[0002] As one of the most important hydraulic equipment of the ship lock, the anti-arc gate and its hydraulic hoist are responsible for filling and draining water from the water conveyance corridor and isolating the water flow from adjacent lock chambers. Their operating conditions are complex, and they bear huge loads. They are subjected to the impact of high-speed and high-pressure water flow for a long time. At the same time, they are easily affected by underwater foreign objects. Therefore, it is particularly important to maintain and inspect the anti-arc gate and its hydraulic hoist to ensure their good operating condition.

[0003] The anti-arc door oil cylinder is arranged vertically, and two anti-arc door oil cylinder supports stacked on the left and right are provided on the cylinder barrel of the anti-arc door oil cylinder. The bottom of the anti-arc door oil cylinder support is a box-type square steel pipe structure, and the interior of the box-type square steel pipe structure forms a left and right transparent groove.

[0004] The current maintenance and repair of the wellhead valves and their hydraulic hoists present the following challenges: When replacing high-pressure hoses, maintenance personnel typically step on the cylinder base or stand on tiptoe, resulting in a limited working surface and a harsh working environment. The surface of the cylinder support base of the swash gate is irregular, small, and slippery in rainy weather or when greasy. This creates a high risk of accidents when maintenance personnel step on it. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: A reverse arc door maintenance platform, such as Figure 1 and Figure 2 As shown, the working platform includes two slats 1 spaced apart in the front and rear and extending in the left and right directions. A plurality of pedals 2 spaced apart in the left and right directions are connected between the two slats 1. A water-permeable structure that is transparent from top to bottom is formed between adjacent pedals 2. An anti-slip structure is provided on the top of the pedal 2. The anti-slip structure in this embodiment adopts a wavy anti-slip pattern provided on the surface of the pedal 2.

[0026] In order to prevent the operator from tripping due to the toes being accidentally stuck in the gap between two adjacent pedals 2 when walking on the work platform, Figure 1 As shown, in this embodiment, a steel mesh 3 is fixed between adjacent pedals 2 , and the top of the steel mesh 3 is flush with the top of the pedal 2 .

[0027] In order to further improve the operator's physical stability during operation, such as Figure 1As shown, two foot buckles 12 are fixedly provided on the top of the working platform and are spaced apart from each other. The foot buckles 12 are inverted U-shaped rod structures.

[0028] Two outer poles 8 spaced apart are fixedly provided on the left side of the bottom of the working platform. A second cross bar 11 is fixed on the outer pole 8. The second cross bar 11 extends to the right of the outer pole 8. Figure 2 As shown, the second cross bar 11 is used to support the top of the reverse arc door cylinder support base 14.

[0029] The lower end of the outer rod 8 is fixed with a first cross bar 9, the first cross bar 9 and the second cross bar 11 are parallel to each other, and the first cross bar 9 is located directly below the second cross bar 11. Figure 2 As shown, the first cross bar 9 is used to be inserted into the through groove of the reverse arc door cylinder support base 14.

[0030] In order to further improve the stabilizing effect of the first cross bar 9 and the anti-arc door cylinder support base 14 on the working platform, Figure 1 and Figure 2 As shown, the bottom of the first cross bar 9 rests on the bottom wall of the through groove of the reverse arc door cylinder support base 14, and the front and rear outer first cross bars 9 rest on the front and rear side walls of the through groove of the reverse arc door cylinder support base 14.

[0031] In order to reduce the force on the outer pole 8 in supporting the working platform, Figure 1 As shown, an inner vertical rod 10 extending upward is fixedly provided at the right end of the second cross bar 11, and the upper end of the inner vertical rod 10 is fixedly connected to the bottom of the working platform.

[0032] The right side of the working platform is fixedly connected with a hoop structure, which is used to be detachably sleeved on the cylinder barrel of the anti-arc door cylinder 13. Figure 1 and Figure 2 As shown, the clamp structure includes a first arc-shaped gusset plate 5 with a right opening and a second arc-shaped gusset plate 6 with a left opening. The left side of the first arc-shaped gusset plate 5 is fixedly connected with a connecting rod 4 extending to the left. The left end of the connecting rod 4 is fixedly connected to the working platform. The joints of the first arc-shaped gusset plate 5 and the second arc-shaped gusset plate 6 are fixed with connecting plates 7 with screw holes. The two connected connecting plates 7 are fixedly connected by bolts passing through the screw holes.

[0033] Working principle: When inspecting the oil cylinder of the anti-arc door, Figure 2 As shown, first, the two first crossbars 9 are inserted into the through slots of the anti-arc door oil cylinder support base 14, so that the second crossbar 11 is supported on the top of the anti-arc door oil cylinder support base 14. The first crossbars 9, the outer poles 8, the second crossbar 11 and the anti-arc door oil cylinder support base 14 form a snap connection, which can effectively improve the stability of the maintenance platform during maintenance and construction. Finally, the working platform is fixed to the cylinder barrel of the anti-arc door oil cylinder 13 using a clamp structure.

[0034] The work platform is equipped with a permeable structure and an anti-slip structure, which makes the work platform anti-slip and self-draining. In addition, the work platform is a hollow structure, which makes the overall weight of the work platform lighter, making it easier to install, transport and move the entire equipment.

[0035] When the operator is working on the working platform, the sole of his foot can be inserted into the sole buckle 12 to limit the foot and prevent the foot from sliding sideways.

[0036] After the inspection is completed, the hoop structure is removed from the cylinder barrel of the reverse arc door oil cylinder 13, and the inspection platform can be quickly removed from the reverse arc door oil cylinder supporting base 14.

[0037] Example 2: A reverse arc door maintenance platform. This example differs from Example 1 in that the platform utilizes a serrated steel grating structure (the structure of serrated steel grating is prior art and will not be described in detail here). This serrated steel grating structure utilizes toothed flat steel with uneven tooth marks on one side, which effectively improves anti-slip performance. The remaining structure is the same as Example 1.

[0038] Example 3: A reverse arc door maintenance platform. This example differs from Example 1 in that three first crossbars 9, three outer vertical bars 8, three second crossbars 11, and three inner vertical bars 10 are provided. Other structures are the same as those in Example 1.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
