DETAILED DESCRIPTION

[0028] The following description provides many different embodiments, or examples, for implementing different characteristics of the application. Each of the various embodiments described can provide a single means for implementing a different feature of the application. The description is not to be taken as limiting the scope of the application, but rather providing examples of possible embodiments of the application.

[0029] EMBODIMENT

[0030] The adjusting plate 100 provided by the embodiments of the present application is installed below the comb plate 700 when the comb plate 700 is installed, and is used to adjust the installation height of the comb plate 700. Referring to Figures 1 to 6As shown, the adjusting plate 100 comprises a plate body 110, a supporting block 120, and a threaded rod 130, and the plate body 110 and the supporting block 120 are arranged in a first direction. Referring to Figures 3 to 6 As shown, the first direction is the y-axis direction. The plate body 110 and the supporting block 120 are in surface contact, so that the supporting block 120 can support the plate body 110 and stabilize the position of the plate body 110. The surface of the plate body 110 used for contact with the supporting block 120 is a guide surface 111, which plays a guiding role, and the included angle between the first direction and the guide surface 111 is less than 90 degrees. The threaded rod 130 is threadedly connected with the plate body 110, and the end of the threaded rod 130 is used for abutting against the supporting block 120.

[0031] The supporting block 120 is configured to be pushed by the threaded rod 130 to move relative to the plate body 110 along the guide surface 111 under the rotating motion of the threaded rod 130. The threaded rod 130 is threadedly connected with the plate body 110, and rotating the threaded rod 130 can make the threaded rod 130 move relative to the plate body 110 along its axial direction. The end of the threaded rod 130 abuts against the supporting block 120, and can push the supporting block 120 to move along the guide surface 111 as the threaded rod 130 rotates. Since the included angle between the guide surface 111 and the first direction is less than 90 degrees, when the supporting block 120 moves along the guide surface 111, the supporting block 120 has a component of movement in the first direction, thereby increasing the overall overlapping thickness of the supporting block 120 and the plate body 110 in the first direction, and adjusting the overall thickness of the adjusting plate 100.

[0032] During the installation of the comb plate 700, the first direction is the direction of gravity. Since the adjusting plate 100 can adjust its thickness, the thickness of the adjusting plate 100 can be adjusted when the comb plate 700 is installed, so that the comb plate 700 can be at a preset installation height position, the installation error of the comb plate 700 is eliminated, and the installation quality of the comb plate 700 is improved.

[0033] In specific implementation, the adjusting plate 100 is installed on the pre-embedded pre-embedded plate 210. In the prior art, the height position of the adjusting plate 100 is generally adjusted by increasing the number of gaskets between the adjusting plate 100 and the pre-embedded plate 210. However, the thickness of the gasket is fixed, so the flexibility of adjusting the height position of the adjusting plate 100 is poor, and stepless adjustment of the height position of the adjusting plate 100 cannot be achieved.

[0034] In the present application, the thickness change of the adjusting plate 100 is realized by rotating the threaded rod 130, and the rotation angle of the threaded rod 130 can gradually increase or gradually decrease, so that the gradual change of the thickness of the adjusting plate 100 can be realized, the stepless adjustment of the thickness of the adjusting plate 100 can be realized, the adjustment flexibility of the installation height of the comb plate 700 is increased, the accuracy of the installation height of the comb plate 700 in the first direction is improved, the installation error of the comb plate 700 is reduced, and the installation quality of the comb plate 700 is improved.

[0035] In use, the adjusting plate 100 is installed on the embedded plate 210, the support block 120 is clamped between the plate body 110 and the embedded plate 210, and the position of the support block 120 is adjusted by rotating the threaded rod 130. Compared with directly controlling the relative position of the support block 120 and the plate body 110, the adjustment stability and accuracy of the threaded rod 130 are higher.

[0036] In some embodiments, the end of the threaded rod 130 is in direct contact with the support block 120, and there is no connection relationship between the two. In this way, the threaded rod 130 can only be continuously rotated in the same direction to push the position of the support block 120. If the threaded rod 130 is rotated in the opposite direction, the threaded rod 130 will move away from the support block 120 and cannot push the support block 120 to move. Therefore, attention should be paid to avoid too large rotation angle of the threaded rod 130 during rotation. Alternatively, in the case that the rotation angle of the threaded rod 130 is too large, the threaded rod 130 is first rotated back, the support block 120 is manually controlled to move back, and then the threaded rod 130 is rotated again to push the support block 120 to move, so as to push the support block 120 to the appropriate position again.

