Description

Technical Field

[0001] The utility model belongs to the technical field of lifting tools, and more specifically, particularly relates to a lifting tool. Background Art

[0002] When constructing a distribution room, since many distribution rooms are multi-story structures, electrical equipment needs to be hoisted. When hoisting electrical equipment in existing distribution rooms, a crane is generally used to hoist the electrical equipment. During hoisting, the hoist is connected to the electrical equipment by using a hoist, and then the hook of the crane is connected to the hoist to achieve the hoisting of the electrical equipment. To facilitate the hoisting of electrical equipment, it is generally chosen to be hoisted after the main construction of the distribution room is completed.

[0003] The existing application number is: CN202020664472.8. The utility model discloses a hoisting tool for railway electrical engineering construction, including a hoisting plate, the upper end of which is fixedly connected with a plurality of horizontal mounting frames, and the upper ends of the plurality of mounting frames are connected with the same X-shaped connecting plate, the X-shaped connecting plate and the mounting frame are connected by a plurality of fixing mechanisms, the upper center of the X-shaped connecting plate is fixedly connected with a vertical suspension rod, and the upper end of the suspension rod is fixedly connected with a lifting ring, the lower end of the hoisting plate is fixedly connected with two U-shaped support frames, the horizontal end side walls of the U-shaped support frame are sleeved with a plurality of sliders, and the upper end of the slider is threadedly connected with a fastening knob fixed to the U-shaped support frame, and the lower end of the slider is provided with a positioning mechanism connected with an external device.
