Description

一种挂车滑架 技术领域
本发明涉及商用车辆技术领域，具体涉及一种挂车滑架。
背景技术
滑架安装在挂车车架的大梁上，挂车的悬挂系统被安装在滑架上，滑架与挂车的大梁可活动的配合，也就是说，可调整滑架在挂车大梁长度方向的位置，继而调整挂车与牵引车之间的距离，从而使载荷能够合理分布，以此使挂车能够适应不同的路况。现有的滑架通常是由两根纵梁、多根横梁、以及用于安装悬挂系统的支架组成，纵梁与横梁连接处采用焊接的方式固定，支架焊接固定在纵梁上，因此，需要将纵梁和横梁预先焊接后，在通过物流将滑架送至总装厂与挂车进行组装，纵梁和横梁焊接后，由于其体积和重量较大，运输过程占用的空间相对较大，且难以进行搬运，导致滑架的运输成本较高。
发明内容
针对现有技术的不足，本发明的目的旨在于提供一种挂车滑架，其能够将纵梁和横梁分开运输，降低滑架的运输成本，同时可实现快速组装。
为实现上述目的，本发明采用如下技术方案：
一种挂车滑架，包括位于滑架两侧的两根纵梁、以及至少两根位于两纵梁之间的横梁；
纵梁包括侧壁、位于侧壁顶部的上连接壁、位于侧壁底部且与上连接壁相对的下连接壁；
横梁包括上连接板、位于上连接板下方且与上连接板相对的下连接板、位于上连接板和下连接板端部之间的端板；横梁的端部置于纵梁的上连接壁和下连接壁之间，上连接板贴靠在上连接壁下方、下连接板贴靠在下连接壁上方、端板贴靠在侧壁的内侧；
上连接板与上连接壁通过第一哈克螺栓连接、下连接板与下连接壁通过第二哈克螺栓连接、端板与侧壁通过第三哈克螺栓连接。
侧壁的顶部设置有一向内延伸的弯折部、由弯折部的内侧向下延伸的连接部，上连接壁由连接部的底部向内折弯而成，上连接壁的上方设置有一加强件，该加强件包括贴靠在上连接壁上表面的加强底板、由加强底板的一端向上折弯而成的加强筋板，加强筋板与纵梁的长度方向垂直，加强筋板的外侧边抵靠在连接部上并与连接部焊接固定，第一哈克螺栓的螺杆 由下至上依次穿过上连接板、上连接壁以及加强底板，该第一哈克螺栓的螺母压设在加强底板的上表面。
该挂车滑架还包括支架，包括位于纵梁外侧的外支架、以及位于外支架内侧的内支架，外支架和内支架之间形成一安装空间，外支架的顶部贴靠在侧壁的外表面，第三哈克螺栓的螺杆由内向外依次穿过端板、侧壁以及外支架的顶部，该第三哈克螺栓的螺母压设在外支架的外表面。
外支架的内侧焊接固定有一下支撑板，下连接壁上设置有一向上凸起且沿纵梁长度方向延伸的凸筋，下连接板置于凸筋顶部上方，下支撑板封盖在凸筋下方开口处，第二哈克螺栓的螺杆由上至下穿过上连接板、凸筋以及下支撑板，该第二哈克螺栓的螺母压设在下支撑板的下表面。
外支架上设置有一定位槽，纵梁上位于侧壁和下连接壁衔接的位置处形成一定位部，该定位部与定位槽配合形成一定位组件。
内支架包括两个侧板、以及位于两侧板之间的水平连接板，该水平连接板贴靠在横梁下连接板的下表面，水平连接板通过第四哈克螺栓连接在下连接板上。
横梁包括两个截面呈C形的连接梁，两连接梁的开口相对设置，每一个连接梁均包括上连接板、下连接板以及将上连接板和下连接板连接在一起的腹板；内支架的两个侧板分别贴靠在横梁的两腹板外侧，且腹板和侧板通过第五哈克螺栓连接。
连接梁内设置有一位于上连接板和下连接板之间的支撑件，该支撑件呈Z形，支撑件的顶部套设在第一哈克螺栓的螺杆上、底部套设在第四哈克螺栓的螺杆上。
本发明的有益效果在于：
本发明将纵梁设置为截面呈C形的结构，使横梁端部能够插入到纵梁中，横梁上的端板、上连接板、下连接板分别贴靠纵梁的侧壁、上连接壁和下连接壁，端板与侧壁、上连接板和上连接壁、下连接板和下连接壁分别通过哈克螺栓固定连接，如此，第三哈克螺栓沿滑架的宽度方向连接纵梁和横梁，第一哈克螺栓和第二哈克螺栓沿滑架的高度方向连接纵梁和横梁，由于采用免焊接的方式固定纵梁和横梁，使得纵梁和横梁能够分开运输，降低了运输成本，同时，可利用哈克螺栓将纵梁和横梁固定在一起，实现滑架的快速组装。

