Description

Technical Field

[0001] The utility model relates to the technical field of assembly equipment, in particular to a multi-layer structure test device for anchor winch assembly testing. Background Art

[0002] An anchor winch is a mechanical device used on ships to retract and release anchor chains or cables. It is usually installed at the bow of the ship and is crucial to ensuring that the ship can safely drop and heave anchors. The anchor winch mainly consists of a motor and an anchor chain wheel. The rotating shaft of the anchor chain wheel is connected to the output end of the motor. The anchor winch is installed on the deck of the ship, and the rotating shaft of the anchor chain wheel is arranged vertically. The anchor is lifted and dropped by the coordination of the anchor chain wheel and the ship's anchor chain. The anchor winch needs to undergo no-load tests, load tests and other inspections before being installed on board. The traditional load test method is to install the anchor winch on a test bracket, and use a winch with a load capacity greater than that of the anchor winch to pull against the anchor winch to provide the load, and observe the working performance of the anchor winch.

[0003] Patent application number CN201610761255.9 discloses a load test system for an anchor winch, which relates to the field of marine engineering technology. The test system comprises a test base, a mounting platform, a power unit, a tooling anchor chain, a mobile pulley, a fixed pulley block, a wire rope, a load tower, and a load weight. The tooling anchor chain is connected to the anchor chain pulley of the anchor winch in a transmission manner. The mobile pulley is horizontally slidably mounted on the test base. One end of the mobile pulley is provided with a plurality of parallel pulleys. The other end of the mobile pulley is connected to the fixed end of the tooling anchor chain. The fixed pulley block is fixed to the side of the mobile pulley away from the anchor winch. A first guide pulley is provided at the top of the load tower. The fixed end of the wire rope is fixed to the fixed pulley block. The free end of the wire rope passes around the pulleys on the mobile pulley and the fixed pulley block, then around the first guide pulley at the top of the load tower and hangs vertically.

[0026] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0027] Example 1:

[0028] A multi-layer structure test device for anchor winch assembly test, comprising a cylinder 1, the axis of which is arranged in a vertical direction, for forming an installation space for installing the anchor winch; Figure 1 As shown, the capstan head 9 is installed in the test device from the upper side, and the capstan motor 10 on the lower side can be installed upward from the bottom of the test platform to the lower end of the cylinder 1, and the capstan head 9 and the capstan motor 10 are connected inside the cylinder 1;

[0029] The multi-layer platform 2, the cylinder 1 vertically passes through each platform plate of the multi-layer platform 2 and is fixedly connected, and the platform plate forms an expanded multi-layer installation space or installation plane around the cylinder 1 for installing the distribution equipment of the load test; Figure 1 、 2 As shown, each platform plate is arranged in parallel. The multi-layer structure test device of the present invention is convenient for installing multiple layers of anchor winches with complex structures. The parallelism and coaxiality of the relative installation surfaces of the multi-layer platform 2 are required to be high, and the safety and convenience of assembly can be guaranteed. Figure 1 As shown, the device can be installed on the test platform and can ensure the stability of the lifting and can withstand the required rated load during the test.

[0030] The base plate 3, the cylinder 1 and the multi-layer platform 2 are fixedly installed on the base plate 3 based on the base plate 3. The base plate 3 is provided with anchor bolt holes 4 connected to the test platform around it. The device is fixed as a whole on the test platform of the test site, and is firmly fixed to the bottom surface of the test platform through the anchor bolt holes 4, which can provide a stable lateral load bearing capacity.

[0031] Furthermore, the multi-layer platform 2 is provided with three layers of platform plates from top to bottom, such as Figure 1-3 As shown, the first plate layer 5, the second plate layer 6, and the third plate layer 7 are arranged in a staggered arrangement. Through holes for mounting the cylinder 1 are provided at the same position throughout the three-layer platform plate. The three-layer platform plate is a T-shaped structure, comprising a transverse plate 12 and a longitudinal plate 13. The center lines of the longitudinal plates 13 of the three-layer platform plate are in the same vertical plane, and the center lines are parallel. In specific implementation, with the cylinder 1 as the reference, the three-layer plate layer is sleeved on the cylinder 1 through the through holes and welded to the cylinder 1. The upper and lower ring plates are welded to the ends of the cylinder 1. The bottom plate 3 is welded to the three-layer plate layer with multiple ribs 11.

