The end bridge section needs to be lifted at a certain angle or straightened. Therefore, it is necessary to study a bridge section straightening mechanism to quickly realize the lifting and straightening of the end bridge section. Summary of the Invention

[0003] This invention provides a bridge section straightening mechanism that can quickly lift and straighten the end bridge section.

[0009] The pin is inserted into the double-ear support ear hole provided on the upper part of the end bridge section. The handle structure is pulled outward. The pin is removed from the support ear hole. After the third hole structure on the upper part of the guide plate structure is aligned with the support ear hole, the handle structure is released.

[0010] The pin is inserted into the support lug hole by the force of the position return structure, and the third hole structure on the upper part of the guide plate structure is hinged to the double lug seat on the upper part of the end bridge section through the pin.

[0011] Furthermore, the second and third hole structures adopt an oval hole structure.

[0024] The figure shows a bridge section straightening mechanism, including: a straightening cylinder 1, a cylinder shaft 2, a guide plate structure 3, a connecting shaft 4, a plate seat pin 5, and a pin assembly 6;

[0025] The straightening cylinder 1 includes a cylinder end and a rod end; the guide plate structure 3 includes a first hole structure, a second hole structure, and a third hole structure. The second hole structure and the third hole structure are oval hole structures.

[0026] In this embodiment of the invention, the cylinder end of the hydraulic cylinder is connected to the middle box of the straightening bridge section via the hydraulic cylinder shaft 2, and the rod end of the hydraulic cylinder is connected to the first hole structure on the upper part of the guide plate structure 3 via the connecting shaft 4; the lower part of the guide plate structure 3 is connected to the straightening bridge section via the plate seat pin 5.

[0027] The pin assembly 6 is fixed to the side of the double-ear seat on the upper part of the end bridge section. The straightening bridge section and the bottom of the end bridge section are hinged together by a joint. When the straightening cylinder retracts, the end bridge section rotates counterclockwise around the bottom connection point. When the straightening cylinder retracts to the first length, the end bridge section is lifted to the first angle. When the straightening cylinder retracts to the limit position, the end bridge section is lifted to the limit position. When the straightening cylinder extends, the end bridge section rotates clockwise around the bottom connection point. When the straightening cylinder extends to the second length, the end bridge section unfolds to the second angle. When the straightening cylinder extends to the limit position, the end bridge section is fully straightened, and the end bridge section is straightened.

[0028] In this embodiment of the invention, the pin assembly 6 includes: a sleeve 7, a pin 8, a return spring 9, and a handle structure 10.

[0029] It is understood that in other embodiments of the present invention, the return spring 9 may also adopt other forms of position return structure, and the specific structure is not specifically limited here.

[0030] The pin 8 is inserted into the ear hole of the double-eared support provided on the upper part of the end bridge section. The handle structure 10 is pulled outward, and the pin 8 is removed from the ear hole. After the third hole structure on the upper part of the guide plate structure 3 is aligned with the ear hole, the handle structure 10 is released. The pin 8 is inserted into the ear hole by the force of the return spring 9. The third hole structure on the upper part of the guide plate structure 3 is hinged to the double-eared support on the upper part of the end bridge section through the pin.

[0031] In this embodiment of the invention, a double-ear seat structure is provided at the bottom of the middle box of the straightening bridge section, and the cylinder end of the hydraulic cylinder is hinged to the middle box of the straightening bridge section through the hydraulic cylinder shaft.

[0032] The guide plate structure is provided with the second hole structure at the lower part, and the guide plate structure is hinged to the straight bridge section through the plate seat pin.

[0033] In another embodiment of the present invention, a bridge section straightening mechanism is provided. The cylinder end of the straightening cylinder 1 is hinged to a double-ear seat at the bottom of the middle box of the straightening bridge section via a cylinder shaft 2. The rod end is hinged to the first hole structure on the upper part of the guide plate structure 3 via a connecting shaft 4. The lower part of the guide plate structure 3 is hinged to a guide plate seat at the lower part of the straightening bridge section via a plate seat pin 5. The second hole structure and the third hole structure of the guide plate structure 3 are both oval holes.

[0034] The pin assembly 6 consists of a sleeve 7, a pin 8, a return spring 9, and a handle structure 10. The pin assembly 6 is fixed to the side of the double-ear seat on the upper part of the end bridge section by bolts. In the normal state, the pin 8 in the pin assembly 6 is inserted into the bearing ear hole. Pulling the handle structure 10 of the pin assembly 6 to the right moves the pin 8 out of the bearing ear hole. After the third hole structure on the upper part of the guide plate structure 3 is aligned with the bearing ear hole, the handle structure 10 is released. The pin 8 moves to the left and inserts into the bearing ear hole by the elastic force of the return spring 9. The third hole structure on the upper part of the guide plate structure 3 is then hinged to the double-ear seat on the upper part of the end bridge section through the pin 8.

[0035] The extension bridge section and the end bridge section are hinged at the bottom via a joint. When the extension cylinder 1 retracts, the end bridge section rotates counterclockwise around the bottom hinge point under the action of the extension cylinder 1. When the extension cylinder 1 retracts a certain length, the end bridge section is lifted to a certain angle. When the extension cylinder 1 retracts to its limit position, the end bridge section is lifted to its limit position. Conversely, when the extension cylinder 1 extends, the end bridge section rotates clockwise around the bottom hinge point. When the extension cylinder 1 extends a certain length, the end bridge section unfolds to a certain angle. When the extension cylinder 1 extends to its limit position, the end bridge section is fully straightened, thus straightening the end bridge section.

[0036] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
