Description

Technical Field

[0001] This invention relates to the field of elevated equipment technology, specifically to a steel tower. Background Technology

[0002] The search revealed existing technologies with publication number CN223647505U, such as... Figure 1 As shown, a lifting motor 13 for driving the extension and retraction of each tower section is fixed on the first tower section 4, and the output end of the lifting motor 13 is connected to a second drum 14. In adjacent tower sections, upper pulleys 16 are provided on both sides of the top of the lower tower section, and lower pulleys 17 are provided on both sides of the bottom of the upper tower section. The first tower section 4 is not raised or lowered. For the raising and lowering of the second tower section 5, one end of the lifting cable 15 is fixed to the outside of the first tower section 4. The lifting cable 15 passes sequentially around the upper pulley 16 on one side of the first tower section 4, the two lower pulleys 17 of the second tower section, and the upper pulley 16 on the other side of the first tower section 4 before being wound onto the second drum 14. For the raising and lowering of the third tower section, one end of the lifting cable is fixed to the top of one side of the first tower section, then passes sequentially around the upper pulley on one side of the second tower section, the two lower pulleys of the third tower section, and the upper pulley on the other side of the second tower section before being fixed to the top of the other side of the first tower section. For the lifting and lowering of the fourth tower section, one end of the lifting cable is fixed to the top of one side of the second tower section, then sequentially passes around the upper pulley on one side of the third tower section, the two lower pulleys of the fourth tower section, and the upper pulley on the other side of the third tower section before being fixed to the top of the other side of the second tower section. When the lifting motor winds the lifting cable of the second tower section, the second tower section rises. The rising second tower section lifts the lifting cable of the third tower section, driving the third tower section to rise. The rising third tower section then lifts the lifting cable of the fourth tower section, driving the fourth tower section to rise. Therefore, except for the first tower section, all other tower sections require a lifting motor to pull the cable to achieve lifting and lowering. Although using cables allows for the lifting and lowering of each tower section, a large number of pulleys are needed between the first and second tower sections, and these pulleys must be installed at the bottom of the second tower section. To ensure the normal lifting and lowering of the second tower section, firstly, the size of the first tower section needs to be increased; secondly, due to the use of pulleys and cables for lifting and lowering, the stability between the first and second tower sections is poor.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steel tower, comprising a tower body, wherein the tower body comprises a first tower section, a second tower section, a third tower section, a fourth tower section, and a fifth tower section sequentially arranged from bottom to top and from outside to inside; a driving member on the second tower section moves on a transmission rod within the first tower section, causing the second tower section to move upward; simultaneously, the third tower section moves upward within the second tower section, the fourth tower section moves upward within the third tower section, and the fifth tower section moves upward within the fourth tower section, thereby realizing the unfolding of the tower body.

[0005] As a preferred embodiment of the present invention: a first traction rope is fixedly connected to the bottom of the fifth tower section. After the first traction rope passes over the pulley on the fourth tower section, it is fixedly connected to the bottom of the third tower section. One end of the first traction rope continues to pass over the pulley on the second tower section and is fixedly connected to the bottom of the first tower section. The bottom of the fourth tower section is fixedly connected to a second traction rope. One end of the second traction rope passes over the pulley on the third tower section and is fixedly connected to the bottom of the second tower section. The driving member at the bottom of the second tower section moves upward along the transmission rod to move the second tower section upward. While the second tower section moves upward, the first traction rope and the second traction rope cause the remaining tower sections to unfold.

[0006] As a preferred technical solution of the present invention: the inner wall surfaces of the first tower section, the second tower section, the third tower section, the fourth tower section, and the fifth tower section are all provided with sliding components, and the outer wall surfaces of the second tower section, the third tower section, the fourth tower section, and the fifth tower section are all provided with slide rails that slide in cooperation with the sliding components; the sliding component includes a mounting plate, the mounting plate moves along the outer wall surface of the slide rail by means of rollers, and the side of the mounting plate facing the tower body is also provided with a gasket.

