Description

Technical Field

[0001] This disclosure relates to safety equipment technology, specifically to a track beam safety device. Background Technology

[0002] Currently, the safety ropes used on tracks have buckles that are attached to the safety net. During track work, the buckle position needs to be constantly changed, which is not conducive to track workers' maintenance work on the tracks. Furthermore, since the safety net is fixed between the two track beams, there is no place to attach the safety rope when track workers move, which means that the safety rope cannot protect the personal safety of track workers and track workers are at risk of falling. Summary of the Invention

[0003] The purpose of this disclosure is to provide a track beam safety device that eliminates the need for users to constantly change the locking position of the safety rope and can automatically move with the movement of track workers, thus ensuring their personal safety.

[0013] The camera positioning processor is used to determine the working position of the track worker on the track based on the image information of the track worker, and send it to the central controller;

[0014] The central controller is used to control the drive device to drive the traveling wheels to rotate according to the working position of the track worker on the track.

[0015] Optionally, the central controller controls the drive device to drive the traveling wheels to rotate based on the working position of the track worker on the track, including:

[0016] When the work position is located on the safety net between the track beams, the drive device is controlled to drive the traveling wheels to follow the track worker's movement.

[0017] Optionally, the device further includes a first alarm device connected to the central controller, and the image information of the track operation also includes the image information of the safety rope.

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0037] It should be noted that in this disclosure, the terms "S101", "S102", etc., in the specification, claims and drawings are used to distinguish steps, and should not be construed as performing method steps in a specific order or sequence.

[0038] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0039] Reference Figure 2 As described in the background section, the existing track consists of two track beams 10 and a safety net 11 fixed between the two track beams 10. During the work process, track workers need to constantly change the position of the safety rope's buckle on the safety net 11. However, during the movement of track workers, there is no place to lock the safety rope, which makes it impossible for the safety rope to protect the personal safety of track workers.

[0040] In view of this, the present disclosure provides a track beam safety device that can automatically move with track workers during their movement, eliminating the need for track workers to constantly change the locking position of the safety rope, thus protecting the personal safety of track workers.

[0041] Figure 1 This is a structural schematic diagram of a track beam safety device according to an exemplary embodiment, with reference to... Figure 1 The device includes:

[0042] Vehicle body 1;

[0043] At least one pair of traveling wheels 2, the pairs of traveling wheels 2 are spaced apart along the width direction of the track beam 10, the traveling wheels 2 are connected to the vehicle body 1 and are used to make rolling contact with the top wall of the track beam 10;

[0044] At least one pair of limiting wheels 3 are provided, with the pairs of limiting wheels 3 spaced apart along the width direction of the track beam 10. The limiting wheels 3 are connected to the vehicle body 1 and are used for rolling contact with the side wall of the track beam 10.

[0045] The locking body 4 is mounted on the vehicle body 1 and is used to connect with the locking sub-body on the safety rope.

[0046] Among them, reference Figure 3The limiting wheels 3, connected to the vehicle body 1, can roll in contact with the inner wall of the track beam 10, meaning the two track beams 10 clamp the two limiting wheels 3. The limiting wheels 3, also connected to the vehicle body 1, can roll in contact with the outer wall of the track beam 10, meaning the two limiting wheels 3 clamp the track beam 10. The limiting wheels 3 guide the rolling direction of the traveling wheels 2, while simultaneously ensuring the balance and stability of the entire track beam safety device on the track.

[0047] For example, when track workers are working on the track, they connect the safety rope's locking buckle to the locking body 4 of the track beam safety device. The traveling wheel 2 rolls along the top wall of the track beam 10, moving the track beam safety device. The limiting wheel 3 rolls along the side wall of the track beam 10, guiding the movement of the track beam safety device on the track. During the movement of the track workers, the track beam safety device moves with them along the track beam 10, eliminating the need for workers to constantly change the safety rope's locking position. It provides locking points for the safety rope during work, ensuring the personal safety of track workers and preventing them from falling off the track.

[0048] To enable those skilled in the art to better understand the track beam safety device provided in this disclosure, the structure and working process of the track beam safety device are described in detail below with examples.

[0049] In one embodiment, the track beam safety device further includes a drive device for driving the traveling wheel 2 to rotate.

[0050] In this disclosure, a driving device provides driving force to the traveling wheels, thereby driving the traveling wheels to rotate. No external force is required, and no track workers are needed to move them. The track beam safety device can move automatically with the track workers.

[0051] In one embodiment, the system further includes an information acquisition and processing module connected to the drive device, used to acquire image information of the track operation and control the drive device to drive the walking wheel 2 to rotate based on the image information.

[0052] This disclosure acquires image information of track operation through an information acquisition and processing module, and controls the drive wheel 2 of the device to rotate according to the image information. This enables the drive device to drive the wheel according to the different working states of the track workers, making the track beam safety device move more flexibly.

