Description

Technical Field

[0001] The invention belongs to the technical field of long-axis vertical pump hoisting, and particularly relates to a device for hoisting a long-axis vertical pump and a hoisting method thereof. Background Art

[0002] Long-axis vertical pumps are widely used in various industrial fields. In the field of underground water supply, long-axis vertical pumps are used inside the factory. Due to space limitations, the vertical pump can only be installed and disassembled using the crane inside the factory as a lifting tool. The long-axis vertical pump is 8.5 meters long, while the maximum lifting height from the ground vertical pump lifting hole to the main lifting hook of the crane is only 7 meters. The lifting height is limited. In existing technical solutions, such as Figure 5 As shown, during installation, the vertical pump cannot be lifted vertically. The lifting point needs to be adjusted to the inclined lifting point B, and the tilt angle must be within the range of the lifting hole width. After the lifting point is set, the vertical pump bottom filter is lifted from the ground lifting hole to the underground pool concrete surface 13, placed in a free state, the vertical pump tilt lifting point is released, and the lifting point is set to the dedicated vertical lifting point A of the pump unit in the vertical pump. Normal lifting begins, completing the lifting of the pump unit. Similarly, when dismantling a long-axis vertical pump, the vertical pump is first lifted vertically at the vertical lifting point A. After the entire vertical pump is lifted, the pump bottom filter is lowered into the pool surface concrete, and the pump head is tilted against one side of the ground lifting hole. After being placed in a free state, the lifting point is set at the pump unit inclined lifting point B, and tilted lifting begins out of the ground lifting hole, completing the dismantling of the entire pump unit.

[0003] The above-mentioned prior art solutions have the following disadvantages:

[0004] 1. The vertical pump components need to be hoisted multiple times, which is risky and takes a long time to hoist.

[0005] 2. When the pump unit is placed during hoisting, the pump body is in an inclined state, and the pump bottom filter is lowered onto the concrete surface of the pool, causing uneven force on the bottom filter screen, which eventually leads to damage to the pump unit filter screen;

[0006] 3. When the pump unit is hoisted for the second time, the operator needs to change the lifting point on the ground of the lifting hole and perform binding operations, which may cause the risk of falling from a height;

[0007] 4. The pump body is placed in the sludge for a long time, and a large amount of sludge and oil dirt adheres to the pump body. When the pump body is lifted out, a large amount of sludge and oil dirt is also attached to it, causing great pollution and damage to the work site;

[0008] 5. When the pump unit is lifted or installed, when the pump body passes through a narrow lifting hole, the pump body is likely to collide with the edge of the hole, causing damage to the pump body, or the concrete at the edge of the hole collapses, causing various equipment accidents and height-falling accidents. Summary of the Invention

[0027] A second aspect of the present invention provides a method for hoisting the device described in the first aspect, comprising:

[0028] (a) Lifting

[0029] First adjust the arc-shaped support plate 5 to a vertical state;

[0030] Place the lifting device of the crane 12 into the lifting hole, and lift the long-axis vertical pump vertically upward from the underground water tank until the outlet pipe and the first section of the pump body bearing seat 401 on the long-axis vertical pump are lifted out of the ground lifting hole, and the height of the pump body bearing seat 401 is higher than the top height of the vertical state of the arc-shaped support plate 5. At this time, stop the lifting device of the crane 12 from continuing to move upward;

[0031] Rotate the arc-shaped support plate 5 to a horizontal state so that the two arc-shaped support plates 5 arranged in pairs clamp and support the pump body 4 through their arc-shaped structures;

[0032] Then, the pump body 4 is controlled to descend by the crane 12 so that the first section of the pump body bearing seat 401 is supported on the arc-shaped support plate 5. At the same time, the baffle 11 is naturally supported on the pump body 4 for positioning to prevent the pump body 4 from sliding toward the inclined surface.

