Description

Technical Field

[0001] The present invention belongs to the field of ship equipment design, and relates to the design, layout and installation of an integrated vertical guiding pulley device capable of two-way rope payout. Background Art

[0002] Crane ships generally set positioning anchors at the bow and stern for ship movement and positioning during crane operations. The positioning mode of this ship is 8-point mooring positioning, so 8 sets of positioning anchor equipment are provided. However, the deck space at the bow and stern of the crane ship is limited. In addition to the positioning anchor equipment, navigation anchor equipment, mooring equipment, lifting equipment and other outfittings also need to be arranged on the deck surface. It is difficult to set 8 positioning anchor winches on the deck surface. Therefore, the positioning anchor winches of this ship are arranged in the winch compartment under the deck. After the positioning anchor cables are payout horizontally from the winches, they are guided by vertical guiding pulleys in the compartment and then pass through the deck surface, and then are guided by vertical guiding pulleys and horizontal guiding pulleys on the deck surface to reach the side fairlead, as Figure 1 and Figure 2 shown. Usually, the vertical guiding pulley is directly welded on the deck surface and can only payout ropes in one fixed direction. To change the rope payout direction, several additional horizontal guiding pulleys need to be set on the rope payout path. Due to the requirements of construction operations on this ship, in addition to the need for the anchor cable to payout at the bow, it also needs to payout at the side. If traditional vertical guiding pulleys are used, 2 horizontal guiding pulleys need to be set on the rope payout path, as Figure 3 shown. This not only increases the quantity of equipment, resulting in higher equipment costs and installation costs; secondly, after the anchor cable is guided multiple times, its rope payout path is extended. The deck space is already very limited, and the long rope payout path seriously affects the layout of other equipment, and affects personnel passage and operations, reducing the efficiency and safety of deck operations; finally, the more horizontal guiding pulleys the anchor cable passes through, the more serious its wear will be, reducing the service life of the anchor cable.

[0003] In order to meet the requirements of guiding the anchor cable in different directions after it is payout from the vertical guiding pulley, reduce the quantity of equipment, reduce the number of times of guiding the anchor cable, simplify the guiding path of the anchor cable, reduce equipment costs and installation costs, improve the utilization rate of the deck surface, and extend the service life of the anchor cable, there is an urgent need to provide a new solution and tool with good social and economic benefits. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and seek a simple, reasonable and efficient solution and device for guiding the anchor cable in different directions at a relatively low cost. By designing an integrated vertical guiding pulley device capable of two-way rope payout, the requirement of guiding the anchor cable in different directions after it is led out from the same rope payout point is met.

[0005] To achieve the above object, the technical solution of the present invention provides an integrated vertical guiding pulley device with bidirectional rope payout, including a structural frame and guiding pulleys; two of the guiding pulleys are spaced on the structural frame, and the guiding pulleys are arranged in a staggered manner with different heights; the lateral distance between the rope grooves of the two guiding pulleys allows the cable anchor to pass through. After the cable anchor vertically pays out from the deck surface, it is horizontally led out through the top rope groove of any one of the guiding pulleys, and the cable anchor can be lifted from the rope groove and introduced into the top rope groove of the other guiding pulley in the opposite direction to change the direction of the cable anchor payout.

[0006] Preferably, the projections of the centers of the rope grooves of the two guiding pulleys on the deck surface coincide with the center of the deck rope outlet.

[0007] Preferably, the guiding pulley includes a rotating mechanism arranged on the structural frame and a pulley body arranged on the rotating mechanism.

[0008] Preferably, the rotating mechanism includes a main shaft arranged on the structural frame, a spherical roller bearing arranged on the main shaft, and a bearing seal cover arranged on the spherical roller bearing.

[0009] Preferably, a guiding limit roller is detachably connected directly above each of the guiding pulleys on the structural frame to prevent the cable anchor from jumping out of the rope groove during the movement in the rope groove.

[0010] Preferably, the structural frame includes a vertically arranged base web, a base panel horizontally arranged on the top of the base web, and a support plate vertically arranged on the base panel, and the guiding pulley is arranged between two parallel support plates.

[0011] Preferably, the number of the support plates corresponds to the number of the base webs, and the two are vertically aligned.

[0012] Preferably, on one side where the two parallel support plates are away from each other, a lateral gusset plate one is connected to the base panel to bear lateral forces; on one side where the two parallel base webs are away from each other, a lateral gusset plate two is connected to the base panel to bear lateral forces.

[0013] Preferably, the number of the lateral gusset plate one corresponds to the number of the lateral gusset plate two, and the two are vertically aligned to transfer forces.

