[0001] This utility model relates to the field of segment hoisting technology, specifically a socket-type segment hoisting tool. Background Technology
[0002] In urban and underground engineering construction, tunnel segments play an indispensable role as a crucial component of the lining structure. Widely used in shield tunneling, tunnel segments are spliced together ring by ring to form a robust circular lining structure that withstands earth pressure, water pressure, and dynamic loads from train operation, ensuring the stability and safety of the tunnel. In large-scale projects such as mountain tunnels and river-crossing tunnels, tunnel segments are also fundamental to constructing a stable tunnel space; their quality and installation precision directly affect the success or failure of the entire project.
[0003] Existing devices mostly clamp the segments from the left and right when in use. After clamping, the segments may shake, move, or even fall off, which affects the personal safety of the workers. Therefore, a special lifting device for segments with a socket type is proposed. Utility Model Content
[0004] This utility model provides a special lifting tool for socket-type tunnel segments to solve the problem that most existing devices clamp the segments from the left and right sides during use, which can cause the segments to shake, move, or even fall off, thus affecting the personal safety of workers.
[0005] This utility model provides the following technical solution: a special lifting tool for socket-type tunnel segments, comprising two sets of clamping plates, and further comprising: clamping components disposed inside the two sets of clamping plates, each set of clamping components comprising a hydraulic rod, a lower pressure plate, and two sets of positioning rods; protective components disposed on one side of the two clamping plates, each set of protective components comprising two sets of female adhesive plates, two sets of female adhesive plates, and a protective pad; and several sets of grooves disposed on one side of the two sets of clamping plates, wherein four sets of positioning rods and two sets of hydraulic rods are fixedly connected to the inside of the grooves.
[0006] As a preferred embodiment of this utility model, both sets of hydraulic rods are disposed inside the two sets of clamping plates, and one end of each set of hydraulic rods is fixedly connected to a lower pressure plate. Both sets of lower pressure plates are slidably connected to two sets of positioning rods.
[0007] As a preferred technical solution of this utility model, four sets of female adhesive plates are all disposed on one side of two sets of clamping plates, and one side of each of the two sets of female adhesive plates is glued with a female adhesive plate, and one side of each of the four sets of female adhesive plates is fixedly connected with two sets of protective pads.
[0008] As a preferred technical solution of this utility model, the surfaces of the two sets of lower pressure plates are provided with two sets of sliding holes, and the four sets of positioning rods are slidably connected to the inside of the sliding holes.
[0009] As a preferred embodiment of this utility model, a positioning block is fixedly connected to one side of each of the two sets of clamping plates, and a first fixing rod is rotatably connected inside the top surface of each of the two sets of clamping plates.
[0010] As a preferred embodiment of this utility model, two sets of connecting rods are rotatably connected to the outer sides of the two sets of first fixed rods, and rotating rods are rotatably connected to the inner sides of the four sets of connecting rods.

[0013] Compared with the prior art, this utility model provides a special lifting tool for socket-type tunnel segments, which has the following advantages:
[0014] This socket-type segment lifting tool, through its clamping assembly, activates a hydraulic rod when clamping the segment. The movement of the hydraulic rod moves the lower pressure plate, and a positioning rod prevents the lower pressure plate from swaying. The movement of the lower pressure plate further clamps the segment, firmly fixing it in place and preventing it from swaying, rotating, or shifting during hoisting and transportation. It also provides reliable clamping force to prevent the segment from falling due to accidents, avoiding injury to personnel and equipment, and thus ensuring construction safety.
[0015] This socket-type segment lifting device, through the inclusion of protective components, moves the clamping plate during clamping, causing the protective pad to move as well. The protective pad comes into contact with the segment, providing cushioning and protection, reducing scratches and wear on the segment surface, and ensuring the appearance quality and structural integrity of the segment. After a period of use, the protective pad can be peeled off from the clamping plate, separating the female and female adhesive plates, allowing for replacement of the protective pad and preventing damage to the pad from affecting the protective effect of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 - Figure 4 This utility model discloses a special lifting tool for socket-type tunnel segments, including two sets of clamping plates 1, and further including: clamping components 2 disposed inside the two sets of clamping plates 1, which further clamp the tunnel segments through the clamping components 2, and each set of clamping components 2 includes a hydraulic rod 201, a lower pressure plate 202 and two sets of positioning rods 203; a protective component 3 disposed on one side of the two clamping plates 1, which further protects the tunnel segments through the protective component 3, and each set of protective components 3 includes two sets of female adhesive plates 301, two sets of female adhesive plates 302 and a protective pad 303; and several sets of grooves disposed on one side of the two sets of clamping plates 1, with four sets of positioning rods 203 and two sets of hydraulic rods 201 fixedly connected inside the grooves.
