Description

Technical Field

[0001] This utility model relates to the field of marine engineering, specifically a device that converts the low-torque, high-speed rotational motion of an electric wrench into a high-torque, low-speed force-increasing and deceleration device, which can change the traditional manual release and retraction method of a ratchet wrench to electric release and retraction using an electric wrench. Background Technology

[0002] The bow flagpole of a ship needs to be raised or lowered frequently due to varying ship conditions. This operation is typically performed manually using a ratchet wrench, which is inefficient and physically demanding. Furthermore, ratchet wrenches are prone to damage from sudden, large forces or bending of the flagpole due to the sudden force applied manually. To address these challenges of low efficiency, high intensity, and frequent malfunctions associated with manual bow flagpole operation, this bow flagpole booster and speed reducer tool was designed. With the assistance of ordinary power tools, the bow flagpole can be raised and lowered quickly. Utility Model Content

[0003] The purpose of this application is to provide a force-boosting tool to solve the problems of slow raising and lowering of existing ship bow flagpoles and easy damage to ratchet wrenches. A force-boosting and speed-reducing device is provided to convert the manual raising and lowering of the ship bow flagpole ratchet wrench to an electric raising and lowering device using an electric wrench. This device includes a connecting flange 1, an operating handle 2, a housing 3, a front cover 4, an input shaft 5, a support bearing 6, and an output shaft 10.

[0004] The housing 3 contains a primary reducer 7, a secondary reducer 8, and an input shaft gear 9. The input shaft 5, the primary reducer 7, and the secondary reducer 8 are connected by gears within the support bearing 6.

[0005] Furthermore, the first-stage reducer 7 includes a first-stage output gear 71, a first-stage planetary carrier 72, a first-stage planetary gear 73, and a first-stage auxiliary carrier 74. The first-stage planetary gear 73 is mounted on the first-stage locating pin 76 of the first-stage planetary carrier 72 and is fixed to the first-stage planetary carrier 72 by the first-stage auxiliary carrier 74 and the first-stage fixing screw 75.

[0006] Furthermore, the secondary reducer 8 includes an output shaft 10, an output shaft square hole 81, a secondary planetary carrier 85, a secondary planetary gear 83, and a secondary auxiliary carrier 84. The secondary planetary gear 83 is mounted on the secondary locating pin 82 of the secondary planetary carrier 85 and is fixed to the secondary planetary carrier 85 by the secondary auxiliary carrier 84 and the secondary fixing screw 86.

[0007] The beneficial effects of this utility model are: by using this power boosting and deceleration device, it can be quickly matched to the input shaft of the flagpole gearbox, connecting the power tool and the input shaft of the power boosting and deceleration device together. This can conveniently convert the low torque, high speed rotational motion of the power tool into high torque, low speed rotational motion, which is then applied to the input shaft of the flagpole gearbox to realize the raising and lowering operation of the flagpole.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 The diagram shows the external shape of the force-boosting and deceleration device. On the left side of the force-boosting tool is a connecting flange 1 that connects to the input shaft of the gearbox. When the tool is in use, this flange fits against the gearbox flange, and the head of the hexagonal bolt on the gearbox flange is inserted into the flange hole of the flange to provide support. When the force-boosting tool generates torque, this flange provides torque support.

[0015] Figure 2 Exploded view of the bow flagpole gearbox power-up tool. Figure 2The connecting flange 1 and the outer casing 3 are connected by welding, and in practice, they are a single unit. The front cover 4 is installed inside the outer casing 3 and fixed with a snap ring. The input shaft 5 is mounted on the center hole of the support bearing 6 and positioned by an elastic retaining ring. The support bearing 6 is installed in the center hole of the front cover 4. The output shaft 10 is milled from the second-stage planetary carrier 85 of the two-stage reducer 8.

[0016] Figure 3 This is a structural diagram of the first-stage reducer 7, which consists of a first-stage output gear 71, a first-stage planetary carrier 72, a first-stage planetary gear 73, a first-stage locating pin 76, a first-stage fixing screw 75, and a first-stage auxiliary frame 74. During operation, the input shaft gear 9 drives the first-stage planetary gear 73, which, supported by the internal gear ring, causes the first-stage planetary carrier 72 to rotate. Power is then output through the first-stage output gear 71 and transmitted to the second-stage reducer.

[0017] Figure 4 This is a structural diagram of the two-stage reducer 8, which consists of an output shaft 10, a two-stage planetary carrier 85, a two-stage planetary gear 83, a two-stage locating pin 82, a two-stage fixing screw 86, and a two-stage auxiliary frame 84. During operation, the first-stage output gear 71 drives the second-stage planetary gear 83, which, supported by the internal gear ring, causes the second-stage planetary carrier 85 to rotate. Power is output through the output shaft 10, and the square hole 81 of the output shaft is clearance-fitted with the input shaft of the bow flagpole gearbox, driving its rotation.

[0018] Thus, by using a power tool to drive the input shaft gear of the torque-increasing and decelerating device, the power after torque amplification and deceleration is transmitted to the input shaft of the bow flagpole gearbox through a two-stage reducer, thereby driving the bow flagpole raising and lowering operation.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
