Description

Technical Field

[0001] The present invention relates to the technical field of railway track transportation, and in particular to a monitoring device and a switch machine. Background Art

[0002] The state of turnout switching equipment directly affects the safety of trains. With the continuous increase in the density of urban rail traffic, in order to ensure driving safety, the requirements for the operation state of turnout switching equipment are getting higher and higher. Among them, the switch machine, as an important turnout switching equipment, has the characteristics of high switching frequency, frequent application, and great impact on line traffic after equipment failure. It has always been the focus and difficulty of on-site maintenance and repair.

[0003] 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.

[0004] For the switch machine, the automatic switch on it is a mechanism used to reflect the position of the switch, connect and disconnect the motor control circuit and the indication circuit. Its main functions include: 1. Switching of the control circuit: During the switching process of the switch machine, the automatic switch forms two contact changes with its mechanical action. The first change cuts off the original indication circuit to prepare the conditions for the reverse switching starting circuit; the second change cuts off the current starting circuit, stops the motor from rotating, and connects the indication circuit. 2. Responding to the switch position: The automatic switch cooperates with the indicating rod to move. When the switch is in place, the automatic switch controls the inspection column to fall into the notch on the indicating rod. When the gap is kept within a fixed range, it can be considered that the switch is in place and the point rail is in a close fit.

[0005] For the switch machine, the roller on it is a key component of the switch machine, which cooperates with the push plate sleeve, action plate and other components. Under the push of the push plate sleeve, the roller rolls on the action plate. When the roller rolls to a specific position of the action plate, the roller will rise or fall along the slope of the action plate, triggering the contact and disconnection of the dynamic and static contacts of the automatic switch, thereby realizing the change of the circuit.

[0006] Therefore, whether the automatic switches and rollers on the switch machine can operate reliably is directly related to the normal operation of the switch machine, and then to the safe operation of the train.

[0007] However, there is no technology that can reliably monitor the running status of the automatic switch and roller in the switch machine through video. Summary of the invention

[0008] The purpose of the present invention is to provide a monitoring device and a switch machine in view of the technical defects in the prior art.

[0009] To this end, the present invention provides a monitoring device, which includes a switch machine modified cover, a video acquisition component and a first fastener;

[0012] Two slideway devices symmetrically distributed on the left and right are arranged on the inner side of the switch machine cover body;

[0013] Video acquisition components are arranged in the two chute devices;

[0014] A video acquisition component is used to acquire video images of an automatic switch and a roller arranged in a lower housing of a switch machine to be monitored;

[0015] The bottom rear end of the modified switch machine cover is hinged to the top rear end of the original switch machine lower shell of the switch machine;

[0016] When the bottom of the switch machine modified cover contacts the top of the switch machine lower shell, the video acquisition assembly is located above the automatic opener and the roller;

[0017] Two slide slot devices are respectively connected to two ends of the video acquisition component through first fasteners;

[0018] Each chute device includes a chute top plate and a chute bottom plate which are spaced apart from each other.

[0019] The two chute devices are provided with chute side plates on opposite sides;

[0020] The upper and lower ends of the chute side plates are connected to the chute top plate and the chute bottom plate respectively;

[0021] For each chute device, a guide chute for placing one end of the video acquisition component is formed between the chute side plate, the chute top plate and the chute bottom plate.

[0022] In addition, the present invention also provides a switch machine, which includes a monitoring device as claimed in any one of claims 1 to 4, and a switch machine lower housing;

[0023] The lower housing of the switch machine is a hollow housing with an opening at the top;

[0024] An automatic opener and closer and two rollers are provided in the lower housing of the switch machine;

[0025] The top of the lower casing of the switch machine is sealed and connected to the bottom of the modified cover of the switch machine;

[0026] The video acquisition component is used to acquire video images of the automatic switch and the roller arranged in the lower shell of the switch machine.

[0028] Compared with the prior art, the present invention can monitor the automatic switch and roller in the switch machine, which can help to timely discover and reflect the following problems:

[0029] 1. Switch position status: By monitoring the on and off of the contacts of the automatic switch, the switch opening position and the closeness of the point rail can be accurately determined to ensure the correct direction of the train.

