Description

Technical Field

[0001] This utility model relates to the field of maintenance, specifically to a maintenance support platform. Background Technology

[0002] As a critical component of the thermal system, abnormal water levels in the deaerator can lead to feedwater pump cavitation, steam pressure fluctuations, or even system failure. Therefore, deaerators must be equipped with level gauges to monitor and control the water tank level, ensuring safe and stable operation of the equipment.

[0003] Because the level gauge probe is quite high and the level gauge display panel is located at the top of the probe, scaffolding needs to be erected to observe and troubleshoot level gauge malfunctions, and it is difficult for personnel to operate the control panel.

[0004] The current solution is to open an observation port on the foundation platform directly above the level gauge, and fix a transparent plate inside the observation port. Personnel can stand on the platform and observe the level gauge display panel through the transparent plate. However, since people often walk on the foundation platform, the mud under their feet can easily blur the transparent plate, making it difficult to observe. In addition, scaffolding still needs to be erected during maintenance, which takes a long time and affects maintenance efficiency. Utility Model Content

[0015] like Figures 1 to 17 As shown, a maintenance support platform includes a base platform 1. The support plate 1.1 of the base platform 1 is provided with an observation port 1.2. In order to facilitate personnel to quickly maintain the level gauge below the base platform 1, a rectangular manhole 1.3 and two rectangular slots 1.4 are also provided on the support plate 1.1. The two rectangular slots 1.4 are symmetrically distributed on the side away from the observation port 1.2. A folding support frame 2 is installed on the rectangular manhole 1.3 and the two rectangular slots 1.4. The folding support frame 2 has two functions: first, it allows personnel to stand on the folding support frame 2 to facilitate personnel maintenance work; second, the folding support frame 2 can close the exposed rectangular manhole 1.3 and the two rectangular slots 1.4 to prevent personnel from falling in. The folding support frame 2 specifically includes a positioning plate 2.1, a sliding plate 2.2, a cover plate 2.3, and a T-shaped iron hook 2.4; Wherein, the positioning plate 2.1 comprises a n-shaped plate 2.12, transverse clamping blocks 2.13, longitudinal clamping blocks 2.14 and a Japanese-shaped plate 2.15; the width of the n-shaped plate 2.12 is equal to the width of the rectangular manhole 1.3, and the length of the n-shaped plate 2.12 is greater than the length of the rectangular manhole 1.3, so that the n-shaped plate 2.12 can be lapped above the rectangular manhole 1.3 to achieve sealing. Two transverse clamping blocks 2.13 are symmetrically fixed on one side of the lower surface of the n-shaped plate 2.12 close to the opening, and two longitudinal clamping blocks 2.14 are symmetrically fixed on one side of the lower surface of the n-shaped plate 2.12 away from the opening. The longitudinal clamping blocks 2.14 have an L-shaped structure, and both the transverse clamping blocks 2.13 and the longitudinal clamping blocks 2.14 can be inserted into the rectangular slots 1.4, so that the fastened positioning plate 2.1 does not move randomly. The Japanese-shaped plate 2.15 is fixed on the lower surface of the n-shaped plate 2.12 and between the two longitudinal clamping blocks 2.14, and a gap between the Japanese-shaped plate 2.15 and the n-shaped plate 2.12 forms a limit sliding chute 2.11, so that the sliding plate 2.2 and the limit blocks 2.21 can slide in the limit sliding chute 2.11.

[0016] Wherein, the sliding plate 2.2 has a Japanese-shaped structure, limit blocks 2.21 are fixed on both sides of one end of the sliding plate 2.2, the sliding plate 2.2 and the limit blocks 2.21 are slidably arranged in the limit sliding chute 2.11. When the longitudinal clamping blocks 2.14 are inserted into the rectangular slots 1.4, the folding support frame 2 is arranged longitudinally. Since both the Japanese-shaped plate 2.15 and the sliding plate 2.2 have a Japanese-shaped structure, a ladder is formed by sliding the sliding plate 2.2 downward, which is convenient for personnel to step on. Meanwhile, two armrests 2.23 are symmetrically fixed on both sides of the upper surface of the sliding plate 2.2, which is convenient for personnel to grip during operation.

[0017] In order to facilitate better safe operation and safety protection for personnel, a cover plate 2.3 is hinged on the upper surface of the other end of the sliding plate 2.2, and the cover plate 2.3 can be turned over.

[0018] Two first movable grooves 2.22 are symmetrically formed on both sides of the middle part of the sliding plate 2.2, T-shaped hooks 2.4 are movably penetrated in both of the two first movable grooves 2.22, the T-shaped end of the T-shaped hook 2.4 is hinged to the middle part of the cover plate 2.3, and the hooked end of the T-shaped hook 2.4 moves on the side of the sliding plate 2.2 facing away from the cover plate 2.3. Two second movable grooves 2.151 are symmetrically formed on both sides of the middle part of the Japanese-shaped plate 2.15, and the two second movable grooves 2.151 respectively correspond to the two first movable grooves 2.22, so that the cover plate 2.3 can fit the surface of the sliding plate 2.2 after being turned over.

[0019] When the transverse clamping blocks 2.13 are inserted into the rectangular slots 1.4, the folding support frame 2 is arranged transversely, and the cover plate 2.3 can cover the exposed holes on the sliding plate 2.2 by turning over.

[0020] When the longitudinal locking block 2.14 is inserted into the rectangular slot 1.4, the folding support frame 2 is in a longitudinal position. By sliding the slide plate 2.2 downward and flipping the cover plate 2.3, when one end of the T-shaped iron hook 2.4 abuts against the side of the slide plate 2.2 away from the cover plate 2.3 and remains stationary, the cover plate 2.3 and the slide plate 2.2 are perpendicular to each other, and the cover plate 2.3 is relatively horizontal, which makes it easier for employees to stand.

[0021] A clamping handle 2.5 is rotatably provided on the cover plate 2.3. The clamping plate 2.51 of the clamping handle 2.5 is movably placed on the lower surface of the support plate 1.1. By rotating the clamping handle 2.5, the position of the clamping plate 2.51 is controlled, so that the cover plate 2.3 can be opened or the support frame 2 can be removed from the rectangular manhole 1.3.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
