This not only increases the difficulty of the operation, but also may affect the efficiency and safety of the entire lifting operation. To this end, we propose a multi-condition heavy equipment lifting tool. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Example 1

[0026] The top of the fixed frame 1 is welded and fixed with an arc frame 3 in a bilaterally symmetrical manner. The arc frame 3 is used for winding the wire rope. Figure 7 As shown in FIG, by providing the arc frame 3, the fixing frame 1 can be used for hoisting operations on large generator stators.

[0027] A storage slot 4 is provided in the middle of the fixed frame 1, and a lifting frame 5 which can be adjusted in height along the storage slot 4 is installed in the storage slot 4. A lifting slot 6 is provided on the side wall of the fixed frame 1, and the lifting slots 6 are symmetrically distributed on the left and right with the storage slot 4 as the center. Lifting mechanisms 7 are fixedly installed in the lifting slots 6 on both sides, respectively, and the lifting mechanisms 7 are transmission-connected with the lifting frames 5. By controlling the lifting mechanisms 7 provided on both sides to perform synchronous actions, the lifting operation of the lifting frame 5 in the lifting slot 6 can be completed. A hook 9 is installed in the lifting frame 5, and the lifting frame 5 and the hook 9 are detachably fixedly assembled through a connecting component 8, such as Figure 1 and Figure 5 As shown in the figure, the hook 9 is in a straight line or a cross shape. During the lifting of heavy equipment, the corresponding hook 9 can be selected to be connected and fixed to the lifting frame 5 according to the specific requirements of the lifting.

[0028] like Figure 2 As shown in , the lifting mechanism 7 includes a lifting screw 71, which is rotatably connected to the lifting slot 6. The lifting screw 71 passes through the lifting block 51 and is screwed to the lifting block 51 through threads. The lifting block 51 is integrally formed in the lifting frame 5. A driving motor 72 is fixedly assembled on the top of the fixed frame 1. The output end of the driving motor 72 is fixedly connected to the top of the lifting screw 71 through a coupling. The thread directions of the lifting screws 71 in the lifting slots 6 on both sides are the same, and the driving motors 72 on both sides are electrically connected to an external power supply and an external controller. The output ends of the driving motors 72 on both sides are controlled by the external controller to drive the synchronous rotation of the lifting screws 71, so that the lifting block 51 can drive the lifting frame 5 to perform lifting actions in the lifting slot 6. The two sets of lifting mechanisms 7 are provided to improve the stability of the height position adjustment process of the lifting frame 5.

[0029] like Figure 4 As shown in the figure, the connecting assembly 8 includes a connecting groove 81, which is opened in the middle of the lifting frame 5. The top of the hook 9 is fixedly connected with a connecting block 82 whose size is adapted to the connecting groove 81. The side wall of the lifting frame 5 is inserted with a fixed shaft 83 that penetrates into the connecting block 82. A fixing bolt 84 is fixedly assembled between the fixing shaft 83 and the lifting frame 5. The connecting block 82 is inserted into the connecting groove 81, and then the fixing shaft 83 penetrates the connecting block 82. The fixing bolt 84 connects and fixes the fixing shaft 83 to the lifting frame 5, thereby realizing a detachable connection and fixation between the hook 9 and the lifting frame 5.

[0030] like Figure 1As shown in the figure, the top of the fixing frame 1 is symmetrically welded with auxiliary fixing rings 10 on the left and right. The auxiliary fixing rings 10 can be used to bundle auxiliary steel wire ropes between heavy equipment to prevent the heavy equipment from falling off during the lifting process, thereby further protecting the heavy equipment.

[0031] Working principle: Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown in the figure, during the use of the utility model, according to the lifting requirements of the heavy equipment to be lifted, the fixed frame 1 or the hook 9 can be selected to lift the equipment, such as Figure 1 and Figure 6 As shown in the figure, when the hook 9 is needed to lift the heavy equipment, the lifting frame 5 is adjusted to the lower position of the lifting slot 6 through the synchronous action of the lifting mechanisms 7 on both sides, so that the hook 9 is extended out of the storage slot 4, and the corresponding hook 9 is selected according to the type of equipment to be lifted, and the hook 9 is connected and fixed to the lifting frame 5, and then the heavy equipment can be lifted by the hook 9 in combination with the wire rope, as shown in the figure. Figure 5 and Figure 7 As shown in the figure, when the hook 9 is not needed to lift the heavy equipment, the lifting frame 5 is driven to rise by the lifting mechanism 7, so that the hook 9 is moved to the storage groove 4 for storage, and then the heavy equipment is lifted by the arc frame 3 in combination with the wire rope. At this time, the hook 9 will not affect the lifting of the heavy equipment, and the lifting needs of more working conditions are met.

