Description

Technical Field

[0001] This invention relates to the field of contact wire delamination detection technology, specifically a rigid suspension contact wire delamination detection device. Background Technology

[0002] The copper contact wire of the railway may detach from the clamp of the busbar due to factors such as substandard installation quality, thermal expansion and contraction, or impact from the pantograph. Once detached from the groove, the pantograph will not be able to make normal contact with the contact wire, causing the train to lose power and easily leading to accidents such as pantograph-catenary collision and arcing that endanger the safety of train operation. Therefore, it is necessary to conduct groove detachment detection on the contact wire on the busbar.

[0003] Existing technologies generally use laser measuring instruments to measure the height of the contact wire. Based on the measured height, the system determines whether the contact wire has deviated from the busbar jaws, thus indirectly detecting whether the contact wire has come off the groove. When the clamping force of the busbar jaws is insufficient or there are defects, the static contact wire may still be in the jaw position. However, when the train is running and the pantograph and contact wire are subjected to impact forces, the contact wire will loosen and come off the groove. This type of detection device is mainly used when the contact wire is static and cannot be used to detect whether the contact wire has come off the groove under dynamic conditions, which is not conducive to improving the accuracy of the contact wire coming off the groove detection results. Summary of the Invention

[0004] The purpose of this invention is to provide a rigid suspension contact wire derailment detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rigid suspension contact wire derailment detection device, comprising:

[0007] The carrier is snapped onto the outside of the busbar to support the entire detection device; the carrier includes a carrier plate.

[0008] A clamping and traction mechanism is arranged on the top of the carrier plate to clamp the contact wire and pull the contact wire to check whether the contact wire is loose. The clamping and traction mechanism includes a movable column that is slidably connected to the carrier plate. A lifting plate is fixed on the top of the movable column. Two support plates are fixed on both sides of the movable column. A connecting shaft is rotatably connected between one end of the two support plates and between the other ends of the two support plates. A clamping wheel is fixed on the top of the connecting shaft.

[0009] A laser measuring instrument, mounted on top of the movable column, is used to measure the position and height of the contact wire;

[0010] Motor 2 is fixed to the bottom of the carrier plate, and the output end of motor 2 is fixed with a lead screw that is screwed into the movable column;

[0011] Two marking mechanisms are arranged between the lifting plate and the corresponding connecting shaft to mark the contact line of the grooving.

[0012] Furthermore, a connecting block one, which is fixed to the movable column, is fixed between the two trays, and a connecting block two is fixed between two adjacent trays.

[0013] Furthermore, a pulley is fixed at the position of the connecting shaft between the two support plates, and a synchronous belt is used to drive the two pulleys on the same support plate.

[0014] Furthermore, the clamping and traction mechanism also includes two motors that are fixedly installed with the corresponding position trays, and the motors can drive the corresponding position connecting shafts to rotate.

[0015] Furthermore, the clamping wheel is fixedly inserted into the connecting shaft at a position off-center, and the thickness of the clamping wheel at the eccentric long end is greater than the thickness at the eccentric short end.

[0016] Furthermore, the vehicle also includes:

[0017] Two positioning plates are fixed to the top of the support plate. Both ends of the positioning plates are movably inserted with studs, and one end of each stud is rotatably connected to a roller.

[0018] Two L-shaped rods are slidably inserted into corresponding positioning plates, and one end of each L-shaped rod is rotatably connected to a roller.

[0019] Two curved rods are fixed to both sides of the carrier plate.

[0020] Furthermore, both the stud and the L-shaped rod are screwed together with nuts, and the bottom of the carrier plate is fixed with an i-shaped plate capable of supporting the second motor.

[0021] Furthermore, a torque sensor is installed at the output end of the second motor.

[0022] Furthermore, the identification mechanism includes:

[0023] The piston shaft is slidably connected to the corresponding clamping wheel. The clamping wheel has a cylindrical chamber inside for the piston shaft to slide in. One end of the cylindrical chamber is connected to a connecting pipe.

[0024] A three-way pipe is connected and fixed to a connecting pipe, and a flexible hose 1 and a flexible hose 2 are connected and fixed to the three-way pipe.

[0025] A water tank is fixed to a carrier plate, and the water tank is connected and fixed to a hose.

[0026] The marking tube is arranged inside the lifting plate, and the marking tube is rotatably connected to the flexible hose.

