Description
Technical Field
[0001] The utility model relates to the technical field of oil tank floating roof limit, in particular to an oil tank floating roof limit device. Background Technique
[0002] An oil tank floating roof, also known as a floating roof oil tank, is a special device for storing liquids (such as petroleum, chemical raw materials, etc.). Based on the buoyancy principle, it can freely float with the rise and fall of the liquid level in the oil tank, thus effectively reducing the volatilization and leakage of the liquid, achieving the purpose of energy conservation, consumption reduction and environmental protection.
[0003] At present, in order to ensure the safe operation of the floating roof in the oil tank and prevent it from colliding with the oil tank wall or internal equipment and causing damage, a limit device is needed to accurately control the movement range of the floating roof. These limit devices are mainly divided into two categories: mechanical limit devices and hydraulic limit devices. Among them, the mechanical limit device stands out with its wide application and excellent performance. The device cleverly uses mechanical structures such as rollers and limit rods to accurately and reliably limit the movement boundary of the floating roof, thus effectively ensuring the stable operation of the floating roof in the oil tank and achieving good use effects.
[0004] However, although the existing mechanical limit devices perform well in ensuring the stable operation of the floating roof in the oil tank, due to the different specifications and sizes of oil tanks, it is difficult for mechanical limit devices to achieve a generally applicable effect. This leads to the necessity of customizing floating roofs of corresponding sizes for different-sized oil tanks, thus increasing the complexity of floating roof production. Content of the Utility Model

Detailed Embodiment
[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. On the contrary, the embodiments of the present utility model include all variations, modifications and equivalents falling within the spirit and scope of the appended claims.
[0021] The oil tank floating disc limiting device according to the embodiment of the present utility model will be described below in conjunction with the drawings.
[0022] The oil tank floating disc limiting device provided by the embodiment of the present utility model can be applied to the limitation of the oil tank floating disc, simplifies the production process of the oil tank floating disc, ensures the universality of the floating disc in oil tanks of different sizes, and thus reduces the complexity of the overall production.
[0023] As shown Figures 1 - 3 in the figure, the oil tank floating disc limiting device of the embodiment of the present utility model may include a disc 1, a transmission assembly 2, a limiting assembly 3, a connection mechanism 4, and an extension assembly 5.
[0024] Among them, the transmission assembly 2 is installed in the middle of the top of the disc 1.
[0025] It should be noted that the transmission assembly 2 described in the above embodiment has the effect of driving the connection mechanism 4.
[0026] The limiting assembly 3 is connected to the inner bottom end of the oil tank.
[0027] It should be noted that under the action of the limiting assembly 3, the installation of the disc 1 in the oil tank is completed.
[0028] The connection mechanism 4 is installed on the outside of the disc 1, and the connection mechanism 4 is in transmission connection with the transmission assembly 2. The connection mechanism 4 may include a connecting plate 41, a mounting bracket 42, a contact plate 43, and a sliding limit assembly 44.
[0029] It should be noted that four groups of the connection mechanisms 4 described in the above embodiment are provided.
[0030] Among them, the connecting plate 41 is in transmission connection with the transmission assembly 2, the mounting bracket 42 is connected to the disc 1, and the connecting plate 41 is slidably penetrated through the mounting bracket 42.
[0031] It can be understood that the mounting bracket 42 described in the above embodiment has the effect of limiting the movement of the connecting plate 41 to ensure that the connecting plate 41 moves in a straight line.
[0032] The contact plate 43 is connected to one end of the connecting plate 41, and the sliding limit assembly 44 is installed on one side of the contact plate 43.
[0033] It should be noted that the contact plate 43 described in the above embodiment has the effect of installing the sliding limit assembly 44, and under the action of the sliding limit assembly 44, while ensuring that the contact plate 43 is always in contact with the inner wall of the oil tank, the friction between the contact plate 43 and the inner wall of the oil tank is reduced.
[0034] The extension assembly 5 is installed between adjacent contact plates 43.
[0035] Specifically, under the action of the extension assembly 5, it is ensured that the adjacent contact plates 43 can always be connected together.
[0036] Specifically, during the actual operation process, when the relevant personnel place the disc 1 inside the oil tank, the disc 1 is installed inside the oil tank through the limiting component 3. Subsequently, under the rotation of the transmission component 2, the connecting plate 41 pushes the contact plate 43 to move towards the inner wall of the oil tank. Under the action of the sliding limit component 44, the contact plate 43 comes into contact with the inner wall of the oil tank. At the same time, the sliding limit component 44 reduces the friction when the contact plate 43 contacts the inner wall of the oil tank. Subsequently, under the action of the extension component 5, while ensuring that the adjacent contact plates 43 are always connected together, the contact area between the contact plate 43 and the oil surface is increased, avoiding the problem of the buoyancy of the disc 1 decreasing due to the small contact area, simplifying the production process of the floating disc of the oil tank, ensuring the universality of the floating disc in oil tanks of different sizes, and thus reducing the complexity of the overall production.
