Description

Technical Field

[0001] This invention belongs to the field of integrated pumping stations, specifically, it relates to an integrated pumping station maintenance platform. Background Technology

[0002] Existing integrated pumping stations are turnkey pumping units that lift sewage, rainwater, drinking water, and wastewater. They are manufactured and assembled in a factory and then transported to the site for installation. The subsequent management and maintenance of these prefabricated pumping stations require specialized personnel. Due to the large and deep cylinder, management and maintenance personnel must descend into the cylinder to perform their work.

[0003] Chinese Patent Publication No. CN216713766U discloses an integrated pump station maintenance platform with protective functions, relating to the field of maintenance platform technology. This integrated pump station maintenance platform with protective functions includes a pump station housing, within which a fixed grid is installed. A support beam is fixedly connected to the lower surface of the fixed grid. A mounting shell is fixedly connected to the inner wall of the pump station housing. The mounting shell has a contact block that contacts the lower surface of the support beam. A control push rod with its lower end penetrating into the mounting shell is fixedly connected to the lower surface of the contact block. This integrated pump station maintenance platform with protective functions prevents the fixed grid from tilting downwards due to the weld joints between the support beam and the pump station housing detaching, and also prevents the fixed grid from breaking due to excessive downward tilting.

[0004] The above-mentioned integrated pump station maintenance platform reduces the risk of the support plate breaking due to excessive impact by setting a contact plate under the fixed grid. However, when maintenance personnel carry large or heavy maintenance tools into the pump station cylinder, there is a risk that the maintenance tools may fall and cause the maintenance personnel to fall as well, resulting in danger.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an integrated pump station maintenance platform.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] An integrated pump station maintenance platform includes a maintenance platform body installed inside the pump station body. The maintenance platform body includes: a fixing plate; an inlet / outlet frame is installed on the maintenance platform body; a cover is rotatably fitted on the inlet / outlet frame; a climbing component is installed at the bottom of the maintenance platform body; and a placement component is installed on the fixing plate.

[0009] The climbing assembly includes a lifting bar that slides on the maintenance platform body, a first connecting frame that rotates on the bottom of the fixed plate, a second connecting frame that rotates on the first connecting frame, and a stair frame that rotates on the maintenance platform body. The lifting bar is engaged with the cover, the lifting bar is engaged with the second connecting frame, the first connecting frame is engaged with the stair frame, and the stair frame has a first step and multiple second steps that rotate on it.

[0010] Optionally, a support rod is provided between the inlet / outlet frame and the cover. A gear is installed on one side of the cover, and a toothed block is installed on the lifting bar. The gear and the toothed block mesh with each other. A first slider is installed at the bottom of the lifting bar. A first groove is opened on one side of the fixed plate. The first slider slides in the first groove. First connecting posts are installed on opposite sides of the first slider. First connecting slots are opened on opposite sides of the second connecting frame. The first connecting post rotatably engages in one of the first connecting slots. A first connecting rod and a second connecting rod are respectively installed on the first connecting frame. The second connecting rod rotatably engages in the other first connecting slot. A second connecting slot is opened at the bottom of the fixed plate. The first connecting rod is rotatably engaged in the second connecting groove. A third connecting groove is provided on one side of the first connecting frame, and a third connecting rod is rotatably engaged in the third connecting groove. Second sliders are installed on both opposite sides of the third connecting rod, and second sliding grooves are provided on both opposite sides of the stair frame. The second sliders are slidably engaged in the second sliding grooves. By providing a support rod between the inlet / outlet frame and the cover, the support rod provides support and fixation when maintenance personnel open the cover, reducing the instability of the fixing plate, the first connecting frame, and the stair frame caused by the cover rotating. This also reduces the inconvenience of the cover closing when maintenance personnel are performing maintenance under the maintenance platform.

