Description

Technical Field

[0001] This invention belongs to the field of perforation positioning of vertical storage tanks in marine engineering, and particularly relates to a device for assisting in the positioning of a vertical tank skirt support. Background Technology

[0002] During the construction of offshore oil platforms, a large number of vertical storage tanks need to be installed. In the past, the base of the vertical tanks was a basic ring structure, which could be guided by a pry bar or a conical locating pin during drilling and positioning. However, there are also base structures with skirt supports, in which case it is difficult to achieve positioning using pry bars or locating pins.

[0003] When using a pry bar or tapered locating pin for positioning, inserting it from the top of the equipment skirt ring will restrict its movement due to the two-layer bolt hole structure. This will prevent it from properly aligning with the bolt holes on the equipment base. Furthermore, someone must be very close to the equipment to support it and prevent the pry bar from falling, which poses a safety hazard during hoisting operations.

[0004] If the positioning pin is inserted into the base of the equipment structure, and the pin cannot remain vertical, or if the swaying during hoisting knocks over the pin, the positioning work cannot be guaranteed. In the past, positioning work required a lot of manpower to support and stabilize the swaying tank. Due to its large tonnage, it is impossible to stabilize the swaying tank by manpower alone. When construction workers are in close contact with the tank during hoisting, there is a risk of injury due to their close position.

[0005] Therefore, there is an urgent need to design a hole-aligning device for positioning a vertical tank skirt support to solve the problems mentioned above. Summary of the Invention

[0006] To address the technical problem mentioned in the background art that using pry bars or positioning pins cannot keep the upright tank vertical and requires a large amount of manpower to support the swaying tank, which can cause crushing injuries, a vertical tank skirt support positioning auxiliary hole alignment device is provided to solve the problem of hole alignment between the equipment base and the vertical tank.

[0007] To achieve the above objectives, the specific technical solution of the vertical tank skirt support positioning auxiliary hole alignment device of the present invention is as follows: A device for aligning holes in a vertical tank skirt support includes a locking bolt inserted into a first bolt hole in the skirt support ring. A washer is provided between the locking bolt and the first bolt hole, and the washer abuts against the first bolt hole. A connecting nut is connected to one end of the locking bolt inserted into the first bolt hole, and a positioning screw is connected to the connecting nut. The positioning screw is connected to a conical head, and the conical head passes through a second bolt hole in the tank base and a third bolt hole in the equipment base in sequence, so that the first bolt hole, the second bolt hole, and the third bolt hole are aligned vertically.

[0008] Furthermore, multiple washers are provided along the length of the locking bolt. By changing the number of washers, the overall length of the connection between the locking bolt, connecting nut, positioning screw, and tapered head can be initially adjusted.

[0009] Furthermore, the locking bolt is inserted into one end of the first bolt hole and screwed into the connecting nut, so that the connecting nut is positioned between the skirt ring and the tank base.

[0010] Furthermore, a positioning screw is screwed to the end of the connecting nut away from the locking bolt, and the end of the positioning screw away from the connecting nut is inserted into the second bolt hole of the tank base.

[0011] Furthermore, the end of the connecting nut furthest from the locking bolt is positioned above the tank base, so that the length of the positioning screw extending beyond the connecting nut can be adjusted by rotating the positioning screw.

[0012] Furthermore, a tapered head is vertically connected to the end of the positioning screw away from the connecting nut. Rotating the positioning screw allows the tapered head to pass through the third bolt hole.

[0013] Furthermore, the locking bolt, connecting nut, positioning screw, and tapered head are connected in sequence and located in a straight line.

[0014] Furthermore, the locking bolt is screwed into the connecting nut to secure it to the first bolt hole.

[0015] The vertical tank skirt support positioning auxiliary hole alignment device of the present invention has the following advantages: The initial length of the device can be adjusted by increasing or decreasing the number of shims between the locking bolt and the first bolt hole. Based on the protrusion position of the conical head, rotating the positioning screw ensures that the conical head extends from the second bolt hole into the third bolt hole, achieving vertical alignment of the first, second, and third bolt holes. This application reduces safety risks, saves labor, reduces crane usage, and significantly improves construction efficiency. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0020] The following is a reference to the appendix. Figure 1 To be continued Figure 2 The present invention describes an auxiliary hole-aligning device for positioning a vertical tank skirt support.

[0021] like Figure 2 As shown, the vertical tank skirt support positioning auxiliary hole alignment device of the present invention includes a locking bolt 1, which is inserted into the first bolt hole 10 of the skirt support ring 7. A washer 4 is provided between the locking bolt 1 and the first bolt hole 10, and the washer 4 abuts against the first bolt hole 10. A connecting nut 2 is connected to one end of the locking bolt 1 inserted into the first bolt hole 10. A positioning screw 3 is connected to the connecting nut 2. The positioning screw 3 is connected to a conical head 5. The conical head 5 passes through the second bolt hole 11 of the tank base 8 and the third bolt hole 12 of the equipment base 9 in sequence, so that the first bolt hole 10, the second bolt hole 11 and the third bolt hole 12 are aligned in the vertical direction.

