本发明涉及空港地面设备技术领域,具体是指一种传送平台自动调平装置及装载机。
背景技术
集装货物装载机广泛用于各大机场,现有的装载机一般包括底盘、整车PLC控制器、锂电池动力装置和行驶电机,整车PLC控制器用于控制电动式机场集装货物装载机工作,底盘上连接有前桥和传送平台,传送平台包括主平台和桥平台,主平台设有传送电机、链条、传送滚轮和电机控制器,桥平台设有传送电机、链条、传送滚轮和电机控制器,主平台与桥平台对接完成货物输送,如中国专利CN214059744U公开了一种电动式飞机集装升降平台车,其特征在于:其包括车架、操作台、主平台、桥平台和动力部分,所述动力部分包括电池舱、主电机、再生电机、行驶电机、第一液压泵、第二辅助液压泵、液压马达、逆变器,所述主平台和桥平台上分别设置有履带和万向轮,所述桥平台上固设有所述操作台,所述车架通过第一举升机构和所述主平台连接,所述车架通过第二举升机构和所述桥平台连接,所述第一举升机构驱动所述主平台升降动作,所述第二举升机构驱动所述桥平台升降动作,使用时,主平台的第一举升机构托着主平台升到与桥平台一样高的位置,与之对接,实现货物传递,上述专利与现有技术的不足是:一是主平台和桥平台通过举升机构举升高度一致方可对接,但是主平台和桥平台的高度一致需要多次调节,费时费力,间接导致货物传送速度低;二是主平台和桥平台高度不一致时,货物传输就容易卡滞,影响输送效率,还可能将货物颠出去;三是主平台在举升过程中,如果没有限位,上升速度太快,主平台可能会将桥平台掀翻,撞到飞机上;四是上述专利中操作台设置在桥平台一侧,导致桥平台重心偏移,容易向操作台一侧倾斜,甚至有侧翻的风险;五是上述专利中没有设置升降梯,当桥平 台升起后,操作人员无法从操作台下来或者操作人员无法进入桥平台,只能等桥平台完全落下,操作人员才能进出操作台或桥平台,但是货物对接的时候可能会出现问题,需要操作人员及时查看,这就显得很不方便;六,桥平台上通常会安装固定护栏,防止货物从远离操作台的一侧滑出,但是现有的固定护栏,缺少检测机构,操作人员偶有忘记,护栏未旋转到桥平台后部,装载机就开始行走,在装载机在与飞机或者别的设备对接时,护栏容易撞到飞机或者别的设备,操作不安全;七是桥平台与主平台对接后进行货物传输时,桥平台可能会左右摆动,导致货物传输不稳定,可能需要多次调整货物。
发明内容

如附图1、附图4、附图5和附图6,本发明主平台和桥平台之间设有自动调平机构,附图5为主平台上升即将与桥平台齐平时的局部放大示意图,为减少主平台和桥平台对接间隙,可在桥平台朝向主平台的一端中部设置一个凹槽,用于安装自动调平机构,附图1和附图4所示,挡板安装在桥平台的凹槽内,桥平台上可设置一个挡板,也可以设置两个挡板,当设置一个挡板时,挡板中间偏上的位置与桥平台铰接,挡板一端朝下朝向挡板并固定安装低位传感器,挡板另一端朝上,朝上的挡板与桥平台之间依次间隔设置挡板放下传感器、跟随传感器、相平传感器、高位传感器、超高停机保护传感器,挡板放下传感器、跟随传感器、相平传感器、高位传感器、超高停机保护传感器在桥平台上的位置高度依次降低;当设置两个挡板时,如附图6所示,桥平台的凹槽内,左面设置左挡板,右面设置右挡板,左挡板中上部和右挡板中上部分别与桥平台铰接,左挡板下端固定安装低位传感器,左挡板右端与桥平台之间设置挡板放下传感器、相平传感器和超高停机保护传感器,挡板放下传感器、相平传感器和超高停机保护传感器分别固定在桥平台上并与左挡板间隔设置,挡板放下传感器、相平传感器和超高停机保护传感器在桥平台上的位置高度依次降低,右挡板左端朝下呈自由端,右挡板右端和桥平台之间设置跟随传感器、高位传感器和超高停机保护传感器,跟随传感器、高位传感器和超高停机保护传感器固定在桥平台上,并与右挡板间隔设置,跟随传感器、高位传感器和超高停机保护传感器在桥平台上的位置高度依次降低,本实施例中超高停机保护传感器设置两个,也可以设置一个,根据需求设置即可,托板位于两个挡板的下方,用于