Description

Technical Field

[0001] The utility model relates to the field of wall-mounted brackets, in particular to a shield interval wall-mounted signal machine bracket. Background Technique

[0002] At present, in signal engineering, the installation of shield interval wall-mounted signal machine brackets generally adopts the method of installing signal machines and box boxes on a wall-mounted integrated platform. The specific construction method is to complete the point determination and measurement of signal machine equipment in the shield interval. According to the design requirement that the installation height of the signal machine bracket is 1 meter from the top surface of the rail, the standard line height of the top surface of the wall-mounted integrated platform is determined. The construction personnel closely attach the wall-mounted integrated platform to the shield segment and its standard line height, mark the punching positions of the stainless steel expansion bolts of the wall-mounted integrated platform, complete the punching, explosion-proofing and installation of the wall-mounted integrated platform, and complete the installation of the signal machine and box boxes. This construction method requires 6 people to complete the handling and installation of the wall-mounted integrated platform, signal machine and box boxes, and it takes 2 hours to complete the installation of 1 signal machine and box box, increasing the labor cost of signal machine and box box installation; due to the excessive weight of the wall-mounted integrated platform, there are great safety risks during the handling process.

[0003] During the process of installing the chilled water pipe on the weak current side of the track area, one of the technical challenges is to ensure the coordinated installation of various equipment, especially when the large-diameter chilled water pipe shares the limited space with the signal system. Due to its large self-weight and thick diameter, the installation of the chilled water pipe not only requires a stable support system, but also needs to consider the optimization of the space layout to avoid interfering with other equipment. Specifically, the installation height of the signal machine is one of the key factors to ensure train operation safety, which directly affects the driver's recognition and response speed to the signal. However, in actual construction, the position conflict between the chilled water pipe and the signal machine in the track area may cause the signal machine bracket tray to tilt. In order to accommodate the chilled water pipe and the support system, the installation height of the signal machine sometimes has to be adjusted, resulting in a reduction in the originally designed standard installation height. This change is directly related to the levelness of the signal machine bracket tray. The non-level signal machine bracket tray may cause a series of problems. First of all, it will affect the stability and reliability of the signal machine, increasing the risk of signal machine deviation caused by vibration or external force. Secondly, the non-level tray may also cause the signal display angle of the signal machine to deviate, affecting the driver's line of sight, and thus reducing the overall safety of the signal system. In addition, the long-term unbalanced state may also accelerate the wear of the bracket and the signal machine itself, shortening the service life.

[0004] Therefore, when installing chilled water pipes on the weak current side of the track area, how to balance the requirements of stable installation of chilled water pipes and safe and efficient operation of signal machines, and prevent the signal machine support tray from tilting due to the position conflict between the chilled water pipes in the track area and the signal machine has become a technical problem to be solved urgently. This requires the construction team to fully consider the spatial layout in the design stage, adopt a scientific and reasonable support design scheme, ensure the reasonable installation of signal machines and chilled water pipes in the track area, prevent the problem of signal machine support tray tilting caused by position conflict, and still maintain the levelness of the support tray after adjusting the installation height, so as to ensure the stable operation of the entire signal system and train operation safety. In addition, due to the excessive weight of the wall-mounted integrated platform, the labor cost of installing signal machines and boxes will be greatly increased during the installation process, and there are great safety risks during the handling process. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art, such as the high labor cost of installing signal machines and boxes, and the tilting of the signal machine support tray caused by the position conflict between the chilled water pipes in the track area and the signal machine, and to provide a wall-mounted signal machine support for the shield section. This method is quick to install, has high efficiency, reduces the labor cost of manual handling and installing the wall-mounted integrated platform, and solves the problem that the installation height of the signal machine is reduced when installing chilled water pipes on the weak current side of the track area, resulting in the unevenness of the signal machine support tray.

[0006] In order to achieve the above invention purpose, the present invention provides the following technical solutions:
