AI Technical Summary
这种结构虽能在常规作业中提供连续防护,但缺乏动态适应性,当进行人工挖孔桩放炮作业时,闭合顶棚会直接承受爆破产生的瞬时冲击波与飞石撞击,其固定连接节点和支撑构件易因应力集中出现局部变形甚至断裂
在本实用新型中,通过动态构型切换实现了安全与效率的双重保障,其核心创新在于采用模块化可开合结构:在常态防护阶段,顶棚呈整体闭合状态,依托高强度钢构框架与抗冲击防护网形成连续屏障,可有效拦截山坡顶部滚落的块石,确保结构稳固;当进行人工挖孔桩放炮作业时,通过驱动组件自动展开棚架,形成镂空泄压通道,使爆破冲击波与飞石从结构间隙分散逸出,避免集中受力导致的构件损伤;而在承台施工等需连续作业的环节,顶棚则恢复全天候封闭模式,为高空作业人员提供全时段防护,真正实现了"一棚多用、动态适配"的智能化安全管控。

Description
Technical Field
[0001] This utility model belongs to the field of hillside construction protection technology, specifically relating to a canopy structure with a combinable roof. Background Technology
[0002] In construction on steep slopes, the design of protective canopies must focus on stability, coverage, and adaptability: the structure must have sufficient strength and rigidity to withstand rockfall impacts, wind and snow loads, and construction vibrations; the coverage area should fully cover the work area and potential rockfall paths to avoid blind spots; in addition, the canopy type should be flexibly selected based on the terrain slope, construction period, and material availability. For example, a lightweight steel structure combined with a high-strength protective net can balance economy and construction efficiency, while a combination of prestressed anchor cables and concrete slabs is suitable for long-term, high-risk projects, ensuring that the protective system dynamically matches the dynamic construction environment.
[0003] In current steep slope construction scenarios, the roof protection system still primarily uses traditional fixed structures with a closed overall design. While this structure provides continuous protection during routine operations, it lacks dynamic adaptability. When manually excavating bored piles and blasting operations are conducted, the closed roof directly bears the instantaneous shock wave and impact from flying rocks generated by the blast. Its fixed connection nodes and supporting components are prone to localized deformation or even breakage due to stress concentration. Simultaneously, ground settlement or structural resonance caused by blasting vibrations may further exacerbate fatigue damage to the roof, shortening its service life. More importantly, because the opening and closing state cannot be flexibly adjusted according to the construction stage, the closed roof requires manual cleaning of residual debris after blasting operations, increasing the risks of working at heights and impacting construction efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a canopy structure with a closable roof. Through the openable and closable structure, it can switch between partial opening for pressure relief during blasting and closed protection during normal operations, balancing safety and construction convenience, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a canopy structure with combinable canopies, including a main frame and two top covers; the top covers are slidably mounted on the main frame, and a driving component is provided on the main frame, which is connected to the top cover in a transmission manner. The driving component drives the top cover to move on the main frame, thereby achieving opening and closing as needed; the total closed area of the two top covers is greater than or equal to the actual protective area in use, thereby ensuring that the closed top cover can play a protective role, and the end faces of the two top covers fit together when closed.
[0006] Preferably, the main frame includes a bottom support frame and two parallel I-beams installed on the top of the bottom support frame. The drive assembly is mounted on the I-beams, and the top cover is slidably mounted on the I-beams. The I-beams support the drive assembly and provide a sliding surface for the wheels.
[0007] Preferably, at least two connecting rods are fixed on both sides of the bottom of the top cover. The inner side of the connecting rod is equipped with a traveling wheel via a shaft. The traveling wheel is rolled in the groove on the outer side of the I-beam. Since the I-beam is I-shaped, and the groove is formed by the structure of the I-beam itself, the traveling wheel on the outer side of the two I-beams can be limited by the I-beams to prevent the top cover from falling off, thus achieving the limitation of the top cover.
[0008] Preferably, there is a gap between the bottom end face of the top cover and the I-beam, and the length of a single top cover is less than half the length of the I-beam, so as to ensure that the top cover can be closed and can also move towards the end of the I-beam when there is an external explosion, so that a gap is formed between the I-beams to facilitate pressure relief.
[0009] Preferably, each of the two adjacent connecting rods of the top cover has a through screw hole. The drive assembly includes a lead screw screwed into the screw hole. A transmission gear is fixed at the end of the lead screw facing the other connecting rod of the top cover. A servo motor is also installed at the bottom end of the I-beam. A drive gear is installed on the output end of the servo motor. The drive gear meshes with the transmission gear. When the top cover needs to be opened or closed, the servo motor is directly started. The drive gear driven by the servo motor drives the transmission gear to rotate. The transmission gear then drives the lead screw, which drives the connecting rod. Finally, the connecting rod drives the traveling wheel to move the top cover, thereby adjusting the opening and closing of the top cover.
