Description

Technical Field

[0001] This utility model relates to the field of railway rail transit technology, and in particular to a monitoring device and a switch machine. Background Technology

[0002] The condition of turnout switching equipment directly affects train safety. With the continuous increase in urban rail transit density, the requirements for the operational status of turnout switching equipment are becoming increasingly stringent to ensure train safety. Among these, the switch machine, as a crucial turnout switching device, is characterized by high switching frequency, frequent application, and significant impact on track operation after equipment failure, making it a key focus and challenge for on-site maintenance and repair.

[0003] A switch machine is an important signaling infrastructure used to reliably change the position of a turnout, change the direction of the turnout, lock the turnout switch rail, and reflect the position of the turnout. It can effectively ensure traffic safety, improve transportation efficiency, and reduce the labor intensity of traffic operators.

[0004] For a switch machine, the automatic switch is the mechanism used to reflect the switch position and connect and disconnect the motor control circuit and the indication circuit. Its main functions include: 1. Switching the control circuit: During the switching process of the switch machine, the automatic switch causes two contact changes through its mechanical action. The first change cuts off the original indication circuit, preparing the conditions for the reverse switching start circuit; the second change cuts off the current start circuit, stopping the motor and connecting the indication circuit. 2. Reflecting the switch position: The automatic switch works in conjunction with the indication rod. When the switch is in position, the automatic switch controls the inspection pin to fall into the notch on the indication rod. When the gap between the notches is maintained within a fixed range, it can be considered that the switch is in position and the switch rail is in a tight contact state.

[0005] For a switch machine, the rollers are a key component, working in conjunction with the push plate sleeve, the operating plate, and other parts. Driven by the push plate sleeve, the rollers roll on the operating plate. When the rollers reach a specific position on the operating plate, they rise or fall along the ramp, triggering the contact and disconnection of the moving and stationary contacts of the automatic switch, thus achieving the circuit change.

[0006] Therefore, the reliable operation of the automatic gate opener and roller on the switch machine is directly related to the normal operation of the switch machine, and thus to the safety of train operation.

[0007] However, there is currently no technology that can reliably monitor the operating status of the automatic switches and rollers inside the switch machine via video. Utility Model Content

[0008] The purpose of this invention is to address the technical deficiencies of existing technologies by providing a monitoring device and a switch machine.

[0009] Therefore, this utility model provides a monitoring device, which includes a modified switch machine cover, a video acquisition component, and a first fastener;

[0010] The modified cover of the switch machine is connected to the video acquisition component via a first fastener;

[0011] A modified switch machine cover, comprising the switch machine cover body and a chute device;

[0012] On the inner side of the main body of the switch machine cover, two symmetrically distributed sliding groove devices are provided;

[0013] Video capture components are installed inside the two sliding chute devices;

[0014] The video acquisition component is used to acquire video images of the automatic opening and closing devices and rollers installed inside the lower housing of the switch machine that needs 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 casing;

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

[0017] Two sliding groove devices are respectively connected to both ends of the video acquisition component via the first fastener;

[0018] Each chute assembly includes a chute top plate and a chute bottom plate that are spaced apart vertically;

[0019] Two chute devices are located on opposite sides, with chute side plates provided on one side;

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

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

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

[0023] The lower casing of the switch machine is a hollow casing with an open top;

[0024] Inside the lower housing of the switch machine, there is an automatic opening and closing device and two rollers;

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

[0026] The video acquisition component is used to acquire video images of the automatic opening and closing devices and rollers installed inside the lower housing of the switch machine.

[0027] As can be seen from the technical solution provided by this utility model above, compared with the prior art, this utility model provides a monitoring device and a switch machine with a scientific structure design and high reliability. It can reliably monitor the operating status of the automatic opening and closing device and rollers inside the switch machine via video. This helps the staff to make predictions and handle the faults of the switch machine in advance based on the video images, thereby reducing the occurrence of faults. It also provides convenient conditions for on-site personnel to maintain and repair the turnout switching equipment, and has significant practical significance.

[0028] Compared with existing technologies, by applying this invention, the automatic opening and closing devices and rollers inside the switch machine can be monitored, which helps to promptly detect and report the following problems:

[0029] 1. Turnout position status: By monitoring the open and closed contacts of the automatic switch, the open position of the turnout and the tightness of the switch rail can be accurately determined, ensuring the correct direction of train travel.

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

[0031] 3. Operational efficiency and safety: By monitoring the automatic opening and closing device and rollers, this utility model helps to further evaluate the operational efficiency and safety of the switch machine, providing an important basis for the optimization and maintenance of the railway system.

