Description

Technical Field

[0001] The utility model relates to the technical field of main generator room operating platforms of offshore oil and gas production facilities, in particular to a fully foldable guardrail for a generator room operating platform. Background Art

[0002] Offshore oil and gas production facilities, including fixed platforms and movable platforms, have certain commonalities in the equipment layout of their main generator rooms. Taking the fuel generator room as an example, the room is mainly arranged with the main generator and auxiliary machines. The auxiliary machines mainly include lubricating oil separators, lubricating oil supply pumps, high-temperature water preheaters (plate heat exchangers), central coolers and nozzle coolers, starting air compressors and starting gas cylinders, as well as junction boxes, control cabinets, etc. On the one hand, due to the need for wiring and connecting the auxiliary machines, the equipment is usually required to be arranged in an elevated manner, so that pipelines and cables are laid at the bottom of the equipment; on the other hand, the overall appearance of the main generator is tall, and the staff need to push temporary steps to climb up and check during daily inspections. Therefore, for the convenience of construction and operation, it is currently generally adopted to lay a layer of operating platforms in the main generator room to form a mezzanine, lay equipment on the operating platform, and run pipes and cables under the operating platform. The height of the operating platform from the floor of the room is generally chosen to be about 1.5 meters, and the door of the main generator room is 2 meters high. Considering the problem of equipment entry and exit, a net space of at least 2 meters long and 1.5 meters wide must be left inside the door. An inclined ladder from the ground to the mezzanine of the operating platform is also required. Therefore, a piece of the operating platform needs to be hollowed out at all door positions to ensure that there is enough space for hanging goods inside the door.

[0003] According to safety regulations, guardrails should be installed at the edges of the hollowed-out operating platform of the main generator room. There must be suitable hoisting paths on both sides above each host to ensure that all cylinder heads, pistons, cylinder liners, air coolers, turbochargers and other components of the entire host can be hoisted. In addition, the hoisting of the plate heat exchanger in the auxiliary machine must also be considered. The above equipment will involve daily maintenance work, and the maximum hoisting weight of a single component is about 1.5 tons. Lifting ears are required inside and outside the door of the main generator room, with a height of about 3 meters, for installing manual hoists. When the hoist on the hoist and the hoist at the hoisting ears inside the door cooperate in hoisting, it is necessary to ensure that the hoisting path is arranged appropriately, so that heavy parts can be hoisted to the operating platform of the machine room smoothly; and there are hoisting operations on site that do not use inclined ladders, but directly carry large goods from the operating platform to the door or from the door to the operating platform. If the guardrail of the operating platform is fixed, the height of the guardrail will exceed the door, which will cause great difficulties in lifting the goods. If the lifting is to be carried out smoothly, the guardrail of the operating platform must be bypassed or the guardrail must be temporarily cut, which greatly increases the risk of lifting. Therefore, in order to meet the lifting needs of equipment parts, a traveling crane should also be set up near the door, and the guardrails around the operating platform at all door locations should be detachable. If the guardrail is a conventional plug-in type, the maintenance time of the generator can sometimes be as long as one month, the workload of the staff is heavy, and the frequent plug-in and unplug work will also increase safety hazards.

[0004] From the above, it can be seen that the maintenance of the main generator room equipment takes a long time. If it is strictly carried out in accordance with the requirements of the specifications and operating procedures, the disassembly and assembly of the operating platform guardrail will be very frequent: when the hoisting is in progress, the guardrail needs to be folded up; when the hoisting is over, the guardrail should be returned to the use state to ensure the safety of personnel. Therefore, it is necessary to design a fully foldable guardrail that can be folded and unfolded quickly, has sufficient strength, and does not affect the escape of personnel. Utility Model Content

[0029] This embodiment provides a fully foldable guardrail for a generator room operating platform, such as Figure 1-Figure 5 As shown, it includes a movable leg 1, a fixed leg 2 and a movable railing. The lower end of the movable leg 1 is rotatably connected to the operating platform. The fixed leg 2 is provided on one side of the movable leg 1. The lower end of the fixed leg 2 is connected to the operating platform. One end of the movable railing is rotatably connected to the movable leg 1. A connecting portion is provided on the fixed leg 2 corresponding to the movable railing. The other end of the movable railing is detachably connected to the connecting portion. The movable railing and the connecting portion can be detachably connected by snapping, plugging, magnetic connection, etc. When folding, the movable leg 1 and the movable railing rotate, and the connecting portion of the movable railing and the fixed leg 2 is separated. When unfolding, the movable railing is connected to the connecting portion to keep the whole in the unfolded state. The movable railing is used for grabbing and enclosure protection.

