[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the present invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

However, it is understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

It is understood that "first, second, third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this utility model described herein can be implemented in an order other than that illustrated or described herein.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to limit the invention.

[0021] The following detailed description is provided with reference to specific embodiments. It should be noted that the sequence numbers of the following embodiments are not intended to limit the preferred order of the embodiments. This utility model provides a bridge-building machine. Figure 1 This is a schematic diagram of an embodiment of the mobile frame for the bridge-building machine provided by this utility model. Figure 2 This is an enlarged schematic diagram of one embodiment of the first side beam provided by this utility model; the bridge building machine provided by this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figure 1 The bridge-building machine mobile frame provided by this utility model includes a first crossbeam 10, a first side beam 20, and a second side beam 30. The two ends of the first crossbeam 10 are connected to the first side beam 20 and the second side beam 30, respectively. The first crossbeam 10 spans across the bridge, while the first side beam 20 and the second side beam 30 are located on opposite left and right sides of the bridge, forming an inverted U-shaped structure. For the bridge-building machine mobile frame provided by this utility model, the first side beam 20 and / or the second side beam 30 are L-shaped structures, including longitudinal and transverse fixed beams. That is, when the first side beam 20 is L-shaped, it includes both longitudinal and transverse fixed beams; when the second side beam 30 is L-shaped, it includes both longitudinal and transverse fixed beams. The transverse fixing beam is set parallel to the first transverse beam 10. The transverse fixing beam is located under the bridge. After the bridge construction machine moves the frame to the preset position, the transverse fixing beam is fixed to the bottom of the bridge.

[0023] The bridge-building machine mobile frame provided by this utility model also includes a longitudinal side formwork cylinder 40. This longitudinal side formwork cylinder can be combined with the hydraulic system and intelligent auxiliary system of the bridge-building machine to ensure accurate positioning and fastening of the formwork during bridge construction, providing good forming conditions for concrete pouring. The longitudinal side formwork cylinder 40 provided by this utility model moves vertically up and down to achieve its support function. However, in actual bridge-building scenarios, the vertical displacement distance of the longitudinal side formwork cylinder 40 is limited, making it unsuitable for many bridge-building scenarios. The bridge-building machine mobile frame provided by this utility model increases the vertical displacement distance of the longitudinal side formwork cylinder by completely installing the longitudinal side formwork cylinder 40 in the transverse fixed beam, with the bottom of the longitudinal side formwork cylinder 40 extending beyond the transverse fixed beam, thus making it suitable for more bridge-building scenarios. Specifically, taking the first side beam 20 as an example, a longitudinal side formwork cylinder mounting groove is formed on the transverse fixed beam 202 of the first side beam 20, and the longitudinal side formwork cylinder mounting groove is usually a through hole penetrating the transverse fixed beam 202. The longitudinal side formwork cylinder 40 is longitudinally installed in the longitudinal side formwork cylinder mounting groove. The top of the longitudinal side formwork cylinder 40 protrudes from the upper surface of the transverse fixed beam, and the bottom of the longitudinal side formwork cylinder 40 also extends beyond the bottom of the transverse fixed beam; that is, the height of the longitudinal side formwork cylinder 40 is greater than the thickness of the transverse fixed beam. This configuration allows for further adjustment of the vertical movement distance of the longitudinal side formwork cylinder 40 by adjusting the height of the bottom of the longitudinal side formwork cylinder 40 extending beyond the transverse fixed beam 202, making it suitable for more bridge construction scenarios.

[0024] Please refer to Figure 2 The longitudinal side mold cylinder 40 includes a first cylinder support body 401 and a limiting structure. The first cylinder support body 401 is the main structure providing support, and it is completely embedded in the longitudinal side mold cylinder mounting groove, with its bottom extending beyond the bottom of the groove. The height of the first cylinder support body 401 extending beyond the groove can be adjusted to change the distance between its top and the bridge. Furthermore, the first cylinder support body 401 can be designed as a telescopic structure, allowing the longitudinal side mold cylinder to be used in multiple bridge construction scenarios where the distance between the cylinder and the bridge bottom is small or large. To ensure the cylinder does not move during support and affect the support effect, the limiting structure is used to limit the first cylinder support body 401. Figure 2As shown, the limiting structure includes a limiting plate 402, which is disposed on the side surface of the transverse fixed beam 202 near the first crossbeam 10. An inner barb structure is formed on the side of the limiting plate 402 near the transverse fixed beam, which can be used to fix the limiting plate 402 to the transverse fixed beam 202. A limiting hole is also formed on the limiting plate 402 at a position corresponding to the first hydraulic cylinder support body 401, through which the first hydraulic cylinder support body 401 passes. The limiting structure also includes a limiting nut 403, which is disposed on the limiting plate 402 at a position corresponding to the limiting hole. The limiting nut 403 can fix the first hydraulic cylinder support body 401, ensuring that the first hydraulic cylinder support body 401 will not shift. When it is necessary to adjust the distance between the top of the first cylinder support body 401 and the bridge, the limit nut 403 can be loosened to control the first cylinder support body 401 to move in the vertical direction, and then the limit nut 403 can be tightened to limit the first cylinder support body.

[0025] Please refer to Figure 2 ,exist Figure 2 In this design, the top of the first hydraulic cylinder support body 401 includes a contact surface 4011, which can directly contact the bridge to support it. The area of ​​the contact surface 4011 can be set according to actual needs. Generally speaking, the larger the area of ​​the contact surface 4011, the better the support effect on the bridge. In some embodiments, there can be multiple longitudinal side mold hydraulic cylinders 40, and the multiple longitudinal side mold hydraulic cylinders 40 are arrayed and distributed on the transverse fixed beam. Figure 2 In the illustrated embodiment, there are two longitudinal side mold cylinders, arranged in an array on the same transverse fixed beam. In other embodiments, if both the first side beam 20 and the second side beam 30 include transverse fixed beams, each of the transverse fixed beams of the first side beam 20 and the second side beam 30 may include one or more longitudinal side mold cylinders; the number of longitudinal side mold cylinders on different side beams may be the same or different.

