Description

Technical Field

[0001] This utility model relates to the field of socket tube suspension technology, and in particular to a suspension device for moving socket tubes. Background Technology

[0002] Large-diameter reinforced concrete spigot and socket pipes are widely used in municipal drainage, water conservancy projects and other fields. One end of the spigot and socket pipe is a socket and the other end is a spigot. During installation, the spigot of one pipe needs to be inserted into the socket of another pipe.

[0003] In the current process of transporting large and heavy concrete socket pipes, steel wire ropes or nylon slings are commonly used to directly lift the pipes. However, during the lifting process, especially near the two ends of the concrete socket pipe, the steel wire ropes or nylon slings will generate huge concentrated stress on its edges, which can easily cause the two ends of the concrete socket pipe to be bumped, cracked or even broken, resulting in the scrapping of the pipe and economic losses. Therefore, a suspension device for moving socket pipes is proposed to solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a suspension device for moving socket pipes. The device is supported from the inside of the concrete socket pipe by a positioning arc plate, and the lifting force is entirely borne by the higher strength concrete socket pipe body. It has the advantages of preventing damage to the socket and spigot edges of the concrete socket pipe.

[0005] (II) Technical Solution This utility model provides a suspension device for moving a socket tube, including a square frame and a concrete socket tube. The concrete socket tube is located below the square frame. Two sliding plates are slidably connected to the inner side of the square frame. The bottom of each sliding plate is provided with a positioning mechanism to support the inner side of the concrete socket tube. The top of the square frame is provided with a spacing adjustment mechanism for installing the sliding plates and adjusting the spacing between the two sliding plates. Each of the four corners of the top of the square frame is provided with a lifting ring.

[0006] Preferably, the positioning mechanism includes a vertical plate disposed at the bottom of the sliding plate, a reinforcing plate disposed at the bottom of both sliding plates, the other end of the two reinforcing plates being connected to opposite sides of the two vertical plates respectively, a mounting plate disposed on opposite sides of the two vertical plates, a connecting block being detachably connected to the top of the two mounting plates, and a positioning arc plate disposed on the top of the two connecting blocks.

[0007] Preferably, the connecting block is detachably connected to the mounting plate by multiple connecting bolts, and at least one reinforcing rib is fixedly connected between the vertical plate and the mounting plate.

[0008] Preferably, the outer side of the positioning arc plate is provided with a rubber pad, and the positioning arc plate abuts against the inner side of the concrete socket pipe and is adapted to the inner side of the concrete socket pipe.

[0009] Preferably, the spacing adjustment mechanism includes an adjustment frame located at the top of the square frame. One side of the adjustment frame is rotatably connected to a bidirectional threaded rod extending into the interior of the adjustment frame via a bearing. Threaded blocks are threaded to the outer sides of both ends of the bidirectional threaded rod with opposite thread directions. The bottoms of the two threaded blocks are respectively connected to the top of the sliding plate. A handwheel is provided at the outer end of the bidirectional threaded rod located outside the adjustment frame. A support guide assembly is provided at the top of the square frame.

[0010] Preferably, the support guide assembly includes two support rods disposed at the top of the square frame, and the top of the sliding plate is provided with two sliding frames, which are slidably connected to the outside of the two support rods respectively.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This suspension device for moving socket pipes uses a positioning arc plate that contacts the inner wall of the concrete socket pipe, providing support from the inside of the pipe. The lifting force is entirely borne by the stronger concrete socket pipe body, preventing damage to the fragile socket and spigot edges. The distance between the two positioning mechanisms can be steplessly adjusted by rotating the bidirectional threaded rod, allowing it to accommodate socket pipes of different specifications within a certain length range. The positioning arc plate is detachable, allowing for replacement with a corresponding specification for concrete socket pipes of different inner diameters, further expanding the device's applicability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-5As shown, the present invention proposes a suspension device for moving a socket tube, including a square frame 1 and a concrete socket tube 2. The concrete socket tube 2 is located below the square frame 1. Two sliding plates 3 are slidably connected to the inner side of the square frame 1. The bottom of each sliding plate 3 is provided with a positioning mechanism 5 for supporting the inner side of the concrete socket tube 2. The top of the square frame 1 is provided with a spacing adjustment mechanism 6 for installing the sliding plates 3 and for adjusting the spacing between the two sliding plates 3. Each of the four corners of the top of the square frame 1 is provided with a lifting ring 7.

[0023] In this utility model, the square frame 1 is welded from high-strength steel, providing an installation foundation and structural rigidity for its internal components. The concrete socket pipe 2 can be positioned and supported by two sliding plates 3 and two sets of positioning mechanisms 5, ensuring the stability of the concrete socket pipe 2 when it is suspended. The spacing between the two sliding plates 3 can be adjusted by the spacing adjustment mechanism 6, thereby adjusting the spacing between the two sets of positioning mechanisms 5, which facilitates the suspension of concrete socket pipes 2 of different lengths. The four lifting rings 7 can be connected to the slings, so that the square frame 1 and the entire suspension device can be lifted by the four lifting rings 7.

[0024] In embodiment 1, the positioning mechanism 5 includes a vertical plate 51 located at the bottom of the sliding plate 3. The bottom of both sliding plates 3 is provided with a reinforcing plate 52. The other end of the two reinforcing plates 52 is connected to the opposite side of the two vertical plates 51 respectively. The opposite side of the two vertical plates 51 is provided with a mounting plate 53. The top of the two mounting plates 53 is detachably connected with a connecting block 54. The top of the two connecting blocks 54 is provided with a positioning arc plate 55.

