The method for storing by using the large-size spiral heat transfer pipe storing and transferring device comprises the following steps:
the first step is as follows: the second corresponding hole 401 on the cross beam support 4 corresponds to the cross beam support fixing hole 302 on the transfer cross beam 3, and the cross beam support 4 is fixedly connected to the adjacent transfer cross beam 3 through a fastener, so that the transfer cross beam 3 is ensured to support the spiral heat transfer pipe 6, and simultaneously, the large-diameter spiral heat transfer pipe has the surface contact with the lower part of the transfer cross beam 3 as much as possible, and the spiral heat transfer pipe 6 is prevented from turning out of the bracket in the transportation process. As shown in fig. 1 and 2, the transfer cross member 3 is disposed at the front and rear ends outside the spiral heat transfer pipe 6 in the axial direction.
The second step is that: as shown in fig. 1 and 2, the open-range distance of the second positioning holes 401 on the beam support 4 is calculated according to equation 1, and when the pitch diameter of the spiral heat transfer pipe is 750mm, the diameter of the transfer beam is selected to be 30mm, and at this time, the open-range distance of the second positioning holes 401 is 670mm, which is about 0.89 times.
The third step: connect the die-pin support on each transport crossbeam, specifically do: the second support fixing hole 501 of the support rod support 5 corresponds to the support rod support positioning hole 801 of the rotary connecting piece 8 and is connected through a bolt, then the hollow part of the hollow cylinder 806 is sleeved on the periphery of the transfer beam 3, the transfer beam positioning hole 802 of the hollow cylinder 806 corresponds to the first support fixing hole 301 on the transfer beam 3 and is fixedly connected through a screw, and if the two hole positions do not correspond, the hollow cylinder 806 can be rotated until the hole positions correspond.
The fourth step: after the support rod supports 5 are in butt joint with the transfer cross beam 3 through the rotary connecting piece 8, the two support rod supports 5 are crossed to form a triangular support, the height of a third positioning hole 502 in the support rod supports 5 is calculated according to the formula 2, and a proper positioning hole combination is selected through rotating the support rod supports. When the diameter of the spiral pipe is 750mm, the diameter of the transfer beam is selected to be 30mm, and the height of the third positioning hole 502 with respect to the circumferential top surface of the transfer beam 3 according to the above formula 2 is 577.5mm, which is about 0.77 times.
The fourth step: after being overlapped, the third positioning holes 502 selected on each supporting rod bracket 5 are matched with the end part of the supporting rod 7 and then are screwed and locked through a fastening piece, so that the supporting rod 7 is just supported at the top of the inner ring of the spiral heat transfer pipe 6 and supports each spiral of the spiral heat transfer pipe 6, and the function of stabilizing the diameter and the thread pitch of the spiral is achieved.
When the trolley assembly needs to be used for moving, as shown in fig. 1, the trolley assembly is firstly assembled, the base fixing holes 303 of the two transfer cross beams 3 correspond to the base supporting fixing holes 105 on the transverse square tube 101 in the base 1, and the transfer cross beams 3 are fixedly connected with the base 1 through fasteners. The vertical square pipes 102 of two adjacent bases 1 are corresponding to the first positioning holes 201 of the base support 2 through the base support fixing holes 105, and then the base support 2 is locked on the two adjacent bases 1 through bolts and nuts. Therefore, the butt joint of the bracket component with the spiral heat transfer pipe 6 and the trolley component is realized, wherein the opening distance of the base support 2 and the two adjacent bases 1 is consistent with the opening distance between the transfer cross beams 3.
When meeting an area with a complex terrain, the whole spiral heat transfer pipe 6 can be transferred by hanging the crane on the base 1.
When the pipes need to be stored, the bracket component, including the spiral pipe, is placed on the door-shaped material frame to play a role of orderly storing. The method of storing the small diameter spiral heat transfer tubes, and the plurality of spiral heat transfer tubes is the same as the method of storing the large diameter spiral heat transfer tubes.

the fourth step: calculating the height of a positioning hole on the support rod bracket relative to the transfer cross beam, rotating the support rod bracket to enable adjacent support rod brackets to be crossed and enabling the positioning holes on the support rod brackets to be superposed; the height of the positioning hole on the towing rod support relative to the transfer cross beam is 0.759-0.769 times of the spiral diameter of the spiral heat transfer pipe;
the fourth step: the supporting rod extends into the bolt heat transfer pipe along the positioning hole on the overlapped supporting frame of the towing rod.
