Description

Technical Field

[0001] This invention belongs to the field of cable laying technology for ultra-high-rise vertical shafts, specifically a vertical cable laying and hoisting device for ultra-high-rise vertical shafts with a safe self-locking structure. Background Technology

[0002] Shaft cables are a general term for power cables, communication cables, and signal cables laid in the vertical shafts of buildings. They are mainly used to connect ground and underground equipment and are suitable for scenarios such as high-rise buildings, hydropower stations, and underground substations. They need to be laid vertically in dedicated cable wells or shaft passages. Shaft cable laying is the laying of cables through vertical passages inside buildings or underground projects. It is mainly used to solve power transmission problems. Vertical laying of shaft cables refers to the vertical installation of cables in the shaft passage and the operation of vertically hoisting the cables to the designated position in the shaft using lifting machinery. It is mainly used in scenarios such as high-rise buildings, hydropower stations, and underground substations.

[0003] However, most common existing hoisting devices are connected by hooks. However, after the hooks are connected, they are prone to shaking due to external forces, which can cause them to come off. Moreover, the space in the shaft is relatively small, and the size of the shaft opening needs to be accurately measured before hoisting. This process is cumbersome and time-consuming. Furthermore, when the cable is vertically hoisted to the designated position in the shaft, it needs to be locked for laying. Simply stopping the motor cannot lock the hoisting device, which can lead to errors and reduce the effectiveness of the hoisting device. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical cable laying and hoisting device with a safe self-locking structure for ultra-high-rise vertical shafts in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: A vertical cable laying and hoisting device for ultra-high-rise vertical shafts with a safe self-locking structure includes a U-shaped frame. A fixing plate is installed on the lower inner surface of the U-shaped frame. A first drive motor is provided on the outer surface of the fixing plate. A threaded shaft is connected to the inner surface of the first drive motor. A bearing is provided on one end surface of the threaded shaft. A threaded sleeve is installed on the outer surface of the threaded shaft. A connecting plate is fixedly installed on the lower surface of the threaded sleeve. Side plates are fixedly connected to the lower two sides of the connecting plate. A second drive motor is provided on the outer surface of the side plates. An installation shaft is fixedly connected to the inner surface of the second drive motor. A winding roller is installed on the outer surface of the installation shaft. A wire rope is fixedly connected to the outer surface of one end of the winding roller.

[0006] By adopting the above technical solution, the installation of a fixing plate makes the inner hoisting device more stable during operation. The installed first drive motor drives the inner threaded shaft to rotate during operation, thereby allowing the threaded sleeve on its surface to move and adjust to align with the position of the shaft opening. This allows the lower wire rope and hook to enter the shaft completely without the need for workers to accurately measure the shaft opening size first. The bearings installed prevent the threaded shaft from shifting during rotation, ensuring stability and safety. The installation of a connecting plate allows it to move and adjust together with the upper threaded sleeve. The installed side plates ensure the stable operation of the inner winding roller, preventing swaying that could destabilize the entire hoisting device. The installed second drive motor rotates the mounting shaft, which in turn rotates the inner winding roller. This rotation extends the steel wire rope connected to one end, allowing it to adapt to shafts of different heights. Conversely, the second drive motor moves in the opposite direction to retract the wire rope, slowly pulling it back into the winding roller. This facilitates cable laying for construction workers and improves the overall safety of the device, making it both practical and safe.

[0007] In a preferred embodiment, an installation block is fixedly connected to the bottom surface of the wire rope, a hook is installed on the lower surface of the installation block, an arc-shaped stop bar is provided on the front surface of the hook, and a spring is installed on the bottom surface of the arc-shaped stop bar.

[0008] By adopting the above technical solution, the cable and the hook are connected to each other. After the cable and the hook are connected, the arc-shaped stop bar can close the notch of the hook, thereby effectively preventing the cable from falling off during hoisting, thus ensuring stability and safety.

[0009] In a preferred embodiment, a limiting rod is connected to the upper inner surface of the fixing plate, a limiting sleeve is provided on the outer surface of the limiting rod, and a connecting block is installed on the lower surface of the limiting sleeve.

