[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0028] like Figure 1-3 As shown, a tooling for hoisting and transporting a pump bearing housing includes a movable shaft 1, a pump bearing housing 2, a transport structure, and a support structure. Movable wheels 3 are provided on both the front and back of the movable shaft 1.
[0029] The handling structure includes a fixed frame 4, a lever shaft 5, a limiting block 6, a lifting strap 7, and a handle structure. There are two fixed frames 4, which are symmetrically distributed on the front and back of the outer surface of the movable shaft 1. The lever shaft 5 is located on the top of the two fixed frames 4 on opposite sides. There are two limiting blocks 6, which are both located on the left side of the top of the lever shaft 5. The lifting strap 7 is located on the outer surface of the lever shaft 5. The length of the lever shaft 5 on the left side of the fixed frame 4 is less than the length of the lever shaft 5 on the right side of the fixed frame 4.
[0030] Specifically, a first fixed shaft is provided at the top between opposite sides of the fixed frame 4, extending through and to the outside of the lever shaft 5. The lever shaft 5 is movably connected to the fixed frame 4 through the first fixed shaft. A first rotating hole adapted to the size of the first fixed shaft is opened inside the lever shaft 5, so that the lever shaft 5 can rotate stably around the fixed shaft.
[0031] In this embodiment, the lever principle can be used to easily hoist and move the pump bearing housing 2 and place it in the designated position, which greatly reduces the labor intensity of employees and improves work efficiency.
[0032] like Figure 1 and 3 As shown, fixing holes are provided on the front and back sides of the bottom of the outer surface of the sling 7. The pump bearing housing 2 is hung on the sling 7 through the fixing holes. The sling 7 is located between two limiting blocks 6. The top of the two limiting blocks 6 is provided with a groove. A stop bar 8 extending into the other groove is provided inside one of the grooves.
[0033] In this embodiment, the stop bar 8 is designed to prevent the sling 7 from accidentally coming off between the limit blocks 6.
[0034] like Figure 1 and 3 As shown, the grip structure is located on the right side of the lever shaft 5. The grip structure includes a connecting block 9 and a grip 10. The connecting block 9 is located on the right side of the lever shaft 5, and there are two grips 10, which are symmetrically distributed on the front and back of the connecting block 9.
[0035] Specifically, the outer surface of the grip 10 is provided with an anti-slip sleeve, which enhances the anti-slip performance and makes it less likely for the grip 10 to slip.
[0036] In this embodiment, the two grips 10 allow the operator to operate with both hands separately, making it easier to exert force.
[0037] like Figure 1-2As shown, the support structure includes a movable block 11, a fixed rod 12, and a movable rod 13. The movable block 11 is located in the middle of the outer surface of the lever shaft 5. The fixed rod 12 is located at the bottom of the movable block 11, and the movable rod 13 is located at the bottom of the fixed rod 12. The fixed rod 12 has a movable spring that is fixedly connected to the movable rod 13 inside. The bottom of the movable rod 13 has an anti-slip block.
[0038] Specifically, a second fixed shaft is provided in the middle of the inner side of the movable block 11, which passes through and extends to the outside of the lever shaft 5. The movable block 11 is movably connected to the lever shaft 5 through the second fixed shaft. The inside of the lever shaft 5 is provided with a second rotating hole that matches the size of the second fixed shaft. The bottom of the inner side of the movable block 11 does not contact the bottom of the outer surface of the lever shaft 5, so that the movable block 11 can rotate at a small angle relative to the lever shaft 5, thus avoiding the situation where the movable rod 13 is misaligned and not perpendicular to the ground when the right side of the lever shaft 5 is pressed down.
[0039] In addition, the maximum extendable length of the movable rod 13 is higher than the horizontal line of the bottom of the outer surface of the movable wheel 3 to prevent and avoid affecting the normal movement of the whole. When normal movement is required, the lever shaft 5 is kept horizontally parallel or slightly tilted to the left to ensure that the anti-slip block does not contact the ground.
[0040] In this embodiment, the support structure enhances the stability of the overall structure, preventing displacement or swaying during hoisting.
[0041] The method of using this utility model is as follows:
[0042] When in use, lower the left side of the lever shaft 5 and raise the right side. Hang the pump bearing housing 2 on the sling 7 through the fixing hole on the sling 7. Then press down on the two handles 10 to start the hoisting. During the hoisting process, the anti-slip block will contact the ground and be more firmly fixed under the action of the spring, avoiding any deviation or shaking. When it is necessary to move, make the lever shaft 5 horizontal and parallel or slightly tilted to the left to ensure that the anti-slip block does not contact the ground.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
