Description

Technical Field

[0001] This utility model relates to the field of transformer assembly equipment technology, specifically to a transformer body assembly platform. Background Technology

[0002] In existing technologies, during the assembly of large transformers, a transformer assembly platform is typically used to provide a suitable operating height for workers to perform assembly operations. In actual assembly, the transformer assembly platform must first be moved to the assembly station manually or using traction equipment, then the large transformer is moved to the assembly station using hoisting equipment, and finally the assembly workshop is moved to the assembly station.

[0003] To meet operational requirements, it is generally necessary to install a transformer assembly platform on each side of the transformer. However, this arrangement results in the assembly platforms occupying a significant amount of space within the assembly workshop, leading to wasted space. Furthermore, during the process of moving the assembly workshop to the assembly station, larger transformers are prone to interference with the assembly platforms. Additionally, before each assembly, both the assembly platforms and the assembly workshop must be moved to the assembly station, and after assembly, they must be moved again to remove them from the assembly station. This cumbersome and time-consuming handling process negatively impacts the overall assembly efficiency and operational smoothness of the transformer.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a body assembly platform to solve the technical problem that the body assembly platform occupies a large placement space in the assembly workshop, resulting in a waste of internal space in the assembly workshop.

[0013] Furthermore, the assembly platform includes: a first support base for supporting a first assembly platform; a second support base for supporting a second assembly platform; and a connecting ladder, one end of which is rotatably connected to the first support base and the other end of which is rotatably connected to the second support base.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] According to an embodiment of this utility model, a body assembly platform is provided. Please refer to [link / reference]. Figures 1 to 3 The assembly includes: an assembly platform 1, which is installed on the inner wall 101 of the assembly workshop 10; a telescopic device 2, which is connected to the inner wall 101 and the assembly platform 1 respectively, and drives the assembly platform 1 to move along a direction perpendicular to the inner wall 101 so that the assembly platform 1 moves closer to or further away from the product to be assembled; and a lifting device 3, which is connected to the inner wall 101 and the assembly platform 1 respectively, and drives the assembly platform 1 to move along the height direction of the assembly workshop 10.

[0027] Specifically, the telescopic device 2 is connected to the inner wall 101 and the assembly platform 1 respectively. The telescopic device 2 drives the assembly platform 1 to move along a direction perpendicular to the inner wall 101, so that the assembly platform 1 can move closer to or away from the product to be assembled. This allows the assembly platform to have a foldable function. When the assembly platform 1 is not in use, it can be folded to reduce the space occupied by the assembly table in the assembly workshop. This facilitates the entry of the transformer into the assembly workshop 10 during the movement of the assembly workshop. Moreover, by controlling the action of the telescopic device 2, the moving distance of the assembly platform 1 can be controlled, so that the assembly platform can move closer to or away from the product to be assembled, so that the operator can complete the assembly task in the best position, making the assembly table more flexible.

[0028] Specifically, the lifting device 3 is connected to both the inner wall 101 and the assembly platform 1, and is used to drive the assembly platform 1 to move along the height direction of the assembly workshop 10. The design of the lifting device 3 takes into account the assembly needs at different heights, allowing operators to adjust the working height according to specific circumstances, thereby improving work efficiency and safety.

[0029] By fixing the assembly platform 1 to the inner wall 101, the inner wall and the fixed structure are used as the support frame of the assembly platform. There is no need to set up an additional support frame to support the assembly platform, which reduces the space occupied by the support frame in the assembly workshop. This not only ensures the stability of the platform during the assembly process, but also makes effective use of space and reduces the space occupied in the assembly workshop.

[0030] In this embodiment, the transformer body assembly platform is integrated into the inner wall of the assembly workshop, and the assembly platform 1 can be folded inside the assembly workshop without the need for additional support frames. This reduces the space occupied by the support frames in the assembly workshop and solves the technical problem in related technologies where the transformer body assembly platform occupies a large placement space in the assembly workshop, resulting in wasted space. In addition, during the transformer assembly process, there is no need to move the assembly workshop and the transformer body assembly frame independently. Only the assembly workshop needs to be moved to complete the transportation and adjustment of the assembly workshop and the transformer body assembly platform, which improves the overall assembly efficiency and smoothness of the transformer.

