[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 - 5 , the present utility model provides a shield tunnel segment reinforcement device, including a segment body 1; a support frame 11 is provided on the inner side wall of the segment body 1; an electric push rod 12 is fixedly connected to the side wall of the support frame 11; a support plate 13 is fixedly connected to the end of the electric push rod 12; a plurality of ejector rods 14 are hinged to the side wall of the support plate 13; the ejector rods 14 are evenly distributed on the side wall of the support plate 13 and have the same structure; a pulley 15 is fixedly connected to the end of the ejector rod 14; a pair of brackets 16 are fixedly connected to the side wall of the electric push rod 12; the brackets 16 are symmetrically arranged on both sides of the electric push rod 12 and have the same structure; a plurality of cleaning brushes 17 are evenly fixedly connected to the side wall of the bracket 16; during use, the staff transports the support frame 11 into the segment body 1 and places it at a specified position, then starts the electric push rod 12, and the electric push rod 12 pushes the support plate 13 to move, so that the support plate 13 abuts against the side wall of the segment body 1. At the same time, during the process of the support plate 13 approaching the side wall of the segment body 1, the pulley 15 will roll on the side wall of the segment body 1, causing the ejector rods 14 to expand outwards on both sides, and under the action of the torsion spring inside the hinge of the ejector rod 14, a certain reaction force can be applied to press the segment body 1. After that, the segment body 1 can be supported by the support plate 13. And when the electric push rod 12 is operating, the output end surface of the electric push rod 12 can be cleaned by the cleaning brush 17, and the dust and impurities attached to the output end surface of the electric push rod 12 are swept away. During this process, by supporting the segment body 1 with the support plate 13, the reinforcement effect of the segment body 1 after installation can be improved, the firmness of the segment body 1 can be increased, and the cleaning effect on the dust and impurities attached to the output end surface of the electric push rod 12 can be improved by the cleaning brush 17, so as to reduce the influence of dust and impurities entering the electric push rod 12 on its own use effect.

[0027] Furthermore, as Figure 2 、 Figure 4As shown in the figure, a pair of fixing plates 2 are fixedly connected to the side wall of the support frame 11; the fixing plates 2 are symmetrically arranged on both sides of the support frame 11 and have the same structure; a pressing plate 21 is slidably connected to the side wall of the fixing plate 2; the pressing plate 21 penetrates through the wall of the fixing plate 2 and is slidably connected thereto; a bottom plate 22 is fixedly connected to the side wall of the pressing plate 21; a plurality of barbs 23 are evenly fixedly connected to the bottom of the bottom plate 22; an installation frame 24 is fixedly connected to the side wall of the fixing plate 2; a spring 25 is fixedly connected to the side wall of the installation frame 24; a plug 26 is fixedly connected to the end of the spring 25; a pulling plate 27 is fixedly connected to the side wall of the plug 26; the pulling plate 27 penetrates through the wall of the installation frame 24 and is slidably connected thereto; a slot 28 is formed in the side wall of the pressing plate 21; a plurality of universal wheels are evenly fixedly connected to the side wall of the support frame 11; a groove is formed in the side wall of the fixing plate 2; the groove is in sliding fit with the plug 26; during use, through the provided universal wheels, the support frame 11 can be conveniently moved at any time. When the support frame 11 is moved to a designated position, the staff steps on and presses the pressing plate 21, so that the barbs 23 approach the surface of the object. When the pressing plate 21 slides to the designated position, the positions of the slot 28 and the plug 26 can be made to correspond. At this time, the elastic force of the spring 25 can push the plug 26 into the side wall of the slot 28 to catch it, fixing the pressing plate 21 and preventing it from sliding, so that the barbs 23 can firmly grasp the surface of the object to fix the support frame 11. When the support frame 11 needs to be moved, the pulling plate 27 is hooked with a finger and pulled, so that the plug 26 is removed from the side wall of the slot 28, and thus the barbs 23 can be separated from the object. During this process, through the provided universal wheels, the flexibility of the support frame 11 during use can be improved, the convenience of moving the support frame 11 can be increased, and by firmly grasping the surface of the object with the barbs 23, the stability of the support frame 11 after the movement is completed can be improved, playing a role in fixing the support frame 11.

