[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 6 As shown, the utility model is a tunnel construction protection device for road construction, comprising an L-shaped support column 1, characterized in that a protection plate 2 is arranged on one side of the L-shaped support column 1, a fixing component 3 is fixedly installed on the top of the L-shaped support column 1, an adjusting groove 4 is opened on the top of the protection plate 2, an adjusting hollow plate 5 is movably connected inside the adjusting groove 4, a fixing groove 6 is opened on the inner wall of the adjusting groove 4, the fixing groove 6 penetrates the adjusting hollow plate 5, a plurality of fixing grooves 6 on the inner wall of the adjusting groove 4 are arranged in a row, a fixing column 7 is movably connected inside the fixing groove 6 on the adjusting hollow plate 5, a pushing component 8 is arranged on one end of the fixing column 7, the top of the pushing component 8 penetrates the adjusting hollow plate 5 and is fixedly connected with a pulling plate 9, and a spring 10 is arranged on the outer surface of the pushing component 8.

[0031] When the height of the adjusting hollow plate 5 is adjusted, the pushing assembly 8 is pulled upward by the pulling plate 9, so that the pushing assembly 8 drives the fixing column 7 to move out of the fixing groove 6 on the adjusting groove 4. At this time, the adjusting hollow plate 5 can move up and down inside the adjusting groove 4. When the adjusting hollow plate 5 moves to the appropriate position, the pulling plate 9 is released. At this time, the spring 10 can push the pushing assembly 8 downward, so that the pushing assembly 8 pushes the fixing column 7 and moves the fixing column 7 to the fixing groove 6 on the adjusting groove 4. When the fixing column 7 cannot move to the fixing groove 6 on the adjusting groove 4, it is only necessary to move the adjusting hollow plate 5 up and down. When the fixing column 7 is aligned with the fixing groove 6 on the adjusting groove 4, the fixing column 7 can automatically move to the fixing groove 6 on the adjusting groove 4 under the push of the pushing assembly 8 and limit the position of the adjusting hollow plate 5.

[0032] Under the push of the spring 10, the pushing component 8 can push the fixing column 7 and move the fixing column 7 to the inside of the fixing groove 6 on the adjusting groove 4. When it is necessary to adjust the height of the adjusting hollow plate 5, it is only necessary to pull the pulling plate 9 upward, so that the pushing component 8 squeezes the spring 10 and moves the fixing column 7 out from the inside of the fixing groove 6. When the adjusting hollow plate 5 is moved to a suitable height, the pulling plate 9 is directly released. At this time, the spring 10 pushes the pushing component 8 to push the fixing column 7 to the inside of the fixing groove 6 and thereby completes the fixation of the adjusting hollow plate 5. In summary, when adjusting the height of the adjusting hollow plate 5, it is only necessary to pull the pulling plate 9. When the adjusting hollow plate 5 is moved to a suitable height, the pulling plate 9 is directly released, which makes the entire adjustment process more convenient.

[0033] In one embodiment, for the above-mentioned L-shaped support column 1, a T-slot 11 is provided on the top of the L-shaped support column 1 and one side of the protective plate 2, and a T-bar 12 is fixedly connected to one side of the L-shaped support column 1 and the other side of the protective plate 2, and the T-bar 12 on the protective plate 2 is movably connected to the T-slot 11 on the L-shaped support column 1, and the T-slot 11 on the protective plate 2 is sleeved on the outer surface of the T-bar 12 on the L-shaped support column 1.

[0034] The T-slot 11 on one side of the first protective plate 2 is put on the outer side of the T-bar 12 on one side of the L-shaped support column 1, and then the T-slot 11 on one side of the second protective plate 2 is put on the outer side of the T-bar 12 on the other side of the first protective plate 2, and multiple protective plates 2 are connected together. When connecting the last protective plate 2 on one side, fix the second L-shaped support column 1 in a suitable position, and then put the T-slot 11 on one side of the last protective plate 2 on the outer side of the T-bar 12 on the other side of the penultimate protective plate 2, and at the same time, the T-bar 12 on the other side of the last protective plate 2 directly slides into the T-slot 11 on the second L-shaped support column 1. At this point, one side of the protective device is connected. The arrangement of the T-slots 11 and T-strips 12 on both sides of the protective plate 2 makes it possible to directly put the T-slot 11 on the next protective plate 2 on the outer side of the T-bar 12 on the previous protective plate 2 when connecting multiple protective plates 2 together, which makes it more convenient to connect multiple protective plates 2.

[0035] In one embodiment, for the above-mentioned T-block 301, the fixing assembly 3 includes a T-block 301, the T-block 301 is movably connected to the T-slot 11 on the L-shaped support column 1, the top of the T-block 301 is fixedly connected to a fixing plate 302, the top of the fixing plate 302 is threadedly connected to a fixing bolt 303, and the fixing bolt 303 is threadedly connected to the L-shaped support column 1.

[0036] When the T-bar 12 on the other side of the last protective plate 2 slides into the T-slot 11 on the second L-shaped support column 1, directly slide the T-block 301 at the bottom of the fixing plate 302 into the T-slot 11 on the second L-shaped support column 1. At this time, the T-block 301 is in contact with the T-bar 12 inside the T-slot 11, and then the fixing plate 302 is fixed to the top of the L-shaped support column 1 by the fixing bolts 303. Since the next protective plate 2 can press the previous protective plate 2 through the T-slot 11 and the T-bar 12, after completing the connection on one side of the protective device, it is only necessary to fix the last protective plate 2 through the fixing assembly 3 to complete the fixing of all the protective plates 2 on the same side, thereby improving the work efficiency when connecting the protective device.