[0033] Transfer the lifting device of the crane 12 and lift the long-axis vertical pump upwards;

[0034] After the pump body 4 continues to rise, when the second-section pump body bearing seat 401 is at the lower part of the arc-shaped support plate 5, the pump body 4 continues to rise, and the second-section pump body bearing seat 401 pushes the arc-shaped support plate 5 upward without obstruction, and under the action of the buffer mechanism 8, the arc-shaped support plate 5 rotates upward at an angle less than 90°; when the second-section pump body bearing seat 401 is higher than the arc-shaped support plate 5, the arc-shaped support plate 5 automatically falls back to a horizontal state under its own weight, clamping and supporting the pump body 4; repeat this step until the entire long-axis vertical pump is hoisted upward.

[0035] Preferably, while the arc-shaped support plate 5 clamps and supports the pump body 4 , the sludge removing mechanism 6 automatically scrapes off the grease on the surface of the pump body 4 as the pump body 4 rises as a whole.

[0036] Preferably, the hoisting method further comprises:

[0037] (b)Reinstallation

[0038] Rotate the arc-shaped support plate 5 to a vertical state;

[0039] Use the crane 12 to tilt the long-axis vertical pump down to the hoisting hole until the first section of the pump body bearing seat 401 is higher than the top height of the vertical arc support plate 5. At this time, adjust the arc support plate 5 to fit the foundation base plate 1.

[0040] The long-axis vertical pump continues to be lowered until the first section of the pump body bearing seat 401 is completely fitted with the arc-shaped support plate 5, and the baffle 11 prevents the pump body 4 from sliding down in the inclined direction;

[0041] After the long-axis vertical pump is placed firmly, adjust the lifting point of the crane 12 to a vertical lifting state, and vertically lift the long-axis vertical pump through the crane 12 until the lifting height is greater than the height of the arc-shaped support plate 5 when it is vertically opened, and then stop lifting;

[0043] The present invention provides an arc-shaped support plate with a specific arc structure that can rotate no more than 90 degrees.

[0056] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0057] In the present invention, unless otherwise specified, the direction closer to the hoisting hole is considered as the inner side, and the opposite direction is considered as the outer side. Figure 1 and Figure 4 As shown in the concave arc structure.

[0058] The first aspect of the present invention provides a device for hoisting a long-axis vertical pump, such as Figures 1-4 Shown, including:

[0059] Basic bottom plates 1, which are arranged in pairs and distributed on opposite sides of the lifting holes (not shown in the figure), and are fixed on the ground 9;

[0060] An arc-shaped support plate 5, which corresponds one-to-one with the basic base plate 1, and one end of which is rotatably connected to the basic base plate 1, and the other end is a concave arc structure, and the curvature of the arc structure is greater than the corresponding curvature of the pump body 4 of the long-axis vertical pump, and smaller than the corresponding curvature of the pump body bearing seat 401 of the long-axis vertical pump; when used for hoisting, the arc-shaped support plate 5 can be connected to the pump body 4 in the circumferential direction through the arc structure to form a stable support, and can also be located at the lower part of the pump body bearing seat 401 to form a stable support to prevent falling from a high altitude or facilitate replacement of the lifting point;

[0061] a buffer mechanism 8, which is provided on the base plate 1 and located outside the arc-shaped support plate 5, and is used to rotate the arc-shaped support plate 5 inward by no more than 90 degrees and to provide buffering;

[0062] The baffle 11 is provided on the arc support plate 5 and is used to support and position the pump body 4 when the arc support plate 5 is located at the lower part of the pump body bearing seat 401 to form a stable support. Figure 1 and Figure 2 As shown, the baffle 11 is arranged on the arc-shaped support plate 5 on the inclined side of the pump body 4.

[0063] In the device of the present invention, the arc-shaped support plate 5 has the function of automatically flipping upward in one direction and automatically falling back 90° downward. The one-way flipping and specific arc-shaped structure of the arc-shaped support plate 5 enable the pump body 4 to be stably supported. If it accidentally slips during lifting, the pump body bearing seat 401 will be supported by the arc-shaped support plate 5, which can prevent the lifting equipment from accidentally slipping and improve safety. The arc-shaped support plate 5 tightly clamps and supports the pump body 4, improving the stability of the pump body during the lifting process and improving safety.

