[0001] This invention belongs to the field of marine vessel design and construction, and specifically relates to a pneumatic brake shaft locking integrated machine for ship shafting. Background Technology

[0002] Twin-shaft vessels are typically equipped with braking and shaft locking systems. These are usually two independent devices that operate separately, but the engine room space is usually quite narrow, which increases the difficulty of arranging the equipment.

[0003] This patent discloses an integrated pneumatic brake shaft locking device for ship shafting, which saves engine room space, solves the problem of engine room equipment layout, and reduces the failure rate of the equipment. Summary of the Invention

[0004] To solve the above problems, the present invention provides a pneumatic brake and shaft locking integrated machine for ship shafting, the technical solution of which is as follows:

[0005] A pneumatic brake and shaft locking integrated machine for ship shafting has a box-shaped main body with an open front side.

[0006] Two friction discs are fixed side by side inside the box-shaped body, with a gap between them. A brake hydraulic cylinder is fixed between the friction discs and the box-shaped body. One side of the brake hydraulic cylinder is fixed to the friction disc, and the other side is fixed to the box-shaped body by bolts.

[0007] Each of the two sides of the box-shaped main body is fixed with a locking hydraulic cylinder. The locking hydraulic cylinder has a locking pin. The locking pins of the two locking hydraulic cylinders penetrate the box-shaped main body and are connected inside the box-shaped main body. The locking hydraulic cylinder is connected to a central processing unit. One of the central processing units is fixed with a locking sensor. The locking hydraulic cylinder has a release air hole and a locking air hole.

[0008] A brake sensor, a brake position sensor, and a brake lock shaft linkage sensor are fixed on the top outer surface of the box-shaped main body. Brake air inlets and brake exhaust ports are provided on the outer surfaces of both sides of the box-shaped main body.

Detailed Implementation

[0019] The invention will be further described with reference to the accompanying drawings.

[0020] A pneumatic brake and shaft locking integrated machine for ship shafting, such as Figure 1 , 2 As shown in Figure 3, there is a box-shaped main body with the front side of the box-shaped main body open.

[0021] Two friction discs are fixed side-by-side inside the box-shaped main body, with a gap between them. A brake hydraulic cylinder is fixed between the friction discs and the box-shaped main body; one side of the brake hydraulic cylinder is fixed to the friction disc, and the other side is fixed to the box-shaped main body with bolts. The extension and retraction of the friction discs are adjusted by the input and output of external compressed air. When compressed air is introduced, the hydraulic cylinder extends, and the two friction discs move towards the center to clamp the shaft flange, achieving the shaft braking function; when compressed air is exhausted, the hydraulic cylinder retracts, and the two friction discs move to the sides to release the shaft flange, thus releasing the brake. The braking function is achieved by controlling the gap between the two friction discs through friction between the friction discs and the shaft flange; the friction discs are only connected to the hydraulic cylinder.

[0022] Two locking hydraulic cylinders are fixed to the exterior of the box-type main body on each side. Each locking cylinder has a locking pin, and the locking pins of the two cylinders penetrate the box-type main body and connect internally. The locking pins are connected to the locking hydraulic cylinders, and their actual positions are controlled by the cylinders. Different positions determine whether the locking function is achieved. In the locked position, the shaft system is locked; in the disengaged position, the shaft system can rotate freely. The locking pins can move back and forth and are externally connected to the input and output of compressed air. The position of the locking pins is controlled by the input and output of external compressed air, and different positions achieve different functions. The locking hydraulic cylinders are connected to a central processing unit, one of which has a locking sensor fixed on it. One side of the locking sensor detects the position of the locking pin and outputs a signal, while the other side is connected to the central processing unit. If a signal is output to the central processing unit, it indicates that the shaft system is in a locked state, and the main engine and turning gear are not allowed to operate; if no signal is output, it indicates that the shaft system is in a disengaged state, and the main engine and turning gear can operate. The locking hydraulic cylinders have disengagement air holes and locking air holes. The locking vent is connected to the air intake pipe, and the locking pin is in the locked position when air is intake; the disengaging vent is connected to the air intake pipe, and the locking pin is in the disengaged position when air is intake.

[0023] The outer surfaces of both sides of the box-shaped main body are equipped with brake air inlets and brake air outlets. External compressed air enters through the brake air inlets, enabling the brake hydraulic cylinder to expand. The brake air inlets are located on the main body and have a thread size of G1 / 2. One side connects to the internal hydraulic cylinder, and the other side connects to the external air intake and exhaust system. The brake air outlets expel air from the hydraulic cylinder, enabling the brake hydraulic cylinder to contract. The brake air outlets are also located on the main body and have a thread size of G1 / 2. One side connects to the internal hydraulic cylinder, and the other side connects to the external air intake and exhaust system.

[0024] A brake sensor, a brake position sensor, and a brake lock shaft linkage sensor are fixed to the top outer surface of the box-type main body. The brake sensor is located on the main body and generates a signal by detecting the distance between the friction discs. If the distance between the two friction discs is equal to the thickness of the shaft flange, a signal is output; otherwise, no signal is output. The brake sensor is connected to the central processing unit (CPU) via a cable. If a signal is output, it indicates that the shaft system is in a braking state, and the main engine and turning gear are not allowed to operate; if no signal is output, it indicates that the shaft system is in a released braking state, and the main engine and turning gear can operate. One end of the brake position sensor detects the distance from the groove position of the shaft flange to the locking pin, and the other end is connected to the CPU, providing the CPU with the specific position of the flange. The CPU adjusts the braking force according to the flange position, stopping the flange groove position at the position where the locking pin can operate. One end of the brake lock shaft linkage sensor is connected to the central processing unit, and the other end is connected to the brake system. When the brake system is working and the grooved position of the shaft flange stops at the working position of the locking pin, the brake lock shaft linkage sensor determines which signal to output to the central processing unit by judging the position of the locking pin. The central processing unit analyzes and processes the signal content and outputs a signal to the lock shaft sensor to notify that the locking operation can be performed.

[0025] This invention, by designing an integrated pneumatic brake and shaft locking device for ship shafting, fills a gap in the field of ship shafting equipment, achieving a breakthrough in integrating braking and shaft locking functions into one device, reducing ship equipment procurement costs, and saving engine room layout space.
