Description

Technical Field

[0001] This invention relates to the field of corridor construction technology, specifically to a hoisting device and construction method for a fan-shaped asymmetrical integrated steel structure corridor. Background Technology

[0002] Currently, due to the large size, weight, and quantity of the connecting corridors, as well as the need for installation at high altitudes, the construction method currently used is mostly to assemble them on the ground, then use a crane to lift the entire connecting corridor to the floor where it needs to be installed, and finally weld them together after they are suspended in place.

[0003] During construction, the primary method for existing systems is to use four cranes to simultaneously lift the connecting corridor at its four corners. However, due to the weight of the corridor, crane malfunctions or cable breakages can occur during lifting, leading to serious accidents. This is especially true when lifting asymmetrical corridors such as fan-shaped ones. Unlike rectangular corridors, the center of gravity of a fan-shaped corridor is not at the center of the four lifting cables, resulting in excessive weight on one side of the crane during lifting, thus increasing the risk of accidents. Furthermore, airflow disturbances during lifting can cause the corridor to sway, further exacerbating this problem. While some technologies use additional protective devices to further lock the cables, the unpredictable nature of accidents and the inability to pinpoint the location of cable breakage mean that these additional cables are mostly installed near the cranes, only addressing cable slippage caused by crane malfunctions, not preventing breakages in the center. Summary of the Invention

[0004] The technical problem of the present invention is to provide a hoisting device and construction method for a fan-shaped asymmetric integrated steel structure corridor, which can rise synchronously with the corridor during lifting and can lock the corridor in time in case of an accident.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hoisting device for a fan-shaped asymmetric integrated steel structure corridor and its construction method, including a slide rail and a support frame that is limited and slidably connected to the slide rail. A suspension frame is fixedly connected to one end of the support frame away from the slide rail. A through hole for steel cable to pass through is opened on the suspension frame. Multiple sets of locking devices are provided on the suspension frame.

[0006] The locking device consists of two sets of rope pulleys symmetrically arranged on the suspension frame. Each rope pulley includes a rotating frame, a rotating shaft rotatably connected to the rotating frame, a locking wheel fixedly connected to the rotating shaft, and a secondary wheel rotatably connected to the rotating frame. Multiple support blocks are arranged in a circular array around the axis of the rotating shaft on the arc-shaped contour of the rotating shaft. A pawl is slidably connected to the support block for limiting. A limit pin is provided at the position where the rotating frame connects to the rotating shaft. A spring is provided in the support block to allow the pawl to move away from the rotating shaft.

[0007] One set of rotating frames for the sheave section is fixedly connected to the suspension frame, and another set of rotating frames for the sheave section is fixedly connected to a sliding rod that is slidably connected to the suspension frame. The end of the sliding rod away from the rotating frame is fixedly connected to a connecting plate that enables multiple sliding rods to be fixedly connected to each other. The sliding rod is also provided with a spring assembly that enables the sliding rod to move in a direction away from the rotating frame. The rotating frame of the sheave section with the sliding rod is located above the rotating frame of the other set of rotating frames for the sheave section.

[0008] As a further embodiment of the present invention, two sets of mirror-arranged braking groups are fixedly connected to the side of the support frame away from the suspension frame. The braking group includes multiple locking holes opened on the slide rail, and a slide table that is slidably connected to the slide rail. A mounting platform is fixedly connected to the slide table, and a brake pawl is slidably connected to the mounting platform. A wedge block is slidably connected to the mounting platform, which allows the brake pawl to move outward toward the mounting platform. A fixing rod is fixedly connected to the support frame. A sliding rod is slidably connected to the fixing rod on the side of the wedge block away from the mounting platform. A spring that allows the wedge block to return to its original position toward the mounting platform is provided between the fixing rod and the wedge block. A limiting pin is also slidably connected to the support frame. The end of the sliding rod away from the wedge block is hooked onto the limiting pin. A triggering mechanism is also provided on the support frame that can pull out the limiting pin to disengage the sliding rod from the limiting pin.

