Description

Technical Field

[0001] This utility model relates to the field of elevator safety equipment technology, and in particular to a horizontal protection device for elevator shafts used in elevator engineering. Background Technology

[0002] During the elevator installation and building construction phases, the elevator shaft, as a vertical passage running through the building, presents an extremely high risk of falling due to its unobstructed vertical space.

[0003] Existing devices mostly use a purely rigid structure without a dedicated cushioning design. When a falling object impacts the device, the impact force is directly and rigidly transmitted to the main frame and the fixing points on the well wall, which can easily lead to frame deformation, weld cracking, or even the detachment of the pre-embedded anchor points on the well wall. This requires frequent maintenance or replacement, increasing construction costs and downtime.

[0004] Therefore, it is necessary to provide a horizontal protection device for elevator shafts in elevator engineering to solve the above-mentioned technical problems. Summary of the Invention

[0005] This utility model provides a horizontal protection device for elevator shafts in elevator engineering, which solves the problems of weak impact load resistance and easy structural damage of existing protection devices.

[0006] To solve the above-mentioned technical problems, the present invention provides a horizontal protection device for elevator shafts in elevator engineering, comprising: a protection component, buffer and obstruction components installed at both ends of the protection component, the buffer and obstruction components being used for pre-protection against external materials, telescopic sliding components installed on the inner walls of both ends of the buffer and obstruction components, elastic buffer components symmetrically installed on the top of the protection component, the elastic buffer components being used for buffering and resetting the obstruction components, and guide components installed on the side ends of the elastic buffer components.

[0007] Preferably, the protective component includes a fixed frame, a protective structure installed on the inner wall of the fixed frame for protecting against falling impurities, and fastening structures installed at both ends of the fixed frame for structural fastening of the fixed frame.

[0008] Preferably, the buffering and obstructing assembly includes a support frame and an auxiliary protective structure. Rotating components are installed on the inner walls of both ends of the support frame. An installation structure is rotatably connected to the inner wall of the rotating component. The installation structure is used for the structural installation of the auxiliary protective structure. The auxiliary protective structure is disposed between the inner walls of the installation structure. An elastic reset structure is installed on the side end of the rotating component.

[0009] Preferably, the telescopic sliding assembly includes a rotating structure, a rotating support block is rotatably connected to the inner wall of the rotating structure, a telescopic structure is installed between the inner walls of the rotating support block, the telescopic structure is used for telescopic adjustment of the rotating support block, and a positioning plate is installed on the inner wall of the rotating structure at the left end.

[0010] Preferably, the elastic buffer assembly includes a guide frame, the guide frame has a fixed groove structure, an elastic damping structure is installed at the bottom of the fixed groove structure, the elastic damping structure is used for elastic support of the buffer and obstruction assembly, an elastic support structure is sleeved on the side end of the elastic damping structure, and a reset support plate is installed on the top of the elastic damping structure.

[0011] Preferably, the guide assembly includes a mounting frame, a guide rod structure is mounted on the inner wall of the mounting frame, and a guide groove structure is formed on the inner wall of the side end of the telescopic sliding assembly. The guide rod structure, in conjunction with the guide groove structure, can be used to guide the structure of the buffer and obstruction assembly.

[0012] Compared with related technologies, the elevator shaft horizontal protection device for elevator engineering provided by this utility model has the following beneficial effects: This utility model provides a horizontal protection device for elevator shafts in elevator engineering. During installation and use, to improve the protective effect, the device utilizes a combination of buffer and elastic buffer components to initially physically block falling objects or impurities, extending their contact time and pre-dispersing some impact energy. This prevents the impact force from directly concentrating on a single structure. Combined with the deformation characteristics of the elastic buffer components, it further absorbs remaining kinetic energy, transforming instantaneous rigid impact into progressive elastic buffering. This significantly reduces the load on the main frame, fixed connectors, and embedded structures of the elevator shaft wall caused by the impact peak, reducing structural damage such as frame deformation, weld cracking, or loosening of fixing points, and extending the overall service life of the device.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

Figure 3 for Figure 1 The diagram shows the structural schematic of the protective structure. Figure 4 for Figure 1 The diagram shows the structure of the reset support plate. Figure 5 for Figure 1 The diagram shows the structure of the elastic buffer assembly. An elevator shaft horizontal protection device for elevator engineering includes: a protective assembly 1, with buffering and obstructing assemblies 2 installed at both ends of the protective assembly 1. The buffering and obstructing assemblies 2 are used for pre-protection against external materials.

The fastening structures 13 are used to secure the structure of the fixed frame 11.

[0018] When the device is used for protection, the position of the frame 11 can be fixed by the fastening structure 13 at both ends to provide stable installation conditions.