[0030] 2. Equipment failure: If the automatic switch or roller fails (such as poor contact of the automatic switch, roller jamming, etc.), the monitoring device of the present invention can transmit the video signal of the automatic switch or roller failure to the indoor monitoring host, and the monitoring host will issue an alarm in time to remind the maintenance personnel to carry out maintenance to avoid affecting the train operation.

[0031] 3. Operation efficiency and safety: The present invention monitors the automatic switch and roller, which is conducive to further evaluating the operation efficiency and safety of the switch machine, and provides an important basis for the optimization and maintenance of the railway system.

[0032] 4. Video monitoring of the automatic switch and roller in the switch machine can better assist in monitoring the turnout status and the switch machine movement status, help predict faults and handle them in advance, and reduce the occurrence of faults. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The bottom rear end of the modified switch machine cover 1 is hinged (i.e., rotatably connected) to the top rear end of the original switch machine lower housing 4 of the switch machine;

[0060] When the bottom of the switch machine reforming cover 1 contacts the top of the switch machine lower shell 4 , the video acquisition assembly 2 is located above the automatic shutter 5 and the roller 6 .

[0061] In the present invention, the bottom surface of the modified cover 1 of the switch machine is in contact with the top surface of the video acquisition component 2 .

[0062] In the present invention, see Figures 3 to 5 , a switch machine modified cover 1, including a switch machine cover body 101 and a chute device 102;

[0063] Two chute devices 102 are arranged on the inner side of the switch machine cover body 101 and are symmetrically distributed on the left and right sides;

[0064] The two chute devices 102 are provided with a video acquisition component 2;

[0065] The two slide slot devices 102 are connected to two ends of the video acquisition component 2 through the first fasteners 3 respectively.

[0066] In specific implementation, each chute device 102 includes a chute top plate 1020 and a chute bottom plate 1021 which are spaced apart from each other.

[0075] Furthermore, on the chute top plate 1020 of each chute device 102, four first through holes 10201 are vertically penetrated and distributed at equal intervals in the longitudinal direction;

[0076] The four first through holes 10201 are through holes for welding, which are used to facilitate the staff to spot weld the welding block 1023 on the inner wall of the top plate 1020 of the chute device 102;

[0077] Furthermore, two second through holes 10202 are vertically arranged on the top plate 1020 of each chute device 102 and are spaced apart from each other.

[0078] The welding block 1023 is vertically penetrated by two third threaded connection through holes which are spaced apart longitudinally at positions corresponding to the two second through holes 10202;

[0079] The third threaded connection through hole is used to connect to the video acquisition component 2 through the first fastener 3.

[0080] Furthermore, the slide bottom plate 1021 of each slide device 102 is vertically penetrated by two fourth through holes 10211 which are longitudinally spaced apart at positions corresponding to the two second through holes 10202 and the two third threaded through holes on the welding block 1023;

[0081] Among them, the diameter of the fourth through hole 10211 is smaller than the diameter of the head of the first fastener 3 (that is, the nut of the first bolt); such a design can prevent the first fastener 3 located on the inner side of the bottom plate 1021 of the first fastener 3 slide groove from falling outward through the through hole.

[0082] Furthermore, the diameter of the fourth through hole 10211 is larger than the diameter of the hexagonal wrench used to tighten the first fastener 3;

[0084] The first fastener 3 passes through the countersunk mounting hole 20101 on the box body 201 and is threadedly fixedly connected to the third threaded connection through hole on the welding block 1023 of the slide groove device 102 .

[0085] Furthermore, a vertically distributed limiting hole 10221 is provided at the middle position of the chute side plate 1022 of each chute device 102, for limiting the video acquisition component 2;

[0086] Furthermore, the shape of the limiting hole 10221 is an oblong (ie, an ellipse).

