[0020] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] The following combination Figures 1 to 3 The utility model is described in detail.

[0022] A bridge-building machine safety protection system includes a bridge pier 1, a bridge-building machine 2 is arranged on the top of the bridge pier 1, a movable platform 201 is arranged in the middle of the bridge-building machine 2, a guardrail 202 is connected to the top edge of the movable platform 201, hinge blocks 205 are arranged at both ends of the bottom of one side of the guardrail 202, a support plate 204 is connected to the middle of the hinge block 205, a deflection groove 203 is provided on one side of the guardrail 202, a stabilizing component is connected between the support plate 204 and the deflection groove 203, one end of the stabilizing component slides along the support plate 204, and one end of the stabilizing component is hinged to the deflection groove 203.

[0023] First, the bridge-building machine 2 is gradually built on the bridge pier 1 according to needs, and then the bridge is built by the bridge-building machine 2. At the same time, a movable platform 201 is set in the middle of the bridge-building machine 2 to allow construction workers to move around, and then the guardrail 202 is used to provide safety protection for the construction workers.

[0024] Furthermore, the support plate 204 is hingedly connected to the hinge block 205 , and the support plate 204 also includes a slide groove 2041 and a hinge groove 2042 . The slide groove 2041 is arranged on the top of the support plate 204 , and the hinge groove 2042 is arranged on both sides of the inner wall of the support plate 204 .

[0025] At the same time, when installing the guardrail 202, by controlling the force applied to the support plate 204, the support plate 204 will be deflected along the hinge block 205, deflecting 90 degrees to one side of the guardrail 202, so that the guardrail 202 can be directly placed on the movable platform 201 through the support plate 204.

[0026] Furthermore, the stabilization component includes a deflection rod 2031, a retraction rod 2032 and a sliding hinge shaft 2033. The deflection rod 2031 is connected to the deflection groove 203, the retraction rod 2032 is arranged in the middle of the deflection rod 2031, and the sliding hinge shaft 2033 is arranged on both sides of one end of the deflection rod 2031. The end of the deflection rod 2031 away from the sliding hinge shaft 2033 is hingedly connected to the top of the middle of the deflection groove 203, and the sliding hinge shaft 2033 cooperates with the hinge groove 2042. The hinge groove 2042 is a long strip-shaped groove on both sides of the inner wall of the slide groove 2041.

[0027] Then, when the support plate 204 deflects, the deflection rod 2031 will be pulled out of the deflection groove 203 through the cooperation between the hinge groove 2042 on the inner wall of the top slide groove 2041 and the sliding hinge shaft 2033, so that the deflection rod 2031 will be deflected. At the same time, the sliding hinge shaft 2033 will slide in the hinge groove 2042 to cooperate with the deflection angle of the deflection rod 2031. At the same time, the deflection rod 2031 will also extend and retract through the retraction rod 2032 to cooperate with the deflection angle of the retraction rod 2032, so that the retraction rod 2032 will form an inclined support, forming a triangular support with the guardrail 202 and the support plate 204, thereby increasing its stability and allowing it to simply and firmly place the guardrail 202, and then directly perform fixing connections such as bolts, without the need for manual support during installation, which increases the risk of working at heights.

[0028] The following is a specific implementation process of the present invention. First, the bridge-building machine 2 is gradually built onto the bridge pier 1 according to needs, and then the bridge is built by the bridge-building machine 2. At the same time, a movable platform 201 is set in the middle of the bridge-building machine 2 to allow construction workers to move, and then the guardrail 202 is used to provide safety protection for the construction workers. At the same time, when installing the guardrail 202, the support plate 204 is controlled by applying force so that the support plate 204 is deflected along the hinge block 205 and deflected 90 degrees to one side of the guardrail 202, so that the guardrail 202 can be directly placed on the movable platform 201 through the support plate 204. Then, when the support plate 204 is deflected, the hinge groove 2042 on the inner wall of the top slide 2041 is connected to the sliding hinge shaft 20 33, the deflection rod 2031 will be pulled out of the deflection slot 203, and the sliding hinge shaft 2033 will slide in the hinge slot 2042 to cooperate with the deflection angle of the deflection rod 2031. At the same time, the deflection rod 2031 will also extend and retract through the retraction rod 2032 to cooperate with the deflection angle of the retraction rod 2032, so that the retraction rod 2032 will form an inclined support, forming a triangular support with the guardrail 202 and the support plate 204, thereby increasing its stability and allowing it to simply and firmly place the guardrail 202, and then directly perform fixing connections such as bolts, without the need for manual support during installation, which increases the risk of working at heights.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
