Description

Technical Field

[0001] The present invention relates to the technical field of switch machines, and in particular to an intelligent management device for hand-cranked tools of switch machines. Background Art

[0002] A switch machine is an important signal infrastructure equipment used to reliably switch the position of switches, change the direction of switch opening, lock the switch point rail, and reflect the position of switches. It can well ensure driving safety, improve transportation efficiency, and improve the labor intensity of drivers.

[0003] The function of the switch machine is to switch and lock the point rail (heart rail), change the opening direction of the turnout, and reflect the position of the point rail (heart rail) through the contact point. The switch machine is one of the important equipment to ensure the safety of railway transportation. If the switch machine fails to switch the turnout into place normally, it will affect the normal operation of the train. In serious cases, it may cause a train collision or derailment.

[0004] When the switch machine cannot be powered on and switched normally, the emergency treatment method is usually to manually switch the turnout into place by hand-cranking the motor shaft, and then do further processing after the train passes.

[0005] At present, if the hand-operated tool of the switch machine is missing and not discovered in time, when emergency manual switching of the turnout is required, it will cause problems that cannot be handled in an emergency.

[0006] In addition, for multi-machine traction turnouts, when manually operating a single switch machine, only the manually operated switch machine can be ensured to be in a manually powered-off state. However, the turnout may be suddenly electrically switched by other switch machines, thereby driving the hand-cranked shaft of the manually operated switch machine to rotate, which may further cause harm to the manual operator.

[0007] It should be noted that a multi-machine traction turnout is a group of turnouts with multiple traction points, each traction point is equipped with a switch machine. When the turnout is switched, multiple switch machines operate simultaneously to drive the point rail to another position. Summary of the invention

[0008] The purpose of the present invention is to provide an intelligent management device for hand-operated tools of a switch machine in view of the technical defects in the prior art.

[0009] To this end, the present invention provides a switch machine hand-operated tool intelligent management device, which includes a laterally distributed bottom plate;

[0010] A horizontally distributed base is provided at the top left end of the bottom plate;

[0011] Wherein, a static contact frame is provided on the rear side of the base;

[0012] A static contact group is arranged on the top of the static contact frame;

[0013] Wherein, above the top front side of the base, movable contact racks are arranged at intervals;

[0014] A moving contact group is arranged on the top of the moving contact frame;

[0015] The base vertical plates on the left and right sides of the top of the base are connected to the left and right vertical plates of the moving contact frame through a horizontally distributed linkage shaft;

[0016] The bottom plate is provided with a vertically distributed upper end cover and a lower end cover on the left and right sides of the base;

[0017] Wherein, the left and right sides of the lower part of the lower end cover are respectively connected to the right side of an identification sleeve and the left side of a guide tube;

[0018] Among them, a hand crank passes through the guide tube and the identification sleeve horizontally from right to left, and is plugged into the linkage shaft.

[0019] It can be seen from the technical solution provided by the present invention that, compared with the prior art, the present invention provides an intelligent management device for hand-cranked tools of a switch machine, which has a scientific structural design and can be used as a daily storage box for hand-cranked tools of a switch machine for easy management. After the hand crank handle is taken out manually, the circuit will be automatically cut off, which can further improve the safety of manual switch switching and avoid the problem of being unable to handle emergencies due to the lack of hand crank tools (i.e., hand crank handles), and has great production practical significance.

[0020] In addition, the device of the present invention has the ability to identify and prevent fraud. An identification sleeve with specific threads is provided in the device. Only hand-cranked tools (i.e., hand crank handles) with matching threads are allowed to pass through the identification hole (i.e., the inner hole of the identification sleeve). This can truly play a role in intelligent management of the hand-cranked tools of the switch machine and avoid the mistaken insertion of hand-cranked tools that do not match the switch machine.

