Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas storage tanks, in particular to a natural gas storage tank supporting device and a method for adjusting the same. BACKGROUND

[0002] The existing natural gas storage tank has a fixed connection between the tank body and the supporting device; the supporting device is mostly in 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 for off-ground support during use of the gas storage tank.

[0003] During use of the gas storage tank, it needs to be kept in a horizontal state, and its interface needs to be at the same horizontal position as the field-used connecting pipe. However, the above-mentioned supporting device of the gas storage tank cannot adjust the position of the gas storage tank. Therefore, when the gas storage tank is placed for use, a lot of effort needs to be spent on modifying the ground where it is placed for use, which not only has a high labor intensity, but also has a low precision of ground modification, resulting in a low efficiency. SUMMARY

[0004] To solve the technical problems in the background art, the present application discloses a natural gas storage tank supporting device and a method for adjusting the same.

[0005] The present application provides a natural gas storage tank supporting device, which comprises a supporting frame for supporting the gas storage tank.

[0006] The supporting frame is provided with two supporting frames, which are respectively located at two ends of the gas storage tank.

[0007] The supporting frame is provided with a U-shaped placement groove with an upward opening; the part on both sides of the placement groove is provided with a side arm; and the groove bottom of the placement groove is provided with a supporting block.

[0008] The gas storage tank is placed between the placement grooves and is hingedly connected with the side arms, so that the included angle between the supporting frame and the ground can be adjusted.

[0009] The upper end position of the side arm is provided with a horizontally arranged and rotatable driving rod.

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

[0011] The outer side of the supporting block is provided with a worm gear, the side arm is inserted with a transmission rod, and the lower end of the transmission rod is provided with a worm that engages with the worm gear.

[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 engaged with a driving bevel gear.

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

[0015] Through the rotation of the driving rod, the driving tooth block moves axially, so that the clamping tooth is clamped or separated from the tooth groove, and meanwhile the driving support block is lifted or lowered;

[0016] The action of the clamping tooth moving away from the tooth groove is synchronized with the action of the support block descending.

[0017] The action of the clamping tooth moving away from the tooth groove is synchronized with the action 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 clamping tooth and the tooth groove are still clamped.

[0019] The beneficial effects of the above arrangement are: 1. The lower end of the support frame is grounded, and by swinging the support frame, the included angle between the support frame and the horizontal plane can be adjusted, thereby adjusting the height and horizontal position of the driving rod, the height and horizontal position of the connection between the gas storage tank and the support frame are also changed, achieving the purpose of adjusting the height of the gas storage tank and the included angle with the ground, so that the gas storage tank reaches the set height and reaches the horizontal position; 2. The driving rod rotates, which can simultaneously adjust the axial movement of the clamping tooth and the lifting of the support block, thus simplifying the structure of the device and reducing the cost.

[0020] The tooth groove is directly arranged on the tank body of the gas storage tank, which will cause the thickness of the tank body to be smaller and reduce its strength. Based on this, a further improvement is that: both ends of the gas storage tank are provided with two center-symmetric and same-height connecting blocks; the tooth groove is arranged on the connecting block.

[0021] The specific mounting structure of the driving rod is that: a horizontally arranged insertion hole is arranged in the side arm, and the driving rod is inserted into the insertion hole; the inner end of the driving rod is provided with an external thread column, and the outer end penetrates outwards from the side arm; the outer end of the tooth block is connected with a sleeve nut which is threadedly connected with the external thread column.

[0022] Since the tooth block is easy to rotate with the driving rod, the clamping tooth is difficult to accurately clamp the tooth groove. Based on this, a further improvement is that: a limiting groove is radially led out at the position of the external thread column; the outer side wall of the sleeve nut radially leads out a limiting block of the clamping limiting groove.

[0023] The application also provides an adjusting method of the natural gas storage tank support device, which adopts the natural gas storage tank support device, and comprises the following steps:

[0024] S1, hoist the fixedly connected natural gas storage tank support device and the gas storage tank to the target position;

[0025] S2, use the crane to fix the gas storage tank;

[0026] S3, rotate the driving rod to move the clamping tooth outward of the support frame, separate from the tooth groove, and lower the support block to separate from the gas storage tank;

[0027] S4, use the crane to move the gas storage tank to the set height and keep it horizontal;

[0028] S5, swing the support frame, under the premise of ensuring that the lower end of the support frame abuts against the ground, adjust the included angle with the horizontal plane, adjust the height of the driving rod, so that the toothed catch is opposite the tooth groove;

[0029] S6, reverse rotation of the driving rod, so that the toothed catch engages the tooth groove, so that the support block rises against the gas storage tank;

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

[0031] The beneficial effects of the present application are: 1. The lower end of the support frame is grounded, the included angle between the support frame and the horizontal plane can be adjusted by swinging the support frame, so that the height and horizontal position of the driving rod are adjusted, the height and horizontal position of the connection between the gas storage tank and the support frame are also changed, the height adjustment and the angle adjustment with the ground of the gas storage tank are achieved, and the gas storage tank reaches the set height and reaches the horizontal position; 2. The driving rod rotates, which can simultaneously adjust the axial movement of the toothed catch and the lifting of the support block, thereby simplifying the structure of the device and reducing the cost; 3. The operation of adjustment is simple and convenient. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

