Description

Technical Field

[0001] The invention belongs to the field of ship engineering technology, and more specifically, relates to an emergency braking device for a rope of a fully rotating crane ship. Background Art

[0002] In recent years, the global large-scale offshore crane vessels have developed rapidly. According to the International Ship Network, by 2021, its international market value has reached 2.16 billion US dollars. As a special offshore equipment, the fully revolving crane vessel is widely used in the fields of oil, ports, bridges, salvage engineering, and large-scale offshore military equipment engineering. With the continuous improvement of international market demand, the requirements for the lifting capacity of ship-borne cranes are gradually increasing, and the large-scale trend of crane ship platforms equipped with cranes and their equipment is constantly emerging. The innovation of its related equipment and technology has become the key to the development of this type of offshore vessels.

[0003] In actual operation, when the fully revolving crane ships serving offshore operations are affected by unpredictable strong sea winds, the crane ropes will vibrate dangerously, and their workload will suddenly increase, causing abnormal displacement of the working ropes, destroying their normal working state; on the other hand, the cranes of fully revolving crane ships serving in ice environments are prone to safety problems such as rope overload slippage or sudden dangerous breakage when working in low temperature environments. Therefore, it is urgent for technicians to solve the above problems.

[0004] In the prior art, emergency braking of crane ropes often involves making changes to the winch or connecting the protection mechanism to the motor to achieve power failure. For example, the comparative document CN201810690848.X provides a crane weight limit protection mechanism, a crane and a truck crane, which controls the limit switch to switch the motor on and off to protect it through an elastic support component. However, this solution is only suitable for small equipment. The crane on the crane ship carries a heavy load, and the crane rope is long. It takes time for the force to be transmitted from the end of the rope to the motor, which cannot meet the needs in an emergency. For example, the comparative document CN201610035448.6 provides a rope clamp that uses a wedge-shaped clamp to brake in an emergency, but this solution can only be used for one rope. If it is to be applied to multiple ropes, multiple rope clamps need to be placed, which is not easy to manage uniformly. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to propose a fully revolving crane ship crane rope emergency brake device, which combines mechanical principles and damping related knowledge, and sets an emergency brake device with self-adjustable position on the rope of the fully revolving crane ship crane, so that all ropes can be managed uniformly with one device, and the rope braking function of the fully revolving crane ship crane in an emergency state can be effectively realized, so as to prevent sudden safety accidents and protect the work safety of crane operators.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The invention discloses a fully rotating crane ship crane rope emergency brake device, such as Fig.19As shown, it is matched with the ropes of the full-revolving crane ship. Because the conventional crane ship crane ropes are generally three, for the convenience of description, the three ropes are named two movable ropes 10 and one fixed rope 2.5 in this embodiment. If in other possible embodiments, there are more than three ropes, the number of fixed ropes remains unchanged, and only the number of movable ropes needs to be increased.

[0045] like Figure 1-Figure 4 As shown, the present invention includes an antifreeze housing 1, an emergency locking module, a limit module and an electric transmission module 5, and the emergency locking module, the limit module and the electric transmission module 5 are all fixed in the antifreeze housing 1. The emergency locking module is set as at least two groups, each group is arranged in parallel, including a plurality of rope transmission devices 4 and an emergency collapse cable device 3; the limit module is set as a group, parallel to the emergency locking module, including a plurality of limit blocks 2. The movable rope 10 and the fixed rope 2.5 are arranged in parallel and pass through the left and right sides of the entire device. The number of movable ropes 10 is the same as the number of groups of emergency locking modules, and the number of fixed ropes 2.5 is the same as the number of groups of limit modules. The two movable ropes 10 pass through one group of emergency locking modules respectively, and the fixed ropes 2.5 pass through the limit modules accordingly. In this embodiment, the limit modules are arranged below the two groups of emergency locking modules. In other possible embodiments, the limit modules can also be arranged above the emergency locking modules or between several groups of emergency locking modules.

[0046] like Figure 5 As shown, the antifreeze housing 1 is set as a rectangular parallelepiped, with solar panels 6 evenly embedded in the front and rear surfaces, a cross-winding interlayer 7 with a special cross-winding structure is attached to the inner layer, and batteries 8 are rigidly connected to the inner sides of the four corners. Three rope access holes are set on the left and right sides of the antifreeze housing 1 for the crane rope to enter and exit. Fig.15 As shown, the cross winding interlayer 7 is an electric heating device with two cross-wrapped metal heating elements arranged in a staggered manner, covering the entire antifreeze shell 1 to keep warm. When the full-revolving crane works in a low-temperature area, the solar panel 6 absorbs energy, and the cross winding interlayer 7 receives the electric energy generated from the solar panel 6, converts the electric energy into heat energy, and generates a certain amount of heat to protect the normal operation of the internal components of the device. In addition, the energy absorbed by the solar panel 6 is stored in the battery 8, which can also be used as a backup power supply in an emergency.

