Technical Field
[0001] This utility model relates to the field of hoisting device technology, and in particular to a steel formwork hoisting device suitable for high-altitude operations. Background Technology
[0002] In today's booming construction engineering field, high-rise buildings, large bridges, towering chimneys and other high-altitude operation projects are increasing. In these projects, steel formwork has become an indispensable tool for constructing concrete structures due to its many advantages such as high strength, good rigidity, excellent forming quality and reusability.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: With the continuous development and innovation of construction engineering technology, construction processes and requirements are also constantly changing. The existing fixed-spacing hoisting block design greatly limits the versatility and flexibility of hoisting devices, and cannot meet diverse construction needs. For example, in some projects that adopt new construction processes, special hoisting and installation methods may be required for steel formwork. However, the existing hoisting devices cannot adjust the hoisting block spacing and cannot adapt to these new construction requirements, forcing construction companies to repurchase or modify hoisting equipment, which increases project costs and management difficulties. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of limiting the versatility and flexibility of the hoisting device. Therefore, we propose a steel formwork hoisting device suitable for high-altitude operations.
[0005] To achieve the above objectives, this application adopts the following technical solution: a steel formwork hoisting device suitable for high-altitude operations, comprising a hoisting device body, a drive mechanism installed at the bottom of the hoisting device body, a hoisting plate installed at the bottom of the drive mechanism, an adjustment groove opened at the bottom of the hoisting plate, hoisting blocks slidably connected to both sides inside the adjustment groove, control grooves opened at both ends of the hoisting blocks, adjustment blocks slidably connected inside the control grooves, a through groove opened at the top of the adjustment block, a through block fixedly connected to the top of the adjustment block, and straight grooves opened at both ends of the bottom of the hoisting plate, with several slots opened at one end of each straight groove.
[0006] Preferably, guide grooves are provided at both ends of the adjustment groove, and guide blocks are fixedly connected to both ends of the lifting block, with the surface of the guide block slidingly connected to the inside of the guide groove.
[0007] Preferably, a return spring is fixedly connected to the side of the adjusting groove away from the lifting block, and a top block is fixedly connected to the side of the return spring close to the lifting block.
[0008] Preferably, the size of the through block is adapted to the size of the slot, and the surface of the through block is inserted into the interior of the slot.
[0009] Preferably, a storage spring is fixedly connected to the side of the adjusting block near the inside of the control slot, and the side of the storage spring away from the adjusting block is fixedly connected to the inside of the control slot.
[0010] Preferably, sliding grooves are provided on both sides of the control groove, and sliding blocks are fixedly connected to both sides of the adjustment block, with the surface of the sliding block slidingly connected to the inside of the sliding groove.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] In this invention, when the operator pushes the adjusting block into the control slot, the adjusting block compresses the storage spring to store force, and causes the through block to release its limit from the slot. After the operator adjusts the appropriate position of the lifting block, the through block is aligned with the inside of the slot and the adjusting block is released. Under the action of the rebound force of the storage spring, the through block is quickly inserted into the inside of the slot, which quickly limits the lifting block and prevents the lifting block from shifting during use, thus improving the stability of the device.

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.
[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a steel formwork hoisting device suitable for high-altitude operations, including a hoisting device body 1, a drive mechanism 2 installed at the bottom of the hoisting device body 1, a hoisting plate 3 installed at the bottom of the drive mechanism 2, an adjustment groove 4 opened at the bottom of the hoisting plate 3, hoisting blocks 5 slidably connected to both sides inside the adjustment groove 4, control grooves 6 opened at both ends of the hoisting block 5, an adjustment block 7 slidably connected inside the control groove 6, a through groove 8 opened at the top of the adjustment block 7, a through block 9 fixedly connected to the top of the adjustment block 7, straight grooves 10 opened at both ends of the bottom of the hoisting plate 3, and a plurality of slots 11 opened at one end inside the straight groove 10.
