Description

Technical Field

[0001] This utility model relates to the field of electrical component installation technology, specifically to a vibration-proof installation device for electrical components in subway vehicles. Background Technology

[0002] As the core transportation tool of urban rail transit, the operation of subway vehicles relies on a complex and highly integrated electrical system. This system consists of a variety of electrical components and is responsible for key tasks such as traction, braking, control, power supply, signal transmission, safety monitoring and auxiliary functions. The electrical components are usually installed in electrical boxes located at the bottom of the car body or in the passenger compartment to achieve physical protection and electromagnetic shielding. The electrical boxes protect the electrical components and prevent them from vibrating during vehicle operation.

[0003] As electrical boxes house various electrical components, the traditional installation method for electrical components generally involves welding fixed metal brackets inside the electrical box and then rigidly connecting the electrical components to the brackets with bolts. Different motor components have different sizes, but the welded brackets are one-time molded structures with fixed positions and sizes, making it difficult to adapt to electrical components of different sizes. This results in a situation where the upper space is idle while the lower space is crowded, thus causing a waste of resources. To address this, we propose a vibration-proof installation device for electrical components in subway vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration-proof installation device for electrical components of subway vehicles to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-proof installation device for electrical components of subway vehicles, comprising: a housing and a cover, the cover being connected to the housing, and the housing and the cover working together to protect the electrical components inside the housing; Also includes: The enclosure consists of two vertical supports and several horizontal supports. The two vertical supports are connected to both sides of the inner wall of the enclosure. The several horizontal supports are located between the two vertical supports and are connected to the vertical supports. Each horizontal support has a sliding groove, and each vertical support has a sliding plate connected to it. The sliding plate is slidably connected to the sliding groove. Each vertical support has a fixing groove. When installing electrical components of different sizes, the sliding plate and the sliding groove are used together to adjust the distance between the horizontal supports. Each horizontal support has a fixing member connected to both ends, and the fixing member is connected to the fixing groove.

[0006] The fastener includes two fixing plates, which are respectively connected to both sides of the horizontal support.

[0007] The fixing plate is connected to a fixing column, and the fixing column corresponds to the fixing groove.

[0008] The fixing plate is connected to a fixing ring, which corresponds to the connecting hole, and the fixing ring has a snap-fit ​​groove.

[0009] The fixed column is connected to a snap-fit ​​column, and the snap-fit ​​column is snapped into the snap-fit ​​groove.

[0010] The horizontal support has a second sliding groove, a sliding plate is connected inside the second sliding groove, a fixing hole is provided on the sliding plate, and an installation plate is provided on the sliding plate.

[0011] The fixing hole is threaded to the mounting plate.

[0012] The sliding plate is equipped with hooks, which are threadedly connected to the fixing holes.

[0013] This utility model has at least the following beneficial effects: By setting two vertical supports and several horizontal supports, the two vertical supports are connected to both sides of the inner wall of the box, and several horizontal supports are all set between the two vertical supports and connected to the vertical supports. A sliding groove is opened on the horizontal support, and a sliding plate is connected to the vertical support. The sliding plate is slidably connected to the sliding groove. The sliding plate is inserted into the sliding groove and slidably cooperates with it, so that the horizontal support can move up and down along the vertical support in the vertical direction, thereby adjusting the distance between adjacent horizontal supports. A fixing groove is opened on the vertical support. When electrical components of different sizes are installed, the sliding plate and the sliding groove are used together to adjust the distance between the horizontal supports. Fixing parts are connected to both ends of the horizontal support. The fastener connects to the fixing slot, locking the transverse bracket to the corresponding height of the fixing slot. This ensures the transverse bracket is fixed in position, guaranteeing the overall structure is stable and reliable. It allows for flexible adjustment and secure locking of the installation height. When different sizes or quantities of electrical components need to be installed, the distance between adjacent transverse brackets can be adjusted to accommodate different sizes of electrical components. After adjustment, the fastener locks the transverse bracket in the target position, ensuring it will not shift due to vibration during vehicle operation. This allows for stepless or stepped adjustment of the transverse bracket height, greatly improving the device's adaptability to different types of electrical components, increasing the utilization rate of the electrical box's internal space, and facilitating modular layout and future expansion and upgrades.
