[0014] Beneficial effects

[0015] The utility model provides a detection device for civil air defense door shape correction equipment. Compared with the existing technology, it has the following advantages:

[0016] (1) The detection device for the civil air defense door correction equipment can drive the second screw to rotate after the power is turned on by the stepping drive motor. At this time, the first set of receiving plates and the second set of receiving plates are in a connected state, which then drives the transmission rod and the first bevel gear to rotate. Through the meshing connection between the first bevel gear and the second bevel gear, the first screw is driven to rotate. The first screw cooperates with the screw sleeve and then converts its own rotational motion into the descending motion of the screw sleeve. The lifting plate then drops to the bottom, making it convenient for the detection personnel to place the civil air defense door to be detected. The stepping drive motor is driven in the reverse direction, which then drives the screw sleeve and the lifting plate to rise.

[0017] (2) The detection device used in the civil air defense door shape correction equipment disconnects the connection between the first set of connecting plates and the second set of connecting plates by pulling out the latch, and then starts the stepper drive motor again. The second screw rotates and then pushes the threaded slide to move horizontally. The flatness detector below then performs an appearance inspection on the civil air defense door to detect whether there is any area that needs to be corrected. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom end of the screw sleeve 215 is fixedly connected to a lifting plate 216, and the lifting plate 216 is slidably connected along the lower part of the portal frame 1; through the meshing connection between the first bevel gear 212 and the second bevel gear 213, the first screw 214 is driven to rotate, and the first screw 214 cooperates with the screw sleeve 215 to convert its own rotational motion into the lifting motion of the screw sleeve 215.

[0026] The driving assembly 22 is disposed on a side of the portal frame 1 opposite to the transmission assembly 21 and is used to drive the transmission rod 211 to rotate.

[0027] In this embodiment, the driving component 22 includes a stepper drive motor 221 fixedly mounted on the outer wall of one side of the portal frame 1. The portal frame 1 is located on the inner wall on the same side of the stepper drive motor 221 and is rotatably mounted with a second screw 222. The power output end of the stepper drive motor 221 is connected to the power input end of the second screw 222. When the stepper drive motor 221 is powered on, it can drive the second screw 222 to rotate.

[0028] In this embodiment, a first set of connecting plates 3 is welded to one end of the transmission rod 211, and a second set of connecting plates 4 is welded to the end of the second screw rod 222. The first set of connecting plates 3 and the second set of connecting plates 4 are detachably connected by inserting a bayonet into the docking hole.

[0029] In this embodiment, a receiving block 8 is fixed to the lower surface of the top end of the portal frame 1 , and the second screw rod 222 passes through the receiving block 8 and is rotatably connected thereto, so that the second screw rod 222 rotates more stably.

[0030] In this embodiment, a threaded slide 5 is threadedly connected to the second screw 222, and the upper part of the threaded slide 5 is close to the lower wall of the door frame 1. A flatness detector 6 is fixedly installed on the lower end of the threaded slide 5. The stepper drive motor 221 is started, and the second screw 222 is rotated to push the threaded slide 5 to move horizontally. The flatness detector 6 below then performs an appearance inspection on the civil defense door to detect whether there is any place that needs to be adjusted.

[0031] In this embodiment, a counterweight block 7 is fixedly installed on the upper part of the lifting plate 216 close to the transmission component 21, so that the center of the lifting plate 216 is maintained on the side of the transmission component 21, so that the lifting plate 216 can be raised and lowered more stably.
