Description

Technical Field

[0001] This utility model relates to the field of auxiliary mobile machinery for water pumps, and in particular to a water pump unit impeller transfer device for pumping stations and pump rooms. Background Technology

[0002] A pumping station mainly consists of water intake and diversion structures, water intake structures, a pump house, and valve wells. The pump unit refers to a device composed of a water pump, electric motor or diesel engine, control equipment, and piping system. Its main function is to pump water or transport liquids. The impeller of the pump unit requires regular maintenance due to prolonged operation and will be returned to the factory for repair when it malfunctions or is severely worn. The impeller is large and heavy, making disassembly and repair difficult. Currently, the common practice for repairing pump unit impellers is to first move the impeller from the pump base to the pump house passage, then transport it from the passage to directly below the lifting hole, and finally use a crane to lift it out from directly below the lifting hole. This method is limited by space and the weight of the impeller, and large transport equipment such as forklifts cannot be used in this environment. This results in low impeller transport efficiency, and the impeller is prone to rotation when lifted by the crane, making it easy for it to come into contact with the ground and walls, potentially scratching them, and compromising transport safety. Utility Model Content

[0003] The impellers of existing pump units in pumping stations are difficult to disassemble, maintain, and move due to space and weight limitations, resulting in reduced moving efficiency. Furthermore, using existing methods for moving the impellers can lead to them hitting the ground or walls, potentially causing scratches and compromising safety. This application designs a pump unit impeller moving device for pumping stations, with the specific technical solution as follows:

[0004] A pump impeller transfer device for a pump station pump house includes:

[0005] Horizontal plate;

[0006] Three transport tanks are arranged in an isosceles triangle on the lower surface of the horizontal plate.

[0007] Two limiting components are provided, and the two limiting components are positioned close to two of the transport tanks. The line connecting the two transport tanks forms the base of an isosceles triangle.

[0008] The hoisting mechanism is used to hoist the impeller.

[0009] Preferably, the horizontal plate is provided with a connecting block at the position where the transport tank is set, and the connecting block is provided with a mounting groove for holding the disc above the transport tank.

[0010] Preferably, each limiting component includes two limiting pins, which are disposed on one side of the connecting block and are spaced apart, with the distance between them being less than the maximum length of the transport tank.

[0011] Preferably, a circular hole is provided at the center of the horizontal plate, the diameter of which is larger than the diameter of the impeller hub, so that the impeller hub can be inserted into the circular hole.

[0012] Preferably, the horizontal plate is also provided with traction holes. Two traction holes are provided, and the two traction holes are symmetrically arranged with respect to the perpendicular bisector of the isosceles triangle formed by the line connecting the three transport tanks.

[0013] Preferably, the hoisting mechanism includes a fixed pulley, which is located on the roof of the pump house above the impeller of the water pump unit. A steel wire rope is wound on the fixed pulley, with one end of the steel wire rope being a free end and the other end being detachably connected to the impeller.

[0014] The present invention, through the above technical solution, has the following technical effects:

[0015] 1. The transport tank and the horizontal plate work together to form a movable transfer platform, which can be moved directly to the impeller of the water pump unit. With the help of fixed pulleys, the impeller is placed on the horizontal plate, and the transfer is achieved by connecting the external traction mechanism to the horizontal plate. This transfer device has a simple structure and small size, which makes it easy to shuttle in the pump room passage for transfer, and improves the efficiency of impeller disassembly and transfer.

