[0044] On both sides of each group of auxiliary moving components 17 along the length direction of the suspension beam 14, a group of support components 20 are arranged;

[0045] The support component 20 includes two first hydraulic telescopic cylinders 21. The first hydraulic telescopic cylinders 21 are arranged vertically. The two first hydraulic telescopic cylinders 21 are symmetrically arranged with respect to the center line of the suspension beam 14 in the width direction. The fixed end of the first hydraulic telescopic cylinder 21 is fixedly connected to the first connecting plate 13. The output end of the first hydraulic telescopic cylinder 21 is fixedly connected to a pressing block 22. One end of the pressing block 22 away from the first hydraulic telescopic cylinder 21 is located in the first groove 16. Anti-slip lines are provided on the side of the pressing block 22 close to the first connecting plate 13 to increase the pressing effect of the pressing block 22 on the suspension beam 14.

[0046] As Figure 1 、 Figure 3 , connection rings one 23 are fixedly connected to both ends of the suspension beam 14 along the length direction. The second support plate 24 is fixedly connected between the four third connecting columns 5. Wire rope winding devices one 25 are fixedly connected to both sides of the second support plate 24 along the length direction of the suspension beam 14;

[0047] Connection rings two 26 are fixedly connected to both sides of the inner wall of the two first grooves 16 along the length direction. Two third support plates 27 are arranged on the side of the first support plate 8 away from the second support plate 24;

[0048] One side of the third support plate 27 in the width direction is fixedly connected to the support column 2. Below the side of the third support plate 27 away from the support column 2 in the width direction, a fourth connecting column 28 is fixedly connected. One side of the fourth connecting column 28 away from the third support plate 27 is fixedly connected to the first connecting column 3;

[0049] Wire rope winding devices two 29 are fixedly connected to both sides of the two third support plates 27 along the length direction of the suspension beam 14. The wire rope winding devices two 29 on the same side of the two third support plates 27 are symmetrically arranged with respect to the center line of the suspension beam 14 in the width direction;

[0050] Both the first wire rope winding device 25 and the second wire rope winding device 29 are wire rope winders, and the wire rope winder is an existing conventional technology;

[0051] One end of the wire rope on the first wire rope winding device 25 is fixedly connected to the first connecting ring 23, and the suspension beam 14 is lifted by the first wire rope winding device 25;

[0052] One end of the wire rope on the second wire rope winding device 29 is fixedly connected to the second connecting ring 26, and the turning angle of the suspension beam 14 is controlled by controlling the winding length of the wire rope of the second wire rope winding device 29;

[0053] An angular displacement sensor (not shown in the figure) is fixedly connected to the suspension beam 14, and the turning angle of the suspension beam 14 relative to the support frame 1 is detected by the angular displacement sensor.

[0054] As Figure 6 , two first limiting blocks 30 are fixedly connected to the outer circumferential surface of the turntable 10. The two first limiting blocks 30 are symmetrically arranged with respect to the center line of the suspension beam 14 in the width direction. A first limiting groove 31 is formed on the circumferential side of the ring 9. One end of the first limiting block 30 away from the turntable 10 passes through the first limiting groove 31 and is slidably connected to the first limiting groove 31. A cylinder 32 is fixedly connected to the side of the first limiting block 30 away from the turntable 10;

[0055] The rotation angle of the turntable 10 is limited by the first limiting block 30 and the first limiting groove 31. The rotation range of the turntable 10 is controlled by controlling the arc length of the first limiting groove 31. The arc length of the first limiting groove 31 is positively correlated with the rotation range. In this embodiment, the maximum angle that the turntable 10 can rotate is 30° due to the arc length of the first limiting groove 31.

[0056] A moving block 33 is arranged corresponding to the cylinder 32 on the lower side of the first support plate 8. A sliding groove 34 is formed on the side of the moving block 33 close to the first support plate 8. The cross-sectional shape of the sliding groove 34 is a dovetail shape. A sliding rail 35 is fixedly connected to the lower side of the first support plate 8. The sliding rail 35 cooperates with the sliding groove 34 to enable the moving block 33 to slide along the sliding rail 35;

[0057] A second groove 36 is formed on the side of the moving block 33 close to the turntable 10. The cylinder 32 is located in the second groove 36, and the outer circumferential wall of the cylinder 32 is in direct contact with the inner wall of the second groove 36.

[0058] At both ends of the slide rail 35 in the length direction, there are two hydraulic telescopic cylinders 37. The second hydraulic telescopic cylinder 37 is horizontally arranged. The fixed end of the second hydraulic telescopic cylinder 37 is fixedly connected to the first support plate 8. The output end of the second hydraulic telescopic cylinder 37 is fixedly connected with a top block 38. The top block 38 is located directly below the slide rail 35. On one side of the top block 38 close to the moving block 33, there is an embedded contact sensor (not shown in the figure). The contact sensor is used to detect whether the top block 38 is in direct contact with the moving block 33.

[0059] A plurality of lifting rings (not shown in the figure) are fixedly connected to the support columns 2, the first connecting column 3, the second connecting column 4, the third connecting column 5, the fourth connecting column 28, the first support plate 8, the second support plate 24, and the third support plate 27, which is convenient for hoisting and transportation during disassembly and assembly.