[0021] In addition, in specific applications, by using the device of the present invention in parallel with other warning devices (such as warning lights, alarm bells, etc.), when the hand crank in the device of the present invention is not taken out, the dynamic and static contact groups are in a connected state, which is equivalent to a wire, and the warning device connected in parallel with it is in a short-circuited state and does not work; when the hand crank is taken out, the dynamic and static contact groups are in a disconnected state, so that the warning device can be powered normally and send out warning information;

[0022] In addition, the device of the present invention has a compact structure and is easy to install. The mechanical part only needs four screws to be installed on an external installation plane such as the wall in the control room, and the electrical part only needs to be connected in series to the common circuit of the switch motor line of the turnout control circuit (to play the role of a switch).

[0023] In specific application, by connecting the device of the present invention in series in the common circuit of the switch machine motor line of the turnout control circuit, when the hand crank is taken out, the outdoor switch machine control circuit can be automatically cut off to protect the safety of the operator. Therefore, the problem of safety risks in the prior art when manually operating a single switch machine in a multi-machine traction turnout can be solved. Power-off protection can be implemented when the switch machine is manually operated, which can effectively ensure personal safety when manually operating the switch machine.

[0066] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0067] See also Figures 1 to 20 , the present invention provides a smart management device for hand-operated tools of a switch machine, comprising a laterally distributed bottom plate 1;

[0068] A base 2 is disposed at the top left end of the bottom plate 1 and is distributed laterally;

[0069] Among them, a static contact frame 51 is provided on the rear side of the base 2;

[0070] A static contact group 52 is provided on the top of the static contact frame 51;

[0071] Among them, above the top front side of the base 2, there are movable contact frames 61 arranged at intervals;

[0072] A moving contact group 62 is provided on the top of the moving contact frame 61;

[0073] The base upright plates 203 on the left and right sides of the top of the base 2 are connected to the left and right upright plates of the movable contact frame 61 through a horizontally distributed linkage shaft 7;

[0074] The bottom plate 1 is provided with a vertically distributed upper end cover 91 and a lower end cover 92 on the left and right sides of the base 2;

[0075] The left and right sides of the lower portion of the lower end cover 92 (specifically, the left and right sides of the lower step hole 920) are connected to the right side of an identification sleeve 12 and the left side of a guide tube 13 respectively;

[0076] Among them, a hand crank 16, after passing through the guide tube 13 and the identification sleeve 12 (specifically the inner hole 122 of the identification sleeve) from right to left, is plugged into the linkage shaft 7 (specifically plugged into the square head 70 of the linkage shaft 7). Therefore, at this time, by rotating the hand crank 16 clockwise (or counterclockwise), the moving contact group and the static contact group can be connected (or disconnected).

[0077] In the present invention, in specific implementation, the bottom plate 1 is a rectangular flat plate;

[0078] A plurality of device mounting holes 101 are respectively provided at the front and rear sides of the right end of the base plate 1 for connecting with an external mounting plane (such as a wall) by means of bolts.

[0079] In the present invention, in a specific implementation, a base threaded hole 201 is provided at the bottom center of the base 2;

[0080] Two base mounting holes 202 are respectively provided at the left and right ends of the base 2 and are distributed front and back;

[0081] A glass bead screw 3 is installed in the threaded hole 201 of the base;

[0082] Four base mounting holes 202 are respectively mounted on the base plate 1 by screws;

[0083] The left and right sides of the top of the base 2 are provided with base upright plates 203 respectively;

[0084] On the left and right base vertical plates 203, there is a first flange bushing through hole 204 and a second flange bushing through hole 205 respectively.

[0085] The aperture of the second flanged bushing through hole 205 is larger than the aperture of the first flanged bushing through hole 204;

[0086] A first flanging bushing 41 and a second flanging bushing 42 are respectively embedded in the first flanging bushing through hole 204 and the second flanging bushing through hole 205 .

