Description

A collision avoidance control device for the rotating conveyor belt of a railway material transport car Technical Field

[0001] This utility model belongs to the field of railway self-propelled equipment operation safety technology, specifically relating to a collision prevention control device for the rotating conveyor belt of a railway material transport vehicle. Background Technology

[0002] With the continuous increase in the operating mileage of railways in my country, railway maintenance work is becoming increasingly heavy. Material transport cars, used for transporting and dumping ballast, are frequently used in railway engineering construction. During operations, the rotating conveyor belt of the material transport car may encroach on the construction and vehicle clearance limits of adjacent lines when rotating left and right. Therefore, in actual operation, it is prohibited for the rotating conveyor belt to rotate towards the side of an unenclosed adjacent line. When material transport cars are used for ballast dumping with rotating conveyor belts, safety monitoring mainly relies on the operators. However, due to human negligence and other external factors, there is a risk that the rotating conveyor belt may collide with overhead contact line supports or other equipment. Therefore, there is a pressing need to add obstacle avoidance detection functions to the rotating conveyor belt on-site. Furthermore, improving vehicle safety through technological means has become an inevitable trend.

[0003] Given that there are currently no relevant devices for preventing collisions with the rotating conveyor belts of railway material transport vehicles, it is necessary to develop a collision prevention control device for the rotating conveyor mechanism of railway material transport vehicles. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems and shortcomings by providing a collision prevention control device for the rotating conveyor belt of a railway material transport vehicle. This device is used to predict and alarm potential collisions between the rotating conveyor belt and contact wire poles or other equipment when the conveyor belt is rotating and extending to throw materials, thereby reducing the intensity of on-site personnel monitoring and enhancing the safety assurance capabilities of on-site construction.

[0005] The technical solution of this utility model is: a collision prevention control device for the rotating conveyor belt of a railway material transport vehicle, comprising:

[0006] Radar sensors used to detect obstacles in the operating environment of material transport vehicles;

[0007] Two anti-collision mechanisms are symmetrically and rotatably mounted on both sides of the front end of the rotary mechanism.

[0008] Position sensors used to detect the position of each anti-collision mechanism;

[0009] Speed ​​sensors used to detect the speed of a vehicle;

[0010] A data acquisition module for collecting signals from position sensors, speed sensors, and radar sensors;

[0011] Alarm devices and displays used to output alarm information;

[0012] And a host module for receiving and processing the detection signals collected by the data acquisition module to control the alarm device and the rotary mechanism.

[0013] It also includes a remote controller for controlling the movement, stopping and turning mechanisms of the material transport vehicle, which is connected to the host module.

[0014] The output terminal of the host module is connected to the data output module, and the data output module is connected to the rotary solenoid valve and the brake solenoid valve. It is used to control the rotary solenoid valve and the brake solenoid valve to operate according to the control signal sent by the remote controller and the detection signal collected by the data acquisition module after passing through the host module and the data output module.

[0015] The rotary solenoid valve is installed on the control oil circuit of the rotary cylinder on the rotary mechanism;

[0016] The brake solenoid valve is installed in the control oil circuit of the travel cylinder of the vehicle body.

[0017] The vehicle body is equipped with a rotation displacement sensor for detecting the rotation displacement of the rotation mechanism.

[0018] The display screen is connected to the main module and is used to display information on obstacles in the working environment of material transport vehicles detected by radar sensors.

[0019] There are four radar sensors, which are symmetrically arranged in pairs on the front middle part of the side of the rotary mechanism.

[0020] The alarm device includes a voice control module and a speaker.

[0021] The anti-collision mechanism includes a contact rod located on the side of the rotary mechanism. The contact rod is hinged to the side of the rotary mechanism via two or more support rods, and a compression spring is connected to the middle of each support rod and the side of the rotary mechanism.

[0022] A second contact rod is mounted on the front side of the first contact rod, which is bent towards the front side of the rotary mechanism.

[0023] The rotary mechanism has limit rods welded to both sides of the middle section, which are perpendicular to the contact rod. The limit rods are located behind the contact rod and have elongated holes through which the rear end of the contact rod passes.

