DETAILED DESCRIPTION

[0023] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0024] A hanging beam with a retractable cable, such as Figure 1-4 As shown, it includes an anti-sway device 1, whose upper end forms a suspension end 2 connected to the lifting equipment, and the lower end forms a connection part 3 between the beam body 6, which suppresses the swing of the suspended objects on the lower side around the horizontal axis and the vertical axis in the horizontal direction; in this embodiment, the anti-sway device 1 is connected to the retrieval device at the top, and connected to the beam body 6 at the bottom. In order to solve the problem of the shaking of the submersible, compared with the method of only using one-point suspension in the prior art, the part connected to the retrieval device is connected by a specially designed cross structure 12 in this embodiment. Specifically, the anti-sway device 1 includes two cross structures 12 aligned vertically in the upper and lower parts and four connecting rods 13. The cross structure 12 is in a cross-shaped vertical cross on the horizontal plane and includes a horizontal axis frame 14 and a vertical axis frame 15. The four ends of the two cross structures 12 are connected by connecting rods 13. As shown Figure 1 , 2 As shown, in this embodiment, mutually aligned cross structures 12 are arranged in the upper and lower directions, each cross structure 12 is horizontal, the transverse axis frames 14 of the upper and lower cross structures 12 are mutually aligned, and the longitudinal axis frames 15 are also mutually aligned. The cross structure 12 has four end points. During actual assembly, the corresponding end points of the upper and lower cross structures 12 are connected by a connecting rod 13. It can be understood that the connecting rod 13 here can be a hard rod. Since it is a hoisting operation, the connecting rod 13 can also be replaced by a soft steel cable; during actual use, since the upper cross structure 12 is composed of mutually staggered transverse axis frames 14 and longitudinal axis frames 15, the upper end surface of the upper cross structure 12 can be positioned using a retractable device, that is, the transverse axis frames 14 and longitudinal axis frames 15 are fixed, and then the lower cross structure 12 is also positioned, so as to achieve anti-sway fixation of the lower lifting equipment to prevent it from deflecting around the transverse axis direction 4 or the longitudinal axis direction 5. The positioning in the two axial directions can make the lifting equipment stable during the up and down lifting process.

[0025] like Figure 1 , 2 As shown, in this embodiment, H-shaped steel is used to process and manufacture the cross structure 12. It can be understood that the processing profile is not limited, and square tubes, C-shaped steel, L-shaped steel, etc. can also be used; the lower cross structure 12 is connected to the lower cross beam body 6 through the connecting part 3.

[0026] Specifically, the crossbeam body 6 is rotatably connected to the lower side of the anti-sway device 1. When in use, the setting of the anti-sway device 1 enhances the stability of the lower crossbeam body 6. In this embodiment, a rotatable connection is added, so that the direction of the submersible can be changed more easily during the lifting and lowering operation of the submersible, which is convenient for adjusting the posture of the submersible; specifically, a drive device mounting frame 16 is provided in the middle of the crossbeam body 6, and the top of the drive device mounting frame 16 forms a connecting end. The drive device mounting frame 16 includes triangular side plates 31, and the triangular side plates 31 are correspondingly arranged on both sides of the middle of the main beam 7, so that an installation space for the winch part 10 is formed between the two triangular side plates 31. In order to strengthen the overall strength, a support column 38 is provided between the two triangular side plates 31, and a connecting crossbeam 32 is provided between the tops of the two. The connecting portion 3 of the cross structure 12 on the lower side is rotatably connected with the connecting end, so that the crossbeam body 6 can be controlled to rotate in the horizontal direction relative to the anti-sway device 1; specifically, as Figure 2 As shown, the connection portion 3 of the lower cross structure 12 can be a connecting shaft 33 vertically arranged at the cross machining center position, and the connecting beam 32 is provided with an axial hole corresponding thereto, and the axial hole is sleeved on the connecting shaft 33 to realize the rotation connection. In actual use, in order to achieve the purpose of automatically controlling the rotation direction of the submersible, an active driving mechanism (not shown in the figure) can also be set at the connecting shaft 33, and the active driving mechanism is installed in the space formed between the two cross structures 12, and the connecting beam 32 is driven by a reduction motor and other structures to rotate in a controllable direction relative to the anti-sway device 1.

[0027] In this embodiment, the cross beam body 6 includes a main beam 7 and a secondary beam 8. The secondary beams 8 are arranged at both ends of the main beam 7, so that the cross beam body 6 forms four suspension points 9 at both ends; Figure 1 , 2 As shown, the main beam 7 is an I-shaped beam, and the two ends of the main beam 7 are vertically provided with auxiliary beams 8, and the main beam 7 is connected to the middle of the auxiliary beam 8, so that the cross beam body 6 forms an I-shaped structure, and the suspension points 9 are formed at the two ends of the auxiliary beam 8. The main beam 7 can be arranged along the length direction of the submersible, so that the front and rear ends of the submersible can be hoisted, and the auxiliary beams 8 arranged along the longitudinal axis direction 5 can increase the width of the suspension points 9, forming hoisting at four positions of the submersible, so that the submersible can remain stable during the lifting process; when in use, the four suspension points 9 simultaneously perform the deployment and recovery operations on the submersible equipment, and the submersible can be controlled to be lifted and lowered smoothly.

