[0002] With the rapid development of modern industrial technology, cranes, as an important material handling equipment, play a vital role in engineering construction, logistics transportation, production and manufacturing and other fields. Traditional cranes usually adopt a simple boom structure and achieve material handling by adjusting the angle and length of the boom. However, this structure is often difficult to achieve balance adjustment when dealing with materials of different weights, which makes the crane prone to shaking, tilting and other phenomena during operation. When the weight of the items is large, the crane is very likely to become unstable or even collapse, posing a serious threat to the safety of personnel and property, and seriously affecting the safety and efficiency of the operation. Therefore, it is necessary to design a crane with a balance adjustment structure. Utility Model Content

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a crane with a balance adjustment structure proposed by the utility model comprises a balance mechanism 1, a column 3 and a lifting mechanism 6. A base 5 is fixedly installed at the bottom of the column 3 by bolts. A supporting foot is fixedly connected to the bottom of the base 5. By placing it in a suitable position, the base 5 can be used to support the mechanism at the top to avoid tipping over during lifting. A rotating beam 2 is rotatably installed at the top of the column 3. The rotating beam 2 and the column 3 are rotatably installed by a rotating shaft, so that the rotating beam 2 can be rotated to facilitate the adjustment of the lifting position. A limiting frame 8 is fixedly installed at the top of the rotating beam 2 by bolts. A lifting beam 7 is slidably installed on the inner side of the limiting frame 8. A slider 802 is fixedly installed on the inner wall of the limiting frame 8. A slide groove 701 is provided at the front and rear ends of the lifting beam 7. The slide groove 701 is cooperatively connected with the slider 802, so that the slide groove 701 can slide up and down along the slider 802, so that the lifting beam 7 can move up and down on the inner side of the limiting frame 8.
[0022] A lifting mechanism 6 is provided on one side of the lifting beam 7. The lifting mechanism 6 includes an electric winch 601, a steel cable 602 and a hook 603. The electric winch 601 is connected to one side of the lifting beam 7. The electric winch 601 is composed of an axle frame, a capstan and a driving motor. The axle frame is fixed on one side of the lifting beam 7 and can support the capstan. The capstan can be driven to rotate by the driving motor. A steel cable 602 is wound around the outer side of the electric winch 601. The capstan in the electric winch 601 can be used to rotate and the steel cable 602 can be retracted and released. A hook 603 is fixedly installed at the bottom of the steel cable 602. The hook 603 can be conveniently connected to an object for hanging. The steel cable 602 can be retracted and released by the electric winch 601, so that the object can be lifted and placed conveniently.
[0023] A balancing mechanism 1 is provided on the other side of the lifting beam 7. The balancing mechanism 1 includes a fixed frame 101, a counterweight box 102, a track groove 103, a track wheel 104 and a movable rod 105. The fixed frame 101 is fixedly installed between the lifting beam 7, and the counterweight box 102 is slidably connected to the inner side of the fixed frame 101. The front end and the rear end of the fixed frame 101 are provided with a track groove 103. The counterweight box 102 and the track groove 103 are slidably installed through the track wheel 104, so that the track wheel 104 can roll in the track groove 103, and the counterweight box 102 can be moved left and right. The counterweight box 102 can be conveniently placed for counterweighting. The movable rod 105 is movably connected between the counterweight box 102 and the rotating beam 2. When the object is lifted by the lifting mechanism 6, when the weight of the object is large, the lifting beam 7 can be pressed to move downward, and the fixed frame 101 can be driven downward synchronously, so that the counterweight box 102 The movable rod 105 is squeezed to make the movable rod 105 flip downward. When the movable rod 105 flips, one end of the movable rod 105 can be extended to the right, which can push the counterweight box 102 to move to the right. Through the movement of the counterweight box 102, the center of gravity can be brought closer to the middle position, so that the weight at both ends of the lifting beam 7 can achieve a balanced effect, which can effectively avoid shaking, tilting and other phenomena, and can reduce the situation of collapse accidents caused by instability, thereby improving the safety effect. A thrust spring 801 is fixedly connected between the lifting beam 7 and the limit frame 8. The thrust spring 801 is located on the inner side of the limit frame 8. After the object to be lifted is placed, the thrust of the thrust spring 801 can be used to push the lifting beam 7 to move upward, and the movable rod 105 can be used to pull the counterweight box 102 to move to the left for reset, so that the counterweight box 102 can be moved for balance adjustment operation when lifting the object next time.
[0024] A supporting mechanism 4 is fixedly installed at the bottom of the rotating beam 2, and the supporting mechanism 4 includes a collar 401, a supporting frame 402, an operating handrail 403 and a roller 404. The collar 401 is sleeved on the outer side of the column 3, and the collar 401 and the column 3 are rollingly supported by the roller 404. The collar 401 can be rotated on the surface of the column 3 by rotating the roller 404. The supporting frame 402 and the rotating beam 2 are fixedly installed by bolts, and the supporting frame 402 and the collar 401 are fixedly connected. The bottom of the rotating beam 2 can be supported by the supporting frame 402, so as to improve the structural strength of the rotating beam 2 and make it less likely for the rotating beam 2 to bend. The front and rear ends of the supporting frame 402 are fixedly connected with the operating handrail 403. The rotating beam 2 can be pushed to rotate by using the operating handrail 403. After the object can be lifted, the position of the object can be changed by pushing the rotation of the rotating beam 2, so as to facilitate the transportation operation of the object.
[0025] The working principle of the crane with a balance adjustment structure based on the embodiment is as follows: the base 5 is placed in a suitable position for use, the counterweight block is placed in the counterweight box 102 for counterweighting, the object to be lifted is hung and connected by the hook 603, and the steel cable 602 can be driven to be reeled in by the electric winch 601, so that the object can be lifted conveniently, and the lifting beam 7 can be pressed by the weight of the object to move downward along the limit frame 8, so that the counterweight box 102 can squeeze the movable rod 105, and the movable rod 105 will flip downward due to the squeezing, so that one end of the movable rod 105 extends to the right, which can push the counterweight box 102 to move to the right, and the track wheel 104 can be used to move in the track groove 103. The counterweight box 102 can be easily pushed. When the counterweight box 102 moves to the right, the weight can be moved to the middle position, which can automatically balance the weight at both ends of the lifting beam 7 to avoid the collapse caused by tilting and instability. The support frame 402 can support the rotating beam 2 to improve the structural strength of the rotating beam 2. The operating armrest 403 can be used to push the rotating beam 2 to rotate, which can facilitate the rotation and movement of objects and the transportation of objects. After the object is transported and placed, the thrust spring 801 can be used to push the lifting beam 7 to move upward, and the movable rod 105 can be used to pull the counterweight box 102 to reset, which is convenient for automatic balancing operation when lifting the object next time.
