[0030] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0031] To address the aforementioned issues, this application provides a subway track clearance measurement vehicle for rapid measurement in complex environments. The vehicle includes a track trolley 10, a support 20, a left first clearance indicator bar 30, a right first clearance indicator bar 40, and a top clearance indicator bar 50. The track trolley 10 can move along the subway track. The support 20 is mounted on the track trolley 10. The left first clearance indicator bar 30 and the right first clearance indicator bar 40 are respectively positioned on the left and right sides of the support 20. The top clearance indicator bar 50 is located at the top of the support 20. By moving the track trolley 10, the track trolley 10 drives the left first clearance indicator bar 30, the right first clearance indicator bar 40, and the top clearance indicator bar 50 to sweep along the track line, clearly identifying whether equipment along the subway line infringes on the clearance. The clearance indicator bars simulate the infringement boundary, making measurement quick and convenient, and enabling timely detection of protruding single rebars, drooping lines, etc.
[0032] The track trolley 10 includes a body 11 and wheels 12, the wheels 12 being rotatably mounted on the body 11, and the track trolley 10 being able to travel along the track of the section to be inspected; the bracket 20 is detachably mounted on top of the body 11; the left first width indicator bar 30 is detachably and fixedly connected to the bracket 20, and the left first width indicator bar 30 is located on the left side of the track trolley 10 in the direction of travel along the height of the track trolley 10; the right first width indicator bar 40 is detachably and fixedly connected to the bracket 20, and the right first width indicator bar 40 is located on the right side of the track trolley 10 in the direction of travel along the height of the track trolley 10; the top width indicator bar 50 is located along the width of the track trolley 10, and the top width indicator bar 50 is detachably and fixedly connected to the bracket 20.
[0033] like Figure 1 and Figure 4 As shown, the subway track clearance vehicle for rapid measurement in complex environments also includes a second left-side width indicator bar 60. The second left-side width indicator bar 60 is movably mounted on the bracket 20 along the height direction of the track trolley 10, and the second left-side width indicator bar 60 can move from a first predetermined left-side position to a second predetermined left-side position. The width distance from the first predetermined left-side position to the center of the track trolley 10 is the first left-side center distance, and the width distance from the second predetermined left-side position to the center of the track trolley 10 is the second left-side center distance. The first left-side center distance is less than the second left-side center distance.
[0034] The subway track clearance vehicle for rapid measurement in complex environments also includes a second right-side width indicator bar 70. The second right-side width indicator bar 70 is movably mounted on the bracket 20 along the height direction of the track trolley 10, and the second right-side width indicator bar 70 can move from a first predetermined position on the right to a second predetermined position on the right. The width distance from the first predetermined position on the right to the center of the track trolley 10 is the first right-side center distance, and the width distance from the second predetermined position on the right to the center of the track trolley 10 is the second right-side center distance. The first right-side center distance is less than the second right-side center distance.
[0035] According to train operation safety requirements, the width limit requirements for straight sections differ from those for curved sections. For curved sections (where there are no superelevation sections in the depot), the lateral clearance needs to be widened based on the straight section clearance. This application incorporates a second width indicator rod 60 on the left side of the support 20, rotatably connected to the support 20 via a connecting rod. When the track trolley 10 is on a straight section, width measurement is performed using the first width indicator rod 30 on the left and the first width indicator rod 40 on the right. When the track trolley 10 is on a curved section, rotating the connecting rod causes either the second width indicator rod 60 on the left or the second width indicator rod 70 on the right to extend outwards to the outside of the first width indicator rod 30 on the left and the first width indicator rod 40 on the right. Clearance detection is then performed using either the second width indicator rod 60 on the left or the second width indicator rod 70 on the right. Clearance detection can be performed on both continuous straight and curved sections without changing the measuring equipment. The operation is convenient and quick.
[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the subway track clearance vehicle for rapid measurement in complex environments also includes a lighting device 80 and a power supply 81. The power supply 81 is connected to the lighting device 80 and is used to supply power to the lighting device 80. The lighting device 80 is fixedly installed on the bracket 20, and the power supply 81 is fixedly installed on the vehicle body 11.
[0037] For track renovation construction, to avoid disrupting operations, most work can only be carried out at night. The lighting equipment 80 installed on the support 20 not only provides illumination for clearance detection but can also be used as mobile lighting equipment for other construction work by the subway track clearance vehicle, which is capable of rapid measurement in this complex environment. It can move along the track easily. The support 20 has a certain height, and the lighting equipment 80 is mounted on it, providing a wide illumination range.
[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the subway track clearance vehicle for rapid measurement in complex environments also includes a drive motor 82, which is connected to the wheel 12 and is used to drive the wheel 12 to rotate, thereby driving the track trolley 10 to travel along the track of the section to be inspected.
[0039] In this embodiment, the movement of the track trolley 10 is driven by a motor, making its movement more effortless and convenient. Specifically, the driving process can employ either a dual-motor drive or a single-motor drive. A dual-motor drive uses two motors, respectively located on the left and right sides of the track trolley 10, connected to the wheels 12 via transmission components, driving the wheels 12 to rotate and thus moving the track trolley 10 on the track. A single-motor drive uses one motor to simultaneously drive both wheels on the left and right sides of the track trolley 10. The wheels on both sides can be connected via an axle to achieve simultaneous driving of both wheels by a single motor. Control can be achieved via buttons on the track trolley 10 or by a wireless remote control. The control cabinet on the track trolley 10 contains a controller, a motor driver, and a communication module. The controller can be a programmable logic controller (PLC), the motor driver can be a frequency converter, and the communication module can be a wireless communication module. The motor driver is connected to the drive motor 82 and controls its output. The PLC communicates with the motor driver, transmitting control commands and receiving motor status information detected by the motor driver. The programmable controller (PLC) connects and communicates with the communication module. The PLC is used to receive control commands from the communication module and transmit device status information to the communication module.
[0040] In this example, a motor driver is used to drive the motor, which can control the motor's start and stop as well as the output speed during operation, so that the track trolley 10 can start and stop smoothly, move forward slowly for measurement, and quickly return to the predetermined location.
[0041] like Figure 1 and Figure 3 As shown, the subway track clearance vehicle for rapid measurement in complex environments also includes multiple distance detection devices 83, which are respectively installed on the right first width indicator bar 40, the right first width indicator bar 40 and the top width indicator bar 50.
[0042] In this embodiment, the distance detection device 83 can be a laser rangefinder, which can accurately and quickly measure the distance between the object being measured and the laser rangefinder. By moving the track trolley 10, the laser rangefinder can measure the distance between the equipment along the track and the laser rangefinder. Simultaneously, the measured data can be collected by a data acquisition device, and key data can be marked using a computer, or a 3D model of the railway clearance equipment can be drawn. The marked data can also be fed back to the programmable controller. The track trolley 10 can be equipped with an audible and visual alarm or a display screen. The programmable controller controls the audible and visual alarm to issue an audible and visual alarm or displays alarm information on the display screen.
[0043] like Figure 1 and Figure 2 As shown, the subway track clearance vehicle for rapid measurement in complex environments also includes a braking device 84, which is mounted on the vehicle body 11 and is used to provide braking force to the wheels 12.
[0044] In this embodiment, brake pads are installed on the wheels 12, and brake calipers are installed on the vehicle body 11. These calipers can clamp the brake pads installed on the wheels 12, thereby braking the track trolley 10. The brake calipers can be electric brake calipers, with electrical power coming from the power supply 81 and control commands coming from the programmable controller.
