Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and in particular to a steel structure safety rope suspension device and its usage method. Background Technology

[0002] In most steel structure building construction processes, H-beams are used for the steel beams, which have advantages such as good load-bearing capacity and good cross-sectional stability. However, during the welding of the top steel beams and the laying of the roof panels, the lack of safety belt suspension points makes it impossible for workers to suspend their safety belts, causing inconvenience for high-altitude construction and posing significant safety hazards to workers at height.

[0003] The traditional method involves directly welding steel pipes or angle steel onto the flanges of H-beams to provide safety rope suspension points for workers at height. This method not only results in poor stability and increases the workload of construction work, but also requires the temporary devices to be dismantled after the work is completed, leading to cumbersome manual operation, increased labor burden, and increased material costs due to the grinding and anti-corrosion treatment of the temporary welding positions. Summary of the Invention

[0004] This invention provides a steel structure safety rope suspension device and its usage method, which effectively ensures the installation stability of the suspension column. The suspension column is stably fixed through threaded connections at both ends. The linear module and moving mechanism facilitate automated driving of the suspension column movement, effectively saving manpower and construction workload. Since the mounting plate is detachably connected to the wing plate, it can be easily disassembled by removing and installing the mounting plate, saving the grinding and anti-corrosion treatment processes of this device and improving operational efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A steel structure safety rope suspension device includes a mounting plate and bolts. The mounting plate has an installation opening, and a hanging column passes through the installation opening. Both ends of the hanging column protrude from the mounting plate. The mounting plate is provided with a moving mechanism for driving the hanging column to move axially. The mounting plate is also provided with a tightening mechanism for driving the bolt to move axially toward the hanging column and tightening the bolt onto the mounting plate.

[0007] Furthermore, the tightening mechanism includes a linear module, an outer cylinder, a straight groove, a spiral groove, a connecting body, an external thread groove, and an internal thread. The outer cylinder is mounted on the mounting plate and coaxially sleeved on the outside of the lifting column. The straight groove is located at the top inner side of the outer cylinder, and the spiral groove is located at the bottom inner side of the outer cylinder. The straight groove and the spiral groove are the same size and interconnected. The connecting body is located on the outside of the bolt and slides into the straight groove. The external thread groove is located on the outside of the lifting column near the outer cylinder. The internal thread is located on the inside of the bolt, and the external thread groove and the internal thread are threaded together. When the connecting body slides into the spiral groove along the straight groove, the external thread groove contacts the internal thread. The linear module is mounted on the mounting plate, and the output end of the linear module is coaxially driven and connected to the bolt. The stroke of the linear module is equal to the distance between the bolt and the mounting plate. The pitch of the spiral groove and the external thread groove are the same.

[0008] Furthermore, the linear module includes a hanger, a lead screw motor module, and a connecting cylinder. The hanger is mounted on the mounting plate, the outer cylinder is located inside the hanger, the lead screw motor module is located on the top inner side of the hanger, the connecting cylinder is coaxially rotatably connected to the outer end face of the bolt, the open end of the connecting cylinder faces the hanging column, the output end of the lead screw motor module is coaxially fixedly connected to the connecting cylinder, and the inner depth of the connecting cylinder is greater than the distance by which the hanging column extends beyond the mounting plate.

[0009] Furthermore, the moving mechanism includes a servo motor, a gear ring, a gear, and a connecting ring. The connecting ring is rotatably connected between the side of the mounting plate away from the outer cylinder and the mounting opening. The lifting column is threaded into the connecting ring. The gear ring is coaxially fixedly connected to the connecting ring. The servo motor is mounted on the mounting plate. The gear is coaxially connected to the output end of the servo motor. The gear meshes with the gear ring. When the gear meshes with the gear ring, the axial movement stroke of the lifting column is greater than the distance between the other end of the lifting column and the mounting opening.

[0010] Furthermore, an annular guide block is provided on the inner side of the mounting port, and the hanging column is fitted into the guide block. An annular guide arc surface is provided at the opening of the guide block.

[0011] The method of using the steel structure safety rope suspension device of the present invention includes the following steps:

[0012] S01. First, the mounting plate is detachably connected to the wing plate and the mounting plate is fixed. Then, the gear is driven to rotate by the drive servo motor. Under the meshing action of the gear and the gear ring, the connecting ring is driven to rotate synchronously. Since the connecting ring is threadedly connected to the hanging column, and the axial movement stroke of the hanging column is greater than the distance between the other end of the hanging column and the mounting port when the gear and the gear ring mesh, it is easy for the other end of the hanging column to extend into the mounting port, so that there is a gap between the hanging column and the mounting port, which is conducive to passing the safety rope through the hanging column.

