Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective device technology, specifically a blasting protective device for building demolition. Background Technology
[0002] Currently, the main method used for demolishing dilapidated and old buildings is blasting. As we all know, blasting demolition generates a large amount of flying rocks, smoke, noise, and powerful shock waves. In order to protect residents near the blasting material, it is necessary to expand the protection zone and build simple protective walls. If the blasting material is located in the city, expanding the protection zone will be very inconvenient, so only slow mechanical demolition can be chosen. In order to safely reduce the protection zone near the blasting material, different protective devices have emerged in this technical field.
[0003] In response, Chinese patent application number CN221992552U discloses a blasting protection device for building demolition, comprising a frame with a honeycomb panel on the inner wall and a sponge pad fixed to one side of the honeycomb panel. Multiple rotating shafts evenly distributed along the vertical direction are located within the frame, with buffer plates rotatably connected to the shafts. A sliding groove is formed at the top of the frame, within which a top plate is slidably connected. A support rod is hinged to one side of the top plate, and a positioning rod is hinged to the bottom of the support rod. The free end of the positioning rod is connected to the bottom of the frame by bolts. When transporting this device, the positioning rod can be disassembled from the frame by loosening the bolts, allowing the top plate to slide out of the frame, thus enabling separate transport of the frame and support mechanisms such as the support rod, facilitating handling. Alternatively, the positioning rod can be disassembled from the frame, and the support rod and positioning rod can be folded, reducing the space occupied during transport. The honeycomb panel and sponge pad also help reduce noise to some extent.
[0004] However, existing blasting protection devices for building demolition require blasting during demolition, and the existing devices rely on protective devices for protection. Furthermore, the existing devices cannot adjust the angle of the protective components as needed when providing protection, and they are also inconvenient to move.
[0005] Therefore, in order to solve the above problems, a blasting protection device for building demolition is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a blasting protection device for building demolition, so as to solve the problems mentioned in the background art of the prior art for building demolition blasting protection devices. Since blasting is required when demolishing a building, the existing device is protected by a protective device, and the existing device cannot adjust the angle of the protective component as needed when providing protection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The device incorporates a buffer mechanism to cushion the impact on the protective components.

The first and second limiting blocks further support the first and second fixed rods. When the protective components are impacted, they can move on the first and second fixed rods via the first and second sliding sleeves. This movement causes the first and second springs to contract, thus providing cushioning and improving the device's practicality.

The upper end of the protective components is supported and limited by the second hinge assembly and the support rod, and the connecting rod is supported and limited by the third hinge assembly. The rivets on the connecting rod are used to work, thereby supporting and limiting the worktable, thus protecting the workers behind and improving the working efficiency of the device.
