Description

Technical Field

[0001] This utility model belongs to the technical field of marine equipment, specifically relating to an opening device for the housing of an anchor winch motor brake. Background Technology

[0002] Anchor winches are key pieces of equipment on ships used for raising and lowering anchors and anchor chains. They play an indispensable role in operations such as berthing, setting sail, and positioning at sea. When a ship needs to berth, the anchor winch releases the anchor and anchor chain, causing the anchor to sink to the seabed and securing the ship's position using the anchor's holding power. When setting sail or needing to change position, the anchor winch can quickly retrieve the anchor and anchor chain.

[0003] Anchor winches can be mainly classified into steam winches, hydraulic winches, and electric winches according to their power source. Steam winches were widely used on early ships, utilizing steam power to drive their operation. They offer significant power output, but due to the need for specialized steam generators, their equipment is complex and maintenance costs are high, leading to their reduced use today. Hydraulic winches, on the other hand, are driven by the pressure energy of a hydraulic system. Their advantages include providing stable and high torque, enabling smooth anchor chain retrieval and deployment. However, hydraulic systems also suffer from complex components and a tendency to leak. Electric winches have gradually become mainstream with the development of electrical technology. Driven by an electric motor, they offer numerous advantages such as relatively simple structure, convenient operation, ease of control, and energy efficiency, making them widely used on modern ships.

[0004] For electric anchor winches, the installation of brakes is crucial. On one hand, when ships are sailing at sea, adverse environmental factors such as wind and waves can cause them to roll and pitch. Without brakes, the anchor winch may accidentally rotate due to the ship's movement when not in operation, potentially leading to loosening or slippage of the anchor chain, seriously threatening ship safety. On the other hand, during the process of raising and lowering the anchor chain, the brakes can promptly stop the chain or control its lowering speed when an emergency stop is needed, preventing the anchor chain from becoming uncontrollable due to inertia or other unforeseen factors.

[0005] Therefore, the quality of the brake components determines the service life of the brake system. Poor-quality components wear out more easily and will wear out faster over the same working time. Higher-quality brake components (such as original manufacturer spare parts) have better durability, extending the replacement cycle and improving the reliability of the anchor winch equipment.

[0006] However, the brakes of electric anchor winches also have some common problems in actual use. These mainly include: after the anchor winch has been running for a certain period, debris and powder will be generated on the friction surface of the brake components. Depending on the frequency of use, the motor rear cover needs to be opened periodically for cleaning; otherwise, the accumulated debris will enter the friction gap, causing the brake to malfunction. Opening the motor rear cover is a significant undertaking, and improper assembly can easily damage the seal of the motor rear cover and alter the brake clearance.

[0007] Currently, a common approach to addressing the above issues in existing technology is to create process holes in the lower housing of the brake component at the rear of the motor. During dust removal, compressed air is used to blow away dust from other bolt holes, and the process holes are sealed with plugs during normal operation. This avoids frequent disassembly of the motor's rear cover, reducing workload and facilitating routine maintenance. However, this requires design and manufacturing during the production stage. For some existing equipment, replacing the anchor winch's brake or customizing a new brake housing significantly increases costs. A more suitable approach is to create holes in the brake housing using a drilling device to meet the above requirements. However, this presents another problem: commercially available drilling devices are not compatible with the motor brake housing, and finding a suitable machining center for drilling using a multi-axis machining center is difficult, and costs are also hard to control.

[0008] In summary, there is a need for a drilling device that is simple in structure, low in cost, and adaptable to the aforementioned drilling scenarios, so as to achieve low-cost retrofitting of old equipment. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] In the description of this utility model, it should be understood that the relative relationships indicated by terms such as "front" and "rear" are based on the corresponding relationships when the device is installed in actual applications. They are used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific position. Therefore, they should not be construed as limitations on this utility model.

[0044] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] It should be noted that, unless otherwise specified, the methods used in this utility model are conventional methods; and the raw materials and equipment used are, unless otherwise specified, conventional commercially available products.

[0046] This embodiment provides a method such as Figure 1 and Figure 2 The diagram shows an anchor winch motor brake housing opening device, which includes a rotary chuck 1 and a movable drill rig 2.

[0047] This embodiment uses a common brake housing as an example for illustration, such as... Figure 3 As shown, the brake housing 4 is a regular cylindrical structure with only outward-folded edges at the ends. This type of housing is relatively easy to process. However, in actual work, some brake housings have irregular protrusions, or the housing is designed with a reduced diameter section based on space considerations, which results in the area where the processing holes are located not being on a regular cylindrical arc surface. The housing structure shown in this embodiment is for the convenience of understanding this embodiment and should not be construed as a limitation.

[0048] Among them, combined Figure 4 As shown, the rotary chuck 1 in this embodiment includes a turntable 101 and a multi-jaw chuck 102, and the multi-jaw chuck 102 is coaxially mounted on the turntable 101, thereby achieving rotational operation through external power drive, which facilitates workpiece positioning.