[0037] In other embodiments, the end of the threaded rod 130 is rotationally connected with the support block 120. Since the support block 120 slides along the guide surface 111, the position where the support block 120 contacts the threaded rod 130 changes. Therefore, a sliding groove is also provided on the support block 120 for the threaded rod 130 to slide, and the threaded rod 130 is rotationally and slidably connected with the support block 120 to adapt to the change of the relative position between the threaded rod 130 and the support block 120. In the case that the threaded rod 130 is rotated back, the threaded rod 130 can also drive the support block 120 to move back. However, it is necessary to ensure the smoothness of the connection between the threaded rod 130 and the support block 120.

[0038] In some preferred embodiments of the present application, guide rails can also be provided between the support block 120 and the plate body 110 to stabilize the relative position between the support block 120 and the plate body 110, limit the sliding direction of the support block 120, limit the support block 120 to slide along the guide surface 111 only under the push of the threaded rod 130, and avoid the accidental disengagement of the support block 120 from the plate body 110.

[0039] After the comb plate 700 is installed, the installation structure at the bottom of the comb plate 700 is poured to stabilize the installation position of the comb plate 700. That is, the adjusting plate 100 is poured so that the threaded rod 130, the support block 120, and the plate body 110 are poured together to improve the overall structural strength.

[0040] In some embodiments of the present application, referring to Figures 2 to 6 As shown, the plate body 110 is provided with an installation cavity 112 having a first opening communicating with the external environment, and the guide surface 111 is part of the cavity wall of the installation cavity 112; the support block 120 is installed in the installation cavity 112, the cavity wall of the installation cavity 112 is provided with a threaded hole communicating with the installation cavity 112, the threaded rod 130 is arranged in the threaded hole and extends into the installation cavity 112, and abuts against the support block 120 located in the installation cavity 112; the support block 120 can pass through the first opening under the abutting action of the threaded rod 130.

[0041] By arranging the installation cavity 112 inside the plate body 110, the installation position of the support block 120 can be limited, and the sliding direction of the support block 120 can also be limited to avoid the support block 120 sliding in a direction other than the preset direction. The cavity wall of the installation cavity 112 encloses the outside of the support block 120, which can protect the support block 120 to some extent. The first opening is reserved for the support block 120, and the support block 120 moves along the guide surface 111 and can pass through the first opening to move between the external environment and the installation cavity 112 to adjust the overall thickness of the adjusting plate 100. Passing through the first opening can mean that the support block 120 moves from the installation cavity 112 through the first opening to the outside, or that the support block 120 moves through the first opening to the installation cavity 112.

[0042] In some embodiments, the threaded hole can pass through the guide surface 111, referring to Figure 3 and Figure 4 Since the threaded hole passes through the guide surface 111, it occupies part of the area of the guide surface 111, thereby reducing the movable distance of the support block 120. Since the threaded rod 130 moves the support block 120 by abutting against it, the initial position of the support block 120 should be at the limit position where the overall thickness of the adjusting plate 100 is the thickest, and by rotating the threaded rod 130, the support block 120 is pushed to move through the first opening to the installation cavity 112, referring to Figures 3 to 4 the position change trend of the support block 120 in , to reduce the overall thickness of the adjusting plate 100.

[0043] In other embodiments, the threaded hole can be arranged in the cavity wall of the installation cavity 112 where the guide surface 111 is not arranged, referring toFigures 5 to 8 As shown, the presence of the threaded hole does not affect the overall size of the guide surface 111, and does not affect the moving range of the support block 120. By rotating the threaded rod 130, the support block 120 is pushed to move.

[0044] In some preferred embodiments, the support block 120 can be provided as at least two blocks, and multiple support blocks 120 can provide multi-point support to the plate body 110, so that the installation position of the plate body 110 is more stable. The threaded holes corresponding to the two support blocks 120 are located outside the two support blocks 120, and the threaded rods 130 corresponding to the threaded holes are also located outside, as shown in Figures 5 to 8 , which is more convenient for the operator to operate the threaded rod 130.

[0045] In some embodiments, the part of the guide surface 111 away from the threaded hole is inclined away from the side where the first opening is located. Referring to Figure 7 and Figure 8 , that is, the part of the guide surface 111 away from the threaded hole is farther away from the first opening in the first direction, compared with the part of the guide surface 111 close to the threaded hole. By rotating the threaded rod 130, the support block 120 is pushed to move through the first opening towards the installation cavity 112, thereby reducing the overall thickness of the adjustment plate 100, and referring to Figures 7 to 8 , the trend of the position change of the support block 120. By reducing the overall thickness of the adjustment plate 100, the moving direction of the comb plate 700 is the same as the direction of its gravity, and the operator needs smaller force to rotate the threaded rod 130.