[0087] In the present invention, in a specific implementation, an "inverted U"-shaped wiring rack 510 is welded on the top surface of the static contact rack 51;

[0088] A static contact frame threaded hole 511 is provided at the left and right ends of the top front side of the static contact frame 51;

[0089] The bottom surface of the static contact frame 51 is provided with a foot hole 512 at both ends, and is mounted on the bottom plate 1 by screws;

[0090] The static contact assembly 52 (which is a special assembly for the switch machine) is mounted on the static contact frame threaded hole 511 on the top surface of the static contact frame 51 by two screws.

[0091] It should be noted that, for the present invention, the static contact group 52 includes an insulating static contact seat 521 and a three-pair contact sheet group;

[0092] Each pair of contact sheet groups includes a left contact sheet 522, a right contact sheet 523 and two connecting posts 524, and the left contact sheet 522 and the right contact sheet 523 are symmetrically distributed. The two connecting posts 524 are connected to the rear end of the left contact sheet 522 and the rear end of the right contact sheet 523 respectively. At the same time, there is a reserved horizontal gap between the front end of the left contact sheet 522 and the front end of the right contact sheet 523.

[0093] That is, it includes three left contact pieces 522, three right contact pieces 523 and six threaded terminals 524. The left contact pieces 522 and the right contact pieces 523 and the terminals 524 are all highly conductive. Each left contact piece 522 and the right contact piece 523 are respectively connected to a terminal 524 and are insulated from each other. The bottom of each terminal 524 is connected to the top of the static contact seat 521. The terminal 524 is allowed to be inserted with a wire loop and tightened with a nut. The left contact pieces 522 and the right contact pieces 523 are arranged alternately to form three groups of "V"-shaped switch pieces.

[0094] In the present invention, in specific implementation, the movable contact frame 61 is in an "inverted U" shape;

[0095] A moving contact frame threaded hole 611 is provided at the left and right ends of the top surface of the moving contact frame 61;

[0096] The left and right side vertical plates of the moving contact frame 61 are respectively provided with a spline hole 613 and a moving contact frame through hole 612;

[0097] The moving contact assembly 62 (special assembly for the switch machine) is mounted on the moving contact frame threaded hole 611 on the top surface of the moving contact frame 61 by two screws.

[0098] It should be noted that, in the present invention, the moving contact group 62 includes an insulated moving contact seat 621 and three moving contact posts 622 with good conductivity. The moving contact posts 622 are insulated from each other, and the bottom of each moving contact post 622 is connected to the top of the moving contact seat 621.

[0099] Among them, each moving contact column 622 is arranged to correspond to the horizontal gap between the front end of the left contact piece 522 and the front end of the right contact piece 523 of each pair of contact pieces in the static contact group 52 (for example, it is located directly in front, so that it is convenient to rotate and insert it between the front end of the left contact piece 522 and the front end of the right contact piece 523, and contact with the front end of the left contact piece 522 and the front end of the right contact piece 523).

[0100] In the present invention, it should be noted that the left contact piece 522 and the right contact piece 523 of the static contact group 52 are equivalent to the static contacts of the knife switch, and the moving contact column 622 of the moving contact group 62 is equivalent to the knife of the knife switch. Therefore, the moving contact group and the static contact group cooperate to connect or disconnect three circuits at the same time.

[0101] When the moving contact group 62 rotates with the moving contact frame 61 and falls between the "V"-shaped static contact pieces (i.e., the left contact piece 522 and the right contact piece 523), the adjacent left contact piece 522 and right contact piece 523 are connected. When the two are separated, the left contact piece 522 and the right contact piece 523 are in an open circuit state.

[0102] In a specific implementation, for the present invention, the hand crank 16 drives the square head 70 at the left end of the linkage shaft 7 to rotate, and the spline 73 on the linkage shaft 7 forces the moving contact frame 61 and the moving contact group 62 to rotate together.

