Multifunctional rope reeling-off equipment

Abstract

The invention discloses multifunctional rope reeling-off equipment. The multifunctional rope reeling-off equipment comprises a shell, a motor, a coiling block and a pull rope. The motor, the cooling block and the pull rope are arranged in the shell. The motor can drive the coiling block to rotate, the coiling block is sleeved with a circular ring, the circular ring can be rotated around the coiling block, the circular ring is provided with a blocking face, the coiling block is provided with a blocking part, one end of the pull rope is connected to the circular ring, and the pull rope is extended out of the circular ring to be coiled on the coiling block and then is extended out of the coiling block to be connected with a heavy object directly or penetrate through a line slot of a deflection pulley to be connected with a heavy object. The heavy structurally comprises a rubber ball or a fixed pulley or a movable pulley. A cable connected with the motor is extended outwards to be connected with a power source through an electric device element which can be connected or disconnected with the power source.

Description

technical field [0001] The application belongs to a kind of outdoor fire extinguishing, rescue and escape equipment used in the field of buildings. Background technique [0002] Fires in high-rise buildings have always attracted people's attention, and the reliability of fire elevators in the event of a fire is worth pondering. There is also the arm-raising fire truck used in the existing fire-fighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire-fighting ladder truck has a limit. Usually, the fire-fighting ladder truck can only rise to 80 of the limit value. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation, so once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some...

Problems solved by technology

There is also the arm-raising fire truck used in the existing fire-fighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire-fighting ladder truck has a limit. Usually, the fire-fighting ladder truck can only rise to 80 of the limit value. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation, so once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some high-rise buildings have incomplete fire-fighting facilities, fire hydrant doors are blocked by residents with sundries and other phenomena, which bring resistance to fire-fighting and escape

In short, when the height of the ladder truck is not enough, the fire rescue personnel are fully armed and go up the fire floor from the stairs to carry out fire fighting and rescue, which seriously affects the speed and efficiency of rescue and fire fighting. The existing technology has appeared on the roof layer or refuge floor of the building. Set up the rope-releasing equipment. In the event of a fire, the above-mentioned rope-releasing equipment can be controlled to lower the slow-down rope and pull rope for emergency escape. However, the technical solution of the rope-releasing technique has certain safety risks, and also has the disadvantages of relatively complex structure and high cost. It has become necessary to study reliable and safe fire extinguishing, rescue and escape equipment outside the building
