Description

Technical Field

[0001] This utility model relates to the field of self-propelled equipment, and in particular to a warning device for self-propelled equipment. Background Technology

[0002] Self-propelled special equipment refers to rail vehicles that operate on railway lines, possessing their own power and special functions, and are mainly used for the construction and maintenance of railway infrastructure. To ensure traffic safety and prevent accidents, warning signs are usually placed on the tracks of self-propelled equipment to indicate the parking or working area of ​​the equipment, preventing other vehicles or personnel from encroaching on the safety clearance. Warning signs are also placed in temporary work areas such as maintenance and construction sites to remind drivers to slow down or pay attention to abnormal situations.

[0003] Traditional warning signs are erected between two railway tracks using wooden or steel posts, and are secured by soil and rocks. Installation and dismantling are cumbersome, and they are prone to tipping over under wind or other external forces, or when the soil and rocks are loose.

[0004] Therefore, a technical solution is needed to address the technical problems of cumbersome installation and removal, and the risk of tipping over, when warning signs for self-propelled equipment are inserted between two rails using wooden or steel posts. Utility Model Content

[0005] The purpose of this utility model is to overcome the technical problems of existing warning signs for self-propelled equipment, which are inserted between two rails by wooden or steel posts, resulting in cumbersome installation and removal and easy tipping over. This utility model provides a warning device for self-propelled equipment.

[0006] This utility model provides a warning device for self-propelled equipment, including a warning sign, a support rod at the bottom of the warning sign, a support plate at the bottom of the support rod, a first clamping plate and a second clamping plate at the bottom of the support plate, a clamping interval formed between the first clamping plate and the second clamping plate, the distance between the first clamping plate and the second clamping plate being adapted to the width of the rail head, and a fastening bolt provided on the second clamping plate, the fastening bolt being able to extend into the clamping interval.

[0007] This utility model discloses a warning device for self-propelled equipment. In use, the support plate at the bottom of the support rod is pressed against the rail head tread. The first clamping plate and the second clamping plate are respectively clamped on the two sides of the rail head. By rotating the fastening bolt on the second clamping plate, the fastening bolt is tightened against the side of the rail head, thereby achieving relative fixation between the support rod and the rail head. It is easy to install and disassemble, and the rigid connection structure is stable and not easy to tip over.

[0008] Preferably, a first sleeve is provided on the outer side of the second clamping plate, the first sleeve is connected to the clamping area, and the fastening bolt is threadedly connected to the first sleeve.

[0009] To reduce the weight of the entire device, neither the first nor the second clamping plate can be made too thick. Therefore, if the first fastening bolt is tightened directly through the second clamping plate, it is prone to loosening and damage. The first sleeve can significantly extend the effective engagement length of the fastening bolt thread, thereby improving the fastening bolt's resistance to loosening and clamping stability under vibration.

[0010] Preferably, the bottom of the first clamping plate is provided with a horizontal plate, the distance between the horizontal plate and the support plate is adapted to the height of the rail head, and a limiting range is formed between the horizontal plate and the support plate.

[0011] The horizontal plate abuts against the lower jaw of the rail head, which restricts the rotation of the warning device and improves the anti-overturning ability of the warning device.

[0012] Preferably, the bottom of the second clamping plate can extend to below the lower jaw of the rail head, the fastening bolt is disposed on the upper part of the second clamping plate, and the portion of the second clamping plate extending out of the lower jaw of the rail head is provided with a limiting bolt, which can extend into the lower jaw of the rail head and abut against the rail web.

[0013] The fastening bolt passes through the upper part of the second clamping plate and presses against the side of the rail head. The limiting bolt passes through the lower part of the second clamping plate and presses against the rail web. On the one hand, this improves the stability of the clamping. On the other hand, the limiting bolt passes through the lower part of the rail head jaw and has a similar limiting effect to the cross plate, which can limit the rotation of the warning device.

[0014] Preferably, a second sleeve is provided on the outer side of the second clamping plate, the second sleeve is connected to the inner side of the second clamping plate, and the limiting bolt is threadedly connected to the second sleeve.

[0015] The second sleeve functions similarly to the first sleeve, significantly extending the effective engagement length of the limit bolt thread and improving the limit bolt's resistance to loosening and clamping stability under vibration.