[0103] In the present invention, the specific implementation is as follows: Figure 7c The right end of the linkage shaft 7 is a square head 70 which is consistent with the square head shape of the hand crank end of the motor shaft in the corresponding model of the switch machine that needs to be shaken by the hand crank 16;

[0104] It should be noted that the square groove 1632 of the hand crank 16 forms a plug-in relationship with the square head of the motor shaft in the existing switch machine so that the switch machine can be manually cranked; similarly, the square head 70 of the linkage shaft 7 must be consistent with it to be driven.

[0105] For the present invention, the square groove 1632 of the hand crank 16 drives the square head 70 of the linkage shaft 7 to rotate, and the spline 73 on the linkage shaft 7 forces the moving contact frame and the moving contact group thereon to rotate accordingly, thereby realizing the connection or disconnection between the moving and static contacts.

[0106] For the present invention, from the insertion direction of the hand crank 16 (i.e., insertion from right to left), the hand crank 16 is inserted into the guide tube 13 until the flat plate 162 is aligned with the limiting groove 133 of the guide tube 13, and then the linkage shaft 7 is driven clockwise to rotate the hand crank 16 to a horizontal position. At this time, the flat plate 162 enters the limiting groove 133, and the hand crank lock hole 1620 is aligned with the lock plate lock hole 180, allowing further padlocking at the lock hole.

[0107] In the present invention, four spherical grooves 71 and splines 73 are arranged around the middle of the linkage shaft 7;

[0108] The spline 73 of the linkage shaft 7 is used to match and connect with the spline hole 613 on the left vertical plate of the movable contact frame 61;

[0109] The left end of the linkage shaft 7 is provided with an external thread and a cotter pin hole 72;

[0110] The linkage shaft 7 passes through the second flanged bushing 42 embedded in the second flanged bushing through hole 205 of the base vertical plate 203, the through hole 612 on the right vertical plate of the moving contact frame 61, the spline hole 613 on the left vertical plate of the moving contact frame 61 and the first flanged bushing 41 embedded in the first flanged bushing through hole 204 of the base vertical plate 203, and is then connected to a stop nut 8.

[0111] In a specific implementation, the square head 70 at the right end of the linkage shaft 7 is plugged into the square groove 1632 inside the left end 1630 of the hand crank 16.

[0112] For specific implementation, see Figure 7a , the stop nut 8 has an open pin groove 801;

[0113] See also Figure 1 A cotter pin 19 passes through the cotter pin groove 801 and is inserted into the cotter pin hole 72 at the left end of the linkage shaft 7.

[0114] It should be noted that, for the present invention, the left threaded end of the linkage shaft 7 passes through the second flanged bushing 42 embedded in the second flanged bushing through hole 205 of the base vertical plate 203, the through hole 612 on the right vertical plate of the moving contact frame 61, the spline hole 613 on the left vertical plate of the moving contact frame 61 and the first flanged bushing 41 embedded in the first flanged bushing through hole 204 of the base vertical plate 203, and then its left end is axially limited by the stop nut 8.

[0115] In the present invention, in a specific implementation, two wire inlet holes 911 are provided on the upper part of the upper end cover 91;

[0116] A cable waterproof connector 912 is installed on each cable entry hole 911;

[0117] In a specific implementation, a step hole 920 is provided at the lower portion of the lower end cover 92;

[0118] The left and right sides of the step hole 920 are respectively arranged correspondingly to an identification sleeve 12 and a guide tube 13.

[0119] In a specific implementation, the front and rear sides of the upper portion of the upper end cover 91 and the front and rear sides of the upper portion of the lower end cover 92 are fixedly connected by a transversely distributed long bolt 10 .

[0120] In a specific implementation, the left and right ends of each long bolt 10 are respectively provided with external threads.

[0121] In the present invention, in a specific implementation, the front and rear sides of the lower part of the upper end cover 91 and the front and rear sides of the lower part of the lower end cover 92 are fixedly connected to the top of the bottom plate 1 through an angle iron 11 respectively.