[0053] In one embodiment, the information acquisition and processing module includes a dual camera consisting of two cameras 5, a camera positioning processor 6, and a central controller 7, wherein the dual cameras, the camera positioning processor 6, and the central controller 7 are communicatively connected, and the central controller 7 is connected to a driving device.

[0054] Dual cameras are used to acquire image information of track operations and send it to camera positioning processor 6. The image information of track operations includes image information of track operation personnel.

[0055] The camera positioning processor 6 is used to determine the working position of the track workers on the track based on the image information of the track workers, and send it to the central controller 7;

[0056] The central controller 7 is used to control the drive device to drive the traveling wheels 2 to rotate according to the working position of the track worker on the track.

[0057] For example, refer to Figure 1 When track workers walk on the safety net 11, the safety rope is secured to the locking body 4 of the track beam safety device, ensuring their personal safety. Dual cameras capture image information of the track workers and send it to the camera positioning processor 6. The camera positioning processor 6 determines the workers' position on the track based on the image information and sends it to the central controller 7. The central controller 7 controls the drive device to rotate the walking wheels based on the workers' position on the track, achieving flexible control of the track beam safety device.

[0058] Furthermore, refer to Figure 4 The central controller 7 is responsible for the control and information input and output of the entire track beam safety device. Therefore, the central controller 7 needs to monitor the status of each component on the track beam safety device, such as the motor 8, battery 9, camera positioning processor and dual cameras. The monitoring content includes the motor drive status, battery power, whether the camera positioning processor is working properly, and whether the dual cameras are turned on. The status of each component is transmitted to the ground equipment.

[0059] After receiving the image information transmitted by the camera positioning processor, the central controller 7 needs to make a judgment on the locking status of the safety rope and the working position of the track workers, so as to control the track beam safety device. The working position of the track workers can be on the safety net 11, on the track beam 10, or outside the track beam 10, etc. The control object of the central controller 7 is different for different working positions.

[0060] In one embodiment, the central controller 7 controls the drive device to drive the traveling wheels 2 to rotate based on the working position of the track worker on the track, including:

[0061] When the work position is on the safety net 11 between the two track beams 10, the control drive device drives the traveling wheels 2 to follow the track workers.

[0062] Reference Figure 5In step S101, the dual cameras acquire image information of the track operation and send it to the camera positioning processor 6. The image information of the track operation includes image information of the track operation personnel and image information of the safety rope.

[0063] In step S102, the camera positioning processor 6 determines the working position of the track worker on the track based on the image information of the track worker and determines the locking status of the safety rope based on the image information of the safety rope, and sends it to the central controller 7.

[0064] In step S103, when the working position is located on the safety net 11 between the two track beams 10, the central controller 7 controls the drive device to drive the traveling wheels 2 to follow the track workers.

[0065] If the track worker is on the safety net 11 between the two track beams 10, further determination is made regarding whether the track worker has moved. If the track worker moves and the distance between them and the track beam safety device increases, the drive device is controlled to drive the traveling wheels 2 to follow the track worker. If the track worker does not move, the drive device is controlled to drive the traveling wheels 2 to move a certain distance, so that the track beam safety device and the track worker remain within a first preset distance. The first preset distance is the minimum distance between the track worker and the track beam safety device without affecting the track worker's work. Automatic movement of the track beam safety device is achieved without any operation from the track worker.

[0066] In one embodiment, the device further includes a first alarm device connected to the central controller 7. The image information of the track operation also includes the image information of the safety rope. The central controller 7 is further configured to control the first alarm module to output a first alarm message when it is determined from the image information of the safety rope that the safety rope is not in a locking state.

[0067] Reference Figure 5 In step S101, the dual cameras acquire image information of the track operation and send it to the camera positioning processor 6. The image information of the track operation includes image information of the track operation personnel and image information of the safety rope.

[0068] In step S102, the camera positioning processor 6 determines the working position of the track worker on the track based on the image information of the track worker and determines the locking status of the safety rope based on the image information of the safety rope, and sends it to the central controller 7.

[0069] In step S104, if the central controller determines that the safety rope is not in a locked state based on the image information of the safety rope, it controls the first alarm module to output the first alarm information.

[0070] The first alarm module can be an audible and visual alarm, and the first alarm message is an audible and visual alarm that outputs the voice message "Warning: The safety rope is not in the locking state. Please lock it." At the same time, the indicator light flashes red or stays on. The first alarm module can also be a buzzer, and the first alarm message is a buzzer sounding to realize the alarm. This disclosure does not make specific limitations on the first alarm module.