[0037] In one embodiment, for the above-mentioned pushing assembly 8, the pushing assembly 8 includes a pushing rod 801, the pushing rod 801 is movably connected to the adjusting hollow plate 5, the top of the pushing rod 801 is fixedly connected to the pulling plate 9, the bottom end of the pushing rod 801 is fixedly connected to a T-shaped connecting seat 802, both ends of the T-shaped connecting seat 802 are rotatably connected to a rotating rod 803, one end of the rotating rod 803 is rotatably connected to the fixed column 7, and the spring 10 is arranged between the T-shaped connecting seat 802 and the top of the inner wall of the adjusting hollow plate 5.

[0038] By pulling the pull plate 9, the pull plate 9 pulls the push rod 801 upward, and the push rod 801 drives the T-shaped connecting seat 802 to move upward and causes the T-shaped connecting seat 802 to squeeze the spring 10. At this time, the rotating rod 803 moves upward and rotates under the pulling of the T-shaped connecting seat 802, so that one end of the rotating rod 803 can pull the fixing column 7 and make the fixing column 7 move out from the inside of the fixing groove 6. When the pull plate 9 is released, the fixing column 7 can be moved to the inside of the fixing groove 6 again under the push of the rotating rod 803. The fixing column 7 can be moved horizontally by only pulling the pushing assembly 8 upward through the pull plate 9. This setting makes it possible to pull the pull plate 9 while pulling the hollow adjustment plate 5 upward, so that it is more convenient to adjust the height of the hollow adjustment plate 5.

[0039] In one embodiment, for the above-mentioned adjustable hollow plate 5 , a guide plate 13 is fixedly connected to the inner wall of the adjustable hollow plate 5 , and the fixing column 7 is movably connected to the guide plate 13 .

[0040] Two guide plates 13 are arranged upper and lower inside the adjusting hollow plate 5, and the two guide plates 13 are both fitted together with the fixed column 7. When the fixed column 7 moves, the two guide plates 13 can guide it, so that the fixed column 7 can move straight under the pull of the rotating rod 803. At the same time, the setting of the guide plates 13 allows the rotating rod 803 to pull and push the fixed column 7 normally.

[0041] In one embodiment, for the above-mentioned adjustable hollow plate 5 , a handle 14 is fixedly connected to the top of the adjustable hollow plate 5 , and both sides of the pull plate 9 are in contact with the inner wall of the handle 14 .

[0042] When adjusting the height of the adjustable hollow plate 5, the handle 14 can be used to pull the adjustable hollow plate 5 upwards, and at the same time, the operator can pull the pull plate 9 inside the handle 14, so that the fixing column 7 no longer fixes the adjustable hollow plate 5. The entire operation process can be completed by the operator with one hand, which makes it more convenient to adjust the height of the adjustable hollow plate 5.

[0043] In one embodiment, for the L-shaped support column 1 , a bottom plate 15 is fixedly connected to the bottom of the L-shaped support column 1 , and a fixing hole 16 is opened at the top of the bottom plate 15 .

[0044] The L-shaped support column 1 is placed at a suitable position, and then the fixing nails are passed through the fixing holes 16 to fix the bottom plate 15. After the fixing is completed, the stability of the L-shaped support column 1 when supporting the protective plate 2 can be guaranteed under the support of the bottom plate 15.

[0045] Through the above technical solution, 1. The handle 14 is used to pull the adjusting hollow plate 5 upward, and the pull plate 9 is pulled upward while the handle 14 is pulled. At this time, the pull plate 9 pulls the T-shaped connecting seat 802 upward through the push rod 801, and the T-shaped connecting seat 802 drives one end of the rotating rod 803 to move upward and rotate, and the other end of the rotating rod 803 pulls the fixing column 7 and makes the fixing column 7 move out of the fixing groove 6. At this time, the adjusting hollow plate 5 can slide inside the adjusting groove 4. When the adjusting hollow plate 5 is moved to a suitable position, the pulling plate 9 is released. At this time, the spring 10 pushes the T-shaped connecting seat 802 downward and causes one end of the rotating rod 803 to move downward and rotate. The fixing column 7 can move to the inside of the corresponding fixing groove 6 under the push of the rotating rod 803 and complete the fixing of the adjusting hollow plate 5. In summary, when adjusting the height of the adjusting hollow plate 5, it is only necessary to pull and release the pulling plate 9, and the operator can complete the pulling of the adjusting hollow plate 5 and the pulling plate 9 with one hand. This makes it more convenient to adjust the height of the hollow plate 5, thereby improving the effect of assembling and connecting the protective device; 2. When the T-shaped strip 12 on the last protective plate 2 on one side of the protective device slides into the inside of the T-shaped slot 11 on the L-shaped support column 1, directly slide the T-shaped block 301 at the bottom of the fixing plate 302 into the inside of the T-shaped slot 11 on the second L-shaped support column 1. At this time, the T-shaped block 301 contacts the T-shaped strip 12 inside the T-shaped slot 11, and then fix the fixing plate 302 with the fixing bolts 303. 2 is fixed on the top of the L-shaped support column 1, so that the fixing component 3 can fix the T-shaped bar 12 inside the T-shaped slot 11. Since the next protective plate 2 in the connected protective plates 2 can press the previous protective plate 2 through the T-shaped slot 11 and the T-shaped bar 12, after completing the connection on one side of the protective device, it is only necessary to fix the last protective plate 2 through the fixing component 3 to complete the fixing of all protective plates 2 on the same side of the protective device, thereby improving the work efficiency when connecting the protective device.
