Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In actual use, the protective plate and the fixed post are connected together with steel nails. When the staff disassembles them, they need to pull out the steel nails to separate the fixed post from the protective plate, which makes it inconvenient for the staff to use.

[0022] In view of this, the present invention provides a protective device for construction engineering, which solves the problem that in actual use, the protective plate and the fixed column are connected together with steel nails. When workers disassemble the device, they need to pull out the steel nails to separate the fixed column from the protective plate, which makes it inconvenient for workers to use.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figure 1-5It is known that a protective device for construction engineering includes a base 1, a support rod 11 rotatably connected to the top of the base 1 via a pin, a fixed column 12 rotatably connected to the top of the support rod 11 via a pin, and a protective plate 13 installed on the top of the fixed column 12. The protective device for construction engineering also includes a quick-release structure 2, an adjustment device 3, and a limiting device 4. The quick-release structure 2 is installed between the support rod 11 and the fixed column 12; the adjustment device 3 is installed on the outer wall of the fixed column 12; and the limiting device 4 is installed at the bottom of the protective plate 13. The protective device can be quickly disassembled through the quick-release structure 2, the height of the protective plate 13 can be adjusted by the adjustment device 3, and the limiting device 4 can stabilize the protective plate 13 when supported.

[0025] In the specific implementation process, it is worth noting that the shape of the protective plate 13 is not limited. The protective plate 13 supports the interior of the tunnel and protects the workers. Moreover, the protective plates 13 can be connected together with bolts, which can increase the protective area of ​​the protective device. Under the action of the adjusting device 3, the protective plate 13 is pressed against the top of the inner wall of the tunnel. When disassembling the protective device, the quick-release structure 2 is used to quickly remove the protective plate 13 from the top of the tunnel. The limiting device 4 can make the protective plate 13 stable during installation.

[0026] Furthermore, the quick-release structure 2 includes a limiting block 21, a locking block 22, an insert block 23, and a pull rod 24. The limiting block 21 is fixedly connected to the lower outer wall of the fixed column 12; the locking block 22 is inserted into the inner wall of the limiting block 21, and its bottom is fixedly connected to the upper outer wall of the support rod 11 by bolts; the insert block 23 is inserted into the inner walls of the locking block 22 and the limiting block 21; the pull rod 24 is movably connected to the surface of the limiting block 21; wherein, through the cooperation of the limiting block 21 and the locking block 22, the protective plate 13 is disassembled under the action of the pull rod 24, and the insert block 23 fixes the limiting block 21 and the locking block 22 together;

[0027] In the specific implementation process, it is worth noting that the inner walls of the locking block 22 and the limiting block 21 are provided with slots corresponding to the insert block 23. When installing the protective plate 13, the support rod 11 and the fixing column 12 are rotated to an angle perpendicular to the ground, so that the locking block 22 is inserted into the inside of the limiting block 21, and the insert block 23 is inserted into the inside of the locking block 22 and the limiting block 21. The friction between the insert block 23 and the locking block 22 and the limiting block 21 is used to fix them, and the support rod 11 and the fixing column 12 are fixed, so that the protective plate 13 supports the tunnel. Conversely, when disassembling, the pull rope is connected to the pull rod 24, and the workers pull the pull rod 24 from outside the safe range to separate the locking block 22 and the limiting block 21, and tilt the support rod 11 and the fixing column 12 in the pulling direction, so as to disassemble the protective device as a whole. In this way, the protective plate 13 can be quickly removed from the tunnel.

[0028] Furthermore, the adjustment device 3 includes a handle 31, a driving gear 32, a driven gear 33, a threaded rod 34, an extension rod 35, and a fixing block 36. The handle 31 is rotatably connected to the side wall of the fixing column 12 via a bearing; the driving gear 32 is fixedly connected to one end of the handle 31 extending into the interior of the fixing column 12; the driven gear 33 is meshed with the outer wall of the driving gear 32; the threaded rod 34 is rotatably connected to the interior of the fixing column 12 via a bearing, and one end extending into the interior of the fixing column 12 is fixedly connected to the top of the driven gear 33; the extension rod 35 is threadedly connected to the outer wall of the threaded rod 34 and inserted into the inner wall of the fixing column 12; the fixing block 36 is fixedly connected to the top of the extension rod 35 and rotatably connected to the bottom of the protective plate 13 via a pin. Through the cooperation of the driving gear 32 and the driven gear 33, the handle 31 drives the threaded rod 34 to rotate, and the extension rod 35 drives the fixing block 36 to move, thereby adjusting the height of the protective plate 13.

