Description

Technical Field

[0001] This utility model relates to the technical field of acid tank opening anti-fall device, specifically a novel acid tank opening anti-fall device. Background Technology

[0002] With the upgrading of industry safety standards and changes in the storage media and scale of acid tanks, traditional protection solutions are no longer sufficient to meet the comprehensive requirements of modern chemical production for safety, efficiency, and corrosion resistance. This has driven the development of new equipment. As core equipment for storing corrosive media such as sulfuric acid, hydrochloric acid, and nitric acid in industries such as chemical, metallurgical, and pharmaceutical, acid tanks have openings (manholes, inspection ports) that are the only passage for personnel to enter and exit for inspection and equipment maintenance. However, they are also high-risk areas for safety accidents, mainly due to several core pain points: High risk of falls from height: Acid tanks are mostly vertical storage tanks, generally over 2 meters high, and their openings are typical "edge-prone openings." According to the "Safety Specifications for High-Altitude Operations in Chemical Production Units" (AQ3025-2008)... Such operations must take fall protection measures, but traditional protection methods (such as temporary fences and planks) have problems with untimely protection and poor reliability. Fall accidents can easily occur due to human negligence or failure of protection, with serious consequences. There is a contradiction between operation and protection in traditional equipment. The traditional protection of acid tank openings mainly relies on "independent cover plates + simple locks", which has obvious design flaws: cumbersome operation: the cover plates are mostly made of heavy carbon steel or cast iron, requiring 2-3 people to carry and open them, resulting in low maintenance efficiency and easy collisions during transportation that can cause acid spillage. Discontinuous protection: after the cover plate is opened, the opening is completely exposed, requiring additional temporary protective facilities (such as safety nets), creating a gap of "loss of protection upon opening", increasing the risk of operation.

[0003] However, existing new acid tank opening anti-fall devices have the following disadvantages: (1) At present, during the use of this device, most of its cover plates need to be manually moved by staff to complete the opening operation. This traditional manual moving method not only increases the labor intensity of workers, but also easily leads to operational errors and low efficiency during the moving process. More seriously, since the cover plates are usually heavy and large in size, there are safety hazards such as slipping and pinching during manual moving, which directly affects the safety and efficiency of maintenance work, resulting in low overall work efficiency and may cause accidents. (2) At present, when the device is in use, most of the grids are laid flat at the mouth of the tank. However, different filling ports will have different heights. Laying the grids flat can easily cause some unstable movement during use and also cause a drop. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a novel acid tank opening anti-fall device, which solves the problems mentioned in the background art, such as the need for manual handling of the cover plate by workers and the instability caused by the flat laying of the grating mesh due to its low cost and uneven height.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a novel acid tank opening anti-fall device, comprising an auxiliary opening assembly, the auxiliary opening assembly comprising a hydraulic rod, a first connecting block, a first connecting rod, a second connecting rod, a second connecting block, a third connecting rod, a third connecting block, a fourth connecting rod, a fifth connecting rod, a fourth connecting block, and a cover plate, wherein one end of the hydraulic rod is fixedly connected to the first connecting block, one side of the first connecting block is rotatably connected to the first connecting rod, the first connecting rod is rotatably connected to the second connecting rod, and the first connecting rod and the second connecting rod are rotatably connected to the second connecting block via a rotating shaft; The other end of the second link is rotatably connected to a third link, the third link is rotatably connected to a fourth connecting block, one side of the fourth connecting block is rotatably connected to a fifth link, the fifth link is rotatably connected to the fourth link, the fourth link is rotatably connected to the third connecting block via a rotating shaft, and a cover plate is fixedly connected to the bottom of the fourth connecting block.

[0006] Optionally, the other end of the hydraulic rod is rotatably connected to a base plate, the bottom of the base plate is threaded to the ground, and the bottom of the cover plate is rotatably connected to a cover opening.

[0007] Optionally, the cover opening is movably connected to a grid mesh via a spring, and an adjustment component is provided on one side of the grid mesh.

[0008] Optionally, the adjustment assembly includes a first servo motor, a first bevel gear, a second bevel gear, a lead screw, a threaded block, an adjustment plate, and a stabilizing plate. The output shaft end of the first servo motor is splinedly connected to the first bevel gear, and the first bevel gear meshes with the second bevel gear.

[0009] Optionally, a lead screw is fixedly connected to the bottom of the second bevel gear, a threaded block is threadedly connected to the lead screw, and a stabilizing plate is fixedly connected to one side of the threaded block.

[0010] Optionally, the stabilizing plate is slidably connected to an adjusting plate, the adjusting plate is fixedly connected to the grid mesh, and a flange is provided at the bottom of the cover, with sealing gaskets provided on the outer and inner surfaces of the flange.

[0011] (III) Beneficial Effects This utility model provides a novel acid tank opening anti-fall device, which has the following beneficial effects: 1. This novel acid tank opening anti-fall device, through the arrangement of hydraulic rods, a first connecting rod, a second connecting rod, and a third connecting rod, enables the entire cover to be opened quickly and mechanically, eliminating the need for extensive manual labor. The hydraulic rod drives the first connecting rod, which in turn drives the connected second connecting rod via a rotating shaft. The second connecting rod drives the third connecting rod, and the third connecting rod, through a fourth connecting block, causes the cover to rotate to one side and open according to the fourth and fifth connecting rods. This not only facilitates opening the tank but also improves the overall safety of the opening process.

