Description

Technical Field

[0001] The invention relates to an interior component of a rail vehicle, in particular to a protective device for a brake pull rod. Background Art

[0002] In previous subway and urban rail vehicle projects, the brake lever was placed under the seat and protected by a cover. The brake lever cover is a separate internal component, and there is no need to consider the installation interface during installation. This cover only needs to prevent the brake lever from being operated by non-staff and ensure the installation strength, without considering the bearing strength of the cover itself.

[0003] Since the vehicle formation and model of the Boston project in the United States are different from conventional models, it is a formation of 2 vehicles / train, divided into driver cab vehicles and non-driver cab vehicles. There is only an open simple operation driver's desk at the front of the non-driver cab vehicle, and the brake lever is on the passenger compartment side of the simple operation driver's desk. The space at this location is limited and seats cannot be arranged, so the protective cover of the brake lever has to be exposed. In addition, there is an inspection door on the side of the brake lever near the simple operation platform, which also needs to be inspected. Therefore, it is necessary to develop a new type of brake lever protection device that can meet the operation requirements of the brake lever device, the maintenance space requirements of electrical equipment, its own strength requirements, and the installation strength requirements. Summary of the invention

[0004] The purpose of the present invention is to develop a new type of brake rod protection device, which not only meets the protection and operating space requirements of the brake rod, but also meets the maintenance space requirements of the electrical equipment inside the driver's station for simple operation.

[0005] In order to achieve the above-mentioned purpose of the invention, the present invention provides a protective device for a brake rod, characterized in that: the lower wall panel at the brake rod is an integral fiberglass cover shell, which is composed of a front panel and side panels on both sides, the front panel is a multi-radius and multi-curve transition structure, the upper half of the side panel is arc-shaped, and the lower half is trapezoidal, the side panel is narrow at the upper part and wide at the lower part, the curvature of the rear edge of the side panel is consistent with the side wall of the vehicle body, the front panel is shorter than the side panel, and a curved inspection door is provided at the opening formed by the front panel and the two side panels.

[0006] An aluminum profile frame is provided at the middle and upper part of the back side of the side panel to ensure the strength of the entire lower wall panel.

[0007] The aluminum profile frame is provided with a stainless steel mounting seat for mechanical installation with the vehicle body side wall.

[0008] A reinforcing beam is provided at the middle and lower part of the back side of the side plate to improve the strength of the entire lower wall plate.

[0009] The upper part of the back side of the side panel is provided with a nylon buckle for buckle connection with the wall panel of the window area.

[0010] A support pad is provided at a position on the back of the side plate where there is no installation space, and is used for contacting and supporting the pre-installed transition beam.

[0011] The bottoms of the two side plates are both in the shape of relatively inwardly bent steps, which are plugged into and matched with the inspection door.

[0012] The present invention uses a special integral fiberglass cover shell structural shape design and an inspection door provided at the opening, so that the portion of the brake rod exposed to the ground is covered by the fiberglass cover shell and locked and protected by the inspection door. The multi-rounded and multi-arc transition structure of the fiberglass cover shell provides ample operating space for the brake rod. At the same time, the design of the fiberglass cover shell that gradually narrows from bottom to top facilitates the maintenance operation of electrical components in the simple driver's station.

[0013] The advantages and improvements of the present invention over the prior art are as follows:

[0014] 1) The device has multiple rounded corners and arcs, which increases the operating space of the brake lever and facilitates the maintenance of electrical components in the simple driver's station. At the same time, due to the non-flat design, it avoids the deformation and damage of the wall panel caused by passengers placing heavy objects or stepping on it.

[0015] 2) The inspection door of this device has a large operating space and is easy to install and disassemble. It is suitable for urban rail and high-speed rail projects with limited space and leaky protective covers.

[0016] 3) The device itself has high strength and is firmly installed to prevent damage by passengers. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 1 , Figure 3The whole device is mainly composed of a glass fiber reinforced plastic shell 1 and an inspection door 2. The glass fiber reinforced plastic shell is divided into two parts: a front plate 101 and a side plate 102. The front plate 101 is a transition structure with multiple rounded corners and multiple arcs. The upper half of the side plate 102 is arc-shaped, and the lower half is trapezoidal. The side plate is narrow at the top and wide at the bottom. The arc of the rear edge of the side plate matches the side wall of the vehicle body. The front plate is shorter than the side plate. A curved inspection door 2 is provided at the opening formed by the front plate and the two side plates. The lower part between the glass fiber reinforced plastic shell 1 and the inspection door 2 adopts a plug-in structure, and the upper part uses two compression locks 3 and is equipped with an aluminum alloy buckle 4, so that the inspection door 2 can be opened and locked when the brake lever is operated.

[0022] Reference Figure 2 , Figure 4 The aluminum profile frame 8 and the reinforcing beam 9 are pasted on the back of the side panel 102 to ensure the strength of the entire FRP cover structure; the aluminum profile frame 8 is provided with a stainless steel mounting seat 7, the upper part of the FRP cover 1 is installed with the window area wall panel by nylon buckle 6, the side is mechanically installed with the side wall of the vehicle body through the stainless steel mounting seat 7, and the position without installation space is supported by the support pad 5 and the pre-installed transition beam; the bottom is mechanically installed with the interior floor to ensure the installation strength of the entire FRP cover structure. The bottoms of the two side panels 102 are both relatively inwardly bent step shapes, which are plugged into the inspection door.
