[0001] The utility model relates to the technical field of bridge construction platforms, in particular to a bridge bottom surface construction platform. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, or seas to facilitate the passage of vehicles and pedestrians. To adapt to the rapid development of modern transportation, the term "bridge" has also been extended to encompass structures built to facilitate travel across mountain streams, difficult terrain, or other transportation needs. During bridge construction, work on the base of the bridge is necessary. However, due to its suspended structure and the inconvenience of access to rivers and mountain streams below, specialized equipment is required for this work.

[0003] Existing construction platforms at the bottom of bridges have some defects when in use: they cannot be adjusted in real time according to the changes in the construction position at the bottom of the bridge. Whether along the length or width of the bridge, they cannot be adjusted according to the immediate requirements of the construction workers. In addition, most construction platforms cannot be moved to the sides of the bridge bottom during construction, which has certain limitations in their overall use.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a bridge bottom surface construction platform. Utility Model Content

The lifting components are detachably installed at both ends of the horizontal moving component, and the lifting components on both sides operate synchronously to adjust the construction height of the construction platform 12. A transfer locomotive 26 that moves along the length direction of the bridge 10 is connected to the top of the lifting component, and the transfer locomotives 26 on both sides operate synchronously. Under the connection and cooperation of the lifting component and the horizontal moving component, the construction platform 12 is adjusted to the front and rear side positions of the bottom of the bridge 10, so as to achieve the effect of real-time controlled transfer construction of any position of the bottom of the bridge 10 by the workers placed on the construction platform 12.

[0018] In the embodiment of the present invention, a weight block 25 is installed on the top of the transfer locomotive 26. The gravity of the weight block 25 is used to increase the stability of the transfer locomotive 26 during movement. That is, the transfer locomotive 26 is connected to the horizontal moving assembly at the bottom under the connection of the lifting assembly. The lifting assembly, the horizontal moving assembly, and the construction platform 12 are all placed at the bottom of the bridge 10. The pressure of the weight block 25 maintains the balance of the upper and lower sides.

[0019] Outwardly inclined bridge eaves 11 are installed on both sides of the bridge 10. The top of the lifting assembly is fixedly connected to the transfer locomotive 26 through a U-shaped connecting rod 24. The U-shaped opening of the U-shaped connecting rod 24 is inserted into the outside of the bridge eaves 11, which is used to increase the anti-fall ability of the connection between the transfer locomotive 26 and the lifting assembly to a certain extent.

[0020] A circle of fences is evenly installed on the top edge of the construction platform 12 to increase the safety of workers when they are working on the construction platform 12.

[0021] In one embodiment of the present invention, the horizontal movement assembly includes a support rod 13 fixedly mounted on the bottom middle portion of the construction platform 12, a nut 16 fixedly connected to the bottom of the support rod 13, a horizontally distributed lead screw 17 threadedly connected to the middle portion of the nut 16, a guide device for limiting its rotation is provided on the nut 16, and end plates 18 are provided at both ends of the lead screw 17. One end of the lead screw 17 is connected to a servo motor 20 fixed inside the end plate 18, and the other end is rotatably connected to the end plate 18. That is, the servo motor 20 is started to drive the lead screw 17 to rotate, thereby driving the nut 16 to move back and forth laterally along the lead screw 17, thereby adjusting the lateral position of the construction platform 12;

[0022] The end plate 18 is detachably connected to a connecting block 22 on the side away from the lead screw 17. The end of the connecting block 22 is fixedly connected to the lifting assembly. The lifting assembly is configured as an elevator 23. The top of the elevator 23 is fixedly connected to the bottom of the U-shaped connecting rod 24 through a connecting plate. The bottom output end of the elevator 23 is fixedly connected to the top of the connecting block 22. That is, under the lifting action of the elevator 23, the height of the connecting block 22 is directly adjusted to control and adjust the construction height of the construction platform 12.

[0023] A clamping block 19 is installed in the middle of the side wall of the end plate 18 away from the screw 17. The end of the clamping block 19 is plug-in connected with a clamping slot 21. The clamping slot 21 is opened on the connecting block 22. The clamping block 19 is clamped with the clamping slot 21 to realize the detachable connection between the end plate 18 and the connecting block 22.

[0024] As a preferred embodiment of the present invention, in order to increase the stability of the construction platform 12 when it moves laterally along the screw 17, two groups of balancing slides 15 are symmetrically arranged on both sides of the screw 17. The two ends of the balancing slide 15 are rotatably connected to the end plate 18. A balancing slide 14 is installed at the bottom of the construction platform 12 corresponding to the position of the balancing slide 15. The balancing slide 14 slides along the balancing slide 15, that is, under the sliding support of the balancing slide 14 and the balancing slide 15 on both sides, the lateral movement of the construction platform 12 is kept stable.

[0025] As a preferred embodiment of the present invention, in order to keep the two sets of transfer locomotives 26 in a constant forward direction when moving, a fixed rod 27 is installed on one side of the upper part of the elevator 23. The end of the fixed rod 27 is rotatably connected to a positioning wheel 28 through a wheel frame 29. The end of the positioning wheel 28 is in rolling contact with the side wall of the bridge 10. When the transfer locomotives 26 on both sides move, the lateral position of its construction platform 12 is kept stable under the rolling restriction of the positioning wheel 28 and the side wall of the bridge 10.

[0026] The working principle of the present utility model is: in the idle part of the device, all the above-mentioned driving parts, which refer to power elements, electrical components and adaptive power supplies, are connected through wires, and the electrical connections are completed in a working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, according to the width of the bridge 10, a screw 17 of appropriate length is selected, and then the end plates 18 at both ends of the screw 17 are used to connect it to the connecting block 22 through the connection method of the clamping block 19 and the clamping slot 21, and then the elevator 23 is connected to the transfer locomotive 26. At this time, the positioning wheel 28 is in rolling contact with the side wall of the bridge 10 to maintain the forward moving direction of the transfer locomotive 26. Then the staff is placed on the construction platform 12. According to the requirements of the construction position at the bottom of the bridge 10, the operation of the elevator 23, the transfer locomotive 26 and the servo motor 20 are controlled to adjust the horizontal, height and front and rear positions of the construction platform 12 in real time, so as to perform covering construction at any position at the bottom of the bridge 10.
