Description

Technical Field

[0001] The utility model relates to the technical field of a lightweight lock shaft rocker arm structure, in particular to a lightweight lock shaft rocker arm structure. Background Technique

[0002] When a ship is in a powerless state, the shafting of the rudder and propeller device is also in a powerless state. Without a braking device, the main power shafting of the ship will rotate due to the action of wind and waves and water flow. This braking device should effectively lock the shafting when the ship is stationary, and the rotation of the ship's shafting can be effectively and reliably disengaged.

[0003] At present, there are two types of lock shaft devices actually applied to ships, namely a brake disc type lock shaft device and a non-brake disc type lock shaft device. The brake disc type lock shaft device is further divided into a disc type lock shaft device and a pin type lock shaft device.

[0004] Among them, the brake disc type lock shaft device is relatively complex in processing and manufacturing, has a high cost, occupies a large space during installation, is inconvenient to use and install, and it is not easy to output the working state signal of the lock shaft device; while the non-brake disc type lock shaft device, such as the propeller flange lock shaft device, is not applicable to the full-rotation rudder and propeller device.

[0005] To solve the above problems, we propose a lightweight lock shaft rocker arm structure to solve the above problems. Content of the Utility Model

[0006] To solve the problems in the background technique, the utility model provides a lightweight lock shaft rocker arm structure. The lightweight rocker arm is fixed on the structural body of the rudder and propeller device. The lock shaft function utilizes the existing brake disc. The lock shaft pin is inserted into the uniformly distributed locking pin holes on the brake disc to realize the lock shaft function. At the same time, the fixing pin is inserted into the fixing hole of the structural body to fix the rocker arm in two working positions (corresponding to the release state or the lock shaft state respectively), and trigger the lock shaft induction component, so as to give the signal output of the two states and ensure the safety of the equipment during operation.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A lightweight lock shaft rocker arm structure includes a structural body, a brake disc and a brake. The side end of the structural body is movably connected with a rocker arm. The rocker arm is located in the middle of the side end of the brake disc. A lock shaft pin is arranged at the head end of the rocker arm. Multiple groups of locking pin holes are arranged on the upper surface of the brake disc. The multiple groups of locking pin holes are annularly arrayed with the center point of the brake disc, and are close to the edge of the upper surface of the brake disc. The lock shaft pin is inserted into the locking pin hole to limit and fix the brake disc.

[0009] Preferably, a fixing component is provided at the bottom of the rocker arm. The fixing component includes a fixing pin. By inserting the fixing pin into the fixing hole at the corresponding position of the structure body, the rocker arm is limited and fixed.

[0010] Preferably, an installation cylinder is installed on the upper side of the bottom end of the rocker arm. The fixing pin is slidably installed in the middle of the inner side of the installation cylinder. A limiting rod is provided in the middle of the bottom end of the fixing pin. Two groups of clamping grooves are provided at the bottom end of the installation cylinder. By clamping the limiting rod in the middle of the inner side of the clamping groove, the fixing pin is limited and fixed.

[0011] Preferably, a safety bolt is further provided on the outer side of the installation cylinder. The safety bolt is used to limit the limiting rod.

[0012] Preferably, a rotating shaft is provided at the bottom end of the rocker arm. The rotating shaft is movably connected to the structure body through a fixing member.

[0013] Preferably, shear-resistant plates are provided on both sides of the bottom end of the rocker arm.

[0014] Preferably, a lock shaft induction component is provided at the side end of the structure body, including a locking state inductor and a release state inductor.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In this solution, by providing a rocker arm, the rocker arm integrates a lock shaft pin, and a fixing component is provided at the bottom of the rocker arm, thereby improving the stability in the lock shaft state or the release state. Specifically, a lock shaft pin is provided at the head end of the rocker arm. The lock shaft function is realized by inserting the lock shaft pin into the uniformly distributed locking pin holes on the brake disc. At the same time, the fixing pin is inserted into the corresponding fixing hole of the structure body to fix the rocker arm at two working positions (corresponding to the release state or the lock shaft state respectively), and trigger the lock shaft induction component, thereby giving a signal output of two states to ensure the safety of the equipment during operation.

Specific implementation mode

[0022] An embodiment of the present application proposes a lightweight locking shaft rocker arm structure, specifically by arranging a locking shaft pin 31 at the head end of the rocker arm 3, and realizing the locking shaft function by inserting the locking shaft pin 31 into the uniformly distributed locking pin holes 21 on the brake disc 2; at the same time, inserting the fixing pin 5 into the corresponding fixing holes of the structural body 1 to fix the rocker arm 3 at two working positions (corresponding to the release state or the locking shaft state respectively), and triggering the locking shaft induction component, so as to give signal outputs of two states and ensure the safety of the equipment during operation.

