Description

Technical Field

[0001] This utility model relates to the field of crane auxiliary equipment technology, and in particular to a detachable ladder for crane installation. Background Technology

[0002] Ladders are essential auxiliary equipment during crane installation, allowing workers to reach different heights of the crane for installation operations.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Traditional crane installation ladders are usually of a single, integral structure, making it difficult to disassemble the ladder body. Since different cranes have different installation height requirements, traditional ladders cannot be adjusted to meet actual needs when different heights are required, making installation difficult to suit the crane's requirements and thus affecting the normal operation of the work. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the ladder body is difficult to disassemble because the different height requirements of the crane installation makes it difficult to install the ladder according to the requirements of the crane, thus making the operation difficult. To this end, we propose a detachable ladder for crane installation.

[0005] To achieve the above objectives, this application adopts the following technical solution: a detachable ladder for crane installation, comprising a ladder body, a connecting ladder mounted on the surface of the ladder body, a disassembly device provided on the surface of the ladder body, the disassembly device comprising two connecting blocks, the two connecting blocks being fixedly connected to the ladder body, each of the two connecting blocks having a slot on its surface, the surface of the slot of each of the two connecting blocks being slidably connected to the connecting ladder, each of the two connecting blocks having a support rod fixedly connected to its surface, each of the two support rods having a long plate slidably connected to its arc surface, each of the long plates having a fixing rod slidably inserted therein, one end of each fixing rod being fixedly connected to a circular plate, and the surface of the connecting ladder having a fixing hole.

[0006] Preferably, the arc surface of the fixing rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the circular plate and the long plate, respectively.

[0007] Preferably, the arc surface of the support rod is rotatably connected to a rotating ring, the surface of the rotating ring is fixedly connected to the long plate, and the surface of the connecting block is provided with a recycling groove.

[0008] Preferably, a positioning plate is fixedly connected to the surface of the connecting block, and the size of the fixing rod is adapted to the size of the fixing hole.

[0009] Preferably, the surface of the ladder body is provided with a sliding groove, and the surface of the sliding groove of the ladder body is provided with an auxiliary device. The auxiliary device includes a safety buckle connecting plate, which is slidably connected to the surface of the sliding groove of the ladder body. An auxiliary plate is fixedly connected to the surface of the safety buckle connecting plate, and a support plate is fixedly connected to the surface of the ladder body. A limiting rod is slidably inserted into the support plate, and a plurality of limiting holes are provided on the surface of the safety buckle connecting plate.

[0010] Preferably, a baffle is fixedly connected to the arc surface of the limiting rod, and the size of the limiting rod is adapted to the size of the limiting hole.

[0011] Preferably, two second springs are fixedly connected to the surface of the ladder body, and the two second springs are fixedly connected to the auxiliary plate.

[0012] The technical effects and advantages of this utility model are as follows: In this utility model, by setting up a disassembly device, the connecting ladder can be disassembled and installed, avoiding the situation where the ladder body is difficult to disassemble due to different crane installation height requirements, which makes it difficult to install the ladder according to the crane requirements, thus making the operation difficult, and improving the practicality of the device. In this invention, by setting up an auxiliary device, the safety of workers is improved. This avoids the situation where workers' safety ropes are difficult to attach to professional attachment points because there are no safety rope attachment points on the surface of the ladder itself, thus improving the practicality of the device.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figure 1 As shown, this utility model provides a technical solution: a detachable ladder for crane installation, including a ladder body 1, a connecting ladder 2 installed on the surface of the ladder body 1, and a disassembly device 3 on the surface of the ladder body 1. This avoids the situation where the ladder body 1 is difficult to disassemble due to different crane installation height requirements, making it difficult to install the ladder according to the crane requirements, thus making the operation difficult. This improves the practicality of the device. The surface of the ladder body 1 has a sliding groove, and the surface of the sliding groove of the ladder body 1 is equipped with an auxiliary device 4, which improves the safety of the workers and avoids the situation where the surface of the ladder body 1 lacks safety rope attachment points, making it difficult for workers to attach their safety ropes at professional attachment points. This further improves the practicality of the device.

[0017] The following section will describe the specific setup and function of its disassembly device 3 and auxiliary device 4.

