Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a non-destructive tower column climbing operation platform for inclined variable cross-section towers. Background Technology

[0002] Modern urban construction demands increasingly sophisticated architectural designs, leading to more innovative bridge tower shapes. To meet the requirements for ultra-high performance and distinctive aesthetics, the materials used in the main towers require higher performance, thus increasing construction complexity. Ultra-high inclined variable cross-section main towers are typically steel-concrete composite structures. During construction, the steel tower is hoisted in sections and then assembled and welded sequentially. The steel tower material is high-performance steel, requiring extremely high precision in welding processes and quality. Furthermore, defects in the tower structure significantly impact its load-bearing capacity. Currently, there is no suitable climbing platform for steel tower installation, concrete pouring, cable installation, and subsequent tower finishing work, and the construction process is prone to damage. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a non-destructive tower column climbing operation platform for inclined variable cross-section tower body, which solves the technical problem that there is no suitable climbing platform for the construction of inclined variable cross-section main tower of bridge in the prior art.

[0004] This invention discloses a non-destructive tower column climbing operation platform for inclined variable cross-section towers, comprising:

[0005] An upper platform for mounting on a tower column includes an upper telescopic ring, multiple bottom beams fixed to the outside of the upper telescopic ring and extending outward, and multiple first electromagnetic foot plugs for pressing against the tower column and fixed at intervals to the inside of the upper telescopic ring. The upper telescopic ring is formed by hinged ends of multiple upper telescopic beams, and a platform plate is laid on the multiple bottom beams. A lower support frame for mounting on the tower column includes a lower telescopic ring and multiple second electromagnetic foot plugs for pressing against the tower column and fixed at intervals to the inside of the lower telescopic ring. The lower telescopic ring is formed by hinged ends of multiple lower telescopic beams. An inclined rod is hinged between the upper telescopic ring and the lower telescopic ring. The inclined rod is a telescopic rod and its length direction is consistent with the axial direction of the tower column.

[0006] The further improvement of the inclined variable cross-section tower body non-destructive tower column climbing operation platform of the present invention is that the number of the inclined rods is three, and the three inclined rods are arranged in a triangular shape.

[0007] A further improvement of the inclined variable cross-section tower body non-destructive tower column climbing operation platform of the present invention is that one of the three inclined rods is a main inclined rod, and an inverted U-shaped first limiting rod is obliquely strung across the main inclined rod. The web of the first limiting rod is hung on the main inclined rod, and the two side rods of the first limiting rod are respectively located on both sides of the tower column and hinged to the lower telescopic beam.

[0008] The present invention further improves the inclined variable cross-section tower body non-destructive tower column climbing operation platform by providing an inverted U-shaped second limiting rod across the main inclined rod. The main inclined rod extends out of the upper telescopic ring and forms an extension section. The web of the second limiting rod is hung on the extension section. The two side rods of the second limiting rod are located on both sides of the tower column and are hinged to the upper telescopic beam.

[0009] The present invention further improves the inclined variable cross-section tower body non-destructive tower column climbing operation platform in that the two side rods of the first limiting rod are both male and female rods, and a telescopic oil pump is fixed between the male rod and the female rod of the male and female rods.

[0010] A further improvement of the tilted variable cross-section tower body non-destructive tower column climbing operation platform of the present invention is that the telescopic oil pump is equipped with a check valve.

[0011] A further improvement of the tilted variable cross-section tower body non-destructive tower column climbing operation platform of the present invention is that multiple third electromagnetic foot plugs for pressing the tower column are fixed at intervals on the inner side of the main inclined rod.

[0012] The present invention further improves the inclined variable cross-section tower body non-destructive tower column climbing operation platform in that the first electromagnetic foot plug and the second electromagnetic foot plug both include an electromagnetic device, a telescopic screw hinged to one side of the electromagnetic device, and a rubber pad fixed to the other side of the electromagnetic device. The telescopic screw is fixed to the upper telescopic beam or the lower telescopic beam.

[0013] The present invention further improves the inclined variable cross-section tower body non-destructive tower column climbing operation platform in that a control box is fixed on the platform plate, and the telescopic oil pump, the first electromagnetic foot plug, and the second electromagnetic foot plug are all electrically connected to the control box.

