Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of contact network defect detection equipment, and particularly relates to a contact network defect detection equipment capable of advancing across obstacles. BACKGROUND
[0002] The contact network is a high-voltage transmission line provided for a pantograph to draw current, which is also called as overhead cable or overhead cable, and is a main structure of railway electrification engineering and a special form of power transmission line for supplying power to electric locomotives. Since the contact network is exposed to the outdoor environment for a long time, the contact network is affected by various environmental factors (such as weather, pollution, etc.) and mechanical stress in the operation process, and thus cracks, corrosion, wear and other defects can occur. If these defects are not found and treated in time, the defects can cause equipment failure, and even cause the pantograph to be separated from the electric locomotive, power supply to be interrupted and other serious problems. In order to ensure the safe operation of the contact network facilities, the contact network needs to be periodically detected by defect detection. Through the defect detection, the potential defects can be found in time, and the occurrence of equipment failure can be prevented.
[0003] Most of the traditional contact network defect detection equipment relies on ground inspection or track inspection. Although these methods can better complete the defect detection task under normal circumstances, they are not capable enough when encountering special situations such as natural disasters. Natural disasters often lead to extremely complex and uncertain road conditions. For example, an earthquake can cause road collapse or rupture, and a flood can flood the road or destroy the bridge. Under these extreme conditions, the traditional inspection method is often difficult to pass through or cannot pass through the disaster area, which makes the defect detection of the contact network particularly difficult. In order to overcome this problem, some people propose a scheme of using a UAV for inspection. The UAV has the advantages of flexible flight, wide coverage, high inspection efficiency, and can replace the traditional inspection method to a certain extent. However, the endurance of the UAV is limited and cannot maintain long-term flight, which limits its inspection range and efficiency. Therefore, there is an urgent need for a contact network defect detection equipment capable of overcoming complex terrain and obstacles, having high flexibility and adaptability, to meet the defect detection needs in special situations such as natural disasters.

DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.
[0032] Embodiment one
[0033] Please refer to Figures 1-9The embodiment of the present application discloses a contact net defect detection equipment capable of advancing across obstacles, which comprises a vehicle body 100, four supporting arms 110 fixedly connected to the outer side walls of the vehicle body 100 in symmetry, a propeller 120 fixedly installed at the end of each supporting arm 110, a base 130 fixedly connected to the bottom surface of the vehicle body 100, two moving mechanisms 200 arranged on the bottom surface of the base 130, a fixed seat 210, a clamping rod 211 rotatably connected to the opposite side walls of the fixed seat 210, a square sleeve 212 fixedly connected to the top surface of the fixed seat 210, a square rod 213 slidably inserted into the square sleeve 212, the top end of the square rod 213 fixedly connected to the bottom surface of the base 130, a driving unit 220 and a moving unit 230 slidably sleeved on the outer wall of each clamping rod 211, an installation box 221, a fixed plate 222 fixedly connected to the bottom surface of the driving unit 220, a circular hole formed in the side wall of the fixed plate 222 and slidably sleeved with the clamping rod 211, a rotating shaft rotatably connected to the side wall of the installation box 221 away from the fixed seat 210, a gear one 223 fixedly connected to the other end of the rotating shaft, a servo motor 225 fixedly connected to the inside of the installation box 221, the motor shaft of the servo motor 225 penetrating through the side wall of the installation box 221 and drivingly connected to the end of the rotating shaft, a baffle 231, the moving wheel 232 fixedly connected to the side wall of the baffle 231 away from the fixed seat 210, a sleeve pipe 233 fixedly connected to the side wall of the baffle 231 close to the fixed seat 210, the side wall of the sleeve pipe 233 rotatably connected to the side wall of the fixed plate 222, a gear two 234 fixedly sleeved on the outer wall of the sleeve pipe 233, and the gear two 234 meshingly drivingly connected with the gear one 223.
[0034] Specifically, the front and rear positions of the bottom surface of the base 130 are provided with moving mechanisms 200, each moving mechanism 200 includes two moving units 230, and the four moving units 230 constitute the wheels of the vehicle body 100. The side wall of the baffle 231 is in contact with the side wall of the steel rail. The servo motor 225 is started. The motor shaft of the servo motor 225 is driven to rotate the rotating shaft. The rotating shaft rotates, so that the gear one 223 rotates with the rotating shaft. The gear one 223 is engaged with the gear two 234, so that the sleeve 233 rotates. The side wall of the sleeve 233 is fixedly connected with the baffle 231, and the other side of the baffle 231 is fixedly connected with the moving wheel 232. The arc detection unit 250 is started. The moving wheel 232 rotates, so that the vehicle body 100 moves at a constant speed along the steel rail. When the front section of the road is blocked by natural disasters and the like, so that it cannot pass directly, four propellers 120 are started to drive the device to fly over the obstacle. After flying away from the obstacle, in order to save energy, the device is controlled to descend. The length of the two connecting rods 211 connected together is longer than the distance between the two steel rails. When the device descends, first control the position between the two steel rails, and then slowly land, so that the two connecting rods 211 on both sides are respectively clamped on the two steel rails. Until the moving wheel 232 is in contact with the steel rail again, the servo motor 225 can be started again to make the device move along the steel rail.