[0007] As a preferred technical solution of the present invention: the bottom of the tower body is also provided with a falling component, and the tower body can be erected and fallen down through the falling component.

[0009] As a preferred technical solution of the present invention: the side of the mounting base is also provided with a first pin. When the tower body is laid down, the first pin is inserted into the insertion hole of the first tower section to lock the tower body on the mounting base.

[0010] As a preferred embodiment of the present invention, it further includes a movable frame, and the tower body is connected to the movable frame via the collapsing assembly.

[0011] As a preferred technical solution of the present invention: the mobile frame is further provided with a support component, and the support component supports the end of the tower body away from the collapsing component; the support component includes a support frame, the support frame contacts the tower body through a support pad, and a socket is provided on the support frame. After the plug plate on the first tower section is connected to the socket, the second pin is used to lock one end of the first tower section on the support frame.

[0012] As a preferred technical solution of the present invention: the mobile frame is also provided with a cable retractor, the top of the fifth tower section is also provided with a tower top platform, and the side of the tower top platform is also provided with a rope buckle, and the rope buckle is connected to the cable retractor by a cable.

[0013] As a preferred technical solution of the present invention: the cable on the top platform of the tower is connected to the winding device on the moving frame after passing through the guide frame provided on the tower body.

[0014] The beneficial effects of the present invention by adopting the above technical solution are as follows: Since the lifting and lowering of the second tower section is achieved by the cooperation of the driving component and the transmission rod, the lifting and lowering of the first tower section and the second tower section of the device does not require the use of steel cables. Since the lifting and lowering of the first tower section does not require the use of steel cables, the stability between the two tower sections is improved; and the size of the second tower section can be enlarged. Since the size of the second tower section can be enlarged and the two tower sections are rigidly connected, the tower base composed of the first tower section and the second tower section has stronger stability.

[0017] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0018] Please see Figure 2-16 The present invention provides an embodiment of a steel tower, comprising a tower body 3, wherein the tower body 3 comprises a first tower section 30, a second tower section 31, a third tower section 32, a fourth tower section 33, and a fifth tower section 34, which are sequentially fitted from bottom to top and from outside to inside; the second tower section 31 moves upward by means of a driving member 322 on a transmission rod 38 within the first tower section 30; while the second tower section 31 moves upward, the third tower section 32 moves upward within the second tower section 31, the fourth tower section 33 moves upward within the third tower section 32, and the fifth tower section 34 moves upward within the fourth tower section 33, thereby realizing the unfolding of the tower body 3.

[0019] Specific examples Figure 5 , Figure 6 , Figure 7 As shown, since the lifting and lowering of the second tower section 31 is achieved through the cooperation of the drive component 322 and the transmission rod 38, the first tower section 30 and the second tower section 31 do not require steel cables for lifting and lowering. The elimination of steel cables improves the stability between the two tower sections. Furthermore, since pulleys are not required inside the second tower section 31, its size can be increased. Because the size of the second tower section 31 can be increased, and the stability between the two tower sections is further enhanced by the drive component 322 and the transmission rod 38, the tower base formed by the first tower section 30 and the second tower section 31 has greater stability.

