[0006] When the regulating mechanism is subjected to pressure from the iron pipe, the limiting mechanism is energized and magnetized to be magnetically adsorbed to the iron pipe. When the regulating mechanism is free of pressure, the electromagnetic force of the limiting mechanism is cut off and disappears.

[0025] like Figure 1 and Figure 2 As shown, Figure 1 It is a front view of the overall structure of the present invention; Figure 2 It is a front view of the supporting mechanism in the present invention.

[0026] The auxiliary installation hanger for iron pipe fittings comprises a rotating mechanism 1 for driving the iron pipe fittings to rotate and move, a supporting mechanism 2 is arranged above the rotating mechanism 1, a winding mechanism 3 for adjusting the height of the iron pipe fittings in the vertical direction is arranged on the supporting mechanism 2, an adjusting mechanism 4 for responding to the pressure of the iron pipe fittings and generating a signal change is arranged on the movable end of the winding mechanism 3, and a plurality of limit mechanisms are arranged at the bottom of the adjusting mechanism 4;

[0027] When the regulating mechanism 4 is subjected to pressure from the iron pipe, the limiting mechanism 5 is energized and magnetized to be magnetically adsorbed to the iron pipe. When the regulating mechanism 4 is free of pressure, the electromagnetic force of the limiting mechanism 5 is cut off and disappears.

[0028] Specifically, at least two groups of limiting mechanisms 5 are provided, and the two groups of limiting mechanisms 5 can be respectively plugged into the two ends of the iron pipe fittings. The movable end of the winding mechanism 3 can drive the adjusting mechanism 4 to move in the vertical direction. When the winding mechanism 3 drives the adjusting mechanism 4 to move upward, the adjusting mechanism 4 drives the iron pipe fittings to move through the limiting mechanism 5. In the process of the iron pipe fittings being separated from the ground, the adjusting mechanism 4 will be subjected to the pressure of the iron pipe fittings, thereby causing a signal change, so that the limiting mechanism 5 is energized at the specified position, so that it is magnetized and can generate magnetic force with the iron pipe fittings, so that the limiting mechanism 5 can be fixed, avoiding the safety hazard caused by the towing hook, and improving the safety of the movement of the iron pipe fittings. In addition, the rotating mechanism 1 drives the supporting mechanism 2 to rotate and move without manual rotation, and the iron pipe fittings can be ductile iron pipe fittings.

[0029] Further, refer to Figure 1 The rotating mechanism 1 includes a base 11, a motor 12 and a rotating shaft. The top of the base 11 is rotatably connected to the rotating shaft, and the top of the rotating shaft is fixedly connected to the bottom of the supporting mechanism 2. A motor 12 is arranged on one side of the top of the base 11, and a transmission belt is sleeved between the output shaft of the motor 12 and the rotating shaft.

[0030] Specifically, the base 11 can be fixed in a specified position by bolts. In order to reduce the labor intensity of the staff, the motor 12 can drive the rotating shaft to rotate through the transmission belt, and the rotating shaft drives the supporting mechanism 2 to rotate in a circle, so that the supporting mechanism 2 cooperates with the winding mechanism 3, the adjusting mechanism 4 and the limiting mechanism 5 to move the iron pipe fitting to the specified position.

[0031] Furthermore, the support mechanism 2 includes a fixed plate 21, an inclined rod 22 and a pulley. The fixed plate 21 is fixedly connected to the top of the rotating shaft. The inclined rod 22 is provided at one end of the fixed plate 21. The end of the inclined rod 22 away from the fixed plate 21 is rotatably connected to the pulley.

[0032] Specifically, refer to Figure 1 and Figure 2The fixed plate 21 and the diagonal rod 22 are an integrally formed structure, which increases the strength of the connection between the fixed plate 21 and the diagonal rod 22. The pulley can change the direction of the hoisting rope 32 and avoid friction between the hoisting rope and the diagonal rod 22, thereby extending the service life of the hoisting rope 32.