[0011] Optionally, a fourth connecting groove is provided on both inner walls of the entrance / exit frame; a second connecting column is installed on each opposite side of the stair frame, the second connecting column being rotatably fitted into the fourth connecting groove; a fifth connecting groove is provided on both inner walls of the stair frame; a third connecting column and a fourth connecting column are installed on each opposite side of the first tread and multiple second treads, the third connecting column being rotatably fitted into the fifth connecting groove; a connecting plate and a handrail frame are respectively provided on both sides of the first tread and multiple second treads; multiple sixth connecting grooves are provided on the connecting plate; a fourth connecting rod is installed on the second tread, the fourth connecting rod being rotatably fitted into the sixth connecting groove; multiple seventh connecting grooves are provided on one side of the handrail frames on both sides, the fourth connecting column being rotatably fitted into the seventh connecting groove; a third sliding groove is provided on each opposite side of the first tread, the third sliding groove being slidably fitted into the third sliding groove. The third slider is equipped with a fifth connecting rod. A groove is provided on one side of the fixed plate, and the fifth connecting rod slides in the groove. A first spring is installed between the third slider and the inner wall of the third slide groove. By setting connecting plates and handrails on both sides of the first step and multiple second steps respectively, when the stair frame rotates and opens in the fourth connecting groove at the entrance frame, it simultaneously drives the fifth connecting rod on the first step to slide downward in the groove, so that the first step is parallel to the maintenance platform body and is in a horizontal state. At the same time, the connecting plates drive the multiple second steps to be in a horizontal state with the first step, thus forming a staircase that makes it easy for maintenance personnel to step on and climb up and down for maintenance work, reducing the danger of maintenance personnel jumping down. At the same time, the handrails stand upright on the first step and multiple second steps to provide protection.

[0012] Optionally, the placement assembly includes a placement plate slidably fitted onto a fixed plate, multiple slots on one side of the fixed plate, a locking block slidably fitted onto the placement plate, and an L-shaped frame rotatably fitted onto the placement plate. The locking block engages within the slots. A first brake block is mounted on one side of the fixed plate, and a second brake block is mounted on one side of the L-shaped frame, with the second brake block abutting against the first brake block. A fixed frame is mounted on the placement plate, with a limit groove within the frame. The locking block slidably fits within the limit groove. A T-shaped pull rod is mounted on one side of the locking block, and a second spring is fitted onto the T-shaped pull rod, located within the limit groove. A T-shaped groove is formed on one side of the L-shaped frame, with the T-shaped pull rod located within the T-shaped groove. A through groove is formed on one side of the L-shaped frame, and a fixed shaft is mounted on the placement plate, with the through groove rotatably fitted onto the fixed shaft. By having a placement plate slidably fitted onto one side of the fixed plate, maintenance tools used by maintenance personnel can be placed on the placement plate. Placed on top, the locking block is engaged in the slot of the fixed plate by the force of the second spring, ensuring the stability of the placement plate. When the maintenance personnel move downwards, they pull one end of the L-shaped frame, causing the L-shaped frame to rotate on the fixed shaft, thereby pulling the T-shaped pull rod and causing the locking block to disengage from the slot. At the same time, the second brake block abuts against the first brake block to provide a braking effect, reducing the situation where the placement plate falls too quickly on the lifting bar. The speed at which the placement plate descends can be determined by the pulling force of the maintenance personnel, making it convenient for maintenance personnel to carry heavy maintenance tools into the pump station body for maintenance. After maintenance is completed, the heavy maintenance tools are placed on the placement plate, and the locking blocks are positioned in different slots when the plate is lifted upwards. The inclined side of the locking block is set upwards, so that when the placement plate is moved upwards, it is locked after being released to prevent it from falling, reducing the burden on maintenance personnel carrying heavy maintenance tools.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. When maintenance personnel are performing maintenance on the integrated pump station maintenance platform, they can open the cover of the inlet / outlet frame. The rotating cover causes the lifting bar to move downwards. The downward-moving lifting bar, through the second connecting frame, causes the first connecting frame to rotate downwards, making it horizontal with the maintenance platform body. This causes the stair frame to open, stabilizing the fixed plate, the first connecting frame, and the stair frame. This allows maintenance personnel to smoothly move downwards by stepping on the first and second steps of the stair frame. Maintenance tools carried by the personnel can be placed in the placement component on the fixed plate. As the personnel move downwards, the tools move downwards with them, reducing the burden on the personnel and minimizing the risk of them falling while carrying heavy tools.

[0015] 2. This integrated pump station maintenance platform features a sliding mounting plate on one side of a fixed plate, allowing maintenance personnel to place their tools on it. A locking block, secured by a second spring, engages with a slot in the fixed plate, ensuring stability. As maintenance personnel move downwards, pulling one end of an L-shaped frame rotates it on a fixed shaft, pulling a T-shaped rod and disengaging the locking block from its slot. Simultaneously, a second brake block engages with the first brake block, providing braking and reducing the rapid descent of the mounting plate on the lifting bar. The descent speed of the mounting plate is determined by the pulling force of the personnel, facilitating the entry of heavier tools into the pump station for maintenance. After maintenance, the heavier tools are placed on the mounting plate, and the platform is lifted upwards. The locking blocks, with their upward-facing edges, secure the platform when it is released, preventing it from falling and reducing the burden on maintenance personnel carrying heavy tools.

