Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and more specifically, it relates to a safety guardrail for chemical equipment. Background Technology

[0002] In chemical production environments, temporary or permanent protective barriers are often required around equipment to isolate the risk of leakage of high-temperature, high-pressure, or corrosive substances. Existing protective barriers are mostly installed by bolting or welding, requiring the use of special tools to assemble the posts, crossbars, and guardrail gates one by one. This method is inefficient during equipment maintenance or process adjustment, especially in narrow spaces or explosion-proof areas. The disassembly process may generate sparks, increasing safety hazards. In addition, frequent disassembly and assembly can easily lead to wear on the threads of the connecting parts, reducing structural stability and making it difficult to meet the rapid response requirements of chemical sites.

[0003] Chemical production lines often require replanning of safety zones based on process changes. Existing guardrails and gates are mostly rigidly connected, making it impossible to achieve modular and rapid switching. Utility Model Content

[0008] The present invention is further configured such that a limiting mechanism is provided on the outer side of the fixed sleeve. The limiting mechanism includes a rotating sleeve, a support rod, a limiting hole, and an arc-shaped rod. The rotating sleeve rotates on the outer wall of the fixed sleeve. Multiple sets of support rods are fixed on the outer wall of the rotating sleeve. The limiting hole is provided on the outer wall of multiple sets of support rods. The arc-shaped rod is fixed on the outer wall of multiple sets of mounting blocks. By rotating the rotating sleeve, the engagement state of the limiting hole and the arc-shaped rod can be controlled, thereby realizing the quick locking and unlocking of the disassembly mechanism.

[0009] The present invention is further configured such that a top plate is fixedly provided inside the fixing sleeve, and a compression spring is connected inside the snap-fit ​​sleeve.

[0012] The present invention is further configured such that all of the multiple sets of snap-fit ​​pieces are elastic pieces, and their elastic deformation characteristics enable them to adaptively snap into the card slot and maintain a durable snap-fit ​​force.

[0013] The present invention is further configured such that the top ends of the multiple sets of push plates are all arc-shaped, and the arc end face reduces the contact friction with the snap-fit ​​piece, making the push plate movement smoother.

[0014] The present invention is further provided with rounded corners at the top of the multiple sets of arc-shaped rods and on the outer side of the multiple sets of limiting holes. The rounded corner design reduces wear on the contact surface and extends the service life of the mechanism.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a safety guardrail for chemical equipment, which has the following beneficial effects:

[0017] 1. The connection mechanism of this guardrail achieves rapid and accurate docking between the guardrail body and the guardrail gate through the plug-in cooperation of the fixing block and the snap-fit ​​sleeve, combined with the automatic engagement of the elastic snap-fit ​​piece and the snap-fit ​​slot. The pre-tightening force of the compression spring ensures the stability of the connection, significantly improving the installation efficiency and avoiding the cumbersome operation of traditional bolt fixing.

[0018] 2. The disassembly mechanism uses the elastic reset of the compression spring to push the sliding sleeve to move, so that the push plate synchronously drives the snap-fit ​​piece to disengage from the slot. Combined with the rebound force of the compression spring, the fixed sleeve and the snap-fit ​​sleeve are automatically separated. The whole process does not require tools and can be operated with one hand, which solves the safety hazards of inconvenient disassembly in high-risk chemical environments.

[0019] 3. The limiting mechanism drives the support rod to rotate through the rotating sleeve, so that the locking state of the sliding sleeve is controlled by the engagement or disengagement of the limiting hole and the arc rod. Its rounded corner design reduces frictional resistance, and the tension spring ensures that the rotating sleeve automatically resets. This not only ensures the reliability of the connection state, but also ensures the smoothness of the disassembly action, perfectly adapting to the needs of frequent layout adjustments in chemical equipment.

[0029] Please see Figures 1-5 A safety guardrail for chemical equipment includes a guardrail body 1 and a guardrail gate 2. A connecting mechanism is provided between the guardrail body 1 and the guardrail gate 2. The connecting mechanism includes a fixing block 3, a snap-fit ​​sleeve 4, a connecting plate 5, a fixing sleeve 6, snap-fit ​​pieces 7, a slot 8, and a disassembly mechanism. The fixing block 3 is fixed to the outer wall of the guardrail body 1, the snap-fit ​​sleeve 4 is fixed to the top surface of the fixing block 3, the connecting plate 5 is fixed to the outer wall of the guardrail gate 2 and is inserted into the snap-fit ​​sleeve 4, multiple sets of snap-fit ​​pieces 7 are fixed to the inner wall of the fixing sleeve 6, and multiple sets of slots 8 are distributed in the inner wall of the gate. The outer wall of the snap-fit ​​sleeve 4 and the disassembly mechanism include a slide groove 9, a slide sleeve 10, a push plate 11, a connecting sleeve 12, a mounting block 13 and a compression spring 14. Multiple sets of slide grooves 9 are distributed on the outer wall of the fixed sleeve 6. The slide sleeve 10 slides in multiple sets of slide grooves 9. Multiple sets of push plates 11 are fixed to the inner wall of the slide sleeve 10. The connecting sleeve 12 is fixed to the outer wall of the slide sleeve 10. Multiple sets of mounting blocks 13 are fixed to the outer wall of the connecting sleeve 12. Multiple sets of compression springs 14 are installed on the outer side of the fixed sleeve 6 and their top ends abut against multiple sets of mounting blocks 13.

