Description

Technical Field

[0001] This utility model belongs to the field of safety rope supports, and in particular relates to a steel structure safety rope fixing support. Background Technology

[0002] In modern construction, bridge engineering, and other fields, steel structures are widely used due to their advantages such as high strength, good toughness, and convenient construction. During the construction and subsequent maintenance of steel structures, workers need to operate on steel structural components at heights or in mid-air. To ensure the safety of these workers, safety rope fixing supports are an indispensable and crucial device. They provide reliable anchor points for safety ropes, ensuring that workers will not fall in the event of an accident.

[0003] The invention disclosed in CN205663232U specifically discloses a horizontal safety rope fixing bracket for steel structures, including a steel pipe with through holes for steel wires to pass through. One end of the steel pipe is fixed to a bracket, which includes a U-shaped channel steel that can be inserted into the flange of an elevated steel beam. The steel pipe is fixed to a steel plate on one side of the U-shaped groove of the channel steel. A pressure plate is located in the U-shaped groove of the channel steel, and bolts passing through the channel steel plate on one side of the U-shaped groove are fixed on the pressure plate. Nuts are respectively provided on the bolts on both sides of the channel steel plate. The bracket is also equipped with a safety hook to prevent the groove of the channel steel from falling off the flange of the elevated steel beam. By rotating the nut on the bolt inside the groove, the pressure plate is pushed forward and clamps the flange of the elevated steel beam together with the channel steel plate on the other side of the groove, thereby fixing the safety rope bracket to the I-beam. However, in actual practice, one side of the channel steel plate is exposed on the surface of the upper flange of the I-beam, and the safety hook spans the width of the I-beam and is erected above the upper flange. This type of 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 very likely to trip over the protruding steel plate edge or safety hook, which poses a safety hazard of falling from a height due to tripping.

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

[0049] As described above, the steel structure safety rope fixing bracket of this utility model has at least the following beneficial effects:

[0050] 1. This application sets up a second horizontal plate, a first clamping block and a second clamping block. The first clamping block slides and abuts against the upper end surface of the lower flange of the I-beam, and the second clamping block slides and abuts against the shaped end surface of the upper flange of the I-beam. The second horizontal plate is located on the outside of the I-beam, and the fixing column is fixedly installed on the second horizontal plate. This allows the safety rope fixing bracket to 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.

[0051] 2. This application sets up an L-shaped clamping block, a second screw, and a second threaded hole. By rotating the second screw, the L-shaped clamping block is moved. The vertical end of the L-shaped clamping block and the vertical plate work together to clamp the left and right side walls of the lower flange of the I-beam, which increases the clamping capacity of the safety rope fixing bracket for I-beams of different specifications in the width direction, thereby increasing the ability of the safety rope fixing bracket to resist the impact force in the length direction of the I-beam.

[0052] 3. This application sets up 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, since the position of the second screw is not conducive to direct operation by the worker, the meshing transmission design of the first bevel gear and the second bevel gear allows the operator to indirectly drive the second screw to rotate by rotating the first rotating rod. This transforms the originally inconvenient method of horizontally rotating the second screw into rotating the vertical rotating rod, improving the convenience and safety of on-site operations.

[0064] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0065] In this embodiment, please refer to Figure 2-5 This utility model provides a steel structure safety rope fixing bracket, which includes:

[0066] Z-shaped mounting block 1, the Z-shaped mounting block 1 includes a first horizontal plate 101, a vertical plate 102 and a second horizontal plate 103; the first horizontal plate 101 and the second horizontal plate 103 are respectively disposed on both sides of the vertical plate 102, the first horizontal plate 101 is located below the second horizontal plate 103, the first horizontal plate 101 is located below the lower flange of the I-beam, the side wall of the vertical plate 102 is in contact with the side wall of the upper flange and the lower flange on the same side of the I-beam, and the second horizontal plate 103 is located on the outside of the I-beam;

[0067] Through groove 2: A through groove 2 is provided in the middle of the vertical plate 102, penetrating the left and right side walls of the vertical plate 102;

[0068] The first clamping block 3 is slidably installed in the through groove 2. The sliding direction of the first clamping block 3 is parallel to the height direction of the I-beam. The lower end face of the first clamping block 3 abuts against the upper end face of the lower flange of the I-beam.

[0069] The second clamping block 4 is slidably installed in the through groove 2. The sliding direction of the second clamping block 4 is parallel to the sliding direction of the first clamping block 3. The upper end surface of the second clamping block 4 abuts against the lower end surface of the upper flange of the I-beam.