[0122] In specific implementation, each angle iron 11 is in an "L" shape, and a transversely distributed, triangular reinforcing rib plate 112 is provided in the middle of the longitudinal direction;

[0123] Each angle iron 11 includes a vertical plate and a horizontal plate vertically connected to each other;

[0124] Two angle iron mounting holes 111 spaced apart from each other are respectively provided on the vertical plate and the horizontal plate.

[0125] It should be noted that, for the present invention, the upper parts of the upper end cover 91 and the lower end cover 92 are connected by two long bolts 10, and the lower parts of the upper end cover 91 and the lower end cover 92 are fastened to the base plate 1 by screws through two angle irons 11 respectively.

[0126] In the present invention, in a specific implementation, the identification sleeve 12 is a flange;

[0127] The front and rear ends of the identification sleeve 12 are respectively provided with an identification sleeve mounting hole 121;

[0128] The identification sleeve 12 is provided with an identification sleeve inner hole 122 at the center position;

[0129] The edge of the inner hole 122 of the identification sleeve has two rectangular protruding teeth 1220 distributed at a preset angle;

[0130] It should be noted that, for the present invention, the inner hole 122 of the identification sleeve has a convex tooth with a certain angle (such as a rectangular convex tooth 1220), which can play the role of a lock hole and is used to identify whether a hand crank with a specific tooth opening (i.e., a rectangular tooth groove 1631) is inserted.

[0131] In the present invention, in a specific implementation, the laterally distributed guide tube 13 includes a guide tube body 130;

[0132] The guide tube body 130 is a round tube;

[0133] A flange mounting joint 131 is provided at the left end of the guide tube body 130;

[0134] The right end of the guide tube body 130 is open;

[0135] The right end of the guide tube body 130 is provided with an arc-shaped notch 132 with an open top;

[0136] An arc-shaped limiting groove 133 is formed on the right side wall of the notch 132 to accommodate the flat plate 162 in the middle of the hand crank 16 .

[0137] In a specific implementation, the inner hole 122 of the identification sleeve, the step hole 920 and the guide tube body 130 of the guide tube 13 are located on the same central axis.

[0138] It should be noted that, in the present invention, the identification sleeve 12 is used to identify whether the hand crank 16 of the corresponding model of the switch machine is inserted. If yes, the two rectangular grooves 1631 on the outer side of the left end cylinder of the hand crank circular tube section 163 are allowed to pass through the inner hole 122 of the identification sleeve, and further the hand crank 16 and the linkage shaft 7 are connected. When the hand crank 16 is rotated, the middle section slender axis 1633 of the circular tube section 163 of the hand crank 16 can rotate in the inner hole 122 of the identification sleeve without being restricted by the two rectangular protruding teeth 1220 of the inner hole 122 of the identification sleeve.

[0139] In the present invention, the role of the guide tube 13 specifically includes three aspects. The first is the supporting role: the inner diameter of the guide tube 13 is matched with the outer diameter of the solid cylindrical section 1634 of the connecting section of the circular tube section 163 and the flat plate 162 in the hand crank with a small gap, forming a supporting role when the hand crank linkage shaft is turned to avoid loose movement during the hand crank; the second is the anti-peeping role: the setting of the guide tube makes it impossible to directly observe the convex teeth arrangement of the identification sleeve from the outside, thereby playing an anti-peeping role and avoiding cracking attempts. The third is the guiding role: after adding the guide tube support, the notch 132 of the guide tube 13 plays a guiding role. Only after the hand crank 16 aligns its flat plate 162 with the notch 132, can the rectangular tooth groove 1631 of the hand crank and the two rectangular convex teeth 1220 of the inner hole 122 of the identification sleeve be aligned.

[0140] In specific implementation, a longitudinally distributed locking plate 18 is provided directly behind the limiting groove 133;

[0143] The upper portion of the locking plate 18 has locking plate locking holes 180 distributed laterally.

[0144] It should be noted that the flange surfaces of the identification sleeve 12 and the guide tube 13 are respectively mounted on the left and right sides of the lower end cover 92 by two screws.

