[0014] Figure 1 It is a perspective view of the positioning device for the shaft air duct provided in this application. Detailed Description of the Embodiment

[0015] The present utility model will be further described in detail below in conjunction with the drawings through specific embodiments. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many details are described to enable a better understanding of this application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to this application are not shown or described in the specification, which is to avoid the core part of this application being overwhelmed by excessive description. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0016] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment, and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0017] The serial numbers assigned to the components in this text itself, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0018] When installing the air duct in the shaft, it is usually temporarily fixed by a lifting rope, and then manual labor is used to fix the air duct. Due to the instability of the lifting rope, the air duct will shift during installation, which will further cause deviation when two air ducts are butted. Secondly, the air duct is heavy and there is a safety hazard of falling off.

[0019] In view of the above problems, this application provides a positioning device for the shaft air duct, which uses rods to connect the shaft and the air duct, and can improve the fixing strength of the air duct to firmly fix the air duct.

[0020] See Figure 1 As shown, the positioning device for the shaft air duct provided by this application is mainly used for positioning the air duct in the vertical shaft. The positioning device for the shaft air duct includes a plurality of rods 10. The plurality of rods 10 are circumferentially and equally distributed around the air duct 200. One end of the rod 10 is connected to the shaft 100, and the other end of the rod 10 is connected to the air duct 200 to position the air duct 200 at the center of the shaft 100.

[0021] In this embodiment, the rod 10 has a certain structural strength. The plurality of rods 10 are arranged around the air duct 200 in a circumferentially equally divided manner. One end of the rod 10 is connected to the shaft 100, and the other end of the rod 10 is connected to the air duct 200, which can form a stable support for the air duct 200. Each rod 10 can be considered to have the same length, that is, the air duct 200 can be positioned at the center of the shaft 100 through the rod 10. In a preferred embodiment, the shaft 100 and the air duct 200 can be kept in a coaxial state. In this way, when two air ducts 200 are butted and connected, the air duct 200 can be prevented from shifting, so as to improve the construction efficiency.

[0022] In an embodiment of this application, one end of the rod 10 is detachably connected to the shaft 100, and the other end of the rod 10 is detachably connected to the air duct 200. In this way, the positioning device can be recycled and reused to reduce the construction cost.

[0023] Continue to see Figure 1 As shown, the positioning device for the shaft air duct provided in this embodiment further includes an annular clamp 20. The annular clamp 20 is fixed on the outer wall of the air duct 200. Among them, the shape of the annular clamp 20 is the same as the shape and size of the air duct 200, and the annular clamp 20 is connected to the air duct 200 in a tight fit manner. The other end of the rod 10 is connected to the annular clamp 20, and the air duct 200 and the rod 10 can be connected by means of the annular clamp 20.

[0024] In some embodiments, a plurality of card slots 21 are provided on the annular clamp 20 (the card slots 21 are blocked in the figure), and the plurality of card slots 21 respectively correspond to the plurality of rods 10 one by one, and the other ends of the respective rods 10 are connected to the card slots 21.

[0025] In this embodiment, the other end of the rod 10 is detachably connected to the card slot 21. In a specific embodiment, the other end of the rod 10 can be snapped into the card slot 21 to achieve detachable connection.

[0026] In another embodiment of the present application, a fastening hole (not shown in the figure) is provided at the other end of the rod 10, and a through hole (not shown in the figure) is provided along the axial direction of the air duct 200 in the card slot 21 of the annular clamp 20. The other end of the rod 10 is inserted into the card slot 21, and the fastening hole and the through hole are coaxially arranged, so as to be fixed by passing a fastener through the fastening hole and the through hole.

[0027] Specifically, the fastener can be a bolt. After the fastener is passed through the coaxial fastening hole and through hole, the fastener can be fastened by a nut.

[0028] In an embodiment of the present application, the annular clamp 20 includes at least two hoop members, and the at least two hoop members are connected end to end to be fixed on the outer wall of the air duct 200. After the at least two hoop members are connected end to end, an annular clamp 20 having substantially the same cross-sectional shape as the air duct 200 can be formed. The method of forming the annular clamp 20 by using at least two hoop members can reduce the manufacturing difficulty of the annular clamp 20 and facilitate the assembly and disassembly of the product.

[0029] Continue to refer to Figure 1 As shown, a connection seat 13 is provided at one end of the rod 10, and at least one connection hole is provided in the connection seat 13. The rod 10 is fixed by passing a fastener through the connection hole and fixing it to the shaft tunnel 100, so that one end of the rod 10 is detachably connected to the shaft tunnel 100.

[0030] In the present application, the rod 10 is a telescopic rod, so as to adjust the position of the air duct 200 in the shaft tunnel 100 by adjusting the telescopic amount of the rod 10. In this way, the two butted air ducts 200 can be aligned to facilitate the operation of the construction personnel.

[0031] In this embodiment, the telescopic rod 10 includes a fixed rod 11 and a movable rod 12. The inside of the fixed rod 11 has a telescopic channel, and the movable rod 12 is reciprocally slidably arranged in the telescopic channel, so as to achieve the telescopic function.

[0032] It should be noted that the movable rod 12 can be positioned at the position after telescoping during the telescoping process to maintain the telescopic amount.

[0033] In summary, for the positioning device of the air duct in the suspended shaft provided by the present application, the rod has a certain structural strength. A plurality of rods are arranged around the air duct in a circumferentially equally divided manner. One end of the rod is connected to the shaft, and the other end of the rod is connected to the air duct, which can form a stable support for the air duct. Each rod can be considered to have the same length, that is, the air duct can be positioned at the center of the shaft through the rods, and then the shaft and the air duct can be kept in a coaxial state. In this way, when connecting two air ducts butt-jointly, the air duct can be prevented from shifting, so as to improve the construction efficiency.

[0034] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model.
