Description

Technical Field

[0002] In my country's railway transportation, locomotives and vehicles use locomotive signals to control instructions such as passing, prohibiting passage, passing on the side line, guiding, and no code.

For the lines in the vehicle maintenance depot or temporary maintenance section, traditional signal encoders have problems such as lack of flexibility and lack of safety during use, and the position of the encoder needs to be repeatedly adjusted on both sides of the track. There will be insufficient signal coverage, affecting the quality of the signal and the reliability of transmission, which may lead to deviations in the judgment and processing of the vehicle status, increase the risk and workload of vehicle maintenance, lead to inefficient vehicle maintenance, and increase the workload and risk of operators.

Specifically, the rod body is divided into two parts folded to each other by the mechanical folding arm 4, so that the whole can be folded, so that the longer rod body can be convenient to carry, and the coding rod switch 1 and the telescopic rod 7 are respectively arranged at both ends of the rod body, and can be operated after being retracted, the PCB board 3 is arranged on the side close to the coding rod switch 1, the telescopic rod locking mechanism 6 is arranged corresponding to the telescopic rod 7, the charging socket 2 is arranged on the telescopic rod 7, for charging the battery 5, the rod body is hollow, an electrical connection cable is arranged in the rod body and is not affected by the mechanical folding arm 4, the various components inside the rod body are electrically connected through the cable, and the battery 5 is arranged in a bar shape and placed in the rod body.

[0020] The rod body is made of lightweight and high-strength material, which not only ensures the solidity of the structure but also reduces the overall weight, making it easier for daily vehicle inspection and maintenance.

[0021] The telescopic rod 7 is responsible for controlling the telescopic movement of the rod body. The telescopic rod 7 adopts an electric telescopic rod structure. The telescopic rod 7 includes a positioning rod and a telescopic rod. The positioning rod and the telescopic rod slide relative to each other. A screw structure is fixedly arranged inside the telescopic rod, and two strip openings connected to the inside are symmetrically arranged on the telescopic rod. Two fixed blocks extending into the two strip openings are symmetrically fixed inside the positioning rod, and the two fixed blocks are threadedly connected to the screw structure. A driving component for driving the screw structure to rotate is fixed inside the telescopic rod. The driving component can adopt an electrically driven motor structure. When the screw structure is driven to rotate, the telescopic rod and the positioning rod can be driven to move relative to each other through the threaded structure.

[0022] The locking mechanism is a key part of the telescopic rod 7, which can automatically lock the rod body after it is extended to a specified position to prevent the rod body from moving or shaking under the action of external forces.