托起并带动两个挡板转动,低位传感器可以设置成主平台上端面高度低于桥平台上端面高度为100mm时感应,跟随传感器可以设置成主平台上端面高度低于桥平台上端面高度为30mm时感应,挡板放下传感器可以设置成主平台上端面高度低于桥平台上端面高度在100-30之间任意数值时感应,用于感应挡板被托起,相平传感器设置成主平台上端面高度和桥平台上端面高度一致时感应,高位传感器可以设置成主平台上端面高度高于桥平台上端面高度为20mm时感应,超高停机保护传感器可根据要求设置主平台上端面高度高于桥平台上端面高度的数值,比如30mm-50mm之间任意数值时感应,本发明所述各传感器的实施例数值不局限于本实施例中的具体数值,可根据具体需求来设定,使用时,以桥平台上安装左挡板和右挡板两个挡板为例,当主平台从低位开始快速上升至低于桥平台100mm时,托板上端面抵在左挡板右端的低位传感器上,低位传感器接收到信号并传递给PLC控制器,PLC控制器控制主平台的举升机 构,使得主平台的上升速度由快速降为慢速,主平台慢速继续上升,挡板放下传感器感应到左挡板,表明主平台在持续上升,托板托着左挡板右端和右挡板左端分别向上转动,使得左挡板左端和右挡板右端向下转动,直到主平台上升至低于桥平台38mm,跟随传感器感应到右挡板右端,将信号传递给PLC控制器,PLC控制器控制主平台的举升机构和桥平台的举升机构,主平台处于跟踪升降状态,能跟随桥平台同时升降,直至相平,主平台和桥平台上端面高度一致时,相平传感器接收到信号,传递给PLC控制器,PLC控制器控制主平台的举升机构,使得主平台停止上升,可以进行货物输送工作;如果低位传感器、挡板放下传感器以及相平传感器出故障,导致主平台继续上升,当主平台上升到高于桥平台20mm时,高位传感器感应到右挡板,将信号传递给PLC控制器,PLC控制器控制主平台的举升机构,使得主平台下降;如果高位传感器也出现故障,导致主平台继续上升,左挡板右端和右挡板左端随托板不停上升,使得超高停机保护传感器感应到左挡板左端和右挡板右端,将信号传递给PLC控制器,PLC控制器控制主平台和桥平台同时停止升降,待工作人员维修后再次使用,本发明结构简单,通过自动调平机构使得主平台可自动对接桥平台,调节速度快、对接平稳、货物传送流畅,不卡滞,间接提高了货物传送速度。
如附图3,附图7-附图9,本发明中还设置了桥平台防侧倾机构,为方便描述,以图3的方位来说明,桥平台右侧设置操作台,这使得桥平台的重心会右移,容易向右倾斜,甚至有发生侧翻的风险,本发明在桥平台左侧设置桥平台防侧倾机构,桥平台下端与底盘之间设有举升机构,举升机构为现有技术,举升机构的剪刀架由驱动缸驱动,剪刀架包括剪刀臂,如附图3,一个剪刀臂上端与桥平台下端前部铰接,另一个剪刀臂上端经滚轮与桥平台下端后部滑动连接,滚轮活动安装在滚轮轴上,滚轮轴两端与剪刀臂固定连接,桥平台左侧下端的剪刀臂的滚轮轴上活动安装有挂钩,桥平台左侧下端设置导向支撑板,导向支撑板右侧与桥平台固定连接,滑杆压在导向支撑板上,连接块下端与滚轮轴铰接,使得连接块可相对滚轮轴前后摆动,在桥平台升降过程中,滑杆可始终紧靠在导向支撑板上,沿着导向支撑板滑动,确保桥平台在升降过程中,时时受到挂钩的约束,不会倾斜。
如附图2、附图10-附图13,本发明在操作台一侧设置了升降梯,升降梯由上梯子、浮动梯和下梯子组成,当桥平台通过举升机构驱动上升时,桥平台带动上梯子上升,上梯子上行,直到上梯子的挂板与浮动梯的卡钩板卡接,上梯子继续上升,通过挂板、卡钩板带动浮动梯上升,桥平台上升到位后,上梯子、浮动梯停止上升,浮动梯上端通过卡钩板与挂板卡接,下端经滑块与滑道连接,浮动梯结构稳定,不会晃动,此时,操作人员可手扶着下把手从下梯子依次通过浮动梯、上梯子进入桥平台,当桥平台下降时,桥平台下降带动上梯子 下降,上梯子下行,浮动梯不动,上梯子的挂板与卡钩板分开,上梯子继续下行,上梯子下端的压块触碰浮动梯的挡块,上梯子继续下行,压块压着挡块带动浮动梯下行,直到桥平台停止下降,上梯子和浮动梯随之停止。
