Description

Technical Field

[0001] The utility model relates to the technical field of beam-arch combination bridges, in particular to a continuous beam-arch combination bridge which is convenient for detection and maintenance. Background Art

[0002] A beam-arch bridge is a bridge whose primary load-bearing components are constructed from two independent structural systems, such as an arch-beam combination, a beam-truss combination, or a cable-beam combination. These systems can be statically determinate or indeterminate, thrust-free or thrust-supported, and their components can be made of the same or different materials. Currently, some bridges have relatively large spans, so continuous beam-arch bridges are used to increase their length.

[0003] However, the increase in length also brings troubles in inspection and maintenance. Due to the long length of the bridge itself, the existing method of inspecting and maintaining the bottom of the bridge is to lower the inspector down with a safety rope. When the inspector's position is changed, the inspector needs to be pulled up and then lowered down again after the position is changed. This not only reduces the efficiency of beam and arch inspection and maintenance, but also cannot guarantee the safety of the inspector.

[0004] Therefore, it is necessary to invent a continuous beam-arch combination bridge that is easy to detect and maintain to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a continuous beam-arch combination bridge that is easy to inspect and maintain, so as to solve the problem in the above-mentioned background technology that the efficiency of beam-arch inspection and maintenance is reduced while the safety of inspection personnel cannot be guaranteed.

[0052] The sliding hanging basket 500 is slidably installed on the top of the sliding hanger 400.

[0053] The construction workers descend from the bridge 100 onto the sliding hanger 400 and walk into the interior of the sliding basket 500. When the construction workers need to move forward and backward, a force is applied to the sliding basket 500 to move forward and backward, so that the basket 500 moves along the sliding hanger 400 under the action of the external force. When the construction workers need to move left and right, a force is applied to the sliding basket 500 to move left and right, so that the sliding basket 500 drives the sliding hanger 400 to move left and right along the guide assembly 300.

[0054] The sliding hanger 400 is provided to drive the sliding basket 500 to move, and the position of the sliding basket 500 is changed, so that the sliding basket 500 can drive the construction workers to move to any position at the bottom of the bridge 100, while ensuring the safety of the construction workers. When changing positions, the construction workers do not need to rise above the bridge 100 to move, thereby improving the efficiency of beam arch inspection and maintenance.

[0055] The bridge 100 is supported by the provision of the supporting piers 200 , and it is convenient for construction workers to apply force to the sliding hanging basket 500 to move in the left and right directions.

[0056] In some embodiments of the present invention, the guide assembly 300 includes:

[0057] A U-shaped frame 310 , wherein the U-shaped frame 310 is fixed to the bottom of the bridge 100 ;

[0058] The guide rod 320 has two ends fixedly connected to the inner walls of both sides of the U-shaped frame 310.

[0059] The U-shaped frame 310 ensures that the guide rod 320 is properly installed and fixed, and ensures the stability of the sliding hanger 400, thereby preventing the sliding hanger 400 from falling under the action of weight.

[0060] The guide rod 320 is provided to guide the sliding of the sliding hanger 400 , thereby preventing the sliding hanger 400 from deflecting during the sliding process.

[0061] In some embodiments of the present invention, the sliding hanger 400 includes:

[0062] A sliding sleeve 410 slidably sleeved on the outer side of the guide rod 320 ;

[0063] A plurality of first balls 420 are provided and fixed in an annular array inside the sliding sleeve 410 and in contact with the guide rod 320;

[0064] The hanging plate 430 is fixed to the bottom of the sliding sleeve 410 .

[0065] The sliding sleeve 410 cooperates with the guide rod 320 and drives the hanging plate 430 to slide along the guide rod 320;

[0066] The friction between the sliding sleeve 410 and the guide rod 320 is reduced by disposing the first ball 420 .

[0067] In some embodiments of the present invention, the sliding hanger 400 further includes:

[0068] Sliding floor 440, the top ends of the sliding floor 440 are respectively fixedly connected to the two hanging plates 430;

[0069] A sliding guide groove 450 is provided on the top of the sliding floor 440;

[0070] The footrest 460 is located at the front end of the sliding floor 440 .

[0071] When the sliding basket 500 is subjected to a force in the left and right directions, it will drive the sliding floor 440 to move in the left and right directions synchronously, so that the sliding floor 440 drives the sliding sleeve 410 to slide along the guide rod 320;

[0072] The sliding floor 440 is lifted by the setting of the hanging plate 430, and the height of the sliding floor 440 is ensured so that the sliding floor 440 can ensure the standing of the construction workers;

[0078] The second ball bearing 530 is rotatably mounted on the bottom of the construction protection basket 510 and contacts the top of the sliding floor 440 .

[0079] The provision of the construction protection basket 510 facilitates the entry of construction workers and provides protection for the construction workers, thereby increasing their safety.

[0080] The slider 520 ensures the normal installation of the construction protection basket 510 and cooperates with the sliding guide groove 450 to prevent the construction protection basket 510 from deflecting when sliding.

[0081] Among them, the coordinated arrangement of the first ball 420 and the second ball 530 can reduce the friction between the construction guard basket 510 and the sliding sleeve 410 during sliding, reduce the pulling force required for the construction guard basket 510 and the sliding sleeve 410 to slide, and improve the flexibility of the construction guard basket 510 and the sliding sleeve 410.

[0082] In some embodiments of the present invention, the sliding basket 500 further includes:

[0083] Two first sockets 540 are provided and are fixed on the two hanging plates 430 respectively;

[0085] Pull ropes 560 , four of which are respectively fixed on the first socket 540 and the second socket 550 , and extend into the interior of the construction protection basket 510 .

[0086] When a pulling force is applied to the pull rope 560 connected to the first socket 540, the pull rope 560 drives the construction protection basket 510 to slide forward and backward along the sliding guide groove 450. When a pulling force is applied to the pull rope 560 connected to the second socket 550, the pull rope 560 drives the construction protection basket 510 and the sliding hanger 400 to slide along the guide rod 320.

[0087] The pull rope 560 is fixed by the cooperation of the first socket 540 and the second socket 550, and when a pulling force is applied to the pull rope 560, the construction workers can be driven to change their positions.

[0088] Among them, the setting of the pull rope 560 can drive the construction protection basket 510 to move by contraction, and the position of the construction protection basket 510 can be moved by pulling four different pull ropes 560.

[0089] In some embodiments of the present invention, an arch beam 210 is fixedly installed between two supporting piers 200 , a plurality of steel cables 220 are fixedly installed on the arch beam 210 , and one end of the steel cables 220 away from the arch beam 210 is fixed to the bridge 100 .

[0090] The provision of the steel cables 220 and the arch beams 210 increases the robustness of the bridge 100 .

[0091] Working method of the utility model:

[0092] Step 1: The construction worker descends onto the foot pedal 460 and walks into the construction protection basket 510;

[0093] Step 2: When moving left and right to change position, tension is applied to the pull rope 560 connected to the second socket 550, and the pull rope 560 drives the construction protection basket 510 and the sliding hanger 400 to slide left and right along the guide rod 320 to change position;

[0094] Step 3: When the position is changed by moving forward and backward, tension is applied to the pull rope 560 connected to the first socket 540 , and the pull rope 560 will drive the construction protection basket 510 to slide forward and backward along the sliding guide groove 450 .
