Description

TECHNICAL FIELD

[0001] The application belongs to the hoisting technical field, and particularly relates to a single-machine hoisting and rotating hoisting method for an ultrahigh flare tower. BACKGROUND

[0002] The ultrahigh flare tower has a guide rail frame, which is a structure for supporting and fixing the ultrahigh flare tower. Since the connecting position of the guide rail frame and the connecting position of the single-section tower are not in the same plane, the installation of the ultrahigh flare tower is difficult, and the following problems mainly exist during the installation:

[0003] 1. The ultrahigh flare tower has a relatively heavy overall weight. Compared with ordinary towers, the ultrahigh flare tower is a completely new design structure, and the tower does not have lifting lugs, so the hoisting difficulty is high, and the construction cannot be performed according to the previous hoisting experience. In addition, the information is not synchronized during the coordination of the double cranes, and the coordination difficulty is high.

[0004] 2. Due to the existence of the guide rail frame, the guide rail frame needs to be installed on the single-section tower in advance, so that the overall height of the single-section tower is increased, and the hoisting operation is easily interfered by the guide rail frame.

[0005] 3. The hoisting height of the ultrahigh flare tower is high, and is greatly affected by the wind speed. The center of gravity of the tower during hoisting is easily deviated, and the tower is easily rotated in the air, so that the lifting rope is twisted. How to avoid the influence of the wind speed is a problem that needs to be solved urgently.

[0006] 4. The tower has diagonal braces, which are easily interfered and collided with the vertical braces of the tower during hoisting. Once interference and other problems occur, the bolts cannot be quickly connected, the hoisting time of the tower in the air is increased, and the influence of the wind speed and other external factors is increased.

[0007] 5. The ultrahigh flare tower is adjacent to the sea, and the sea wind is strong, the airflow changes greatly, the hoisting time is short, and the hoisting station site has the problem of high underground water level.

[0057] Embodiment 1

[0058] The super-high flare tower of the present embodiment is a tower structure with a height of more than 160 m and a total weight of more than 2000 tons. The tower has a certain particularity, that is, the flare tower has a guide rail frame arranged from top to bottom on the flare tower for supporting and fixing the flare tower, and the height of the guide rail frame is higher than the height of the super-high flare tower, so that the overall height of the flare tower is increased.

[0059] As shown in Figure 2 , Figure 3 , the super-high flare tower of the present embodiment includes vertical supports 7 and horizontal supports 11, and inclined supports 8 are installed on the vertical supports 7 and the horizontal supports 11. Branch arms are installed between the inclined supports 8 and the horizontal supports 11 and the vertical supports 7. Specifically, the vertical supports 7, the horizontal supports 11 and the inclined supports 8 are relatively thick hollow pipe structures, and flanges are used as connecting structures for connecting the vertical supports 7, the horizontal supports 11 and the inclined supports 8. The vertical supports 7, the horizontal supports 11 and the inclined supports 8 have flanges at the fixed positions thereof, which are referred to as flange fixed points 10. Due to the large overall size of the tower, the horizontal supports 11, the inclined supports 8 and the vertical supports 7 can be installed in multiple sections. For example, the vertical supports 7 of a single-section tower can be divided into two sections, the horizontal supports 11 can be divided into two or three sections, and the inclined supports 8 can be divided into two or three sections. The vertical supports 7, the horizontal supports 11 and the inclined supports 8 have rib plates thereon, and the branch arms have connecting plates thereon. The connecting plates and the rib plates are connected together by fastening bolts, and the fixed positions thereof are referred to as connecting plate fixed points 9. In addition, there are some small connecting arms connecting the branch arms with the vertical supports 7, the horizontal supports 11 and the inclined supports 8 to form a stable frame structure.

[0060] The following terms appearing below are explained:

[0061] First section tower: the first section tower structure of the super-high flare tower, which is connected to the ground and is the foundation of the super-high flare tower.

[0062] Single section tower: in the super-high flare tower, the remaining tower structure except the first section tower will use more single section towers in the hoisting of the super-high flare tower, and the remaining tower structure except the first section tower is collectively referred to as a single section tower, and in the case of a special number of tower sections, the first N section tower is named in the prefix of the single section tower, which represents the Nth section tower structure in the super-high flare tower, for example, the fifth section tower refers to the fifth section tower structure in the super-high flare tower.

[0063] The embodiment is directed to the weight and height of the super-high flare tower, and uses the SCC20000A type 2000 tonnage crawler crane 1 to carry out hoisting operation, and divides the super-high flare tower into the first section tower for ground foundation assembly and seven section towers for ground prefabrication, and the parameters of the super-high flare tower of the embodiment are shown in the following table:

[0064]

[0065] As can be seen from the above table, in the fifth, sixth, seventh and eighth section towers, although the hoisting weight decreases, the rated load of hoisting also decreases, and as the height gradually reaches more than 100 meters, the sea wind speed is large and changes greatly, and it is necessary to hoist as soon as possible under the condition of small wind speed and shorten the hoisting time as much as possible.

[0066] In the embodiment, a single machine lifting and rotating hoisting method for a super-high flare tower is disclosed, and the embodiment uses a crane 1 to install the segmented and assembled single section towers to form a super-high tower by lifting and rotating, including the following steps:

[0067] S1, fixing the first section tower on the ground by assembly;

[0068] S2, prefabricating single section towers around the first section tower, installing guide rail frames on the single section towers, and the lower end of the guide rail frame being higher than the lower end of the single section tower;

[0069] S3, installing counterweights below the vertical supports 7;

[0070] S4, before hoisting, selecting at least three points on the single section tower to bind the leash, and binding the end of the leash to the mobile device;

[0071] S5, binding the single section tower with the binding rope 16, the binding rope 16 being connected with the lifting cover, and the lifting cover being connected with the lifting tool of the crane through the hoisting rope;

[0072] S6, hoisting the single section tower section by section, the mobile device moving to drive the single section tower to rotate and fixedly connect with the lower tower.

