Description

Technical Field

[0001] The utility model belongs to the technical field of bridge railings, in particular to a bridge railing with a quick installation function. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. Bridge railings are often installed on the edge of the bridge to act as a barrier. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the function of preventing vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure, to ensure the safety of pedestrians and vehicles passing on the bridge deck.

[0003] At present, the existing bridge railings are generally composed of columns and beams. When installing the bridge railings, the beams need to be fixed on the columns first, and then the columns are fixed at the locations where the railings need to be installed. Most of them use welding to fix the beams on the columns, which is cumbersome and costly. In addition, the welded beams and columns cannot be separated, which is inconvenient for later maintenance and replacement of the bridge railings. Some of them use a large number of bolts to connect and fix the beams and columns, and the staff need to tighten multiple bolts one by one, which is a large workload and increases the workload of the staff, making the installation efficiency of the bridge railings low.

[0004] In view of the above problems, we propose a bridge railing with a quick installation function. Utility Model Content

DETAILED DESCRIPTION

[0023] This specific embodiment is a bridge railing with a quick installation function, such as Figure 1-Figure 7 As shown, the bridge railing with quick installation function includes a fixed column 1 and a cross bar 2, a plurality of U-shaped blocks 3 are fixed on both sides of the fixed column 1, the end of the cross bar 2 cooperates with the inner cavity of the U-shaped block 3, an insert block 4 is fixed on the inner side of the U-shaped block 3, a positioning hole 5 is penetrated on the insert block 4, a plurality of positioning grooves 6 are opened on both sides of the fixed column 1, which are on the same axis as the positioning hole 5, slots 7 are opened on both sides of the bottom of the cross bar 2, which cooperate with the insert block 4, the cross bar 2 is a hollow structure, through holes are penetrated on the left and right sides of the inner cavity of the cross bar 2, a positioning rod 11 is movably arranged in the through hole, a screw rod 9 is rotatably connected to the upper side of the inner cavity of the cross bar 2, a movable plate 10 is threadedly arranged on the screw rod 9, the outer end of the positioning rod 11 cooperates with the positioning hole 5 and the positioning groove 6, the inner end of the positioning rod 11 is fixed with an extrusion plate 12, and connecting arms 13 are hinged between the two ends of the movable plate 10 and the extrusion plates 12 on both sides.

[0024] By matching the end of the cross bar 2 with the inner cavity of the U-shaped block 3, it is convenient to adjust the two ends of the cross bar 2 to be respectively inserted into the corresponding inner sides of the two U-shaped blocks 3, and at the same time, the plug block 4 is inserted into the corresponding slot 7. Under the threaded cooperation of the screw rod 9 and the movable plate 10, it is convenient to adjust the movable plate 10 to move downward. Combined with the hinged effect at both ends of the connecting arm 13, the extrusion plate 12 is squeezed in the direction away from the screw rod 9, thereby driving the positioning rod 11 to slide outward along the direction of the through hole until the positioning rod 11 passes through the positioning hole 5 on the plug block 4 and is inserted into the corresponding positioning groove 6 on the fixed column 1, so that the fixed column 1 and the cross bar 2 are fixed. The bridge railings are fixedly connected to the plug block 4 without the need for welding or multiple bolts. This solves the problem that most of the prior art uses welding to fix the beam on the column, which is cumbersome and costly, and the welded beam and column cannot be separated, making it inconvenient to maintain and replace the bridge railings in the later stage. At the same time, it solves the problem that some of the prior art uses a large number of bolts to connect and fix the beam and the column, requiring staff to tighten multiple bolts one by one, which is a large workload, increases the workload of staff, and makes the installation efficiency of the bridge railings low.

[0025] A rotating shaft 8 is rotatably provided at the lower side of the inner part of the cross bar 2, and the upper end of the rotating shaft 8 is fixedly connected to the lower end of the screw rod 9. Two connecting ropes 14 are fixed on the rotating shaft 8, and the end of the connecting rope 14 away from the rotating shaft 8 is fixedly connected to the extrusion plate 12. A knob 19 is rotatably provided at the bottom of the cross bar 2, and the upper end of the knob 19 is fixedly connected to the end of the rotating shaft 8 away from the screw rod 9. The knob 19 is used to facilitate the rotation of the rotating shaft 8, thereby facilitating the installation, fixation, and disassembly and replacement of the cross bar 2.