如图1、2、3、4所示，为本发明的一种挂车滑架，其包括两根纵梁10、以及两根横梁20，两根纵梁10分别位于滑架的两侧并沿滑架的长度方向延伸，两根横梁20沿滑架的宽度方向延伸并位于两根纵梁10之间，横梁20的两端分别与两纵梁10固定，以使滑架形成一个能够置于挂车车架上的框架结构。纵梁10采用板件折弯而成，从其横截面上来看，纵梁10包括侧壁11、位于侧壁11顶部的上连接壁12、以及位于侧壁11底部的下连接壁13，下连接壁13与上连接壁12相对设置，其二者均是由侧壁11向内侧弯折而成，由此，使纵梁10形成一个横截面呈开口向内侧的C形构造，横梁20的端部由内向外由纵梁10的C形开口穿入到纵梁10中，具体的，横梁20包括上连接板212、与上连接板212相对的下连接板213、以及位于上连接板212和下连接板213端部的端板23，在将横梁20插入到纵梁10中后，使横梁20的端部置于纵梁10的上连接壁12和下连接壁13之间，上连接板212贴靠在上连接壁12的下表面，下连接板213贴靠在下连接壁13的上表面，同时端板23贴靠在侧壁11的内侧表面，在组装时，沿滑架宽度方向将横梁20插入纵梁10，端板23与侧壁11贴靠时，说明横梁20与纵梁10配合到位。上述的上连接板212与上连接壁12通过第一哈克螺栓50固定在一起，下连接板213与下连接壁23通过第二哈克螺栓90固定连接在一起，端板23与侧壁11通过第三哈克螺栓40固定连接在一起，以此，将横梁20与纵梁10固定连接。
本发明中，将纵梁10设置为截面呈C形的结构，使横梁20端部能够插入到纵梁10中，横梁20上的端板23、上连接板212、下连接板213分别贴靠纵梁10的侧壁11、上连接壁12和下连接壁13，端板23与侧壁11、上连接板212和上连接壁12、下连接板213和下连接壁13分别通过哈克螺栓固定连接，如此，第三哈克螺栓沿滑架的宽度方向连接纵梁10和横梁20，第一哈克螺栓和第二哈克螺栓沿滑架的高度方向连接纵梁10和横梁20，由于采用免焊接的方式固定纵梁10和横梁20，使得纵梁10和横梁20能够分开运输，降低了运输成本，同时，可利用哈克螺栓将纵梁10和横梁20固定在一起，实现滑架的快速组装。
需要说明的是，本发明的滑架不限于是包括两根横梁20，其还可以在两纵梁10之间设置三个或三个以上的横梁20。
在优选实施例中，本发明在侧壁11的顶部还设置有一向着内侧延伸的弯折部111、以及由弯折部111的内侧向下延伸的连接部112，也就是说，将侧壁11向内折弯90°，形成水平的弯折部111，再将弯折部111向下折弯形成竖向的连接部112，上连接壁12是由连接部112向内侧折弯形成，上连接壁12呈水平状态，能够较好的贴合横梁20的上连接板212的上表面，由于上连接壁12为悬空构造，在上连接壁12的与横梁20配合的位置上方，还设置有一加强件，该加强件固定在上连接壁12的上方，其包括贴靠在上连接壁12上表面的加强底板14、以及由加强底板14的一端向上折弯而成的加强筋板15，加强底板14用于使上连接壁12上与横梁20连接的位置厚度增大，加强筋板15与纵梁10的长度方向垂直，其外侧边抵靠在连接部112上并与连接部112焊接固定，通过加强筋板15在连接部112和上连接壁12之间加强，避免上连接壁12与连接部112衔接处发生形变。上述的第一哈克螺栓50的螺杆由下至上依次穿过上连接板212、上连接壁12、加强底板14，第一哈克螺栓50的螺母51压设在加强底板14的上表面，利用上述的加强件在上连接壁12与横梁20配合的位置处对纵梁10进行加强，同时第一哈克螺栓50穿接在加强件上，确保上连接壁12与横梁20连接配合处具有较佳的连接强度。