[0070] Here, a clamping block guide protrusion is provided on the side wall of the through groove 2. One end of the clamping block guide protrusion is connected to the upper wall of the through groove 2, and the other end of the clamping guide protrusion is connected to the lower wall of the through groove 2. A first clamping block guide groove is provided through the first clamping block 3. One side wall of the first clamping block guide groove is connected to the side wall of the first clamping block 3. The first clamping block guide groove and the clamping block guide protrusion cooperate to allow the first clamping block 3 to slide in the through groove 2. A second clamping block guide groove is provided through the second clamping block 4. One side wall of the second clamping block guide groove is connected to the side wall of the second clamping block 4. The second clamping block guide groove and the clamping block guide protrusion cooperate to allow the second clamping block 4 to slide in the through groove 2. The second clamping block 4 slides above the first clamping block 3.

[0071] Fixed post 5, the fixed post 5 is used to fix the safety rope, and the fixed post 5 is fixedly installed on the second horizontal plate 103;

[0072] Here, the form of fixing column 5 is not limited; it can be welded or integrally formed.

[0073] With this setup, the first clamping block 3 and the second clamping block 4 are positioned between the upper and lower flanges of the I-beam to clamp the I-beam, which reduces the space occupied by the safety rope fixing bracket on the upper surface of the I-beam, thereby reducing the risk of workers tripping when walking on the I-beam.

[0074] In this embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The safety rope fixing bracket is characterized in that it further includes a first screw 6, a first threaded hole and a first through hole 7;

[0075] The upper end face of the vertical plate 102 is provided with a first through hole 7 along the sliding direction of the first clamping block 3, and the first through hole 7 is connected to the through groove 2.

[0076] The second clamping plate has a through-hole with a first threaded hole, and the axis of the first threaded hole is parallel to the sliding direction of the second clamping block 4.

[0077] One end of the first screw 6 is rotatably connected to the first clamping block 3;

[0078] In this embodiment, the first screw 6 and the first clamping block 3 are rotatably connected by a bearing. The first bearing is fixedly installed on the first clamping block 3, and one end of the first screw 6 is fixedly connected to the inner ring of the first bearing by welding.

[0079] The other end of the first screw 6 passes through the first threaded hole and the first through hole 7 in sequence and extends out of the vertical plate 102. The first screw 6 is threadedly connected to the first threaded hole.

[0080] Here, the second clamping block 4 is located above the first clamping block 3. When the first screw 6 is rotated, since the first screw 6 is threadedly connected to the first threaded hole, and the first clamping block 3 is connected to the bearing of the first screw 6, the first clamping block 3 only slides linearly with the clamping block guide protrusion and does not rotate with the screw. The second clamping block 4 will slide along the extension direction of the clamping block guide protrusion.

[0081] In this embodiment, the first screw 6 is pulled upward along the axial direction of the first through hole 7 to drive the first clamping block 3 to slide, thereby placing the first clamping block 3 on the lower flange of the I-beam. When the first clamping block 3 is placed on the lower flange of the I-beam, rotating the first screw 6 clockwise causes the second clamping block 4 to slide upward along the guide direction of the clamping block guide protrusion through the screw thread. At this time, the clamping force between the upper end face of the second clamping block 4 and the lower end face of the upper flange of the I-beam increases, and the clamping force between the lower end face of the first clamping block 3 and the upper end face of the lower flange also increases. 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 of the I-beam and the lower flange of the I-beam, thereby canceling the clamping of the I-beam by the first clamping block 3 and the second clamping block 4.

[0082] With this setup, the distance between the first clamping block 3 and the second clamping block 4 can be adjusted by rotating the first screw 6. This design can accommodate I-beams of different specifications, increasing the applicability of the safety rope fixing bracket to I-beams of different specifications.

[0083] In this embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The safety rope fixing bracket is characterized in that it further includes a limiting tube 9, a second through hole 10, a spring 11, a locking rod 12, a locking hole 13, a locking channel 14, and a locking rod limiting block 15.

[0084] A second through hole 10 is provided on the upper end surface of the second horizontal plate 103, and the axis of the second through hole 10 is parallel to the sliding direction of the first clamping block 3;

[0085] One end of the limiting tube 9 is fixedly installed on the upper end face of the first clamping block 3, and the other end of the limiting tube 9 slides out of the second through hole 10.

