Description

Technical Field

[0001] This utility model relates to the field of civil engineering equipment technology, and in particular to a chain clamp device for pipe piles. Background Technology

[0002] Prestressed concrete pipe piles have advantages such as high bearing capacity, convenient prefabrication, rapid construction, and strong adaptability to geological formations, and are therefore widely used in foundation treatment in transportation civil engineering and building construction. When fixing, hoisting, connecting, and testing the bearing capacity of pipe piles, clamping devices are usually used as auxiliary components. These clamping devices can stably hold the pipe piles for subsequent work. However, existing clamping devices are composed of steel plates and angle steel of specific lengths, usually as an integrated steel ring. The length of the clamp needs to be determined according to the diameter at the installation location, using clamps of different heights and tower types. The lengths of the clamps vary, generally requiring custom manufacturing, which results in long design cycles and high labor costs. Furthermore, existing clamping devices are not suitable for rapid installation at different locations, lacking flexibility. Therefore, an adjustable diameter clamping structure is needed. However, current adjustable clamping structures cannot achieve proper locking during operation.

[0003] Therefore, based on customer feedback regarding the shortcomings of the existing device, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a chain clamp device for pipe piles that can flexibly adjust its length, adapt to pipe piles of different diameters, and achieve good locking.

[0005] The purpose of this utility model is achieved through the following technical solution: a chain clamp device for pipe piles, comprising an I-beam chain link, a buckle structure and a locking structure;

[0006] The I-beam chain link includes link A and link B; multiple links A and multiple links B are interleaved and connected together to form a long chain structure; the buckle structure includes fastener A and fastener B, fastener A is connected to link A and fastener B is connected to link B. Since fastener A and fastener B are movably inserted, link A and link B are movably connected via the buckle structure; the locking structure includes a socket and a plug; the socket and plug are respectively connected to the two ends of the long chain structure. The socket is provided with a mounting groove, and the plug is provided with a spring. After the plug is inserted into the mounting groove, it is locked in the mounting groove by the spring.

[0007] As a preferred technical solution of this application, the plug includes a central post, elastic plates and a spring; an elastic plate is provided on the upper and lower sides of the central post at a certain angle, and the tail ends of the upper and lower elastic plates are connected to the central post via a spring. When the elastic plates on both sides are pressed toward the central post, the spring is compressed and the plug is inserted into the mounting groove. Then the elastic plates are released and the springs are reset, thereby locking the elastic plates with the mounting groove.

[0008] As a preferred technical solution of this application, the plug further includes a mounting component, which is a concave structure and is connected to link A at the end of the long chain. At the same time, the other side of the mounting component is fixedly connected to the central post.

[0009] As a preferred technical solution of this application, a rectangular protrusion is provided on the lower part of the elastic sheet facing away from the central column, and grooves are provided on the upper and lower sides of the mounting groove in the socket. After the elastic sheet is inserted into the mounting groove, the rectangular protrusion is adapted to be inserted into the groove due to the spring's return extension.

[0010] As a preferred technical solution of this application, the end of the elastic sheet is provided with a pressure plate. After manually pressing the pressure plates on both sides to insert the plug into the mounting groove, the inner surface of the pressure plate is in contact with the bottom surface of the socket.

[0011] As a preferred technical solution of this application, the socket is provided with a magnet in the mounting groove. The magnet is respectively provided on the inner bottom surface of the mounting groove and the bottom surface of the two grooves. At the same time, magnetic components are also provided on the top of the central column, the rectangular protrusion, and the surface of the pressure plate, so as to further lock the plug and socket together.

[0012] As a preferred technical solution of this application, the chain link A has an upper mounting block, a lower mounting block and a support column; the support column is vertically connected to the two mounting blocks, and a first threaded hole is opened on the outer surface of the upper and lower mounting blocks. At the same time, one end of the fastener A has an external thread and can be fitted into the first threaded hole and tightened, and the other end of the fastener A is inserted into the fastener B.

[0013] As a preferred technical solution of this application, the inner sides of the upper and lower end faces of the chain link B are also provided with second threaded holes. One end of the fastener B has an external thread and is adapted to be screwed into the second threaded hole. The other end of the fastener B is provided with a spherical groove. At the same time, the free end of the fastener A is a spherical head, which can be adapted to be inserted into the spherical groove, thereby movably connecting the chain link A and the chain link B.

