Jacking device suitable for heavy support frame structure
The invention discloses a jacking device suitable for a heavy support frame structure. The jacking device comprises a base, an outer sleeve, a jacking screw and a force applying disc, wherein the outer sleeve is rotatably inserted into the base; key grooves are arranged on the middle circumference of the outer side surface at intervals; locking pins are arranged in the key grooves; the locking pins are connected to the outer side surfaces of the outer sleeve in the key grooves through springs; the jacking screw is in threaded connection in the outer sleeve; the force applying disc rotatably sleeves the outer sleeve in the key grooves; an envelope surface of the outer edges of the key grooves is arranged on the inner side surface of the force applying disc; locking grooves are arranged in the circumferential surface of the inner side of the force applying disc at equal intervals; the locking grooves are one-way grooves matched with the locking pins; a handle groove for installing a force applying steel bar is fixedly arranged on the outer side of the force applying disc; and a connecting bolt for fixing the force applying steel bar is arranged in the handle groove. The jacking device is simple in structure and convenient to manufacture, the construction cost is reduced, the construction difficulty is reduced, and the construction safety is ensured while the construction efficiency is improved.
本发明公开了一种适用于重型支撑架结构的顶升装置，包括底座、外套筒、顶升螺杆和施力盘，外套筒转动插接在底座上，外侧面中部圆周上间隔设有键槽，键槽内设锁固销，锁固销通过弹簧连接在键槽内部外套筒的外侧面上，顶升螺杆螺纹连接于外套筒内，施力盘转动套设在键槽处的外套筒上，其内侧面为键槽外缘的包络面，内侧圆周面上均匀间隔开设锁固槽，锁固槽为与锁固销相适配的单向槽，施力盘外侧固定设有安装施力钢棒的手柄槽，手柄槽上设有固定施力钢棒的连接螺栓。本发明结构简单，制作方便，降低了施工成本，减小了施工难度，在提高了施工效率的同时保证了施工的安全。