[0029] In the specific implementation process, it is worth noting that both the driving gear 32 and the driven gear 33 are bevel gears, so that the two can mesh together just right, causing the handle 31 to drive the threaded rod 34 to rotate. The outer wall of the threaded rod 34 is threadedly connected to the inner wall of the extension rod 35, and the extension rod 35 is rectangular in shape. So when the threaded rod 34 rotates, the extension rod 35 will not rotate with the threaded rod 34. This can drive the protective plate 13 to rise and fall, and press against the inner wall of the tunnel for support.

[0030] Specifically, when using this protective device for construction projects, the limiting device 4 is used to fix the protective plate 13, and the support rod 11 and the fixing column 12 are rotated into a straight line. At this time, the locking block 22 is inserted into the limiting block 21, and the insert block 23 is inserted into the locking block 22 and the limiting block 21 to fix the support rod 11 and the fixing column 12. After fixing, the handle 31 is used to drive the threaded rod 34 to rotate. The outer wall of the threaded rod 34 is threadedly connected to the inner wall of the extension rod 35, and the extension rod 35 is rectangular in shape. When the threaded rod 34 rotates, the extension rod 35 will not rotate with the threaded rod 34. This allows the protective plate 13 to be raised and lowered, pressing the protective plate 13 against the top of the inner wall of the tunnel for protection. When disassembling the protective plate 13, the insert block 23 is pulled out from inside the limiting block 21 and the locking block 22, and the connecting rope is wrapped around the outer wall of the pull rod 24. The workers move to a safe distance and pull the pull rod 24, causing the support rod 11 to rotate clockwise and the fixed column 12 to rotate counterclockwise, separating the limiting block 21 and the locking block 22, so that the protective plate 13 can be quickly disassembled.

[0031] Example 2: From Figure 1-5It is known that the limiting device 4 includes a fixed shell 41 and a limiting plate 42. The fixed shell 41 is sleeved on the outer wall of the extension rod 35 and abuts against the bottom of the protective plate 13; the limiting plate 42 is sleeved on the outer wall of the fixing block 36 and fixedly connected to the inner wall of the fixed shell 41; wherein, through the cooperation of the fixed shell 41 and the limiting plate 42, the protective plate 13 is stabilized when it is supported.

[0032] In the specific implementation process, it is worth noting that when installing the protective plate 13, the limiting plate 42 inside the fixing shell 41 is fitted onto the outer wall of the fixing block 36, and the fixing shell 41 is fixed with bolts. This makes the fixing shell 41 support the protective plate 13, preventing the protective plate 13 from rotating with the fixing block 36, which would cause inconvenience in installation. Moreover, after the protective plate 13 is pressed against the top of the tunnel, the fixing shell 41 is removed, which makes it convenient to remove the protective plate 13 when disassembling it.

[0033] Furthermore, a sleeve 14 is fitted onto the outer wall of the support rod 11 and is fixedly connected to the outer wall of the support rod 11 by bolts, with the bottom of the sleeve 14 abutting against the top of the base 1.

[0034] In the specific implementation process, it is worth noting that when installing the protective plate 13, the sleeve 14 is moved downward and pressed against the top of the base 1, so that the support rod 11 is perpendicular to the base 1. This makes the installation of the protective plate 13 stable. After the protective plate 13 is installed, the sleeve 14 is lifted and fixed to the outer wall of the support rod 11 with bolts. This allows the support rod 11 to rotate with the base 1 during subsequent disassembly, making it convenient to disassemble the protective plate 13.

[0035] Specifically, based on the above embodiments, when installing the protective plate 13, the protective plate 13 is fixed with the fixing shell 41, and the base 1 and the support rod 11 are fixed with the sleeve 14. This ensures stability when installing the protective plate 13 and supports the tunnel. When disassembling the protective plate 13, the sleeve 14 on the outer wall of the support rod 11 is moved upward and fixed with bolts. At the same time, the insert block 23 in the locking block 22 and the limiting block 21 is pulled out, and the pull rope is pulled from outside the safe range to make the support rod 11 rotate clockwise. At the same time, the fixing column 12 rotates counterclockwise, so that the protective plate 13 can be quickly removed. This makes the disassembly of the protective plate 13 convenient.

[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.