[0087] In the present invention, see Figures 6 to 9 , the video acquisition component 2 includes a box body 201, a first camera module 202 and a second camera module 203;

[0088] The box body 201 includes a box body bottom plate 2013 and a box body upper side plate 2015;

[0089] The top of the box body bottom plate 2013 is surrounded by a box body upper side plate 2015 protruding upwards;

[0090] It should be noted that the middle position at the top of the box body 201 is an internal hollow structure (i.e., an inner groove), that is, the upper side plate 2015 of the box body and the bottom plate 2013 of the box body form an inwardly concave groove structure, wherein the bottom plate 2013 of the box body is the bottom of the groove, and the upper side plate 2015 of the box body serves as the side walls around the groove.

[0091] Two first cameras are arranged at the rear side of the bottom of the box body bottom plate 213 and are symmetrically distributed on the left and right sides;

[0092] The two first cameras together form a first camera module 202;

[0099] The second camera module 203 is used to photograph the automatic switches on both sides of the switch machine.

[0100] In specific implementation, two longitudinally distributed countersunk mounting holes 20101 are respectively provided at the left and right ends of the box body 201;

[0101] The countersunk mounting hole 20101 is used to connect with the welding block 1023 (specifically, the third threaded connection through hole on the welding block 1023) on the slide slot device 102 of the switch machine modified cover 1 through the first fastener 3.

[0102] In specific implementation, both sides of the rear end of the box body bottom plate 2013 are symmetrically provided with a first vertical circular through hole and a first vertical rectangular hole, and the first vertical circular through hole and the first vertical rectangular hole are horizontally spaced and distributed left and right;

For the present invention, the light board 204 is designed with LEDs distributed in an L shape horizontally and spaced from left to right, which can provide multi-angle light supplement, reduce the shadow area of ​​the shooting picture, and make the photographed object clearer and three-dimensional. In specific implementation, the design requirements of the vertical L-shaped hole are: the L-shaped hole should expose the LED lights distributed in an L shape on the light board 204, and the LED should be placed in the center of the hole to ensure that the light is evenly distributed.

[0108] Furthermore, at the rear end of the box body bottom plate 2013, first rivet studs 2010 are respectively provided at the left front corner and the right rear corner of each first vertical circular through hole;

[0109] A first camera module 202 is disposed on the two first riveting studs 2010;

[0110] At the front end of the box body bottom plate 2013, second rivet studs 2011 are respectively provided at the left front corner and the right rear corner of each second vertical circular through hole;

[0111] A second camera module 203 is disposed on the two second riveting studs 2011;

[0112] Furthermore, the first riveting stud 2010 is connected to the first camera module 202 by a second fastener 210 (eg, a second bolt);

[0113] The second riveting stud 2011 is connected to the second camera module 203 by using a third fastener 211 (such as a third bolt);

[0114] In specific implementation, four third pressure riveting studs 2012 are arranged at intervals in the middle of the bottom plate 2013 of the box body;

[0118] In specific implementation, a light board 204 is provided in the middle of the bottom surface of the box body bottom plate 2013;

[0119] The light board 204 is provided with an LED (light emitting diode) 2040 for supplementing the camera module with light, ensuring that the light board 204 irradiates light onto the automatic switch and roller, so that the camera module can clearly and accurately capture video images.

[0120] It should be noted that in the present invention, the lamp board 204 is an integral piece, and four mounting holes are arranged on the lamp board. The shape formed by the lines connecting the center points of the mounting holes is a T shape, which corresponds to the four third riveted studs 2012 on the box body, and is connected to the third riveted studs on the box body using a fourth fastener.

[0121] In specific implementation, the left end portion of the upper side plate 2015 of the box body is the left side plate 2014 of the box body;

[0122] A transversely distributed mounting blind hole is provided in the longitudinal middle of the left side plate 2014 of the box body;

[0123] A spring plunger 205 is arranged in the installation blind hole;

[0124] One end of the spring plunger 205 is used to be inserted into the limiting hole 10221 on the slide slot device 102 of the switch machine modified cover 1.

