The reliability of the connection mode is poor, for example, the magic tape is easy to loosen when the wind power tower is hoisted, so that the vortex strips are loosened, even a plurality of vortex strips are mutually wound, and great potential safety hazards exist.
2. Punching holes at two ends of the wind power tower barrel, enabling two ends of the turbulence bars to penetrate into the holes at two ends of the wind power tower barrel respectively, knotting any one end of the turbulence bars, and preventing the ends of the turbulence bars from being separated from the corresponding holes by using knots. The connection mode needs to punch holes at a plurality of positions on the wind power tower, the more the number of the holes is, the more the damage to the structural performance of the wind power tower is, and secondly, the local position of the wind power tower, such as the bottom end, does not have a good punching foundation, and extra thickening treatment is often needed, so that the process is complex and the cost is high.

Referring to fig. 1 to 6, the present application provides a method for installing a spoiler of a tower type building, comprising:
s1: the two ends of the building body 1 to be constructed are respectively provided with a spoiler positioning part, and the first end of the spoiler 2 is connected with an auxiliary rope 3; the spoiler positioning part at least one end of the building body 1 to be constructed is a rope limiting part for sliding and shuttling of the spoiler 2 and the auxiliary rope 3;
s2: locking the second end of the spoiler 2 to a spoiler positioning part at one end of the building body 1 to be constructed;
s3: the spoiler 2 is pulled towards the rope limiting part at the other end of the building body 1 to be constructed, so that the spoiler 2 is wound on the building body 1 to be constructed, and the rope limiting part is arranged at the first end of the spoiler 2 and the auxiliary rope 3 in a sliding penetrating manner;

S6: releasing the locking state of any one of the spoiler 2 and the auxiliary rope 3 and the corresponding spoiler positioning part;
s7: the auxiliary rope 3 and the spoiler 2 are pulled and removed from the surface of the building body 1 to be constructed.
According to the method for installing the vortex bars of the tower-type building, the lifting construction of the building body 1 to be constructed can be realized according to the S1-S7, for example, the building body 1 to be constructed can refer to a wind turbine generator tower, and the wind turbine generator tower can be safely and reliably lifted at a designated position vertically according to the S1-S7 of the method for installing the vortex bars of the tower-type building.
The method for installing the vortex bars of the tower type building mainly comprises the following steps: the method comprises three processes of setting a turbulence device, hoisting a building body 1 to be constructed and dismantling the turbulence device. In this embodiment, the spoiler is provided corresponding to S1 to S4, the hoisting of the building body 1 to be constructed corresponds to S5, and the demolishing of the spoiler corresponds to S6. In this embodiment, the spoiler device may include a spoiler 2, an auxiliary rope 3 and a spoiler positioning portion, where the spoiler 2 is wound around the building to be constructed 1, so as to play a spoiler role, avoid resonance phenomena such as vortex-induced vibration generated in the lifting process of the building to be constructed 1, and the spoiler positioning portion is disposed on the building to be constructed 1, so that the spoiler 2 is positioned on the building to be constructed 1, and a connection relationship between the spoiler 2 and the building to be constructed 1 is ensured, and the spoiler 2 is connected with the auxiliary rope 3 for installing the spoiler 2, so that a certain degree of spoiler role can be played.
When the spoiler 2, the auxiliary rope 3, the spoiler positioning part and other parts are arranged according to the S1-S4 of the spoiler installation method of the tower type building, provided by the application:
Firstly, a spoiler positioning part is arranged on a building body 1 to be constructed, and an auxiliary rope 3 is arranged on a spoiler 2, for example, the building body 1 to be constructed is a wind turbine tower, more than two spoiler positioning parts can be respectively arranged at two ends of the wind turbine tower, the spoiler positioning part at least at one end of the wind turbine tower is a rope limiting part, and the spoiler 2 can slide in the rope limiting part to shuttle; at the same time, the adjacent ends of both the auxiliary rope 3 and the spoiler 2 are connected together, for example, the first end of the spoiler 2 is connected to one of the ends of the auxiliary rope 3, and the spoiler 2 is extended by the auxiliary rope 3.
