Technical Field
[0001] The utility model relates to the technical field of side baffle bending, in particular to a road side baffle bending device capable of controlling the bending angle. Background Technique
[0002] A road side baffle refers to a protective facility set at the edge of a road or a construction site, usually made of materials such as metal or plastic, and is used to prevent vehicles or pedestrians from accidentally falling or slipping from the edge of the road. The main function of the roadside baffle is to provide traffic safety protection and prevent traffic accidents. In a specific road construction site, the roadside baffle is usually installed at the edge of the road to divide the construction area and the driving area to ensure the safety of construction workers and drivers. The road side baffle is usually composed of a support structure and a retaining plate. The support structure can fix the baffle at a fixed section, and the retaining plate can perform slope protection according to the shape of the road.
[0003] The baffle is transported to the road for installation after production. Generally, it is a long straight-section plate. However, there may be a curvature in some sections of the road. Therefore, it is necessary to bend the side baffle to adapt to the road curvature. Usually, a bending device is used. However, the existing bending devices can often only perform one-stage bending, that is, they cannot bend the two sides of the side baffle synchronously but to different degrees, resulting in large limitations in the bending position and bending angle and insufficient universality. For some road sections with complex curvatures where both sides of the side baffle need to be bent, repeated bending steps are required, which increases the bending workload and time.
[0004] Therefore, it is very necessary to invent a road side baffle bending device capable of controlling the bending angle to solve the above problems. Content of the Utility Model

One end of the cross bar close to the middle fixed abutting plate is connected with a screw rod that can slidably penetrate through the vertical seat. A rotary frame is threadedly sleeved on the end of the screw rod outside the vertical seat.
[0011] As a preferred solution of the present utility model, both the top end and the bottom end of the bend fixed abutting plate are connected with first side clamping strips.

The rotation angle between the linear movable abutment plate 10 and the bending movable abutment plate 11 is controllable. The middle fixed abutment plate 2, the linear fixed abutment plate 3, and the bending fixed abutment plate 4 are mainly used to position the side baffle on one side, and finally, through the propulsion and extrusion assembly, the side baffle is made to fit for complete bending operation.
[0023] On the side of the top surface of the bottom plate 1 away from the middle fixed abutment plate 2, there is a slide rail 6. The propulsion and extrusion assembly includes a slide block 7 that can slide along the slide rail 6, a mounting plate 8 provided at the top end of the slide block 7, and a telescopic member 9 installed on the side of the mounting plate 8 close to the middle fixed abutment plate 2.

There is a detachable connection between the top end of the mounting plate 8 and the top end of the linear fixed abutment plate 3 with a synchronous plate 12. The synchronous plate 12 is provided with a first guiding groove 13. The top end of the linear movable abutment plate 10 is provided with a slide bar 14 that can slide along the first guiding groove 13.

[0025] At the middle of the top surface of the middle fixed abutment plate 2, a vertical seat 22 is provided. At the top end of the middle moving abutment plate 5, a cross bar 24 is detachably installed. One end of the cross bar 24 close to the middle fixed abutment plate 2 is connected with a screw rod 23 that can slidably penetrate through the vertical seat 22. A rotary frame 28 is threadedly sleeved on the end of the screw rod 23 located outside the vertical seat 22. By changing the length of the screw rod 23 passing through the vertical seat 22, the distance between the middle moving abutment plate 5 and the middle fixed abutment plate 2 is adjusted to adapt to the thickness of the side baffle and clamp it. Finally, by tightening the rotary frame 28, the middle moving abutment plate 5 clamps and fixes the side baffle on the side of the middle fixed abutment plate 2.
[0026] At the top end and the bottom end of the bent fixed abutment plate 4, first side clamping strips 19 are respectively connected.

On one side of the top surface of the linear fixed abutment plate 3, a second positioning stud 20 is provided. The second positioning stud 20 longitudinally penetrates through the first side clamping strip 19, and a second nut 21 is threadedly sleeved on the part of the second positioning stud 20 located above the first side clamping strip 19. The two first side clamping strips 19 can drive the bent fixed abutment plate 4 to rotate between the linear fixed abutment plate 3, thereby adjusting the bending angle.
[0027] At the top end and the bottom end of the bent moving abutment plate 11, second side clamping strips 25 are respectively connected. One ends of the two second side clamping strips 25 are respectively in rotational abutment with the top surface and the bottom surface of the linear moving abutment plate 10. On one side of the top surface of the linear moving abutment plate 10, a third positioning stud 26 is provided. The third positioning stud 26 longitudinally penetrates through the second side clamping strip 25, and a third nut 27 is threadedly sleeved on the part of the third positioning stud 26 located above the second side clamping strip 25.
[0028] In the present utility model, by laterally sliding to change the positions of the two linear fixed abutting plates 3 on both sides of the middle fixed abutting plate 2, so as to adapt to the length of the linear part of the side baffle, that is, to change the positions of the bent fixed abutting plate 4 and the middle fixed abutting plate 2, that is, to change the rotation positions of the linear fixed abutting plate 3 and the bent fixed abutting plate 4, in order to adapt to the bending at different positions of the side baffle. By controlling the rotation angles of the bent fixed abutting plate 4 and the linear fixed abutting plate 3, the bending angle of the variable baffle can be adaptively changed. The middle fixed abutting plate 2, the linear fixed abutting plate 3 and the bent fixed abutting plate 4 are mainly used to position the side baffle on one side. During the actual bending process, since the linear moving abutting plate 10 slides synchronously with the linear fixed abutting plate 3, the positions of the linear moving abutting plate 10 and the linear fixed abutting plate 3 are synchronized, and the positions of the bent moving abutting plate 11 and the bent fixed abutting plate 4 are synchronized. Finally, by pushing the extrusion assembly to change the distance between the linear moving abutting plate 10 and the linear fixed abutting plate 3, the linear moving abutting plate 10 and the linear fixed abutting plate 3 clamp the side baffle therebetween, and the side baffle is made to fit the linear fixed abutting plate 3 and the bent fixed abutting plate 4 by the extrusion force of the linear moving abutting plate 10 and the bent moving abutting plate 11, thereby completing the bending of the side baffle. Moreover, the structures on both sides of the middle fixed abutting plate 2 are the same and can be carried out synchronously, so that in the present utility model, according to the degree of road bending, synchronous but different curvature bendings can be carried out at different length positions on both sides of the side baffle, reducing the limitations of the bending position and the bending angle, improving the universality, and avoiding repeated-step bending on both sides of the side baffle.
[0029] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
