Description

Technical Field

[0001] This utility model relates to the field of anchor winch base design, and in particular to an anchor winch including a novel base. Background Technology

[0002] like Figures 1-3 As shown, the mainstream design of the anchor winch box base in the existing technology is a box structure, which is composed of 5 steel plates. The upper steel plate is usually designed to be thicker, generally around 50-70 mm, in order to install fixing bolts and ensure connection strength. The gross weight of a single box base is about 75-130 kg. Figure 4 As shown, each anchor winch is equipped with two box-type bases, and the total weight of the bases alone is approximately 150-260 kg.

[0003] The main manufacturing process of the box-type base is as follows: material cutting and shaping - welding - sandblasting - primer spraying - milling steps and planes - drilling bottom holes - tapping threads. It needs to be connected to the anchor winch box with 3-5 bolts.

[0004] After being assembled with the container, the anchor winch is placed on the deck. At this point, the center height of the anchor winch needs to be adjusted. This is done by cutting the base to lower its height. The cutting and adjustment process is very tedious and takes up a lot of manpower and time. After the center height is adjusted, the base is welded to the deck around its perimeter to complete the fixed installation of the entire machine.

[0005] like Figures 1-4 As shown, the existing anchor winch box-type base is a box structure, using large-sized materials, resulting in heavy weight and high strength; it also has a large contact area and good stability. However, the main disadvantage of this box-type base is its high material consumption and cost. It also requires two machining processes, leading to higher manufacturing costs. During anchor winch installation, users have to spend a lot of manpower and time on cutting and adjusting, resulting in low work efficiency. Utility Model Content

[0006] The purpose of this invention is to provide an anchor winch incorporating a novel base. The overall structure of the novel base provided by this invention is simpler than previous bases, with each base consisting of only two steel plates, significantly reducing material usage and manufacturing costs. While reducing material usage and costs, it still maintains excellent stability and high fatigue and tensile stress resistance, demonstrating excellent technical and economic efficiency.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] An anchor winch incorporating a novel base, the anchor winch comprising an anchor winch body and the novel base,

[0009] The novel base includes mutually perpendicular support plates and a main load-bearing plate.

[0010] The main load-bearing plate is provided with mating holes, and the new type of base is installed at the bottom of the anchor winch body through the mating holes.

[0011] In one embodiment of this utility model, the thickness of the supporting plate is 10-12mm, and the thickness of the main load-bearing plate is 20-25mm.

[0012] In one embodiment of this utility model, the cross-sectional shape of the supporting plate is composed of a trapezoid and an inverted concave shape, and the cross-sectional shape of the main load-bearing plate is a deformed sector shape.

[0013] In one embodiment of this utility model, the supporting plate has bevels at both ends, one end of the main force plate is vertically welded to the supporting plate, and the other end of the main force plate has a bevel.

[0014] In one embodiment of this utility model, the supporting upright plate and the main load-bearing plate are both made of steel plate, and the steel plate is of model S355J2.

[0015] In one embodiment of this utility model, the anchor winch body includes a gearbox, and two novel bases are provided below the gearbox along the diagonal direction of the gearbox.

[0016] In one embodiment of this utility model, the gearbox is composed of a front plate, a rear plate, a top plate, a bottom plate, and two side plates, and the two novel bases are respectively fixed to one side plate by a pin.

[0017] In one embodiment of this utility model, the two side plates are provided with through holes, and the pin passes through the through holes and the mating holes in sequence to fix the novel base to the side plates.

[0018] In one embodiment of this utility model, the gap between the mating hole and the pin is 0.03 to 0.05 mm.

[0019] In one embodiment of this utility model, the anchor winch body further includes a support base, and two novel bases are provided below the support base. The gearbox is connected to the support base through a steel pipe.

[0020] As a preferred technical solution, the specific structural design of the anchor winch body is a conventional technical solution, which does not involve the innovative points of this utility model, and will not be described in detail in this case.

[0021] The working principle of this utility model is as follows:

[0022] When the anchor winch is working, the tension transmitted by the anchor chain or cable acts on the pin connecting the new base of the anchor winch and the gearbox through the gearbox side plate. The pin transmits the tension to the main load-bearing plate of the new base. At this time, the upper half of the mating hole on the main load-bearing plate bears the pressure from the pin, and the lower half of the mating hole on the main load-bearing plate bears the tension from the pin.

[0023] The maximum stress section is the equilibrium surface between the upper and lower parts. After calculating the corresponding force values, the thickness of the supporting plate and the main stress plate, as well as the size and type of the weld, are determined.

[0024] The pin bearing is subjected to shear forces from the gearbox side plate and the main load-bearing plate. The diameter of the pin is determined through modeling and calculation.

[0025] Based on the above analysis and calculation, the allowable stress of the main load-bearing plate thickness and the pin shaft is greater than the working stress. The safety factor selected during the calculation process is in the range of 3 to 8, which fully meets the working strength requirements.

[0026] By analyzing the stress at each point of the anchor winch during operation, the maximum values ​​of the horizontal and vertical components of each support point under the most unfavorable conditions were determined. The new base structure was designed as two mutually perpendicular steel plates welded together. The base is welded to the deck to form a stable support structure with the deck, which can withstand the combined action of the horizontal and vertical components of the anchor winch.

[0027] The stress conditions of the support plates and main load-bearing plates of each new base were analyzed, and the strength and tensile stress of the steel plates were checked in detail. An appropriate safety factor was selected, and the thickness of the base steel plates and gearbox side plates was determined. S355J2 hot-rolled structural steel was selected as the material. The connecting pins were made of 42CrMo alloy structural steel and subjected to quenching and tempering treatment, and were fabricated according to the drawings.

[0028] The new base has only two units arranged diagonally below the gearbox, with a total weight of about 17-30 kg. This is about 141-220 kg lighter than the base in the existing technology, which is only 10% of the original base weight. Although the weight is reduced by about 90%, the strength is not reduced, the stability is still good, and it can withstand the maximum load during operation.

[0029] The original base used 8 bolts for connection, while the new base uses 2 pins. The weight is similar, but the cost is slightly higher than that of the bolts. The total cost of the new base is much lower than that of the original base.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. This utility model optimizes the structure of the new base. Each new base consists of only 2 steel plates, eliminating redundant parts and greatly reducing the amount of material used. At the same time, it can effectively withstand the working load of the anchor winch while maintaining stability and strength.

[0032] 2. The overall structure of the new base provided by this utility model is simpler than that of the previous base, the amount of material used is greatly reduced, and the manufacturing cost is greatly reduced. While reducing the use of materials and reducing costs, it still maintains good stability and high fatigue resistance and tensile stress strength, and has good technical and economic efficiency.

[0033] 3. The thickness of the two steel plates of the new base in this utility model can be flexibly adjusted according to the working load changes of different models of anchor winches, making the design work convenient and efficient.

[0034] 4. By using the new base provided by this utility model, when adjusting the center height of the anchor winch during installation, only 2 steel plates need to be cut for each base, which reduces the amount of cutting work, increases work efficiency, and reduces the probability of the height of each steel plate exceeding the tolerance after cutting, thus ensuring adjustment accuracy.

[0035] 5. In this utility model, each new base corresponds to only a single stress point. The thickness of one or two steel plates can be increased in a targeted manner according to the force value and direction of each stress point to increase the allowable stress. The structure is flexible, the manufacturing difficulty is low, and the material consumption is much lower than that of the original box-type base. The structure is flexible and highly adaptable, and can be modified according to the needs of different scenarios. Attached Figure Description
