[0002] The main function of lifting equipment is to lift and move heavy objects. They can easily move heavy objects from one location to another by using tools such as wire ropes, chains, hooks, etc., which greatly saves labor costs and improves work efficiency.

[0003] Small hoisting equipment may have difficulty adjusting the counterweight. If the counterweight is difficult to adjust, the hoisting equipment may only be able to adapt to specific hoisting needs and cannot cope with more changes. This will limit the scope of use of the equipment and reduce its flexibility and applicability. Unbalanced or improperly adjusted counterweights may cause the hoisting equipment to become unstable during operation, such as shaking, tilting or losing control. This may not only damage the hoisted objects, but also cause serious injuries to the operator and surrounding personnel, increasing safety risks.

[0004] Therefore, it is necessary to invent a kind of building construction lifting equipment to solve the above problems. Utility Model Content

[0022] A counterweight block 8 is detachably mounted on the top of the mounting plate 9, a gear ring 13 is mounted on the bottom end of the hoisting rod 1 located at the counterweight block 8, a driving gear 17 for driving the gear ring 13 to rotate is arranged on one side of the gear ring 13, a pressure bearing 14 is sleeved on the top end of the gear ring 13 of the hoisting rod 1, a mounting block 7 is fixedly mounted on the top end of the hoisting rod 1 located at the counterweight block 8, one part of the pulley block 5 is mounted on the top end of the mounting block 7, and the gear ring 13 is mounted below the counterweight block 8 to alleviate the situation of gravity center shifting and overturning during the rotation of the hoisted heavy object and improve the stability of the equipment.

[0023] A first rack 2 is provided at the top of the cross arm where the lifting rod 1 is located, and a first gear 4 meshing with the first rack 2 is provided inside the moving component 3. One of the pulley blocks 5 is installed at the bottom of the moving component 3, and a plurality of support rods 6 are provided on both side walls of the lifting rod 1. The pulley blocks 5 are driven by the moving component 3 to slide inward, so that heavy objects can be placed above the load-bearing plate 11 more conveniently, and the counterweight of the lifting equipment can be adjusted by placing heavy objects to meet the needs of lifting different heavy objects.

[0024] The two side walls of the base plate 10 are provided with through grooves, and the two load-bearing plates 11 slide back and forth inside the through grooves where the base plate 10 is located.
