The invention relates to a track reverse pressing wheel device. The track reverse pressing wheel device comprises clamping support blocks, a bearing shaft, reverse pressing wheels, a compression spring and a connecting bolt. Axial through holes are formed in the middles of the clamping support blocks. Upper through holes are designed in the upper ends of the clamping support blocks. Lower throughholes are designed in the lower ends of the clamping support blocks. The upper ends of the clamping support blocks are rotationally provided with the reverse pressing wheels through the bearing shaft.Totally two clamping support blocks are designed. The two clamping support blocks are arranged in a crossed manner. The middles of the two clamping support blocks are rotationally connected in the manner that a rotation shaft penetrates through the axial through holes. The connecting bolt sequentially penetrates through the lower through holes of the clamping support blocks and the compression spring from one side, and the penetrating end portion of the connecting bolt is locked through a nut. The track reverse pressing wheel device has the advantages that design is simple, usage is convenient, the corresponding included angle of the two clamping support blocks is adjusted by adjusting the tension of the compression spring, accordingly, the stress of the reverse pressing wheels and an I-shaped track is adjusted, a trolley is protected against sliding when heavy objects are hoisted, and danger is avoided.

    本发明涉及一种轨道反压轮装置,它包括夹紧支块、轴承轴、反压轮、压缩弹簧、连接螺栓,夹紧支块中间开有轴向通孔,夹紧支块上端设计有上通孔,夹紧支块下端设计有下通孔,夹紧支块上端通过轴承轴旋转安装有反压轮,夹紧支块设计有两个,两个夹紧支块交叉安装且两个夹紧支块中间通过转轴贯穿轴向通孔进行旋转连接,连接螺栓从一侧依次贯穿两个夹紧支块的下通孔以及压缩弹簧且连接螺栓贯穿后的端部通过螺母锁紧。优点是设计简单,使用方便,通过调节压缩弹簧的张力大小调节两夹紧支块的相应夹角,从而调整反压轮与工字型轨道的受力大小,保护小车在起吊重物时不至于溜车发生危险。
