Description

Technical Field

[0001] The present application relates to the field of power tower installation technology, and in particular to an auxiliary device and a splicing method for modular splicing of power towers. Background Art

[0002] Power towers are mainly used to support high-voltage transmission lines to ensure the safety and stability of power transmission. Traditional power towers are usually one-piece structures. Although this design performs well in terms of strength and stability, it has many inconveniences during transportation and installation, so the problems of complex installation and long construction period of power towers still exist. Currently, power towers are disassembled into multiple modular units with the same structure for production, and then spliced ​​on site, which is why the appearance of the steel structure at the height of each tower body is consistent.

[0003] Reference Figure 1 A power tower includes a tower wing and four tower legs. The tower legs are connected to the ground and are the main supporting structure of the power tower body. The tower wing is arranged in the middle part of the tower body, symmetrically distributed along the center of the tower body and extending on both sides, and is used to erect high-voltage transmission lines.

[0004] Regarding the above-mentioned related technologies, although the technical solutions of modular production and on-site splicing have improved the construction efficiency of power towers, a large amount of manpower and material resources are still required in the on-site splicing process. The assembly is completed by using tower cranes and large lifting vehicles, and welders climbing to the preset height to manually operate the welding. Summary of the invention

[0005] In order to improve the on-site splicing efficiency of power towers and shorten the construction period of power towers, the present invention provides an auxiliary device and a splicing method for modular splicing of power towers.

[0006] On the one hand, the present invention provides an auxiliary device for modular splicing of power towers, which adopts the following technical solution: An auxiliary device and a splicing method for modular splicing of a power tower, comprising: A conveying rod is vertically arranged between a plurality of tower legs, a lifting driving member is arranged on the conveying rod, the length of the conveying rod body is greater than the height of the tower legs, and the conveying rod is composed of a plurality of rod body sections spliced ​​together; A conveying ring plate is horizontally arranged, sleeved, and vertically slidably connected to the conveying rod body, and a fixing piece is arranged on the conveying ring plate to fix each tower body module; the conveying ring plate is connected to the lifting drive piece; The annular support structure is sleeved on the bottom end of each tower leg and connects the tower legs. The annular support structure supports the tower legs in multiple directions.

[0007] By adopting the above technical solution, a conveying rod is installed between the tower legs, and the lifting drive member on the conveying rod body is used to assist in conveying the tower body module. By taking advantage of the position of the conveying rod in the middle of the four tower legs, other functions besides conveying can be realized; due to the necessity of structural installation, the height of the conveying rod needs to be higher than the height of the tower legs to ensure the installation of the topmost tower body module; The conveying ring plate is driven by the lifting drive member on the conveying rod, slides vertically along the rod body of the conveying rod, and then drives the fixing member on it to slide vertically, which is the specific structural basis for realizing the modular splicing of the tower body; During the process of transporting the tower body module by the above-mentioned conveying rod, the annular support structure realizes a multi-directional support effect at the bottom of the tower leg; after the on-site splicing process of the power tower begins, with the installation of the first tower body module, the two tower body parts are tilted, and the multi-sided support effect of the annular support structure is used to fix the tower legs in a tilted state at a preset angle when the tower body module is installed, thereby playing a supporting role.

[0008] Optionally, also include: An elastic member, one end of which is hinged and horizontally slidably connected to the inner wall of the annular support structure, the elastic member rotates in a vertical plane around the hinged end, and a plurality of elastic members are horizontally distributed on the annular support structure; The support plate is hinged to an end of the elastic member close to the tower leg, and the support plate rotates vertically around the hinged portion.

