[0024] 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 efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0026] Refer to Figures 1-5 As shown in, a tunnel construction operation platform with good protection effect includes a construction operation platform 1, and an adjustment component 2 is arranged above the construction operation platform 1. The adjustment component 2 includes two U-shaped brackets 201 fixedly installed on the top of the construction operation platform 1. A plurality of connecting rods 202 are connected between the two U-shaped brackets 201, and a protective cloth 203 is fixedly connected between the plurality of connecting rods 202.

[0027] The two U-shaped brackets 201 are fixedly installed on the top of the construction operation platform 1. When a worker stands on the top of the construction operation platform 1 to construct the tunnel, the connecting rods 202 can be pulled to adjust the positions of the plurality of connecting rods 202 and the protective cloth 203, so that the worker stands below the protective cloth 203, and then the hand can be extended outside the adjustment component 2 for convenient construction operations;

[0028] Since the protective cloth 203 is soft, the plurality of connecting rods 202 can contract, squeezing the protective cloth 203, thereby adjusting the overall protection area of the connecting rods 202 and the protective cloth 203, and facilitating the movement of the positions of the connecting rods 202 and the protective cloth 203 according to the position where the worker stands, which will neither interfere with the worker's work nor expose the worker completely under the potential falling objects at the top of the tunnel.

[0029] Refer to Figures 1-5 , the material of the protective cloth 203 is high-strength synthetic fiber cloth, the U-shaped bracket 201 is provided with a chute 3, the connecting rod 202 is located inside the chute 3, and the outer wall of the connecting rod 202 is slidably connected with the inner wall of the chute 3.

[0030] The protective cloth 203 made of synthetic fiber material has very high strength and wear resistance, which benefits from the fineness of its fiber structure and the strong intermolecular force. This characteristic enables the protective cloth 203 to withstand a large force and maintain its shape. Therefore, even in the face of the impact of an object falling from a high place, it is not easily damaged, and it can better ensure the safety of workers. The chute 3 provides a sliding direction and space for the connecting rod 202, facilitating the movement of the positions of the connecting rod 202 and the protective cloth 203.

[0031] Refer to Figures 1-5 , one end of the connecting rod 202 is fixedly installed with a gear 4. The gear 4 is located outside the U-shaped bracket 201. An arc-shaped rack 5 meshed with the gear 4 is slidably connected to the outer wall of the U-shaped bracket 201.

[0032] Since a gear 4 is installed at one end of each connecting rod 202, when moving the position of the connecting rod 202, first move the arc-shaped rack 5 away from the gear 4. After the position of the connecting rod 202 is adjusted, release the arc-shaped rack 5 so that the arc-shaped rack 5 catches the gear 4. In this way, the position of the connecting rod 202 can be fixed, and the adjusted connecting rod 202 and the protective cloth 203 are fixed and will not easily shift.

[0033] Refer to Figure 3 , an arc-shaped plate 6 is fixedly installed on the outer wall of the arc-shaped rack 5. A plurality of springs 7 are connected between the bottom of the arc-shaped plate 6 and the top of the U-shaped bracket 201.

[0034] When pulling the arc-shaped rack 5 upward, the arc-shaped plate 6 will stretch the spring 7 at the same time. After the position of the connecting rod 202 is adjusted, release the arc-shaped rack 5, and the spring 7 will automatically pull the arc-shaped plate 6 and the arc-shaped rack 5 back to their original positions, so that the arc-shaped rack 5 tightly catches the gear 4.

[0035] Refer to Figures 3-5 , a plurality of insertion rods 8 are fixedly installed on the top of one of the U-shaped brackets 201. The arc-shaped plate 6 is slidably connected to the outer wall of the insertion rod 8. A baffle 9 is fixedly installed on the top of the insertion rod 8. The insertion rod 8 is located inside the spring 7.

[0036] When the arc-shaped plate 6 and the arc-shaped rack 5 move, the arc-shaped plate 6 will slide along the outer wall of the insertion rod 8. The insertion rod 8 enables the arc-shaped plate 6 to move only vertically, preventing the arc-shaped plate 6 and the arc-shaped rack 5 from shifting, and at the same time making the movement of the arc-shaped rack 5 and the arc-shaped plate 6 more stable.

[0037] Refer to Figure 1 and Figure 4 , a pull rope 12 is fixedly installed on the top of the arc-shaped rack 5. One end of the pull rope 12 away from the arc-shaped rack 5 extends between the U-shaped bracket 201 and the construction operation platform 1.

[0038] Pulling the pull rope 12 can pull the arc-shaped rack 5 to move, without the need for workers to stand on tiptoe or use tools to reach the arc-shaped rack 5.

[0039] Refer to Figure 1 , a pull ring 13 is fixedly installed at one end of the pull rope 12 away from the arc-shaped rack 5.

[0040] The pull ring 13 provides a grip for the worker, so that the worker can hold the pull ring 13 and pull the pull rope 12 to drive the arc-shaped rack 5 to move upward.

[0041] Refer to Figure 4 , two L-shaped fixing rods 10 are fixedly installed on the inner top wall of the U-shaped bracket 201, a support rod 11 is fixedly installed between the two L-shaped fixing rods 10, and the outer wall of the pulling rope 12 abuts against the outer wall of the support rod 11.

[0042] The L-shaped fixing rods 10 fix the support rod 11 above the arc-shaped rack 5, so that the connection position of the pulling rope 12 and the support rod 11 will also become higher. This enables the worker to pull the pulling rope 12 downward, and an upward pulling force will be generated at the end of the pulling rope 12 connected to the arc-shaped rack 5, facilitating the upward movement of the arc-shaped rack 5.

[0043] Working principle:

[0044] Two U-shaped brackets 201 are fixedly installed on the top of the construction operation platform 1. When the worker stands on the top of the construction operation platform 1 to construct the tunnel, the connecting rod 202 can be pulled to adjust the positions of the multiple connecting rods 202 and the protective cloth 203, so that the worker stands below the protective cloth 203, and then the hand can be extended outside the adjusting assembly 2 for convenient construction operations;

[0045] Since the protective cloth 203 is soft, the multiple connecting rods 202 can be contracted, squeezing the protective cloth 203, thereby adjusting the overall protective area of the connecting rods 202 and the protective cloth 203, facilitating the movement of the connecting rods 202 and the protective cloth 203 according to the position where the worker stands, which will neither interfere with the worker's work nor expose the worker completely under the potential falling objects at the top of the tunnel.

[0046] Since a gear 4 is installed at one end of each connecting rod 202, when adjusting the position of the connecting rod 202, first move the arc-shaped rack 5 away from the gear 4. After the position of the connecting rod 202 is adjusted, release the arc-shaped rack 5 so that the arc-shaped rack 5 catches the gear 4, thus fixing the position of the connecting rod 202, and making the adjusted connecting rod 202 and the protective cloth 203 fixed and not easily shifted.
