Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude operation protection, and particularly relates to an edge protection structure for high-altitude operation at a construction site. Background Art

[0002] In the modern construction industry, high-altitude operation is an inevitable construction link, which is highly dangerous and has extremely strict safety protection requirements for construction workers. Traditional edge protection structures for high-altitude operation at construction sites mostly adopt fixed fences or railings. Although these structures provide certain safety guarantees to a certain extent, there are many inconveniences and limitations in the actual construction process. For example, fixed protection structures cannot flexibly adjust the protection range according to the actual needs of the operation area, and when the operation area changes or the construction height changes, it is necessary to reinstall or adjust the protection structure, which not only increases the construction cost but also reduces the work efficiency.

[0003] In addition, traditional protection structures often ignore the space requirements of construction workers on the operating platform. When performing high-altitude operations, if the operating platform is far from the construction area, in order to better complete the operation, construction workers may unconsciously stretch their bodies out of the edge of the operating platform, which undoubtedly greatly increases the risk of safety accidents such as falling. Although some existing designs attempt to solve this problem by increasing the platform area, these solutions often have defects such as complex structures, inconvenient installation, high costs, etc., and it is difficult to achieve flexible expansion of space while ensuring the structural stability. Therefore, in view of the above technical problems, an edge protection structure for high-altitude operation at a construction site is proposed here. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an edge protection structure for high-altitude operation at a construction site, which can automatically raise the side plates and the protection plate, thereby improving the overall protection performance of the operating platform, avoiding accidents, and can automatically adjust the internal space of the operating platform to prevent the situation where workers stretch their bodies out and cause danger.

[0005] The utility model is realized through the following technical solutions:

[0006] An edge protection structure for high-altitude operation at a construction site, comprising:

[0007] An operating platform, on which an installation groove is opened on the upper side;

[0008] A protection plate, which is slidably connected to the inside of the installation groove. Side plates are fixedly connected to both sides of the protection plate. A protection net is opened on the outside of the side plates, and a toothed plate is fixedly connected to the outside of the side plates;

[0009] A driving motor, which is fixedly connected to the outside of the operating platform, and a lifting mechanism is installed inside the installation groove;

[0010] An extension table is slidably connected to the bottom of the operating table. A sliding rod is fixedly connected to the upper side of the extension table, and a positioning mechanism is installed inside the operating table.

[0011] Preferably, the lifting mechanism includes a rotating rod and a gear. The rotating rod is rotatably connected inside the installation groove, and the rotating rod is fixedly connected to the driving motor. The gear is fixedly connected to the outside of the rotating rod.

[0012] Preferably, the gear meshes with the toothed plate.

[0013] Preferably, a sliding groove is formed at the bottom of the operating table, and the sliding rod is slidably connected to the sliding groove.

[0014] Preferably, a connecting plate is fixedly connected to the upper side of the sliding rod.

[0015] Preferably, the number of the connecting plates is two and they are arranged horizontally, and a connecting rod is fixedly connected between the two connecting plates.

[0016] Preferably, the positioning mechanism includes a screw hole and a fastening bolt. The screw hole is formed inside the operating table, and the number of the screw holes is several groups and they are arranged at equal intervals. The fastening bolt passes through the connecting plate and is threadedly connected to the inside of the screw hole.

[0017] The technical solution of the present utility model has at least the following beneficial effects:

[0018] 1. For the edge protection structure for high-altitude operations at the construction site, when the staff stands on the operating table for high-altitude operations, in order to ensure the safety of the construction personnel, the driving motor can be operated to drive the rotating rod to drive the gear to rotate. Since the gear meshes with the toothed plate, the toothed plate can drive the side plate to rise, and the protection plate can be lifted together, thereby improving the overall protection performance of the operating table and avoiding accidents.