[0016] 2. By setting limiters, the two rear transport tanks are restricted to straight-line transport tanks, while the front transport tank is a turning transport tank. This ensures the direction of the transfer device and prevents the transfer device from damaging the wall. Attached Figure Description

[0021] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0022] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] like Figure 1-3 As shown, a pump impeller transfer device for a pumping station includes a horizontal plate 1, three transport tanks 10, limiting components, and a hoisting mechanism. The horizontal plate 1 is a square stainless steel plate. The three transport tanks 10 are arranged in an isosceles triangle on the lower surface of the horizontal plate 1. During transfer, the transport tank 10 at the apex is positioned at the front, and the two transport tanks at the base are positioned at the rear. The purpose of using transport tanks 10 instead of traditional wheels is to provide higher load-bearing capacity, adapting to the heavy and large impeller conditions. To facilitate control of the entire transfer device and prevent the horizontal plate 1 from colliding with the wall and damaging it during movement, two limiting components are correspondingly installed on one side of the two transport tanks 10 at the base. Each limiting component restricts the rotation of one transport tank 10. Therefore, the two transport tanks 10 at this location will only move in a straight line, and the transfer device's steering is achieved by the transport tank 10 at the apex.

[0024] In addition to the aforementioned components, a hoisting mechanism is also included. The hoisting mechanism is used to hoist the impeller, lifting it out of the pump casing onto the horizontal plate 1. It works in conjunction with the horizontal plate 1 and the transport tank 10 to quickly transfer the water pump impeller.

[0025] It should be noted that the aforementioned transport tank vehicle 10 was purchased directly from the market, and its structure is existing technology; therefore, its structure will not be described in detail here.

[0026] Furthermore, regarding the connection method between the transport tank 10 and the horizontal plate 1, a connecting block 8 is welded to the horizontal plate 1 at the position corresponding to the transport tank 10. The connecting block 8 is a rectangular iron plate, and a circular mounting groove 9 is carved in the center of the connecting block 8. The diameter of the circular mounting groove 9 is slightly larger than the diameter of the disc above the transport tank 10. The disc above the transport tank 10 is inserted into the mounting groove 9 to achieve a detachable connection between the transport tank 10 and the horizontal plate 1. This connection method makes it very convenient to separate the transport tank 10 from the horizontal plate 1, facilitating the maintenance or replacement of the transport tank 10 or the horizontal plate 1.

[0027] Furthermore, the specific structure of each of the above-mentioned limiting components includes two limiting pins 7, which are welded to one side of the connecting block 8, including the inner or outer side. The two limiting pins 7 are spaced apart (here, "front and back" refers to the front and back direction during transport) and the distance between them is less than the maximum length of the transport tank 10. This ensures that when the transport tank 10 rotates, it will be blocked by the limiting pins 7, thus ensuring that the two transport tanks 10 move in a straight line.

[0028] Furthermore, a circular hole 2 is provided at the center of the horizontal plate 1. The diameter of the circular hole 2 is slightly larger than the diameter of the impeller hub. When the impeller is placed on the horizontal plate 1, the impeller hub is inserted into the circular hole 2. This not only improves the stability of the impeller, but also reduces the total height of the impeller after placement.

[0029] Furthermore, to facilitate the external traction mechanism to pull the transfer device, a traction hole 3 is provided on the horizontal plate 1. Two traction holes 3 are provided, and the two traction holes 3 are symmetrically arranged with respect to the perpendicular bisector of the isosceles triangle formed by the line connecting the three transport tanks 10. When the traction mechanism pulls, a traction rope can be tied in the traction hole 3. The traction mechanism can be implemented using existing power machinery.

[0030] Furthermore, the specific structure of the aforementioned hoisting mechanism includes a fixed pulley 4, which is located on the roof of the pump house 6 above the impeller of the water pump unit. Multiple fixed pulleys 4 can be installed as needed. When multiple fixed pulleys 4 are installed, they are spaced apart on the roof of the pump house 6. A steel wire rope 5 is wound around the fixed pulley 4. One end of the steel wire rope 5 is a free end, and the other end is tied to the impeller. The free end of the steel wire rope 5 can be connected to other traction machinery, and the impeller can be pulled by the traction machinery. Alternatively, it can be wound with an electric wire roller, and the impeller can be placed on the horizontal plate 1 by the electric wire roller winding and unwinding the wire.

[0031] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0032] Any aspects of this utility model not described in detail are known to those skilled in the art.
