[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides an anchoring device for a self-propelled bridge building machine, such as... Figure 1-4 As shown, the self-propelled bridge-building machine anchoring device includes: a frame 1, on which an anchoring mechanism 2 is provided; side arms 3 symmetrically arranged on both sides of the frame 1 with adjustable spacing; a base frame 4 mounted on the side arms 3 and capable of being raised and lowered, on which a horizontally adjustable assembly plate 5 is provided, and on which guide wheels 6 are provided; an assembly frame 8 mounted on the frame 1 with adjustable height, on which a rotating shaft 9 is rotatably mounted via bearings; traveling wheels 10 fixed on the rotating shaft 9; and a drive mechanism mounted on the assembly frame 8 for driving the rotating shaft 9 to rotate.

[0021] In this embodiment, during use, the spacing of the side arms 3 is first adjusted according to the width of the main bridge body, and then the height of the base frame 4 is adjusted so that the guide wheels 6 on the assembly plate 5 contact the side of the main bridge body. The rolling auxiliary device of the guide wheels 6 is used for initial positioning. Next, the height of the assembly frame 8 is adjusted so that the traveling wheels 10 contact the bridge surface or track. The drive mechanism is then started, and the drive mechanism drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the traveling wheels 10 to rotate, so that the entire device moves.

[0022] After moving to the designated position, the anchoring mechanism 2 is operated to fix the frame 1 to the main body of the bridge. Then, the height of the base frame 4 and the assembly frame 8 is adjusted to keep the guide wheel 6 and the traveling wheel 10 at a suitable distance from the main body of the bridge or the bridge deck to ensure that the device is stable.

[0023] The adjustability of the side arm 3, base frame 4, and assembly plate 5 enhances the adaptability of the device to bridges of different specifications. The cooperation between the traveling wheels 10 and the drive mechanism makes the device easier to move, helps reduce energy consumption during movement, and increases movement speed. The anchoring mechanism 2 works in conjunction with other adjustable components to improve the stability of the device after anchoring, ensure construction safety, and further improve construction efficiency. The anchoring mechanism 2 is the same as the existing technology, including a hanger, a first mounting component, a second mounting component, a power unit, and an anchor rod. The first mounting component is set according to the actual needs under different usage conditions to meet the good pulling direction of the anchoring mechanism and improve safety. There are multiple hangers, one end of which is connected to the first mounting component by a pin, and the other end is connected to the second mounting component by a pin. The upper and lower pins connect the first mounting component, the hanger, and the second mounting component to form a deformable rectangular structure, which meets the mobility of the anchoring mechanism 3 when tightening, so as to adapt to various slopes of the bridge deck.

[0024] In a further preferred embodiment of the present invention, the driving mechanism includes: a mounting shell 11 fixed on the mounting frame 8; a motor 12 assembled in the mounting shell 11; and gears 13 respectively fixed on the output shaft of the motor 12 and the rotating shaft 9 and meshing with each other.

[0025] In this embodiment, the motor 12 is started, and the output shaft of the motor 12 rotates, driving the gear 13 fixed thereto to rotate. The gear 13 drives another gear 13 meshing with it to rotate, which in turn drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the walking wheel 10 to rotate, realizing the self-propelled movement of the device. The motor 12 provides stable power, and the meshing transmission of the gear 13 makes the power transmission smoother.

[0026] In a further preferred embodiment of this utility model, a first electro-hydraulic rod 7 is fixedly installed on the frame 1, and the push rod of the first electro-hydraulic rod 7 is fixedly connected to the assembly frame 8 for adjusting lifting.

[0027] In this embodiment, activating the first electro-hydraulic rod 7 extends or retracts its push rod, causing the assembly frame 8 to rise or fall accordingly. Adjusting the height of the assembly frame 8 changes the contact state between the traveling wheels 10 and the bridge deck, facilitating adjustments to the height of the traveling wheels 10 according to construction needs. The first electro-hydraulic rod 7 is easy to operate and can stably drive the assembly frame 8 up and down, contributing to improved stability during the adjustment process. This structural design also enhances the device's adaptability to different construction scenarios, ensuring smooth subsequent movement or anchoring operations.

