A medium-voltage hoisting cable for super high-rise buildings and its production and installation process

Abstract

This invention discloses a medium-voltage hoisting cable for ultra-high-rise buildings and its production and installation process, relating to the field of hoisting technology. It includes a hoisting cable and a hoisting head located at the cable's head for auxiliary hoisting. The invention addresses potential uncertainties during cable hoisting, such as hoisting pauses. Instead of using an electric drive mechanism for auxiliary unwinding, construction personnel manually unwind the cable by controlling a handwheel. This allows for control of the unwinding speed based on actual hoisting conditions, making the hoisting process smoother. By disassembling and assembling the fixing screws, the connection status between side frame two, side frame one, and the main roller can be changed based on the outer bearing and support bearing, thereby enabling the roller assembly to be used in both the cable production and hoisting processes.

Description

Technical Field

[0001] This invention relates to the field of hoisting technology, specifically to a medium-voltage hoisting cable for ultra-high-rise buildings and its production and installation process. Background Art

[0002] The suspended cable is a special type of cable. The vertical section of the cable has three steel wire ropes and is equipped with a lifting disc. The steel wire ropes are covered with fan-shaped plastic and twisted with the three cable cores. The horizontal section of the cable does not have steel wire ropes.

[0003] With the above-mentioned structural features, the hoisting cable is not limited by length and weight, and can reliably support its own weight, thus solving the problem that ordinary cables are easily damaged by their own weight during long-distance vertical laying.

[0004] Nevertheless, specialized lifting equipment must be used for lifting cables. The lifting equipment consists of three parts: lifting rings, lifting equipment body, and connecting bolts (steel wire rope anchors). The lifting equipment is manufactured by the manufacturer. In addition, to ensure the smooth lifting of cables, an electrical shaft should be installed, and a shaft-penetrating shuttle should be made accordingly.

[0005] Given that cables are typically transported after being properly wound into coils at the factory, the aforementioned hoisting process also requires unwinding the cables first, and it involves a lot of equipment and is too cumbersome. Furthermore, the limitations of cable use must be considered, as ordinary cables are not suitable. To solve these problems, we propose a medium-voltage hoisting cable for ultra-high-rise buildings and its production and installation process. Summary of the Invention

[0021] Preferably, it also includes manufacturing process S100 and installation process S200;

[0022] The production process S100 includes the following steps:

[0023] S101, Wire drawing: Using copper or aluminum as raw materials, at room temperature, a wire drawing machine is used to pass through one or more drawing die holes to reduce the cross-section, increase the length, and improve the strength.

[0024] S102 Annealing: Copper monofilaments are heated to a certain temperature and recrystallized to improve their toughness and reduce their strength, so as to meet the requirements of wires and cables for conductive cores.

[0027] S105. Packaging: After the cable has cooled, it is wound up. Operators place the auxiliary device downstream of the cable production line according to the actual needs of the construction workers, and then install fixing screws to put the roller group in the winding state. Then, the transmission mechanism is activated to drive the dual-purpose rollers for winding.

[0028] The installation process S200 includes the following steps:

[0029] S201. Cable assembly: Before hoisting the cable, the construction personnel first install the base plate on the lower end of the mounting seat based on the mounting screw, and then insert the end of the hoisting cable between the two clamps and tighten it with two fastening screws. After the hoisting cable is tightened, the lifting lug is attached to the lower end of the hook.

[0030] S202, State Transition: In order to allow the hoisting cable to be unwound normally, the construction personnel first unscrew the fixing screws from ear plate one and ear plate two. At this time, the main roller can rotate relative to side frame one and side frame two.

[0031] S203, Auxiliary hoisting: After the roller group has changed state, the construction personnel first start the winch attached to the hook, and the hoisting cable is lifted vertically by the hook based on the lifting head. At the same time, the construction personnel drive the main roller to rotate synchronously by turning the handwheel, so as to unwind the hoisting cable.

