Description

Technical Field

[0001] This invention belongs to the field of safety protection net technology, and specifically relates to a safety net hanging device for industrial plant construction. Background Technology

[0002] During the construction of steel beams, roof trusses, and overhead pipelines in industrial plants, safety nets are usually installed below the work area to support construction workers, tools, or loose materials and reduce the safety risks caused by falls from heights. Safety nets are generally connected to the steel beams of the plant using ropes, hooks, wire ropes, or special clamps. The installation device not only needs to be reliably connected to the steel beams, but also needs to withstand the instantaneous load generated when the safety net is impacted by a fall.

[0003] The existing safety net installation structure still has the following problems in actual use: 1. When the safety net is impacted by falling people or objects, the impact load can be directly transmitted to the steel beam through the side ropes, connecting hooks and steel beam clamps. The hanging point bears a large concentrated load in a short period of time, which can easily cause excessive local stress on the side ropes, connecting parts or clamping parts. 2. Some devices rely solely on the deformation of the safety net itself or a single elastic element for buffering. When the load changes rapidly, it is difficult to simultaneously meet the energy consumption requirements under initial buffering, continuous bearing, and large displacement. Therefore, we propose a safety net hanging device for industrial plant construction to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a safety net hanging device for industrial plant construction, which solves the problem that existing safety net hanging structures are unable to buffer the impact loads on the safety net, thereby reducing the instantaneous concentrated force at the hanging location.

[0005] This invention is achieved through the following solution: a safety net hanging device for industrial plant construction, comprising four hanging structures, respectively connected between the steel beams of the industrial plant and the four corners of the safety net, wherein the hanging structure includes: Locking element, used to secure the steel beam; A buffer mechanism is connected between the locking member and the safety net. The buffer mechanism includes a first sleeve, a second sleeve, a housing, a pressure plate, and an elastic component. The first sleeve is connected to the bottom of the locking member. The housing is fixedly sleeved on the lower end of the first sleeve. The second sleeve is slidably sleeved on the lower end of the first sleeve along the axial direction of the first sleeve, and the second sleeve cannot be axially separated from the first sleeve. The second sleeve is located inside the housing, and the lower end of the second sleeve extends through the housing and to the bottom of the housing. The lower end of the second sleeve is connected to the safety net, and the second sleeve is movably connected to the housing. The pressure plate is fixedly connected to the upper end of the second sleeve, and the outer wall of the pressure plate and the inner wall of the housing are in contact with each other through a friction surface. When the pressure plate and the housing move relative to each other, a frictional damping force is generated between the outer wall of the pressure plate and the inner wall of the housing. The elastic component is located inside the housing and is disposed between the pressure plate and the inner bottom wall of the housing. It is used to provide a reverse force to the pressure plate through elastic deformation when the pressure plate moves towards the inner bottom wall of the housing.

[0006] A further improvement of the safety net hanging device for industrial plant construction of the present invention is that the locking component includes a clamping seat and two clamping blocks. The two clamping blocks are movably connected to the two ends of the clamping seat, and are fixed to the steel beam by moving the two clamping blocks toward each other and clamping them on both sides of the steel beam. The locking component also includes a driving mechanism for driving the two clamping blocks to move toward each other or away from each other.

[0007] A further improvement of the safety net hanging device for industrial plant construction of the present invention is that the driving mechanism includes a bidirectional screw, which is rotatably connected to the clamping seat, and two clamping blocks are respectively screwed to the two ends of the bidirectional screw. By rotating the bidirectional screw, the two clamping blocks can be driven to move towards each other or away from each other.

[0008] A further improvement of the safety net hanging device for industrial plant construction of the present invention is that a rotating handle is fixedly connected to one end of the bidirectional screw.

[0009] A further improvement of the safety net hanging device for industrial plant construction of the present invention is that the steel beam is an I-beam, the two clamping blocks are both inverted L-shaped structures, the vertical sides of the two clamping blocks are respectively clamped on both sides of the lower flange plate of the I-beam, and the horizontal sides of the two clamping blocks are both located above the lower flange plate.

[0010] A further improvement of the safety net hanging device for industrial plant construction of the present invention is that the elastic component includes a disc spring assembly, the disc spring assembly is sleeved on the second sleeve, the pressure plate is fixedly sleeved on the second sleeve, and the pressure plate is fixed above the disc spring assembly, and the disc spring assembly is supported on the inner bottom wall of the housing.

[0011] A further improvement of the safety net hanging device for industrial plant construction of the present invention is that the elastic component further includes an elastic bending plate, and the elastic bending plate is fixedly connected between the inner bottom wall of the shell and the disc spring assembly. The elastic bending plate has a movable opening through the middle, and the elastic bending plate is movably sleeved on the second sleeve through the movable opening.

