[0026] From above Figure 1-3 It can be seen that the detection device for the axial movement of the straightening roller and the gantry designed in this embodiment include a frame hydraulic nut 1, an operating side shaft head and assembly 2, a tie rod 3, a transmission side shaft head and assembly 4, a distance ring 5, a threaded sleeve 6, a thrust bearing 7, a gantry 8, and a hydraulic jack 9. The operating side shaft head and assembly 2 and the transmission side shaft head and assembly 4 are fixed to the frame through a pressure plate. The frame is a welded part, and the frame anchor plate is fixed to the foundation by bolts. The frame serves as the main support carrier and bears all the loads of the straightening machine.

[0027] Among them, the operating side shaft head and assembly 2 are installed in the operating side bearing seat of the frame; the transmission side shaft head and assembly 4 are installed in the transmission side bearing seat of the frame; one end of the pull rod 3 is installed on the transmission side shaft head, and the other end of the pull rod passes through the operating side shaft head and assembly, and the end of the pull rod passing through is locked by a hydraulic nut to achieve the straightening function. The operating side shaft head and assembly 2 and the transmission side shaft head and assembly 4 are fixed to the frame through a pressure plate.

[0028] The distance ring 5 contacts the two end faces of the threaded sleeve 6 to position the threaded sleeve 6. The inner ring of the threaded sleeve 6 is connected to the outer ring of the thrust bearing 7 with external threads, and the axial position of the outer ring of the thrust bearing 7 can be adjusted by the adjustment mechanism, thereby adjusting the clearance of the thrust bearing 7.

In the gantry 8 group, a dial indicator is selected to meet the accuracy requirements. When the driving cylinder is started, the axial movement of the end of the pull rod can be detected by the dial indicator.

[0030] Specifically, the detection method is to use the support beam of the gantry 8 as a fulcrum, and use the hydraulic jack 9 to push the assembly where the tie rod is located to the bottom of the operating side; in this process, the movement of the assembly where the tie rod is located is measured by a dial indicator, and this value is the gap value to be measured. More preferably, the operating side frame shaft head is used as a fulcrum, and the assembly where the tie rod is located is pushed to the bottom of the transmission side by the hydraulic jack 9; Figure 1 The hydraulic cylinder in the middle position is shown; then the supporting beam of the gantry 8 is used as the fulcrum, and the assembly where the pull rod is located is pushed to the bottom of the operating side by the hydraulic jack 9. In this process, the movement of the assembly where the pull rod is located is measured by a dial indicator, and this value is the gap value to be measured. The detection method mentioned in the utility model is reliable and practical, the gantry 8 has a novel structure and perfect functions, and can meet the needs of detecting the axial movement of the upper and lower straightening rollers. The gantry 8 has low cost and high rigidity, and has excellent market appeal.