[0029] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0030] The invention will now be described in further detail with reference to the accompanying drawings.

[0031] Please see Figure 1-9 As shown, this embodiment provides an integrated pump station maintenance platform, including a maintenance platform body 3 installed inside the pump station body 1. The maintenance platform body 3 includes: a fixing plate 2, an inlet / outlet frame 301 installed on the maintenance platform body 3, a cover 303 rotatably fitted on the inlet / outlet frame 301, a climbing component installed at the bottom of the maintenance platform body 3, and a placement component installed on the fixing plate 2.

[0032] The climbing assembly includes a lifting bar 4 that slides on the maintenance platform body 3, a first connecting frame 5 that rotates on the bottom of the fixed plate 2, a second connecting frame 6 that rotates on the first connecting frame 5, and a stair frame 7 that rotates on the maintenance platform body 3. The lifting bar 4 is engaged with the cover 303, the lifting bar 4 is engaged with the second connecting frame 6, the first connecting frame 5 is engaged with the stair frame 7, and the stair frame 7 is rotatably engaged with a first step 8 and multiple second steps 9.

[0033] One application of this embodiment is as follows: Figure 2 As shown: When maintenance personnel are performing maintenance on the maintenance platform body 3 inside the pump station body 1, they open the cover 303 of the inlet / outlet frame 301. The rotating cover 303 drives the lifting bar 4 to move downward. The downward-moving lifting bar 4 drives the first connecting frame 5 to rotate downward through the second connecting frame 6, making it horizontal with the maintenance platform body 3. This causes the stair frame 7 to be in an open state, making the fixed plate 2, the first connecting frame 5, and the stair frame 7 stable. This allows maintenance personnel to step on the first step 8 and the second step 9 of the stair frame 7 and move downward smoothly. The maintenance tools carried by the maintenance personnel can be placed in the placement component of the fixed plate 2. As the maintenance personnel move downward, the tools can be moved downward, reducing the burden on the maintenance personnel and reducing the possibility of the maintenance personnel falling while carrying heavy maintenance tools.

[0034] In this embodiment, a support rod 302 is provided between the inlet / outlet frame 301 and the cover 303. A gear 304 is installed on one side of the cover 303, and a toothed block 401 is installed on the lifting bar 4. The gear 304 meshes with the toothed block 401. A first slider 402 is installed at the bottom of the lifting bar 4. A first groove 202 is opened on one side of the fixing plate 2. The first slider 402 slides within the first groove 202. First connecting posts 403 are installed on opposite sides of the first slider 402. First connecting slots 601 are opened on opposite sides of the second connecting frame 6. The first connecting post 403 rotatably engages within one of the first connecting slots 601. A first connecting rod 501 and a second connecting rod 502 are respectively installed on the first connecting frame 5. The second connecting rod 502 rotatably engages within the other first connecting slot 601. A first connecting rod 501 and a second connecting rod 502 are respectively installed on the first connecting frame 5. The second connecting rod 502 rotatably engages within the other first connecting slot 601. A first connecting rod 501 is opened at the bottom of the fixing plate 2. A second connecting groove 203 is provided, and a first connecting rod 501 is rotatably engaged within the second connecting groove 203. A third connecting groove 503 is provided on one side of the first connecting frame 5, and a third connecting rod 504 is rotatably engaged within the third connecting groove 503. Second sliders 505 are installed on both opposite sides of the third connecting rod 504. Second sliding grooves 701 are provided on both opposite sides of the stair frame 7, and the second sliders 505 are slidably engaged within the second sliding grooves 701. A support rod 302 is provided between the inlet / outlet frame 301 and the cover 303. When maintenance personnel open the cover 303, the support rod 302 provides support and fixation, reducing the instability of the fixed plate 2, the first connecting frame 5, and the stair frame 7 caused by the rotation of the cover 303. This also reduces the inconvenience of the cover 303 being closed when maintenance personnel are performing maintenance below the maintenance platform body 3. Figure 9 As shown: When the maintenance personnel close the cover 303 after maintenance, the lifting bar 4 moves upward. The upward-moving lifting bar 4 drives the first connecting frame 5 to rotate upward through the second connecting frame 6, thereby causing the stair frame 7 to be in a retracted state, so that it can be stored on one side of the fixed plate 2.

