[0031] It will be apparent to those skilled in the art that various modifications and variations may be made to the specific embodiments of the present invention without departing from the scope or spirit of the present invention. Other embodiments derived from the present invention will be apparent to those skilled in the art. The present application description and examples are merely exemplary.

[0032] The utility model provides a hydraulic rotating device for a beam transport vehicle, such as Figure 1-4 In a specific embodiment, the rotating device comprises: a turntable bottom plate 1 fixedly arranged on the main beam 9 of the beam transport vehicle, an axis column 2 is vertically arranged at the center of the turntable bottom plate 1, and a beam support 3 for supporting the segmental beam is rotatably sleeved on the axis column 2.

[0033] Along the length direction of the main beam 9 of the beam transport vehicle, a cylinder 4 is provided on one side of the beam support 3. One end of the cylinder 4 is fixedly connected to the main beam 9 of the beam transport vehicle, and the other end is connected to the side wall of the beam support 3, which is used to drive the beam support 3 to rotate. The segmental beam is placed on the beam support 3 and transported by the beam transport vehicle. During the transportation process, feeding the beam, and adjusting the position, the beam support 3 can be rotated to adjust a certain angle, thereby improving the transportation and installation efficiency of the segmental beam.

[0034] In a specific embodiment of the utility model, the support beam bracket 3 includes a turntable 31 and a bracket rod 32. In this embodiment, the turntable 31 is a square structure or a rectangular structure close to a square, and it is mainly a turntable structure surrounded by welded steel pipes. The turntable 31 is rotatably arranged on the axis column 2 at the axis center, and the two bracket rods 32 are respectively arranged on both sides of the turntable 31.

[0035] Furthermore, a fixing groove is provided on the opposite side of the support rod 32, and the edge of the rotating disk 31 can be inserted into the fixing groove and fixedly connected by a fixing member.

[0036] Furthermore, a slideway 5 is fixedly provided on the outer side wall of the support rod 32 near the oil cylinder 4. Figure 8 As shown, the slideway 5 is provided with a plurality of fixing holes 51 along the length direction of the support rod 32 for fixing the end of the oil cylinder 4. In this embodiment, three fixing holes 51 are provided on the slideway 5.

[0037] like Figure 6 As shown, one end of the oil cylinder 4 is connected to the main beam 9 of the beam transport vehicle through the oil cylinder hinge seat 7, the oil cylinder hinge seat 7 is fixed on the main beam 9 of the beam transport vehicle, and one end of the oil cylinder 4 is rotatably connected to the oil cylinder hinge seat 7 through a pin shaft. And the rotating surface of the oil cylinder 4 is parallel to the plane of the main beam 9 of the beam transport vehicle.

[0038] In addition, the other end of the oil cylinder 4 is nested in the slideway 5 through the slide seat 8, and the relative position of the slide seat 8 and the slideway 5 can be fixed by inserting a pin into the fixing hole 51. Figure 7 As shown, the other end of the oil cylinder 4 is rotatably connected with the slide 8 through a pin, and the slide 8 is nested in the slide 5 and can slide along the slide 5. At the same time, the slide 8 has a positioning hole, and after the positioning hole is matched with the fixing hole 51 on the slide 5, the slide 8 can be fixed on the slide 5 through a fixing piece such as a pin or a bolt, so that its relative position is fixed, which is convenient for driving the support beam bracket 3 to rotate when the oil cylinder 4 is extended or retracted.

[0039] In addition, when the support beam bracket 3 does not need to be rotated, the slide seat 8 can be fixed to the slideway 5 by fixing parts such as pins or bolts to prevent the support beam bracket 3 from rotating during transportation or other times when fixation is required.

[0040] Further, rubber pads 33 are provided on the upper sides of the ends of the support rods 32. The rubber pads 33 can play an anti-skid role, preventing the segment beam from sliding, tilting or falling on the support rods 32 during transportation.

[0041] In the specific implementation of the utility model, Figure 5 As shown, a plurality of stiffening ribs 6 are fixedly provided at the connection between the circumference of the axis column 2 and the turntable bottom plate 1. The stiffening ribs 6 are evenly arranged on the circumference of the axis column 2 to fix the axis column 2 and enhance the strength of the connection structure.

[0042] In the specific implementation of the utility model, Figure 5 As shown, a pad 11 is fixedly arranged around the turntable bottom plate 1, and grease is arranged on the pad 11. In this embodiment, the pad 11 is arranged to avoid friction between the bracket rod 32 and the turntable bottom plate 1, and the grease is also applied to reduce the friction coefficient during rotation and improve the flexibility of rotation.

[0043] Furthermore, the turntable bottom plate 1 is a square structure.

[0044] In addition, the pad 11 includes a plurality of rectangular pads and a plurality of triangular pads. The rectangular pads are respectively arranged near the middle positions of the four sides of the turntable bottom plate 1, and the right-angled sides of two adjacent rectangular pads are butted, and the two angles of butt are both 90°. The triangular pad is arranged at the butt angle of two adjacent rectangular pads.

[0045] During the use of the hydraulic rotating device for the beam transport vehicle provided by the utility model, when the slide seat 8 is fixed at different positions of the slideway 5, the beam support bracket can rotate at different angles. The details are as follows:

[0046] The oil cylinder 4 is in the extended state, and the beam support 3 is parallel to the main beam 9 of the beam transport vehicle. The slide 8 is connected to the first fixing hole 51 on the slideway 5 close to the oil cylinder 4, and the slide 8 and the slideway 5 are locked by the fixing parts. Then the oil cylinder 4 is retracted, and the beam support 3 rotates clockwise, and the maximum rotation angle of the beam support 3 is 30°.

[0047] The lock between the slide 8 and the slideway 5 is released, the oil cylinder 4 is extended, the slide 8 is slid forward and connected to the second fixing hole 51 on the slideway 5 through the fixing piece, and the slide 8 and the slideway 5 are locked. Then the oil cylinder 4 is retracted, the joist bracket 3 rotates clockwise, and the maximum rotation angle of the joist bracket 3 is 60°.

Then retract the oil cylinder 4, the joist bracket 3 rotates clockwise, and the maximum rotation angle of the joist bracket 3 is 90°

[0049] By fixing the slide seat 8 at different positions of the slideway 5, different rotation angles can be achieved, thereby improving the application range of the rotating device.

[0050] The above description is only an illustrative specific implementation of the present invention. Without departing from the concept and principle of the present invention, any equivalent changes and modifications made by those skilled in the art should fall within the scope of protection of the present invention.