[0031] In the assembly platform of this embodiment, see... Figure 1 The lifting device 3 includes: a first slider 311 and a first slide rail 312 slidably connected to the first slider 311. The first slider 311 is fixedly connected to the assembly platform 1, and the first slide rail 312 is fixedly installed on the inner wall 101 of the assembly workshop 10. The extension direction of the first slide rail 312 is consistent with the height direction of the assembly workshop 10. A first drive assembly 313 is drivenly connected to the first slider 311 to drive the slider to move along the extension direction of the first slide rail 312. In this way, the first drive assembly 313 can effectively drive the first slider 311 to move along the extension direction of the first slide rail 312, realizing precise positioning and smooth lifting of the assembly platform 1, and enabling automatic control of the lifting of the assembly platform 1.

[0032] In some embodiments, during the process of moving the assembly workshop to the assembly station, the assembly platform 1 can be raised to its highest position, thereby facilitating the entry of the transformer into the assembly workshop 10 during the movement of the assembly workshop.

[0033] In some embodiments, both the first slider 311 and the first slide rail 312 include two, and the two first slide rails 312 are spaced apart along the extension direction of the assembly platform 1.

[0034] In some embodiments, the first drive assembly 313 includes a cross arm and a fixed base, as well as a hydraulic rod drivenly connected to the cross arm. The fixed base is located below the support base 4, and the cross arm is located between the support base 4 and the fixed base. The cross arm includes a first connecting rod and a second connecting rod that are cross-connected to each other. One end of the first connecting rod is rotatably connected to the support base 4, and the other end is slidably connected to the fixed base. One end of the second connecting rod is rotatably connected to the fixed base, and the other end is slidably connected to the support base 4. The main body of the hydraulic rod is rotatably connected to the inner wall 101, and the free end of the telescopic rod of the hydraulic rod is hinged to the intersection of the first connecting rod and the second connecting rod.

[0035] In the assembly platform of this embodiment, by setting up the lifting device 3, not only can the assembly platform 1 be controlled to move up and down, but the cross arm and fixed base also improve the structural stability of the assembly platform and play a further supporting role, so as to stably support the assembly platform 1 on the inner wall.

[0036] In the assembly platform of this embodiment, see... Figure 1 The assembly platform includes a support base 4, on which an assembly platform 1 is movably mounted. The support base 4 is fixedly connected to the first slider 311. By setting the support base 4, which is located below the assembly platform 1, it supports the assembly platform 1. By setting the telescopic device 2, the assembly platform 1 can move relative to the support base 4, thereby realizing the folding function.

[0037] In the assembly platform of this embodiment, see... Figure 1-2 The support base 4 includes: a first support plate 411 on which an assembly platform 1 is mounted; and a second support plate 412 on which a first slider 311 is mounted. The second support plate 412 is fixedly connected to the first support plate 411 and is perpendicular to the first support plate 411. Specifically, the first slider 311 is located on the side of the second support plate 412 near the inner wall 101, so that the entire assembly platform is installed close to the wall. The first support plate 411 serves as the main load-bearing component, and the vertical arrangement between the two support plates forms a robust three-dimensional frame structure, enhancing the overall stability and load-bearing capacity.

[0038] In the assembly platform of this embodiment, see... Figure 1The telescopic device 2 includes: a second slider 211 and a second slide rail 212 slidably connected to the second slider 211. The second slider 211 is fixedly connected to the assembly platform 1, and the second slide rail 212 is fixedly mounted on the support base 4. The extension direction of the second slide rail 212 is perpendicular to the inner wall 101. A second drive assembly 213 is drivenly connected to the second slider 211 to drive the slider to move along the extension direction of the second slide rail 212. In this way, the second drive assembly 213 can effectively drive the second slider 211 to move along the extension direction of the second slide rail 212, realizing the precise positioning and movement of the assembly platform 1. The assembly platform 1 can move relative to the support base 4, thereby realizing the folding function.

[0039] In some embodiments, both the second slider 211 and the second slide rail 212 include two slide rails, and the two slide rails 212 are spaced apart along the extension direction of the assembly platform 1.

