot, move the foot hook forward 0.4~0.6m, move the waist rope, then lift the inner foot, and put the foot The hook moves forward and goes to the operation point to eliminate the gap. Therefore, in the traditional way of eliminating gaps, operators not only have to overcome the difficulties of hanging their bodies in the air and making it difficult to exert force, but also travel slowly, take a long time to get out of the line, consume a lot of physical strength, and work efficiency is low, and the psychological pressure of personnel is huge.

detailed description

In order for examiners to better understand the technical features, technical contents and technical effects of the present invention, the accompanying drawings of the present invention will now be described in more detail in conjunction with the embodiments. However, the drawings shown are only for better illustration of the technical solutions of the present invention, not the true scale and optimal configuration of the present invention, so the examiner is requested not to limit the scope of the present invention with respect to the ratio and configuration of the drawings Scope of claims.

Below in conjunction with accompanying drawing and embodiment the patent of the present invention is further described.

As shown in Figures 1-3, the present invention provides an autonomous obstacle-crossing ground wire flying vehicle for maintenance, which includes two wheel frames 3 and a cage seat frame 10, and the edges on both sides of the lower end of the two wheel frames 3 pass through Connecting rod 8 is fixed together, and axle 2 is installed on each described wheel frame 3, and main pulley 1 is installed on described axle 2, and the intermediate position of described connecting rod 8 is provided with from pulley 4, and described from pulley 4 Connect with the connecting rod 8 through the hinge 6, handles 5 are provided at both ends of the slave pulley shaft 7, and the lower ends of the same side of the two wheel frames 3 are connected to the upper end of the cage seat 10 through the anti-off device 9 The other side is fixedly connected with the upper end of the cage seat 10, the lower end of the cage seat 10 is provided with a backing plate 12, and the handle 5 is U-shaped. By setting the slave pulley between the two main pulleys and using the principle of leverage, the purpose of autonomously overcoming obstacles such as damping clamps and anti-vibration hammers is realized; in addition, the seat frame of the operator in the present invention adopts a cage structure, and the operator curls up Sitting in it, the balance is guaranteed, and the psychological pressure and labor intensity are effectively reduced; moreover, the present invention uses the tail rope to control the speed of the flying car. Compared with the braking device on the traditional flying car, the total weight of the flying car is reduced. Reduced and improved safety.

The anti-off device 9 is a pin bolt, which not only prevents the pulley from falling off, but also is easy to operate.

When working at heights, the psychological pressure of the workers is often relatively high, and the balance is not easy to control. A fence 11 is set around the cage frame 10, and the workers curl up in the cage frame 10 to work, so the balance is better. On the one hand It can protect the safety of the operators and reduce the psychological pressure of the operators. If it is used for a long time, the fence 11 may be damaged, so the fence 11 is fixedly connected to the cage seat 10 by bolts, and a damaged fence can be directly removed and replaced without replacing the entire cage seat. This greatly reduces the cost of use.

In addition, due to the different heights of the workers, they are curled up in the cage-type seat frame. When working with their heads up, their heads are likely to stick out of the cage-type seat frame, which poses a safety hazard. Protective bar 13 is arranged, and described protective bar 13 is sleeved on the described cage mount 10, and the height of protective bar can be adjusted according to actual needs, and is fixed with bolt.

When the workers are working on the line, the speed of the line is related to the work efficiency. However, relying solely on an operator on the flying car to control the advancing and retreating of the flying car requires too much physical strength for the operator, making it difficult to control the speed of exiting the line, and basically impossible to return. Therefore, a brake device is provided on the cage mount 10, and the brake device is a tail rope brake. Use together, the effect is better. This design reduces the weight of the flying car itself and improves safety.

The present invention has been disclosed above with preferred embodiments, but it is not intended to limit the present invention. All technical solutions obtained by adopting equivalent replacement or equivalent transformation schemes fall within the protection scope of the present invention.
