Description

Technical Field

[0001] The present application relates to the technical field of transport devices, and in particular to a detachable transport structure for protecting expansion joints. Background Art

[0002] An expansion joint is a flexible element that can compensate for axial deformation to a limited extent. It has the characteristics of large axial flexibility and easy deformation. It can compensate for the thermal expansion difference between the various parts of the structure due to different temperatures, reduce the axial load between them, and thus reduce the temperature difference stress between the various parts of the structure. There are many types of expansion joints, the most common ones are corrugated, ring plate welding and sandwich shell structures.

[0003] At present, in the process of transporting expansion joints, poor road conditions or long-distance sea transportation may be encountered. The vibration during transportation is large, and the flexible expansion joints are easily damaged during transportation, resulting in an increase in the scrap rate of the expansion joints.

[0004] In view of the above-mentioned related technologies, the inventor believes that it is necessary to design a transportation structure to meet the requirements of protecting the expansion joint's transportation stability and reduce the possibility of damage to the expansion joint during transportation. Utility Model Content

[0005] In order to protect the expansion joint during transportation and reduce the possibility of damage to the expansion joint, the present application provides a detachable transportation structure for protecting the expansion joint.

[0006] The present application provides a detachable transport structure for protecting expansion joints using the following technical solution:

[0007] A detachable transport structure for protecting expansion joints, comprising a bracket arc plate and an inner positioning assembly, wherein the bracket arc plate is in a semi-cylindrical shape, two bracket arc plates are provided, and the two bracket arc plates are connected by a connecting piece, and an inner positioning assembly is provided on the bracket arc plate, and the inner positioning assembly comprises a positioning plate group, and the positioning plate group comprises two groups arranged on the inner arc wall of the bracket arc plate along the vertical direction, and the positioning plate group comprises an upper abutment plate and a lower abutment plate, and the upper abutment plate and the lower abutment plate are both arranged on the inner arc wall of the bracket arc plate, and the upper abutment plate is arranged above the lower abutment plate, and the planes where the upper abutment plate and the lower abutment plate are located are perpendicular to the central axis of the bracket arc plate.

[0008] By adopting the above technical solution, when protecting the expansion joint, two semi-annular bracket arc plates are surrounded on the outside of the expansion joint and the two are formed into a whole cylinder. The two sets of internal positioning components arranged in the bracket arc plate correspond to the two flanges at both ends of the expansion joint, and the flanges are clamped between the corresponding upper abutment plate and the lower abutment plate to achieve the fixation of the flanges. The bracket arc plate protects the bellows section of the expansion joint, reducing the possibility of damage to the expansion joint due to vibration during transportation. Through the mutual cooperation of the bracket arc plate and the internal positioning component, it has the effect of protecting the expansion joint during transportation and reducing the possibility of damage to the expansion joint.

[0009] Optionally, the connecting member is a clamp, and the clamp is commonly connected to the outside of the two bracket arc plates to lock the two bracket arc plates.

[0010] By adopting the above technical solution, the clamp is connected to the outside of the two bracket arc plates in a detachable manner, thereby realizing a detachable connection of the two bracket arc plates.

[0011] Optionally, a limiting plate group is provided on the outer arc wall of the bracket arc plate, and the limiting plate group includes two limiting clamping plates, the limiting clamping plates are connected to the outer arc wall of the bracket arc plate, and the clamp passes through between the two limiting clamping plates.

[0012] By adopting the above technical solution, the two limiting clamping plates limit the clamp, thereby reducing the possibility of the clamp falling off when connecting and fixing the two bracket arc plates.

[0013] Optionally, the top surface of the lower abutment plate is provided with an abutment slope, and the longitudinal cross-sectional area of ​​the lower abutment plate decreases in a direction away from the inner ring wall of the bracket arc plate.

[0014] By adopting the above technical solution, the flange is inserted between the upper abutment plate and the lower abutment plate. Since the top surface of the lower abutment plate is provided with an abutment slope, the abutment slope fits with the bottom surface of the flange, so that the flange can always fit tightly with the upper abutment plate and the lower abutment plate without any gap.

