Description

Technical Field

[0001] This application relates to the field of self-lifting equipment, and in particular to a suspended self-lifting material platform. Background Art

[0002] For large silo structures, a steel structure with an outer concrete frame structure is usually adopted to improve the fire protection level of the structure and the requirements for the roof structure. Since the internal silo is cylindrical or conical and has a relatively high height, the external concrete structure is basically a frame column and frame beam structure without floor slabs.

[0003] During the construction of the silo, the required steel can be transported by a crane or manually, and then the steel is stacked on the top of the silo. Since the top area of the silo is small and continuous construction is required, a discharge platform needs to be built on the side wall of the silo; the discharge platform is usually built with steel pipes. On the one hand, as the height increases, the height of the steel pipe discharge platform also increases, which will increase the time wasted in building the steel pipes and increase the usage of steel pipes. On the other hand, when building the steel pipe discharge platform, as the height of the silo increases, the slenderness ratio of the steel pipe discharge platform gradually increases. To ensure structural safety, the steel pipe discharge platform needs to be built with a sufficient width, which greatly wastes labor and the usage of steel pipes, and such a design greatly occupies manpower and material resources and delays the construction period, not meeting the requirements of engineering construction and urgently needing improvement.

[0004] Therefore, the inventor provides a suspended self-lifting material platform Summary of the Invention

[0005] In order to reduce the manpower and material resources occupied by building the discharge platform and improve the construction efficiency of the silo, this application provides a suspended self-lifting material platform.

[0006] The suspended self-lifting material platform provided by this application adopts the following technical solutions:

[0007] A suspended self-lifting material platform includes a fixing frame arranged on the top of the silo and a discharge platform arranged at the bottom of the fixing frame. A driving device for pulling the discharge platform to lift is arranged on the fixing frame; a plurality of counterweights for balancing the gravity of the discharge platform are arranged on the fixing frame. A first connecting seat is arranged at one end of the fixing frame away from the silo, a second connecting seat is arranged at the other end of the fixing frame away from the first connecting seat, a support rod is arranged on the fixing frame, and a rope loop is arranged on the support rod. The rope loop is connected to the first connecting seat and the second connecting seat.

[0008] By adopting the above technical solution, during operation, the unloading platform can be lifted by the driving device to meet the material transportation work, and the unloading platform can also be stopped to meet the purpose of stacking materials on the unloading platform; in cooperation with the counterweight and the connecting rope loop, the fixing frame can be more stably installed on the top of the silo, improving the stability of using the fixing frame; with such a design, it can not only meet the need for material lifting, improve the convenience of material transportation, but also use the unloading platform to stack materials, reducing the use of manpower and material resources in the prior art, making material stacking more convenient and improving the convenience of using the material platform. And a counterweight is used to balance the gravity of the unloading platform, so that the unloading platform can transport materials more stably. In cooperation with the rope loop, the two ends of the fixing frame can be balanced, reducing the situation of the fixing frame bending. And by using the rope loop, when pulling the first connecting seat, the rope loop provides an upward inclined tension on the one hand and a tension approaching the horizontal on the other hand, so that it can not only better overcome the gravity of the unloading platform, but also further balance the bending moment force generated by the unloading platform, reducing the occurrence of damage to the fixing frame. And by using the rope loop, an annular structure can be formed. During installation, only the rope loop needs to be passed through the first connecting seat and the second connecting seat and erected on the top of the support rod, and then the two ends of the rope loop are locked to realize the fixation of the rope loop, improving the convenience of using the rope loop, and reducing the connection structure between the rope loop and the first connecting seat and the second connecting seat, so that the possibility of loosening at the connection of the connecting rope can be reduced, improving the stability of using the rope loop.

[0009] Preferably, the driving device includes a plurality of winders fixed on the fixing frame, a winding rope is wound on the winder, and the winding rope is connected to the unloading platform.

