Active pressure applying type gapless sliding block expansion joint device for suspension type monorail track beam
The invention discloses an active pressure applying type gapless sliding block expansion joint device for a suspension type monorail track beam, the suspension type monorail track beam comprises a top plate, a web plate and a bottom plate, and the gapless sliding block expansion joint device comprises a trapezoidal sliding plate, a lower plate and a spring mechanism. The trapezoid sliding plate is integrally in an isosceles trapezoid shape and arranged between the bottom plates on the two sides of the expansion joint, and the trapezoid sliding plate is connected through the lower plate. The trapezoidal sliding plate is arranged in a notch in the end of the bottom plate, and the bottom plate is provided with an inclined sliding way making contact with the bevel edge of the trapezoidal sliding plate, so that sliding connection is achieved through the inclined sliding way and the bevel edge of the movable plate. And the spring mechanism is used for pressing each bevel edge of the trapezoidal sliding plate on the oblique slide way on the corresponding side all the time, so that the trapezoidal sliding plate moves along with the change of the width of the expansion joint. The driving face is smoother, potholes caused by gaps can be almost eliminated, noise can be effectively reduced, the expansion joint with the large application range can be effectively reduced, and steel can be saved.
本发明公开了一种悬挂式单轨轨道梁主动施压式无间隙滑块伸缩缝装置，所述悬挂式单轨轨道梁包括顶板、腹板和底板，无间隙滑块伸缩缝装置包括梯形滑动板、下板和弹簧机构，梯形滑动板整体呈等腰梯形并且设置在伸缩缝两侧的底板之间，梯形滑动板通过下板承接；梯形滑动板设置在底板端部的缺口内，底板上设置有与梯形滑动板的斜边接触的斜向滑道，从而通过斜向滑道与活动板的斜边实现滑动连接；弹簧机构用于将梯形滑动板的各斜边始终压紧在对应侧的斜向滑道上，以使梯形滑动板随着伸缩缝的缝宽变化而移动。本发明的行车面更加平整，几乎可以消除缝隙带来的坑洼感，可有效减小噪声及适用范围较大的伸缩缝，而且还可以节约钢材。
