Description
技术领域technical field
本发明涉及车辆防倾覆技术领域，具体来说涉及一种半挂车集装箱防倾覆结构。The invention relates to the technical field of vehicle anti-overturning, in particular to an anti-overturning structure for a semi-trailer container.
背景技术Background technique
针对港口作业特点，场地作业车辆，如半挂车、牵引车，发生倾覆的主要原因有以下四点：①频繁着箱冲击，②钢板弹簧本身金属疲劳，③频繁刹车或及转弯，④颠簸不平的路面上。集装箱倾覆临界角为46.4°，如果集装箱的倾斜角度超过46.4°，那么就会发生集装箱倾覆的安全事故。According to the characteristics of port operations, the main reasons for the overturning of site operation vehicles, such as semi-trailers and tractors, are as follows: ①Frequent box impact, ②Metal fatigue of the leaf spring itself, ③Frequent braking or turning, ④Bumpy on the road. The overturning critical angle of the container is 46.4°. If the tilting angle of the container exceeds 46.4°, a safety accident of container overturning will occur.
目前码头内集装箱倾覆事故多是挂车弹簧钢板瞬间断裂造成的，此类事故极易造成财产损失及人员伤害。影响弹簧钢板疲劳寿命的因素较多，较难通过经验数据确定钢板弹簧的更换周期，这给日常检查维护带来较大的难度。从车辆的技术状况，特别是从造成车辆或集装箱倾覆的悬架钢板来看，由于弹簧钢板金属疲劳，装卸箱对弹簧钢板造成冲击的频繁性以及路面状况复杂等原因，很难对悬架弹簧钢板的使用及技术状况进行统一的掌控，使用时间也无规律可循。At present, most container overturning accidents in the wharf are caused by the instantaneous breakage of the spring steel plate of the trailer. Such accidents can easily cause property loss and personal injury. There are many factors that affect the fatigue life of spring steel plates, and it is difficult to determine the replacement cycle of leaf springs through empirical data, which brings greater difficulty to daily inspection and maintenance. From the perspective of the technical condition of the vehicle, especially the suspension steel plate that causes the vehicle or container to overturn, it is difficult to correct the suspension spring due to the metal fatigue of the spring steel plate, the frequent impact of the loading and unloading box on the spring steel plate, and the complex road conditions. The use and technical status of steel plates are uniformly controlled, and there are no rules to follow in the use time.

具体实施方式Detailed ways
以下对本发明的具体实施方式进行详细说明，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。The specific embodiments of the present invention will be described in detail below, and it should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
如图1-图3所示，本实施例的半挂车集装箱防倾覆结构包括设置于半挂车托盘11和弹簧钢板12之间的防倾覆装置，防倾覆装置包括U型卡槽，卡槽上方设有连接板21、下方设有卡块22；卡槽卡入托盘横梁13上，连接板21连接于半挂车托盘11上，卡块22与弹簧钢板12之间具有间距。As shown in Figures 1-3, the anti-overturning structure of the semi-trailer container in this embodiment includes an anti-overturning device arranged between the semi-trailer pallet 11 and the spring steel plate 12. There is a connecting plate 21, and a block 22 is arranged below;
本实施例的半挂车集装箱防倾覆结构稳固可靠，卡块22位于弹簧钢板12上方，卡块22与弹簧钢板12之间具有间距，若弹簧钢板12出现断裂，那么卡块22会卡入弹簧钢板12断裂处，大大减小半挂车托盘11倾斜程度，从而可以有效防止半挂车上的集装箱（未在图中示出）倾覆，可以大大提高半挂车行驶安全性。The anti-overturning structure of the semi-trailer container in this embodiment is stable and reliable. The block 22 is located above the spring steel plate 12. There is a distance between the block 22 and the spring steel plate 12. If the spring steel plate 12 breaks, the block 22 will snap into the spring steel plate. 12, the inclination of the semi-trailer pallet 11 is greatly reduced, thereby effectively preventing the container (not shown in the figure) on the semi-trailer from overturning, and greatly improving the driving safety of the semi-trailer.
