Pluggable and replaceable bridge expansion and contraction device
The invention relates to the field of bridge expansion and contraction devices, and especially relates to a pluggable replaceable bridge expansion and contraction device. Inserting holes are matched with inserting rods in an inserting manner, so a connecting plate can be mounted in a rectangular groove, a telescopic body is connected to the top end of an adjusting screw, through an auxiliary rod clamped in an adjusting screw hole and under matching of bearings, the adjusting screw is driven to rotate, the adjusting screw rod is in threaded fit with a thread sleeve, and the telescopic rod is driven to move downwards until a supporting rod is in contact with the connecting plate, so the telescopic body is conveniently installed; in the downward moving process of the telescopic body, a springcompresses the supporting plate, an upward supporting trend is provided for the telescopic body, when a vehicle passes through the upper portion, the supporting strength of the telescopic body can beimproved, and when the telescopic body needs to be replaced and maintained, only the adjusting screw needs to be reversed, the telescopic body is taken out, meanwhile, the spring has pushing force onthe telescopic body in the process, and the telescopic body is convenient to detach.
本发明涉及桥梁伸缩装置领域，具体涉及一种可抽插更换式桥梁伸缩装置，在插孔和插杆的插接配合下，可以将连接板安装在矩槽内部，将伸缩主体连接在调节螺杆顶端，通过卡接在调节螺孔上的辅助杆，在轴承的配合下，带动调节螺杆转动，利用调节螺杆和螺套的螺纹配合，驱动伸缩主体下移，直至支撑杆和连接板接触，便于伸缩主体的安装，在伸缩主体下移的过程中，弹簧压缩支撑板，对伸缩主体提供一个向上的支撑趋势，当上部有车辆经过时，可以提高对伸缩主体的支撑强度，当需要对伸缩主体进行更换维修时，只需要反转调节螺杆，将伸缩主体带出即可，同时过程中弹簧对伸缩主体有个推动力，便于伸缩主体的拆出。
