Description

The present invention relates to the technical field of steel aqueducts of bridges and particularly relates to a contour detection device and a contour adjustment method for a stainless steel composite corrugated plate. BACKGROUND OF THE INVENTION With the development of the metal material science, stainless steel composite steel plates have been massively applied to steel structure work such as railway bridges gradually. The stainless steel composite steel plates not only solve the corrosion and rust prevention problem of steel plates, but also avoid pollution caused by paint coating. To ensure the safety of the engineering structure and lower the engineering cost, on the premise of not wasting the stainless steel composite steel plate raw materials, it is needed to process the stainless steel composite steel plate into a corrugated stainless steel composite steel plate by way of mold pressing to improve the rigidity of the stainless steel composite steel plate, thereby further guaranteeing the structural strength of the bridge. Particularly for a steel aqueduct, the bottom plate and the side wall plates of the aqueduct are stainless steel composite plates. In particular, a water channel wall plate is the green and environmental-friendly stainless steel composite corrugated plate, which can not only prevent a water body of the channel from being polluted by coating, but also release the axial force and the bending moment caused by water load by means of the corrugated plate. As you can imagine, it is of particular significance to apply the stainless steel composite corrugated plate in the steel aqueduct. However, since the formed corrugated plate subjected to mold pressing has elastic fluctuation, the contour of the corrugated plate may be deviated from a preset contour, thus, the end of the corrugated plate cannot be smoothly inserted into a milling notch of the bottom plate of the aqueduct (the stainless steel composite plate). To avoid this situation, it is needed to examine the contour of the formed corrugated plate. Existing examination modes are usually manual measurement, which are low in efficiency.

As shown in FIGs. 1-3, a contour detection device for a stainless steel composite corrugated plate in the embodiment of the present invention includes an abutment 11, a first upper transverse guide rail 12, a first transverse detection rod 13, a shape follow-up moving mechanism 14 and a detection mechanism, wherein the abutment 11 is configured to have a corrugated plate to be detected 15 placed thereon; the first upper transverse guide rail 12 and the first transverse detection rod 13 are arranged above the abutment 11 from bottom to top in sequence; a shape of the first upper transverse guide rail 12 is consistent with a shape of a cross section of a standard corrugated plate; the first transverse detection rod 13 is transversely provided with a plurality of upper detection blocks 131 in sequence, the upper detection blocks 131 are configured to move up and down relative to the first transverse detection rod 13, a bottom of each of the upper detection blocks 131 is provided with a first sphere 132 and the first sphere 132 at the bottom end of the upper detection block 131 has an initial lower limit position relative to the first transverse detection rod 13, and when all the first spheres 132 are at the respective initial lower limit positions, a first wave line formed by the bottom ends of all the first spheres 132 is consistent with the shape of the cross section of the standard corrugated plate; and the shape follow-up moving mechanism 14 includes a shape follow-up moving seat 141, a movable rod 142 and a lockmg structure, wherein the shape follow-up moving seat 141 is configured to move along the first upper transverse guide rail 12, the vertical rod 142 is vertically and slidably connected to the shape follow-up moving seat 141, the locking structure is configured to lock the vertical rod 142 to the shape follow-up moving seat 141, the movable rod 142 includes a first telescopic rod 1421, a shape follow-up rod 1422 and a first contact rod 1424, a top end of the shape follow-up rod 1422 is connected to a bottom end of the first telescopic rod 1421, a bottom end of the shape follow-up rod 1422 is provided with a third sphere 1423, the first contact rod 1424 is connected to the first telescopic rod 1421, a top end of the first contact rod 1424 is provided with a fourth sphere 1425, and a top end of the fourth sphere 1425 and the bottom ends of the plurality of first spheres 132 are coplanarly arranged; and the detection mechanism is configured to detect a distance of each of the first spheres 132 moving upwards relative to the initial lower limit position. In the embodiment, the formed corrugated plate to be detected 15 subjected to mold pressing (it includes the first horizontal portion 151, the mold pressing and bending portion 153 and the second horizontal portion 152 in sequence in the waveform direction thereof, and in the embodiment, the contour of the mold pressing and bending portion 153 is specifically detected) can be placed on the abutment 11, the first horizontal portion 151 is in contact with the abutment 11, and the cross section of the corrugated plate is parallel to the first upper transverse guide rail 12 and the first transverse detection rod 13 above the abutment 