[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 and Figure 2 The utility model provides a technical solution: an extendable support bracket, comprising a support sleeve 1 and a lifting stud 4, a pad 2 is fixed to the bottom of the support sleeve 1, a drive cover 3 is installed on the top of the support sleeve 1, the middle of the drive cover 3 is penetrated and connected with the lifting stud 4, and a bracket 5 is arranged on the upper end of the lifting stud 4; sliding sleeves 7 are symmetrically welded on both sides of the top of the pad 2, a guide rod 8 is arranged between the two groups of the pads 2, and the guide rod 8 is penetrated and connected with the sliding sleeve 7.

[0024] During specific implementation, two support brackets of the same specification are symmetrically placed together, and the sliding sleeves 7 on the two sets of pads 2 are connected through the guide rods 8, so that the two support brackets can be placed side by side for use.

[0025] See also Figure 1 and Figure 2 A threaded sleeve 9 is vertically welded to the circumferential surface of the support sleeve 1 , and a bidirectional screw 10 is connected to two adjacent threaded sleeves 9 , and a rotating disk is fixed in the middle of the bidirectional screw 10 .

[0026] During specific implementation, the bidirectional screw 10 is driven to perform forward or reverse motion by operating the rotating disk to rotate forward or reversely, so that the bidirectional screw 10 can perform forward or reverse thread transmission with the threaded sleeve 9, so that the two ends of the bidirectional screw 10 drive the two groups of threaded sleeves 9 to move closer to or away from each other, so that the two groups of support sleeves 1 and the pads 2 slide along the parallel guide rods 8, ensuring that the brackets 5 on the top of the two groups of support sleeves 1 are moved closer to or away from each other, and then different distances of support can be achieved for the buildings of roads and bridges, which can have the effect of extending the support position.

[0027] See also Figure 1-Figure 3A damper 401 for vibration buffering is embedded in the upper end of the lifting stud 4, and blocks 6 are symmetrically arranged at the bottom of the bracket 5. A U-shaped opening is arranged between the two blocks 6, and the U-shaped opening between the two blocks 6 is clamped with the top of the lifting stud 4. The U-shaped opening between the two blocks 6 is clamped on the top of the lifting stud 4, which can facilitate the positioning and installation of the bracket 5 and prevent the bracket 5 from being offset during installation, and the bottom of the U-shaped opening is fixed to the damper 401.

[0028] In a specific implementation, when the bracket 5 is supported on the bottom surface of a road bridge building, the damper 401 installed between the bracket 5 and the lifting stud 4 ensures that the supporting bracket has a seismic buffering effect.

[0029] See also Figure 1 , Figure 3 and Figure 4 The upper and lower surfaces of the driving cover 3 are plugged with the lifting stud 4 through a through hole. The inner wall of the through hole of the driving cover 3 is provided with a bearing sleeve 301. A gear ring 302 is connected to the bearing sleeve 301. The bearing sleeve 301 can assist the gear ring 302 in rotating to prevent the gear ring 302 from deviating and shaking. The inner wall of the gear ring 302 is provided with a thread, and the gear ring 302 is threadedly connected to the lifting stud 4;

[0030] The outer side of the gear ring 302 is meshed with a driving gear 304 . The driving gear 304 is connected to the output shaft of a driving motor 305 . The driving motor 305 is installed on the lower surface of the driving cover 3 .

[0031] During specific implementation, the driving motor 305 on the lower side of the driving cover 3 is started to drive the driving gear 304 to rotate forward and reverse, so that the driving gear 304 and the gear ring 302 are meshed and transmitted, so that the gear ring 302 is reversed or rotated forward. When the gear ring 302 is reversed or rotated forward, the inner thread can be used to perform reverse or forward thread transmission with the lifting stud 4.

[0032] See also Figure 3 Two sides of the cross section of the lifting stud 4 are horizontal plane structures, and the other two sides of the cross section of the lifting stud 4 are arc-shaped structures. A slide groove 402 is longitudinally opened on the horizontal side of the lifting stud 4, and guide blocks 303 docking with the slide groove 402 are welded on the upper and lower sides of the driving cover 3.

[0033] During specific implementation, due to the sliding of the sliding grooves 402 on both sides of the lifting stud 4 and the guide block 303, when the gear ring 302 is reversed or rotated forward, the lifting stud 4 can be driven to be lifted and lowered along the support sleeve 1 and the drive cover 3, and the lifting stud 4 has the effect of preventing deflection and rotation when sliding along the guide block 303.

[0034] To sum up, the two support brackets are placed side by side for use, and the drive motor 305 is started to drive the drive gear 304 to rotate forward and reverse, so that the thread inside the gear ring 302 and the lifting stud 4 are threadedly transmitted, thereby ensuring that the support bracket can drive the bracket 5 to support the road bridge building through the lifting stud 4 when rising, ensuring that the road bridge building has a stable placement effect.
