Description

Technical Field

[0001] The utility model relates to the technical field of shield concrete segments, in particular to shield concrete segment testing equipment. Background Art

[0002] In reality, after the production of shield concrete segments is completed, their performance needs to be tested. After searching, it was found that the prior art, such as the Chinese patent (grant number: CN219492300U), discloses a shield tunnel segment horizontal assembly test device. By setting a rotating mechanism, the purpose of mutual dislocation of two groups of segments can be achieved. By driving the rotating frame to rotate by a motor, the two groups of segments can be dislocated from each other, thereby simulating a gap degree that is more in line with the actual installation, thereby increasing the accuracy of the gap degree measured during the experiment and the gap degree between the actual one.

[0003] However, when detecting the gap, a ruler is needed, and the operation is that the staff holds the ruler to measure the gap. However, when measuring in this way, the staff's hands are prone to shaking, resulting in unstable measurement and prone to errors, so improvements are needed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a shield concrete segment testing device, which solves the problems mentioned in the background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A shield concrete segment testing device comprises a bottom plate, a rotating frame for splicing segments is installed on the bottom plate via a supporting frame, and a plurality of test segments are spliced ​​on the rotating frame.

[0007] Compared with the prior art, the most important difference of the present invention is that a gap measuring structure is installed on the base plate, the gap measuring structure includes a bracket installed on the base plate, the bracket includes two symmetrically arranged semicircular sliding bars, the two free ends of the two semicircular sliding bars are fixed on the base plate, the ruler is installed between the two semicircular sliding bars, and a ruler that can rotate above the rotating frame is installed on the bracket.

[0008] In order to realize the rotation of the ruler, slip rings are fixed at both ends of the ruler, and the slip rings are slidably installed on the semicircular sliding rod.

[0009] In order to measure the horizontal and vertical gaps, the ruler is a transparent plastic ruler, and the upper surface of the ruler is provided with scale lines along the length direction, and the upper surface of the ruler is provided with a plurality of equally spaced marking lines along the width direction.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the ruler can rotate between two semicircular sliding bars to measure the horizontal and vertical gaps between each test pipe segment. Compared with the method of measuring the gap with a handheld ruler, the utility model is more stable and convenient, and the measurement is very accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1 As shown, the utility model provides a shield concrete segment testing equipment, including a base plate 1, a rotating frame 3 for splicing segments is installed on the base plate 1 through a support frame 2, and a plurality of test segments M are spliced ​​on the rotating frame 3. The above structures are all prior arts. A plurality of test segments M can be spliced ​​and installed on the rotating frame 3. The specific working principle can be referred to the Chinese patent (grant number: CN219492300U), which will not be repeated in the utility model.

[0020] like Figure 2-4 , Figure 6As shown, the main difference between the present invention and the prior art is that a gap measuring structure is installed on the bottom plate 1, the gap measuring structure includes a bracket installed on the bottom plate 1, the bracket includes two symmetrically arranged semicircular sliding bars 5, the semicircular sliding bars 5 are located on both sides of the bottom plate 1, and do not affect the installation of the test tube segment M on the rotating frame 3, the two free ends of the two semicircular sliding bars 5 are fixed on the bottom plate 1, the ruler 4 is installed between the two semicircular sliding bars 5, and the bracket is equipped with a ruler 4 that can rotate above the rotating frame 3.

[0021] like Figure 3-4 As shown, in order to realize the rotation of the ruler 4, slip rings 6 are fixed at both ends of the ruler 4, and the slip rings 6 are slidably installed on the semicircular slide bar 5. After the ruler 4 rotates, in order to stabilize the slip ring 6 on the semicircular slide bar 5, the slip ring 6 can be designed as a magnet ring, and the semicircular slide bar 5 can be an iron rod. In this way, through the suction force between the magnet ring and the semicircular slide bar 5, the slip ring 6 can be stabilized on the semicircular slide bar 5 after the ruler 4 slides.

[0022] like Figure 5 As shown, in order to measure the horizontal and vertical gaps, the ruler 4 is a transparent plastic ruler, and scale lines are arranged on the upper surface of the ruler 4 along the length direction. A plurality of equally spaced marking lines 4-1 are arranged on the upper surface of the ruler 4 along the width direction, and the spacing between two adjacent marking lines 4-1 can be one millimeter.

[0023] After the test segment M is installed on the rotating frame 3, the slip ring 6 is pushed to slide along the semicircular slide bar 5, thereby driving the ruler 4 to rotate between the two semicircular slide bars 5, and then moving the ruler 4 to the position where the gap needs to be measured. The scale lines can be used to measure the longitudinal gap size between adjacent test segments M, and the marking line 4-1 can be used to measure the transverse gap size between adjacent test segments M. After the measurement is completed, the ruler 4 is moved to the lower end of the semicircular slide bar 5 without affecting the removal of the test segment M from the rotating frame 3.

[0024] Finally, the most important contribution of the present invention is that the ruler 4 can rotate between the two semicircular slide bars 5 to measure the horizontal and vertical gaps between each test pipe segment M. Compared with the method of measuring the gap by holding the ruler 4, it is more stable and convenient, and the measurement is very accurate.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
