The parking problem in the community has brought a lot of pressure. As an empty problem for motor vehicle parking, while improving the fire passage, greening quality and the overall environment of the community, the construction status of the parking facility is closely related to the urban traffic operation and the urban social and economic development. Over the past few years, "relieving parking difficulties" has always been the focus of the work of governments at all levels, congestion control offices and related departments. Because most of the old communities were built earlier, the community roads are narrow and the parking spaces are lacking, vehicles are generally parked beside the nearby roads. However, because the width of the road is less than 5 meters, the vehicles are parked in a concentrated manner during the evening rush hour, which can easily cause congestion and many problems. annoyed many residents. Therefore, it is imminent to manufacture a new, practical, and small-footprint parking device.
对此市面上出现了立体停车车库,以使得较小面积的空间能够竟可能多的停放车辆,交接卡爪是立体停车车库主要部件,然而,现有交接卡爪大都需要采用控制机构控制,故障率较高。上述问题,亟待解决。In this regard, three-dimensional parking garages have appeared on the market, so that as many vehicles as possible can be parked in a small area of space. The handover claws are the main components of the three-dimensional parking garage. However, most of the existing handover claws need to be controlled by a control mechanism. higher rate. The above problems need to be solved urgently.

具体实施方式Detailed ways
下面结合附图与具体实施方式对本发明作进一步详细描述:参见图1至图4,交接卡爪4,所述交接卡爪4包括卡口200 。所述交接卡爪4包括底板4a和盖设在所述底板4a上的盖板4b,在所述底板4a上转动设置有一双齿棘轮40,在所述双齿棘轮40上设置有销 40a,还包括一活动板41,所述活动板41上设置有与所述销40a配合的滑槽41a,所述销 40a和所述滑槽41a构成曲柄滑块机构,以使得所述双齿棘轮40在转动时,所述活动板41 的一端能够打开或者关闭所述卡口200。The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments: referring to FIGS. 1 to 4 , the
在所述双齿棘轮40上开设有线槽,柔性绳42绕过双齿棘轮的线槽180度,在所述柔性绳42上设置有阻挡部件,所述阻挡部件与双齿棘轮40中的一个棘齿顶靠,用于拨动所述双齿棘轮,本实施例中所述阻挡部件设置为绳结;在所述底板上设置有一弹性销100,所述弹性销100和所述双齿棘轮40中的另一个棘齿顶靠以用于充当制退器。所述双齿棘轮40 的一侧设置有滑轮44,所述柔性绳42通过所述滑轮44,所述柔性绳42的一端设置有拉簧 43。通过上述滑轮改变绳子的受力方向使其能使柔性绳绕棘轮转过180度,同时增加拉簧的拉伸行程。所述柔性绳42的另一端连接有一触发推板45,所述触发推板45在底板上的滑槽中滑动设置。A wire slot is provided on the double-
当推动触发推板时,触发推板在底板上的滑槽中滑动,其前端绕着柔性绳,柔性绳上的绳结推动棘轮旋转180度,同时位于交接卡爪底端的拉簧受力拉伸。棘轮上的销与活动板构成曲柄滑块机构,它们的运动状态改变从而改变交接卡爪的开闭状态。当松开触发推板,在拉簧的力的作用下,其会自动退回初始位置,同时柔性绳上的绳结也退回到原位。棘轮由于在充当制退器的弹性销的作用下,不会反转。When the trigger push plate is pushed, the trigger push plate slides in the chute on the bottom plate, the front end of the trigger push plate is wrapped around the flexible rope, the knot on the flexible rope pushes the ratchet wheel to rotate 180 degrees, and the tension spring at the bottom end of the handover claw is pulled by force stretch. The pins on the ratchet wheel and the movable plate constitute a crank-slider mechanism, and their movement states are changed to change the opening and closing states of the handover claws. When the trigger push plate is released, it will automatically return to the initial position under the force of the tension spring, and the knot on the flexible rope will also return to the original position. The ratchet does not reverse due to the elastic pin acting as a brake.
在所述交接卡爪4的端部弹性偏置有预活动块46,由于受交接卡爪厚度的限制,不能选择直径与线径较大的压簧,为达到所需力的要求,优选的,交接卡爪4包括两个压簧47,两个所述压簧47顶靠所述预活动块46。由两个交接卡爪和一个旋转基板构成一条旋转臂,旋转臂可以与动力及其传递装置的法兰联轴器相连,构成一个基本的旋转单元。A
相邻两组旋转基板3上的交接卡爪满足上述旋转基板在转动时,两相邻的交接卡爪之间轨迹重合,也即,两交接卡爪之间预活动块和触发推板之间轨迹重合,且两交接卡爪之间卡口的位置能够连通。The transfer claws on the adjacent two groups of rotating
所述交接卡爪的交接过程工作原理如下:当两个交接卡爪(交接卡爪A和交接卡爪B)在即将交接时,它们的轨迹即将重合。交接卡爪A的预活动块会将交接卡爪B的触发推板沿着其底板的滑槽向前推。由于推动了触发推板,柔性绳拨动棘轮转过180度,与棘轮相连的曲柄滑块状态发生了改变。交接卡爪B将由原来的开放状态变为闭合状态,对车辆停放篮的轴端实现夹持效果。相对的,B的预活动块也对交接卡爪A有相同的作用,交接卡爪 A将由原来的闭合状态变为开放状态,取消对轴端的夹持,此时轴部从从交接卡爪A交接至交接卡爪B,交接完成。The working principle of the handover process of the handover claws is as follows: when two handover claws (handover claw A and handover claw B) are about to be handed over, their trajectories are about to coincide. The pre-moving block of the handover claw A will push the trigger push plate of the handover claw B forward along the chute of the bottom plate. As the trigger push plate is pushed, the flexible rope toggles the ratchet wheel through 180 degrees, and the state of the crank slider connected to the ratchet wheel changes. The handover jaw B will change from the original open state to the closed state, and achieve the clamping effect on the shaft end of the vehicle parking basket. On the contrary, the pre-moving block of B also has the same effect on the handover claw A. The handover claw A will change from the original closed state to the open state, and the clamping of the shaft end will be cancelled. It is handed over to the handover jaw B, and the handover is completed.