[0020] like Figure 9 and Figure 14As shown, the top of the first tower section 30 is provided with a rope seat 319, and the bottom of the remaining tower sections are all provided with rope seats 319 for installing traction ropes; the rope seat 319 at the bottom of the fifth tower section 34 is connected to the first traction rope 7, and the other end of the first traction rope 7 passes around the pulley 310 on the fourth tower section 33 and is fixedly connected to the rope seat 319 at the bottom of the third tower section 32. One end of the third traction rope 9 is connected to the rope seat 319 at the bottom of the third tower section 32, and the other end passes around the pulley 310 on the second tower section 31 and is connected to the first tower section 34. The top rope seat 319 is fixedly connected; the bottom rope seat 319 of the fourth tower section 33 is fixedly connected to the second traction rope 8; one end of the second traction rope 8 passes over the pulley 310 on the third tower section 32 and is fixedly connected to the bottom rope seat 319 of the second tower section 31; the driving member 322 at the bottom of the second tower section 31 moves upward along the transmission rod 38 to move the second tower section 31 upward, and at the same time the second tower section 31 moves upward, the first traction rope 7 and the second traction rope 8 are used to cause the remaining tower sections to unfold. Wherein: (The rest of the text appears to be unrelated and possibly machine-generated.) Figure 16 As shown, the upper surfaces of the second tower section 31 and the third tower section 32 are each equipped with four pulleys 310, which are symmetrically arranged in pairs on the corresponding tower sections; the upper surface of the fourth tower section 33 is equipped with two pulleys 310, which are also symmetrically arranged on the fourth tower section 33; each pulley 310 is equipped with a traction rope. Thus, multiple pulleys 310 connected to their corresponding traction ropes form multiple pulley transmission systems, enabling the smooth lifting and lowering of each tower section.

[0021] Based on this, when the second tower section 31 is raised, the remaining tower sections can be automatically raised under the combined action of the first traction rope 7 and the second traction rope 8. At the same time, the two traction ropes are connected to the corresponding tower sections in this way, so that except for the first tower section 30, the remaining tower sections only need to be equipped with pulleys 310 on the upper end face, and no pulleys 310 need to be installed inside. Therefore, the size of the second tower section 31, the third tower section 32, the fourth tower section 33, and the fifth tower section 34 can be enlarged. Since the size between each tower section can be enlarged, more tower sections can be installed inside the tower body 3. Based on this, compared with the prior art, the tower body 3 of this device can have more tower sections of the same size.

[0022] Combination Figure 7 , Figure 8 , Figure 9 as well as Figure 12To further enhance the stability between the tower sections, the inner walls of the first tower section 30, the second tower section 31, the third tower section 32, the fourth tower section 33, and the fifth tower section 34 are all provided with sliding components 39, and the outer walls of the second tower section 31, the third tower section 32, the fourth tower section 33, and the fifth tower section 34 are all provided with slide rails 311 that slide in cooperation with the sliding components 39. The sliding components 39 include a mounting plate 318, which moves along the outer wall of the slide rails 311 via rollers 317, and the side of the mounting plate 318 facing the tower body 3 is also provided with a gasket 314.

[0023] In summary, by using rollers 317 to slide along slide rails 311, firstly, the resistance between each tower section during lifting and lowering is reduced; secondly, by using rollers 317 to abut against slide rails 311, the gap between any two tower sections is reduced, thereby ensuring the stability between tower sections. Specifically, taking the first tower section 30 and the second tower section 31 as examples, the outer side of the main rod of the second tower section 31 is equipped with a stainless steel slide rail 311, and the inner side of the first tower section 30 is equipped with four sets of sliding components 39. The mounting plate 318 and the mounting surface are separated by shims 314. For example, increasing or decreasing the number of shims 314 can adjust the gap between the outer and inner tower sections.

[0024] Based on the above solutions, such as Figure 1 , Figure 2 As shown, the bottom of the tower body 3 is also provided with a tilting component 2, which enables the tower body 3 to be erected and lowered. Based on this, the tilting component 2 can be used to complete the erection and lowering of the tower body 3.

[0025] Combination Figure 6 and Figure 11 As shown, the collapsing assembly 2 includes a mounting base 23, on which a pivot pin seat 20 is provided. The first tower section 30 is rotatably connected to the pivot pin seat 20 via a first pivot pin 35. A lifting mechanism 22 is provided on one side of the mounting base 23. One end of the lifting mechanism 22 is pivotally connected to the mounting base 23, and the other end is pivotally connected to a second pivot pin 36 on the first tower section 30. Based on this, the lifting mechanism 22 can be used to push the tower body 3 to rotate on the pivot pin seat 20, so as to realize the standing and collapsing of the tower body 3. For example, when the lifting mechanism 22 is in a high position, it causes the tower body 3 to rotate counterclockwise so that the tower body 3 is upright; conversely, when the lifting mechanism 22 is in a low position, it causes the tower body 3 to rotate clockwise so as to realize the collapsing of the tower body 3.

