Technical Field

[0001] This invention relates to the field of transmission tower antenna installation technology, and in particular to a method for hoisting the transmission tower mast structure. Background Technology

[0002] With rapid socio-economic development, people are increasingly looking towards higher altitudes, and advancements in science and technology have provided strong support for the construction of antenna buildings. As landmarks in modern cities, antenna buildings are constantly changing the urban economic structure and landscape. However, the complex shape and structural system of antenna buildings also present significant challenges for on-site installation.

[0003] The installation of towers and masts is particularly important in antenna construction. In related technologies, tower cranes are usually used to lift the antenna segments onto the tower, and then the individual antenna segments are assembled into a tower mast by workers on the tower. However, when hoisting antenna segments onto some tall towers with small upper surface areas, there is not enough space on the upper surface of the tower to install tower cranes, which makes the hoisting of antenna segments difficult. Summary of the Invention

[0071] The following is for reference. Figures 1 to 14 The method for hoisting the launch tower mast structure of the present invention will be described in detail.

[0072] Reference Figure 8 The method for hoisting the launch tower mast structure according to an embodiment of the present invention includes the following steps:

[0073] Step S100: Install a pulley system on the tower body 100. The pulley system includes a first pulley 110 located at the upper end of the tower body 100.

[0074] Understandably, reference Figure 1 The pulley block may include a first pulley 110 and a third pulley 120. The first pulley 110 may be installed at the top of the tower body 100. A support platform may be provided in the middle of the tower body 100. The height of the support platform is the height that the tower crane can reach. The first winch 400 may be installed on the support platform. The third pulley 120 is installed on the tower body 100 and may be at the same level as the first winch 400. The third pulley 120 can guide the first wire rope 420 to the first winch 400.

[0075] Optionally, the first winch 400 can also be installed on the ground, in which case the third pulley 120 is installed on the tower body 100 and located on the ground.

[0076] Step S200: Assemble the mast 200, with a second pulley 240 installed at the top of the mast 200;

[0077] refer to Figure 1 and Figure 7 It is understood that the mast 200 includes a base 210, a truss standard section 220 and a hoisting section 230. The truss standard section 220 is installed on the upper end of the base 210, and the hoisting section 230 is installed on the upper end of the truss standard section 220. A second pulley 240 can be installed on the upper end of the hoisting section 230.

[0078] Step S300: Install the first wire rope 420 and the second wire rope 430, so that one end of the first wire rope 420 is connected to the mast 200, and the other end of the first wire rope 420 is connected to the first winch 400 via the first pulley 110, so that one end of the second wire rope 430 is connected to the second winch 410, and the other end of the second wire rope 430 extends to the ground via the second pulley 240;

[0079] refer to Figure 1 and Figure 2 It is understood that both the first winch 400 and the second winch 410 are mounted on the support structure. One end of the first wire rope 420 is connected to the first winch 400, and the other end of the first wire rope 420 can extend downwards after passing through the third pulley 120 and the first pulley 110 in sequence to connect with the mast 200. Thus, the first winch 400 can drive the mast 200 to rise or fall through the first wire rope 420. One end of the second wire rope 430 is connected to the second winch 410, and the other end of the second wire rope 430 can extend downwards through the second pulley 240 to connect with the antenna section 300. Thus, the second winch 410 can drive the antenna section 300 to rise or fall through the second wire rope 430.

[0080] Optionally, when the first winch 400 is installed on the ground, the second winch 410 can also be installed on the ground.

[0081] Step S400: Raise the mast 200 to the first preset height using the first winch 400 and the first wire rope 420;

[0082] It should be noted that, in order to ensure the stability of the mast 200, the distance by which the top of the mast 200 extends beyond the upper surface of the tower body 100 shall not exceed half the length of the mast 200 itself.

[0083] Step S500: The tower mast is hoisted to the top of the tower body 100 using the second winch 410 and the second wire rope 430.

