[0023] See also Figure 1 The embodiment of the utility model provides a large-span steel structure sliding structure, including a plurality of support units 1 and a slide rail 2. The support unit 1 includes a seat body 4, a sliding portion 5, a first support portion 6, a second support portion 8 and a track support portion 7. The seat body 4 is arranged on a building body 3. The seat body 4 is provided with a slide hole. The slide portion 5 is passed through the slide hole. The first support portion 6 is rotatably connected to the slide portion 5. The second support portion 8 is rotatably connected to the seat body 4. The first support portion 6 and the second support portion 8 are coaxially rotatably connected to the track support portion 7. The slide rail 2 is connected to the track support portion 7.

[0024] A plurality of support units 1 may be arranged at intervals along the extending direction of the slide rail 2 , and the slide rail 2 may be supported by the support units 1 .

[0025] The connection method between the base body 4 and the building body 3 can be selected from existing connection methods, which will not be described in detail here.

[0026] The sliding portion 5 is inserted into the sliding hole, so that the sliding portion 5 can move relative to the seat body 4 .

[0027] The first support portion 6 , the second support portion 8 , the seat body 4 and the sliding portion 5 form a triangular structure, so that the first support portion 6 and the second support portion 8 can stably support the rail support portion 7 .

[0028] The first support portion 6 is relative to the rotation axis of the sliding portion 5, the second support portion 8 is relative to the rotation axis of the seat body 4, and the first support portion 6 and the second support portion 8 are relative to the rotation axis of the track support portion 7 can be parallel. For example, the rotation axis can be parallel to the horizontal direction, so that the position of the track support portion 7 in the vertical direction can be adjusted.

[0029] The slide rail 2 is used for sliding the steel structure, and the steel structure can be directly connected to the slide rail 2 by sliding. Alternatively, the slide rail 2 can also be provided with a supporting structure so that the steel structure can be connected to the slide rail 2 by sliding.

[0030] By adjusting the position of the sliding part 5 relative to the seat body 4, the inner angle of the triangular structure formed by the first support part 6, the second support part 8, the seat body 4 and the sliding part 5 can be adjusted, and the distance between the connection between the first support part 6 and the second support part 8 relative to the seat body 4 can be changed, thereby allowing the support unit 1 to adjust the support height of the slide rail 2.

[0031] See also Figure 1 In some embodiments, the support unit 1 also includes a driving part 11, which is rotatably connected to the seat body 4, and the rotation axis of the driving part 11 is parallel to the extension direction of the sliding hole. Along the rotation axis of the driving part 11, the driving part 11 is provided with a threaded through hole, and the sliding part 5 is penetrated through the threaded through hole and threadedly connected with the threaded through hole.

[0032] The rotational connection method between the driving part 11 and the seat body 4 can be selected from existing connection methods, which will not be described here.

[0033] The driving part 11 is used to drive the sliding part 5 to move along the seat body 4. Specifically, the driving part 11 is rotated. Since the driving part 11 and the sliding part 5 are threadedly connected, the sliding part 5 can move along the sliding hole under the action of the thread.

[0034] See also Figure 2 In some embodiments, the driving part 11 is a gear structure, and the supporting unit 1 further includes a driving gear 10, which is rotatably connected to the seat body 4, and the driving gear 10 is meshed with the driving part 11, and the radius of the driving gear 10 is smaller than the radius of the driving part 11.

[0035] The driving gear 10 is meshed with the driving portion 11 , so that when the driving gear 10 rotates, the driving portion 11 can rotate under the action of the driving gear 10 .

[0036] The radius of the driving gear 10 is smaller than the radius of the driving portion 11 , so that the driving gear 10 can drive the driving portion 11 to rotate with less effort.

[0037] See also Figure 1 In some embodiments, the support unit 1 further includes a reducer 9 , and an output end of the reducer 9 is transmission-connected to the driving gear 10 .

[0038] The reducer 9 facilitates adjusting the torque of the external driving structure transmitted to the driving gear 10. For example, the driving gear 10 can be driven to rotate by a motor, that is, the output end of the motor is connected to the input end of the reducer 9, and the output end of the reducer 9 is connected to the driving gear 10.

[0039] The structure and working principle of the reducer 9 are well known to those skilled in the art and will not be described in detail here.

[0040] See also Figure 1 and Figure 3 In some embodiments, along the extension direction of the sliding hole, the sliding portion 5 includes a first end and a second end located on both sides of the seat body 4, the first support portion 6 is rotatably connected to the first end, and the second end is provided with a limiting boss 13, and the sliding portion 5 is detachably provided with a plurality of abutment blocks 12, and the abutment blocks 12 are arranged on the side of the limiting boss 13 facing the seat body 4.

[0041] The limiting boss 13 is used to limit the movement of the abutment block 12 along the sliding part 5 in the direction away from the seat body 4. The abutment block 12 cooperates with the limiting boss 13 to limit the movement of the sliding part 5 toward the first end, that is, when the sliding part 5 moves toward the first end, the abutment block 12 can abut against the seat body 4, so that the sliding part 5 cannot move, reducing the risk of displacement after the sliding part 5 moves to the specified position.

[0042] There are multiple abutment blocks 12, and the abutment blocks 12 are detachably connected to the sliding part 5, so that the limiting effect of the abutment blocks 12 on the sliding part 5 can be adjusted according to the position of the sliding part 5 relative to the seat body 4. When the distance between the second end of the sliding part 5 and the seat body 4 increases, the number of abutment blocks 12 can be increased. Conversely, when the distance between the second end of the sliding part 5 and the seat body 4 decreases, the number of abutment blocks 12 can be reduced.

[0043] See also Figure 4 In some embodiments, the abutment block 12 is a ring-shaped structure with a notch, and the abutment block 12 is sleeved on the sliding part 5 .

[0044] The notch of the abutting portion enables the abutting portion to be sleeved on the sliding portion 5 or removed from the sliding portion 5, thereby achieving the purpose of detachable connection between the abutting portion and the sliding portion 5.

[0045] See also Figure 3 In some embodiments, the sliding portion 5 includes a frustum segment 14, the small diameter end of the frustum segment 14 faces the seat body 4, the limiting boss 13 is an annular structure, the inner circumferential wall of the limiting boss 13 is a frustum through hole adapted to the frustum segment 14, and the limiting boss 13 is sleeved on the frustum segment 14.

[0046] In this embodiment, the limiting boss 13 may include a first half ring and a second half ring. The first half ring and the second half ring are closed so that the limiting boss 13 can be sleeved on the frustum section 14 .

[0047] The cooperation between the frustum section 14 and the limiting boss 13 reduces the risk of displacement of the limiting boss 13 relative to the sliding portion 5 , which causes the limiting function of the abutment block 12 to fail.

[0048] In some embodiments, along the sliding extension direction, the sliding portion 5 is provided with a plurality of frustum segments 14 at intervals.

[0049] There are multiple frustum sections 14 , so that the position of the limiting boss 13 relative to the sliding part 5 can be adjusted as needed, thereby increasing the adaptability of the limiting boss 13 and the abutting block 12 to the working state of the sliding part 5 .

[0050] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made by ordinary technicians in this field to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
