[0002] The self-propelled bridge building machine mainly includes a load-bearing system, hooks and travel rails, template system, anchoring system, front suspension mechanism, traction mechanism, etc. Its load-bearing system includes the bridge building machine crossbeam frame, with drive wheels at both ends to drive the main body of the bridge building machine to move on the bridge. When the main body of the bridge building machine moves to a suitable position on the bridge, the staff needs to anchor the main body of the bridge building machine to the bridge.

[0003] The existing bridge-building machine anchoring device requires the installation of anchoring mechanisms according to the reserved hole positions on the beam during use. Therefore, workers need to frequently use nuts and bolts to connect the main body of the bridge-building machine to the beam. The installation and disassembly process is time-consuming and labor-intensive, affecting the efficiency of the device's erection and dismantling. Utility Model Content

[0020] See Figures 1-3 As shown, this utility model provides an anchoring device for a bridge-building machine, including a bridge-building machine crossbeam frame 1, which serves as a support for the main body of the bridge-building machine. Drive wheels 11 are installed at both ends of the bottom of the crossbeam frame 1 to control the movement of the main body of the bridge-building machine. It also includes steel rails 3 fixed to both sides of the bridge deck by bolts. The top of the steel rails 3 has an integrally formed protruding rib 31 fixed along its length. Through holes 32 are evenly distributed along the length of the sides of the protruding ribs 31. Sliding openings are provided at both ends of the bridge-building machine crossbeam frame 1. An L-shaped adjusting plate 2 is slidably inserted into the sliding opening. A pushing mechanism 7 is fixedly installed at the bottom of both ends of the bridge-building machine crossbeam frame 1. The pushing mechanism 7 is used to control the extension and retraction of the L-shaped adjusting plate 2. A clamping plate 4 is slidably installed at the bottom of the L-shaped adjusting plate 2. An adjusting mechanism 5 is installed at one end of the L-shaped adjusting plate 2. The adjusting mechanism 5 is used to drive the clamping plate 4 to move along the length of the rail 3. A locking mechanism 6 is installed on one side of the clamping plate 4. A pin is fixedly installed at one end of the locking mechanism 6. The locking mechanism 6 is used to control the pin to disengage or insert into the through hole 32.

[0021] In this embodiment, the pushing mechanism 7 is a hydraulic cylinder, and its output shaft is fixedly connected to the corresponding L-shaped adjusting plate 2.

[0022] In this embodiment, the clamping plate 4 includes a first clamping plate 41, a second clamping plate 42, and a slider 43. The bottom of the L-shaped adjusting plate 2 is provided with a sliding groove 21. The first clamping plate 41 and the second clamping plate 42 are slidably installed in the sliding groove 21. The two ends of the slider 43 are fixedly connected to the upper ends of the first clamping plate 41 and the second clamping plate 42, respectively. The adjusting mechanism 5 is used to drive the slider 43 to move along the length direction of the sliding groove 21.

[0023] In this embodiment, the adjusting mechanism 5 is a lead screw motor, and a through threaded hole is provided in the middle of the side surface of the slider 43. The lead screw shaft of the lead screw motor is connected to the threaded hole.

[0024] Furthermore, in this embodiment, the locking mechanism 6 is an electric push rod, which is fixedly installed on the outside of the first clamping plate 41. The piston shaft of the electric push rod is fixedly connected to the pin. The second clamping plate 42 is flush with the position of the piston shaft of the electric push rod and has a positioning hole 44 for the insertion of the pin.

[0025] Furthermore, in order to achieve automated detection of the positional change of the L-shaped adjusting plate 2 on the protruding rib 31, in this embodiment, positioning pieces 33 are fixedly installed on the upper surface of the protruding rib 31, flush with the position of the through hole 32, and a laser sensor 8 is fixedly installed at the bottom center of the L-shaped adjusting plate 2. The laser sensor 8 is used to detect the position of the positioning pieces 33.

[0026] In this embodiment, the laser sensor 8 controls the extension and retraction of the lead screw motor and electric push rod via a PLC. This part is existing technology and will not be described in detail here.

[0027] The specific operating steps are as follows: The clamping plate 4 is mounted on the protruding rib 31. When the main body of the bridge-building machine moves to the set position, the position of the positioning piece 33 is detected by the laser sensor 8. When the position of the positioning piece 33 changes, the position of the reflected light point on the photosensitive element shifts accordingly. The laser sensor 8 measures this shift and, combined with trigonometric function relationships, accurately calculates the distance and position change between the positioning piece 33 and the laser sensor 8. Then, the control algorithm set by the PLC controls the rotation of the lead screw motor to adjust the position of the clamping plate 4 on the protruding rib 31, so that the pin can accurately correspond to the positioning hole 44 at the position of the positioning piece 33. Then, the electric push rod is driven to insert the pin into the through hole 32 and the positioning hole 44, so that the clamping plate 4 can be stably placed on the rail 3, preventing the main body of the bridge-building machine from moving.
