[0024] like Figure 6Two first limit blocks 30 are fixedly connected to the outer circumferential surface of the turntable 10. The two first limit blocks 30 are symmetrically arranged along the center line of the suspension beam 14 in the width direction. A first limit groove 31 is opened on the circumferential side of the ring 9. One end of the first limit block 30 away from the turntable 10 passes through the first limit groove 31 and is slidably connected to the first limit groove 31.

The arc length of the first limit slot 31 is positively correlated with the rotation range.

[0025] A moving block 33 is provided on the lower side of the first support plate 8 corresponding to the cylinder 32. A slide groove 34 is provided on the side of the moving block 33 close to the first support plate 8. The cross-sectional shape of the slide groove 34 is dovetail-shaped. A slide rail 35 is fixedly connected to the lower side of the first support plate 8. The slide rail 35 cooperates with the slide groove 34 to enable the moving block 33 to slide along the slide rail 35.

The output ends of the hydraulic telescopic cylinders 37 are fixedly connected to a top block 38. The top block 38 is located directly below the slide rail 35. A contact sensor (not shown in the figure) is embedded on one side of the top block 38 close to the moving block 33. The contact sensor is used to detect whether the top block 38 is in direct contact with the moving block 33.

[0027] The support column 2, the first connecting column 3, the second connecting column 4, the third connecting column 5, the fourth connecting column 28, the first supporting plate 8, the second supporting plate 24 and the third supporting plate 27 are all fixedly connected with a plurality of lifting rings (not shown in the figure) to facilitate lifting and transportation during disassembly and assembly.

[0028] In this embodiment, the voltage regulator safety valve is lifted by a remote-controlled electric hoist 15. At this time, the output end of the hydraulic telescopic cylinder 21 is in a retracted state, the pressing block 22 lifts the suspension beam 14, and cooperates with the connecting plate 13 to press and lock the suspension beam 14 to prevent the suspension beam 14 from shaking; At the same time, the output end of the hydraulic telescopic cylinder 37 is in an extended state, and the top block 38 is in direct contact with the moving block 33, limiting the movement of the moving block 33, thereby preventing the first limit block 30 from moving, and the turntable 10 cannot rotate, thereby preventing the suspension beam 14 from rotating during the suspension process.

[0029] When the suspension beam 14 needs to be turned, the output end of the hydraulic telescopic cylinder 2 37 is controlled to retract, and the winding and unwinding lengths of the four wire rope winding devices 29 are controlled, and the angle displacement sensor is used to accurately adjust the turning angle of the suspension beam 14. At the same time, the turntable 10 rotates, and the first limit block 30 and the cylinder 32 rotate with the turntable 10, and the cylinder 32 drives the moving block 33 to slide along the slide rail 35; After the adjustment of the rotation angle of the suspension beam 14 is completed, the output end of the hydraulic telescopic cylinder 2 37 is controlled to extend, and the extension amount of the two hydraulic telescopic cylinders 2 37 on both sides of the moving block 33 is controlled by the contact sensor, so that after the top block 38 contacts the moving block 33, the output end of the hydraulic telescopic cylinder 2 37 stops extending further until the top blocks 38 of the two hydraulic telescopic cylinders 2 37 on both sides of the moving block 33 contact the moving block 33, thereby completing the fixation of the turntable 10 and preventing the turntable 10 from rotating during the rotation of the suspension beam 14.

[0030] When the suspension beam 14 needs to be retracted, the output end of the hydraulic telescopic cylinder 21 is controlled to extend, so that the pressure block 22 descends and does not press the suspension beam 14. The suspension beam 14 contacts the pulley 18, and the winding and unwinding length of the steel wire is controlled by the wire rope winding device 25, so that the suspension beam 14 moves along the length direction and completes the retraction.

[0031] Embodiment 2 adds the following structure on the basis of embodiment 1: There are multiple connecting rings 23, and the wire rope winding device 25 can pull multiple steel wires.

[0032] A pressure sensor (not shown in the figure) is embedded in the side of the pressing block 22 on the support assembly 20 at both ends of the suspension beam 14 along the length direction close to the suspension beam 14; When the suspension beam 14 is extended to one side along the length direction for hoisting, the pressure sensor on a group of support components 20 close to the extension direction of the suspension beam 14 detects the pressure value of the support component 20 with the connecting plate 13 as the fulcrum after the stabilizer safety valve hoisted by the suspension beam 14; The pressure sensor signal is connected to a processor (not shown in the figure), and multiple levels of pressure warning values ​​are preset by the processor.

[0033] In this embodiment, the processor exemplarily sets a first-level pressure warning value, which is recorded as Y1; a second-level pressure warning value, which is recorded as Y2; and a third-level pressure warning value, which is recorded as Y3, where Y3>Y2>Y1; The real-time pressure value of the pressure sensor received by the processor is recorded as Y0; When Y0≤Y1, it indicates that when the wire rope winding device 25 pulls the suspension beam 14 through a single wire, the pressure generated by the suspension beam 14 on the corresponding support assembly 20 after the stabilizer safety valve is hoisted is within the safe range, and the hoisting work can be carried out safely; When Y2≥Y0>Y1, it indicates that when the wire rope winding device 25 pulls the suspension beam 14 through a single steel wire, the pressure generated by the suspension beam 14 on the corresponding support assembly 20 after the voltage stabilizer safety valve is hoisted exceeds the safety range, and the hoisting work is stopped. At the same time, a steel wire is added to the suspension beam through the wire rope winding 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; When Y3≥Y0>Y2, it indicates that when the wire rope winding device 25 pulls the suspension beam 14 through two steel wires, the pressure generated by the suspension beam 14 on the corresponding support assembly 20 after the voltage stabilizer safety valve is hoisted exceeds the safety range, and the hoisting work is stopped. The wire rope winding device 25 is used to add a steel wire to pull the suspension beam 14, thereby increasing the tensile strength of the suspension beam 14 and reducing the pressure of the suspension beam 14 on the support assembly 20; By analogy, when Y0>Y3, the number of steel wires for pulling the suspension beam 14 can be increased correspondingly through the steel wire winding device 25; According to the above example, based on the real-time pressure value Y0 detected by the pressure sensor, the number of steel wires used to pull the suspension beam 14 is increased through the wire rope winding device 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 by overpressure and causing a safety accident.