[0018] Reference Figure 2 and Figure 3As shown in this embodiment: the disassembly device 3 includes two connecting blocks 301, which are fixedly connected to the ladder body 1. Each connecting block 301 has a slot on its surface, and the slot surfaces are slidably connected to the connecting ladder 2. Each connecting block 301 has a support rod 302 fixedly connected to its surface. Each support rod 302 has a long plate 304 slidably connected to its arc surface. Each long plate 304 has a fixing rod 305 slidably inserted into its long plate 304. One end of each fixing rod 305 is fixedly connected to a circular plate 307. The connecting ladder 2 has a fixing hole 308, and the arc surface of the fixing rod 305 is fitted with a first spring. Spring 306, the two ends of the first spring 306 are fixedly connected to the circular plate 307 and the long plate 304 respectively. When the circular plate 307 is released, the rebound force of the first spring 306 drives the circular plate 307, which in turn drives the fixed rod 305 to slide within the long plate 304 until the fixed rod 305 is inserted into the fixed hole 308. This achieves a stable connection of the fixed rod 305, preventing wobbling caused by external factors and thus improving the stability of the device. The arc surface of the support rod 302 is rotatably connected to a rotating ring 303, the surface of which is fixedly connected to the long plate 304. The surface of the connecting block 301 is provided with a recycling groove 309. The fixing rod 305 is pulled out from the fixing hole 308, and then the rotating ring 303 is rotated. The rotating ring 303 drives the long plate 304 to rotate on the arc surface of the support rod 302. The long plate 304 drives the fixing rod 305, and the fixing rod 305 drives the circular plate 307 until the fixing rod 305 is perpendicular to the recycling groove 309. Then, the circular plate 307 is pushed to drive the fixing rod 305 to slide within the long plate 304 until the fixing rod 305 is inserted into the recycling groove 309. This achieves the effect of rotating and recycling the fixing rod 305, avoiding the shaking caused during disassembly. 305 slides back and forth within the long plate 304, which affects disassembly. A positioning plate 310 is fixedly connected to the surface of the connecting block 301. The size of the fixing rod 305 matches the size of the fixing hole 308. Rotating the rotating ring 303 causes the long plate 304 to rotate on the arc surface of the support rod 302. The long plate 304 drives the fixing rod 305, and the fixing rod 305 drives the circular plate 307 until the fixing rod 305 touches the positioning plate 310, achieving the effect of quickly positioning the fixing rod 305, so that the workers can complete the disassembly or installation more quickly, thereby speeding up the work progress.

[0019] Reference Figure 4 and Figure 5As shown, specifically, the auxiliary device 4 includes a safety buckle connecting plate 41, which is slidably connected to the surface of the slide groove of the ladder body 1. An auxiliary plate 42 is fixedly connected to the surface of the safety buckle connecting plate 41, and a support plate 44 is fixedly connected to the surface of the ladder body 1. A limiting rod 45 is slidably inserted into the support plate 44. Several limiting holes 47 are opened on the surface of the safety buckle connecting plate 41. A baffle 46 is fixedly connected to the arc surface of the limiting rod 45. The size of the limiting rod 45 matches the size of the limiting holes 47. Pulling the limiting rod 45 to slide within the support plate 44 causes the limiting rod 45 to move the baffle 46 until the baffle 46 touches the support plate 44, thus blocking the limiting rod 45. This design avoids the situation where the limit rod 45 slips out of the support plate 44 due to shaking during adjustment, thus preventing damage to the limit rod 45 and making it unusable. Two second springs 43 are fixedly connected to the surface of the ladder body 1. The two second springs 43 are fixedly connected to the auxiliary plate 42. When the limit on the safety buckle connecting plate 41 is released, the rebound force of the second springs 43 drives the auxiliary plate 42, which in turn drives the safety buckle connecting plate 41 to slide in the slide groove of the ladder body 1 until it is reset. This achieves the effect of automatically resetting the safety buckle connecting plate 41, thereby reducing the number of operation steps for workers, increasing their work efficiency, and improving the convenience of the device.

[0020] Working principle: When the worker needs to disassemble the connecting ladder 2, the fixing rod 305 is pulled out from the fixing hole 308, and then the rotating ring 303 is rotated. The rotating ring 303 drives the long plate 304 to rotate on the arc surface of the support rod 302. The long plate 304 drives the fixing rod 305, and the fixing rod 305 drives the circular plate 307 until the fixing rod 305 touches the positioning plate 310. Then, the circular plate 307 is pushed to drive the fixing rod 305 to slide in the long plate 304 until the fixing rod 305 is inserted into the recycling groove 309. Then, the connecting ladder 2 is pulled out from the surface of the slot of the connecting block 301. When installing, the connecting ladder 2 is inserted into the surface of the slot of the connecting block 301, and then the fixing rod 305 is pulled out from the recycling groove 309. Rotating the rotating ring 303 causes the long plate 304 to rotate on the arc surface of the support rod 302. The long plate 304 drives the fixing rod 305, which in turn drives the circular plate 307 until the fixing rod 305 is perpendicular to the fixing hole 308. The circular plate 307 is then released, and the rebound force of the first spring 306 drives the circular plate 307. The circular plate 307 then drives the fixing rod 305 to slide within the long plate 304 until the fixing rod 305 is inserted into the fixing hole 308. This achieves the effect of disassembling and installing the connecting ladder 2, avoiding the situation where the ladder body 1 is difficult to disassemble due to different crane installation height requirements, making it difficult to install the ladder according to the crane requirements and thus hindering the operation. This improves the practicality of the device.

[0021] When the safety buckle connecting plate 41 is needed, push the safety buckle connecting plate 41 to slide on the surface of the slide groove of the ladder body 1 until it is pulled out. Then push the limit rod 45 to slide in the support plate 44 until the limit rod 45 is inserted into the limit hole 47. When it is not needed, pull the limit rod 45 to slide in the support plate 44. The limit rod 45 drives the baffle 46 until the baffle 46 touches the support plate 44. The rebound force of the second spring 43 drives the auxiliary plate 42. The auxiliary plate 42 drives the safety buckle connecting plate 41 to slide in the slide groove of the ladder body 1 until it is reset. This achieves the effect of improving the safety of the staff and avoids the situation where the safety rope of the staff is difficult to attach to the professional attachment point because there is no safety rope attachment point on the surface of the ladder body 1. This improves the practicality of the device.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