11. The first upper transverse guide rail 12 is slidably connected to the shape follow-up moving mechanism 14. When it is needed to detect the corrugated plate to be detected 15, the movable rod 142 can be locked first through the locking structure (in this state, the movable rod 142 cannot move up and down relative to the shape follow-up moving seat 141), then the first telescopic rod 1421 in the shape follow-up moving mechanism 14 retracts, then the shape follow-up moving mechanism 14 is moved above the first horizontal portion 151 along the first upper transverse guide rail 12, and then the movable rod 142 is unlocked, and the first telescopic rod 1421 stretches till the third sphere 1423 at the bottom end of the shape follow-up rod 1422 at the bottom end of the first telescopic rod 1421 just abuts against the first horizontal portion 151. Meanwhile, the fourth sphere 1425 at the top end of the first contact rod 1424 just abuts against the first sphere 132 in the initial lower limit position, and in this case, the first telescopic rod 1421 is kept at this length. The shape (the first wave line) formed by their bottom ends is the shape of the cross section of the standard corrugated plate when all the first spheres 132 are located at the respective initial lower limit positions. In a case where the shape of the first upper transverse guide rail 12 is consistent with the shape of the cross section of the standard corrugated plate, if the contour of the corrugated plate to be detected 15 is the same as the shape of the cross section of the standard corrugated plate, as the shape follow-up moving seat 141 drives the movable rod 142 to move along the first upper transverse guide rail 12 (in the process, the third sphere 1423 at the bottom end of the shape follow-up rod 1422 moves attaching to the waveform direction of the corrugated plate), all the first spheres 132 shall be located at the respective initial lower limit positions all the time; however, if one first sphere 132 (recorded as a set first sphere 132) is jacked up by a certain distance (recorded as the first adjustment value, and the distance numerical value of the fourth sphere 1425 moving upwards from the initial lower limit position can be detected by the detection mechanism) along the fourth sphere 1425 moving along the first upper transverse guide rail 12, it is indicated that the position where the corrugated plate is located right below the set first sphere 132 is the height of the first adjustment value higher than the standard height. When the shape follow-up moving seat 141 moves along the first upper transverse guide rail 12, numerical value information detected by the detection mechanism can be received by an external control system, and so, whether the contour of the corrugated plate to be detected 15 is qualified is determined, and thus, the detection efficiency is improved. The top end of the fourth sphere 1425 and the bottom ends of the plurality of first spheres 132 are coplanarly arranged, so that it is guaranteed that when the shape follow-up moving seat 141 moves along the first transverse detection rod, if the height of the position of the corrugated plate to be detected 15 is higher than the standard height, the fourth sphere 1425 can jack up the corresponding first sphere 132. It shall be noted that pressure forming of the corrugated plate to be detected 15 means mold pressing of a part of a stainless steel composite plate to form the mold pressing and bending portion 153. The part of the stainless steel composite plate which is not bent forms the first horizontal portion 151 and the second horizontal portion 152 of the present invention. Therefore, the contour detection of the corrugated plate to be detected 15 specifically refers to detection of the contour of the mold pressing and bending portion 153. It shall be noted that when the locking structure locks the movable rod 142, the movable rod 142 cannot move up and down relative to the shape followup moving seat 141, but the first telescopic rod 1421 can retract or stretch if necessary. The first telescopic rod 1421 can be a hydraulic rod, which is controlled by a hydraulic system to retract or stretch or to be kept at a certain length. It shall be noted that the upper detection block 131 is capable of moving up and down relative to the first transverse detection rod 13. When the upper detection block 131 is not subjected to an external force (when it is not jacked up by the fourth sphere 1425), under the action of gravity, the upper detection block has an initial lower limit position relative to the first transverse detection rod 13. Specifically, as shown in FIG. 5, an upper limiting block 133 can be arranged at the top of the upper detection block 131, the upper detection block 131 is capable of moving downwards under the action of gravity relative to the first transverse detection rod 13 till the upper limiting block 133 abuts against the first transverse detection rod 13, and in this case, the first sphere 132 at the bottom end of the upper detection block 131 is at the initial lower limit position. The bottom end of the upper detection block 131 is provided with the first sphere 132, and the top end of the first contact rod 1424 is provided with the fourth sphere 1425, which guarantees that when the shape follow-up moving seat 141 drives the movable rod 