[0030] Specifically, the connecting portion includes a connecting plate 3 and a latch 4. A slot 5 is provided at the upper end of the connecting plate 3. When the movable railing is unfolded, the movable railing enters the slot 5 from above the slot 5. The latch 4 is plugged into one or both sides of the connecting plate 3. When the guardrail is unfolded, the latch 4 is located above the movable railing.

[0031] Furthermore, the latch 4 is connected to the fixed leg 2 through a connecting chain 6. Two connecting ears are welded on the connecting plate 3, and pin holes are provided on the connecting ears. When the movable railing is placed on the connecting plate 3, the latch 4 is inserted into the two pin holes to prevent the movable railing from tilting upward. The latch 4 is tied to the fixed leg 2 with a connecting chain 6.

[0032] Furthermore, a first baffle plate 7 is provided at the other end of the movable railing, and at least one edge of the first baffle plate 7 exceeds the slot 5. A hand ring may be provided on the first baffle plate 7. The length of the movable railing is such that the first baffle plate 7 can just fall on the side of the connecting plate 3 away from the movable leg 1 after the guardrail is opened, and the first baffle plate 7 can limit the retraction of the movable railing.

[0033] Furthermore, the number of the movable railings is multiple, and the length of the movable railings decreases from top to bottom. The number of the fixed legs 2 is 2, and the height of the fixed legs 2 increases in the direction away from the movable legs 1. The lowest movable railing is connected to the connection part of the lower fixed leg 2, and the other movable railings except the lowest one are connected to the connection part of the higher fixed leg 2. In this embodiment, the movable railings preferably include a movable top railing 8, a movable middle railing 9 and a movable bottom railing 10, and a connection part is respectively provided at the upper end and the side of the higher fixed leg 2 for connecting the movable top railing 8 and the movable middle railing 9. The lowest movable bottom railing 10 is located at a lower position and close to the deck surface of the operating platform, so a connection part is provided with a separate lower fixed leg 2 to prevent deformation caused by excessive force on only one fixed leg 2. The lower fixed leg 2 is directly fixed to the deck surface of the operating platform, and its height will not affect the hoisting.

[0034] Furthermore, the lower end of the high fixed leg 2 is detachably connected to the operating platform. The detachable connection can be achieved by plugging, clamping or bolting. The low fixed leg 2 is welded to the outer side of the movable leg 1 close to the edge, and a base 11 is provided on the operating platform. The high fixed leg 2 is connected to the base 11 by bolts. The high fixed leg 2 is arranged on the side of the low fixed leg 2 away from the movable leg 1. A groove is provided on the upper cross section of the fixed leg 2 for fixing the connecting plate 3; the connecting plate 3 is inserted into the groove of the fixed leg 2 and welded, and a U-shaped slot 5 is provided on the connecting plate 3 for placing a movable railing.

[0035] Optionally, a support frame 12 is provided on the side of the movable leg 1 close to the fixed leg 2. The support frame 12 is Z-shaped. The Z-shaped support frame 12 is welded to the movable leg 1. When the movable leg 1 is perpendicular to the deck surface, the bottom of the Z-shaped support frame 12 is in parallel contact with the deck of the operating platform, limiting the movable leg 1 from tipping over to the side close to the fixed leg 2. The support frame 12 in the present application can also be in other shapes, as long as it can play a supporting role on the side of the movable leg 1 close to the fixed leg 2.