[0013] S02. Then, the servo motor drives the gear to rotate, causing the other end of the lifting column to pass through the mounting plate and extend into the inner side of the outer cylinder until the end face of the lifting column is flush with the end face of the straight groove. The screw motor module drives the connecting cylinder to rotate, causing the bolt to move towards the lifting column. The bolt slides along the straight groove axially through the connecting body, ensuring smooth movement of the bolt. At the same time as the connecting body slides into the spiral groove along the straight groove, the external thread groove contacts the internal thread, thereby causing the bolt to rotate. Since the pitch of the spiral groove and the external thread groove is the same, it is easy to ensure that the bolt is smoothly screwed into the lifting column at the same time. Since the stroke of the linear module is equal to the distance between the bolt and the mounting plate, it ensures that the inner end face of the bolt can effectively fit against the side of the mounting plate. Specifically, due to the guide block, when the end face of the lifting column passes through the mounting opening, the end of the lifting column and the guide block are flush. The curved surface provides precise guidance for the movement of the lifting column, preventing axial warping at the connection point during insertion and protecting the column's straightness from thermal expansion and contraction due to temperature changes. The inner depth of the connecting sleeve exceeds the distance the lifting column extends beyond the mounting plate, ensuring sufficient space for the bolts to screw into the column and preventing collisions between the column and connecting sleeve during spiral insertion. This effectively guarantees the installation stability of the lifting column. The threaded connection at both ends securely fixes the column, and the linear module and moving mechanism facilitate automated movement, effectively saving manpower and construction effort. The mounting plate is detachably connected to the wing plate, allowing for easy removal and eliminating the need for grinding and anti-corrosion treatment, thus improving operational efficiency.

[0014] The beneficial effects of this invention are:

[0015] It effectively ensures the installation stability of the lifting column, and the lifting column is stably fixed by the threaded connection at both ends. The set linear module and moving mechanism facilitate the automatic driving of the lifting column movement, effectively saving manpower and reducing the amount of construction work. Since the mounting plate is detachably connected to the wing plate, it can be removed and installed, which is convenient for disassembly and saves the grinding and anti-corrosion treatment of this device, thus improving the operating efficiency.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] like Figure 1 , 2 As shown, a steel structure safety rope suspension device includes a mounting plate 1 and bolts 2. The mounting plate 1 has a mounting opening 3, and a hanging column 4 passes through the mounting opening 3. Both ends of the hanging column 4 protrude from the mounting plate 1. The mounting plate 1 is provided with a moving mechanism 5 for driving the hanging column 4 to move axially. The mounting plate 1 is also provided with a tightening mechanism 6, which is used to drive the bolt 2 to move axially toward the hanging column 4 and tighten the bolt 2 onto the mounting plate 1.

[0022] In this embodiment, the tightening mechanism 6 includes a linear module 61, an outer cylinder 62, a straight groove 63, a spiral groove 64, a connecting body 65, an external thread groove 66, and an internal thread 67. The outer cylinder 62 is mounted on the mounting plate 1 and coaxially sleeved on the outside of the hanging column 4. The straight groove 63 is formed at the top inner side of the outer cylinder 62, and the spiral groove 64 is formed at the bottom inner side of the outer cylinder 62. The straight groove 63 and the spiral groove 64 are the same size and interconnected. The connecting body 65 is located on the outside of the bolt 2, and the connecting body 65 slides with the straight groove 63. The external threaded groove 66 is opened on the outer side of the end of the hanging column 4 near the outer cylinder 62. The internal thread 67 is provided on the inner side of the bolt 2. The external threaded groove 66 and the internal thread 67 are threadedly engaged. When the connecting body 65 slides into the spiral groove 64 along the straight groove 63, the external threaded groove 66 contacts the internal thread 67. The linear module 61 is provided on the mounting plate 1. The output end of the linear module 61 is coaxially driven and connected to the bolt 2. The stroke of the linear module 61 is equal to the distance between the bolt 2 and the mounting plate 1. The pitch of the spiral groove 64 and the external threaded groove 66 is the same.

