Description

Technical Field

[0001] This utility model relates to the field of construction technology of steel-concrete composite arch bridges, and in particular to an auxiliary device for turning over arch rib segments. Background Technology

[0002] Concrete-filled steel tube arch bridges are a common structural form in bridge engineering. They combine the advantages of steel tubes and concrete, possessing high bending stiffness and compressive strength, and are widely used in transportation construction fields such as highways and railways.

[0003] The construction of a steel-concrete composite arch bridge requires the installation of steel pipe arch ribs first, followed by filling the ribs with concrete. The arch ribs are divided into multiple prefabricated segments, which are typically moved to their designed positions and assembled using hoisting methods. At the hoisting site, the arch rib segments need to be flipped before being lifted vertically using hoisting ropes. During hoisting, to prevent the top and bottom of the arch rib segments from rubbing against the ground, two hoisting devices are used in combination. However, these devices occupy a large area, and in confined spaces, only one device is often permitted. Furthermore, a single device can only suspend the top of the arch rib segment, leaving other parts susceptible to friction with the ground. This can lead to damage to the arch rib coating and even deformation of the arch rib chords. Solving this problem is crucial for ensuring the quality of the arch ribs. Utility Model Content

[0004] This utility model discloses an auxiliary device for turning over arch rib segments, which can prevent the arch rib segments from contacting the ground during the turning process using only a single hoisting device, thereby effectively avoiding wear or even deformation caused by friction between the arch ribs and the ground.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An auxiliary device for turning over arch-rib segments includes:

[0007] Vehicle body structure;

[0008] The walking mechanism is rollingly connected to the bottom of the vehicle body mechanism;

[0009] A support tube, which is disposed on the vehicle body mechanism, includes a support tube body and a support tube connecting part. The support tube connecting part is connected to the bottom end of the support tube body and can be rotatably connected to the vehicle body mechanism in a vertical plane. The support tube body can be matched and inserted into the chord of the arch rib segment, or matched and sleeved on the periphery of the bottom end of the chord of the arch rib segment.

[0010] Preferably, the support tube connection is detachably connected to the vehicle body mechanism.

[0011] Preferably, the top surface of the vehicle body mechanism is connected to an ear plate, the support tube connection part is provided with a pin hole, and a pin shaft is matched and passed through the ear plate and the pin hole to connect the vehicle body mechanism and the support tube connection part together.

[0012] Preferably, the vehicle body structure includes a vehicle body crossbeam and a vehicle body longitudinal beam, wherein there are at least two vehicle body longitudinal beams arranged in parallel and connected at their tops by the vehicle body crossbeam.

[0013] Preferably, the top surface of the vehicle body beam is connected to an ear plate, the support tube connection part is provided with a pin hole, and a pin shaft is matched and passed through the ear plate and the pin hole to connect the vehicle body mechanism and the support tube connection part together.

[0014] Preferably, the walking mechanism includes rollers.

[0015] Preferably, the traveling mechanism includes rollers and roller shafts, with both ends of the roller shaft connected to the rollers via bearings, and the top surface fixedly connected to the top surface of the vehicle body longitudinal beam.

[0016] Preferably, the vehicle body crossbeam is made of double-beam I-beams.

[0017] In practical use, the above-described auxiliary device for turning over arch rib segments requires at least two auxiliary devices of this utility model to be matched for turning over an arch rib segment. The top of the arch rib segment is suspended by hoisting equipment and hoisting ropes. A pad is placed under the top of the arch rib segment. The support tube bodies of the two auxiliary devices are inserted into the two chords at the bottom, or the support tube bodies of the two auxiliary devices are respectively fitted around the outside. Then, the top of the arch rib segment is lifted upward by the hoisting equipment to turn it vertically. The auxiliary devices move forward with it, and the support tube bodies also rotate upward. After the vertical turning is in place, the arch rib segment can be separated from the auxiliary devices.

[0018] This utility model has the following advantages:

[0019] (1) By using the auxiliary device of this utility model, the chord always maintains a certain distance from the ground during the process of turning the arch rib segment. This effectively solves the problem that the chord is damaged or even deformed due to friction caused by contact with the ground when the arch rib can only be turned in a narrow space with a single hoisting device.

