Description

Technical Field

[0001] The utility model relates to the technical field of mechanical communication channel construction, in particular to a device for pipe segment hoisting. Background Art

[0002] At present, the vertical transportation of the pipe segments of the mechanical communication channel is completed by a gantry crane, which moves parallel to the tunnel direction. The pipe segments are loaded and unloaded and vertically lifted by the gantry crane. During the lifting process of the pipe segments, the pipe segments are unstable, and there are problems such as pipe segment swinging and shaking. In severe cases, the pipe segments will overturn to one side, causing damage to the pipe segments or other equipment and materials, and even injuring nearby construction personnel, thus affecting the economy and safety of the entire communication channel construction. At present, the construction technology and measures for maintaining the stability of pipe segment lifting are generally carried out from the aspects of strictly ensuring the strength and stability of the pipe segment lifting holes, controlling the lifting speed, and having skilled workers perform lifting operations, but the effect is poor and cannot solve the problem of unstable pipe segments well.

[0003] The invention patent with the existing publication number CN110171767A discloses a clamping mechanism for pipe segment hoisting, including a crossbeam, a first clamping mechanism and a second clamping mechanism, wherein the first clamping mechanism and the second clamping mechanism are respectively located on both sides of the lower end of the crossbeam, and a lifting ring is fixedly connected to the middle position of the upper end of the crossbeam, and horizontally parallel positioning threaded holes are provided at the middle position of the outer surfaces of the front and rear ends of the crossbeam, and positioning bolts are penetrated through the two groups of front and rear corresponding threaded holes, and a slot is provided on the outer surface of the lower end of the crossbeam, and a fixing block is welded at the middle position of the outer surface of the lower end of the crossbeam. Although the clamping angle of the clamping mechanism can be accurately controlled, the firmness of the clamping can be improved, and the pipe segment can be avoided from being damaged, and the clamping mechanism can be adjusted according to pipe segments of different sizes, the entire device is complicated to set up, and there are certain risks and hidden dangers in using a motor to control the clamping. Therefore, it is urgent to propose a device with a simple structure for pipe segment hoisting. Summary of the invention

[0036] See also Figure 1-Figure 6 The utility model provides a structural schematic diagram of an embodiment of a device for lifting a pipe segment, wherein the device includes a mounting assembly, a lifting ring 1 arranged on the mounting assembly, and a lifting assembly connected to the lifting ring 1.

[0037] like Figure 1-5 As shown, the installation assembly includes a steel beam 3 and a plurality of bolts 2. The steel beam 3 is detachably connected to the lifting holes of the pipe segment 8 through the plurality of bolts 2. Preferably, the steel beam 3 is provided with a thread groove matching the bolt 2. The steel beam 3 is also provided with a detachable lifting ring 1. The lifting ring 1 is arranged between the plurality of bolts 2. The arrangement of the plurality of bolts 2 realizes the effective fixation of the steel beam 3 and the pipe segment 8, thereby improving the firmness of the lifting ring 1. The thread grooves on both sides of the steel beam 3 correspond to the positions of the lifting holes of the pipe segment 8, have the same specifications, and both match the bolts 2.

[0038] Furthermore, if Figure 2As shown, the lifting assembly includes a rotating joint 6 and a connecting rod 7 and a hook 5 connected to the upper and lower ends of the rotating joint 6 respectively. The hook 5 is used to match and connect with the lifting ring 1, and then the lifting ring 1 with different inner diameters can be replaced to adapt to the hook 5 of different specifications, which is conducive to reducing the shaking during transportation. The rotating joint 6 is used to control the rotation of the hook 5, and the connecting rod 7 is used to connect with the external power assembly. Preferably, the connecting rod 7 is a telescopic rod, so as to adjust the height of the hoisted pipe segment, so that the center of gravity of the pipe segment 8 can be lowered relative to the hook, and the possibility of overturning can be further reduced. At the same time, the rotating joint 6 includes a hemispherical groove in the upper part and a sphere in the lower part. The sphere can rotate in all directions in the hemispherical groove, so that the hook 5 can rotate in all directions, which is convenient for hooking into the lifting ring 1. And the rigid steel beam and telescopic rod are used instead of the flexible iron chain in general to improve stability, reduce the swaying and shaking of the pipe segment, and reduce the possibility of overturning.

[0039] Furthermore, if Figure 3 , Figure 6 As shown, a rubber cushion layer 4 is also provided between the steel beam 3 and the pipe segment 8. Specifically, in actual application, the upper side of the steel beam 3 is set as a plane, and the lower side of the steel beam 3 is set as a curved surface adapted to the surface of the pipe segment 8 and provided with a rubber cushion layer 4. During the rotation process, the rubber cushion layer 4 is pressed tightly against the concrete pipe segment 8. Since there is an extra layer of rubber cushion layer 4 between the hoisting device and the concrete pipe segment 8, the rubber cushion layer 4 can effectively prevent rigid contact between them, thereby avoiding damage to the concrete pipe segment 8 during the hoisting process.

[0040] Furthermore, if Figure 3 As shown, each bolt 2 is also provided with an exhaust passage 9. Specifically, a vertical blind hole is provided at the bottom end of each bolt 2 and a transverse through hole is provided at the head thereof, and the exhaust passage 9 is composed of the through hole and the blind hole. The provision of the exhaust passage allows the bolt 2 to effectively remove the air in the hoisting hole during the rotation and tightening process, making it easier to rotate and install the bolt.

[0041] Furthermore, in actual application, the steel beam 3 is detachably connected to the lifting hole of the pipe segment 8 through two bolts 2. And the lifting ring 1 is centrally arranged between the two bolts 2. Figure 4 shown.

[0042] Furthermore, in actual application, the telescopic rod is composed of three telescopic units controlled by hydraulic pressure, and the telescopic operation is controlled by hydraulic pressure, and the telescopic operation can be freely controlled by the operator according to the height requirement.

[0043] Furthermore, in actual application, the steel cross beam 3 is placed on the corresponding position of the pipe segment 8 so that the threaded grooves on both sides of the steel cross beam 3 correspond to the two lifting holes on one side of the pipe segment 8, and then the bolts 2 in the device are rotated and tightened into the two lifting holes of the pipe segment 6, and after the bolts 2 connect the steel cross beam 3 and the pipe segment 8, the eye bolt 1 is rotated and tightened into the middle threaded groove of the steel cross beam 3. At this time, the telescopic rod 7 is controlled to extend and retract so that the hook 5 reaches the specified height, and then the hook 5 is hooked into the lifting ring of the eye bolt 1 by rotating the rotating joint 6 to lift the pipe segment 8. At the same time, at least two sets of devices for lifting the pipe segment can be provided to realize the lifting of the pipe segment, as shown in the following figure. Figure 6 shown.

[0044] In the above embodiments, those skilled in the art may adopt the existing technology for software control, and the present utility model only protects the structure of the device for segment hoisting and the mutual connection relationship.

[0045] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
