Description

Technical Field

[0001] This utility model relates to the field of building protection, specifically to a new type of safety protection device for building engineering. Background Technology

[0002] Carpentry work is frequently required during construction, such as making concrete pouring formwork and scaffolding. Rebar processing is also necessary, such as welding and bending steel bars. These operations are usually carried out near the building. During construction, there is always the possibility of objects falling from the sky and causing personal injury to construction workers. Therefore, safety sheds must be erected to protect construction workers when carrying out carpentry and rebar work on construction sites.

[0003] Safety is paramount in modern construction engineering. Construction sites often present various potential safety risks, such as falling objects from heights and accidental collapses, all of which can seriously threaten the lives of workers on site. Existing protective sheds are mostly steel pipe structures. In the event of a sudden falling object, the steel pipes cannot provide sufficient support for the shed. If the falling object lands directly on the shed, it can cause the shed to collapse, resulting in injury to people below. Utility Model Content

[0004] In view of this, the present invention provides a novel safety protection device for construction engineering. Through the combined use of protective components and buffer components, it can effectively prevent injury to construction workers from falling objects from heights. At the same time, the protective canopy is raised and lowered by a cylinder to ensure rapid deployment during construction. The design of the lead screw and slider in the slide groove, combined with the hydraulic push rod and tension spring, can effectively absorb energy when impacted, reducing injury to construction workers. The position of the slider is adjusted by the tension spring, so that the buffer component can be dynamically adjusted according to different impact forces, thereby improving the buffering effect.

[0005] To solve the above-mentioned technical problems, this utility model provides a new type of safety protection device for construction engineering, including two telescopic frames arranged symmetrically, and a protective mechanism for the safety of construction site personnel is fixed on the telescopic frames. The protective mechanism includes a load-bearing plate, and a protective component and buffer components symmetrically arranged on both sides of the protective component are fixed on the load-bearing plate.

[0006] The protective component includes a crossbeam mounted on a load-bearing plate, with cylinders symmetrically mounted on the crossbeam, and a protective canopy connected to the end of the telescopic shaft of the cylinder; the buffer component includes a slide groove mounted on one side of the crossbeam, with a lead screw fixed in the slide groove, a slider sliding on the lead screw, a hydraulic push rod connected to the slider, a connecting rod connected to the hydraulic push rod, and support modules for supporting the protective canopy connected to both ends of the connecting rod.

[0007] By combining protective and cushioning components, the system effectively prevents injuries to construction workers from falling objects. The protective canopy is raised and lowered using cylinders, allowing for rapid deployment before construction begins and providing protection for subsequent work.

[0008] The protective canopy is connected to the cylinder via a connecting plate, and the protective canopy is connected to the load-bearing plate via four symmetrically arranged dampers. The connection between the protective canopy and the load-bearing plate via four dampers increases the stability of the structure and reduces the impact of vibration and shock.

[0009] A tension spring for sliding block movement is fixed inside the chute. One end of the tension spring is connected to the side of the crossbeam, and the other end is connected to the side of the slider. A connecting block is connected to the output shaft end of the hydraulic push rod, and the connecting rod is set in the through hole of the connecting block. By combining the hydraulic push rod and the tension spring, energy can be effectively absorbed when subjected to impact, reducing injury to construction personnel. Furthermore, the slider can slide on the lead screw and be adjusted by the tension spring, allowing the buffer assembly to be dynamically adjusted according to different impact forces, thereby improving the buffering effect.

[0010] The support module includes a pulley bracket mounted on a load-bearing plate. The bracket has a fixed shaft, and a rocker arm is connected to the fixed shaft. The rocker arm is connected to a connecting rod, and a load-bearing wheel for supporting the protective canopy is connected to the tail end of the rocker arm.

[0011] One side of the load-bearing plate is provided with a protrusion for expansion connection, and the other side of the load-bearing plate is provided with a groove for expansion connection. The groove and the protrusion are provided with threaded through holes for bolt connection. Through the reserved threaded through holes, it is convenient to use bolts for connection and reinforcement, so that multiple protective devices can be quickly connected together to expand the protection area and adapt to construction sites of different sizes.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. By using protective and buffer components together, the impact of falling objects from heights can be effectively mitigated, thus preventing injury to construction workers.

[0014] 2. By pre-reserving grooves, protrusions, and threaded through holes on the load-bearing plate, it is easy to use bolts for reinforcement, enabling it to be quickly connected to multiple protective devices, expanding the protection area, and adapting to different construction sites.

[0015] 3. By installing buffer components at the bottom of the protective canopy, the overall stability of the structure is enhanced, which can effectively reduce the impact of falling objects from heights and absorb energy when impacted, thus reducing injury to construction workers.

A protective component 25 and a buffer component 26 symmetrically arranged on both sides of the protective component 25 are fixed on the load-bearing plate 21.

[0023] The protective component 25 includes a crossbeam 251 mounted on a load-bearing plate 21, with cylinders 252 symmetrically mounted on the crossbeam 251, and a protective canopy 255 connected to the end of the telescopic shaft of the cylinders 252; the buffer component 26 includes a slide groove 261 mounted on one side of the crossbeam 251, with a lead screw 262 fixed inside the slide groove 261, a slider 263 sliding on the lead screw 262, a hydraulic push rod 264 connected to the slider 263, a connecting rod 265 connected to the hydraulic push rod 264, and a support module 268 for supporting the protective canopy 255 connected to both ends of the connecting rod 265.

[0024] By combining the protective component 25 and the buffer component 26, it is possible to effectively prevent injuries to construction site personnel from falling objects. The protective canopy 255 is raised and lowered under the control of the cylinder 252, and can be quickly deployed before construction begins to provide protection for subsequent construction.

[0025] The protective canopy 255 is connected to the cylinder 252 through the connecting plate 253, and the protective canopy 255 is connected to the load-bearing plate 21 through four symmetrically arranged dampers 254. The protective canopy 255 and the load-bearing plate 21 are connected by four dampers 254, which increases the stability of the structure and reduces the impact of vibration and impact.

[0026] A tension spring 267 for moving the slider 263 is fixedly installed inside the slide 261. One end of the tension spring 267 is connected to the side of the crossbeam 251, and the other end is connected to the side of the slider 263. A connecting block 266 is connected to the output shaft end of the hydraulic push rod 264. A connecting rod 265 is installed in the through hole of the connecting block 266.