[0032] Example 2

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution which is different from the technical solution in the first embodiment in that: auxiliary fixing mechanisms 11 are respectively installed between the lifting blocks 51 in the lifting slots 6 on both sides and the corresponding lifting slots 6, and an opening slot 12 is opened at the top of the lifting slot 6. A driving component 13 that penetrates the opening slot 12 to the lifting slot 6 is fixedly installed on the top of the fixing frame 1. The action of the fixing unit in the auxiliary fixing mechanism 11 is controlled by the driving component 13. The auxiliary fixing mechanism 11 can increase the stability of the fixation between the lifting frame 5 and the lifting slot 6, and avoid that only the lifting screw 71 in the lifting mechanism 7 bears gravity during the lifting process using the hook 9, which easily causes slippage between the lifting block 51 in the lifting frame 5 and the lifting screw 71, affecting the subsequent adjustment of the height position of the lifting frame 5 by the lifting mechanism 7.

[0034] like Figure 2As shown in, the auxiliary fixing mechanism 11 includes a piston cavity 111, which is opened in the lifting block 51. A piston frame 112 that can move left and right is slidably connected in the piston cavity 111. The side wall of the piston frame 112 is evenly fixedly connected with a positioning pin 113 that penetrates the lifting block 51. A sealing ring is provided at the connection between the positioning pin 113 and the lifting block 51 to prevent the hydraulic oil stored in the piston cavity 111 from leaking outward from the connection between the positioning pin 113 and the lifting block 51. The side wall of the lifting groove 6 is evenly opened with a first positioning hole 114 and a second positioning hole 115. The first positioning hole 114 is located below the second positioning hole 115. The lifting frame 5 is fixed in the lifting groove 6 for adjusting the height position. The positioning pin 113 is inserted into the first positioning hole 114 and the second positioning hole 115 at different positions to fix the position of the lifting frame 5, and complete the storage below the hook 9 or in the storage groove 4.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown in , the drive assembly 13 includes an oil tank 131, which is fixedly assembled on the top of the fixing frame 1. The inner cavity of the oil tank 131 and the piston cavity 111 are filled with hydraulic oil. An oil pump 132 is fixedly assembled on the top of the oil tank 131. The oil pump 132 is electrically connected to an external power supply. The input end of the oil pump 132 is plugged into the bottom of the inner cavity of the oil tank 131, and the output end of the oil pump 132 is fixedly connected to two liquid supply connectors 133, as shown in FIG. Figure 3 As shown in the figure, the two liquid supply joints 133 are respectively fixedly equipped with switch valves 134, which are solenoid valves electrically connected to an external power supply and an external controller. The opening and closing of the two liquid supply joints 133 are respectively controlled by setting the switch valves 134, and the front and rear side walls of the oil tank 131 are respectively fixedly connected with recovery joints 135, and the top of the lifting block 51 is respectively provided with liquid supply interfaces 136 and recovery interfaces 137 symmetrically distributed on the left and right. One group of liquid supply interfaces 136 and recovery interfaces 137 are located on the left side of the piston frame 112, and one group of liquid supply interfaces 136 and recovery interfaces 137 are located on the right side of the piston frame 112. Connecting hoses 138 are respectively fixedly connected between the liquid supply interface 136, the liquid supply joint 133, the recovery interface 137 and the recovery joint 135, so as to form a complete hydraulic control pipeline, and the open groove 12 is used for the passage of the connecting hose 138.

[0036] Working principle: Figure 2 , Figure 3 and Figure 4 As shown in FIG. 1 , the stability of the connection and fixation between the lifting frame 5 and the lifting slot 6 is enhanced by setting the auxiliary fixing mechanism 11. The action process of the piston frame 112 and the positioning pin 113 in the auxiliary fixing mechanism 11 is as follows: Figure 2Taking the movement of the inner piston frame 112 as an example, when the piston frame 112 needs to move from left to right in the piston chamber 111, the switch valve 134 of the liquid supply joint 133 connected to the left liquid supply interface 136 is opened, and the oil pump 132 is turned on. After the oil pump 132 is turned on, the hydraulic oil is supplied to the left inner chamber of the piston frame 112 through the corresponding liquid supply joint 133 and the connecting hose 138. The piston frame 112 is pushed to move right in the piston chamber 111 by the hydraulic oil. The hydraulic oil on the right side of the piston frame 112 is recovered into the oil tank 131 through the recovery interface 137, the connecting hose 138 and the recovery joint 135 at the corresponding position. At this time, the positioning pin 113 moves out of the first positioning hole 114 or the second positioning hole 114. Positioning hole 115, the height position of the lifting frame 5 can be adjusted later by the lifting mechanism 7. Conversely, when it is necessary to push the piston frame 112 to move right in the piston chamber 111, the switch valve 134 connected to the liquid supply interface 136 on the right side of the piston frame 112 is opened, and the other switch valve 134 is closed. Then, the hydraulic oil is injected into the piston chamber 111 from the right side of the piston frame 112, pushing the piston frame 112 to move to the left in the piston chamber 111, and the hydraulic oil on the left side of the piston frame 112 is recovered into the oil tank 131 through the corresponding recovery pipeline. At this time, the positioning pin 113 is inserted into the first positioning hole 114 or the second positioning hole 115 to enhance the stability of the fixed position of the lifting frame 5.
