[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0027] like Figure 1 and Figure 2 As shown, the pipe lifting device 100 of the embodiment of the utility model includes a hanging frame 1 and a limiting frame 2. The hanging frame 1 has a connecting portion for connecting a lifting device. The limiting frame 2 and the hanging frame 1 form a receiving groove 121 for the pipe 200 to pass through. The limiting frame 2 is movably connected to the hanging frame 1 to adjust the size of the receiving groove 121.
[0028] The pipe lifting device 100 of the embodiment of the utility model can insert the multiple pipes 200 into the receiving groove 121 when lifting multiple pipes 200 at the same time, and adjust the size of the receiving groove 121 by the limiting frame 2 so that the receiving groove 121 matches the size of the multiple pipes 200 that need to be lifted. The groove walls of the receiving groove 121 can limit the pipe 200 so that the multiple pipes 200 are stably placed in the receiving groove 121. Therefore, the stability and safety of the lifting of the pipe 200 can be improved. Even if the pipe 200 shakes during the lifting process, the pipe 200 and the lifting device are relatively stable and not easy to slip.
[0029] Alternatively, if Figure 2 As shown, the connecting portion is a hanging ring 11 , and the hanging ring 11 is welded to the top of the hanging frame 1 .
[0030] The lifting ring 11 can be connected to the hook of a lifting device, so as to achieve lifting and transportation of the pipeline 200.
[0031] As an example, Figure 1 As shown, there are two groups of pipeline lifting devices 100, which are arranged at intervals along the length direction of the pipeline 200. Lifting ropes are passed through the two lifting rings 11, and the hooks of the lifting equipment can be connected to the lifting ropes.
[0032] Of course, in other embodiments, the number of pipeline hoisting devices 100 may also be set to more than two groups to improve the stability and safety of the pipeline 200 hoisting.
[0033] In some embodiments, the hanging frame 1 includes a frame 12 and a mounting frame 13, the frame 12 and the mounting frame 13 form a frame opening, the limit frame 2 is arranged at the frame opening, the limit frame 2 and the frame 12 form a receiving groove 121, and the mounting frame 13 is provided with a stop assembly 3 for stopping the limit frame 2, and the mounting frame 13 is hinged to the frame 12.
[0034] Through the above arrangement, the abutment assembly 3 can apply pressure to the limiting frame 2 , so that the abutment assembly 3 tightly abuts against the pipe 200 , thereby improving the stability of the plurality of pipes 200 in the receiving groove 121 .
[0035] In addition, by hingedly connecting the mounting frame 13 to the frame 12, when placing the pipe 200 into the receiving groove 121 or taking it out from the receiving groove 121, the mounting frame 13 can be opened relative to the frame 12, and the limiting frame 2 can be taken out. The construction personnel can take out the pipe 200 along the opening of the frame 12, which makes the operation more convenient.
[0036] As an example, Figure 2 and Figure 3 As shown, the frame 12 is in a "U" shape, and the frame 12 has an opening upward, and the mounting frame 13 is in a rectangular plate shape. The mounting frame 13 is arranged on the upper side of the frame 12, and can block the opening on the upper side of the frame 12, thereby forming a rectangular frame-shaped hanging frame 1. One end of the mounting frame 13 along its own length direction is hinged to the frame 12 through a hinge, and the other end of the mounting frame 13 along its own length direction is provided with two bolts. When the mounting frame 13 blocks the opening on the upper side of the frame 12, the mounting frame 13 is fixed to the frame 12 through the bolts.
[0037] The limiting frame 2 and the frame 12 enclose the above-mentioned receiving groove 121, and the limiting frame 2 is movable relative to the frame 12 in the up-down direction, and the limiting frame 2 can be taken out through the opening on the upper side of the frame 12 by moving upward. A plurality of pipes 200 are placed in the receiving groove 121, and the limiting frame 2 is moved toward the direction close to the pipes 200, and then the limiting frame 2 is stopped by the stop assembly 3, so that the limiting frame 2 can be pressed against the pipes 200, and then the plurality of pipes 200 and the hanging frame 1 are relatively stable, thereby improving the stability and safety of the pipes 200 during the hanging process.
[0038] In some embodiments, Figure 3 As shown, the frame 12 has a slide groove 122 , and the limiting frame 2 can slidably cooperate with the slide groove 122 .
[0039] The limiting frame 2 is slidably fitted in the slide groove 122 , which can improve the sliding stability of the limiting frame 2 relative to the hanging frame 1 , and at the same time improve the relative stability of the limiting frame 2 and the pipeline 200 during the hanging process of the pipeline 200 .
[0040] Alternatively, if Figure 3 As shown, the slide grooves 122 are arranged on the two vertical side walls of the frame 12 , and the limiting frame 2 is in the shape of an elongated strip, and the two ends of the limiting frame 2 are respectively slidably fitted in the two slide grooves 122 .
[0041] Thereby, the relative stability between the limiting frame 2 and the pipeline 200 during the hoisting process can be further improved.
[0042] Optionally, the upper end of the slide slot 122 is open.
[0043] Thus, the limiting frame 2 can be slid upward and removed from the hanging frame 1 .
[0044] In some embodiments, the abutment assembly 3 includes an abutment member 31 for abutting the limiting frame 2 , and the abutment member 31 is movably connected to the mounting frame 13 .
[0045] By setting the stop member 31 and moving the stop member 31 relative to the mounting frame 13, the stop member 31 can stop the limit frame 2, and then the position of multiple pipes 200 is limited by the limit frame 2, thereby improving the stability of the pipes 200 during the lifting process and preventing the pipes 200 from slipping during the lifting process.
