Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective device technology, specifically a protective device for chemical safety. Background Technology
[0002] In the chemical production, storage and transportation process, various reaction vessels, pipelines, valves, flange interfaces and other equipment are often in complex and risky environments such as acid and alkali corrosion, chemical splashes and material falls. Special protective devices are needed to isolate and protect critical parts of the equipment or work areas to avoid safety accidents caused by media leakage, component detachment or external collisions, and at the same time ensure the personal safety of operators.
[0003] Currently, safety protection devices commonly used in the chemical industry often adopt an integrated structure, which is heavy and inconvenient to move. Moreover, when a part of it is damaged, the whole device becomes unusable, which easily leads to a waste of resources. Utility Model Content
[0004] (a) Technical problems to be solved In view of the shortcomings of the existing technology, this utility model provides a protective device for chemical safety.
[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a chemical safety protective device, comprising a support assembly and a protective assembly. The support assembly includes a base, a bracket, a support frame, and a limiting member. A bracket is provided above the base, and support frames are symmetrically arranged on the left and right sides of the bracket. A support groove is provided on the side of the support frame away from the bracket. The support assembly is configured as two sets of symmetrically arranged support components. Protective components are provided on the two sets of support frames on the adjacent sides of the two sets of support components. The protective assembly includes a protective frame and a protective net. The left and right sides of the protective frame are inserted into the support groove. The support groove is provided with an upper opening. A limiting member for limiting and fixing the protective frame is also provided on the bracket. The limiting component includes a center seat, a first threaded sleeve, a hinge seat, a hinge plate, a pin sleeve, and a pin. The center seat is located at the center of the upper part of the base, and the first threaded sleeve is located on the center seat. The hinge seats are symmetrically arranged on the left and right sides of the upper part of the base. The hinge seats are provided with hinge plates that can close the openings on the corresponding support grooves. The hinge plates are also provided with pin sleeves that are adapted to the first threaded sleeve in a horizontal state. The pins pass through the pin sleeves and are connected to the first threaded sleeve.
[0006] To ensure the protective frame is positioned, this utility model is improved by providing a first limiting edge on the bottom wall of the support groove, a second limiting edge on the end of the hinge plate away from the pin sleeve, a first limiting groove adapted to the first limiting edge on the protective frame, and a second limiting groove adapted to the second limiting edge on the protective frame.
[0007] Preferably, the pin includes a pin shaft, a stud, and a handle. The two ends of the pin shaft are respectively connected to the stud and the handle, and the stud can be threadedly connected to the first threaded sleeve.
[0008] Preferably, the back side of the bracket is further provided with a second threaded sleeve that is adapted to the pin.
[0009] Preferably, the hinge base is further provided with an auxiliary component for keeping the hinge plate vertical. The auxiliary component includes a side plate and a limiting block. The hinge base is also provided with symmetrically arranged side plates on both sides. A limiting groove is provided on the adjacent side of the two sets of side plates. The hinge plate is also provided with a limiting block that engages with the limiting groove. The limiting block is arc-shaped.
[0010] Preferably, the handle is provided with friction texture.
[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a chemical safety protection device with the following advantages: This chemical safety protective device consists of two sets of symmetrical support components and independent protective components. The protective components are connected to the support frames via insert slots, eliminating the need for transporting the entire device as a whole. The weight of each support and protective component is distributed, making it easier for a single person to move, transport, and deploy on-site compared to a one-piece structure. The protective and support components are independent modules. When the protective net (such as due to chemical corrosion or heavy object impact) or a single support component (such as a hinge plate or pin) is partially damaged, it is not necessary to replace the entire device. Only the damaged module needs to be disassembled and replaced individually. This avoids the resource waste problem of "partial damage and overall scrapping" of an integrated structure and significantly reduces the later maintenance and procurement costs.

[0014] 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.
