The invention discloses jacking equipment for bridge construction. The jacking equipment structurally comprises a base, a switch, an oil pump, a pressure gage, a liquid supply pipe and a jacking device, wherein the upper side of the front end of the base is fixedly connected with the lower side of the switch in an embedded mode, the oil pump is in bolted connection with the upper side of the middle of the base, the pressure gage is fixedly connected with the upper side of the left end of the base in an embedded mode, the liquid supply pipe is connected between the pressure gage and the jackingdevice, the jacking device is located at the left side of the base and comprises an outer ring, a jacking rod and an auxiliary device, and the right side of the outer ring is in threaded connection with the liquid supply pipe. According to the jacking equipment, chucks of clamping rods fixed to the inner side of a sleeve are pushed into the inner side of the sleeve in the way that push springs atthe outer sides of fixed rods abut against limiting blocks to clamp the jacking rod, excessive local pressure of a bridge caused by a sudden fault of the jacking device is prevented, and therefore the safety coefficient of construction is increased; sealing layers extrude ejector blocks to push push-rods when the bridge descends, so that attaching blocks are mutually attached, and the pressure buffering of the attaching blocks to the bridge is increased through static friction force.
本发明公开了一种桥梁施工用顶升设备，其结构包括底座、开关、油泵、压力表、供液管、顶升器，底座前端上侧与开关下侧嵌固连接，油泵与底座中部上侧螺栓连接，压力表与底座左端上侧嵌固连接，供液管连接在压力表与顶升器之间，顶升器位于底座左侧，顶升器包括外环、顶升杆、辅助器，外环右侧与供液管螺纹连接通过套筒内侧固定的卡杆将卡头通过固定杆外侧推簧抵着限位块推入套筒内侧对顶杆进行卡动，防止了顶升器突然出现故障造成的桥梁局部压力过大，提高了施工的安全系数，密封层在桥梁下降时挤压顶块推动推杆使得贴合块相贴合通过静摩擦力增加贴合块对桥梁的压力缓冲。