[0014] Preferably, the main structure of the structural frame is welded by steel plates and is directly welded to the deck for installation as a whole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The vertical guiding pulley of the present invention can meet the two-way rope outlet requirements after the cable anchor is vertically led out from the deck surface by setting two guiding pulleys, the upper and lower ones, at different heights and arranged staggeredly. It can effectively reduce the number of devices, reduce the number of cable anchor guiding times, simplify the cable anchor guiding path, reduce the equipment cost and installation cost, improve the utilization rate of the deck surface, extend the service life of the cable anchor, and the overall operation process is simple.

[0017] The vertical guiding pulley of the present invention adopts an integrated design. The structural body and the structural base are welded together through the base panel to jointly form a structural framework. The upper guiding pulley and the lower guiding pulley are integrated on the structural framework through reasonable arrangement, forming an integrated vertical guiding pulley device with one structural framework, two guiding pulleys, and two rope outlet directions. Finally, it is integrally welded on the deck surface to achieve the task of two-way rope outlet with two pulleys on one structural framework at the same time.

[0018] The vertical guiding pulley of the present invention is provided with two guiding pulleys, the upper and lower ones. The two pulleys are at different heights and are arranged staggeredly by setting a height difference, so that the center of the rope groove of the upper pulley and the center of the rope groove of the lower pulley coincide in the projection on the deck surface and also coincide with the center of the deck rope outlet. In this way, after the cable anchor vertically exits the rope from the deck surface, it can directly and smoothly enter the rope groove of the lower pulley or the upper pulley without bending and deflection. After being guided by the lower pulley, the cable anchor can exit the rope forward, and after being guided by the upper pulley, the cable anchor can exit the rope backward, thus realizing the two-way rope outlet after the cable anchor is vertically led out from the deck surface.

[0019] The vertical guiding pulley of the present invention is provided with guiding limit rollers at the top, which can prevent the cable anchor from jumping out of the rope groove during the movement in the rope groove. The guiding limit rollers are detachable. When it is necessary to change the rope outlet direction of the cable anchor, just unscrew the bolts, remove the rollers, and directly lift the horizontal section of the cable anchor in the rope outlet direction from the rope groove at the top of one pulley and import it into the rope groove at the top of the other pulley in the opposite direction. During the transfer of the cable anchor, only the horizontal section of the cable anchor in the rope outlet direction is transferred, and the vertical section of the cable anchor in the rope inlet direction does not move or change at all and always remains in the rope grooves of the upper and lower guiding pulleys, and the cable anchor does not jump out of the pulley rope groove, greatly simplifying the work of winding the rope. Therefore, the entire process of turning the cable anchor is simple to operate. Just remove the rollers at the top of the pulley, lift the horizontal section of the cable anchor in the rope outlet direction and import it into the rope groove at the top of the other pulley in the opposite direction. There is no need to detach the cable anchor from the pulley and rewind the rope, no need to carry the heavy cable anchor on the deck surface, no need to carry out heavy cable guiding work, and no need to move, adjust or disassemble the vertical guiding pulley device, significantly improving the operation efficiency.

[0020] The main structure of the vertical guiding pulley of the present invention is composed of welded steel plates. Only two guiding pulleys at different heights and arranged staggeredly can complete the two-way rope outlet task at the same rope outlet point. The overall structure is simple, easy to manufacture and convenient to install.

[0021] The vertical guiding pulley of the present invention can complete the task of double-direction rope payout at the same rope payout point, eliminating the need for additional guiding devices for multiple guidances, simplifying the guiding path of the cable anchor, and improving the utilization rate of the deck surface.

[0033] The embodiments of the present invention disclose the design, layout and installation of an integrated vertical guiding pulley device with bidirectional rope outlet, which is mainly used for crane ships and other engineering ships or transport ships with the same requirements. The pulley is arranged on the rope outlet path of the cable anchor. By reasonably setting two pulleys with a height difference, the requirements for guiding the cable anchor in different directions after being led out from the same rope outlet point are met, thereby reducing the number of devices, simplifying the cable anchor guiding path, improving the utilization rate of the deck surface, and prolonging the service life of the cable anchor.

[0034] The integrated vertical guiding pulley device with bidirectional rope outlet mainly includes a structural body, a structural base, an upper guiding pulley 6, a lower guiding pulley 7, a spherical roller bearing 9, a main shaft 11, a guiding limit roller 13, an oil nozzle 15 and a detachable flange sealing device 14, etc.

[0035] The structural body includes a supporting plate 1 and a lateral gusset plate one 2. The supporting plate 1 is composed of two parallel steel plates. The guiding pulley is placed between the supporting plates 1. The main shaft 11 of the guiding pulley passes through the two supporting plates 1 and is fixed on the supporting plate 1 through mounting bolts 12. Lateral gusset plate one 2 is provided on one side of the two supporting plates 1 away from each other and is connected to the top surface of the base panel 5. A total of 12 lateral gusset plate one 2 are provided to bear the lateral force.