Secondly, connecting the spoiler 2 with the building 1 to be constructed, so that the second end of the spoiler 2 is locked at the spoiler positioning part at one end of the building 1 to be constructed, for example, arranging a rope knot between the second end of the spoiler 2 and the spoiler positioning part at one end of the wind turbine generator system tower, and tightly connecting the second end of the spoiler 2 with the spoiler positioning part.
Then, positioning and installing the spoiler 2 and the auxiliary rope 3 between two ends of the building body 1 to be constructed, for example, dragging the spoiler 2 and the auxiliary rope 3 between spoiler positioning parts at two ends of the wind turbine tower so that two ends of any one of the spoiler 2 and the auxiliary rope 3 are respectively connected with the spoiler positioning parts at two ends of the wind turbine tower; the spoiler 2 and the auxiliary rope 3 are usually required to be stretched between spoiler positioning parts at two ends of the wind turbine tower. Assuming that two ends of the wind turbine tower are an end A and an end B of the wind turbine tower respectively, the turbulence bar 2 is pulled to an end B of the wind turbine tower from the end A of the wind turbine tower, the auxiliary rope 3 is pulled to an end A of the wind turbine tower from the end B of the wind turbine tower, wherein the second end of the turbulence bar 2 is locked at the end A of the wind turbine tower, the first end of the turbulence bar 2 and the adjacent end of the auxiliary rope 3 are slidably positioned at the end B of the wind turbine tower, the other end of the auxiliary rope 3 is locked at the end A of the wind turbine tower, the turbulence bar 2 is wound around the wind turbine tower and is tightly stretched between the end A and the end B of the wind turbine tower, and the auxiliary rope 3 is tightly stretched between the end A and the end B of the wind turbine tower. Therefore, the first end of the spoiler 2, which is originally locked at the end B of the wind turbine tower, can be indirectly locked at the end A of the wind turbine tower through the auxiliary rope 3 by utilizing the auxiliary rope 3, so that the two ends of the spoiler 2 are positioned and installed through the end A of the wind turbine tower, and the spoiler 2 does not need to be locked at the end B of the wind turbine tower. Of course, the above operation can also ensure that the spoiler 2 is wound between the end a and the end B of the wind turbine tower according to a preset path.
According to the S5 method for installing the turbulence bars of the tower-type building, when the building body 1 to be constructed is hoisted, the wind turbine generator tower can be hoisted by using equipment such as a crane, and the angle and the position of the wind turbine generator tower are changed, for example, the wind turbine generator tower which is originally transversely arranged at a construction site is vertically suspended in the air. When the wind turbine tower is hoisted to wait for the construction of the building body 1, vortex-induced vibration caused by wind on the surface of the wind turbine tower can be overcome because the surface of the wind turbine tower is provided with the vortex-induced strips 2 and the auxiliary ropes 3, so that the damage to the wind turbine tower is avoided. Before hoisting, the wind turbine generator tower is transversely arranged on a construction site, and constructors can easily and conveniently arrange a spoiler positioning part, a connecting spoiler positioning part, a spoiler 2 and an auxiliary rope 3 on the wind turbine generator tower; the wind turbine generator tower is vertically suspended in the air after being hoisted, and the spoiler bars 2 and the auxiliary ropes 3 are vertically distributed along with the wind turbine generator tower and are attached to the periphery of the wind turbine generator tower.
