Therefore, they should not be construed as limiting the scope of protection of this application.

[0035] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0036] like Figure 1-2 As shown, the emergency unlocking device 10 includes a left screw 11, a base plate 12, a turbine box 13, a worm gear 14, and a right screw 15.

[0037] In use, the left screw 11 of the emergency unlocking device 10 is installed into the threaded hole at the piston rod head of the actuating cylinder, the base plate 12 is installed onto the fixed seat with screws, and the right screw 15 is engaged with the square hole of the mechanical lock and locked by the connecting piece. When the piston rod of the actuating cylinder cannot be pushed out normally, the emergency unlocking device 10 can be manually operated to open the mechanical lock.

[0038] Under normal operating conditions, the piston rod of the actuator cylinder extends, driving the left screw 11 and right screw 15 to move to the right, thus unlocking the mechanical lock. In case of a malfunction, the piston rod of the actuator cylinder cannot extend normally. It is necessary to turn the worm gear 14 clockwise with a wrench. At this time, the left screw 11 remains stationary, while the right screw 15 moves to the right, unlocking the mechanical lock.

[0039] When the extension L of the right screw 15 is 40mm, 45mm, or 50mm, it is necessary to measure and use a torque wrench with a torque not exceeding 7N·m to turn the worm 14, and the thrust of the right screw 15 should not be less than 3000N.

[0040] In view of the above-mentioned emergency unlocking device 10, this application provides an emergency unlocking device force measuring fixture.

[0041] like Figure 3-4 As shown, the emergency unlocking device force measuring fixture includes a mounting base 1, bolt 2, first nut 3, washer 4, second nut 5, connecting block 6, S-type digital display force gauge 7, screw 8, third nut 9, and digital display torque wrench.

[0042] Specifically, such as Figure 5-6 As shown, the mounting plate 1 is used to simulate the installation and fixation of the emergency unlocking device 10 in actual tooling conditions. The mounting plate 1 is I-shaped and includes a first side plate 101, a horizontal plate 102, and a second side plate 103 welded together. The horizontal plate 102 is located in the middle of the first side plate 101 and the second side plate 103. The first side plate 101 has a threaded hole, and the left screw 11 of the emergency unlocking device 10 is threadedly connected to the first side plate 101. The horizontal plate 102 and the base plate 12 have corresponding mounting holes. The base plate 12 is fixedly connected to the horizontal plate 102 by bolts 2 and a first nut 3.

A square hole adapted to the rectangular section is opened on the side of the rectangular section away from the first threaded section. The center line of the square hole coincides with the center line of the first threaded section. The rectangular section of the right screw 15 is installed in the square hole of the rectangular section, and the rectangular section and the right screw 15 are fixedly connected by a washer 4 and a second nut 5.

[0044] like Figure 10-11 As shown, the connecting screw 8 includes a shorter second threaded section, an assembly section, and a longer third threaded section. The second threaded section is used to connect with the S-type digital display force gauge 7, and the third threaded section is connected with the second side plate 103. In this embodiment, the second side plate 103 has a threaded hole, and the third threaded section is threadedly connected to the second side plate 103. After adjusting the relative position of the connecting screw 8 and the second side plate 103, the third threaded section is fixedly connected to the second side plate 103 by two third nuts 9 located on both sides of the second side plate 103, thereby locking the connecting screw 8. The assembly section is provided with an assembly plane for cooperating with a wrench. The assembly plane is obtained by milling a cylindrical surface, and the assembly section facilitates the wrench to turn the connecting screw 8, thereby realizing the adjustment of the connecting screw 8.

[0045] Furthermore, the S-type digital display force gauge 7 has a first connector and a second connector at both ends, and both the first connector and the second connector have threaded holes. The first connector is threaded to the first threaded section of the connecting block 6, and the second connector is threaded to the second threaded section of the connecting screw 8. The digital torque wrench is used to adjust the maximum torque of the worm gear 14 of the emergency unlocking device 10.