[0010] By adopting the above technical solution, the unloading platform can be lifted by the winding of the winder, improving the convenience of lifting and lowering the unloading platform.

[0011] Preferably, a plurality of lifting lugs are arranged on both sides of the unloading platform, the lifting lugs are connected to the winding rope, a platform fence is arranged on the unloading platform, a switch plate is rotatably connected to one side of the unloading platform close to the silo, a positioning pin is arranged on the switch plate, a positioning hole inserted and matched with the positioning pin is opened on the platform fence, and the positioning pin is inserted and matched with the positioning hole for locking the switch plate.

[0012] By adopting the above technical solution, the platform fence can be used to restrict the materials on the unloading platform, avoiding the possibility of materials falling off the unloading platform and causing high-altitude falling objects, thereby improving the stability of using the unloading platform. In cooperation with the switch door, materials can be placed and taken more conveniently, improving the convenience of using the unloading platform.

[0013] Preferably, the fixing frame includes a plurality of supporting seats, a rotating seat is rotatably arranged on the supporting seat, and a cross bar is slidably connected to the rotating seat; a fixing seat is arranged at one end of the cross bar close to the counterweight, the counterweight is installed on the fixing seat, a plurality of limiting holes inserted and matched with the cross bar are formed on one side of the fixing seat close to the cross bar, a limiting block is arranged on one side of the cross bar close to the fixing seat, an inclined groove is formed on the upper side of the limiting block, the inclined groove is inclined downward along the direction away from the cross bar, an inclined block abutted against the inclined groove is arranged on the upper wall of the limiting hole, and a locking component for locking the limiting block is arranged on the fixing seat; the driving device includes a winch fixed on the fixing seat, a tightening rope is wound on the winch, a guide wheel is arranged on a section of the cross bar away from the fixing seat, and the tightening rope bypasses the guide wheel and is connected to the unloading platform.

[0014] By adopting the above technical solution, during use, the unloading platform is pulled to the top of the silo by the winch, the locking component is opened, and in cooperation with the pulling of the winch, the guide wheel and the cross bar are pulled to move closer to the fixing seat. Under the action of the gravity of the unloading platform and in cooperation with the supporting seat, the inclined block can always abut against the inclined groove. The cooperation between the inclined block and the inclined groove can achieve a damping effect, so that the cross bar moves slowly; there is a certain friction between the guide wheel and the tightening rope. There is also a certain friction between the connection of the guide wheel and the cross bar. When the tension of the tightening rope on the side close to the winch is only slightly greater than that of the tightening rope located below the guide wheel, the guide wheel can be prevented from rotating, so that the cross bar can be pulled towards the fixing seat, and then the unloading platform can be pulled towards the silo. Since the silo is a cylinder or a cone, there is still a certain distance between the unloading platform and the top of the silo when the unloading platform reaches the top. Such a design can enable the unloading platform to be better placed on the top of the silo, improving the convenience of using the unloading platform. And only the winch simultaneously satisfies the lifting and horizontal movement of the unloading platform, reducing the number of driving devices used for the material platform and improving the convenience of using the material platform.

[0015] Preferably, the locking component includes a plugging hole formed at the bottom side of the limiting hole, a positioning block is slidably connected in the plugging hole, a driving member for driving the positioning block to slide is arranged in the fixing seat, and a plurality of positioning grooves inserted and matched with the positioning block are formed at the bottom side of the limiting block.

[0016] By adopting the above technical solution, inserting the positioning block into the positioning groove can lock the limiting block. After the cross bar moves in place towards the fixing seat, the positioning block is inserted into another positioning groove, thereby locking the limiting block, reducing the movement of the cross bar, and improving the stability of using the material platform.

[0017] Preferably, the cross-sectional area of the positioning block gradually decreases along the direction close to the limiting block.

[0018] By adopting the above technical solution, when there is a certain deviation between the positioning groove and the positioning block, the positioning block can be inserted into the positioning groove more conveniently, improving the convenience and stability of fixing the limiting block.