[0032] 4. By video monitoring the automatic switches and rollers inside the switch machine, the status monitoring of the turnout and the movement status of the switch machine can be effectively achieved, which helps to predict and handle faults in advance and reduce the occurrence of faults.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0056] See Figures 1 to 10 This utility model provides a monitoring device, which is a video monitoring device for the automatic opening and closing device and rollers inside a switch machine. The device includes: a modified switch machine cover 1, a video acquisition component 2, and a first fastener 3 (e.g., a first bolt with an internal hexagonal hole on the nut).

[0057] The modified switch machine cover 1 is connected to the video acquisition component 2 via the first fastener 3;

[0058] The video acquisition component 2 is used to acquire video images of the automatic opening and closing device 5 and roller 6 installed inside the lower housing 4 of the switch machine that needs to be monitored.

[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.

[0060] When the bottom of the modified switch cover 1 contacts the top of the lower housing 4 of the switch, the video acquisition component 2 is located above the automatic opener / closer 5 and the roller 6.

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

[0062] In this utility model, see Figures 3 to 5 The modified switch machine cover 1 includes a switch machine cover body 101 and a chute device 102;

[0063] On the inner side of the main body 101 of the switch machine cover, two sliding groove devices 102 are provided, which are symmetrically distributed on the left and right sides.

[0064] Video acquisition components 2 are installed inside the two sliding chute devices 102;

[0065] Two sliding groove devices 102 are respectively connected to both ends of the video acquisition component 2 via the first fastener 3.

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

[0067] Two sliding chute devices 102 are provided with sliding chute side plates 1022 on one side of opposite sides;

[0068] The upper and lower ends of the slide side plate 1022 are connected to the slide top plate 1020 and the slide bottom plate 1021, respectively.

[0069] For each chute device 102, a guide chute 1025 is formed between the chute side plate 1022, the chute top plate 1020 and the chute bottom plate 1021 for inserting one end of the video acquisition component 2.

[0070] Furthermore, the front openings of the guide grooves 1025 of the two chute devices 102;

[0071] The guide grooves on the two chute devices 102 have openings on opposite sides;

[0072] Each chute device 102 has a welded block 1023 installed on the inner wall of the chute top plate 1020;

[0073] The welding block 1023 is connected to the video acquisition component 2 via the first fastener 3.

[0074] Furthermore, the top plate 1020, bottom plate 1021, and side plate 1022 of the chute are integrally formed.

[0075] Furthermore, each chute device 102 has four longitudinally spaced first through holes 10201 vertically through its top plate 1020.

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

[0077] Furthermore, each chute device 102 has two longitudinally spaced second through holes 10202 vertically through its top plate 1020.

[0078] The welding block 1023 has two longitudinally spaced third threaded connection through holes vertically through it 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 via the first fastener 3.

[0080] Furthermore, in each chute device 102, the chute bottom plate 1021 is provided with two longitudinally spaced fourth through holes 10211 at positions corresponding to the two second through holes 10202 and the two third threaded connection through holes on the welding block 1023.

[0081] The diameter of the fourth through hole 10211 is smaller than the diameter of the head of the first fastener 3 (i.e. the nut of the first bolt). This design can prevent the first fastener 3, located inside the slide base plate 1021 of the first fastener 3, from falling outward through the through hole.

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

[0083] The fourth through hole 10211 of the slide base plate 1021 is used to allow the worker to insert an Allen wrench into the slide device 102 through its inner cavity to tighten the first fastener 3, while also preventing the first fastener 3 from falling outward.

[0084] The first fastener 3 passes through the countersunk mounting hole 20101 on the housing 201 and is threadedly fixed to the third threaded connection through hole on the welding block 1023 of the sliding device 102.

[0085] Furthermore, each chute device 102 has vertically distributed limiting holes 10221 at the middle position of the chute side plate 1022 for limiting the video acquisition component 2.

[0086] Furthermore, the limiting hole 10221 is oblong (i.e. elliptical).

[0087] In this utility model, see Figures 6 to 9 The video acquisition component 2 includes a housing 201, a first camera module 202, and a second camera module 203.

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

[0089] The top perimeter of the box bottom plate 2013 is provided with an upper side plate 2015 that protrudes upward and surrounds the box.

[0090] It should be noted that the top center of the box 201 has an internal hollow structure (i.e., an inner groove). In other words, the upper side plate 2015 and the bottom plate 2013 of the box form an inner groove structure, where the bottom plate 2013 is the bottom of the groove and the upper side plate 2015 serves as the four sides of the groove.