[0036] The structural base includes a base web 3, a lateral gusset plate two 4 and a base panel 5. The base web 3 is also composed of two parallel steel plates. The base web 3 and the supporting plate 1 need to be aligned vertically to better transfer the force. Lateral gusset plate two 4 is provided on one side of the two base webs 3 away from each other and is connected to the bottom surface of the base panel 5. A total of 12 lateral gusset plate two 4 are provided to bear the lateral force. The lateral gusset plate one 2 of the structural body and the lateral gusset plate two 4 of the structural base need to be aligned vertically to better transfer the force.

[0037] The guiding pulley includes a pulley body 8, a spherical roller bearing 9, a bearing sealing cover 10, a main shaft 11 and mounting bolts 12. A rotating mechanism composed of the main shaft 11 and the bearing is set at the rotation center of the pulley. The rotating mechanism is fixed on the supporting plate 1 through bolts. The pulley can rotate around the rotating mechanism, and the force is transmitted to the structural body and the structural base through the rotating mechanism. The bearing includes a spherical roller bearing 9 and a bearing sealing cover 10.

[0038] The vertical guiding pulley adopts an integrated design. The supporting plate 1 and the lateral elbow plate 1 are welded to each other to form the structural body. The base web 3, the lateral elbow plate 2 and the base panel 5 are welded to each other to form the structural base. Then the structural body is integrally welded to the structural base to jointly form the structural framework. The upper guiding pulley 6 and the lower guiding pulley 7 are integrated on the structural framework through reasonable arrangement, forming an integrated vertical guiding pulley device with one structural framework, two guiding pulleys and two rope outlet directions. Finally, it is integrally welded on the deck surface to achieve the task of double-direction rope outlet with two pulleys on one structural framework at the same time.

[0039] The vertical guiding pulley is provided with two guiding pulleys, the upper and the lower, which are located in the same vertical plane. The two pulleys are at different heights and are arranged staggeredly by setting a height difference. The center of the rope groove of the upper pulley and the center of the rope groove of the lower pulley can coincide in the projection on the deck surface, and the centers of the rope grooves of the upper and lower pulleys should coincide with the center of the rope outlet on the deck surface. In this way, after the cable anchor rope exits vertically from the deck surface, it can directly and smoothly enter the rope groove of the lower pulley or the upper pulley without bending and deflection. The cable anchor rope can exit forward after entering the rope groove of the lower pulley and being guided by the lower pulley, and the cable anchor rope can exit backward after entering the rope groove of the upper pulley and being guided by the upper pulley, so as to achieve the double-direction rope outlet after the cable anchor rope is vertically led out from the deck surface.

The roller core shaft passes through the two supporting plates 1 and is fixed to the supporting plates 1 by bolts. The rollers can rotate around the core shaft to prevent the cable anchor rope from jumping out of the rope groove during the movement in the rope groove. The guiding and limiting rollers 13 are detachable. When it is necessary to transfer the cable anchor rope from one pulley to the other pulley for rope outlet, the bolts are unscrewed, the rollers are removed, the cable anchor rope is directly lifted from the top rope groove of the pulley and then led into the top rope groove of the other pulley in the opposite direction. Finally, the rollers are reinstalled.

[0041] Through the above design, the integrated vertical guiding pulley device with double-direction rope outlet of the present invention can complete the task of double-direction rope outlet with two pulleys on one structural framework at the same time. By arranging the upper and lower guiding pulleys at different heights and staggeredly, the cable anchor rope can directly and smoothly enter the rope groove of the upper pulley or the lower pulley without bending and deflection after exiting vertically from the deck surface, completing the double-direction rope outlet after the cable anchor rope is vertically led out from the same rope outlet. There is no need to set additional guiding equipment, reducing the number of times of guiding the cable anchor rope, simplifying the guiding path of the cable anchor rope, improving the utilization rate of the deck surface and prolonging the service life of the cable anchor rope.

[0042] When it is necessary to change the rope outlet direction of the cable anchor, just remove the guiding and limiting roller 13 at the top of the pulley, directly lift the cable anchor from the rope groove at the top of one pulley and then import it into the rope groove at the top of the other pulley in the opposite direction. The whole process of turning the cable anchor is simple. There is no need to detach the cable anchor from the pulley and rewind the rope, no need to carry the heavy cable anchor on the deck surface, no need to conduct heavy cable guiding work, and no need to move, adjust or disassemble the vertical guiding pulley device, which significantly improves the operation efficiency.

[0043] The main structure of the vertical guiding pulley is composed of welded steel plates and is directly welded and installed on the deck as a whole. It has a simple structure, is convenient to manufacture and install, can be applied to more application scenarios, and has good social and economic benefits.
