Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for floating roof oil cylinders, and in particular to a self-sealing anti-volatile floating roof support pillar. Background Art

[0002] The floating roof support pillar supports the floating roof when it touches the bottom of the floating roof oil tank. The pillar rod in the floating roof support pillar is fixed in the sleeve on the floating roof by bolts. Due to process reasons, there is a certain gap between the outer wall of the pillar rod and the inner wall of the sleeve. The oil and gas in the floating roof oil tank will leak from the gap, especially at the position where the bolts are fixed. Since there are thread grooves on the surface of the bolts, the gasket cannot completely fill the thread grooves on the surface of the bolts, and there will be a gap at the connection between the screw rod and the nut, and the oil and gas will leak from the gap at the connection between the screw rod and the nut. When the oil and gas leak to a certain extent, it is very easy to form a flammable area, and there are certain safety hazards. Summary of the Invention

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with the attached Figures 1 - 5 A self-sealing anti-volatile floating roof support described above includes a support sleeve 1, and a floating roof support 2 is installed inside the support sleeve 1. The support sleeve 1 is located on the floating roof and is fixedly connected. Insertion grooves are provided on both the support sleeve 1 and the floating roof support 2, and the positions of the insertion grooves correspond to each other and are interconnected. A self-sealing connection mechanism 3 is installed in the insertion groove, and the position of the sealing end of the self-sealing connection mechanism 3 corresponds to the gap between the support sleeve 1 and the floating roof support 2. The gap between the support sleeve 1 and the floating roof support 2 is blocked by the sealing end of the self-sealing connection mechanism 3.

[0018] A contact plate is provided at the top end of the support sleeve 1, and bolt grooves arranged at equal intervals are provided on the contact plate.

[0019] A fixing plate is fixedly connected to the floating roof support 2, and bolt grooves are also provided on the fixing plate.

[0020] The contact plate on the support sleeve 1 and the fixing plate on the floating roof support 2 are connected by bolts, and a sealing gasket is provided between the contact plate and the fixing plate.

[0021] The self-sealing connection mechanism 3 includes a main body rod 301, a nut 302, an adjusting screw 303, a pushing block 304, a moving rod 305, a pushing rod 306, and a plug-in cushion block 307. The main body rod 301 is located in the insertion groove and is slidably connected. Nuts 302 are respectively threadedly connected to both ends of the main body rod 301 located outside the floating roof support 2. Installation grooves are respectively provided at both ends of the main body rod 301, and adjusting screws 303 are installed in the installation grooves. A pushing block 304 is installed at one end of the adjusting screw 303, and equally spaced pushing rods 306 are rotatably connected to the pushing block 304. One end of the pushing rod 306 is rotatably connected to a moving rod 305, and a plug-in cushion block 307 is installed at one end of the moving rod 305 located in the gap between the support sleeve 1 and the floating roof support 2.

[0022] The installation groove is composed of a threaded groove, a sliding groove and a circular groove, and the threaded groove, the sliding groove and the circular groove are interconnected. The notch of the circular groove is located on the outer wall of the main body rod 301.

[0023] The adjusting screw 303 is located in the threaded groove and is threadedly connected, and a pushing block 304 is rotatably connected to one end of the adjusting screw 303 located in the threaded groove.

[0024] The insertable cushion block 307 is an annular cushion block. The insertable cushion block 307 is located in the circular groove, and the inner wall of the inner ring of the insertable cushion block 307 is fixedly connected to the groove wall of the circular groove. The thicker end of the insertable cushion block 307 is filled in the circular groove to seal the circular groove and prevent oil and gas from leaking out of the circular groove. One side of the insertable cushion block 307 located in the gap between the support sleeve 1 and the floating roof support 2 is blade-shaped. The insertable cushion block 307 is similar to a disc blade shape, and the pointed part is easy to insert into the gap between the support sleeve 1 and the floating roof support 2. In the initial state, the pointed part of the insertable cushion block 307 is flush with the outer wall of the main body rod 301.

[0025] The insertable cushion block 307 is provided with equally spaced pushing grooves, and moving rods 305 are installed in the pushing grooves.

[0026] The moving rod 305 is located in the sliding groove and is slidably connected, and the end face of the moving rod 305 located at one end of the circular groove is fixedly connected to the innermost groove wall of the pushing groove. The pointed part of the insertable cushion block 307 is moved by the moving rod 305, so that the insertable cushion block 307 expands and contracts, and the insertable cushion block 307 undergoes local changes to block the gap between the main body rod 301 and the insertion groove.

[0027] For the described self-sealing anti-volatile floating roof support column, during use, the staff inserts the floating roof support column 2 into the support column sleeve 1 on the floating roof and fixes it with bolts at the top. After the position of the floating roof support column 2 is fixed, the main body rod 301 is inserted into the insertion groove, and the position of the floating roof support column 2 is radially restricted by the main body rod 301 to prevent the floating roof support column 2 from falling off after touching the bottom. The positions of the inserted pads 307 aligned by the nuts 302 at both ends of the main body rod 301 are adjusted to align the inserted pads 307 with the gap between the floating roof support column 2 and the support column sleeve 1. By rotating the adjusting screw 303, the pushing block 304 is driven to move. During the movement of the pushing block 304, the pushing rod 306 is driven to move. By the movement of the pushing rod 306, the moving rod 305 is pushed to extend outwards. By the movement of the moving rod 305, the pointed part of the inserted pad 307 is pushed to extend, so that the pointed part of the inserted pad 307 is inserted into the gap between the floating roof support column 2 and the support column sleeve 1, sealing the gap between the insertion groove and the floating roof support column 2 and the support column sleeve 1 to prevent oil and gas from leaking through the gap between the insertion groove and the main body rod 301. At the same time, after the inserted pad 307 is inserted, it will support the position of the floating roof support column 2 in the support column sleeve 1 and absorb the impact force generated when the floating roof support column 2 touches the bottom.

Although the present invention is specifically shown and introduced in combination with the preferred implementation, there are many methods and ways to specifically implement this technical solution. The above is only the preferred implementation of the present invention, but those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all are within the protection scope of the present invention.