[0019] Among them, the protective component 1 includes, but is not limited to, wire rope protection and grid protection; in this embodiment, the protective component 1 is preferably grid protection.

[0020] The buffer and obstruction assembly 2 includes a support frame 21 and an auxiliary protection structure 24.

The auxiliary protection structure 24 is disposed between the inner walls of the installation structure 23. An elastic reset structure 25 is installed on the side end of the rotating component 22.

[0021] When protecting falling objects, the auxiliary protective structure 24 on the inner wall will reduce the impact of the falling objects in advance, thereby reducing the damage to the protective component 1 caused by the instantaneous impact. In addition, the elastic reset structure 25 at both ends can elastically reset the auxiliary protective structure 24 to ensure the elastic buffer of the structure.

[0022] Among them, the buffering and blocking component 2 includes, but is not limited to, rigid blocking components and elastic blocking components; in this embodiment, the buffering and blocking component 2 is preferably an elastic blocking component.

[0023] The telescopic sliding assembly 3 includes a rotating structure 31, with a rotating support block 32 rotatably connected to the inner wall of the rotating structure 31. A telescopic structure 33 is installed between the inner walls of the rotating support block 32. The telescopic structure 33 is used for the telescopic adjustment of the rotating support block 32. A positioning plate 34 is installed on the inner wall of the rotating structure 31 at the left end.

[0024] When the top buffer component 2 provides elastic buffering, the rotating structures 31 at both ends slide on the inner wall of the elastic buffer component 4 to ensure the accurate positioning of the structure. In addition, the telescopic structure 33 on the inner wall can reduce the occurrence of jamming in the structure.

[0025] The telescopic sliding component 3 includes, but is not limited to, a comb plate telescopic component and a slider telescopic component; in this embodiment, the telescopic sliding component 3 is preferably a slider telescopic component.

[0026] The elastic buffer assembly 4 includes a guide frame 41, the guide frame 41 has a fixed groove structure 42, the bottom of the fixed groove structure 42 is equipped with an elastic damping structure 43, the elastic damping structure 43 is used for the elastic support of the buffer and obstruction assembly 2, the side end of the elastic damping structure 43 is fitted with an elastic support structure 44, and the top of the elastic damping structure 43 is equipped with a reset support plate 45.

[0027] When the top structure is providing elastic cushioning, the elastic damping structure 43 and elastic support structure 44 on the inner walls at both ends can provide elastic support to reduce damage to the structure and ensure the next cushioning support.

[0029] The guide component 5 includes a mounting frame 51, a guide rod structure 52 is mounted on the inner wall of the mounting frame 51, and a guide groove structure 53 is formed on the inner wall of the side end of the telescopic sliding component 3. The guide rod structure 52, in conjunction with the guide groove structure 53, can be used to guide the structure of the buffer and obstruction component 2.

[0030] When the telescopic sliding assembly 3 slides in position, the guide rod structure 52 on the inner wall and the opened guide groove structure 53 can reduce the positional deviation of the moving workpiece.

[0031] The guide component 5 includes, but is not limited to, guide post and guide sleeve guide and slide rail guide components; in this embodiment, the guide component 5 is preferably guided by guide post and guide sleeve.

[0032] The working principle of the elevator shaft horizontal protection device for elevator engineering provided by this utility model is as follows: During installation and use, the entire protective component 1 can be pre-installed on the inner wall of the elevator shaft for protection. When objects or impurities fall, the buffer and obstruction component 2 on the inner wall can absorb the impact force generated during the fall, thereby reducing the impact pressure on the protective component 1. Secondly, when the buffer and obstruction component 2 performs buffering and obstruction, the telescopic sliding components 3 at both ends will slide along the inner wall of the elastic buffer component 4, and the elastic buffer component 4 will provide elastic support for the telescopic sliding component 3 to ensure the next buffer absorption. When the structure is performing sliding buffering, the guide component 5 on the inner wall can reduce the workpiece deviation phenomenon in the structure.

[0033] Compared with related technologies, the elevator shaft horizontal protection device for elevator engineering provided by this utility model has the following beneficial effects: In order to improve the protective effect of the elevator shaft protection device, the buffer obstruction component 2 and the elastic buffer component 4 are used together to first form a preliminary physical blockage against falling objects or impurities, prolonging their falling contact time and dispersing some of the impact energy in advance, avoiding the impact force from directly concentrating on a single structure. With the deformation characteristics of the elastic buffer component 4, the remaining kinetic energy can be further absorbed, transforming the instantaneous rigid impact into a gradual elastic buffer, which greatly reduces the load of the impact peak on the main frame of the protection device, fixed connectors and the pre-embedded structure of the elevator shaft wall, reduces structural losses such as frame deformation, weld cracking or loosening of fixing points, and extends the overall service life of the device.