[0035] As shown in Figures 2-4 In this embodiment, the bottom surface of the base 130 is fixedly connected with four rotating seats one 131 which are symmetrical to each other. The inside of the four rotating seats one 131 are rotatably connected with rotating rods 132. The top surface of the four mounting boxes 221 are fixedly connected with rotating seats two 224. The other end of the four rotating rods 132 are rotatably connected with the inside of the four rotating seats two 224. The moving mechanism 200 further includes an electric telescopic rod 240. The side wall of the two mounting boxes 221 in the moving mechanism 200 are fixedly connected with supporting rods 226. The bottom end of the electric telescopic rod 240 is fixedly connected with the side wall of one of the supporting rods 226. The output end of the electric telescopic rod 240 is fixedly connected with the side wall of the other supporting rod 226.
[0036] In the embodiment, when the propeller 120 is started to make the device fly away from the steel rail, the electric telescopic rod 240 is controlled to retract, and since the rotating rod 132 is rotationally connected with the rotating seat two 224 and rotationally connected with the rotating seat one 131, when the electric telescopic rod 240 is retracted, the two driving units 220, that is, the two moving units 230, move along the connecting rod 211 to the fixed seat 210 and approach each other, and the square rod 213 is stretched out from the inside of the square sleeve 212. At this time, when landing is needed, the edges of the connecting rod 211 are reserved with enough positions to contact the steel rail, facilitating landing. After the device is controlled to land and the connecting rod 211 is lapped on the steel rail, the electric telescopic rod 240 is controlled to be lengthened, the electric telescopic rod 240 pushes the two supporting rods 226, so that the two driving units 220 move along the connecting rod 211 to the outer ends thereof, respectively, the square rod 213 is retracted into the inside of the square sleeve 212, until the side walls of the two baffles 231 abut against the inner side walls of the two steel rails, respectively, at this time, the moving wheels 232 are lapped on the surfaces of the steel rails, the servo motor 225 is started, and the device can be driven to continue moving.
[0037] As shown in Figure 4 and Figures 7-8 In the embodiment, the outer walls of the two connecting rods 211 are provided with sliding grooves 2111, the inner walls of the two sleeve pipes 233 are fixedly connected with sliding blocks 2331, and the two sliding blocks 2331 are slidably connected with the two sliding grooves 2111, respectively.
[0038] In specific implementation, since one end of the connecting rod 211 is rotationally connected with the fixed seat 210, the baffle 231 / moving wheel 232 and the sleeve pipe 233 are sleeved on the outer wall of the connecting rod 211, the sliding block 2331 on the inner wall of the sleeve pipe 233 is matched with the sliding groove 2111, so that when the servo motor 225 is started, the gear one 223 can drive the connecting rod 211 to rotate, and when the electric telescopic rod 240 is lengthened or retracted, the sliding block 2331 slides along the inside of the sliding groove 2111, so that the movement of the driving unit 220 and the moving unit 230 on the connecting rod 211 is more stable.
[0039] As shown in Figure 8 In the embodiment, the moving wheel 232 is in the shape of a cone, and the outer wall of the moving wheel 232 is covered with rubber.
[0040] In particular implementation, the outer wall of the moving wheel 232 is covered with rubber, and the rubber material has good friction performance, which can increase the friction between the contact surface of the moving wheel 232 and the steel rail, and ensure that the moving wheel 232 can stably push the vehicle body 100 to move when rotating. Since the device will first collect the electric telescopic rod 240 when taking off, it is convenient for subsequent landing alignment with the steel rail. The shape of the moving wheel 232 is set as a cone, and the thin end of the conical moving wheel 232 faces the outer end of the clamping rod 211, which reduces the moving resistance, so that after the clamping rod 211 is clamped on the surface of the steel rail when landing, the moving wheel 232 can better move along the clamping rod 211 and abut against the surface of the steel rail.
[0041] As shown in Figures 1-2 In this embodiment, the top surface of the vehicle body 100 is provided with a cab 140, and the top surface of the cab 140 is fixedly connected with two cameras 150 which are symmetrically arranged.
[0042] In particular implementation, the top surface of the vehicle body 100 is provided with a cab 140, which can allow the staff to travel together and perform some auxiliary operations. When the staff finds that the overhead contact system fails, the staff can timely get off to handle it. When encountering an obstacle, the operator can leave the cab 140 to remotely control the device to fly over the obstacle. The top surface of the cab 140 is provided with two cameras 150 which are respectively directed to the front and rear, and are used to transmit the photos and situation of the overhead contact system in real time, which is convenient for recording.
[0043] Embodiment two
[0044] On the basis of embodiment one, in order to make the device move more stably when moving on the steel rail and avoid falling when turning.