[0014] This utility model has the following advantages:

[0015] (1) The length can be flexibly adjusted to adapt to pipe piles of different diameters;

[0016] The existing integrated steel ring clamp structure is fixed and cannot be applied to pipe piles of various diameters. Custom-made clamps for various pipe diameters have long design cycles and high labor costs. Therefore, this solution uses fasteners A and B to connect the I-beam chain links A and B to form a long chain as the main body of the clamp. Changing the clamp length only requires disassembling or adding links in the middle section of the chain to adjust the diameter. This is convenient for loading and unloading and has lower labor costs.

[0017] (2) Achieve good locking;

[0018] This design incorporates a plug with a spring and a socket that is compatible with the insertion. The plug has a rectangular protrusion that aligns with a groove in the socket to provide a locking mechanism. After the plug is inserted, the spring engages with the spring to lock it in place. Furthermore, a magnet is placed between the plug and socket to further assist in locking them together. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0029] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes a chain clamp device for pipe piles to solve the problem.

[0032] See Figures 1 to 8 The proposed implementation scheme provides a chain clamp device for pipe piles, comprising an I-beam chain link, a locking structure, and a snap-fit ​​structure.

[0033] Among them, see Figures 1-4 The I-beam chain includes link A1 and link B2, and the support of link A1 is shorter than the support of link B2. A single link A1 and link B2 are movably connected by a snap-fit ​​structure. That is, multiple links A1 and multiple links B2 are interleaved and connected together to form a long chain structure. The tail end of the long chain structure is link A1.

[0034] Among them, see Figure 5 The buckle structure includes fastener A3 and fastener B4, which are movably connected to each other for easy installation and disassembly. Fastener A3 is connected to link A1 and fastener B4 is connected to link B2.

[0035] Among them, see Figure 2 and Figures 6-7 The locking structure includes a socket and a plug that are mutually inserted and locked together. The socket and the plug are respectively connected to the tail end of the long chain structure. The long chain structure is locked together by the mutual connection of the socket and the plug to form a chain clamp. The socket is provided with a mounting groove 12 for the plug to be inserted. At the same time, the plug is provided with a spring 8. After the plug is inserted into the mounting groove 12, it is locked in the mounting groove 12 by the spring 8.

[0036] During installation, first connect multiple chain links A1 and B2 to fasteners A3 and B4 respectively. Then, insert fasteners A3 and B4 to form a long chain. At the same time, insert the plug into the mounting slot 12 of the socket. At this time, the spring 8 is in a compressed state. After the plug is fully inserted, remove the pressure of the spring 8 and the spring 8 will return to its original position. The plug will be locked in the mounting slot 12 by the action of the spring 8.

[0037] Currently available clamping structures are generally one-piece steel ring structures. While simple, they lack flexibility and cannot adapt to pipe piles of different diameters. Customizing clamps of various heights, diameters, and tower shapes is cumbersome and time-consuming. Many designs now feature segmented clamping structures, but their locking function is somewhat reduced compared to the one-piece steel ring. Therefore, a clamping structure is needed that allows for flexible diameter adjustment and effective locking. Based on these issues, this solution designs a chain clamping device for pipe piles. This solution achieves simple diameter adjustment by connecting individual chain links A1 and B2 via a snap-fit ​​structure. When the clamping diameter needs to be shortened, only one or several chain links need to be removed; to increase the overall length of the clamp, only chain links need to be added in the middle section. It is very simple and convenient. A plug and socket connection ensures effective locking.

[0038] In this embodiment, see Figures 1-2 and Figures 6-7 For the locking structure; the plug and socket in the locking structure are respectively connected to the chain links A1 at the tail ends of the long chain structure; the plug includes a central post 6 and elastic plates 7 opened on the upper and lower sides of the central post 6, as well as a spring 8; the central post 6 is a rectangular post, and elastic plates 7 are connected to the upper and lower sides of the central post 6 at a certain acute angle. Only one end of the elastic plate 7 is fixed to one end of the central post 6, and the elastic plate 7 can be bent; and a spring 8 is installed between the tail of the elastic plate 7 on the upper and lower sides and the central post 6. The spring 8 is perpendicular to the central post 6 and is connected to a mounting piece at the other end of the central post 6. The mounting piece is a concave block, which is connected to the tail end of the long chain.

[0039] It should be noted that when the two elastic pieces 7 are pressed and pressure is applied to the elastic pieces 7 on both sides toward the central post 6, the spring 8 is compressed, which allows the plug to be inserted into the mounting groove 12 of the socket. After the elastic piece 7 of the plug is inserted into the mounting groove 12, the pressure is released and the elastic piece 7 is released, and the spring 8 returns to its original position, thereby locking the elastic piece 7 with the mounting groove 12.

