具体实施方式Detailed ways
轨道车辆通常由首尾相连的多节车厢组成，车厢包括车体，车体的一端设有电器柜，电器柜内设有多种高压电气设备和控制设备，以满足车辆的配电和列车运行控制的需求。由于电器柜内设有多种高压电气设备和控制设备，在工作时存在一定的易燃风险，因此电器柜本身需要具备一定的防火能力。为解决该问题，在相关技术的方案中，一般将电器柜选用防火板制成，并在电器柜内侧的防火板上喷涂防火漆或粘贴不锈钢板以进一步防火。Rail vehicles are usually composed of multiple carriages connected end-to-end. The carriage includes a car body. One end of the car body is provided with an electrical cabinet. The electrical cabinet is equipped with a variety of high-voltage electrical equipment and control equipment to meet the power distribution and train operation control of the vehicle. demand. Since there are a variety of high-voltage electrical equipment and control equipment in the electrical cabinet, there is a certain risk of flammability during work, so the electrical cabinet itself needs to have a certain fire resistance. In order to solve this problem, in the solution of the related art, the electrical cabinet is generally made of fireproof board, and the fireproof board inside the electrical cabinet is sprayed with fireproof paint or pasted with stainless steel plate to further prevent fire.
但是，由于防火板的密度较大，选用防火板制成的电器柜柜体重量较重。若后续采用在电器柜柜体内侧粘贴不锈钢板的方案会进一步增加电器柜的整体重量；若后续采用在电器柜柜体内侧喷涂防火漆的方案，防火漆在遇明火后会产生大量的有害气体，不利于乘客的身体健康。However, due to the high density of the fireproof board, the weight of the electrical cabinet made of the fireproof board is heavier. If the scheme of pasting the stainless steel plate on the inside of the electrical cabinet is adopted in the future, the overall weight of the electrical cabinet will be further increased; if the scheme of spraying fire retardant paint on the inside of the electrical cabinet cabinet is adopted subsequently, the fire retardant paint will produce a large amount of harmful gas when exposed to an open flame. , is not conducive to the health of passengers.
有鉴于此，本申请实施例旨在提供一种在保证防火柜防火能力的前提下质量较轻且较环保的车厢及具有该车厢的轨道车辆。In view of this, the embodiments of the present application aim to provide a light-weight and environmentally friendly carriage and a rail vehicle having the carriage on the premise of ensuring the fireproof capability of the fireproof cabinet.
为了使本申请实施例中的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。In order to make the technical solutions and advantages of the embodiments of the present application more clear, the exemplary embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and Not all embodiments are exhaustive. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.
实施例一Example 1
图1中示出的是本申请一实施例提供的车厢的结构简图；图2中示出的是本申请一实施例提供的防火柜的结构简图；图3中示出的是本申请一实施例提供的耐火复合板的截面图；请参照图1-图3。Figure 1 shows a schematic structural diagram of a carriage provided by an embodiment of the present application; Figure 2 shows a schematic structural diagram of a fireproof cabinet provided by an embodiment of the present application; Figure 3 shows the present application A cross-sectional view of the refractory composite panel provided by an embodiment; please refer to FIGS. 1-3 .
本实施例提供一种车厢，包括车体10。车体10包括相邻的第一侧壁110和第二侧壁120，其中，车体10大体呈长方体状，图1中第一侧壁110为沿车体10宽度方向的侧壁，第二侧壁120为沿车体长度方向的侧壁。车体10内设有电器柜(图中未示出)，电器柜位于第一侧壁110和第二侧壁120的连接处；也即，电器柜的柜体的两侧分别抵接在第一侧壁110和第二侧壁120上。一般的，电器柜大体也呈长方体状，其内部形成有用于容纳其他设备的容纳腔，车厢内的高压电器设备和控制设备等大都收容在该容纳腔内。This embodiment provides a carriage including a vehicle body 10 . The vehicle body 10 includes adjacent first side walls 110 and second side walls 120, wherein the vehicle body 10 is generally in the shape of a cuboid. In FIG. 1, the first side wall 110 is a side wall along the width direction of the vehicle body 10, and the second The side wall 120 is a side wall along the longitudinal direction of the vehicle body. The vehicle body 10 is provided with an electrical cabinet (not shown in the figure), and the electrical cabinet is located at the junction of the first side wall 110 and the second side wall 120; on one side wall 110 and the second side wall 120 . Generally, the electrical cabinet is also generally in the shape of a cuboid, and an accommodating cavity for accommodating other equipment is formed in the interior. Most of the high-voltage electrical equipment and control equipment in the compartment are accommodated in the accommodating cavity.
由于电器柜内容纳了大量的电器设备，因此在列车运行时，电器柜内部存在因短路等原因而造成的起火风险，为防止火势蔓延到车厢内的其他区域，在车体10内还设有防火柜20，防火柜20连接车体10且罩设在电器柜的外侧；也即防火柜20和车体10共同围成用于容纳电器柜的腔室，电器柜被收容在该腔室内从而与外部环境相对隔离。Since a large number of electrical equipments are contained in the electrical cabinet, there is a risk of fire caused by short circuit and other reasons inside the electrical cabinet when the train is running. The fireproof cabinet 20 is connected to the vehicle body 10 and is covered outside the electrical cabinet; that is, the fireproof cabinet 20 and the vehicle body 10 together form a chamber for accommodating the electrical cabinet, and the electrical cabinet is accommodated in the chamber so as to Relative isolation from the external environment.
