The invention discloses a conveniently lifted anti-falling ladder with a more stable center of gravity and relates to the technical field of ladders. The ladder comprises a main ladder, wherein a chute is formed in one side of the main ladder, a pushing device is slidably connected to the inner wall of the chute, a limiting frame is arranged outside the pushing device in a sleeving manner, the limiting frame is fixedly connected to the main ladder, and a supporting plate is rotatably connected to the end at the bottom on one side, close to the chute, of the main ladder. The conveniently liftedanti-falling ladder with the more stable center of gravity can be reinforced automatically when the ladder is likely to overturn backward as the inclination angle becomes small, so that the problem that the ladder is overturned backward as a result of swing is avoided effectively. A constructor moving to the top of the ladder does not consume a lot of physical power, so that the ladder can ascend, and the ladder ascending efficiency is high. In the process that the constructor climbs upward along the ladder, the ladder ascends automatically, so that the construction efficiency is improved. Meanwhile, the ladder is relatively low in demand on physical power and follow-up construction operation is not affected.

The invention relates to a man-powered aircraft with a non-tail wing-in-ground layout, which comprises a fuselage, wings, a pair of end plates, a propeller, a rudder, a landing gear and a man-powered take-off running system. The wings are fixed on the upper part of the fuselage, the end plates are respectively suspended on the outer ends of the two sides of the wings, the propeller, the rudder and the landing gear are respectively arranged on the front end, the rear end and the lower part of the fuselage, and the man-powered take-off running system is respectively in transmission connection with the propeller, the rudder and the landing gear. Compared with the prior art, the invention has the advantages of high lift-drag ratio, small and light structure and simple and practical use.

The invention discloses a semi-electric self-lifting loading and unloading car which comprises a car body, a cargo fork carrier, a hydraulic system and a telescopic trundle frame. The hydraulic system is an electric hydraulic system which is provided with a two-position-four-way reversing solenoid valve, a first oil drainage solenoid valve, a second oil drainage solenoid valve and an oil pump. Two oil outlets of the two-position-four-way reversing solenoid valve are communicated with an upper oil inlet and a lower oil inlet of a double-effect oil cylinder respectively, an oil inlet of the two-position-four-way reversing solenoid valve is communicated with a hydraulic oil tank through a single-way valve and the oil pump, and an oil discharging opening of the two-position-four-way reversing solenoid valve is communicated with the hydraulic oil tank through the first oil drainage solenoid valve. The oil inlet of the two-position-four-way reversing solenoid valve is communicated with the hydraulic oil tank through another oil drainage branch, and the second oil drainage solenoid valve and a throttle valve are arranged in series. Through ingenious arrangement of the solenoid valve hydraulic system, operation such as loading, unloading, car body climbing and car body descending of the whole loading and unloading car can be controlled electrically, the easy degree and labor-saving degree of the operation and working efficiency are greatly improved, and labor intensity is greatly lowered.

The invention belongs to the technical field of high-altitude operations on power transmission lines, and relates to a tool for removing foreign objects at high altitudes on power transmission lines, which includes an insulating rod and an electrothermal cutting part arranged at one end of the insulating rod. The electrothermal cutting part includes a heating head for cutting foreign objects, Temperature control module and power supply to control the temperature of the heating head. On the one hand, the present invention destroys the foreign body structure on the power transmission line through the high temperature of the heating head, and does not need to provide a force point with a larger force arm, which reduces the working radius or working space requirements; The pulling action is basically eliminated, which can reduce the impact of the operation on the strength and safety distance of the transmission line, and prevent the operation from causing obvious mechanical damage to the transmission line or increasing the hidden danger of damage; on the other hand, because of low physical requirements and low segmentation failure rate, The overall working time of operators has been greatly reduced.

The invention discloses a massage physiotherapy manipulator for wax therapy and a use method thereof, specifically relates to the technical field of manipulators, comprising a mounting seat, a movable arm is arranged on the top of the mounting seat, and a pressure component is arranged between the movable arm and the mounting seat , the top of the movable arm is provided with a massage mechanism; the pressure assembly includes a fixed rod, a chute is provided on the outside of the fixed rod, and a linear bearing is sleeved on one end of the fixed rod. The present invention is equipped with a pressure component and a massage mechanism, so that the present invention can effectively save labor costs, and at the same time require less physical strength for the operator, avoiding the problem that the physical strength of the massage operator decreases after working for a long time, resulting in a decrease in massage speed and strength. Simultaneously, the present invention also avoids the problem of wax solidification during the wax treatment process, ensures that the wax can fully contact with the skin, and facilitates the medicinal juice in the wax to be absorbed by the skin, thereby improving the therapeutic effect and ensuring the quality of massage.

The invention relates to an electric wrench for a ground potential insulating operation rod. The electric wrench comprises the insulating operation rod and a charging type wrench. The insulating operation rod comprises an upper connection pipe and a lower connection pipe. The upper connection pipe is connected with the lower connection pipe. A square tenon for installing a hexagonal socket is connected to the upper connection pipe. A connection socket is arranged on the lower connection pipe. A protection sleeve is arranged on the connection socket. The electric wrench has the beneficial effects that operation of the insulating operation rod is achieved through the charging type wrench connected to the insulating operation rod, and compared with existing operation of operators, the strength during work is lowered, the hot-line work efficiency is improved, the electric wrench can adapt to hot weather environments and complex terrain areas, and the requirement for physical power of the operators is lowered during operation; the insulating operation rod is arranged to comprise the upper connection pipe and the lower connection pipe, and compared with an existing single operation rod, the electric wrench has the beneficial effects of being convenient to carry and low in manufacture cost; and fixed connection of the charging type wrench is achieved through the connection socket, and protection is achieved through the protection sleeve.
