In the process of prefabricating segments in the workshop, the lifting and transfer of the formed segments is often involved.

[0003] A Chinese patent document with authorization announcement number CN218062326U discloses a shield machine segment lifting device.

[0028] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0029] like Figure 1-Figure 5 As shown, a prefabricated pipe segment lifting device includes a load-bearing component 1 that can provide an installation position for other components so that the device can stably lift the pipe segment, a fixing component 2 that can contact pipe segments of various sizes and types at multiple points is arranged below the load-bearing component 1, and a suspension component 3 that can drive the load-bearing component 1 to rise and fall stably is arranged above the load-bearing component 1.

[0030] In this embodiment: the load-bearing component 1 includes a load-bearing frame 101, and an anti-slip pad 102 is fixedly connected to the lower side of the load-bearing frame 101; the fixed component 2 and some parts of the suspension component 3 are installed through the load-bearing frame 101, and the lifting and lowering of the suspension component 3 are stably transmitted to the fixed component 2, and the anti-slip pad 102 contacts some parts of the fixed component 2 to limit the movement of some parts of the fixed component 2 through its own friction and slight deformation.

[0031] In this embodiment, the fixing assembly 2 includes an abutment member that can contact the pipe segment at multiple points, a suspension member that can flexibly adjust the position of the abutment member within a certain range, and a limiting member that can keep the abutment member at a specific position when not interfered by external forces. The limiting member includes a vertical cylinder 201 fixedly connected to the load-bearing frame 101, a top cover 202 is fixedly connected to the upper end of the vertical cylinder 201, a vertical rod 203 is arranged between the vertical cylinder 201 and the top cover 202, and a first spring 204 is movably connected to the outer side of the vertical rod 203. The suspension member includes a first spring 204 arranged at the first A lifting frame 205 is provided below the spring 204, a second spring 206 is provided inside the lifting frame 205, a cross bar 207 is provided on one side of the second spring 206, the suspension member further comprises a vertical bar 208 movably connected to both sides of the load-bearing frame 101, the abutment member comprises a support arm 209 provided between the cross bar 207 and the vertical bar 208, a T-shaped frame 210 is movably connected to the lower end of the support arm 209, a sling 211 is movably connected between the front and rear ends of the same T-shaped frame 210, and an anti-slip sleeve 212 is fixedly connected to the outer side of the sling 211;

[0032] The vertical tube 201, the vertical rod 203, and the cross bar 207 are all slidably connected to the lifting frame 205, the cross bar 207 is rotatably connected to the support arm 209, the load-bearing frame 101 and the support arm 209 are rotatably connected to the vertical rod 208, and the support arm 209 and the sling 211 are rotatably connected to the T-shaped frame 210;

[0033] The lifting frame 205 is installed under the load-bearing frame 101 through the vertical tube 201, and the vertical rod 203 is fixed in the vertical tube 201 through the top cover 202. The movable range of the lifting frame 205 on the vertical tube 201 is limited by the vertical rod 203 and the first spring 204. The first spring 204 can also make the lifting frame 205 tend to move away from the top cover 202 when there is no external force. The lifting frame 205 drives the second spring 206 and the cross bar 207 to rise and fall together, and the lifting frame 205 drives the second spring 206 and the cross bar 207 to rise and fall together. The spring 206 causes the cross bar 207, which is not subjected to external force, to tend to move away from the vertical bar 203. The cross bar 207 and the vertical bar 208 jointly limit the movable range of the support arm 209 in the device. The sling 211 is installed through a T-shaped frame 210 installed at one end of the support arm 209, and the sling 211 can be made to hang vertically. The anti-slip sleeve 212 replaces the sling 211 to contact the pipe segment, so as to increase the friction between the pipe segment and the device and prevent the sling 211 from damaging the pipe segment.

[0034] In this embodiment: the suspension assembly 3 includes lifting ears 301 fixedly connected to the front and rear sides of the load-bearing frame 101, and rope buckles 302 are fixedly connected to the lifting ears 301, and lifting rings 303 are arranged between the rope buckles 302; it is connected to a lifting device such as an overhead crane through the lifting rings 303, and the lifting force from the lifting rings 303 is equally divided in different directions through the rope buckles 302 and the lifting ears 301 and then transmitted to the load-bearing frame 101, so as to realize stable horizontal lifting of the load-bearing frame 101.

[0035] Working principle: When the device is installed and used for lifting the prefabricated hydraulic pipe segment, the lifting ring 303 is connected to the overhead crane and other lifting equipment, and when the device is moved to the center position at an appropriate height above the pipe segment to be lifted, the anti-skid sleeve 212 is pulled so that the two anti-skid sleeves 212 can respectively hold one end of the pipe segment, and then the support arm 209 can be rotated relative to the vertical rod 208 and the vertical rod 208 can be rotated relative to the load-bearing frame 101 according to the size of the pipe segment, so that the upper end of the support arm 209 moves up with the lifting frame 205 and other parts belonging to the suspension parts, until the upper end of the support arm 209 abuts against the anti-skid pad 102 and the two T-frames 210 are appropriately spaced, and then The device can be slightly lifted by the lifting equipment to gradually tighten the sling 211. At this time, the upper end of the support arm 209 is subjected to the friction of the anti-skid pad 102, and the lower end of the support arm 209 is subjected to the gravity of the pipe segment transmitted to it by the T-frame 210 and other components. Therefore, the support arm 209 can be locked in the position of the device, so that the two slings 211 can lift up both ends of the pipe segment vertically upward or in a direction overlapping with the outer radius of the pipe segment at a spacing suitable for the size of the pipe segment. Furthermore, due to the friction between the anti-skid sleeve 212 and the pipe segment, the sling 211 in a vertical state can be prevented from slipping relative to the pipe segment during lifting, thereby ensuring the stability of the pipe segment lifted by the device.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
