Description

Technical Field

[0001] This invention relates to the field of marine engine technology, and in particular to a main engine piston rod fixing fixture. Background Technology

[0002] The main engine, or marine propulsion unit, is the machinery that provides power to various types of ships, and the piston rod of the main engine is an essential component for power transmission.

[0003] Currently, the handling of the main piston rod is mainly carried out using forklifts and hoists. However, due to the considerable height of the main piston rod (some pistons are 3 meters or even taller depending on the model), it sways back and forth and side to side during transport, causing dents when it collides with the edge of the piston barrel or the forklift mast. This seriously affects product quality and may even lead to compensation disputes. Therefore, how to secure the main piston rod after hoisting it into the piston barrel is a major challenge. Previously, the main piston was secured using a (top-press binding) method, which resulted in poor stability. During transport, the binding straps often came loose, creating safety hazards. Therefore, this application provides a main piston rod securing fixture to meet the requirements. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a main unit piston rod fixing fixture, which solves the problems that existing main unit piston rods often become loose during transportation, have poor stability, easily cause safety hazards, and damage the main unit piston rod, affecting product quality.

[0009] The clamping assembly includes a housing, a telescopic rod, a clamp, a rubber sheet, a handle, a lead screw, and a mounting base. The telescopic rod is sleeved on the front end of the housing, and a clamp is welded to the front end of the telescopic rod. A rubber sheet is pasted on the inner side of the clamp. A handle is threaded on the rear side of the housing, and a lead screw is threaded on the inner side of the housing. A mounting base is welded to the lower part of the outer end of the housing.

[0010] Preferably, the buffer assembly includes an inner panel, a reinforcing block, a retaining block, a pull rod, and a mesh tray. The reinforcing block is welded to the middle of the inner side of the inner panel, the retaining block is welded to the middle of the inner side of the reinforcing block, the pull rod is retaining the inner side of the retaining block, and the mesh tray is retaining the lower inner side of the pull rod.

[0011] Preferably, the stabilizing component includes an adjusting column, a throttle, a sleeve, and an arc-shaped block. The throttle is threaded onto the rear end of the adjusting column, the sleeve is threaded onto the front end of the adjusting column, and the arc-shaped block is welded onto the front end of the sleeve.

[0012] Preferably, the reinforcement assembly includes a reinforcement chassis, a bottom retaining ring, a rubber ring, an angle iron, a lower anti-collision block, a pressure disc, an upper anti-collision block, and a rubber disc. The bottom retaining ring is welded to the upper end of the reinforcement chassis. A rubber ring is sleeved below the outer end of the bottom retaining ring. An angle iron is welded to the outer end of the bottom retaining ring. The lower anti-collision block is threaded onto the bottom of the inner side of the bottom retaining ring. A pressure disc is sleeved onto the inner side of the bottom retaining ring. An upper anti-collision block is welded to the outer side of the lower end of the pressure disc. A rubber disc is embedded in the middle of the inner side of the pressure disc.

[0013] Preferably, the lifting assembly includes a threaded rod, an upper nut, a lower nut, a support spring, and a bottom nut. The upper nut is threaded onto the upper part of the outer end of the threaded rod, the lower nut is threaded onto the lower part of the upper nut, the support spring is sleeved onto the lower part of the lower nut, and the bottom nut is threaded onto the lower part of the support spring.

[0014] Preferably, there are two symmetrically distributed support legs, the support legs are L-shaped, the pedal box is made of two welded together at different heights, and there are two symmetrically distributed piston cylinders.

[0015] Preferably, the rear end of the telescopic rod extends into the interior of the housing, the clamp consists of two parts, the front part is detachable, and the rear part is welded to the telescopic rod to form an integral structure, the front end of the lead screw extends into the interior of the telescopic rod and is threadedly connected to each other, and the lead screw is threadedly connected to the housing.

[0016] Preferably, the inner panel has eight symmetrically distributed pieces, the front and rear ends of the pull rod are provided with insertion holes, the outer side of the upper end of the mesh tray is welded with eight locking blocks, the upper end of the locking blocks is provided with locking grooves, and the mesh tray is formed by welding an outer ring and a steel mesh.

[0017] Preferably, there are four symmetrically distributed adjusting columns. The sleeve has a hollow structure inside, and an inner diameter thread is provided inside the hollow structure. The front end of the adjusting column extends into the inside of the inner diameter thread, and the two are compatible.

[0018] Preferably, a support spring is sleeved on the upper end of the lower anti-collision block, and an adapter groove is provided inside the upper anti-collision block, which is adapted to the upper end of the lower anti-collision block.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above solution, the handle is used to rotate the lead screw inside the housing, pushing the telescopic rod at the front end to extend forward to the center area above the piston cylinder. The main piston rod is reinforced with a clamp to prevent the upper structure of the main piston rod from colliding with the upper structure inside the piston cylinder during transportation, thus reducing the probability of damage.