[0027] Furthermore, one-way valves are installed at both ends of the three-way pipe near hose one and hose two, a piston is fixed at one end of the piston shaft, and a return spring is fixed between the piston and one end of the cylindrical chamber.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. By installing the carrier onto the busbar, a laser measuring instrument is mounted on the carrier plate via a movable column. The laser measuring instrument can measure the position and height of the contact wire on the busbar. When the measured height value is different from the standard height of the contact wire at the clamp of the busbar, it indicates that the contact wire has deviated from the mounting slot of the clamp. Thus, by measuring the height of the contact wire in a static state with the laser measuring instrument, it is possible to indirectly determine whether the contact wire has deviated from the slot. Furthermore, the carrier can move under the contact wire with the laser measuring instrument to measure the position and height of different areas of the contact wire, which is convenient for detecting whether long-distance contact wires have deviated from the slot.

[0030] 2. Two support plates are fixed on both sides of the movable column. Two clamping wheels are eccentrically rotated between two adjacent support plates via a connecting shaft. The rotation of the screw drives the movable column to move the clamping wheels on multiple support plates to the outside of the contact line. The motor drives the connecting shaft to rotate, causing the eccentric long end of the clamping wheel to rotate and abut against the contact line, thereby clamping multiple clamping wheels on the outside of the contact line. The rotation of the screw causes the movable column to move down through the support plates, thereby causing the multiple clamping wheels clamped on the outside of the contact line to have a tendency to pull the contact line down. If the clamping force of the busbar jaws is insufficient, the contact line will be clamped by the clamping wheels and pulled down. At this time, the laser measuring instrument can measure the height change of the down-moving contact line to determine the contact line derailment.

[0031] The motor drives the connecting shaft to rotate in the opposite direction, causing the eccentric long end of the clamping wheel to leave the contact line, thus freeing the clamping wheel from holding the contact line. The screw rotates in the opposite direction, driving the movable column to move the lifting plate upward. The lifting plate can push the contact line upward. If the clamping force of the busbar jaws is insufficient, the contact line will be pushed upward by the lifting plate. Similarly, the laser measuring instrument can measure the height change of the upward-moving contact line to determine whether the contact line has come out of the groove. Thus, the laser measuring instrument can indirectly determine whether the contact line has come out of the groove by measuring the height of the contact line under dynamic conditions.

[0032] 3. The contact wire is held by clamping wheels, and then the clamping wheels are driven to move downward to give the contact wire a downward traction force. The contact wire is pushed up by the lifting plate to give the contact wire an upward pushing force. This simulates whether the contact wire has derailed under external impact. By combining the derailment detection under both dynamic and static working conditions, the accuracy of the contact wire derailment detection results can be improved.

[0033] 4. A piston shaft is slidably inserted into the outside of some clamping wheels. When one end of the piston shaft rotates with the clamping wheel to the outside of the contact line, the piston shaft is squeezed by the contact line and moves towards the clamping wheel. The piston at the end of the piston shaft can squeeze the pigment solution in the cylindrical chamber. The pigment solution is delivered to the opening of the marking tube through the connecting pipe and the hose. The top surface of the lifting plate is brought into contact with the bottom surface of the contact line in advance. At this time, the pigment solution at the opening of the marking tube can be applied to the contact line, which is convenient for marking the contact line after grooving and makes it easier for subsequent construction personnel to find the grooving position and repair the contact line.

[0034] After the clamping wheel rotates away from the contact line with the piston shaft, the compression force of the return spring drives the piston shaft to move out of the clamping wheel. The piston at one end of the piston shaft moves towards the return spring, causing the pigment solution in the water tank to be drawn through the hose into the connecting pipe and the cylindrical chamber for subsequent marking. This allows the marking mechanism to mark different positions on the contact line multiple times. Different colors of pigment solution can be filled in the water tanks of the two marking mechanisms. When the contact line detaches from the groove while static, one marking mechanism can be used to mark one color. When the contact line detaches from the groove while dynamic, another marking mechanism can be used to mark another color, thus distinguishing the type of detachment of the contact line by using different colored pigment solutions.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1, please refer to Figure 1 - Figure 8 In this embodiment of the invention, a rigid suspension contact wire derailment detection device includes a carrier 100 clamped and installed outside a busbar. The carrier 100 includes a carrier plate 110. A clamping and traction mechanism 200 is provided on the top of the carrier plate 110. The clamping and traction mechanism 200 includes a movable column 210 slidably connected to the carrier plate 110. A lifting plate 211 is sleeved and fixed on the top of the movable column 210. Two mutually fixed support plates 220 are fixed on both sides of the movable column 210. A connecting shaft 230 is rotatably connected between one end of two adjacent support plates 220 and between the other ends of two support plates 220. A clamping wheel 240 is eccentrically fixed on the top of the connecting shaft 230. A laser measuring instrument 300 is embedded and fixed in the top of the movable column 210. A second motor 400 is fixedly installed on the bottom of the carrier plate 110. A lead screw 410 is fixed at the output end of the second motor 400. A threaded hole groove is opened at the bottom of the movable column 210 to be screwed and connected to the lead screw 410.

