Description

Technical Field

[0001] This utility model relates to the field of railway track monitoring technology, specifically to a railway track monitoring device. Background Technology

[0002] Turnouts, curves, and joints are collectively known as the three weakest links in railway tracks. Among them, turnouts, as switching devices for railway line changes, are the most complex in terms of technical specifications and have the highest requirements for track conditions. Therefore, appropriate monitoring equipment is needed to monitor turnouts, thereby facilitating maintenance by railway workers.

[0003] Most existing turnout monitoring equipment consists of surveillance cameras. While these cameras can monitor turnouts, they are directly exposed to the elements. In frigid regions like northern areas, rain and snow can easily seep into the camera's gaps. This meltwater freezes in the cold, affecting the camera's normal operation. Therefore, we propose a new railway track monitoring device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings and provide a railway track monitoring device.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a railway track monitoring device, including a housing and a monitoring camera installed at one end of the housing for monitoring the railway track, a heating mechanism including a water storage chamber opened in the housing for storing water, a receiving cavity for housing the monitoring camera, and multiple heating rods fixed inside the water storage chamber for heating the water, and a connecting mechanism including mounting columns fixed on both sides of the monitoring camera for driving the monitoring camera to deflect, a mounting plate rotatably connected to the end of the mounting column away from the monitoring camera, and a connecting plate sliding inside the receiving cavity, wherein the end of the mounting plate away from the mounting column is fixed to the connecting plate. Through the operation of the above components, the railway track can be monitored, thereby facilitating railway workers to maintain the turnouts and remove ice from the gaps of the monitoring camera.

[0006] Furthermore, a lead screw for driving the connecting plate to move is threaded through the top of the connecting plate. One end of the lead screw is connected to a motor fixed on the inner wall of one end of the receiving cavity for driving the lead screw to rotate. The other end of the lead screw is rotatably connected to the inner wall of the other end of the receiving cavity. By running the motor, the lead screw can be driven to rotate. Through the cooperation between the lead screw and the connecting plate, the connecting plate is driven to move.

[0007] Furthermore, the housing has an opening at the end near the monitoring camera that communicates with the receiving cavity. The monitoring camera and the mounting plate are slidably engaged with the opening. Through the opening, the movable monitoring camera and the mounting plate can enter the receiving cavity or slide to the outside of the housing.

[0008] Furthermore, drainage grooves communicating with the receiving cavity are provided at both ends of the bottom side of the housing. A baffle for blocking the drainage grooves is provided on the bottom side of the housing. A block fixed on the baffle is slidably inserted into the drainage groove. A connecting shaft is slidably inserted through the bottom end of the connecting plate. Cams are provided on both sides of the connecting plate and are fixedly sleeved on the outer wall of the connecting shaft and cooperate with the adjacent block. One end of the connecting shaft extends through to the outside of the housing and is fixed with a sealing plate for closing the opening. The other end of the connecting shaft is driven by a motor II fixed on the inner wall of the end of the receiving cavity for driving the connecting shaft to rotate. Through the operation of the above components, the opening can be closed to prevent cold air from blowing into the receiving cavity through the opening, reduce the melting rate of intermittent icing of the monitoring camera inside the receiving cavity, and drain the water inside the receiving cavity.

[0009] Furthermore, the cam slides into the adjacent drainage groove, and the housing has a through hole communicating with the receiving cavity. The connecting shaft rotates inside the through hole, and the through hole can prevent the housing from interfering with the rotation of the connecting shaft.

[0010] Furthermore, the bottom side of the housing is provided with multiple mounting slots, and the mounting slots are slidably inserted with inserts fixed to the baffle. The ends of the inserts located inside the mounting slots are fixed with multiple springs whose tail ends are fixed to the inner wall of the mounting slot ends. Through the elasticity of the springs, the inserts, baffles and plugs can be pulled to reset displacement.

[0011] Furthermore, a gear 1 is fixedly sleeved on the outer wall of the mounting column located on one side of the surveillance camera. A gear 2 that meshes with the gear 1 is provided on one side of the gear 1. An output shaft is fixedly inserted inside the gear 2. One end of the output shaft is connected to a motor 3 fixed on an adjacent mounting plate. By running the motor 3, the output shaft can be driven to rotate, which in turn drives the gear 2 to rotate, which in turn drives the gear 1 to rotate, which in turn drives the mounting column to rotate, which in turn drives the surveillance camera to deflect. At this time, the angle of the surveillance camera can be adjusted.