在另一个优选实施例中，本发明的挂车滑架还包括支架，支架用于安装车辆的悬挂系统，为了进一步便于滑架的运输，支架同样是采用哈克螺栓与纵梁10、横梁20固定连接，具体的，支架包括位于纵梁10外侧的外支架31、以及位于外支架31内侧并与外支架31相对设置的内支架32，内支架32与外支架31之间形成一安装间隙，以适用于悬挂系统的组装，外支架31的顶部贴靠在侧壁11的外表面，上述的第三哈克螺栓40的螺栓由内向外依次穿过端板23、侧壁11以及外支架31的顶部，第三哈克螺栓40的螺母41压设在外支架31的外表面，即利第三哈克螺栓40将端板23、侧壁11和外支架31三者同时固定连接在一起，当然，为了确保稳定性，并且由于端板23能够在横梁20的端部提供一个较大的安装面积，可以是利用多个第三哈克螺栓40连接端板23、侧壁11和外支架31。外支架31上设置有一定位槽311，纵梁10上位于侧壁11和下连接壁13衔接的位置处形成一个定位部，定位部与定位槽311配合形成一个定位组件，用于在装配时，对外支架31和纵梁10进行定位，可以是在外支架31上通过一道折弯结构形成上述的定位槽311，其折弯的形状恰好与纵梁10上侧壁11和下连接壁13衔接处的弧形倒角的形状一致，以便于外支架31在于纵梁10装配时，使外支架31能够与纵梁10精准对位，以便于第三哈克螺栓40的螺杆能够顺利的从端板23、侧壁11和外支架31，从而提高组装的效率。内支架32包括两个侧板321、以及水平连接板322，两侧板321沿滑架的长度方向排列并相对设置，水平连接板322位于两侧板321之间，该水 平连接板322贴靠在横梁20下连接板213的下表面，水平连接板322通过第四哈克螺栓80连接在下连接板213上。为了保证横梁20自身的强度，同时确保内支架32、纵梁10与横梁20的连接强度，本发明的横梁20包括连接梁21和连接梁22，连接梁21和连接梁22的结构相同，其二者的截面均呈C形，且连接梁21和连接梁22的C形开口相对，连接梁21和连接梁22均包括上连接板212、下连接板213以及将上连接板212和下连接板213连接在一起的腹板211，端板23焊接在连接梁21和连接梁22的端部以组成一个整体的横梁20，内支架32的两侧板321分别贴靠在连接梁21和连接梁22腹板211的外侧，并且两侧板321分别通过第五哈克螺栓70连接在两腹板211上。上述的水平连接板322分别通过一个第四哈克螺栓80固定在连接梁21和连接梁22的下连接板213上；在横梁20的端部处，连接梁21和连接梁22的下连接板213分别通过一个第二哈克螺栓90连接在下连接壁13上，连接梁21和连接梁22的上连接板212分别通过一个第一哈克螺栓50连接在上连接壁12上。此外，在连接梁21内还设置有一位于上连接板212和下连接板213支架的支撑件24，该支撑件24呈Z形，支撑件24的顶部套设在第一哈克螺栓50的螺杆上、底部套设在第四哈克螺栓80的螺杆上，通过该支撑件24在连接梁21内部对连接梁21进行加强，组装时，第一哈克螺栓50的螺杆由下至上依次穿过支撑件24的顶部、上连接板212、上连接壁12以及加强底板14，第四哈克螺栓80的螺杆由上至下依次穿过支撑件24的底部、下连接板213、水平连接板322，也可以是在上述连接梁22同样设置一个支撑件24，其连接结构与上述相同，在这里不做重复描述。
此外，在下连接壁13上设置有一向上凸起的凸筋131，该凸筋131沿纵梁10的长度方向延伸，通过该凸筋131可增加下连接壁13的纵向抗弯曲强度，同时，横梁20在插入纵梁10后，横梁20的下连接板213置于凸筋131的顶部上方，下连接壁13的下方设置有一封盖在凸筋131下方开口处的下支撑板16，该下支撑板16预先焊接固定在外支架31的内侧，第二哈克螺栓90的螺杆由上至下穿过下连接板213、凸筋131、下支撑板16，第二哈克螺栓90的螺母91压设在下支撑板16的下表面，通过旋紧第二哈克螺栓90的螺母91，使螺母91充分压紧下支撑板16，由于凸筋131与下支撑板16之间存在一定的间隙，在拧紧螺母91时，可使凸筋131发生轻微的变形，变形的凸筋131对螺母91产生一定的预紧力，使下连接板213、下连接壁13连接处形成紧配合的连接结构，从而确保该处具有较佳的连接强度。
参见图5，本发明的滑架可安装空气悬挂系统，空气悬挂系统可以是通过上述的支架安装在滑架上。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发 明进行了详细的说明，本领域的普通技术人员应当理解，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
