Description

Technical Field

[0001] The invention relates to the technical field of double-casing pump processing, in particular to a double-casing pump core package disassembly tool. Background Art

[0002] With the development of petrochemical industry, large double-casing pumps are more and more widely used. However, due to the large size and heavy weight of such pumps, especially the difficulty and high requirements of installation and disassembly of double-casing pump core packs, it has become a major problem for after-sales personnel to carry out loading and unloading maintenance on site. In the prior art, tripod suspension or support plates under the pump body are usually used to assist in disassembly and assembly. The on-site operation is difficult, the safety is poor, the operation is time-consuming and labor-intensive, and the efficiency is low. Therefore, a new type of easy-to-operate disassembly and assembly tool is urgently needed to assist on-site after-sales personnel in maintenance work. Summary of the invention

[0003] The purpose of the present invention is to provide a double-shell pump core package disassembly tool, which has the advantages of simple structure, good stability, high reliability, simple and convenient use, good safety and high efficiency, and solves the problems in the prior art.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a double-shell pump core package disassembly tool, comprising a connecting plate 6 and a fixing plate 9, wherein the connecting plate 6 and the fixing plate 9 are both open arc-shaped plates; the connecting plate 6 and the fixing plate 9 are connected to each other by a first longitudinal beam 7 and a second longitudinal beam 8; the end surface of the connecting plate 6 away from the fixing plate 9 is provided with a first support rod 1, a second support rod 2, and a third support rod 5, the ends of the first support rod 1, the second support rod 2, and the third support rod 5 away from the connecting plate 6 are all connected to a connector 4, a lifting ring 3 is screwed on one end of the connector 4 adjacent to the connecting plate 6, a plurality of connecting holes 13 are evenly distributed on the fixing plate 9, a sleeve 10 is movably fitted inside the connecting hole 13, and a step 16 abutting against the end surface of the connecting hole 13 is provided on the sleeve 10.

[0005] Through the above arrangement, when in use, a sleeve that matches the thickness of the pump cover is selected and installed in the connecting hole of the fixed plate. After the pump cover of the double-shell pump is removed, the sleeve is inserted into the stud on the end face of the double-shell pump body, and then the nut is screwed into the screw from the sleeve end and tightened, and the fixed plate is pressed against the end face of the double-shell pump body to form a solid whole with the pump body. Then the electric hoist or manual hoist is fixed to the lifting ring, and the core bag is connected and pulled with its traction rope to pull the core bag out. The pulled-out core bag is slidably supported by the first longitudinal beam and the second longitudinal beam, which is simple and convenient to operate, saves labor and time, and can also prevent the core bag from being damaged, providing good safety protection for operators. With an open semi-circular arc structure, the core bag can be easily maintained after being pulled out of the pump body.

[0006] Furthermore, the second longitudinal beams 8 have two and are respectively disposed at the openings of the connecting plate 6 and the fixing plate 9 .

[0007] Through the above arrangement, the second longitudinal beam supports the core pack pulled out of the pump body to prevent the core pack from rolling and falling, and at the same time strengthens the rigidity of the first longitudinal beam and the entire tool, which is stable and safe.

[0008] Furthermore, a reinforcing plate 11 is longitudinally provided on the second longitudinal beam 8 , and a plurality of hollow holes 12 are evenly distributed on the reinforcing plate 11 .

[0009] Through the above arrangement, the reinforcing plate increases the rigidity and strength of the second longitudinal beam, and the hollow holes make the reinforcing plate have the advantages of high strength and light weight.

[0010] Furthermore, a plurality of reinforcement blocks 14 are evenly distributed inside the second longitudinal beam 8 .

[0011] Through the above arrangement, the reinforcing block increases the stability of the second longitudinal beam while reducing the friction of the core pack on the second longitudinal beam, making it easier to remove the core pack.

[0012] Furthermore, a reinforcing rib 15 is provided on the outer side of one end of the second longitudinal beam 8 adjacent to the fixing plate 9 .

[0013] Through the above arrangement, the reinforcement ribs are arranged to make the connection between the longitudinal beam and the fixed plate more firm, the supporting capacity is better, and the safety is good.

[0014] Furthermore, the first longitudinal beam 7 is an I-beam, and the cross section of the second longitudinal beam 8 is L-shaped.

[0015] Through the above arrangement, the first longitudinal beam and the second longitudinal beam have the advantages of high strength and light weight, so that the tool of the present invention is light and labor-saving to use.

[0016] Furthermore, the first support rod 1, the second support rod 2, and the third support rod 5 form a triangular support structure.

[0017] Through the above arrangement, when the core package is pulled, the reaction force is transmitted to the first support rod, the second support rod, and the third support rod through the lifting ring and the connector, and then evenly transmitted to the connecting plate. The stress distribution is uniform, so that the tool of the present invention is stable and has a long service life.

[0018] Beneficial effects of the present invention: The double-shell pump core package disassembly tool provided by the present invention has the advantages of simple structure, good stability, high reliability, simple and convenient use, good safety and high efficiency.