[0047] like Figure 6-7As shown, the telex module 5 is arranged symmetrically on the left and right, and includes several parallel transmission channels 2.10. The transmission channel 2.10 has a steel structure reinforced shell with an insulating interlayer, and the two ends of the interior are connected to the conductive connector 5.1, and the two ends of the exterior are connected to the small electrical box 5.3 by tightening the internal threads of the insulating bolts 5.2. Several groups of small electrical boxes 5.3 adjacent to each other are connected by welding through the transmission connection shaft 5.8 to balance the current of the entire circuit. The outer side of the small electrical box 5.3 is connected to a reinforced connection shaft 5.4, and the reinforced connection shaft 5.4 connects the signal box 5.5 to the small electrical box 5.3 by welding. The outer side of the signal box 5.5 is threadedly connected to the partition 5.10 by a structural fixing bolt 5.6, and the partition 5.10 is vertically welded in the antifreeze shell 1, which plays a role in vertical positioning inside the entire device structure. In addition, it also includes a structural connection shaft 5.7, which is welded to several groups of signal boxes 5.5 to play a role in longitudinal positioning inside the entire device structure.

[0048] The working principle of the electric transmission module 5 is as follows: the power of the storage battery 8 is supplied to the small electric box 5.3 through the power transmission connection shaft 5.8, and the small electric box 5.3 and the signal box 5.5 transmit the power and signal to the power transmission channel 2.10 through the conductive joint 5.1. A large number of cables are buried in the transmission channel 2.10 to transmit the current and signal to each module. Among them, the circuit in the small electric box 5.3 and the control circuit in the signal box 5.5 are conventional means in the art, and will not be repeated in the present invention.

[0049] In other possible embodiments, an energy storage device may also be provided in the small power box 5.3, and several small power boxes 5.3 may be connected to each other and used as an emergency power source when working in a dangerous state.

[0050] like Figure 2-4 As shown, the rope transmission device 4 is installed directly above the emergency cable collapse device 3. The rope transmission device 4 is fixed to the outside of the transmission channel 2.10 through the cooperation between the fixed base 4.2 and the fixed foundation 5.9. The emergency cable collapse device 3 is rigidly fixed to the top of the fixed foundation 5.9 by welding. The emergency cable collapse device 3 is not provided on the fixed foundation 5.9 of the outermost group of rope transmission devices 4 near the upper and lower edges of the antifreeze shell 1.

[0051] like Figure 16-18 As shown, the fixed foundation 5.9 is set in a T-shape, and the lower end of the vertical part is provided with a thread, which matches the vertical part of the fixed base 4.2. The vertical part of the fixed foundation 5.9 passes through the power transmission channel 2.10 and is threadedly connected to the fixed base 4.2. The horizontal part of the fixed base 4.2 is welded to the top of the rope transmission device 4, and the current and signal are introduced from the power transmission channel 2.10 to the rope transmission device 4 through the fixed base 4.2.

[0052] like Figure 8As shown, the rope transmission device 4 includes a roller 4.4 and a hydraulic cable ejector connected by a roller crank 4.5 and a rotating shaft 4.3. Under normal working conditions, the roller 4.4 is placed vertically for conveying ropes on a lifting crane. The hydraulic cable ejector includes a hydraulic actuator 4.1, an ejector 4.6 and a top pressure clamp 4.7 from top to bottom; the hydraulic actuator 4.1 can be ejected downward according to a signal; the ejector 4.6 is generally set as a high-sensitivity spring, and can also be set as other elastic components; the jaws of the top pressure clamp 4.7 are crescent-shaped, which is compatible with the stop layer in the emergency lock device 3. Under normal working conditions, the hydraulic cable ejector is tightened inside the transmission device.

