Description

Technical Field

[0001] This utility model relates to the field of pump body lifting equipment technology, specifically a pump body lifting equipment that allows for quick assembly and disassembly. Background Technology

[0002] The pump body consists of two main parts: the suction chamber and the discharge chamber. The suction chamber is generally a short, tapered pipe that gradually narrows or a straight pipe of equal diameter. The discharge chamber resembles a snail shell and is commonly known as a volute. The impeller is enclosed within the volute. An exhaust port (filling port) is located at the top of the pump body for vacuuming or filling. In existing technology, the pump body is manufactured as follows: the main body is first cast from materials such as cast iron or cast steel into a pump body blank. After demolding and cooling, the blank is moved to a machining center where it undergoes drilling, grinding, and other processes to form a smooth-surfaced shell.

[0003] In this process, the conventional method is to connect the pump body with a lifting chain, and then use a cantilever crane in the factory to lift the pump body to the machining center for positioning. After the pump body is processed in the vertical machining center, the above steps are repeated to move the pump body out of the machining center. During the operation, connecting the lifting chain to the pump body is cumbersome and time-consuming, and it is difficult to determine the center of gravity of the pump body when connecting. If the center of gravity is not centered, the pump body will tilt during lifting and moving, which will create a safety hazard. Utility Model Content

[0025] Example 1

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] A pump body lifting tool with quick assembly and disassembly has a reasonable structural design, which can quickly fix and lift the pump body, and effectively balance the pump's center of gravity to avoid tilting during lifting, thereby improving operational safety and efficiency.

[0028] The lifting device includes a fixed frame 5, which is set on an external lifting device frame and serves as the load-bearing base for lifting. The fixed frame 5 is connected to a fixing mechanism 2 via a connecting mechanism 3. The pump body 1 is placed inside the fixing mechanism 2 for fixing the pump body 1. A balancing mechanism 4 is also provided between the fixed frame 5 and the connecting mechanism 3 to balance the center of gravity of the pump body 1 during hoisting. The fixed mechanism 2 includes a support plate 6 located under the bottom surface of the pump body 1. The support plate 6 is a steel plate, and clamping blocks 9 are symmetrically inserted and slidably installed inside it. The inner side of the clamping blocks 9 is an arc shape adapted to the outer wall of the pump body 1. The same movable plate 8 is welded to the bottom surface. An adjusting screw 7 is inserted and rotatably installed in the middle of the movable plate 8. The support plate 6 is inserted into the top of the adjusting screw 7 and screwed on. By rotating the adjusting screw 7, the movable plate 8 and the clamping blocks 9 can be moved up and down. The connecting mechanism 3 includes a first connecting rope 10 symmetrically arranged on both sides of the support plate 6. The first connecting rope 10 is a high-strength steel wire rope. One end is connected to a connecting plate 11, which is a steel plate. A second connecting rope 14 is symmetrically connected to the top of the connecting plate 11. The second connecting rope 14 is also a high-strength steel wire rope and is connected to the fixed frame 5.

[0029] The balancing mechanism 4 includes a support frame 19 symmetrically arranged within the fixed frame 5. A rope drive mechanism 18 is installed on the support frame 19. The rope drive mechanism 18 is an electric winch. A third connecting rope 15 is connected to the output end of the support frame 19. The third connecting rope 15 is inserted into the fixed frame 5 and slidably assembled. The other end is connected to a balancing plate 12. The balancing plate 12 is inserted into a connecting plate 11 and slidably assembled. An avoidance hole 13 is provided on the outer wall of the balancing plate 12. The first connecting rope 10 is inserted into the avoidance hole 13 to avoid mutual interference with the balancing plate 12. A fixed frame 16 is welded to one side of the fixed frame 5. A guide wheel 17 is installed on the fixed frame 16. The guide wheel 17 abuts against the third connecting rope 15 and guides the third connecting rope 15. The rope drive mechanisms 18 are arranged facing each other.

[0030] In use, first place the pump body 1 on the support plate 6, and rotate the adjusting screw 7. Since the adjusting screw 7 is screwed to the support plate 6, and the movable plate 8 is rotatably connected to the adjusting screw 7, the rotation of the adjusting screw 7 drives the movable plate 8 to move upward. The movable plate 8 drives the clamping block 9 to slide upward within the support plate 6, and the clamping block 9 gradually approaches the outer wall of the pump body 1 until the pump body 1 is clamped and fixed. Then, the fixed frame 5 is lifted by the external lifting frame. At this time, the first connecting rope 10 and the second connecting rope 14 of the connecting mechanism 3 lift the pump body 1 for hoisting and transportation. During the hoisting process, if the pump body 1 tilts, observe the tilt direction of the pump body 1 and activate the rope drive mechanism 18 on the corresponding side. For example, when the pump body 1 tilts to the left, activate the rope drive mechanism 18 on the left side. 8. The rope drive mechanism 18 winds up the third connecting rope 15. Under the guidance of the guide wheel 17, the third connecting rope 15 pulls the balance plate 12 upward. The balance plate 12 slides upward in the connecting plate 11, and its bottom surface contacts the left side of the connecting plate 11, applying a supporting force to the first connecting rope 10 on the left side, relieving the stress on the first connecting rope 10 on the left side, adjusting the center of gravity of the pump body 1, so that the pump body 1 is gradually balanced, and continuing to lift the pump body 1 to the machining center for positioning. After reaching the designated position, the adjusting screw 7 is rotated in the opposite direction, and the movable plate 8 drives the clamping block 9 to move downward, releasing the clamping of the pump body 1, and placing the pump body 1 in the machining center. After the pump body 1 is processed, the pump body 1 is lifted out of the machining center again by the lifting device according to the above steps to complete the lifting operation.

[0031] The fixing mechanism 2 drives the movable plate 8 and clamping block 9 to move by adjusting the screw 7. The clamping block 9 clamps and fixes the pump body 1, realizing the quick fixing and disassembly of the pump body 1. The operation is simple and efficient. The connecting mechanism 3 connects the fixing mechanism 2 to the fixing frame 5 through the first connecting rope 10, the connecting plate 11 and the second connecting rope 14. When the fixing frame 5 is lifted, the tension of the connecting rope realizes the hoisting and transportation of the pump body 1. The rope drive mechanism 18 of the balancing mechanism 4 drives the third connecting rope 15 to pull the balancing plate 12. The balancing plate 12 applies a supporting force to the corresponding side of the connecting plate 11, adjusts the force state on both sides of the connecting mechanism 3, and thus adjusts the center of gravity position of the pump body 1, so that the pump body 1 remains balanced during hoisting and avoids tilting.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
