Description

Technical Field

[0001] This utility model relates to the field of gripping equipment, specifically a magnetic gripping device for pipe segments. Background Technology

[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction. They form the innermost barrier of the tunnel, resisting soil pressure, groundwater pressure, and other special loads. TBM segments are the permanent lining structure of shield tunnels, and their quality directly affects the overall quality and safety of the tunnel, influencing its waterproofing and durability.

[0003] Current magnetic segment grasping devices, as described in patent CN216110775U, include two opposing walking beams. A connecting crossbeam is fixedly connected to one end of the two walking beams on opposite sides. An actuating part is slidably connected to the outer side of the two walking beams. A lifting part is fixedly connected to the side of the actuating part near the connecting crossbeam. A fine-tuning part is rotatably connected to the bottom end of the lifting part. A magnetic attraction part is fixedly connected to the bottom end of the fine-tuning part.

[0004] Regarding the aforementioned technologies, the inventors believe that the electromagnetic chuck generates magnetism to pick up the tube segments. However, the fixed curvature of the bottom of the electromagnetic chuck results in fewer contact points between the electromagnetic chuck and the tube segments when picking up tube segments with different curvatures. This makes the tube segments prone to shaking during the picking and moving process, making it difficult for the entire device to stably and magnetically grasp tube segments with different curvatures.

The output ends of two sets of the second hydraulic rods are fixedly connected to the movable plate. A rotating shaft is fixedly fixed through the interior of the rotating plate. Connecting beams are symmetrically rotatably connected to the outer side of the rotating shaft. A stepper motor is fixedly connected to one side of the connecting beam away from the rotating plate.

[0013] As a further embodiment of this utility model: fixing rings are fixedly connected to the opposite sides of the two sets of connecting beams, and columns are symmetrically fixedly connected to the bottom of the two sets of fixing rings.

[0014] As a further embodiment of this utility model: both sides of the rotating plate are symmetrically connected to guide wheels, and the guide wheels on both sides are in contact with the fixed rings on both sides respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With the above-described structure, this invention, through the cooperation of the second hydraulic rod, spring, sliding column, and first hydraulic rod, allows for the gripping of pipe segments simply by placing the pipe segment below each set of electromagnets. Then, the second hydraulic rod is activated, causing the moving plate and each set of electromagnets to move downwards until they contact the pipe segment to be gripped. The electromagnets are then energized, generating magnetism that attracts them to the steel pipe segment. Next, the first hydraulic rods on both sides are activated, causing the clamping plates on both sides to move relative to each other until they clamp and fix the sliding columns, thus restricting their movement. This ensures that when magnetically gripping pipe segments of different curvatures, each set of electromagnets can contact and attract the pipe segment, thereby achieving stable magnetic gripping of pipe segments with varying curvatures.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4 A magnetic gripping device for pipe segments includes a suction mechanism 1. The suction mechanism 1 includes a movable plate 101. Multiple sliding posts 102 are evenly slidably inserted through the center of the movable plate 101. An electromagnet 103 is fixedly connected to the bottom of each set of sliding posts 102. The sliding posts 102 guide the up-and-down movement of the electromagnets 103. When energized, the electromagnets 103 attract the pipe segments using magnetism. Guide rods 104 are symmetrically fixedly connected to both sides of the top of each set of electromagnets 103. Each set of guide rods 104 slides through the movable plate 101, further guiding the up-and-down movement of the electromagnets 103.

[0025] Each set of guide rods 104 has a limit block 106 fixedly connected to its top. The limit block 106 is used to limit the sliding of the guide rod 104. Each set of guide rods 104 has a spring 105 sleeved on its outer side. The two ends of each spring 105 are fixedly connected to the electromagnet 103 and the moving plate 101, respectively. The spring 105 is used to push the electromagnet 103 downward using its elasticity, so that all sets of electromagnets 103 can maintain the same horizontal height when the entire device is not in use.

