Description

Technical Field

[0001] The invention relates to the technical field of bridge hoisting equipment, and in particular to a device for assisting in hoisting a prefabricated cap beam of an assembled bridge. Background Art

[0002] An assembled bridge refers to a bridge whose superstructure is composed of prefabricated components. A cap beam refers to a beam installed on top of a pile pier to support, distribute and transfer the load of the superstructure. It is also called a cap beam. A reinforced concrete or lightly reinforced concrete beam is installed on the pier or on the piles. Its main function is to support the superstructure of the bridge and transfer all loads to the lower structure. Some piles are directly connected to the cap beam, while others are connected to the columns before connecting to the cap beam. In order to quickly and accurately complete the hoisting of the prefabricated cap beam, and at the same time make the prefabricated cap beam evenly stressed during the hoisting process, reduce stress concentration, and reduce the risk of component damage, the present invention proposes a device for assisting the hoisting of the prefabricated cap beam of an assembled bridge.

[0003] According to the search, the Chinese patent document, announcement number: CN220745069U, discloses a device for assisting the lifting of prefabricated cap beams of assembled bridges. Through the cooperation of slide grooves, sliders, connecting rods, limit frames, limit holes, adjusting rods, limit plates, second bearings, threaded holes, positive and negative threaded rods and rotating motors, the device can not only fix the prefabricated cap beams of the main body length, but also greatly increase the fixing effect of the device on the prefabricated cap beams, thereby greatly increasing the practicality of the equipment. The cooperation of the first cap beam anti-skid pad, the second cap beam anti-skid pad and the anti-skid protrusions can make the prefabricated cap beam more stable. However, in actual use, the device can only clamp and fix prefabricated beams of different models, and cannot drive them to move to the installed position, which reduces the overall practicality. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a device for assisting in the lifting of prefabricated cap beams of assembled bridges, which has the advantages of simple operation, stable installation, and improved work efficiency, and solves the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for assisting in lifting prefabricated cap beams of assembled bridges, comprising a traveling frame, a driving motor is fixedly installed on the front side of the traveling frame, a limiting slide groove is provided inside the traveling frame, a threaded rod and a slider are installed inside the limiting slide groove, a synchronous wheel is fixedly installed on the bottom end of the threaded rod, a crossbeam is fixedly installed on the inner side of the slider, a first cylinder is fixedly installed on the top surface of the crossbeam, a connecting rod is fixedly connected to the output shaft of the first cylinder, a base is fixedly installed on the bottom end of the connecting rod, a limiting rod and a second cylinder are fixedly installed on the top surface of the base, and a pressure plate is fixedly connected to the output shaft of the second cylinder.

[0008] Preferably, the number of the traveling frame, the limiting slide groove, the threaded rod and the slider is set to two, and the output shaft of the driving motor is fixedly connected to the front end of one of the threaded rods, and the two sliders are respectively threadedly connected to the outer surfaces of the two threaded rods.

[0009] Through the above technical solution, when the drive motor is started, the output shaft of the drive motor can drive one of the threaded rods to rotate, and this threaded rod can then drive the corresponding slider to slide inside the carriage frame, thereby effectively driving the movement of parts such as beams, and then conveniently and efficiently moving prefabricated beams and other parts, thereby improving the overall working efficiency of the device.

[0010] Preferably, there are two synchronous wheels, and outer sides of the two synchronous wheels are connected with belts for transmission.

[0011] Through the above technical solution, when the driving motor drives one of the threaded rods to rotate, the threaded rod can drive one of the synchronous wheels to rotate together, and the synchronous wheel can drive the other synchronous wheel and the threaded rod to rotate together through the belt, thereby driving the crossbeam and other parts to move. The two synchronous wheels and belts effectively ensure the synchronous movement of the two threaded rods and parts such as the slider, thereby ensuring the normal operation of the entire device.

[0012] Preferably, the number of the first cylinder, the connecting rod and the base are all two.

[0013] Through the above technical solution, when the two first cylinders are started, the output shaft of the first cylinder can drive parts such as the connecting rod and the base to move in the vertical direction, and then can effectively drive parts such as prefabricated beams to perform lifting, erection and other operations, thereby improving the overall practicality of the device.

[0014] Preferably, there are two limit rods, and limit blocks are fixedly mounted on the outer sides of the two limit rods.

[0015] Through the above technical solution, when the first cylinder drives the base and other parts to move in the vertical direction, the two limit rods and the limit blocks on their outer sides can effectively limit the movement path and travel distance, which can not only further improve the overall stability of the device, but also effectively protect the safety of the second cylinder and other parts, thereby ensuring the normal operation of the entire device.

[0016] Preferably, the number of the second cylinder and the number of the pressure plate are both two.

[0017] Through the above technical solution, after the prefabricated beam is placed into the interior of the base, the second cylinder is started, and the output shaft of the second cylinder can drive the pressure plate to move and press and fix the prefabricated beam. The arrangement of parts such as the base and the pressure plate not only allows the staff to place the prefabricated beam conveniently and quickly, but is also suitable for beams of different models and lengths, thereby improving the overall work efficiency and practicality of the device.

[0018] Preferably, rubber pads are fixedly mounted on the inner bottom surface of the base and the bottom surface of the pressing plate.

[0019] Through the above technical solution, when the pressure plate presses and fixes the prefabricated beam, the rubber pads on both sides can not only increase the friction with the prefabricated beam, making its installation more stable, but also prevent damage to the outer surface of the beam body, thereby improving the overall practicality of the device.

[0020] Compared with the prior art, the present invention provides a device for assisting the hoisting of prefabricated cap beams of assembled bridges, which has the following beneficial effects:

[0021] 1. The present invention places the prefabricated beam into the interior of the base, and then starts the second cylinder. The output shaft of the second cylinder can drive the pressure plate to move and press the prefabricated beam to fix it. The arrangement of parts such as the base and the pressure plate can not only enable the staff to place the prefabricated beam conveniently and quickly, but also can be suitable for beams of different models and lengths, thereby improving the overall work efficiency and practicality of the device; then the two first cylinders are started, and the output shafts of the first cylinders can drive parts such as the connecting rod and the base to move in the vertical direction, thereby effectively driving parts such as the prefabricated beam to perform lifting and erection operations, while the two limit rods and the limit blocks on their outer sides can effectively limit their moving path and travel distance, thereby further improving the overall stability of the device, while also effectively protecting the safety of parts such as the second cylinder, thereby ensuring the normal operation of the device as a whole.

[0022] 2. The present invention starts the driving motor, and the output shaft of the driving motor can drive one of the threaded rods and the synchronous wheel to rotate together. The threaded rod can then drive the corresponding slider to slide inside the traveling frame. The synchronous wheel can drive the other synchronous wheel and the threaded rod to rotate together through the belt, and then drive the crossbeam and other parts to move. The two synchronous wheels and belts effectively ensure the synchronous movement of the two threaded rods and the slider and other parts, ensuring the normal operation of the entire device.