[0032] Compared with the prior art, the present invention provides a medium-voltage hoisting cable for super high-rise buildings and its production and installation process, which has the following beneficial effects:

[0033] 1. The medium-voltage hoisting cable for ultra-high-rise buildings and its production and installation process, through the setting of auxiliary devices, considering the uncertainties that may exist in the hoisting process, such as hoisting being paused, instead of using an electric drive mechanism for auxiliary unwinding, construction personnel manually unwind the hoisting cable by controlling the handwheel, so as to control the unwinding speed of the hoisting cable according to the actual hoisting situation, making the hoisting process of the hoisting cable smoother.

[0034] 2. The medium-voltage hoisting cable for ultra-high-rise buildings and its production and installation process, by setting up a dual-purpose roller, can disassemble and assemble the fixing screws, thereby changing the connection status of the side frame two, side frame one and the main roller based on the outer bearing and the support bearing, so as to realize the change of the use status of the roller group, making the roller group applicable to the production process and hoisting process of the hoisting cable.

[0035] 3. The medium-voltage hoisting cable for ultra-high-rise buildings and its production and installation process, through the setting of a limiting cable frame, four limiting pulleys are arranged in a ring on the four sides of the hoisting cable. In this way, the hoisting cable can move reasonably within an appropriate space during the hoisting process, so as to avoid excessive deviation of the hoisting cable during the hoisting process and affect the hoisting progress.

[0036] 4. The medium-voltage hoisting cable for ultra-high-rise buildings and its production and installation process, through the setting of a limiting cable frame, based on the second limiting pulley in the vertical direction of the roller group, due to its structural position, if the hoisting speed of the hoisting cable is too fast and does not match the unwinding speed of the roller group, the hoisting cable may be overstretched. During this process, the limiting pulley will provide appropriate support for the hoisting cable to buffer the force on the hoisting cable, which can effectively avoid the situation where the hoisting cable may be damaged due to excessive stretching.

[0056] To make the technical means, creative features, and achieved objectives and effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Specific Implementation Example 1

[0058] To address the shortcomings of existing technologies, such as Figure 1 As shown, the present invention provides a medium-voltage hoisting cable for super high-rise buildings, wherein the hoisting head 2 is detachably connected to the head end of the hoisting cable 1;

[0059] The hoisting cable 1 is wrapped around the outer wall of the mechanical output end of the auxiliary device 3, and the head end of the hoisting cable 1 is connected to the lower end of the hook 4 through the hoist head 2.

[0060] Specifically, such as Figure 2 As shown, a lifting head 2 for medium-voltage cable hoisting in a super high-rise building has a lower end of a lifting lug 21 fixedly connected to the upper end of a mounting base 22, and the upper end of a mounting screw 23 threadedly connected to the mounting base 22. The mounting screw 23 is opened from the upper end of a base plate 24, and two fastening screws 26 are respectively inserted into the left and right sides of the lower end of the base plate 24 and rotatably connected thereto. The two fastening screws 26 pass through the two ends of two clamping plates 25 and are threadedly connected thereto.

[0061] It should be noted that before hoisting cable 1, the hoisting head 2 must be installed at the hoisting head end of the hoisting cable 1. During the installation of the hoisting head 2, the hoisting head 2 must be assembled first.

[0062] The construction personnel first install the lifting lug 21 to the head end of the mounting base 22, and then screw the base plate 24 to the bottom end of the mounting base 22 based on the mounting screw 23 and tighten it. After the lifting lug 21 and the mounting screw 23 are assembled with the mounting base 22, the lifting cable 1 and the lifting head 2 can be assembled.

[0063] During the assembly of the hoisting cable 1 and the hoisting head 2, the construction workers first loosen the two fastening screws 26. At this time, the two clamping plates 25 can slide relative to each other at the lower end of the installation screw 23. The construction workers then adjust the two clamping plates 25.

[0064] Once the spacing is appropriate, the construction personnel insert the lifting head end of the lifting cable 1 between the two clamps 25, and then rotate and tighten the two fastening screws 26 between the two clamps 25 to complete the assembly of the lifting head 2.