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

[0039] Example 1:

[0040] As Figures 1-3As shown in the drawings, the application discloses a natural gas storage tank supporting device, which comprises a supporting frame 1 for supporting a storage tank 2. The supporting frame 1 is provided with two U-shaped placing grooves 3 with openings upward, and the two sides of the placing grooves 3 are provided with side arms 101. The bottom of the placing groove 3 is provided with a supporting block 4, and the top view of the supporting block 4 is rectangular. The supporting block 4 is inserted into a rectangular groove 102 on the bottom of the placing groove 3, and the rectangular groove 102 is shaped like the supporting block 4, so as to guide the lifting of the supporting block 4. The lower end of the rectangular groove 102 is connected with a lifting groove 103, and the length of the lifting groove 103 is greater than that of the rectangular groove 102, so that the lifting groove 103 and the rectangular groove 102 form a T-shaped groove. The lower end of the supporting block 4 extends downward to form a connecting column, and a worm wheel 7 arranged in the lifting groove 103 is sleeved on the connecting column.

[0041] The storage tank 2 is located between the placing grooves 3 and is hinged to the side arms 101, so that the included angle between the supporting frame 1 and the ground can be adjusted. As shown in the drawings, Figure 4 The upper end of the side arm 101 is provided with a horizontally arranged insertion hole, and a driving rod 5 is inserted into the insertion hole. The inner end of the driving rod 5 is provided with an outer threaded column 51, and the outer end of the driving rod 5 extends outward from the side arm 101 and is rotationally connected through a bearing clamped in the insertion hole.

[0042] The inner end of the driving rod 5 is threadedly connected with a tooth block 6, and the side surface of the tooth block 6 is provided with a clamping tooth 61. The two ends of the storage tank 2 are provided with two center-symmetric and same-height connecting blocks 11, and the connecting blocks 11 are provided with tooth grooves 21 corresponding to the clamping tooth 61. When the driving rod 5 rotates, the driving tooth block 6 moves axially, and is clamped or separated from the tooth groove 21.

[0043] The insertion hole is radially led out two symmetrically arranged limiting grooves 52 at the position of the outer threaded column 51; the outer side wall of the screw sleeve 62 is radially led out a limiting block 63 clamping the limiting groove 52. The limiting block 63 clamps the limiting groove 52 to limit the tooth block 6, so as to avoid 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 rotationally connected through a bearing. The lower end of the transmission rod 8 is provided with a worm 81 engaged with the worm wheel 7. Thus, the transmission rod 8 is rotated to drive the worm wheel 7 to lift, so as to drive the supporting block 4 to lift.

[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 engaged with a driving bevel gear 10; the driving bevel gear 10 is sleeved and fixed on the driving rod 5. In this way, by rotating the driving rod 5, the driving block 6 moves axially, so that the clamping teeth 61 are clamped or separated from the tooth grooves 21, and meanwhile the supporting block 4 is lifted and lowered. Moreover, the action of the clamping teeth 61 approaching the tooth grooves 21 is synchronized with the action of the supporting block 4 being lifted, and the action of the clamping teeth 61 moving away from the tooth grooves 21 is synchronized with the action of the supporting block 4 being lowered. The length of the tooth grooves 21 is configured so that, during the process of the supporting block 4 being lifted and abutting against the gas storage tank 2, the axial movement of the clamping teeth 61 will not be blocked, and moreover the clamping teeth 61 are always clamped with the tooth grooves 21.

[0046] Compared with the prior art, the embodiment has the following beneficial effects: 1. The lower end of the supporting frame 1 is grounded, and by swinging the supporting frame 1, the included angle between the supporting frame 1 and the horizontal plane can be adjusted, so that the height and horizontal position of the driving rod 5 are adjusted, and the height and horizontal position of the connection between the gas storage tank 2 and the supporting frame 1 are also changed, so that the height adjustment and the included angle adjustment of the gas storage tank 2 are achieved, and the gas storage tank 2 reaches the set height and the horizontal position; 2. The driving rod 5 is rotated, so that the axial movement of the clamping teeth 61 and the lifting and lowering of the supporting block 4 are simultaneously adjusted, thus simplifying the structure of the device and reducing the cost.

[0047] Embodiment two:

[0048] The application also discloses an adjusting method of the natural gas storage tank 2 supporting device, and adopts the natural gas storage tank 2 supporting device, and comprises the following steps:

[0049] S1, hoist the fixedly connected natural gas storage tank 2 supporting device and the gas storage tank 2 to a target position;

[0050] S2, fix the gas storage tank 2 by using a crane;

[0051] S3, rotate the driving rod 5, so that the clamping teeth 61 move outward of the supporting frame 1, are separated from the tooth grooves 21, and the supporting block 4 is lowered and separated from the gas storage tank 2;

[0052] S4, move the gas storage tank 2 to a set height by using the crane, and keep the gas storage tank 2 horizontal;
