Description

Technical Field

[0001] This utility model belongs to the field of maintenance equipment technology, and in particular relates to a low-pressure pump maintenance platform. Background Technology

[0002] As a core component of the liquefied natural gas (LNG) receiving terminal's transmission system, the low-pressure pump typically operates submerged within the LNG storage tank, along with its electric motor. Upon startup, the low-pressure pump draws in LNG from the bottom of the tank, pressurizes it, and then outputs it to the low-pressure output main through a pipeline connected to the top of the pump well. This ensures that the LNG inside the low-pressure pump maintains the same temperature as the LNG in the storage tank, effectively preventing vaporization within the pump. Therefore, routine maintenance and repair of the low-pressure pump are crucial in the design and operation of LNG receiving terminals.

[0003] Currently, the low-pressure pump is first hoisted from the storage tank to a maintenance platform, where it is then inspected and repaired. During maintenance, the low-pressure pump is placed upside down on the ground, with the maintenance platform surrounding it, requiring workers to stand on the maintenance work surface to operate. However, this maintenance method has several inconveniences: firstly, the height difference between the maintenance work surface and the ground makes it difficult for workers to climb up and down the platform; secondly, performing maintenance work on a higher work surface poses safety hazards.

[0004] Therefore, there is an urgent need for a low-pressure pump maintenance platform to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-pressure pump maintenance platform, which not only ensures the safety of the maintenance process, but also improves the convenience of maintenance for staff and their user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A low-pressure pump maintenance platform is provided, comprising:

[0008] The bracket can be detachably installed on the ground;

[0009] The maintenance workbench is set on the top of the support. The maintenance workbench is provided with limit holes. The low-pressure pump can be placed on the ground and pass through the limit holes. The wall of the limit hole and the outer wall of the low-pressure pump maintain a preset distance.

[0010] The first guardrail is installed on the maintenance workbench and extends circumferentially along the workbench. An access panel is provided on the first guardrail.

[0011] The staircase connects to the maintenance workbench at the top and extends to the ground at the bottom, with the top of the staircase located at the maintenance access point.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, this embodiment provides a low-pressure pump maintenance platform, which not only ensures the safety of the maintenance process, but also improves the convenience of maintenance for staff and their user experience.

[0034] See Figure 1 The low-pressure pump maintenance platform includes a support frame 1, a maintenance workbench 2, a first guardrail 3, and a staircase 4. The support frame 1 can be detachably installed on the ground. The maintenance workbench 2 is located on top of the support frame 1 and has a limiting hole 21. The low-pressure pump can be placed on the ground and pass through the limiting hole 21, and the wall of the limiting hole 21 maintains a preset distance from the outer wall of the low-pressure pump. The first guardrail 3 is located on the maintenance workbench 2 and extends along the circumference of the maintenance workbench 2. The first guardrail 3 has an inspection port 31. The upper end of the staircase 4 is connected to the maintenance workbench 2, and the lower end can extend to the ground. The upper end of the staircase 4 is located at the inspection port 31.

[0035] The low-pressure pump maintenance platform provided in this embodiment allows the low-pressure pump to be placed on the ground via the limiting hole 21, enabling workers to perform maintenance on the pump while standing on the maintenance workbench 2. This operation is convenient and simple. During maintenance, the low-pressure pump passes through the limiting hole 21, meaning the maintenance workbench 2 protects the pump from falling to the ground and causing damage, ensuring safety during maintenance. Furthermore, the gap between the wall of the limiting hole 21 and the outer wall of the low-pressure pump prevents the pump from colliding with the maintenance workbench 2 as it passes through, ensuring the service life of both the pump and the maintenance platform. The bracket 1 stably supports the maintenance workbench 2 on the ground, ensuring its stability and effectively preventing accidents during maintenance, thus improving safety. The first guardrail 3 prevents workers from falling from the maintenance workbench 2, ensuring the safety and health of those standing on it. The reserved access port 31 provides space for staff to access the maintenance workbench 2, making it convenient for staff to use. Staff can access the maintenance workbench 2 from the ground via the access port 31 through the stairs 4 to perform maintenance on the low-pressure pump without having to climb the maintenance workbench 2, which improves the convenience of maintenance and the user experience for staff.

[0036] For example, see Figure 1 The maintenance workbench 2 adopts a flat plate structure.

[0037] Optionally, see Figure 1 The support frame 1 includes multiple columns 11 spaced circumferentially along the maintenance workbench 2. Multiple connecting rods 12, arranged vertically at intervals, are provided between any two adjacent columns 11. The columns 11 and connecting rods 12 form a planar frame structure, allowing the support frame 1 to more flexibly adapt to maintenance workbench 2 with different cross-sectional shapes, thus stably supporting the workbench 2. Furthermore, the cross-sectional dimensions of the maintenance workbench 2 can be appropriately increased to provide sufficient space for the temporary placement of maintenance tools. In addition, the planar frame structure gives the support frame 1 high rigidity, making it less prone to damage and improving the durability of the low-pressure pump maintenance platform.

