Description

Technical Field

[0001] The utility model relates to the technical field of line alignment devices, and in particular to a line alignment device for electrical debugging of subway vehicles. Background Art

[0002] Electrical debugging mainly refers to the adjustment and testing of electrical equipment. It is a process in subway vehicle debugging after the equipment installation work is completed and before it is put into production operation. It cannot be put into operation directly after the installation is completed on site according to the design drawings. In order to ensure the safe, reasonable and normal operation of the equipment and avoid accidents that cause economic losses to the country and casualties, debugging work must be carried out. Only after passing the electrical debugging can the electrical equipment be put into operation.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN209946220U discloses a wiring device for subway electrical debugging, including a wiring device body, a replacement mechanism and a fixing mechanism, the front surface of the wiring device body is fixedly connected to a load-bearing protective shell, and the bottom of the load-bearing protective shell is fixedly connected to a clamping head through a connecting wire, a heat dissipation hole is opened on one side of the load-bearing protective shell, the replacement mechanism is located on one side of the load-bearing protective shell, and the replacement mechanism includes a load-bearing bracket movably installed on one side of the load-bearing protective shell, and the inner side of the load-bearing bracket is fixedly connected to a dust-proof fiber net; by designing the dust-proof fiber net installed on the inner side of the load-bearing protective shell, dust-proof treatment of the fixed card block is achieved, which greatly reduces the entry of dust. At the same time, by designing the load-bearing bracket installed on the outside of the dust-proof fiber net, and under the tension of the expansion spring, convenient replacement and cleaning of the dust-proof fiber net is achieved, which solves the problem of poor dust-proof effect of the existing fixed card block.

[0004] Although the wiring device of the above patent is convenient for heat dissipation and dust prevention, it is easy for the debugging connection wires to be entangled on the outside of the device during electrical debugging, making it difficult to sort them out. It is easy for the connection wires to cross and entangle with each other, causing great inconvenience in sorting after use and increasing the workload. Therefore, it is necessary to design a wiring device for electrical debugging of subway vehicles to solve the above problems. Utility Model Content