142 to move along the first upper transverse guide rail 12, the first contact rod 1424 will not be impeded by the upper detection block 131 and at most jacks up the first sphere 132. Meanwhile, the bottom end of the shape follow-up rod 1422 is provided with the third sphere 1423, which guarantees that the shape follow-up rod 1422 is capable of movmg smoothly along the waveform direction of the corrugated plate to be detected 15 without scraping the corrugated plate to be detected. The locking structure can be a clamping structure. The movable rod can be clamped, so that the movable rod and the shape follow-up moving seat 141 are locked relatively. As shown m FIGs. 1-3, optionally, the contour detection device for a stainless steel composite corrugated plate further includes a second transverse detection rod 16, wherein the second transverse detection rod 16 is arranged below the first transverse detection rod 13, the second transverse detection rod 16 is transversely provided with a plurality of lower detection blocks 161 in sequence, each of the lower detection blocks 161 is configured to move up and down relative to the second transverse detection rod 16, a top end of the lower detection block 161 is provided with a second sphere 162, and the second sphere 162 at the top end of the lower detection block 161 has an initial upper limit position relative to the second transverse detection rod 16, and when all the second spheres 162 are at the initial upper limit positions, a second wave line formed by the top ends of all the second spheres 162 is consistent with the shape of the cross section of the standard corrugated plate; and the movable rod 142 further includes a second contact rod 1426, a second telescopic rod 1428 and a connecting rod 1429, wherein a top end of the second telescopic rod 1428 is connected to the first telescopic rod 1421 through the connecting rod 1429, a bottom end of the second telescopic rod 1428 is connected to the second contact rod 1426, a bottom end of the second contact rod 1426 is provided with a fifth sphere 1427, a bottom end of the fifth sphere 1427 and the top ends of the plurality of second spheres 162 are coplanarly arranged, and the detection mechanism is further configured to detect a distance of each of the second spheres 162 moving downwards relative to the initial upper limit position. In the embodiment, when it is needed to detect the corrugated plate to be detected 15, the movable rod 142 can be unlocked first through the locking structure, so that the third sphere 1423 at the bottom end of the shape followup rod 1422 abuts against the corrugated plate to be detected 15 downwards and the fourth sphere 1425 at the top end of the first contact rod 1424 is lower than the first sphere 132 at the bottom of the corresponding upper detection block 131; then the movable rod 142 is locked through the locking structure and the first telescopic rod 1421 retracts, so that the third sphere 1423 and the corrugated plate to be detected 15 are arranged at an interval; then the second telescopic rod 1428 retracts, the fifth sphere 1427 at the bottom end of the second contact rod 1426 is higher than the second sphere 162 at the top of the corresponding lower detection block 161; Then the shape follow-up moving seat 141 moves on the first upper transverse guide rail 12, so that the shape follow-up rod 1422 at the bottom end of the first telescopic rod 1421 is located above the first horizontal portion 151 of the corrugated plate to be detected 15, and then the movable rod 142 is unlocked through the locking structure, so that the first telescopic rod 1421 stretches till the third sphere 1423 at the bottom end of the shape follow-up rod 1422 abuts against the first horizontal portion 151 and the fourth sphere 1425 at the top end of the first contact rod 1424 abuts against the first sphere 132 right above, and in this case, the first telescopic rod 1421 is kept at this length; then the second telescopic rod 1428 stretches till the fifth sphere 1427 at the bottom end of the second contact rod 1426 abuts against the second sphere 162 below, and in this case, the second telescopic rod 1428 is kept at this length. The shape (the first wave line) formed by their bottom ends is the shape of the cross section of the standard corrugated plate when all the first spheres 132 are located at the respective initial lower limit positions. The shape (the second wave line) formed by their bottom ends is the shape of the cross section of the standard corrugated plate when all the second spheres 162 are located at the respective initial lower limit positions. In a case where the shape of the first upper transverse guide rail 12 is consistent with the shape of the cross section of the standard corrugated plate, if the contour of the corrugated plate to be detected 15 is the same as the shape of the cross section of the standard corrugated plate, as the shape follow-up moving seat 141 drives the movable rod 142 to move along the first upper transverse guide rail 12 (m the process, the third sphere 1423 at the bottom end of the shape follow-up rod 1422 moves attaching to the waveform direction of the corrugated plate), all the first spheres 132 shall be located at the respective initial lower limit positions all the time, and all the second spheres 162 shall be located at the respective initial