[0010] By adopting the above technical solution, the threaded sleeve can be prevented from rotating under the limiting action of the limiting sleeve and the limiting rod, so that it can only move on the threaded shaft. The installed connecting block can make the connection between the limiting sleeve and the threaded sleeve more stable, so that it has the functions of limiting and stability.

[0011] In a preferred embodiment, a support base is fixedly connected to the lower surface of the U-shaped frame, a support leg is installed on the lower surface of the support base, and an anti-slip pad is provided on the lower surface of the support leg.

[0012] By adopting the above technical solutions, the installation of support bases can make the hoisting device above operate more stably. Installing multiple support legs can distribute some of the pressure on the support base above, preventing deformation of the support base due to long-term use. Installing anti-slip pads can make the hoisting device above more stable during use, preventing danger caused by shaking, and making it stable and protective.

[0013] In a preferred embodiment, a storage groove is formed on the inner surface of the lower center of the support base, an adjustment plate is installed on the inner surface of the storage groove, a caster wheel is provided on the lower surface of the adjustment plate, and a threaded groove is formed on the inner surface of the upper part of the adjustment plate.

[0014] By adopting the above technical solution, the storage slot can better accommodate the internal moving components, thereby improving the overall aesthetics of the rotating shaft. The installation of the adjustment plate allows for height adjustment to accommodate the casters. The installation of the casters makes it easier for workers to adjust the direction and move the device. The threaded groove allows the inner adjusting screw to rotate, making it both aesthetically pleasing and easy to use.

[0015] In a preferred embodiment, an adjusting screw is connected to the inner surface of the threaded groove, a turntable is provided on the upper surface of the adjusting screw, and a non-slip grip is installed on the upper surface of the turntable.

[0016] By adopting the above technical solution, the operator can rotate the non-slip handle to drive the turntable on the lower surface to rotate, which in turn drives the adjusting screw to rotate, allowing the lower adjusting plate to be adjusted in height. Rotating in the opposite direction can cause the adjusting plate to retract into the storage slot, making it versatile and storable.

[0017] In a preferred embodiment, positioning plates are fixedly installed on the lower two sides of the connecting plate, a rotating wheel is provided on the outer surface of the positioning plate, and a threaded post is connected to the inner surface of the rotating wheel.

[0018] By adopting the above technical solution, the inner locking mechanism can be operated more stably by installing the positioning plate. The operator can rotate the wheel to drive the inner threaded column to rotate, thereby locking the front arc-shaped clamping plate on the winding roller. Rotating the wheel in the opposite direction can disengage the arc-shaped clamping plate from the surface of the winding roller, making it versatile and adaptable.

[0019] In a preferred embodiment, a threaded cylinder is connected to the outer surface of the threaded column, and an arc-shaped clamping plate is fixedly connected to the top surface of the threaded cylinder. The inner surface of the arc-shaped clamping plate is provided with anti-slip ridges.