[0091] Two first cameras are symmetrically distributed on the bottom rear side of the box base plate 2013;

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

[0093] When the bottom of the modified switch cover 1 contacts the top of the lower housing 4 of the switch, the two first cameras are positioned directly above the action plate 7 set by the original two rollers 6 on the switch (the rollers 6 are used to roll on the action plate 7).

[0094] Action board 7 is horizontally distributed;

[0095] Two second cameras are symmetrically distributed on the bottom front side of the box base plate 2013;

[0096] The two second cameras together form the second camera module 203;

[0097] When the bottom of the modified switch cover 1 comes into contact with the top of the lower housing 4 of the switch, two second cameras are positioned directly above the original automatic opening and closing device 5 on the switch that needs to be monitored.

[0098] It should be noted that the first camera module 202 is used to photograph the rollers on both sides inside the switch machine;

[0099] The second camera module 203 is used to photograph the automatic opening and closing devices on both sides inside the switch machine.

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

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

[0102] In terms of specific implementation, on both sides of the rear end of the box base plate 2013, there is a first vertical circular through hole and a first vertical rectangular hole respectively, which are symmetrically provided on the left and right sides. The first vertical circular through hole and the first vertical rectangular hole are horizontally spaced on the left and right.

[0103] The first vertical circular through hole is used to house the first camera of the first camera module 202;

[0104] The first vertical rectangular hole is used to expose the lamp panel 204;

[0105] On both sides of the front end of the box bottom plate 2013, there is a second vertical circular through hole and a vertical L-shaped hole respectively. The second vertical circular through hole and the vertical L-shaped hole are horizontally spaced to the left and right.

[0106] The second vertical circular through hole is used to house the second camera of the second camera module 203;

[0107] It should be noted that the vertical L-shaped hole serves to expose the L-shaped LEDs on the light panel 204, providing supplementary lighting for the camera module. In this invention, the light panel 204 is designed with L-shaped LEDs spaced horizontally to provide multi-angle lighting, reducing shadow areas in the captured image and making the subject clearer and more three-dimensional. Specifically, the design requirements for the vertical L-shaped hole are: the L-shaped hole must expose the L-shaped LEDs on the light panel 204, and the LEDs should be centered within the hole to ensure uniform light distribution.

[0108] Furthermore, at the rear end of the box bottom plate 2013, a first press-fit stud 2010 is provided at the left front corner and right rear corner of each first vertical circular through hole;

[0109] A first camera module 202 is provided on the two first press-fit studs 2010;

[0110] At the front end of the box base plate 2013, a second press-fit stud 2011 is provided at the left front corner and right rear corner of each second vertical circular through hole;

[0111] A second camera module 203 is mounted on two second press-fit studs 2011;

[0112] Furthermore, the first press-fit stud 2010 is connected to the first camera module 202 using a second fastener 210 (e.g., a second bolt);

[0113] The second press-fit stud 2011 is connected to the second camera module 203 by a third fastener 211 (e.g., a third bolt);

[0114] In terms of specific implementation, four spaced third press-fit studs 2012 are provided in the middle of the bottom plate 2013 of the box body;

[0115] The center points of the four third press-fit studs 2012 are connected to form a T-shape.

[0116] A light panel 204 is installed on the third press-fit stud 2012;

[0117] The third press-fit stud 2012 is connected to the lamp panel 204 using the fourth fastener 212 (e.g., the fourth bolt);

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

[0119] LEDs (light-emitting diodes) 2040 are installed on the light board 204 to provide supplementary lighting for the camera module, ensuring that the light board 204 illuminates the automatic switch machine opener and rollers, so that the camera module can clearly and accurately capture video images.

[0120] It should be noted that in this utility model, the lamp plate 204 is a whole, and the lamp plate is provided with four mounting holes. The shape formed by connecting the center points of the mounting holes is T-shaped, which corresponds to the four third press-fit studs 2012 on the box body. The fourth fastener is used to connect with the third press-fit studs on the box body.

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

[0122] The left side panel 2014 of the box body has horizontally distributed blind mounting holes in the longitudinal center.

[0123] A spring plunger 205 is installed inside the blind mounting hole;

[0124] One end of the spring plunger 205 is used to correspond to the limiting hole 10221 on the sliding groove device 102 of the switch machine modified cover 1.