According to the S6 of the method for installing the spoiler of the tower-type building, when the spoiler 2, the auxiliary rope 3, the spoiler positioning part and other parts are removed, as the connection relation between the spoiler 2 and the building 1 to be constructed is adjusted, an operator only needs to move to one end of the building 1 to be constructed to execute the removing operation, in other words, does not need to move to one end of the building 1 to be constructed, where a rope limiting part is arranged, to execute the removing operation, in other words, after the locking state of the spoiler 2 and the auxiliary rope 3 and the spoiler positioning part at one end of the building 1 to be constructed is released, the operator only needs to pull the spoiler 2 and the auxiliary rope 3, so that the spoiler 2 and the auxiliary rope 3 can be separated from the rope limiting part at the other end of the building 1 to be constructed. Taking a to-be-constructed building 1 as a wind turbine tower, wherein the wind turbine tower is provided with an end A and an end B, the end A of the wind turbine tower is often provided with an operation platform for operators to move, operators can easily lock or unlock the spoiler 2 and the auxiliary rope 3 on the operation platform, so that the spoiler 2 and the auxiliary rope 3 are locked or unlocked with a spoiler positioning part of the end A of the wind turbine tower, otherwise, the end B of the wind turbine tower is not provided with the operation platform for operators to move, after the wind turbine tower is hoisted, the end B of the wind turbine tower is often in suspension distribution, operators can hardly reach the end B of the wind turbine tower, not to mention the end B of the wind turbine tower is locked or unlocked, and therefore, a rope limiting piece is arranged at the end B of the wind turbine tower, and based on the connection relation of the spoiler 2, the auxiliary rope 3 and the rope limiting piece, the auxiliary rope 3 are in a dead weight action under the action after unlocking the locking state of the spoiler 2 and the spoiler positioning part of the end A of the wind turbine tower, the auxiliary rope 3 can be separated from the end B of the wind turbine tower, and the auxiliary rope 3 can be separated from the auxiliary rope 3 at the position of the end B of the wind turbine tower, so that the auxiliary rope 3 can be separated from the wind turbine tower 2.
In summary, the method for installing the spoiler of the tower-type building provided by the application adjusts the original connection relation between the spoiler 2 and the building 1 to be constructed by utilizing the auxiliary rope 3 and the rope limiting piece, only ensures that one end of the spoiler 2 is locked on the building 1 to be constructed, and the other end of the spoiler 2 is limited to be positioned on the building 1 to be constructed in a sliding way, thereby ensuring the winding state and the positioning effect of the spoiler 2 between the two ends of the building 1 to be constructed, avoiding that the two ends of the spoiler 2 are locked on the building 1 to be constructed, and being beneficial to simplifying the disassembly difficulty of the spoiler 2 and the building 1 to be constructed.
The method for installing the spoiler of the tower-type building provided by the application is further described below with reference to the accompanying drawings and the embodiments.
Referring to fig. 1 to 5 and 7, in some embodiments, the steps of reversely pulling the auxiliary rope 3 specifically include:
The auxiliary rope 3 is reversely pulled along the shortest connecting line path of the spoiler positioning parts at the two ends of the building body 1 to be constructed.
It can be seen that, in the above embodiment, S4 of the method for installing a spoiler of a tower-type building provided by the present application includes:
The auxiliary rope 3 is reversely pulled along the shortest connecting line path of the spoiler positioning parts at the two ends of the building body 1 to be constructed, and the auxiliary rope 3 is locked at the spoiler positioning parts, so that the second ends of the auxiliary rope 3 and the spoiler 2 are locked at the same end of the building body 1 to be constructed.
When the construction is performed according to the above S4, the spoiler 2 is wound around and tightly stretched between the spoiler positioning portions at the two ends of the building 1 to be constructed, and the auxiliary rope 3 is stretched and tightened along the shortest connecting line path of the spoiler positioning portions at the two ends of the building 1 to be constructed. The turbulence strip 2 can reliably and effectively play a role in turbulence, so that resonance phenomena such as vortex-induced vibration and the like generated in the hoisting process of the building 1 to be constructed are avoided, the auxiliary rope 3 can be rapidly and efficiently positioned on the building 1 to be constructed, in addition, after the locking relation between the auxiliary rope 3 and the building 1 to be constructed is relieved, the auxiliary rope 3 can be ensured to droop under the action of the dead weight, and the auxiliary rope 3 drooping is convenient for operators to pull.
Taking a wind turbine tower with a truncated cone-shaped structure 1 as an example, two ends of the wind turbine tower are provided with a plurality of spoiler positioning parts, at least two spoiler positioning parts are distributed in pairs, and the spoiler positioning parts are arranged at two ends of the wind turbine tower and are positioned on the same bus of the wind turbine tower. When the auxiliary rope 3 is arranged between the two ends of the wind turbine tower, the two ends of the same auxiliary rope 3 can be respectively arranged on the pair of turbulent flow strip positioning parts, so that the auxiliary rope 3 stretches along the bus of the wind turbine tower and stretches between the two ends of the wind turbine tower, and obviously, the auxiliary rope 3 also extends and distributes along the length direction of the wind turbine tower.
