Description

Technical Field

[0001] The present invention relates to the technical field of safety rope brackets, and more specifically, to a steel structure safety rope fixing bracket. Background Art

[0002] In modern construction, bridge and other engineering fields, steel structures are widely used due to their high strength, good toughness, convenient construction and other advantages. During the construction and subsequent maintenance of steel structures, construction workers need to work on high-altitude or suspended steel structure components. To ensure the safety of construction workers, the safety rope fixing bracket has become an indispensable and important device. It can provide a reliable fixing point for the safety rope to ensure that construction workers will not fall in case of an accident.

[0003] The utility model patent with the publication number CN205663232U specifically discloses a steel structure horizontal safety rope fixing bracket, which includes a steel pipe. The steel pipe is provided with through holes for passing through steel wires. One end of the steel pipe is fixed on a bracket. The bracket includes a U-shaped channel steel that can be inserted into the flange of a high-rise steel beam. The steel pipe is fixed on the steel plate on one side of the U-shaped notch of the channel steel. There is a pressing plate in the U-shaped notch of the channel steel. Bolts passing through the steel plate of the channel steel on one side of the U-shaped notch are fixed on the pressing plate. Nuts are respectively arranged on the bolts on both sides of the channel steel plate. An insurance hook is also arranged on the bracket. The insurance hook is used to prevent the notch of the channel steel from falling off the inserted flange of the high-rise steel beam. By rotating the nut on the bolt inside the notch, the pressing plate is pushed forward to clamp the flange of the high-rise steel beam together with the channel steel plate on the other side of the notch, thereby fixing the safety rope bracket on the I-beam. However, in actual situations, one side of the channel steel plate is exposed on the surface of the upper flange of the I-beam, and the insurance hook spans the width direction of the I-beam and is erected above the upper flange. Such a design results in the occupation of the effective walking space on the surface of the upper flange of the I-beam. When construction workers walk on the flange, they are extremely likely to be tripped by the protruding steel plate edge or the insurance hook, posing a safety hazard of high-altitude falling caused by tripping.

[0004] In summary, the deficiencies of the existing safety rope fixing brackets are as follows: the fixing structure of the safety rope fixing bracket occupies the space on the surface of the upper flange of the I-beam, and the components protrude from the walking plane, affecting the passage of construction workers on the I-beam. Summary of the Invention

[0005] In view of the deficiencies of the existing technology, the present invention proposes a safety rope fixing bracket that clamps the upper end surface of the lower flange of the I-beam and the lower end surface of the upper flange, so as to solve the problem that the fixing structure of the safety rope fixing bracket occupies the space on the surface of the upper flange of the I-beam and affects the passage of construction workers on the I-beam.

[0017] Preferably, an annular limiting groove with an axis coinciding with the axis of the guiding hole is formed in the first horizontal plate on the side away from the outer orifice of the guiding hole. The annular limiting groove communicates with the guiding hole, and the groove width of the annular limiting groove is greater than the inner diameter of the guiding hole. A guiding column limiting block is fixed at the end of the guiding column away from the horizontal plate. The annular limiting groove restricts the guiding column limiting block in the groove and enables the guiding column limiting block to slide only along the axial direction of the annular limiting groove.

[0018] Preferably, a vertical hole is formed in the vertical plate, the axial direction of which is consistent with the axial direction of the vertical plate, and a horizontal hole is formed in the horizontal plate, the axial direction of which is consistent with the axial direction of the horizontal plate.

[0020] Preferably, the steel structure safety rope fixing bracket further includes a plurality of rubber pads; the plurality of rubber pads are respectively fixedly installed on the lower end surface of the first clamping block and the upper end surface of the second clamping block.

[0021] Preferably, a plurality of hanging rings for threading the safety rope are fixedly installed on the fixed column.

[0022] Compared with the prior art, the steel structure safety rope fixing bracket of the present invention has at least the following beneficial effects:

[0023] 1. In this application, by setting the second cross plate, the first clamping block and the second clamping block, the first clamping block slides and abuts against the upper end surface of the lower flange of the I-beam, the second clamping block slides and abuts against the end surface of the upper flange of the I-beam, the second cross plate is located outside the I-beam, and the fixed column is fixedly installed on the second cross plate, so that the safety rope fixing bracket can clamp I-beams of different specifications without occupying the surface space of the upper flange of the I-beam, reducing the risk of workers tripping on the I-beam.