[0060] In this embodiment, the pressure relief valve of the voltage stabilizer is lifted by the remote control electric hoist 15. At this time, the output end of the first hydraulic telescopic cylinder 21 is in the retracted state. The pressing block 22 jacks up the suspension beam 14 and cooperates with the first connecting plate 13 to tightly lock the suspension beam 14 to prevent the suspension beam 14 from shaking.

[0061] At the same time, the output end of the second hydraulic telescopic cylinder 37 is in the extended state. The top block 38 is in direct contact with the moving block 33, restricting the movement of the moving block 33. Subsequently, the first limiting block 30 cannot move, and the turntable 10 cannot rotate, thereby preventing the suspension beam 14 from rotating during the suspension process.

[0062] When it is necessary to turn the suspension beam 14, control the output end of the second hydraulic telescopic cylinder 37 to retract. By controlling the winding and unwinding lengths of the steel wires of the four wire rope winding devices 29 respectively and cooperating with the angular displacement sensor, the turning angle of the suspension beam 14 can be accurately adjusted. At the same time, the turntable 10 rotates, and the first limiting block 30 and the cylinder 32 rotate with the turntable 10. The cylinder 32 drives the moving block 33 to slide along the slide rail 35.

[0063] After the turning angle of the suspension beam 14 is adjusted, control the output end of the second hydraulic telescopic cylinder 37 to extend. Control the extension amounts of the two second hydraulic telescopic cylinders 37 on both sides of the moving block 33 through the contact sensor, so that the output end of the second hydraulic telescopic cylinder 37 stops extending after the top block 38 contacts the moving block 33 until the top blocks 38 of the two second hydraulic telescopic cylinders 37 on both sides of the moving block 33 are in contact with the moving block 33, thereby completing the fixation of the turntable 10 and preventing the turntable 10 from rotating during the turning process of the suspension beam 14.

[0064] When it is necessary to retract the suspension beam 14, the output end of the first hydraulic telescopic cylinder 21 is controlled to extend, so that the pressing block 22 descends and does not press the suspension beam 14. The suspension beam 14 contacts the pulley 18, and the rewinding and unwinding lengths of the steel wire are controlled by the first wire rope rewinding device 25, so that the suspension beam 14 moves along the length direction and is retracted.

[0065] Embodiment 2: The following structure is added on the basis of Embodiment 1:

[0066] A plurality of connecting rings 23 are provided, and the first wire rope rewinding device 25 can pull a plurality of steel wires.

[0067] A pressure sensor (not shown in the figure) is embedded on the side of the pressing block 22 close to the suspension beam 14 on the support assembly 20 provided at both ends of the suspension beam 14 along the length direction;

[0068] When the suspension beam 14 extends to one side along the length direction for hoisting, the pressure value acting on the support assembly 20 with the connecting plate 13 as the fulcrum after the suspension beam 14 hoists the pressure regulator safety valve is detected by the pressure sensor on a group of support assemblies 20 close to the extending direction of the suspension beam 14;

[0069] The pressure sensor is signal-connected to a processor (not shown in the figure), and multiple levels of pressure warning values are preset through the processor.

[0070] In this embodiment, an example is used to set the first-level pressure warning value through the processor, denoted as Y1; the second-level pressure warning value, denoted as Y2, and the third-level pressure warning value, denoted as Y3, where Y3 > Y2 > Y1;

[0071] The real-time pressure value received by the processor from the pressure sensor is denoted as Y0;

[0072] When Y0 ≤ Y1, it indicates that when the first wire rope rewinding device 25 pulls and hoists the suspension beam 14 through a single steel wire, the pressure generated by the suspension beam 14 on the corresponding support assembly 20 after hoisting the pressure regulator safety valve is within the safe range, and the hoisting work can be carried out safely;

[0073] When Y2 ≥ Y0 > Y1, it indicates that when the first wire rope rewinding device 25 pulls and hoists the suspension beam 14 through a single steel wire, the pressure generated by the suspension beam 14 on the corresponding support assembly 20 after hoisting the pressure regulator safety valve exceeds the safe range. The hoisting work is stopped, and at the same time, an additional steel wire for pulling and hoisting the suspension beam is added through the first wire rope rewinding device 25 to increase the tensile strength of the suspension beam 14 and reduce the pressure of the suspension beam 14 on the support assembly 20;

[0074] When Y3≥Y0>Y2, it indicates that when the wire rope winding device 1-25 hoists the suspension beam 14 with double wires, the pressure generated by the suspension beam 14 on the corresponding support assembly 20 after hoisting the voltage regulator safety valve exceeds the safety range. The hoisting work is stopped, and an additional wire for hoisting the suspension beam 14 is added through the wire rope winding device 1-25 to increase the tensile strength of the suspension beam 14 and reduce the pressure of the suspension beam 14 on the support assembly 20.

[0075] And so on. When Y0>Y3, the number of wires for hoisting the suspension beam 14 can be continuously increased correspondingly through the wire rope winding device 1-25.

[0076] According to the above example, based on the real-time pressure value Y0 detected by the pressure sensor, the number of wires for hoisting the suspension beam 14 is increased correspondingly through the wire rope winding device 1-25 to increase the tensile strength of the suspension beam 14, thereby reducing the pressure of the suspension beam 14 on the support assembly 20 and preventing the support assembly 20 from being damaged due to overpressure and causing safety accidents.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