[0022] The initial length of the device can be adjusted by increasing or decreasing the number of shims 4 between the locking bolt 1 and the first bolt hole 10. Based on the extension position of the conical head 5, the positioning screw 3 can be rotated to ensure that the conical head 5 extends out along the third bolt hole 12 after being inserted from the second bolt hole 11, so that the first bolt hole 10, the second bolt hole 11 and the third bolt hole 12 are aligned in the vertical direction.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, multiple washers 4 are provided along the length of the locking bolt 1. By changing the number of washers 4, the overall length of the connection between the locking bolt 1, the connecting nut 2, the positioning screw 3 and the conical head 5 can be initially adjusted. The locking bolt 1 is inserted into the first bolt hole 10 and screwed into the connecting nut 2 so that the connecting nut 2 is positioned between the skirt ring 7 and the tank base 8.

[0024] The end of the connecting nut 2 away from the locking bolt 1 is screwed with a positioning screw 3. The end of the positioning screw 3 away from the connecting nut 2 is inserted into the second bolt hole 11 of the tank base 8. The end of the connecting nut 2 away from the locking bolt 1 is located above the tank base 8 so that the positioning screw 3 can be rotated to adjust the length of the positioning screw 3 extending out of the connecting nut 2.

[0025] In this embodiment, the tank base 8 is connected to the bottom of the side wall of the tank 6 along the circumference of the tank body 6, and a plurality of second screw holes 11 are spaced apart along the circumference of the tank base 8. Similarly, the skirt ring 7 is connected to the side wall of the tank body 6 along the circumference of the tank body 6, and the skirt ring 7 is located above the tank base 8 in the vertical direction. A plurality of first screw holes 10 are spaced apart along the circumference of the skirt ring 7, and the first bolt holes 10 are aligned with the second bolt holes 11 in the vertical direction.

[0026] The tank base 8 is abutted against the equipment base 9. Multiple third bolt holes 12 are spaced apart along the circumference of the equipment base 9. The first bolt hole 10, the second bolt hole 11 and the third bolt hole 12 are connected in sequence by connecting bolts, so that the tank 6 is stably connected to the equipment base 9. However, before the connecting bolts are connected and fixed, the third bolt hole 12 needs to be aligned with the first bolt hole 10 and the second bolt hole 11 by this device.

[0027] Preferably, multiple annular washers 4 are inserted into the locking bolt 1. By changing the number of washers 4, the overall length of the connection between the locking bolt 1, the connecting nut 2, the positioning screw 3 and the conical head 5 can be initially adjusted. The locking bolt 1 is inserted into the first bolt hole 10 and screwed into the connecting nut 2, so that the connecting nut 2 is positioned between the skirt ring 7 and the tank base 8, and can fix the washers 4, that is, abut against the top of the skirt ring 7.

[0028] A positioning screw 3 is screwed onto the end of the connecting nut 2 away from the locking bolt 1. By rotating the positioning screw 3, the length of the positioning screw 3 extending out of the connecting nut 2 is changed, so that the end of the positioning screw 3 away from the connecting nut 2 is inserted into the second bolt hole 11 of the tank base 8. Preferably, the end of the connecting nut 2 away from the locking bolt 1 is located above the tank base 8, which facilitates the adjustment of the length of the positioning screw 3 extending out of the connecting nut 2 by rotating the positioning screw 3.

[0029] Furthermore, such as Figure 1 As shown, a conical head 5 is vertically connected to the end of the positioning screw 3 away from the connecting nut 2. Rotating the positioning screw 3 allows the conical head 5 to pass through the third bolt hole 12. The locking bolt 1, connecting nut 2, positioning screw 3, and conical head 5 are connected in sequence and located in a straight line. The locking bolt 1 is screwed to the connecting nut 2 so that the locking bolt 1 is fixedly connected to the first bolt hole 10.

[0030] In this embodiment, preferably, a tapered head 5 is vertically welded to the end of the positioning screw 3 away from the connecting nut 2. When the positioning screw 3 is rotated, the tapered head 5 passes through the third bolt hole 12, thereby aligning the first bolt hole 10, the second bolt hole 11 and the third bolt hole 12 in the vertical direction.

[0031] To ensure the alignment of the first bolt hole 10, the second bolt hole 11, and the third bolt hole 12, the locking bolt 1, the connecting nut 2, the positioning screw 3, and the tapered head 5 must be connected in sequence and located on a straight line.

[0032] As a preferred embodiment, multiple auxiliary hole-aligning devices can be connected along the circumference of the skirt ring 7, the tank base 8, and the equipment base 9 to improve the alignment of bolt holes. After connecting the skirt ring 7, the tank base 8, and the equipment base 9 with connecting bolts, the auxiliary hole-aligning devices are removed, and then the bolt holes at the auxiliary hole-aligning devices are connected and fixed.

[0033] The working principle of the vertical tank skirt support positioning auxiliary hole alignment device in this invention is as follows: First, the distance between the skirt ring 7 and the equipment base 9 is initially measured, and then the number of washers 4 inserted on the locking bolt 1 is changed. Then, insert the locking bolt 1 along the first threaded hole 10, and thread the inserted end onto the connecting nut 2; Then, rotate the positioning screw 3 screwed onto the connecting nut 2 so that the tapered head 5 is inserted into the second screw hole 11; Finally, continue to rotate the positioning screw 3 so that the conical head 5 extends along the third screw hole 12, thereby aligning the first screw hole 10, the second screw hole 11, and the third screw hole 12 in the vertical direction.

[0034] Based on the vertical tank skirt support positioning auxiliary hole alignment device, this invention reduces safety risks and hazards, saves labor input, reduces crane shift input, and greatly improves construction efficiency.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