[0019] Preferably, a connecting rod is provided at one end of the limiting block away from the cross bar, and the connecting rod penetrates through the fixing seat.

[0020] By adopting the above technical solution, when the connection is inserted out of the fixing seat, after the materials on the unloading platform are unloaded, the worker pushes the connecting rod to move towards the fixing seat, and under the action of the inclined block and the inclined groove, the cross bar is reset, improving the convenience of using the material platform.

[0021] Preferably, a limiting block is provided on the outer wall of the connecting rod, and a hand-held groove for facilitating the worker to hold is provided on the outer wall of the limiting block.

[0022] By adopting the above technical solution, using the limiting block can limit the displacement of the connecting rod, thereby achieving the effect of limiting the cross bar, reducing the separation of the limiting block from the limiting hole, and improving the stability of using the limiting block.

[0023] Preferably, a sliding hole for inserting and matching with the cross bar is provided on the rotating seat, and a plurality of rotating wheels are rotatably connected to the bottom of the sliding hole, and the axial direction of the rotating wheels is perpendicular to the sliding direction of the cross bar.

[0024] By adopting the above technical solution, the cross bar can slide more smoothly on the rotating seat, improving the convenience of using the cross bar.

[0025] Preferably, an auxiliary support rod is provided on one side of the support seat away from the fixing seat, an auxiliary seat is provided on the auxiliary support rod, and an auxiliary groove for inserting and matching with the cross bar is provided on the auxiliary seat.

[0026] By adopting the above technical solution, using the auxiliary support rod can support the cross bar. When the cross bar moves horizontally, it will move away from the auxiliary groove. Since the bending moment generated by the unloading platform after horizontal movement will gradually decrease, it can meet the support requirements of the cross bar. When the cross bar moves away from the fixing seat, the cross bar will gradually move closer to the auxiliary groove. Thus, when the cross bar completely fits into the auxiliary groove, it can limit the further movement of the cross bar, thereby achieving the effect of limiting the movement distance of the cross bar and can support the cross bar, improving the convenience and stability of using the cross bar.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The driving device is used to pull the unloading platform for lifting, which can not only meet the need of material lifting, improve the convenience of material transportation, but also use the unloading platform to stack materials, reducing the use of human and material resources in the prior art, making it more convenient to stack materials and improving the convenience of using the material platform. Moreover, counterweights are used to balance the gravity of the unloading platform, enabling the unloading platform to transport materials more stably. In cooperation with the rope loop, the two ends of the fixing frame can be balanced, reducing the occurrence of bending of the fixing frame. And with the rope loop, when pulling the first connecting seat, the rope loop provides an upward inclined pulling force on the one hand and a nearly horizontal tension on the other hand, so that not only can the gravity of the unloading platform be better overcome, but also the bending moment force generated by the unloading platform can be further balanced, reducing the occurrence of damage to the fixing frame. And with the rope loop, a circular structure can be formed. During installation, only the rope loop needs to pass through the first connecting seat and the second connecting seat and be erected on the top of the support rod, and then the two ends of the rope loop are locked to achieve the fixation of the rope loop, improving the convenience of using the rope loop and reducing the connection structure between the rope loop and the first connecting seat and the second connecting seat, so that the possibility of loosening at the connection of the connecting rope can be reduced, improving the stability of using the rope loop;

[0029] 2. The winch is used to pull the unloading platform to the top of the silo, the locking component is opened, and in cooperation with the pulling of the winch, the guide wheel and the cross bar are pulled to move closer to the fixed seat. Under the action of the gravity of the unloading platform, the inclined block can always abut against the inclined groove, and the cooperation between the inclined block and the inclined groove can play a damping effect, making the cross bar move slowly; there is a certain friction between the guide wheel and the tensioning rope. There is also a certain friction between the connection of the guide wheel and the cross bar. When the tension of the tensioning rope on the side close to the winch is only slightly greater than the tensioning rope located below the guide wheel, the guide wheel can be made not to rotate, so that the cross bar can be pulled towards the fixed seat, and thus the unloading platform can be pulled towards the silo. Since the silo is a cylinder or a cone, there is still a certain distance between the unloading platform and the top of the silo when it reaches the top. Such a design can enable the unloading platform to be better placed on the top of the silo, improving the convenience of using the unloading platform. And only through the winch, the lifting and horizontal movement of the unloading platform are simultaneously satisfied, reducing the number of driving devices used for the material platform and improving the convenience of using the material platform;

