Description

Technical Field

[0001] The utility model belongs to the field of cofferdams, and in particular relates to a combined cofferdam device with high stability. Background Art

[0002] During the installation of the cofferdam in water, it is necessary to first insert and fix the support column to the bottom of the water, and then connect the positioning frame to the top of the support column through the horn leg, and then position the coaming board on the positioning frame in turn. Usually, the coaming board is inserted into the positioning frame and positioned by bolts to complete the installation. However, when the fit between the coaming boards is not enough and gaps are generated, it is inconvenient to move and adjust the installed coaming boards, which is not conducive to flexible adjustment of the position of the coaming board according to actual installation needs. Utility Model Content

[0003] In view of this, the utility model aims to propose a combined cofferdam device with high stability to solve the technical problem that when the fit between the cofferdams is not enough and gaps are generated, it is inconvenient to move and adjust the installed cofferdams, which is not conducive to flexibly adjusting the position of the cofferdams according to actual installation needs.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0005] A combined cofferdam device with high stability comprises a plurality of support legs, the top ends of the plurality of support legs are fixedly sleeved with horn frames, the top ends of the plurality of horn frames are fixedly connected with an annular frame, and further comprises: an annular mounting groove, the annular mounting groove is opened on the outer ring surface of the annular frame; a plurality of movable plates, both ends of the plurality of movable plates are fixedly connected with support pins, the support pins at both ends of the movable plates are slidably arranged in the annular mounting groove; a plurality of enclosures, the plurality of enclosures are respectively slidably inserted into the surface of the movable plates, and fastening bolts are threadedly inserted between the enclosures and the movable plates; an annular cover plate, the annular cover plate covers the top end of the annular frame, blocks and limits the top ends of the support pins at both ends of the movable plate, and limits the support pins in the annular mounting groove. It should be understood that during the installation process, the number of movable plates to be arranged at the annular mounting groove can be selected according to the width of the enclosure. The smaller the width of the enclosure, the more movable plates should be arranged. Before installing the enclosure, a certain number of support pins on the movable plates are first inserted into the annular mounting groove, and then the annular cover plate is covered on the top of the annular frame. By limiting the top of the support pin, the number of movable plates can be flexibly adjusted for installation.

[0006] After installing the movable plate, the enclosure is positioned on the movable plate in sequence by tightening the bolts. When the position of the movable plate needs to be moved, the enclosure can be directly pushed. After adjusting to a reasonable position, the tightening bolts are tightened so that the end of the fastening bolt is pressed against the inner wall of the annular mounting groove, thereby realizing flexible adjustment and installation of the enclosure position.

[0007] It should be further explained that, through the flexible adjustment of the hoardings, the position of the hoardings can be freely adjusted to adjust the situation where the hoardings are not in ideal fit until the hoardings are in fit, which is conducive to the flexible adjustment and installation of the position of the hoardings according to actual installation needs.

[0008] Furthermore, a fixing bolt is provided between the annular cover plate and the annular frame, and the fixing bolt passes through the annular cover plate and is threadedly connected to the annular frame.

[0009] Furthermore, the bottom end of the annular cover plate has a limiting groove. After the annular cover plate is covered with the annular frame, the limiting groove and the annular mounting groove form an annular groove body that limits the support pin. It should be understood that during the process of limiting the support pin, the limiting groove and the annular mounting groove form an annular groove body that limits the support pin, ensuring that both the top and bottom ends of the support pin are limited in position, and providing a sliding limiting channel for the support pin, so that the support pin and the movable plate as a whole can only move along the trajectory of the annular groove body.

[0010] Furthermore, a plug-in slider is fixedly connected to the surface of the movable plate, and a slide groove adapted to the plug-in slider is provided on the inner side wall of the enclosure. It should be understood that the sliding connection between the plug-in slider and the slide groove on the enclosure can limit the longitudinal sliding of the enclosure, providing support for the vertical downward insertion of the enclosure. On the other hand, it is beneficial to maintain the vertical insertion direction of the enclosure during installation to avoid flipping, thereby preventing the enclosures at different positions from having different insertion directions and causing the enclosures to not fit together.

[0011] Furthermore, a threaded hole is provided at the end of the plug-in slider, and the threaded hole passes through the movable plate. The fastening bolt passes through the enclosure plate and is threadedly connected to the threaded hole.

[0012] Furthermore, the fastening bolt passes through the enclosure plate and the threaded hole in sequence, and the end of the fastening bolt contacts the inner wall of the annular mounting groove.