[0026] Specific examples Figure 11As shown, the mounting base 23 consists of two tripods, which constrain the displacement of the tower body 3. The two tripods are welded together as a whole through a base plate to ensure the coaxiality of the tripods. The base plate is fixed on the moving frame 1. The lifting mechanism 22 is preferably an electric cylinder, symmetrically installed on both sides of the tower body 3. The specific parameters of the lifting mechanism 22 are as follows: lifting stroke 4.4M, travel speed not less than 0.6M / S, load capacity not less than 6 tons. Single cylinder thrust ≥10T; cylinder diameter: 100mm; rod diameter: 70mm; installation distance: 1528mm, extended: 2555.04mm, retracted: 1528.34mm; stroke: 1032mm; single cylinder single stroke time ≤240s; two electric cylinders, synchronization accuracy within 1mm.

[0027] See Figure 6 and Figure 11 As shown, to ensure the stability of the tower body 3 when erected, the side of the mounting base 23 is also provided with a first pin 21. When the tower body 3 is erected, the first pin 21 is inserted into the insertion hole 37 of the first tower section 30 to lock the tower body 3 onto the mounting base 23. Therefore, the stability of the tower body 3 is stronger after it is erected; wherein, the first pin 21 is preferably an electric pin, and its model is: SFG-G1-034.

[0028] In summary, the cross-section of the tower body 3 is square, and the preferred number of tower sections is five. During operation, the tilting assembly 2 elevates the tower body 3 from a horizontal state to a vertical state, driven by the drive component 322 (specifically as shown in the figure) installed at the bottom of the second tower section 31. Figure 15 As shown: It consists of a servo motor 320 and a reducer 321. The parameters of the servo motor 320 are 3.8kW power, 15N / m torque, and 2500 r / min speed. The reducer 321 is an angle reducer with a speed ratio of 25 (3000 r / min, 650N / m). The second tower section is driven to rise by a screw drive between the output end of the reducer and the transmission rod 38. During this process, the third tower section 32 to the fifth tower section 34 are simultaneously raised by the traction ropes connected between each tower section and the corresponding pulleys.

[0029] like Figure 2As shown, it also includes a movable frame 1, and the tower body 3 is connected to the movable frame 1 via the collapsing assembly 2. Based on this, the movable frame 1 can be used to move the tower body 3, and under the action of the collapsing assembly 2, the tower body 3 can automatically rise and fall. At the same time, the tower body 3, the collapsing assembly 2, and the movable frame 1 are movably connected, thus giving the equipment the advantage of modularity for easy installation and disassembly. Furthermore, the movable frame 1 facilitates the movement of the tower body 3 and the collapsing assembly 2, making the transportation of the tower body 3 easier, allowing the equipment to be quickly erected where needed. The drive component 322 moves on the transmission rod 38, achieving synchronous rising of the second tower section 31 and the remaining tower sections, thus shortening the erection time of the equipment.

[0030] In summary, the first traction rope 7, the second traction rope 8, and the third traction rope 9 are all preferably steel wire ropes; then the pulley 310 is used for transmission, resulting in relatively small overall stress; the tower section is made of round tubing welded into a truss form to reduce wind resistance and simplify the manufacturing process.