[0026] A fixed base 107 is symmetrically fixedly connected to the top of the movable plate 101. Multiple reinforcing ribs 108 are evenly fixedly connected to the opposite sides of the two sets of fixed bases 107. Each set of reinforcing ribs 108 is fixedly connected to the movable plate 101. The reinforcing ribs 108 are used to further connect and fix the fixed bases 107 and the movable plate 101, thereby improving the connection stability between the fixed bases 107 and the movable plate 101. A first hydraulic rod 109 is symmetrically fixedly connected inside each set of fixed bases 107. Clamping plates 110 are fixedly connected to the output ends of the first hydraulic rods 109 on both sides. The two sets of clamping plates 110 are respectively located on both sides of the sliding column 102. The first hydraulic rods 109 can drive the clamping plates 110 to move during operation, allowing the two sets of clamping plates 110 to move and clamp and fix each set of sliding columns 102, thereby restricting the movement of the sliding columns 102 and the electromagnet 103.

[0027] The top of the movable plate 101 is symmetrically and fixedly connected with guide rails 111. Both sides of the guide rails 111 are slidably connected to two sets of clamping plates 110. The guide rails 111 guide the sliding of the clamping plates 110. The adjustment mechanism 2 includes a rotating plate 201 positioned above the movable plate 101. Second hydraulic rods 202 are symmetrically fixed through the interior of the rotating plate 201. The output ends of both sets of second hydraulic rods 202 are fixedly connected to the movable plate 101. The second hydraulic rods 202 can drive the movable plate 101 and each set of electromagnets 103 to move up and down, thereby adjusting the height of the electromagnets 103. A rotating shaft 206 is fixed through the interior of the rotating plate 201. The rotating shaft 206 drives the rotating plate 201 to rotate during rotation.

[0028] A connecting beam 204 is symmetrically rotatably connected to the outer side of the rotating shaft 206. A fixing ring 203 is fixedly connected to the opposite sides of both sets of connecting beams 204. A column 208 is symmetrically fixedly connected to the bottom of each of the two sets of fixing rings 203. The fixing rings 203 and columns 208 provide support for the connecting beams 204. Guide wheels 207 are symmetrically rotatably connected to both sides of the rotating plate 201. The guide wheels 207 contact the fixing rings 203 on both sides. The guide wheels 207 guide the rotation of the rotating plate 201 as it rotates and rolls along the inner wall of the fixing rings 203. A stepper motor 205 is fixedly connected to the side of one set of connecting beams 204 away from the rotating plate 201. The output end of the stepper motor 205 is fixedly connected to one end of the rotating shaft 206. The stepper motor 205 drives the rotating shaft 206 to rotate during startup.

[0029] In use, the steel pipe segment to be magnetically grasped is placed below each set of electromagnets 103. Then, the second hydraulic rod 202 is activated, causing the moving plate 101 and each set of electromagnets 103 to move downwards until all sets of electromagnets 103 are in contact with the steel pipe segment. Afterwards, each set of electromagnets 103 is energized, generating magnetism that attracts them to the steel pipe segment. Then, the first hydraulic rods 109 on both sides are activated, causing the clamping plates 110 on both sides to move relative to each other until the clamping plates 110 clamp and fix each set of sliding columns 102, thus restricting their sliding. The column 102 and each set of electromagnets 103 move, and then the second hydraulic rod 202 is activated again, so that the second hydraulic rod 202 can drive the moving plate 101 and each set of electromagnets 103 to move upward, thereby moving the steel pipe segments held by each set of electromagnets 103, thus realizing the gripping of the pipe segments. When it is necessary to adjust the angle of the pipe segments during the installation process, the stepper motor 205 can be activated, so that the stepper motor 205 can drive the rotating shaft 206 and the rotating plate 201 to rotate when it starts working. When the rotating plate 201 rotates, it can drive the second hydraulic rod 202 and electromagnets 103 to rotate accordingly, thereby driving the steel pipe segments held by each set of electromagnets 103 to rotate accordingly, so as to adjust the angle of the steel pipe segments.

They are not intended to limit the present utility model in any way.
