[0026] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0031] like Figure 1 As shown, the utility model proposes a tunnel boring machine safety warning protection device, including multiple groups of protective plates 1, and a warning light 2 is installed on one side of the protective plate 1. The warning light 2 flashes after power is turned on to serve as a warning. A protective net 11 is arranged in the protective plate 1, and the protective net 11 can reduce the overall weight of the protective plate 1 while ensuring a good protective effect. The bottom of the protective plate 1 is fixedly connected with multiple groups of bottom plates 12, and the bottom of each group of bottom plates 12 is equipped with multiple groups of moving wheels 13, so that the protective plate 1 can be moved for easy transportation, thereby improving its portability.

[0032] For further information, see Figure 1-3 and Figure 5 The above-mentioned protective device includes a connecting component 3 for connecting the warning lights 2 in two adjacent groups of protective plates 1. The connecting component 3 includes a slide groove 31, a slider 32, a mounting groove 33, a first conductive sheet 34, and a second conductive sheet 35. Two groups of slide grooves 31 are provided on one side of the protective plate 1. Two groups of sliders 32 corresponding to the positions of the slide grooves 31 are fixedly connected to the side of the protective plate 1 away from the slide grooves 31. The sliders 32 in the two adjacent groups of protective plates 1 are slidably connected to the slide grooves 31, which is convenient for the splicing and installation of the two adjacent groups of protective plates 1. The top of the slider 32 is provided with a mounting groove 33, and the first conductive sheet 34 is installed in the mounting groove 33. The second conductive sheet 35 is also provided in the slide groove 31. After the first conductive sheet 34 contacts the second conductive sheet 35, the warning light 2 set on the side of the protective plate 1 where the slider 32 is installed is connected to the circuit, which is convenient for the power-on of multiple groups of warning lights 2 and reduces the power-on operation.

[0033] Specifically, the above-mentioned protective device also includes a power connection mechanism 4 for driving the second conductive sheet 35 to electrically contact the first conductive sheet 34 when two adjacent groups of protective plates 1 are connected. The power connection mechanism 4 includes a moving block 41, a limiting rod 42, a limiting plate 43, and a first spring 44. The moving block 41 is slidably connected to the slide groove 31. The top of the moving block 41 is inclined, which is used for the slider 32 to squeeze the moving block 41 to slide downward when the slider 32 enters the slider 32. The bottom of the moving block 41 is fixedly connected to a limiting rod 42 that is slidably connected to the protective plate 1, and the limiting rod 42 moves synchronously with the moving block 41. The bottom end of the limiting rod 42 is fixedly connected to a limiting plate 43 that is slidably connected to the protective plate 1. The limiting plate 43 is used for limiting to prevent the moving block 41 from being too high. The first spring 44 sleeved on the outer ring of the limiting rod 42 is set between the moving block 41 and the bottom of the slide groove 31. The limiting rod 42 is used to release the elastic force to drive the moving block 41 to move upward. The power connection mechanism 4 also includes a connecting rod 45, a moving plate 46, a mounting rod 47, a limiting plate 48, and a second spring 49. The connecting rod 45 is fixedly connected to the side of the moving block 41 close to the warning light 2, and the connecting rod 45 moves synchronously with the moving block 41. The top of the connecting rod 45 is fixedly connected to the moving plate 46, and the moving plate 46 moves synchronously with the connecting rod 45. Two groups of mounting rods 47 are slidably connected in the moving plate 46, and the bottoms of the two groups of mounting rods 47 are fixedly connected to the second conductive sheet 35. When the moving plate 46 moves downward, it drives the second conductive sheet 35 to move downward synchronously and approach the first conductive sheet 34. The limiting plate 48 arranged above the moving plate 46 is fixedly connected to the top of the two groups of mounting rods 47 to prevent the second conductive sheet 35 from falling. The second spring 49 sleeved and installed on the outer ring of the mounting rod 47 is arranged between the second conductive sheet 35 and the moving plate 46, and is used to release the elastic force so that the second conductive sheet 35 and the first conductive sheet 34 are closely matched.

[0034] Furthermore, if Figure 4As shown, the protective device also includes a positioning assembly 5 for fixing two adjacent groups of protective plates 1 after they are connected. The positioning assembly 5 includes a mounting hole 51, a mounting block 52, a positioning rod 53, a baffle 54, a clamping plate 55, and a top plate 56. A mounting hole 51 is provided on one side of the protective plate 1. A mounting block 52 corresponding to the mounting hole 51 is installed on the side of the protective plate 1 away from the mounting hole 51. The mounting block 52 is slidably connected to the mounting hole 51. When two adjacent groups of protective plates 1 are connected, the mounting block 52 enters the mounting hole 51. The positioning rod 53 passes through the mounting hole 51 and is slidably connected to the mounting block 52. The positioning rod 53 is used to prevent the mounting block 52 from sliding out, and plays a limiting role to prevent the two groups of protective plates 1 from separating, so that the two groups of protective plates 1 are connected as one. A baffle 54 is fixedly connected to one end of the positioning rod 53, and the baffle 54 is used to limit the position of one end of the positioning rod 53. The end of the positioning rod 53 away from the baffle 54 is slidably connected with a clamping plate 55, which prevents the positioning rod 53 from sliding out of the protective plate 1 after being inserted into the positioning rod 53, thereby ensuring the limiting effect of the positioning rod 53. The top of the clamping plate 55 is fixedly connected with a top plate 56 to prevent the clamping plate 55 from falling downward.

[0035] In this embodiment, first, the two groups of protective plates 1 are brought close to each other, so that the slider 32 and the mounting block 52 on the side of one group of protective plates 1 correspond to the slide groove 31 and the mounting hole 51 on the side of the other group of protective plates 1, so that the sides of the two groups of protective plates 1 fit together. At this time, the slider 32 slides into the slide groove 31, and at the same time squeezes the moving block 41 to move downward. When the moving block 41 moves downward, it compresses the first spring 44. At the same time, when the moving block 41 moves, it drives the moving plate 46 to move downward synchronously through the connecting rod 45. At this time, the second conductive sheet 35 moves downward. After the slider 32 enters the slide groove 31, the first conductive sheet 34 is located below the second conductive sheet 35. When they contact, the first conductive sheet 34 continues to move with the slider 32 and slides into contact with the second conductive sheet 35. At this time, the moving plate 46 continues to move downward and compresses the second spring 49. The elastic force of the second spring 49 causes the second conductive sheet 35 to press tightly against the upper surface of the first conductive sheet 34. At the same time, the mounting block 52 enters the mounting hole 51, the positioning rod 53 passes through the mounting block 52, and the side of the baffle 54 close to the positioning rod 53 contacts the protective plate 1, and then the clamping plate 55 is inserted into the positioning rod 53 to fix the position of the positioning rod 53. At this time, the mounting block 52 is difficult to move out of the mounting hole 51 due to the limiting effect of the positioning rod 53, so that the two adjacent groups of protective plates 1 are reliably connected. The two groups of first conductive sheets 34 installed on the side of the most edge group of protective plates 1 are connected to the power supply, so that multiple groups of warning lights 2 can be powered at the same time, and multiple groups of warning lights 2 are connected in parallel.

[0036] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
