[0024] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0025] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself; "first" and "second" are used to distinguish one element from another and do not have sequentiality or importance. In addition, the same figure marks in different reference drawings represent the same elements.

[0026] In the present disclosure, an XY coordinate system is established for the walkway grille corridor, wherein the direction indicated by the arrow X may be the first direction, and the direction indicated by the arrow Y may be the length direction of the walkway grille plate 2 .

[0027] The present invention provides a walkway grid corridor, referring to Figures 1 to 5 As shown, the walkway grating corridor includes a steel frame 1, walkway grating plates 2 and a locking mechanism 3. The number of walkway grating plates 2 is not multiple and they are arranged at intervals on the steel frame 1; the locking mechanism 3 is connected to the steel frame 1 and the walkway grating plates 2, and the locking mechanism 3 is used to unlock at least one walkway grating plate 2 to the steel frame 1.

[0028] Through the above-mentioned method, that is, the walkway grille corridor provided by the present invention, when the power plant equipment (such as pipelines, valves or measuring elements) below the walkway grille corridor is inspected and repaired, the walkway grille plate 2 located on the steel frame 1 can be unlocked by the locking mechanism 3, and the walkway grille plate 2 can be easily removed from the steel frame 1 and the power plant equipment can be inspected and repaired. After the inspection and repair is completed, the walkway grille plate 2 that was previously removed can be installed on the steel frame 1 again, and the walkway grille plate 2 can be locked and fixed again by the locking mechanism 3 to complete the installation process of the walkway grille plate 2. The walkway grille plate 2 and the steel frame 1 can be easily disassembled and assembled, so that the walkway grille plate 2 can be easily disassembled and assembled, which can simplify the inspection and repair steps of the power plant equipment and reduce unnecessary waste of resources.

[0029] It should be noted that the walkway grating plates 2 in the walkway grating corridors that are widely present in the prior art are usually fixed by welding to the steel frame 1. For example, as mentioned in the background technology, when it is necessary to overhaul the power plant equipment below the walkway grating plate 2, it is usually necessary to cut and split the walkway grating plate 2 and the steel frame 1 before overhauling. After the overhaul is completed, the walkway grating plate 2 needs to be re-welded to the steel frame 1. This process is time-consuming and labor-intensive. By simply fixing the walkway grating plate 2 in the above manner, the manpower and material resources consumed in cutting and welding can be reduced, thereby simplifying the removal and installation steps of the walkway grating plate 2 and reducing unnecessary waste of resources.

[0030] In addition, the locking mechanism 3 mentioned in the above method can be any structure that can lock the walkway grating plate 2 on the steel frame 1, such as a snap hook, a heavy object press or any other suitable structure. The present disclosure will further elaborate on the specific structure of the locking mechanism 3 below, so I will not go into details here.

[0031] In some embodiments, reference Figures 1 to 5 As shown, a plurality of walkway grating plates 2 are arranged at intervals along a first direction, and the walkway grating corridor includes a plurality of pairs of locking mechanisms 3 arranged at intervals along the first direction, and each pair of locking mechanisms 3 is arranged at opposite ends of the walkway grating plate 2 along the length direction of the walkway grating plate 2. In this way, a plurality of walkway grating plates 2 arranged at intervals along the first direction can together form a walkway for staff to walk on. At the same time, the opposite ends of the walkway grating plate 2 in the length direction are locked by a pair of locking mechanisms 3, that is, it can be understood that each end is locked by a locking mechanism 3, which can further improve the stability of the walkway grating plate 2 being locked on the steel frame 1. At the same time, a plurality of pairs of locking mechanisms 3 can also be arranged in the first direction ( Figure 1 A pair is shown in the figure), and multiple pairs of locking mechanisms 3 can be used to lock multiple walkway grating plates 2 on the steel frame 1, and it is also convenient to unlock and separate the walkway grating plates 2 from the steel frame 1.