[0024] 2. In this application, by setting the L-shaped clamping block, the second screw rod and the second threaded hole, the L-shaped clamping block is driven to move by rotating the second screw rod. The vertical plate and the vertical plate of the L-shaped clamping block jointly clamp the left and right side walls of the lower flange of the I-beam, increasing the clamping of the safety rope fixing bracket in the width direction of I-beams of different specifications, and further increasing the ability of the safety rope fixing bracket to resist the impact force in the length direction of the I-beam.

[0025] 3. In this application, by providing a first bevel gear, a second bevel gear and a first rotating rod, when the second screw rotates, it can drive the L-shaped clamping block to move. However, due to the unfavorable position of the second screw for direct operation by workers, through the meshing transmission design of the first bevel gear and the second bevel gear, the operator only needs to rotate the first rotating rod, and the second screw can be indirectly driven to rotate by means of gear transmission, thus converting the originally inconvenient horizontal rotation of the second screw into rotating the rotating rod in the vertical direction, improving the convenience and safety of on-site operations.

[0038] The following individual embodiments are only for illustration. Combinations can be made between the individual embodiments, and it is not limited to the content shown in the following single embodiment.

[0039] In this embodiment, refer to Figures 2 - 5 , the present invention provides a steel structure safety rope fixing bracket, belonging to the field of safety rope brackets, and is used to solve the problem that the fixing structure of the safety rope fixing bracket occupies the surface space of the upper flange of the I-beam and affects the passage of construction workers on the I-beam.

[0040] The steel structure safety rope fixing bracket mainly includes a Z-shaped mounting block 1, a through groove 2, a first clamping block 3, a second clamping block 4, and a fixed column 5.

[0041] More specifically, the Z-shaped mounting block 1 includes a first horizontal plate 101 at the bottom, a vertical plate 102 in the middle, and a second horizontal plate 103 at the top. The first horizontal plate 101 and the second horizontal plate 103 are respectively arranged on the left and right sides of the vertical plate 102. The first horizontal plate 101 is located below the lower flange of the I-beam, and the side wall of the vertical plate in the same direction as the first horizontal plate 101 is in contact with the side walls of the upper and lower flanges on the same side of the I-beam. The second horizontal plate 103 is located outside the I-beam;

[0042] A through groove 2 penetrating the left and right side walls of the vertical plate is opened at the middle position of the vertical plate 102;

[0043] The first clamping block 3 is slidably installed in the through groove 2, and the sliding direction of the first clamping block 3 is parallel to the height direction of the vertical plate 102. The lower end surface of the first clamping block 3 can be adjusted to abut against the upper end surface of the lower flange of the I-beam;

[0044] The second clamping block 4 is slidably installed in the through groove 2 and is located above the first clamping block 3. The sliding direction of the second clamping block 4 is the same as that of the first clamping block 3. The upper end surface of the second clamping block 4 can be adjusted to abut against the lower end surface of the upper flange of the I-beam;

[0045] Here, a clamping block guiding protrusion is correspondingly arranged on each of the front and rear side walls of the through groove 2. The upper end of the clamping block guiding protrusion is connected to the upper wall of the through groove 2, and the lower end is connected to the lower wall of the through groove 2. At the same time, first clamping block guiding grooves are opened on the front and rear outer side walls of the first clamping block 3. The first clamping block guiding grooves cooperate with the corresponding clamping block guiding protrusions on the same side to slidably install the first clamping block 3 in the through groove 2. Similarly, second clamping block guiding grooves are opened on the front and rear outer side walls of the second clamping block 4. The second clamping block guiding grooves cooperate with the corresponding clamping block guiding protrusions on the same side to slidably install the second clamping block 4 in the through groove 2, and at the same time, the second clamping block 4 slides above the first clamping block 3;

[0046] The fixing column 5 is fixedly installed on the upper part of the second horizontal plate 103, and the safety rope is fixed to the fixing column 5.

[0047] Here, the fixed installation form of the fixing column 5 and the second horizontal plate 103 is not limited. It can be welding or integrally formed;

[0048] Through this setting, the first clamping block 3 and the second clamping block 4 are located between the lower flange and the upper flange of the I-beam, and clamp the upper end surface of the lower flange and the lower end surface of the upper flange of the I-beam. This form of clamping the I-beam will reduce the space occupied by the safety rope fixing bracket on the upper surface of the I-beam, thereby reducing the risk that workers are easily tripped when walking on the I-beam.

