Description

Technical Field

[0001] This application relates to the field of bridge engineering technology, and in particular to a bridge erecting machine transfer bracket adapted to a beam transport vehicle. Background Technology

[0002] A transfer support is a device installed on a beam transport vehicle to support a bridge erecting machine.

[0003] The traditional bridge erecting machine transfer support of the beam transport vehicle is an inverted trapezoidal steel frame structure. Its structure is simple, inverted trapezoidal, and crudely designed. The various parts of the transfer support are connected by bolts, requiring a lot of manpower to assemble the transfer support.

[0004] The traditional transfer support installation process is complicated and the assembly time is long, which seriously reduces the construction efficiency. In addition, the transfer support does not provide stable support for the bridge erecting machine during transportation, so it needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a bridge erecting machine transfer bracket adapted to a beam transport vehicle, so as to improve the problem of low stability when using traditional transfer brackets to transport bridge erecting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bridge erecting machine transfer support adapted to a beam transport vehicle includes a spreader beam, a support pier, a heightening pile, and a base. The feature is that: a first locator is provided at both ends of the top of the spreader beam, a second locator is inserted at the upper end of the first locator, and both the first locator and the second locator are provided with a plurality of telescopic holes arranged sequentially in the vertical direction. The telescopic holes on the first locator and the second locator are used to insert a fixing column.

[0008] By adopting the above technical solution, the operator can adjust the length of the second positioner extending from the first positioner according to the height of the bridge erecting machine, and then insert the fixing column into the telescopic hole where the first and second positioners overlap, so that the first and second positioners at both ends of the spreader beam can control the bridge erecting machine. Even if there is an unexpected bump during the transportation process, the bridge erecting machine will remain stable on the spreader beam.

[0009] Furthermore, a positioning plate is provided at the bottom of the first positioner, and a rotary locking device is provided through the center of the positioning plate.

[0010] By adopting the above technical solution, after adjusting the distance between the first positioners at both ends of the spreader beam to a suitable position, the first positioner can be quickly and effortlessly fixed using a rotary locking device.

[0011] Furthermore, the upper end wall of the spreader beam is provided with a first locking hole, and the side wall of the first locking hole is provided with a clearance hole. The rotary locking device includes a locking rod inserted into the first locking hole, a locking block fixed on the outer side wall of the locking rod, and a fixing block fixed on the upper end of the locking rod. The spreader beam is provided with a clearance cavity that communicates with the first locking hole to allow the locking block to rotate.

[0012] By adopting the above technical solution, when using the rotary locking device, the locking rod and the locking block pass through the first locking hole and the clearance hole respectively. After rotating the rotary locking device, the locking block rotates into the clearance cavity, and the fixing block abuts against the upper surface of the spreader beam to achieve the purpose of fixing.

[0013] Furthermore, the outer wall of the locking rod is provided with a mounting ring groove, and a rubber ring is provided in the mounting ring groove that abuts against the inner wall of the first locking hole.

[0014] By adopting the above technical solution, when the locking rod enters the first locking hole, the rubber ring on the mounting ring groove abuts against the inner wall of the first locking hole, preventing the rotary locking device from rotating unexpectedly.

[0015] Furthermore, a rotating plate is provided on the outer wall of the fixed block.

[0016] By adopting the above technical solution, when it is necessary to rotate the rotary locking device to fix the first positioner, the rotating plate can be directly grasped for operation.

[0017] Furthermore, a board placement groove is recessed on the upper surface of the spreader beam, and a thick wooden board is placed inside the board placement groove.

[0018] By adopting the above technical solution, the board placement groove is used to place the thick wooden board. The concave design can prevent the thick wooden board from shifting significantly and slipping out of the spreader beam. The upper surface of the thick wooden board is slightly higher than the upper surface of the spreader beam. The thick wooden board can play a padding role between the spreader beam and the bridge erecting machine, avoiding friction caused by direct contact between the bridge erecting machine and the transfer support, which would cause mutual wear and significant losses. The thick wooden board can be easily replaced at any time, which is more cost-effective.

[0019] Furthermore, a moisture-proof block is provided at the bottom of the board placement groove, and the upper surface of the moisture-proof block abuts against the thick wooden board.

[0020] By adopting the above technical solution, the moisture-proof blocks are evenly distributed at the bottom of the board-laying trough, and thick wooden boards can be laid stably on top. When there is water in the board-laying trough, the moisture-proof blocks play a role in ventilation and moisture prevention, effectively isolating the water and the thick wooden boards, and preventing the thick wooden boards from rotting due to prolonged contact with water.

[0021] Furthermore, a drainage hole is provided through the side of the plate-laying groove.

[0022] By adopting the above technical solution, the water accumulated in the board placement trough can be discharged through the drainage holes on both sides of the board placement trough, avoiding the thick boards from rotting due to excessive water submerging the moisture-proof block and causing them to be soaked in water for a long time. The drainage holes can extend the service life of the thick boards.

[0023] Furthermore, the surface around the spreader beam is provided with rope openings.

[0024] By adopting the above technical solution, when moving the carrying pole beam, ropes can be tied to the rope openings around the carrying pole beam, and then the equipment can be used for hoisting. At the same time, when the carrying pole beam is moved manually, the rope openings can also be used as handles to facilitate the movement.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The spacing of the first positioners on both sides of the spreader beam can be adjusted according to the width of the bridge erecting machine, and the length of the second positioner extending out of the first positioner can be adjusted according to the height of the bridge erecting machine. The combination of the two can ensure that the bridge erecting machine is effectively fixed during transportation. Even if there is an unexpected bump, the bridge erecting machine will still be stably placed on the spreader beam without significant displacement, thus improving the stability of transportation.

[0027] 2. The rotary locking device at the bottom of the first locator replaces the commonly used bolts for fixing, making the operation simpler, easier, and faster. By holding the rotating plate and rotating it 90 degrees, the first locator can be fixed, saving the assembly time of the transfer bracket and effectively improving the transportation efficiency.

[0028] 3. Thick wooden planks are placed between the spreader beam and the bridge erecting machine to prevent mutual wear due to direct contact; the recessed plank placement trough is used to hold the thick planks and prevent them from slipping; the moisture-proof block effectively isolates the thick planks from water accumulation at the bottom of the placement trough; in addition, the designed drainage holes can drain water from the trough in time, preventing the thick planks from rotting due to long-term immersion in water, effectively extending the service life of the thick planks and saving costs.
