Description

Technical Field

[0001] The utility model relates to the field of pump station maintenance platforms, in particular to a pump station water pump unit lower cylinder maintenance platform. Background Art

[0002] The main function of the lower cylinder of the water pump unit is to convert the hydraulic energy of the main engine into mechanical energy, and drive the rotor to move, so as to achieve the purpose of driving the water pump to rotate. Some lower cylinders are installed vertically between the water pump and the lower cylinder is located above the water pump. Therefore, there is a certain distance between the lower cylinder and the bottom of the foundation pit. In the pump station, the distance between the lower cylinder and the bottom of the foundation pit is large. When inspecting the lower cylinder, maintenance personnel generally build scaffolding to maintain and repair the lower cylinder and its related parts. However, building scaffolding is time-consuming and laborious, not only inefficient but also inconvenient to operate. One of them is that there is no suitable location and space for scaffolding at the bottom of the foundation pit in some cases, so it is more laborious to build; in addition, this is generally a simple bracket structure built on site, which is relatively low in safety, and maintenance personnel are prone to safety accidents during maintenance and repair. Utility Model Content

[0003] At present, the distance between the lower oil cylinder of the water pump unit used in the pump station and the bottom of the foundation pit is large, which makes it impossible for maintenance personnel to directly maintain and repair the inside of the lower oil cylinder and its related parts. It is necessary to build a scaffolding, which is a simple bracket built on site. Therefore, the safety is low and safety accidents are prone to occur. In addition, building a scaffolding is time-consuming and labor-intensive, which is not only inefficient but also inconvenient to operate. At least one purpose or one aspect of the present application can solve the above problems. A pump station water pump unit lower oil cylinder maintenance platform is specifically designed, which can be disassembled after use or used for a long time and multiple times without disassembly. The specific technical solution adopted is:

[0004] A pump station water pump unit lower cylinder maintenance platform, including a support platform, the support platform center is provided with a through hole for the lower cylinder piston rod to pass through, the outer edge of the support platform is provided with a plurality of suspension rods along its periphery, the suspension rods are arranged perpendicular to the support platform, the suspension rods are fixed at one end away from the support platform, the support platform is provided with a continuous through hole toward its edge, the continuous through hole is used for the lower cylinder piston rod to pass through.

[0005] Preferably, the support platform is circular and includes an inner fixing ring and an outer fixing ring. The through hole is formed by the inner fixing ring. A plurality of connecting strips are radially arranged between the inner fixing ring and the outer fixing ring. The plurality of connecting strips are arranged at intervals along the circumference of the inner fixing ring and the outer fixing ring.

[0006] Preferably, the continuous through opening extends from the inner fixing ring to the outer fixing ring to form a fan-shaped continuous through opening.

[0007] Preferably, the two connecting strips correspond to two radii of the fan-shaped continuous through-opening, and a suspension rod is provided at the intersection of the two radii and the outer fixing ring.

[0008] Preferably, a connecting rod is detachably connected between two radii corresponding to the continuous through-ports, and the connecting rod is used for setting up the ladder.

[0009] Preferably, both ends of the connecting rod have a 90° downward corner, and the side edges of the connecting strips on both sides of the fan-shaped continuous through opening corresponding to the connecting strips have slots, and the connecting rod can be stuck in the slots.

[0010] Preferably, the suspension rod, the inner fixing ring, the outer fixing ring and the connecting strip are made of stainless steel.