[0015] Optionally, an insertion plate is connected to one of the radial end faces of the bracket arc plate, and a slot corresponding to the shape of the insertion plate is opened on the other radial end face of the bracket arc plate. When the two bracket arc plates are spliced ​​together, the insertion plate on one bracket arc plate is inserted into the slot on the other bracket arc plate.

[0016] By adopting the above technical solution, when two bracket arc plates are spliced ​​together, the plug plate on one bracket arc plate is inserted into the slot on the other bracket arc plate, and the two ends of the two bracket arc plates in the length direction are kept flush. The arrangement of the plug plate and the slot avoids the possibility of relative sliding of the bracket arc plates when connected, further improves the structural stability of the device, and also reduces the structural stress on the limit clamp plate and the clamp.

[0017] Optionally, an abutment rubber pad is connected to the abutment slope.

[0018] By adopting the above technical solution, the provision of the abutting rubber pad reduces the possibility of the bottom surface of the flange being damaged during fixing.

[0019] Optionally, the bracket arc plate includes an upper adjustment arc plate located above and a lower adjustment arc plate located below, the bottom end of the upper adjustment arc plate is connected to a sliding plate, the lower adjustment arc plate is provided with a sliding groove corresponding to the sliding plate, the sliding plate is slidably set in the sliding groove, and the lower adjustment arc plate is provided with a locking member for locking the sliding plate.

[0020] By adopting the above technical solution, the overall length of the expansion joint, which has been connected to the external structure at both ends, is not convenient to adjust. The position of the sliding plate in the sliding groove is adjusted so that the two sets of internal positioning components correspond to the flange positions at both ends of the expansion joint. After the position adjustment of the sliding plate is completed, the position of the sliding plate in the sliding groove is locked using a locking member. The setting of the sliding plate and the sliding groove expands the scope of application of the device.

[0021] Optionally, the lower abutment plate is slidably matched with the bracket arc plate, and an adjusting screw is rotatably connected to the inner wall of the bracket arc plate, and the length direction of the adjusting screw is parallel to the central axis direction of the bracket arc plate. The adjusting screw is threadedly connected to the lower abutment plate, and a sliding block is connected to the side of the lower abutment plate close to the bracket arc plate. An adjustment groove is opened on the inner arc wall of the bracket arc plate, and the length direction of the adjusting groove is parallel to the adjusting screw, and the sliding block is slidably set in the adjustment groove.

[0022] By adopting the above technical solution, for flanges of different thicknesses, the spacing between the upper abutment plate and the lower abutment plate needs to be adjusted. By rotating the adjusting screw, the lower abutment plate moves along the length direction of the adjusting screw under the driving of the adjusting screw and the limiting of the sliding block and the adjusting groove, thereby adjusting the spacing between the upper abutment plate and the lower abutment plate and expanding the application range of the device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation between the bracket arc plate and the internal positioning assembly, it can protect the expansion joint during transportation and reduce the possibility of damage to the expansion joint;

[0025] 2. The setting of the abutment slope enables the flange to always fit tightly with the upper abutment plate and the lower abutment plate without any gap;

[0026] 3. The arrangement of the plug plate and the slot avoids the possibility of relative sliding of the bracket arc plate when connected, further improving the structural stability of the device, while also reducing the structural stress on the limit clamp plate and the clamp.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-7The present application is further described in detail. The embodiment of the present application provides a detachable transport structure for protecting an expansion joint, which has the effect of protecting the expansion joint 5 during transportation and reducing the possibility of damage to the expansion joint 5.