[0023] In this embodiment, the linear module 61 includes a hanger 7, a lead screw motor module 8, and a connecting cylinder 9. The hanger 7 is mounted on the mounting plate 1, the outer cylinder 62 is located inside the hanger 7, the lead screw motor module 8 is located at the top of the inner side of the hanger 7, and the connecting cylinder 9 is coaxially rotatably connected to the outer end face of the bolt 2. The open end of the connecting cylinder 9 faces the hanging column 4, and the output end of the lead screw motor module 8 is coaxially fixedly connected to the connecting cylinder 9. The inner depth of the connecting cylinder 9 is greater than the distance by which the hanging column 4 extends beyond the mounting plate 1.

[0024] In this embodiment, the moving mechanism 5 includes a servo motor 51, a gear ring 52, a gear 53, and a connecting ring 54. The connecting ring 54 is rotatably connected between the side of the mounting plate 1 away from the outer cylinder 62 and the mounting port 3. The hanging column 4 is threadedly connected to the connecting ring 54. The gear ring 52 is coaxially fixedly connected to the connecting ring 54. The servo motor 51 is mounted on the mounting plate 1. The gear 53 is coaxially connected to the output end of the servo motor 51. The gear 53 meshes with the gear ring 52. When the gear 53 meshes with the gear ring 52, the axial movement stroke of the hanging column 4 is greater than the distance between the other end of the hanging column 4 and the mounting port 3.

[0025] In this embodiment, the inner side of the mounting port 3 is provided with an annular guide block 10, the hanging column 4 is fitted into the guide block 10, and the opening of the guide block 10 is provided with an annular guide arc surface 11.

[0026] The method of using the steel structure safety rope suspension device of the present invention includes the following steps:

[0027] like Figure 1 , 2 As shown, S01, firstly, the mounting plate 1 is detachably connected to the wing plate and the mounting plate 1 is fixed. Then, the gear 53 is driven to rotate by the drive servo motor 51. Under the meshing action of the gear 53 and the toothed ring 52, the connecting ring 54 is driven to rotate synchronously. Since the connecting ring 54 is threadedly connected to the hanging column 4, and the axial movement stroke of the hanging column 4 is greater than the distance between the other end of the hanging column 4 and the mounting port 3 when the gear 53 and the toothed ring 52 mesh, it is convenient for the other end of the hanging column 4 to extend into the mounting port 3, so that there is a gap between the hanging column 4 and the mounting port 3, which is conducive to passing the safety rope through the hanging column 4.

[0028] S02. Then, the servo motor 51 drives the gear 53 to rotate, so that the other end of the hanging column 4 passes through the mounting plate 1 and extends into the inner side of the outer cylinder 62 until the end face of the hanging column 4 is flush with the end face of the straight groove 63. The lead screw motor module 8 drives the connecting cylinder 9 to rotate, which drives the bolt 2 to move towards the hanging column 4. The bolt 2 slides along the straight groove 63 axially through the connecting body 65 to ensure the smooth movement of the bolt 2. At the same time, the external thread groove 66 contacts the internal thread 67 while the connecting body 65 slides into the spiral groove 64 along the straight groove 63, so that the bolt 2 rotates. Since the pitch of the spiral groove 64 and the external thread groove 66 is the same, it is easy to ensure that the bolt 2 is smoothly screwed into the hanging column 4 at the same time. Since the stroke of the linear module 61 is equal to the distance between the bolt 2 and the mounting plate 1, it ensures that the inner end face of the bolt 2 can effectively fit against the side of the mounting plate 1. Specifically, since the guide block 10 is provided, the end face of the hanging column 4 along the mounting opening When the penetrating part 3 is inserted, the end of the pendant 4 contacts the guide arc surface 11. The guide arc surface 11 facilitates the precise guidance of the pendant 4's movement, preventing axial warping at the connection point during insertion and preventing the pendant 4's straightness from being affected by thermal expansion and contraction due to temperature changes. Since the inner depth of the connecting cylinder 9 is greater than the distance of the pendant 4 beyond the mounting plate 1, it ensures that the bolt 2 has sufficient space to screw into the pendant 4, avoiding collision between the pendant 4 and the connecting cylinder 9 during the spiral screwing process, thus effectively ensuring the installation stability of the pendant 4. The pendant 4 is stably fixed by the threaded connection at both ends. The linear module 61 and the moving mechanism 5 facilitate the automated driving of the pendant 4's movement, effectively saving manpower and construction workload. Since the mounting plate 1 is detachably connected to the wing plate, it can be removed by simply assembling and disassembling the mounting plate 1, which is convenient for disassembly and saves the grinding and anti-corrosion treatment processes of this device, improving operational efficiency.
