Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts installation and lifting, in particular to a novel balancing crane. Background Art

[0002] When lifting a heavy, flat, cylindrical workpiece on a lathe, the adjustable strong magnetic base used has a suction area that affects the suction reliability. It can only suck the large flat surface of the workpiece and then lift it onto the lathe and place it flat. Then, the workpiece must be manually raised 90 degrees and placed on the lathe chuck. One hand holds it firmly while the other hand clamps it. Since the workpiece is heavy and there are few clamping areas, it is very easy to slip and cause injuries to people and machine tools. This is not only unsafe but also time-consuming and labor-intensive.

[0003] The lifting ring of the adjustable strong magnetic seat in the prior art does not have a large degree of swing and positioning function. When the workpiece is sucked and lifted, the plane of the workpiece can only be placed in an upward or downward state, and the plane cannot be raised 90 degrees. At the same time, the overall posture after suction and lifting has no adjustment and balance stability function. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of balancing crane to address the defects in the existing technology, so that after the strong magnetic seat absorbs the large flat surface of the workpiece, the workpiece plane can be raised at 90 degrees by positioning and counterweight adjustment, making it easier, faster and safer to clamp the outer circle of a large, flat and heavy workpiece on a lathe.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new type of balancing crane, including an adjustable strong magnetic base, a positioning pin group, a balance rod, a counterweight block and an extended lifting ring; the extended lifting ring is rotatably fixed on the adjustable strong magnetic base, and the rotation of the extended lifting ring on the adjustable strong magnetic base is limited by the positioning pin group; the balance rod is arranged on the extended lifting ring, and forms a 90-degree angle with the adjustable strong magnetic base after the extended lifting ring is limited by the positioning pin group; the counterweight block is movably arranged on the balance rod.

[0006] Furthermore, a locking bolt is provided, which is arranged on the counterweight block and limits the movement of the counterweight block on the balance bar.

[0007] Furthermore, a protective flat pad is provided at the fixing point of the balance rod and the extended lifting ring, and an anti-fall-off flat pad is provided at the other end.

[0008] Furthermore, the positioning pin group is further provided with a positioning pin, a positioning spring and a positioning pull rod. The positioning pin group limits and fixes the lengthened lifting ring by pulling the positioning pull rod in conjunction with the positioning pin and the positioning spring.

[0009] Furthermore, the balance bar is also provided with a hook hanging bend.

[0010] Furthermore, the positioning pin group is rotatably fixed on the adjustable strong magnetic base through positioning pins and hexagon socket bolts.

[0011] Furthermore, the adjustable strong magnetic base is also provided with an adjustable strong magnetic base suction surface.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] A new type of balance crane, such as Figure 1 、 2 As shown, it includes an adjustable strong magnetic base 1, a positioning pin group 2, a balance rod 3, a counterweight 4 and an extended lifting ring 6; the extended lifting ring 6 is rotatably fixed on the adjustable strong magnetic base 1, and the rotation of the extended lifting ring 6 on the adjustable strong magnetic base 1 is limited by the positioning pin group 2; the balance rod 3 is arranged on the extended lifting ring 6, and forms a 90-degree angle with the adjustable strong magnetic base 1 after the extended lifting ring 6 is limited by the positioning pin group 2; the counterweight 4 is movably arranged on the balance rod 3.

[0021] Specifically, by providing a rotatable extended lifting ring 6 and an adjustable strong magnetic base 1, the balance crane can flexibly meet the lifting requirements of workpieces of different shapes and weights. The design of the positioning pin group 2 enables the extended lifting ring 6 to be precisely positioned at a specific angle, thereby ensuring the stability and accuracy of the workpiece during the lifting process, avoiding shaking and deviation of the workpiece during the lifting process, and improving work efficiency and safety. The combined use of the balance bar and counterweight block provides additional stability and balance for the lifting process. By adjusting the position and weight of the counterweight block, the dynamic balance during the lifting process can be further optimized, reducing the difficulty and labor intensity of the operation.

[0022] As a preferred embodiment of the above, Figure 1 As shown, a locking bolt 5 is further provided. The locking bolt 5 is provided on the counterweight 4 and limits the movement of the counterweight 4 on the balance bar 3 .