[0009] As a further embodiment of the present invention, the triggering mechanism includes a pull rope fixedly connected to a limiting pin, and one end of the pull rope away from the limiting pin is fixedly connected to a rotating frame on which a slide rod is provided.

[0010] As a further embodiment of the present invention, a pusher frame is also fixedly connected to the support frame, and two mirror-shaped grippers are slidably connected within the pusher frame.

[0011] As a further embodiment of the present invention, the push frame is provided with springs fixedly connected to the claws at both ends. The claws are fixedly connected to a locking rod on their adjacent sides. The push frame is fixedly connected with a limiting pin three, which passes through the sliding locking rod. The end of the limiting pin three away from the sleeve is slidably connected to a wedge two. The limiting pin three is provided with a spring plate that can reset the wedge two towards the outside of the limiting pin three. The push frame is provided with a through hole communicating with the sleeve. The lower side of the push frame is slidably connected to a top pin. The sleeve is provided with a spring that can move the limiting pin three away from the top pin.

[0012] As a further embodiment of the present invention, anti-slip strips are provided on the locking wheel and the auxiliary wheel.

[0013] As a further embodiment of the present invention, pulleys are provided on both sides of the slide table.

[0014] As a further aspect of the present invention, the specific steps of the construction method for the hoisting device of the fan-shaped asymmetric integrated steel structure corridor are as follows:

[0015] Step 1: Fix multiple sliding rails arranged in a straight line to the exterior wall of the building. Then install the support frame inside the sliding rails. Next, pass the crane's steel cable from the top of the suspension frame downwards through the suspension frame. During the process, the steel cable needs to pass through each locking wheel and auxiliary wheel from top to bottom in sequence. Finally, fix it to the connecting corridor.

[0016] Step 2: During the hoisting process, as the connecting corridor rises, when the connecting corridor moves to the position of the pusher, the connecting corridor will push the pusher to push the support frame to move upward at the same time. The support frame will slide upward in the slide rail via the slide table.

[0017] Step 3: When a crane accident occurs, the connecting corridor will pull the steel cable downwards. At this time, the pawl will abut against the limit pin 2, so the locking wheel cannot rotate, thus locking the steel cable and preventing it from sliding down. At the same time, the rotating frame equipped with a sliding rod will pull the locking wheel downwards after the steel cable is locked. The rotating frame equipped with the sliding rod will slide downwards on the suspension frame through the sliding rod. The rotating frame equipped with the sliding rod will move to the side of the rotating frame fixed to the suspension frame away from the steel cable, forming an interlaced shape, so that part of the steel cable is wrapped around the locking wheel. Thus, the rotating frame fixed to the suspension frame will hook the steel cable, thereby further locking it.

[0018] Step 4: As the rotating frame with the sliding rod slides, it pulls the rope, which pulls the limit pin out of the slide rail. Without the limit pin, the sliding rod moves away from the limit pin under the action of the spring, which pushes the wedge block into the mounting platform. The wedge block then pushes the brake pawl towards the locking hole, so that the brake pawl can engage in the locking hole. Thus, the brake pawl brakes the slide platform, preventing it from sliding further on the slide rail.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Because it is equipped with a chuck and a limit pin, as well as a rotating frame and a sliding rod, the steel cable can be locked by the locking wheel in the event of an accident. The misalignment of the two sets of rope wheels further improves the locking force and the suspension force on the steel cable, thereby ensuring the locking effect on the steel cable.

[0021] 2. At the same time, due to the presence of a braking device, the connecting corridor can be locked immediately by pulling the rope, and the locking position is the closest point to the connecting corridor.