[0125] Furthermore, the spring plunger 205 is interference-fitted with the mounting blind hole, making it difficult for the spring plunger 205 to fall off the housing 201;

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

[0127] The video acquisition component 2 has a cable (specifically, the cable built into the first camera module 202 and the second camera module 203, which has current conduction and data transmission functions) that passes through the waterproof connector 213 and connects to the video data acquisition end of the in-machine video acquisition device (e.g., the acquisition sub-unit). The acquisition sub-unit uploads the acquired video data (video signal) to the indoor monitoring host, thereby realizing the transmission of video signal, which enables remote video monitoring of the switch machine's automatic opening and closing device and rollers.

[0128] It should be noted that the in-machine video acquisition equipment is a mature and widely used technology. For example, the JZCD·ZC type acquisition unit 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 unit then uploads the processed data to the indoor monitoring host.

[0129] In practice, the top surface of the box 201 is provided with a top cover 207;

[0130] A sealing ring 206 is provided between the housing 201 (specifically, the inner periphery of the upper side panel 2015 of the housing, i.e., the top periphery of the groove mentioned above) and the top cover 207, thereby making the entire video acquisition assembly waterproof and dustproof.

[0131] Four horizontally spaced threaded holes 20102 are respectively provided vertically through the front and rear ends of the box body 201.

[0132] The top cover 207 has a top cover through hole at a position corresponding to each box thread hole 20102;

[0133] The housing 201 is fixedly connected to the top cover 207 by a second fastener 210 (e.g., a second bolt);

[0134] The second fastener 210 (e.g., the second bolt) passes through the top cover through hole and is threadedly fixed to a corresponding box threaded hole 20102.

[0135] In terms of specific implementation, the bottom surface of the box base plate 2013 is provided with (e.g., pasted) a frosted panel;

[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 metallic reflection, making the LED light of the 204 light panel softer and improving the lighting quality of the light panel.

[0138] The bottom surface of the frosted panel has a transparent panel attached (e.g., pasted on).

[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 surface 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 has a circular, transparent area (i.e., the non-frosted part) reserved at the position corresponding to the cameras of the first camera module 202 and the second camera module 203, 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 base plate 2013 and has a through hole for the first fastener 3 to pass through.

[0142] In this utility model, specifically, the first fastener 3 is designed to prevent detachment, as detailed below;

[0143] To ensure that the first fastener does not fall into the switch machine and affect its operation after it comes loose due to vibration or other factors, this utility model designs an anti-loosening structure: Specifically, the bottom plate 1021 of each slide device 102 is provided with two fourth through holes 10211 at the positions corresponding to the two third threaded connection through holes (for screwing in the first fastener 3) on the welding block 1023.

[0144] The diameter of the fourth through hole 10211 is smaller than the head diameter of the first fastener 3. This design prevents the first fastener 3, located inside the slide base plate 1021 of the first fastener 3, from falling outward through the through hole.

[0145] The first fastener 3 passes through the countersunk mounting hole 20101 on the housing 201 and is then fixedly connected to the third threaded connection through hole on the welding block 1023 of the sliding device 102.

[0146] It should be noted that the fourth through hole 10211 of the slide base plate 1021 is used to allow the worker to insert an Allen wrench into the slide device 102 through its inner cavity to tighten the first fastener 3, while also preventing the first fastener 3 from falling outward.

[0147] The diameter of the fourth through hole 10211 is larger than the diameter of the internal hex 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 slide groove device 102 together, the bottom surface of the video acquisition component 2 is pressed against the inner wall of the bottom surface of the slide groove device 102, and there is a gap between the tail of the first fastener 3 and the guide slide groove 1025. 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. Then, the operator passes an Allen wrench through the fourth through hole 10211 of the slide groove base plate 1021 and uses the Allen wrench to fasten the first fastener 3 into the third threaded connection through hole on the welding block 1023.

[0149] When the first fastener 3 loosens from the video acquisition component 2 and falls onto the inner wall of the bottom surface of the slide device 102 due to vibration or other factors, since the diameter of the through hole (i.e., the fourth through hole 10211) on the bottom surface of the slide device 102 at the corresponding position of the first fastener 3 is smaller than the diameter of the head 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 loosening, and will not fall from the slide device 102 into the switch machine, thus avoiding affecting the normal operation of the switch machine.

[0150] In this utility model, specifically in its monitoring device, a limiting design is incorporated, as detailed below:

[0151] When all four first fasteners 3 become loose from the video acquisition component due to vibration or other factors, a limiting structure is designed for the video acquisition component 2 to prevent it from sliding out in the reverse direction of the push-in direction.