[0038] Specifically, see Figure 1 The support 1 has a reinforced column 11 area at the corner of the maintenance workbench 2, that is, the number of columns 11 at the corner of the maintenance workbench 2 is greater than the number of columns 11 at other locations, in order to further improve the rigidity of the support 1 and enable it to support the maintenance workbench 2 more stably.

[0039] For example, the height of the column 11 is in the range of 1000mm to 1500mm, that is, the distance from the maintenance workbench 2 to the ground is 1000mm to 1500mm. The specific height of the column 11 needs to be determined according to the model of the low-pressure pump to be maintained.

[0040] In this embodiment, see Figure 1 The support frame 1 also includes multiple pads 13, which correspond one-to-one with multiple columns 11. The pads 13 are set at the bottom of the corresponding columns 11 to increase the contact area between the columns 11 and the ground, so that the pressure on the columns 11 can be more evenly distributed on the ground, avoiding problems such as ground collapse or column tilting caused by excessive local pressure, ensuring the stability of the overall structure of the support frame 1, and ensuring the safety of the personnel performing maintenance on the maintenance workbench 2.

[0041] For example, both the column 11 and the connecting rod 12 are made of steel pipe, the pad 13 is made of steel plate, the connecting rod 12 is welded to the column 11, and the column 11 is welded to the corresponding pad 13.

[0042] Further, see Figure 1 The low-pressure pump maintenance platform also includes multiple anchors, each corresponding to a specific pad 13. The anchors pass through the corresponding pad 13 and are anchored to the ground, thus securing the support 1 to the ground and ensuring its stability. When the low-pressure pump maintenance platform needs to be moved, the anchors are removed from the ground and separated from the pad 13, allowing the support 1 to be easily and quickly separated from the ground.

[0043] For example, the anchor is an anchor bolt.

[0044] Optionally, see Figure 1 A second guardrail 5 is installed on the staircase 4, and the second guardrail 5 is connected to the first guardrail 3. The second guardrail 5 can protect workers as they climb the staircase 4 to prevent them from falling.

[0045] For example, the height of the first guardrail 3 and the second guardrail 5 is both in the range of 900mm to 1100mm, so as to block the center of gravity of the workers and effectively prevent the workers from climbing over the first guardrail 3 and the second guardrail 5. In this embodiment, the height of the first guardrail 3 and the second guardrail 5 is 900mm.

[0046] Optionally, see Figure 1The maintenance workbench 2 is equipped with multiple lifting rings, which are spaced apart around the circumference of the workbench 2. When it is necessary to change the position of the low-pressure pump maintenance platform, the operator can simply hook the hook onto the lifting ring to move the low-pressure pump maintenance platform, which is convenient and quick to operate. The multiple lifting rings can prevent the low-pressure pump maintenance platform from tilting during the movement, ensuring stability and safety during the movement.

[0047] Furthermore, multiple lifting rings are symmetrically arranged on the maintenance workbench 2, which further improves the stability of the low-pressure pump maintenance platform during movement.

[0048] Optionally, see Figure 1 The preset distance range is 100mm to 200mm, which allows the low-pressure pump to pass smoothly through the limiting hole 21 when it is installed on the low-pressure pump maintenance platform, and at the same time, the low-pressure pump will not collide with the hole wall of the limiting hole 21, thus ensuring the safety of the low-pressure pump during installation.

[0049] In this embodiment, the preset distance is 150mm.

[0050] Optionally, see Figure 1 The support frame 1, maintenance workbench 2, first guardrail 3, and stairs 4 are all made of steel, which gives the low-pressure pump maintenance platform a high degree of rigidity and prevents it from easily deforming. This allows the maintenance workbench 2 to support the weight of an adult, ensuring that staff can stand on the maintenance workbench 2 to perform maintenance work on the low-pressure pump.

[0051] In this embodiment, the column 11 is welded to the maintenance workbench 2, the first guardrail 3 is welded to the maintenance workbench 2, and the staircase 4 is welded to the maintenance workbench 2.

[0052] In other embodiments, the column 11 is connected to the maintenance workbench 2, the first guardrail 3 is connected to the maintenance workbench 2, and the staircase 4 is connected to the maintenance workbench 2 by bolts. Bolted connections not only allow for rapid connection between the components of the low-pressure pump maintenance platform, improving assembly efficiency, but also enable detachable connections between the support 1 and the maintenance workbench 2, the first guardrail 3 and the maintenance workbench 2, and the staircase 4 and the maintenance workbench 2. Therefore, when any component of the low-pressure pump maintenance platform is damaged, the faulty component can be replaced individually without replacing the entire platform, thus reducing the operating cost.

[0053] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