[0009] By adopting the above technical solution, the main part of the tower leg is made of steel, which is a steel rod structure with a relatively high vertical height. Therefore, the support member used to support the bottom end is selected as an elastic member, and the elastic force of the tower leg is applied to buffer the gravity when the tower leg is tilted to avoid hard contact; based on this, a support plate is set at the abutment part of the elastic member and the tower leg, and the support plate surface is used to increase the contact area of ​​the tower leg, thereby improving the support stability; In addition, the elastic force needs to be kept in action during the tilting of the tower legs. Therefore, the hinged action of the elastic piece enables the elastic piece on the tower body to change its angle in the vertical plane. During the tilting of the tower legs, the gas spring is compressed and the angle changes at the same time, giving way to the tower leg structure. Considering the horizontal component of gravity when a single steel rod is tilted, a single large gas spring can be used to achieve this.

[0010] Optionally, a plurality of the annular support structures are vertically distributed, and a foot tube is provided on the outer walls of the plurality of the annular support structures, and the foot tube is sleeved on the plurality of the annular support structures.

[0011] By adopting the above technical solution, the foot tube is a tube wall structure that accommodates the annular support structure. During the on-site splicing of the power tower, the relevant components supporting the bottom of the tower leg are accommodated in the foot tube. During the fixing and welding stage after the power tower is spliced, the technicians fill the foot tube with cement to directly complete the pouring and fixing of the bottom of the tower leg, which improves the splicing efficiency of the power tower to a certain extent. In practical applications, a foot tube with a preset diameter can be set outside the foot tube to cast cement piers with a preset diameter, or the foot tube can be set to a preset width for direct casting.

[0012] Optionally, the lifting drive member includes: A frame wheel, with a vertical wheel surface, is arranged at the top of the conveying rod, and is distributed at equal angles in the circumferential direction; A winch is arranged at the bottom end of the conveying rod and is arranged one by one corresponding to the frame wheel. A steel rope is wound around the winch, one end of the steel rope is wound around the frame wheel and connected to the conveying ring plate.

[0013] By adopting the above technical solution, one end of the steel rope is pulled by the hoist, and the other end is connected to the conveying ring plate through the guidance of the frame wheel. Therefore, the hoist rolls the steel rope to lift the conveying ring plate, and the hoist rolls the steel rope in the opposite direction to lower the conveying ring plate, so that the conveying ring plate descends along the conveying rod; Under the pull of the steel rope, the conveying rod plays a guiding role to stabilize the lifting process of the conveying ring plate; the frame wheels are symmetrically distributed along the middle part of the conveying rod body, so that the conveying ring plate is evenly stressed and kept level during the lifting process; The above scheme utilizes the pulley principle to use the frame wheel as a fixed pulley. The technical solution of using a steel rope to pull and lift the conveying ring plate is suitable for work environments with a high working height difference. There is no need to install other lifting components. The welding of the tower module can be fully realized by cooperating with technicians who climb to the preset height.

[0014] Optionally, also include: The mounting rod is horizontally formed at the top of the conveying ring plate, the length direction of which is parallel to the radial direction of the conveying ring plate and radially extends away from the center of the conveying ring plate. The mounting rods are distributed one by one corresponding to the part between each two tower legs, and a sliding groove is provided at the bottom end of the mounting rod body; The frame plate, the rod body part is vertically arranged, the top end is slidably connected to the slide groove, and the fixing member is arranged on the frame plate.

[0015] By adopting the above technical solution, the mounting rod is the main conveying support structure of the conveying ring plate. The technicians install the tower body module on the fixing parts of the frame plate. The bottom wall of the mounting rod is provided with a slide groove, so that the slider slides in the slide groove, and the slider slides in the slide groove to drive the frame plate to slide. After the conveying ring plate rises to a preset height, the tower body module is pushed toward the tower wall of the power tower to keep the tower body module flush with the edge of the tower body, which is convenient for technicians to weld.

[0016] Optionally, the bottom end of the frame plate is horizontally arranged, and the bottom end of the frame plate extends in a direction away from the center of the conveying ring plate in the radial direction of the conveying ring plate, and the fixing member is arranged at a horizontal part of the bottom end of the frame plate.