In some embodiments, the step of providing the spoiler positioning portions at two ends of the building body 1 to be constructed includes:
a through hole 4 is formed in one end of the building body 1 to be constructed, a closed ring body is arranged at the other end of the building body 1 to be constructed, and the through hole 4 and the closed ring body are used as a spoiler positioning part; wherein, the closed ring body is a rope limiting part.
It can be seen that, in the above embodiment, the method for installing a spoiler of a tower-type building provided by the present application includes:
A through hole 4 is formed in one end of the building body 1 to be constructed, a closed ring body is arranged at the other end of the building body 1 to be constructed, the through hole 4 and the closed ring body are used as a spoiler positioning part, and an auxiliary rope 3 is connected to the first end of the spoiler 2; the closed ring body is a rope limiting piece which can enable the spoiler 2 and the auxiliary rope 3 to slide and shuttle. The embodiment is particularly suitable for the wind turbine generator towers which are widely applied to the current market, and has good open pore foundation because the wall thickness of the tower top of the wind turbine generator tower is relatively large.
In the above embodiment, the through hole 4 and the closed loop are respectively arranged at two ends of the building body 1 to be constructed, and two ends of the spoiler 2 and the auxiliary rope 3 are respectively connected with the through hole 4 and the closed loop; one end of the spoiler 2 is locked to the through hole 4, the other end of the spoiler 2 is slidably inserted through the closed loop, one end of the auxiliary rope 3 is slidably inserted through the closed loop, and the other end of the auxiliary rope 3 is locked to the through hole 4.
Taking the spoiler 2 as an example, when locking the spoiler 2 and the through hole 4, the end of the spoiler 2 can be inserted into the building 1 to be constructed from the through hole 4, then a knot is arranged at the end of the spoiler 2, and the spoiler 2 is prevented from being pulled out from the through hole 4 by the knot. In particular, when the connected spoiler 2 and the auxiliary rope 3 are inserted into different through holes 4 at the same end of the building 1 to be constructed, the spoiler 2 and the auxiliary rope 3 can be connected integrally in the building 1 to be constructed, for example, the spoiler 2 and the auxiliary rope 3 can be bound and connected.
According to the embodiment, the closed ring body is used as the rope limiting part, the closed ring body can be used for the vortex bar 2 and the auxiliary rope 3 to shuttle, the vortex bar 2 and the auxiliary rope 3 can be pulled out from the closed ring body conveniently, meanwhile, the closed ring body can also be used for winding and positioning the vortex bar 2 and the auxiliary rope 3, the first end of the vortex bar 2 and one end of the auxiliary rope 3 are positioned at the end part of the building 1 to be constructed, and the winding requirement of the vortex bar 2 between two ends of the building 1 to be constructed and the tensioning and positioning requirement of the auxiliary rope 3 between two ends of the building 1 to be constructed are met.
In some embodiments, the step of fixedly installing the closed loop on the other end of the building body 1 to be constructed specifically includes:
and welding a semicircular ring 5 at the other end of the building body 1 to be constructed to serve as a semicircular ring 5 to serve as a closed ring body.
Accordingly, the method for installing the spoiler of the tower-type building provided by the application comprises the following steps:
A through hole 4 is formed in one end of the building body 1 to be constructed, a semicircular ring 5 is welded to the other end of the building body 1 to be constructed, and an auxiliary rope 3 is connected to the first end of the spoiler 2; the through holes 4 and the closed ring body are used as the spoiler positioning parts, wherein the semicircular ring 5 is a rope limiting part for sliding and shuttling of the spoiler 2 and the auxiliary rope 3. The semicircular ring 5 is easy to set and smooth in surface, can restrict the spoiler 2 and the auxiliary rope 3, and can also guide the spoiler 2 and the auxiliary rope 3 to be separated from the building body 1 to be constructed safely and smoothly.
In the above S1, the surface of the semicircular ring 5 should be smooth and flat, so as to reduce the abrasion to the spoiler 2 and the auxiliary rope 3, and ensure that the spoiler 2 and the auxiliary rope 3 slide smoothly in the semicircular ring 5.
In some embodiments, S2 specifically includes:
and binding the second end of the spoiler 2 to the through hole 4.