[0046] Specifically, by installing the laser measuring instrument 300 inside the movable column 210, which is positioned below the contact wire, the laser measuring instrument 300 can directly measure the static height of the contact wire, thus facilitating the determination of whether the contact wire has deviated from the standard height due to groove wear. The movable column 210, along with the lifting plate 211, supports the contact wire upwards, facilitating the detection of whether the contact wire has deviated from the groove after being subjected to an upward impact force. The eccentric long ends of multiple clamping wheels 240 rotate to abut against the contact wire, and the multiple clamping wheels 240 clamp the contact wire from both sides. The movable column 210, along with the multiple clamping wheels 240, moves downwards, subjecting the contact wire to a downward traction force, facilitating the detection of whether the contact wire has deviated from the groove after being subjected to a downward traction force. This enables the detection of whether the contact wire has deviated from the groove under both static and dynamic conditions, which helps improve the accuracy of the contact wire degrooving detection results.

[0047] like Figure 5 As shown, in this embodiment, a connecting block 221 is fixedly connected between the two pallets 220 at the lower position. The connecting block 221 is sleeved and fixed to the movable column 210, and a connecting block 222 is fixed between two adjacent pallets 220, so that multiple pallets 220 can be supported and fixed on the movable column 210, which facilitates the movable column 210 to move down with the clamping wheels 240 on the multiple pallets 220.

[0048] like Figure 5 and Figure 6 As shown, in this embodiment, the top of the movable column 210 is provided with a rectangular hole for mounting the laser measuring instrument 300. The top surfaces of the lifting plate 211 and the movable column 210 are set in an arc shape that matches the shape of the bottom surface of the contact line, so that the lifting plate 211 and the movable column 210 can contact the bottom end of the contact line. The clamping and traction mechanism 200 also includes two motors 250 that are fixedly installed with the corresponding support plate 220. The motors 250 can drive the corresponding connecting shaft 230 to rotate.

[0049] In this embodiment, specific reference is made. Figure 5 A pulley 231 is fixed at the position of the connecting shaft 230 between the two support plates 220. A synchronous belt 2311 is connected between the two pulleys 231 on the same support plate 220. When it is necessary to clamp and fix the contact line with multiple eccentrically arranged clamping wheels 240, the output end of the motor 250 drives one connecting shaft 230 to rotate. Under the meshing transmission action of the pulley 231 and the synchronous belt 2311, the connecting shaft 230 drives multiple clamping wheels 240 to rotate simultaneously. The direction of rotation is indicated by the arc arrow in the figure, so that the multiple clamping wheels 240 can clamp and fix on the outside of the contact line. A rubber sleeve is fixed on the outside of the clamping wheel 240. The rubber sleeve can improve the tightness of the contact between the clamping wheel 240 and the contact line.

[0050] like Figure 1 and Figure 5 As shown, in this embodiment, the clamping wheel 240 is inserted and fixed to the connecting shaft 230 at a position off-center, so that when the eccentric long end of the clamping wheel 240 rotates to the outside of the contact line, it can abut against the contact line (see reference). Figure 8 (Diagram showing the state of the clamping wheel 240 clamping the contact wire). When the eccentric short end of the clamping wheel 240 rotates to the outside of the contact wire, it does not contact the contact wire (refer to...). Figure 8 (Diagram showing the state of the clamping wheel 240 disengaging from the contact line).

