Technical Field

[0001] The utility model relates to the technical field of bridge construction protection, in particular to a bridge safety construction protection structure. Background Technique

[0002] During the process of bridge construction, in order to ensure the personal safety of construction workers, temporary guardrails are generally installed on both sides of the bridge. When installing the guardrails for bridge construction, embedded parts need to be installed on the construction bridge, generally embedded bolts. Installation holes are provided on the guardrails. After the guardrails are inserted on the embedded bolts, the guardrails are installed on the bridge by tightening nuts, so as to prevent workers from falling from the bridge during construction.

[0003] However, the existing guardrails for bridge construction need to be installed on the embedded parts through the cooperation of nuts, which not only has low installation efficiency, but also is more troublesome to disassemble later. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bridge safety construction protection structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A bridge safety construction protection structure includes: two support frames, a guardrail plate is fixedly connected between the two support frames, and fixing mechanisms are arranged on one side of the two support frames away from each other;

[0007] The fixing mechanism includes: a sleeve, the sleeve is fixedly connected to the lower part of the outer wall of the support frame, a clamping block one is fixedly connected to the inner wall of the sleeve, the outer wall of the sleeve is threadedly connected with a fixing bolt, and one end of the fixing bolt extends into the sleeve. The extended end of the fixing bolt is rotatably connected with a clamping block two. By rotating the fixing bolt, the clamping block two is driven to slide horizontally along the outer wall of the sliding rod, so that the clamping block two and the clamping block one are clamped and fixed on the embedded bolt, thereby fixing the support frame and the guardrail plate. This not only improves the working efficiency during installation, but also is more convenient to disassemble later, improving the practicability.

[0008] Preferably, a screw sleeve is embedded in the outer wall of the sleeve, and the fixing bolt is threadedly connected to the inner wall of the screw sleeve.

[0009] Preferably, the opposite surfaces of the clamping block one and the clamping block two are both arc-shaped, a sliding rod is fixedly connected to the inner wall of the sleeve, and the clamping block two is slidably connected to the outer wall of the sliding rod. By arranging the sliding rod to limit and guide the clamping block two, the clamping block two is prevented from rotating with the fixing bolt, so that the clamping block two slides horizontally along the outer wall of the sliding rod.

[0010] Preferably, the inside of the guardrail plate is hollow and the top is open. An extension plate is slidably connected to the inner wall of the guardrail plate. By providing the extension plate, the height and area of protection are increased.

[0011] Preferably, the inside of both of the support frames is hollow. An adjusting mechanism is provided on the right support frame. The adjusting mechanism includes: a lead screw, which is rotatably connected to the inner wall of the top of the support frame through a bearing. The top end of the lead screw penetrates through the support frame and extends upward. The extended end of the lead screw is fixedly connected to a hand wheel. A slider is threadedly connected to the outer wall of the lead screw. By rotating the hand wheel to drive the lead screw to rotate, the lead screw drives the slider to vertically move under the limitation of the rectangular through hole, so that the slider drives the extension plate to slide along the inner wall of the guardrail plate, thereby being able to adjust the height and area of protection as needed, further improving the practicability.

[0012] Preferably, a rectangular through hole is formed in the left inner wall of the right support frame, and the rectangular through hole penetrates through the guardrail plate. The slider is slidably connected to the inner wall of the rectangular through hole, and the left side of the slider penetrates through the rectangular through hole and is fixedly connected to the extension plate. By providing the rectangular through hole to limit the slider, the rotational movement of the slider is converted into a vertical movement, so that the slider can slide along the inner wall of the rectangular through hole.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. By rotating the fixing bolt to drive the second clamping block to horizontally slide along the outer wall of the sliding rod, the second clamping block and the first clamping block are clamped and fixed on the embedded bolt, thereby fixing the support frame and the guardrail plate. This not only improves the working efficiency during installation, but also is more convenient for subsequent disassembly, improving the practicability;

