- the present invention also makes a special design for the leg device 300.
- a locking assembly 400 is provided on the support crossbeam 310, and the locking assembly 400 includes a rotating shaft 410 and a locking member 420.
- the rotating shaft 410 and the locking member 420 are both cylindrical structures, and the rotating shaft 410 and the locking member 420 are both rotatably provided on the support crossbeam 310, and the cylindrical surface of the rotating shaft 410 and the cylindrical surface of the locking member 420 are in contact with each other.
- a clamping notch 411 is provided on the cylindrical surface of the rotating shaft 410, and an unlocking notch 421 is provided on the cylindrical surface of the locking member 420. Through the cooperation of the clamping notch 411 and the unlocking notch 421, different connection states between the rotating shaft 410 and the locking member 420 can be achieved, thereby determining whether the support crossbeam 310 is drivenly connected to the chain transmission component 250.
- a bearing (not shown) is provided between the rotating shaft 410 and the supporting beam 310.
- the bearing can reduce the friction between the rotating shaft 410 and the supporting beam 310, thereby making the rotating shaft 410 rotate more smoothly.

- the staff When it is necessary to cut off the connection between the leg device 300 and the chain transmission component 250, the staff only needs to rotate the locking member 420 so that the unlocking notch 421 of the locking member 420 faces the rotating shaft 410.
- the rotating shaft 410 can achieve free rotation with the help of this avoidance space (as shown in Figure 10). In this way, if the rotating shaft 410 is driven to rotate by the sprocket 252 at this time, the rotating shaft 410 will rotate freely in the supporting beam 310, and will not be able to drive the supporting beam 310 to rotate, that is, the transmission between the sprocket 252 and the supporting beam 310 is cut off. In this way, the leg device 300 will not be unfolded under the drive of the chain transmission component 250, while other leg devices 300 that are not in operation can still be unfolded smoothly;
- the staff When the transmission connection needs to be restored, the staff needs to first rotate and adjust the clamping notch 411 of the rotating shaft 410 to face the locking member 420 (which can be automatically adjusted through the program set by the controller 210); then, the staff rotates the locking member 420 so that the unlocking notch 421 of the locking member 420 no longer faces the rotating shaft 410 (as shown in FIG. 11 ), and the cylindrical surface of the locking member 420 sinks into the clamping notch 411. In this way, the rotating shaft 410 and the locking member 420 are restored to the initial state, and the supporting crossbeam 310 is drivingly connected with the chain transmission component 250 again.
- each leg device 300 is provided with a locking assembly 400, through which the staff can control whether the leg device 300 is drivingly connected to the chain transmission component 250.
- the locking assembly 400 has a simple and reliable structure, and its operation is convenient and quick. The staff only needs to rotate the locking member 420 to change the matching relationship between the locking member 420 and the rotating shaft 410 to change the transmission connection of the leg device 300.
- the locking assembly 400 of the present invention further includes a limiting slider 430 (as shown in FIG8 ).
- the limit slider 430 is slidably disposed in the support beam 310 through a return spring 431 , the limit slider 430 is abutted against the cylindrical surface of the locking member 420 , a toggle rod 432 is provided on the limit slider 430 , and a positioning groove 422 (as shown in FIG11 ) cooperating with the limit slider 430 is provided on the locking member 420 .
- the unlocking notch 421 of the locking member 420 faces the limiting slider 430, and the limiting slider 430 is held in the unlocking notch 421 under the action of the return spring 431, so that the unlocking notch 421 and the limiting slider 430 are mutually engaged, and the locking member 420 can be stably maintained in the current state;
- the unlocking notch 421 of the locking member 420 faces the rotating shaft 410, and the positioning groove 422 faces the limiting slider 430.
- the limiting slider 430 and the positioning groove 422 are mutually engaged, so that the locking member 420 is kept at the current position without misalignment.
- the limiting slider 430 will always be against the cylindrical surface of the locking member 420, so that the locking member 420 needs to overcome a certain resistance when rotating, so that the locking member 420 will not be easily deflected and misplaced.
- the toggle rod 432 on the limiting slider 430 can facilitate the staff to toggle the limiting slider 430 so that the limiting slider 430 is separated from the unlocking notch 421 or the positioning groove 422 of the locking member 420, so that the locking member 420 can be rotated by the staff.

