Abstract
Description
Technical Field
[0001] The invention relates to the technical field of high-voltage transmission line maintenance, and in particular to a wire routing flying car capable of crossing wire obstacles. Background Art
[0002] In the field of ultra-high voltage and ultra-high voltage transmission, in order to suppress corona discharge and reduce line impedance, multiple split conductors are usually used to erect transmission lines. Split conductors are prone to wear, loose strands, even broken strands, loose spacers and other hidden defects due to construction damage and long-term effects of the external environment. In order to ensure the safe and stable operation of overhead transmission lines, operating units must regularly perform maintenance and inspections on the lines under their jurisdiction. The main method is for operators to stand on a split conductor, support two conductors with both hands, walk on foot, and inspect section by section. During the wiring process, operators need to distribute their body weight to the conductors on both sides to maintain balance. If uneven force occurs, it is easy for operators to flip over on the conductors, causing physical injuries. Long-term wiring can easily cause operators to lose physical strength and arch injuries.
[0003] At present, the wiring inspection and maintenance methods applicable to the split conductors of overhead transmission lines can be roughly divided into the following three types: 1) The walking wiring method of operators. This method mainly relies on the walking operation of operators. The operators hold the two upper wires of the split conductor with their hands or simple instruments respectively, and walk on the lower wire of the split conductor with their feet to perform the "straight step" forward movement. The operators have to pay a lot of physical energy. Long-term wiring will cause arch damage, and long-term practice is required to be competent for this wiring work. 2) Large electric wiring device. This electric wiring device mainly relies on large motors as transmission mechanisms. Operators sit in large wiring devices and control the moving speed. The device has a dead weight (more than 80 kilograms) and a large volume, which is extremely inconvenient to use. 3) Mechanical wiring device. This mechanical wiring device is composed of main components such as gears, chains, pulleys, etc. It is used for manual riding. The driving speed is slow, the device volume is slightly larger, and the physical energy consumption of personnel is less than that of walking wiring.
[0004] In the design of wiring maintenance equipment, the ability to cross wire obstacles (such as online spacers, etc.) is a basic requirement. Although there are many similar products on the market, they still cannot solve the technical problem of crossing wire obstacles. Summary of the invention
[0005] The purpose of the present invention is to provide a wiring flying car that can cross wire obstacles, overcome the shortcomings of the prior art, adopt a flying car structure with a variable hanging point, form a leaping mobile walking, and when encountering online obstacles such as spacers, it can easily cross the obstacles without affecting the progress. The structure is simple, the weight is light, and it is easy to carry, which can meet the needs of routine maintenance wiring operations.
[0006] To achieve the above object, the technical solution of the present invention is as follows:
[0007] A wire-walking vehicle that can cross wire obstacles, including a bracket, a cross bar, a seat board and wheel frames. There are three wheel frames, which are respectively arranged at both ends and in the middle of the cross bar. Each wheel frame includes an upper wheel frame and a lower wheel frame. The upper wheel frame has a gate-shaped structure. The upper wheel frame is connected to a pulley through a wheel shaft, and a D-shaped pin is provided at the closed door. The upper wheel frame and the lower wheel frame are connected by bolts, and their relative positions are adjustable. Both ends of the cross bar are connected to the bracket through end joints. There is an intermediate joint in the middle of the cross bar. The tops of the end joints and the intermediate joint are both provided with connecting bodies that match the bottom ends of the lower wheel frames. When in use, the high-altitude line inspection personnel first hang the three pulleys on the overhead wire, then sit on the seat board, and move along the wire by using their hands as power. When encountering a spacer or other obstacles, open the D-shaped pin of the frontmost group of wheel frames, disconnect the upper wheel frame from the overhead wire, and continue to move forward. When the middle group of wheel frames reaches in front of the spacer, hang the frontmost group of wheel frames back on the overhead wire again, then disconnect the middle group of wheel frames from the overhead wire, and continue to move forward. When the last group of wheel frames reaches in front of the spacer, hang the middle group of wheel frames back on the overhead wire again, and then disconnect the last group of wheel frames from the overhead wire.
[0008] Furthermore, the high-altitude line inspection personnel adjust the center of gravity position by slightly moving left and right on the seat board, in cooperation with the operation of hanging and disconnecting the upper wheel frame from the overhead wire.
[0009] Furthermore, the lower wheel frame is replaced by an electric lifting push rod assembly. The piston end of the electric push rod is connected to the upper wheel frame, and the bottom of the electric push rod is connected to the corresponding position of the end joint or the intermediate joint.
[0010] Furthermore, at least one D-shaped pin is provided at the connection between the upper wheel frame and the lower wheel frame.
[0011] Furthermore, an auxiliary bracket for improving the support strength is provided at the bottom of the seat board.
[0012] Furthermore, a bearing is provided between the pulley and the wheel shaft, and a bearing pad for limiting is provided between the outer side of the bearing and the upper wheel frame.