[0022] 3. The two grippers will fasten to both sides of the steel frame of the connecting corridor, thus holding the connecting corridor tightly and preventing it from tilting. This ensures that the connecting corridor is raised horizontally, guarantees the stability of the lifting process, and facilitates subsequent welding. At the same time, it can adapt to steel frames of different specifications and has an automatic clamping function. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0036] Please see Figures 1 to 9 The present invention provides a technical solution: a hoisting device for a fan-shaped asymmetric integrated steel structure corridor and its construction method, including a slide rail 03 and a support frame 01 that is limited and slidably connected to the slide rail 03. A suspension frame 02 is fixedly connected to one end of the support frame 01 away from the slide rail 03. A through hole for steel cable to pass through is opened on the suspension frame 02. Multiple sets of locking devices are provided on the suspension frame 02.

[0037] The locking device consists of two sets of rope pulleys symmetrically arranged on the suspension frame 02. Each rope pulley includes a rotating frame 10, a rotating shaft 15 rotatably connected to the rotating frame 10, a locking wheel 11 fixedly connected to the rotating shaft 15, and a secondary wheel 12 rotatably connected to the rotating frame 10. Multiple support blocks 23 are arranged in a circular array around the axis of the rotating shaft 15 on the arc-shaped contour of the rotating shaft 15. A pawl 24 is slidably connected to the support block 23. A limit pin 30 is provided at the position where the rotating frame 10 connects to the rotating shaft 15. A spring is provided in the support block 23 to allow the pawl 24 to move away from the rotating shaft 15.

[0038] One set of rotating frames 10 for the sheave section is fixedly connected to the suspension frame 02, and another set of rotating frames 10 for the sheave section is fixedly connected to a slide rod 09 that is slidably connected to the suspension frame 02 with a limit. The end of the slide rod 09 away from the rotating frame 10 is fixedly connected to a connecting plate 13 that can fix multiple slide rods 09 to each other. The slide rod 09 is also provided with a spring assembly that can move the slide rod 09 in a direction away from the rotating frame 10. The rotating frame 10 for the sheave section with the slide rod 09 is located above the other set of rotating frames 10 for the sheave section.

[0039] In use, slide rail 03 can be installed according to different situations. For example, when constructing a connecting corridor at a relatively low height, only one slide rail 03 can be used. The slide rail 03 and support frame 01 are fixedly installed, and the slide rail 03 is installed above the construction position of the connecting corridor. Then, the steel cable lowered from the crane is passed between the suspension frame 02, the locking wheel 11, and the auxiliary wheel 12, and then fixed to the connecting corridor. A device should be installed at each of the four corners of the connecting corridor. During lifting, the four cranes work synchronously to lift the connecting corridor. The cranes will pull the steel cable to lift the connecting corridor until it reaches the required height. When raised to the required position, because the distance between the suspension frame 02 and the connecting corridor is relatively short, the length of the steel cable between them is also short. This makes the cable less prone to slippage and ensures it remains confined by the suspension frame 02, preventing the connecting corridor from easily swaying. In the event of a crane accident or a breakage of the steel cable above the suspension frame 02, the connecting corridor will initially begin to fall under gravity. The movement of the connecting corridor will pull the steel cable downwards. At this time, because the steel cable is clamped between the locking wheel 11 and the auxiliary wheel 12, the downward movement of the cable will cause the locking wheel 11 to rotate clockwise (which can be combined with...). Figure 3At this point, the pawl 24 will be blocked by the limit pin 30, thus preventing it from rotating further and locking the steel cable to prevent it from sliding down. At the same time, the rotating frame 10 equipped with the slide bar 09 will pull the locking wheel 11 to move the rotating frame 10 downward after the steel cable is locked. As a result, the rotating frame 10 equipped with the slide bar 09 will slide downward on the suspension frame 02 at an angle via the slide bar 09. The rotating frame 10 equipped with the slide bar 09 will move to the side of the rotating frame 10 fixedly connected to the suspension frame 02 away from the steel cable, forming an interlaced shape, so that part of the steel cable is wrapped around the locking wheel 11. Thus, the rotating frame 10 fixedly connected to the suspension frame 02 can hook the steel cable, thereby further locking it.