[0086] A plurality of locking holes 13 are provided on the outer wall of the limiting tube 9 along the axial direction of the limiting tube 9, and the axis of the locking holes 13 is perpendicular to the axis of the second through hole 10.

[0087] A locking channel 14 parallel to the axis of the locking hole 13 is provided on the side wall of the second horizontal plate 103, and the locking channel 14 is connected to the second through hole 10.

[0088] The locking rod 12 is slidably installed inside the locking channel 14. One end of the locking rod 12 slides along the locking channel 14 and extends into the locking hole 13 to prevent the locking rod 12 from moving. The other end of the locking rod 12 is located outside the second horizontal plate 103.

[0089] In this embodiment, the fixing post 5 is 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-beam, the limiting tube 9 follows the first clamping block 3 through the second through hole 10 and slides into the interior of the fixing post 5. When the locking hole 13 on the limiting tube 9 coincides with the axis of the locking channel 14, the locking channel 14 connects to the interior of the limiting tube 9. At this time, the locking rod 12 is slidably inserted along the axis of the locking channel 14. One end of the locking rod 12 is inserted into the locking hole 13 to prevent the limiting tube 9 from sliding, thereby preventing the relative displacement between the first clamping block 3 and the Z-shaped mounting block 1.

[0090] The locking rod limiting block 15 is fixedly installed at one end of the locking rod 12 that extends out of the second horizontal plate 103;

[0091] The spring 11 is sleeved on the locking rod 12. One end of the spring 11 is fixedly connected to the side wall of the second horizontal plate 103, and the other end of the spring 11 is fixedly connected to the locking rod limiting block 15.

[0092] Here, there is no limitation on the fixing and installation method of the locking bar limit block 15; it can be welded or integrated.

[0093] Here, 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 slide freely into the second through hole 10. When the axis of the locking hole 13 and the locking channel 14 coincides, the locking rod limiting block 15 is released. After releasing, the spring 11 will cause the locking rod 12 to reset due to the elastic deformation and insert into the locking hole 13, forming a mechanical lock.

[0094] With this setup, the spring 11 ensures that the locking rod 12 is always connected to the locking channel 14, avoiding the risk of the locking rod 12 accidentally falling during high-altitude operations. Furthermore, the locking state of the limit tube 9 is maintained by the force of the spring 11, eliminating the need for additional tools for fastening and reducing the difficulty of operation for workers.

[0095] In this embodiment, please refer to Figure 3 and Figure 4 The safety rope fixing bracket is characterized in that it further includes an L-shaped clamping block 16, a second screw 17, and a second threaded hole 18;

[0096] The vertical end of the L-shaped clamping block 16 is located above the horizontal end of the L-shaped clamping block 16. The L-shaped clamping block 16 moves left and right along the width direction parallel to the I-beam. The vertical plate 102 and the vertical end of the L-shaped clamping block 16 form a clamping space. The clamping space clamps the left and right side walls of the lower flange of the I-beam.

[0097] A second threaded hole 18 is provided on the side wall of the first horizontal plate 101 near the L-shaped clamping block 16, and the axis of the second threaded hole 18 is parallel to the moving direction of the L-shaped clamping block 16.

[0098] One end of the second screw 17 is rotatably connected to the horizontal end of the L-shaped clamping block 16, and the other end of the second screw 17 is located in the second threaded hole 18. The second screw 17 is threadedly connected to the second threaded hole 18.

[0099] In this embodiment, the second screw 17 and the L-shaped clamping block 16 are rotatably connected by a bearing. The horizontal end of the L-shaped clamping block 16 is fixedly installed with a second bearing on one side wall near the first horizontal plate 101. One end of the second screw 17 is fixedly connected to the inner ring of the second bearing by welding.

[0100] In this embodiment, when the second screw 17 is rotated clockwise, the second screw 17 causes the L-shaped clamping block 16 to move towards the first horizontal plate 101 along the axis of the guide screw 17 via the thread. At this time, the side wall of the vertical end of the L-shaped clamping block 16 and the side wall of the vertical plate 102 jointly clamp the side wall of the lower flange of the I-beam. Similarly, when the second screw 17 is rotated counterclockwise, the L-shaped clamping block 16 moves away from the first horizontal plate 101.

[0101] This design increases the clamping capacity of the safety rope fixing bracket for I-beams of different widths, and further enhances the safety rope fixing bracket's ability to resist impact forces along the length of the I-beam.

