[0030] Example 1

[0031] See also Figure 1-4 , the utility model provides the following technical solutions:

[0032] A foundation construction device for a bridge pier safety ladder, comprising:

[0033] Platform 1;

[0034] Ladder frame 2, ladder frame 2 is arranged at the side end of platform 1;

[0035] A round rod 3, the round rod 3 being rotatably connected between the platform 1 and the ladder frame 2; and

[0036] The adjustment mechanism is arranged at the lower end of the platform 1 to achieve different height adjustments during construction.

[0037] In a specific embodiment of the present invention, platform 1 serves as the base platform of the entire device, is used to carry the ladder frame 2 and other components, and provides a stable working platform. The ladder frame 2 is arranged at the side end of the platform 1 for workers to climb in order to carry out bridge pier construction or maintenance work. The round rod 3 is rotatably connected between the platform 1 and the ladder frame 2. Through the rotational connection of the round rod 3, the ladder frame 2 can rotate within a certain range to adapt to the position and angle of different bridge piers. The adjustment mechanism is arranged at the lower end of the platform 1 to achieve different height adjustments during construction, ensuring that the ladder frame 2 can adapt to the construction requirements of bridge piers of different heights.

[0038] For details, please refer to Figure 1-4The adjusting mechanism includes a connecting rod 5, a sleeve 6, a base plate 7 and a driving assembly. The connecting rod 5 is fixedly connected to the lower end of the platform 1, the sleeve 6 is sleeved and connected to the connecting rod 5, the base plate 7 is fixedly connected to the lower end of the sleeve 6, and the driving assembly is arranged on the base plate 7 to realize the lifting and lowering adjustment of the connecting rod 5.

[0039] In this embodiment, a connecting rod 5 is fixedly connected to the lower end of platform 1 and serves as the primary support for the adjustment mechanism. A sleeve 6 is sleeved and connected to connecting rod 5, and height adjustment is achieved through relative movement between sleeve 6 and connecting rod 5. A base plate 7 is fixedly connected to the lower end of sleeve 6 and serves as the bottom support for the entire adjustment mechanism. A drive assembly is mounted on base plate 7 to achieve the vertical adjustment of connecting rod 5.

[0040] For details, please refer to Figure 1-4 The driving assembly includes a mounting seat 9, a rotating rod 10, a tooth mouth 11 and a gear 12. The mounting seat 9 is fixedly connected to the upper end of the base plate 7. The rotating rod 10 is rotatably connected to the mounting seat 9. The tooth mouth 11 is opened on the connecting rod 5. The gear 12 is fixedly connected to the rotating rod 10, and the gear 12 is engaged with the tooth mouth 11.

[0041] In this embodiment: the mounting base 9 is fixedly connected to the upper end of the base plate 7, and is used to install the rotating rod 10 to ensure that the rotating rod 10 can rotate stably. The rotating rod 10 is rotatably connected to the mounting base 9, and one end of the rotating rod 10 can be driven by a manual knob or an electric motor. When the rotating rod 10 rotates, the gear 12 fixed thereon will also rotate accordingly. The tooth opening 11 is opened on the connecting rod 5 and meshes with the gear 12. When the gear 12 rotates, the tooth opening 11 will move along the tooth shape of the gear 12, thereby driving the connecting rod 5 to move up and down. The gear 12 is fixedly connected to the rotating rod 10 and meshes with the tooth opening 11. The rotation of the gear 12 can accurately control the lifting and lowering of the connecting rod 5, thereby realizing the height adjustment of the platform 1.

[0042] For details, please refer to Figure 1-4 The upper end of the base plate 7 is fixedly connected to a mounting platform 13 , the upper end of the mounting platform 13 is fixedly connected to a motor 14 , and the output end of the motor 14 is connected to the rotating rod 10 .

[0043] In this embodiment: the base plate 7 is fixedly connected to the lower end of the sleeve 6, serving as the bottom support of the entire adjustment mechanism. The design of the base plate 7 makes the entire device more stable, and the lifting and lowering of the connecting rod 5 can be controlled by the drive assembly on the base plate 7. The design of the mounting platform 13 is mainly used to install the motor 14, ensuring that the motor 14 can be stably fixed on the base plate 7 and providing sufficient support for the motor 14. The motor 14 is used to drive the rotation of the rotating rod 10, thereby achieving the lifting and lowering adjustment of the connecting rod 5. The selection of the motor 14 can select the appropriate power and speed according to actual needs to meet the requirements of different height adjustments. The output end of the motor 14 is connected to the rotating rod 10. In this way, the motor 14 can directly drive the rotation of the rotating rod 10. The output end of the motor 14 usually has a coupling or other connecting device for reliable connection with the rotating rod 10 to ensure smooth and efficient power transmission.

[0044] For details, please refer to Figure 1-4 The bottom plate 7 and the lower end of the ladder frame 2 are fixedly connected with a universal wheel 8.

[0045] In this embodiment, the design of universal wheels 8 allows the entire device to be freely moved on the ground, making it easy for the operator to quickly move the equipment to the desired location. Universal wheels 8 are also fixedly connected to the lower end of the ladder frame 2. By installing universal wheels 8 at the lower end of the ladder frame 2, the ladder frame 2 can be freely moved on the horizontal surface, further enhancing the flexibility of the device.

[0046] For details, please refer to Figure 1-4 A protective frame 4 is fixedly connected between the platform 1 and the ladder frame 2.

[0047] In this embodiment, the protective frame 4 serves as a connecting structure between the platform 1 and the ladder frame 2, which not only enhances the structural stability of the entire device, but more importantly, provides a protective function, which can prevent workers from falling during the climbing process.

[0048] The working principle and usage process of the present invention are as follows: first, when in use, unlock the braking device of the universal wheel 8 and push the equipment to the desired position. After reaching the designated position, lock the universal wheel 8 to ensure that the equipment is stable and immovable. Adjust the height of the equipment according to actual needs and start the motor 14. The motor 14 drives the rotating rod 10 to rotate, thereby driving the connecting rod 5 to move up and down in the sleeve 6 to achieve height adjustment of the platform 1. After adjusting to the appropriate height, stop the motor 14 and ensure that the locking device between the connecting rod 5 and the sleeve 6 is in a locked state to prevent the equipment from sliding during use. Before use, check again whether all connection parts are firm to ensure that the equipment is in a safe state and check whether the protective frame 4 is intact to ensure that it can provide the necessary safety protection. The staff climbs to the required height through the ladder frame 2 to carry out bridge pier construction or maintenance work. During the construction process, the staff can rely on the protective frame 4 for assistance and protection to ensure safe operation. After the construction is completed, the staff safely evacuates the ladder frame 2.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
