一种方舱升降机构 A cabin lifting mechanism
技术领域 本发明涉及一种升降机构, 特别涉及一种用于方舱从载车上卸下、 或者装 载入载车内的方舱升降机构。 背景技术 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting mechanism, and more particularly to a cabin lifting mechanism for removing a shelter from a vehicle or loading it into a vehicle. Background technique
方舱的结构类似于集装箱, 通常由金属板材焊接而成, 通常方舱均配备有 载车, 通过载车运载到所需的地方, 其标准也是参考集装箱标准制定的, 与集 装箱相比, 具备更高的机动性能。 The structure of the square cabin is similar to that of a container. It is usually welded by sheet metal. Usually, the cabin is equipped with a carrier and carried by the vehicle to the required place. The standard is also based on the container standard. Higher maneuverability.
现有的方舱大多采用直接起吊的方式进行装载或卸下, 不仅操作繁琐、 耗 时长, 而且还需依赖于起重设备, 才能完成装卸操作, 针对上述问题, 通常在 方舱的四周设置升降装置, 并借助该升降装置的对方舱的离地高度进行调节, 实现方舱的自升降, 最后通过升降装置底部与地面接触, 支撑起整个方舱。 Most of the existing square cabins are loaded or unloaded by direct lifting. Not only is the operation cumbersome and time consuming, but also depends on the lifting equipment to complete the loading and unloading operation. For the above problems, the lifting and lowering of the cabin is usually arranged. The device is adjusted by the height of the ground of the opposite cabin of the lifting device to realize self-lifting of the cabin, and finally the bottom of the lifting device is in contact with the ground to support the entire cabin.
例如 1990年第 04期的 《电子机械工程》 中第 30页〜第 37页, 《S5T方舱 升降机构的设计》一文中公开的方舱升降机构, 上述升降装置通常用销轴铰接 在方舱侧面, 并以合页的形式实现收放, 采用这样的结构虽可在运输时折叠收 纳升降装置, 以减小方舱在运输过程中的整体宽度, 但操作效率低、 机动性不 佳, 当方舱从载车上卸载时, 需另行将升降装置从方舱的侧面展开, 然后才沿 竖向下放出支撑杆, 增加了方舱卸载时所需的操作时间, 不利于方舱的快速部 署。 For example, in the "Electrical Mechanical Engineering", No. 04, 1990, from page 30 to page 37, the cabin lifting mechanism disclosed in the article "Design of the S5T Cabin Lifting Mechanism", the lifting device is usually hinged to the cabin with a pin. The side surface is retracted in the form of a hinge. Although such a structure can be folded and stored in the transportation to reduce the overall width of the cabin during transportation, the operation efficiency is low and the mobility is poor. When the cabin is unloaded from the vehicle, the lifting device needs to be separately deployed from the side of the cabin, and then the support rod is released vertically downwards, which increases the operation time required for the unloading of the cabin, which is not conducive to the rapid deployment of the cabin.

When the movable end of the strut is placed inside the bayonet, the strut and the connecting rod are perpendicular to each other. . With such a structure, compared with the existing planar quadrilateral mechanism, compared with the manner in which the pin is locked to form a dead rod, the card-type cooperation between the bayonet and the movable end of the strut is convenient for disassembly and assembly, and the operation is safer. It is not easy to wring the operator during the loading process.

Compared with the prior art, the beneficial effects of the present invention are as follows:
1、 升降的操作时间更短, 升降效率高: 第一, 通过链轮链条传动, 相比于 齿轮齿条、 丝杆螺母等方式, 传动速率更快。 第二, 区别于现有技术中, 仅通 过直线传动机构沿竖向伸縮支撑杆完成整个高度部分升降的方式, 本发明中通 过平行四边形机构中的机架 (即本发明中的舱体) 与摇杆 (即本发明中的套筒)
在向下展开过程中沿竖向的相对移动代为完成其中一部分高度 (大致三分之一 的高度) 的升降, 在这一部分高度升降速度尤其迅捷, 操作时间短, 且升降效 率高。 1. The lifting operation time is shorter, and the lifting efficiency is high: First, through the sprocket chain transmission, the transmission speed is faster than that of the rack and pinion and the screw nut. Secondly, different from the prior art, only the linear telescopic mechanism completes the lifting and lowering of the entire height portion along the vertical telescopic support rod. In the present invention, the frame in the parallelogram mechanism (ie, the cabin in the present invention) is Rocker (ie sleeve in the present invention) In the downward development process, the relative movement in the vertical direction is performed to complete the elevation of a part of the height (approximately one-third of the height), in which the height is particularly fast, the operation time is short, and the lifting efficiency is high.
2、 升降时更省力: 第一, 通过减速机内的齿轮变速调整传动比, 操作时更 加省力; 第二, 由于平行四边形机构代为完成的一部分升程, 此部分操作无需 持续操作人员手摇, 操作人员展开即可, 操作更加省力。 2. It is more labor-saving when lifting: First, adjust the transmission ratio through the gear shifting in the reducer, which is more labor-saving during operation. Second, because the parallelogram mechanism performs a part of the lift, this part of the operation does not need to be continuously operated by the operator. The operator can expand and the operation is more labor-saving.
3、 机构可靠, 操作安全: 第一, 由于采用了链条链轮机构, 与现有的丝杆 螺母副、 齿轮齿条机构等方式相比较, 更不易出现卡死的情况, 尤其适用于风 沙等恶劣环境下使用, 可靠性更佳。 第二, 通过将楔形撑杆与连杆的卡口相互 卡接、 并通过锁具自锁的方式, 替代现有的插销钉的方式, 锁紧操作不易误伤 操作人员, 安全性能更好。 第三, 通过具有止逆功能的驱动电机与链条配合, 可实现在升降过程中暂停、 刹车, 实现间歇升降。 第四, 通过可以伸入驱动齿 轮的齿间间隙的锁具, 以类似于儿童锁的方式, 进一步实现机构的自锁, 防止 误操作时机构坍塌, 安全性能更好。 附图说明 图 1为本发明一种实施方式的结构示意图; 图 2为本发明设置连杆以后形成平面四边形机构后的结构示意图; 图 3为本发明设置撑杆以后的结构示意图; 图 4为本发明撑杆可锁死的一种实施方式的结构示意图; 图 5为图 4的局部放大示意图; 图 6为本发明中动力源的一种实施方式的结构示意图;

Secondly, by locking the wedge-shaped strut and the bayonet of the connecting rod and locking the self-locking by the locking device, the existing locking pin is replaced, the locking operation is not easy to accidentally injure the operator, and the safety performance is better. Thirdly, by the combination of the drive motor with the anti-reverse function and the chain, the suspension and braking can be realized during the lifting process, and the intermittent lifting can be realized. Fourthly, the lock can be inserted into the inter-tooth gap of the drive gear, and the self-locking of the mechanism is further realized in a manner similar to the child lock, thereby preventing the mechanism from collapsing during misoperation, and the safety performance is better.
