Description

Technical Field

[0001] The invention relates to the technical field of gas storage tanks, in particular to a natural gas storage tank supporting device and an adjusting method thereof. Background Art

[0002] The existing natural gas storage tank has a tank body and a supporting device that are fixedly connected; the supporting device is mostly a block structure, which is attached to the bottom of the gas storage tank and then welded and fixed, so that the supporting block can be used to support the gas storage tank off the ground during use.

[0003] When the gas tank is in use, it needs to be kept horizontal, and its interface needs to be at the same level as the pipe used on site. However, the above-mentioned gas tank support device makes it impossible to adjust the position of the gas tank. Therefore, when the gas tank is placed for use, it is necessary to spend a lot of effort to rectify the ground where it is placed. This is not only labor-intensive, but also has low precision in ground rectification, resulting in low efficiency. Summary of the invention

[0004] In order to solve the technical problems in the background technology, the present invention discloses a natural gas storage tank supporting device and an adjusting method thereof.

[0005] The present invention provides a natural gas storage tank support device, comprising a support frame for supporting the gas storage tank;

[0006] There are two support frames, which are respectively located at two ends of the gas storage tank;

[0007] The support frame is provided with a U-shaped placement groove with an opening upward; parts on both sides of the placement groove are provided as side arms; and a support block is provided at the bottom of the placement groove;

[0008] The gas tank is placed between the slots and is hinged to the side arms so that the angle between the support frame and the ground can be adjusted;

[0009] A horizontally arranged, rotatable driving rod is provided at the upper end of the side arm;

[0010] The inner end of the driving rod is threadedly connected with a tooth block, the side of the tooth block is provided with a latching tooth, and the gas storage tank is provided with a tooth groove corresponding to the latching tooth;

[0011] A worm gear is arranged on the outer side of the support block, a transmission rod is inserted in the side arm, and a worm meshing with the worm gear is arranged at the lower end of the transmission rod;

[0012] The upper end of the transmission rod is fixedly connected with a driven bevel gear;

[0013] The upper end of the driven bevel gear is vertically meshed with the driving bevel gear;

[0014] The active bevel gear is sleeved and fixed on the driving rod;

[0015] The driving rod is rotated to drive the tooth block to move axially, so that the latching teeth engage or disengage from the tooth groove, and at the same time the supporting block is driven to rise and fall;

[0016] The movement of the latch tooth approaching the tooth groove is synchronized with the movement of the support block rising;

[0017] The movement of the latch teeth away from the tooth groove is synchronized with the movement of the support block descending;

[0018] The length of the tooth groove is configured such that when the support block abuts against the gas storage tank, the latching teeth are still engaged with the tooth groove.

[0019] The beneficial effects of the above arrangement are: 1. The lower end of the support frame is on the ground, and the angle between the support frame and the horizontal plane can be adjusted by swinging the support frame, thereby adjusting the height and horizontal position of the drive rod, and the height and horizontal position of the connection between the gas tank and the support frame are also changed, so as to achieve the purpose of adjusting the height of the gas tank and adjusting the angle with the ground, so that the gas tank reaches the set height and reaches a horizontal position; 2. The driving rod rotates, and the axial movement of the latch tooth and the lifting and lowering of the support block can be adjusted at the same time, thereby simplifying the structure of the device and reducing the cost.

[0020] The tooth grooves are directly arranged on the tank body of the gas storage tank, which will cause the thickness of the tank body to become smaller and reduce its strength. Based on this, a further improvement is that two centrally symmetrical and equal-height connecting blocks are arranged at both ends of the gas storage tank; the tooth grooves are arranged on the connecting blocks.

[0021] The specific installation structure of the driving rod is as follows: a horizontally arranged plug hole is provided in the side arm, and the driving rod is plugged into the plug hole; an external thread column is provided at the inner end of the driving rod, and the outer end protrudes outward from the side arm; the outer end of the tooth block is connected to a screw sleeve threadedly connected to the external thread column.

[0022] Since the tooth block easily rotates with the driving rod, it is difficult for the locking tooth to accurately engage with the tooth groove. Based on this, a further improvement is that: the plug-in hole is located at the position of the external threaded column to radially lead out a limit groove; the outer wall of the screw sleeve radially leads out a limit block that engages the limit groove.

[0023] The present invention also provides a method for adjusting a natural gas storage tank support device, using the natural gas storage tank support device, comprising the following steps:

[0024] S1. Hoist the fixedly connected natural gas storage tank support device and the gas storage tank to the target location;

[0025] S2. Use a crane to fix the gas tank;

[0026] S3, rotating the driving rod, so that the latching teeth move to the outside of the support frame and disengage from the tooth groove, and the support block descends and disengages from the gas storage tank;

[0027] S4. Use a crane to move the gas tank to the set height and keep it level;

[0028] S5. Swing the support frame. On the premise that the lower end of the support frame is against the ground, adjust the angle between the support frame and the horizontal plane and the height of the driving rod so that the latching teeth are directly opposite to the tooth grooves.

[0029] S6, rotating the driving rod in the opposite direction, so that the latching teeth engage with the tooth grooves, so that the support block rises and abuts against the gas storage tank;

[0030] S7. The crane is separated from the gas tank and the adjustment is completed.