[0012] 2. This novel acid tank opening anti-fall device, through the arrangement of a first bevel gear, a second bevel gear, a lead screw, and a threaded block, enables the overall device to stably position the grid mesh according to the different heights of the filling opening. This ensures that the grid mesh is more secure and stable during inspection. The first servo motor drives the first bevel gear to rotate, which in turn drives the meshing second bevel gear. This causes the lead screw, which is fixedly connected to the second bevel gear, to rotate synchronously. The rotation of the lead screw drives the adjusting plate to move up and down through the threaded block, thereby ensuring that the grid mesh can be more stably attached to the ground even in some deep filling openings, preventing the grid mesh from shifting.

One end of the hydraulic rod 110 is fixedly connected to the first connecting block 111, one side of the first connecting block 111 is rotatably connected to the first connecting rod 112, the first connecting rod 112 is rotatably connected to the second connecting rod 113, and the first connecting rod 112 and the second connecting rod 113 are rotatably connected to the second connecting block 114 through a rotating shaft. The other end of the second connecting rod 113 is rotatably connected to the third connecting rod 115. The third connecting rod 115 is rotatably connected to the fourth connecting block 119. One side of the fourth connecting block 119 is rotatably connected to the fifth connecting rod 118. The fifth connecting rod 118 is rotatably connected to the fourth connecting rod 117. The fourth connecting rod 117 is rotatably connected to the third connecting block 116 via a rotating shaft. The bottom of the fourth connecting block 119 is fixedly connected to the cover plate 120. The hydraulic rod 110 drives the first connecting rod 112. The first connecting rod 112 then drives the second connecting rod 113 connected to it via a rotating shaft. The second connecting rod 113 drives the third connecting rod 115. The third connecting rod 115, through the fourth connecting block 119, causes the cover plate 120 to rotate to one side and open according to the fourth connecting rod 117 and the fifth connecting rod 118. This is both convenient and improves the overall opening safety.

[0017] The other end of the hydraulic rod 110 is rotatably connected to the base plate 2, the bottom of the base plate 2 is threadedly connected to the ground 3, the bottom of the cover plate 120 is rotatably connected to the cover opening 4, the cover opening 4 is movably connected to the grid mesh 6 through the spring 5, and an adjustment component 7 is provided on one side of the grid mesh 6. The adjustment assembly 7 includes a first servo motor 701, a first bevel gear 702, a second bevel gear 703, a lead screw 704, a threaded block 705, an adjustment plate 706, and a stabilizing plate 707. The output shaft of the first servo motor 701 is splinedly connected to the first bevel gear 702, which meshes with the second bevel gear 703. The first servo motor 701 drives the first bevel gear 702 to rotate, and the rotation of the first bevel gear 702 drives the meshing second bevel gear 703, so that the lead screw 704, which is fixedly connected to the second bevel gear 703, can rotate synchronously. The rotation of the lead screw 704 drives the adjustment plate 706 to move up and down through the threaded block 705, thereby enabling the grid mesh 6 to be more stably attached to the ground even in some deep areas of the filling port, and avoiding the phenomenon of grid mesh 6 shifting. The bottom of the second bevel gear 703 is fixedly connected to a lead screw 704, the lead screw 704 is threadedly connected to a threaded block 705, and a stabilizing plate 707 is fixedly connected to one side of the threaded block 705. The stabilizing plate 707 is slidably connected to the adjusting plate 706, which is fixedly connected to the grid 6. The bottom of the cover 4 is provided with a flange 8, and the outer and inner surfaces of the flange 8 are provided with sealing gaskets 9.

[0018] In this invention, the working steps of the device are as follows: First step: First, the overall anti-fall device is installed at the filling port. It is sealed by affixing the sealing gasket 9 to the outer ring of the flange 8. Then, according to the different heights of the filling ports, the first servo motor 701 drives the first bevel gear 702 to rotate. The rotation of the first bevel gear 702 drives the meshing second bevel gear 703, so that the screw 704, which is fixedly connected to the second bevel gear 703, can rotate synchronously. The rotation of the screw 704 drives the adjusting plate 706 to move up and down through the threaded block 705 connected by threads. This allows the grid 6 to be more stably attached to the ground in some deeper places at the filling ports, avoiding the phenomenon of grid 6 shifting. It also ensures the stability and safety of the grid 6 even if it is accidentally hit in subsequent use. The second step: Finally, when it is necessary to open the entire cover plate 120, the hydraulic rod 110 can drive the first connecting rod 112. The first connecting rod 112 then drives the second connecting rod 113 connected to it through the rotating shaft. The second connecting rod 113 drives the third connecting rod 115. The third connecting rod 115 then drives the fourth connecting block 119, so that the cover plate 120 can be rotated to one side and opened according to the fourth connecting rod 117 and the fifth connecting rod 118. This is convenient and also improves the safety of opening the entire cover plate 120, without having to spend a lot of manpower to move the cover plate 120.