[0036] Example 1

[0037] Reference Figure 1 A detachable transport structure for protecting expansion joints includes a bracket arc plate 1, a limit plate group 2 and an internal positioning assembly 3. The bracket arc plate 1 is semi-cylindrical, and two bracket arc plates 1 are symmetrically arranged. Two groups of limit plate groups 2 are arranged on the outer arc wall of each bracket arc plate 1, and the limit plate group 2 includes two limit clamps 21. The limit clamps 21 include a first vertical portion 211 and a first horizontal portion 212. One end of the first horizontal portion 212 is vertically fixedly connected to one end of the first vertical portion 211, and the first vertical portion 211 is fixedly connected to the outer arc wall of the bracket arc plate 1. The two semi-cylindrical bracket arc plates 1 are spliced ​​together into a complete cylindrical structure. Two clamps 4 are commonly sleeved on the outside of the two bracket arc plates 1. The two clamps 4 are arranged one-to-one with the two groups of limit plate groups 2 on the same bracket arc plate 1, and the clamps 4 pass through the two first horizontal portions 212 in the limit plate group 2.

[0038] Reference Figure 2 and Figure 3 , two groups of inner positioning components 3 are arranged on the inner ring wall of the bracket arc plate 1, and the connection direction of the two groups of inner positioning components 3 is arranged parallel to the central axis direction of the bracket arc plate 1. The inner positioning component 3 includes an upper abutment plate 31 and a lower abutment plate 32, the upper abutment plate 31 is arranged above the lower abutment plate 32, and the upper abutment plate 31 and the lower abutment plate 32 are arranged at intervals. The upper abutment plate 31 includes a second vertical portion and a second horizontal portion, and one end of the second vertical portion is vertically fixedly connected to one end of the second horizontal portion. The lower abutment plate 32 includes a third vertical portion and a third horizontal portion, and one end of the third vertical portion is vertically fixedly connected to one end of the third horizontal portion. The second vertical portion and the third vertical portion are both fixedly connected to the inner arc wall of the bracket arc plate 1. An abutment slope 321 is arranged on the top surface of the third horizontal portion, and the longitudinal cross-sectional area of ​​the third horizontal portion gradually decreases along the direction away from the bracket arc plate 1.

[0039] Reference Figure 2 The expansion joint 5 includes two flanges 51 for connection and a bellows 52 arranged between the two flanges 51. When protecting the expansion joint 5, two semi-cylindrical bracket arc plates 1 are sleeved on the outside of the expansion joint 5, and the two bracket arc plates 1 together form a cylinder to surround the expansion joint 5. The two bracket arc plates 1 are connected to the outside of the two bracket arc plates 1 by two clamps 4, so as to achieve the connection and fixation of the two bracket arc plates 1. The clamp 4 passes between the corresponding two limit clamps 21, so as to prevent the clamp 4 from falling off from the bracket arc plate 1 during the connection process.

[0040] Reference Figure 2 and Figure 3 , the two flanges 51 at both ends of the expansion joint 5 are arranged in a one-to-one correspondence with the two groups of internal positioning components 3 on the bracket arc plate 1. The bottom surface of the second horizontal portion abuts the top surface of the flange 51, and the top surface of the third horizontal portion supports the bottom surface of the flange 51. The upper abutment plate 31 and the lower abutment plate 32 position the flange 51, which prevents the expansion joint 5 from moving up and down and left and right due to vibration during transportation, and reduces the possibility of damage to the expansion joint 5 during transportation. Since the top surface of the third horizontal portion is provided with an abutment slope 321, the abutment slope 321 abuts against the bottom edge of the flange 51. When the farah is inserted between the upper abutment plate 31 and the lower abutment plate 32, the lower abutment plate 32 can be in seamless contact with the bottom surface of the flange 51, further improving the stability of the connection structure.

[0041] The implementation principle of a detachable transport structure for protecting an expansion joint in Example 1 of the present application is as follows: when protecting the expansion joint 5, two semi-cylindrical bracket arc plates 1 are sleeved on the outside of the expansion joint 5, and two clamps 4 are used to fix the two bracket arc plates 1. The upper abutment plate 31 and the lower abutment plate 32 position the flange 51 to prevent the expansion joint 5 from shaking during transportation.