[0014] Compared with existing technologies, the advantages of this invention are positive and significant. This invention solves the technical problem of the lack of a suitable climbing platform for the construction of inclined, variable-section main towers of bridges by combining an adjustable-diameter lower support frame with an upper platform. This invention achieves the vertical climbing and circumferential retraction of the entire platform through a control box and electrical switches. During retraction, the platform surface remains level, ensuring safety and reliability without damaging the steel tower, thus enabling decorative construction operations on the steel tower and demonstrating high practicality.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-4As shown, the present invention provides a non-destructive tower column climbing operation platform for inclined variable cross-section tower bodies, comprising: an upper platform 2 for being fitted onto the tower column 1, the upper platform 2 including an upper telescopic ring 201, multiple bottom beams 202 fixed to the outside of the upper telescopic ring 201 and extending outward, and multiple first electromagnetic foot plugs 205 for pressing against the tower column 1 and being fixed at intervals to the inside of the upper telescopic ring 201, the upper telescopic ring 201 being formed by hinged ends of multiple upper telescopic beams, and the multiple bottom beams 202... A platform plate 204 is laid on top of the tower column 1; a lower support frame 3 is used to fit onto the tower column 1. The lower support frame 3 includes a lower telescopic ring 301 and multiple second electromagnetic foot plugs 302 for pressing against the tower column 1 and fixed at intervals to the inner side of the lower telescopic ring 301. The lower telescopic ring 301 is formed by hinged ends of multiple lower telescopic beams; diagonal rods are hinged between the upper telescopic ring 201 and the lower telescopic ring 301. These diagonal rods are all telescopic rods and their length direction is consistent with the axial direction of the tower column 1. In this embodiment, the tower column 1 is made of steel structure and is an inclined polygonal column with a cross-sectional area that gradually decreases from bottom to top. Both the upper telescopic ring 201 and the lower telescopic ring 301 are set in an octagonal shape. As the platform climbs and the cross-section of the tower column 1 becomes smaller, the circumferential oil pumps on the upper and lower telescopic beams can be controlled to contract, thereby successively reducing the length of each side of the octagonal cross-section and achieving the purpose of shrinking the cross-section. This invention ensures the stable climbing and descending of the climbing work platform through dual control of the telescopic oil pumps 9 of the upper and lower telescopic beams and electromagnetic control.

[0025] Preferably, there are three diagonal braces, and the three diagonal braces are arranged in a triangular shape. The stable triangular structure makes the entire climbing work platform more stable and less prone to deformation, which can limit the downward sliding and lateral tilting of the entire work platform.

[0026] Preferred, such as Figure 2 and Figure 3 As shown, one of the three inclined rods is a main inclined rod 4. A first limiting rod 7, shaped like an inverted U, is diagonally spanned across the main inclined rod 4. The web of the first limiting rod 7 is hung on the main inclined rod 4. The two side rods of the first limiting rod 7 are located on both sides of the tower column 1 and hinged to the lower telescopic beam. Further, the web of the first limiting rod 7 is hung on the main inclined rod 4, and the web of the first limiting rod 7 is higher than its two ends. A stop block 402 is fixed on the main inclined rod 4 for the first limiting rod 7 to be hung on. In this embodiment, the first limiting rod 7 improves the stability of the lower support frame. The stop block 402 is fixed below and close to the upper platform 2. The middle position of the first limiting rod 7 is located at the angle between the stop block 402 and the main inclined rod 4, ensuring that the first limiting rod 7 does not deform.

[0027] Preferably, a second limiting rod 6 in an inverted U-shape is obliquely spanned across the main inclined rod 4. The main inclined rod 4 extends from the upper telescopic ring 201, and an extension section of the web of the second limiting rod 6 is attached to this extension section. The two side rods of the second limiting rod 6 are located on both sides of the tower column 1 and hinged to the upper telescopic beam. A stop block 402 is fixed on the main inclined rod 4 for attaching the second limiting rod 6, thereby limiting the second limiting rod 6 and ensuring stable lifting and lowering of the upper platform 2. The other two inclined rods also extend from the upper telescopic ring 201, forming extension sections, which allow them to extend simultaneously during the lifting of the climbing work platform and retract simultaneously during the lowering of the climbing work platform, maintaining the horizontal stability of the upper platform 2 and preventing tilting.

[0028] Preferably, both side rods of the first limiting rod 7 and the second limiting rod 6 are male and female rods, and a telescopic oil pump 9 is fixed between the male rod and the female rod. The male rod of the male and female rod is an I-beam, and the female rod is a square sleeve fitted over two adjacent I-beams. Mounting rods are fixed on the I-beams and the square sleeves respectively. The telescopic oil pump 9 is fixed between the mounting rods of the I-beams and the square sleeves, thereby realizing the telescopic movement of the first limiting rod 6.