[0035] In this embodiment, the inner walls of the entrance / exit frame 301 are provided with fourth connecting grooves 305. Second connecting posts 702 are installed on opposite sides of the stair frame 7, and the second connecting posts 702 are rotatably fitted within the fourth connecting grooves 305. Fifth connecting grooves 703 are provided on the inner walls of both sides of the stair frame 7. Third connecting posts 14 and fourth connecting posts 13 are installed on opposite sides of the first tread 8 and multiple second treads 9, and the third connecting posts 14 are rotatably fitted within the fifth connecting grooves 703. Connecting plates 10 and handrail frames 11 are respectively provided on both sides of the first tread 8 and multiple second treads 9. Multiple sixth connecting grooves 16 are provided on the connecting plates 10. Fourth connecting rods 15 are installed on the second treads 9, and the fourth connecting rods 15 are rotatably fitted within the sixth connecting grooves 16. Multiple seventh connecting grooves 12 are provided on one side of the handrail frames 11, and the fourth connecting posts 13 are rotatably fitted within the seventh connecting grooves 12. Third sliding grooves 17 are provided on opposite sides of the first tread 8, allowing sliding within the third sliding grooves 17. The staircase is equipped with a third slider 18, on which a fifth connecting rod 20 is mounted. A groove 201 is provided on one side of the fixing plate 2, and the fifth connecting rod 20 slides within the groove 201. A first spring 19 is installed between the third slider 18 and the inner wall of the third slide groove 17. A connecting plate 10 and a handrail 11 are respectively provided on both sides of the first step 8 and the multiple second steps 9. When the staircase frame 7 is opened by rotating in the fourth connecting groove 305 of the entrance frame 301, the fifth connecting rod 20 on the first step 8 slides downward in the groove 201, making the first step 8 parallel to the maintenance platform body 3 and horizontal. At the same time, the connecting plate 10 drives the multiple second steps 9 to be horizontal with the first step 8, thus forming a staircase that is convenient for maintenance personnel to step on and climb up and down for maintenance work, reducing the risk of danger if maintenance personnel jump down. Meanwhile, the handrail 11 stands upright on the first step 8 and the multiple second steps 9 to provide protection.

[0036] The placement assembly of this embodiment includes a placement plate 22 that slides on a fixed plate 2, multiple slots 25 formed on one side of the fixed plate 2, a locking block 26 that slides on the placement plate 22, and an L-shaped frame 23 that rotates on the placement plate 22. The locking block 26 engages with the slots 25. A first brake block 24 is installed on one side of the fixed plate 2, and a second brake block 33 is installed on one side of the L-shaped frame 23. The second brake block 33 abuts against the first brake block 24. A fixing frame 21 is installed on the placement plate 22. A limiting groove 29 is provided, and a locking block 26 slides within the limiting groove 29. A T-shaped pull rod 31 is installed on one side of the locking block 26, and a second spring 30 is sleeved on the T-shaped pull rod 31, located within the limiting groove 29. A T-shaped groove 32 is provided on one side of the L-shaped frame 23, and the T-shaped pull rod 31 is located within the T-shaped groove 32. A through groove 27 is provided on one side of the L-shaped frame 23, and a fixed shaft 28 is installed on the placement plate 22. The through groove 27 rotatably engages with the fixed shaft 28. The placement plate 22 slides within the fixed plate 23. Plate 22 allows maintenance tools to be placed on it. The locking block 26 is engaged in the slot 25 of the fixed plate 2 by the force of the second spring 30, ensuring the stability of the plate 22. When maintenance personnel move downwards, pulling one end of the L-shaped frame 23 causes it to rotate on the fixed shaft 28, thereby pulling the T-shaped rod 31 and disengaging the locking block 26 from the slot 25. Simultaneously, the second brake block 33 abuts against the first brake block 24, providing a braking effect and reducing the impact of the plate 22 falling up and down the lifting bar 4. In cases where the speed is too fast, the descent speed of the placement plate 22 can be determined by the pulling force of the maintenance personnel. This facilitates the maintenance personnel carrying heavier maintenance tools into the pump station body 1 for maintenance. After maintenance is completed, the heavier maintenance tools are placed on the placement plate 22 and lifted upwards. The locking blocks 26 are located in different slots 25. The inclined side of the locking blocks 26 is set upwards, so that when the placement plate 22 is moved upwards, it is locked after being released and will not fall, thus reducing the burden on the maintenance personnel carrying heavier maintenance tools.