[0125] Furthermore, the spring plunger 205 and the mounting blind hole adopt an interference fit, so that the spring plunger 205 is not easy to fall off from the box body 201;

[0126] In specific implementation, a threaded hole is provided at the right end of the upper side plate 2015 of the box body for connecting the waterproof connector 213;

[0127] The cables of the video acquisition component 2 (specifically, the cables attached to the first camera module 202 and the second camera module 203, which have current conduction and data transmission functions) pass through the waterproof connector 213 and are connected to the video data acquisition end of the video acquisition device in the machine (such as the acquisition extension). The acquisition extension uploads the acquired video data (video signal) to the indoor monitoring host, thereby realizing the transmission of the video signal, thereby realizing remote video monitoring of the automatic switch and roller.

[0128] It should be noted that the in-machine video acquisition equipment is a mature and widely used device with existing technology. For example, the JZCD·ZC acquisition extension produced by Tianjin Railway Signal Co., Ltd. can be used to receive and process various sensor data such as video signals and analog signals. The acquisition extension uploads the processed data to the indoor monitoring host.

[0129] In specific implementation, a top cover 207 is provided on the top surface of the box body 201;

[0130] A sealing ring 206 is provided between the box body 201 (specifically, the inner edges of the upper side plate 2015 of the box body, i.e., the top edges of the groove) and the top cover 207, so that the entire video acquisition assembly is waterproof and dustproof;

[0131] Four box body threaded holes 20102 are vertically penetrated at the front and rear ends of the box body 201 and are evenly spaced laterally;

[0132] The top cover 207 is provided with a top cover through hole at a position corresponding to each box body threaded hole 20102;

[0133] The box body 201 is fixedly connected to the top cover 207 via a second fastener 210 (such as a second bolt);

[0134] After the second fastener 210 (eg, a second bolt) passes through the through hole of the top cover, it is threadedly fixedly connected to a corresponding threaded hole 20102 of the box body.

[0135] In specific implementation, a frosted panel is provided (for example, pasted) on the bottom surface of the box body bottom plate 2013;

[0136] The frosted panel is located directly below the light panel 204;

[0137] It should be noted that the frosted panel is used to avoid metal reflection, so as to soften the LED light of the light board 204 and improve the lighting quality of the light board;

[0138] A transparent panel is arranged (for example, pasted) on the bottom surface of the frosted panel;

[0139] It should be noted that the transparent panel has high impact resistance and is used to protect the camera.

[0140] It should be noted that the transparent panel covers the bottom surfaces of the cameras of the first camera module 202 and the second camera module 203, as well as the bottom surface of the frosted panel; the frosted panel and the positions corresponding to the cameras of the first camera module 202 and the second camera module 203 have reserved circular, transparent area parts (i.e., non-frosted parts), which will not affect the normal shooting of the cameras.

[0141] It should be noted that the frosted panel covers the bottom surface of the box body bottom plate 2013 and has a through hole reserved for the first fastener 3 to pass through.

[0142] In the present invention, in specific implementation, the present invention has an anti-drop design for the first fastener 3, which is specifically described as follows;

[0143] In order to ensure that the first fastener will not fall into the switch machine after being loosened due to vibration or other factors, thereby affecting the operation of the switch machine, the present invention designs an anti-slip structure: specifically, the slideway bottom plate 1021 of each slideway device 102 is provided with two fourth through holes 10211 at positions corresponding to the two third threaded through holes (for screwing in the first fastener 3) on the welding block 1023;

[0144] Among them, the diameter of the fourth through hole 10211 is smaller than the head diameter of the first fastener 3; such a design can prevent the first fastener 3 located on the inner side of the bottom plate 1021 of the first fastener 3 slide groove from falling outward through the through hole.

[0145] After the first fastener 3 passes through the countersunk mounting hole 20101 on the box body 201 , it is fixedly connected to the third threaded connection through hole on the welding block 1023 of the slide groove device 102 .

[0146] It should be noted that the fourth through hole 10211 of the chute bottom plate 1021 is used to allow a worker to insert a hexagonal wrench through its inner cavity into the chute device 102 to tighten the first fastener 3, while preventing the first fastener 3 from falling off.