[0015] 2. By rotating the hand wheel to drive the lead screw to rotate, the lead screw drives the slider to vertically move under the limitation of the rectangular through hole, so that the slider drives the extension plate to slide along the inner wall of the guardrail plate, thereby being able to adjust the height and area of protection as needed, further improving the practicability.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] As Figures 1-4 shown, a bridge safety construction protection structure includes: two support frames 1, a guardrail plate 2 is fixedly connected between the two support frames 1, and fixing mechanisms 3 are arranged on the outer sides of the two support frames 1 away from each other; the fixing mechanism 3 includes: a sleeve 301, the sleeve 301 is fixedly connected to the lower part of the outer wall of the support frame 1, a first clamping block 302 is fixedly connected to the inner wall of the sleeve 301, a fixing bolt 303 is threadedly connected to the outer wall of the sleeve 301, and one end of the fixing bolt 303 extends into the sleeve 301, and the extending end of the fixing bolt 303 is rotatably connected to a second clamping block 304.

[0023] Specifically, a screw sleeve 305 is embedded in the outer wall of the sleeve 301, the fixing bolt 303 is threadedly connected to the inner wall of the screw sleeve 305, the opposite surfaces of the first clamping block 302 and the second clamping block 304 are both arc-shaped, a sliding rod 306 is fixedly connected to the inner wall of the sleeve 301, and the second clamping block 304 is slidably connected to the outer wall of the sliding rod 306. By arranging the sliding rod 306 to limit and guide the second clamping block 304, the second clamping block 304 is prevented from rotating along with the fixing bolt 303, so that the second clamping block 304 slides horizontally along the outer wall of the sliding rod 306. By rotating the fixing bolt 303, the second clamping block 304 is driven to slide horizontally along the outer wall of the sliding rod 306, so that the second clamping block 304 and the first clamping block 302 are clamped and fixed on the embedded bolt, thereby fixing the support frame 1 and the guardrail plate 2, which not only improves the working efficiency during installation, but also is more convenient for subsequent disassembly, improving the practicability.

[0024] As Figures 1-4As shown in the figure, the inside of the guardrail plate 2 is hollow and the top is open. A extension plate 4 is slidably connected to the inner wall of the guardrail plate 2. The inside of both support frames 1 is hollow. An adjusting mechanism 5 is provided on the right support frame 1. The adjusting mechanism 5 includes: a lead screw 501, which is rotatably connected to the top inner wall of the support frame 1 through a bearing.

A slider 503 is threadedly connected to the outer wall of the lead screw 501.

[0025] Specifically, by setting the extension plate 4, the height and area of the protection are increased. A rectangular through hole 504 is opened on the left inner wall of the right support frame 1, and the rectangular through hole 504 penetrates the guardrail plate 2. The slider 503 is slidably connected to the inner wall of the rectangular through hole 504, and the left side of the slider 503 penetrates the rectangular through hole 504 and is fixedly connected with the extension plate 4. The slider 503 is limited by the set rectangular through hole 504, so that the rotational movement of the slider 503 is converted into vertical movement, so that the slider 503 can slide along the inner wall of the rectangular through hole 504. By rotating the hand wheel 502, the lead screw 501 is driven to rotate. The lead screw 501 drives the slider 503 to move vertically under the limitation of the rectangular through hole 504, so that the slider 503 drives the extension plate 4 to slide along the inner wall of the guardrail plate 2, so that the height and area of the protection can be adjusted as needed, further improving the practicability.

[0026] The working principle of the present utility model is as follows: The sleeve 301 is sleeved on the embedded bolt. By rotating the fixing bolt 303, the second clamping block 304 is driven to slide horizontally along the outer wall of the sliding rod 306, so that the second clamping block 304 and the first clamping block 302 are clamped and fixed on the embedded bolt, thereby fixing the support frame 1 and the guardrail plate 2. This not only improves the working efficiency during installation, but also is more convenient for subsequent disassembly. By rotating the hand wheel 502, the lead screw 501 is driven to rotate. The lead screw 501 drives the slider 503 to move vertically under the limitation of the rectangular through hole 504, so that the slider 503 drives the extension plate 4 to slide along the inner wall of the guardrail plate 2, so that the height and area of the protection can be adjusted as needed.
