Description

双向机械式千斤顶
技术领域
本实用新型涉及一种机械式千斤顶技术领域，具体地说是一种可控制升降、能顶能拉的双向机械式千斤顶。
背景技术
在工程施工中，经常会有水平方向的顶拉施工需要，因此千斤顶被广泛采用，常用的千斤顶有液压千斤顶或机械千斤顶，液压千斤顶机构优点减少了人力、机械化程度高，缺点是一次性投资大，要有外接电源工地施工不方便，液压系统在冬季或夏季施工队液压油要求高，维修不方便，因而使用受到限制；机械千斤顶采用机械原理，以往复扳动手柄，拔爪即推动棘轮间隙回转，小伞齿轮带动大伞齿轮、使举重螺杆旋转，从而使升降套筒获得起升或下降，而达到起重拉力的功能，目前传统的机械式千斤顶传动效率低，操作费时费力。
发明内容
本实用新型为了克服上述缺陷提供了一种结构合理，操作方便，传动稳定可靠，操作省时省力的双向机械式千斤顶。
 本实用新型采用的技术方案是：一种双向机械式千斤顶，包括底座、顶体和设置在顶体内部的螺杆、套筒、螺母和伞齿轮，伞齿轮与螺杆的杆部连接，套筒通过螺母与螺杆的螺纹部连接，其特征是：螺杆杆部的下段伸入到底座内，在底座内上部、螺杆杆部的外侧设置有平面推力轴承，该平面推力轴承的下方设置有压紧盖，压紧盖的外侧设置有压紧螺母，压紧螺母安装在螺杆杆部的下端，在底座的上方、与伞齿轮之间也设置有平面推力轴承。
本实用新型对底座进行加高、螺杆杆部进行加长，并在底座的上方和底座的内部均设置平面推力轴承，千斤顶的伞齿轮在啮合传动时，平面推力轴承可以使传动更平稳，当伞齿轮的逆向旋转时，使套筒形成平稳下拉的作用，可实现千斤顶的能顶能拉的动作，使操作省时省力，同时还增强了千斤顶的承载能力，延长使用寿命。
附图说明
图1为本实用新型的示意图。
具体实施方式
现结合附图对本实用新型作进一步描述，图1为本实用新型的一种实施例，包括底座10、顶体和设置在顶体内部的螺杆1、套筒2、螺母5和伞齿轮6，伞齿轮6通常为两个相互垂直啮合的伞齿轮6，一个与手柄连接，另一个与螺杆1的杆部连接，套筒2通过螺母5与螺杆1的螺纹部连接，套筒2和螺母5与螺杆1形成丝杠螺母5传动。本实用新型加长了螺杆1杆部的长度，同时加高了底座10的高度，使底座10内部空间加大。螺杆1杆部的下段伸入到底座10内部，在底座10内的上部、螺杆1杆部的外侧设置有平面推力轴承7，该平面推力轴承7的下方设置有压紧盖，压紧盖的外侧设置有压紧螺母11，压紧螺母11安装在螺杆1杆部的下端，可以通过旋转压紧螺母11将该平面推力轴承7与底座10内上壁压紧。在底座10的上方、与伞齿轮6之间也设置有平面推力轴承7，这样，螺杆1在伞齿轮6带动下沿底座10的通孔旋转时，底座10的上下两侧均设置了平面推力轴承7，使传动平稳可靠。
本实用新型需要起升时，通过外力驱动如手柄带动伞齿轮6顺时针转动，伞齿轮6带动螺杆1顺时针转动，螺母5带动套筒2上升顶起重物，实现起升动作；当需要下拉时，旋转压紧螺母11将平面推力轴承7与底座10进行压紧，手柄反向转动使伞齿轮6逆时针转动，伞齿轮6带动螺杆1逆时针转动，螺母5带动套筒2向下移动，在平面推力轴承7作用下，套筒2实现下拉动作。
本实用新型由于在底座10的两侧设置了平面推力轴承7，不仅使螺杆1传动平衡可靠，增强了千斤顶的承载能力，延长使用寿命，而且当伞齿轮6的逆向旋转时，使套筒2形成平稳下拉的作用，可实现千斤顶的能顶能拉的动作，使操作省时省力。
本实用新型具有结构合理，操作方便，传动稳定可靠，操作省时省力的特点。