[0073] The crane 1 of the embodiment refers to the crane 1 for hoisting the prefabricated single-section tower, and some cranes such as the 75-ton crawler crane and the 70-ton mobile crane are used in the process of prefabricating the single-section tower and assembling the first-section tower, but these cranes do not participate in the hoisting operation of the single-section tower but are used as the moving fixed point.

[0074] In step S2, the prefabrication site of the tower needs to have sufficient space and flat ground, as shown in the figure, the embodiment arranges the tower foundation center 2 and the first prefabrication position 3, the second prefabrication position 4, the third prefabrication position 5, and the fourth prefabrication position 6 around the foundation of the crane 1, assembles the first-section tower at the tower foundation center 2, prefabricates the second-section tower and the seventh-section tower at the first prefabrication position 3, prefabricates the third-section tower and the eighth-section tower at the second prefabrication position 4, prefabricates the fourth-section tower and the sixth-section tower at the third prefabrication position 5, and prefabricates the fifth-section tower at the fourth prefabrication position 6. Figure 1

[0075] In terms of ground treatment, since the super-high torch tower is adjacent to the sea, the hoisting station site has the problem of high underground water level, the embodiment punches steel sheet piles into the ground and encloses an area, digs a pit in the area of the steel sheet piles, the pit depth is about 2.1 m, fills backfill soil into the pit and pads it to make the backfill soil higher than the ground, the overall pad height is about 1.0 m, the total treatment height is about 3.1 m, forming a foundation for the crane 1, planning the track of the mobile equipment, flattening the ground corresponding to the track of the mobile equipment, and detecting the bearing capacity of the foundation.

[0076] As shown in the figure, in terms of hoisting, the hoisting is carried out in the way of hoisting cover and binding, the binding rope 16 used in hoisting is a steel wire rope, and the steel wire rope passes through from below the cross brace 11, the diagonal brace 8, and the branch arm. Figure 4

[0077] In terms of weather selection and time planning, since the operation space has few obstacles, it is greatly affected by the sea surface wind speed, after the designated hoisting plan is determined, the hoisting time is controlled to be completed within 30-45 days, the hoisting time is not later than 10:00 am, the hoisting is carried out under the condition that the wind speed is not greater than 9.8 m / s, and the strong wind and heavy rain weather is avoided.

[0078] As an embodiment, the embodiment is installed with a winch on the mobile equipment, the end of the leash is wound on the winch, and the length of the leash released by the winch is controlled, the mobile equipment of the embodiment includes a forklift, a crawler crane, a mobile crane, and other movable machines or equipment with weight.

[0079] ​​Because the tower of the embodiment has diagonal braces 8, and the ends of the diagonal braces 8 are very close to the ends of the vertical braces 7, when hoisting, the diagonal braces 8 are prone to interfere with and collide with the vertical braces 7 of the tower, causing hoisting difficulties. Because the height is high, the previous scheme of re-hoisting the diagonal braces 8 cannot be applied to the hoisting of the tower of the embodiment.

[0080] Before hoisting, the flange fixing point 10 of the diagonal brace 8 on the tower is disconnected, the upper end of the diagonal brace 8 is tied to the cross brace 11 or the branch arm by using the upper end binding rope, the connecting plate fixing point 9 of the branch arm on the tower is disconnected, and the hinge shaft is installed on the connecting plate fixing point 9, so that the diagonal brace 8 is hingedly connected with the branch arm; the lower end of the diagonal brace 8 and the vertical brace 7 are connected together by using the lower end binding rope 12, so that the diagonal brace 8 can rotate around the hinge shaft under the action of the upper end binding rope and the lower end binding rope 12, and then the adjustment of the position of the end of the diagonal brace 8 is realized. The upper end binding rope and the hinge shaft bear the entire weight of the diagonal brace 8. By adjusting the position of the end of the diagonal brace 8, the conflict and interference of the diagonal brace 8 with the installation of the vertical brace 7 are avoided. In order to avoid manual pulling of the lower end binding rope 12 on the diagonal brace 8, in the embodiment, the lower end binding rope 12 passes through the tension adjusting device and is arranged in overlap in the tension adjusting device. The adjustment of the position of the end of the diagonal brace 8 is realized by adjusting the overlap length of the lower end binding rope 12. As an embodiment, as shown in Figure 5 、 Figure 6 The tension adjusting device of the embodiment includes a fixer 13 with two rope passing holes. The fixer 13 has a piston cylinder inside. A piston rod is movably and sealingly installed in the piston cylinder. The upper end of the piston rod is fixedly installed with a lifting roller 14. A gas inlet and outlet switch 15 is installed on the fixer 13, and the gas inlet and outlet switch 15 communicates with the piston cylinder. The lower end binding rope 12 passes through the rope passing holes in a U shape, and the lifting roller 14 presses against the lower end binding rope 12. This scheme needs to constantly open and close the gas inlet and outlet switch 15 to change the gas pressure in the piston cylinder, so that the position of the piston rod in the piston cylinder changes, the degree of extrusion of the lifting roller 14 on the lower end binding rope 12 changes, and the overlap length of the lower end binding rope 12 changes. In the implementation, the worker also needs to carry a compressed gas cylinder and a gas inlet and outlet pipe. The gas inlet and outlet pipe is inserted on the gas inlet and outlet switch 15.