[0017] By adopting the above technical solution, the radial extension of the conveying ring plate can make the fixing piece of the above frame plate extend to the tower wall part between the two tower legs after the frame plate slides to the end of the mounting rod, thereby ensuring the sliding effect; In addition, during the on-site splicing of the power tower, the installation rods on multiple sides of the conveying ring plate convey the tower module at the same time, or only one side of the installation rod conveys the tower module. No matter which conveying method is used, it is impossible to avoid the scene of unbalanced weight of the conveying ring plate. Therefore, the horizontally arranged frame plate can facilitate the installation of the counterweight block to balance the conveying ring plate so that the conveying ring plate remains parallel. In traditional solutions, tower modules are usually transported by hoisting, and the tower modules are tied to lifting equipment such as tower cranes and cranes. During the lifting process, the entire module is in a free swinging state, and it is easy to collide with the tower structure when approaching the power tower, causing damage. Therefore, the above solution uses a frame plate with a clamping effect instead of traditional hoisting to improve stability.

[0018] Optionally, the horizontal portion of the bottom end of the frame plate is vertically slidably connected to the frame plate rod body.

[0019] By adopting the above technical solution, the frame body is used as a fixed part, and the horizontal part at the bottom of the frame body slides vertically so that the frame body plays a clamping role similar to that of a clamping claw. The top part of the frame body can be horizontally provided with a fixed part and the vertical sliding part at the bottom horizontal part to shorten the distance and realize clamping; Therefore, when the technicians fix the tower module on the frame body, the horizontal molding part at the bottom of the frame body moves upward and cooperates with the horizontal part at the top of the frame body to clamp the tower module between the two. It should be added that overly precise components should not be installed during on-site splicing of power towers. The assembly modules of large steel poles have high splicing stress, and precise components can be easily damaged during the transportation of steel pole splicing modules.

[0020] On the other hand, the present invention provides a modular splicing method for a power tower using the following technical solution: A method for splicing an auxiliary device for modular splicing of an electric power tower, comprising the following steps: Splicing and erecting the conveying rod, splicing four tower legs at a preset position, installing a winch and the conveying ring plate, fixing the conveying rod and four tower legs, so that the conveying rod and the tower legs remain in a vertical state; Prepare a tower module between two tower legs, install the corresponding tower module on the fixing member, set up a ladder, and climb to a preset height; Tilt the two tower legs to a preset angle with the ground, fit the two sides of the tower module, and weld them; Keep the tower legs in an inclined state; transport and weld the remaining tower modules between the two tower legs in sequence; Repeat the above process for the two tower legs on the opposite sides of the two tower legs to complete the installation of tower body modules on the two parallel side edges of the tower body; Guide the opposite side walls of the two tower bodies to tilt toward each other to a preset angle, fix them, and repeat the conveying process of the conveying rod to complete the installation of the remaining tower body modules; Fix the elastic parts and pour cement into the foot tube.

[0021] By adopting the above steps, the tower modules are installed sequentially. This is a basic solution for transporting using a transport rod. Furthermore, the tower legs can be installed in groups using the symmetrical distribution structure of the transport ring plate on the transport rod. The traditional splicing of power towers requires the tower modules to be hoisted and installed in sequence, and only one tower module can be transported at a time. If the above solution is adopted, the tower modules can be installed in groups at the same time. Specifically, the tower modules are grouped, and the two opposite surfaces formed by the four tower legs are divided into two groups. The symmetrical distribution structure on the conveying ring plate is used to simultaneously convey the tower modules on the opposite side walls of the two power towers to achieve symmetrical installation. The simultaneous installation of the two sides of the power tower can greatly save the installation period of the power tower. Alternatively, the four side walls of the power tower can be installed simultaneously by using the sliding guides of the four installation rods on the conveying ring plate, further improving the installation efficiency and allowing the conveying rods to fully play their role as auxiliary devices.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The lifting drive on the conveying rod realizes the precise vertical movement of the conveying ring plate through the winch and the frame wheel, ensuring that each tower module is spliced ​​at the specified height, thus improving the accuracy and reliability of module splicing; 2. The annular support structure supports the tower legs in multiple directions, enhancing the stability of the bottom of the tower legs, effectively preventing the tower legs from tilting or shifting during construction, and improving the safety and reliability of construction.

