Description

Technical Field

[0001] This utility model relates to the technical field of railway transportation, specifically to a railway hook lock. Background Technology

[0002] In the railway transportation system, the railway hook lock is a key device to ensure the safe operation of trains under abnormal circumstances. It is mainly used for manually locking turnouts during abnormal train operation such as construction and maintenance.

[0003] Traditional hook locks use a purely mechanical structure and have relatively simple functions, resulting in obvious defects: they cannot report their own location in real time. This means that managers cannot grasp the deployment status of all hook locks and the corresponding turnout opening and closing status from a global perspective, leading to low operational efficiency and a high risk of errors. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing hook locks cannot report their own location, making it impossible for managers to grasp the deployment status of all hook locks and the corresponding turnout opening and closing status from a global perspective. This results in low operational efficiency and a high risk of errors. The purpose is to provide a railway hook lock with a Beidou antenna on the receiving device, enabling managers to grasp the deployment status of all hook locks from a global perspective and determine the turnout opening and closing status based on the location of the hook locks, thereby improving operational efficiency and avoiding errors.

[0005] This utility model is achieved through the following technical solution:

[0006] A railway hook lock includes a first mechanical lock body, a second mechanical lock body, and a receiving device. The first mechanical lock body is fixedly connected to one end of a screw rod, and in the working state, the first mechanical lock body abuts against a first rail base plate. The second mechanical lock body is screwed onto the screw rod, and in the working state, the second mechanical lock body abuts against a second rail base plate. The first rail base plate and the second rail base plate are adjacent to each other, and both the first and second mechanical lock bodies are located between the first and second rail base plates. The receiving device is connected to the end of the screw rod away from the first mechanical lock body, and a Beidou antenna is installed inside the receiving device.

[0007] The beneficial effects of this utility model are that by setting both the first and second mechanical lock bodies to be connected to the screw rod and abutting against the first and second rail base plates respectively, the first and second rails can be separated by adjusting the position of the second mechanical lock body on the screw rod, thereby locking the turnout. A receiving device with a Beidou antenna is also set on the screw rod, which facilitates the management personnel to grasp the deployment of all hook locks from a global perspective and determine the open and closed status of the turnout based on the location of the hook locks, thereby improving the efficiency of related operations and avoiding errors.

[0008] In some embodiments, the first mechanical lock body is rectangular in shape, with one end connected to the screw. A first slot is provided on the first mechanical lock body, located on the side away from the second mechanical lock body. In operation, the first slot engages with and abuts against the first rail base plate. By engaging the first slot with the first rail base plate, relative sliding between the first mechanical lock body and the first rail base plate is prevented during operation, thus achieving the locking of the turnout.

[0009] In some embodiments, the second mechanical lock body is rectangular in shape, with one end connected to the screw. A second slot is provided on the second mechanical lock body, located on the side away from the first mechanical lock body. In operation, the second slot engages with and abuts against the second rail base plate. By engaging the second slot with the second rail base plate, relative sliding between the second mechanical lock body and the second rail base plate is prevented during operation, thus achieving the locking of the turnout.

[0010] In some embodiments, a locking nut is further included, which is screwed onto the screw and located between the first and second mechanical lock bodies. In the working state, the locking nut abuts against the second mechanical lock body. The locking nut restricts the rotation of the second mechanical lock body along the screw.

[0011] In some embodiments, the locking nut has a disc portion with several locking holes, and the second mechanical lock body has a positioning hole. In the working state, the anti-rotation rod passes through the locking holes and the positioning hole in sequence to restrict the rotation of the locking nut. By providing a disc portion on the locking nut, several locking holes on the disc portion, and a positioning hole on the second mechanical lock body, and by having the anti-rotation rod (such as a pin) pass through the positioning hole and the locking hole, the rotation of the locking nut is further prevented.

[0012] In some embodiments, the second mechanical lock body is provided with a connecting lug, which is located on one side of the second mechanical lock body, and the positioning hole is located on the connecting lug. The connecting lug is provided to improve the strength and rigidity of the connection point.

[0013] In some embodiments, the receiving device includes a housing, a battery, and a control motherboard. One end of the housing is provided with an internal thread that engages with the screw. The battery is electrically connected to the control motherboard. The antenna, battery, and control motherboard are all located within the housing, and the antenna is electrically connected to the control motherboard. By receiving satellite signals through a BeiDou antenna, the latitude and longitude coordinates of the current hook lock are accurately calculated. The control motherboard packages the collected location information (and locking status information) and then sends the data to a remote backend management system. The control motherboard listens in real time for instructions issued from the backend (such as parameter configuration instructions and remote retrieval instructions) and executes corresponding operations.

