Description

Technical Field

[0001] The utility model relates to the technical field of exhaust fans, and in particular to a fixing device for exhaust fans. Background Art

[0002] The existing steelmaking workshop has many high-temperature areas due to the presence of high-temperature molten metal, especially in the hot summer. The power supply and distribution and steelmaking equipment need to be ventilated and cooled according to different heating parts. Some important steelmaking equipment also needs regular overhaul, scheduled repair and maintenance. Exhaust fans are used for ventilation and cooling of important equipment and ventilation and cooling of maintenance workers.

[0009] Optionally, the exhaust fan fixing device further comprises:

[0010] A fixing rod 1 is transversely connected to the inner sleeve, and a collar is provided on one end of the fixing rod 1 away from the inner sleeve;

[0011] A second fixing rod is vertically arranged in the collar and has a top end hinged to the exhaust fan body;

[0012] The fixing frame is a U-shaped frame, the open end of which is rotatably connected to the two sides of the exhaust fan body, and the closed end is connected to the inner sleeve.

[0013] Optionally, the side wall of the collar is provided with a locking bolt, which passes through the collar and is threadedly connected to the side wall of the collar.

[0014] Optionally, the second fixing frame includes:

[0015] One end of the crossbeam is connected to the outer sleeve, and the other end is connected to the side wall of the wall through a fixing seat.

[0016] Optionally, a rotating handle is connected to the bottom of the inner sleeve.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. The utility model provides an exhaust fan fixing device comprising: a fixing frame, which is rotatably connected to the exhaust fan body; an inner sleeve, which is vertically connected to the bottom of the fixing frame; an outer sleeve, which is sleeved on the surface of the inner sleeve; the outer sleeve is connected to the wall through the fixing frame to save space; a fixing bolt passes through the outer sleeve and is threadedly connected to the outer sleeve; by manually rotating or moving the inner sleeve up and down so that it rotates or moves up and down in the outer sleeve, the exhaust fan body can be driven to rotate and adjust the height direction, thereby exhausting and cooling the surrounding areas at different heights, and at the same time, by screwing the fixing bolt into the outer sleeve so that it is pressed against the inner sleeve, the inner sleeve can be fixed, so that the exhaust fan body after position adjustment is fixed.

[0026] Example 1

[0027] Figure 1 FIG. 1 is a schematic diagram of the structure of the exhaust fan fixing device provided in this embodiment. Figure 1 As shown, the exhaust fan fixing device includes: a fixing frame 2, which is rotatably connected to the exhaust fan body 1; an inner sleeve 41, which is vertically connected to the bottom of the fixing frame 2; an outer sleeve 42, which is sleeved on the surface of the inner sleeve 41; the outer sleeve 42 is connected to the wall through a second fixing frame 3; and a fixing bolt 5, which passes through the side wall of the outer sleeve 42 and is threadedly connected to the outer sleeve 42.

[0028] By manually rotating or moving the inner sleeve 41 up and down so that it rotates or moves up and down in the outer sleeve 42, the exhaust fan body 1 can be driven to perform rotation adjustment and height adjustment, thereby exhausting and cooling the surrounding areas at different heights. At the same time, by screwing the fixing bolts 5 into the outer sleeve 42 so that it is pressed against the inner sleeve 41, the inner sleeve 41 can be fixed, so that the exhaust fan body 1 after position adjustment can be fixed.

[0029] In this embodiment, the exhaust fan fixing device also includes a fixing rod 61, which is laterally connected to the inner sleeve 41, and a ring 63 is provided on the end of the fixing rod 61 away from the inner sleeve 41; a fixing rod 62 is vertically arranged in the ring 63 and the top end is hinged to the exhaust fan body 1; the fixing frame 2 is a U-shaped frame, and its open end is rotatably connected to both sides of the exhaust fan body 1, and the closed end is connected to the inner sleeve 41.

[0030] By pulling the fixing rod 62 up and down to move it up and down in the ring 63, the exhaust fan body 1 is driven to swing up and down in the fixing frame 2 to adjust the pitch angle. The fixing frame 2 can be a U-shaped frame welded with a small suitable square tube. The open end of the U-shaped frame is rotatably connected to the two sides of the exhaust fan body 1, and the closed end is connected to the inner sleeve 41, which saves materials and ensures that the exhaust fan body 1 can swing in the fixing frame 2 when the pitch angle is adjusted.

[0031] In this embodiment, a locking bolt 64 is disposed on the side wall of the collar 63 . The locking bolt 64 passes through the collar and is threadedly connected to the side wall of the collar 63 .

[0032] When adjusting the pitch angle, the locking bolt 64 can be screwed into the collar 63 to tighten the fixing rod 62, so that the adjusted fixing rod 62 can be fixed, so that the user does not need to continue to manually fix the exhaust fan body 1 after adjusting the pitch angle.

[0033] In this embodiment, the second fixing frame 3 includes: a crossbeam 31 , one end of which is connected to the outer sleeve 42 , and the other end of which is connected to the side wall of the wall through a fixing seat 32 .

[0034] The fixing seat 32 and the crossbeam 31 are made of suitable steel plates and square tubes to support the weight of the entire device. Where ventilation and heat dissipation are required, they can be welded as a whole to the nearby steel structure or fixed to the reinforced concrete wall with pre-embedded bolts, thereby saving the space occupied by the device.

[0035] In this embodiment, a rotating handle 43 is connected to the bottom of the inner sleeve 41 .

[0036] The user can adjust the inner sleeve 41 up and down and rotate it more conveniently and labor-savingly by adjusting the rotating handle 43 .

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
