[0016] This utility model provides a structural locking device for a bridge-building machine, the structure of which is as follows: Figures 1-4 As shown, the system includes two main beams 1, each with a transverse slide rail 2 fixed to its outer side. A top plate 5 is mounted above each beam. Slide seats 4 are slidably connected to each of the two transverse slide rails 2, and each slide seat 4 has several evenly distributed locking holes 3 on its outer side. Two support rods 6 are fixed to the outer side of each slide seat 4, and each slide seat 4 has a support block 7 and a locking element 8. The tops of the support rods 6 are fixed to the bottom surface of the top plate 5. The support block 7 is fixed between the two support rods 6 and has a first through hole 9 on its side. A second through hole 10 is also opened on the outer side of the slide seat 4. The locking element 8 includes a cylinder 801, a trapezoidal block 802, and two limiting blocks 804. The cylinder 801 has two opposing slots 805 on its side, one end of which passes through the first through hole 9 and the second through hole 10 and is located in the locking hole 3. A trapezoidal block 802 is located inside the cylinder 801, and a bearing 806 is fixed to its side. Two limiting blocks 804 are slidably connected to the two slots 805 respectively. One end of the limiting block 804 has an inclined surface structure adapted to the trapezoidal block 802, and a connecting block 807 is fixed to the side of one end. The connecting block 807 is connected to the cylinder 801 by a spring 808. The other end of the cylinder 801 is threaded with a bolt 803, one end of which is connected to the bearing 806. Using the structural locking device of the bridge-building machine allows for precise positioning and rapid assembly / disassembly, which is beneficial for improving the construction progress.

[0017] Furthermore, the other end of the cylinder 801 has a thread 809 on its side and is threadedly connected to a threaded sleeve 810, and several levers 811 are fixed on the side of the threaded sleeve 810.

[0018] Furthermore, the trapezoidal block 802 is connected to the inner wall of the cylinder 801 by two telescopic rods 812.

[0019] Furthermore, several crossbars 12 are fixed between the two main beams 1.

[0020] Furthermore, a hoisting component 11 is installed on the top surface of the top plate 5.

[0021] Furthermore, vertical rods 13 are fixed to the outer sides of both slides 4, and a support plate 14 is fixed between the two vertical rods 13.

[0022] Operating procedures During operation, firstly, adjust the position of the slide block 4 on the transverse slide rail 2 according to construction needs, aligning the second through hole 10 on the outer side of the slide block 4 with the corresponding locking hole 3 on the transverse slide rail 2. Then, pass one end of the cylindrical part 801 of the locking component 8 through the first through hole 9 of the support block 7 and the second through hole 10 of the slide block 4 in sequence, until the end of the cylindrical part 801 enters the locking hole 3. Next, rotate the bolt 803 to make it rotate forward within the cylindrical part 801. The bolt 803 pushes the trapezoidal block 802 to move axially along the cylindrical part 801. At this time, the inclined surface of the trapezoidal block 802 presses against the two limiting blocks 804, causing the limiting blocks 804 to slide outward along the groove 805 and tightly abut against the inner wall of the locking hole 3, completing the locking action. Simultaneously, rotate the threaded sleeve 810 by using the lever 811, causing it to screw in along the thread 809 on the outside of the cylinder to complete the locking of the entire structure. Under the action of the telescopic rod 812, the trapezoidal block 802 maintains stable movement, while the spring 808 provides a restoring force for the limiting block 804. When unlocking is required, the bolt 803 is rotated in the opposite direction, causing the trapezoidal block 802 to retract. Under the tension of the spring 808, the limiting block 804 retracts into the slot 805, allowing the cylinder 801 to be pulled out of the locking hole 3, thus adjusting the position of the slide 4. During this process, the crossbar 12 enhances the overall stability of the main beam 1, the support plate 14 provides a convenient operating platform for the operator, and the lifting component 11 facilitates the overall handling and installation of the device.

[0023] Beneficial effects This device effectively solves the problem of insufficient locking strength in traditional bridge-building machine locking devices. Through the inclined surface cooperation between the trapezoidal block 802 and the limiting block 804 in the locking component 8, the limiting block 804 can evenly abut against the inner wall of the locking hole 3 during locking, significantly increasing the contact area, dispersing stress, avoiding structural failure caused by localized wear, and significantly improving locking strength and durability. Addressing the issue of cumbersome operation, the device adopts a linkage structure of bolt 803 and threaded sleeve 810, combined with a lever 811, enabling quick operation by a single person without the need for multiple people. Simultaneously, the sliding design of the slide block 4 on the transverse slide rail 2, combined with multiple sets of locking holes 3, allows the device to flexibly adapt to different span construction needs, reducing disassembly and reinstallation time and improving construction efficiency. For the problem of difficulty in judging the locking status, the outward movement of the limiting block 804 can directly reflect whether the locking is in place, allowing operators to monitor the locking status in real time and reducing safety hazards. Under complex working conditions, the elastic force of spring 808 can automatically compensate for the displacement of limit block 804 caused by vibration or temperature changes, ensuring stable locking force, reducing the frequency of manual periodic inspection and adjustment, and lowering maintenance costs. Furthermore, the device adopts a universal design for all components. The crossbar 12 enhances the overall stability of the main beam 1, the vertical bar 13 and support plate 14 provide a convenient operating platform, and the lifting component 11 facilitates overall handling. It is applicable to various models of bridge-building machines, promoting standardized production and further reducing equipment maintenance costs. Simultaneously, the telescopic rod 812 ensures the stability of the trapezoidal block 802's movement, preventing offset during locking and improving operational precision. Overall, this device demonstrates excellent performance in terms of locking reliability, ease of operation, environmental adaptability, and versatility, fully meeting the high-performance requirements of modern bridge construction for bridge-building machine structural locking devices.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
