Description

Technical Field

[0001] This utility model relates to the field of prefabricated cable tower construction technology, specifically an adjustable cable tower segment installation operation platform. Background Technology

[0002] Prefabricated cable tower technology was adopted during the construction of the Gu Niu He Grand Bridge. Due to the significant weight and height of the corresponding cable tower segments (5.535m), the lifting equipment lacked the capacity to lift the entire segment. Therefore, a technique of dividing the segment into two pieces for installation was proposed. Currently, there are no facilities available for connecting the connecting rods between the two pieces during the cable tower segment installation process. To address this, a simple and practical adjustable cable tower segment installation operation platform was specifically designed. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable cable tower segment installation operation platform, which can be quickly hung on the segment, so that operators can enter the platform to install the connecting rods between the segments.

[0004] This utility model provides the following technical solution to achieve the above objectives:

[0005] An adjustable cable tower segment installation and operation platform includes a main frame composed of several horizontal, longitudinal and vertical poles, with two operating platforms formed on the main frame and connected by a ladder; from a top view, the main frame is U-shaped, and two layers of fastening components extend from the main frame to the U-shaped opening, with each fastening component having at least two fasteners.

[0006] In the aforementioned adjustable cable tower segment installation and operation platform, the main frame includes two continuous vertical rods, the upper and lower parts of which are respectively connected to cantilevered longitudinal beams, and the rear parts of the two cantilevered longitudinal beams of the upper and lower layers are respectively connected to at least two continuous horizontal rods; several distribution beams are connected between the continuous horizontal rods, and a steel mesh layer is laid on the distribution beams; the upper and lower steel mesh layers form two layers of operation platform.

[0007] In the aforementioned adjustable cable tower segment installation and operation platform, the steel mesh layer and the distribution beam are tied and fixed.

[0008] In the aforementioned adjustable cable tower segment installation and operation platform, the front of the two cantilevered longitudinal beams of the upper and lower layers are equipped with hooks. The front of the upper and lower cantilevered longitudinal beams and the corresponding hooks form an upper and lower hook assembly. The hooks include two hook vertical rods that are bolted downward to the front of the cantilevered longitudinal beams. The rear hook vertical rod is hinged to the rear end of the hook switch through a fixed shaft. After the hook switch rotates around the fixed shaft, the front end of the hook switch can be connected to the bottom of the front hook vertical rod through a movable safety pin.

[0009] In the aforementioned adjustable cable tower segment installation operation platform, a reinforcing plate is provided at the connection position of the hook switch, the fixed shaft, and the movable safety pin; the reinforcing plate and the hook switch are provided with holes for the fixed shaft and the movable safety pin to pass through, and the bottom of the front hook vertical rod is provided with holes for the movable safety pin to pass through.

[0010] In the aforementioned adjustable cable tower segment installation and operation platform, a horizontal brace is connected between the two continuous vertical rods located below the upper and lower operation platforms.

[0011] In the aforementioned adjustable cable tower segment installation and operation platform, at the connection point between the continuous vertical rod and the horizontal brace, the continuous vertical rod is also connected to the operation platform by diagonal braces.

[0012] In the aforementioned adjustable cable tower segment installation and operation platform, several guardrails are installed around the two-layer operation platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example: An adjustable cable tower segment installation operation platform.

[0026] This platform is used for cable tower segment installation. A cable tower segment consists of four columns and connecting rods that connect the columns. The cable tower segment is divided into two sections for installation. The sections are formed on a jig. The section structure includes two columns, which are connected by three horizontally arranged connecting rods (top, middle, and bottom) and two inclined connecting rods. (See section structure reference.) Figure 5 As shown. After installing the two panels via the flanges at the ends of the columns, hang the platform on the panels. Then, install the connecting rods between the panels (the rods shown by the dotted lines in the diagram). Refer to the platform's operating status for details. Figure 7 As shown.

[0027] The structural reference of this platform Figure 1-4 As shown, the system includes a main frame composed of several horizontal, vertical, and longitudinal rods. Two operating platforms are formed on the main frame, and the two operating platforms are connected by a ladder 12. From a top view, the main frame is U-shaped, and two layers of hook-and-loop components extend from the main frame into the U-shaped opening. Each hook-and-loop component has at least two hooks. The upper and lower hook-and-loop components can be hung on two horizontally arranged connecting rods on the plate. The U-shaped design and the two-layer operating platform setup allow operators to enter the platform and walk to the corresponding positions on the two operating platforms to perform operations on the connecting rods that need to be installed on both sides of the plate.

