[0027] Please refer to Figure 1-8 As shown, the present utility model provides a top platform of a gas relief tower, including a fixed ring 1 fixedly connected to the outer wall of the top of the gas relief tower. A plurality of groups of triangular braces 2 are annularly distributed on the outside of the fixed ring 1. A connecting ring 23 is fixedly connected to the outer wall of the top of the gas relief tower and below the fixed ring 1. The triangular braces 2 are fixed to the connecting ring 23 through connecting blocks. The upper surface of the triangular brace 2 is fixedly connected to an annular bottom plate 3. The inner side of the annular bottom plate 3 is fixedly connected to a connecting cylinder 34. The upper surface of the connecting cylinder 34 is fixedly connected to an annular workbench plate 4. Two movable plates 5 for installing equipment are movably connected between the annular bottom plate 3 and the annular workbench plate 4. A driving member 6 for driving the movable plate 5 to move is connected to the lower surface of the annular workbench plate 4.

[0028] The present utility model installs two movable plates 5 and a driving member 6 for driving the movable plates 5 to move below the annular workbench plate 4. After the two movable plates 5 are moved out under the action of the driving member 6, they can be used to install equipment and cables, and the annular workbench plate 4 provides a movable space for workers. In the normal working state, the movable plate 5 is located between the annular workbench plate 4 and the annular bottom plate 3, and can effectively protect the equipment and cables on the movable plate 5. When maintenance is required, workers can easily move out the movable plate 5 through the driving member 6 to facilitate the repair and replacement of the equipment.

[0029] Furthermore, a through groove 11 is formed through the fixing ring 1. On the outer side of the upper surface of the fixing ring 1 and on one side of the through groove 11, a slot 12 is formed, and the through groove 11 communicates with the slot 12. At the upper end of the side of the triangular brace 2 close to the fixing ring 1, a placing block 21 is fixedly connected. The placing block 21 is movably connected inside the slot 12. On the side of the placing block 21 away from the triangular brace 2, a clamping block 22 is fixedly connected, and the clamping block 22 is movably connected inside the through groove 11. The clamping block 22 and the fixing ring 1 are fixed by bolts. When assembling the tower top platform, the clamping block 22 can be placed inside the through groove 11 until the lower surface of the placing block 21 fits against the bottom of the slot 12, and then the clamping block 22 and the fixing ring 1 are fixed with bolts. This installation method is convenient, and during installation, there is no need for repeated positioning. Just insert the clamping block 22 into the corresponding through groove 11.

[0030] Furthermore, on both sides of the upper surface of the annular bottom plate 3, main support frames 31 are fixedly connected. On the other two sides of the upper surface of the annular bottom plate 3, side support frames 32 are fixedly connected. And the two groups of main support frames 31 and the two groups of side support frames 32 are all fixedly connected to the lower surface of the annular workbench plate 4. A sliding groove 54 is formed on the upper surface of the movable plate 5, and the side support frame 32 is slidably connected inside the sliding groove 54. The two groups of main support frames 31 and the two groups of side support frames 32 are respectively located at the front, back, left, and right four positions on the upper surface of the annular bottom plate 3, which can effectively and stably support the annular workbench plate 4.

[0031] Furthermore, a surrounding edge 51 is fixedly connected to the outer side of the movable plate 5. On the upper surface of the surrounding edge 51, a number of support rods 52 are fixedly connected at equal intervals. On the upper surface of the support rods 52, a guardrail 521 is fixedly connected. The support rods 52 and the guardrail 521 together form a protective barrier and move together with the movable plate 5, improving the safety of the staff. During the installation process, according to the equipment requirements installed on the movable plate 5, a protective plate can also be installed on the outside of the support rods 52, so that the movable plate 5 and the protective plate form a semi-closed space. When the movable plate 5 is located between the annular workbench plate 4 and the annular bottom plate 3, the protective plate on the outside of the support rods 52 can enclose the space on the movable plate 5, thereby reducing the influence of the external environment on the equipment and cables installed on the movable plate 5.

[0032] Further, the two sets of movable plates 5 are connected by a folding protective member 53. The folding protective member 53 includes a first buckle seat 531 and a second buckle seat 533. The first buckle seat 531 is fixedly connected to one side of a set of support rods 52 on the upper surface of one set of movable plates 5. One side of the first buckle seat 531 is rotatably connected to a first diagonal brace 532. The second buckle seat 533 is fixedly connected to one side of a set of support rods 52 on the upper surface of the other set of movable plates 5. One side of the second buckle seat 533 is rotatably connected to a second diagonal brace 534, and the first diagonal brace 532 and the second diagonal brace 534 are rotatably connected to each other. The folding protective member 53 connects the two sets of movable plates 5. When the movable plates 5 are moved out, it will drive the first diagonal brace 532 and the second diagonal brace 534 to fold and change, ensuring that there is still a protective barrier between the two sets of movable plates 5 after they are moved out, and improving the safety of the staff.

[0033] Further, a plurality of groups of several slide rails 33 arranged in an array form are fixedly connected to the upper surface of the annular bottom plate 3. The lower surface of the movable plate 5 is rotatably connected to a pulley 55 through a connecting seat, and the pulley 55 is slidably connected inside the slide rail 33 at the corresponding position. During the process of moving out the movable plate 5, it will drive the pulley 55 on the lower surface of the movable plate 5 to slide inside the slide rail 33. The setting of the pulley 55 makes it easier and smoother to open the movable plate 5. And the slide rail 33 plays a role of limiting and guiding the pulley 55. The two cooperate with each other, and can indirectly stably support the moving movable plate 5.

[0034] Further, the driving member 6 includes an inverted U-shaped fixed seat 61. The inverted U-shaped fixed seat 61 is fixedly connected to one set of main support frames 31. A double-threaded screw rod 62 is rotatably connected between the openings of the inverted U-shaped fixed seat 61. A first bevel gear 63 is fixedly connected to the middle position on the outer side of the double-threaded screw rod 62. A second bevel gear 64 is meshed with one side of the first bevel gear 63. A control rod 65 is fixedly connected to the inside of the second bevel gear 64. The control rod 65 penetrates the surface of one set of main support frames 31, and the control rod 65 is rotatably connected to the main support frame 31. The control rod 65 penetrates the annular workbench plate 4. A knob 66 is fixedly connected to the upper surface of the control rod 65 and above the annular workbench plate 4. Two nut seats 67 are sleeved on the outer side of the double-threaded screw rod 62, and the two nut seats 67 are respectively fixedly connected to the two sets of movable plates 5. When driving the movable plate 5 to open, only need to manually rotate the knob 66. The knob 66 drives the control rod 65 and the second bevel gear 64 to rotate, and then can drive the first bevel gear 63 and the double-threaded screw rod 62 to rotate. At this time, the two nut seats 67 located on the outer side of the double-threaded screw rod 62 can drive the movable plate 5 to move out.

[0035] Working principle: When maintenance is required for the top of the gas relief tower, maintenance personnel can first climb onto the annular workbench plate 4. If equipment maintenance is needed, the movable plate 5 can be moved out. The specific operation is as follows: Manually rotate the knob 66, and the knob 66 drives the second bevel gear 64 to rotate through the control rod 65, thereby driving the first bevel gear 63 and the double-threaded screw rod 62 to rotate. At this time, the two nut seats 67 on the outside of the double-threaded screw rod 62 slide towards both ends respectively, thereby driving the movable plate 5 to move out.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
