[0055] Example Two

[0056] This embodiment provides a construction device for assembling a prefabricated emergency repair pier, which is used to assemble the prefabricated emergency repair pier in Embodiment One.

[0057] Please refer to Figures 2 - 5 , the construction device of the prefabricated emergency repair pier includes a fence 10 and a support plate 20. The fence 10 surrounds the support plate 20 on all sides. The bottom pier 1, the standard pier 2, the top pier 3 and the cross beam 5 are sequentially placed on the support plate 20 and then further assembled. The fence 10 plays a maintenance role to prevent the bottom pier 1, the standard pier 2 and the top pier 3 from falling.

[0058] Optionally, the support plate 20 has a folding structure. The folding line overlaps with the axis of the support plate 20 and is parallel to its length direction. The fence 10 includes a separated first part and a second part. Both the first part and the second part are in a semi-surrounding structure, and the first part and the second part are symmetrical about the folding line. Folding the support plate 20 along its folding line reduces the overall volume and is convenient for transportation.

[0059] The support plate 20 is provided with mounting holes 201. The aperture of the mounting holes 201 is larger than the maximum cross-sectional dimensions of the foundation 100, the bottom pier 1, the standard pier 2 and the top pier 3. The support plate 20 is sleeved and locked to the foundation 100 through the mounting holes 201. The bottom pier 1 is hoisted and placed on the support plate 20. After the assembly of the bottom pier 1 is completed, the support plate 20 is lifted. The support plate 20 is sleeved and locked to the bottom pier 1 through the mounting holes 201. Repeat the above steps to sequentially splice the standard pier 2 and the top pier 3.

[0060] Furthermore, the construction device of the prefabricated emergency repair pier further includes a sliding assembly 30. The sliding assembly 30 is used to sequentially move the bottom pier 1, the standard pier 2 and the top pier 3 placed on the support plate 20 to the mounting holes 201 for positioning and installation.

[0061] The sliding assembly 30 includes two sliding units installed on the top of the support plate 20. The mounting holes 201 are located between the two sliding units. The bottom pier 1, the standard pier 2 and the top pier 3 are sequentially placed on the two sliding units, and the two sliding units move them to the mounting holes 201.

[0062] The sliding unit includes a support 301, guide rails, transmission gears, a driving member, and a transmission plate 302. The support 301 is installed on the top of the support plate 20. A communication groove is formed in the top of the support 301 along its length direction. There are two guide rails, which are installed on the top of the support 301 at intervals, and the guide rails are arranged along the length direction of the support 301. Rack teeth are provided on one side of the two guide rails facing each other. The transmission plate 302 is slidably connected to the two guide rails. The transmission gears are engaged with the two rack teeth. One end of the transmission gear in the axial direction extends and is connected to the transmission plate 302, and the other end of the transmission gear in the axial direction extends into the communication groove and is connected to the output end of the driving member. The driving member drives the transmission gear to rotate self - axially. The transmission gear is successively engaged with different teeth on the two rack teeth, driving the transmission plate 302 to slide along the two guide rails, and further moving the bottom pier 1, standard pier 2, or top pier 3 on the transmission plate 302.

[0063] Preferably, the two guide rails are symmetrically arranged along a folding line, and the guide rails are parallel to the folding line of the support plate 20 to improve the stability of movement.

[0064] Adaptively, a plurality of positioning grooves are circumferentially provided on the foundation 100, the first support sleeve, and the second support sleeve. The support plate 20 is self - locked in the positioning grooves. The positioning grooves are all located in the upper region of the foundation 100, the first support sleeve, and the second support sleeve, so as to shorten the distance between the positioning grooves and their top flange plates, ensuring that the heights of the parts of the foundation 100, bottom pier 1, and standard pier 2 extending out of the mounting hole 201 can all be less than the distance between the transmission plate 302 and the support plate 20, preventing the partial structures extending out of the mounting hole 201 from obstructing the movement of the bottom pier 1, standard pier 2, and top pier 3 by the transmission plate 302.

[0065] The construction device of the assembled emergency repair bridge pier further includes a jacking assembly 40. The jacking assembly 40 jacks up the bottom pier 1, standard pier 2, or top pier 3 at the mounting hole 201 to facilitate the reset of the sliding assembly 30, and the jacking assembly 40 lowers the bottom pier 1, standard pier 2, or top pier 3 at the mounting hole 201 to facilitate assembly.

[0066] The jacking assembly 40 includes a plurality of jacking members. The jacking members are installed on the top of the support plate 20. The plurality of jacking members are circumferentially arranged at intervals outside the mounting hole 201 for jacking up or lowering the bottom pier 1, standard pier 2, or top pier 3.

[0067] The construction device of the assembled emergency repair bridge pier further includes a locking assembly 50. The locking assembly 50 is used to lock the support plate 20 with the foundation 100, bottom pier 1, and standard pier 2.

[0068] The locking assembly 50 includes a plurality of locking units, which are circumferentially and spacedly installed along the edge of the mounting hole 201. In this embodiment, each locking unit includes two groups of pin shafts 501 and stoppers 502. The two pin shafts 501 are spacedly installed along the edge of the mounting hole 201, and the stopper 502 is correspondingly rotatably connected to the pin shaft 501. One end in the length direction of the stopper 502 is an arc surface, and one end in the length direction of the stopper 502 extends into the mounting hole 201. The foundation 100, the bottom pier 1 or the standard pier 2 extends into the mounting hole 201. One end in the length direction of the stopper 502 extends into the mounting hole 201 and is clamped in the corresponding positioning groove, and the other end in the length direction of the stopper 502 abuts against the upper end surface of the support plate 20 to achieve self-locking. When the support plate 20 is lifted, one end in the length direction of the stopper 502 with an arc surface slides out of the positioning groove, and the stopper 502 rotates clockwise along its corresponding pin shaft 501 to release the lock.

[0069] In other embodiments, each locking unit may include more than two groups of pin shafts 501 and stoppers 502, which are not specifically limited herein.

[0070] Optionally, the construction device of the assembled emergency repair bridge pier further includes a guiding assembly 60, which is used to restrict the sliding assembly 30 from moving to the bottom pier 1, the standard pier 2 or the top pier 3 of the mounting hole 201, and prevent the circumferential movement of the bottom pier 1, the standard pier 2 or the top pier 3 during the process of the lifting assembly 40 lowering the bottom pier 1, the standard pier 2 or the top pier 3, so as to ensure the uniqueness of the axial movement.

[0071] The guiding assembly 60 includes two guiding units installed along the edge of the mounting hole 201. The two guiding units are oppositely arranged along the radial direction of the mounting hole 201 to limit the circumferential movement of the bottom pier 1, the standard pier 2 or the top pier 3. Each guiding unit includes a guiding seat, a bearing and a guiding wheel 601. The guiding seat is installed along the edge of the mounting hole 201, the bearing is horizontally arranged on the guiding seat, and the guiding wheel 601 is rotatably connected to the bearing. Moreover, the heights of the two guiding wheels 601 are both higher than the heights of the parts of the foundation 100, the bottom pier 1 and the standard pier 2 extending out of the mounting hole, so as to ensure that the two guiding wheels 601 can abut against the first support sleeve of the bottom pier 1, the second support sleeve of the standard pier 2 and the third support sleeve of the top pier 3, thereby limiting their circumferential movement.

[0072] Preferably, the two guiding units are symmetrically arranged along the folding line of the support plate 20.