[0049] In this embodiment, refer to Figures 2 - 5, the steel structure safety rope fixing bracket further includes a first threaded rod. A first through hole 7 is formed in the upper end surface of the vertical plate 102 along the height direction of the vertical plate, and the first through hole 7 communicates with the through groove 2; a first threaded hole is formed through the second clamping block 4, and the axis of the first threaded hole is parallel to the sliding direction of the second clamping block; the lower end of the first threaded rod sequentially passes through the first through hole 7 and the first threaded hole and is rotatably connected to the lower first clamping block 3;

[0050] Here, in this embodiment, the lower end of the first screw 6 is rotatably connected to the first clamping block 3 through a bearing. Specifically, a first bearing is fixedly installed on the first clamping block 3, and the lower end of the first screw 6 is fixedly connected to the inner ring of the first bearing by welding;

[0051] The first threaded rod is threadedly connected to the first threaded hole, and the upper end of the first threaded rod is located outside the vertical plate 102;

[0052] Here, in this embodiment, pulling the first screw 6 upward along the axis direction of the first through hole drives the first clamping block 3 to slide. Then, the first clamping block 3 can be first placed on the lower flange of the I-beam, and the lower end surface of the first clamping block 3 abuts against the upper end surface of the lower flange of the I-beam; subsequently, rotating the first screw 6 clockwise, the first screw 6 drives the second clamping block 4 to slide upward along the guiding direction of the clamping block guiding protrusion through the thread. At this time, the pressing force between the upper end surface of the second clamping block 4 and the lower end surface of the upper flange of the I-beam increases, and at the same time, the pressing force between the lower end surface of the first clamping block 3 and the upper end surface of the lower flange also increases, thereby realizing the clamping of the I-beam by the first clamping block 3 and the second clamping block 4;

[0053] When the screw is rotated counterclockwise, the second clamping block 4 slides downward. At this time, the distance between the first clamping block 3 and the second clamping block 4 is less than the distance between the upper flange and the lower flange of the I-beam, so as to cancel the clamping of the I-beam by the first clamping block 3 and the second clamping block 4;

[0054] Through this setting, in this embodiment, by rotating the first screw 6 to adjust the distance between the first clamping block 3 and the second clamping block 4, this form can adapt to I-beams of different specifications, increasing the applicability of the safety rope fixing bracket to I-beams of different specifications.

[0055] In this embodiment, refer to Figure 2 , Figure 4 and Figure 5, the steel structure safety rope fixing bracket further includes a limiting tube 9. A second through hole 10 is formed in the upper end surface of the second transverse plate 103 along the sliding direction of the clamping block. The fixing column 5 is of a hollow structure and is located directly above the second through hole 10. The lower end of the limiting tube 9 is fixedly installed on the upper surface of the first clamping block 3. The upper end of the limiting tube 9 correspondingly slides upward and extends out of the second through hole 10 and extends into the fixing column 5; a plurality of locking holes 13 are formed in the outer wall of the limiting tube 9 on the side away from the I-shaped beam along the axis direction of the limiting tube, and the axis of the locking hole 13 is perpendicular to the axis of the second through hole 10; a locking channel 14 parallel to the axis direction of the locking hole is formed in the outer wall of the second transverse plate 103 on the side away from the vertical plate 102, and the locking channel 14 communicates with the second through hole 10; the rod end of a locking rod 12 slides into the locking channel 14 from the outside to the inside and can extend into the corresponding locking hole 13. A locking rod limiting block 15 is installed at one end of the locking rod 12 outside the locking channel 14. A spring 11 is sleeved on the locking rod 12, and one end of the spring 11 is fixedly connected to the outer wall of the second transverse plate 103 on the side away from the vertical plate 102, and the other end is fixedly connected to the locking rod limiting block 15.

[0056] In this embodiment, the fixing column 5 is of a hollow structure and is located directly above the second through hole 10. When the first clamping block 3 is placed on the lower flange of the I-shaped beam, the limiting tube 9 follows the first clamping block 3 through the second through hole 10 and slides into the fixing column 5. When the axis of the locking hole 13 on the limiting tube 9 coincides with the axis of the locking channel 14, at this time the locking channel 14 communicates with the inside of the limiting tube 9. Then, the locking rod 12 is slid and inserted along the axis direction of the locking channel 14. One end of the locking rod 12 is inserted into the locking hole 13 to prevent the sliding of the limiting tube 9, thereby preventing the relative displacement between the first clamping block 3 and the Z-shaped mounting block 1.