[0032] In some embodiments, reference Figures 1 to 5 As shown, the plurality of walkway grating plates 2 include a plurality of pairs of walkway grating plates 2 spaced apart along a first direction, and each pair of walkway grating plates 2 is connected to the steel frame 1 via a pair of locking mechanisms 3. In this way, it is possible to refer to Figure 1 As shown, two walkway grating plates 2 are arranged at intervals along a first direction, and two locking mechanisms 3 are arranged at opposite ends of the walkway grating plates 2 along the length direction of the walkway grating plates 2. One locking mechanism 3 can simultaneously lock the ends of the two walkway grating plates 2 on the same side, thereby making the overall structure of the walkway grating corridor more stable when the locking mechanism 3 locks the walkway grating plates 2.

[0033] In some embodiments, reference Figures 1 to 5 As shown, the locking mechanism 3 includes a limit plate 31 and a connecting assembly 32. The limit plate 31 can be attached to the side of the walkway grating plate 2 away from the steel frame 1 to clamp and fix the walkway grating plate 2 together with the steel frame 1; the connecting assembly 32 is connected to the limit plate 31 and the steel frame 1. In this way, Figure 1 and Figure 2 As shown, the limiting plate 31 can be attached to the surface of the trail grating plate 2 facing away from the steel frame, that is, attached to the upper surface of the trail grating plate 2 to press the trail grating plate 2, and then the trail grating plate 2 can be clamped and fixed by the limiting plate 31 and the steel frame 1. In addition, the connecting component 32 can also keep the relative position of the limiting plate 31 and the steel frame 1 unchanged when the limiting plate 31 and the steel frame 1 jointly clamp the trail grating plate 2, thereby improving the stability of the limiting plate 31 and the steel frame 1 when they jointly clamp the trail grating plate 2.

[0034] It should be noted that the connecting component 32 can be constructed as any suitable structure that can connect the limit plate 31 and the steel frame 1, and the connection relationship between the connecting component 32 and the limit plate 31 and the steel frame 1 can be a fixed connection, or a detachable or adjustable connection. The present disclosure will elaborate on the connecting component 32 in detail below, so no further details will be given here.

[0035] In some embodiments, reference Figures 1 to 5As shown, the limiting plate 31 has an inner surface 312 that fits the walkway grating plate 2, and the inner surface 312 fits at least two walkway grating plates 2. By means of surface-to-surface contact, the limiting plate 31 can be made more stable when cooperating with the steel frame 1 to lock the walkway grating plate 2, and the contact area between the inner surface of the limiting plate 31 and the walkway grating plate 2 can be maintained at one tenth of the surface area of ​​the walkway grating plate 2. Within this range, the limiting plate 31 can lock and fix the walkway grating plate 2 without affecting the walkway grating plate 2 for staff to walk on, and can also reduce or even avoid the occurrence of staff tripping due to excessive contact area between the limiting plate 31 and the walkway grating plate 2, thereby improving the safety of the walkway grating corridor. Among them, the inner surface 312 fits at least two walkway grating plates 2, which can be understood as each limiting plate 31 can press and fix at least two walkway grating plates 2, Figure 1 An embodiment in which the limiting plate 31 presses and fixes two trail grating plates 2 is exemplarily shown. In other embodiments not shown, the limiting plate 31 can also press three, four or more trail grating plates 2 at the same time. The number can be set according to, for example, the number of trail grating plates 2 that need to be removed at the same time to save disassembly and assembly time.

[0036] In some embodiments, reference Figures 1 to 5As shown, the connecting assembly 32 includes a threaded rod 321 and a nut 33. The limiting plate 31 includes a first mounting hole 311 for the threaded rod 321 to pass through. The number of the first mounting holes 311 is multiple and corresponds one-to-one to the number of the threaded rods 321. The nut 33 is located on the side of the limiting plate 31 away from the walkway grating plate 2 and is threadedly connected to the threaded rod 321. When the lock plate 31 is unlocked, the lock plate 31 is unlocked, and the lock plate 31 is unlocked, and the lock plate 31 is unlocked. Moreover, when it is necessary to fix multiple walkway grating plates 2 at the same time, the number of threaded rods 321 and nuts 33 can be multiple corresponding to the walkway grating plates 2, that is, one threaded rod 321 and one nut 33 corresponding to one walkway grating plate 2. When there are many walkway grating plates and the overall length of the walkway grating corridor is long, and when some of the power plant equipment needs to be repaired, it is only necessary to remove the nuts at the corresponding positions and remove the limit plates 31. After removing the corresponding walkway grating plates 2, the power plant equipment can be repaired. After the repair is completed, the walkway grating plates 2 and the limit plates 31 can be reinstalled, so as to simplify the disassembly and assembly steps of the walkway grating plates 2 and facilitate the repair of power plant equipment such as pipelines and valves.