[0145] In the present invention, in a specific implementation, the upper and lower sides of the middle part of the guide tube 13 are respectively in contact with a clamping plate 14;

[0146] The two clamping plates 14 are symmetrically distributed up and down, and are both "Ω"-shaped plates;

[0147] Each clamping plate 14 has a clamping plate through hole 141 on both the front and rear sides;

[0148] The middle portion of each clamping plate 14 is a circular arc segment 142;

[0149] The inner diameter of the arc segment 142 is the same as the outer diameter of the guide tube 13 .

[0150] In a specific implementation, the front and rear sides of the two clamping plates 14 are fixedly connected to the base plate 1 via a stud bolt 15 respectively.

[0151] It should be noted that the upper and lower ends of the stud bolt 15 are respectively provided with a threaded section, and a hexagonal stop boss is provided in the middle; the upper and lower clamping plates 14 embrace the guide tube 13 and are fastened to the base plate 1 through the stud bolts 15.

[0152] In the present invention, in a specific implementation, the hand crank 16 includes a circular tube section 163 and a handle section 161 distributed on the left and right;

[0153] The round tube section 163 and the handle section 161 are parallel to each other and connected by a flat plate 162;

[0154] The two ends of the flat plate 162 are respectively vertically connected to the circular tube section 163 and the handle section 161 .

[0155] In specific implementation, the circular tube section 163 is a circular tube with a round outer surface and a square inner surface, and the side walls around the left end 1630 thereof are provided with two rectangular tooth grooves 1631 distributed at a preset angle;

[0156] The interior of the left end 1630 has a square groove 1632 opening to the left;

[0157] The two rectangular tooth grooves 1631 are arranged correspondingly to the two rectangular protruding teeth 1220 on the inner hole 122 of the identification sleeve, and the shapes and sizes thereof are matched accordingly.

[0158] In a specific implementation, the circular tube section 163 is on the right side of the left end 1630 , and is provided with a middle section slender shaft 1633 and a solid cylindrical section 1634 in sequence from left to right.

[0159] It should be noted that, the outer side of the left end cylinder of the circular tube segment 163 is provided with two rectangular tooth grooves 1631 distributed at a preset angle; the inner side of the left end cylinder of the circular tube segment 163 (i.e., the inner side of the left end head 1630) is provided with a square groove 1632; the middle section of the circular tube segment is a middle section slender shaft 1633, the diameter of the middle section slender shaft 1633 is smaller than the diameter of the left end head 1630, and is not restricted by the rectangular protruding teeth 1220 on the inner hole 122 of the identification sleeve of the identification sleeve 12, and the middle section slender shaft 1633 can freely penetrate the inner hole 122 of the identification sleeve; the connecting section between the circular tube segment 163 and the flat plate 162 is a solid cylindrical segment 1634, and the outer diameter of the solid cylindrical segment 1634 is clearance-matched with the inner diameter of the guide tube 13.

[0160] It should be noted that when the circular tube segment 163 passes through the inner hole 122 of the identification sleeve, the two rectangular protruding teeth 1220 on the inner hole 122 of the identification sleeve correspondingly pass through the two rectangular tooth grooves 1631 laterally.

[0161] The spacing angle between the two rectangular tooth grooves 1631 corresponds to the spacing angle between the two rectangular protruding teeth 1220 .

[0162] It should be noted that the rear axial section (ie, the right side portion) of each rectangular tooth socket 1631 becomes thinner.

[0163] In specific implementation, the handle segment 161 includes a handle segment body 160 and a rubber handle cover 1611;

[0164] A rubber handle sleeve 1611 is sleeved on the outside of the handle section body 160;

[0165] A half portion of the handle segment body 160 is fixedly embedded with a plurality of steel balls 1612 by welding.

