[0028] Reference Figure 1-3 The figure shows a preferred embodiment of the present invention.

[0029] A supporting and stable self-erecting bridge used for road construction has a bridge body erected and arranged along the extension direction of the road. The road has a construction section 201 and erection sections 200 formed at both ends of the construction section 201; the bridge body is arranged above the construction section 201, and both ends of the bridge body are respectively abutted on the erection sections 200; the top of the bridge body forms a continuous erection road surface for vehicles to travel, and the bridge body and the construction section 201 enclose a construction space 301 for workers to work.

[0030] The bridge body has a middle section 300 horizontally arranged above the construction section 201. A plurality of middle hydraulic rods 302 are provided at the bottom of the middle section 300. The bottom of the middle hydraulic rods 302 is pressed against the construction section 201, and the top of the middle hydraulic rods 302 is in contact with the bottom of the middle section 300. The middle hydraulic rods 302 support the middle section 300 from bottom to top.

[0031] The top of the intermediate hydraulic rod 302 has an intermediate abutting end that abuts against the bottom of the intermediate section 300. The middle part of the intermediate hydraulic rod 302 is provided with multiple swinging plates 400 that swing up and down. The multiple swinging plates 400 are arranged circumferentially around the intermediate hydraulic rod 302; the inner end of the swinging plate 400 is hingedly arranged, and the outer end of the swinging plate 400 is extended outward away from the intermediate hydraulic rod 302. The swinging plate 400 has an upwardly arranged support surface, which abuts against the bottom of the intermediate section 300 from bottom to top.

[0032] Each swing plate 400 is connected to a tilting hydraulic rod 304 that supports the swing plate 400, and the tilting hydraulic rod 304 limits the swing plate 400 from swinging downward; each swing plate 400 is provided with a pressure sensor that detects the pressure applied by the middle section 300 on the swing plate 400, and multiple pressure sensors and multiple tilting hydraulic rods 304 are respectively connected to a controller, which controls the supporting force of the tilting hydraulic rod 304 supporting the swing plate 400 according to the pressure value of the pressure sensor.

[0033] The above-mentioned supporting stable self-erecting bridge for road construction is constructed such that the bridge body is erected on the construction section 201, and the middle section 300 is supported by the middle hydraulic rod 302. The two ends of the bridge body are abutted on the erection section 200, and the entire bridge body is relatively fixed above the construction section 201. The erected road surface replaces the construction section 201, and vehicles can travel normally on the road through the erected road surface without affecting the normal use of the road. The construction is convenient and will not cause road congestion. At the same time, workers can carry out normal construction work in the construction space 301.

[0034] By arranging multiple swing plates 400 on the middle hydraulic rod 302, the pressure value of each swing plate 400 can be detected by a pressure sensor. By adjusting the supporting force of the swing plate 400 by tilting the hydraulic rod 304, the middle hydraulic rod 302 can support the middle section 300 more stably, and the entire bridge body is in a stable and balanced state.

[0035] The middle part of the intermediate hydraulic rod 302 has an upwardly arranged annular step, on which a collar 303 is sleeved, and the bottom of the collar 303 presses against the annular step from top to bottom; the inner end of the swing plate 400 is hinged on the collar 303, and the tilting hydraulic rod 304 is connected to the collar 303.

[0036] In this way, the collar 303 can be assembled on the middle hydraulic rod 302 , which is convenient for installation and facilitates the arrangement of the swing plate 400 .

[0037] The inner end of the swing plate 400 is hinged to the top of the collar 303, and the inner end of the swing plate 400 presses against the top of the collar 303 from top to bottom. When the swing plate 400 is subjected to the downward pressure of the middle section 300, the inner end of the swing plate 400 presses against the collar 303 from top to bottom, preventing the inner end of the swing plate 400 from falling off the collar 303, ensuring that the swing plate 400 better supports the middle section 300.

[0038] The top of the ring 303 has a downwardly concave mounting groove, and the inner end of the swing plate 400 is embedded in the mounting groove; a hinge shaft is provided in the mounting groove, and the hinge shaft is rotatably connected to both sides of the inner end of the swing plate 400, and the inner end of the swing plate 400 is pressed against the bottom of the mounting groove from top to bottom.