[0023] Specifically, both sets of hydraulic rods 201 are installed inside the two sets of clamping plates 1, and one end of each set of hydraulic rods 201 is fixedly connected to a lower pressure plate 202. Both sets of lower pressure plates 202 are slidably connected to two sets of positioning rods 203.
[0024] In this embodiment, the hydraulic rod 201 moves to drive the lower pressure plate 202 to move. When the lower pressure plate 202 moves, it clamps the top surface of the tube segment to fix it, causing the tube segment to fall off. The positioning rod 203 is used to limit the lower pressure plate 202 so that the lower pressure plate 202 can move smoothly.
[0025] Specifically, four sets of female adhesive plates 301 are all set on one side of two sets of clamping plates 1, and one side of each set of female adhesive plates 301 is glued with a female adhesive plate 302. One side of each set of female adhesive plates 302 is fixedly connected with two sets of protective pads 303.
[0026] In this embodiment, the protective pad 303 is used to protect the pipe segments and prevent wear on their surface. The cooperation between the sub-adhesive plate 302 and the mother adhesive plate 301 can fix the protective pad 303.
[0027] Specifically, each of the two sets of lower pressure plates 202 has two sets of sliding holes on its surface, and the four sets of positioning rods 203 are slidably connected inside the sliding holes.
[0028] In this embodiment, the sliding hole allows the lower pressure plate 202 to slide on the outside of the positioning rod 203, and the positioning rod 203 makes the lower pressure plate 202 move more smoothly.
[0029] Specifically, a positioning block 4 is fixedly connected to one side of each of the two sets of clamping plates 1, and a first fixing rod 5 is rotatably connected inside the top surface of each of the two sets of clamping plates 1.
[0030] Specifically, two sets of connecting rods 6 are rotatably connected to the outer sides of the two sets of first fixed rods 5, and rotating rods 7 are rotatably connected to the inner sides of the four sets of connecting rods 6.
[0031] In this embodiment, the rotating rod 7 allows the connecting rod 6 to rotate on its surface, thereby enabling the device to operate normally.
[0032] Specifically, the outer side of the rotating rod 7 is rotatably connected to a lifting ring 8, and the four sets of connecting rods 6 are internally fixedly connected to several sets of reinforcing rods 9.
[0033] Specifically, the rotating rod 7 is internally connected to a limiting rod 10, a sliding rod 11 is fixedly connected to one side of the limiting rod 10, and a second fixing rod 12 is overlapped and connected to one side of the limiting rod 10.
[0034] The working principle and usage process of this utility model are as follows: When clamping the pipe segment, the hydraulic rod 201 is activated. The movement of the hydraulic rod 201 drives the lower pressure plate 202 to move. The positioning rod 203 prevents the lower pressure plate 202 from shaking. The movement of the lower pressure plate 202 further clamps the pipe segment, which can firmly fix the pipe segment and prevent it from shaking, rotating or displacing during hoisting and transportation. At the same time, it can also provide reliable clamping force to prevent the pipe segment from falling due to accidental situations, avoid injury to personnel and equipment, and thus ensure the safety of construction.
[0035] During clamping, the clamping plate 1 moves, causing the protective pad 303 to move as well. The protective pad 303 moves and comes into contact with the tube segment. The protective pad 303 can play a role in buffering and protecting, reducing scratches and wear on the surface of the tube segment, and ensuring the appearance quality and structural integrity of the tube segment. After the protective pad 303 has been used for a period of time, it can be peeled off from the clamping plate 1, and the female adhesive plate 301 and the female adhesive plate 302 can be separated, so that the protective pad 303 can be replaced, thus avoiding damage to the protective pad 303 and affecting the protective effect of the device.
[0036] In summary, this socket-type segment lifting tool, through the setting of clamping component 2 and protective component 3, ensures safety during use and can also prevent segment wear.