[0023] Specifically, the provision of locking bolts 5 allows the operator to securely fasten counterweight 4 to balance bar 3 after adjusting it to the appropriate position. This securing mechanism ensures that counterweight 4 will not move due to vibration or external forces during the lifting process, thereby maintaining the stability of the entire lifting system and improving operational safety. When lifting heavy objects, any slight sway or deviation can have serious consequences. The design of locking bolts 5 helps prevent this from happening, thereby protecting the safety of the operator.

[0024] As a preferred embodiment of the above, Figure 1As shown, a protective flat pad 6-1 is provided at the fixing point of the balance bar 3 and the extended lifting ring 6, and an anti-fall-off flat pad 6-2 is provided at the other end.

[0025] Specifically, the provision of protective flat pads 6-1 and anti-slip flat pads 6-2 effectively enhances the stability of the connection between balancing rod 3 and extended lifting ring 6 by increasing the contact area and providing additional support. This helps prevent the connection from loosening or falling due to vibration or external forces during the lifting process, further improving the safety of the entire lifting system. They can prevent potential hazards such as workpieces falling due to loose or falling connections, thereby protecting the lives of operators.

[0026] As a preferred embodiment of the above, Figure 2 As shown, the positioning pin group 2 is also provided with a positioning pin 2-1, a positioning spring 2-2 and a positioning pull rod 2-3. The positioning pin group 2 limits and fixes the extended lifting ring 6 by pulling the positioning pull rod 2-3 to cooperate with the positioning pin 2-1 and the positioning spring 2-2.

[0027] Specifically, the precise fit between positioning pin 2-1 and extended lifting ring 6 ensures the stable positioning of the lifting ring at a specific angle. Positioning spring 2-2 provides the necessary elastic force, allowing positioning pin 2-1 to securely engage the lifting ring's positioning hole, preventing it from loosening or falling out due to vibration or external forces. The positioning rod 2-3 is designed so that the operator can easily pull the rod, thereby driving the positioning pin 2-1 to move. This design not only simplifies the operation process but also improves adjustment efficiency, allowing the operator to quickly position the lifting ring at the desired angle as needed without complex adjustments or corrections.

[0028] As a preferred embodiment of the above, Figure 1 As shown, the balance bar 3 is also provided with a hook hanging bend 3-1.

[0029] Specifically, the hook's 3-1 hook-holding bend design allows the hook to be hung on the balance bar more conveniently and securely. This design not only simplifies the hoisting preparation process, but also improves the efficiency and safety of the hoisting.

[0030] As a preferred embodiment of the above, Figure 1 As shown, the positioning pin group 2 is rotatably fixed on the adjustable strong magnetic base 1 through the positioning pin 2-1 and the hexagon socket bolt.

[0031] As a preferred embodiment of the above, Figure 1 As shown, the adjustable strong magnetic base 1 is also provided with an adjustable strong magnetic base suction surface 1-1.

[0032] Specifically, in order to ensure safety and effectiveness, it is necessary to use an adjustable strong magnetic base 1 with a suction force in kilograms that is at least twice the weight of the workpiece to be sucked, and improve it with reference to the principle of the old scale. First, slide the counterweight 4 to one end of the balance bar 3 connecting the lifting ring, and tighten the locking bolt 5 to fix it, then pull out the positioning pin 2-1 to make the extended lifting ring 6 stand up and be able to swing freely left and right, and directly align the suction surface 1-1 of the adjustable strong magnetic base with the approximate center of the workpiece plane, and turn the upper magnetic handle from the OFF position to the ON position to absorb the workpiece, and then rotate the extended lifting ring 6 with the spring-loaded 90-degree positioning pin group 2 toward the adjustable strong magnetic base 1 with the positioning hole. Position it at 90 degrees, then raise the hook and observe the required upright angle, loosen the locking bolt 5 of the counterweight 4, slide the counterweight 4 toward the other end of the balance bar 3 until the plane of the sucked workpiece is upright at 90 degrees, and tighten the locking bolt 5 to keep the workpiece upright at 90 degrees. It can also be adjusted to more than 90 degrees or less than 90 degrees as needed. After the hook is raised and translated to find the position with the lathe, you only need to push the suspended workpiece into the chuck claw of the lathe with one hand and lock it with the other hand, which avoids the risk of moving it by hand or dropping the heavy workpiece while holding it, and reduces labor intensity. In this way, a safer and lighter lifting of a relatively large outer cylindrical flat workpiece on the lathe is completed.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
