Rail butt joint combined connecting sleeve
The present invention discloses a rail butt joint combined connecting sleeve, which comprises a fixing clamping sleeve and a top plate, wherein a rail bottom plate clamping groove is formed in one side of the fixing clamping sleeve, a boss is arranged on the other side of the fixing clamping sleeve, a rail bottom plate bayonet is formed in the top plate, the top plate is arranged on one side of the boss in the fixing clamping sleeve, a top plate jacking screw hole is formed in the boss, and a top plate jacking screw rod is arranged in the screw hole. The invention has the following technical effects. The rail butt joint is reinforced to be fixed; when transportation equipment such as a mine car or a shuttle car is braked on the rail; the clamping jaws are not affected to pass through, therail butt joints are not prone to deformation or dislocation, derailing accidents are prevented, the pre-tightening force of the threaded fasteners enables the rail to generate pre-pressure and make close contact with the contact faces of the fixing clamping sleeve and the top plate, so that the rail can be prevented from loosening and resist deformation. The rail is not required to be reamed or asteel plate is not required to be welded on the rail, so that the rail laying workload is reduced, the rail laying period is shortened, and the rail laying cost is reduced.
本发明公开了一种轨道对接接头组合连接套，包括固定卡套、顶板，在固定卡套一侧有轨道底板卡槽，在固定卡套另一侧有凸台，顶板开有轨道底板卡口，顶板设在固定卡套内凸台一侧，在凸台上开有顶板顶紧螺孔，在螺孔中有顶板顶紧螺杆。本发明有如下技术效果，强化轨道对接接头处固定，当矿车或梭车等运输设备在轨道制动时，一是不影响抱爪的通过，二是轨道对接接头处不容易变形错位，防止脱轨事故的发生，螺纹紧固件的预紧力使轨道与固定卡套及顶板的各接触面间产生预压力并紧密接触，可以防止轨道松动并抵抗变形。无需对轨道进行扩孔加工或在轨道上加焊钢板，减少了铺轨工作量，缩短了铺轨工期，从而降低了铺轨成本。
