Problems solved by technology
[0002] A crane is a mechanical device for lifting heavy objects. Ordinary cranes mainly include brackets, motors and slings; when lifting heavy objects, the sling is pulled by the motor. When the sling is pulled by the motor, the weight of the heavy object is directly controlled by the motor. Therefore, the requirements for the rated parameters of the motor are relatively high. When the motor is damaged, it cannot be replaced by a motor of other specifications, that is, the interchangeability of the motor is poor, and the rigid force directly acting on the motor is easy to damage the motor.

Embodiment Construction
[0011] Below in conjunction with accompanying drawing and embodiment the present invention is further described:
[0012] exist figure 1 In the shown embodiment one, the Pascal crane includes a support 1, a water container 2 is arranged above the support 1, a water outlet valve (not shown) is provided on the water container 2, and a buoyancy force is provided in the water container 2. chamber 3, the buoyancy chamber 3 leads the sling 4 through the reversing pulley block 5, and the setting of the reversing pulley block 5 satisfies the following relationship: the rise of the buoyancy chamber 3 drives the sling 4 outside the water container 2 Part of the rise, the support 1 is provided with a water pump 6 that can deliver water to the water container 2 .
[0013] In the Pascal crane mentioned above, the water outlet valve on the water container 2 is a solenoid valve, and its opening and closing action is controlled by an electric control device.
[0014] In the above-mentioned ...

The invention provides a Pascal crane comprising a bracket; a water container is arranged at the upper part of the bracket; a water outlet valve is arranged on the water container; and a buoyancy cavity is arranged in the water container, the buoyancy cavity can lead out a sling by a reversing pulley block which meets the following relationships: the rising of the buoyancy cavity can drive the rising of the sling at the outer side part the water container, and the bracket is provided with a water pump that can convey water into the water container. The Pascal crane can convert buoyancy into lifting power on a heavy object, thus avoiding the direct action of a heavy object on a motor, so that the interchangeability of the motor is greatly enhanced, and the motor is not easy to damage; in addition, the Pascal crane can store extra energy so as to be used for extra power when lifting the heavy object.
Description
Technical field [0001] The invention relates to a mechanical device, in particular a mechanical crane, comprising a bracket and a sling. Background technique [0002] A crane is a mechanical device for lifting heavy objects. Ordinary cranes mainly include brackets, motors and slings; when lifting heavy objects, the sling is pulled by the motor. When the sling is pulled by the motor, the weight of the heavy object is directly controlled by the motor. Therefore, the requirements for the rated parameters of the motor are relatively high. When the motor is damaged, it cannot be replaced by a motor of other specifications, that is, the interchangeability of the motor is poor, and the rigid force directly acting on the motor is easy to damage the motor. . Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a Pascal crane, which can convert the buoyancy into the lifting force of the heavy object, thereby avoiding th...