[0030] 3. Inserting the positioning block into the positioning groove can lock the limiting block. After the cross bar moves in place towards the fixed seat, the positioning block is inserted into another positioning groove to lock the limiting block, thereby reducing the movement of the cross bar and improving the stability of using the material platform.

Detailed implementation manners

[0037] The following further describes the present application in detail Figures 1-5 with reference to the attached drawings.

[0038] Embodiment 1 of the present application discloses a suspended self-lifting material platform.

[0039] Embodiment 1:

[0040] Refer to Figure 1, a suspended self-lifting material platform, including a fixing frame 19 fixed to the top of the silo and a discharging platform 2 suspended at the bottom of the fixing frame 19. A driving device for pulling the discharging platform 2 to lift and lower is installed at one end of the fixing frame 19 away from the silo. A plurality of counterweight blocks 7 are installed at one end of the fixing frame 19 away from the driving device. The counterweight blocks 7 are rectangular blocks made of concrete materials, and the counterweight blocks 7 are used to balance the gravity of the discharging platform 2. A first connecting seat 13 is rotatably connected to one side of the fixing frame 19 away from the silo. A first rotating wheel 12 is rotatably connected to the first connecting seat 13. A second connecting seat 17 is welded and fixed to one end of the fixing frame 19 away from the first connecting seat 13. A second rotating wheel 16 is arranged on the second connecting seat 17. A support rod 15 is welded and fixed to the fixing frame 19. A third rotating wheel 14 is rotatably connected to the support rod 15. A rope loop 10 is installed on the third rotating wheel 14. The rope loop 10 is made of steel wire rope. The rope loop 10 sequentially passes through the first rotating wheel 12 and the second rotating wheel 16 and is fixed together end to end.

[0041] During operation, the two ends of the fixing frame 19 are balanced by the rope loop 10, so that the situation of damage to the fixing frame 19 can be reduced. On the one hand, the rope loop 10 pulled obliquely towards the third rotating wheel 14 can balance the gravity of the discharging platform 2 and reduce the bending moment force on the fixing frame 19. In cooperation with the rope loop 10 connected to the first rotating wheel 12 and the second rotating wheel 16, the rope loop 10 is approximately horizontally arranged and has a certain distance from the fixing frame 19, which can form a certain bending moment, so that the bending moment force generated by the discharging platform 2 can be better balanced, and the stability of using the fixing frame 19 can be improved. On the other hand, the rope loop 10 connected end to end can make the rope loop 10 have only one connection position, which can reduce the fixing structure of the rope loop 10 compared with being respectively connected to the first rotating wheel 12 and the second rotating wheel 16, reduce the loosening of the rope loop 10 at the fixed position, and improve the stability of using the rope loop 10. When in use, it not only meets the function of lifting and transporting materials, but also provides space for stacking materials. Compared with the prior art, it can reduce the use of steel pipes, greatly reduce the use of manpower and material resources, improve the convenience of using the material platform, and can improve the construction efficiency of the silo to a certain extent.