[0064] The long-axis vertical pump described in the present invention is a prior art, such as Figure 2 and Figure 5 As shown, it includes a pump body 4, on which a plurality of pump body bearing seats 401 are arranged at intervals, a pump body outlet flange 403 is also arranged on the side of the head of the pump body 4, and a pump body motor connecting flange 402 is arranged on the head of the pump body 4.

[0065] It can be understood that the arc-shaped support plates 5 are arranged in pairs and distributed on two opposite sides of the hanging hole.

[0066] The base plate 1 mainly bears the weight of the pump body 4 during lifting, and is installed in the ground 9. The preferred installation method is to drive expansion bolts into the base plate 1 to fix it.

[0067] In some preferred embodiments, the device also includes: an oil sludge removal mechanism 6, which is arranged on the inner concave surface of the arc structure, and is used to automatically remove the oil sludge on the pump body 4 while the arc structure is clamped on the pump body 4 and moves with the hoisting of the long-axis vertical pump.

[0068] More preferably, the sludge removal mechanism 6 includes: an oil scraper and a fixed soft adhesive, the fixed soft adhesive being attached to the surface of the oil scraper, and the oil scraper being attached to the inner concave surface of the arc structure. Preferably, the oil scraper is made of wear-resistant canvas adhesive and is clamped to the edge of the arc support plate 5.

[0069] Preferably, the inner concave diameter of the arc structure is slightly larger than the diameter of the pump body 4 of the long-axis vertical pump, which is more conducive to efficient cleaning of oil stains on the pump body 4 and can be more firmly placed on the arc support plate 5 after the pump body 4 is hoisted.

[0070] In some preferred embodiments, Figure 1 and Figure 4As shown, a plurality of arc-shaped grooves are provided on the arc-shaped structure, and the arc-shaped grooves are extended along the curvature of the arc-shaped structure. In this preferred embodiment, the weight of the arc-shaped support plate 5 can be greatly reduced, and the friction force of the pump body 4 when it is located on the arc-shaped support plate 5 can be increased, thereby preventing the pump body 4 from slipping. Among them, for example, the arc-shaped support plate 5 can be made of high-strength aluminum alloy, which has both good mechanical compressive properties and a good friction coefficient. The arc-shaped grooves give the arc-shaped structure a certain elasticity. When combined with the optional elastomer, the friction force is increased when the pump body 4 is elastically squeezed, thereby preventing the pump body 4 from slipping. At the same time, it is closely matched with the pump body 4 to prevent the pump body 4 from shaking, thereby improving the stability of the pump body 4 during the lifting process.

[0071] In some preferred embodiments, the upper surface of the foundation plate 1 is tilted, and its tilt direction is consistent with the tilt direction of the long-axis vertical pump during hoisting. The foundation plate 1 can be tilted as a whole, or only the upper surface can be tilted, with the lower surface supported and connected to the ground 9.

[0072] In some preferred embodiments, the device further comprises: a support rod 10 , wherein the support rod 10 is installed between the base plate 1 and the ground 9 .

[0073] In some preferred embodiments, the device further comprises: a fixed base 3 fixed to the base plate 1; and a rotating shaft 2, the end of which is rotatably connected to the fixed base 3 and detachably connected to the curved support plate 5. The curved support plate 5 and the rotating shaft 2 are detachably connected to form a single component. Once mounted on the base plate 1, this component should be capable of 90° rotation from horizontal to vertical. Preferably, the fixed base 3 is integrally connected to the base plate 1 by bolts.

[0074] The detachable connection is preferably a concave-convex snap-fit ​​connection, and a concave-convex embedded installation fixation is more convenient for disassembly and replacement. Among them, the concave-convex snap-fit ​​method is, for example, a convex steel bar is provided on the rotating shaft 2, and the connecting end of the arc-shaped support plate 5 (i.e., the opposite end of the arc structure) is provided with a concave straight edge, the depth of which matches the installation depth of the convex steel bar of the rotating shaft 2, and the size is perfectly matched thereto.

[0075] It is understandable that both ends of the rotating shaft 2 are disposed in the fixed base 3. Preferably, the rotating connection between the rotating shaft 2 and the fixed base 3 adopts a self-lubricating sliding bearing, which can bear a large load and does not require daily lubrication.