[0020] By adopting the above technical solution, the rotation of the threaded column can drive the connected threaded cylinder to rotate, thereby causing the threaded cylinder to move the inner arc-shaped clamping plate until the arc-shaped clamping plate is completely aligned with the winding roller and then locked. The anti-slip ridges on the inner surface of the arc-shaped clamping plate can prevent the winding roller from shaking and causing the cable to be unable to be laid, thus making it practical and comprehensive.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, the installation of a fixing plate ensures more stable operation of the inner hoisting device. The installed first drive motor rotates the inner threaded shaft during operation, allowing the threaded sleeve on its surface to move and adjust to align with the shaft opening. This allows the lower wire rope and hook to enter the shaft completely without requiring precise measurement of the shaft opening dimensions. The included bearings prevent deviation during the rotation of the threaded shaft, ensuring stability and safety. The installation of a connecting plate allows for coordinated movement and adjustment with the upper threaded sleeve. The side plate ensures the inner winding roller operates more stably, preventing swaying that could destabilize the entire hoisting device. The installed second drive motor rotates the mounting shaft, causing the inner winding roller to rotate as well. This rotation extends the steel wire rope connected to one end, adapting it to shafts of varying heights. Conversely, the second drive motor moves in the opposite direction to retract the wire rope, allowing it to be slowly pulled back into the winding roller. This facilitates cable laying for construction workers and enhances the overall safety of the device, making it both practical and safe. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Reference Figure 1-4 A vertical cable laying and hoisting device for ultra-high-rise shafts with a safety self-locking structure includes a U-shaped frame 1. A fixing plate 18 is installed on the lower inner surface of the U-shaped frame 1. A first drive motor 19 is installed on the outer surface of the fixing plate 18. A threaded shaft 13 is connected to the inner surface of the first drive motor 19. A bearing 12 is installed on one end surface of the threaded shaft 13. A threaded sleeve 14 is installed on the outer surface of the threaded shaft 13. A connecting plate 21 is fixedly installed on the lower surface of the threaded sleeve 14. By installing the fixing plate 18, the hoisting device on the inner side can operate more stably. The installed first drive motor 19 can drive the threaded shaft 13 connected on the inner side to rotate during operation, thereby allowing the threaded sleeve 14 on its surface to move and adjust to align with the position of the shaft opening. This allows the steel wire rope 25 and hook 27 below to enter the shaft completely without the need for workers to accurately measure the shaft opening size first. The bearing 12 can prevent the threaded shaft 13 from deviating during rotation, thus ensuring stability and safety.

[0026] Reference Figure 1-4Side plates 20 are fixedly connected to the lower two sides of the connecting plate 21. A second drive motor 23 is provided on the outer side of the side plate 20. A mounting shaft 22 is fixedly connected to the inner side of the second drive motor 23. A winding roller 24 is installed on the outer side of the mounting shaft 22. A wire rope 25 is fixedly connected to the outer side of one end of the winding roller 24. The connecting plate 21 allows for movement and adjustment together with the threaded sleeve 14 above. The installed side plate 20 ensures more stable operation of the inner winding roller 24, preventing instability caused by swaying. The installed second drive motor 23 drives the mounting shaft 22 to rotate, thereby rotating the inner winding roller 24. The rotation of the winding roller 24 extends the steel wire rope 25 connected at one end, adapting it to shafts of different heights. Conversely, the second drive motor 23 moves in the opposite direction, causing the inner winding roller 24 to retract the wire rope, allowing the extended steel wire rope 25 to slowly return to the winding roller 24. This facilitates cable laying for construction workers and improves the safety of the overall device, making it both practical and safe.

[0027] Reference Figure 4-5 A mounting block 26 is fixedly connected to the bottom surface of the wire rope 25. A hook 27 is installed on the lower surface of the mounting block 26. An arc-shaped stop bar 29 is provided on the front surface of the hook 27, and a spring 28 is installed on the bottom surface of the arc-shaped stop bar 29. By connecting the cable to the hook 27, the arc-shaped stop bar 29 can close the notch of the hook 27 after the cable is connected, thereby effectively preventing the cable from falling off during hoisting, thus ensuring stability and safety.

[0028] Reference Figure 3 A limiting rod 17 is connected to the upper inner surface of the fixing plate 18, and a limiting sleeve 16 is provided on the outer surface of the limiting rod 17. A connecting block 15 is installed on the lower surface of the limiting sleeve 16. By installing the limiting sleeve 16 and the limiting rod 17, the threaded sleeve 14 will not rotate under its limiting action, thus allowing it to move only on the threaded shaft 13. The installed connecting block 15 makes the connection between the limiting sleeve 16 and the threaded sleeve 14 more stable, giving it both limiting and stability.

[0029] Reference Figure 1A support base 2 is fixedly connected to the lower surface of the U-shaped frame 1. Support legs 4 are installed on the lower surface of the support base 2, and anti-slip pads 5 are provided on the lower surface of the support legs 4. Installing the support base 2 makes the hoisting device above more stable to operate and use. Installing multiple support legs 4 can distribute some of the pressure on the upper support base 2, preventing the support base 2 from deforming due to long-term use. Installing anti-slip pads 5 makes the hoisting device above more stable during use, preventing danger caused by shaking, and making it stable and protective.