[0024] The position sensor is mounted on the rotary mechanism via a bracket, and the detection surface of the position sensor is parallel to the lower surface of the support rod of the anti-collision mechanism.

[0025] This invention can effectively monitor the operating environment of material transport vehicles, thereby avoiding the major risk of collisions between the rotating mechanism of the material transport vehicle and the contact wire pole or other obstacles around the line due to human negligence.

[0026] This utility model addresses the safety hazards caused by negligence of monitoring personnel during the rotation and ballast throwing process of the material slewing mechanism from a practical application perspective. It also provides warnings and alerts regarding obstacles in the working environment, reminding on-site operators to adjust the rotation position of the slewing mechanism in a timely manner to avoid collisions with other obstacles. By employing technical prevention measures, it further enhances the safe use of vehicles on site. Attached Figure Description

[0036] As shown in Figures 1, 2, 3, and 4, this utility model includes a radar sensor capable of detecting obstacles in the working environment of a material transport vehicle, a speed sensor 17 for detecting the running speed of the vehicle body 4, an anti-collision mechanism, a position sensor for detecting the position of each anti-collision mechanism 2, a data acquisition module 116, an alarm device, a display screen 118, a host module 111, and a remote controller 19 for controlling the movement, stopping, and turning mechanisms of the material transport vehicle. The data acquisition module 116 is used to collect signals from the position sensor, speed sensor 17, and radar sensor, and the host module 111 is used to receive and process the detection signals collected by the data acquisition module 116 to control the alarm device and the turning mechanism 3.

[0037] There are four radar sensors: the front left radar sensor 11 and the front right radar sensor 18 are mounted on both sides of the front end of the rotary mechanism 3 to detect the status of obstacles in front of the vehicle body 4; the left radar sensor 13 and the right radar sensor 16 are mounted in the middle of the left and right sides of the rotary mechanism 3 to detect the status of obstacles on the left and right sides of the vehicle body 4; and the speed sensor 17 is mounted on the rotating wheel of the vehicle body 4.

[0038] There are two anti-collision mechanisms, symmetrically installed on both sides of the rotating mechanism 3. Correspondingly, there are two position sensors: a left position sensor 12 and a right position sensor 15, installed on the left and right sides of the rotating mechanism 3, respectively. These sensors detect the actual working state of the anti-collision mechanism system 2 when the left and right anti-collision mechanisms collide with external obstacles. The anti-collision mechanism includes a first contact rod 23 and a second contact rod 21. The first contact rod 23 is flush with the side of the rotating mechanism 3 and hinged to the side of the rotating mechanism 3 via two support rods 24. The support rods 24 are initially tilted towards the rear of the vehicle body. A compression spring 212 connects the support rod 24 to the side of the rotary mechanism 3. One end of the contact rod 21 is connected to the contact rod 23 by two hinges, and the other end is bent at an angle towards the front of the rotary mechanism 3. When the left contact rod 23 encounters an obstacle, the contact rod 23 tilts, the support rod 24 moves, and the spring is stretched. After the support rod 24 moves, the left position sensor 12 detects the action signal, and the main module 111 controls the data output module 114 to output the action signal of the brake electronic control valve 117, controlling the vehicle body 3 to stop urgently. The same right contact rod action control logic is the same as the left contact rod control logic, and will not be described in detail in this embodiment.

[0039] On both sides of the middle of the rotary mechanism 3, a left limiting rod 25 and a right limiting rod 210, perpendicular to the contact rod 23, are welded. The left limiting rod 25 and the right limiting rod 210 are located behind the corresponding contact rod 23. The left limiting rod 25 and the right limiting rod 210 have elongated holes through which the rear end of the contact rod 23 passes. When the contact rod 23 collides, it moves within the elongated holes of the limiting rods. When the contact rod 23 is flush with the side of the rotary mechanism 3, it is located at the outer end of the elongated hole (away from the side of the rotary mechanism 3). The left limiting rod 25 and the right limiting rod 210 are welded and fixed to the rotary mechanism 3.

[0040] Both the left position sensor 12 and the right position sensor 15 are proximity switches. During installation, the detection surfaces of the left position sensor 12 and the right position sensor 15 are parallel to the surface of the support rod 24 of the corresponding anti-collision mechanism, ensuring that the data acquisition module 116 can detect the action signal when the anti-collision mechanism is activated.