[0031] The following is combined with Figure 2-7 This application is described in further detail.

[0032] The present application embodiment discloses a tower module of an electric power tower, referring to Figure 2 and Figure 3 A tower module of an electric power tower includes a plurality of steel poles distributed in a plane to form a steel frame structure. The steel frame structure is a modular structure within a preset height section of each side wall of the electric power tower 1. The steel frame structures at different heights have the same appearance and similar structure, and the difference lies in the different widths. During field splicing, the steel frames of each height section of the tower wall of each electric power tower 1 are spliced ​​in sequence and stacked to form the electric power tower 1; in addition to forming the above-mentioned steel frame structure, the steel poles can also form a steel frame structure, which is the tower wing 12 part of the electric power tower 1, spliced ​​at a preset height to erect high-voltage transmission lines.

[0033] Secondly, the embodiment of the present application discloses an auxiliary device for modular splicing of an electric power tower, which is used to assist technicians in sequentially splicing the tower body modules 13 of the electric power tower 1 onto the tower legs 11, thereby assisting in completing the on-site splicing and assembly process of the electric power tower 1. Figure 3 and Figure 4 An auxiliary device for modular splicing of an electric power tower 1 includes two main parts, a conveying rod 2 and a foot tube 3. The conveying rod 2 is vertically arranged between multiple tower legs 11 to assist in the installation of vertically distributed tower modules 13; the foot tube 3 is used to support the bottom end of the tower leg 11 and plays a supporting role during the splicing process of the electric power tower 1.

[0034] Reference Figure 4 and Figure 5The rod body of the conveying rod 2 is too high, and is manufactured in multiple sections, which are spliced ​​on the spot. The top part of the spliced ​​conveying rod 2 is formed with a horizontally arranged metal plate, which is a rectangular plate. Two ends of the metal plate in the length direction are rotatably connected with two vertically arranged frame wheels 21, and steel ropes are wound on the frame wheels 21. The frame wheels 21 are used to guide the steel ropes. The two frame wheels 21 are arranged in a vertical plane, so that the four sections of steel ropes on both sides of the two frame wheels 21 are all in a vertical plane; the metal plate body is vertically penetrated with grooves corresponding to the steel ropes, for the rope body of the steel rope to pass through and extend downward. A winch 23 is set one by one at the bottom of the tower corresponding to each frame wheel 21, and a steel rope is connected to the winch 23. Therefore, one end of the steel rope is driven by the winch 23 and guided by the frame wheel 21, and the other end rises and falls with the retraction and release of the winch 23.

[0035] Reference Figure 4 and Figure 6 The central part of the rod body of the conveying rod 2 is slidably connected with a horizontally arranged conveying ring plate 24, and the conveying ring plate 24 slides vertically along the rod body part of the conveying rod 2. Specifically, the conveying ring plate 24 is an annular plate with a circular groove in the middle part of the plate body, and the diameter of the circular groove in the middle part is adapted to the diameter of the rod body of the conveying rod 2. The central part of the plate surface of the conveying ring plate 24 is connected with the above-mentioned steel rope; the steel rope is rolled by the winch 23, and under the guidance of the frame wheel 21, the steel rope drives the conveying ring plate 24 to rise and fall; it should be noted that the above-mentioned groove diameter is adapted to the diameter of the conveying rod 2, indicating that the groove wall and the rod body of the conveying rod 2 are spaced by a preset distance. The two steel ropes have a total of four sections, and the two sections of steel ropes close to the conveying rod 2 are penetrated with grooves, so that the grooves can be used as a guiding structure for the conveying ring plate 24 and can also be used to guide the steel ropes.