[0053] like Figure 10-11 As shown, a brittle protective layer 3.2 is provided on the top of the emergency cable collapse device 3, which is composed of a polymer material, such as a ceramic material, and can be broken by an instantaneous force of a device such as a top pressure clamp 4.7. The brittle protective layer 3.2 is generally set to a semicircular arc shape with an opening downward, and a rope channel adapted to the crane rope is also provided on the top to prevent the rope from slipping back and forth in the device. The outer surface of the brittle protective layer 3.2 is covered with a friction layer 3.1 made of a high manganese steel series material, which is used to protect the surface of the emergency cable collapse device 3 in contact with the rope from excessive damage caused by long-term sliding friction. A semicircular arc-shaped stop layer 3.6 adapted to the crescent-shaped top pressure clamp jaws is provided below the brittle protective layer 3.2. The stop layer 3.6 is made of a material with high strength and not easy to deform, such as a PVC plastic plate, etc., to limit the lateral displacement of the crane rope. The stop layer 3.6 is wrapped with a viscous damping fluid 3.5 on the outside, which can stick the rope to the clamping point and more effectively prevent it from moving. A cloud-like foam aluminum impact layer 3.4 is also provided at the bottom of the emergency cable-falling device 3 to ensure that the instantaneous high energy given by the hydraulic exciter 4.1 will not cause impact damage to the device, thereby protecting the device.

[0054] In addition, rigid support walls 3.3 of a certain fixed height are arranged on both sides of the emergency cable-falling device 3. There are different models of emergency cable-falling devices 3 according to the different heights of the rigid support walls 3.3. The height can be adjusted according to actual needs to stabilize the upper and lower positions of the rope transmitted inside the entire device.

[0055] In abnormal working conditions, such as Fig. 9As shown, after the roller 4.4 in the rope transmission device 4 works, the rotating shaft 4.3 connected by the roller crank 4.5 is put into the rope transmission device 4; the hydraulic exciter 4.1 in the hydraulic ejection clamp works to give an instantaneous high-energy thrust to quickly eject the top pressure clamp 4.7 welded on the front end of the ejector 4.6, and the top pressure clamp 4.7 works to break the brittle protective layer 3.2 composed of high molecular polymer material on the top of the emergency collapse cable device 3, and clamp the rope into the emergency collapse cable device 3, which has a viscous damping liquid 3.5 inside to wrap part of the crane rope and limit the movement of the rope. At the same time, the crescent-shaped jaws at the end of the top pressure clamp 4.7 clamp the crane rope, and clamp the rope into the stop layer 3.6 matched with the jaws, preventing the rope from moving while making the rope present a downward-opening arc shape, effectively preventing the rope displacement caused by the lateral tension generated by the slippage of the crane rope.

[0056] like Figure 12-14 As shown, the limit block 2 is provided with a limit shell 2.2 with an insulating coating on the outside, and includes several groups of electromagnetic attractors 2.3, current regulators 2.6 and voltage stabilizers connected by wires 2.1. Several groups of electromagnetic attractors 2.3 are fixed on the electromagnetic block fixing frame 2.4, connected to each other and forming an annular rope channel adapted to the diameter of the crane rope. The electromagnetic block fixing frame 2.4 is welded to the upper end of the inner part of the limit block 2. The fixed rope 2.5 passes through the rope channel in the middle of the several groups of electromagnetic attractors 2.3. The voltage stabilizer box 2.7 is welded to the middle end of the inner part of the limit block 2, and is connected to the current regulator 2.6 and the conductive clamp 2.9 through the wire 2.1 and the cable 2.8 respectively, and the conductive clamp 2.9 is connected to the power transmission channel 2.10.

[0057] The limit block 2 has two working states as described below: First, when the device needs to move, the current regulator 2.6 reduces or turns off the current, so that several groups of electromagnetic attractors 2.3 stop locking and controlling the fixed rope 2.5. At this time, the entire present invention can be displaced by the roller 4.4; Second, when the device needs to limit the displacement, the current regulator 2.6 is adjusted to an appropriate level of current, so that several groups of electromagnetic attractors 2.3 have sufficient ability to lock the fixed rope 2.5, and the present invention will be fixed at a suitable position.

[0058] The steps of using the present invention are as follows: first, turn off the current through the current regulator 2.6, and pass the crane ropes in groups through the present invention; then adjust the current regulator 2.6 to make the electromagnetic attractor 2.3 lock the fixed rope 2.5 to fix the position of the present invention. Of course, if the position is found to be unsuitable during use, the current regulator 2.6 can continue to be used to adjust the position; when an emergency occurs, the sliding speed of the crane rope increases suddenly, triggering a pre-set program, starting the emergency locking module, or manually starting the emergency locking module by remote control, emergency braking, preventing the movable rope 10 from continuing to move, and the limit module also immediately starts to limit the displacement of the fixed rope 2.5 to prevent more serious situations from occurring.

[0059] Of course, the above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
