Description

Technical Field

[0001] The utility model relates to the field of installation of water pumps and pump groups, in particular to an auxiliary installation vertical platform for a vertical pump. Background Art

[0002] A vertical pump is a pump that remains in a vertical position when working. However, during the assembly and transportation process, if the vertical pump remains in an upright position, there will be a great safety hazard. Therefore, the vertical pump needs to be in a horizontal position during the above process. Therefore, when installing a vertical pump or a vertical pump group composed of multiple vertical pumps, the posture of the vertical pump needs to be adjusted first, so that it can be rotated from a horizontal position to a vertical position.

[0003] In the traditional way, lifting equipment is generally used to adjust the posture, but both vertical lifting equipment and horizontal lifting equipment need to occupy a large overhead space. If the space is small or there is a height limit, the above lifting equipment often cannot be used normally.

[0004] Moreover, the key to the lifting process is the leveling of the heavy object. There are two commonly used leveling methods: the mobile rope leveling method and the chain leveling method, but both methods have the problem of being too large and the lifting extension is too long. Therefore, once the space does not allow, the traditional method can only be operated by lifting the pump on one side with a forklift and binding the pump body to fix it. This method has a great safety hazard and it is difficult to ensure the installation accuracy.

[0005] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0006] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes an auxiliary installation vertical platform which has a simple structure, ingenious design, reasonable layout, and does not require much operating space, and can achieve adjustment of the pump body from a horizontal posture to a vertical posture while ensuring safety and accuracy.

[0007] The technical solution of the utility model is: a vertical pump auxiliary installation vertical platform, including a basic platform 1, characterized in that: the middle part of the basic platform 1 is hinged with a flip mechanism through a rotating shaft 2, and the two ends of the basic platform 1 are respectively provided with a rope adjustment mechanism and a support plate 20,

[0008] The flip mechanism includes a rotating body, and the rotating body includes a driving part 3 and a supporting part 4 that are distributed at obtuse angles to each other. A horizontally distributed driving cylinder 5 is provided on the basic platform 1. The end of the driving shaft of the driving cylinder 5 is rotatably connected to a slider 6. The slider 6 is slidably connected to a first slide groove 7 provided on the driving part 3. A telescopic plate 9 is connected to the supporting part 4 through a scissor-type lifting mechanism 8. A clearance notch is provided on the supporting part 4 and the telescopic plate 9, that is, the two are in a concave shape. A limiting platform 10 matching the supporting part 4 is also provided on the basic platform 1.

[0009] The scissor lift mechanism 8 includes an electric push rod 11 connected to the support part 4, the output shaft of the electric push rod 11 is hinged to a fulcrum on the A side of the scissor assembly 12, and the other fulcrum on the A side is slidably connected to the second slide groove 13. The slide groove block 14 where the second slide groove 13 is located is fixedly connected to the support part 4, and the two fulcrums on the B side of the scissor assembly 12 are slidably connected to the third slide groove 15 opened on the telescopic plate 9.

[0010] The rope adjustment mechanism is composed of two symmetrically distributed adjustment components, which include a fixed pulley 16 and a retractable reel 17 rotatably supported on the base platform 1. The retractable reel 17 is driven by a servo motor, and an adjustment rope 18 is wound around the retractable reel 17.

[0011] The two ends of the adjustment rope 18 are connected to the two retractable reels 17 respectively. The adjustment rope 18 is wound around the fixed pulley 16 and is also movably connected to the guide groove provided on the guide block 19. The guide block 19 is provided at the end of the support part 4.

[0012] An auxiliary bracket 21 is also provided on one end of the base platform 1 close to the support plate 20 .

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] This type of structural form of vertical pump auxiliary installation vertical platform has a simple structure, ingenious design, and reasonable layout. It is designed to solve the problems existing in the traditional vertical pump posture adjustment. It can use the rope adjustment mechanism to adjust the tilted vertical pump to a horizontal state, and then the telescopic plate in the flipping mechanism is extended. The telescopic plate can be connected to the mounting plate on the vertical pump, and then the vertical pump can be driven to flip from a horizontal state to a vertical state in space. Its flipping radius is relatively small, and no lifting equipment is required. Therefore, it can be used under relatively small working conditions of the elevated space, and can realize the automatic flipping action of the vertical pump. Compared with the traditional method that requires personnel assistance, it effectively eliminates safety hazards. At the same time, its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown: A vertical pump auxiliary installation vertical platform includes a basic platform 1, a flip mechanism is hinged in the middle through a rotating shaft 2, and rope adjustment mechanisms and support plates 20 are respectively provided at both ends of the basic platform 1.