[0029] Furthermore, both the main diagonal rod 4 and the auxiliary diagonal rod 5 are mother-daughter rods, with a telescopic oil pump 9 fixed between the daughter rod and the mother rod. The daughter rod is an I-beam, and the mother rod is a square sleeve fitted over two adjacent I-beams. Mounting rods are fixed to both the I-beams and the square sleeves. The telescopic oil pump 9 is fixed between the mounting rods of the I-beams and the square sleeves, thereby enabling the extension and retraction of the first limiting rod 7 or the second limiting rod 6. The hinge point between the main diagonal rod 4 and the upper telescopic beam is the hinge between the square sleeve of the main diagonal rod 4 and the I-beam of the upper telescopic beam. The auxiliary diagonal rod 5 is hinged to the upper telescopic beam in the same way. The hinge point between the main diagonal rod 4 and the lower telescopic beam is the hinge between the I-beam of the main diagonal rod 4 and the I-beam of the upper telescopic beam. The hinge is achieved by opening holes at the contact points and connecting a pin between the two holes, thus realizing a rotational connection. The telescopic oil pumps 9 on the main inclined rod 4 and the auxiliary inclined rod 5 are both installed above the upper platform 2 to control the up and down movement of the entire working platform.

[0030] Specifically, such as Figures 3-5As shown, both the upper and lower telescopic beams are mother-and-child rods, with a telescopic oil pump 9 fixed between the child and mother rods. The upper telescopic beams are connected by overlapping to form an upper telescopic ring, and the lower telescopic beams are connected by overlapping to form a lower telescopic ring. Taking the lower telescopic ring 301 as an example, the first end of each lower telescopic beam overlaps above the adjacent telescopic beam, and the second end overlaps below the adjacent telescopic beam, thus forming a mutually supporting ring, providing mutual support between the lower telescopic beams. The telescopic oil pump 9 adjusts the planar size of the upper platform 2 and the lower support frame 3. The child rod of the mother-and-child rod is an I-beam, and the mother rod is a square sleeve fitted over two adjacent I-beams. Mounting rods are fixed to the I-beams and the square sleeves, respectively. The telescopic oil pump 9 is fixed between the mounting rods of the I-beams and the square sleeves, thereby realizing the telescopic movement of the upper and lower telescopic beams. The hinge position between the first limiting rod 7 and the upper telescopic beam is that the square sleeves of the two rods are hinged to each other. The hinge position between the second limiting rod 6 and the lower telescopic beam is that the square sleeves of the two rods are hinged to each other. The hinge is achieved by making holes at the contact positions and connecting the two holes with a pin, thereby realizing a rotational connection.

[0031] Preferably, the telescopic oil pump 9 is equipped with a check valve to prevent oil leakage or pressure loss.

[0032] Preferably, the inner side of the main inclined rod 4 is fixed with a plurality of third electromagnetic foot plugs 401 for pressing against the tower column 1, thereby providing an anti-slip force in the axial direction of the tower column 1. Furthermore, a plurality of third electromagnetic foot plugs 401 can also be fixed at intervals on the inner side of the two auxiliary inclined rods 5 to enhance the adsorption force for adsorption and fixation to the tower column 1.

[0033] Preferred, such as Figure 3 and Figure 6 As shown, the first electromagnetic foot plug 205, the second electromagnetic foot plug 302, and the third electromagnetic foot plug 401 each include an electromagnetic device 11, a telescopic screw 10 hinged to one side of the electromagnetic device 11, and a rubber pad 12 fixed to the other side of the electromagnetic device 11. The telescopic screw 10 is fixed to the upper telescopic beam, the lower telescopic beam, or the main inclined rod 4. Further, a mounting base can be fixed on the upper or lower telescopic beam for fixing the telescopic screw 10. The telescopic screw 10 uses an existing electric mechanism to achieve electric control of telescopic movement. The structure of the telescopic screw 10 can be a threaded rod with an externally threaded sleeve. The telescopic screw 10 can finely adjust the small gap after the platform is tightened as a whole. The hinge point hinged to the electromagnetic device 11 can rotate up and down to accommodate the angle between the outer surface of the steel tower and the horizontal plane. The electromagnetic device 11 is a commercially available high-power electromagnetic device 11, designed as a safety redundancy for the climbing platform. The rubber pad 12 at the front of the foot plug increases the friction with the outer surface of the steel tower.