[0033] Furthermore, the winding mechanism 3 includes a winch 31 and a winch rope 32. The winch 31 is fixedly connected to the fixed plate 21. The winch 31 is provided with a winch rope 32. The movable end of the winch rope 32 is fixedly connected to the adjusting mechanism 4 after passing through a pulley that changes direction along the direction of the inclined rod 22.

[0034] Specifically, refer to Figure 1 The winch 31 can reel in or release the hoisting rope 32. The hoisting rope 32 changes direction through the pulley, and can move the adjusting mechanism 4 in the vertical direction. The adjusting mechanism 4 drives the limiting mechanism 5 to move in the vertical direction, thereby adjusting the distance between the iron pipe and the ground through the limiting mechanism 5, which is convenient for transportation and installation.

[0035] Furthermore, the adjusting mechanism 4 includes an outer sleeve 41, a spring 42, a guide sleeve 43, a sensing component 44, a PLC control module 45 and a wireless transmission module 46. The movable end of the winding mechanism 3 is fixedly connected with an "I"-shaped guide sleeve 43. The outer surface of the guide sleeve 43 is movably sleeved with the outer sleeve 41. The spring 42 is wound on the surface of the guide sleeve 43 and located inside the outer sleeve 41. The outer sleeve 41 is provided with a sensing component 44. The guide sleeve 43 is provided with a PLC control module 45. The PLC control module 45 is signal-connected to the wireless transmission module 46.

[0036] Specifically, refer to Figure 1 and Figure 3When the two sets of limiting mechanisms 5 are respectively plugged into the two ends of the iron pipe, the winch 31 reels the hoisting rope 32. When the iron pipe is gradually lifted, the guide cylinder 43 will be pulled, and the outer sleeve 41 will move downward under the pulling force of the limiting mechanism 5 to squeeze the spring 42, so that the gap between the bottom of the inner wall of the outer sleeve 41 and the bottom of the guide cylinder 43 becomes larger and larger, thereby causing the signal of the induction component 44 to change. The PLC control module 45 receives the signal and then transmits the instruction to the limiting mechanism 5 through the wireless transmission module 46, so that the specified position of the limiting mechanism 5 is magnetized, which can generate magnetic force with the iron pipe, so that the limiting mechanism 5 and the iron pipe can be limited to each other, avoiding the safety hazard caused by the towing hook, and improving safety. The safety issue of the movement of iron pipe fittings is improved. When the iron pipe fittings are placed in the specified position, the limiting mechanism 5 does not generate pressure on the outer sleeve 41. Under the action of the restorative elastic force of the spring 42, the outer sleeve 41 is pushed to return to the initial position, so that the signal of the sensing component 44 is restored to the initial state. At this time, the instruction of the PLC control module 45 is transmitted to the limiting mechanism 5 again through the wireless transmission module 46, so that the power is cut off at the specified position of the limiting mechanism 5, so that it is demagnetized, which is convenient for the staff to separate the limiting mechanism 5 from the iron pipe fittings. Among them, a sliding groove is provided on the surface of the guide cylinder 43, which can limit and fix the moving position of the outer sleeve 41 to avoid excessive squeezing of the spring 42, which causes the spring 42 to undergo non-elastic deformation.

[0037] Furthermore, the sensing component 44 includes a proximity switch 441 and a sensing head 442. The proximity switch 441 is arranged at the bottom of the guide cylinder 43, and the sensing head 442 used in conjunction with the proximity switch 441 is arranged at the bottom of the inner wall of the outer sleeve 41. The proximity switch 441 is connected to the PLC control module 45 by signal.