[0036] Specifically, the operating platform is provided with a double-ear annular support seat 13 corresponding to the movable leg 1, and the operating platform is rotatably connected with the movable leg 1 through the double-ear annular support seat 13. Optionally, the double-ear annular support seat 13 is welded and fixed to the edge of the deck of the operating platform of the generator room. The leg shaft 14 is used in conjunction with the double-ear annular support seat 13. The movable leg 1 is punched with two holes in the bottom cross-section direction, and the leg shaft 14 is passed through and fixed on the double-ear annular support seat 13 to form a rotating part.

[0037] Specifically, the movable leg 1 is provided with a railing shaft 15, one end of the movable railing is provided with a short section 16, the short section 16 is sleeved on the railing shaft 15, and the end of the railing shaft 15 is provided with a second baffle 17 for blocking the short section 16. Optionally, one end of the railing shaft 15 is welded to the side of the movable leg 1, and the inner diameter of the short section 16 is slightly larger than the outer diameter of the railing shaft 15 to ensure unimpeded rotation in all directions. After the short section 16 of the movable railing is sleeved, the other end of the railing shaft 15 is sealed with a second baffle 17 with a slightly larger diameter.

[0038] In this embodiment, the double-eared annular support seat 13, the fixed legs 2, and the connecting plate 3 constitute the fixed parts of the fully foldable guardrail, and the fixed parts can be installed and removed, but cannot be rotated or folded;

[0039] The leg shaft 14, the movable leg 1, the movable top railing 8, the railing shaft 15, the movable middle railing 9 and the movable bottom railing 10 constitute the movable parts of the fully foldable guardrail, and the movable parts can be rotated, unfolded and folded;

[0040] The Z-shaped support frame 12, the first baffle plate 7, the second baffle plate 17, the latch pin 4, the connecting chain 6, and the pin hole constitute a limiting component of the fully foldable guardrail. The limiting component is used to assist the fixing component to limit the freedom of the railing in all directions so that the unfolded guardrail remains stable.

[0041] like Figure 5 As shown, when the required guardrail length exceeds 1.5 meters, it is recommended to use two sections in combination to control the length of the movable railing within 1.5 meters to avoid deformation or other operational problems caused by excessive length of the movable railing.

[0042] The working process of this embodiment: when the guardrail needs to be opened for use, the support shaft, railing shaft 15, Z-shaped support frame 12, first baffle 7, second baffle 17, and latch 4 limit the freedom of the movable legs 1 and the movable railing in all directions, so that the force is balanced and the guardrail is stable. When the guardrail needs to be folded, unplug the latch 4, lift the movable railing, and lower the guardrail in the direction of contraction. The fixed legs 2 can be removed or retained as needed. The removal of the fixed legs 2 only requires removing the base 11 bolts and removing the fixed legs 2, which is convenient for disassembly and assembly. After folding, the fully foldable guardrail fits the operating platform of the generator room, meeting the space requirements for hoisting and complying with operating procedures.

[0043] The present embodiment has a simple structure, is easy to maintain, and is quick and labor-saving to operate. Since the multi-axis principle is utilized, the extension and retraction of the guardrail is very labor-saving. The card slot and latch fixation allow the guardrail to be quickly assembled and disassembled, greatly improving the safety performance of the guardrail and the comfort of user experience. The rotating parts of the fully foldable guardrail are limited by the Z-shaped support frame, baffle, latch, etc., so that the railing is stable and the legs are evenly stressed. The movable railing is consistent with the appearance of the conventional fixed railing, which is beautiful and coordinated, with standardized design, reliable and durable technology. The fully foldable guardrail is made of commonly used materials on the platform construction site, and there is no need to develop special components separately. It has a wide range of applicability, and can be used in combination with a fixed guardrail or a plurality of folding guardrails, and is applied to situations where the edge of the deck of the generator room operating platform is longer.

[0044] Although the preferred implementation cases of the utility model have been described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the utility model, ordinary technicians in this field can also make many forms of specific changes without departing from the scope of protection of the utility model purpose and claims, which all fall within the scope of protection of the utility model.
