Problems solved by technology
Specifically, the temperature-sensing cables in the prior art are welded to the vehicle frame with fixing seats and connected by bolts. Due to the large number of fixing seats, the installation workload of the temperature-sensing cables also increases.
And if a fault occurs, it is impossible to disassemble and replace the temperature-sensing cable without disassembling the power pack and pipeline. In case of a fault, it is necessary to disassemble the power pack and pipeline, and then disassemble the temperature-sensing cable. The workload is huge, and the maintenance cycle and cost higher
[0004] To sum up, there are many fixing seats in the installation of power pack temperature-sensing cables in the prior art; the installation of the fixing seats is difficult and unsightly; the temperature-sensing cables cannot be directly disassembled; the maintenance cycle and high cost seem to be problems

The invention discloses a temperature-sensing cable fixing device and a vehicle chassis, the temperature-sensing cable fixing device comprises a strip-shaped base, fixing strips for installing an inner-layer temperature-sensing cable and an outer-layer temperature-sensing cable are arranged along the length direction of the strip-shaped base, a plurality of locking mechanisms are arranged on the fixing strips, and the locking mechanisms on the two fixing strips are arranged in a staggered manner. The temperature sensing cable fixing device is fixed to the inner wall where the power pack maintenance opening is located through the strip-shaped base of the temperature sensing cable fixing device, and the temperature sensing cable fixing device is arranged along the power pack maintenance opening. The temperature sensing cable can be directly detached without detaching the power pack, and the fixing frame which is of an integrated double-layer structure and easy to install and detach is adopted. A reasonable temperature sensing cable layout structure is designed according to the characteristics of a power pack maintenance port, and direct disassembly and maintenance are facilitated.
Description
technical field [0001] The invention relates to the technical field of vehicle design, in particular to a temperature-sensing cable fixing device and a vehicle underframe using the temperature-sensing cable fixing device. Background technique [0002] Since the power pack of the urban rail vehicle is a high-risk area prone to fire, it has high reliability requirements for the fire alarm performance of the power pack, so it is necessary to use a dual redundant temperature-sensing cable configuration. This configuration puts forward higher requirements on the frame structure and installation space. [0003] In the prior art, there are a large number of heat-sensing cable fixing seats in the power pack, which are scattered and difficult to install. In addition, the dual redundancy requirements of the temperature-sensing cables greatly increase the difficulty of installation, and the temperature-sensing cables cannot be directly disassembled. Specifically, the temperature-sensi...