[0034] Preferred, such as Figure 3 and Figure 7 As shown, multiple base beams 202 are surrounded and fixed with guardrails 203 at their outer ends, and multiple platform panels 204 are arranged overlapping each other. In this embodiment, the interval between two adjacent base beams 202 is 500mm to 700mm. Further, the base beams 202 are fixed to the square sleeves of the upper telescopic beam, and the square sleeves are fully welded to the base beams 202. The base beams 202 are also welded to the guardrails 203. The platform panels 204 are made of profiled steel sheets. To accommodate the expansion and contraction of the platform's load-bearing structure, the platform panels 204 consist of eight overlapping parts to adapt to changes in the platform's cross-section.

[0035] Preferred, such as Figure 2 and Figure 3 As shown, a control box 8 is fixed on the platform plate 204. The telescopic oil pump 9, the first electromagnetic foot plug 205, and the second electromagnetic foot plug 302 are all electrically connected to the control box 8. The control box 8 can provide power to the overall structure and perform centralized control, improving control efficiency and convenience.

[0036] The climbing platform of this invention is fixed mainly by utilizing the principle that the cross-section of the steel tower gradually decreases from bottom to top. The upper telescopic ring 201 and the lower telescopic ring 301 restrict the overall platform from sliding down by tightening the cross-section, while the contraction of the entire platform is achieved by the square sleeves at the intersections of the various rods in conjunction with the telescopic oil pump 9. When the platform rises, the lower telescopic ring 301 is first ensured to be tightly attached to and tightened with the tower column 1. The first electromagnetic foot plug 205 and the telescopic oil pump 9 are controlled to loosen the upper telescopic ring 201 from the tower column 1. Then, the telescopic oil pumps 9 located on the main inclined rod 4 and all the secondary inclined rods 5 are controlled to extend, so that the upper platform 2 is raised as a whole. At the same time, the telescopic oil pumps 9 of the first limit rod 7 and the second limit rod 6 keep the upper platform 2 horizontal. Retract the upper telescopic ring 201 and the first limiting rod 7, and adjust the first electromagnetic foot plug 205 and the third electromagnetic foot plug 401 to fit tightly against the tower column 1. Control the second electromagnetic foot plug 302 and the telescopic oil pump 9 to loosen the lower telescopic ring 301 from the tower column 1. Finally, control the telescopic oil pump 9 on the main inclined rod 4 and all the auxiliary inclined rods 5 to retract, so that the lower support frame 3 is lifted as a whole. Retract the lower telescopic ring 301 and the second limiting rod 6, and adjust the second electromagnetic foot plug 302 to fit tightly against the tower column 1. After all the rods are tightly against the tower column 1, the upper platform 2 can be guaranteed to be stable and reliable, thereby realizing one climbing operation of the climbing work platform.

[0037] This invention relates to a climbing work platform used for the construction of tower column segment 1 and the installation of external decorative panels. The platform is movable both vertically and horizontally. During tower column segment installation, after the first segment is installed, the work platform is hoisted from the top of the segment and placed over the outside of the tower column 1. The lower telescopic ring 301 and the telescopic oil pump 9 of the second limiting rod 6 connected to the lower telescopic ring 301 are adjusted to ensure the entire climbing work platform is in a balanced state. Then, the next tower column segment 1 is hoisted and fixed. After fixing, the upper telescopic ring 201 and the telescopic oil pump 9 of the first limiting rod 7 connected to the upper telescopic ring 201 are adjusted to ensure a suitable height and stable, reliable operation. After the workers complete their welding work on the platform, the platform is raised and fixed according to the above operating sequence, and welding work is resumed. This process is repeated until the top of the tower is reached.

[0038] The installation of the exterior decorative panels of the tower generally proceeds from the top to the bottom. The tower column 1 working platform is lowered in the reverse order until all decorative panels are installed. Finally, at the base of the tower, the hinge joints 13 of the platform members are disassembled, and the entire climbing working steel platform is removed.

[0039] This invention solves the technical problem of the lack of a suitable climbing platform for the construction of inclined, variable-section main towers of bridges by combining an adjustable-diameter lower support frame 3 with an upper platform 2. The invention uses a control box 8 to control an electrical switch to achieve the vertical climbing and circumferential retraction of the entire platform. During retraction, the platform surface remains level, ensuring safety and reliability without damaging the steel tower, thus enabling decorative construction operations on the steel tower and demonstrating high practicality.

[0040] All parts not described in this invention are the same as or can be implemented using existing technologies. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, shall still fall within the scope of the present invention.