[0042] The driving device includes two winding devices 11 fixed on the fixing frame 19. The winding devices 11 are winches, and a winding rope 8 is wound on the winding devices 11. The winding rope 8 is connected to the discharging platform 2. The discharging platform 2 is a rectangular plate composed of multiple steel materials. Four lifting lugs 4 are arranged on the discharging platform 2. The lifting lugs 4 are welded and fixed in pairs on the peripheral side of the discharging platform 2. A connecting block is connected near the discharging platform 2 on the winding rope 8, and two connecting ropes 9 are connected to the bottom of the connecting block. The connecting ropes 9 are fixedly connected to the lifting lugs 4. A platform fence 1 is fixed by bolts on the peripheral side of the discharging platform 2. A switch plate 3 is rotatably connected to one side of the discharging platform 2 close to the silo. The switch plate 3 is a rectangular frame composed of multiple steel materials. A positioning pin 46 is slidably connected to the switch plate 3. A positioning hole 45 inserted and matched with the positioning pin 46 is opened on the platform fence 1. The positioning pin 46 is inserted and matched with the positioning hole 45 to realize the control of the opening and closing of the switch plate 3.

[0043] An installation seat 6 is arranged at one end of the fixing frame 19 far from the winch 21. The installation seat 6 is placed on the cylinder body. Multiple installation columns 18 are fixed on the installation seat 6. An installation hole inserted and matched with the installation column 18 is vertically penetrated through the upper side of the counterweight block 7. A handle 5 is fixed on the side wall of the counterweight block 7. With such a design, the counterweight block 7 can be installed according to the weight of the discharging platform 2 and the materials, improving the convenience of using the counterweight block 7.

[0044] The implementation principle of Embodiment 1 is as follows: During work, the fixing frame 19 is placed on the top of the silo, and then the counterweight block 7 is installed on the installation column 18. The discharging platform 2 is driven to lift by the winding device 11. When it moves to the top, the discharging platform 2 serves as a platform for stacking materials, so that the materials in the silo can be stacked more conveniently. With such a design, the materials can be stacked more conveniently during the construction of the silo, reducing the use of human and material resources in the prior art, making the material stacking more convenient, improving the convenience of using the material platform, and improving the efficiency of constructing the silo.

[0045] Embodiment 2:

[0046] Refer to Figure 2 and Figure 3, A suspended self-lifting material platform, which is different from that of Embodiment 1 in that the fixing frame 19 includes two support seats 25. A rotating seat 26 is rotatably connected to the support seat 25. A cross bar 27 is slidably connected to the rotating seat 26, and the cross bar 27 is a rectangular tube. One end of the cross bar 27 close to the counterweight 7 is provided with a fixing seat 20. The fixing seat 20 is a rectangular frame. The mounting seat 6 is fixed to both sides of the fixing seat 20. The counterweight 7 is detachably mounted on the mounting seat 6. Two limiting holes 28 which are in plug-in fit with the two cross bars 27 are opened on one side of the fixing seat 20 close to the cross bar 27. The limiting holes 28 are rectangular holes. A limiting block 29 is fixedly welded to one end of the cross bar 27 close to the fixing seat 20. The limiting block 29 is a rectangular block. An inclined groove 37 is opened on the upper side of the limiting block 29. The inclined groove 37 is inclined downward in the direction away from the cross bar 27. An inclined block 36 which abuts against the inclined groove 37 is integrally formed on the upper side of the limiting hole 28. A locking assembly for locking the limiting block 29 is mounted on the fixing seat 20. The driving device includes a winch 21 fixed to the fixing seat 20. The winch 21 is a hoist. A tensioning rope 23 is wound on the winch 21. A connecting cross plate 38 is fixed to one end of the cross bar 27 away from the fixing seat 20. The connecting cross plate 38 is used to connect the two cross bars 27. A guide wheel 22 is bolted to the connecting cross plate 38. The tensioning rope 23 is wound around the guide wheel 22 and connected to the unloading platform 2. A sliding hole 34 which is in plug-in fit with the cross bar 27 is opened on the rotating seat 26. The sliding hole 34 is a rectangular hole. A plurality of rotating wheels 33 are rotatably connected to the bottom of the sliding hole 34. The axial direction of the rotating wheels 33 is perpendicular to the sliding direction of the cross bar 27