[0025] The reinforcing plate 52 ensures the stability of the vertical plate 51 after installation and prevents the vertical plate 51 from tilting when suspending the concrete socket pipe 2. When suspending the concrete socket pipe 2, the spacing between the two positioning arc plates 55 is adjusted by the spacing adjustment mechanism 6 so that both positioning arc plates 55 enter the interior of the concrete socket pipe 2. At this time, the square frame 1 can be lifted by multiple lifting rings 7, thereby lifting the concrete socket pipe 2 by the two positioning arc plates 55.

[0026] The connecting block 54 is detachably connected to the mounting plate 53 by multiple connecting bolts 56. The connecting bolts 56 allow for quick installation and removal of the connecting block 54 and the positioning arc plate 55, thereby allowing for the replacement of positioning arc plates 55 with different inner diameters for concrete socket pipes 2 with different inner diameters, thus improving the applicability of the suspension device.

[0027] At least one reinforcing rib 57 is fixedly connected between the vertical plate 51 and the mounting plate 53. The reinforcing rib 57 improves the load-bearing strength of the mounting plate 53, thereby improving the load-bearing strength of the connecting block 54 and the positioning arc plate 55, and ensuring the stability of the positioning arc plate 55 when bearing the concrete socket pipe 2.

[0028] A rubber pad is provided on the outer side of the positioning arc plate 55. The positioning arc plate 55 abuts against the inner side of the concrete socket pipe 2 and is adapted to the inner side of the concrete socket pipe 2. The rubber pad can increase the friction between the positioning arc plate 55 and the concrete socket pipe 2. At the same time, the rubber pad can also protect the inner wall of the concrete socket pipe 2. The positioning arc plate 55 can provide stable support for the inner side of the concrete socket pipe 2, ensuring the stability of the concrete socket pipe 2 when suspended and preventing the concrete socket pipe 2 from shaking when suspended.

[0029] In embodiment 2, the spacing adjustment mechanism 6 includes an adjustment frame 61 located at the top of the square frame 1. One side of the adjustment frame 61 is rotatably connected to a bidirectional threaded rod 62 extending into the interior of the adjustment frame 61 via a bearing. Threaded blocks 63 are threaded to the outer sides of both ends of the bidirectional threaded rod 62 with opposite thread directions. The bottoms of the two threaded blocks 63 are respectively connected to the top of the sliding plate 3. A handwheel 64 is provided at the end of the bidirectional threaded rod 62 located outside the adjustment frame 61. A support guide assembly 65 is provided at the top of the square frame 1.

[0030] When the handwheel 64 is turned, it drives the bidirectional threaded rod 62 to rotate. The support and guide assembly 65 supports and guides the sliding plate 3, while preventing the sliding plate 3 and the threaded block 63 from rotating. When the bidirectional threaded rod 62 rotates, under the action of the thread thrust, it drives the two threaded blocks 63 to move to the opposite side or the opposite side. The two threaded blocks 63 then drive the two sliding plates 3 to move to the opposite side or the opposite side, thereby adjusting the distance between the two sliding plates 3.

[0031] In embodiment 3, the support guide assembly 65 includes two support rods 651 located at the top of the square frame 1, and two sliding frames 652 located at the top of the sliding plate 3. The two sliding frames 652 are slidably connected to the outside of the two support rods 651 respectively.

[0032] The sliding frame 652 can be installed on the sliding plate 3 by means of the support rod 651, ensuring the stability of the sliding plate 3 after installation. At the same time, it guides the movement of the sliding plate 3, making the movement of the sliding plate 3 more stable.

[0033] In embodiment four, a contact plate 4 is fixedly provided in the middle of the inner side of the square frame 1. When the square frame 1 moves downward to the limit position, the contact plate 4 contacts the top of the concrete socket pipe 2.

[0034] When suspending the concrete socket pipe 2, first suspend the square frame 1 above the concrete socket pipe 2, so that the two positioning arc plates 55 are located at both ends of the concrete socket pipe 2. When the square frame 1 moves downward to the limit position, the contact plate 4 abuts against the top of the concrete socket pipe 2. At this time, it is ensured that when the two positioning arc plates 55 move to the opposite side, the two positioning arc plates 55 can stably enter the interior of the concrete socket pipe 2. When the contact plate 4 abuts against the top of the concrete socket pipe 2, the outer side of the positioning arc plate 55 does not abut against the inner side of the concrete socket pipe 2.

[0035] Working principle: The suspension device for moving the socket pipe is used by first turning the handwheel 64, which drives the two sliding plates 3 to move to their maximum distance to opposite sides via the double-threaded rod 62. Then, the entire device is lifted by a crane and slowly lowered so that the contact plate 4 abuts against the top of the concrete socket pipe 2. At this time, the two positioning arc plates 55 are located at both ends of the concrete socket pipe 2. Next, turn the handwheel 64 in the opposite direction to make the two sliding plates 3 move towards each other, so that the positioning arc plates 55 of the two positioning mechanisms 5 are inserted into the pipe from both ends. The concrete socket pipe 2 can then be lifted and transported to the designated position. After that, the pipe is lowered smoothly, so that the contact plate 4 abuts against the top of the concrete socket pipe 2. At this time, the handwheel 64 can be turned to discharge the positioning arc plates 55 from the concrete socket pipe 2, thus completing one operation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