[0042] Example 2

[0043] Reference Figure 4-6 The difference between the second embodiment and the first embodiment is that the lower abutment plate 32 is slidably arranged with the inner arc wall of the bracket arc plate 1. Figure 7 The inner positioning assembly 3 further includes an adjusting screw 33, a mounting plate 34 and a sliding block 35. The sliding block 35 is fixedly connected to the side where the third vertical portion is in contact with the inner arc wall of the bracket arc plate 1. An adjusting groove 101 is provided on the inner arc wall of the bracket arc plate 1. The length direction of the adjusting groove 101 is parallel to the central axis of the bracket arc plate 1. The sliding block 35 is slidably arranged in the adjusting groove 101.

[0044] Reference Figure 5 and Figure 7 , the mounting plate 34 is fixedly connected to the inner arc wall of the bracket arc plate 1, the adjusting screw 33 is rotatably connected to the mounting plate 34, and the length direction of the adjusting screw 33 is parallel to the length direction of the adjusting slot 101. A threaded hole is provided at the bottom end of the lower abutment plate 32, and the top end of the adjusting screw 33 is threadedly connected to the lower abutment plate 32 through the threaded hole. An abutment rubber pad 6 is fixedly connected to the abutment slope 321. An insert plate 7 is fixedly connected to one of the end faces in the radial direction of the bracket arc plate 1, and a slot 102 corresponding to the shape of the insert plate 7 is provided on the other end face. When two bracket arc plates 1 are spliced ​​together, the insert plate 7 is inserted into the corresponding slot 102.

[0045] Reference Figure 5The bracket arc plate 1 includes an upper adjustment arc plate 103 disposed at the top and a lower adjustment arc plate 104 disposed at the bottom. A sliding plate 105 is fixedly connected to the bottom end of the upper adjustment arc plate 103, and the length direction of the sliding plate 105 is arranged parallel to the central axis direction of the bracket arc plate 1. A sliding groove 106 corresponding to the sliding plate 105 is opened at the bottom end of the lower adjustment arc plate 104, and the sliding plate 105 is slidably inserted in the sliding groove 106. A locking bolt 8 is threadedly connected to the lower adjustment arc plate 104, and the end of the locking bolt 8 extends into the sliding groove 106 and is tightly pressed against the sliding plate 105.

[0046] Reference Figure 5 and Figure 7 , for the expansion joint 5 whose flanges 51 at both ends are already connected to the external structure, its overall length is not easy to stretch or shorten. At this time, adjust the position of the sliding plate 105 in the sliding groove 106, and screw the locking bolt 8 to fix the position of the sliding plate 105. The setting of the sliding plate 105 and the sliding groove 106 realizes the adjustment of the overall length of the bracket arc plate 1, expanding the application range of the structure. The setting of the plug plate 7 and the slot 102 makes the two ends of the two bracket arc plates 1 always aligned in the length direction, avoiding the relative sliding of the two bracket arc plates 1 during the installation process.

[0047] Reference Figure 7 For flanges 51 of different thicknesses, the adjusting screw 33 is rotated, and the lower abutting plate 32 slides along the central axis direction of the bracket arc plate 1 under the driving of the adjusting screw 33 and the driving guidance of the sliding block 35 and the adjusting groove 101, thereby adjusting the distance between the upper abutting plate 31 and the lower abutting plate 32. The applicable scope of the device is further expanded. The setting of the abutting rubber pad 6 reduces the damage of the lower abutting plate 32 to the flange 51.

[0048] The implementation principle of a detachable transport structure for protecting expansion joints in Example 2 of the present application is as follows: for expansion joints 5 whose flanges 51 at both ends are already connected to external structures, it is not convenient to stretch or shorten their overall length. The position of the sliding plate 105 in the sliding groove 106 is adjusted, and the position of the sliding plate 105 is fixed. For flanges 51 of different thicknesses, the adjusting screw 33 is rotated to adjust the distance between the upper abutting plate 31 and the lower abutting plate 32.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
