[0040] Example 1
[0041] This embodiment discloses a bridge construction protection device. This device utilizes the cooperation between a threaded rod 3, a first threaded sleeve 4, a second threaded sleeve 15, a pin 11, a positioning groove 12, an insert rod 16, a sleeve 17, a clamping plate 6, a support plate 2, and extended guardrail plates 10. By rotating the threaded rod 3, the clamping plate 6 moves upward and clamps the bridge surface with the support plate 2. Simultaneously, as the clamping plate 6 moves upward, the two extended guardrail plates 10 extend to both sides, expanding the protective area. This main guardrail mounting frame 1 can be quickly installed at the edge of the bridge, greatly saving installation time and labor costs, and avoiding potential safety hazards caused by untimely guardrail installation. Specifically, the bridge construction protection device in this embodiment includes: a main guardrail mounting frame 1, a support plate 2, a threaded rod 3, a first threaded sleeve 4, a horizontal plate 5, a clamping plate 6, and a turntable 21.
[0042] The threaded rod 3 is located at the axis of symmetry of the main guardrail mounting frame 1;
[0043] like Figure 1 One end of the threaded rod 3 passes through the internal cavity of the main guardrail mounting frame 1 and is connected to the second threaded sleeve 15 located inside the main guardrail mounting frame 1, and is fixedly connected to the turntable 21 located at the top of the main guardrail mounting frame 1.
[0044] The other end of the threaded rod 3 is bolted to the first threaded sleeve 4 located at the center of the crossbar 5.
[0045] The bottom of the main guardrail mounting frame 1 is equipped with multiple support plates 2 that are compatible with multiple clamping plates 6 on the horizontal plate 5. In this embodiment, the side of the support plate 2 and clamping plate 6 that contacts the bridge is made of rubber, which can generate a large friction force. This allows the support plate 2 and clamping plate 6 to maintain a stable position when in contact with the bridge, and at the same time, it can adapt to the unevenness of the bridge surface.
[0046] Specifically: In this embodiment, the bottom of the main guardrail mounting frame 1 is rotatably connected to a threaded rod 3 via a bearing component; in addition, positioning rods 7 are fixedly connected to both sides of the bottom of the main guardrail mounting frame 1, with one end of the positioning rod 7 penetrating through the horizontal plate 5 and extending to the bottom of the horizontal plate 5.
[0047] like Figure 2 As an improved implementation, the bridge construction protection device also includes: an extended guardrail 10 and a pin 11;
[0048] The extension guardrail plate 10 is set in the cavity inside the main guardrail mounting frame 1 and is inserted into the main guardrail mounting frame 1.
[0049] A pin 11 is inserted into the top of the main guardrail mounting frame 1 through an opening. One end of the pin 11 passes through the main guardrail mounting frame 1 and extends into the interior of the main guardrail mounting frame 1. Several positioning grooves 12 are provided on the top of the extended guardrail plate 10 inside the main guardrail mounting frame 1 to cooperate with the pin 11.
[0050] The extended guardrail plate 10 is disposed in the internal cavity of the main guardrail mounting frame 1 and is slidably connected to the main guardrail mounting frame 1, specifically as follows:
[0051] A first sliding groove 8 is provided inside the top plate of the main guardrail mounting frame 1;
[0052] The first slider 9 is slidably installed inside the first slide groove 8, and the bottom of the first slider 9 is fixedly connected to the extension guardrail 10 by a connecting block.
[0053] Furthermore, insert rods 16 are fixedly connected to both sides of the second threaded sleeve 15, and sleeves 17 that cooperate with the insert rods 16 are fixedly connected to the opposite sides of the two extended guardrail plates 10 through connecting blocks. When the extended guardrail plate 10 is completely retracted into the main guardrail mounting frame 1, the insert rods 16 are inserted into the sleeves 17 to fix the extended guardrail plate 10 in the main guardrail mounting frame 1.
[0054] like Figure 3 As an improved implementation, the bridge construction protection device also includes warning components;
[0055] The warning component consists of a second slide 13, a second slider 14, a lifting plate 18, a vertical rod 19, and a warning plate 20;
[0056] One end of the lifting plate 18, which is placed horizontally away from the bridge, passes through the main guardrail mounting frame 1 and is fixedly connected to the second threaded sleeve 15.
[0057] A second slide groove 13 is provided on the surface of the main guardrail mounting frame 1 near the bridge side, which is used in conjunction with the lifting plate 18; the second slide block 14 is fixedly connected to the second threaded sleeve 15 in the second slide groove 13.
[0058] A vertical rod 19 is fixedly connected to the other end of the lifting plate 18, and a warning plate 20 is connected to the top of the vertical rod 19 via a connecting block. In practical applications, the warning plate 20 is made of eye-catching colors and reflective materials, and can be used for corresponding warning publicity by replacing the warning plate 20.
[0059] To make the bridge construction protection device more stable and secure during use, in this embodiment, a counterweight placement plate 25 is connected to one end of the support plate 2 near the bridge.
[0060] As an improved implementation, a turntable 21 is fixedly connected to one end of the threaded rod 3 and above the main guardrail mounting frame 1, and a handle 22 is fixedly connected to the top of the turntable 21.
[0061] Furthermore, in this embodiment, a limiting rod 23 is inserted into the top of the turntable 21 through an opening, and one end of the limiting rod 23 passes through the turntable 21 and extends to the bottom of the turntable 21;
[0062] like Figure 4-5 The top of the main guardrail mounting frame 1 is provided with grooves 24 that are equidistantly arranged in a ring shape to cooperate with the limiting rod 23.
[0063] During operation, the bridge construction protection device is placed on the bridge surface at the edge of the bridge via the support plate 2. Turning the handle 22 causes the threaded rod 3 to rotate. The rotation of the threaded rod 3 causes the clamping plate 6 to move upward through the first threaded sleeve 4 and contact the bottom of the bridge for fixation. At the same time, the rotation of the threaded rod 3 causes the second threaded sleeve 15 to move upward. The second threaded sleeve 15 disengages from the sleeve 17, lifts the pin 11 upward, and pulls outward the extension guardrail 10. The extension guardrail 10 moves to the designated position, and the pin 11 is inserted into the positioning groove 12 to fix the extension guardrail 10. The upward movement of the second threaded sleeve 15 causes the lifting plate 18 to move upward, so that the lifting plate 18 can drive the warning plate 20 to move upward through the vertical rod 19. The installation of the bridge construction protection device and the warning publicity are synchronized.
[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