[0016] Preferably, the distance from the bottom of the second clamping plate to the support plate is D, and the height of the rail head is d, where 2cm≤Dd≤5cm.

[0017] After the warning device is installed on the rail, the second clamping plate extends downwards at least 2cm beyond the lower jaw of the rail head to ensure that the limiting bolt has sufficient installation space. At the same time, the second clamping plate extends downwards at no more than 5cm beyond the lower jaw of the rail head to avoid problems such as increased weight and installation interference caused by the second clamping plate being too long.

[0018] Preferably, the warning sign includes a frame and a light strip. The frame is connected to the top of the support rod, and an identification plate is provided inside the frame. The light strip is arranged around the inner wall of the frame.

[0019] By installing light strips on the inner ring of the frame, the warning signs can be illuminated at night or in low-light environments, making it easier for drivers or workers to accurately identify the location of the warning signs in dim conditions.

[0020] Preferably, the device further includes a storage battery, which is electrically connected to the lamp strip, and a baffle is provided at the bottom of the frame, with the storage battery disposed at the bottom of the baffle.

[0021] By setting up a battery to independently power the light strip on the frame, no external power supply is required, making it more convenient to use. A baffle is set at the bottom of the frame to provide a mounting base for the battery.

[0022] Preferably, the device further includes a photosensitive sensor and a PLC controller, both of which are mounted on the support rod, and the photosensitive sensor and the light strip are electrically connected to the PLC controller.

[0023] A photosensitive sensor detects the ambient light intensity in real time. When the light intensity is below a set threshold, the photosensitive sensor transmits a signal to the PLC controller, which then controls the light strip to turn on, providing illumination for the warning signs. This eliminates the need for manual operation by workers, preventing situations where the light strip is forgotten to be turned on and enhancing the safety of track work. At the same time, when the ambient light is sufficient, the controller can control the light strip to turn off, reducing unnecessary energy consumption.

[0024] Preferably, the device also includes a solar panel, which is disposed on the top of the frame and is electrically connected to the battery.

[0025] Solar panels can convert solar energy into electrical energy, which can then charge batteries without requiring staff to remove them for charging. This makes them more convenient to use and also reduces energy consumption.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] This utility model provides a warning device for self-propelled equipment. By setting a support plate at the bottom of the warning sign support rod, and setting a first clamping plate and a second clamping plate on both sides of the support plate, a clamping interval adapted to the width of the rail head is formed between the first clamping plate and the second clamping plate. The second clamping plate is tightened to the side of the rail head by fastening bolts on the side of the second clamping plate, which can realize the fixation of the warning sign on the rail. It is easy to install and remove and is not easy to tip over. Attached Figure Description

[0040] Example 1

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a warning device for a self-propelled device includes a warning sign 1, a support rod 2 at the bottom of the warning sign 1, a support plate 3 at the bottom of the support rod 2, a first clamping plate 31 and a second clamping plate 32 at the bottom of the support plate 3, a clamping interval formed between the first clamping plate 31 and the second clamping plate 32, the distance between the first clamping plate 31 and the second clamping plate 32 being adapted to the width of the rail head 101, and a fastening bolt 4 on the second clamping plate 32, the fastening bolt 4 being able to extend into the clamping interval.

[0042] In use, the support plate 3 at the bottom of the support rod 2 is placed against the tread of the rail head 101. The first clamping plate 31 and the second clamping plate 32 are respectively clamped on the two sides of the rail head 101. The fastening bolt 4 on the second clamping plate 32 is rotated, and the fastening bolt 4 is tightened against the side of the rail head 101, thereby achieving relative fixation between the support rod 2 and the rail head 101. It is easy to install and disassemble, and the rigid connection is not easy to tip over.

[0043] In one or more embodiments, the first clamping plate 31 may be provided with a horizontal plate 311.

[0044] Horizontal plate 311: Located at the bottom of the first clamping plate 31, forming a limiting range between it and the support plate 3 that is adapted to the height of the rail head 101. The horizontal plate 311 abuts against the lower jaw 102 of the rail head, which restricts the rotation of the warning device and improves the anti-overturning ability of the warning device.

[0045] In one or more embodiments, a first sleeve 321 and a second sleeve 322 may be provided on the outer side of the second clamping plate 32.