[0076] More preferably, the buffer mechanism 8 is vertically arranged on the base slab 1 .

[0077] Further preferably, the device also includes: a limit block 7, which is fixed on the rotating shaft 2 and arranged perpendicular to the arc-shaped support plate 5, and is located on the outside of the arc-shaped support plate 5, and is arranged one-to-one with the buffer mechanism 8, for allowing the arc-shaped support plate 5 to rotate inward only by no more than 90°.

[0078] The number of the buffer mechanism 8 can be set by those skilled in the art according to the requirements, as long as it plays its role. Figure 1 As shown, there are four groups of buffer mechanisms 8 , which are respectively installed at both ends of the arc-shaped support plate 5 .

[0079] Further preferably, the buffer mechanism 8 includes: a buffer rubber 801 and a buffer fixing sleeve 802 , the buffer fixing sleeve 802 is sleeved outside the buffer rubber 801 and fixed on the base floor 1 , and the buffer rubber 801 extends outward along the buffer fixing sleeve 802 .

[0080] Preferably, the buffer contact end of the buffer rubber 801 is a fan-shaped pancake structure, which is more conducive to reducing the wear of the buffer rubber 801, and the arc-shaped contact surface of the fan-shaped pancake structure can also better ensure its buffering effect.

[0081] Preferably, the buffer rubber 801 and the buffer fixing sleeve 802 are matched with each other by an interference fit hole to ensure the stability of the buffer rubber 801.

[0082] A second aspect of the present invention provides a method for hoisting the device described in the first aspect, comprising:

[0083] (a) Lifting

[0084] First adjust the arc-shaped support plate 5 to a vertical state;

[0085] Place the lifting device of the crane 12 into the lifting hole, hook it to the vertical lifting point A on the long-axis vertical pump, and lift it vertically from the underground water tank until the outlet pipe and the first section of the pump body bearing seat 401 on the long-axis vertical pump are lifted out of the ground lifting hole, and the height of the pump body bearing seat 401 is higher than the top height of the vertical state of the arc-shaped support plate 5. At this time, stop the crane 12 from continuing to move upward;

[0086] The arc-shaped support plate 5 is rotated to a horizontal state so that the two arc-shaped support plates 5 arranged in pairs can clamp and support the pump body 4 through their arc-shaped structures. Figure 2 As shown;

[0087] Then, the pump body 4 is controlled to descend by the crane 12 so that the first section of the pump body bearing seat 401 is supported on the arc-shaped support plate 5. At the same time, the baffle 11 is naturally supported on the pump body 4 for positioning to prevent the pump body 4 from sliding toward the inclined surface.

[0088] Transfer the lifting device of the crane 12 and lift the long-axis vertical pump upwards;

[0089] After the pump body 4 continues to rise, when the second-section pump body bearing seat 401 is at the lower part of the arc-shaped support plate 5, the pump body 4 continues to rise, and the second-section pump body bearing seat 401 pushes the arc-shaped support plate 5 upward without obstruction, and under the action of the buffer mechanism 8, the arc-shaped support plate 5 rotates upward at an angle less than 90°; when the second-section pump body bearing seat 401 is higher than the arc-shaped support plate 5, the arc-shaped support plate 5 automatically falls back to a horizontal state under its own weight, clamping and supporting the pump body 4; repeat this step until the entire long-axis vertical pump is hoisted upward.

[0090] Preferably, while the arc-shaped support plate 5 clamps and supports the pump body 4, the sludge removal mechanism 6 automatically scrapes away grease from the surface of the pump body 4 as the pump body 4 rises. It should be understood that the first section of the pump body 4 is at the highest point in the water tank and is free of grease. Therefore, the first section of the pump body 4 (i.e., the portion before the first section bearing seat 401) does not require grease removal.

[0091] Preferably, the hoisting method further comprises:

[0092] (b)Reinstallation

[0093] The arc-shaped support plate 5 is rotated to a vertical state, as shown in FIG. Figure 3 As shown;

[0094] Use the crane 12 to tilt the long-axis vertical pump down to the hoisting hole until the first section of the pump body bearing seat 401 is higher than the top height of the vertical arc support plate 5. At this time, adjust the arc support plate 5 to fit the foundation base plate 1.