[0030] A limiting mechanism is provided on the outer side of the fixed sleeve 6. The limiting mechanism includes a rotating sleeve 15, a support rod 16, a limiting hole 17, and an arc-shaped rod 18. The rotating sleeve 15 rotates on the outer wall of the fixed sleeve 6. Multiple sets of support rods 16 are fixed on the outer wall of the rotating sleeve 15. The limiting hole 17 is provided on the outer wall of multiple sets of support rods 16. The arc-shaped rod 18 is fixed on the outer wall of multiple sets of mounting blocks 13. The principle is to rotate the rotating sleeve 15 to drive the support rod 16 to rotate, so that the limiting hole 17 is aligned or misaligned with the arc-shaped rod 18 to limit or release the mounting block 13.

[0031] The top plate 19 is fixed inside the fixed sleeve 6, and the compression spring 20 is connected inside the snap sleeve 4. The principle is that the top plate 19 and the compression spring 20 cooperate to form an elastic buffer structure, which provides pre-tightening force to ensure stability when connected, and achieves automatic separation through spring rebound when disassembled.

[0032] The outer wall of the snap-fit ​​sleeve 4 is provided with a positioning groove 21, and the inner wall of the fixed sleeve 6 is fixed with a positioning plate 22. The positioning groove 21 and the positioning plate 22 are provided in multiple sets and are slidably connected. The principle is to achieve precise alignment between the fixed sleeve 6 and the snap-fit ​​sleeve 4 through the cooperation of multiple sets of positioning grooves 21 and positioning plates 22, so as to prevent displacement during installation.

[0033] Pull blocks 23 are fixedly provided on the top surface of the rotating sleeve 15. Multiple sets of pull blocks 23 are distributed on the top surface of the rotating sleeve 15. Side blocks 24 are fixedly provided on the outer wall of the fixed sleeve 6. Multiple sets of side blocks 24 are provided, and tension springs 25 are connected between each set of pull blocks 23. The principle is that the tension springs 25 provide the automatic reset force of the rotating sleeve 15, so that the limiting mechanism maintains a stable locked state when not in operation.

[0034] All sets of snap-fit ​​pieces 7 are set as elastic pieces. The principle is to use the deformation characteristics of the elastic pieces to achieve automatic engagement and disengagement with the slot 8.

[0035] The tops of the multiple push plates 11 are all set to be arc-shaped. The principle is to reduce the contact friction with the snap-fit ​​piece 7 by using the arc end face, so that the push plate 11 moves more smoothly.

[0036] The top ends of multiple sets of arc-shaped rods 18 and the outer sides of multiple sets of limiting holes 17 are all provided with rounded corners. The principle is that the rounded corner design reduces the wear of the contact surface, improves the service life of the mechanism and the smoothness of operation.

[0037] In this embodiment, when connecting the guardrail body 1 and the guardrail gate 2, the connecting plate 5 and the snap-fit ​​sleeve 4 are inserted, and then the fixing sleeve 6 is inserted into the top of the snap-fit ​​sleeve 4. Multiple sets of snap-fit ​​pieces 7 are pushed by the outer wall of the snap-fit ​​sleeve 4 to deform it. When the multiple sets of snap-fit ​​pieces 7 move to the outside of the slot 8, they are reset and snapped into the slot 8. At this time, the top plate 19 presses the compression spring 20 to complete the connection.

[0038] More specifically, when the guardrail gate 2 needs to be disassembled, rotating the rotating sleeve 15 drives multiple sets of support rods 16 to rotate, causing multiple sets of limiting holes 17 to separate from the arc rod 18 and release the limiting of the sliding sleeve 10. Then, the elastic reset of multiple sets of compression springs 14 pushes the mounting block 13 and the connecting sleeve 12, while driving the sliding sleeve 10 to slide along the slide groove 9 and push multiple sets of snap-fit ​​pieces 7 through multiple sets of push plates 11 to disengage it from the snap-fit ​​groove 8. The reset of the compression spring 20 pushes the fixing sleeve 6 to separate from the snap-fit ​​sleeve 4, and then the connecting plate 5 can be removed from the snap-fit ​​sleeve 4 to complete the disassembly of the guardrail gate 2.

[0039] In summary, when the entire equipment is in use or running: when connecting the guardrail body 1 and the guardrail gate 2, the connecting plate 5 is inserted into the snap-fit ​​sleeve 4, and then the fixing sleeve 6 is inserted into the top of the snap-fit ​​sleeve 4. The snap-fit ​​sleeve 4 pushes multiple sets of snap-fit ​​pieces 7 to deform it. When the multiple sets of snap-fit ​​pieces 7 move to the outside of the slot 8, they are reset and snapped into the slot 8. At this time, the top plate 19 presses the compression spring 20 to complete the connection.

[0040] When the guardrail gate 2 needs to be disassembled, rotating the rotating sleeve 15 drives multiple sets of support rods 16 to rotate, causing multiple sets of limiting holes 17 to separate from the arc rod 18 and release the limiting of the sliding sleeve 10. Then, the elastic reset of multiple sets of compression springs 14 pushes the mounting block 13 and the connecting sleeve 12, while driving the sliding sleeve 10 to slide along the slide groove 9 and pushes multiple sets of snap-fit ​​pieces 7 through multiple sets of push plates 11 to disengage it from the snap-fit ​​groove 8. The reset of the compression spring 20 pushes the fixing sleeve 6 to separate from the snap-fit ​​sleeve 4, and then the connecting plate 5 can be removed from the snap-fit ​​sleeve 4 to complete the disassembly of the guardrail gate 2.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