upper limit positions all the time. However, if one first sphere 132 (recorded as a set first sphere 132) is jacked up by a certain distance (recorded as the first adjustment value, and the distance numerical value of the fourth sphere 1425 moving upwards from the initial lower limit position can be detected by the detection mechanism) along the fourth sphere 1425 moving along the first upper transverse guide rail 12, it is indicated that the position where the corrugated plate is located right below the set first sphere 132 is the height of the first adjustment value higher than the standard height; or, if one second sphere 162 (recorded as a set second sphere 162) is pushed by a certain distance (recorded as the second adjustment value, and the distance numerical value of the second sphere 162 moving upwards from the initial upper limit position can be detected by the detection mechanism) along the fifth sphere 1427 moving along the first upper transverse guide rail 12, it is indicated that the position where the corrugated plate is located right below the set second sphere 162 is the height of the second adjustment value lower than the standard height. When the shape follow-up moving seat 141 moves along the first upper transverse guide rail 12, numerical value information detected by the detection mechanism can be received by an external control system, and so, whether the contour of the corrugated plate to be detected 15 is qualified is determined, and thus, the detection efficiency is improved. It can be understood that only when all the first spheres 132 are not jacked up and all the second spheres 162 are not pushed, the contour of the corrugated plate to be detected 15 is finally determined qualified. Like the first telescopic rod 1421, the second telescopic rod 1428 can be a hydraulic rod either, which is controlled by a hydraulic system to stretch or retract or to be kept at a certain length. The lower detection block 161 is capable of moving up and down relative to the second transverse detection rod 16. When the second sphere 162 at the top of the lower detection block 161 is not pushed by the fourth sphere 1425, the second sphere 162 is at the initial upper limit position. Specifically, as shown in FIG. 6, the top of the lower detection block 161 can be provided with a lower limiting block 163; a portion of the lower detection block 161 located below the second transverse detection rod 16 is sleeved with a reset spring 164; one end of the reset spring 164 is connected and fixed to the lower limiting block 163 and the other end thereof is fixed to the bottom side of the second transverse detection rod 16; in a natural state of the reset spring 164, the second sphere 162 at the top of the upper detection block 131 is at the initial upper limit position; if the second sphere 162 is pushed by the fifth sphere 1427, the reset spring 164 will be lengthened; and when the fifth sphere 1427 no longer gives a downward pressure to the second sphere 162, the reset spring 164 will be reset, so that the second sphere 162 is recovered to the initial upper limit position. As shown in FIG. 1 and FIG. 2, specifically, in a waveform direction of the corrugated plate to be detected 15, the corrugated plate to be detected 15 includes the first horizontal portion 151, the mold pressing and bending portion 153 and the second horizontal portion 152, wherein the first horizontal portion 151 is configured to be in contact with the abutment 11, the abutment 11 is provided with a pedestal 111, the pedestal 111 is configured to be in contact with the second horizontal portion 152, and the abutment 11 is further provided with a straight slot 112 corresponding to the mold pressing and bending portion 153. The pedestal 111 supports the second horizontal portion 152. The distance between the front end and the back end of the straight slot 112 is less than the distance between the front end and the back end of the abutment 11, that is to say, the longitudinal end of the straight slot 112 does not extend to the longitudinal end of the abutment 11. As shown in FIGs. 2-4, optionally, the contour detection device for a stainless steel composite corrugated plate further includes a lower longitudinal guide rail 17, a first trolley 18, a first lower transverse guide rail 19 and sliding seat mechanisms 20, wherein the lower longitudinal guide rail 17 is arranged below the straight slot 112; the first trolley 18 is configured to move along the lower longitudinal guide rail 17; the first trolley 18 is provided with the first lower transverse guide rail 19; a shape of the first lower transverse guide rail 19 is consistent with the shape of the cross section of the standard corrugated plate; the first lower transverse guide rail 19 is provided with the plurality of sliding seat mechanisms 20; each of the sliding seat mechanisms 20 includes a sliding seat body 201 and a third telescopic rod 202; the sliding seat body 201 is configured to move along the first lower transverse guide rail 19; a side, facing the corrugated plate to be detected 15, of the sliding seat body 201 is transversely provided with two third telescopic rods 202 at an interval; and an end, facing the corrugated plate to be detected 15, of each of the third telescopic rods 202 is provided with a contact head structure (21). In the embodiment, after pressure forming, the