Description

Technical Field

[0001] This utility model relates to the field of bridging technology, and more specifically to a bridging flipping assembly. Background Technology

[0002] Crossing frames are widely used in power and telecommunications engineering construction. They are primarily used to protect and support objects being crossed during overhead line construction, ensuring safety and smooth progress. With the continuous development of engineering projects, the performance requirements for crossing frames are becoming increasingly stringent.

[0003] Traditional scaffolding systems are typically constructed using bamboo, wooden, or steel poles, densely and intersecting in a longitudinal, transverse, and diagonal pattern. This method has several drawbacks. First, the extensive manual handling and assembly work is not only time-consuming and labor-intensive but also severely impacts construction progress. Second, as the height increases, workers inevitably need to perform assembly work at heights, posing safety hazards.

[0004] To address this, our company offers a gantry that can be quickly assembled on flat ground and then flipped up. However, after flipping, workers need to manually tighten the gantry using bolts. This bolt-connection method is not only time-consuming and labor-intensive when assembling and dismantling the gantry, but also poses a safety risk when approaching the gantry before it is tightened.

[0005] Therefore, how to safely and conveniently erect and dismantle the crossing frame is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] To enable safe and convenient erection and dismantling of crossing frames, this application provides a flipping assembly for crossing frames.

[0007] The flipping assembly of the gantry provided in this application adopts the following technical solution:

[0008] A flipping assembly for a straddle includes a fixed base, a swing base, and a rotating mechanism. The fixed base and the swing base are rotatably connected by the rotating mechanism. A locking mechanism is provided on the side of the fixed base and the swing base away from the rotating mechanism. An unlocking mechanism is provided on the fixed base corresponding to the locking mechanism.

[0009] Furthermore, the fixing base includes several first supporting steel pipes arranged at the corners of the tower column assembly frame. Several first angle steels are fixedly connected between the first supporting steel pipes at the sides of the tower column assembly frame. The first angle steels are fixedly connected to the outer sides of the first supporting steel pipes near their two ends.

[0010] Furthermore, a first triangular plate is fixedly connected between each of the two adjacent first angle steels, and a first mounting hole is provided on the first triangular plate.

[0011] Furthermore, the swing seat includes several second support steel pipes arranged at the corners of the tower column assembly frame. Several second angle steels are fixedly connected between the second support steel pipes at the sides of the tower column assembly frame. The second angle steels are fixedly connected to the outer sides of the second support steel pipes near their two ends.

[0012] Furthermore, a second triangular plate is fixedly connected between each of the two adjacent second angle steels, and a second mounting hole is provided on the second triangular plate.

[0013] Furthermore, the rotating mechanism includes a fixed rod, a rotating rod, and a hinge shaft. The fixed rod is fixedly connected to the fixed base, the rotating rod is fixedly connected to the swing base, and the fixed rod and the rotating rod are hinged together by the hinge shaft.

[0014] Furthermore, the locking mechanism includes a mounting base, on which two mounting bases are fixedly mounted. Two locking pins are symmetrically slidably connected inside each of the two mounting bases. A spring is abutting between the inner end of each locking pin and the interior of each mounting base. A locking hole is provided on the fixed base corresponding to the mounting base, and an inclined surface is provided on the locking pin corresponding to the locking hole.

[0015] Furthermore, the unlocking mechanism includes a first push frame, a second push frame, a third push frame, and a fourth push frame. Each of the first push frame, the second push frame, the third push frame, and the fourth push frame has a push surface corresponding to each locking pin. The first push frame and the second push frame are symmetrically arranged and slidably connected to the fixed base. The third push frame and the fourth push frame are symmetrically arranged and slidably connected to the fixed base. The first push frame and the third push frame are fixedly connected. The second push frame and the fourth push frame are fixedly connected. A drive mechanism is provided on the fixed base corresponding to the first push frame and the second push frame.

