A blocking device for a power transport device

Abstract

The invention discloses a blocking device used for a power transportation device. The blocking device comprises a horizontal pulley, a vertical pulley, pulleys, hydraulic swing rods, springs, rope guiding devices, a left cone pulley, a force sensing motor, a right cone pulley, a linkage shaft and a blocking rope. The horizontal pulley, the vertical pulley and the rope guiding devices are respectively connected to the ground. The pulleys are arranged at the upper ends of the hydraulic swing rods. The lower ends of the hydraulic swing rods are connected to the ground. One end of each spring is connected to the lateral side of the corresponding hydraulic swing rod. The other end of each spring is connected to the ground. The left cone pulley and the right cone pulley are connected to the left end and the right end of the linkage shaft respectively. One end of the linkage shaft is connected with a driven gear. A universal driving shaft of the force sensing motor is connected with a one-way gear which is meshed with the driven gear. A passive gear is connected with the driven gear. The blocking rope sequentially penetrates through the left cone pulley, the rope guiding devices, the pulleys, the vertical pulley, the horizontal pulley and the right cone pulley to form a blocking frame. By means of the blocking device, the speed of the power transportation device in the advancing process is effectively decreased, and controllability of the speed is achieved.

Description

technical field [0001] The invention relates to the field of carrier-based aircraft, in particular to a blocking device for a power transport device. Background technique [0002] At present, the carrier-based aircraft or aircraft landing aid systems of major countries in the world are mainly arresting cables. It cannot meet the requirements of the carrier-based aircraft's landing glide distance, so external forces must be used to help it land. [0003] On high-speed highways, long and steep slopes are often built in special sections as emergency parking deceleration belts; and deceleration belts only cause vehicles to hit places where there is no one, and eventually they will collide with obstacles, causing vehicle losses. [0004] Elevators have become an important means of transportation in people's lives; there are often news reports that elevators will get out of control and drop rapidly, which will easily cause people's psychological harm, and they will not dare to ta...

[0008] The patent number is CN201120170242.7, and the name is a new type of anti-descent device for carrier-based aircraft. There are chute at both ends, and the upper end of both sides of the chute is provided with notch pressure plate, which is embedded in the deck; the cross section of the resistance slider is "C" shape, and the upper end is provided with a comb-shaped anchor ball slot, and the lower end is equipped with an electromagnetic Iron, and installed in the chute at the end of the deck; the hanger is composed of a sleeve, a rope, an anchor ball, and a connecting plate. One end of the connecting plate is connected to the aircraft, and the other end is connected to the sleeve; mouth, vacuum nozzle, rope fixing hole, anchor ball socket; the anchor ball socket is provided with an anti-retreat groove; the rope is installed inside the sleeve, one end is connected to the rope fixing hole, and the other end is connected to the anchor ball; The anchor ball is installed in the anchor ball socket, and the anti-retreat rolling pin on it is connected with the anti-retreat groove. This structure is complicated and inconvenient to use