尽管本申请中直接通过相邻两交接卡爪其中一交接卡爪的端部与另一交接卡爪的触发推板也能够实现本发明的技术目的,然而申请人发现在交接过程中,处于交接中的轴端可能会被正在处于上升状态的活动板卡死。引起上述现象的主要原因是由于活动板的移动与触发推板的移动是同步进行的,是一个相互关联的运动过程。因此本发明中设置了预活动块。预活动块位于交接卡爪的顶部,用来在交接过程中推动另一交接卡爪的触发推板。预活动块后方装有压簧。运动阶段如下:初始阶段:卡爪B对轴端处于夹持状态,卡爪A处于开放状态。现欲将卡爪A与卡爪B交接,互相改变卡爪的状态。Although in the present application, the technical purpose of the present invention can also be achieved by directly using the end of one of the two adjacent handover claws and the triggering push plate of the other handover claws, the applicant found that during the handover process, during the handover process, the The end of the shaft may be caught by the movable plate that is in the ascending state. The main reason for the above phenomenon is that the movement of the movable plate and the movement of the trigger push plate are synchronized, which is an interrelated movement process. Therefore, a pre-active block is provided in the present invention. The pre-movement block is located on the top of the handover jaw and is used to push the trigger push plate of the other handover jaw during the handover process. A compression spring is installed behind the pre-moving block. The movement stages are as follows: Initial stage: Claw B is in a clamping state for the shaft end, and Claw A is in an open state. Now we want to hand over the claw A and the claw B, and change the state of the claw mutually.
第一阶段:交接卡爪B的预活动块接触到需要交接的卡爪A中的触发推板,并将其往前推动,活动板开始往里收缩。The first stage: The pre-moving block of the handover claw B contacts the trigger push plate in the claw A that needs to be handed over, and pushes it forward, and the movable plate begins to shrink inward.
第二阶段:随着运动的进行,交接卡爪A的预活动板也触碰到交接卡爪B的接触推板并将其往前推动,同时卡爪B的活动板向外伸出,抵住了正在交接的轴端。Stage 2: As the movement progresses, the pre-moving plate of the handover jaw A also touches the contact push plate of the handover jaw B and pushes it forward. Holds the end of the shaft that is being handed over.
第三阶段:交接卡爪B的预活动块开始压缩其后部的压簧,使交接卡爪A能带动轴端在被卡爪B抵住的情况下继续向内运动一段距离。The third stage: the pre-moving block of the handover claw B begins to compress the compression spring at the rear, so that the handover claw A can drive the shaft end to continue to move inward for a certain distance under the condition of being resisted by the claw B.
第四阶段:交接卡爪的活动板越过轴端,活动阻力消失。由于两压簧提供的最小弹力大于拉簧的最大弹力,交接卡爪B中被压缩的压簧复位,依靠弹力继续推动交接卡爪A 的触发推板直到其行程末尾。The fourth stage: The movable plate of the handover jaw passes over the shaft end, and the movable resistance disappears. Since the minimum elastic force provided by the two compression springs is greater than the maximum elastic force of the tension spring, the compressed compression spring in the transfer claw B resets and continues to push the trigger push plate of the transfer claw A until its stroke ends.
通过预活动块的设置解决了在交接时卡爪与轴端会发生卡死的情况,使交接这一过程能够顺利进行。同时由于预活动弹簧置于卡爪的顶部,与把弹簧安装在活动板处的传动设计相比,提升了活动板的刚性和强度,使交接卡爪更加坚固可靠。另外,顶部的预活动弹簧在交接完成后还可以缓冲交接卡爪中的活动部件,在发生偏转过度等危险情况时保护装置,提升安全性能。The setting of the pre-moving block solves the problem that the jaw and the shaft end will be stuck during the handover, so that the handover process can be carried out smoothly. At the same time, since the pre-moving spring is placed on the top of the jaw, compared with the transmission design in which the spring is installed at the movable plate, the rigidity and strength of the movable plate are improved, and the handover jaw is more firm and reliable. In addition, the pre-moving spring on the top can buffer the moving parts in the handover jaw after the handover is completed, protect the device in the event of dangerous situations such as excessive deflection, and improve the safety performance.
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应该了解,本发明不受上述实施例的限制。本申请中上述实施例和说明书中描述的只是本发明的原理,在不脱离本发明精神和范围的前提下本发明还会有各种变化和改进。上述变化和改进都落入要求保护的本发明的范围内。The foregoing has shown and described the basic principles, main features and advantages of the present invention.