[0057] Meanwhile, in this embodiment, there is no limitation on the fixed installation method of the locking rod limiting block 15, which can be welding or integral.

[0058] The initial position of the locking rod 12 under the action of the spring 11 is that one end extends into the second through hole 10 along the locking channel 14. By pulling the locking rod limiting block 15, the locking rod 12 is completely pulled out of the second through hole 10. At this time, the limiting tube 9 can freely slide into the second through hole 10. When the axes of the locking hole 13 and the locking channel 14 coincide, the locking rod limiting block 15 is released. At this time, the spring 11 will make the locking rod 12 reset and insert into the corresponding locking hole 13 due to the elastic force of elastic deformation, forming a mechanical lock;

[0059] With this setting in this embodiment, the spring 11 ensures that the locking rod 12 is always connected to the locking channel 14, avoiding the risk of accidental dropping of the locking rod 12 during high-altitude operations, and the locking state of the limiting tube 9 is maintained by the force of the spring 11, without the need for additional tools for fastening, reducing the operation difficulty of workers.

[0060] In this embodiment, referring to Figure 2 , Figure 3 and Figure 4 , the steel structure safety rope fixing bracket further includes an L-shaped clamping block 16 and a second screw 17. The L-shaped clamping block 16 further includes a vertical plate on the upper side and a horizontal plate on the lower side. The L-shaped clamping block 16 and the Z-shaped mounting block 1 are respectively arranged on the left and right sides in the width direction of the I-beam, and the L-shaped clamping block 16 can move left and right in the width direction of the I-beam. The vertical plates arranged on the left and right sides and the vertical plate 102 form a clamping space capable of clamping the left and right side walls of the lower flange of the I-beam; a second threaded hole 18 is opened on the side wall of the first horizontal plate 101 close to the L-shaped clamping block, and the axis of the second threaded hole 18 is parallel to the moving direction of the L-shaped clamping block 16; one end of the second screw 17 is rotatably connected to the horizontal plate, and the other end extends into the second threaded hole 18 and is threadedly connected to the second threaded hole 18.

[0061] Here, in this embodiment, the second screw 17 is rotatably connected to the L-shaped clamping block 16 through a bearing. A second bearing is fixedly installed on the side wall of the horizontal plate of the L-shaped clamping block 16 close to the first horizontal plate, and the corresponding end of the second screw 17 is fixedly connected to the inner ring of the second bearing by welding;

[0062] Here, in this embodiment, when the second screw 17 is rotated clockwise, the second screw 17 makes the L-shaped clamping block 16 move in the direction close to the first horizontal plate 101 along the axis direction guiding the second screw 17 through the thread. At this time, the side walls of the vertical plates of the L-shaped clamping block 16 and the side walls of the vertical plates of the Z-shaped mounting block 1 jointly clamp the left and right side walls of the lower flange of the I-beam; similarly, when the second screw 17 is rotated counterclockwise, the L-shaped clamping block 16 moves in the direction away from the first horizontal plate 101;

[0063] Through this setting, this embodiment increases the clamping of the safety rope fixing bracket in the width direction of I-beams with different specifications, and further increases the ability of the safety rope fixing bracket to withstand the impact force in the length direction of the I-beam.

[0064] In this embodiment, referring to Figure 3 and Figure 4 , a guiding hole 20 is further opened on the side wall of the first horizontal plate 101 of the steel structure safety rope fixing bracket close to the L-shaped clamping block 16, and the axis of the guiding hole 20 is parallel to the moving direction of the L-shaped clamping block 16; a guiding column 19 is connected to the side wall of the horizontal plate close to the first horizontal plate, and the end of the guiding column 19 away from the horizontal plate is slidably and fittingly inserted into the corresponding guiding hole 20.

[0065] Here, in this embodiment, the number of the guiding columns 19 and the guiding holes 20 is two each. The two guiding holes 20 are respectively arranged on both sides of the second threaded hole 18, and the two guiding holes 20 correspond to the two guiding columns 19 one by one;

[0066] With this setting, rotation of the L-shaped clamping block 16 is avoided when the second screw 17 rotates, enabling the L-shaped clamping block 16 to slide only along the axial direction of the guide post 19, thereby enhancing the stability of the safety rope fixing bracket.