[0102] In this embodiment, please refer to Figure 3 and Figure 5 The safety rope fixing bracket is characterized in that it further includes a guide post 19 and a guide hole 20;

[0103] A guide hole 20 is provided on the side wall of the first horizontal plate 101 near the L-shaped clamping block 16, and the axis of the guide hole 20 is parallel to the moving direction of the horizontal end of the L-shaped clamping block 16.

[0104] One end of the guide post 19 is fixedly installed on the horizontal end of the L-shaped clamping block 16, and the other end of the guide post 19 slides into the guide hole 20;

[0105] In this embodiment, there are two guide posts 19 and two guide holes 20. The two guide holes 20 are respectively disposed on both sides of the second threaded hole 18, and the two guide holes 20 correspond one-to-one with the two guide posts 19.

[0106] This design reduces the rotation of the L-shaped clamping block 16 when the second screw 17 is rotated, allowing the L-shaped clamping block 16 to slide only along the axis of the guide post 19, thus increasing the stability of the safety rope fixing bracket.

[0107] In this embodiment, please refer to Figure 3 and Figure 5 The safety rope fixing bracket is characterized in that it further includes a guide post limiting block 21 and an annular limiting groove 22;

[0108] An annular limiting groove 22 is provided on the side wall of the guide hole 20. The axis of the annular limiting groove 22 coincides with the axis of the guide hole 20, and the annular limiting groove 22 is connected to the guide hole 20.

[0109] The guide post limiting block 21 slides within the annular limiting groove 22, and the sliding direction of the guide post limiting block 21 is parallel to the axis of the annular limiting groove 22.

[0110] The guide post limiting block 21 is fixedly installed at one end of the guide post 19 located in the guide hole 20;

[0111] Here, the length of the annular limiting groove 22 is less than the length of the guide hole 20, and the part of the annular limiting groove 22 that communicates with the guide hole 20 forms a limiting channel, and the guide post limiting block 21 slides in the limiting channel;

[0112] With this setting, when the second screw 17 is rotated to move the L-shaped clamping block 16 away from the first horizontal plate 101, the guide post limiting block 21 will prevent the guide post 19 from disengaging from the first horizontal plate 101, thereby avoiding the risk of the L-shaped clamping block 16 disconnecting from the first horizontal plate 101.

[0113] In this embodiment, please refer to Figure 4 , Figure 6 and Figure 7 The safety rope fixing bracket is characterized in that it further includes a transmission cavity 23, a first bevel gear 24, a second bevel gear 25, and a first rotating rod 26;

[0114] The L-shaped clamping block 16 has a transmission cavity 23 inside;

[0115] The first rotating rod 26 is rotatably connected to the vertical end of the L-shaped clamping block 16. The rotation axis of the first rotating rod 26 is perpendicular to the rotation direction of the second screw 17. One end of the first rotating rod 26 extends into the transmission cavity 23, and the other end of the first rotating rod 26 is located outside the vertical end of the L-shaped clamping block 16.

[0116] In this embodiment, the first rotating rod 26 and the vertical end of the L-shaped clamping block 16 are rotatably connected by a bearing. A third bearing is fixedly installed on the upper surface of the vertical end of the L-shaped clamping block 16. The outer wall of the first rotating rod 26 is fixedly connected to the inner ring of the third bearing by welding.

[0117] One end of the second screw 17, which is rotatably connected to the horizontal end of the L-shaped clamping block 16, extends into the transmission cavity 23 along the moving direction of the L-shaped clamping block 16.

[0118] The first bevel gear 24 is fixedly mounted on one end of the first rotating rod 26 located in the transmission cavity 23;

[0119] The second bevel gear 25 is fixedly mounted on one end of the second screw 17 located in the transmission cavity 23;

[0120] The first bevel gear 24 and the second bevel gear 25 mesh with each other;

[0121] In this embodiment, when the first rotating rod 26 is rotated clockwise, the first bevel gear 24 rotates clockwise along with the first rotating rod 26. Because 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 to the right of the first bevel gear 24, the first bevel gear 24 drives the second bevel gear 25 to rotate clockwise, which in turn drives the second screw 17 to rotate clockwise. The L-shaped clamping block 16 moves towards the first horizontal plate 101 through the clockwise rotating second screw 17. Similarly, when the first rotating rod 26 is rotated counterclockwise, the L-shaped clamping block 16 moves away from the first horizontal plate 101 through the counterclockwise rotating second screw 17.