[0152] The limiting structure design is as follows: A spring plunger 205 is installed in the middle of the left side plate of the video acquisition component 2 housing. The spring pin on the spring plunger 205 can elastically extend and retract. When the video acquisition component 2 slides into the guide groove 1025, the spring plunger 205 is pressed down, causing the spring pin to compress until it is flush with the left side plate 2014 of the video acquisition component 2 housing, allowing the video acquisition component 2 to slide smoothly into the guide groove 1025. When the spring pin slides to the limiting hole position on the side wall of the groove device 102, the spring pin springs in and passes through the limiting hole on the side wall of the groove device 102, limiting the video acquisition component 2 in the sliding direction and preventing it from loosening and sliding out of the groove device 102, thereby avoiding any impact on the normal operation of the switch machine.

[0153] In practice, the blind mounting hole of the left side plate 2014 of the video acquisition component 2 housing is interference-fitted with the spring plunger 205, making it difficult for the spring plunger 205 to come loose from the housing of the video acquisition component 2.

[0154] In summary, with the anti-detachment design and limiting design of the device of this utility model, the video monitoring component and the first fastener will not fall off into the switch machine, thereby avoiding affecting the operation of the switch machine and having a high degree of safety.

[0155] After testing, this utility model provides a video monitoring device for the automatic switch and roller inside the switch machine, which is highly reliable, has strong anti-interference ability, and is highly safe. It 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 also provides a switch machine, which includes the monitoring device described above, and a lower housing 4 of the switch machine;

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

[0158] Inside the lower housing 4 of the switch machine, there is an automatic opening and closing device 5 and two rollers 6;

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

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

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

[0163] In terms of specific implementation, it should be noted that the switch machine of this utility model is basically the same as the ZDJ9 switch machine produced by Tianjin Railway Signal Co., Ltd. The difference is that the structure of the switch machine cover has been improved, a special switch machine modified cover 1 has been designed, and a new video acquisition component 2 has been designed.

[0164] In practice, the bottom rear side of the switch machine modified cover 1 is hinged (i.e., rotatably connected) to the top rear side of the switch machine lower housing 4.

[0165] To better understand the technical solution of this utility model, the working process of this utility model is described below.

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

[0167] Then, the video monitoring component 2 and the first fastener 3 are pushed together into the sliding device 102. When the video acquisition component 2 slides into the sliding device 102 (sliding direction, such as...), Figure 10 (As shown in direction A), the bottom plate 2013 of the video acquisition component 2 is pressed against the inner wall of the bottom surface of the slide device 102. The tail of the first fastener 3 has a gap from the guide slide. During the sliding process, the first fastener 3 and the slide device 102 will not interfere with each other, and the video acquisition component 2 can slide smoothly into the slide device 102.

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

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

[0170] 1. This utility model is a video monitoring device for the automatic opening and closing device and rollers inside a ZDJ9 switch machine. By using a video acquisition component installed on the modified cover of the ZDJ9 switch machine, it is possible to collect video data on the changes in the position of the moving and stationary contacts of the automatic opening and closing device inside the switch machine, the fixing bolts of the moving and stationary contacts, and the status of the rollers, thereby realizing remote online monitoring of the turnout switching equipment.

[0171] 2. This utility model can cover the entire range of motion of the automatic opener and roller, without any blind spots;

[0172] 3. This utility model adopts an anti-detachment design and a device limiting design to reliably connect the first fastener to the video acquisition component, preventing it from falling into the switch machine due to vibration or other factors, thus avoiding affecting the normal operation of the switch machine, ensuring the safe operation of the switch machine, and having higher safety.

[0173] 4. This utility model adopts a sealed design, which is waterproof and dustproof;

[0174] It should be noted that, for this utility model, on the one hand, a sealing gasket (i.e., a sealing ring) is provided between the top surface of the box and the top cover in the video monitoring component 2, which can prevent water and dust from entering the interior of the video monitoring component 2 from the top surface of the box; on the other hand, the bottom surface of the box is covered with a frosted panel and a transparent panel, which completely seals 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, preventing 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, thereby achieving good waterproof and dustproof functions.

[0175] 5. With respect to this utility model, it is installed inside the cover of the switch machine, eliminating the need to drill additional mounting holes on the switch machine and thus not affecting the protection level of the switch machine.

[0176] 6. In this utility model, 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, harsh weather, high temperature environments, and motor interference.

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

[0178] 7. This utility model is easy to disassemble, which facilitates the daily maintenance and repair work of the switch machine by the staff.

[0179] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