[0067] In this embodiment, referring to Figure 3 and Figure 5 , in the first cross plate 101 on the side of the guide hole 20 away from its outer hole opening in the steel structure safety rope fixing bracket, an annular limiting groove 22 with an axis coinciding with the axis of the guide hole is formed. The annular limiting groove 22 communicates with the guide hole 20, and the groove width of the annular limiting groove 22 is greater than the inner diameter of the guide hole 20. A guide post limiting block 21 is fixed to the end of the guide post 19 away from the horizontal plate. The annular limiting groove 22 confines the guide post limiting block 21 within the groove and enables the guide post limiting block 21 to slide only along the axial direction of the annular limiting groove 22.

[0068] Here, the length of the annular limiting groove 22 is less than the length of the guide hole 20, and the part where the annular limiting groove 22 communicates with the guide hole 20 forms a limiting channel. The guide post limiting block 21 slides within the limiting channel. With this setting, when the second screw 17 is rotated to move the L-shaped clamping block 16 towards the side away from the first cross plate 101, the guide post limiting block 21 prevents the guide post 19 from detaching from the first cross plate 101, thereby avoiding the risk of the L-shaped clamping block 16 disconnecting from the first cross plate 101.

[0069] In this embodiment, referring to Figure 4 , Figure 6 and Figure 7 , in the steel structure safety rope fixing bracket, a vertical plate inner hole with an axial direction consistent with the axial direction of the vertical plate is formed in the vertical plate, a horizontal plate inner hole with an axial direction consistent with the axial direction of the horizontal plate is formed in the horizontal plate, and a transmission cavity 23 is formed at the intersection of the vertical plate inner hole and the horizontal plate inner hole inside the L-shaped clamping block 16; a first rotating rod 26 is adaptively inserted into the vertical plate inner hole and rotatably connected to the vertical plate. At the same time, the lower end of the first rotating rod 26 extends into the transmission cavity 23, and the upper end is located outside the vertical plate;

[0070] Here, in this embodiment, the first rotating rod 26 is rotatably connected to the vertical plate of the L-shaped clamping block 16 through a bearing. A third bearing is fixedly installed on the upper end face of the vertical plate, and the outer wall of the first rotating rod 26 is fixedly connected to the inner ring of the third bearing by welding;

[0071] One end of the second screw 17 rotatably connected to the horizontal plate extends into the transmission cavity 23 along the horizontal plate inner hole; a first bevel gear 24 is fixedly installed at one end of the first rotating rod 26 located in the transmission cavity 23, a second bevel gear 25 is installed at one end of the second screw 17 located in the transmission cavity 23, and the first bevel gear 24 is meshed with the second bevel gear 25 in a matching manner.

[0072] Here, in this embodiment, when the first rotating rod 26 is rotated clockwise, the first bevel gear 24 rotates clockwise following the first rotating rod 26. Since the axes of the second bevel gear 25 and the first bevel gear 24 are perpendicular to each other, and the second bevel gear 25 is located on the right side of the first bevel gear 24, the first bevel gear 24 drives the second bevel gear 25 to rotate clockwise, thereby driving the second screw rod 17 to rotate clockwise. The L-shaped clamping block 16 moves towards the direction close to the first cross plate 101 through the second screw rod 17 rotating clockwise; when the first rotating rod 26 is rotated counterclockwise, the L-shaped clamping block 16 similarly moves away from the first cross plate 101 through the second screw rod 17 rotating counterclockwise.

[0073] Through this setting, the operator only needs to rotate the first rotating rod 26, and can indirectly drive the second screw rod 17 to rotate by means of gear transmission, thereby converting the originally inconvenient way of horizontally rotating the second screw rod into rotating the first rotating rod in the vertical direction, improving the convenience and safety of on-site operations.

[0074] In this embodiment, referring to Figure 3 、 Figure 4 and Figure 7 , the first rotating rod 26 in the steel structure safety rope fixing bracket is a hollow rod with an open upper side and a sealed lower side. The lower end of a second rotating rod 27 extends into the first rotating rod 26, and the upper end extends out of the first rotating rod 26; a guiding protrusion 29 is fixedly installed at the lower end of the second rotating rod 27, and a guiding groove 28 is formed in the middle of the inner wall of the first rotating rod 26. The guiding groove 28 is slidably connected with the guiding protrusion 29 in a matching manner, and the sliding direction of the guiding protrusion 29 is parallel to the rotation axis direction of the first rotating rod 26.