[0051] In this embodiment, the thickness at the eccentric long end of the clamping wheel 240 is greater than the thickness at the eccentric short end, as described in the specification. Figure 1 At this point, the lifting plate 211 supports the contact line. The eccentric short end of the clamping wheel 240 rotates to a position close to the contact line, which will not hinder the lifting plate 211 from pushing the contact line upward. At the same time, the thickness of the eccentric short end of the clamping wheel 240 is small. If the contact line loosens at the jaws, the movable column 210 can move the lifting plate 211 upward along with the contact line. At this time, the area of ​​the clamping wheel 240 with smaller thickness will not contact the busbar jaws during the upward movement, preventing the clamping wheel 240 from interfering with the upward movement of the lifting plate 211. When it is necessary for the clamping wheel 240 to clamp the contact line, the thickness of the eccentric long end of the clamping wheel 240 is larger. Rotating the area with larger thickness to the outside of the contact line allows the clamping wheel 240 to contact the contact line over a larger area, which is beneficial to improving the firmness of the clamping wheel 240 in clamping the fixed contact line.

[0052] like Figure 1 and 4 As shown, in this embodiment, the carrier 100 also includes two positioning plates 120 fixedly connected to the carrier plate 110. Both ends of the positioning plate 120 are movably inserted with studs 130. One end of the stud 130 is rotatably connected with a roller 131. An L-shaped rod 140 is slidably inserted into the middle of the positioning plate 120. One end of the L-shaped rod 140 is rotatably connected with a roller 141. The studs 130 and the L-shaped rod 140 are both installed by screwing on nuts.

[0053] In this embodiment, when the carrier 100 needs to be installed on the busbar, the carrier 100 is supported from below the busbar upwards, so that the roller 131 is arranged on the outside of the busbar. Then, the stud 130, along with the roller 131, is moved closer to the outside of the busbar, so that the multiple rollers 131 are moved above the jaws of the busbar. Then, the multiple studs 130 are fixed to the positioning plate 120 with nuts. Next, the two L-shaped rods 140 are pulled upwards, so that the roller 2 141 on the L-shaped rod 140 rolls against the lower groove of the jaws. The L-shaped rod 140 is fixed to the positioning plate 120 again with nuts, thereby limiting and fixing the entire carrier 100 on the busbar, and both the roller 131 and the roller 2 141 on the carrier 100 can roll along the busbar.

[0054] In this embodiment, refer to Figure 4 Both sides of the carrier plate 110 are fixed with arc-shaped rods 150, and a ring is fixed in the middle of the arc-shaped rods 150. The ring is connected and fixed to an external traction rope. When it is necessary to move the carrier 100 along the busbar with the entire detection device, the user can pull the traction rope to move the arc-shaped rods 150 along the busbar with the carrier 100.

[0055] In this embodiment, refer to Figure 4 Two connecting rods 113 are fixed between the carrier plate 110 and the positioning plate 120. The connecting rods 113 securely support and fix the positioning plate 120 above the carrier plate 110.

[0056] like Figure 1 and 3 As shown, in this embodiment, a U-shaped plate 111 is fixed at the bottom of the carrier plate 110 to support and fix the second motor 400. A torque sensor 411, a prior art component, is installed at the output end of the second motor 400. The torque sensor 411 can be connected to an external controller. The rotational torque of the output end of the second motor 400 can be known through the torque sensor 411. A U-shaped frame 112 is fixed at the bottom of the carrier plate 110 and is rotatably connected to the output end of the second motor 400. The U-shaped frame 112 can improve the stability of the rotation of the output end of the second motor 400.

[0057] In this embodiment, after multiple clamping wheels 240 cooperate to clamp and fix the contact wire, the external controller can drive the motor 400 to rotate the lead screw 410 according to a predetermined torque value a. If the clamping force of the bus jaws is insufficient and the contact wire becomes loose, the torque value a can cause the movable column 210 to rotate downward, thereby causing the multiple clamping wheels 240 to move away from the jaws with the loose contact wire. However, when the clamping force of the contact wire on the bus meets the installation requirements, the torque value a cannot cause the movable column 210 to rotate downward, and the multiple clamping wheels 240 remain clamped and fixed outside the contact wire. At this time, the external controller detects that the motor 400 is in an overload state and can automatically cut off the power to the motor 400 to protect it, thereby preventing the contact wire with the clamping force meeting the installation requirements from being pulled out. The specific torque value a can be adjusted and set according to the clamping force of the contact wire. The torque sensor 411 and the controller are existing technology components, and their specific working principles will not be described in detail.