[0084] Understandably, the mast comprises multiple antenna segments 300, which are connected sequentially from bottom to top to form the mast. During the hoisting of the mast, the antenna segments 300 can be hoisted onto the tower body 100 segment by segment using the second winch 410 and the mast 200. Each time an antenna segment 300 is hoisted, it is installed on the tower body 100. Correspondingly, the distance between the second pulley 240 of the mast 200 at the first preset height and the upper surface of the tower body 100 is greater than the height of the antenna segment 300.

[0085] Optionally, when hoisting the mast, the antenna section 300 can be assembled on the ground to form the mast, and then the mast can be hoisted onto the tower body 100 by the second winch 410 and the mast 200; correspondingly, at this time, the distance between the second pulley 240 of the mast 200 at the first preset height and the upper surface of the tower body 100 is greater than the height of the mast.

[0086] It should be noted that the tower mast includes multiple antenna segments 300, which are connected sequentially from bottom to top to form the tower mast.

[0087] According to the method for hoisting the launch tower mast structure of the present invention, firstly, a pulley block is installed on the tower body 100, the pulley block including a first pulley 110 located at the upper end of the tower body 100; then, the mast 200 is assembled, and a second pulley 240 is installed at the top of the mast 200; next, a first wire rope 420 and a second wire rope 430 are installed, one end of the first wire rope 420 is connected to the mast 200, and the other end of the first wire rope 420 is connected to a first winch 400 via the first pulley 110; one end of the second wire rope 430 is connected to a second winch 410, and the other end of the second wire rope 430 extends to the ground via the second pulley 240; then, the mast 200 can be lifted to a first preset height by the first winch 400 and the first wire rope 420; then, the tower mast is hoisted at the top of the tower body 100 by the second winch 410 and the second wire rope 430. The tower mast structure hoisting method of the present invention uses a first winch 400 to pull a first wire rope 420 to raise the mast 200 to a first preset height, and a second winch 410 to pull a second wire rope 430 to hoist the mast at the top of the tower body 100. During the hoisting process of the antenna structure of the transmission tower, the hoisting height of the antenna section 300 is determined by the lengths of the first wire rope 420 and the second wire rope 430 and the installation height of the first pulley 110 on the tower body 100, and is not affected by the height of the tower body 100 and the upper surface area of ​​the tower body 100. Therefore, the tower mast structure hoisting method of the present application can be implemented on tower bodies 100 that are high and have a small upper surface area.

[0088] refer to Figure 10 In some embodiments of the present invention, step S400 includes the following steps:

[0089] Step S410: The mast 200 and the tower 100 are connected by a limiting member, which can restrict the horizontal movement of the mast 200 relative to the tower 100.

[0090] It should be noted that the reference Figure 3 and Figure 4 There can be three limiting components, which are distributed vertically. Each limiting component is connected to the mast 200 and the tower 100 to limit the horizontal displacement of the mast 200 relative to the tower 100.

[0091] Specifically, the limiting component can be a structural clamp 150, which has a simple structure and is easy to implement.

[0092] Step S420: Install a stabilizing rope on the mast 200, with one end of the stabilizing rope connected to the mast 200 and the other end connected to the ground;

[0093] Specifically, there can be four stabilizing ropes, which can be installed at intervals around the mast 200. One end of each stabilizing rope can be connected to the middle of the mast 200, and the other end of the stabilizing rope can be connected to the ground. By installing stabilizing ropes on the mast 200, the stability of the mast 200 during the lifting process is improved.

[0094] Step S430: The first wire rope 420 is pulled by the first winch 400 to raise the mast 200 to the first preset height;

[0095] Understandably, during the hoisting of mast 200, the stabilizing rope can be extended as mast 200 is hoisted.

[0096] Step S440: Install the second support structure 140 on the tower body 100 to support the mast 200;

[0097] For details, please refer to Figure 5 The second support structure 140 can be installed on the tower body 100 and located below the mast 200. The second support structure 140 includes four second bottom-support steel wire ropes, one end of which is connected to each other, and the other end of which is connected to the tower body 100 around the perimeter via shackles. The lower surface of the mast 200 abuts against the second support structure 140. The second support structure 140, composed of four second bottom-support steel wire ropes, has a simple structure and is easy to install or disassemble.