[0065] like Figure 3 , 4 As shown, a medium-voltage hoisting cable for super high-rise buildings and an auxiliary device 3 for its production and installation process are provided. The lower ends of the dual-purpose roller 31 and the transmission mechanism 32 are both fixedly connected to the upper end of the base 33, and the lower end of the limiting cable frame 34 is fixedly connected to the upper end of the dual-purpose roller 31. The mechanical output end of the transmission mechanism 32 is fixedly connected to the mechanical input end of the dual-purpose roller 31.

[0066] It should be noted that the present invention is a medium-voltage hoisting cable for super high-rise buildings and its production and installation process. After the hoisting head 2 and the hoisting cable 1 are assembled, the hoisting cable 1 must be hoisted through the auxiliary device 3. Before that, the hoisting cable 1 should be wound into the dual-purpose roller 31 after processing.

[0067] During the hoisting of the lifting cable 1, the construction personnel move the auxiliary device 3 as a whole to a suitable position based on the base 33 and place it stably so that the limiting cable frame 34 is opposite to the hook 4. Then, the head end of the lifting cable 1 equipped with the lifting head 2 extends from the bottom end of the limiting cable frame 34 to the hook 4 and is hooked thereto.

[0068] After the head of the hoisting cable 1 is connected to the hook 4 based on the hoisting head 2, the construction personnel control the dual-purpose roller 31 to put the dual-purpose roller 31 in the unwinding state. The construction personnel then start the winch attached to the hook 4. After that, the construction personnel control the dual-purpose roller 31 to unwind in order to cooperate with the hook 4 to achieve hoisting.

[0069] Specifically, and such as Figure 7 As shown, in a medium-voltage hoisting cable for a super high-rise building and an auxiliary device 3 for its production and installation process, there is a limiting cable frame 34, with four limiting pulleys 342 rotatably connected to four wheel frames 343, and the four wheel frames 343 are fixedly connected to the four sides of the upper end of the limiting cable frame 34. The lower ends of the two sides of the support frame 341 are fixedly connected to the upper middle part of the front and rear ends of the roller frame 311.

[0070] It should be noted that the present invention is a medium-voltage hoisting cable for super high-rise buildings and its production and installation process. By setting a limiting cable frame 34, if the position of the hoisting cable 1 deviates during the hoisting process, after the hoisting cable 1 comes into contact with a limiting pulley 342, the limiting pulley 342 can slide on the corresponding wheel frame 343, thereby achieving the limiting and ensuring the normal hoisting transmission of the hoisting cable 1.

[0071] Among them, four limiting pulleys 342 are arranged in a ring on the four sides of the hoisting cable 1. In this way, the hoisting cable 1 can move reasonably within an appropriate space during the hoisting process, so as to avoid excessive deviation of the hoisting cable 1 during the hoisting process and affect the hoisting process.

[0072] Based on the second limiting pulley 342 of the roller group 312 in the vertical direction, due to its structural position, if the lifting speed of the lifting cable 1 is too fast and does not match the unwinding speed of the roller group 312, the lifting cable 1 may be overstretched. During this process, the limiting pulley 342 will provide appropriate support for the lifting cable 1 to buffer the force on the lifting cable 1, which can effectively avoid the situation where the lifting cable 1 may be damaged due to excessive stretching.

[0073] Specifically, such as Figure 5 , 6 As shown, a dual-purpose roller 31 and a transmission mechanism 32 are used in the auxiliary device 3 for the production and installation process of a medium-voltage hoisting cable for super high-rise buildings. The two ends of the roller group 312 are respectively rotatably connected to the upper ends of the front and rear sides of the roller frame 311.

[0074] The main body of the drive motor 321 is fixedly connected to the front end of the main body of the reducer 322, and the mechanical output end of the drive motor 321 is fixedly connected to the mechanical input end of the reducer 322.