[0036] Reference Figure 4 and Figure 6, a plurality of mounting rods are evenly spaced on the edge of the bottom wall of the conveying ring plate 24, the length direction of the mounting rods is parallel to the radial direction of the conveying ring plate 24, and the length of the mounting rods is greater than the radius of the conveying ring plate 24 so that one end of the mounting rods protrudes from the surface of the conveying ring plate 24. A slide groove is provided on the bottom side of the mounting rod along its length direction, and both ends of the slide groove extend to both ends of the mounting groove, so that the mounting rod is in a groove shape as a whole, and a screw rod is rotatably connected in the slide groove, and the axial direction of the screw rod is parallel to the opening direction of the slide groove, that is, the length direction of the mounting rod, and a slider is threadedly connected and penetrated on the screw rod, which is a traditional screw rod slider transmission structure. In actual applications, a micro motor needs to be installed to drive the screw rod to rotate; the size of the slider is adapted to the size of the screw rod groove, and the rotation of the screw rod drives the slider to slide along the screw rod groove, that is, slide along the radial direction of the conveying ring plate 24. Since one end of the mounting rod protrudes from the conveying ring plate 24, the slider can be driven to extend to the part outside the surface of the conveying ring plate 24 through the rotation of the screw rod. A vertically arranged frame plate 243 is fixedly connected to the bottom end of the slider, a vertically arranged hydraulic cylinder is fixedly connected to the bottom end of the frame plate 243, a cylinder body of the hydraulic cylinder is fixedly connected to the bottom end of the frame plate 243, a piston rod of the hydraulic cylinder is vertically downward, a horizontally arranged bottom plate 242 is fixedly connected to the end of the piston rod, one end of the bottom plate 242 is fixedly connected to the bottom end of the piston rod, in order to maintain the horizontal state of the conveying ring plate 24, a guide groove is vertically opened on the main body of the frame plate 243, an inclined guide plate is formed on the top end of the bottom plate 242, a slider matched with the guide groove is arranged on the top end of the guide plate, the u slider is a T-shaped block, embedded in the guide groove, so that the guide plate realizes a triangular support structure, and the support bottom plate 242 remains horizontal. Driven by the screw rod and the hydraulic cylinder, the bottom plate 242 can simultaneously achieve vertical and horizontal displacements, and can be used as a more sophisticated auxiliary mounting part. Specifically, the technicians install the tower module 13 on the bottom plate 242, and the conveying ring plate 24 can be conveyed to a preset height under the operation of the winch 23. The sliding of the bottom plate 242 in two directions conveys the tower module 13 to the edge of the tower wall. Of course, the stable conveying of the tower module 13 cannot be completed by only one bottom plate 242. Therefore, in this embodiment, a horizontally arranged metal plate is fixed (or integrally formed) on the top of the frame plate 243, and the hydraulic cylinder drives the bottom plate 242 to move vertically. The bottom plate 242 and the above-mentioned metal plate form a clamping structure for clamping the tower module 13.

[0037] In general, according to the technical effects of the conveying rod 2, the bottom plate 242 and the installation rod, the length direction of the installation rod should correspond to the multi-side walls of the tower body, that is, the axial direction of each installation rod corresponds to the middle part between the two tower legs 11.

[0038] Reference Figure 4 and Figure 7The foot tube 3 is in the shape of a tube. This embodiment does not limit the shape of the foot tube 3. A cylindrical tube is used as an example. An annular support structure is provided inside the foot tube 3. The annular support structure is evenly spaced in multiple groups along the vertical direction of the foot tube 3. Each group of annular support structures is horizontally distributed, including a slide groove provided on the inner wall of the foot tube 3 and a slider slidably connected to the inside of the annular groove 31; the annular groove 31 is horizontally, circumferentially, and angularly distributed along the inner wall of the foot tube 3. The shape of the slider is adapted to the annular groove 31 and slides along the annular groove 31; in order to limit the slider and prevent the slider from escaping from the annular groove 31, the cross-section of the annular groove 31 is T-shaped, and the slider slidably connected to the inside of the annular groove 31 is clamped by the relative edges of the groove wall. A pneumatic push rod or a gas spring 32 is hinged on one side of the multiple sliders of each group of annular support structures close to the center of the foot tube 3, preferably Select the gas spring 32, the hinge axis is horizontal, perpendicular to the radial direction of the foot tube 3, so that the gas spring 32 rotates in the vertical plane along the hinge axis, the piston rod end of the gas spring 32 is hinged with a support plate 33, the support plate 33 plate surface is a straight surface, and it is horizontally arranged with the hinge axis of the gas spring 32, so that the support plate 33 rotates vertically around the hinge axis; thus, each group of annular support structures includes multiple gas springs 32 and support plates 33 distributed horizontally, and multiple groups of annular support structures are distributed vertically to form multiple circles of support structures around the tower wall, and the support plate 33 plate surface abuts against the tower leg 11 to support the tower leg 11. It should be noted that in this embodiment, the annular support structure and the foot tube 3 are integrally formed, and in actual applications, the annular support structure can be a separate annular groove 31 structure installed inside the foot tube 3, and the technicians can freely choose according to the longevity of the foot tube 3 and the actual situation.