[0013] Furthermore, the enclosure panels are either first or second combination panels, the first combination panels being curved panels and the second combination panels being flat panels. The first combination panels are mounted at the curved corners of the annular frame, while the second combination panels are mounted at the regular sidewalls of the annular frame. It should be understood that since the annular frame has corners and four regular sidewalls, the enclosure panels need to be adjusted to the annular frame configuration. Therefore, the first and second combination panels are provided to better adapt to the annular frame configuration, ensuring a complete fit between the enclosure panels, thereby further ensuring the stability of the enclosure panels.

[0014] Furthermore, the length of the plug-in slider on the movable plate at the corner of the ring frame is longer than the plug-in slider on the movable plate at the regular side wall position of the ring frame. It should be understood that because the movable plate at the corner of the ring frame is farther away from the corner edge of the ring frame than other positions, the plug-in slider needs to be extended to prevent the sliding groove of the second assembly plate from being unable to plug into the plug-in slider.

[0015] Compared with the prior art, the highly stable combined cofferdam device described in the present invention has the following advantages:

[0016] (1) The utility model describes a high-stability combined cofferdam device, which positions the cofferdams on the movable plate in sequence by fastening bolts. When the movable plate needs to be moved, the cofferdam can be directly pushed. After adjusting to a reasonable position, the fastening bolts are tightened so that the ends of the fastening bolts are pressed against the inner wall of the annular mounting groove. Therefore, by flexibly adjusting the cofferdams, the positions of the cofferdams can be freely adjusted to adjust the undesirable fit between the cofferdams until the cofferdams are in fit, which is conducive to flexibly adjusting the positions of the cofferdams according to actual installation needs.

[0017] (2) The utility model describes a combined cofferdam device with high stability, which forms an annular groove body for limiting the support pin through the limiting groove and the annular mounting groove, ensuring that the top and bottom ends of the support pin are limited, and providing the support pin with a sliding limiting channel, so that the support pin and the limiting plate as a whole can only move along the trajectory of the annular groove body.

[0018] (3) The utility model describes a high-stability combined cofferdam device, which is slidably connected to the sliding groove on the cofferdam by plugging in the slider and the cofferdam, and can limit the longitudinal sliding of the cofferdam, providing support for the vertical downward plugging of the cofferdam. On the other hand, it is beneficial to maintain the vertical plugging direction of the cofferdam during the installation process to avoid flipping, and thus prevent the cofferdams from not fitting together due to different plugging directions of cofferdams at different positions, and thus facilitate fitting the cofferdams together to form a complete enclosure. The cofferdams fit and support each other, which is beneficial to enhancing the integrity of the enclosure, and thus improving the stability of the cofferdam. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] like Figures 1 to 6As shown, a high-stability combined cofferdam device includes multiple supporting legs 1, the top ends of the multiple supporting legs 1 are fixedly sleeved with horn frames 2, and the top ends of the multiple horn frames 2 are fixedly connected with an annular frame 3, and also includes: an annular mounting groove 4, the annular mounting groove 4 is opened on the outer ring surface of the annular frame 3; multiple movable plates 5, both ends of the multiple movable plates 5 are fixedly connected with support pins 6, and the support pins 6 at both ends of the movable plate 5 are slidably set in the annular mounting groove 4; multiple enclosures 7, the multiple enclosures 7 are respectively slidably inserted on the surface of the movable plate 5, and fastening bolts 8 are threadedly inserted between the movable plate 5; an annular cover plate 9, the annular cover plate 9 covers the top end of the annular frame 3, blocks and limits the top ends of the support pins 6 at both ends of the movable plate 5, and limits the support pins 6 in the annular mounting groove 4. It should be understood that during the installation process, the number of movable plates 5 set at the annular mounting groove 4 can be selected according to the width of the enclosure 7. The smaller the width of the enclosure 7, the more movable plates 5 should be set. Before installing the enclosure 7, the support pins 6 on a certain number of movable plates 5 are first inserted into the annular mounting groove 4, and then the annular cover plate 9 is covered on the top of the annular frame 3. By limiting the top of the support pin 6, the number of movable plates 5 can be flexibly adjusted for installation;

[0033] After installing the movable plate 5, the enclosure 7 is positioned on the movable plate 5 in turn by tightening the bolts 8. When the position of the movable plate 5 needs to be moved, the enclosure 7 can be directly pushed. After adjusting to a reasonable position, the tightening bolts 8 are tightened so that the end of the tightening bolts 8 is pressed against the inner wall of the annular mounting groove 4, thereby realizing flexible adjustment and installation of the position of the enclosure 7.

