It is usually installed at the bow of the ship and is essential to ensure that the ship can safely drop and anchor. The anchor winch mainly includes a motor and an anchor chain wheel. The rotating shaft of the anchor chain wheel is connected to the output end of the motor by transmission. 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. Before the anchor winch is installed on board, it needs to undergo no-load tests, load tests and other inspections.

The multi-layer structure test device of the present invention is convenient for installing multiple layers of anchor winches with complex structures. The relative parallelism and coaxiality 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 withstand the required rated load during the test.

[0020] The bottom plate 3, the cylinder 1 and the multi-layer platform 2 are fixedly installed on the bottom plate 3 based on the bottom plate 3, and the bottom 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, so as to provide a stable lateral load bearing capacity.

[0021] 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 an intermittent stacking arrangement, and a through hole for installing the cylinder 1 is provided at the same position through the three-layer platform plate. The three-layer platform plate is a T-shaped structure, which includes a transverse plate 12 and a longitudinal plate 13. The center lines of the longitudinal plates 13 of the three-layer platform plate are on the same vertical plane, and the center lines are parallel. In specific implementation, the cylinder 1 is used as a reference, and the three-layer plate layer is sleeved on the cylinder 1 through the through hole and welded to the cylinder 1. The upper and lower ring plates are welded to the two ends of the cylinder 1, and the bottom plate 3 and the three-layer plate layer are welded with multiple rib plates 11.

[0022] Several ribs 11 are arranged between the various platform plates of the multi-layer platform 2, and between the bottom platform plate and the bottom plate 3. Several ribs 11 are distributed horizontally or vertically between the plate layers, and the positions of the ribs 11 correspond between the upper and lower layers, which can not only improve the overall firmness of the test device, but also greatly increase the lateral stiffness of the device; the three-layer panel is a T-shaped structure, avoiding sufficient welding positions and processing space. Figure 3 As shown, the outer dimensions of the platform plate are 3000×4000mm.

[0023] 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 respectively used to fix the capstan head 9 and the capstan motor 10 of the anchor winch. The specific installation diagram is shown in Figure 1 As shown, the interior of the cylinder 1 is used to set the main shaft and coupling between the capstan head 9 and the capstan motor 10. The equipment or sling for installing the anchor capstan can be set on the upper side of the first plate layer 5 to meet the strength requirements; Specifically, Figure 2 As shown, the length of the transverse plates 12 of the three-layer platform plate is the same, and the width of the transverse plates 12 increases step by step from top to bottom, and the transverse plates 12 of the second plate layer 6 form a middle platform 14 protruding laterally on both sides of the longitudinal plate 13.

[0024] 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. Embodiment 2

[0025] 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.

[0026] 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 anchor winches of different sizes and models, the flange diameters of the mounting surface are different. In this embodiment, the replaceable variable aperture plate 18 can be changed for anchor winches with different diameters, such as Figure 4 As shown, an outer circle hole 19 matching with the flange hole 17 is provided on the outer circle of the variable aperture plate 18, and an inner circle hole 20 matching with the anchor winch is provided on the inner circle. The outer circle hole 19 is connected to the flange hole 17 on the ring plate, and the inner circle hole 20 is used to connect with 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 within 800-1200mm.

[0027] 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 a plurality of 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 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.

[0028] 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 the scope of protection of the present invention.