[0040] In the assembly platform of this embodiment, see... Figure 1 The second drive assembly 213 includes: a rack 2131, which is fixedly mounted on the assembly platform 1 and is arranged in a direction perpendicular to the inner wall 101; a gear, which is rotatably arranged and meshes with the rack 2131; and a drive motor 2132, which is mounted on the support base 4 and has a gear mounted on its output shaft. By setting up the rack 2131, the gear, and the drive motor 2132, high-precision and smooth telescopic motion control is achieved, which can automatically control the movement of the assembly platform 1 relative to the support base 4, thereby realizing the folding function.

[0041] In the assembly platform of this embodiment, see... Figure 1The assembly platform includes: a first assembly platform 11 and a second assembly platform 12, which are spaced apart along the extension direction of the inner wall 101; a first telescopic device 21 and a first lifting device 31, both of which are connected to the first assembly platform 11. The first telescopic device 21 is used to enable the first assembly platform 11 to move independently along a direction perpendicular to the inner wall 101, and the first lifting device 31 is used to enable the first assembly platform 11 to move independently along the height direction of the assembly workshop 10; a second telescopic device 22 and a second lifting device 32, both of which are connected to the second assembly platform 12. The second telescopic device 22 is used to enable the second assembly platform 12 to move independently along a direction perpendicular to the inner wall 101, and the second lifting device 32 is used to enable the second assembly platform 12 to move independently along the height direction of the assembly workshop 10. By setting up a first assembly platform 11 and a second assembly platform 12 spaced apart along the extension direction of the inner wall 101, the overall span of the transformer assembly platform is increased, making it suitable for assembling transformers of different lengths. Furthermore, since both the first assembly platform 11 and the second assembly platform 12 are equipped with independent telescopic and lifting devices, their motion control has a high degree of independence and flexibility. This allows the two assembly platforms to perform assembly operations at different positions or heights simultaneously without interference, thereby significantly improving assembly efficiency.

[0042] In the assembly platform of this embodiment, see... Figure 1 The assembly platform includes: a first support base 41 for supporting a first assembly platform 11; a second support base 42 for supporting a second assembly platform 12; and a connecting ladder 5, one end of which is rotatably connected to the first support base 41 and the other end of which is rotatably connected to the second support base 42. The connecting ladder 5 is retractable as the first support base 41 or the second support base 42 moves. The connecting ladder 5 connects the first support base 41 and the second support base 42, facilitating passage for operators. Since the connecting ladder 5 is rotatably connected to both the first and second support bases and retractable as they move, it adapts to changing angles and lengths when the two assembly platforms are at different heights, thus facilitating passage for operators.

[0043] Specifically, the connecting ladder 5 adopts a common telescopic ladder structure, which is a ladder composed of different ladder sections that are nested together, and the different ladder sections can be slidably connected.

[0044] In some embodiments, a guardrail is provided on the side of the connecting ladder 5 away from the inner wall to prevent accidents such as falls from heights.

[0045] In the assembly platform of this embodiment, see... Figure 1 and Figure 3 The assembly platform includes: a first ladder 6, with its first end rotatably mounted on the inner wall 101 and its second end rotatably mounted on a first support base 41, the first ladder 6 being extendable and retractable as the first support base 41 moves; and a second ladder 7, with its first end rotatably mounted on the inner wall 101 and its second end rotatably mounted on a second support base 42, the second ladder 7 being extendable and retractable as the second support base 42 moves. The first ladder 6 and the second ladder 7 facilitate operators climbing onto the first support base 41 and the second support base 42. When the first support base 41 or the second support base 42 moves, the corresponding ladder will also adjust accordingly. Therefore, the first ladder 6 and the second ladder 7 can automatically adjust their length and angle according to the position of the first support base 41 and the second support base 42, ensuring that operators can climb onto the first support base 41 and the second support base regardless of the assembly platform's position.

[0046] In some embodiments, the assembly platform is located in the same position as the assembly platform in the prior art, on the inner wall of the assembly workshop along the length direction, that is, on the inner wall without doors. Depending on actual needs, the assembly platform can be installed on the inner wall on one side of the assembly workshop or on both inner walls.