[0039] The inner end of the swing plate 400 is embedded in the mounting groove, which not only facilitates the hinge between the swing plate 400 and the collar 303 , but also the mounting groove can limit the position of the inner end of the swing plate 400 , so that the swing plate 400 can more stably support the middle section 300 .

[0040] In this embodiment, the swing plate 400 includes a swing section 402 and a support section 401. The swing section 402 and the support section 401 are arranged in a bent manner. The inner end of the swing section 402 is hinged to the ring 303, and the inner end of the support section 401 is connected to the outer end of the swing section 402. The outer end of the support section 401 is extended outward away from the intermediate hydraulic rod 302; the support surface is formed at the top of the support section 401.

[0041] The supporting sections 401 of the multiple swing plates 400 support the middle section 300 from bottom to top in a lifting shape, and cooperate with the middle abutment end of the middle hydraulic rod 302 to form a multi-position abutment on the middle section 300. The swing plates 400 can adjust the supporting force according to the changes in the pressure value they bear, thereby supporting the middle section 300 more stably and balancedly, avoiding the occurrence of bridge body tilting and other phenomena.

[0042] The lower end of the tilting hydraulic rod 304 is connected to the collar 303 , and the upper end of the tilting hydraulic rod 304 is butted against the bottom of the swing section 402 , tilting and supporting the swing section 402 from top to bottom.

[0043] The middle portion of the intermediate abutting end is recessed downward to form a docking groove 600. The bottom of the intermediate section 300 protrudes downward to form a docking block 500. The docking block 500 is inserted into the docking groove 600, with the outer wall of the docking block 500 abutting the inner wall of the docking groove 600. In this way, the abutting engagement between the intermediate abutting end and the intermediate section 300 is automatically aligned and adjusted by the automatic abutment between the docking groove 600 and the docking block 500, thus avoiding unbalanced support.

[0044] In this embodiment, the bottom of the docking groove 600 is recessed downward to form a lower hollow groove 601, and the bottom of the docking block 500 is recessed upward to form an upper hollow groove 501. The upper hollow groove 501 and the lower hollow groove 601 are aligned up and down; an elastic column 700 is inserted in the upper hollow groove 501, and the upper part of the elastic column 700 is inserted into the upper hollow groove 501, and the lower part of the elastic column 700 is inserted into the lower hollow groove 601. When the outer wall of the docking block 500 is docked on the inner wall of the docking groove 600, the elastic column 700 is in a compressed state in the upper hollow groove 501 and the lower hollow groove 601, respectively.

[0045] By arranging the elastic column 700 to be inserted into the upper hollow groove 501 and the lower hollow groove 601, the alignment arrangement of the docking groove 600 and the middle part of the docking block 500 is automatically adjusted, thereby achieving the support balance between the middle abutting end and the middle section 300. In addition, the elastic column 700 can be elastically deformed. When abutment imbalance occurs, the abutment balance adjustment can be achieved by adjusting the outer wall of the docking block 500 and the inner wall of the docking groove 600.

[0046] An internal hollow column 701 is provided within the elastic column 700. The internal hollow column 701 extends axially along the elastic column 700. When the elastic column 700 is compressed in the upper hollow groove 501 and the lower hollow groove 601, the elastic column 700 is squeezed toward the internal hollow column 701. The provision of the internal hollow column 701 enables compression deformation of the elastic column 700 in the upper hollow groove 501 and the lower hollow groove 601.

[0047] An inclined section 100 is provided at both ends of the middle section 300, extending downward along the end of the middle section 300 toward the direction of the road, and the inclined section 100 is arranged downwardly away from the middle section 300; the upper end of the inclined section 100 is docked with the end of the middle section 300, and the lower end of the inclined section 100 is abutted on the erection section 200, forming a relatively fixed integrated structure between the two inclined sections 100 and the middle section 300.

[0048] The top of the middle section 300 and the tops of the two inclined sections 100 form the erected road surface, and the bottom of the middle section 300 and the bottoms of the two inclined sections 100 enclose a construction space 301; the upper end of the inclined section 100 forms a docking section, which is docked at the end of the middle section 300, and the bottom of the docking section supports an end hydraulic rod 102, which supports the inclined section 100 from bottom to top.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