[0021] The embedded plates, reinforcing blocks, and retaining blocks are integrated to form a panel structure, which consists of eight symmetrically distributed panels. These panels are secured to the inner wall of the piston cylinder with screws. The mesh tray is connected by a pull rod design to support the bottom of the main piston rod. When the main piston rod is hoisted into the piston cylinder, the downward impact force is reduced, ensuring that the bottom of the main piston rod does not collide with the bottom of the piston cylinder and cause damage.

[0022] The throttle handle allows for manual rotation, causing the adjusting column at the front end to rotate inward along the threaded groove at the contact end with the piston cylinder. As displacement occurs, the sleeve also moves inward synchronously. Since the sleeve and the arc-shaped block are symmetrically distributed, the arc-shaped block clamps and supports the main piston rod from all four sides, improving the stability of the main piston rod during transport.

[0023] In summary, this invention provides comprehensive protection for the internal main piston rod through the function of three different component structures. This allows operators to easily and safely securely fix the main piston rod during transportation, increasing the operability of binding and fixing, preventing accidents, improving product quality, and avoiding unnecessary compensation disputes.

[0040] like Figures 1-7 As shown, an embodiment of the present invention provides a main piston rod fixing fixture, including a mounting plate 1. Support legs 2 are bolted to the lower end of the mounting plate 1. Two support legs 2 are symmetrically distributed and are L-shaped for easy forklift handling. A footrest box 3 is welded to the middle of the rear side of the upper end of the mounting plate 1. The footrest box 3 consists of two welded pieces of varying heights, allowing for stepping on and reinforcing the main piston rod when handling a large main piston rod. A reinforcing component 4 is screwed to the front side of the upper end of the mounting plate 1. A central stabilizing ring 5 is sleeved on the upper part of the reinforcing component 4. A lifting component 6 is threaded on the inner side of the upper end of the central stabilizing ring 5. Two piston cylinders 7 are symmetrically distributed. Hooks are welded to the contact end between the outer wall of the piston cylinder 7 and the mounting base 907. The hooks are longitudinally symmetrically distributed to allow for subsequent adjustment of the vertical height of the clamping component 9 mounting structure. A buffer component 8 is provided inside the piston cylinder 7, and a clamping component is installed at the front side of the outer end of the piston cylinder 7. The piston cylinder 7 has a clamping assembly 9, and a stabilizing assembly 10 is threaded onto the outer end of the piston cylinder 7. The clamping assembly 9 includes a housing 901, a telescopic rod 902, a clamp 903, a rubber sheet 904, a handle 905, a lead screw 906, and a mounting base 907. The telescopic rod 902 is sleeved onto the front end of the housing 901, and the rear end of the telescopic rod 902 extends into the interior of the housing 901. The clamp 903 is welded to the front end of the telescopic rod 902. The clamp 903 consists of two parts, the front part is detachable, and the rear part is attached to the telescopic rod 901. The telescopic rod 902 is welded into a single structure. A rubber sheet 904 is attached to the inner side of the clamp 903. A handle 905 is threaded onto the rear side of the outer shell 901. A lead screw 906 is threaded onto the inner side of the outer shell 901. The front end of the lead screw 906 extends into the interior of the telescopic rod 902 and is threaded together with the other two. The lead screw 906 is threaded onto the outer shell 901. A mounting seat 907 is welded onto the lower outer end of the outer shell 901. The mounting seat 907 is clamped onto the outer wall structure of the piston cylinder 7.

[0041] The handle 905 drives the lead screw 906 to rotate inside the housing 901, pushing the telescopic rod 902 at the front end to extend forward to the center area above the piston cylinder 7. The clamp 903 is used to reinforce the main piston rod, so that the upper structure of the main piston rod will not collide with the upper structure inside the piston cylinder 7 during transportation, reducing the probability of damage.

[0042] The mounting height of the clamping assembly 9 can be adjusted by using the mounting base 907, which is positioned to hold the hooks on the outer wall of the piston cylinder 7.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the buffer assembly 8 includes an inner panel 801, a reinforcing block 802, a retaining block 803, a pull rod 804, and a mesh tray 805. Eight inner panels 801 are symmetrically distributed. A reinforcing block 802 is welded to the center of the inner side of each inner panel 801. A retaining block 803 is welded to the center of the inner side of each reinforcing block 802. A pull rod 804 is retained on the inner side of the retaining block 803. Insertion holes are provided at both the front and rear ends of the pull rod 804. A mesh tray 805 is retained on the lower inner side of the pull rod 804. The mesh tray 805 is formed by welding an outer ring to a steel mesh. Furthermore, the mesh tray 805... Eight locking blocks are welded to the outer side of the end, and the upper end of the locking blocks is provided with a locking groove; the stabilizing component 10 includes an adjusting column 1001, a throttle 1002, a sleeve 1003 and an arc block 1004. There are four symmetrically distributed adjusting columns 1001. The throttle 1002 is threadedly installed at the rear end of the adjusting column 1001, and the sleeve 1003 is threadedly installed at the front end of the adjusting column 1001. The sleeve 1003 has a hollow structure inside, and an inner diameter thread is provided inside the hollow structure. Furthermore, the front end of the adjusting column 1001 extends into the interior of the inner diameter thread, and the two are compatible. The arc block 1004 is welded to the front end of the sleeve 1003.