[0098] Step S450: Remove the limiting component.

[0099] Understandably, after the limiting component is removed, the mast 200 can tilt relative to the tower 100, and the second pulley 240 on the mast 200 can tilt to the outside of the tower 100 to assist in lifting the antenna section 300.

[0100] refer to Figure 11 In some embodiments of the present invention, step S500 includes, but is not limited to, the following steps:

[0101] Step S510: The antenna section 300 is hoisted to the top of the tower body 100 by the second winch 410 and the second wire rope 430;

[0102] Step S520: Install antenna segment 300 at the top of tower body 100;

[0103] It should be noted that after the antenna segment 300 is hoisted to the top of the tower 100, the workers at the top of the tower 100 can install the antenna segment 300 at the top of the tower 100.

[0104] Step S530: The remaining antenna segment 300 is hoisted using the first winch 400, the second winch 410, and the mast 200 to complete the installation of the tower mast on the tower body 100.

[0105] Understandably, after installing an antenna segment 300 at the top of the tower 100, workers can continue to lift the remaining antenna segments 300 using the first winch 400, the second winch, and the mast 200 until all antenna segments 300 are installed at the top of the tower 100, thus completing the installation of the mast at the top of the tower 100.

[0106] refer to Figure 12 In some embodiments of the present invention, step S510 includes the following steps:

[0107] Step S511: Install the hand chain hoist 440 so that the hand chain hoist 440 connects the upper end of the mast 200 and the upper end of the tower body 100;

[0108] For details, please refer to Figure 5 The hand-operated chain hoist 440 can be connected at one end to the upper left side of the tower body 100 and at the other end to the upper left side of the mast 200. Workers at the top of the tower body 100 can adjust the distance between the upper ends of the tower body 100 and the upper ends of the mast 200 using the hand-operated chain hoist 440, thereby keeping the mast 200 vertical or tilted. The hand-operated chain hoist 440 is small in size and easy to operate.

[0109] Step S512: Adjust the hand chain hoist 440 to tilt the mast 200 so that the projection of the second pulley 240 in the vertical direction falls outside the tower body 100;

[0110] Understandably, reference Figure 5The worker at the top of the tower 100 can adjust the chain hoist 440 to increase the distance between the upper end of the mast 200 and the upper end of the tower 100, so that the mast 200 can tilt relative to the tower 100, so that the projection of the second pulley 240 at the upper end of the mast 200 in the vertical direction is away from the tower 100 and falls to the ground.

[0111] Step S513: Connect one end of the second steel wire rope 430 on the ground to the antenna section 300;

[0112] Understandably, the end of the second wire rope 430 on the ground can be connected to the upper end of the antenna section 300, so that after the second winch 410 pulls the second wire rope 430, the second wire rope 430 can drive the antenna section 300 to rise vertically.

[0113] Step S514: The second wire rope 430 is pulled by the second winch 410 to lift the antenna section 300 above the tower body 100;

[0114] Understandably, reference Figure 5 The second winch 410 can pull the second wire rope 430 to retract, and the second wire rope 430 can drive the antenna section 300 to move upward until the antenna section 300 moves above the tower body 100.

[0115] Step S515: Adjust the hand chain hoist 440 to straighten the mast 200 so that the antenna section 300 moves directly above the tower body 100;

[0116] Understandably, reference Figure 6 Workers at the top of the tower 100 can adjust the chain hoist 440 to pull the tilted mast 200 to vertical, so that the antenna section 300 connected to the second wire rope 430 can move horizontally to directly above the tower 100 with the second pulley 240.

[0117] Step S516: The second wire rope 430 is pulled by the second winch 410 to lower the antenna section 300 to the upper surface of the tower body 100.

