Description

Technical Field

[0001] The utility model belongs to the technical field of container parts, and in particular relates to a new type of manhole component suitable for a container. Background Art

[0002] A manhole is an opening structure used for personnel to enter and exit equipment for installation, maintenance and safety inspection. A manhole cover of a suitable shape is used to close the manhole and allow access to the manhole when maintenance is required. At present, most manhole covers are flap-type, such as one side of the manhole cover is hinged to the other side of the manhole through a hinge. When in use, the manhole cover can be opened by lifting it from the unhinged side; there are also some that adopt the following method: Figure 1 The manhole structure is shown, a suspension rod 101 is fixed above the manhole cover 100, and the other end of the suspension rod can rotate. When the manhole cover is opened or closed, the manhole cover rotates around the rotating end of the suspension rod to open or close the manhole. However, the manhole cover is generally made of metal such as iron, so that the weight of the manhole cover is generally very large. Therefore, it is very difficult for the staff to open it by flipping the cover, and the stability of the manhole cover during the opening and closing process is not high when the suspension rod is used. Therefore, further research on the manhole opening and closing method is needed to solve the above problems. Utility Model Content

[0026] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0027] See also Figure 2-6 As shown, a new type of manhole assembly is located outside the container and is used for transferring the manhole cover 10, that is, transferring the manhole cover 10 to the manhole flange 11 so that the manhole cover 10 forms a cover on the manhole flange 11, or separating the manhole cover 10 from the manhole flange 11 so that the manhole flange 11 is in an open state. It includes a fixing assembly 12 that provides a fixed supporting position, and a bearing assembly 15 having a connecting end 13 and a free end 14, and a movable setting or a pivot setting is formed between the connecting end 13 of the bearing assembly 15 and the fixing assembly 12; a transferring assembly 16 is arranged on the bearing assembly 15, and the transferring assembly 16 forms a reciprocating motion between the connecting end 13 and the free end 14 of the bearing assembly 15; a connecting assembly 17 is arranged on the transferring assembly 16, and the connecting assembly 17 is connected to the manhole cover 10; the movement direction of the free end 14 of the bearing assembly 15 is different from the movement direction of the transferring assembly 16.

[0028] When the connecting section of the bearing assembly 15 is moved between the fixing assembly 12, the bearing assembly 15 as a whole can form a reciprocating movement process relative to the fixing assembly 12; when the manhole cover 10 and the manhole flange 11 are in a closed state and need to be opened, the manhole cover 10 is moved toward the outside of the container by operating the manhole cover 10, that is, the transfer assembly 16 moves the manhole cover 10 toward the outside to separate the manhole cover 10 from the manhole flange 11, and then the bearing assembly 15 and the manhole cover 10 are changed into a closed state through the moving relationship between the bearing assembly 15 and the fixing assembly 12. Switch to movement in another direction to stagger the manhole cover 10 and the manhole flange 11, thereby realizing the opening process of the manhole cover 10; when the manhole cover 10 and the manhole flange 11 are in the open state and need to be sealed, the manhole cover 10 is first moved to a position aligned with the manhole flange 11 by the bearing assembly 15, and then the manhole cover 10 is driven toward the manhole flange 11 by the transfer assembly 16 for docking, and the manhole cover 10 and the manhole flange 11 are connected and fixed by bolts to realize the sealing process of the manhole cover 10.

[0029] When the bearing assembly 15 and the fixing assembly 12 are pivotally connected, the bearing assembly 15 as a whole can form a reciprocating swing process relative to the fixing assembly 12; different from the opening and closing process of the manhole cover 10 above, the bearing assembly 15 carries the manhole cover 10 and forms a swinging movement centered at the pivot point, that is, during the opening process of the manhole cover 10, the swinging movement is to one side of the container; during the closing process of the manhole cover 10, the swinging movement is to a position aligned with the manhole flange 11.

[0030] In some implementations, the fixing component 12 in the present application can be welded or bolted to the outer wall of the container; the fixing component 12 can also adopt a fixing bracket that has no fixed relationship with the container and is located on the outside of the container. The specific arrangement position only needs to provide stable support for the load-bearing component 15.

Here, it can be understood that the fixed component 12 contains a horizontally arranged guide rail, and the connection end 13 of the bearing component 15 is arranged on the guide rail by a slider or a roller in a common moving manner, so that the bearing component 15 can move toward one side of the container under the guidance of the guide rail; Figure 1 In terms of the direction shown, the transfer assembly 16 can move in the left-right direction, while the bearing assembly 15 can move in the front-back direction.

[0032] In some implementations, such as when the above-mentioned fixing component 12 mainly provides a moving position for the bearing component 15, another guide rail can also be set at the free end 14 of the bearing component 15 to support the movement of the free end 14 of the bearing component 15, so that the movement stability of the bearing component 15 in the front and rear directions can be further improved.

[0033] In some implementations, the fixing assembly 12 provides a pivoting position for the bearing assembly 15, and the connection end 13 of the bearing assembly 15 is rotatably connected to the fixing assembly 12 through a pivot member.