[0046] Optionally, the number of the stop components 3 is two, and the two stop components 3 are arranged at intervals along the length direction of the limiting frame 2 .
[0047] The two stop members 31 can apply a more uniform pressure to the limiting member, thereby achieving a better limiting effect on the multiple pipes 200 .
[0048] In some embodiments, the stop assembly 3 further includes a screw rod 32 , the screw rod 32 is passed through the mounting frame 13 and threadedly engaged with the mounting frame 13 , and the stop member 31 is connected to the screw rod 32 .
[0049] The movement of the stop member 31 can be controlled by rotating the screw rod 32, which is relatively easy to operate and has a low production cost.
[0050] As an example, Figure 2 As shown, the screw rod 32 extends vertically, and the mounting frame 13 has a threaded hole extending therethrough, and the screw rod 32 is threadedly engaged in the threaded hole; the stop member 31 is in the shape of a circular plate and is fixed to the lower end of the screw rod 32, and the diameter of the stop member 31 is larger than the outer diameter of the screw rod 32, so that the contact area between the stop member 31 and the limit frame 2 is larger, so that the force on the limit frame 2 is more uniform.
[0051] In some embodiments, the stop assembly 3 further includes an elastic member 33 , the stop member 31 and the hanging frame 1 are both connected to the elastic member 33 , and the elastic member 33 is used to apply an elastic force along the axial direction of the screw rod 32 to the stop member 31 .
[0052] The elastic member 33 applies elastic force to the stop member 31, and then applies an axial force to the screw rod 32, so that the threads of the screw rod 32 and the threads of the threaded hole are squeezed against each other, thereby making the connection between the screw rod 32 and the mounting frame 13 more stable, preventing the connection between the screw rod 32 and the mounting frame 13 from loosening during the lifting of the pipeline 200.
[0053] Optionally, the elastic member 33 is a spring, which is sleeved on the screw rod 32 , with one end abutting against the mounting frame 13 and the other end abutting against the abutting member 31 .
[0054] Thus, the spring can exert an elastic force on the stop member 31 toward the receiving groove 121 , thereby preventing the screw rod 32 and the mounting bracket 13 from loosening.
[0055] In some embodiments, a force applying member is detachably connected to the screw rod 32 .
[0056] By providing the force-applying member, it is more convenient for construction workers to screw the screw 32, thereby improving the convenience of operation. At the same time, during the hoisting process of the pipeline 200, the force-applying member can be removed to avoid collision between the force-applying member and other objects during the hoisting process of the pipeline 200, thereby improving the safety of the hoisting of the pipeline 200.
[0057] Specifically, the end of the screw rod 32 away from the stop member 31 has a force-applying hole, which is hexagonal, quadrilateral or cross-shaped; the force-applying member is a handwheel or a knob, and has a protrusion on the force-applying member that matches the shape of the force-applying hole. The protrusion of the force-applying member is inserted into the force-applying hole, and the rotation of the screw rod 32 can be controlled by the force-applying member.
[0058] In some embodiments, Figure 2 and Figure 3 As shown, the frame 12 includes a frame body 123 and a buffer layer 124 . The buffer layer 124 is disposed on the inner side of the frame body 123 , and the buffer layer 124 forms a bottom groove wall and a side groove wall of the accommodating groove 121 .
[0059] By providing the buffer layer 124, when multiple pipes 200 are placed in the receiving groove 121, the pipes 200 are pressed against the buffer layer 124, and the buffer layer 124 can be deformed and exert pressure on the pipes 200, so that adjacent pipes 200 are squeezed against each other, increasing the friction between adjacent pipes 200, thereby improving the stability of the multiple pipes 200 in the receiving groove 121 and reducing the probability of the pipes 200 slipping during the lifting process.
[0060] Optionally, the buffer layer 124 is made of rubber material, and the buffer layer 124 is bonded to the frame 123 .
[0061] In some embodiments, at least one of the bottom groove wall and the side groove wall of the receiving groove 121 has a plurality of limiting grooves 1241 , and the plurality of limiting grooves 1241 are arranged at intervals along the circumference of the receiving groove 121 .
[0062] By providing a plurality of limiting grooves 1241 , the plurality of limiting grooves 1241 can limit the plurality of pipes 200 at the edge positions, thereby further improving the stability of the plurality of pipes 200 during the hoisting process.
[0063] As an example, Figure 2 and Figure 3 As shown, the accommodating groove 121 has a bottom groove wall, a top groove wall and two side groove walls, and a plurality of limiting grooves 1241 are provided on the bottom groove wall, the top groove wall and the two side groove walls. The plurality of limiting grooves 1241 are evenly arranged along the circumference of the accommodating groove 121, and the spacing between two adjacent limiting grooves 1241 matches the pipe diameter of the pipe 200 to be hoisted, so that when two adjacent pipes 200 are fitted together, the two adjacent pipes 200 can fit the groove walls of the limiting grooves 1241 respectively.
[0064] Among them, the bottom groove wall and two side groove walls are formed on the buffer layer 124, and the top groove wall is formed on the limit frame 2; specifically, the limit frame 2 includes a limit portion 21 and a buffer portion 22 bonded to each other, the buffer portion 22 is made of rubber material, and the buffer portion 22 is arranged on the lower side of the limit portion 21, and the lower side of the buffer portion 22 forms the top groove wall of the accommodating groove 121.
[0065] In some embodiments, the limiting groove 1241 is an arc groove.
[0066] By setting the limiting groove 1241 as an arc groove, the contact surface between the pipeline 200 and the limiting groove 1241 is larger, thereby further improving the stability of the pipeline 200 in the accommodating groove 121.
[0067] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