[0075] The mechanical output end of the reducer 322 is fixedly connected to one end of the transmission shaft 323, and the gear 324 is fixedly connected to the outer wall of the section of the transmission shaft 323 on the side away from the reducer 322 inside the roller frame 311. The gear ring 325 is fixedly connected to the tail end of the roller group 312, and the gear 324 meshes with the gear ring 325.

[0076] The protective outer frame 327 and the toothed ring 325 are structurally compatible, and the protective outer frame 327 is fixedly connected to the rear end of the roller frame 311. The main body of the ratchet assembly 326 is fixedly connected to one side of the rear end of the roller frame 311. The drive shaft 323 passes through the front end of the roller frame 311 to its rear end, and the rear end of the drive shaft 323 is fixedly connected to the mechanical input end of the ratchet assembly 326.

[0077] Furthermore, for example Figures 8-11 As shown, in a medium-voltage hoisting cable for a super high-rise building and an auxiliary device 3 for its production and installation process, the roller group 312 of the dual-purpose roller 31 has two support bearings 3124 respectively embedded in the middle of two side frames 3123, and the outer rings of the two support bearings 3124 are fixedly connected to the side frame 3122 and the side frame 3123 respectively.

[0078] Side frame 1 3122 and side frame 2 3123 are rotatably connected to the two ends of the main roller 3121 through their corresponding support bearings 3124. The opposite ends of the two connecting shafts 3127 are fixedly connected to the inner rings of the two support bearings 3124, and the handwheel 3128 is fixedly connected to the outer end of the corresponding connecting shaft 3127.

[0079] The outer ring of one of the outer bearings 3125 adjacent to side frame 1 3122 is fixedly connected to the middle of the opposite side of side frame 1 3122, and the inner ring of the other bearing 3125 extends to the roller frame 311 and is fixedly connected thereto. The outer ring of the other outer bearing 3125 adjacent to side frame 2 3123 extends to the roller frame 311 and is fixedly connected thereto. Furthermore, the inner wall of the inner ring of the bearing 3125 is fixedly connected to the outer wall of the corresponding inner bearing 3126 through side frame 1 3122.

[0080] The outer walls of the two connecting shafts 3127 are fixedly connected to the inner walls of the inner rings of the two inner bearings 3126 respectively, and the fixing screws 3131 are threadedly connected to the ear plate 1 3129 and ear plate 2 3130 respectively.

[0081] It should be noted that the present invention is a medium-voltage hoisting cable for super high-rise buildings and its production and installation process. Through the set roller group 312, during the hoisting process of the hoisting cable 1, the construction personnel first change the roller group 312 to the unwinding state.

[0082] During the process of changing the usage status of roller group 312, the construction personnel first unscrew the fixing screw 3131 from ear plate one 3129 and ear plate two 3130, so that ear plate one 3129 and ear plate two 3130 are no longer connected. At this time, the main roller 3121 can rotate between the two side frames two 3123 through the two support bearings 3124.

[0083] Because of the structure of the ratchet assembly 326, the side frame 3122 connected to the toothed ring 325 cannot rotate. The construction personnel rotate the handwheel 3128 in the unwinding direction of the hoisting cable 1. As the handwheel 3128 rotates, it drives the inner ring of the corresponding support bearing 3124 to rotate through the corresponding connecting shaft 3127, which indirectly drives the main roller 3121 to rotate synchronously, so as to unwind the hoisting cable 1 wound on the outer wall of the main roller 3121.