[0040] When constructing a connecting corridor on a high-rise building, a track consisting of sliding rails 03 can be installed on the exterior wall of the building. At this time, the support frame 01 and the sliding rail 03 are slidably connected. Therefore, when the connecting corridor rises, it will also drive the support frame 01 to move upward. As a result, the support frame 01 will rise in a straight line on the track consisting of sliding rails 03. At this time, the support frame 01 is always close to one end of the connecting corridor and can always limit the sliding rail 03 through the suspension frame 02. Therefore, when constructing a connecting corridor on a high-rise building, it can be ensured that the connecting corridor is always in a stable state during the construction process and will never slide, thereby greatly improving safety.

[0041] Because of the suspension frame 02, when the support frame 01 is fixedly installed on the slide rail 03, the suspension frame 02 can reduce the swaying of the steel cable and reduce the increased inertia of the connecting corridor due to swaying. This reduces the excessive load on the crane caused by excessive inertia, thus protecting the normal operation of the crane. Reducing swaying also stabilizes the connecting corridor, preventing it from hindering welding and reducing the possibility of collisions with the building during lifting. When the support frame 01 can slide within the slide rail 03, for construction on higher floors, since the crane is installed above the floor where installation is required, the steel cable between the crane and the connecting corridor is relatively long and unrestrained. This allows for smoother lifting. During the lifting process, the connecting corridor is prone to swaying. While the support frame 01 slides within the slide rail 03, the suspension frame 02 rises synchronously with the connecting corridor, maintaining a consistent distance from it. This ensures the cable length between the suspension frame 02 and the connecting corridor remains consistent, allowing the suspension frame 02 to consistently limit the cable length between the connecting corridor and the suspension frame 02, thus ensuring the stability of the connecting corridor during lifting. Furthermore, during welding after lifting, the stability of the connecting corridor is maintained, preventing swaying and facilitating the welding process. Additionally, in cases where the cable above the suspension frame 02 breaks or a crane malfunction causes the connecting corridor to potentially fall, the support frame 01, fixed to the slide rail... When the steel cable descends along the connecting corridor, the locking wheel 11 rotates clockwise, causing the claws 24 to be locked by the limiting pins 30. This prevents the locking wheel 11 from rotating, thus locking the steel cable and preventing the connecting corridor from collapsing. Because multiple claws 24 are provided, and multiple limiting pins 30 are positioned corresponding to each claw 24, all claws 24 are simultaneously held by the limiting pins 30, increasing the locking force and ensuring even force distribution on the limiting pins 30. This prevents deformation due to unilateral force, which could lead to loss of locking function. Once the locking wheel 11 is locked and cannot rotate, the descent of the steel cable will cause the locking wheel 11 to simultaneously descend, driving the rotating frame 10 equipped with the slide rod 09. At this time, the rotating frame 10 will... The cable descends along the trajectory of the slide bar 09, thus moving to the side of the rotating frame 10 fixedly mounted on the suspension frame 02 away from the steel cable. Therefore, the steel cable is S-shaped between the two sets of rope pulleys and continuously wavy between the multiple sets of locking devices. As a result, the steel cable will be partially wrapped around the upper side of the locking wheel 11, so the steel cable can be hung on the locking wheel 11, and the locking wheel 11 can bear the weight. Since the multiple slide bars 09 are fixedly connected by the connecting plate 13, the multiple rotating frames 10 with slide bars 09 will move simultaneously, so the multiple locking wheels 11 will bear the weight simultaneously, thereby further improving the load-bearing effect. In addition, the movement of the rotating frame 10 increases the contact area between the steel cable and the locking wheel 11 due to the winding of the steel cable, thereby increasing the friction and improving the locking effect.In addition, the support frame 01 is a triangular frame, which can improve the strength of the structure, thus facilitating the suspension effect of the connecting corridor. Furthermore, during use, since the claw 24 has an inclined surface, it can be pushed into the support block 23 by the limit pin 2 30 when it rotates counterclockwise, thus not affecting the rotation of the locking wheel 11.

