Prestress tensioning operation device and working method
The invention discloses a prestress tensioning operation device and a working method. The prestress tensioning operation device comprises a rectangular frame, a rail parallel to the width direction of a cover beam is arranged above the frame, a movable crown block is arranged on the rail, an electric hoist is connected to the lower portion of the crown block, a jack is connected to the lower portion of the electric hoist, and encoders are arranged on motors of the crown block and the electric hoist. The encoder is used for recording the position and the speed of the motor, and accurate positioning of the moving direction of the crown block and the up-down direction of the electric hoist of the device is achieved, the vertical moving mechanism is arranged on the crown block, the horizontal moving mechanism is arranged on the vertical moving mechanism, and a three-axis system is formed by the vertical moving mechanism, the horizontal moving mechanism and the encoder. The pre-stress hole positioning device can automatically position the position of a pre-stress hole and automatically place a jack to a corresponding position, so that the participation of manpower is saved, the labor intensity of workers is reduced, and the time is saved.
一种预应力张拉操作装置及工作方法，包括矩形框架，在框架上方设有平行于盖梁宽度方向的轨道，在轨道上设置有可移动的天车，在天车下方连接有电动葫芦，在电动葫芦下方连接有千斤顶，在天车和电动葫芦的电机上都设置有编码器，编码器用于记录电机的位置和速度，实现设备的天车移动方向和电动葫芦的上下方向的精确定位，由于本发明设置了一种预应力张拉操作装置，通过在天车上设置垂直移动机构，在垂直移动机构上设置水平移动机构，三者组成3轴系统，能够自动定位预应力孔的位置，并自动把千斤顶放到相应位置，节省了人力的参与，降低的人工的劳动强度，节省了时间。
