Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a jaw lifting tool with good stability. Background Technique

[0002] A lifting tool refers to a device for lifting heavy objects in a lifting machine. The most commonly used lifting tools for lifting finished items are hooks and slings. Others include eyebolts, lifting suction cups, tongs, jaws, and forklift tines, etc.

[0003] The stability of the lifting tool determines the stability when gripping workpieces. At present, after long-term use, the vertical lifting jaw lifting tool is prone to deformation or wear, resulting in a decrease in stability. Moreover, when the fixed frame and the lifting frame are assembled, there is also a risk that the lifting frame directly disengages from the fixed frame, posing a safety hazard. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Content of the Utility Model

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution: a jaw gripper with good stability, including a fixed frame, a lifting frame, and a U-shaped limit plate 16;

[0020] The fixed frame includes the first corner-end column 1, the first intermediate column 2, the first top long crossbar 3, the first top short crossbar 4, the first bottom long crossbar 5, and the first bottom short crossbar 6. There are four first corner-end columns 1. The tops of the first corner-end columns 1 are respectively connected by the first top long crossbar 3 and the first top short crossbar 4. The bottoms of the first corner-end columns 1 are respectively connected by the first bottom long crossbar 5 and the first bottom short crossbar 6. The middle positions of the first top long crossbar 3 and the middle position of the first bottom long crossbar 5 are respectively connected to the first intermediate column 2. A reinforcing frame 7 is provided between the first corner-end column 1, the first intermediate column 2, and the first bottom long crossbar 5. Sliders 8 are provided on the upper and lower parts inside the reinforcing frame 7. Hanging brackets 17 are provided at the tops of the first corner-end columns 1. Hanging wheels 18 are provided inside the hanging brackets 17. Through the hanging brackets 17 and the hanging wheels 18, the cooperation between the gripper and the hanging rail is realized. A transverse cylinder connection support 19 is provided at the middle position of any one of the first top long crossbars 3. Through the transverse cylinder connection support 19, the connection with the transverse cylinder is realized, thereby realizing the transverse movement of the jaw gripper;

[0021] The lifting frame includes four second corner-end columns 9, second intermediate columns 10, second top long crossbars 11, second top short crossbars 12, second bottom long crossbars 13 and second bottom short crossbars 14. The tops of the second corner-end columns 9 are respectively connected by the second top long crossbars 11 and the second top short crossbars 12, and the bottoms of the second corner-end columns 9 are respectively connected by the second bottom long crossbars 13 and the second bottom short crossbars 14. The middle positions of the second top long crossbars 11 and the second bottom long crossbars 13 are respectively connected to the second intermediate columns 10. Linear guide rails 15 are arranged on the outer surfaces of the second corner-end columns 9 of the lifting frame. The linear guide rails 15 are in sliding fit with the corresponding sliders 8. A U-shaped limit plate 16 is installed on the upper part of the second intermediate column 10. The U-shaped limit plate 16 is in sliding fit with the first intermediate column 2. The inner walls on both sides and the inner wall at the end of the U-shaped limit plate 16 are in sliding contact with the corresponding outer surfaces of the first intermediate column 2 to ensure that the U-shaped limit plate 16 fits exactly with the first intermediate column 2, preventing lateral impact and ensuring the stability of the lifting frame during lifting.

[0022] Assembly method and working principle: First, assemble the fixed frame and the lifting frame separately. Then, install the sliders 8 inside the reinforcing frames 7 of the fixed frame. Two sliders 8 are coaxially installed inside each reinforcing frame 7. Next, install the linear guide rails 15 on the outer surfaces of the second corner-end columns 9 of the lifting frame. After the assembly of the fixed frame and the lifting frame is completed, place the lifting frame into the fixed frame and make the guide rails on the outside of the lifting frame cooperate with the corresponding sliders 8 inside the fixed frame. Finally, put the U-shaped limit plate 16 over the outside of the first intermediate column 2 and connect the two sides of the U-shaped limit plate 16 to the second intermediate column 10 by bolts to complete the assembly. The lifting of the lifting frame is driven by an external vertical cylinder, and the overall lateral movement is pushed by an external lateral cylinder. When the lifting frame is lifted or lowered through the cooperation of the linear guide rails 15 and the sliders 8, the U-shaped limit plate 16 moves up and down along the first intermediate column 2. The structure of the present utility model is reasonable. The lifting frame cooperates with the sliders 8 inside the fixed frame through the linear guide rails 15 on the outside. At the same time, a U-shaped limit plate 16 is installed on the second intermediate column 10. The U-shaped limit plate 16 is in sliding fit with the first intermediate column 2 of the fixed frame, thus ensuring the stability of the lifting frame during the lifting process. At the same time, by setting the U-shaped limit plate 16, it can also be used for limiting to prevent the lifting frame from disengaging from the fixed frame during the assembly or use of the lifting frame and the fixed frame, ensuring safety.

[0023] For the parts not detailed in the present utility model, they are all well-known technologies to those skilled in the art.

[0024] Finally, it should be noted that the above specific implementation manners are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and all of them should be covered by the scope of the claims of the present utility model.