[0046] In other embodiments, the part of the guide surface 111 away from the threaded hole is inclined towards the side where the first opening is located. Referring to Figure 5 and Figure 6 , that is, the part of the guide surface 111 away from the threaded hole is closer to the first opening in the first direction, compared with the part of the guide surface 111 close to the threaded hole. By rotating the threaded rod 130, the support block 120 is pushed to move through the first opening towards the outside of the installation cavity 112, thereby increasing the overall thickness of the adjustment plate 100, and referring to Figures 5 to 6 , the trend of the position change of the support block 120, which makes the adjustment of the height of the adjustment plate 100 more convenient.

[0047] Further preferably, when the support block 120 is in contact with the cavity wall provided with the threaded hole, the surface of the support block 120 away from the guide is flush with the first opening. That is, when the overall thickness of the adjustment plate 100 is the thinnest, the support block 120 can be completely accommodated in the installation cavity 112, which is convenient for the installation, transportation and storage of the adjustment plate 100. When the adjustment plate 100 is installed on the preformed plate 210, the operator can easily judge whether the adjustment plate 100 is installed in place.

[0048] The embodiment of the present application also provides an adjusting mechanism, referring to Figures 9 to 14 The adjusting plate 100 provided by any of the above embodiments is movably arranged on the surface of the pre-buried assembly 200, the first fixing member 300 is connected between the adjusting plate 100 and the pre-buried assembly 200, the supporting block 120 is pressed between the pre-buried assembly 200 and the plate body 110, and the side of the plate body 110 away from the pre-buried assembly 200 is used for mounting the comb plate 700, referring to Figure 11 .

[0049] The pre-buried assembly 200 is pre-buried in the early stage of the project, and the adjusting plate 100 is installed again when the comb plate 700 is installed in the late stage of the project. The first fixing member 300 plays a role of fixing the relative positions of the adjusting plate 100 and the pre-buried assembly 200. In addition, the adjusting plate 100 can be moved on the surface of the pre-buried assembly 200, so as to change the position of the adjusting plate 100, change the position of the comb plate 700 connected with the adjusting plate 100, adjust the comb plate 700 to a preset installation position, correct the engineering error generated in the construction process, and compensate for the manufacturing defects of the expansion device and the error caused by the pre-buried pre-buried assembly 200.

[0050] The pre-buried assembly 200 generally includes a pre-buried plate 210, and the pre-buried plate 210 is located at the uppermost of the pre-buried assembly 200, so as to be connected with the adjusting plate 100. In addition, the pre-buried plate 210 is a plate structure, and after being pre-buried, it also does not affect the overhead travelling crane above. The first fixing member 300 plays a role of fixed connection, and can be selected as a bolt and nut cooperation structure, or other fixed structures such as clamping and inserting.

[0051] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 9 and Figure 11 The adjusting plate 100 has a first adjusting through slot 113 penetrating through the plate body 110 in the first direction. Referring to Figure 13As shown, the embedded component 200 has a first through hole 220. The first fixing member 300 is arranged in the first through hole 220 and the first adjusting slot 113, and the adjusting plate 100 can move along the length direction of the first adjusting slot 113 relative to the first fixing member 300. The first fixing member 300 cannot move along the radial direction of the through hole in the first through hole 220, but the adjusting plate 100 can move along the length direction of the first adjusting slot 113 relative to the first fixing member 300, so as to change the relative position of the adjusting plate 100 and the first fixing member 300. Since the position of the first fixing member 300 relative to the embedded component 200 is relatively stable, changing the relative position of the first fixing member 300 and the first adjusting slot 113 is also adjusting the relative position of the embedded component 200 and the adjusting plate 100, and adjusting the comb plate 700 to the preset installation position.