[0118] Understandably, after the antenna segment 300 moves to directly above the tower body 100 following the second pulley 240, there is a certain height between the antenna segment 300 and the upper surface of the tower body 100. The second winch 410 pulls the second wire rope 430 so that the antenna segment 300 automatically falls onto the upper end of the tower body 100, thus eliminating the need for manual handling and saving time and effort.

[0119] refer to Figure 13 In some embodiments of the present invention, step S514 includes the following steps:

[0120] Step S514a: The second wire rope 430 is pulled by the second winch 410 to raise the antenna section 300 to a second preset height;

[0121] Specifically, the second preset height can be 0.1mm.

[0122] Step S514b: Check the stress condition of the second wire rope 430;

[0123] Step S514c: If the second wire rope 430 is under normal force, the second winch 410 continues to pull the second wire rope 430 to lift the antenna section 300 above the tower body 100.

[0124] Understandably, after raising the antenna section 300 by 0.1mm, the second steel wire rope 430 is under stress. By detecting the stress on the second steel wire rope 430 at this time, workers can promptly detect and resolve any problems with the second steel wire rope 430, thereby preventing safety issues from arising with the second steel wire rope 430 during the subsequent ascent of the antenna section 300.

[0125] refer to Figure 14 In some embodiments of the present invention, step S530 includes the following steps:

[0126] Step S531: Raise the mast 200 to a third preset height, where the third preset height is the height of the antenna segment 300 to be installed;

[0127] Step S532: Hoist the antenna segment 300 to be installed.

[0128] Understandably, after the mast 200 has hoisted one antenna segment 300, the next antenna segment 300 to be installed needs to be installed above the installed antenna segment 300. At this time, the mast 200 needs to be raised to a third preset height so that the height between the second pulley 240 and the upper surface of the installed antenna segment 300 is greater than the height of the antenna segment 300 to be installed. Then, the first winch 400 can lift the antenna segment 300 to be installed above the installed antenna segment 300 through the first wire rope 420.

[0129] refer to Figure 9 In some embodiments of the present invention, step S200 includes the following steps:

[0130] Step S210: Install the first support structure 130 on the tower body 100;

[0131] For details, please refer to Figure 1The first support structure 130 is installed on the tower body 100 and located below the mast 200. The first support structure 130 may include four first bottom-support steel wire ropes, one end of which is connected to each other, and the other end of which is connected to the tower body 100 around the perimeter via shackles. The lower surface of the mast 200 abuts against the first support structure 130. The first support structure 130, composed of four first bottom-support steel wire ropes, has a simple structure and is easy to install or disassemble.

[0132] Step S220: Install base 210 on first support structure 130;

[0133] Understandably, the base 210 is mounted on the first support structure 130.

[0134] Step S230: Install the truss standard section 220 on the base 210;

[0135] Step S240: Install the hoisting section 230 on the truss standard section 220 to assemble the mast 200 on the first support structure 130. The second pulley 240 is located at the upper end of the hoisting section 230.

[0136] It is understandable that by assembling the mast 200 in sections on the first support structure 130, the mass of the base 210, the truss standard section 220 and the hoisting section 230 is smaller than that of the mast 200 as a whole, making it easier to move. This avoids the problem of difficulty and low installation accuracy of installing the mast 200 on the first support structure 130 when the mast 200 is hoisted as a whole by a tower crane.

[0137] refer to Figure 8 In some embodiments of the present invention, the following steps are also included:

[0138] Step S600: The first wire rope 420 is pulled by the first winch 400 to lower the mast 200 to the ground;

[0139] Step S700: Recover the first wire rope 420 and the second wire rope 430, and dismantle the mast 200.

[0140] Understandably, the first winch 400 can drive the mast 200 down to the ground via the first wire rope 420. After the mast 200 is down to the ground, the worker can disconnect the connection between the first wire rope 420 and the mast 200, then retrieve the first wire rope 420 and the second wire rope 430, and then dismantle the mast 200 for use in the next hoisting of the tower mast.

[0141] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