[0014] In some embodiments, the end of the screw that engages with the connecting internal thread is provided with an NPT thread, and the connecting internal thread is an NPT thread. By providing an NPT thread at the end of the screw that engages with the connecting internal thread, water from the environment is prevented from seeping into the housing.

[0015] In some embodiments, the device further includes a top cover. A sealing ring mounting groove is provided on the upper side wall of the box body, and a sealing ring is installed in the groove. The top cover is connected to the box body by several screws. The sealing ring is located at the bottom of the top cover and abuts against it. By providing the sealing ring, water from the environment is further prevented from entering the box body.

[0016] In some embodiments, the housing is filled with silicone rubber, which fills the gaps between the housing cavity and the battery, control motherboard, and BeiDou antenna. By filling the gaps between the housing cavity and the battery, control motherboard, and BeiDou antenna with silicone rubber, displacement of the three components can be prevented, and moisture absorption can be avoided.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. The first and second mechanical lock bodies are both connected to the screw rod and abut against the first and second rail base plates respectively. By adjusting the position of the second mechanical lock body on the screw rod, the first and second rails are separated to lock the turnout. A receiving device with a Beidou antenna is also installed on the screw rod to facilitate managers to monitor the deployment of all hook locks from a global perspective, improve the efficiency of related operations, and avoid errors.

[0019] 2. A disc portion is provided on the locking nut, and several locking holes are provided on the disc portion. The positioning hole provided on the second mechanical lock body, through which the anti-rotation rod (pin, etc.) passes, further prevents the locking nut from rotating. Attached Figure Description

[0030] Example 1

[0031] like Figures 1-3 As shown in the figure, this embodiment 1 provides a railway hook lock, including a first mechanical lock body 20, a second mechanical lock body 40, and a receiving device. The first mechanical lock body 20 is fixedly connected to one end of a screw 50, and in the working state, the first mechanical lock body 20 abuts against a first rail base plate. The second mechanical lock body 40 is screwed onto the screw 50, and in the working state, the second mechanical lock body 40 abuts against a second rail base plate. The first rail base plate and the second rail base plate are adjacent, and both the first mechanical lock body 20 and the second mechanical lock body 40 are located between the first rail base plate and the second rail base plate. The receiving device is connected to the end of the screw 50 away from the first mechanical lock body 20, and a Beidou antenna 13 is installed inside the receiving device. The Beidou antenna 13 on the receiving device facilitates the management personnel to grasp the deployment status of all hook locks from a global perspective, improves the efficiency of related operations, and avoids errors.

[0032] See Figures 1-3 The first mechanical lock body 20 is rectangular in shape, with one end connected to the screw 50. A first slot 21 is provided on the first mechanical lock body 20, located on the side away from the second mechanical lock body 40. In operation, the first slot 21 engages with and abuts against the first rail base plate. By engaging the first slot 21 with the first rail base plate, relative sliding between the first mechanical lock body 20 and the first rail base plate is prevented during operation, thus achieving the locking of the turnout.

[0033] See Figures 1-3The second mechanical lock body 40 is rectangular in shape. One end of the second mechanical lock body 40 is connected to the screw 50. A second slot 41 is provided on the second mechanical lock body 40, located on the side of the second mechanical lock body 40 away from the first mechanical lock body 20. In the working state, the second slot 41 engages with the second rail base plate and abuts against it. By providing the second slot 41 to engage with the second rail base plate, relative sliding between the second mechanical lock body 40 and the second rail base plate is prevented during operation, thus achieving the locking of the turnout.

[0034] See Figures 1-3 It also includes a locking nut 30, which is screwed onto the screw 50 and located between the first mechanical lock body 20 and the second mechanical lock body 40. In the working state, the locking nut 30 abuts against the second mechanical lock body 40. The locking nut 30 restricts the rotation of the second mechanical lock body 40 along the screw 50.

[0035] See Figures 1-3 The locking nut 30 has a disc portion 31 with several locking holes 311. The second mechanical lock body 40 has a positioning hole 23. In operation, the anti-rotation rod passes through the locking holes 311 and the positioning hole 23 in sequence to restrict the rotation of the locking nut 30. By providing a disc portion 31 on the locking nut 30 and several locking holes 311 on the disc portion 31, and a positioning hole 23 on the second mechanical lock body 40, the rotation of the locking nut 30 is further prevented by the anti-rotation rod (such as a pin) passing through the positioning hole 23 and the locking hole 311.

[0036] See Figure 3 The second mechanical lock body 40 is provided with a connecting lug 22, which is located on one side of the second mechanical lock body 40, and the positioning hole 23 is located on the connecting lug 22.