[0052] The embedded component 200 includes not only the embedded plate 210 but also a sleeve 230 and an anchor 240. As shown in Figures 11 to 14 As shown, the sleeve 230 and the anchor 240 are located below the embedded plate 210, which increases the installation stability of the embedded plate 210. The first through hole 220 is generally arranged directly on the embedded plate 210 and communicates with the sleeve 230. When the adjusting plate 100 is not installed, the first fixing member 300 is generally located inside the sleeve 230, and the first through hole 220 is covered by the cover plate 260. As shown in Figure 14 When the adjusting plate 100 and the comb plate 700 are installed, the cover plate 260 is removed, and the first fixing member 300 passes through the first through hole 220 and cooperates with the adjusting plate 100. When the first fixing member 300 is in the form of a bolt and a nut, the bolt structure is located inside the sleeve 230. In addition, a spring 250 is generally arranged in the sleeve 230, and the first fixing member 300 compresses the spring 250 when it is inside the sleeve 230. After the cover plate 260 is removed, the first fixing member 300 can directly extend out of the first through hole 220 under the driving of the spring 250, as shown in Figure 12

[0053] In some embodiments of the present application, in order to further improve the adjustment flexibility of the installation position of the comb plate 700, the adjusting mechanism further includes a second adjusting plate 400 and a second fixing member 500. The second adjusting plate 400 is movably arranged on the side of the adjusting plate 100 away from the embedded component 200, and the moving direction of the second adjusting plate 400 intersects with the moving direction of the adjusting plate 100. The second fixing member 500 is connected between the adjusting plate 100 and the second adjusting plate 400, and the side of the second adjusting plate 400 away from the adjusting plate 100 is used for installing the comb plate 700, as shown in Figure 9

[0054] ​​The adjustment plate 100 and the second adjustment plate 400 cooperate to adjust the position of the comb plate 700 in four directions, facilitate the adjustment of the comb plate 700 to the preset installation position, and cooperate with the adjustable thickness of the adjustment plate 100 to adjust the installation height of the comb plate 700. The second adjustment plate 400 is generally fixed with the comb plate 700 in advance, and the second adjustment plate 400 and the comb plate 700 are fixed as a whole in advance, or can be fixed later, which is not limited by the application. The second fixing member 500 can also select the cooperation structure of the bolt and the nut, or other fixed connection structures.

[0055] In some embodiments, referring to Figure 10 The second adjustment plate 400 has a second adjustment through slot 410, which penetrates through both sides of the second adjustment plate 400 along the first direction. The second fixing member 500 can adjust the position in the second adjustment through slot 410 to change the relative position of the second adjustment plate 400 and the adjustment plate 100. The plate body 110 of the adjustment plate 100 has a second through hole 114, and referring to Figure 2 The second fixing member 500 penetrates through the second through hole 114 and the second adjustment through slot 410. The second adjustment plate 400 can move relative to the second fixing member 500 along the length direction of the second adjustment through slot 410. The second fixing member 500 is relatively fixed with the position of the plate body 110, so that changing the relative position of the second fixing member 500 and the second adjustment through slot 410 can adjust the relative position of the adjustment plate 100 and the second adjustment plate 400.

[0056] In the case that the second fixing member 500 selects the cooperation structure of the bolt and the nut, the bolt penetrates through the second through hole 114 and the second adjustment through slot 410, and when the position adjustment of the second adjustment plate 400 is completed, the nut is sleeved outside the bolt, and the nut is tightened and abuts against the second adjustment plate 400, so that the position of the second adjustment plate 400 and the adjustment plate 100 is fixed.

[0057] In some embodiments, the pre-embedded assembly 200 further comprises a tensile fixing member 600, referring to Figure 9 、 Figure 11 and Figure 12 The tensile fixing member 600 is connected with the pre-embedded plate 210, and when the adjustment plate 100, the second adjustment plate 400, and the comb plate 700 and other structures are installed later, the tensile fixing member 600 is arranged above the pre-embedded plate 210, and when the position adjustment of the comb plate 700 is completed, the concrete is continuously poured towards the upper side of the pre-embedded plate 210, so that the overall position of the expansion device is fixed, and the tensile fixing member 600 enhances the connection between the pre-embedded assembly 200 and the concrete, improves the durability of the concrete, and also reduces the local stress of the concrete. The pre-embedded plate 210 is generally provided with a through hole for the tensile fixing member 600 to pass through, thereby providing installation conditions for the tensile fixing member 600.

[0058] When the pre-embedded plate 210 and the comb plate 700 are installed, the intermediate is supported by the adjusting plate 100 and the second adjusting plate 400, in order to improve the stability of the installation of the comb plate 700, a group of adjusting mechanisms are provided with a plurality of adjusting plates 100 and second adjusting plates 400, the plurality of adjusting plates 100 and second adjusting plates 400 are evenly arranged on the surface of the pre-embedded plate 210, and the comb plate 700 is supported, and the structural stability of the telescopic device is provided.

[0059] The embodiment provides an environmentally-friendly assembly type telescopic device.