In general, when the second end of the spoiler 2 and the through hole 4 are bound, the rope of the spoiler 2 is tied in the building 1 to be constructed, that is, the second end of the spoiler 2 can be penetrated and knotted from outside to inside from the inside of the through hole 4.
On the basis of the above embodiment, the step of locking the auxiliary rope 3 to the spoiler positioning portion to lock the second ends of the auxiliary rope 3 and the spoiler 2 to the same end of the building 1 to be constructed specifically includes:
the auxiliary rope 3 and the second end of the corresponding spoiler 2 are bound into a whole.
It can be seen that, in the construction according to the above embodiment of the present application, the first end of the spoiler 2 is engaged with one end of the auxiliary rope 3, for example, the first end of the spoiler 2 is tied to the adjacent end of the auxiliary rope 3, and the second end of the spoiler 2 is tied to the other end of the auxiliary rope 3. In this embodiment, the aforementioned spoiler 2 and the auxiliary rope 3 are joined end to form a loop, and at the same time, the two connection points of the spoiler 2 and the auxiliary rope 3 are respectively constrained by the through hole 4 and the closed loop, so that it is ensured that both the spoiler 2 and the auxiliary rope 3 can be tightened between the two ends of the building 1 to be constructed.
When connecting the spoiler 2 and the auxiliary rope 3, besides binding and connecting the spoiler 2 and the auxiliary rope 3, common connecting pieces such as rope connecting fasteners can be used for connecting the spoiler 2 and the auxiliary rope 3. For example, the step of attaching the auxiliary rope 3 at the first end of the spoiler 2 may specifically include:
Rope connecting fasteners are respectively arranged at the first end of the spoiler 2 and one end of the auxiliary rope 3;
Rope connecting fasteners for fastening the spoiler 2 and the auxiliary rope 3.
It can be seen that, in the above embodiment, the spoiler 2 and the auxiliary rope 3 may be connected by other manners than binding, for example, by using rope connecting fasteners, and this connecting manner is particularly suitable for the spoiler 2 and the auxiliary rope 3 which are not easy to tie, so that the installation effect of the spoiler 2 on the building 1 to be constructed is not affected due to weak tying. The rope connecting fastener can be specifically set to be a connecting piece with high reliability such as a mountain climbing fastener.
In addition, referring to fig. 1 to 5 and 8, in some embodiments, the method for installing a spoiler of a tower-type building provided by the present application further includes the steps of:
a cable rope 6 is connected to the first end of the spoiler 2;
meanwhile, S7 may include:
the cable wind rope 6 and/or the auxiliary rope 3 are pulled downwards to disengage the spoiler 2 and the auxiliary rope 3 from the building body 1 to be constructed.
In the above described embodiment, the first end of the spoiler 2 is connected not only to the auxiliary rope 3 but also to the guy rope 6. The auxiliary rope 3 is tightly stretched between two ends of the building body 1 to be constructed and is used for realizing the positioning requirement of the spoiler 2 between the two ends of the building body 1 to be constructed; one end of the cable rope 6 is connected with the spoiler 2, and the other end of the cable rope 6 can naturally droop or be connected to a designated position of a construction site, so that constructors can conveniently pull the spoiler 2 and the auxiliary rope 3 by means of the cable rope 6, and the influence on subsequent operation due to the fact that the unlocked auxiliary rope 3 does not automatically droop according to the assumption is avoided.
It can be seen that, in the above embodiment, after the locking relationship between the auxiliary rope 3 and the corresponding spoiler positioning portion is released, if the auxiliary rope 3 is automatically separated from the building 1 to be constructed and sags, the constructor can directly pull the auxiliary rope 3, and unwind the spoiler 2 wound on the building 1 to be constructed by using the auxiliary rope 3, and if the auxiliary rope 3 cannot be completely separated from the building 1 to be constructed and sags as desired, for example, when the auxiliary rope 3 is wound and blocked at the rope limiting member and cannot automatically sag, the constructor can pull the cable 6, and apply force to the spoiler 2 and the auxiliary rope 3 by using the cable 6, so that the spoiler 2 and the auxiliary rope 3 are separated from the building 1 to be constructed.