Description
本发明涉及移动平台技术领域,特别是涉及一种全自动展开式的抢险救援移动平台。
抢险救援移动平台是一种用于搭载救援设备的机座,其能够为救援设备提供支撑。比如,抢险救援移动平台可用于搭载照明灯塔,抢险救灾时,搭载有将照明灯塔的移动平台能够快速、且稳定地架设在救灾现场,从而为现场提供照明。再比如,抢险救援移动平台还可以搭载通讯电塔,从而方便快捷地为现场提供通讯信号。
常见的抢险救援移动平台上设置有支腿,支腿能够对平台的稳定性起到关键作用,其在不需要增加平台宽度和降低机动性能的前提下,为该移动平台提供较大的支撑跨度,从而提高移动平台的稳定性和安全性。
目前,市面上的抢险救援移动平台在展开支腿时,多数采用人工的方式,即需要工作人员手动展开平台周围的多个支腿,来实现支腿的伸出动作;而少数移动平台虽说也是机械传动控制展开支腿,但它的局限性是支腿只能一个个地展开。可见,无论是人工还是机械展开方式,这些操作都比较费事费力,且工作效率较低。
在实际使用中发现,抢险救援移动平台的四个支腿装置同时活动虽然能够提高工作效率,但是需要有充足的场地空间;当其中某一个支腿装置受到阻挡而无法展开时,抢险救援移动平台的支腿装置便会制约而无法展开。为了能够不影响其他支腿装置的正常展开,抢险救援移动平台的支腿装置能够根据需要选择是否展开,从而提高抢险救援移动平台对不同场地的适应能力。
本发明的目的是通过以下技术方案来实现的:

本发明提供一种全自动展开式的抢险救援移动平台10,如图1及图2所示,其包括:基座本体100、驱动装置200以及四个支腿装置300,四个支腿装置300可转动地设于基座本体100的四周上,驱动装置200安装于基座本体100上,且驱动装置200与支腿装置300驱动连接;
如图3及图4所示,驱动装置200包括:控制器210、主传动部件220、左传动部件230以及右传动部件240,主传动部件220受到控制器210控制,主传动部件220驱动连接左传动部件230及右传动部件240,左传动部件230驱动其中位于基座本体100同一侧的两个支腿装置300,右传动部件240驱动位于基座本体100另一侧的两个支腿装置300。
使用时,主传动部件220带动左传动部件230及右传动部件240,而左传动部件230与右传动部件240各自带动两个支腿装置300。当抢险救援移动平台10搬运到指定位置后,工作人员按压遥控,从而触发控制器210,控制器210发送电信号给主传动部件220,再经过左传动部件230以及右传动部件240,带动四个支腿装置300同时展开。这样便可以实现四个支腿装置300一键自动展开,从而节省精力和时间,提高工作效率。
下面,对抢险救援移动平台10的主要结构进行说明:
如图5所示,主传动部件220包括:减速电机221、主动轮222、左从动轮223以及右从动轮224,减速电机221驱动主动轮222,左从动轮223与右从动轮224分别位于主动轮222的两侧,且左从动轮223与右从动轮224均啮合于主动轮222。
如图6所示,右传动部件240包括:右驱动轮241、逆反轮242、第一传动轮243以及第二传动轮244,右驱动轮241啮合于第一传动轮243,且右驱动轮241通过逆反轮驱动242第二传动轮244,右从动轮224驱动连接右驱动轮241。
也就是说,右传动部件240具有两条传输路线,其中一条路线是,由右驱动轮241啮合驱动第一传动轮243,第一传动轮243的转动方向与右驱动轮241的转动方向相反;另一条路线是,先由右驱动轮241传递给逆反轮242,然后再由逆反轮242传递到第二传动轮244,这样,多经过了逆反轮242,第二传动轮244的转动方向便与右驱动轮241的转动方向相同,即与第一传动轮243的转动方向相反。使用时,参考图4、图5及图6所示,第一传动轮243驱动连接一个支腿装置300,第二传动轮244驱动连接另一个支腿装置300,两者转动方向相反,这样设置后,两者正好可以驱动两个支腿装置300一起展开或者回收。
相应的,左传动部件230的结构与右传动部件240的结构相同。
在本实施例中,如图4所示,驱动装置200包括链传动部件250,左传动部件230通过链传动部件250与其中两个支腿装置300驱动连接,右传动部件240通过链传动部件250与另外两个支腿装置300驱动连接。