[0042] Because it is equipped with a claw 24, a limit pin 2 30, a rotating frame 10, and a sliding rod 09, the steel cable can be locked by the locking wheel 11 in the event of an accident. The misalignment of the two sets of rope wheels further improves the locking force and the suspension force on the steel cable, thereby ensuring the locking effect on the steel cable.

[0043] As a further aspect of the present invention, two sets of mirror-arranged braking assemblies are fixedly connected to the side of the support frame 01 away from the suspension frame 02. Each braking assembly includes multiple locking holes 04 on the slide rail 03, and a slide table 22 slidably connected within the slide rail 03. A mounting platform 17 is fixedly connected to the slide table 22, and a brake pawl 18 is slidably connected within the mounting platform 17. A wedge 19, capable of moving the brake pawl 18 outwards from the mounting platform 17, is slidably connected within the mounting platform 17. A fixed support frame 01 is also fixedly connected to... A fixed rod 21 and a sliding rod 20 are fixedly connected to the side of the wedge block 19 away from the mounting platform 17. A spring is provided between the fixed rod 21 and the wedge block 19 to reset the wedge block 19 towards the mounting platform 17. A limit pin 05 is also slidably connected to the support frame 01. The end of the sliding rod 20 away from the wedge block 19 is hooked on the limit pin 05. The support frame 01 is also provided with a triggering mechanism that can pull out the limit pin 05 to disengage the sliding rod 20 from the limit pin 05.

[0044] As a further embodiment of the present invention, the triggering mechanism includes a pull rope 06 fixedly connected to the limiting pin 05, and one end of the pull rope 06 away from the limiting pin 05 is fixedly connected to a rotating frame 10 on which a slide rod 09 is provided.

[0045] Combination Figures 1 to 6 When an accident occurs, the rotating frame 10 equipped with the sliding rod 09 slides, which simultaneously pulls the rope 06 to move the limit pin 05, thus pulling the limit pin 05 to move outward from the slide rail 03. In addition, the sliding rod 20 loses the limit of the limit pin 05. Under the action of the spring on the sliding rod 20, it pushes the wedge block 19 towards the mounting platform 17. The wedge block 19 pushes the brake pawl 18 towards the outside of the mounting platform 17, so that the brake pawl 18 moves into the locking hole 04. Thus, the slide platform 22 is limited in the locking hole 04 by the brake pawl 18, thereby locking the support frame 01. At this time, the locking mechanism will also pull the steel cable. Therefore, when an accident occurs, the connecting corridor can be locked at the position of the accident to prevent it from falling and causing a serious accident.

[0046] Because of the braking assembly, the support frame 01 can be installed on the ground. When the connecting corridor is lifted from the ground, the support frame 01 will rise simultaneously, thus maintaining a minimum distance between the support frame 01 and the connecting corridor. This ensures that the suspension frame 02 can always stabilize the connecting corridor. In the event of an accident, the movement of the rotating frame 10 can trigger the braking assembly immediately via the pull rope 06. This allows the braking assembly to work in conjunction with the locking device to lock the connecting corridor onto the slide rail 03 immediately, preventing accidents. The immediate locking also prevents the connecting corridor from falling excessively, reducing the risk of the braking assembly and locking device failing to lock properly due to the downward inertia. Because the brake pawl 18 has a downward-sloping portion, when... When the brake pawl 18 is partially engaged in the locking hole 04, the gravity of the connecting corridor will cause the slide 22 to move downwards, and the brake pawl 18 will continue to slide outwards from the mounting platform 17. As a result, the entire inclined part will be engaged in the locking hole 04, thus ensuring that the brake pawl 18 is not only partially engaged in the locking hole 04 due to the rapid descent of the connecting corridor, which could lead to problems such as the brake pawl 18 being prone to breakage or slippage. During implementation, it is also necessary to ensure that the length of the locking hole 04 is greater than the width of the brake pawl 18, so as to ensure that the brake pawl 18 has enough time to enter the locking hole 04. In addition, when the support frame 01 is fixedly installed on the slide rail 03, a pin can be inserted into the locking hole 04 to support the slide 22, thereby supporting the support frame 01.