[0015] Please see Figures 1-4 A chemical safety protective device includes a support assembly and a protective assembly. The support assembly includes a base 1, a bracket 2, a support frame 3, and a limiting member. The bracket 2 is arranged above the base 1. The support frames 3 are symmetrically arranged on the left and right sides of the bracket 2. The support frame 3 has a support groove on the side away from the bracket 2. The support assembly is arranged in two symmetrical sets. The two sets of support frames 3 on the adjacent sides of the two sets of support assemblies are provided with a protective assembly. The protective assembly includes a protective frame 4 and a protective net 5. The left and right sides of the protective frame 4 are inserted into the support groove. The support groove has an upper opening. The bracket 2 is also provided with a limiting member for limiting and fixing the protective frame 4. The limiting component includes a center seat 6, a first threaded sleeve 7, a hinge seat 8, a hinge plate 9, a pin sleeve 10, and a pin. The center seat 6 is located at the center of the upper part of the base 1. The first threaded sleeve 7 is provided on the center seat 6. The hinge seats 8 are symmetrically arranged on the left and right sides of the upper part of the base 1. The hinge plate 9 is provided on the hinge seat 8, which can close the opening on the corresponding support groove. The pin sleeve 10 is also provided on the hinge plate 9, which is adapted to the first threaded sleeve 7 in a horizontal state. The pin passes through the pin sleeve 10 and is connected to the first threaded sleeve 7.
[0016] The device consists of two symmetrical support components and an independent protective component. The support components provide stable support through the base 1, and the support frames 3 on both sides of the bracket 2 are equipped with open support slots. The protective frames 4 of the protective component can be directly inserted into the support slots on both sides, enabling rapid assembly without the need for overall handling. The weight of each module is distributed, allowing for movement and deployment by a single person, and adapting to the protection range requirements of different chemical equipment (reactors, pipelines, flange interfaces). The base 1 has a large contact area with the ground and can be fixed with bolts (optional) or placed stably by its own weight. The bracket 2 and the support frame 3 are integrated to ensure that there is no deformation or shaking when supporting the protective components, providing a stable foundation for subsequent protection. In this embodiment, a first limiting edge 11 is provided on the bottom wall of the support groove, and a second limiting edge 12 is also provided on the end of the hinge plate 9 away from the pin sleeve 10. A first limiting groove adapted to the first limiting edge 11 is provided on the protective frame 4, and a second limiting groove adapted to the second limiting edge 12 is also provided on the protective frame 4. In this embodiment, the pin includes a pin shaft 13, a stud 14, and a handle 15. The two ends of the pin shaft 13 are respectively connected to the stud 14 and the handle 15. The stud 14 can be threadedly connected to the first threaded sleeve 7. Initially, the corresponding hinge plate 9 is in a vertical position, and the protective frame 4 with the protective net 5 can be inserted into the corresponding support groove. At this time, the first limiting edge 11 is inserted into the first limiting groove, and the hinge plate 9 on the hinge seat 8 can be rotated around the hinge point. After the protective frame 4 is inserted into the support groove, the hinge plate 9 is rotated to a horizontal position, and the second limiting edge 12 at its end is engaged with the second limiting groove of the protective frame 4, closing the opening on the support groove and restricting the removal of the protective frame 4 from the top. At this time, the pin sleeve 10 on the hinge plate 9 is coaxially aligned with the first threaded sleeve 7 of the center seat 6. The stud 14 of the pin passes through the pin sleeve 10 and is threadedly connected to the first threaded sleeve 7. The two sets of hinge plates 9 are firmly fixed by the thread locking force, forming a double fixing structure of "bottom engagement + top locking" to resist workshop vibration, external force collision and media impact.
[0017] The second screw sleeve 16 on the back side of the bracket 2 can store the pin when the hinge plate 9 is opened, preventing the pin from being lost; the friction texture 19 on the handle 15 increases the grip friction, making it convenient for operators to quickly tighten or loosen the pin without additional tools.
[0018] In actual use, the hinge base 8 is also equipped with auxiliary components for keeping the hinge plate 9 vertical. The auxiliary components include side plates 18 and limiting blocks 17. Side plates 18 are symmetrically arranged on both sides of the hinge base 8. Limiting grooves are provided on the adjacent sides of the two sets of side plates 18. The hinge plate 9 is also equipped with limiting blocks 17 that engage with the limiting grooves. The limiting blocks 17 are arc-shaped. The side plates 18 on both sides of the hinge base 8 are provided with limiting grooves. When the hinge plate 9 is flipped to the vertical state, the arc-shaped limiting blocks 17 on the hinge plate 9 engage with the limiting grooves. The hinge plate 9 is kept in the open state by friction and the engaging structure. The insertion and removal of the protective components can be completed without manual support. A single person can operate independently, improving the efficiency of installation and disassembly.