[0020] The flip mechanism includes a rotating body, and the rotating body includes a driving part 3 and a supporting part 4 that are distributed at obtuse angles to each other. A horizontally distributed driving cylinder 5 is provided on the basic platform 1. The end of the driving shaft of the driving cylinder 5 is rotatably connected to a slider 6. The slider 6 is slidably connected to a first slide groove 7 provided on the driving part 3. A telescopic plate 9 is connected to the supporting part 4 through a scissor-type lifting mechanism 8. A clearance notch is provided on the supporting part 4 and the telescopic plate 9, that is, the two are in a concave shape. A limiting platform 10 matching the supporting part 4 is also provided on the basic platform 1.

[0021] The scissor lift mechanism 8 includes an electric push rod 11 connected to the support part 4, the output shaft of the electric push rod 11 is hinged to a fulcrum on the A side of the scissor assembly 12, and the other fulcrum on the A side is slidably connected to the second slide groove 13. The slide groove block 14 where the second slide groove 13 is located is fixedly connected to the support part 4, and the two fulcrums on the B side of the scissor assembly 12 are slidably connected to the third slide groove 15 opened on the telescopic plate 9.

[0022] The rope adjustment mechanism is composed of two symmetrically distributed adjustment components, which include a fixed pulley 16 and a retractable reel 17 rotatably supported on the base platform 1. The retractable reel 17 is driven by a servo motor, and an adjustment rope 18 is wound around the retractable reel 17.

[0023] The two ends of the adjustment rope 18 are connected to the two retractable reels 17 respectively. The adjustment rope 18 is wound around the fixed pulley 16 and is also movably connected to the guide groove provided on the guide block 19. The guide block 19 is provided at the end of the support part 4.

[0024] An auxiliary bracket 21 is also provided on one end of the base platform 1 close to the support plate 20 .

[0025] The working process of the vertical pump auxiliary installation vertical platform of the embodiment of the utility model is as follows: when the vertical pump 22 needs to be installed, since the vertical pump 22 needs to be placed horizontally during transportation, it needs to be flipped to a vertical state;

[0026] First, use a forklift or other transporting tool to carry the horizontal vertical pump 22 to the platform, so that the mounting plate 23 on the vertical pump 22 is supported on the auxiliary bracket 21, and the bottom end of the vertical pump 22 is placed on the support plate 20 (the adjustment rope 18 is placed under the vertical pump 22 in advance). At this time, the vertical pump 22 is in an inclined distribution state;

[0027] The servo motor is controlled by the control system to drive the reel 7 to rotate, tighten the adjustment rope 18, and make the adjustment rope 18 stuck in a ring on the outer wall of the vertical pump 22. The adjustment rope 18 is further tightened, and the adjustment rope 18 will pull one end of the vertical pump 22 upward. Through the precise control of the servo motor, assisted by tools such as a level, the vertical pump 22 is finally adjusted to a state where its axis remains horizontal.

[0028] Then, the control system controls the electric push rod 11 to work, and the electric push rod 11 drives the scissor assembly 12 to move, driving the telescopic plate 9 to move in the direction of the mounting plate 23. Since a gap is provided on the telescopic plate 9, it will not interfere with the vertical pump 22 during its movement. After the telescopic plate 9 moves to the position in contact with the mounting plate 23, the electric push rod 11 is controlled to stop moving. After the telescopic plate 9 and the mounting plate 23 are connected as an integrated structure by bolts, the control system controls the drive cylinder 5 to be recovered, and the slider 6 of the drive cylinder 5 drive shaft slides in the first slide groove 7, and pulls the drive part 3 to rotate, thereby driving the rotating body to rotate as a whole. During the above-mentioned action, the servo motor will also drive the retracting and unreeling reel 17 to reel, so that the adjustment rope 18 always pulls the end of the vertical pump 22. Since the adjustment rope 18 is inclined, it is equivalent to generating a component force parallel to the telescopic direction of the scissor assembly 12. This component force can ensure that during the flipping process, the scissor assembly 12 can stably support the vertical pump 22;

[0029] When the vertical pump 22 is flipped from a horizontal state to a vertical state, the electric push rod 11 moves in the opposite direction, the scissor assembly 12 retracts, and the mounting plate 23 drives the vertical pump 22 downward until the scissor assembly 12 is in a completely recovered state, and then the bolts between the telescopic plate 9 and the mounting plate 23 are removed, and the vertical pump 22 is removed from the device in a vertical posture using a forklift or other device, and the vertical pump 22 can be installed.