[0016] Furthermore, the drive mechanism includes a rotating shaft rotatably connected to the fixed base. A cam is fixedly connected to one end of the rotating shaft located inside the fixed base. The cam is located between the first push frame and the second push frame to push the first push frame and the second push frame to move away from each other. A drive member is fixedly connected to one end of the rotating shaft located outside the fixed base.

[0017] Furthermore, a tension spring is fixedly connected between the first push frame and the second push frame, and the tension spring is used to pull the first push frame and the second push frame to move towards each other.

[0018] Beneficial effects achieved:

[0019] This application enables the fixed seat and the swing seat to form a rotatable connection through the rotation mechanism. When the fixed seat and the swing seat are closed together, the locking mechanism will automatically lock the fixed seat and the swing seat together. When it is necessary to separate the fixed seat and the swing seat, the locking between the fixed seat and the swing seat can be released through the unlocking mechanism. This allows for the safe and convenient erection and dismantling of the crossing frame. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0029] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model 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 a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] This application discloses a flipping assembly for a gantry.

[0032] Please refer to Figure 1First, it should be noted that the gantry frame with the flipping component includes a base 901, which is fixedly installed on the ground. A fixed steel frame 902 is fixedly connected to the base 901. The flipping component 904 is fixedly installed on the fixed steel frame 902, and several vertically arranged assembly aluminum frames 903 are fixedly installed on the flipping component 904. The base 901, fixed steel frame 902, assembly aluminum frames 903, and flipping component 904 constitute the tower column assembly frame 900. When installing the tower column assembly frame 900, the base 901 is first fixedly installed on the ground, and the fixed steel frame 902 is fixedly installed on the base 901. Then, the flipping component 904 is installed on the fixed steel frame 902, which can be used to flip the frame. Then, the assembly aluminum frames 903 are installed sequentially on the flipping component 904. When the assembly aluminum frames 903 reach the designed height, the flipping component 904 is used to flip the assembly aluminum frames 903 to a vertical position, thus quickly assembling the tower column assembly frame 900 on the ground.

[0033] Please refer to the above as well. Figures 1 to 7 In one embodiment of this application, a flipping assembly for a gantry frame includes a fixing base 100. The fixing base 100 is welded together from four first support steel pipes 101 and eight first angle steels 102. The four first support steel pipes 101 are vertically arranged corresponding to the corners of the tower column assembly frame 900. The eight first angle steels 102 are symmetrically welded in pairs to the outer sides of the first support steel pipes 101 near their two ends. Using the first support steel pipes 101 and the first angle steels 102 for fixed connection by welding ensures the structural strength and stability of the fixing base 100 during use.

[0034] It is understood that in other embodiments of this application, the fixing base 100 may also be made of other materials or structures that can ensure the structural strength and stability of the fixing base 100. For example, it may be made of welded steel plates or cast iron in one piece.

[0035] Please refer to the above as well. Figures 1 to 7 In one embodiment of this application, two first support steel pipes 101 located on one side of the fixed base 100 are each fitted with a fixed rod 301. After the fixed rod 301 is fitted, it is welded to the connection between the fixed rod 301 and the first support steel pipe 101. A hinge shaft 303 is rotatably connected to the fixed rod 301, and a rotating rod 302 is rotatably connected to the hinge shaft 303. The fixed rod 301, the rotating rod 302, and the hinge shaft 303 form a rotating mechanism 300. A swing seat 200 is fixedly connected to the end of the rotating rod 302 away from the fixed rod 301 and the hinge shaft 303. The fixed base 100 and the swing seat 200 can be rotatably connected through the rotating mechanism 300. In this way, by fixing the assembly aluminum frame 903 on the swing seat 200, the assembly aluminum frame 903 can be flipped relative to the fixed steel frame 902.

[0036] Please refer to the above as well. Figures 1 to 7 In one embodiment of this application, the swing seat 200 is welded from four second support steel pipes 201 and eight second angle steels 202. The four second support steel pipes 201 are vertically arranged corresponding to the corners of the tower column assembly frame 900, and the eight second angle steels 202 are symmetrically welded to the outer sides of the second support steel pipes 201 near their two ends. Using the second support steel pipes 201 and the second angle steels 202 for fixed connection by welding ensures the structural strength and stability of the swing seat 200 during use.

