Description

Technical Field

[0001] This utility model relates to an adjustable outrigger for an internal floating roof. Background Technology

[0002] During oil storage and transportation, due to limitations in technology and equipment, some light components in crude oil and light oils (such as gasoline) are easily released into the air, resulting in significant evaporation losses. In recent years, thanks to the application of floating roof tanks and internal floating roof tanks, the upgrading of floating roof equipment, and the implementation of other energy-saving measures, oil losses have been brought under control.

[0003] To enable adjustment of the space between the floating roof and the storage tank, the applicant previously filed an adjustable support leg for a vertical storage tank floating roof, comprising a support leg body, wherein the support leg body has at least a first switching position and a second switching position, the height between the first switching position and the lower end of the support leg body and the height between the second switching position and the lower end of the support leg body are not equal; the adjustable support leg further includes: a sleeve for fixing the floating roof body, the sleeve being loosely fitted on the support leg body; and a locking component fitted on the support leg body, wherein when the support leg body moves relative to the sleeve, such that the first switching position or the second switching position on the support leg body engages with one end of the sleeve, the locking component engages with one end of the support leg body and one end of the sleeve respectively, thereby fastening the sleeve and the support leg body together.

[0004] The process of using the aforementioned adjustable outrigger is as follows: After fixing the outrigger body to the floating roof body, pass the outrigger body through the sleeve. Place the tensioning component onto the outrigger body, and pre-connect the nut to the sleeve, thus confining the tensioning component between the outrigger body, the nut, and the sleeve. Move the outrigger body axially along the sleeve, select a first or second switching position on the outrigger body, and mate it with one end of the sleeve. Further connect the nut to the sleeve; the nut exerts a compressive force on the tensioning component, causing it to deform, i.e., shorten in the axial direction.

[0005] Although the adjustable outriggers described above can adjust the height of the floating roof, it requires one end of the lifting component to pass through the support plate and connect to the first end cap, so that the support plate is clamped between the lifting component and the outrigger body or the first end cap. Then, the nut is threadedly connected to the sleeve. When the outrigger body, sleeve, nut, and tensioning component are locked together, the stepped surface of the stepped hole on the nut cooperates with the support plate, and the support plate provides support force to the nut. It can be seen that when the adjustable outriggers are switched, the first end cap and the lifting component need to be operated. Several outriggers are installed on each floating roof, and each outrigger adjustment requires operation, which is quite complicated. Utility Model Content

[0006] This invention provides an adjustable outrigger for an internal floating roof, which is simple to operate when adjusting the height of the outrigger.

[0007] The technical solutions to the above technical problems are as follows:

[0008] The adjustable outriggers of the internal floating roof include outriggers, a sleeve for passing through and being fixed to the floating roof, the outriggers passing through the sleeve, a clamping assembly for clamping the outriggers, and a support plate for connecting to and supporting the clamping assembly. The support plate is fixed to the sleeve. The clamping assembly includes a first clamping block, a second clamping block, a first bolt, and a first nut. The first clamping block and the second clamping block are respectively fixed to the support plate. The first clamping block has a first groove and a first mounting hole, and the second clamping block has a second groove and a second mounting hole. The outriggers mate with the first groove and the second groove respectively. The first bolt passes through the first mounting hole and the second mounting hole and is connected to the first nut, so that the outriggers are clamped by the first clamping block and the second clamping block.

[0009] Furthermore, the clamping assembly also includes a second bolt, a third bolt, a second nut, and a third nut. The support plate is provided with a plurality of first through holes. The first clamping block is provided with a first mounting hole, and the second clamping block is provided with a second mounting hole. The second bolt passes through the first mounting hole and the first through hole and connects with the second nut to fix the first clamping block to the support plate. The third bolt passes through the second mounting hole and connects with the third nut to fix the second clamping block to the support plate.

[0010] The width of the first mounting hole is greater than the diameter of the second bolt shank, and the width of the second mounting hole is greater than the diameter of the third bolt shank. When the first bolt and the first nut lock the first clamping block and the second clamping block, the force of the first bolt and the first nut causes the first clamping block and the second clamping block to move.