[0071] If the safety rope is not in a locked state according to the image information, it means that the track worker has not connected the locking sub-body on the safety rope to the locking mother body of the track beam safety device. In this case, the buzzer needs to be controlled to sound to warn the track worker that the safety rope is not in a locked state and remind the track worker to connect the locking sub-body on the safety rope to the locking mother body 4 of the track beam safety device.

[0072] In one embodiment, the device further includes a second alarm device connected to the central controller 7, which is also used to control the second alarm device to output a second alarm message when the working position is located on the upper surface of the track beam 10 in a non-turnout section.

[0073] Reference Figure 5 In step S101, the dual cameras acquire image information of the track operation and send it to the camera positioning processor 6. The image information of the track operation includes image information of the track operation personnel and image information of the safety rope.

[0074] In step S102, the camera positioning processor 6 determines the working position of the track worker on the track based on the image information of the track worker and determines the locking status of the safety rope based on the image information of the safety rope, and sends it to the central controller 7.

[0075] In step S105, when the central controller 7 is located on the upper surface of the track beam in a non-switching section, it controls the second alarm device to output the second alarm information.

[0076] The second alarm device, like the first alarm device, can be an audible and visual alarm. The second alarm message is an audible and visual alarm that outputs the voice message "Warning: The safety rope is not in the locking state. Please lock it." At the same time, the indicator light flashes red or stays on. The second alarm module can also be a buzzer. The second alarm message is a buzzer sound to trigger the alarm. The first alarm message has a higher priority than the second alarm message. This disclosure does not specifically limit the second alarm module.

[0077] If the work position is located on the upper surface of the track beam 10 in a non-switching section, it indicates that the track worker is at risk of falling due to loss of footing in the non-switching section of the track beam 10. At this time, the buzzer will sound to warn the track worker that they are currently in a dangerous work area.

[0078] The existing safety ropes have no locking points when track workers pass through the turnout sections of the track, which prevents them from fulfilling their safety function. Furthermore, there are no safety nets 11 in the turnout sections, and workers need to walk on the track beams 10. In this situation, without the protection of safety ropes, track workers are in even greater danger.

[0079] In one embodiment, the central controller 7 is configured to communicate with ground equipment, and the central controller 7 is further configured to:

[0080] When the work location is on the upper surface of the track beam 10 in the turnout section, the image information of the track work is sent to ground equipment; and / or,

[0081] If the work location is outside the track beam 10, send a rescue signal to the ground equipment.

[0082] Reference Figure 5 In step S101, the dual cameras acquire image information of the track operation and send it to the camera positioning processor 6. The image information of the track operation includes image information of the track operation personnel and image information of the safety rope.

[0083] In step S102, the camera positioning processor 6 determines the working position of the track worker on the track based on the image information of the track worker and determines the locking status of the safety rope based on the image information of the safety rope, and sends it to the central controller 7.

[0084] In step S106, when the operation location is on the upper surface of the track beam 10 in the turnout section, the central controller 7 sends image information of the track operation to the ground equipment; and / or,

[0085] If the work location is on the track beam 10 in the intersection section, the central controller 7 sends the image information of the track operation to the ground equipment, so that the ground equipment operators can obtain the status of the track workers and control the drive device to drive the walking wheels 2 to maintain a second preset distance from the track workers and move with the track workers, so that the track beam safety device and the track workers are kept within the second preset distance. The second preset distance is the minimum distance between the track workers and the track beam safety device without affecting the movement of the track workers, thereby ensuring the personal safety of track workers when passing through the intersection section of the track.

[0086] In step S107, when the central controller 7 is outside the track beam 10 at the working position, it sends a rescue signal to the ground equipment.

[0087] If the work position is outside the track beam 10, it indicates that the track worker has fallen and is being held by a safety rope on the track beam safety device. The central controller box 7 ground equipment sends a rescue signal so that the ground equipment operators can obtain the status of the track worker and take rescue measures to rescue the track worker.

[0088] In one embodiment, the driving device includes a motor 8 and a battery 9. The motor 8 is connected to the walking wheel 2 through a transmission structure. The motor 8 is used to drive the walking wheel 2 to rotate. The battery 9 is used to power the motor 8 and the information acquisition and processing module.

[0089] The motor 8 provides driving force to the traveling wheels 2, causing them to rotate and thus moving the track beam safety device. The battery 9 provides 24V power to the electrical equipment on the track beam safety device. This electrical equipment powers the motor 8 and the information acquisition and processing module. By providing voltage to the electrical equipment on the track beam safety device through the battery 9, the electrical safety of the track beam safety device can be guaranteed.

[0090] In one embodiment, the vehicle body 1 is made of aluminum.

[0091] The vehicle body 1 is made of aluminum, which reduces the weight of the track beam safety device and keeps the overall weight of the track beam safety device in a relatively light state. The motor 8 outputs less driving force to drive the traveling wheels 2 to move the track beam safety device.

[0092] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