[0037] It is understood that in other embodiments of this application, the swing seat 200 may also be made of other materials or structures that can ensure the structural strength and stability of the swing seat 200. For example, it may be made of welded steel plates or cast iron in one piece.

[0038] Please refer to the above as well. Figures 1 to 7 In one specific embodiment of this application, the two second supporting steel pipes 201 are cut at the connection lengths of the fixed rod 301 and the rotating rod 302, and the rotating rod 302 is inserted into them accordingly. The connection between the rotating rod 302 and the second supporting steel pipes 201 is also fixed by welding. This ensures the connection strength between the rotating rod 302 and the second supporting steel pipes 201 and the stability of the overall structure.

[0039] It is understood that in other embodiments of this application, the fixed rod 301 and the first supporting steel pipe 101, as well as the rotating rod 302 and the second supporting steel pipe 201, can be connected by insertion and welding, or by interference fit, or by direct welding, or by insertion and screw locking.

[0040] Please refer to the above as well. Figures 1 to 7 In one specific embodiment of this application, two adjacent first angle steels 102 are fixedly connected by welding to a first triangular plate 103, and the first triangular plate 103 is provided with a first mounting hole 104. During use, the fixing seat 100 can be conveniently fixed to the fixing steel frame 902 by bolts through the first triangular plate 103 and the first mounting hole 104.

[0041] Please refer to the above as well. Figures 1 to 7In one specific embodiment of this application, two adjacent second angle steels 202 are fixedly connected by welding to a second triangular plate 203, and the second triangular plate 203 is provided with a second mounting hole 204. During use, the assembly aluminum frame 903 can be conveniently fixed to the swing seat 200 by bolts through the second triangular plate 203 and the second mounting hole 204.

[0042] Please refer to the above as well. Figures 1 to 7 In one specific embodiment of this application, a locking mechanism 400 is provided on the side of the fixed base 100 and the swing base 200 away from the rotating mechanism 300. The locking mechanism 400 includes a mounting base 401. Two mounting bases 401 are fixedly mounted on the swing base 200. Two locking pins 402 are symmetrically slidably connected inside each of the two mounting bases 401. A spring 403 is abutting between the inner end of the locking pin 402 and the inside of the mounting base 401. A locking hole 404 is provided on the fixed base 100 corresponding to the mounting base 401, and an inclined surface 405 is provided on the locking pin 402 corresponding to the locking hole 404.

[0043] During use, when the fixed base 100 and the swing base 200 are closed together, the mounting base 401 will drive the locking pin 402 to move into the locking hole 404. Before the locking pin 402 passes through the locking hole 404, the inclined surface 405 on the locking pin 402 will slide at the edge of the locking hole 404, thereby pushing the spring 403 to retract into the mounting base 401. After the locking pin 402 passes through the locking hole 404, the locking pin 402 will pop out from the mounting base 401 under the action of the spring 403, thereby locking the fixed base 100 and the swing base 200 together. In this way, after the assembly aluminum frame 903 is rotated to a vertical position, it is no longer necessary for workers to manually lock the flipped cross-frame by directly connecting bolts. The automatic locking method of the locking mechanism 400 not only saves time and effort, but also reduces the safety risks when approaching the cross-frame before it is locked. Thus, it achieves a safe and convenient locking of the cross-frame.

[0044] Please refer to the above as well. Figures 1 to 7In one specific embodiment of this application, an unlocking mechanism 500 is provided on the fixed base 100 corresponding to the locking mechanism 400. The unlocking mechanism 500 includes a first pusher 501, a second pusher 502, a third pusher 503, and a fourth pusher 504. Each of the first pusher 501, the second pusher 502, the third pusher 503, and the fourth pusher 504 is provided with a push surface 505 corresponding to each locking pin 402. The first pusher 501 and the second pusher 502 are symmetrically arranged and slidably connected to the fixed base 100. The third pusher 503 and the fourth pusher 504 are symmetrically arranged and slidably connected to the fixed base 100. The first pusher 501 and the third pusher 503 are fixedly connected, and the second pusher 502 and the fourth pusher 504 are fixedly connected. A driving mechanism 600 is provided on the fixed base 100 corresponding to the first pusher 501 and the second pusher 502.