[0039] The implementation principle of the auxiliary device for modular splicing of power towers in the embodiment of the present application is as follows: a conveying rod 2 is arranged between multiple tower legs 11, and multiple installation rods are symmetrically and circumferentially distributed on the rod body, and tower modules 13 with multiple side edges are conveyed at the same time, so that the tower modules 13 with symmetrical side walls can be installed at the same time, which greatly improves the installation efficiency; During installation, the tower leg 11 becomes inclined as the tower body module 13 is installed, and the support plate 33 at the bottom increases the support area between the tower leg 11 and the bottom. The hinged structure of the support plate 33 keeps the inclined tower leg 11 supported and stable.

[0040] Accordingly, the embodiment of the present application discloses a method for using an auxiliary device for modular splicing of a power tower, which is applied to the splicing of a power tower 1 with the assistance of the auxiliary device. A method for modular splicing of a power tower 1 comprises the following steps: The technicians splice and erect the conveying rod 2 at the preset soil body and install the conveying ring plate 24 at the same time, build the foot tube 3 at the installation position corresponding to the tower leg 11 (if an annular support structure is provided, the annular support structure is installed at the same time), and check whether the gas spring 32 and the winch 23 are working normally; The technicians straighten the delivery rod 2 and the tower leg 11 and keep them in a vertical state; The technicians install the tower module 13 transported to the installation site on the bottom plate 242 and the frame plate 243, and control the hydraulic cylinder to drive the bottom plate 242 to move upward to clamp the tower module 13; the technicians install another tower module 13 in the same placement manner on the bottom plate 242 at the bottom of another mounting rod opposite to the above mounting rod, and according to the above steps, simultaneously realize the stable clamping of the tower modules 13 on the two opposite sides; The hoist 23 operates to drive the conveying ring plate 24 to move up to the top of the tower leg 11; at the same time, the installation personnel set up a ladder and climb to the preset height; the installation is carried out from the top of the tower to the bottom of the tower and from top to bottom; After the installation personnel and the conveying ring plate 24 reach the preset height, the screw on the installation rod rotates to drive the frame plate 243, the bottom plate 242 and the stably clamped tower body module 13 to be conveyed to the part between the two tower legs 11 until they are flush with the plane formed by the two tower legs 11; The technicians on the ground use special tools to apply force to the tower legs 11, so that the two tower legs 11 are tilted to a preset angle with the ground, adapted to the tilt angles on both sides of the tower module 13, so that the tower legs 11 fit the edges of both sides of the tower module 13, and the installers weld the tower legs 11 and the tower module 13; After the tower leg 11 is tilted, the technician changes the tilt angle of the gas spring 32 and the support plate 33, and abuts the surface of the support plate 33 to maintain the tilt state of the tower leg 11; Repeat the above process to sequentially transport and weld the remaining tower modules 13 on the opposite sides of the two power towers 1; and complete the installation of the tower modules 13 on the other two opposite sides of the tower; Fix the elastic piece and pour cement into the foot tube 3.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