[0020] (2) The present invention is designed to connect the support tube and the chord of the arch rib segment by plugging in, which can better prevent the arch rib segment from detaching from the auxiliary device during the turning process. This can better ensure that the entire arch rib segment will not be worn or deformed by the ground friction during the vertical turning process. At the same time, it can also better prevent the arch rib segment from shaking when it is in an upright state, thus reducing safety risks. Attached Figure Description

[0030] An auxiliary device for turning over arch-rib segments, combined with Figure 1-3 As shown, the device includes a vehicle body mechanism 200, a traveling mechanism 100, and a support pipe 400. The vehicle body mechanism 200 is the main supporting structure of the device. The traveling mechanism 100 is rolled to the bottom of the vehicle body mechanism 200 and can drive the vehicle body mechanism 200 and its upper structure to move. The support pipe 400 is mounted on the vehicle body mechanism 200 and includes a support pipe body 402 and a support pipe connecting part 401. The support pipe connecting part 401 is connected to the bottom end of the support pipe body 402 and can be rotatably connected to the vehicle body mechanism 200 in a vertical plane. That is, the support pipe connecting part 401 can rotate in a vertical plane with the vehicle body mechanism 200 as a support point. The support pipe body 402 can be inserted into the chord of the arch rib segment 500 or fitted around the bottom end of the chord of the arch rib segment 500.

[0031] In practical application, taking a structure where the support tube body 402 can match the chord member inserted into the arch rib segment 500 as an example, such as... Figure 4-5 As shown, Figure 4 The diagram shows the preparatory state before the vertical turning of the arch rib segment. The top of the arch rib segment 500 (this top refers to the top of the arch rib segment 500 after installation) is suspended using hoisting equipment and a hoisting rope 700. The arch rib segment 500 is turned to a horizontal longitudinal position using the hoisting rope 700. A pad is placed under the top of the arch rib segment 500. Two support tube bodies 402 of the auxiliary device of this embodiment are inserted into the two chords at the bottom, ensuring that at least two auxiliary devices of this embodiment are used for turning one arch rib segment. The top of the arch rib segment 500 is lifted upwards by the hoisting equipment, causing it to turn vertically. The auxiliary devices move forward accordingly, and the support tube bodies 402 also rotate upwards. The turning is then complete. Figure 5As shown, by setting up the auxiliary device in this embodiment, the chord members always maintain a certain distance from the ground during the turning process of the arch rib segment 500. This effectively solves the problem of damage to the arch rib coating or even deformation of the arch rib chord members caused by friction from contact with the ground when the arch rib can only be turned in a narrow space with only a single hoisting device. Furthermore, this embodiment uses a plug-in connection between the support pipe 400 and the chord members of the arch rib segment 500, which can better prevent the arch rib segment 500 from detaching from the auxiliary device during the turning process. This better ensures that the entire arch rib segment 500 will not be worn or deformed by friction with the ground during the vertical turning process.

[0032] Preferably, the support tube connection part 401 is detachably connected to the vehicle body mechanism 200. By configuring it as a detachable connection, the auxiliary device of this embodiment can replace the support tube 400 according to the tube diameter of different bridge chords, so as to realize the reuse of the auxiliary device of this embodiment.

[0033] Preferably, this embodiment provides a structure in which the vehicle body mechanism 200 and the support tube connection part 401 are rotatably and detachably connected. The top surface of the vehicle body mechanism 200 is connected to an ear plate 300, which necessarily has an ear hole. The support tube connection part 401 is provided with a pin hole, and a pin is matched and passed through the ear plate 300 and the pin hole to connect the vehicle body mechanism 200 and the support tube connection part 401 together. The ear plate 300 has a simple structure and well meets the operational requirements of the support tube 400 being detachable and rotatable.

[0034] Preferably, this embodiment provides a specific vehicle body mechanism 200, which includes a vehicle body crossbeam 201 and a vehicle body longitudinal beam 202. There are at least two longitudinal beams 202, arranged in parallel, and connected at the top by the vehicle body crossbeam 201. This combined structure of the crossbeams 201 and longitudinal beams 202 allows the load of the arch rib segment 500 to be evenly transferred to the traveling mechanism 100, better ensuring the overall structural stability of the vehicle body mechanism 200 during the vertical turning of the arch rib segment 500. More preferably, to better ensure support strength, the vehicle body crossbeam 201 is made of double-beam I-beams, and the vehicle body longitudinal beam 202 is also made of I-beams. Based on the above vehicle body mechanism 200, the ear plate 300 is disposed on the top surface of the vehicle body crossbeam 201.

[0035] Preferably, this embodiment provides a specific walking mechanism 100, which includes rollers 101 that can effectively drive the structure on them to move. More preferably, based on the vehicle body mechanism 200 form that combines the vehicle body crossbeam 201 and the vehicle body longitudinal beam 202, the walking mechanism 100 includes rollers 101 and roller shafts 102. The two ends of the roller shaft 102 are connected to the rollers 101 through bearings, and the top surface is fixedly connected to the top surface of the vehicle body longitudinal beam 202. The combination of the vehicle body crossbeam 201 and the vehicle body longitudinal beam 202 can effectively prevent deformation of the roller shaft 102.