[0034] It should be further explained that, by flexibly adjusting the enclosure 7, the position of the enclosure 7 can be freely adjusted to adjust the situation where the enclosure 7 is not in ideal fit until the enclosure 7 is in fit, which is conducive to flexibly adjusting the position of the enclosure 7 according to actual installation needs.

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown in the figure, as a further optimized embodiment, a fixing bolt 10 is provided between the annular cover plate 9 and the annular frame 3. The fixing bolt 10 passes through the annular cover plate 9 and is threadedly connected to the annular frame 3. It should be understood that in order to stably set the annular cover plate 9 on the annular frame 3, the fixing bolt 10 is used to limit the position, ensuring the stable position of the support pin 6. When disassembly is required, the fixing bolt 10 can be unscrewed.

[0036] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown, specifically, the bottom end of the annular cover plate 9 has a limiting groove 11. After the annular cover plate 9 is covered with the annular frame 3, the limiting groove 11 and the annular mounting groove 4 form an annular groove body for limiting the support pin 6. It should be understood that in the process of limiting the support pin 6, the limiting groove 11 and the annular mounting groove 4 form an annular groove body for limiting the support pin 6, ensuring that both the top and bottom ends of the support pin 6 are limited, and providing the support pin 6 with a sliding limiting channel, so that the support pin 6 and the movable plate 5 as a whole can only move along the trajectory of the annular groove body.

[0037] like Figure 2 、 Figure 3 and Figure 4 As shown, as a further optimized embodiment, a plug-in slider 12 is fixedly connected to the surface of the movable plate 5, and a slide groove 13 adapted to the plug-in slider 12 is provided on the inner side wall of the enclosure 7. It should be understood that the sliding connection between the plug-in slider 12 and the slide groove 13 on the enclosure 7 can limit the longitudinal sliding of the enclosure 7, providing support for the vertical downward insertion of the enclosure 7. On the other hand, it is beneficial to maintain the vertical insertion direction of the enclosure 7 during the installation process to avoid flipping, thereby preventing the enclosure 7 at different positions from having different insertion directions, which causes the enclosure 7 to not fit together.

[0038] Specifically, a threaded hole 1201 is formed at the end of the plug-in slider 12. The threaded hole 1201 passes through the movable plate 5, and the fastening bolt 8 passes through the enclosure 7 and is threadedly connected to the threaded hole 1201. It should be understood that the threaded connection between the threaded hole 1201 and the fastening bolt 8 can position the enclosure 7 on the movable plate 5, so that the enclosure 7 and the movable plate 5 form a whole, thereby achieving the installation of the enclosure 7.

[0039] Specifically, the fastening bolts 8 pass through the enclosure 7 and the threaded holes 1201 in sequence, and the ends of the fastening bolts 8 contact the inner wall of the annular mounting groove 4. It should be understood that after the fastening bolts 8 pass through the enclosure 7 and are threadedly connected to the threaded holes 1201, only the enclosure 7 is positioned on the movable plate 5, but the movable plate 5 is not positioned. By tightening the fastening bolts 8, the ends of the fastening bolts 8 are pressed against the annular wall of the annular mounting groove 4, thereby positioning the movable plate 5.

[0040] like Figure 1 、 Figure 4 and Figure 6As shown, as a further optimized embodiment, the enclosure 7 is a first combined plate 701 or a second combined plate 702. The first combined plate 701 is a curved plate, and the second combined plate 702 is a flat plate. The first combined plate 701 is installed at the curved corner of the annular frame 3, and the second combined plate 702 is installed at the regular side wall of the annular frame 3. It should be understood that since the annular frame 3 has corners and four regular side walls, the enclosure 7 needs to be adjusted according to the shape of the annular frame 3. Therefore, the first combined plate 701 and the second combined plate 702 are provided to better adapt to the shape of the annular frame 3 and to completely fit the enclosure 7, which is conducive to further ensuring the stability of the enclosure 7.

[0041] like Figure 3 and Figure 4 As shown, specifically, the length of the plug-in slider 12 on the movable plate 5 at the corner of the annular frame 3 is longer than the plug-in slider 12 on the movable plate 5 at the regular side wall position of the annular frame 3. It should be understood that because the movable plate 5 at the corner of the annular frame 3 is farther away from the corner edge of the annular frame 3 than other positions, the plug-in slider 12 needs to be lengthened to supplement it to avoid the situation where the sliding groove 13 of the second assembly plate 702 and the plug-in slider 12 cannot be plugged in.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