[0019] 2. For the edge protection structure for high-altitude operations at the construction site, by unscrewing the fastening bolt above the connecting plate to release the sliding rod so that it can slide in the sliding groove, the extension table can be slid outwards to expand the internal space of the operating table. At this time, the fastening bolt is installed through the corresponding screw hole. Through the positioning of the two connecting plates and the connecting rod, it can be ensured that the extension table can be firmly connected to the operating table, so that the internal space can be adjusted by itself, and the situation that the staff stretches out their bodies and causes danger can be avoided.

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] Embodiment 1

[0027] Please refer to Figures 1-3 , a temporary edge protection structure for high-altitude operations at the construction site proposed by the present application, including an operating platform 1, a protection plate 3, a driving motor 7 and an extension table 10. An installation groove 2 is opened on the upper side of the operating platform 1;

[0028] The protection plate 3 is slidably connected to the inside of the installation groove 2. Side plates 4 are fixedly connected to both sides of the protection plate 3. A protection net 5 is opened on the outside of the side plates 4. A tooth plate 6 is fixedly connected to the outside of the side plates 4;

[0029] The driving motor 7 is fixedly connected to the outside of the operating platform 1. A lifting mechanism is installed inside the installation groove 2.

[0030] The lifting mechanism includes a rotating rod 8 and a gear 9. The rotating rod 8 is rotatably connected to the inside of the installation groove 2, and the rotating rod 8 is fixedly connected to the driving motor 7. The gear 9 is fixedly connected to the outside of the rotating rod 8.

[0031] The gear 9 meshes with the tooth plate 6.

[0032] The working principle of the edge protection structure for high-altitude work at the construction site based on Embodiment 1 is that when a worker stands on the operating platform 1 for high-altitude work, to ensure the safety of the construction workers, the driving motor 7 can be operated to drive the rotating rod 8 to drive the gear 9 to rotate. Since the gear 9 meshes with the toothed plate 6, the toothed plate 6 can drive the side plate 4 to rise, and the protective plate 3 will be raised together, thereby improving the overall protection performance of the operating platform 1 and avoiding accidents. When the workers finish construction and leave the operating platform 1, the driving motor 7 can be reversed to drive the toothed plate 6 to descend, and the side plate 4 and the protective plate 3 can be controlled to be received into the installation groove 2, which is convenient for installation and transportation.

[0033] Embodiment 2

[0034] Please refer to Figures 1-4 , based on Embodiment 1, the extension platform 10 is slidably connected to the bottom of the operating platform 1. A sliding rod 12 is fixedly connected to the upper side of the extension platform 10, and a positioning mechanism is installed inside the operating platform 1.

[0035] A chute 11 is opened at the bottom of the operating platform 1, and the sliding rod 12 is slidably connected to the chute 11.

[0036] A connecting plate 13 is fixedly connected to the upper side of the sliding rod 12.

[0037] The number of the connecting plates 13 is two groups and they are arranged horizontally, and a connecting rod 14 is fixedly connected between the two groups of connecting plates 13.

[0038] The positioning mechanism includes a screw hole 15 and a fastening bolt 16. The screw hole 15 is opened inside the operating platform 1, and the number of the screw holes 15 is several groups and they are arranged at equal intervals. The fastening bolt 16 passes through the connecting plate 13 and is threadedly connected to the inside of the screw hole 15.

[0039] In this embodiment, when a construction worker is performing high-altitude work on the operating platform 1, if there is still a certain distance between the operating platform 1 and the construction area, usually the worker will stretch out his body for construction. At this time, to ensure the safety of the construction worker, the fastening bolt 16 above the connecting plate 13 can be unscrewed to release the sliding rod 12 so that it can slide in the chute 11, then the extension platform 10 can be slid outwards to expand the internal space of the operating platform 1. At this time, the fastening bolt 16 is installed through the corresponding screw hole 15. Through the positioning of the two groups of connecting plates 13 and the connecting rod 14, it can be ensured that the extension platform 10 can be firmly connected to the operating platform 1, so that the internal space can be adjusted by itself, and the situation that the worker stretches out his body and causes danger can be avoided.

[0040] Although embodiments of the present application have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