[0040] Furthermore, a rectangular protrusion 9 is provided on the outer side of the elastic piece 7 (the rectangular protrusion 9 faces outwards away from the central post 6). At the same time, grooves are provided on the upper and lower sides of the mounting groove 12 of the socket. The grooves are perpendicular to the mounting groove 12. After the elastic piece 7 is inserted into the mounting groove 12, the rectangular protrusion 9 is inserted into the groove due to the return extension of the spring 8. At the same time, a pressure plate 10 is provided at the free end of the elastic piece 7 (the pressure plate 10 also faces outwards away from the central post 6). After the plug is inserted into the mounting groove 12 by manually pressing the pressure plates 10 on both sides, the inner surface of the pressure plate 10 is in contact with the bottom surface of the socket, and the plug is fully inserted into the socket. When it is necessary to remove the plug, simply press the pressure plate 10 to retract the elastic piece 7, and the rectangular protrusion 9 will exit from the groove, so that the plug can be removed, which is convenient for installation and disassembly.

[0041] Furthermore, a magnet 11 is provided in the mounting groove 12 inside the socket. The magnet 11 is respectively set on the inner bottom surface of the mounting groove 12 and the bottom surface of the two grooves. At the same time, magnetic elements 13 are also provided on the top of the central post 6, the rectangular protrusion 9, and the surface of the pressure plate 10. After the plug is inserted into the socket, the magnet 11 and the magnetic element 13 at the corresponding positions attract and stick together, so that the socket and the plug are well locked.

[0042] In this embodiment, see Figures 1-5 For the I-beam chain link; both link A1 and link B2 are I-shaped. Link A1 includes an upper mounting block and a lower mounting block, which are vertically connected by a support column. The outer surfaces of the upper and lower mounting blocks of link A1 have first threaded holes, and one end of fastener A3 has an external thread 14. Fastener A3 and link A1 are connected by screwing. Link B2 also has an upper mounting block, a lower mounting block, and a support column. The inner surfaces of the upper and lower mounting blocks of link B2 have second threaded holes. One end of fastener B4 has an external thread 14 and is adapted to be screwed into the second threaded hole, that is, fastener B4 and link B2 are also connected by screwing. Fastener A3 and fastener B4 are adapted to be inserted into each other. The free end of fastener A3 is a ball head 5, and the free end of fastener B4 is provided with a spherical groove. The ball head 5 is adapted to be inserted into the spherical groove, thereby movably connecting link A1 and link B2.

[0043] It should be noted that the threaded holes on the upper and lower mounting blocks are respectively opened at the four corners of the mounting block surface. That is, each link A1 and link B2 is connected by four fasteners A3 and four fasteners B4. At the same time, the mounting plate is arc-shaped to avoid collision and friction between the links.

[0044] Meanwhile, in this solution, each link is connected by a ball joint, allowing each link to rotate freely. This avoids the use of bolt connections, making it more flexible and easier to assemble and disassemble.

[0045] In the use of this clamp, multiple chain links A1 and B2 are first connected to fasteners A3 and B4 respectively. Then, fasteners A3 and B4 are inserted to form a long chain that can rotate flexibly. After the plug is inserted into the mounting slot 12 of the socket, the spring 8 is in a compressed state. After the plug is fully inserted, the pressure of the spring 8 is removed, and the spring 8 returns to its original position. The rectangular protrusion 9 of the plug is inserted into the groove by the action of the spring 8, thereby locking the plug in the socket.

[0046] When fixing and hoisting pipe piles, as well as fixing pipe piles together, clamping devices are usually used as auxiliary components to stably hold the pipe piles for subsequent work. However, the current clamping device is a one-piece steel ring, which cannot adapt to pipe piles of different diameters. The currently used split clamping device is not good enough for the one-piece steel ring, and it is easy to loosen the clamping. Therefore, this solution uses a long chain composed of I-beam chain links A1 and B2 connected by a snap-fit ​​structure as the main body of the clamping device. It can achieve the effect of adjusting the diameter. When it is necessary to change the length of the clamping device, the middle section of the chain link can be disassembled or added, which is very convenient. In addition, this solution is designed with a plug and a socket. The plug has a rectangular protrusion 9 that aligns with the groove in the socket for locking. At the same time, an elastic piece 7 is provided to cooperate with a spring 8. After the plug is inserted, the spring 8 presses against the elastic piece 7 to further lock it. In addition, a magnet 11 is provided to assist in locking the socket and plug.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