Furthermore, the provision of the guy wires 6 also enables flexible adjustment of the relationship between the length of the auxiliary wires 3 and the installation height of the building body 1 to be constructed. For example, when the installation height of the building body 1 to be constructed is not greater than the length of the auxiliary rope 3, the auxiliary rope 3 which is separated from the building body 1 to be constructed and automatically sags can hang near the ground, so that the constructor can drag conveniently, but when the installation height of the building body 1 to be constructed is significantly greater than the length of the auxiliary rope 3, even if the auxiliary rope 3 can be separated from the building body 1 to be constructed and automatically sags, the bottom end of the auxiliary rope 3 can hang at a relatively high position, so that the constructor is difficult to touch, and for this reason, the constructor can be assisted by using the cable rope 6 which has a length significantly greater than that of the auxiliary rope 3.
Referring to fig. 4, in general, a plurality of spoiler bars 2 may be provided around a building body 1 to be constructed. Based on the foregoing arrangement, the steps of respectively providing the spoiler positioning portions at the two ends of the building body 1 to be constructed and connecting the auxiliary rope 3 at the first end of the spoiler 2 may include:
A plurality of groups of spoiler positioning parts are respectively arranged at two ends of a building body 1 to be constructed, and auxiliary ropes 3 are connected at first ends of a plurality of spoiler 2 in one-to-one correspondence; the number of groups of all the spoiler positioning portions is not smaller than the number of all the spoiler 2.
In the above embodiment, the number of groups of all the spoiler positioning portions is not smaller than the number of spoiler 2, so that each spoiler 2 can be mounted between the two ends of the building 1 to be constructed by the spoiler positioning portions. In general, the number of groups of all spoiler positioning portions is equal to the number of all spoiler 2, for example, the building 1 to be constructed is specifically a wind turbine tower, the wind turbine tower is provided with three groups of spoiler positioning portions, two spoiler positioning portions of each group of spoiler positioning portions are arranged at two ends of the wind turbine tower, and three spoiler 2 are wound and stretched between two ends of the wind turbine tower through the three groups of spoiler positioning portions in a one-to-one correspondence manner.
The above description focuses on S1 of the above embodiment, and as to S2 to S7 of the above embodiment, adaptation may be performed according to S1, for example, S2 to S7 of the above embodiment may respectively include:
S2: locking the second ends of all the spoiler strips 2 to the corresponding spoiler strip positioning parts at one end of the building body 1 to be constructed;
s3: pulling all the turbulence bars 2 towards the rope limiting parts at the other end of the building body 1 to be constructed, enabling any one turbulence bar 2 to be wound on the building body 1 to be constructed, and enabling the first end of any one turbulence bar 2 and the connected auxiliary rope 3 to slide and penetrate through the corresponding rope limiting parts;
s4: reversely dragging all auxiliary ropes 3, and locking all auxiliary ropes 3 on a spoiler positioning part, so that the second ends of any auxiliary rope 3 and the connected spoiler 2 are locked on the same end of the building 1 to be constructed;
s5: hoisting the building body 1 to be constructed, so that the second ends of all the spoiler strips 2 face upwards and the first ends face downwards;
S6: releasing the locking state of any one of all the spoiler strips 2 and all the auxiliary ropes 3 and the corresponding spoiler strip positioning parts;
S7: all the auxiliary ropes 3 and all the spoiler bars 2 are pulled away from the surface of the building body 1 to be constructed.
In the above embodiment, the number of the spoiler bars 2 and the number of the auxiliary ropes 3 may be set in a targeted manner according to the shape and size of the building 1 to be constructed, and typically, three or more spoiler bars 2 may be disposed on the circumferential side of one wind turbine tower, and three or more auxiliary ropes 3 may be disposed correspondingly.
In conclusion, the vortex-induced vibration problem of the tower-type building during hoisting of the wind turbine tower can be solved by using the vortex-induced vibration strips 2, and the safety and construction quality of the installation operation of the wind turbine tower are ensured. The method for installing the spoiler of the tower type building can not only ensure that the spoiler 2 does not fall off in the hoisting process of the wind turbine tower, but also reduce the structural change of the wind turbine tower, so that the method has the advantages of high reliability, low cost and the like.