[0147] The diameter of the fourth through hole 10211 is larger than the diameter of the hexagonal wrench used to fasten the first fastener 3;

[0148] It should be noted that when the video acquisition component 2 and the first fastener 3 slide into the chute device 102 together, the bottom surface of the video acquisition component 2 is close to the bottom inner wall of the chute device 102, and the tail of the first fastener 3 has a gap from the guide chute 1025. During the sliding process, the first fastener 3 and the chute device 102 will not interfere with each other, and the video acquisition component 2 can slide smoothly into the chute device 102. Then, the staff inserts the hexagonal wrench through the fourth through hole 10211 of the chute bottom plate 1021, and uses the hexagonal wrench to fasten the first fastener 3 to the third threaded connection through hole on the welding block 1023.

[0149] When the first fastener 3 is loosened from the video acquisition component 2 to the bottom inner wall of the slide slot device 102 due to vibration or other factors, since the diameter of the through hole on the bottom of the slide slot device 102 (i.e., the fourth through hole 10211) at the corresponding position of the first fastener 3 is smaller than the head diameter of the first fastener 3, and a small amount of the tail of the first fastener 3 remains in the mounting hole (i.e., the countersunk mounting hole 20101) of the video acquisition component 2, the first fastener 3 will be stuck in the mounting hole (i.e., the countersunk mounting hole 20101) of the video acquisition component 2 after being loosened, and will not fall from the slide slot device 102 into the interior of the switch machine, thereby avoiding affecting the normal operation of the switch machine.

[0150] In the present invention, in specific implementation, the monitoring device of the present invention is designed with a limit, which is specifically described as follows:

[0151] When the four first fasteners 3 are loosened from the video acquisition assembly due to vibration or other factors, a limiting structure is designed for the video acquisition assembly 2 to prevent the video acquisition assembly 2 from sliding out in the opposite direction of the pushing direction.

[0152] The design of the limiting structure is as follows: a spring plunger 205 is installed in the middle of the left side plate of the box body of the video acquisition component 2, and the spring pin head on the spring plunger 205 can be elastically retracted. When the video acquisition component 2 slides into the guide slide groove 1025, the spring plunger 205 is pressed to compress the spring pin head to be flush with the left side plate 2014 of the box body of the video acquisition component 2, so that the video acquisition component 2 can smoothly slide into the guide slide groove 1025; when the spring pin head slides to the position of the limiting hole on the side wall of the slide groove device 102, the spring pin head pops into and penetrates the limiting hole on the side wall of the slide groove device 102, so that the video acquisition component 2 is limited in the sliding direction, avoiding loosening and sliding out of the slide groove device 102, thereby avoiding affecting the normal operation of the switch machine.

[0153] In a specific implementation, the installation blind hole of the left side plate 2014 of the box body of the video acquisition component 2 and the spring plunger 205 adopt an interference fit, so that the spring plunger 205 is not easy to loosen from the box body of the video acquisition component 2.

[0154] In summary, after the device of the present invention adopts the anti-drop design and the limit design, the video monitoring component and the first fastener will not fall off and fall into the interior of the switch machine, thereby avoiding affecting the operation of the switch machine and having higher safety.

[0155] After inspection, the present invention provides a video monitoring device for automatic switches and rollers in switch machines with high reliability, strong anti-interference ability and high safety, which can be reliably applied to switch machine monitoring equipment in the railway industry.

[0156] Based on the monitoring device provided by the present invention, the present invention further provides a switch machine, which includes the monitoring device described above, and a switch machine lower housing 4;

[0157] The switch machine lower housing 4 is a hollow housing with an open top;

[0158] An automatic switch 5 and two rollers 6 are arranged in the lower housing 4 of the switch machine;

[0159] The top of the switch machine lower housing 4 is sealed and connected to the bottom of the switch machine modified cover 1;

[0160] The video acquisition component 2 in the monitoring device is used to acquire video images of the automatic switch 5 and the roller 6 arranged in the lower housing 4 of the switch machine.

[0161] It should be noted that the two rollers 6 are used to roll on the transversely distributed action plates 7 arranged in the lower housing 4 of the switch machine. This is a conventional structural design of the existing switch machine and will not be described in detail here.