[0038] Specifically, refer to Figure 3 A proximity switch 441 is embedded in a groove at the bottom of the guide cylinder 43, and a sensing head 442 is also embedded in a groove at the bottom of the inner wall of the outer sleeve 41. When the proximity switch 441 and the sensing head 442 are close to each other, a signal will be generated. When the proximity switch 441 and the sensing head 442 are far away from each other, the signal will disappear. The PLC control module 45 can receive the signal change and make instructions. Among them, the proximity switch 441 can be an eddy current proximity switch, and the sensing head 442 is a conductor. When a conductive object approaches this switch that can generate an electromagnetic field, eddy currents are generated inside the conductive object. This eddy current reacts to this switch, causing the internal circuit parameters of the switch to change, thereby identifying whether a conductive object is approaching. In order to cooperate with its normal use, the surface or inner wall of the outer sleeve 41 and the guide cylinder 43 are coated with insulating materials.

[0039] Furthermore, buffer seats are provided on both sides of the bottom of the inner wall of the outer sleeve 41 to reduce the collision force between the outer sleeve 41 and the guide sleeve 43 .

[0040] Specifically, refer to Figure 3 The buffer seat is used to reduce the collision force between the outer sleeve 41 and the guide sleeve 43 on the one hand, and to avoid damage caused by direct collision between the proximity switch 441 and the sensor head 442 on the other hand. The buffer seat can be a rubber pad fixedly connected to both sides of the bottom of the inner wall of the outer sleeve.

[0041] Furthermore, the limiting mechanism includes a connecting rope 51, a limiting buckle 52 and an electromagnet 53. A plurality of connecting ropes 51 are arranged at the bottom of the adjusting mechanism 4. A "C"-shaped limiting buckle 52 is arranged at the bottom of the connecting rope 51. An electromagnet 53 is arranged at the bottom of the inner wall of the limiting buckle 52 through a groove. The electromagnet 53 is coupled to the wireless transmission module 46 for controlling the electromagnet 53 to be energized.

[0042] Specifically, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , two sets of limit buckles are respectively inserted into the two ends of the pipe fittings. When the PLC control module 45 sends a command to the wireless transmission module 46, the electromagnet 53 is energized and magnetized, so that magnetic attraction is generated between the electromagnet 53 and the iron pipe fitting, and the limit buckle 52 and the iron pipe fitting are limited and fixed to each other, avoiding the problem of the limit buckle 52 being unhooked.

[0043] Furthermore, a limiting seat 6 is provided on one side where the inclined rod 22 and the limiting mechanism 5 meet, and the limiting seat 6 is plugged into the limiting buckle 52 .

[0044] Specifically, refer to Figure 1 and Figure 2The cross section of the limit seat 6 is an inverted "L"-shaped structure and is made of metal iron. When the sling is not needed, the limit buckle 52 is plugged into the limit seat 6, and then the winch 31 is started, so that the winch rope 32 drives the adjustment mechanism 4 to move upward, which will give the guide cylinder 43 an upward pressure. Since the limit buckle 52 is plugged into the limit seat 6, under the blocking effect of the limit seat 6, the gap between the bottom of the guide cylinder 43 and the bottom of the inner wall of the outer sleeve 41 becomes larger and larger, thereby causing the signal of the induction component 44 to change. At this time, the command of the PLC control module 45 can be transmitted to the electromagnet 53 through the wireless transmission module 46. The electromagnet 53 is energized, so that the electromagnet 53 is magnetized and can interact with the electromagnet 53. The limit seat 6 generates magnetic force, so that the limit buckle 52 can be fixed to avoid the limit buckle 52 shaking under the action of the connecting rope 51 when not in use during the movement of the sling, thereby causing a safety hazard. When the limit buckle 52 needs to be separated from the limit seat 6, the winch rope 32 can drive the adjustment mechanism 4 to move downward. Under the action of the spring 42, the gap between the bottom of the guide cylinder 43 and the bottom of the inner wall of the outer sleeve 41 becomes smaller and smaller until the signal of the sensing component 44 returns to the initial state. The command of the PLC control module 45 can be transmitted to the electromagnet 53 through the wireless transmission module 46. The electromagnet 53 is powered off and demagnetized, and the limit buckle 52 can be easily removed from the limit seat 6.
