Description

Technical Field

[0001] This utility model relates to the field of steel-concrete composite beam bridge construction technology, specifically to an integrated equipment for transporting and erecting precast bridge deck panels. Background Technology

[0002] The construction of steel-concrete composite beam bridge decks mainly includes cast-in-place and precast assembly methods. Cast-in-place methods involve erecting formwork and tying reinforcing bars on the steel beams before pouring concrete. While the construction technology is relatively mature, it has a long construction cycle, a large amount of on-site wet work, difficulty in quality control, and a significant environmental impact. Precast assembly methods involve prefabricating bridge decks in a prefabrication yard, then transporting them to the site for installation. Precast panels are wet-jointed and connected to the steel beams with shear studs. This method offers good installation adaptability and fast construction speed, but the precast bridge decks are large and heavy, requiring specialized transportation equipment and large lifting equipment or bridge erecting machines. The lifting equipment has high requirements, and the bridge erecting machines rely on rails for movement, resulting in lower efficiency. Utility Model Content

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] like Figs. 1-3 As shown, a precast bridge deck transport and erection integrated equipment includes a self-propelled transport device 6 for automatically driving the entire equipment. A first gantry-type rear support leg 3 and a second gantry-type rear support leg 14 are fixed parallel to each other at the top of the rear of the self-propelled transport device 6. Telescopic slide beams 2 are slidably mounted on the first gantry-type rear support leg 3 and the second gantry-type rear support leg 14. A lifting trolley 1 is slidably mounted on the top of the telescopic slide beam 2. A telescopic front support leg 4 is hinged to the head of the telescopic slide beam 2. A support seat 9 is installed at the end of the telescopic rod 11 of the telescopic front support leg 4. An inclined telescopic strut 5 is hinged between the telescopic front support leg 4 and the telescopic slide beam 2. This equipment enables integrated transport and installation of precast slabs, featuring a simple structure, convenient operation, good applicability, safety, reliability, and time and labor savings. During the specific construction process, the self-propelled transport device 6 is supported on top of the laid precast slab 7, and the precast slab 19 to be installed is stored on the self-propelled transport device 6. The self-propelled transport device 6 drives the entire equipment to move. After it moves to the installation position, the telescopic slide beam 2 extends and the telescopic front outrigger 4 unfolds, thereby supporting the support seat 9 on the steel beam 8. Then, the lifting trolley 1 is started to lower the lifting hook 16, and the precast slab stored on the self-propelled transport device 6 is lifted and installed.

[0028] Furthermore, the self-propelled transport device 6 includes a frame 23, with wheel axle motors 20 mounted on the four bottom corners of the frame 23 via wheel frames 22. Wheels 21 are mounted on the output shafts of the wheel axle motors 20. By employing the aforementioned self-propelled transport device 6, powered by an electric motor, fossil fuels are eliminated, reducing carbon emissions; and transportation efficiency is high. During operation, the wheel axle motors 20 drive the wheels 21, which then move and travel on top of the precast slab 7.

[0029] Furthermore, the wheel 21 is a tire wheel. By using tire wheels for travel, there is no need to lay tracks, and it is not limited by the site, thus enhancing adaptability.

[0030] Furthermore, drive wheels 15 are installed at the positions where the first gantry-type rear outrigger 3 and the second gantry-type rear outrigger 14 cooperate with the telescopic slide beam 2. The drive wheels 15 ensure that the telescopic slide beam 2 can slide on the top of the first gantry-type rear outrigger 3 and the second gantry-type rear outrigger 14, thereby controlling the extension or retraction of the telescopic slide beam 2. The drive wheels 15 are also connected to a remote control system, facilitating remote control.

[0031] Furthermore, a limiting plate 17 is fixed to the tail end of the telescopic slide beam 2. The limiting plate 17 effectively prevents the telescopic slide beam 2 from slipping, ensuring its safety.

[0032] Furthermore, a winch is installed on the lifting trolley 1, with a lifting hook 16 wound around it. A lifting plate 18 for lifting the precast slab 7 is connected to the lifting hook 16. The winch facilitates the subsequent lifting of the precast slab, thus aiding in its installation. Simultaneously, the lifting trolley 1 is connected to a remote control system, allowing for remote operation of the lifting trolley 1.

[0033] Furthermore, the telescopic front outrigger 4 is a hydraulic telescopic outrigger. The top of the cylinder of the hydraulic telescopic outrigger is hinged to the telescopic slide beam 2 via a first pin 13, and the end of the telescopic rod 11 of the hydraulic telescopic outrigger is connected to the support seat 9 via a hinge seat 10. The aforementioned hydraulic telescopic outrigger ensures reliable support for one end of the telescopic slide beam 2 during hoisting, preventing it from overturning. When hoisting operations are required, the telescopic front outrigger 4 is extended and supported on the top of the steel beam 8 via the support seat 9. Moreover, the telescopic front outrigger 4 is connected to a remote PLC control system, allowing for remote control of its extension and retraction.

[0034] Furthermore, the inclined telescopic support rod 5 is a hydraulic telescopic rod, with both ends of the hydraulic telescopic rod hinged to the outer walls of the telescopic front outrigger 4 and the telescopic sliding beam 2 respectively via a third pin 12. The aforementioned inclined telescopic support rod 5 facilitates the retraction and extension of the telescopic front outrigger 4. When not in use, the telescopic front outrigger 4 can be rotated and retracted; when in use, it can be rotated and extended. Moreover, the inclined telescopic support rod 5 is connected to a remote PLC control system, thereby enabling remote control of its telescopic movement.

[0035] Furthermore, the self-propelled transport device 6 is used to travel on top of the laid precast slabs 7, which are supported on top of the steel beams 8. The self-propelled transport device 6 stores precast slabs 19 to be installed. Through the above arrangement, the self-propelled transport device 6 can be effectively supported by the laid precast slabs 7.

[0036] The working process and principle of this utility model:

[0037] When it is necessary to install the precast slab 7, the precast slab 19 to be installed is placed on the self-propelled transport device 6. The self-propelled transport device 6 is then moved to the top of the precast slab 7, and the precast slab 19 to be installed is placed on the self-propelled transport device 6. The wheel 21 is driven by the wheel axle motor 20, and then the wheel 21 moves on the top of the precast slab 7. After it moves to the installation position, the telescopic sliding beam 2 is extended remotely. After it extends into place, the inclined telescopic support rod 5 is activated to rotate and unfold the telescopic front outrigger 4, and then the support seat 9 is supported on the steel beam 8. Then the lifting trolley 1 is activated to lower the lifting hook 16, and then the precast slab stored on the self-propelled transport device 6 is lifted and installed. After one precast slab is installed, the self-propelled transport device 6 is moved again to install the next precast slab.
