该两铰轴机构 23分别对称设置在该脖颈座 22的两纵向支架 221上，每一铰轴机构 23 包括两铰轴支架 231以及垂直横穿在该两铰轴支架 231近底端的一铰轴 232， 该两铰轴支 架 231的上半部夹持固定在该纵向支架 221的两侧， 该后部车身 1的纵梁 1 1前端的挂钩 挂在该铰轴 232上， 从而使得该铰轴机构 23通过该铰轴 232与该后部车身 1的前端相铰 接，以使所述铰接装置 2可相对所述后部车身 1上下转动地连接于所述后部车身 1的前端， 且使得该斜向支承平面 221 1位于该后部车身 1的上方。挂车正常行驶时，该铰轴支架 231 为竖直方向， 此时在该斜向支承平面 221 1与该后部车身 1的上表面之间形成一个三角区 域。 当需要从该后部车身 1的前端装卸货物时， 也可将该后部车身 1的前端的挂钩从该铰 轴 232上脱开， 以移开该后部车身 1进行货物的装卸。 The two hinged shaft mechanisms 23 are symmetrically disposed on the two longitudinal brackets 221 of the neck seat 22, and each hinge mechanism 23 includes two hinge brackets 231 and a hinge shaft vertically crossing the bottom end of the two hinge brackets 231. 232, the upper half of the two hinge brackets 231 are clamped and fixed on two sides of the longitudinal bracket 221, and the hook of the front end of the longitudinal beam 1 1 of the rear body 1 is hung on the hinge shaft 232, so that the hinge shaft The mechanism 23 is hinged to the front end of the rear body 1 through the hinge shaft 232 such that the hinge device 2 is rotatably coupled to the front end of the rear body 1 with respect to the rear body 1 and An oblique support plane 221 1 is located above the rear body 1 . When the trailer is running normally, the hinge bracket 231 is in a vertical direction, and a triangular area is formed between the oblique support plane 221 1 and the upper surface of the rear body 1. When it is necessary to load and unload the cargo from the front end of the rear body 1, the hook of the front end of the rear body 1 can be disengaged from the hinge shaft 232 to remove the rear body 1 for loading and unloading of the cargo.
该三角中位垫铁 24大小适配地活动插设在该斜向支承平面 221 1与该后部车身 1的上 表面之间的三角区域内并支承该纵向支架 221。 The triangular intermediate horn 24 is movably inserted in a triangular region between the oblique support plane 221 1 and the upper surface of the rear body 1 and supports the longitudinal bracket 221.
该顶升机构 3作用在该后部车身 1的两纵梁 1 1之间位于该颈脖座 22的横向支架 222 下方的该横梁 12上， 可以仅仅对应该横梁 12的中部位置作用一个该顶升机构 3， 为了更 好的受力，也可在该横梁 12的两侧位置分别作用一个该顶升机构 3 ,该顶升机构 3可向上 方顶动并支承该横向支架 222，进而使得该脖颈座 22以该铰轴 232中心逆时针旋转脱离该 三角中位垫铁 24的支承， 此时可将该三角中位垫铁 24转出或取出。 该顶升机构 3可以为 一机械顶升机构及与之配套的锁止机构， 也可为动力油缸及与之配套的液压锁（请参照图 6) 或其他可实现顶升锁止操作的机构。 The jacking mechanism 3 acts on the cross member 12 between the two longitudinal beams 11 of the rear body 1 below the transverse bracket 222 of the neck base 22, and the top portion of the cross member 12 can be applied only to the middle position of the cross member 12. The lifting mechanism 3, for better stress, may also respectively apply a lifting mechanism 3 on both sides of the beam 12, the jacking mechanism 3 can push up and support the lateral bracket 222, thereby making the The neck seat 22 is rotated counterclockwise from the center of the hinge shaft 232 The support of the triangular intermediate horn 24, at which point the triangular intermediate horn 24 can be rotated out or taken out. The jacking mechanism 3 can be a mechanical jacking mechanism and a locking mechanism matched thereto, and can also be a power cylinder and a hydraulic lock matched thereto (please refer to FIG. 6) or other mechanism capable of lifting the lock operation. .
所述前部车身 6包括沿挂车车体长度方向延伸的两纵梁 63以及垂直连接在该两纵梁 63之间的多根横梁 62。在所述前部车身 6底部还设有牵引销及销板总成 5，用于与挂车前 方的动力牵引机构相连接， 其结构与该部分的通常结构类似， 在此不再详细描述。 The front body 6 includes two longitudinal beams 63 extending along the length of the trailer body and a plurality of beams 62 vertically connected between the longitudinal members 63. At the bottom of the front body 6, there is also a traction pin and pin plate assembly 5 for connection with the power traction mechanism in front of the trailer, the structure of which is similar to the general structure of the portion, and will not be described in detail herein.
本实施例的挂车车身在正常运行时， 挂车为设计制造标准落差位置， 该牵引销及销板 总成 5与挂车前方的动力牵引机构相连接，该上脖颈 21整体为水平方向，该铰轴支架 231 呈竖直方向， 该三角中位垫铁 24插设在该斜向支承平面 221 1与该主纵梁 1 1的上表面之 间的三角区域内， 从而在该后部车身 1与该铰接装置 2之间形成一稳定的结构。 In the normal operation of the trailer body of the embodiment, the trailer is designed and manufactured to a standard drop position, and the traction pin and pin plate assembly 5 is connected with a power traction mechanism in front of the trailer, and the upper neck 21 is horizontally oriented as a whole. The bracket 231 is in a vertical direction, and the triangular intermediate horn 24 is inserted in a triangular region between the oblique support plane 221 1 and the upper surface of the main longitudinal beam 11 , so that the rear body 1 and the rear A stable structure is formed between the hinge devices 2.