[0026] Please refer to Figure 3 , Figure 3 This is a top view schematic diagram of another embodiment of the first side beam provided by this utility model. Figure 3In the illustrated embodiment, the bridge-building machine's moving frame also includes a transverse side formwork cylinder 50. A transverse side formwork cylinder mounting groove is formed on the transverse fixed beam 202, opening towards the direction close to the first crossbeam 201. Unlike the longitudinal side formwork cylinder mounting groove, the bottom of the transverse side formwork cylinder mounting groove does not extend beyond the bottom of the transverse fixed beam 202; that is, the depth of the transverse side formwork cylinder mounting groove is less than the thickness of the transverse fixed beam 202. The transverse side formwork cylinder 50 is installed transversely in the transverse side formwork cylinder mounting groove, and can move within the groove in a direction parallel to the first crossbeam 10. Specifically, since the longitudinal side formwork cylinder 40 moves vertically, the longitudinal side formwork cylinder mounting groove needs to completely penetrate the transverse fixed beam in the vertical direction; while the transverse side formwork cylinder 50 moves horizontally, therefore the transverse side formwork cylinder mounting groove does not need to completely penetrate the transverse fixed beam in the vertical direction, and the transverse fixed beam itself can be used to support the transverse side formwork cylinder 50.

[0027] Please refer to Figure 3 The transverse side mold cylinder 50 provided by this utility model includes a second cylinder support body 501 and a locking structure 502. The second cylinder support body 501 is transversely arranged in the transverse side mold cylinder mounting groove, and the locking structure 502 is perpendicularly arranged to the transverse side mold cylinder mounting groove, with a portion of the locking structure 502 embedded in the transverse side mold cylinder mounting groove. A locking through hole is formed on the portion of the locking structure 502 embedded in the transverse side mold cylinder mounting groove, through which the second cylinder support body 501 passes and is transversely fixed in the transverse side mold cylinder mounting groove. The second cylinder support body 501 is a telescopic structure. After the second cylinder support body 501 extends or retracts, the locking structure 502 can fix the position of the second cylinder support body after extension or retraction to avoid displacement during subsequent bridge construction that would affect the bridge construction accuracy. One end of the second cylinder support body 501 contacts the longitudinal side mold cylinder 40 closest to the second cylinder support body 501 to push the longitudinal side mold cylinder 40 to move horizontally. Specifically, the longitudinal side mold cylinder 40 in this invention can adjust the distance between its top and the bridge by changing the height of its bottom extending beyond the transverse fixed beam 202. Meanwhile, the transverse side mold cylinder 50 can be used to control the displacement of the longitudinal side mold cylinder 40 along the extension direction of the transverse fixed beam 202 in the horizontal direction, thereby changing the contact position between the longitudinal side mold cylinder 40 and the bridge. This arrangement allows the longitudinal side mold cylinder 40 to move both vertically and horizontally, enabling adjustment of its position in actual bridge construction scenarios to better assist the bridge construction process. Typically, the top of the second cylinder support body 501 does not exceed the top of the transverse fixed beam 202, meaning the second cylinder support body 501 is completely fixed inside the transverse side mold cylinder mounting groove.

[0028] Please refer to Figure 4 This is a schematic diagram of another embodiment of the first side beam provided by this utility model. The bridge-building machine mobile frame provided by this utility model also includes a reinforcing beam 60, the two ends of which are fixedly connected to a transverse fixed beam and a longitudinal fixed beam, respectively. Therefore, the reinforcing beam is usually fixed obliquely on the first side beam 20 and / or the second side beam 30. In some embodiments, there can be multiple reinforcing beams, each with a different length, and these multiple reinforcing beams can be obliquely and parallelly arranged on the first side beam 20 or the second side beam 30. When the reinforcing beams are respectively arranged on the first side beam and the second side beam, there can be multiple reinforcing beams, including a first reinforcing beam and a second reinforcing beam. The first reinforcing beam is obliquely and parallelly arranged on the first side beam 20, and the second reinforcing beam is obliquely and parallelly arranged on the second side beam 30. By setting multiple reinforcing beams fixedly connected to the first side beam 20 and the second side beam 30, the stability of the first side beam 20 and the second side beam 30 can be enhanced, thereby enhancing the stability of the entire bridge-building machine mobile frame.

[0029] Please refer to Figures 1-4 For the bridge-building machine mobile frame provided by this utility model, the first side beam 20 and the second side beam 30 are generally L-shaped structures. Both the first side beam 20 and the second side beam 30 include longitudinal fixed beams and transverse fixed beams; and there are multiple longitudinal side mold cylinders 40, which are evenly distributed on the transverse fixed beams of the first side beam 20 and the second side beam 30. Figure 1 Taking the illustrated embodiment as an example, two longitudinal side mold cylinders 40 can be installed on the transverse fixed beam of the first side beam 20. Similarly, two longitudinal side mold cylinders 40 can also be installed on the transverse fixed beam of the second side beam 30. However, only one transverse side mold cylinder 50 can be installed on a single transverse fixed beam, and the movement of multiple longitudinal side mold cylinders 40 can be controlled simultaneously using one transverse side mold cylinder 50.

[0030] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