[0046] First sleeve 321: Located on the upper part of second clamping plate 32, connecting the clamping area. Its inner wall is provided with internal thread. Fastening bolt 4 is threaded into the first sleeve 321. In order to reduce the weight of the entire device, the first clamping plate 31 and the second clamping plate 32 cannot be made too thick. Therefore, if the first fastening bolt 4 directly passes through the second clamping plate 32 for fastening, there is a problem of easy loosening and damage. The first sleeve 321 can significantly extend the effective engagement length of the fastening bolt 4 thread, and improve the fastening bolt 4's anti-loosening ability and clamping stability under vibration environment.

[0047] The second sleeve 322: The bottom of the second clamping plate 32 can extend to the lower part of the rail head jaw 102. The second sleeve 322 is set on the part of the second clamping plate 32 that extends out of the rail head jaw 102. The second sleeve 322 is connected to the inner side of the second clamping plate 32. The second sleeve 322 is internally threaded with a limiting bolt 5. The limiting bolt 5 passes through the second sleeve 322 and is pressed against the side of the rail web 103. On the one hand, it improves the stability of clamping. On the other hand, the limiting bolt 5 passes through the lower part of the rail head jaw 102, which is similar to the limiting function of the cross plate 311, and can limit the rotation of the warning device. In order to facilitate the installation of the second sleeve 322 on the second clamping plate 32, after the warning device is installed on the rail 10, the second clamping plate 32 extends downward out of the rail head jaw 102 by at least 2cm to ensure that the second sleeve 322 has sufficient installation space. At the same time, the second clamping plate 32 extends downward out of the rail head jaw 102 by no more than 5cm to avoid the second clamping plate 32 being too long, which would lead to increased weight and installation interference.

[0048] In one or more embodiments, the warning sign 1 may include a frame 11, and an identification plate 13 is provided inside the frame 11.

[0049] Signage 13: Warning signs, warning symbols or reflective strips can be engraved on it.

[0050] Example 2

[0051] like Figure 1 As shown, in this embodiment, the difference from embodiment 1 is that the warning sign 1 also includes a light strip 12, which is arranged around the inner wall of the frame 11.

[0052] Self-propelled equipment (such as railcars and overhead contact line maintenance vehicles) primarily focuses their headlights on the track in front of the vehicle, with weaker side and rear illumination. Warning signs 1 may be installed at locations requiring multi-angle warnings, such as curves and intersections. Moreover, as the equipment moves, the illuminated area changes with the vehicle's turning, and some angles may be temporarily uncovered. This makes it difficult for drivers or workers to spot warning signs 1 in low-light conditions. In this embodiment, a self-illuminating light strip 12 is installed on warning signs 1. In nighttime or low-light environments, the light strip 12 illuminates warning signs 1, making it easier for drivers or workers to accurately identify the location of warning signs 1 in dim lighting conditions.

[0053] In one or more embodiments, the warning device may also include a battery 6, a photosensitive sensor 7, a PLC controller 8, and a solar panel 9.

[0054] Battery 6: Battery 6 is electrically connected to LED strip 12. A baffle 111 can be installed at the bottom of the frame 11. Battery 6 is connected to the bottom of baffle 111. Battery 6 provides independent power to LED strip 12 on the frame 11, eliminating the need for an external power source and making it more convenient to use.

[0055] Photosensitive sensor 7: It can monitor the environmental pipeline in real time. When the light is lower than the set threshold, the photosensitive sensor 7 will transmit the signal to the PLC controller 8.

[0056] PLC controller 8: It can receive the electrical signal from photosensitive sensor 7 and send a command to light strip 12 to control light strip 12 to turn on, providing illumination for warning sign 1. No manual operation is required from the operator, avoiding the situation where the light strip 12 is forgotten to be turned on, thus enhancing the safety of track operation. At the same time, when the ambient light is sufficient, the controller can control light strip 12 to turn off, reducing unnecessary energy consumption.

[0057] Solar panel 9: Located on the top of frame 11, it is electrically connected to battery 6. It can convert solar energy into electrical energy to charge battery 6. This eliminates the need for staff to remove battery 6 for charging, making it more convenient to use and reducing energy consumption.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