[0032] Several ribs 11 are provided between the various platform plates of the multi-layer platform 2, and between the bottom platform plate and the bottom plate 3. Ribs 11 are distributed horizontally or vertically between the plate layers. Between the upper and lower layers, the ribs 11 are positioned in a corresponding manner, which not only improves the overall firmness of the test device, but also greatly increases the lateral stiffness of the device. All three layers of panels are T-shaped, avoiding sufficient welding locations and processing space. Figure 3As shown, the outer dimensions of the platform plate are 3000×4000 mm.

[0033] Furthermore, the two ends of the cylinder 1 are respectively provided with ring plates, the upper ring plate 24 is installed on the upper side of the first plate layer 5, and the lower ring plate 25 is installed on the lower side of the third plate layer 7. The plate layers at both ends are used to fix the capstan head 9 and the capstan motor 10 of the anchor winch. The specific installation diagram is shown in FIG. Figure 1 As shown, the interior of the cylinder 1 is used to set the main shaft and coupling between the winch head 9 and the winch motor 10. The equipment or sling for installing the anchor winch can be set on the upper side of the first plate layer 5 to meet the strength requirements;

[0034] Specifically, such as Figure 2 As shown, the transverse plates 12 of the three layers of platform plates have the same length, and the width of the transverse plates 12 gradually increases from top to bottom, so that the transverse plates 12 of the second plate layer 6 form a laterally protruding middle platform 14 on both sides of the longitudinal plate 13. The bottom of the middle platform 14 on both sides of the second plate layer 6 is provided with a bracket platform 15. The bracket platform 15 can provide a mounting base for the anchor winch auxiliary equipment installed on the lower ring plate of the anchor winch, which can meet the assembly test needs of different types of anchor winches; a number of ribs 11 are provided between the bracket platform 15 and the second plate layer 6 to reinforce the bracket platform 15, and the third plate layer 7 is provided with a avoidance hole 16 at a position corresponding to the bracket platform 15; the installation of the anchor winch auxiliary equipment extends downward through the avoidance hole 16 to the lower end ring plate 25 to provide connection space with the lower end equipment of the anchor winch.

[0035] This multi-layer structure test device meets the multi-layer installation requirements of marine anchor winches, and the T-shaped panel can meet the installation and use requirements of symmetrical structure equipment.

[0036] Example 2:

[0037] Since the center heights of different anchor winch devices are different, the multi-layer structure test device manufactured in this embodiment is convenient for the assembly test requirements of the same type of anchor winch devices of different sizes, and can be disassembled after completing the functional test to meet the needs of different batches of equipment.

[0038] Specifically, the ring plate is provided with a flange hole 17, and a variable aperture plate 18 is installed on the ring plate through the flange hole 17. For different sizes of anchor winches, the flange diameters of the mounting surface are different. In this embodiment, a replaceable variable aperture plate 18 is provided, which can be changed for anchor winch flanges of different diameters, such as Figure 4As shown, the outer ring of the variable aperture plate 18 is provided with an outer ring hole 19 that cooperates with the flange hole 17, and the inner ring is provided with an inner ring hole 20 that cooperates with the anchor winch. The outer ring hole 19 is connected to the flange hole 17 on the ring plate, and the inner ring hole 20 is used to connect to the flange surface of the anchor winch. The inner diameter of the variable aperture plate 18 is adjustable to meet the diameter variation of the cylinder 1 of the anchor winch between 800-1200mm.

[0039] Furthermore, the cylinder body 1 includes a base cylinder 21 and a telescopic cylinder 22. The base cylinder 21 is sleeved on the outer wall of the telescopic cylinder 22, so that the telescopic cylinder 22 can be adjusted in the axial direction relative to the base cylinder 21. Since the center heights of different anchor winches are different, in this embodiment, the installation height of the anchor winch can be changed by adjusting the telescopic cylinder 22, so that precise adaptive adjustment can be performed. Specifically, Figure 4 、 5 As shown, the multi-layer platform 2 is provided with a driving cylinder 23, and multiple driving cylinders 23 are arranged around the cylinder 1, and the free ends of the driving cylinders 23 are connected to the bottom surface of the upper ring plate; when controlled, the height position of the upper end ring plate 24 can be changed by simultaneously controlling the driving cylinders 23 to extend and retract, thereby adapting to the assembly requirements of different types of anchor winches, so that the height of the ring plate can be adjusted within the range of 800-1000mm.

[0040] 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 principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