[0047] With such a design, the winch 21 not only realizes the lifting of the unloading platform 2, but also can pull the lifting platform to move closer to the silo, improving the convenience of using the unloading platform 2. And since the silo is a cylinder or a cone, there is a certain distance between the unloading platform 2 and the side wall of the silo during lifting, ensuring that the unloading platform 2 will not scrape against the side wall of the silo. When the unloading platform 2 reaches the top, there is still a certain distance from the top of the silo. Moving the unloading platform 2 closer to the silo can enable the staff to more conveniently take the materials on the unloading platform 2. And only by the pulling of the winch 21 can the lifting and horizontal movement of the unloading platform 2 be realized, reducing the number of driving devices used for the material platform and improving the convenience of using the material platform.

[0048] Refer to Figure 3 and Figure 5 , The locking assembly includes a plugging hole opened at the bottom of the limiting block 29. A positioning block 40 is slidably connected in the plugging hole. The positioning block 40 is in a boss shape, and its cross-sectional area gradually decreases in the direction close to the limiting block 29. A driving member 41 for driving the positioning block 40 to slide is installed in the fixing seat 20. The driving member 41 is a driving electric cylinder. A positioning groove 39 which is in plug-in fit with the positioning block 40 is opened on the bottom side of the limiting block 29.

[0049] Reference Figure 3 and Figure 5 At one end of the limiting block 29 away from the cross bar 27, a connecting rod 42 is in threaded fit connection. The connecting rod is a cylindrical rod, and the connecting rod 42 penetrates through the fixed seat 20. A limiting stop block 44 is fixed on the outer wall of the connecting rod 42 away from the limiting seat. The cooperation between the limiting stop block 44 and the fixed seat 20 can limit the moving distance of the limiting block 29 and improve the stability of using the limiting block 29. A hand-held groove 43 for facilitating the staff to hold is formed on the limiting stop block 44. By the staff pushing the connecting rod 42 to move closer to the fixed seat 20, under the action of the inclined groove 37 and the inclined block 36, the limiting block 29 can be reset more conveniently.

[0050] Reference Figure 3 and Figure 4 At one end of the support seat 25 away from the fixed seat 20, an auxiliary support rod 24 is welded and fixed. The auxiliary support rod 24 is made of a square tube and is inclined. An auxiliary seat 31 is welded and fixed on the auxiliary support rod 24. An auxiliary groove 30 for inserting and cooperating with the cross bar 27 is formed on the auxiliary seat 31. With such a design, on the one hand, when the cross bar 27 moves away from the fixed seat 20, the rotation of the cross bar 27 can be restricted, thereby restricting the movement of the cross bar 27 and improving the stability of using the cross bar 27. On the other hand, the auxiliary support rod 24 can support the cross bar 27, improve the anti-bending moment ability of the cross bar 27, and improve the convenience and stability of using the cross bar 27.

[0051] The implementation principle of Embodiment 2 is as follows: The difference from Embodiment 1 is that when the unloading platform 2 is lifted to the specified height, the positioning block 40 slides out of the positioning groove 39, and under the action of the winding machine 21, the cross bar 27 is pulled to move closer to the fixed seat 20. The inclined groove 37 and the inclined block 36 provide damping for the movement of the cross bar 27. There is a certain friction between the guide wheel 22 and the tensioning rope 23, and there is also a certain friction between the connection of the guide wheel 22 and the cross bar 27. When the tension of the tensioning rope 23 on the side close to the winding machine 21 is only slightly greater than that of the tensioning rope 23 located below the guide wheel 22, the guide wheel 22 can be made not to rotate, so that the cross bar 27 can be pulled to move towards the fixed seat 20, so that the unloading platform 2 moves towards the silo, realizing the horizontal movement of the unloading platform 2, so that the staff can use the unloading platform 2 more conveniently and improve the efficiency of silo construction.

[0052] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