[0011] Furthermore, both the first clamping block and the second clamping block include a fixed block and a movable clamping block. The fixed block is fixed to the support plate and is provided with a T-shaped slide rail. The lower end face of the movable clamping block is provided with a T-shaped guide groove. The T-shaped guide groove and the T-shaped slide rail slide together to make the movable clamping block movably connected to the fixed block. The first mounting hole and the second mounting hole are respectively provided on the movable clamping block.

[0012] Furthermore, the first groove has a first protruding tooth and a first tooth groove on its groove wall surface, and the first protruding tooth and the first tooth groove are arranged alternately along the axial direction of the first clamping block. The second groove has a second protruding tooth and a second tooth groove on its groove wall surface, and the second protruding tooth and the second tooth groove are arranged alternately along the axial direction of the second clamping block.

[0013] The outer peripheral surface of the support leg is provided with protruding teeth and tooth grooves. The protruding teeth and tooth grooves are arranged at intervals along the axial direction of the support leg. After the support leg is engaged with the first groove and the second groove respectively, the protruding teeth are engaged with the first tooth groove and the second tooth groove respectively, and the tooth grooves are engaged with the first protruding teeth and the second protruding teeth respectively.

[0014] In this invention, when the height of the outrigger needs to be adjusted, the threaded connection of the first bolt and the first nut is loosened to release the clamping of the first and second clamping blocks on the outrigger, thus adjusting the outrigger height. After adjustment to the desired position, the first and second clamping blocks are re-locked using the first bolt and the first nut to clamp the outrigger. Compared with the prior art, this invention simplifies the operation by requiring only the loosening of the bolts to adjust the outrigger height. Attached Figure Description

Detailed Implementation

[0024] like Figures 1 to 7 As shown, the adjustable support leg of the internal floating roof of this utility model includes a support leg 1, a sleeve 2 for passing through and being fixed to the floating roof A, a clamping assembly for clamping the support leg 1, and a support plate 3 for connecting and supporting the clamping assembly. Preferably, a support plate B is provided inside the floating roof A, and the support plate B is welded to the sleeve 2, thereby fixing the sleeve 2 and the floating roof A into one piece.

[0025] The support leg 1 passes through the sleeve 2, and the support leg 1 and the sleeve 2 are fitted with a clearance. Preferably, multiple sealing components are fixed on the outer peripheral surface of the support leg 1. The sealing components are fitted with the inner wall surface of the sleeve 2 to seal the gap between the support leg 1 and the sleeve 2, so as to prevent oil and gas from escaping from the gap between the support leg 1 and the sleeve 2. A first annular groove and a second annular groove are provided on the outer peripheral surface of the support leg 1. The sealing components include a sealing ring and a retaining ring. The sealing ring is fitted with the first annular groove, the retaining ring is fitted with the second annular groove, and the retaining ring is fitted with the axial end face of the sealing ring to limit the axial displacement of the sealing ring.

[0026] The support plate 3 is fixed to the sleeve 2. The diameter of the support plate 3 is larger than the diameter of the sleeve 2. The support plate 3 is ring-shaped and is fitted onto the support leg 1. The support plate 3 is located at the end of the sleeve 2. The support plate 3 and the sleeve 2 are preferably fixed by welding.

[0027] The clamping assembly includes a first clamping block 4, a second clamping block 5, a first bolt 6, and a first nut 6a. The first clamping block 4 and the second clamping block 5 are respectively fixed to the support plate 3. The first clamping block 4 is provided with a first groove 4a and a first mounting hole 4b, and the second clamping block 5 is provided with a second groove 5a and a second mounting hole 5b. The support leg 1 is respectively engaged with the first groove 4a and the second groove 5a. The first bolt 6 passes through the first mounting hole 4b and the second mounting hole 5b and is connected to the first nut 6a, so that the support leg 1 is clamped by the first clamping block 4 and the second clamping block 5. Since the first clamping block 4 and the second clamping block 5 are also fixed to the support plate 3, the support leg 1 and the support plate 3 are fixed together by the clamping assembly. With this structure, the support leg 1 can be adjusted to the required position and then fixed together with the support plate 3 by the clamping assembly.