[0095] The long-axis vertical pump continues to be lowered until the first section of the pump body bearing seat 401 is completely fitted with the arc-shaped support plate 5, and the baffle 11 prevents the pump body 4 from sliding down in the inclined direction;

[0096] After the long-axis vertical pump is firmly placed, loosen the tilted lifting point and set the lifting points of the pump body 4 on both sides symmetrically of the pump body motor connection flange 402 to ensure that the lifting points can keep the pump body 4 vertical. The hook of the crane 12 can continue to lift. Adjust the lifting point of the crane 12 to a vertical lifting state. Use the crane 12 to vertically lift the long-axis vertical pump until the lifting height is greater than the height of the arc-shaped support plate 5 when it is vertically opened, and then stop lifting.

[0097] After the arc-shaped support plate 5 is adjusted to a vertical state, the long-axis vertical pump is vertically lowered by the crane 12 to a desired position for installation.

[0098] It is understandable that during the reinstallation process, if Figure 3As shown, the pump body motor connection flange 402 of the pump body 4 is located in the middle of the arc-shaped support plates 5 on both sides to facilitate the hanging operation.

[0099] According to a specific embodiment of the present invention, Figures 1-4 As shown, the method of hoisting a long-shaft vertical pump is as follows:

[0100] 1. Lifting out the long-axis vertical pump:

[0101] like Figure 2 As shown, the arc support plate 5 is adjusted to the inclined side (i.e. the right side in the figure) to a vertical open state by adjusting the rotating shaft 2. At this time, the hook head of the crane 12 can be put into the ground lifting hole, and the lifting device is tied to both sides of the pump body outlet flange 403. After confirming that the lifting point is vertical to the hook head, the lifting can be carried out. After the pump body 4 is lifted out of the pool surface 13 lifting hole, the lifting is continued. When the pump body 4 outlet pipe and the first pump body bearing seat 401 of the pump body 4 are lifted out of the ground 9 lifting hole, and the height should be higher than the top height of the vertical state of the arc support plate 5, the upward movement of the crane 12 hook is stopped at this time. The arc support plate 5 is adjusted from a vertical 90 degree to a horizontal state by adjusting the rotating shaft 2. At this time, the arc support plate 5 is in a firm state under the interaction between the fixed base 3 and the concrete of the ground 9. The hook head of the crane 12 can be lowered so that the first pump body bearing seat 401 of the pump body 4 When the second section pump body bearing seat 401 is higher than the arc support plate 5, the arc support plate 5 will automatically fall back to the pump body 4 under its own weight, and the oil scraper at the arc mouth in the sludge removing mechanism 6 will automatically scrape off the oil stains on the surface of the pump body 4 as the pump body 4 rises as a whole, until the entire pump unit is lifted out.

[0102] 2. Long-axis vertical pump hoisted into the pool for installation:

[0103] like Figure 3As shown, the long-axis vertical pump is hoisted into the hoisting hole 9 on the ground in an inclined state, and the arc-shaped support plate 5 should be in a vertically open state. When the long-axis vertical pump enters the hoisting hole, and the entry length should be greater than the length of the first section pump body bearing seat 401, the arc-shaped support plate 5 can be adjusted to a horizontal closed state and fit with the foundation bottom plate 1, and the long-axis vertical pump continues to be lowered. When the first section pump body bearing seat 401 of the pump body 4 is completely fit with the arc-shaped support plate 5, and the baffle 11 is used to prevent the pump body 4 from sliding down in the inclined direction, after the long-axis vertical pump is placed firmly, loosen the inclined lifting point B, and set the pump body 4 lifting points on both sides of the pump body motor connecting flange 402 symmetrically to ensure that the lifting points can keep the pump body 4 vertical, and the hook can continue to lift upward. The lifting height should be greater than the height when the arc-shaped support plate 5 is vertically opened. When the height meets the requirements, stop lifting, and after the arc-shaped support plate 5 is adjusted to the vertically open state, continue to vertically lower the long-axis vertical pump to the required position for installation, thereby completing the reinstallation.

[0104] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner.