[0012] Furthermore, a base is provided below the housing, and a support column for supporting the housing is fixed between the housing and the base. The support column can stabilize the housing and the monitoring camera on the housing above the base.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model, through the operation of a monitoring camera, can monitor the longitudinal and vertical displacements of the straight and curved main rails of a turnout, as well as the longitudinal and vertical displacements of the switch rail heel and the turnout tail rail. By comprehensively processing the monitoring data, it can promptly grasp the development trend of major turnout defects, providing a basis for precise "condition-based maintenance," thus facilitating turnout maintenance by railway staff. The angle of the monitoring camera can be adjusted according to monitoring needs, and ice buildup in the gaps between the monitoring cameras can be removed, improving the camera's endurance. The monitoring camera can be stored and protected according to usage requirements, and water melted from the gaps between the monitoring cameras can be quickly drained. The drainage components can be unblocked to prevent impurities in the water from clogging the drainage channels, resulting in high performance.

[0014] In summary, this utility model has a reasonable structure, can monitor railway tracks, thus facilitating railway staff to maintain switches, can remove ice from the gaps of monitoring cameras, and can quickly drain the water from the melting ice in the gaps of monitoring cameras. It has high working performance and strong endurance. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Combination Figure 1 and Figure 2 This embodiment of a railway track monitoring device includes a housing 1 and a monitoring camera 2 disposed at one end of the housing 1 for monitoring the railway track. It includes a heating mechanism comprising a water storage chamber 5 formed within the housing 1 for storing liquid, a receiving cavity 6 for housing the monitoring camera 2, and multiple heating rods 14 fixed inside the water storage chamber 5 for heating the liquid. A level valve connected to the water storage chamber 5 is installed on the housing 1, allowing sufficient liquid to be injected into the water storage chamber 5. A connecting mechanism includes mounting columns 9 fixed on both sides of the monitoring camera 2 for rotating the monitoring camera 2, a mounting plate 8 rotatably connected to the end of the mounting column 9 away from the monitoring camera 2, and a connecting plate 10 sliding inside the receiving cavity 6. The end of the mounting plate 8 away from the mounting column 9 is fixed to the connecting plate 10.

[0019] The implementation principle of a railway track monitoring device in this application embodiment is as follows: Through the operation of the monitoring camera 2, the longitudinal and vertical displacements of the straight and curved main rails of the turnout can be monitored, as can the longitudinal and vertical displacements of the switch rail heel end and the longitudinal and vertical displacements of the turnout tail rail. Then, through comprehensive processing of the monitoring data, the development trend of major turnout defects can be grasped in a timely manner, providing a basis for precise "condition-based maintenance," thereby facilitating railway staff to maintain the turnout. The rotation of the mounting column 9 can drive the monitoring camera 2 to deflect, allowing for angle adjustment. When the monitoring camera 2 is affected by icing in rainy or snowy weather, affecting its normal operation, the operation of the heating rod 14 heats the water inside the water storage chamber 5. The displacement of the connecting plate 10 causes the mounting plate 8 to move, which in turn causes the mounting column 9 and the monitoring camera 2 to move. When the monitoring camera 2 enters the receiving cavity 6, the water in the heated water storage cavity 5 will heat the housing 1 and the monitoring camera 2 inside the housing 1, thereby melting the ice in the gap of the monitoring camera 2 and drying the water adhering to the outside of the monitoring camera 2. After the ice in the gap of the monitoring camera 2 inside the housing 1 is removed, the displacement of the connecting plate 10 causes the mounting plate 8 to move, which in turn causes the mounting column 9 and the monitoring camera 2 to move. When the monitoring camera 2 slides out of the receiving cavity 6 and moves to the outside of the housing 1, the monitoring camera 2 can continue to perform monitoring work, avoiding the impact of ice in the gap of the monitoring camera 2 on its normal operation.

[0020] Example 2: Combination Figure 4 This embodiment is further improved on the basis of embodiment 1 in that: the top of the connecting plate 10 is threaded with a lead screw 13 for driving the connecting plate 10 to move. One end of the lead screw 13 is connected to a motor 1 fixed on the inner wall of one end of the receiving cavity 6 for driving the lead screw 13 to rotate. The motor 1 is a forward and reverse stepper motor. The other end of the lead screw 13 is rotatably connected to the inner wall of the other end of the receiving cavity 6. Through the operation of the motor 1, the lead screw 13 can be driven to rotate. Through the cooperation between the lead screw 13 and the connecting plate 10, the connecting plate 10 is driven to move.