[0031] The beneficial effects of the present invention are: 1. The lower end of the support frame is on the ground, and the angle between the support frame and the horizontal plane can be adjusted by swinging the support frame, thereby adjusting the height and horizontal position of the driving rod, and the height and horizontal position of the connection between the gas tank and the support frame are also changed, so as to achieve the purpose of adjusting the height of the gas tank and adjusting the angle with the ground, so that the gas tank reaches the set height and reaches a horizontal position; 2. The driving rod rotates, and the axial movement of the latch tooth and the lifting and lowering of the support block can be adjusted at the same time, thereby simplifying the structure of the device and reducing the cost; 3. The adjustment operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0039] Embodiment 1:

[0040] like Figure 1-3As shown, the present invention discloses a natural gas storage tank support device, including a support frame 1 for supporting a gas storage tank 2. Two support frames 1 are provided, and are respectively located at the two ends of the gas storage tank 2. The support frame 1 is provided with a U-shaped placement groove 3 with an opening facing upward; the parts on both sides of the placement groove 3 are provided with side arms 101. A support block 4 is provided at the bottom of the placement groove 3; the top projection of the support block 4 is a rectangle, which is inserted into the bottom of the placement groove 3 and a rectangular groove 102 that imitates the support block 4, and is used for guiding the lifting of the support block 4. The lower end of the rectangular groove 102 is connected to a lifting groove 103, and its length is greater than the rectangular groove 102, so that the lifting groove 103 and the rectangular groove 102 form a T-shaped groove. A connecting column extends downward from the lower end of the support block 4, and a worm gear 7 arranged in the lifting groove 103 is sleeved on the connecting column.

[0041] The gas storage tank 2 is located between the placement slots 3 and is hinged to the side arm 101, so that the angle between the support frame 1 and the ground can be adjusted. The specific structure is as follows: Figure 4 As shown, a horizontally arranged plug hole is provided at the upper end of the side arm 101, and a driving rod 5 is inserted into the plug hole. An external thread column 51 is provided at the inner end of the driving rod 5, and the outer end passes outward from the side arm 101, and a rotation connection is realized through a bearing clamped in the plug hole.

[0042] The inner end of the driving rod 5 is threadedly connected with a tooth block 6, and the side of the tooth block 6 is provided with a latching tooth 61. Two centrally symmetrical and equal-height connecting blocks 11 are provided at both ends of the gas storage tank 2, and tooth grooves 21 corresponding to the latching teeth 61 are provided on the connecting blocks 11. When the driving rod 5 rotates, the driving tooth block 6 moves axially and engages or disengages from the tooth grooves 21.

[0043] The plug hole is located at the position of the external thread column 51 and radially leads to two symmetrically arranged limiting grooves 52; the outer wall of the screw sleeve 62 radially leads to a limiting block 63 that engages with the limiting groove 52. The limiting block 63 engages with the limiting groove 52 to limit the tooth block 6 and prevent the tooth block 6 from rotating with the driving rod 5.

[0044] A transmission rod 8 is inserted into the side arm 101 and is rotatably connected via a bearing. A worm 81 is provided at the lower end of the transmission rod 8 and meshes with the worm wheel 7. The rotation of the transmission rod 8 can drive the worm wheel 7 to rise and fall, thereby driving the support block 4 to rise and fall.

[0045] The upper end of the transmission rod 8 is fixedly connected with a driven bevel gear 9; the upper end of the driven bevel gear 9 is vertically meshed with an active bevel gear 10; the active bevel gear 10 is sleeved and fixed on the driving rod 5. In this way, the driving rod 5 rotates to drive the tooth block 6 to move axially, so that the latching teeth 61 are engaged with or disengaged from the tooth groove 21, and the support block 4 is driven to rise and fall at the same time. Moreover, the movement of the latching teeth 61 approaching the tooth groove 21 is synchronized with the movement of the support block 4 rising; the movement of the latching teeth 61 away from the tooth groove 21 is synchronized with the movement of the support block 4 falling. The length of the tooth groove 21 is configured as follows: when the support block 4 rises and abuts against the gas tank 2, the axial movement of the latching teeth 61 will not be blocked, and the latching teeth 61 are always engaged with the tooth groove 21.

[0046] Compared with the prior art, the beneficial effects of this embodiment are: 1. The lower end of the support frame 1 is on the ground, and the angle between the support frame 1 and the horizontal plane can be adjusted by swinging the support frame 1, thereby adjusting the height and horizontal position of the drive rod 5, and the height and horizontal position of the connection between the gas tank 2 and the support frame 1 are also changed, so as to achieve the purpose of adjusting the height of the gas tank 2 and the angle with the ground, so that the gas tank 2 reaches the set height and reaches a horizontal position; 2. The drive rod 5 rotates, and the axial movement of the latch tooth 61 and the lifting and lowering of the support block 4 can be adjusted at the same time, thereby simplifying the structure of the device and reducing the cost.

[0047] Embodiment 2:

[0048] The present invention also discloses a method for adjusting a natural gas storage tank 2 support device, using the natural gas storage tank 2 support device, comprising the following steps:

[0049] S1, hoisting the fixedly connected natural gas storage tank 2 support device and the gas storage tank 2 to the target position;

[0050] S2, use a crane to fix the gas storage tank 2;

[0051] S3, rotating the driving rod 5, so that the latching teeth 61 move to the outside of the support frame 1 and disengage from the tooth groove 21, and the support block 4 descends and disengages from the gas storage tank 2;

[0052] S4. Use a crane to move the gas storage tank 2 to a set height and keep it level;

[0053] S5, swing the support frame 1, and adjust the angle between the support frame 1 and the horizontal plane while ensuring that the lower end of the support frame 1 is against the ground, and adjust the height of the driving rod 5 so that the latching tooth 61 is directly opposite to the tooth groove 21;

[0054] S6, reversely rotate the driving rod 5 so that the latching teeth 61 engage with the tooth grooves 21, so that the supporting block 4 rises and abuts against the gas storage tank 2;

[0055] S7, the crane is separated from the gas tank 2, and the adjustment is completed.

[0056] The above method makes the adjustment operation simple and convenient.

[0057] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