[0028] Further, as Figure 4 、 Figure 5 shown, a pair of spring rods 3 are provided on the side wall of the bottom plate 22; the spring rods 3 are symmetrically arranged on both sides of the bottom plate 22 and have the same structure; a suction cup 31 is fixedly connected to the end of the spring rod 3; during use, when the pressing plate 21 is pressed to lower the bottom plate 22, the suction cup 31 can first come into contact with the surface of the object. Then, through continuous pressing on the pressing plate 21, the suction cup 31 can be fully attached to the surface of the object and generate a certain adsorption force. At the same time, the spring rod 3 can apply a certain reaction force to the suction cup 31, making the suction cup 31 fit more closely with the object to increase the adsorption force and fix the support frame 11. During this process, through the adsorption effect generated by the fit of the suction cup 31 with the surface of the object, the fixing effect between the bottom plate 22 and the object can be improved, the fixing effect on the support frame 11 can be increased, and the phenomenon that the support frame 11 slides due to external factors during use can be reduced.

[0029] Further, such as Figure 3 As shown, the side wall of the bracket 16 is fixedly connected to a connecting rope 4; the end of the connecting rope 4 is fixedly connected to a counterweight ball 41; the side wall of the bracket 16 is fixedly connected to an elastic sheet 42; when in use, the counterweight ball 41 can be made to shake as the support frame 11 moves, and at the same time, the gravity force of the counterweight ball 41 can increase the swing amplitude of the connecting rope 4, and as the counterweight ball 41 swings, the counterweight ball 41 will hit the elastic sheet 42, and the vibration generated by the collision can vibrate off the dust and impurities attached to the side wall of the cleaning brush 17. In this process, the vibration can clean the dust and impurities attached to the side wall of the cleaning brush 17, thereby improving the secondary use effect of the cleaning brush 17 and reducing the difficulty in cleaning the dust and impurities attached to the side wall of the cleaning brush 17 after long-term use.

[0030] Further, such as Figure 4 , Figure 5 As shown, a pair of slide rails 5 are fixedly connected to the side walls of the bottom plate 22; the slide rails 5 are symmetrically arranged on both sides of the bottom plate 22 and have the same structure; a slider 51 is slidably connected to the inner wall of the slide rail 5; the slider 51 is fixedly connected to the spring rod 3; a rubber pad 52 is fixedly connected to the side wall of the slider 51; when in use, the staff holds the spring rod 3 and inserts the slider 51 into the slide rail 5. At this time, a certain friction force will be generated due to the full contact between the rubber pad 52 and the slide rail 5 to fix the spring rod 3. In this process, by fixing the slider 51 by inserting it into the slide rail 5, the suction cup 31 can be conveniently disassembled and replaced, and the suction cup 31 can be reduced from being damaged and difficult to disassemble after long-term use, thereby improving the practicality of the suction cup 31.

[0031] Further, such as Figure 4 As shown, a pair of arc plates 6 are symmetrically fixed to the side walls of the pull plate 27; when in use, since the arc plates 6 have a certain elasticity, the arc plates 6 can be stretched open by placing fingers between the arc plates 6 and the pull plate 27. At the same time, the elastic force of the arc plates 6 can exert a certain reaction force on the fingers, pressing the fingers against the side walls of the pull plate 27. In this process, the fingers are pressed by the arc plates 6, which can increase the firmness of the fingers on the side walls of the pull plate 27, reduce the phenomenon that the fingers are easy to slip off the side walls of the pull plate 27 when pulling, and improve the fixing effect of the fingers on the side walls of the pull plate 27.