如图4所示,链传动部件250包括:主链轮251、从链轮252以及链条253。主链轮251设于所需的传动轮上,从链轮252设于支腿装置300上,链条253首尾相接地绕设于主链轮251与从链轮252上。如此,左传动部件230或者右传动部件240便可以通过链传动部件250带动支腿装置300转动。
在本实施例中,如图7所示,支腿装置300包括支撑横梁310以及液压柱320,支撑横梁310铰接于基座本体100上,液压柱320设于支撑横梁310的末端。使用时,从链轮252与支撑横梁310的一端同轴连接,主链轮251随传动轮旋转时,从链轮252在链条253带动下一起旋转,进而驱动支撑横梁310以铰接处为轴做旋转运动。
接下来,结合上述结构,对本发明的抢险救援移动平台10的主要工作原理进行说明(请一并参考图4至图6):
使用时,工作人员先将抢险救援移动平台10运输到救灾现场,然后通过遥控触发控制器210,控制器210发送电信号给主传动部件220,主传动部件220同时驱动左传动部件230和右传动部件240;
其中,减速电机221驱动主动轮222,主动轮222带动右从动轮224旋转,右从动轮224通过链传动部件250驱动右驱动轮241旋转。在右传动部件240中,右驱动轮241啮合驱动第一传动轮243,第一传动轮243通过链传动部件250带动一个支腿装置300(第一传动轮243与一个主链轮251同轴连接);并且,右驱动轮241通过逆反轮242带动第二传动轮244,第二传动轮244通过链传动部件250驱动另一个支腿装置300(第二传动轮244也与一个主链轮251同轴连接)。这样,右传动部件240便可以同时控制两个支腿装置300展开或回收。展开后,设置在支撑横梁310末端的液压柱320逐渐延伸至接触地面,实现对抢险救援移动平台10的支撑;
与此同时,主动轮222带动左从动轮223旋转,左从动轮223通过链传动部件250驱动左传动部件230。左传动部件230的传动路径与上述的右传动部件240相似。最终由左传动部件230通过两个链传动部件250分别带动余下的两个支腿装置300。这样,减速电机221只需要驱动主动轮222,便可以同时带动四个支腿装置300一起展开或回收,从而节省了精力和时间,提高了工作效率。
至此,抢险救援移动平台10的主要工作原理说明完毕。
进一步地,在实际使用中发现,抢险救援移动平台10的四个支腿装置300同时活动虽然能够提高工作效率,但是需要有充足的场地空间;当其中某一个支腿装置300受到阻挡而无法展开时,上述抢险救援移动平台10的支腿装置300便会制约而无法展开。为了能够不影响其他支腿装置300的正常展开,使得抢险救援移动平台10的支腿装置300能够根据需要选择是否展开,从而提高抢险救援移动平台10对不同场地的适应能力,本发明还对支腿装置300做了特别设计。
具体地,如图8所示,支撑横梁310上设有锁合组件400,锁合组件400包括绕转轴410以及锁止件420。其中,绕转轴410与锁止件420均为柱体结构,且绕转轴410与锁止件420均转动设于支撑横梁310上,绕转轴410的柱面与锁止件420的柱面相互贴合。在绕转轴410的柱面上开设有卡持缺口411,锁止件420的柱面上开设有解锁缺口421。通过卡持缺口411、解锁缺口421的配合,能够实现绕转轴410与锁止件420之间不同的连接状态,从而决定支撑横梁310是否与链传动部件250实现驱动连接。
优先的,绕转轴410与支撑横梁310之间设有轴承(图未示)。轴承可以减小绕转轴410与支撑横梁310之间的摩擦力,从而使绕转轴410的转动更加顺畅。
下面,对锁合组件400的工作原理进行阐述说明:
首先,要说明的是,绕转轴410与链传动部件250的从链轮252同轴连接,从链轮252会带动绕转轴410一起旋转;
在初始状态下,如图9所示,绕转轴410与锁止件420贴合,且锁止件420的柱面陷入绕转轴410的卡持缺口411中,则锁止件420的柱面与卡持缺口411相互卡持。此时,若从链轮252带动绕转轴410旋转,由于相互卡持,绕转轴410转动的力矩会传递到锁止件420上,并由锁止件420的柱面再传递到支撑横梁310上。也就是说,绕转轴410的力矩会作用在支撑横梁310上,进而带动支撑横梁310以绕转轴410为中心做旋转运动;