[0013] Furthermore, the intermediate joint can slide left and right along the surface of the cross bar.
[0014] Furthermore, the cross bar is made of steel pipe, and pipe plugs are provided at both ends. The pipe plugs are connected to the ends of the cross bar through threads.
[0015] Furthermore, a non-metallic insert hexagon lock nut for preventing falling off is connected to the tail of the wheel shaft.
[0016] Furthermore, the width of the seat board is 700 - 900 mm.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] 1) A flying vehicle structure with variable suspension points is formed by using three wheel frames. When the flying vehicle moves along the wire, when encountering on-line obstacles such as spacer dampers, it can easily cross the obstacles without affecting the progress, and can meet the requirements of routine maintenance wire walking operations;
[0019] 2) The overall structure of the wire walking vehicle is streamlined, with a light self-weight and is convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to more clearly illustrate the specific embodiments of the present invention or the technical solutions in the prior art, the accompanying drawings required for use in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.
[0030] Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.
[0031] See Figure 1-2 As shown, the structural schematic diagram of the embodiment of the wire-walking vehicle of the present invention that can cross wire obstacles includes a bracket 1, a cross bar 2, a seat plate 3, and wheel frames. There are three wheel frames, which are respectively arranged at both ends and in the middle of the cross bar 2, and include an upper wheel frame 4 and a lower wheel frame 5. The upper wheel frame 4 has a portal structure. The upper wheel frame 4 is connected to a pulley 7 through a wheel shaft 6. A D-shaped pin 8 is provided at the closing door. A bearing 12 is provided between the pulley 7 and the wheel shaft 6. A bearing pad 13 for limiting is provided between the outside of the bearing 12 and the upper wheel frame 4. The tail of the wheel shaft 6 is connected with a non-metallic insert hexagon lock nut to prevent falling off.
[0032] The upper wheel frame 4 and the lower wheel frame 5 are connected by bolts, and their relative positions can be adjusted; both ends of the cross bar 2 are connected to the bracket 1 through end joints 9. A middle joint 10 is provided at the middle of the cross bar 2. Connection bodies matching the bottom ends of the lower wheel frames 5 are provided at the tops of the end joints 9 and the middle joint 10. The middle joint 10 can slide left and right along the surface of the cross bar 2. The cross bar 2 is made of steel pipe, and pipe plugs 14 are provided at both ends thereof. The pipe plugs 14 are connected to the ends of the cross bar 2 by threads.
[0033] The width of the seat board 3 is 700 - 900 mm, preferably 800 mm, which is convenient for the aerial line inspection operators to sit on, and there is space for left - right movement. The position change of the aerial line inspection operators on the seat board 3 can adjust the center - of - gravity position of the wire - walking vehicle, reducing the force between the frontmost or the rearmost upper wheel frame 4 and the overhead conductor, making it easier for the upper wheel frame 4 to disengage.
[0034] In the embodiment, as shown in Figure 3 , the lower wheel frame 5 can also be replaced by an electric lifting push - rod assembly. The piston end of the electric push - rod 15 is connected to the upper wheel frame 4, and the bottom of the electric push - rod is connected to the corresponding position of the end joint 9 or the intermediate joint 10. By operating the electric push - rod 15, the labor intensity of the operators can be reduced.
[0035] In order to achieve quick disassembly and assembly operations on the line, at least one D - type pin is provided at the connection between the upper wheel frame 4 and the lower wheel frame 5. To improve safety performance, an auxiliary support 11 that can enhance the support strength is provided at the bottom of the seat board 3.
[0036] During use, the aerial line inspection operators first hang the three pulleys on the overhead conductor, then sit on the seat board 3 and move along the conductor by using hand as power. When encountering spacer dampers or other obstacles, open the D - type pin 8 of the frontmost group of upper wheel frames, disengage the upper wheel frame from the overhead conductor, and continue to move forward. When the middle group of upper wheel frames reaches in front of the spacer damper, hang the frontmost group of upper wheel frames back on the overhead conductor again, then disengage the middle group of upper wheel frames from the overhead conductor, and continue to move forward. When the rearmost group of upper wheel frames reaches in front of the spacer damper, hang the middle group of upper wheel frames back on the overhead conductor again, and then disengage the rearmost group of upper wheel frames from the overhead conductor. During the operation process, the aerial line inspection operators control the adjustment of the center - of - gravity position by slightly moving left and right on the seat board 3, and cooperate to complete the operation of hanging and disengaging the upper wheel frame 4 from the overhead conductor. And so on, the line inspection operation on the line can be completed. Because there are always two wheel frames connected to the overhead conductor, the staff will not fall, ensuring safety. At the same time, the structure is simple and the self - weight is very light, which is convenient for the operators to carry and use.
[0037] The above - described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