[0166] In specific implementation, a tablet lock hole 1620 is provided in the middle of the tablet 162;

[0167] When the hand crank 16 is rotated backward so that the flat plate 162 is placed horizontally and longitudinally, the locking plate locking hole 180 on the upper part of the locking plate 18 is located on the right side of the flat plate locking hole 1620 and on the same axis. Therefore, at this time, the position of the hand crank 16 can be locked by a latch or a special lock.

[0168] It should be noted that, for the present invention, from the insertion direction of the hand crank 16 (i.e., insertion from right to left), the hand crank 16 is inserted into the guide tube 13 until the flat plate 162 is aligned with the limiting groove 133 of the guide tube 13, and then the linkage shaft 7 is driven clockwise to rotate the hand crank 16 to a horizontal position. At this time, the flat plate 162 enters the limiting groove 133, and the flat plate lock hole 1620 of the hand crank is aligned with the lock plate lock hole 180, allowing further padlocking at the lock hole.

[0169] In the present invention, in a specific implementation, the exterior of the upper end cover 91 and the lower end cover 92 is covered with a cover plate 17;

[0170] The left and right ends of the bottom surface of the top flat plate of the cover plate 17 are respectively mounted on the top of the upper end cover 91 and the lower end cover 92;

[0171] The lower part of the front and rear support plates of the cover plate 17 is respectively provided with three cover plate foot holes;

[0172] The cover plate 17 is fastened to the base plate 1 by screws.

[0173] To sum up, the technical solution of the present invention can solve the problem in the prior art that the hand-operated tool of the switch machine is missing but not discovered in time, resulting in the inability to deal with emergencies, and solve the problem of safety risks when manually operating a single switch machine in a multi-machine traction turnout.

[0174] To sum up, compared with the prior art, the intelligent management device for the hand-cranked tools of a switch machine provided by the present invention has a scientific structural design and can be used as a daily storage box for the hand-cranked tools of a switch machine, which is convenient for use and can clearly see whether the hand crank handle is missing, thereby facilitating management. It can solve the problem in the prior art that emergency handling cannot be handled due to the failure to timely discover the missing hand-cranked tools (i.e., the hand crank handle) of the switch machine, and has great production practical significance.

[0175] In addition, the device of the present invention has the ability to identify and prevent fraud. An identification sleeve with specific threads is provided in the device. Only hand-cranked tools (i.e., hand crank handles) with matching threads are allowed to pass through the identification hole (i.e., the inner hole of the identification sleeve). This can truly play a role in intelligent management of the hand-cranked tools of the switch machine and avoid the mistaken insertion of hand-cranked tools that do not match the switch machine.

[0176] In addition, in specific applications, by using the device of the present invention in parallel with other warning devices (such as warning lights, alarm bells, etc.), when the hand crank in the device of the present invention is not taken out, the dynamic and static contact groups are in a connected state, which is equivalent to a wire, and the warning device connected in parallel with it is in a short-circuited state and does not work; when the hand crank is taken out, the dynamic and static contact groups are in a disconnected state, so that the warning device can be powered normally and send out warning information.

[0177] See also Fig.19As shown, in a specific embodiment of the present invention, two terminals 524 (for example, the two terminals 524 at positions 1 and 2) connected to the rear ends of any pair of terminal sheet groups symmetrically distributed in the static contact group 52 are respectively connected to the positive terminal and the negative terminal of a warning device 100;

[0178] The positive terminal and the negative terminal of the warning device 100 are also connected to two ends of an external driving power source respectively.

[0179] Therefore, when the moving contact post 622 in the moving contact group 62 is inserted between the two static contacts (i.e., between the left contact sheet 522 and the right contact sheet 523) due to the rotation of the moving contact frame 61 and the linkage shaft 7, the two terminals 524 No. 1 and No. 2 are turned on, which is equivalent to the short circuit of the warning device. It should be noted that, since the resistance is extremely small when the moving and static contacts are connected, which is equivalent to a wire, the current will flow directly through the two terminals 524 at the positions of the static contacts No. 1 and No. 2, thereby bypassing the warning device 100. When the moving and static contacts are disconnected, that is, when the moving contact post 622 in the contact group 62 is no longer inserted between the two static contacts (i.e., between the left contact sheet 522 and the right contact sheet 523), the current flows through the warning device 100 normally.