当需要切断该支腿装置300与链传动部件250的连接时,工作人员只需要转动锁止件420,使锁止件420的解锁缺口421朝向绕转轴410。此时,由于解锁缺口421提供了一定的避让空间,则绕转轴410便可以凭借此避让空间实现自由旋转(如图10所示)。这样,若此时从链轮252带动绕转轴410旋转,则绕转轴410将会在支撑横梁310内自由旋转,而无法带动支撑横梁310转动,即切断了从链轮252与支撑横梁310之间的传动。如此,该支腿装置300便不会在链传动部件250的驱动下展开,而其他无进行操作的支腿装置300仍可顺利展开;
当需要恢复传动连接时,工作人员需要先将绕转轴410的卡持缺口411旋转调节至朝向锁止件420(可通过控制器210设定的程序进行自动调节);随后,工作人员转动锁止件420,使得锁止件420的解锁缺口421不再朝向绕转轴410(如图11所示),且锁止件420的柱面陷入到卡持缺口411中。这样,绕转轴410与锁止件420便复位到初始状态,支撑横梁310再次与链传动部件250驱动连接。
要强调说明的是,每一个支腿装置300上均设置有锁合组件400,工作人员通过该锁合组件400便可以控制支腿装置300是否与链传动部件250驱动连接。并且,该锁合组件400的结构简单可靠,其操作方便快捷,工作人员只需要旋转锁止件420,从而改变锁止件420与绕转轴410的配合关系,便可以改变支腿装置300的传动连接。
更进一步地,由上述可知,锁止件420的位置是决定锁合组件400状态的关键,为此,需要防止锁止件420因机身抖动等因素导致的错位现象。因此,本发明的锁合组件400还包括限位滑块430(如图8所示)。
具体地,如图8所示,限位滑块430通过复位弹簧431滑动设于支撑横梁310内,限位滑块430抵持于锁止件420的柱面,限位滑块430上设有拨动杆432,锁止件420上开设有与限位滑块430配合的定位槽422(如图11所示)。
使用时,当处于初始状态时,锁止件420的解锁缺口421朝向限位滑块430,限位滑块430在复位弹簧431的作用下抵持于解锁缺口421内,这样,解锁缺口421与限位滑块430相互卡持,锁止件420便可以稳定保持在当前状态;
当断开传动连接时,锁止件420的解锁缺口421朝向绕转轴410,定位槽422朝向限位滑块430,此时,限位滑块430与定位槽422相互卡持,使得锁止件420保持在当前位置,且不需要发生错位;
并且,在锁止件420旋转过程中,限位滑块430会始终抵持在锁止件420的柱面上,使锁止件420在转动时需要克服一定的阻力,从而使得锁止件420不会轻易偏转错位。限位滑块430上的拨动杆432能够方便工作人员拨动限位滑块430,使限位滑块430脱离于锁止件420的解锁缺口421或者定位槽422,从而使得锁止件420能够被工作人员转动。
为了使工作人员能够方便转动锁止件420,在本实施例中,锁止件420上设有扭转握持块423(如图12所示)。工作人员通过拧动扭转握持块423,便可以很方便地驱动锁止件420旋转。
在另一个实施例中,为了防止无关人员随意拧动锁止件420,进而在锁止件420上开设有扭转凹槽424(如图13所示),该扭转凹槽424为多棱柱体结构。并且,锁合组件400还包括扭转钥匙(图未示),扭转钥匙可拆卸地插接于扭转凹槽424内。也就是说,转动锁止件420时,工作人员需要使用指定的扭转钥匙,将扭转钥匙插接进扭转凹槽424后,才能转动锁止件420。调节完成后,工作人员将扭转钥匙取走,无关人员便不容易拧动锁止件420。
在其中一个实施例中,如图7所示,链传动部件250还包括支撑轨254,支撑轨254上开设有引导凹槽(图未示),链条253穿设并滑动于引导凹槽内。支撑轨254为链条253提供了支持力,以防止链条253中部下垂;并且,引导凹槽可以为链条253提供限位引导的作用,从而防止链条253抖动或错位。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
本发明的全自动展开式的抢险救援移动平台能够同时控制多个支腿装置的展开或回收,从而实现便捷操作和提高工作效率。抢险救援移动平台的四个支腿装置同时活动虽然能够提高工作效率,但是需要有充足的场地空间;当其中某一个支腿装置受到阻挡而无法展开时,抢险救援移动平台的支腿装置便会制约而无法展开。为了能够不影响其他支腿装置的正常展开,本发明的抢险救援移动平台的支腿装置能够根据需要选择是否展开,从而提高抢险救援移动平台对不同场地的适应能力。