[0030] Reference Figure 1-2 A storage groove 3 is provided on the inner surface of the lower center of the support base 2. An adjustment plate 10 is installed on the inner surface of the storage groove 3. A caster wheel 11 is provided on the lower surface of the adjustment plate 10, and a threaded groove 9 is provided on the upper inner surface of the adjustment plate 10. The storage groove 3 allows for better storage of the internal moving components, thereby improving the overall aesthetics of the rotating shaft. The adjustment plate 10 allows for height adjustment to accommodate the caster wheel 11. The caster wheel 11 makes it easier for operators to adjust the direction and move the device. The threaded groove 9 allows the inner adjusting screw 8 to rotate, combining aesthetics with ease of movement.

[0031] Reference Figure 2 An adjusting screw 8 is connected to the inner surface of the threaded groove 9. A turntable 7 is provided on the upper surface of the adjusting screw 8, and a non-slip handle 6 is installed on the upper surface of the turntable 7. When the operator holds the non-slip handle 6 and rotates it, it can drive the turntable 7 on the lower surface to rotate, which in turn drives the adjusting screw 8 to rotate, thereby adjusting the height of the lower adjusting plate 10. Rotating in the opposite direction can retract the adjusting plate 10 into the storage slot 3, making it versatile and storable.

[0032] Reference Figure 4-6 Positioning plates 30 are fixedly installed on the lower two sides of the connecting plate 21. A rotating wheel 33 is provided on the outer surface of the positioning plate 30, and a threaded post 32 is connected to the inner surface of the rotating wheel 33. By installing the positioning plate 30, the inner locking mechanism can operate more stably. By rotating the rotating wheel 33, the operator can drive the inner threaded post 32 to rotate, thereby locking the front arc-shaped clamping plate 34 onto the winding roller 24. Rotating the rotating wheel 33 in the opposite direction can disengage the arc-shaped clamping plate 34 from the surface of the winding roller 24, making it versatile and adaptable.

[0033] Reference Figure 6A threaded cylinder 31 is connected to the outer surface of the threaded column 32, and an arc-shaped clamping plate 34 is fixedly connected to the top surface of the threaded cylinder 31. The inner surface of the arc-shaped clamping plate 34 is provided with anti-slip ridges 35. The rotation of the threaded column 32 can drive the connected threaded cylinder 31 to rotate, thereby causing the threaded cylinder 31 to drive the inner arc-shaped clamping plate 34 to move until the arc-shaped clamping plate 34 is completely aligned with the winding roller 24 and locked. The anti-slip ridges 35 on the inner surface of the arc-shaped clamping plate 34 can prevent the winding roller 24 from shaking, which would prevent the cable from being laid, making it practical and comprehensive.

[0034] The implementation principle of this invention, a vertical cable laying hoisting device with a safe self-locking structure for ultra-high-rise shafts, is as follows: The installation of the fixing plate 18 ensures more stable operation of the hoisting device inside. The installed first drive motor 19 rotates the threaded shaft 13 connected internally during operation, allowing the threaded sleeve 14 on its surface to move and adjust to align with the shaft opening. This allows the lower wire rope 25 and hook 27 to be fully inserted into the shaft without requiring precise measurement of the shaft opening dimensions. The bearing 12 prevents deviation during the rotation of the threaded shaft 13, ensuring stability and safety. The installation of the connecting plate 21 allows it to connect with the upper threaded... The sleeve 14 is moved and adjusted together. The installed side plate 20 can make the inner winding roller 24 more stable in operation and use, preventing the overall hoisting device from being unstable due to shaking. The installed second drive motor 23 can drive the mounting shaft 22 to rotate, thereby making the inner winding roller 24 rotate. The rotation of the winding roller 24 can make the steel wire rope 25 connected at one end continuously extend, so as to adapt to vertical shafts of different heights. Conversely, by running the second drive motor 23 in the opposite direction, the inner winding roller 24 can be wound up, so that the extended steel wire rope 25 can be slowly returned to the winding roller 24, which facilitates the laying of cables by construction personnel and improves the safety of the overall device, making it practical and safe.
