The utility model discloses a transverse moving device which comprises two C-shaped frames, a lead screw rectangular pipe is arranged between the two C-shaped frames, universal wheels are arranged at the two ends of the lower walls of the two C-shaped frames, a supporting mechanism is arranged between the two C-shaped frames and the ground, and two force arm rods are symmetrically and movably arranged on the side wall of one side of the lead screw rectangular pipe. A hydraulic cylinder and an enclasping limiting piece are connected between the two force arm rods, round pipes are rotationally arranged on the side walls of the two force arm rods correspondingly, the other ends of the two round pipes are connected with an airplane wheel limiting plate, and two first rollers and two second rollers are rotationally arranged between the force arm rod and the airplane wheel limiting plate which are located on the same side correspondingly. And a manual pump is mounted on the side wall of the other side of the screw rod rectangular pipe, and the manual pump and the hydraulic cylinder are arranged in a matched mode. The utility model relates to the technical field of transverse movement of unmanned aerial vehicles. According to the transverse moving equipment, the hydraulic rods in the hydraulic cylinders contract to drive the airplane wheel limiting plates to be lifted through oil return of the manual pumps, and stable holding and lifting of the unmanned airplane wheels are achieved.

The utility model discloses a brake with a friction plate convenient to replace, which belongs to the technical field of brake friction plate replacement, and comprises an adjusting component, a mounting component, a base and a brake drum, the adjusting component is arranged in the brake drum, the mounting component is arranged on the surface of the adjusting component, and the base is arranged on the mounting component. The brake drum is rotationally connected to the front side of the base, through arrangement of the adjusting assembly, the adjusting assembly can be connected with the mounting assembly, the effect of adjusting the mounting assembly can be achieved, and therefore the brake effect can be achieved by being matched with the mounting assembly for use; by means of the installation assembly, the effect of conveniently disassembling, replacing and installing the friction plate can be achieved, and therefore the problems that the replacement process of an existing brake friction plate is usually complex and time-consuming, a large number of assemblies need to be disassembled, and even special tools are needed sometimes, due to the inconvenience, the maintenance cost is increased, and other components are possibly damaged due to misoperation are solved.

The application belongs to the field of discharge devices, and particularly relates to a high-sealing-discharge system. The existing cylinder structure cannot accurately control the position of a discharge door plate. After the cylinder is broken, the piston rod is retracted, which leads to a poor sealing of the discharge port and easy leakage. The present application provides the following scheme. The application comprises a cylinder, one side of the cylinder is provided with a discharge port, the other side is provided with a mounting port, the outer wall of the cylinder at the mounting port is provided with a mounting bracket, the mounting bracket is provided with a servo motor and a planetary reducer, the output end of the planetary reducer is connected with a threaded advancing rod, and the mounting port is provided with an anti-rotation rod. In the application, under the driving of the servo motor, the anti-rotation rod drives the material pushing door plate to make horizontal accurate movement, the opening and closing of the cylinder discharge port are realized, the first wear-resistant sleeve is fixed by using a fixing assembly, the sealing property of the device is improved, and the sealing property of the device is further improved by the abutting of the first rubber pad, the second rubber pad and the cylinder.