[0028] In a further preferred embodiment of the present invention, a second electro-hydraulic rod 14 and a third electro-hydraulic rod 15 are respectively fixedly installed on the frame 1 and the side arm 3. The push rod of the second electro-hydraulic rod 14 is fixedly connected to the side arm 3, and the push rod of the third electro-hydraulic rod 15 is fixedly connected to the base frame 4.

[0029] In this embodiment, the second electro-hydraulic rod 14 is activated, its push rod extends or retracts, causing the side arm 3 to move laterally to change the spacing; when adjusting the height of the base frame 4, the third electro-hydraulic rod 15 is activated, its push rod extends or retracts, causing the base frame 4 to rise or fall. The second electro-hydraulic rod 14 drives the side arm 3 to adjust the spacing, which can adapt to bridge bodies of different widths; the third electro-hydraulic rod 15 drives the base frame 4 to rise and fall, which can adjust the contact state between the guide wheel 6 and the bridge body.

[0030] In a further preferred embodiment of the present invention, guide blocks 17 are fixedly installed on both the frame 1 and the side arm 3. A guide rod 18 is slidably installed on the guide block 17. One end of the guide rod 18 is fixedly connected to the corresponding side arm 3 and the base frame 4 through a connecting block 20. A limit block 19 is fixedly installed on one end of the guide rod 18.

[0031] In this embodiment, guide blocks 17 are fixedly installed on the frame 1 and the side arm 3 respectively. The guide rod 18 is slidably installed on the guide block 17. Then, one end of the guide rod 18 is fixedly connected to the corresponding side arm 3 and the base frame 4 through the connecting block 20. Finally, a limiting block 19 is fixedly installed on one end of the guide rod 18 to complete the assembly.

[0032] When the side arm 3 moves laterally under the action of the second electro-hydraulic rod 14, it will cause the guide rod 18 to slide in the guide block 17 on the frame 1; when the base frame 4 is raised and lowered under the action of the third electro-hydraulic rod 15, it will cause the guide rod 18 to slide in the guide block 17 on the side arm 3.

[0033] In a further preferred embodiment of the present invention, a fourth electro-hydraulic rod 16 is fixedly installed on the base frame 4, and the push rod of the fourth electro-hydraulic rod 16 is fixedly connected to the assembly plate 5.

[0034] In this embodiment, when the position of the assembly plate 5 needs to be adjusted, the fourth electro-hydraulic rod 16 is activated. Its push rod extends or retracts, driving the assembly plate 5 to move laterally. The lateral adjustment of the assembly plate 5 can change the position of the guide wheel 6, allowing the guide wheel 6 to better contact the side of the bridge body. The fourth electro-hydraulic rod 16 is easy to operate and can stably drive the assembly plate 5 to move, which helps to improve the adaptability of the guide wheel 6 positioning, ensures the positioning effect of the guide wheel 6 auxiliary device, and facilitates the smooth progress of subsequent construction.

[0035] In a further preferred embodiment of the present invention, a maintenance plate is fixed to the mounting shell 11 by screws, and the maintenance plate has heat dissipation vents for ventilation.

[0036] In this embodiment, when it is necessary to inspect and repair components such as the motor 12 inside the mounting housing 11, the screws are unscrewed and the inspection plate is removed to inspect or repair the internal components; after the inspection and repair are completed, the inspection plate is then fixed back onto the mounting housing 11 with screws.

[0037] In summary, compared with related technologies, the adjustable design of the side arm 3, base frame 4, and assembly plate 5, combined with the guide wheel 6, enhances the device's adaptability to bridges of different specifications and facilitates initial positioning. With the help of the assembly frame 8, rotating shaft 9, traveling wheels 10, and drive mechanism, combined with the adjustment of the height of the assembly frame 8 by the first electro-hydraulic rod 7, the device achieves convenient and stable self-movement. The overall synergistic effect ensures construction safety, improves construction efficiency, and effectively solves the problem of inconvenient movement of existing devices.