[0010] Preferably, the I-beam itself is symmetrically fixed with an integrated mounting plate near the middle position. The inner side of each mounting plate is connected to the other end of the lead screw at the corresponding position. In order to ensure the normal rotation of the lead screw, a bearing sleeve should be provided at the connection point, and the lead screw can be supported by the bearing sleeve.
[0011] Preferably, the bottom surface of the top cover is provided with multiple steel beams, and there is a gap between the steel beams and the top surface of the I-beam. The overall strength of the top cover can be improved by the steel beams.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, a dual guarantee of safety and efficiency is achieved through dynamic configuration switching. Its core innovation lies in the adoption of a modular, openable structure: in the normal protection phase, the canopy is in a completely closed state, relying on a high-strength steel frame and an impact-resistant protective net to form a continuous barrier, which can effectively intercept rocks rolling down from the top of the hillside and ensure structural stability; when manual excavation of bored piles and blasting operations are carried out, the canopy is automatically deployed by the drive components to form a hollow pressure relief channel, allowing the blast shock wave and flying rocks to disperse and escape from the structural gaps, avoiding component damage caused by concentrated force; and in the stages that require continuous operation, such as the construction of the foundation, the canopy returns to a full-weather closed mode, providing all-time protection for high-altitude workers, truly realizing intelligent safety management of "one canopy for multiple uses and dynamic adaptation".

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a canopy structure with a commissible roof, comprising... Main framework; Two top covers, 200; The top cover 200 is slidably mounted on the main frame. A drive component is mounted on the main frame and is connected to the top cover 200 in a transmission manner. The drive component drives the top cover 200 to move on the main frame, thereby opening and closing as needed. The total closed area of the two top covers 200 is greater than or equal to the actual protective area in use, thus ensuring that the closed top covers 200 can play a protective role. When the two top covers 200 are closed, their end faces fit together.
[0017] In this embodiment, preferably, the main frame includes a bottom support frame 100 and two parallel I-beams 101 installed on the top of the bottom support frame 100. The drive assembly is mounted on the I-beams 101, and the top cover 200 is slidably mounted on the I-beams 101. The I-beams 101 support the drive assembly and provide the wheels 202 for sliding.
[0018] In this embodiment, preferably, at least two connecting rods 201 are fixed on both sides of the bottom of the top cover 200. The inner side of the connecting rod 201 is equipped with a traveling wheel 202 via a shaft. The traveling wheel 202 is rolled in the groove on the outer side of the I-beam 101. Since the I-beam 101 is I-shaped, and the groove is formed by the structure of the I-beam 101 itself, the traveling wheel 202 located on the outer side of the two I-beams 101 can be limited by the I-beams 101 to prevent the top cover 200 from falling off, thus achieving the limitation of the top cover 200.
[0019] In this embodiment, preferably, there is a gap between the bottom end face of the top cover 200 and the I-beam 101, and the length of a single top cover 200 is less than half the length of the I-beam 101, so as to ensure that the top cover 200 can be closed, and can also move towards the end of the I-beam 101 when there is an external explosion, so that a gap is formed between the I-beams 101 to facilitate pressure relief.
[0020] In this embodiment, preferably, each of the two adjacent connecting rods 201 of the top cover 200 has a through screw hole. The driving component includes a lead screw 303 screwed into the screw hole. A transmission gear 302 is fixed at the end of the lead screw 303 facing the other connecting rod 201 of the top cover 200. A servo motor 300 is also installed at the bottom end of the I-beam 101. A drive gear 301 is installed on the output end of the servo motor 300. The drive gear 301 is meshed with the transmission gear 302. When the top cover 200 needs to be opened or closed, the servo motor 300 is directly started. The drive gear 301 driven by the servo motor 300 drives the transmission gear 302 to rotate. Then, the transmission gear 302 drives the lead screw 303, so that the lead screw 303 drives the connecting rod 201. Finally, the connecting rod 201 drives the traveling wheel 202 to move the top cover 200, and finally adjusts the opening and closing of the top cover 200.
[0021] In this embodiment, preferably, an integral mounting plate 304 is symmetrically fixed near the middle of the I-beam 101. The inner side of each mounting plate 304 is connected to the other end of the corresponding lead screw 303. In order to ensure the normal rotation of the lead screw 303, a bearing sleeve should be provided at the connection between the two, and the lead screw 303 can be supported by the bearing sleeve.
[0022] In this embodiment, preferably, the bottom surface of the top cover 200 is provided with multiple steel beams, and there is a gap between the steel beams and the top surface of the I-beam 101. By setting the steel beams, the overall strength of the top cover 200 can be improved.
[0023] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