[0047] As a further embodiment of the present invention, a pusher frame 07 is also fixedly connected to the support frame 01, and two mirror-shaped grippers 08 are slidably connected within the pusher frame 07.

[0048] Furthermore, because the connecting corridor is fan-shaped, unlike traditional connecting corridors, its center of gravity is not at the center of the diagonal of the four crane cables during lifting, but rather leans towards the convex side of the arc. Therefore, if only the four corners are lifted, the entire structure will tilt and cannot be lifted. Thus, during initial installation, the claws 08 can be manually fastened to the frame at the corners of the connecting corridor. Once all four corners are fastened with the claws 08, during the lifting process, even if the fan-shaped connecting corridor shifts due to gravity, the claws 08 can hold down one of the lowered corners. Since the support frame 01 is limited and slidably connected within the slide rail 03, the slide rail 03 can limit the support frame 01 during lifting, preventing the push frame 07 from moving and thus preventing the connecting corridor from tilting. This ensures horizontal lifting, guarantees lifting stability, and facilitates subsequent welding.

[0049] As a further embodiment of the present invention, the push frame 07 is provided with springs fixedly connected to the claws 08 at both ends. The claws 08 are fixedly connected to the latch rod 25 on the side that is close to each other. The push frame 07 is fixedly connected with a limiting pin 27, which passes through the sliding latch rod 25. The end of the limiting pin 27 away from the sleeve 28 is slidably connected to a wedge block 29. The limiting pin 27 is provided with a spring plate that can reset the wedge block 29 toward the outside of the limiting pin 27. The push frame 07 is provided with a through hole that communicates with the sleeve 28. The lower side of the push frame 07 is slidably connected to a top pin 26. The sleeve 28 is provided with a spring that can move the limiting pin 27 away from the top pin 26.

[0050] During installation, pressing the push frame 07 from top to bottom will push the top pin 26 upward, causing the top pin 26 to push the wedge block 29 into the limit pin 3 27. As a result, the limit pin 3 27 will retract into the sleeve 28 under the action of the spring, thus the limit pin 3 27 will no longer limit the two locking rods 25. As a result, the two grippers 08 will move towards each other under the action of the spring in the push frame 07, thus the two grippers 08 will fasten to both sides of the steel frame of the connecting corridor, thereby clamping the connecting corridor. This can achieve the function of adapting to different specifications of steel frames and the function of automatic clamping.

[0051] As a further embodiment of the present invention, anti-slip strips 14 are provided on the locking wheel 11 and the auxiliary wheel 12.

[0052] The anti-slip strip 14 can increase the friction between the locking wheel 11 and the auxiliary wheel 12 and the steel cable, thereby improving the locking effect on the steel cable.

[0053] As a further embodiment of the present invention, pulleys 16 are provided on both sides of the slide table 22.

[0054] Due to the offset of the fan-shaped connecting corridor, after being limited by the push frame 07, its force will be applied to the slide table 22 through the support frame 01. One side of the slide table 22 will be tightly attached to the inside of the slide rail 03. The pulley 16 can reduce the friction of the slide table 22 when it slides in the slide rail 03, thereby ensuring that the lifting effect will not be affected by the friction of the slide table 22 when lifting.

[0055] As a further aspect of the present invention, the specific steps of the construction method for the hoisting device of the fan-shaped asymmetric integrated steel structure corridor are as follows:

[0056] Step 1: Fix multiple slide rails 03 arranged in a straight line to the exterior wall of the building. Then install the support frame 01 inside the slide rails 03. Then pass the crane's steel cable from the top of the suspension frame 02 downward through the suspension frame 02. During the process, the steel cable needs to pass from top to bottom between each locking wheel 11 and auxiliary wheel 12. Finally, fix it to the connecting corridor.