[0041] The vehicle body 4 is equipped with a rotation displacement sensor 14 for detecting the rotation displacement of the rotation mechanism 3. The rotation displacement sensor 14 is a pull rope sensor. When the rotation mechanism 3 moves left and right, the displacement of the pull rope of the sensor 14 changes. The data acquisition module 116 can detect the action signal and use it to determine whether the rotation mechanism 3 is rotating. If it is rotating, the host module 111 will process the information returned by the radar sensor accordingly.

[0042] The alarm device includes a voice control module 112 and a speaker 113.

[0043] As shown in Figures 4 and 5, the data acquisition module 116 and the remote controller 19 are connected to the input terminal of the host module 111. The output terminal of the host module 111 is connected to the data output module 114. The data output module 114 is connected to the rotary solenoid valves (left rotary solenoid valve 110 and right rotary solenoid valve 115) and the brake solenoid valve 117. The rotary mechanism 3 detects the status of obstacles in the working environment through the front left radar sensor 11, the front right radar sensor 18, the left radar sensor 13, and the right radar sensor 16. When an obstacle affecting the rotary mechanism 3 is detected in the working environment, the obstacle information can be displayed on the display screen 118. The data acquisition module 116 collects the speed signal measured by the speed sensor 17 of the vehicle body 4. The host module 111 determines the speed of the vehicle body 4 based on the speed of the vehicle body 4. If a collision is likely to occur after processing the signal and the location signal of obstacles in the working environment, control information will be sent to the voice module 112. The speaker 113 of the voice module 112 will broadcast the alarm information. According to the alarm broadcast information, the remote control 19 will send the operation command to the host module 111. The host module 111 will control the data output module 114 to output the action signal to the left solenoid valve 110, the right rotary solenoid valve 115, or the vehicle body 4 brake solenoid valve 117. The host module 111 can be a PLC controller. It is a mature technology to receive signals from the data acquisition module 116 and the remote control 19 through the PLC controller and control the alarm device, the display screen, the vehicle body brake solenoid valve 117 and the rotary solenoid valve of the rotary mechanism 3. This embodiment will not be described in detail.

[0044] Due to the complex railway operating environment, oversights in personnel protection are inevitable during operation. Therefore, four radar sensors are installed to monitor obstacles in front of and to the sides after the slewing mechanism rotates. When obstacles are detected in front of or to the sides, the main module 111 issues an alarm. At the same time, based on the distance to the detected obstacle and the detected speed signal, it controls the car body 4 to stop and the slewing mechanism 3 to stop moving, thereby avoiding collision between the slewing mechanism and the obstacle. In addition, the rotation of the slewing mechanism 3 can be controlled by the remote controller 19, allowing manual operation to rotate the slewing mechanism to a safe position (where there is no possibility of collision with the obstacle).

[0045] If the operator fails to operate the slewing mechanism 3 in a timely manner according to the alarm information or if the obstacle detection radar malfunctions, the anti-collision mechanism of the slewing mechanism 3 will contact the obstacle. The left position sensor 12 and / or the right position sensor 15 will send a signal to the main module 111. The main module 111 will issue an alarm information and control the vehicle body 4 to stop and the slewing mechanism 3 to stop moving, thereby preventing the collision accident from becoming more serious.

[0046] The host module 111 processes and calculates the received position sensor signals and sends instructions to other output devices. The data acquisition module 116 acquires signals from the left and right slewing detection sensor 14, the left radar sensor 13, the right radar sensor 16, the left contact rod action sensor 12, the right contact rod action sensor 15, and the speed sensor 17. The host module 111 receives the signals acquired by the data acquisition module 116 and the control instructions sent by the remote controller 19, processes them, and sends them to the voice module 112. After receiving the position alarm signal sent by the host module 111, the voice module 112 broadcasts an alarm through the speaker 113, and simultaneously controls the data output module 114 to output control instructions to the solenoid valves, controlling the left slewing solenoid valve 110 of the slewing mechanism 3, or the right slewing solenoid valve 115, or the vehicle body 4 brake solenoid valve.