[0032] Further, such as Figure 3As shown, a connecting rod 7 is fixedly connected to the side wall of the cleaning brush 17; the connecting rod 7 penetrates through the wall of the cleaning brush 17 and is fixedly connected thereto; during use, when the cleaning brush 17 is cleaning, a plurality of cleaning brushes 17 can be fixedly connected through the connecting rod 7, so that they are concentrated together during cleaning. In this process, the connecting rod 7 can increase the concentration of the cleaning brush 17 during cleaning, improve the cleaning effect of the cleaning brush 17, and reduce the situation that the cleaning brush 17 is too scattered during cleaning, resulting in poor cleaning effect, thereby improving the cleaning effect on the output end of the electric push rod 12.

[0033] Working principle: During use, the staff transports the support frame 11 into the segment body 1 and positions it at the designated location. Then, the electric push rod 12 is activated. The electric push rod 12 pushes the support plate 13 to move, causing the support plate 13 to abut against the side wall of the segment body 1. At the same time, as the support plate 13 approaches the side wall of the segment body 1, the pulley 15 will roll on the side wall of the segment body 1, causing the ejector rod 14 to expand to both sides. And under the action of the torsion spring inside the hinge of the ejector rod 14, a certain reaction force can be applied to press the segment body 1. After that, the segment body 1 can be supported by the support plate 13. When the electric push rod 12 is operating, the output end surface of the electric push rod 12 can be cleaned by the cleaning brush 17, sweeping away the dust and impurities adhering to the output end surface of the electric push rod 12. During use, the universal wheels provided facilitate the movement of the support frame 11 at any time. When the support frame 11 is moved to the designated position, the staff steps on the pressing plate 21 to apply pressure, causing the barbs 23 to approach the object surface. When the pressing plate 21 slides to the designated position, the positions of the slot 28 and the plug 26 can be made corresponding. At this time, the plug 26 can be pushed into the side wall of the slot 28 by the elastic force of the spring 25 to make it stuck and fix the pressing plate 21 so that it does not slide, enabling the barbs 23 to firmly grip the object surface to fix the support frame 11. When the support frame 11 needs to be moved, the finger hooks the pull plate 27 and pulls it, causing the plug 26 to move out of the side wall of the slot 28, so that the barbs 23 can be separated from the object. During use, when pressure is applied to the pressing plate 21 to lower the bottom plate 22, the suction cup 31 first comes into contact with the object surface. Then, by continuously applying pressure to the pressing plate 21, the suction cup 31 can be fully attached to the object surface and generate a certain adsorption force. At the same time, a certain reaction force can be applied to the suction cup 31 by the spring rod 3 to make the suction cup 31 fit more closely with the object, increasing the adsorption force to fix the support frame 11. During use, during the movement of the support frame 11, the counterweight ball 41 can swing as the support frame 11 moves. At the same time, the gravitational force of the counterweight ball 41 can increase the swing amplitude of the connecting rope 4. As the counterweight ball 41 swings, the counterweight ball 41 will impact the elastic piece 42, and the vibration generated by the impact can shake off the dust and impurities adhering to the side wall of the cleaning brush 17. During use, the staff holds the spring rod 3 and inserts the slider 51 into the slide rail 5. At this time, a certain frictional force will be generated by the full contact between the rubber pad 52 and the slide rail 5 to fix the spring rod 3. During use, since the arc-shaped plate 6 has a certain elasticity, by putting the finger between the arc-shaped plate 6 and the pull plate 27, the arc-shaped plate 6 can be expanded. At the same time, due to the elastic force of the arc-shaped plate 6, a certain reaction force can be applied to the finger to press the finger against the side wall of the pull plate 27. During use, when the cleaning brush 17 is cleaning, the connecting rod 7 can fixedly connect multiple cleaning brushes 17 so that they are concentrated together during cleaning.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model.