[0023] Embodiment: Refer to Figure 1 - Figure 4 As shown, a lightweight locking shaft rocker arm structure of this embodiment includes a structural body 1, a brake disc 2 and a brake 9. The side end of the structural body 1 is movably connected with a rocker arm 3. The rocker arm 3 is located in the middle of the side end of the brake disc 2. A locking shaft pin 31 is arranged at the head end of the rocker arm 3. Multiple groups of locking pin holes 21 are arranged on the upper surface of the brake disc 2. The multiple groups of locking pin holes 21 are annularly arrayed with the center point of the brake disc 2 and are close to the edge of the upper surface of the brake disc 2.

[0024] Among them, by inserting the locking shaft pin 31 into the locking pin hole 21, the brake disc 2 is limited and fixed.

[0025] In addition, a fixing component is arranged at the bottom of the rocker arm 3. The fixing component includes a fixing pin 5. By inserting the fixing pin 5 into the fixing hole at the corresponding position of the structural body 1, the rocker arm 3 is limited and fixed, thereby improving the stability of the locking shaft.

[0026] An installation cylinder 4 is installed on the upper side of the bottom end of the rocker arm 3. The fixing pin 5 is slidably installed in the middle of the inner side of the installation cylinder 4. A limiting rod 51 is arranged in the middle of the bottom end of the fixing pin 5. Two groups of card slots 41 are arranged at the bottom end of the installation cylinder 4. By clamping the limiting rod 51 in the middle of the inner side of the card slot 41, the fixing pin 5 is limited and fixed; a safety bolt 6 is also arranged on the outer side of the installation cylinder 4, and the safety bolt 6 is used to limit the limiting rod 51.

[0027] Among them, by clamping the limiting rod 51 into the corresponding card slot 41 and then installing the safety bolt 6, the limiting and fixing of the fixing pin 5 is realized. By limiting and fixing the fixing pin 5, the stability of the shape of the rocker arm 3 is further improved, and the vibration generated during the operation of the rudder and propeller device is avoided, so as to prevent the rocker arm 3 from shaking, and thus the situation that the locking shaft pin 31 jumps off and causes equipment damage is prevented.

[0028] A rotating shaft 32 is arranged at the bottom end of the rocker arm 3. The rotating shaft 32 is movably connected to the structural body 1 through a fixing member. The arrangement of the rotating shaft 32 facilitates the rotation of the rocker arm 3.

[0029] In some examples, shear-resistant plates 33 are arranged on both sides of the bottom end of the rocker arm 3, which can offset the bending moment generated by the locking shaft shear force, so that the cross-sections of the rotating shaft 32 and the rocker arm 3 body can be reduced, thereby realizing a lightweight structure.

[0030] In some examples, a locking shaft induction component is arranged at the side end of the structural body 1, including a locking state inductor 7 and a release state inductor 8.

[0031] The working principle of the present utility model is as follows:

[0032] When the brake disc 2 needs to be locked on the shaft, first rotate the rocker arm 3 so that the rocker arm 3 rotates around the rotating shaft 32, thereby realizing the rotation of the rocker arm 3 close to the upper surface of the brake disc 2, so as to facilitate the insertion of the locking shaft pin 31 into the locking pin hole 21 on the brake disc 2 to realize the locking and fixing of the brake disc 2. This is the shaft locking state;

[0033] Moreover, by pulling the limiting rod 51 to drive the fixing pin 5 to slide in the installation cylinder 4, when the fixing pin 5 slides to the right, the end of the fixing pin 5 can be inserted into the hole opened at the side end of the structural body 1, and then the limiting rod 51 is rotated to clamp the limiting rod 51 into the card slot 41 on the right side of the bottom of the installation cylinder 4, and the limiting rod 51 is limited by installing the safety bolt 6 to prevent the limiting rod 51 from falling off the card slot 41, further improving the stability of the fixing pin 5 inserted into the structural body 1, and thus further strengthening the function of limiting and fixing the rocker arm 3.

[0034] Conversely, when it is necessary to release the locking shaft, only the safety bolt 6 needs to be disassembled, and then the fixed pin 5 can be pulled by the limit rod 51 to release the limit on the fixed pin 5, so as to facilitate the lifting of the rocker arm 3, causing the separation between the locking shaft pin 31 and the locking pin hole 21. Then, continue to rotate the rocker arm 3 until it reaches the end position. At this time, the fixed pin 5 can be slid to the left so that the fixed pin 5 is inserted into the corresponding hole opened on the left side of the structural body 1. Then, rotate the limit rod 51 so that the limit rod 51 is clamped in the card slot 41 on the left side of the bottom of the mounting cylinder 4. Then, install the safety bolt 6 again to limit and fix the positions of the limit rod 51 and the fixed pin 5, and then limit and fix the position of the rocker arm 3. At this time, the rocker arm 3 and the brake disc 2 are in a nearly vertical structure, which is the release state.

[0035] In addition, by providing a locking state sensor 7 and a release state sensor 8, the state of whether the shaft is locked can be detected, and thus signal outputs of two states can be given.

[0036] In some examples, the fixed pin 5 is designed with a sufficient extended length so that it can trigger the corresponding sensors in both the locked state and the released state, achieving an accurate indication of the locked state of the operating system.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
