[0002] In modern bridge construction, the safety and stability of bridge structures have always been core concerns in the engineering field. Under the influence of natural disasters such as earthquakes and strong winds, as well as unexpected loads such as vehicle collisions, the main girder of a bridge may experience displacements exceeding the design limits. In severe cases, this can lead to girder collapse accidents, causing significant casualties and economic losses. Therefore, anti-girder collapse devices, as key components ensuring the safety of bridge structures, directly affect the service life and safety performance of bridges.

[0003] Currently, commercially available bridge anti-girder falling devices have many limitations. Some devices lack adjustment capabilities after the main girder has shifted, requiring manual intervention to restore it to its initial state. This not only increases maintenance costs and manpower input, but also makes it difficult for some devices to adapt to the differentiated protection needs of bridges with different spans and structural forms due to their limited adjustment functions.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a bridge anti-falling beam anchor support device that is easy to reset, comprising:

[0027] The support assembly 100 includes a base 101, a support seat 102 fixedly connected to the end of the base 101, a sleeve 103 slidably inserted into the side wall of the end of the support seat 102, and a support rod 104 inserted into the end of the sleeve 103.

[0028] The adjustment assembly 200 includes a fixed base 201 fixedly connected to the end of the support rod 104, a pad 202 inserted into the middle of the fixed base 201, a guide post 203 inserted into the middle of the pad 202, and a support plate 204 fixedly connected to the end of the guide post 203, the end of the support plate 204 extending to the outside of the fixed base 201.

[0029] The bridge anti-falling beam anchor support device of this utility model consists of a support assembly 100 and an adjustment assembly 200. In the support assembly 100, the base 101 serves as the basic load-bearing component, and its end is vertically fixedly connected to the support seat 102, which provides a guiding installation structure for the sleeve 103. The sleeve 103 is inserted into the end side wall of the support seat 102 through a sliding fit, forming a sliding pair that can move along the axial direction of the support seat 102; the support rod 104 is installed at the end of the sleeve 103 in an insert form, forming a telescopic adjustment structure. In the adjustment assembly 200, the fixed seat 201 is fixed to the top of the support rod 104, and the guide post 203 is installed through the middle of the pad 202. The upper and lower ends of the guide post 203 contact the support plate 204 and the side wall of the fixed seat 201, respectively. When subjected to force, the support plate 204 can move up and down along the guide post 203 to adjust the position of the beam anchor.

[0030] Specifically, the adjustment assembly 200 also includes a connecting rod 205 fixedly connected to the end of the fixed base 201, a connecting plate 206 fixedly connected to the middle of the connecting rod 205, a motor 207 fixedly connected to the middle of the connecting plate 206, and a lead screw 208 adapted to be installed at the end of the output shaft of the motor 207, with the upper end of the lead screw 208 threadedly connected to the end side wall of the pad 202.

[0031] The motor 207 is fixed to the middle of the connecting rod 205 via the connecting plate 206. A lead screw 208 is installed at the end of its output shaft. The lead screw 208 is threadedly connected to the side wall of the end of the pad 202 to form a helical transmission structure, which can lift the pad 202 to a certain height along the fixed seat 201, making it convenient to adjust the position of the beam anchor.

[0032] Furthermore, a retaining plate 209 is provided on the side wall of the fixed base 201, and a retaining block 210 is fixedly connected to the end of the connecting rod 205. The end of the retaining block 210 is engaged in the middle of the retaining groove inside the retaining plate 209.

[0033] The latch plate 209 on its side wall engages with the latch block 210 at the end of the connecting rod 205 to ensure that the connecting rod 205 is securely installed.

[0034] Furthermore, a spring is sleeved in the middle of the guide post 203, and the two ends of the spring in the middle of the guide post 203 are in elastic contact with the side wall of the support plate 204 and the fixed seat 201, respectively.

[0035] The spring sleeved in the middle of the guide column 203 provides elastic buffer support for the support plate 204, preventing hard collision between the beam anchor and the support components.

[0036] Preferably, a roller 105 is rotatably mounted on the side wall of the base 101, the roller 105 is symmetrically mounted on the side wall of the base 101, and a positioning post 106 is inserted in the middle of the base 101, with the bottom of the positioning post 106 extending to the bottom of the base 101.

[0037] Among them, the base 101 has rollers 105 symmetrically mounted on its side wall for easy movement and positioning of the device, and a positioning post 106 is provided in the middle for stable fixation by inserting it into the ground.

[0038] It should be noted that the bottom of the sleeve 103 is fixedly connected to a flange plate structure that mates with the slot on the side wall of the support 102, and the bottom flange plate of the sleeve 103 is threadedly connected to a handle bolt 107, the end of which is inserted into the middle of the insertion hole on the side wall of the support 102.

[0039] The sleeve 103 has a flange plate structure at the bottom, which fits precisely with the slot on the side wall of the support 102. The handle bolt 107 passes through the flange plate and the insertion hole on the side wall of the support 102 to achieve quick fixation of the sleeve 103. It also makes it easy to adjust the position of the sleeve 103 and to connect with the fixing seat 201 of different sizes.

[0040] Preferably, the sleeve 103 has a threaded connection to a pin 108 on its side wall, and the end of the pin 108 is inserted into a pin hole on the side wall of the support rod 104.

[0041] The sleeve 103 is also provided with a threaded hole on its side wall, which is used to insert the pin rod 108 into the pin hole on the side wall of the support rod 104 to achieve the positioning of the support rod 104.

[0042] During use and installation, the base 101 is first moved to the predetermined position using rollers 105, and then the positioning column 106 is inserted into the ground to fix the base 101. Depending on the actual needs of the bridge, the height of the sleeve 103 on the support base 102 can be adjusted by loosening the handle bolt 107, and then tightening the handle bolt 107 for fixation; the extension length of the support rod 104 within the sleeve 103 can be adjusted by loosening the pin rod 108, and then the pin rod 108 can be inserted for positioning. When the bridge is displaced by external forces, the support plate 204 is initially stressed, compressing the spring along the guide column 203. The spring provides buffering force to absorb some of the impact energy. If the height of the support plate 204 needs to be actively adjusted, the motor 207 is started. The motor 207 drives the lead screw 208 to rotate, which, through the lead screw nut, drives the pad 202 to move up and down along the lead screw 208, thereby raising and lowering the support plate 204 to meet the protection requirements under different working conditions.

[0043] In summary, the cooperation between the spring and the guide column 203 allows the support plate 204 to automatically reset after deformation under stress, reducing the frequency of manual maintenance and adjustment and improving the ease of use of the device. The telescopic structure of the sleeve 103 and the support rod 104 in the support assembly 100, combined with the screw drive mechanism in the adjustment assembly 200, enables multi-dimensional adjustment of the device in three-dimensional space, adapting to different bridge structures and installation environments. The combination of the roller 105 and the positioning column 106 facilitates rapid movement and positioning of the device, while the quick-connect structure such as the handle bolt 107 and the pin rod 108 greatly shortens the installation time and improves construction efficiency. The design of the snap-fit ​​structure of the connecting rod 205 and the fixed seat 201, as well as the screw drive of the screw rod 208, ensures the structural stability of the adjustment assembly 200; the fixing method of the sleeve 103 with the flange plate and the slot enhances the load-bearing capacity of the support assembly 100, ensuring the stability and reliability of the device in bridge protection.