[0057] Step 2: During the hoisting process, as the connecting corridor rises, when the connecting corridor moves to the position of the pusher 07, the connecting corridor will push the pusher 07 to push the support frame 01 to move upward at the same time. The support frame 01 will slide upward in the slide rail 03 through the slide table 22.

[0058] Step 3: When a crane accident occurs, the connecting corridor will pull the steel cable downwards. At this time, the pawl 24 will abut against the limit pin 30, so the locking wheel 11 cannot rotate, thus locking the steel cable and preventing it from sliding down. At the same time, the rotating frame 10 equipped with the slide rod 09 will pull the locking wheel 11 downwards after the steel cable is locked. The rotating frame 10 equipped with the slide rod 09 will slide downwards on the suspension frame 02 through the slide rod 09. The rotating frame 10 equipped with the slide rod 09 will move to the side of the rotating frame 10 fixedly connected to the suspension frame 02 away from the steel cable, forming an interlaced shape, so that part of the steel cable is wrapped around the locking wheel 11. Thus, the rotating frame 10 fixedly connected to the suspension frame 02 can hook the steel cable, thereby further locking it.

[0059] Step 4: As the rotating frame 10 with slide rod 09 slides, it will pull the pull rope 06 to move. The pull rope 06 will pull the limit pin 05 out of the slide rail 03. The slide rod 20, which is no longer limited by the limit pin 05, will move away from the limit pin 05 under the action of the spring. This will push the wedge block 19 into the mounting platform 17. The wedge block 19 will push the brake pawl 18 towards the locking hole 04. The brake pawl 18 can then be locked in the locking hole 04. Thus, the slide table 22 is braked by the brake pawl 18, preventing it from continuing to slide on the slide rail 03.

8. A construction method for a fan-shaped asymmetric integrated steel structure corridor hoisting device, applicable to the fan-shaped asymmetric integrated steel structure corridor hoisting device as described in claim 5, characterized in that: The specific steps for constructing the hoisting device for the fan-shaped asymmetric integrated steel structure corridor are as follows: Step 1: Fix multiple slide rails (03) arranged in a straight line to the outer wall of the building. Then install the support frame (01) inside the slide rail (03). Then pass the steel cable of the crane down through the suspension frame (02) from the top side. During the process, the steel cable needs to pass through each locking wheel (11) and auxiliary wheel (12) from top to bottom. Finally, fix it to the connecting corridor. Step 2: During the hoisting process, as the connecting corridor rises, when the connecting corridor moves to the position of the pusher (07), the connecting corridor will push the pusher (07) to push the support frame (01) to move upward at the same time. The support frame (01) will slide upward in the slide rail (03) through the slide table (22); Step 3: When a crane accident occurs, the connecting corridor will pull the steel cable downward. At this time, the pawl (24) will abut against the limit pin 2 (30), so the locking wheel (11) cannot rotate, thus locking the steel cable and preventing it from sliding down. At the same time, the rotating frame (10) equipped with the slide bar (09) will pull the locking wheel (11) downward after the steel cable is locked. Thus, the rotating frame (10) equipped with the slide bar (09) will slide downward on the suspension frame (02) through the slide bar (09). Thus, the rotating frame (10) equipped with the slide bar (09) will move to the side of the rotating frame (10) fixedly connected to the suspension frame (02) away from the steel cable, forming an interlocking structure, so that part of the steel cable is wrapped around the locking wheel (11), thus enabling the rotating frame (10) fixedly connected to the suspension frame (02) to hook the steel cable, thereby further locking it. Step 4: While the rotating frame (10) with the sliding rod (09) is sliding, the pull rope (06) will be pulled. The pull rope (06) will pull the limit pin (05) out from the slide rail (03). The sliding rod (20) without the limit pin (05) will move away from the limit pin (05) under the action of the spring. This will push the wedge block (19) towards the mounting platform (17). The wedge block (19) will push the brake pawl (18) towards the locking hole (04). The brake pawl (18) can be locked in the locking hole (04). Thus, the slide table (22) is braked by the brake pawl (18), so that it cannot continue to slide on the slide rail (03).