[0058] In this embodiment, when a larger traction force is needed to pull the contact wire downward and then clean the debris between the contact wire and the busbar, the torque value a of the motor 400 can be increased. The increased torque value can drive the movable column 210 to rotate downward, and the movable column 210 pulls the contact wire out of the busbar jaws through multiple clamping wheels 240.

[0059] In this embodiment, when it is necessary for the motor 400 to drive the lead screw 410 to rotate so that the movable column 210 can move the lifting plate 211 upward to lift the contact wire, the torque of the motor 400 is similarly preset so that the torque can only push the loose contact wire upward out of the busbar jaws. For the contact wire that is properly clamped, the output torque of the motor 400 is not sufficient to drive the movable column 210 upward to move the lifting plate 211 upward to lift the contact wire.

[0060] Example 2: Based on Example 1, in order to mark the location of the contact wire that has come off the groove, it is convenient to target and repair the contact wire at the location of the groove later.

[0061] like Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, the marking mechanism 500 includes a piston shaft 510 slidably connected to a clamping wheel 240 at a corresponding position. The clamping wheel 240 has a cylindrical chamber 241 for sliding of the piston shaft 510. A piston is fixed to one end of the piston shaft 510. A return spring 511 is fixed between the piston and one end of the cylindrical chamber 241. A connecting pipe 520 is fixedly connected to one end of the cylindrical chamber 241. The connecting pipe 520 is arranged inside the connecting shaft 230 at a corresponding position. A three-way pipe 530 is rotatably connected to the bottom end of the connecting pipe 520. A hose 1 531 and a hose 2 532 are fixedly connected to the three-way pipe 530. One end of the hose 1 531 is fixedly connected to a water tank 540 fixed to the carrier plate 110. The water tank 540 contains pigment solution. One end of the hose 2 532 is fixedly connected to a marking tube 550. The marking tube 550 is installed inside the lifting plate 211.

[0062] In this embodiment, when it is necessary to mark the contact wire that has been removed from the groove, motor 250 drives a clamping wheel 240 of the marking mechanism 500 to... Figure 5 The reverse rotation of the arc-shaped arrow causes the piston shaft 510 to squeeze the pigment solution inside the cylindrical chamber 241 under the pressure of the contact line. The pigment solution flows through the connecting pipe 520 and the second hose 532 to the opening of the marking pipe 550. The solution at the opening can stain the outside of the contact line, thus marking the contact line. During this process, the return spring 511 is in a stretched state. After the clamping wheel 240 rotates in the opposite direction and leaves the contact line, the elastic force of the return spring 511 will drive the piston shaft 510 to return the piston to the initial position. During this process, the piston draws the pigment solution inside the water tank 540 into the cylindrical chamber 241 through the first hose 531 for subsequent marking.

[0063] In this embodiment, refer to Figure 7One-way valves are installed at both ends of the three-way pipe 530 near the first hose 531 and the second hose 532, so that the first hose 531 can only deliver solution to the connecting pipe 520 in one direction, and the second hose 532 can only output solution from the connecting pipe 520 in one direction.

[0064] In this embodiment, refer to Figure 2 The outer side of the tee pipe 530 is fitted with a fixing block 223 that is fixed to the support plate 220, so that the tee pipe 530 will not rotate synchronously with the connecting pipe 520 and the connecting shaft 230 during the rotation of the connecting shaft 230 carrying the connecting pipe 520.

[0065] In this embodiment, refer to Figure 7 A sleeve 552 is fixedly fitted to the outside of the marking tube 550. The sleeve 552 can hold excess solution. The sleeve 552 is detachably connected to the lifting plate 211. A tray 551 is fixedly connected to the opening of the marking tube 550. The tray 551 can increase the marking area. The top surfaces of both the tray 551 and the sleeve 552 are set to be arc-shaped to fit the bottom outer side of the contact line, so that the tray 551 and the sleeve 552 can make tight contact with the contact line after the lifting plate 211 contacts the contact line.

[0066] In this invention, the clamping wheel 240 also has other additional functions, as described in the specification. Figure 8 This allows multiple clamping wheels 240 to move downwards, causing the clamping wheel 240 on one side of the contact line to leave the contact line, while the other side of the contact line contacts the thicker part of the eccentric long end of the clamping wheel 240. This enables the clamping wheel 240 on one side to rotate and squeeze one side of the contact line, making it convenient to detect whether the contact line is loose in the jaws of the busbar.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0068] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