[0031] Combination Figure 3 and Figure 13 The movable frame 1 is also equipped with a support assembly 4, which supports the end of the tower body 3 away from the collapsing assembly 2. The support assembly 4 includes a support frame 40, which contacts the tower body 3 through a support pad 43. A socket 41 is also provided on the support frame 40. After the insertion plate 312 on the first tower section 30 is connected to the socket 41, a second pin 42 is used to lock one end of the first tower section 30 onto the support frame 40. The second pin 42 is preferably an electric pin, model SFG-G1-034. This is to prevent the front end of the tower body 3 from wobbling during movement due to lack of reliable fixation.

[0032] like Figure 3 and Figure 10 As shown, to further enhance the stability of the tower body 3 after deployment, the mobile frame 1 is also equipped with a cable retractor 5, and the top of the fifth tower section 34 is also equipped with a tower top platform 315. Therefore, communication equipment can be installed on the tower top platform 315. At the same time, the side of the tower top platform 315 is also equipped with a rope buckle 316, which is connected to the cable retractor 5 by a cable. Therefore, the cable can be tightened by the cable retractor 5 to enhance the stability of the tower body 3 after deployment. Among them, the cable retractor 5 is customized, and the customized parameters are as follows: this reel is suitable for 8mm diameter steel wire rope, with a length of 38 meters; this reel has an automatic cable reeling function; this reel is equipped with a stainless steel limit pin on the wheel, the pin is one-way locking, and it is locked when the line is released, and the locking direction of the pin is marked on the locking pin; reel weight: ≤180kg (excluding steel wire rope); the line release direction is diagonally upward, the line reeling is flexible and does not jam, and the turntable rotates flexibly.

[0033] In addition, the cable is preferably a windproof cable. After the tower body 3 is deployed, the windproof cable is fixed to the top of the tower body 3 from four directions. After the tower body 3 is lowered, the first pin 21 and the second pin 42 are used to lock the tower body, ensuring the reliability and safety of the operation. After the tower section is raised to the top, the corresponding telecommunications, communication or other equipment can be installed on the tower top platform to meet the functional requirements of communication, radar and other functions. In addition, after the tower body 3 is raised, in order to ensure the stability between each tower section, the tower section is designed with an overlapping design, that is, there is a certain overlap distance between any two tower sections. Specifically, from the first tower section 30 to the fifth tower section 34, the overlap distance is set to 2242mm (overlap 34%), 2522mm (overlap 37.8%), 2522mm (overlap 37.8%), and 2522mm (overlap 37.8%) respectively.

[0034] Experimental measurements showed that Tower 3 can operate normally without damage under wind conditions of gusts of level 8 (20.7 m / s) and steady winds of level 6 (13.8 m / s); when Tower 3 is in a downed state, it will not be damaged under wind conditions of level 12 (32.7 m / s). After the windproof cables are connected, the tower top sway indicators are as follows: level 3 wind (wind speed 5.4 m / s), top sway ≤ ±30 mm; level 6 wind (wind speed 13.8 m / s), top sway ≤ ±70 mm.

[0035] Furthermore, since the cable on the tower top platform 315 is connected to the reel 6 on the movable frame 1 via the guide frame 313 on the tower body 3, the reel 6 can be used to release the cable when the tower body 3 is unfolded and to reel it in when the tower body 3 is lowered. The reel 6 is preferably an electric cable reel. Its specific technical requirements are as follows: the cable reel is suitable for a single cable 35 meters long and 30 mm in diameter, with a total cable weight ≤ 50 kg; the cable reel is equipped with a local control panel and has a jog function. It has a remote control I / O interface for forward and reverse rotation; the geared motor operates at 220V with a rated power of 140W, and has a 1.5-meter long connecting cable, requiring an external power supply; the cable reel has a speed adjustment function with a stepless speed range of 0 to 30 r / min; the cable reel is equipped with a manual / electric switching device and a front-facing hand crank function; the cable reel is equipped with an automatic cable guide; the cable reel is equipped with a stainless steel limit pin and nylon Velcro for cable fixing; the cable reel weighs ≤125kg (excluding cable).

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