[0180] In specific implementation, for the warning light, when it lights up, it means that the hand crank is in the removed state, which can alert the on-duty personnel that someone may be manually operating the switch machine outdoors for maintenance, and the switch machine should not be operated electrically at this time, or the hand crank tool has not been returned in time after the maintenance is completed, or the hand crank is lost.

[0181] In addition, the device of the present invention has a compact structure and is easy to install. The mechanical part only needs four screws to be installed on an external installation plane such as the wall in the control room, and the electrical part only needs to be connected in series to the common circuit of the switch motor line of the existing turnout control circuit (to play the role of a switch).

[0182] In specific application, by connecting the device of the present invention in series in the common circuit of the switch machine motor line of the existing turnout control circuit, when the hand crank is put in, the outdoor switch machine control circuit can be turned on (at this time, all the multiple switch machines in the multi-machine traction turnout are powered normally), and when the hand crank is taken out, the outdoor switch machine control circuit can be automatically cut off (the outdoor switch machine control circuit serves as the main power supply circuit for all the multiple switch machines in the multi-machine traction turnout, and the device of the present invention is connected in series on the main power supply line, for example, on the power supply bus), and the power supply of multiple switch machines can be cut off at the same time to protect the safety of the operator. Therefore, the problem of safety risks in the prior art when manually operating a single switch machine in a multi-machine traction turnout can be solved, and power-off protection can be implemented when the switch machine is manually operated, which can effectively ensure personal safety when manually operating the switch machine.

[0183] In the present invention, in specific implementation, based on Fig. 20 The moving contact group 62 and the static contact group 52 shown can connect in series the two terminals 524 (terminals 1 and 2, or terminals 3 and 4, or terminals 5 and 6) connected to the rear ends of any pair of contact plate groups symmetrically distributed on the left and right, to the common circuit of the switch motor line of the existing turnout control circuit, such as the common circuit of the switch motor line of the turnout control circuit recorded in "6502 Electrical Centralized Circuit (Revised Edition)" published by China Railway Publishing House, and of course, it can also be the common circuit of the switch motor line of other turnout control circuits.

[0184] Among them, the common circuit of the switch machine motor line of the existing turnout control circuit is used to control whether the motors of multiple switch machines in the same group of turnouts are powered on. This is its own control function and will not be repeated here.

[0185] In the present invention, in terms of specific implementation, in a specific embodiment, two terminals 524 (for example, the two terminals 524 at positions 1 and 2) connected to the rear ends of any pair of contact sheet groups symmetrically distributed on the left and right in the static contact group 52 are connected in series to the common circuit 200 of the switch motor line of the existing switch control circuit. For example, two terminals obtained by disconnecting a section of the connection line in the common circuit 200 of the switch motor line of the existing switch control circuit are respectively connected to the two terminals 524 connected to the rear ends of any pair of contact sheet groups symmetrically distributed on the left and right in the static contact group 52.

[0186] It should be noted that the device of the present invention is equivalent to a safety switch. When the hand crank is removed from the device, the common circuit of the switch machine motor line of the existing turnout control circuit is disconnected. At this time, the motors of multiple switch machines in the same group of turnsouts cannot be powered.

[0187] Take the existing four-wire turnout control circuit as an example. When the No. 1 and No. 2 (or No. 3 and No. 4, or No. 5 and No. 6) terminals 524 in the static contact group 52 of the device of the present invention are connected in series to the common circuit of the switch motor line of the turnout control circuit, when the common circuit of the switch motor line is disconnected, the motors of multiple switch machines in the same group of turnouts cannot be powered. This is the working characteristic and function of the existing four-wire turnout control circuit, which will not be repeated here.

[0188] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