[0012] A further improvement of the safety net hanging device for industrial plant construction of the present invention is that the cross-sections of the pressure plate and the inside of the shell are non-circular and their shapes are designed to match each other to prevent relative rotation.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention incorporates a buffer mechanism that, when the safety net is impacted, pulls the second sleeve downwards, thereby causing the pressure plate to move downwards. As the pressure plate moves downwards, it generates frictional damping force through the friction surface against the inner wall of the shell. Simultaneously, the downward-moving pressure plate compresses the elastic component, and the impact energy is dissipated sequentially by the deformation of the elastic component. This helps to reduce the degree to which the impact load is directly transmitted to the safety net's side ropes and steel beams. Attached Figure Description

[0021] To address the problem that existing safety net hanging structures are insufficient to buffer impact loads on the safety net and reduce the instantaneous concentrated force at the hanging location, this invention provides a safety net hanging device for industrial plant construction. The following detailed description, in conjunction with the accompanying drawings, provides a specific embodiment of this safety net hanging device for industrial plant construction.

[0022] See Figures 1-6 As shown, a safety net hanging device for industrial plant construction includes four hanging structures, which are respectively connected between the four corners of the steel beam 1 and the safety net 2 of the industrial plant. The hanging structures include: Locking element 3 is used to fix it to the steel beam 1; A buffer mechanism 4 is connected between the locking member 3 and the safety net 2. The buffer mechanism 4 includes a first sleeve 402, a second sleeve 403, a housing 401, a pressure plate 404, and an elastic component. The first sleeve 402 is connected to the bottom of the locking member 3. The housing 401 is fixedly sleeved on the lower end of the first sleeve 402. The second sleeve 403 is slidably sleeved on the lower end of the first sleeve 402 along the axial direction of the first sleeve 402, and the second sleeve 403 cannot be axially separated from the first sleeve 402. The second sleeve 403 is located inside the housing 401, and the lower end of the second sleeve 403 extends through the housing 401 and extends to the bottom of the housing 401. The lower end of the sleeve 403 is connected to the safety net 2, and the second sleeve 403 is movably connected to the housing 401. The pressure plate 404 is fixedly connected to the upper end of the second sleeve 403, and the outer wall of the pressure plate 404 and the inner wall of the housing 401 are in contact with each other through the friction surface 408. When the pressure plate 404 and the housing 401 move relative to each other, a frictional damping force is generated between the outer wall of the pressure plate 404 and the inner wall of the housing 401. The elastic component is located inside the housing 401 and is disposed between the pressure plate 404 and the inner bottom wall of the housing 401. It is used to provide a reverse force to the pressure plate 404 through elastic deformation when the pressure plate 404 moves towards the inner bottom wall of the housing 401.

[0023] By setting a buffer mechanism 4, when the safety net 2 is impacted, the second sleeve 403 will be pulled down, thereby causing the pressure plate 404 to move down. When the pressure plate 404 moves down, it will generate frictional damping force with the inner wall of the shell 401 through the friction surface 408. At the same time, the moving pressure plate 404 will compress the elastic component. The impact energy is consumed in sequence by the deformation of the elastic component, which helps to reduce the degree to which the impact load is directly transmitted to the side rope and steel beam 1 of the safety net 2.

[0024] Among them, see Figure 3 and Figure 4As shown, the locking member 3 includes a clamping seat 301 and two clamping blocks 302. The two clamping blocks 302 are movably connected to the two ends of the clamping seat 301 respectively. By moving the two clamping blocks 302 toward each other and clamping them on both sides of the steel beam 1 respectively, the locking member 3 is fixed to the steel beam 1. The locking component 3 also includes a drive mechanism for driving the two clamping blocks 302 to move toward each other or away from each other.

[0025] Further, see Figure 5 As shown, the clamping seat 301 is fixedly connected to the first sleeve 402 via the first connecting member 5. The first connecting member 5 includes a channel 504, a hanging rod 501, a hook 502, a hanging ring 505, and a pin 503. The channel 504 is formed at the bottom of the clamping seat 301. The hanging rod 501 is fixedly connected to the channel 504, and both ends of the hanging rod 501 are fixedly connected to the two inner walls of the channel 504, respectively. The hanging ring 505 is fixedly connected to the top of the first sleeve 402, and the hook... The entire 502 is bent, and through holes are provided at both ends that are opposite to each other. By passing the hook 502 through the channel 504 and hanging it on the hanging rod 501, and then using the pin 503 to pass through the through hole, the hanging ring 505 and the through hole in sequence and fix it, the clamping seat 301 and the first sleeve 402 can be fixed. With the above design, the clamping seat 301 and the first sleeve 402 can be detachably connected, and the buffer mechanism 4 can swing within a certain range according to the force direction of the safety net 2.

