DETAILED DESCRIPTION

[0018] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0020] The utility model will be described in detail below with reference to the accompanying drawings. Figure 1 to Figure 2 As shown: the temporary reinforcement device for road and bridge protection described in this embodiment includes a support base 2 fixed to the ground by a ground anchor 1, a rotatable support rod 3 hinged to the upper end of the support base 2 by a first hinge seat 61, a first adjusting screw rod 31 connected from the upper end to the inner side of the support rod 3, a rotatable U-shaped clamp 4 hinged to the end of the first adjusting screw rod 31 by a second hinge seat 62, and an adjustment limit mechanism 5 arranged on the U-shaped clamp 4, the outer side of an open end on one side of the U-shaped clamp 4 is hinged to the first adjusting screw rod 31, and the other open end is a free end.

[0021] The temporary reinforcement device for road and bridge protection described in this embodiment adopts a fully rigid mechanical connection. During construction, the reinforcement device is directly fixed to the ground through the ground anchor bolt 1. Installation, dismantling and lifting are extremely convenient, and it is easy to meet the force requirements. For different prefabricated road and bridge components 8, the size of the U-shaped clamp 4 can be adjusted by the adjustment limit mechanism 5, and the length of the first adjustment screw rod 31 can be adjusted by rotating the support rod 3, so as to meet the temporary reinforcement of any component, effectively improve the construction efficiency on site, and also improve the construction safety; in summary, the reinforcement device has a simple structure, is firm and reliable, and is flexible to install. It can be used directly after processing and manufacturing. It has low cost and is easy to standardize. It has outstanding results in construction efficiency, safe operation and economic benefits.

[0022] As a preferred implementation of the above technical solution, the support rod 3 is connected to the first articulated seat 61 through the first rotating seat 71, so that the support rod 3 can not only make a circular motion around the articulated seat to facilitate the connection and fixation of the road and bridge prefabricated component 8, but also rotate around the axis of the first rotating seat 71 to adjust the length of the first adjusting screw screwed out or screwed in to the support rod 3, thereby adjusting the overall length; similarly, the U-shaped clamp 4 is connected to the second articulated seat 62 through the second rotating seat 72, so that the U-shaped clamp 4 can not only make a circular motion around the articulated seat to ensure that the U-shaped clamp 4 can be fully clamped into the clamped part, but also rotate around the axis of the second rotating seat 72. After the U-shaped clamp 4 is rotated and adjusted to a horizontal position, it can easily pass through a smaller gap for clamping, thereby adapting to the temporary reinforcement of any component.

[0023] In order to facilitate adjustment and improve installation efficiency, as a further improvement of the above technical solution, a first adjustment handle 32 for manually rotating the support rod 3 is provided on the support rod 3.

[0024] As a preferred implementation of the above technical solution, the adjustment and limiting mechanism 5 includes a second adjustment screw rod 51 vertically inserted from the hinged side of the U-shaped clamp 4 and a second adjustment handle 52 arranged at the outer end of the second adjustment screw rod 51. The length of the second adjustment screw rod 51 inserted into the U-shaped clamp 4 is adjusted by rotating the second adjustment handle 52, thereby clamping prefabricated road and bridge components 8 of different sizes.

[0025] As a preferred implementation of the above technical solution, the inner end of the second adjusting screw rod 51 is also hinged with a buffer clamping plate 53, which can avoid damage to the surface of the road and bridge prefabricated component 8 caused by screwing in the second adjusting screw rod 51. The hinged structure enables it to adapt to the clamping of parts with different slopes.

[0026] As a preferred implementation of the above technical solution, both the first adjustment handle 32 and the second adjustment handle 52 are linear structures or disc-shaped structures.

[0027] As a preferred implementation of the above technical solution, the outer surface of the support rod 3 is provided with a reflective sticker (not shown in the figure), which can reflect the existing light when the light is dim to form a very eye-catching sign, thereby preventing people from tripping due to unclear vision.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
