Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0025] Please see Figures 1-3 As shown, this embodiment discloses a test bench, specifically a test bench suitable for horizontal assembly and testing of various types of tunnel segments, including: a transport platform 101, a mounting platform 103, and a clamping structure; the transport platform 101 is used to slide on a track 102; a driving device is installed on the mounting platform 103, and the driving device is used to drive the transport platform 101 away from or close to the mounting platform 103; the clamping structure is installed on the transport platform 101 and is used to clamp the tunnel segment 104; the clamping structure includes a clamping plate 105, a support plate 106, a screw 107, and a soft pad 108. The clamping plate 105 is slidably installed on the transport platform 101, the support plate 106 is fixedly installed on the transport platform 101, the soft pad 108 is respectively disposed on the clamping plate 105 and the support plate 106, and the screw 107 is threadedly connected to the transport platform 101 and rotatably connected to the end face of the clamping plate 105;

[0026] This utility model mainly includes a transport platform 101, an installation platform 103, and a clamping structure. In actual use, the operator first needs to determine the radius of the assembled shield tunnel segment 104 by observing its curvature. Then, the transport platform 101 is driven by a drive device to move away from the installation platform 103 until the distance from the axis of the installation platform 103 to the axis of the transport platform 101 is the same as the radius of the shield tunnel segment 104. At this point, the drive device is stopped, and the shield tunnel segment 104 is then installed on the transport platform. On platform 101, screw 107 is rotated. After screw 107 rotates, clamping plate 105 moves on transport platform 101. Soft pad 108 deforms after contacting shield tunnel segment 104 until clamping plate 105 and support plate 106 clamp shield tunnel segment 104. Then screw 107 is stopped, thus completing the assembly of several shield tunnel segments 104. The advantage of this setup is that several transport platforms 101 are automatically aligned by a drive device, making it convenient to use and highly efficient in installing shield tunnel segments 104.

[0027] In some embodiments, the transport platform 101 includes a base 109 and a plurality of rollers 110. The rollers are disposed on the lower end surface of the base 109 and the rollers 110 are used to slide on the track 102. The support plate 106 is fixedly installed on the base 109 and the clamping plate 105 is slidably connected to the base 109.

[0028] In actual use, the purpose of setting the roller 110 is to facilitate the movement of the transport platform 101. The track 102 radially limits the roller 110 to prevent the lead screw nut 121 from rotating synchronously with the ball screw 120.

[0029] In some embodiments, a threaded seat 111 is provided on the base 109, and the screw 107 is threadedly connected to the base 109 through the threaded seat 111.

[0030] In actual use, the purpose of setting the threaded seat 111 is to facilitate the threaded connection between the screw 107 and the base 109.

[0031] In some embodiments, the clamping plate 105 is provided with a rotating groove 112, and the end of the screw 107 is always located inside the rotating groove 112 and rotatably connected to the rotating groove 112.

[0032] In actual use, the purpose of setting the rotating groove 112 is to facilitate the rotation between the screw 107 and the clamping plate 105.

[0033] In some embodiments, the clamping plate 105 has a U-shaped structure, and a sliding groove is provided on the surface of the clamping plate 105 that contacts the side wall of the base 109. A slide rail is provided on the side of the base 109, and the sliding groove and the slide rail are slidably connected.

[0034] In actual use, the purpose of setting the clamping plate 105 into a U-shaped structure is to facilitate the sliding fit between the clamping plate 105 and the base 109.

[0035] In some embodiments, the mounting platform 103 includes an upper plate 113, a lower plate 114, and a plurality of support rods 115. The two ends of the plurality of support rods 115 are respectively connected to the upper plate 113 and the lower plate 114. The number and position of the support rods 115 correspond to the transport platform 101.

[0036] In actual use, the support rod 115 is used to support the upper plate 113 and the lower plate 114, so that an installation area is formed between the upper plate 113 and the lower plate 114.

[0037] In some embodiments, the drive device includes a motor 116, a rotating shaft 117, a driving bevel gear 118, and a plurality of driven bevel gears 119. The motor 116 is fixedly mounted on the upper plate 113. The output shaft of the motor 116 passes through the upper plate 113 and is connected to the rotating shaft 117. The rotating shaft 117 is rotatably connected to the upper plate 113 and the lower plate 114. The driving bevel gear 118 is fixedly mounted on the output shaft of the motor 116. The number and position of the driven bevel gears 119 correspond to the number and position of the support rods 115. The driving bevel gear 118 meshes with the plurality of driven bevel gears 119. A ball screw 120 is rotatably mounted on the support rods 115. One end of the ball screw 120 is fixedly connected to the driven bevel gear 119, and the other end is fitted with a screw nut 121. The screw nut 121 is fixedly connected to the bottom of the base 109.

[0038] In actual use, after the motor 116 rotates, it drives the rotating shaft 117 and the driving bevel gear 118 to rotate. After the driving bevel gear 118 rotates, it drives the four driven bevel gears 119 to rotate, which in turn drives the four ball screws 120 to rotate. After the four ball screws 120 rotate, the rollers 110 at the bottom of the transport platform 101 are radially limited by the track 102. Under the action of the screw nut 121, the ball screws rotate and drive the transport platform 101 away from or close to the mounting platform 103, thereby achieving the purpose of controlling the movement of the transport platform 101 by rotating the motor 116.

[0039] In some embodiments, a mounting base 122 is fixedly provided on the upper plate 113, and the motor 116 is fixedly connected to the mounting base 122 through several connecting rods 123.

[0040] In actual use, the purpose of setting the mounting base 122 is to facilitate the installation of the motor 116.

[0041] In some embodiments, a recess 124 is provided on the base 109, the recess 124 being used to fit against the sidewalls of the upper plate 113 and the lower plate 114.

[0042] In actual use, the purpose of setting the recess 124 is to allow the base 109 to fit completely against the upper plate 113 and the lower plate 114 when the base 109 is close to the upper plate 113 and the lower plate 114.

[0043] In some embodiments, the ball screw 120 is provided with a scale.

[0044] In actual use, the purpose of setting the scale is to facilitate the staff to observe the distance the lead screw nut 121 moves, so as to accurately control the distance the transport platform 101 moves.