具体的，防火柜20的上端可以连接在车体10内的顶板(图中未示出)，防火柜20的下端可以连接在车体10的地板上，防火柜的侧面的两端分别连接在第一侧壁110和第二侧壁120上，也就是说，本实施例中防火柜20只需要将电器柜的两个相邻的侧壁遮蔽住即可，其他部分的防火可用车体10来实现，由此，使得本实施例防火柜20所需的材料要大大小于已有技术中电器柜 所需的材料(因已有技术中电器柜的六个面均需要用防火材料制备，而本申请只需要最多制备两个侧面即可)；并且可以在不改变普通无防火功能的电器柜结构的基础上实现车厢内的电器防火功能(只需在普通电器柜的外侧增加本实施例的防火柜20即可)，便于对车厢的升级改造。本实施例中防火柜20的结构可根据需要进行设置，例如可以参照车体10设置为两个相连的侧壁，或者，也可以设置成一个横截面呈圆弧状的侧壁。Specifically, the upper end of the fireproof cabinet 20 can be connected to the top plate (not shown in the figure) in the vehicle body 10, the lower end of the fireproof cabinet 20 can be connected to the floor of the vehicle body 10, and the two ends of the side of the fireproof cabinet are respectively connected to On the first side wall 110 and the second side wall 120, that is to say, in this embodiment, the fireproof cabinet 20 only needs to cover the two adjacent side walls of the electrical cabinet, and other parts of the fireproof can be protected by the vehicle body 10. Therefore, the material required for the fireproof cabinet 20 in this embodiment is much smaller than the material required for the electrical cabinet in the prior art (because the six surfaces of the electrical cabinet in the prior art all need to be prepared with fireproof materials, and The application only needs to prepare at most two sides); and the fireproof function of electrical appliances in the compartment can be realized without changing the structure of ordinary electrical cabinets without fireproof function (only need to increase the outer side of the ordinary electrical cabinets in this embodiment. The fireproof cabinet 20 is sufficient), which is convenient for the upgrading and transformation of the carriage. The structure of the fireproof cabinet 20 in this embodiment can be set as required, for example, it can be set as two connected side walls with reference to the vehicle body 10 , or can also be set as one side wall with an arc-shaped cross section.
进一步地，本实施例中的防火柜20为耐火复合板防火柜，也即，防火柜20由耐火复合板制成。如图3所示，耐火复合板30包括层叠设置的防火板310、第一铝板320、轻芯刚板330和第二铝板340，其中，防火板310设置在背离电器柜的一侧，也即朝向乘客的一侧；并且轻芯钢板330占据了耐火复合板70％以上的体积，从而使得同样体积下耐火复合板30相比于相关技术中采用实心结构的防火板310质量更轻。此外，在朝向电器柜的一侧，本实施例中贴合了第二铝板340，铝板相较于钢板的质量更轻，并且在遇火时不会燃烧产生有毒有害的气体，更加环保健康。Further, the fireproof cabinet 20 in this embodiment is a fireproof composite board fireproof cabinet, that is, the fireproof cabinet 20 is made of a fireproof composite board. As shown in FIG. 3 , the refractory composite board 30 includes a fireproof board 310 , a first aluminum board 320 , a light core rigid board 330 and a second aluminum board 340 arranged in layers, wherein the fireproof board 310 is arranged on the side away from the electrical cabinet, that is, The light-core steel plate 330 occupies more than 70% of the volume of the refractory composite panel, so that the refractory composite panel 30 is lighter in weight than the solid structure fireproof panel 310 in the related art under the same volume. In addition, on the side facing the electrical cabinet, in this embodiment, a second aluminum plate 340 is attached. The aluminum plate is lighter in weight than the steel plate, and will not burn to produce toxic and harmful gases in case of fire, which is more environmentally friendly and healthy.
第二铝板340朝向电器柜的一侧可设有白色涂层，白色涂层在遇到火后会留下黑色印记，从而便于工作人员查找故障的具***置。The side of the second aluminum plate 340 facing the electrical cabinet may be provided with a white coating, and the white coating will leave a black mark after encountering a fire, so as to facilitate the staff to find the specific location of the fault.
需要说明的是，由于无需选用耐火材料制备的电器柜，电器柜可采用普通金属制成，大大减轻了电器柜的重量；并且电器柜与耐火复合板制成的防火柜30的总体重量扔远小于全部采用实心耐火板制成的电器柜的重量。It should be noted that, since there is no need to select an electrical cabinet made of refractory materials, the electrical cabinet can be made of ordinary metal, which greatly reduces the weight of the electrical cabinet; and the overall weight of the electrical cabinet and the fireproof cabinet 30 made of refractory composite panels is far away Less than the weight of an electrical cabinet made entirely of solid refractory panels.
通过上述描述可知，本实施例由于在电器柜的外侧设置了防火柜20，防火柜20与车体10连接后罩设在电器柜的外侧，因此可以将电器柜与外界相隔离，实现防火功能；并且，相比于相关技术中的方案，本实施例还能够减轻车厢的整体重量且更加环保。As can be seen from the above description, in this embodiment, the fireproof cabinet 20 is arranged on the outer side of the electrical cabinet, and after the fireproof cabinet 20 is connected with the vehicle body 10, the cover is arranged on the outer side of the electrical cabinet, so the electrical cabinet can be isolated from the outside world to realize the fireproof function. Moreover, compared with the solutions in the related art, the present embodiment can also reduce the overall weight of the carriage and is more environmentally friendly.