[0045] During use, when the crossing frame needs to be dismantled, the first push frame 501 and the second push frame 502 are driven by the drive mechanism 600 to move away from each other. This synchronously drives the third push frame 503 and the fourth push frame 504 to move closer to each other. During the movement, the first push frame 501, the second push frame 502, the third push frame 503, and the fourth push frame 504 will push the corresponding locking pins 402 towards the interior of the mounting base 401 through the push surface 505. The locking hole 404 will then release the restriction on the locking pins 402, and the fixed base 100 and the swing base 200 can be separated from each other. The assembly aluminum frame 903 on the tower column assembly frame 900 can be laid down using an external hoisting device, so that the assembly aluminum frame 903 can be dismantled on the ground.

[0046] Please refer to the above as well. Figures 1 to 7 In one specific embodiment of this application, both the first push frame 501 and the second push frame 502 are provided with a first sliding groove 506, and a first sliding frame 507 is slidably connected inside the first sliding groove 506. The first sliding frame 507 is fixedly installed on the fixed base 100. Both the third push frame 503 and the fourth push frame 504 are provided with a second sliding groove 508, and a second sliding frame 509 is slidably connected inside the second sliding groove 508. The second sliding frame 509 is also fixedly installed on the fixed base 100. During use, the first sliding frame 507 can provide stable and reliable support for the first push frame 501 and the second push frame 502, and the second sliding frame 509 can provide stable and reliable support for the third push frame 503 and the fourth push frame 504.

[0047] Please refer to the above as well. Figures 1 to 7In one specific embodiment of this application, the drive mechanism 600 includes a rotating shaft 601, which is rotatably connected to the fixed base 100. A cam 602 is fixedly connected to one end of the rotating shaft 601 located inside the fixed base 100. The cam 602 is located between the first push frame 501 and the second push frame 502 to push the first push frame 501 and the second push frame 502 to move away from each other. A drive member 603 is fixedly connected to one end of the rotating shaft 601 located outside the fixed base 100.

[0048] During use, the drive component 603 drives the rotating shaft 601 to rotate, which in turn drives the cam 602 to rotate. After the cam 602 rotates, it pushes the first push frame 501 and the second push frame 502 to move away from each other. At the same time, the third push frame 503 and the fourth push frame 504 move closer to each other. During the movement, the first push frame 501, the second push frame 502, the third push frame 503, and the fourth push frame 504 will push the locking pin 402 to retract towards the interior of the mounting base 401 through the push surface 505. The locking hole 404 will then release the restriction on the locking pin 402, thereby completing the unlocking.

[0049] Please refer to the above as well. Figures 1 to 7 In one specific embodiment of this application, the driving member 603 can be configured as a regular hexagon suitable for wrench driving, so that the rotating shaft 601 can be rotated by the wrench.

[0050] It is understood that in other specific embodiments of this application, the drive component 603 may also be configured as a drive mechanism such as a motor that can drive the rotating shaft 601.

[0051] Please refer to the above as well. Figures 1 to 7 In one specific embodiment of this application, a tension spring 700 is fixedly connected between the first push frame 501 and the second push frame 502. The tension spring 700 is used to pull the first push frame 501 and the second push frame 502 to move towards each other. By setting the tension spring 700, the first push frame 501 and the second push frame 502 can move towards each other, while the third push frame 503 and the fourth push frame 504 will move synchronously away from each other. This avoids the first push frame 501 and the second push frame 502, as well as the third push frame 503 and the fourth push frame 504, obstructing the locking pin 402 before it passes through the locking hole 404 when the fixed seat 100 and the swing seat 200 are closed. This ensures that the locking pin 402 can smoothly pass through the locking hole 404, thereby guaranteeing the reliability of the unlocking mechanism 500 during use.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
