[0002] The main purpose of photoelectric turret dismounting and mounting equipment is to ensure the dismounting and mounting maintenance requirements of the photoelectric turret under the machine belly of the aircraft. The current photoelectric turret dismounting and mounting equipment mainly uses a scissor-type lifting mechanism to complete the height lifting of the photoelectric turret in cooperation with a hydraulic actuator cylinder. When dismounting and mounting the photoelectric turret, an auxiliary mounting disc is installed, and the mounting disc is connected with the mounting plate on the dismounting and mounting equipment to realize the stable lifting of the photoelectric turret. This dismounting and mounting equipment has a large size and weight, uses a hydraulic actuator cylinder transmission and a traction rod traction movement form, has high maintenance requirements and high cost. Moreover, the current aircraft photoelectric turret has been upgraded in capacity, and the weight and size have increased compared with before. The platform installation and loading and unloading interface have also changed greatly. The original photoelectric turret of the aircraft is connected with the photoelectric turret dismounting and mounting equipment through the mounting plate on the platform. After upgrading, the photoelectric turret is connected with the photoelectric turret dismounting and mounting equipment through a handle. Since the size, weight, and interface of the photoelectric turret after capacity improvement have changed significantly, the opening size of the platform on the original photoelectric turret dismounting and mounting equipment cannot meet the dismounting and mounting requirements of the photoelectric turret after capacity improvement, and a new photoelectric turret dismounting and mounting equipment needs to be designed and improved.

[0005] In the aforementioned equipment of dismounting and mounting of machine belly external hanging object, the two ends of lifting mounting frame are slidably connected with chassis via linear slide rails.

[0006] In the aforementioned equipment of dismounting and mounting of machine belly external hanging object, linear slide rails are bolted on the two side mounting plates of chassis.

[0007] In the aforementioned equipment of dismounting and mounting of machine belly external hanging object, a castor is mounted on chassis.

[0008] In the aforementioned equipment of dismounting and mounting of machine belly external hanging object, chassis is composed of steel pipe and steel plate by welding.

[0009] The ratchet wrench B is bolted with the lug on the bottom frame, so that the hollow screw rod of the ratchet wrench B is fixed on the bottom frame. Advantages

[0010] Compared with the existing photoelectric turret dismounting equipment, the utility model implements weight reduction design, adopts steel pipe welding to complete the bottom frame design, and reduces the length and width of the contour size.

[0011] The original photoelectric turret dismounting equipment adopts wedge block to realize the adjustment of the aircraft heading angle, and the present dismounting equipment is optimized. The screw rod transmission form is adopted, the two sides of the lifting mounting frame are connected through the slide rail and the slide block, the height of the photoelectric turret is adjusted through the ratchet wrench B, and the ratchet wrench A is adjusted, so that the turning of the heading angle at any angle can be realized. Because the auxiliary installation tool of the photoelectric turret is changed from the installation disc to the handle, the present dismounting equipment is optimized, the bracket is designed on the ratchet wrench A, the handle of the turret is docked, and the hole is opened on the bracket, so that short-distance transportation in the field is facilitated; the ratchet wrench and the hollow screw rod are manufactured in cooperation with the navigation mark, so that the equipment is standardized.

[0012] In summary, the utility model adopts a pure mechanical structure to improve the original dismounting equipment, overcomes the problems of large size, large weight and high maintenance cost of the original equipment, realizes the "three-in-one" design concept of the aircraft ground support equipment, and can realize the support demand of the improved photoelectric turret.