[0028] The main frame includes two continuous vertical rods 3, with cantilevered longitudinal beams 1 connected to the upper and lower parts of the vertical rods 3, respectively. At least two continuous horizontal rods 2 are connected to the rear parts of the two cantilevered longitudinal beams 1 on both the upper and lower layers. Several distribution beams 6 are connected between the continuous horizontal rods 2, and a steel mesh layer is laid on the distribution beams 6. The upper and lower steel mesh layers form a two-level operating platform for operators to walk on. Operators can walk on the steel mesh layer, with the main frame bearing the weight.

[0029] The steel mesh layer and the distribution beam 6 are tied and fixed to prevent the steel mesh layer from loosening.

[0030] The front of the two cantilever beams 1 of the upper and lower layers is equipped with hooks. The front of the upper and lower cantilever beams 1 and the corresponding hooks form a two-layer hook assembly. The hooks include two hook vertical rods 13 bolted downward to the front of the cantilever beams 1. The rear hook vertical rod 13 is hinged to the rear end of the hook switch 14 through a fixed shaft 15. After the hook switch 14 is rotated about the fixed shaft 15, the front end of the hook switch 14 and the bottom of the front hook vertical rod 13 can be connected through a movable safety pin 16. The working principle of the hook is as follows: In the initial state, the movable safety pin 16 is not inserted into the hook. At this time, the hook switch 14 hangs down naturally with the fixed shaft 15 as the rotation point. After the platform is hoisted to the corresponding position, the horizontal bar on the plate is inserted from the opening below the hook. The hook switch 14 is manually rotated to the front, and the movable safety pin 16 is inserted into the front end of the hook switch 14 and the front hook vertical rod 13, thereby locking the horizontal bar on the plate in the hook. After securing all four hooks, the platform can be fixed onto the film.

[0031] A reinforcing plate 17 is provided at the connection position between the hook switch 14, the fixed shaft 15, and the movable safety pin 16. The reinforcing plate 17 and the hook switch 14 have holes for the fixed shaft 15 and the movable safety pin 16 to pass through. The bottom of the front hook vertical rod 13 also has a hole for the movable safety pin 16 to pass through. The reinforcing plate 17 enhances the strength of the hook switch 14.

[0032] Located below the upper and lower operating platforms respectively, the two continuous vertical rods 3 are connected by a horizontal brace 5.

[0033] At the connection point between the continuous vertical rod 3 and the horizontal brace 5, the continuous vertical rod 3 is also connected to the operating platform via diagonal braces 4. The horizontal braces 5 and diagonal braces 4 enhance the strength of the platform's main frame.

[0034] Several guardrails are installed around the two-level operating platform. These guardrails protect worker safety and are of conventional design, consisting of welded vertical and horizontal bars surrounding the two levels of the platform. (See attached diagram.) Figure 1-3 It can be seen that the guardrail includes guardrail 1 (7), guardrail 2 (8), guardrail 3 (9), guardrail 4 (10), guardrail 5 (11), and the outer guardrail.

[0035] When implementing this platform, common profiles were used for construction, with Q235 material. The cantilever longitudinal beam 1, continuous vertical bar 3, and hanging vertical bar 13 were made of double-jointed 10# channel steel; the continuous horizontal bar 2, diagonal brace 4, and horizontal brace 5 were made of single 10# channel steel; other distribution beams 6, guardrails, and other members were made of square steel. Except for the bolt connection method shown in the figure, all other components were fixed by welding.

[0036] The construction scenarios and operating principles of this platform are as follows:

[0037] A 25t crane was used for the installation of the sheet metal sections.

[0038] Before installing the cable tower segments, the column bases are installed first. After verifying that the verticality of the installation is correct, the segments are hoisted onto the column base flanges. After alignment, they are fixed with high-strength bolts. After the two segments are installed on a cable tower column base, the connecting rods between the two segments are installed using this platform.

[0039] The steps for installing the connecting rods between two sections using this platform include: hoisting the platform to the installation position using a 16t crane; and securing the platform to the two adjacent horizontally arranged connecting rods of the sections using four hooks. (Refer to...) Figure 6 As shown, workers enter the platform via a safety ladder cage and connect the members between the two sections. The specific connection process involves using a tower crane to hoist the connecting members into position, followed by steel pin connections. After connecting all the members between the two sections using the same method (referring to the method of installing the connecting members on one side of the two sections via the platform, and then installing the connecting members on the other side of the two sections after removing the platform), the installation of one cable tower section is completed. After installation, the fasteners are removed, the platform is hoisted and dismantled, and the verticality of the installation is checked to ensure the quality of the cable tower section installation.

[0040] This platform, in conjunction with a crane, allows for the attachment and securing of cables to panels at varying heights. See the attached image for a completed cable tower installation using this platform. Figure 8 As shown.

[0041] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
