Description

Technical Field

[0001] The utility model relates to the technical field of pump body hoisting, in particular to a multi-part hoisting device for a pump body. Background Technique

[0002] A pump is a machine that transports fluids or increases the pressure of fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid-base solutions, emulsions, suspensions, and liquid metals, and can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps can generally be classified into three categories according to the working principle: positive displacement pumps, dynamic pumps, and other types of pumps. In addition to classification by working principle, they can also be classified and named by other methods. For example, according to the driving method, they can be divided into electric pumps and water turbine pumps, etc.; according to the structure, they can be divided into single-stage pumps and multi-stage pumps; according to the use, they can be divided into boiler feed pumps and metering pumps, etc.; according to the nature of the transported liquid, they can be divided into water pumps, oil pumps, and mud pumps, etc. According to the presence or absence of a shaft structure, they can be divided into linear pumps and traditional pumps. A water pump can only transport logistics with fluid as the medium and cannot transport solids.

[0003] For the above various pump bodies, generally, they all include a discharge port and a feed port, and flange plates are provided at both the discharge port and the feed port for pipeline connection. In the prior art, when hoisting a pump body, a binding strap is generally used to fix the pump body. Therefore, during the hoisting process, there is a defect that the pump body is not fixed stably, which easily causes the pump body to fall and be damaged. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-part hoisting device for a pump body with a simple structure, convenient installation and replacement, and high stability for the pump body.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-part hoisting device for a pump body includes a suspension plate and a chassis detachably connected to the suspension plate. It is characterized in that a connecting rod is passed through between the suspension plate and the chassis, and several connecting rods are arranged along the circumferential direction of the suspension plate.
