Description
Technical Field
[0001] This utility model belongs to the field of maintenance technology, and in particular to a safety protection device for the maintenance of oil refining equipment. Background Technology
[0002] In oil refining and chemical production enterprises, it is often necessary to inspect and maintain oil refining and chemical equipment. Most of the equipment is large-scale, and when inspecting large-scale equipment, it is necessary to set up a work scaffold. The maintenance personnel stand on the work scaffold to carry out the maintenance. Therefore, safety protection devices for oil refining equipment maintenance are required. Traditional protection devices do not have a blocking function and cannot guarantee the safety of oil refining maintenance.
[0003] A search revealed a Chinese patent document (authorization announcement number CN212583184U) for a work frame for oil refining equipment maintenance. The frame includes a base, columns, and a standing plate. The base comprises a lower base plate and an upper base plate. The lower base plate has wheels at its bottom, and supports are positioned between the lower and upper base plates. A spring is fixed between the lower and upper base plates, and the spring is sleeved on the supports. A slider is positioned between a lower support block and an upper support block. Lower and upper sliders are mounted on the lower and upper base plates, and sliding plates are mounted on them. A screw is mounted on the sliding plate and threadedly connected to the slider. A column is mounted on the upper base plate, and a standing plate is secured to the column. This technical solution ensures stable support for the work frame, preventing wobbling and reducing the risk of maintenance personnel falling. When maintaining large equipment, a work frame needs to be erected, and maintenance personnel stand on it for maintenance. Therefore, a safety protection device for oil refining equipment maintenance is necessary. Traditional protective devices lack a blocking function and cannot guarantee the safety of oil refining maintenance. Utility Model Content

[0035] Please see Figures 1 to 4 As shown, a safety protection device for the maintenance of oil refining equipment, in this embodiment including:
[0036] Support platform 1 is used to support personnel and equipment for maintenance of oil refining equipment;
[0037] The counterweight frame 2 is connected and fixed to the support platform 1 by multiple adjusting parts 3;
[0038] Four connecting rods 4 are welded to the top of the support platform 1. Linear motors 5 are embedded in the outer periphery of two of the connecting rods 4 on one side. The moving parts of the two linear motors 5 are connected to a stabilizing plate 6. Slide rails are installed on the top and side of the stabilizing plate 6. Sliding sliders are slidably connected to the two slide rails. The two sliders are connected to an L-shaped connecting plate 7.
[0039] The protective main plate 8 is fixedly connected to the bottom of the connecting plate 7 and is used for safety protection during oil refining maintenance. A protective secondary plate 9 is rotatably connected to one side of the protective main plate 8 through a friction-type rotating structure. The protective main plate 8 is connected and fixed to the protective secondary plate 9 by a latch. A limit block 10 is connected to the side of the protective main plate 8 to limit the excessive rotation of the protective secondary plate 9. According to the maintenance and protection needs, the linear motor 5 is adjusted to drive the stabilizing plate 6, the connecting plate 7 and the protective main plate 8 to move. The position of the slider and the connecting plate 7 is adjusted to change the position of the protective main plate 8 relative to the stabilizing plate 6. The protective secondary plate 9 is rotated so that the protective secondary plate 9 and the protective main plate 8 can provide safety protection during oil refining equipment maintenance.
[0040] Friction-driven rotation structures are mechanical structures that rely on friction to transmit motion and power. The following will introduce them from the perspectives of principle, types, and application scenarios. Working principle: Power is transmitted from one component to another through the friction between two or more contacting surfaces under pressure, causing them to rotate relative to each other. During normal operation, the driving component drives the driven component to rotate due to friction. To prevent slippage, sufficiently high friction is required at the contact points. This can be achieved by using springs, force-applying devices, or lining the working surface of the friction wheel with materials such as asbestos, leather, or rubber.
[0041] Each of the multiple adjusting components 3 includes:
[0042] Hollow tube 31 is fixedly connected to the bottom end of support platform 1;
[0043] The movable rod 32 is fixedly connected to the top of the counterweight frame 2;
[0044] The hollow tube 31 has a threaded channel on its side, and a fixed threaded rod 33 is threadedly connected to the threaded channel. The movable rod 32 has multiple circular channels on its outer periphery for the fixed threaded rod 33 to pass through. Multiple workers can lift the four hollow tubes 31 together as needed and fix them with the fixed threaded rod 33, or use a lifting device to lift them up.
[0045] To meet usage requirements, the bottom of the counterweight frame 2 is connected to multiple brake casters 34. When in use, push the brake casters 34 to the designated position, adjust the orientation of the protective main board 8, and activate the brakes on the brake casters 34. The hollow tube 31 of one of the adjusting components 3 and the support platform 1 are connected to an auxiliary frame 35. The inner wall of the auxiliary frame 35 is connected to multiple anti-climbing slip plates 36. The staff climbs up the anti-climbing slip plates 36 to the support platform 1 and then closes the two protective frames 11.
[0046] For protection and blocking, two of the connecting rods 4 on one side are rotatably connected to protective frames 11. The two protective frames 11 are fixed by a locking mechanism. Three connecting rods 4 are connected to an L-shaped upper connecting plate 12. A vertical support plate 13 is connected between the upper connecting plate 12 and the support platform 1.
[0047] The linear motor 5 is a conventional instrument, and its working principle, size, and model are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0048] Working principle
[0049] This safety protection device for refining equipment maintenance allows multiple workers to lift four hollow tubes 31 together as needed, and secure them using threaded rods 33. When needed, the brake caster 34 is pushed to the designated position, the orientation of the protective main plate 8 is adjusted, and the brake caster 34 is engaged. Workers climb onto the support platform 1 via the anti-slip plate 36, then close the two protective frames 11. According to maintenance and protection needs, the linear motor 5 is adjusted to move the stabilizing plate 6, connecting plate 7, and protective main plate 8. The positions of the slider and connecting plate 7 are adjusted to change the position of the protective main plate 8 relative to the stabilizing plate 6. The protective auxiliary plate 9 is rotated to provide safety protection during refining equipment maintenance between the protective auxiliary plate 9 and the protective main plate 8.