[0022] Specifically: The staff pushes the adjusting block 7 into the control slot 6, causing the adjusting block 7 to move the through block 9 and release the limit between the through block 9 and the slot 11. At the same time, the limit of the hoisting block 5 is released. The staff adjusts the hoisting block 5 to the appropriate position and re-limits the through block 9 and the slot 11, thus completing the adjustment of the distance between the hoisting blocks 5.
[0023] Reference Figure 5 As shown in this embodiment: guide grooves 12 are provided at both ends of the adjustment groove 4, and guide blocks 13 are fixedly connected to both ends of the lifting block 5. The surface of the guide block 13 is slidably connected to the inside of the guide groove 12.
[0024] Specifically, the guide block 13 slides inside the guide groove 12, ensuring the stability of the lifting block 5 sliding inside the adjustment groove 4, avoiding the phenomenon of the lifting block 5 shifting or shaking during the sliding process, and further improving the stability and safety of the lifting device body 1 during use.
[0025] Reference Figure 5 As shown in this embodiment: a return spring 14 is fixedly connected to the side of the adjusting groove 4 away from the lifting block 5, and a top block 15 is fixedly connected to the side of the return spring 14 close to the lifting block 5.
[0026] Specifically: When the operator brings the lifting block 5 into contact with the top block 15, the lifting block 5 pushes the top block 15 to compress and store the return spring 14. When the operator releases the limit of the lifting block 5, the return spring 14 releases the stored force to push the top block 15 to reset, and drives the lifting block 5 to reset quickly. This makes it easy for the operator to quickly adjust the lifting block 5 and improves the practicality of the device.
[0027] Reference Figure 5 As shown, in this embodiment: the size of the through block 9 is adapted to the size of the slot 11, and the surface of the through block 9 is inserted into the interior of the slot 11;
[0028] Specifically, by inserting the through block 9 into the slot 11, the staff can limit and fix the lifting block 5, preventing the lifting block 5 from shaking inside the adjustment slot 4, thus ensuring the stability of the lifting block 5. At the same time, it is convenient for the staff to quickly assemble and disassemble the lifting block 5, improving the convenience of the device.
[0029] Reference Figure 5 As shown, in this embodiment: a storage spring 16 is fixedly connected to the side of the adjusting block 7 near the inside of the control groove 6, and the side of the storage spring 16 away from the adjusting block 7 is fixedly connected to the inside of the control groove 6.
[0030] Specifically: When the operator pushes the adjusting block 7 into the control slot 6, the adjusting block 7 compresses the storage spring 16 to store force, and drives the through block 9 to release the limit between it and the slot 11. After the operator adjusts the appropriate position of the lifting block 5, the through block 9 is aligned with the inside of the slot 11 and the adjusting block 7 is released. Under the action of the rebound force of the storage spring 16, the through block 9 is quickly inserted into the inside of the slot 11, which quickly limits the lifting block 5 and prevents the lifting block 5 from shifting during use, thus improving the stability of the device.
[0031] Reference Figure 5 As shown in this embodiment: sliding grooves 17 are provided on both sides of the control groove 6, and sliding blocks 18 are fixedly connected to both sides of the adjustment block 7. The surface of the sliding block 18 is slidably connected to the inside of the sliding groove 17.
[0032] Specifically: When the operator pushes the adjusting block 7 to move inside the control groove 6, the adjusting block 7 drives the sliding blocks 18 on both sides to slide inside the slide groove 17. The slide groove 17 plays a limiting and guiding role for the sliding blocks 18, so that the adjusting block 7 will not deviate during the movement, further improving the stability of the movement of the adjusting block 7.
[0033] Working principle: The operator pushes the adjusting block 7 into the control slot 6, causing the adjusting block 7 to move the through block 9 and release the limit between the through block 9 and the slot 11. At the same time, the limit of the hoisting block 5 is released. The operator adjusts the hoisting block 5 to the appropriate position and re-limits the through block 9 and the slot 11, thus completing the adjustment of the distance between the hoisting blocks 5.
[0034] 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.
