Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a submersible sewage pump hoisting device. Background Art

[0002] Submersible sewage pump is a submersible sewage pump that can tear and cut long fibers, bags, belts, grass, cloth strips and other materials in sewage, and then discharge them smoothly. It is particularly suitable for conveying liquids containing hard solids and fibers, as well as particularly dirty, sticky and slippery liquids. Especially in the treatment of sludge accumulated at the bottom of the sewage treatment pool, the submersible sewage pump is an indispensable component.

[0003] However, the application of submersible sewage pumps in existing sewage treatment systems still has the following shortcomings: the lifting device of the submersible sewage pump is relatively fixed and can only handle the sludge at a certain point in the sewage pool. If the sludge at the bottom of the entire sewage pool is to be cleaned up, multiple groups of submersible sewage pumps are required to be deployed for processing, or the lifting device needs to be moved to the side of the pool, which is costly and cumbersome to use.

[0004] Patent No. CN215974719U discloses a large-scale walking submersible sewage pump lifting device, which can realize the lifting, swinging and linear motion of the submersible sewage pump, and then the position of the submersible sewage pump in the sewage pool can be adjusted arbitrarily, and fixed-point cleaning can be realized; during operation, the operator manually toggles the rocker to make the support column rotate around the bearing seat, and then realizes the manual control of the arc swing movement trend of the submersible sewage pump, but there are the following problems: since the rotation of the support column is realized manually, but the support column lacks a self-locking device, when the submersible sewage pump is suspended in the air and swings in an arc, a deflection force will be generated to make the support column have a tendency to rotate. If the swing amplitude of the submersible sewage pump is too large and the deflection force generated is too large, it is difficult to ensure the stability of the support column by relying solely on the human hand to support the rocker, so that the support column rotates with the swing of the submersible sewage pump, which will not only cause the inaccurate position of the submersible sewage pump, but also further aggravate the swing of the submersible sewage pump, which is not conducive to the rapid stabilization and subsequent installation of the submersible sewage pump, and reduces the installation or lifting efficiency of the submersible sewage pump.

When in use, expansion bolts, steel columns, etc. can be inserted into the mounting holes to fix the mounting rail on the bottom surface of the pool edge to ensure the overall stability of the device.

[0010] Furthermore, a T-shaped slide groove is provided in the middle of the support column, an adapted slider is slidably connected in the T-shaped slide groove, and the fixed end of the telescopic rod is fixedly connected to the slider.

[0023] The working principle of this utility model:

[0024] When hoisting the submersible sewage pump, first start the first drive motor 3, the first drive motor 3 drives the first screw 4 to rotate, so that the mounting seat 2 moves in the mounting guide rail 1 and moves to the preset mounting point, then connect the hook on the electric hoist 10 to the required submersible sewage pump, and then realize the vertical movement of the submersible sewage pump through the electric hoist 10, and at the same time, the electric hoist 10 moves on the crossbeam 6 to control the distance between the submersible sewage pump and the pool edge. The electric hoist 10 adopts the MD model and uses wireless control to facilitate remote control by the operator; on the other hand, the rotation of the support column 5 is controlled by controlling the reduction motor 8 so that the hoisted submersible sewage pump can be moved to any point, and after the rotation of the support column 5 is completed, the reduction motor 8 can self-lock to prevent the support column 5 from further rotating due to the swing of the submersible sewage pump, thereby ensuring the accuracy of the position of the submersible sewage pump. At the same time, when the submersible sewage pump is hoisted out of the water from the sewage, the clamping assembly clamps the submersible sewage pump, which can effectively prevent the submersible sewage pump from shaking and ensure the stability of the submersible sewage pump during movement.

[0025] Specifically, in this embodiment, the clamping assembly includes a second drive motor 11, a second screw rod 12, a telescopic rod 13 and a manipulator 14.

[0026] The telescopic rod 13 preferably uses an existing hydraulic telescopic rod, and the manipulator 14 uses a hydraulic manipulator in the prior art. The telescopic rod 13 is in a retracted state before use. When the submersible sewage pump is hoisted and located above the water surface, the second drive motor 11 is started to rotate the second screw rod 12 and drive the telescopic rod 13 to move up and down, so that the telescopic rod 13 moves to the same height as the submersible sewage pump, and then the telescopic rod 14 extends the manipulator 14 forward to grab the submersible sewage pump to prevent the submersible sewage pump from shaking. At this time, the support column 5 can be rotated or the mounting base 2 can be moved or the electric hoist 10 can be adjusted to adjust the position of the submersible sewage pump.

[0027] Specifically, in this embodiment, the mounting rail 1 is provided with a plurality of evenly arranged mounting holes 16 on both sides along its length direction.
