DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, the utility model describes a reinforcement mechanical arm assembly for repairing shield subway tunnel segments, comprising a top support arm portion 1 and an annular sliding portion 2. The top support arm portion 1 is provided in at least one group and is arranged on the circumference of the annular sliding portion 2. An inner frame 3 is provided in the annular sliding portion 2, and lower support seats 4 for support are provided on both sides of the bottom of the annular sliding portion 2. The lower support seats 4 are respectively connected to both sides of the inner frame 3.

[0022] When in use, the top support arm 1 and the annular sliding part 2 provide a reinforcement mechanism capable of adjusting the support angle 360° for the shield subway tunnel segment repair operation, so that the segments to be repaired at any angle in the shield tunnel can be reinforced and supported during the repair operation, thereby improving the flexibility of tunnel segment repair and ensuring the safety of construction workers during the repair period.

[0023] The utility model further includes that the supporting arm portion 1 includes an arc-shaped supporting plate 11 and a first hydraulic push rod 12 , and the arc-shaped supporting plate 11 is installed on the output end of the first hydraulic push rod 12 .

[0024] When in use, the supporting arm 1 is used to push the pipe segment so that the pipe segment can be stably pressed against the tunnel wall.

[0025] The present invention also includes that the annular sliding portion 2 includes an annular guide rail 21, an arc-shaped slider 22 is slidably connected to the annular guide rail 21, and tooth grooves 211 are provided on both sides of the inner side of the annular guide rail 21, and the sleeve of the first hydraulic push rod 12 is fixed on the arc-shaped slider 22.

[0026] The present invention also includes that a servo motor 23 and a reduction motor 24 are installed on one side of the arc-shaped slider 22, the driving end of the servo motor 23 is connected to the input end of the reduction motor 24, and a gear 25 is installed on the output end of the reduction motor 24, and the gear 25 is engaged with the tooth groove 211.

[0027] When in use, the annular sliding portion 2 provides 360° working position adjustment conditions for the supporting arm portion 1 .

[0028] The present invention further comprises that second hydraulic push rods 41 are installed on the tops of both ends of the lower support seat 4 , and the bottoms of the second hydraulic push rods 41 pass through the lower support seat 4 and are equipped with support wheels 42 .

[0029] When in use, the lower support base 4 is used to support the entire assembly in the tunnel.

[0030] When the present invention is in use, the supporting wheel 42 is used as a whole to push the supporting arm 1 to the shield subway tunnel where the operation is required, so that the top support arm 1 reaches the position of the pipe segment required to be supported and reinforced, and the power supply components in the operating tunnel provide power to the electrical components in this application. After reaching the operating position, the output end of the second hydraulic push rod 41 is extended and retracted, so that the support height of the lower support seat 4 in the tunnel is adjusted until it reaches the required operating height. Subsequently, the reduction motor 24 provides driving force to the reduction motor 24, so that the reduction motor 24 drives the gear 25 to rotate. The gear 25 is engaged with the tooth groove 211, so that the arc-shaped slider 22 drives the top support arm 1 to move along the circumference of the annular guide rail 21, during which the top support arm 1 used for the pipe segment required to be supported and reinforced is ensured. The support arm portion 1 also has a group of top support arm portions 1 on the circumference of the symmetrical positions of the annular guide rail 21, so that when the top support arm portion 1 used for the pipe segment that needs to be supported and reinforced applies pressure to the pipe segment, the pressure can be transmitted to the pipe segment in the symmetrical position, thereby ensuring the stable use of the overall reinforcement mechanism. During support and reinforcement, the arc-shaped support plate 11 is pushed out through the output end of the first hydraulic push rod 12, so that the pipe segment that needs to be reinforced and supported is pushed and squeezed by the arc-shaped support plate 11, so that the pipe segment can be firmly fixed to the inner wall of the tunnel, and when the arc-shaped support plate 11 pushes the pipe segment, it avoids the area that needs to be repaired, and then fills the defective area of ​​the pipe segment and performs a series of repair operations. The reinforcement mechanical arm mechanism of the present application can greatly improve the working safety of tunnel pipe segment repair personnel.