[0028] The preferred structure for fixing the first clamping block 4 and the second clamping block 5 to the support plate 3 is as follows: the clamping assembly further includes a second bolt 7, a third bolt 8, a second nut 9, and a third nut 10. The support plate 3 is provided with multiple first through holes 3a. The first clamping block 4 is provided with a first mounting hole 4c. The second clamping block 5 is provided with a second mounting hole 5c. The second bolt 7 passes through the first mounting hole 4c and the first through hole 3a and connects with the second nut 9 to fix the first clamping block 4 to the support plate 3. The third bolt 8 passes through the second mounting hole 5c and connects with the third nut 10 to fix the second clamping block 5 to the support plate 3.

[0029] The width of the first mounting hole 4c is greater than the diameter of the shank of the second bolt 7, and the width of the second mounting hole 5c is greater than the diameter of the shank of the third bolt 8. When the first bolt 6 and the first nut 6a lock the first clamping block 4 and the second clamping block 5, the force of the first bolt 6 and the first nut 6a causes the first clamping block 4 and the second clamping block 5 to be displaced. When it is necessary to clamp the support leg 1 through the first clamping block 4 and the second clamping block 5, the first bolt 6 is first passed through the first mounting hole 4b and the second mounting hole 5b and then connected to the first nut 6a. During the process of fixing the first clamping block 4 and the second clamping block 5 by the first bolt 6 and the first nut 6a, the first clamping block 4 and the second clamping block 5 are displaced by the force, so that the support leg 1 is clamped by the first clamping block 4 and the second clamping block 5. The first assembly hole 4c and the second assembly hole 5c still correspond to the first through hole 3a respectively. Then, the second bolt 7 is passed through the first assembly hole 4c and the first through hole 3a and connected to the second nut 9 to fix the first clamping block 4 to the support plate 3. Finally, the third bolt 8 is passed through the second assembly hole 5c and connected to the third nut 10 to fix the second clamping block 5 to the support plate 3.

[0030] After the support leg 1 is clamped by the first clamping block 4 and the second clamping block 5, in order to avoid relative axial displacement between the support leg 1 and the clamping assembly, a first protruding tooth 4d and a first tooth groove 4e are provided on the groove wall surface of the first groove 4a. The first protruding tooth 4d and the first tooth groove 4e are arranged alternately along the axial direction of the first clamping block 4. A second protruding tooth 5d and a second tooth groove 5e are provided on the groove wall surface of the second groove 5a. The second protruding tooth 5d and the second tooth groove 5e are arranged alternately along the axial direction of the second clamping block 5. A protruding tooth 1a and a tooth groove 1b are provided on the outer peripheral surface of the support leg 1. The protruding tooth 1a and the tooth groove 1b are arranged at intervals along the axial direction of the support leg 1. After the support leg 1 is engaged with the first groove 4a and the second groove 5a respectively, the protruding tooth 1a engages with the first tooth groove 4e and the second tooth groove 5e respectively, and the tooth groove 1b engages with the first protruding tooth 4d and the second protruding tooth 5d respectively.

[0031] Another possible structure for fixing the first clamping block 4 and the second clamping block 5 to the support plate 3 is as follows: Figure 8As shown, both the first clamping block 4 and the second clamping block 5 include a fixed block 40 and a movable clamping block 41. The fixed block 40 is fixed to the support plate 3. The fixed block 40 and the support plate 3 can be integrally formed, fixed by welding, or fixed by bolts. A first groove 4a and a first mounting hole 4b are provided on the movable clamping block 41 in the first clamping block 4. A second groove 5a and a second mounting hole 5b are provided on the movable clamping block 41 in the second clamping block 5. The fixed block 40 is provided with a T-shaped slide rail 42. The lower end face of the movable clamping block 41 is provided with a T-shaped guide groove 43. The T-shaped guide groove 43 and the T-shaped slide rail 42 slide together to movably connect the movable clamping block 41 and the fixed block 40. The first mounting hole 4b and the second mounting hole 5b are respectively provided on the movable clamping block 41. The T-shaped guide groove 43 and the T-shaped slide rail 42 cooperate to form a connection between the movable clamping block 41 and the fixed block 40 in the axial direction. At the same time, the fixed block 40 supports the movable clamping block 41. When the movable clamping block 41 supports the support leg 1, the movable clamping block 41, the support leg 1, and the fixed block 40 form a whole.