[0022] like Figure 1-2 As shown, a maintenance platform for the lower cylinder of a water pump unit in a pump station is arranged between the water pump and the lower cylinder of the water pump unit, and is mainly used in the case where the lower cylinder is arranged vertically and is located above the water pump. The maintenance platform mainly includes a support platform 1, and a through hole 2 is provided at the center of the support platform 1. The through hole 2 is used for the lower cylinder piston rod 12 to pass through. Therefore, the arrangement of the support platform 1 will not affect the normal operation of the water pump unit. The outer edge of the support platform 1 is provided with a plurality of suspension rods 7 along its periphery. The suspension rods 7 are arranged perpendicular to the support platform 1, and the end of the suspension rod 7 away from the support platform 1 is a fixed end. In the present application, the upper end of the suspension rod 7 is fixed on a concrete pile 10 for fixing the lower cylinder. The specific fixing method can be connection with expansion screws, or structural members can be pre-embedded in the concrete pile 10, and then the upper end of the suspension rod 7 is hung on the pre-embedded structural member. In addition, during installation, in order to allow the piston rod 12 of the lower oil cylinder to enter the through hole 2 at the center of the support platform 1, a continuous through hole 3 is provided on the support platform 1 from the through hole 2 to its edge. The continuous through hole 3 as a whole can be formed along a straight line trajectory, a wavy line trajectory, or a straight line with multiple corners 5, etc., as long as the continuous through hole 3 passes through the through hole 2 and the outer edge of the support platform 1.

[0023] Furthermore, the support platform 1 is circular and includes an inner fixing ring 101 and an outer fixing ring 102. The through hole 2 is formed by the inner fixing ring 101. A plurality of connecting strips 103 are radially arranged between the inner fixing ring 101 and the outer fixing ring 102. The plurality of connecting strips 103 are arranged at intervals along the circumference of the inner fixing ring 101 and the outer fixing ring 102. The support platform 1 of this structure is light in weight, can meet the requirements, and is easier to install.

[0024] Of course, in other embodiments, the support platform 1 may also be in other shapes, such as square, rectangular, oval, etc.

[0025] Furthermore, the continuous through opening 3 extends from the inner fixing ring 101 to the outer fixing ring 102 to form a fan-shaped continuous through opening 3. Under the premise of the circular support platform 1, the fan-shaped continuous through opening 3 is convenient to open.

[0026] Furthermore, two of the connecting strips 103 correspond to two radii of the fan-shaped continuous through-opening 3, and a suspension rod 7 is provided at the intersection of the two radii and the outer fixing ring 102. Setting two of the suspension rods 7 at the edge of the fan-shaped continuous through-opening 3 can improve the structural strength of the support platform 1 at this location and avoid deformation and other problems when this location is subjected to force.

[0027] Furthermore, in order to facilitate maintenance personnel to enter the support platform 1, a connecting rod 6 is detachably connected between the two radii corresponding to the continuous through-port 3, and the connecting rod 6 is used to set up a ladder 11, and maintenance personnel enter the support platform 1 via the ladder 11.

[0028] Furthermore, the detachable connection method of the above-mentioned connecting rod 6 is specifically that a 90° downward corner 5 is set at both ends of the connecting rod 6, and the fan-shaped continuous through-opening 3 has a card slot 4 on the side of the connecting strip 103 on both sides, and the connecting rod 6 can be stuck in the card slot 4. This connection method is convenient and quick to disassemble and install. When disassembling the connecting rod 6, you only need to take out the connecting rod 6 upwards, and the corner 5 of the connecting rod 6 can be removed from the card slot 4.

[0029] Furthermore, the suspension rod 7, the inner fixing ring 101, the outer fixing ring 102 and the connecting strip 103 are made of stainless steel, which has the advantages of strong durability, high corrosion resistance and high strength.

[0030] Furthermore, the above-mentioned suspension rod 7 has a threaded section 8, which is arranged near the lower end of the suspension rod 7. The outer edge of the support platform 1 is provided with multiple threaded holes at intervals along its circumference. The suspension rod 7 is threaded through the threaded holes and connected to the nut 9. The height of the support platform 1 can be adjusted through the above-mentioned connection method to facilitate maintenance and repair personnel to maintain or repair different positions of the lower cylinder.

[0031] Furthermore, in order to improve the connection strength between the suspension rod 7 and the support platform 1 , at least two nuts 9 are provided, and the two nuts 9 are threadedly connected to the suspension rod 7 at the same time.

[0032] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
