[0024] According to an embodiment of the present utility model, an edge protection device for road construction is provided.

[0025] Embodiment 1;

[0026] As Figure 1-8 shown, the edge protection device for road construction according to an embodiment of the present utility model includes a plate body structure 1. A buffer structure 2 is connected to one side of the plate body structure 1. An acceleration structure 3 is provided on one side of the buffer structure 2. A pulley group 4 is provided on the plate body structure 1. A counterweight plate 6 is provided at one end of the pulley group 4. A partition plate 7 is provided at the other end of the pulley group 4. Limiting structures 5 are connected to both sides of the counterweight plate 6. A docking structure 8 is connected to the partition plate 7. The plate body structure 1 cooperates with the counterweight plate 6 and the partition plate 7 through the limiting structure 5, so that it can switch between the functions of a closed protection plate and a ventilated protection plate, improving the safety of the protection plate. The pulley group 4 cooperates with a transmission rope for the transmission between the partition plate 7 and the counterweight plate 6. The buffer structure 2 can buffer the transmission process of the counterweight plate 6 to prevent damage to the plate body caused by excessive falling impact force. The docking structure 8 is used to dock the transmission rope with the plate body. The pulley group 4 includes two pulleys. One pulley is installed at the top of the first plate body 101, and the other pulley is installed on one side of the first plate body 101.

[0027] The plate structure 1 includes a first plate 101, ventilation holes 102, a second plate 103, and a limiting plate 104. A limiting plate 104 is fixedly connected to one side of the first plate 101, and the second plate 103 is fixedly connected to the first plate 101 through the limiting plate 104. Ventilation holes 102 are provided on both the first plate 101 and the second plate 103. A sliding cavity is formed between the first plate 101 and the second plate 103, and a partition plate 7 is slidably connected in the sliding cavity. A sliding cavity is formed between the first plate 101, the second plate 103, and the limiting plate 104, and the partition plate 7 is slidably installed in the sliding cavity. The ventilation holes 102 of the first plate 101 and the second plate 103 are respectively located at the upper and lower sections of their plates, and the middle of the plate is fully sealed. The distribution height of the ventilation holes 102 is equivalent to the height of the partition plate 7 and the counterweight plate 6, and the density of the counterweight plate 6 is greater than that of the partition plate 7.

[0028] The buffer structure 2 includes a buffer triangular pad 201 and a support rod 202. The bottom end of the buffer triangular pad 201 is fixedly connected to the support rod 202, and the support rod 202 is fixedly connected to one side of the first plate 101. The buffer triangular pad 201 is fixedly installed on one side of the first plate 101 through the support rod 202, and is used for the final buffer during the falling process of the counterweight plate 6 to prevent the plate from being damaged due to too large a falling impact.

[0029] The acceleration structure 3 includes a compression spring 301, a first connection block 302, a second connection block 303, and a guide rod 304. One end of the compression spring 301 is connected to the first connection block 302, and the first connection block 302 is fixedly installed on one side of the first plate 101. The other end of the compression spring 301 is connected to the second connection block 303. The second connection block 303 is slidably connected to the guide rod 304. Fixed blocks are provided at both ends of the guide rod 304, and the guide rod 304 is fixedly installed on one side of the first plate 101 through the fixed blocks. A transmission rope is connected to the pulley group 4, and one end of the transmission rope is fixedly connected to the second connection block 303, and the other end of the transmission rope is fixedly connected to the hook 802 of the docking structure 8. Since the second connection block 303 is connected to the end of the transmission rope, after the limiting structure 5 releases the limit, the compression spring 301 provides elastic force to increase the speed of the counterweight plate 6 pulling the partition plate 7, and at the same time provides initial power to effectively prevent the problem of excessive static friction that cannot be transmitted due to the pulley group 4 not being transmitted for a long time. Therefore, the acceleration structure 3 can effectively prevent the problem of transmission jamming through the compression spring 301.