[0028] The winch unit 10 in the middle of the crossbeam body 6 has a cable structure 11 with four sets of synchronous cable retracting and releasing controls; the four sets of cables lead to four suspension points 9 respectively and form a four-point suspension type hoisting on the target equipment. Specifically, the winch unit 10 is arranged in the installation space in the drive equipment installation frame 16, and the two sides of the drive equipment installation frame 16 are provided with side openings 17 facing the sub-beam 8 and for the cable arrangement, such as Figure 2 As shown, the side opening 17 is formed by the interval between two triangular side plates 31. The winch part 10 includes four groups of cable drums 18, and four steel cables 19 are respectively wound on the four groups of cable drums 18. When in use, the four cable drums 18 respectively control the corresponding steel cables 19 to be wound and unwound, thereby controlling the winding and releasing of the steel cables 19 at the corresponding suspension points 9. It can be understood that when the submersible is deployed, the cable should be released or wound up synchronously, thereby controlling the smooth lifting and lowering of the submersible. Specifically, in this embodiment, the four steel cables 19 are grouped in two, and the two groups of steel cables 19 lead to the two groups of subbeams 8 respectively, and each suspension point 9 of the subbeam 8 is arranged with a steel cable 19. When controlling the cable drum 18, the rotation of the drum is controlled at the same time to achieve synchronous winding and releasing of the steel cables 19.

[0029] Specifically, Figure 4 As shown, the four groups of cable drums 18 of the winch unit 10 are grouped into two drum groups 20, and the two cable drums 18 on the drum group 20 are fixedly connected end to end, so that the two cable drums 18 on the same drum group 20 are synchronously retracted and released; further, the two drum groups 20 are also controlled to rotate synchronously to realize the retraction and release of the steel cable 19. Specifically, as shown in FIG. Figure 4 As shown, the drum shafts 21 of the two drum groups 20 are arranged parallel to each other, the drum group 20 is rotatably sleeved on the drum shaft, and the two ends of the drum shaft are installed in the shaft mounting holes 34 on the triangular side plates 31, so that the two drum shafts 21 are positioned by the driving device mounting frame 16, and a driven gear 24 is also provided on the drum shaft 21, and the rotation of the corresponding drum group 20 can be controlled by the rotation of the driven gear 24. The drum shaft 21 is rotatably arranged on the driving device mounting frame 16 and driven by the driven gear 24. Further, the winch part 10 also includes a driving shaft 22, which is the output shaft of a reduction gear box 35. The reduction gear box 35 is fixed to the inner bottom of the driving device mounting frame 16 through a positioning bracket 36. A driving motor 37 is arranged at the input end of the reduction gear box 35, so that the driving shaft 22 is driven by the driving motor 37, and the reduction gear box 35 reduces the output speed and increases the torque, as shown in FIG. Figure 3 , 4As shown, a driving gear 23 is provided on the driving shaft 22, and driven gears 24 are provided on the two drum shafts 21, respectively. The driving gear 23 is meshed and connected with the two driven gears 24 at the same time; the synchronous rotation of the two driven gears 24 can be synchronously controlled by the driving gear 23, thereby realizing synchronous control of the four cable drums 18; Figure 3 As shown, the driving gear 23 is located between the two driven gears 24, and the two sides of the driving gear 23 are respectively meshed with the driven gears 24 on both sides; thereby, the two driven gears 24 rotate in the same direction. When the driving gear 23 rotates clockwise, as shown in FIG. Figure 5 As shown by the arrow in the middle, the two driven gears 24 rotate counterclockwise. Therefore, in order to achieve synchronous cable retraction and release, the steel cables 19 on the two reel groups 20 are wound in different ways, that is, Figure 5 As shown, the right drum group 20 has the lower side outlet, and the left drum group has the upper side outlet. It is understandable that in order to evenly arrange the steel cables 19 on the cable drum 18, the person skilled in the art can also set a corresponding cable arrangement device to ensure that the retracted and released lengths of each group of steel cables 19 are the same and the winding is regular.

[0030] Furthermore, the cross beam body 6 is also provided with a guide wheel device 25, and the guide wheel device 25 includes a first guide wheel 26, a second guide wheel 28, and a clamping roller frame 30. The two ends of the main beam 7 are respectively provided with a clamping roller frame 30 and a first guide wheel 26. The clamping roller frame 30 includes two clamping rollers arranged in parallel, and there is a spacing between the two clamping rollers for the steel cable 19 to pass through. The two ends of the clamping rollers are rotatably connected to the vertical plates on both sides, and the lower ends of the vertical plates are fixed on the main beam 7. The clamping roller frame 30 is used to guide the steel cable 19 into the first guide wheel 26. Specifically, the first guide wheel 26 is water-tight. It is arranged horizontally at the end of the main beam 7 and is located on the outside of the clamping roller frame 30. Two first guide wheels 26 are symmetrically arranged on the outside of one clamping roller frame 30. The two first guide wheels 26 guide one steel cable 19 respectively and guide the corresponding steel cable 19 to the second guide wheel 28 at the end of the sub-beam 8. The ends of the sub-beam 8 are respectively rotated to set the second guide wheels 28, and the second guide wheels 28 are arranged in a vertical direction. The steel cables 19 arranged in groups are guided by the clamping roller frame 30 and the first guide wheel 26, and are respectively turned to the second guide wheels 28 at both ends, and then turned to be arranged downward. Thus, the four groups of steel cables 19 are guided by the two guide wheels and enter the limit cylinder 29 arranged at the end of the sub-beam 8; the limit cylinder 29 can limit the position of the corresponding steel cable 19 in the horizontal direction and correspond to the position of the suspension point 9 arranged on the submersible.

[0031] The cables placed at the four corners of the cross beam body 6 are connected to the submersible. By controlling the forward and reverse rotation of the winch part 10, the submersible can be raised and lowered, and the four hanging points are synchronously stable, and the whole hanging beam is not easy to shake.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