[0122] With this setup, the operator only needs to rotate the first rotating rod 26 to indirectly drive the second screw 17 to rotate via gear transmission. This transforms the previously inconvenient method of rotating the second screw 17 horizontally into rotating the first rotating rod 26 vertically, improving the convenience and safety of on-site operations.

[0123] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 7 The safety rope fixing bracket is characterized in that it further includes a second rotating rod 27, a guide groove 28, and a guide protrusion 29;

[0124] The first rotating rod 26 is a hollow rod, one end of the second rotating rod 27 is located inside the first rotating rod 26, and the other end of the second rotating rod 27 extends out of the first rotating rod 26;

[0125] A guide protrusion 29 is fixedly installed on one end of the second rotating rod 27 located inside the first rotating rod 26;

[0126] A guide groove 28 is provided on the inner wall of the first rotating rod 26. The guide groove 28 is slidably connected to the guide protrusion 29. The sliding direction of the guide protrusion 29 is parallel to the rotation axis of the first rotating rod 26.

[0127] Here, a guide groove 28 is provided in the middle of the inner wall of the first rotating rod 26. The guide protrusion 29 contacts the upper wall of the guide groove 28 and prevents the second rotating rod 27 from sliding out of the first rotating rod 26. The guide protrusion 29 cooperates with the guide groove 28 to make the first rotating rod 26 rotate with the second rotating rod 27.

[0128] Here, as Figure 3 The second rotating rod 27 is fixedly equipped with a semi-circular handwheel. When the second rotating rod 27 is pulled upward above the upper surface of the I-beam, the semi-circular handwheel can avoid interference with the upper flange of the I-beam.

[0129] With this setting, when not in operation, 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 could cause the worker to trip and cause accidental operation due to collision. When it is necessary to rotate the first rotating rod 26, the second rotating rod 27 can be slid upward by pulling the handwheel to raise the operating plane of the handwheel, thereby facilitating safe operation by the worker.

[0130] In this embodiment, please refer to Figure 3 The safety rope fixing bracket is characterized in that it further includes several rubber pads 30;

[0131] Several rubber pads 30 are respectively fixedly installed on the lower end face of the first clamping block 3 and the upper end face of the second clamping block 4;

[0132] Here, the material of rubber pad 30 is not limited; it can be neoprene rubber or nitrile rubber.

[0133] By setting rubber pads 30 on the first clamping block 3 and the second clamping block 4, the friction between the first clamping block 3, the second clamping block 4 and the I-beam can be increased, and scratches on the I-beam can be reduced.

[0134] In this embodiment, please refer to Figure 1 and Figure 2 The feature is that a plurality of lifting rings 8 for threading ropes are fixedly installed on the fixed column 5;

[0135] Here, the method of fixing the lifting ring 8 is not limited; it can be welding or threaded connection.

[0136] The specific usage of this embodiment is as follows:

[0137] During installation, the worker first attaches the vertical plate 102 to the side of the lower flange of the I-beam, placing the first horizontal plate 101 below the lower flange and close to its lower end face. Then, the worker pulls the locking rod limiting block 15 outwards and places the first clamping block 3 on the upper end face of the lower flange. After the limiting tube 9 slides and penetrates the second through hole 10, and the locking hole 13 aligns with the locking channel 14, the worker releases the locking rod limiting block 15. The locking rod 12 then resets via the spring 11 and inserts into the locking hole 13. The worker then rotates the first screw 6 clockwise to press the first clamping block 3 against the upper end face of the lower flange and the second clamping block 4 against the lower end face of the upper flange, completing the vertical clamping. Subsequently, the worker... The worker pulls the handwheel upwards to raise it, and rotating the handwheel causes the second rotating rod 27 to rotate clockwise. The second rotating rod 27 then rotates the first rotating rod 26. The first rotating rod 26, through the meshing of the first bevel gear 24 and the second bevel gear 25, causes the second screw 17 to rotate clockwise. The clockwise rotation of the second screw 17 causes the L-shaped clamping block 16 to move towards the first horizontal plate 101, so that the safety rope fixing bracket clamps the left and right side walls of the lower flange of the I-beam, achieving horizontal fixation. The worker then connects the safety rope to the lifting ring 8 on the fixing column 5 and presses down the handwheel to hide it below the surface of the upper flange, ensuring that no protruding parts obstruct passage. During disassembly, the worker first pulls and rotates the handwheel counterclockwise to release the horizontal clamping force of the safety rope fixing bracket on the I-beam, and then rotates the second screw 17 counterclockwise to release the vertical clamping force of the safety rope fixing bracket on the I-beam.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