[0162] In terms of specific implementation, the various component structures installed inside and outside the lower housing of the switch machine are conventional supporting structures in the switch machine with mature existing technology, and will not be described in detail here.

[0163] In terms of specific implementation, it should be noted that the switch machine of the present invention can be basically the same as the ZDJ9 switch machine produced by Tianjin Railway Signal Co., Ltd. The difference lies in: the structure of the switch machine cover is improved, a specially designed switch machine modified cover 1, and a completely new video acquisition component 2 is designed.

[0164] In specific implementation, the bottom rear side of the switch machine reforming cover 1 is hinged to the top rear side of the switch machine lower housing 4 (ie, rotatably connected).

[0165] In order to more clearly understand the technical solution of the present invention, the working process of the present invention is described below.

[0166] First, see Fig.10As shown, place the modified switch machine cover 1 upward, insert the first fastener 3 into the countersunk holes on the left and right sides of the video monitoring component 2, and press the spring plunger 205 to compress it until it is flush with the left side plate 2014 of the video acquisition component box body;

[0167] Then, the video monitoring component 2 and the first fastener 3 are pushed into the slide slot device 102 together. When the video acquisition component 2 slides into the slide slot device 102 (sliding direction, such as Fig.10 As shown in the direction A in the figure, the box bottom plate 2013 of the video acquisition component 2 is made close to the bottom inner wall of the slide groove device 102, and there is a gap between the tail of the first fastener 3 and the guide slide groove. During the sliding process, the first fastener 3 and the slide groove device 102 will not interfere with each other, and the video acquisition component 2 can slide smoothly into the slide groove device 102.

[0168] Then, when the four first fasteners 3 all slide to the corresponding threaded holes on the welding block 1023 of the slide groove device, use an Allen wrench to pass through the through hole on the bottom plate 1021 of the slide groove device to fasten the first fastener 3 into the threaded hole on the welding block 1023 of the slide groove device 102 (the diameter of the Allen wrench is smaller than the diameter of the through hole on the bottom plate of the slide groove device, and the Allen wrench can pass through the through hole on the bottom plate of the slide groove to fasten the first fastener).

[0169] Compared with the prior art, the monitoring device and switch machine provided by the present invention have the following beneficial effects:

[0170] 1. The present invention is a video monitoring device for the automatic switch and roller in the ZDJ9 type switch machine.

[0173] 4. The present invention adopts a sealed design to be waterproof and dustproof;

[0174] It should be noted that, for the present invention, on the one hand, in the video monitoring component 2, a sealing gasket (i.e., a sealing ring) is provided between the top surface of the box body and the top cover, which can prevent water and dust from entering the interior of the video monitoring component 2 from the top surface of the box body; on the other hand, a frosted panel and a transparent panel are attached to the bottom surface of the box body, and the light holes and lens holes (such as the first vertical circular through hole, the first vertical rectangular hole, the vertical L-shaped hole and the second vertical circular through hole, etc.) on the bottom surface of the box body are all sealed to prevent water and dust from entering the interior of the video monitoring component 2 from the light holes and lens holes on the bottom surface of the box body, thereby achieving good waterproof and dustproof functions.

[0175] 5. The present invention is installed inside the switch machine cover, and there is no need to open additional installation holes on the switch machine, which does not affect the protection level of the switch machine;

[0176] 6. For the present invention, the first camera module 202 and the second camera module 203 are preferably analog cameras, which have higher data transmission reliability and real-time performance than digital cameras in outdoor environments, bad weather, high temperature environments, and motor interference;

[0177] For example, in a specific implementation, the first camera module may adopt a camera model JQ 1·CT·ZM-6 produced by Tianjin Railway Signal Co., Ltd., and the second camera module may adopt a camera model JQ 1·CT·ZM-6A produced by Tianjin Railway Signal Co., Ltd.

[0178] 7. The present invention is easy to disassemble, which is convenient for the staff to perform daily maintenance and repair of the switch machine.

[0179] 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.