[0037] In an embodiment of the present invention, as Figures 1 - 3 shown, the transmission component 2 may include a rotating ring 21, a threaded column 22, a transmission rod 23, and a sliding rod 24.
[0038] It should be noted that four groups of the above-described transmission rods 23 are provided.
[0039] Among them, the rotating ring 21 is rotatably installed in the middle of the disc 1. The threaded column 22 rotatably penetrates through the disc 1. The rotating ring 21 is threadedly sleeved on the outer side of the threaded column 22. The transmission rod 23 is hinged to the rotating ring 21. One end of the transmission rod 23 away from the rotating ring 21 is hinged to the connecting plate 41.
[0040] It should be noted that after the rotating ring 21 is connected to the threaded column 22, the rotation of the rotating ring 21 is used to drive the transmission rod 23. Under the push of the transmission rod 23, the connecting plate 41 expands outwards. At the same time, since the rotating ring 21 and the threaded column 22 are threadedly connected, the situation where the rotating ring 21 rotates selflessly and causes the connecting plate 41 to retract is avoided.
[0041] The sliding rod 24 is connected to the inner bottom end of the oil tank. The threaded column 22 is slidably sleeved on the outer side of the sliding rod 24.
[0042] It should be noted that a slider is fixedly connected to the inner side of the above-described threaded column 22, and a through groove for the slider to slide is provided on the outer side of the sliding rod 24.
[0043] It can be understood that under the action of the sliding rod 24, it is ensured that the threaded column 22 can slide up and down inside the oil tank.
[0044] In an embodiment of the present invention, as Figures 1 - 3 shown, the limiting component 3 may include a limiting column 32.
[0045] It should be noted that four sets of limit posts 32 are provided in the above embodiments.
[0046] Among them, the limit posts 32 are connected to the inner bottom end of the oil tank. A limit hole 31 is opened through the top end of the disc 1, and the limit hole 31 is slidably penetrated through the limit posts 32.
[0047] As a possible situation, sliding beads can be installed on the outer side of the limit posts 32 to reduce the frictional force generated between the limit posts 32 and the limit hole 31 when the limit posts 32 slide in the limit hole 31, and ensure the smoothness of the disc 1 when lifting and lowering in the oil tank.
[0048] Specifically, under the action of the limit posts 32, the disc 1 is installed inside the oil tank. At the same time, because multiple sets of limit posts 32 are provided, the situation that the disc 1 rotates in the oil tank is avoided.
[0049] In an embodiment of the present invention, as Figures 1 - 3 shown, the sliding limit assembly 44 may include rolling beads 441, a clamping plate 442, and a rubber sheath 443.
[0050] It can be understood that under the action of the rubber sheath 443, the probability of generating sparks when the rolling beads 441 slide in contact with the inside of the oil tank is reduced, ensuring the safety of the oil tank.
[0051] Among them, the rolling beads 441 are rotatably installed on one side of the contact plate 43. The clamping plate 442 is fixedly connected to one side of the contact plate 43, and a clamping groove for the clamping plate 442 to be clamped is opened in the middle of the rolling beads 441.
[0052] It should be noted that under the action of the clamping plate 442 and the clamping groove, it is ensured that the rolling beads 441 can only roll up and down, further avoiding the situation that the disc 1 rotates inside the oil tank caused by the left and right rolling of the rolling beads 441.
[0053] The rubber sheath 443 is fixedly connected to the outer side of the rolling beads 441.
[0054] Specifically, under the action of the clamping plate 442, the rolling mode of the rolling beads 441 is limited. At the same time, under the action of the rubber sheath 443, the situation of generating sparks when the rolling beads 441 roll is avoided, ensuring the safety of the oil tank.
[0055] In an embodiment of the present invention, as Figures 1 - 3 shown, the extension assembly 5 may include a connecting sleeve 51 and an extension rod 52.
[0056] It should be noted that four sets of the connecting sleeve 51 and the extension rod 52 described in the above embodiments are provided.
[0057] Among them, the connecting sleeve 51 is connected to one end of the contact plate 43, the extended sleeve rod 52 is connected to another group of contact plates 43, and one end of the extended sleeve rod 52 is slidably inserted into the interior of the connecting sleeve 51.
[0058] Specifically, under the action of the connecting sleeve 51 and the extended sleeve rod 52, it is ensured that the adjacent contact plates 43 are always connected together. At the same time, the contact area between the contact plate 43 and the oil surface inside the oil tank is increased, ensuring the buoyancy of the disc 1 inside the oil tank.
[0059] In summary, for the oil tank floating disc limiting device of the embodiment of the present utility model, under the action of the limiting component, the situation that the disc rotates inside the oil tank is avoided. At the same time, under the drive of the transmission component, the connecting mechanism is expanded, and with the assistance of the extension component, it is ensured that the expanded connecting mechanism is always connected together, simplifying the production process of the oil tank floating disc, ensuring the versatility of the floating disc in oil tanks of different sizes, and thus reducing the complexity of the overall production.