[0030] The limiting structure 5 includes a connecting plate 501, a connecting hole 502, a stop block 503, an electric push rod 504, and a limiting block 505. One side of the connecting plate 501 is fixedly connected to a counterweight plate 6. The connecting plate 501 is provided with a connecting hole 502. The other side of the connecting plate 501 is provided with a stop block 503. One end of the stop block 503 is provided with a limiting block 505. The limiting block 505 is connected to an electric push rod 504. The electric push rod 504 is fixedly installed on one side of the first plate body 101. Connecting holes 502 are formed at both the upper and lower ends of the connecting plate 501 of the limiting structure 5, and docking structures 8 are fixedly connected in the connecting holes 502 by threads. The transmission rope bypasses the pulley block 4 from the hook 802 on the partition plate 7 and is connected to the hook 802 of the docking structure 8 at the top end of the connecting plate 501. The hook 802 of the docking structure 8 at the bottom end of the connecting plate 501 is connected to the head end of another transmission rope. The transmission rope is then wound around the pulley block 4 to change its transmission direction, and it is connected to the second connecting block 303 of the acceleration structure 3 in the horizontal direction, enabling the second connecting block 303 to slide on the guide rod 304. The electric push rod 504 can drive the limiting block 505 to transmit. In the closed mode of the protection plate, the limiting block 505 blocks the bottom end of the stop block 503, preventing the bottom end of the counterweight plate 6 from falling under force, and at the same time compressing the compression spring 301. When the electric push rod 504 drives its limiting block 505 to transmit, the counterweight plate 6 loses its support force and then falls. At the same time, it drives the relatively light partition plate 7 to rise through the transmission rope, thereby making the ventilation holes 102 of the plate body communicate with each other, switching the protection plate to the ventilation mode, and preventing the plate body from tipping over due to excessive wind force.

[0031] The docking structure 8 includes a threaded block 801 and a hook 802. The threaded block 801 is fixedly connected with the hook 802. The threaded block 801 is respectively threadedly connected in the connecting hole 502 of the limiting structure 5 and one end of the partition plate 7.

[0032] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0033] In summary, by means of the above technical solutions of the present utility model, the plate structure 1 cooperates with the limiting structure 5 through the counterweight plate 6 and the baffle plate 7, so that it can switch between the functions of the closed protective plate and the ventilated protective plate, improving the safety of the protective plate. The pulley group 4 cooperates with the transmission rope for the transmission between the baffle plate 7 and the counterweight plate 6. The buffer structure 2 can buffer the transmission process of the counterweight plate 6 to prevent damage to the plate body caused by excessive falling impact force. The docking structure 8 is used to dock the transmission rope and the plate body. A sliding cavity is formed between the first plate body 101, the second plate body 103 and the limiting plate 104, and the baffle plate 7 is slidably installed in the sliding cavity. The ventilation holes 102 of the first plate body 101 and the second plate body 103 are respectively in the upper and lower sections of their plate bodies, and the middle of the plate body is fully sealed. The distribution height of the ventilation holes 102 is equivalent to the heights of the baffle plate 7 and the counterweight plate 6. The density of the counterweight plate 6 is greater than that of the baffle plate 7. The buffer triangular pad 201 is fixedly installed on one side of the first plate body 101 through the support rod 202 for the final buffer of the falling process of the counterweight plate 6 to prevent damage to the plate body caused by too large a falling impact. Since the second connecting block 303 connects the end of the transmission rope, after the limiting structure 5 releases the limit, the compression spring 301 provides elastic force to increase the speed of the counterweight plate 6 pulling the baffle plate 7, and at the same time provides initial power to effectively prevent the problem of excessive static friction caused by the pulley group 4 not being driven for a long time and being unable to move. Therefore, the acceleration structure 3 can effectively prevent the problem of transmission jamming through the compression spring 301. Connecting holes 502 are opened at both the upper and lower ends of the connecting plate 501 of the limiting structure 5, and the docking structure 8 is fixedly connected by threads in the connecting holes 502. The transmission rope bypasses the pulley group 4 from the hook 802 on the baffle plate 7 and is connected to the hook 802 of the docking structure 8 at the top end of the connecting plate 501. The hook 802 of the docking structure 8 at the bottom end of the connecting plate 501 is connected to the head end of another transmission rope. The transmission rope is then wound around the pulley group 4 to change its transmission direction, and it is connected to the second connecting block 303 of the acceleration structure 3 in the horizontal direction, so that the second connecting block 303 can slide on the guide rod 304. The electric push rod 504 can drive the limiting block 505 to move. In the closed mode of the protective plate, the limiting block 505 blocks the bottom end of the stopper 503, so that the bottom end of the counterweight plate 6 cannot fall under force, and at the same time, the compression spring 301 is in a compressed state. When the electric push rod 504 drives its limiting block 505 to move, the counterweight plate 6 loses its support force and then falls. At the same time, the lighter baffle plate 7 is driven to rise through the transmission rope, so that the ventilation holes 102 of the plate body are communicated, and the protective plate is switched to the ventilation mode to prevent the plate body from tipping over due to excessive wind force.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