[0045] As shown in Figure 4 and Figure 9 In this embodiment, the side wall of the two installation boxes 221 away from the electric telescopic rod 240 is fixedly connected with an arc detection unit 250. The arc detection unit 250 comprises a connecting frame 251, the top end of the connecting frame 251 is fixedly connected with the side wall of the installation box 221, the bottom side of the connecting frame 251 is fixedly connected with a rotating seat three 252, the rotating seat three 252 is rotatably connected with a connecting rod 253, the other end of the connecting rod 253 is rotatably connected with a contact wheel 254 through a torsional spring, and the connecting rod 253 drives the contact wheel 254 to contact and abut against the inner side wall of the track through the torsional spring.
[0046] In actual implementation, the two arc detection units 250 are fixed on the side walls of the two mounting boxes 221, and the connecting frame 251 extends in front of the moving units 230, and the positions of the contact wheels 254 correspond to the positions of the baffles 231. When the baffle 231 is attached to the inner side wall of the rail, the surface of the contact wheel 254 is also attached to the inner side wall of the rail. An angle sensor can be installed on the arc detection unit 250. When the device encounters a curve in front during the forward movement, the contact wheel 254 located at the front will preferentially contact the curved rail, so that the connecting rod 253 and the rotating seat three 252 are deflected. The angle sensor transmits to the control center, so that the rotating speed of the servo motors 225 on both sides is changed to form a speed difference, so that the device turns along the track.
[0047] The working principle of the present application is as follows: in the normal non-obstacle section, the device is maintained on the rail, the left moving wheels 232 in the two moving mechanisms 200 below the base 130 are in contact with the rail on the left, and the right moving wheels 232 in the two moving mechanisms 200 are in contact with the rail on the right. At this time, the device is in a static state. Start the servo motor 225. The motor shaft of the servo motor 225 drives the rotating shaft, which drives the gear one 223 to rotate. The rotating gear one 223 is engaged with the gear two 234, so that the gear two 234 rotates. The gear two 234 is sleeved and fixed on the outer wall of the sleeve 233, and the side wall of the sleeve 233 is fixedly connected to the side wall of the baffle 231. The other side of the baffle 231 is fixedly connected with the moving wheel 232 in contact with the surface of the rail. At this time, the moving wheel 232 will rotate due to the start of the servo motor 225, so that the device moves forward along the rail at low speed, and the surrounding contact network is inspected and detected. The arc detection units 250 provided in front of the four moving units 230 are in a monitoring state, ready to respond to changes in the track. The surface of the contact wheel 254 is attached to the side wall of the rail. When the track turns, the contact wheel 254 located in front of the moving wheel 232 will preferentially contact the curved rail side wall. The curved rail side wall forms a compression on the contact wheel 254, and the connecting rod 253 is deflected with the rotating seat three 252 as the axis. A sensor is installed on the arc detection unit 250. The sensor detects the change and transmits a signal to the control center. The control center adjusts the rotating speed of the servo motors 225 on both sides according to the signal to form a speed difference, so that the device smoothly turns along the track. For example, if you want to turn right, you can appropriately increase the rotating speed of the right moving wheel 232, and at the same time, reduce the rotating speed of the left moving wheel 232. In this way, the device will turn right because the right moving wheel 232 rotates faster. Conversely, if you want to turn left, you can appropriately increase the rotating speed of the left moving wheel 232, and at the same time, reduce the rotating speed of the right moving wheel 232.
[0048] When the current road section appears obstacles due to natural disasters and the like and cannot directly pass, four propellers 120 are started to drive the device to rise and fly over the obstacles. At this time, the electric telescopic rod 240 is controlled to retract, and the driving units 220 (including the moving units 230) on both sides move along the connecting rods 211 to the fixed seat 210 direction to prepare for landing. After flying away from the obstacles, in order to ensure the endurance of the device, the device is controlled to descend. During the descending process, the position of the device is first controlled between the two steel rails, and then slowly lands. Because the driving units 220 and the moving units 230 on both sides are close to each other, the connecting rods 211 on both sides have a longer distance to contact the steel rails. When the connecting rods 211 on both sides are respectively connected to the steel rails on both sides, the electric telescopic rod 240 is controlled to extend to push the two supporting rods 226, so that the two driving units 220 (including the moving units 230) move along the two connecting rods 211 to the outer ends thereof, until the two moving wheels 232 are reconnected to the surfaces of the two steel rails, and the side walls of the two baffles 231 are respectively abutted with the inner side walls of the two steel rails. At this time, the servo motor 225 can be started again to make the device continue to move along the steel rails. At the same time, the arc detection unit 250 keeps working to ensure that the device can smoothly cope with any changes of the track. The top surface of the vehicle body 100 is provided with a cab 140, which allows the operator to travel with the device to assist in operation, such as emergency handling of catenary failure. When encountering obstacles in front, the operator can leave the cab 140 and fly over the obstacles by remotely controlling the device. The two cameras 150 on the top surface of the cab 140 are respectively directed to the front and rear to transmit the status of the catenary in real time for the operator to monitor and record.