[0026] A plurality of anti-collision blocks 15 are fixed to the front surface of the crossbar 2, and the anti-collision blocks 15 are arc-shaped structures. The anti-collision effect of the bridge railing is effectively improved by the arc-shaped anti-collision blocks 15.

[0027] Guide rods 16 are provided on both sides of the screw rod 9, and the upper ends of the guide rods 16 are fixedly connected to the top of the inner cavity of the cross bar 2. Two guide holes are relatively penetrated on the movable plate 10, and the guide rods 16 and the guide holes are movably cooperated. Through the movability of the guide rods 16 and the guide holes, the movable plate 10 is effectively limited and guided, thereby ensuring the stability of the movable plate 10 during the up and down movement process.

[0028] A base 17 is fixed to the bottom of the fixing column 1, and a plurality of mounting holes 18 are opened on the base 17. A decorative light is installed on the top of the fixing column 1. The base 17 and the mounting holes 18 facilitate fixing the bridge railing at a suitable position of the bridge.

[0029] Example:

[0030] In the initial state, the positioning rod 11 is located inside the through hole close to the inner cavity of the crossbar 2, and the end of the connecting rope 14 away from the extrusion plate 12 is wound around the rotating shaft 8;

[0031] When in use, first adjust the two ends of the cross bar 2 to be respectively inserted into the inner sides of the U-shaped blocks 3 at the corresponding positions on the two adjacent fixing columns 1, and insert the insert block 4 into the slot 7 on the cross bar 2;

[0032] Then, the knob 19 is turned to drive the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 drives the screw rod 9 to rotate, and at the same time, the connecting rope 14 wound on the rotating shaft 8 is released;

[0033] During the rotation of the screw rod 9, the screw rod 9 and the movable plate 10 cooperate with each other through the threads, and the guide rod 16 and the guide hole, so as to drive the movable plate 10 to move downward stably. Combined with the hinged effect at both ends of the connecting arm 13, as the connecting rope 14 is released, the extrusion plate 12 is extruded in the direction away from the screw rod 9. As the extrusion plate 12 is pushed, the positioning rod 11 is extruded outward until the positioning rod 11 passes through the positioning hole 5 on the plug block 4 and is inserted into the corresponding positioning groove 6 on the fixed column 1, so that the fixed column 1, the cross bar 2 and the plug block 4 are plugged and fixed together, without the need for welding or bolting for fixing, which saves time and effort, realizes the rapid installation and fixation of the cross bar 2, and then achieves the purpose of rapid installation of the bridge railing, and effectively improves the installation efficiency of the bridge guardrail.

[0034] Similarly, after all the crossbars 2 are installed, the installed bridge railings are fixed at a suitable position of the bridge through the base 17 and the mounting holes 18;

[0035] When the crossbar 2 needs to be maintained or replaced later, the knob 19 only needs to be rotated in the reverse direction to drive the rotating shaft 8 to rotate and reel in the connecting rope 14;

[0036] As the rotating shaft 8 rotates, the screw rod 9 is adjusted to rotate synchronously, driving the movable plate 10 to move upward. Combined with the hinged action at both ends of the connecting arm 13, as the connecting rope 14 is wound, the extrusion plate 12 is pulled toward the screw rod 9, thereby driving the positioning rod 11 to move toward the inner cavity of the cross bar 2 until the positioning rod 11 is away from the positioning groove 6 and the positioning hole 5. At this time, the cross bar 2 is adjusted upward away from the U-shaped block 3 to achieve rapid disassembly of the cross bar 2, which effectively improves the flexibility and practicality of the bridge railing and facilitates use.

[0037] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects.

[0038] All technical features in this embodiment can be freely combined according to actual needs.
