DETAILED DESCRIPTION

[0029] The utility model is now described in further detail with reference to the accompanying drawings.

[0030] See also Figures 1 to 8The utility model provides a technical solution: a viaduct anti-falling beam device, comprising a U-shaped high-strength bolt kit 1, a U-shaped high-strength bolt inner part 2, a kit fixing strip 4 and an inner part fixing strip 5, an inner groove 3 for embedding the U-shaped high-strength bolt inner part 2 is provided in the middle of the U-shaped high-strength bolt kit 1, and grooves for extension rods 12 are provided inside both ends of the U-shaped high-strength bolt inner part 2, a kit fixing strip 4 is sleeved on the lower end of the U-shaped high-strength bolt kit 1, and an inner part fixing strip 5 for fixing the U-shaped high-strength bolt inner part 2 is provided below the kit fixing strip 4;

[0031] The middle parts of the U-shaped high-strength bolt set 1, the U-shaped high-strength bolt inner part 2, the set fixing strip 4, and the inner part fixing strip 5 are all penetrated with a reserved hole 6 for the connection assembly to penetrate;

[0032] The outside of the U-shaped high-strength bolt kit 1 and the extension rod 12 are both provided with threads for the first nut 7 to be screwed into. Considering that the guardrail is currently mostly fixed with eight-shaped fasteners or rotatable cross fasteners in combination with high-strength bolts to fix the cross-shaped steel pipes, but their size is large, and the workers need to carry fasteners, high-strength bolts and nuts at the same time during the assembly operation, so there is a disadvantage of limited carrying quantity. The present connection structure will use the U-shaped high-strength bolt kit 1, the U-shaped high-strength bolt inner part 2, the kit fixing strip 4 and the inner part fixing strip 5 which are arranged in a cross shape after unfolding to fix the two cross-shaped steel pipes, and because the U-shaped high-strength bolt inner part 2 can be accommodated in the embedded groove 3 of the U-shaped high-strength bolt kit 1 and the kit fixing strip 4 can overlap with the inner part fixing strip 5, the size of the present connection structure is further reduced, that is, compared with the existing cross fastener, the size is reduced and the amount of carrying by the workers is increased.

[0033] Among them, both ends of the embedded groove 3 are provided with plug-in grooves 8 for the extension stud to pass through. The plug-in grooves 8 are provided to place the extension rod 12 of the U-shaped high-strength bolt inner part, thereby avoiding the misalignment of the U-shaped high-strength bolt inner part and the U-shaped high-strength bolt kit when the workers carry the structure, thereby increasing the occupied space of the structure. The existence of the plug-in grooves 8 can fix the U-shaped high-strength bolt inner part by plugging in the extension rod 12, thereby making the U-shaped high-strength bolt kit overlap with the U-shaped high-strength bolt inner part and reducing the occupied space.

[0034] Among them, guide grooves compatible with the guide rails 9 are opened on both sides of the top of the extension rod 12, and the guide rails 9 are fixedly installed inside the groove body. A first giveway groove 11 for the first lever 10 to pass through is opened at the front end of the extension rod 12, and the first lever 10 is fixed to the extension rod 12. A return spring 13 is abutted between the top of the extension rod 12 and the inner top of the groove body. By setting the return spring 13, the extension rod 12 is abutted inside the plug-in groove 8 to prevent the extension rod 12 from slipping out of the plug-in groove 8 without force. When the U-shaped high-strength bolt inner part 2 needs to be unfolded, the first lever 10 is toggled to make the extension rod 12 rise and compress the return spring 13. At this time, the bottom of the extension rod 12 is out of the plug-in groove 8. At this time, the U-shaped high-strength bolt inner part 2 can be rotated, that is, the U-shaped high-strength bolt inner part 2 is rotated outside the sleeve 18 until the U-shaped high-strength bolt inner part 2 and the external U-shaped high-strength bolt kit 1 are cross-shaped.

[0035] Among them, cavities for the extension blocks 14 to move are opened inside the two ends of the inner part fixing strip 5, and alignment holes 15 for the bottom of the U-shaped high-strength bolt inner part 2 to pass through are opened in the middle of the two extension blocks 14, and a second lever 16 is fixed to the front end of the two extension blocks 14. The front ends of the two cavities are respectively connected to the second clearance grooves 17 on both sides of the front end of the inner part fixing strip 5. The arrangement of the alignment holes 15 facilitates the insertion of the U-shaped high-strength bolt inner part 2 into the inner part fixing strip 5.

[0036] Among them, the two connecting components include a sleeve 18, a reinforcing carriage bolt 19 and a second nut 20. The outer size of the sleeve 18 is smaller than the inner size of the reserved hole 6. The reinforcing carriage bolt 19 is installed inside the sleeve 18, and the bottom thread of the reinforcing carriage bolt 19 is connected. The reinforcing carriage bolt 19 and the second nut 20 are in contact with the surface of the sleeve 18. The sealing anti-skid ring 21 is made of rubber. By setting the connecting component, the U-shaped high-strength bolt kit 1 and the U-shaped high-strength bolt inner part 2 and the kit fixing strip 4 and the inner part fixing strip 5 are connected. It plays the role of a movable connection. By setting the shaft sleeve 18 and using the second nut 20 and the reinforced carriage bolt 19 for installation, it is convenient for the later user to loosen the second nut 20 to disassemble the shaft sleeve 18. After the shaft sleeve 18 is disassembled, the disassembly between the U-shaped high-strength bolt kit 1, the U-shaped high-strength bolt inner part 2 and the kit fixing strip 4 and the inner part fixing strip 5 can be completed. This structure allows the later workers to replace the damaged parts, and since the upper and lower ends of the shaft sleeve 18 are provided with sealing anti-skid rings 21, rainwater is prevented from entering the inside of the shaft sleeve 18 to cause rust.

[0037] Among them, the outer side of the contact end between the reinforcing carriage bolt 19 and the anti-fall beam steel bar is sleeved with a protective cap 22, and the material of the protective cap 22 itself is rubber material. By setting the protective cap 22, the contact surface between the reinforcing carriage bolt 19 and the anti-fall beam steel bar is protected, avoiding the surface contact between the reinforcing carriage bolt 19 and the anti-fall beam steel bar to cause wounds.

[0038] The specific usage and function of this embodiment are as follows:

[0039] During use, first push the first lever 10 upward to make the extension rod 12 rise and compress the reset spring 13. At this time, the bottom of the extension rod 12 disengages from the insertion slot 8. At this time, the U-shaped high-strength bolt inner part 2 can be rotated, that is, the U-shaped high-strength bolt inner part 2 is rotated outside the sleeve 18 until the U-shaped high-strength bolt inner part 2 and the external U-shaped high-strength bolt kit 1 are cross-shaped, and then the unfolded U-shaped high-strength bolt inner part 2 and the U-shaped high-strength bolt kit 1 are clamped in the cross-shaped steel pipe depression, and then the kit fixing strip 4 and the inner part fixing strip 5 are taken out and connected with the U-shaped high-strength bolt inner part 2 and the U-shaped high-strength bolt kit 1, and then the first nut 7 is tightened to complete the fixation of the two cross-shaped anti-drop beam steel bars by this structure, and the above process can be repeated to complete the fixation of the anti-drop beam.

[0040] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