如附图1-附图3,附图14-18,本发明在桥平台左侧,也就是远离操作台的一侧设置旋转护栏,如附图14和附图17,旋转护栏和桥平台之间设有护栏旋转检测机构,感应器与整车PLC控制器连接,如附图1-附图3所示,旋转护栏在桥平台侧边,此时,感应板位于感应器侧边,感应器感应不到感应板,整车PLC控制器接收不到感应器的信号,此时装载机不能行走,如果此时装载机行走与飞机对接,活动护栏可能会撞到飞机,故装载机不动,操作人员手动向上拉插销,使得插销从第一杆孔拔出,手动转动旋转护栏,将旋转护栏向后旋转,旋转护栏转动到桥平台后端,松开插销,插销下端插入桥平台后端的第二杆孔内,旋转护栏固定在桥平台后端,在这个过程中,旋转护栏旋转带动感应板转动,当旋转护栏旋转至桥平台后端时,感应板旋转到感应器正上方,感应器感应到感应板将信号传递给整车PLC控制器,整车PLC控制器启动行走机构,装载机可行走,本发明还设置了活动护栏支撑导向滑动机构和活动护栏下压导向机构,如附图15和附图16,护栏杆下端面与支撑滚轮上端面相抵靠,护栏杆上端面与导向滚轮下端面相抵靠,支撑滚轮、导向滚轮均可滚动,支撑滚轮可以支撑导向护栏杆,导向滚轮可以导向护栏杆伸缩又可以促使护栏杆贴紧护栏滑道,不会翘起,支撑滚轮与导向滚轮一起夹持护栏杆,确保护栏杆伸出缩回流畅。
如附图1-附图4以及附图19,本发明在主平台和桥平台之间还设置了主平台桥平台连接机构,连接滚轮经轴套与连接轴连接,连接滚轮可转动,当主平台上升时,主平台带动连接滚轮上升,连接滚轮由下向上进入连接开口槽,连接开口槽下端呈喇叭状张开,方便连接滚轮进入连接开口槽,当主平台上升到与桥平台齐平时,连接滚轮置于连接开口槽内,连接滚轮外表面至少与连接开口槽一侧侧壁相挤压,这使得在货物运输作业时,当桥平台不稳定要左右摆动时,桥平台的连接开口槽与连接滚轮挤压连接可带动主平台摆动,但是主平台重量大,不会摆动或晃动,主平台会反过来通过连接滚轮挤压连接开口槽使得桥平台无法左右摆动,实现桥平台的稳定。
本发明中装载机的行走可采用液压驱动,也可以采用电动驱动;主平台的举升机构的驱动缸可以是电动缸也可以是液压缸,桥平台的举升机构的驱动缸可以是电动缸也可以是液压缸;主平台与底盘之间的举升机构的驱动缸可以是液压缸,也可以是电动缸,桥平台与底盘之间的举升机构的驱动缸可以是液压缸,也可以是电动缸,主平台和桥平台上货物传输的驱动可以是液压驱动也可以是电动驱动,当采用电动驱动时,传送电机驱动传送滚轮旋转 用于传送货物,传送滚轮的结构采用现有技术,此不赘述,通过不同转向的滚轮组合,实现货物的前进、后退、左移动、右移动和360°旋转,一个电机控制器同时控制若干个传送电机,整车PLC控制器通过检测开关信号、方向信号及速度需求信号,将转速指令发送至电机控制器中,整车PLC控制器根据需求调整转速指令,控制滚轮传送速度,传送电机可为永磁减速电机,永磁减速电机为减速器、温度传感器和永磁电动机一体结构,永磁电动机为异步启动永磁同步电动机,其为表面式转子结构,永磁体用高强度不锈钢圈固定于启动笼转子的外部,电机的转子轴与减速器为一体式结构,永磁电机的定子上装有温度传感器,永磁电机的定子、转子和减速器通过两端的端盖封装于电机的机壳内,电机的后盖上设置有冷却风扇,风扇通过冷却机壳表面的散热筋从而带走电机工作时的热量,电机控制器可判断传送电机的故障状态,当永磁电动机的工作电流大于电流预设值时,电机控制器可以切断该传送电机的工作电源,电机控制器还用于判断传送电机的温度状态,当永磁电动机的温度过高时,电机控制器根据具体温度值采取降额或停机处理,以上装载机的行走、主平台的升降、桥平台的升降、主平台和桥平台上货物传输的驱动,既可以采用电动驱动也可以采用液压驱动,还可以两者结合使用,根据需要选择即可。
本发明由于采用上述结构,具有主平台与桥平台对接高度一致、对接平稳、桥平台不会侧倾、护栏旋转有检测、升降梯踩踏平稳等优点。