[0037] In some embodiments, reference Figures 1 to 5 As shown, the walkway grating plate 2 includes a second mounting hole 21 that can be passed through by the threaded rod 321 and corresponds one-to-one with the first mounting hole 311. In this way, when the walkway grating plate 2 is locked and fixed, the walkway grating plate 2 can be fixed by opening the second mounting hole 21 on the walkway grating plate 2 and passing the threaded rod 321 through the second mounting hole 21. That is, it can be understood that the cooperation between the second mounting hole 21 and the threaded rod 321 can prevent the walkway grating plate 2 from being limited in the horizontal direction when it is locked. The limit plate 31 presses the walkway grating plate 2 to limit the height direction of the walkway grating plate 2 when the walkway grating plate 2 is locked, thereby allowing the walkway grating plate 2 to be stably clamped between the limit plate 31 and the steel frame 1, thereby allowing staff to walk safely on the walkway grating plate 2. In addition, in order to allow the threaded rod 321 to have a better fit with the first mounting hole 311 and the second mounting hole 21 at the same time, reference is made to FIG. Figure 2 As shown, Figure 2 The example shows an installation case in which two walkway grating plates 2 are respectively penetrated by two threaded rods 321. The distance between the two second mounting holes 21 on the two walkway grating plates 2 should be within the error range of 0 to 1 mm with the distance between the two first mounting holes 311 on the corresponding limit plate 31. Within this error range, multiple threaded rods 321 can pass through multiple first mounting holes 311 and second mounting holes 21 one by one to achieve stable locking of the walkway grating plates 2.

[0038] In some embodiments, reference Figures 1 to 5 As shown, the walkway grating plate 2 also includes a countersunk hole 22 connected to the second mounting hole 21; the connecting assembly 32 also includes a boss 322 connected to one end of the threaded rod 321. The boss 322 is accommodated in the countersunk hole 22 and connected to the steel frame 1. In this way, the boss 322 can be connected to the steel frame 1 and the threaded rod 321, and provide a more stable support effect for the threaded rod 321. The cooperation between the boss 322 and the countersunk hole 22 can also further improve the limiting effect of the walkway grating plate 2, so that the walkway grating plate 2 can be more stably clamped between the steel frame 1 and the limiting plate 31.

[0039] In some embodiments, reference Figures 1 to 5 As shown, the threaded rod 321 extends along the thickness direction of the trail grating plate 2, and the projection area of ​​the boss 322 along the thickness direction is larger than the projection area of ​​the threaded rod 321 along the thickness direction. In this way, the threaded rod 321 extending along the thickness direction of the trail grating plate 2 can make it easier to insert the threaded rod 321 into the second mounting hole 21 to limit and fix the trail grating plate 2. In addition, the projection area of ​​the boss 322 in the thickness direction is larger than the projection area of ​​the threaded rod 321. The boss 322 is equivalent to providing a stable base for the threaded rod 321, so that the threaded rod 321 can be more stably connected to the steel frame 1. In addition, the connection method of the boss 322 to the steel frame 1 can also be any appropriate method. For example, one end of the boss 322 connected to the steel frame 1 can be welded to the steel frame 1, so that the threaded rod 321 can also be stably supported above the boss 322, so as to better cooperate with the trail grating plate 2 and lock and fix the trail grating plate 2.

[0040] In some embodiments, reference Figure 1 and Figure 5 As shown, the threaded rod 321 and / or the nut 33 are constructed of steel. In this way, steel generally has high strength and hardness, and also has good wear resistance. The threaded rod 321 and / or the nut 33 made of steel can better lock the walkway grating plate 2 through its stronger structural strength. The steel can be, for example, carbon steel, alloy steel, or stainless steel, etc., which is not specifically limited in this disclosure.

However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
