Description

Technical Field

[0001] This utility model relates to the field of power plant protection, and in particular to a safety protection device for disassembling the hydraulic cylinder of an emergency door. Background Technology

[0002] During long-term operation of power plants, hydraulic cylinders may experience problems such as oil leakage and jamming due to wear and aging of seals, requiring disassembly and maintenance. During the disassembly of the hydraulic cylinder of the emergency door, the internal spring force can cause the cylinder head and parts to fly off after the screws between the cylinder barrel and cylinder head are removed, which may cause injury. Therefore, safety protection devices are usually installed around the working environment to prevent unauthorized personnel from approaching.

[0003] However, the existing safety fencing in power plants, due to its fixed structural design, requires significant time and manpower for each installation and dismantling operation. This makes it unsuitable for the rapid deployment and evacuation requirements of operations such as the dismantling of hydraulic cylinders for emergency doors, severely slowing down the overall work progress. Furthermore, existing fencing is typically large and structurally indivisible, occupying substantial storage space when not in use. This is particularly problematic in space-constrained environments like power plants, leading to wasted space and potentially hindering the storage and retrieval of other equipment. Therefore, we propose a safety protection device for the dismantling of hydraulic cylinders for emergency doors to address these issues. Utility Model Content

[0004] This utility model provides a safety protection device for disassembling the hydraulic cylinder of the emergency door, which solves the problems of existing safety protection fences in power plants, which consume a lot of time and manpower for installation and disassembly, affecting the efficiency of installation and disassembly and seriously slowing down the overall operation progress; the fences are large in size and the structure cannot be disassembled, which will occupy a lot of storage space when idle, resulting in a waste of space.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a safety protection device for disassembling the hydraulic cylinder of an emergency door, including four lifting side rails, each lifting side rail including two foldable railings, with multiple rotating posts between the two railings, and a locking device between one of the rotating posts and one of the railings. The four lifting side rails are arranged in a rectangular shape, and a support column is provided between adjacent lifting side rails, with the support column engaging with the railing.

[0006] In the preferred embodiment, the railing is provided with multiple rotating seats and multiple through holes, and a threaded hole is provided on one side of each through hole.

[0007] In the preferred embodiment, the lifting side rail includes multiple uprights, which abut against the through holes of the railing. A locking screw is provided in the through hole, and a tightening cap is provided at one end of the locking screw.

[0008] In the preferred embodiment, both ends of the railing are provided with wedge blocks, and both ends of the rotating post are provided with rotating holes. The two ends of the rotating post are rotatably connected to different railings through rotating seats.

[0009] In a preferred embodiment, the locking device includes a fixed sleeve and an mounting sleeve. The fixed sleeve is provided with a sliding handle, which includes a locking pin. The mounting sleeve is provided with a side plate on one side, and a locking hole is provided on the side plate. The locking pin abuts against the locking hole.

[0010] In a preferred embodiment, the fixing sleeve includes an L-shaped sleeve with a sliding groove, and the handle includes an L-shaped handle with one end sliding against the sliding groove.

[0011] In the preferred embodiment, the top of the L-shaped handle is provided with a mounting hole, a spring is provided between the L-shaped handle and the fixing sleeve, and the mounting sleeve includes a sleeve body, which is mounted on the rotating column.

[0012] In the preferred embodiment, the cross-section of the support column is rectangular, the contact surface between the support column and the two lifting side rails is provided with a side groove, the side grooves are provided with limiting springs on both sides, and the side grooves are provided with locking blocks.

[0013] In the preferred embodiment, the wedge block is provided with a wedge groove, the locking block abuts against the wedge groove, and both ends of the wedge block abut against the limiting spring.

[0014] The beneficial effects of this utility model are as follows: When it is necessary to install a protective fence, one of the railings of the lifting side rail is rotated to make multiple rotating posts rotate. Then, the worker presses the handle of the locking device. After the multiple rotating posts are vertical, the handle is released so that the locking post of the handle abuts against the locking hole of the side plate of the mounting sleeve, thereby locking the lifting side rail.

[0015] Insert multiple uprights through the through holes of the lifting side rails, and rotate multiple locking screws to install the lifting side rails together with the multiple lifting side rails.

[0016] Assemble the four lifting side rails into a rectangular structure, and set a support column between two adjacent lifting side rails so that the locking block and the wedge block are connected, and the wedge block abuts against the limiting spring.

[0017] When the overall structure needs to be disassembled, turn all the locking screws, pull out multiple uprights, then disassemble the connection between the lifting side rails and the support columns, press the handle of the locking device to open the locking device, turn the railing to fold the lifting side rails, and multiple folded lifting side rails can be placed side by side, greatly saving space.

[0018] The overall structure is easy and quick to install and disassemble without affecting the efficiency of disassembly and assembly, greatly improving the overall work progress. It can meet the needs of rapid deployment and evacuation of protective devices for operations such as the disassembly of hydraulic cylinders for emergency doors. The overall structure is detachable, so it will not occupy a lot of storage space when idle, which will not easily cause site waste and will not affect the normal storage and retrieval of other equipment.