[0026] See Figure 1 and Figure 5 As shown, the second sleeve 403 is fixedly connected to the safety net 2 through the second connector 6. The second connector 6 is a chain and is designed to be detachably connected between the safety net 2 and the second sleeve 403.

[0027] Among them, see Figure 4 As shown, the driving mechanism includes a bidirectional screw 303, which is rotatably connected to the clamping seat 301. Two clamping blocks 302 are respectively screwed to the two ends of the bidirectional screw 303. By rotating the bidirectional screw 303, the two clamping blocks 302 can be driven to move towards each other or away from each other.

[0028] Driven by the bidirectional screw 303, the two clamping blocks 302 can move towards each other to clamp the two sides of the steel beam 1 for fixation. Alternatively, the two clamping blocks 302 can be driven to move away from each other to release the fixation to the steel beam 1 for easy assembly and disassembly. The distance between the two clamping blocks 302 is adjustable to accommodate steel beams 1 of different specifications.

[0029] Furthermore, the bidirectional screw 303 refers to the screw body having threads with opposite directions at both ends, namely, one is a clockwise thread and the other is a counterclockwise thread.

[0030] Among them, see Figure 3 and Figure 4 As shown, a rotating handle 304 is fixedly connected to one end of the bidirectional screw 303.

[0031] The rotating handle 304 facilitates the worker's rotation of the bidirectional screw 303.

[0032] Among them, steel beam 1 is an I-beam, and both clamping blocks 302 adopt an inverted L-shaped structure. The vertical sides of the two clamping blocks 302 are respectively clamped on both sides of the lower flange plate of the I-beam, and the horizontal sides of the two clamping blocks 302 are located above the lower flange plate.

[0033] By adopting the above design, the two vertical sides of the two clamping blocks 302 are used to clamp and fix them on both sides of the lower flange plate, so that the two horizontal sides are located above the lower flange plate, which can greatly improve the clamping firmness between the locking member 3 and the steel beam 1 and increase the load-bearing capacity.

[0034] Further, see Figure 4 As shown, the top of the clamping base 301 is provided with a guide groove 305, the bidirectional screw 303 is rotatably connected in the guide groove 305, and the two clamping blocks 302 are respectively movably connected to the two ends of the guide groove 305, so that the two clamping blocks 302 can move and adjust their positions smoothly.

[0035] Among them, see Figure 5 and 6 As shown, the elastic component includes a disc spring assembly 405, which is sleeved on the second sleeve 403. A pressure plate 404 is fixedly sleeved on the second sleeve 403 and fixed above the disc spring assembly 405. The disc spring assembly 405 is supported on the inner bottom wall of the housing 401.

[0036] By adopting the above design, the second sleeve 403 drives the pressure plate 404 to move downwards, resulting in a more balanced force and improved buffering stability.

[0037] The elastic component also includes an elastic bending plate 406, which is fixedly connected between the inner bottom wall of the housing 401 and the disc spring assembly 405. The elastic bending plate 406 has a movable opening 407 through its middle part, and the elastic bending plate 406 is movably sleeved on the second sleeve 403 through the movable opening 407.

[0038] By combining the disc spring assembly 405 and the elastic bending plate 406, the buffering performance and load-bearing capacity can be greatly improved. The elastic bending plate 406 has good rigidity. When subjected to impact, it will pull the pressure plate 404 downward, first generating frictional damping force between it and the inner wall of the housing 401, and then compressing the disc spring assembly 405. When the force is large, it will compress the elastic bending plate 406, causing it to bend and deform. This forms a graded energy dissipation process that combines friction buffering, elastic buffering, and bending deformation energy dissipation, which can effectively dissipate the energy generated by the impact.

[0039] The cross-sections of the pressure plate 404 and the housing 401 are both non-circular, and their shapes are designed to fit each other to prevent relative rotation.

[0040] By adopting the above design, the pressure plate 404 and the housing 401 cannot rotate relative to each other, thus ensuring the stability of the buffer movement.

[0041] Further, see Figure 5 As shown, the cross-sections of the pressure plate 404 and the housing 401 are quadrilaterals. Friction surfaces 408 are provided on both sides of the pressure plate 404 so that when the pressure plate 404 and the housing 401 move relative to each other, a frictional damping force is generated between the outer wall of the pressure plate 404 and the inner wall of the housing 401.
