Description

Technical Field

[0001] This utility model belongs to the technical field of pump dismantling equipment, specifically involving a combined adjustable pump dismantling and lifting fixture. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the metallurgical, power, and chemical industries, a large number of pumps and skid-mounted equipment are installed. These devices undergo secondary grouting during installation to enhance stability. In harsh installation environments or when significant vibrations or impacts during equipment operation demand high base stability, some equipment even undergoes tertiary grouting of the base cavity. Pumps often require complete replacement due to wear or process flow adjustments. Pump replacement presents several challenges: 1. Pumps are typically replaced entirely during major overhauls, resulting in a short timeframe; 2. Pumps are usually located on the ground beneath pipe racks or frames, surrounded by numerous process pipelines, creating limited operational space and hindering the use of large machinery; 3. Equipment dismantling requires separating the base from the secondary grouting layer. For equipment with tertiary grouting of the base cavity, separation is even more difficult due to the grout material's bonding with the foundation.

[0004] The existing pump disassembly fixture includes a base and a pump. A fixing plate is fixedly connected to the top left of the base, and the fixing plate fits against the pump. A first bracket is fixedly connected to the right end of the fixing plate, and the first bracket fits against the pump. A connecting plate is slidably connected to the inner side of the first bracket, and the connecting plate fits against the base. A second bracket is fixedly connected to the right end of the connecting plate, and the second bracket fits against the pump. A horizontal shaft is fixedly connected to the top right of the second bracket, and a push shaft is provided on the inner side of the horizontal shaft. Through the base, fixing plate, second bracket, and baffle, the operator places the pump onto the first bracket, fitting it against one side of the fixing plate. The other side of the pump is positioned and clamped by a spring-driven baffle, preventing pump displacement during disassembly. However, this fixture is not applicable to situations with limited space and difficult separation. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a combined adjustable pump and motor dismantling and lifting fixture.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: This utility model provides a combined adjustable pump and motor dismantling and lifting fixture, including: A supporting beam; Two clamps are slidably fitted onto both ends of the support beam. The clamps are provided with through holes for the support beam to pass through, thereby allowing adjustment of the position of the clamps on the support beam.

[0011] Preferably, the path of the through hole in the clamp is inclined to the clamp surface, and the angle between the center line of the through hole and the extended line of the upper surface of the hook head in the direction of the hook head is 0~30°. During lifting, guiding the tops of the clamps at both ends to tilt inward helps to more firmly clamp the pump between the two clamps.

[0012] Preferably, the reinforcing structure is a reinforcing rib plate welded to the lower surface of the hook head.

[0013] Preferably, the lifting structure is a jack.

[0014] Preferably, the jack is a threaded jack. This device allows for easy manual dismantling of the pump without the need for electricity, reducing energy consumption and the need for other equipment, thus requiring less space.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] In some embodiments, the present invention provides a combined adjustable pump dismantling and lifting fixture, comprising: a support beam; two clamps slidably fitted onto both ends of the support beam, the clamps having through holes for the support beam to pass through, thereby allowing adjustment of the clamps' position on the support beam; hooks disposed on the clamps, the hooks being cross-fixedly connected to the clamps for combining with the support beam and clamps to fix the pump to be dismantled; in use, the fixture is assembled, with the hooks on the two clamps positioned opposite each other; a reinforcing structure disposed below the hooks and fixedly connected to the hooks and clamps respectively; and two lifting structures disposed below both ends of the support beam for providing lifting force.

[0027] In some embodiments, the through holes on the clamp are circular, square, semi-circular, or irregular in shape. The shape of the through holes on the clamp is adapted to the cross-sectional shape of the support beam.

[0028] In some embodiments, the size of the through hole on the fixture is larger than the outer contour size of the cross-section of the support beam, and the gap between the two is 1mm to 2mm.

[0029] In some embodiments, the support beam is an I-beam or an H-beam, and the through hole on the clamp is I-shaped or H-shaped.

[0030] In some embodiments, the path of the through hole in the fixture is inclined to the fixture surface, and the angle between the center line of the through hole and the extension line of the upper surface of the hook head in the direction of the hook head is 0~30°.

[0031] In some embodiments, the reinforcing structure is a reinforcing rib plate welded to the lower surface of the hook head.

[0032] In some embodiments, the lifting structure is a jack, more preferably a threaded jack, which is easy to operate manually and requires no electricity.

[0033] In some embodiments, grooves are provided on the bottom surface of both ends of the support beam to accommodate the jack rods and prevent the jack from slipping.

[0034] Example 1 The structure of the combined adjustable pump and jacking fixture for dismantling is as follows: Figures 1-4 As shown, it includes a support beam 2 and two clamps 1. The support beam 2 can be made of I-beams or H-beams. The specifications and length of the steel section can be appropriately selected according to the width of the pump base and the weight of the pump. In principle, the steel section is larger than the width of the equipment base, and can be adjusted to suit pumps of different widths.

[0035] The clamp 1 is made of a 300mm×300mm×20mm thick steel plate. The clamp 2 has a through hole 201 for the support beam 2 to pass through. The size of the through hole 201 should preferably exceed the cross-sectional profile of the steel section by about 2mm-4mm. As a typical embodiment, the support beam can be HW150×150 steel or I-beam 16 steel. The size of the through hole 201 of the clamp is slightly larger than the cross-sectional dimensions of the HW150×150 steel or I-beam 16 steel.

[0036] Each clamp 1 is welded with two 125mm×60mm×20mm hooks 3 on the left and right. When in use, the two hooks 3 are set opposite each other, and the lower part of the hooks is reinforced with 60mm×60mm×20mm reinforcing ribs 4 that are perpendicular to each other.

[0037] Figure 3 The overall effect of this utility model is shown. In use, the HW150×150 support beam 2 is placed directly on the pump base 7, keeping the main shaft vertical. Both ends of the support beam 2 extend at least 200mm beyond the equipment foundation. Clamps 1 are inserted into both ends of the support beam 2, with hooks 3 facing inwards and locking below the edge of the channel steel of the pump base 7, ensuring good contact. Threaded jacks 5 are installed at both ends of the support beam 2 to lift the support beam 2 and the pump base 7, thereby detaching the pump base 7 along with the pump 6 from the concrete.

[0038] Example 2 like Figure 2 As shown, each clamp 1 is welded with a hook head 3, and a 60mm×60mm×20mm reinforcing rib plate 4 perpendicular to the hook head 3 is welded to the lower part of the hook head 3 for reinforcement.

[0039] Example 3 During use, to prevent jack 5 from slipping off the bottom surface of support beam 2, such as Figure 4 As shown, grooves 202 are provided on the bottom surfaces of both ends of the support beam 2, and the jack rod of the jack 5 is embedded in the grooves 202, so that the positions of the two are more fixed during the lifting process.

[0040] Example 4 To further improve the compatibility between clamp 1 and support beam 2, such as Figure 5 As shown, the path of the through hole in the fixture is inclined to the fixture surface, and the angle between the center line of the through hole and the extension line of the hook head in the direction of the hook head is 0~30°.

[0041] 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, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