[0021] The housing 1 has an opening 7 at the end near the monitoring camera 2 that communicates with the receiving cavity 6. The monitoring camera 2 and the mounting plate 8 are slidably engaged with the opening 7. Through the opening 7, the movable monitoring camera 2 and the mounting plate 8 can enter the receiving cavity 6 or slide to the outside of the housing 1.

[0022] Example 3: Combination Figure 3This embodiment, based on embodiment 1, further improves upon the following: Drainage channels communicating with the receiving cavity 6 are provided at both ends of the bottom side of the housing 1; a baffle 22 for blocking the drainage channels is provided on the bottom side of the housing 1; a block 18 fixed on the baffle 22 is slidably inserted into the drainage channel; a connecting shaft 16 is slidably passed through the bottom end of the connecting plate 10; cams 17 fixedly sleeved on the outer wall of the connecting shaft 16 and cooperating with adjacent block 18 are provided on both sides of the connecting plate 10; one end of the connecting shaft 16 extends through to the outside of the housing 1 and is fixedly fitted with a closing plate 15 for closing the opening 7; the other end of the connecting shaft 16 is drively connected to a second motor fixed on the inner wall of the end of the receiving cavity 6 for driving the connecting shaft 16 to rotate; the second motor is a forward and reverse stepper motor; when the camera 2 and the mounting plate 8 are connected... After entering the cavity 6 through opening 7, the motor drives the connecting shaft 16 to rotate, which in turn drives the sealing plate 15 to rotate. At this time, the rotating sealing plate 15 can close the opening 7, preventing cold air from blowing into the cavity 6 through the opening 7, thus reducing the melting rate of the intermittent ice formation of the monitoring camera 2 inside the cavity 6. When the monitoring camera 2 intermittently melts, the melted water will fall into the cavity 6. At this time, the rotation of the connecting shaft 16 can drive the cam 17 to rotate, which can press the block 18, causing the block 18 and the baffle 22 to move vertically downward. When the block 18 and the baffle 22 open the drainage channel, the water inside the cavity 6 can be discharged through the drainage channel.

[0023] The cam 17 slides with the adjacent drainage groove. The housing 1 has a through hole that communicates with the receiving cavity 6. The connecting shaft 16 rotates inside the through hole. The through hole can prevent the housing 1 from interfering with the rotation of the connecting shaft 16.

[0024] Example 4: Combination Figure 6 Based on Embodiment 1, this embodiment further improves upon the following: multiple mounting slots 19 are provided on the bottom side of the housing 1. Inserts 20 fixed on the baffle 22 are slidably inserted into the mounting slots 19. Multiple springs 21 with their tail ends fixed on the inner wall of the end of the mounting slot 19 are fixed to the ends of the inserts 20 located inside the mounting slots 19. When the rotating cam 17 separates from the block 18, the elasticity of the springs 21 will pull the inserts 20, the baffle 22 and the block 18 to reset displacement, causing the block 18 to seal the drainage channel. When the block 18 enters the drainage channel, it can unclog the drainage channel and prevent impurities in the water from clogging the drainage channel.

[0025] Example 5: Combination Figure 5This embodiment is further improved on the basis of embodiment 1 in that: a gear 12 is fixedly sleeved on the outer wall of the mounting post 9 located on one side of the monitoring camera 2, and a gear 2 11 that meshes with the gear 12 is provided on one side of the gear 12. An output shaft is fixedly inserted inside the gear 2 11, and one end of the output shaft is connected to a motor 3 fixed on the adjacent mounting plate 8. The motor 3 is a forward and reverse stepper motor. By running the motor 3, the output shaft can be driven to rotate, which drives the gear 2 11 to rotate, drives the gear 12 to rotate, drives the mounting post 9 to rotate, and drives the monitoring camera 2 to deflect. At this time, the angle of the monitoring camera 2 can be adjusted.

[0026] A base 4 is provided below the housing 1. A support column 3 for supporting the housing 1 is fixed between the housing 1 and the base 4. The base 4 is fixed to the place of use. The housing 1 and the monitoring camera 2 on the housing 1 can be stabilized on the base 4 through the support column 3.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