[0075] Here, a guiding groove 28 is formed in the middle of the inner wall of the first rotating rod 26. The guiding protrusion 29 contacts the upper wall of the guiding groove 28 and prevents the second rotating rod 27 from sliding out of the first rotating rod 26. The cooperation between the guiding protrusion 29 and the guiding groove 28 enables the first rotating rod 26 to rotate following the second rotating rod 27.

[0076] Here, as Figure 3 , a semi-circular handwheel is also fixedly installed on the second rotating rod 27. When the second rotating rod 27 is pulled upward to be higher than the upper surface of the I-beam, the semi-circular handwheel can avoid interference with the upper flange of the I-beam.

[0077] Through this setting, in the non-working state, the worker can place the handwheel below the upper surface of the I-beam, avoiding the handwheel being higher than the upper surface of the I-beam, which may cause problems such as tripping the worker's walking and accidental operation due to accidental collision. When the first rotating rod 26 needs to be rotated, the handwheel can be pulled upward to drive the second rotating rod 27 to slide upward to raise the operation plane of the handwheel, thereby facilitating the safe operation of the worker.

[0078] In this embodiment, referring to Figure 3 , the steel structure safety rope fixing bracket further includes a plurality of rubber pads 30; the plurality of rubber pads 30 are respectively fixedly installed on the lower end surface of the first clamping block 3 and the upper end surface of the second clamping block 4.

[0079] Here, the material of the rubber pad 30 is not limited, it can be neoprene, or it can be nitrile rubber;

[0080] In this embodiment, by arranging the rubber pads 30 on the first clamping block 3 and the second clamping block 4, the friction between the first clamping block 3 and the second clamping block 4 and the I-beam can be increased, and the scratching of the I-beam can also be reduced.

[0081] In this embodiment, referring to Figure 1 and Figure 2 , a plurality of hanging rings 8 for threading a safety rope are fixedly installed on the fixing column 5 in the steel structure safety rope fixing bracket.

[0082] Here, the fixed installation form of the hanging ring 8 is not limited, it can be welding, or it can be connected by threads.

[0083] The specific usage method of this embodiment is as follows:

[0084] During installation, the worker first fits the vertical plate 102 to the side of the lower flange of the I-beam, and places the first horizontal plate 101 below the lower flange and presses it tightly against the lower end surface of the lower flange. At this time, pull the lock rod limit block 15 outwards and place the first clamping block 3 on the upper end surface of the lower flange. After the limit tube 9 slides and penetrates into the second through hole 10 and the locking hole 13 is aligned with the locking channel 14, release the lock rod limit block 15. At this time, the lock rod 12 is reset and inserted into the locking hole 13 through the spring 11, and then rotate the first screw rod 6 clockwise to make the first clamping block 3 press tightly against the upper end surface of the lower flange, and at the same time make the second clamping block 4 press tightly against the lower end surface of the upper flange to complete the clamping in the vertical direction;

[0085] Subsequently, the worker pulls the handwheel upwards to raise the handwheel, drives the second rotating rod 27 to rotate clockwise by rotating the handwheel, the second rotating rod 27 drives the first rotating rod 26 to rotate, and the first rotating rod 26 drives the second screw rod 17 to rotate clockwise through the meshing of the first bevel gear 24 and the second bevel gear 25. The second screw rod 17 rotates clockwise to drive the L-shaped clamping block 16 to move towards the direction of the first horizontal plate, so that the side wall of the vertical plate of the L-shaped clamping block 16 clamps the left and right side walls of the lower flange of the I-beam to achieve the fixation in the horizontal direction;

[0086] The worker then connects the safety rope to the hanging ring 8 on the fixing column 5 and presses down the handwheel to hide it below the surface of the upper flange to ensure that there are no protruding parts affecting the passage;

[0087] When disassembling, first pull and rotate the handwheel counterclockwise to release the clamping force of the safety rope fixing bracket on the I-beam in the horizontal direction, and then rotate the first screw 6 counterclockwise to release the clamping force of the safety rope fixing bracket on the I-beam in the vertical direction.