[0049] The multi-jaw chuck 102 holds the brake housing to be processed. Furthermore, to enable temporary fixing of brake housings with different structures, the multi-jaw chuck in this embodiment is a three-jaw or four-jaw chuck, and the jaws are separate jaws. Each set of jaws includes a basic jaw 103 and a top jaw 104. The top jaw 104 is detachably connected to the basic jaw 103 by bolts. This allows for easy adaptation of irregular brake housings; only the corresponding top jaw 104 needs to be replaced, thus reducing design costs. In this embodiment, based on the aforementioned brake housing 4, the top jaw 104 can adopt a common three-section structure.

[0050] A pitching mechanism 3 is also provided between the rotary chuck 1 and the movable drill rig 2.

[0051] Among them, combined Figure 4 and Figure 5 As shown, the pitch mechanism 3 in this embodiment is provided with a rotating part, a locking part, and a supporting part.

[0052] Furthermore, the support section is a planar square frame structure 303, specifically formed by welding and splicing square profiles, with at least one short side and two long sides. The support section is fixedly connected to the fixed end of the movable drilling platform.

[0053] The rotating part includes a lug 301 and a rotating shaft. The lug 301 is fixedly connected to the bottom surface of the turntable 101 and is set vertically downward. The two long sides of the planar square frame structure 303 clamp the lug 301, and a first through hole is machined near the end. The rotating shaft passes through the first through hole of the long side and the lug to form a rotating connection relationship, and the plane of the rotation direction is perpendicular to the horizontal plane.

[0054] A locking part is also provided between the support part and the fixed end of the rotating chuck. The locking part includes an arc-shaped edge; multiple locking holes are provided circumferentially on the arc-shaped edge; the end of the support part is provided with at least one through hole and is connected to at least one locking hole by a fastener. Preferably, in this embodiment, an arc-shaped edge 302 is provided on the lower surface of the turntable 101. Similarly, the two long sides of the planar square frame structure 303 sandwich the arc-shaped edge 302, and a groove is machined along the arc on the arc-shaped edge 302. Multiple locking holes are machined circumferentially on the bottom of the groove. A second through hole is machined at the end of the planar square frame structure 303, and the long side and the arc-shaped edge 302 are locked together by a bolt. An elastic washer is placed on the inner side of the long side to fit the aforementioned groove; in this way, the bolt passes through the long side and then through the elastic washer to increase the locking stability and avoid the bolt falling off due to vibration during the drilling process.

[0055] The movable drill rig is equipped with a linear motion mechanism and an electric drill; optional, such as Figure 5 As shown, the linear motion mechanism in this embodiment is a linear motor 201, which includes a guide rail and a slider.

[0056] The guide rail of the linear motor 201 is the fixed end of the movable drill rig 2 and is mounted on the planar square frame structure 303 by screws.

[0057] The slider of the linear motor 201 is the movable end of the movable drill 2 and is fixedly connected to the fixed end of the electric drill 204.

[0058] Furthermore, to enable adjustable mounting position of the electric drill 204, this embodiment includes a bracket 202 between the movable end of the linear motion mechanism and the fixed end of the electric drill. In this embodiment, the bracket 202 is a ribbed bracket, with its base plate fixedly connected to the slider of the linear motor 201. The upper part of the bracket 202 is an arc-shaped support plate with a contoured arc surface adapted to the electric drill, and is detachably connected to the main body of the electric drill 204 via two semi-circular metal clamps 203.

[0059] Optionally, the electric drill 204 is a bench drill with a drill chuck at the front end for detachable installation of the drill bit 205.

[0060] Working principle;

[0061] In practical application, this embodiment first disassembles the brake housing 4. Based on the size, structure, and improvement requirements of the brake housing 4, a corresponding top claw 104 is selected and secured. The turntable 101 is adjusted to align the opening position with the location of the electric drill 204. Given that the opening position has certain vertical requirements, a suitable bracket 202 is selected, and the electric drill 204 is fixed using a semi-circular metal clamp 203. Then, the linear motor 201 and the electric drill 204 are started, and the opening / tapping process is performed according to the program design. The reason for selecting the fixed-structure bracket 202 is that the vertical position requirement for openings is generally not high. Adding a height-adjustable structure to the bracket 202 would increase the cost of the device, and vibration resistance and strength issues must also be considered. The height issue (vertical position) can be solved to some extent by fixing the position with the top claw; therefore, the above structure is preferred after comprehensive consideration. Furthermore, when the opening or tapping position has an angle, then... Figure 6 As shown, the pitch angle of the movable drill 2 can be adjusted by changing different locking holes. Similarly, since the machining position accuracy requirement is not high, there is no need to design a stepless adjustment structure. Changing the pitch angle is mainly to make the drill bit 205 as perpendicular to the machining surface as possible, to avoid damage to the drill bit 205, and to make the machined hole nearly perpendicular to the inner surface of the housing, which can reduce the hole resistance and facilitate air venting and chip removal.

[0062] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
