The invention provides a control device for access and maintenance kiln of a mould platform, in which several sets of supporting wheels are installed on both sides of the lifting platform, a driving device is arranged at the four corners of the lifting platform, a hydraulic rotary push-up device is arranged in the middle of the lifting platform, and a brake spring is arranged on the lower frame of the bottom of the maintenance kiln cabin, which includes a leaf spring, and the leaf spring is arranged parallel to the movement direction of the mould platform. The front end of the brake spring is installed in the front support through the pin shaft, and the rear end is installed in the rear support through the pin shaft; the pin hole of the front support is a long circular hole; the pin hole of the rear support is smaller than the bore diameter of the shaft sleeve, and the bottom of the rear support is provided with a push screw, which bends back from the bottom support to the rear end of the brake spring. Hook, the model first contacts the brake spring at the bottom of the kiln cabin after entering the kiln cabin. The speed of propulsion is decelerated, and the force of collision with the cabin bottom is reduced, thus resolving the problem of the rebound of the model platform.

模台出入养护窑控制装置
本专利技术涉及PC生产线立式窑模台出入养护窑技术,具体是种模台出入养护窑的控制装置。
技术介绍
PC水泥构件养护窑内高温高湿,无法设计驱动装置来控制模台的出入速度,现有技术中,窑体框架为钢制框架,窑体内用于放置模台的舱位内部也无任何防护结构。模台以衡定速度进入舱位,直接进到舱位底部,直到碰到舱位底部挡板停止,底部挡板为钢制构件。由于惯性模台触碰到底部挡板会产生反弹,造成模台前端被弹回窑门处,反弹后的模台的前端处在窑门感应装置感应范围内,感应器到模台位置窑门无法正常关闭,将影响窑门关闭,从而会打乱生产节拍,影响正常生产。
技术实现思路
本专利技术要解决的技术问题是现有的养护窑结构不合理,当模台送入窑内时模台底端触碰窑内底部挡板而反弹,导致窑门不能正常关闭的问题。本专利技术为解决上述技术问题,提供一种模台不回弹的入窑机构,其具体技术方案是:一种模台出入养护窑控制装置,其升降平台两侧的安装有若干组支撑轮,升降平台四角位置分别设有一台驱动装置,升降平台中部设有液压旋转顶推装置,养护窑舱位底部下侧框架上设有制动弹簧,该制动弹簧包括一根板簧,板簧平行于模台运动方向设置,板簧两端制成回弯钩的形状,回弯钩内装有轴套;制动弹簧前端通过销轴安装在前支撑中,后端通过销轴安装在后支撑中;所述前支撑的销轴孔为长圆孔;所述后支撑的销轴孔小于轴套孔径,后支撑底部设有顶推螺杆,该顶推螺杆从底部支顶制动弹簧后端回弯钩。本方案模台在进入窑舱内部后底端先接触制动弹簧,推进速度得到减速,减小与舱底板碰撞的力,从而解决模台反弹的问题。优选的,所述销轴伸出销轴孔的尾端设有销钉孔, ...