卡块22与弹簧钢板12之间的间距H为8-10cm。如果半挂车一侧的弹簧钢板12断裂，那么卡块22刚好可以卡入弹簧钢板12断裂处，卡块22所在的车体横梁13会倾斜，半挂车另一侧的车体横梁13未倾斜，那么可以计算得到倾斜的车体横梁13与未倾斜的车体横梁13之间的间距为50mm，且集装箱倾斜角度为3°，远远小于集装箱倾覆临界角46.4°，因此，集装箱不会出现倾覆现象，可以大大提高半挂车行驶安全性。The distance H between the block 22 and the spring steel plate 12 is 8-10 cm. If the spring steel plate 12 on one side of the semi-trailer is broken, the block 22 can just be inserted into the broken part of the spring steel plate 12, the vehicle body beam 13 where the clamp block 22 is located will be inclined, and the vehicle body beam 13 on the other side of the semi-trailer is not inclined. Then it can be calculated that the distance between the inclined vehicle body beam 13 and the non-inclined vehicle body beam 13 is 50mm, and the inclination angle of the container is 3°, which is far smaller than the container overturning critical angle of 46.4°. Therefore, the container will not overturn Phenomenon, can greatly improve the driving safety of semi-trailer.
卡槽包括第一卡板23，第一卡板23两端分别垂直设有第二卡板24和第三卡板25；第二卡板24的长度大于第三卡板25的长度，连接板21垂直设于第二卡板24上方。本实施例中，卡槽的高度，即第二卡板24和第三卡板25之间的间距N等于托盘横梁13的高度M，从而可以使得卡槽和托盘横梁13配合紧密稳固，从而可以使得防倾覆装置稳固连接在半挂车托盘上。The draw-in slot comprises a first clamp 23, and the two ends of the first clamp 23 are respectively vertically provided with a second clamp 24 and a third clamp 25; the length of the second clamp 24 is greater than the length of the third clamp 25, and the connecting plate 21 is vertically arranged above the second clamping plate 24 . In this embodiment, the height of the slot, that is, the distance N between the second clamping plate 24 and the third clamping plate 25 is equal to the height M of the pallet beam 13, so that the clamping slot and the pallet beam 13 can be tightly matched and stable, so that The anti-overturning device is firmly connected to the semi-trailer pallet.
卡块22为倒置的等腰梯形体状，第三卡板25连接于卡块22的上表面边缘处且与卡块22上表面在同一平面上。The clamping block 22 is in the shape of an inverted isosceles trapezoid, and the third clamping plate 25 is connected to the edge of the upper surface of the clamping block 22 and is on the same plane as the upper surface of the clamping block 22 .
卡块22的腰与下底的夹角θ为120°-150°，从而可以便于卡块22卡入弹簧钢板12断裂处。本实施例中，卡块22可以为6块板焊接而成的等腰梯形体状，可以减轻防倾覆装置的重量，降低防倾覆装置的制造成本。The angle θ between the waist of the clamping block 22 and the lower bottom is 120°-150°, so that the clamping block 22 can be easily inserted into the fractured part of the spring steel plate 12 . In this embodiment, the clamping block 22 may be in the shape of an isosceles trapezoid welded by six plates, which can reduce the weight of the anti-overturning device and reduce the manufacturing cost of the anti-overturning device.
防倾覆装置的材质为钢、通过焊接工艺一体成型，可以使得防倾覆装置结构稳固、强度高。The material of the anti-overturning device is steel, which is integrally formed by welding process, which can make the anti-overturning device have a stable structure and high strength.
以上实施例仅用以说明本发明的技术方案，而非对其进行限制；尽管参照下述实施例对本发明进行了详细的说明，对于本领域的普通技术人员来说，依然可以对下述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；而这些修改或替换，并不使相应技术方案的本质脱离本发明所要求保护的技术方案的精神和范围。The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the following embodiments, those of ordinary skill in the art can still implement the following The technical solutions described in the examples are modified, or some of the technical features are replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed in the present invention.
