[0003] The current temporary protective structure for bridge construction is fixed by welding steel frames. In order to improve the stability of the support, there are diagonal bracing arms on both sides. However, the welding fixation results in the diagonal bracing arms occupying a lot of space, making it inconvenient to store and transport, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a temporary protective structure for bridge construction, which effectively solves the deficiencies of the prior art.

Several blocking crossbars are fixedly connected between the two columns. A lifting seat is slidably connected to the inner wall of each guide groove. A connecting groove is formed at the center of each side of the lifting seat. An inclined support arm is rotatably connected to the center of the inner wall of each connecting groove. A linkage rod is rotatably connected to both sides of the bottom of the inner wall of each guide groove. The middle of the inclined support arm is rotatably connected to the end of the linkage rod furthest from the column. An anti-slip support seat is rotatably connected to the bottom end of the inclined support arm. A fixed base is fixedly connected to the bottom end of each column.

[0009] The technical effect achieved by adopting the above solution is that, guided by the linkage rod, the inclined support arm can be opened outward and lowered, so that the anti-slip support seat presses against both sides of the ground, thereby achieving inclined support and improving the stability of the support.

By pushing the lifting seat downward and guiding it through the linkage rod, the inclined support arm can be opened outward and lowered, so that the anti-slip support seat presses against the ground on both sides to achieve inclined support and improve the stability of the support. At the same time, by pulling the lifting seat upward, the inclined support arm can be moved upward and guided by the linkage rod to rotate and move closer to the column, so that it can be retracted, reducing the space occupied on both sides and facilitating storage and transportation.

[0018] 2.

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] like Figures 1 to 3 As shown, a temporary protective structure for bridge construction includes two columns 2. Each column 2 has a guide groove in the center of its surface. A drive screw 4 is rotatably connected to the center of the inner wall of each guide groove. Several blocking crossbars 3 are fixedly connected between the two columns 2. A lifting seat 7 is slidably connected to the inner wall of each guide groove. A connecting groove 12 is formed in the center of both sides of the lifting seat 7. An inclined support arm 8 is rotatably connected to the center of the inner wall of each connecting groove 12. A linkage rod 6 is rotatably connected to both sides of the bottom of the inner wall of each guide groove. The middle of the inclined support arm 8 is rotatably connected to the end of the linkage rod 6 away from the column 2. An anti-slip support seat 9 is rotatably connected to the bottom end of the inclined support arm 8. A fixed base 1 is fixedly connected to the bottom end of each column 2.

[0025] As an optional technical solution of this utility model, a driven worm gear 5 is fixedly connected to the bottom of the drive screw 4, and a drive worm 10 is rotatably connected to one side of the bottom of the two columns 2. The two drive worms 10 are respectively inserted into the inner wall of the guide groove of the two columns 2 on both sides. The two sides of the drive worm 10 are respectively engaged with the two driven worm gears 5. A rotating head 11 is fixedly connected to the middle of the drive worm 10. By rotating the drive worm 10, the two driven worm gears 5 can be driven to rotate synchronously at the same time, thereby driving the lifting seats 7 on the inner wall of the guide groove of the two columns 2 to rise and fall synchronously, which facilitates the adjustment operation without the need for separate rotation adjustment.

[0026] As an optional technical solution of this utility model, the width of the inclined support arm 8 is adapted to the distance between the inner wall of the linkage rod 6, the length of the linkage rod 6 is half of the inclined support arm 8, and the width of the inclined support arm 8 is adapted to the width of the inner wall of the connecting groove 12. Guided by the linkage rod 6, the inclined support arm 8 can be opened outward and lowered, so that the anti-slip support seat 9 presses against both sides of the ground to achieve inclined support and improve the stability of the support.

[0027] As an optional technical solution of this utility model, the length of the inclined support arm 8 is less than the height of the column 2. After the lifting seat 7 is fully raised, the bottom end of the inclined support arm 8 is at the top of the fixed base 1. The width of the anti-slip support seat 9 is adapted to the width of the fixed base 1 protruding from the column 2, so that the anti-slip support seat 9 can be completely retracted to the top of the fixed base 1.

[0028] As an optional technical solution of this utility model, the bottom surface of the anti-slip support 9 is fixedly connected with an anti-slip layer. The anti-slip layer on the bottom surface of the anti-slip support 9 has several anti-slip patterns. Through the anti-slip layer and several anti-slip patterns, the road surface can be effectively supported after contact with the road surface, improving the stability of the support and preventing slippage.

[0029] As an optional technical solution of this utility model, the distribution height of the several blocking crossbars 3 is adapted to the height of the column 2, and the outer wall of the several blocking crossbars 3 is coated with a reflective coating, so that the blocking crossbars 3 provide effective blocking protection, and the reflective coating helps to warn vehicles at night.

[0030] The temporary protective structure used during bridge construction requires the following steps:

[0031] 1) Install the column 2 vertically to the edge of the construction location using the fixed base 1;

[0032] 2) Then, by rotating the drive worm 10, the two driven worm wheels 5 can be driven to rotate synchronously, thereby driving the lifting seats 7 on the inner wall of the guide groove of the two columns 2 to rise and fall synchronously.

[0033] 3) By pushing the lifting seat 7 downward and guiding it through the linkage rod 6, the inclined support arm 8 can be opened outward and lowered, so that the anti-slip support seat 9 presses against both sides of the ground to achieve inclined support and improve the stability of the support.

[0034] 4) By pulling up the lifting seat 7, the inclined support arm 8 can be moved upward and guided by the linkage rod 6 to rotate and approach the column 2, so that it can be retracted, reducing the space occupied on both sides and facilitating storage and transportation.

[0035] In summary, rotating the drive screw 4 causes the lifting seat 7 to slide up and down on the inner wall of the guide groove of the column 2. Pushing the lifting seat 7 downward and guiding it through the linkage rod 6 allows the inclined support arm 8 to open outward and fall, causing the anti-slip support seat 9 to press against both sides of the ground, achieving inclined support and improving the stability of the support. At the same time, pulling the lifting seat 7 upward allows the inclined support arm 8 to move upward and, guided by the linkage rod 6, rotate closer to the column 2, causing it to retract, reducing the space occupied on both sides and facilitating storage and transportation. Rotating the drive worm gear 10 simultaneously drives the two driven worm wheels 5 to rotate synchronously, thereby driving the lifting seats 7 on the inner walls of the guide grooves of the two columns 2 to rise and fall synchronously, facilitating adjustment operations without the need for separate rotation adjustments.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