[0084] In view of the uncertainties that may exist during the hoisting of cable 1, such as the hoisting being paused, instead of using an electric drive mechanism to assist in unwinding, the construction personnel manually unwind cable 1 by controlling the handwheel 3128, so as to control the unwinding speed of cable 1 according to the actual hoisting situation, making the hoisting process of cable 1 smoother. Specific Implementation Example 2

[0086] Based on the production steps of the lifting cable 1, the lifting cable 1 is directly wound and packaged after processing. However, for the lifting requirements of the lifting cable 1, the coil of the lifting cable 1 needs to be unwound first in order to better lift the lifting cable 1. In fact, saving the intermediate unwinding process can greatly improve the lifting efficiency of the lifting cable 1. Therefore, this embodiment is proposed:

[0087] like Figure 5 , 6 As shown, a medium-voltage hoisting cable for super high-rise buildings and its production and installation process are described. It should be noted that, based on the above embodiment one, through the set dual-purpose roller 31 and transmission mechanism 32, the construction personnel can place the auxiliary device 3 at the downstream discharge port of the cable factory production line to rewind the cable as needed, or place the auxiliary device 3 on the large hoisting cable 1 purchased in advance to change the rewind of the hoisting cable 1. Before that, the roller group 312 must be changed to the rewinding state.

[0088] During the process of changing the usage status of roller group 312, the construction personnel can screw the fixing screw 3131 into ear plate 1 3129 and ear plate 2 3130 and tighten them. After being connected by fixing screw 3131, the main roller 3121, together with side frame 1 3122 and side frame 2 3123, can rotate synchronously with the roller frame 311 through two external bearings 3125.

[0089] Construction workers start the drive motor 321, which drives the reducer 322 to output synchronously and drives the gear 324 to rotate synchronously through the drive shaft 323. During the rotation of the gear 324, the gear ring 325 rotates relative to it, and the gear ring 325 drives the side frame 3122 connected to it to rotate synchronously. Indirectly, the roller group 312 rotates to realize the winding of the hoisting cable 1.

[0090] By disassembling and assembling the fixing screw 3131, the connection status between the side frame 2 3123, the side frame 1 3122 and the main roller 3121 can be changed based on the outer bearing 3125 and the support bearing 3124, thereby realizing the change of the usage status of the roller group 312, so that the roller group 312 can be used in the production process and hoisting process of the hoisting cable 1.

[0091] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

2. A process for manufacturing and installing lifting cables using the lifting cable auxiliary device described in claim 1, characterized in that: It also includes manufacturing process S100 and installation process S200; The production process S100 includes the following steps: S101, Wire drawing: Using copper or aluminum as raw materials, at room temperature, a wire drawing machine is used to pass through one or more drawing die holes to reduce the cross-section, increase the length, and improve the strength. S102 Annealing: Copper monofilaments are heated to a certain temperature and recrystallized to improve their toughness and reduce their strength, so as to meet the requirements of wires and cables for conductive cores. S103, Stranding: In order to improve the flexibility of wires and cables and facilitate laying and installation, multiple single wires are stranded together to form a copper conductor; S104. Extrusion: Using a plastic extruder to cover each layer of the cable with a protective layer or insulation layer; S105, Packaging: After the cable cools down, the cable is wound up. According to the actual needs of the construction personnel, the operator places the auxiliary device (3) downstream of the cable production line, and then installs fixing screws (3131) to make the roller group (312) in the winding state, and then starts the transmission mechanism (32) to drive the dual-purpose roller (31) to wind up. The installation process S200 includes the following steps: S201, Cable assembly: Before hoisting the cable, the construction personnel first install the base plate (24) on the lower end of the mounting base (22) based on the mounting screw (23), and then insert the head end of the hoisting cable (1) between the two clamps (25) and tighten it with two fastening screws (26). After the hoisting cable (1) is tightened, the lifting lug (21) is hung on the lower end of the hook (4). S202, State Transformation: In order to enable the hoisting cable (1) to be unwound normally, the construction personnel first unscrew the fixing screw (3131) from the ear plate one (3129) and ear plate two (3130). At this time, the main roller (3121) can rotate relative to the side frame one (3122) and side frame two (3123). S203, Auxiliary hoisting: After the state change of the roller group (312) is completed, the construction personnel first start the winch attached to the hook (4) and drive the hoisting cable (1) to rise vertically through the hook (4) based on the hoisting head (2). At the same time, the construction personnel drive the main roller (3121) to rotate synchronously by turning the handwheel (3128) to realize the unwinding of the hoisting cable (1).