corrugated plate to be detected 15 can move along the lower longitudinal slide rail on the ground through a transporter (not shown in the drawings), so that the corrugated plate to be detected 15 is transported to a preset position of the abutment 11. The transporter can be provided with a jacking oil cylinder. After the transporter transports the corrugated plate to be detected 15 to the preset position of the abutment 11, the jacking oil cylinder retracts to be separated from the abutment 11 to be detected, so the transporter can leave along the lower longitudinal guide rail 17. In the embodiment, the first trolley 18 can also move below the straight slot 112 along the lower longitudinal guide rail 17. After the first trolley 18 moves below the straight slot 112, the sliding seat mechanism 20 on the first lower transverse guide rail 19 can be controlled, so that the third telescopic rod 202 on one sliding seat mechanism 20 on the first lower transverse rail is located below the left side wall of a groove of the mold pressing and bending portion 153 and the third telescopic rod 202 on the other sliding seat mechanism 20 on the first lower transverse rail is located below the right side wall of the groove of the mold pressing and bending portion 153. Then two third telescopic rods 202 away from each other in the four third telescopic rods 202 on the two sliding seat mechanisms 20 are controlled to stretch till the corresponding two contact head structures 21 abut against the two side walls of the groove of the mold pressing and bending portion 153, respectively. Thus, it can be guaranteed that when the movable rod 142 moves along the first upper transverse guide rail 12, the corrugated plate to be detected 15 will not be driven to move transversely. It can be understood that the lower edge of the abutment 11 is supported on the ground by support legs, so that there is space below the abutment 11 to operate the first trolley 18 and the transporter. As shown in FIG. 2, optionally, the contour detection device for a stainless steel composite corrugated plate further includes an upper longitudinal guide rail 22 and a first connecting frame 23, wherein a top end of the first connecting frame 23 is configured to move along the upper longitudinal guide rail 22, and a bottom end of the first connecting frame 23 fixes the first transverse detection rod 13, the second transverse detection rod 16 and the first upper transverse guide rail 12 relatively. In the embodiment, the upper longitudinal guide rail 22 can be fixed on the ground through a guide rail bracket (not shown in the drawings). The first connecting frame 23 can move along the upper longitudinal guide rail 22 to further drive the first transverse detection rod 13, the second transverse detection rod 16 and the first upper transverse guide rail 12 to move longitudinally synchronously. Thus, the corrugated contours at different longitudinal positions of the corrugated plate to be detected 15 can be detected. As shown in FIG. 7, optionally, the contour detection device for a stainless steel composite corrugated plate further includes a second upper transverse guide rail 24 and a second connecting frame 25, wherein a top end of the second connecting frame 25 is configured to move along the upper longitudinal guide rail 22, a bottom end of the second connecting frame 25 is connected to the second upper transverse guide rail 24, and the second upper transverse guide rail 24 is provided with the sliding seat mechanism 20.

Since the contour adjustment method for a stainless steel composite corrugated plate is used based on the contour detection device for a stainless steel composite corrugated plate, the technical effect of the method is the same as that of the previously mentioned device, and thus, the method is not repeatedly described. Optionally, the step of adjusting the first adjustment position downwards by the first adjustment value includes: a first trolley 18 moves on a lower longitudinal guide rail 17 and a sliding seat mechanism 20 moves on a first lower transverse guide rail 19, wherein two contact head structures 21 at a top end of the sliding seat mechanism 20 are respectively located on both transverse sides of the first adjustment position, and then stretching the corresponding third telescopic rod 202 till the two contact head structures 21 abut against a mold pressing and bending portion 153; a first connecting frame 23 moves along an upper longitudinal guide rail 22 to drive a first transverse detection rod 13, a second transverse detection rod 16 and the first upper transverse guide rail 12 to move towards a direction away from a second connecting frame 25 till the first connecting frame 23 moves to an end of the upper longitudinal guide rail 22; the second connecting frame 25 moves along the upper longitudinal guide rail 22, and the sliding seat mechanism 20 moves along a second upper transverse guide rail 24, wherein the contact head structure 21 arranged at a bottom end of a set third telescopic rod on a bottom side of the sliding seat mechanism 20 moves right above the first adjustment position; and the set third telescopic rod arranged at the second upper transverse guide rail 24 stretches upwards to a set length, wherein a height of the second adjustment position lowers upwards by a distance of the first adjustment value.