[0044] The embedded plate 801, reinforcing block 802, and retaining block 803 are integrated to form a plate structure, and eight plates are symmetrically distributed. They are reinforced to the inner wall of the piston cylinder 7 by screws. The mesh tray 805 is connected by the design of the pull rod 804 to support the bottom of the main piston rod. When the main piston rod is hoisted into the piston cylinder 7, the downward impact force is reduced to ensure that the bottom of the main piston rod does not collide with the bottom of the piston cylinder 7 and cause damage.

[0045] The throttle 1002 can be manually rotated, causing the adjusting column 1001 at the front end to rotate inward along the threaded groove at the contact end with the piston cylinder 7. As displacement occurs, the sleeve 1003 is also moved inward synchronously. Since the sleeve 1003 and the arc-shaped block 1004 are symmetrically distributed, the arc-shaped block 1004 clamps and supports the main piston rod on all four sides, improving the stability of the main piston rod under the main piston rod during transportation.

[0046] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the reinforcement component 4 includes a reinforcement chassis 401, a bottom retaining ring 402, a rubber ring 403, an angle iron 404, a lower anti-collision block 405, a pressure disc 406, an upper anti-collision block 407, and a rubber disc 408. A bottom retaining ring 402 is welded to the upper end of the reinforcement chassis 401. A rubber ring 403 is sleeved below the outer end of the bottom retaining ring 402. An angle iron 404 is welded to the outer end of the bottom retaining ring 402. A lower anti-collision block 405 is threaded onto the bottom of the inner side of the bottom retaining ring 402. A spring is sleeved onto the upper end of the lower anti-collision block 405. A pressure disc 406 is sleeved onto the inner side of the bottom retaining ring 402. An upper anti-collision block 407 is welded and installed on the outer side of the lower end of the disc 406. The upper anti-collision block 407 has an adapter groove inside, and the adapter groove is adapted to the upper end of the lower anti-collision block 405. A rubber disc 408 is embedded and installed in the middle of the inner side of the pressing disc 406. The lifting assembly 6 includes a threaded rod 601, an upper nut 602, a lower nut 603, a support spring 604, and a bottom nut 605. The upper nut 602 is threaded on the upper part of the outer end of the threaded rod 601, the lower nut 603 is threaded on the lower part of the upper nut 602, the support spring 604 is sleeved on the lower part of the lower nut 603, and the bottom nut 605 is threaded on the lower part of the support spring 604.

[0047] By designing the rubber disc 408 to be positioned below the mesh tray 805, when the steel wire inside the mesh tray 805 breaks, the main piston rod contacts the rubber disc 408, causing the pressure disc 406 to move downwards, allowing the lower anti-collision block 405 and the upper anti-collision block 407 to move up and down. The sleeve spring generates buffering, reducing the buffering force and preventing damage to the bottom structure of the main piston rod, thus providing further protection.

[0048] The design of the bottom retaining ring 402 and the central stabilizing ring 5 provides clamping protection on the outside of the piston cylinder 7. Furthermore, the threaded rod 601 allows adjustment of the distance between the central stabilizing ring 5 and the bottom retaining ring 402, thereby adjusting the height of the protective center of gravity of the piston cylinder 7. In the event of an accident involving a transport vehicle, the piston cylinder 7 can remain stably positioned at the upper end of the mounting plate 1, preventing breakage or detachment at the welded joint and thus improving the safety of the main piston rod tooling.

[0049] The technical solution provided by this invention is as follows: A handle 905 drives a lead screw 906 to rotate inside the housing 901, pushing the telescopic rod 902 forward to the center area above the piston cylinder 7. A clamp 903 reinforces the upper structure of the main piston rod, preventing collisions between the upper structure and the upper structure inside the piston cylinder 7 during transport. The middle structure can be manually rotated via a handle 1002, causing the adjusting column 1001 to rotate inward along the threaded groove at the contact end with the piston cylinder 7. Simultaneously, the sleeve 1003 moves inward synchronously. Since the sleeve 1003 and the arc-shaped block 1004 are symmetrically distributed, the arc-shaped block 1004 clamps and supports the placed main piston rod from all four sides. The lower structure, through the design of the rubber disc 408, is positioned below the mesh tray 805. When the steel wire inside the mesh tray 805 breaks, the main piston rod contacts the rubber disc 408, causing the pressure disc 406 to move downwards. This allows the lower anti-collision block 405 and the upper anti-collision block 407 to move up and down, with the sleeve spring providing cushioning to reduce the buffering force and prevent damage to the bottom structure of the main piston rod, thus providing further protection. This main piston rod fixing fixture, through the action of three different component structures, provides all-round protection for the internally placed main piston rod. During transportation, it not only allows operators to easily and safely fix the main piston rod, increasing the operability of binding and fixing, but also avoids accidents, improves product quality, and avoids unnecessary compensation disputes.