当通过具有障碍的特殊地段时： 先停车， 启动该顶伸机构 3使得其顶端顶动该颈脖座 22, 从而使得该铰接装置 2相对该后部车身 1以该铰轴 232为中心逆时针旋转后固止， 因 此该铰接装置 2与该后部车身 1的连接部分向上拱起 (蓄能器供油，液压悬挂伸出) (另油缸 与悬挂缸油路联接并切换控制车身可柔性工作)， 此时可顺利地越过障碍； 越过障碍之后 再停车， 控制该顶伸机构 3回位， 该后部车身 1以及该铰接装置 2恢复正常运行时的状态 即可正常行驶。 When passing through a special section with obstacles: first stop, the top extension mechanism 3 is activated such that its top end pushes the neck collar 22, so that the hinge device 2 is counterclockwise with respect to the rear body 1 with the hinge shaft 232 as a center. After the rotation is fixed, the connecting portion of the hinge device 2 and the rear body 1 is upwardly arched (the accumulator is supplied with oil, and the hydraulic suspension is extended) (the other cylinder is coupled with the suspension cylinder oil passage and is switched to control the body to work flexibly) At this time, the obstacle can be smoothly passed; after the obstacle is over, the parking mechanism 3 is controlled to return to the position, and the rear body 1 and the hinge device 2 can be normally driven when the state of normal operation is resumed.
当通过具有高度限制的特殊地域时， 也需先停车， 启动该顶伸机构 3使得其顶端顶动 该颈脖座 22， 从而使得该铰接装置 2相对该后部车身 1以该铰轴 232为中心逆时针旋转， 该脖颈座 22底端的该斜向支承平面 221 1脱离该三角中位垫铁 24的支承， 此时将该三角 中位垫铁 24转出或取出， 然后再控制该顶升机构 3回位 (蓄能器回油， 液压悬挂缩回）（另 油缸与悬挂缸油路联接并切换控制车身可柔性工作)， 该铰接装置 2相对该后部车身 1顺 时针方向回转至该斜向支承平面 221 1变位向该后部车身 1 的上表面， 此时该铰接装置 2 与该后部车身 1的连接部分向下塌陷， 从而造成该后部车身 1的前端向下倾斜， 使得该后 部车身 1上货物的总高度降低， 因此顺利通过该高度限制的特殊地域； 越过该区域之后再 停车， 启动该顶伸机构 3顶动该脖颈座 22, 再将该三角中位垫铁 24插回或转回原位， 该 后部车身 1以及该铰接装置 2恢复正常运行时的状态即可正常行驶。 When passing through a special area with a height restriction, it is also necessary to stop first, and the top extension mechanism 3 is activated such that the top end thereof moves the neck holder 22, so that the hinge device 2 is opposite to the rear body 1 by the hinge shaft 232. The center rotates counterclockwise, the oblique bearing plane 221 1 at the bottom end of the neck seat 22 is disengaged from the support of the triangular middle horn 24, and the triangular intermediate horn 24 is turned out or taken out, and then the jacking is controlled. The mechanism 3 returns (the accumulator returns to the oil, the hydraulic suspension retracts) (the other cylinder is coupled with the suspension cylinder oil passage and switches to control the body to work flexibly), and the hinge device 2 is rotated clockwise relative to the rear body 1 to The oblique bearing plane 221 1 is displaced toward the upper surface of the rear body 1 at which time the connecting portion of the hinge device 2 and the rear body 1 collapses downward, thereby causing the front end of the rear body 1 to tilt downward. The total height of the cargo on the rear body 1 is lowered, so that the special area limited by the height is smoothly passed; after the area is over and then stopped, the extension mechanism 3 is activated to push the neck seat 22, and then the triangle is When the center horn 24 is inserted back or turned back to the original position, the rear body 1 and the hinge device 2 can be normally driven when they are restored to normal operation.
该挂车通过在与上脖颈 21 固定连接成一体的脖颈座 22 的底端设置斜向支承平面 2211、 铰轴 232以及三角中位垫铁 24， 并通过顶伸机构 3的作用， 从而调整该铰接装置 2 与该后部车身 1的髙度以及相对位置以满足特殊区域的通过需求，而且该后部车身 1与该 铰接装置 2之间的连接为可拆卸的结构， 因此使用时可十分方便地从该后部车身 1的前端 装卸货物。 The trailer is provided with an oblique support plane 2211, a hinge shaft 232 and a triangular intermediate horn 24 at a bottom end of the neck seat 22 fixedly coupled to the upper neck 21, and is adjusted by the action of the extension mechanism 3, thereby adjusting the hinge The twisting and relative position of the device 2 and the rear body 1 satisfy the passage requirements of the special area, and the connection between the rear body 1 and the hinge device 2 is a detachable structure, so that it can be conveniently used. From the front end of the rear body 1 Loading and unloading goods.
