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-volatilization floating roof support pillar. Background Art

[0002] The floating roof support pillar supports the floating roof when it touches the bottom in the floating roof oil tank. The pillar rod in the floating roof support pillar is fixed in the sleeve on the floating roof through bolts. Due to technological 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. 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, posing a certain degree of safety hazard. Summary of the Invention

[0023] 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.

[0024] Combined with the attached Figures 1-5 A self-sealing anti-volatile floating roof strut described above includes a strut sleeve 1, and a floating roof strut 2 is installed inside the strut sleeve 1. The strut sleeve 1 is located on the floating roof and is fixedly connected. Insertion grooves are provided on both the strut sleeve 1 and the floating roof strut 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 strut sleeve 1 and the floating roof strut 2. The gap between the strut sleeve 1 and the floating roof strut 2 is blocked by the sealing end of the self-sealing connection mechanism 3.

[0025] A contact plate is provided at the top end of the strut sleeve 1, and bolt grooves arranged at equal distances are provided on the contact plate.

[0026] A fixing plate is fixedly connected to the floating roof strut 2, and bolt grooves are also provided on the fixing plate.

[0027] The contact plate on the strut sleeve 1 and the fixing plate on the floating roof strut 2 are connected by bolts, and a sealing gasket is provided between the contact plate and the fixing plate.

[0028] The self-sealing connection mechanism 3 includes a main body rod 301, a nut 302, an adjusting screw rod 303, a pushing block 304, a moving rod 305, a pushing rod 306, and an insertable 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 outside the floating roof support 2. Installation grooves are respectively provided at both ends of the main body rod 301, and an adjusting screw rod 303 is installed in the installation groove. A pushing block 304 is installed at one end of the adjusting screw rod 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 an insertable 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.

[0029] 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 communicate with each other. The notch of the circular groove is located on the outer wall of the main body rod 301.

[0030] The adjusting screw rod 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 rod 303 located in the threaded groove.

[0031] 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 circle 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 in a blade shape. 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.

[0032] Equally spaced pushing grooves are provided in the insertable cushion block 307, and a moving rod 305 is installed in the pushing grooves.

[0033] 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. By pushing the pointed part of the insertable cushion block 307 through the moving rod 305, the insertable cushion block 307 can be telescoped, causing a local change in the insertable cushion block 307 to block the gap between the main body rod 301 and the insertion groove.

[0034] 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 so that the inserted pads 307 are aligned 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 to block the gap between the insertion groove and the floating roof support column 2 and the support column sleeve 1, preventing oil and gas from leaking from 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.
