Description

Technical Field

[0001] This utility model relates to the field of ship lifting equipment technology, specifically a self-locking parking device for a marine monorail crane. Background Technology

[0002] Marine monorail cranes, as a type of lifting equipment widely used in the shipbuilding industry, play a crucial role in the entire ship cargo lifting operation. They are mainly composed of two core parts: rails and lifting devices. The rails are generally made of high-strength steel and are usually installed on the top or side walls of the ship's cabins. The design and installation of these rails must be strictly based on the ship's structural characteristics and actual usage requirements to ensure that they can stably and reliably bear the weight of the lifting devices and cargo.

[0003] The monorail gantry plays a crucial role in the cargo handling process of ships, playing an irreplaceable role in a series of operations such as loading and unloading cargo and transferring cargo between different areas of the ship. Whether it is loading and unloading cargo when the ship is in port or transferring cargo between different compartments during the ship's voyage, the marine monorail gantry is an indispensable and important piece of equipment.

[0004] However, existing marine monorail crane parking devices typically rely on parking pins to secure the crane to the parking platform when not in operation. This design poses certain safety hazards. Due to the complex and changeable marine environment, ships may experience strong vibrations and swaying, which could cause the parking pins to loosen, resulting in the monorail crane losing its fixation and even falling into the sea. This could not only damage the monorail crane itself but also lead to serious consequences such as cargo damage and personal injury. Therefore, a self-locking parking device for marine monorail cranes is proposed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a self-locking parking device for a marine monorail crane, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a self-locking parking device for a marine monorail crane, which is set on the upper end of a moving crossbeam. A track beam is set above the moving crossbeam. A locking hole is opened on the side of the track beam. A parking plate is fixedly connected to the upper end of the moving crossbeam. Pin holes are opened on both sides of the parking plate. A parking pin is inserted and connected to the side of the parking plate. A locking pin is set at the left end of the parking pin. A limit hole is opened on the outer side of the parking pin. A tongue-type pin is inserted and connected to the upper end of the parking pin.

[0007] The tongue-type pin includes a pin, a groove, a fixing rod, a locking tongue, an adjusting groove, and a locking pin. The lower end of the pin has a groove, and the fixing rod is fixedly connected to the inner wall of the groove. The locking tongue is provided inside the groove, and the adjusting groove is provided on the side of the locking tongue. The upper end of the pin has a locking pin.

[0008] Preferably, the diameter of the locking hole is the same as the diameter of the pin hole, and the parking pin is compatible with both the locking hole and the pin hole.

[0009] The above technical solution ensures that the parking pin can be smoothly inserted into the locking hole and the pin hole, achieving precise positioning and connection. This allows the moving crossbeam and the track beam to be stably fixed through the parking plate, effectively preventing unnecessary displacement of the monorail crane due to external factors such as ship swaying when it is parked, thus enhancing the reliability and stability of the parking device.

[0010] Preferably, the locking pin and the parking latch are welded together.

[0011] Through the above technical solution, the welding connection method enables the locking pin and the parking pin to form a solid integral structure.

[0012] Preferably, the pin is adapted to the limiting hole, and the width of the locking tongue is equal to the diameter of the pin.

[0013] With the above technical solution, the width of the locking tongue is equal to the diameter of the pin. When the adjusting groove of the locking tongue is in a vertical state, the pin with the tongue can be inserted into the limiting hole.

[0014] Preferably, the adjusting groove and the fixing rod are slidably connected.

[0015] Through the above technical solution, the locking tongue can move flexibly within the groove, facilitating the operation of the tongue-type pin to lock and unlock the parking pin.

[0016] Preferably, when the latch is in a horizontal position, the left side of the latch is in contact with the parking plate, and the end of the adjusting groove near the parking plate is in contact with the fixing rod.

[0017] With the above technical solution, when parking, the locking hole of the track beam is aligned with the pin hole of the parking plate. The parking pin is inserted into the parking plate from the left pin hole and then into the locking hole of the track beam. The right end of the parking pin extends from the right pin hole. The tongue pin is inserted into the limiting hole. The locking tongue is moved to a horizontal position. At this time, the fixing rod pushes the locking tongue to make it contact the parking plate tightly, thereby locking the parking pin. This ensures that when the ship experiences strong vibration or shaking, the locking tongue can firmly lock the parking pin on the parking plate, ensuring that the monorail is firmly fixed to the track beam, further guaranteeing the self-locking effect and safety of the parking device.

[0018] Compared with the prior art, this utility model provides a self-locking parking device for a marine monorail crane, which has the following advantages:

[0019] 1. The self-locking parking device of this marine monorail crane features a pin that matches the limiting hole, with the locking tongue width equal to the pin diameter. When the adjusting groove of the locking tongue is in a vertical position, it facilitates the insertion of the tongue-tipped pin into the limiting hole. The sliding connection between the adjusting groove and the fixed rod allows the locking tongue to move flexibly within the groove. Locking and unlocking the parking pin can be easily achieved by operating the tongue-tipped pin, which is convenient and quick. When the locking tongue is in a horizontal position, it contacts the parking plate, and the end of the adjusting groove near the parking plate contacts the fixed rod, forming a stable mechanical structure. When the ship experiences strong vibrations or swaying, this structure can firmly lock the parking pin onto the parking plate, ensuring the monorail crane is firmly fixed to the track beam. This significantly improves the self-locking effect and safety of the parking device, effectively preventing serious accidents such as the monorail crane falling into the sea due to accidental loosening of the parking device, thus ensuring the safety of personnel and the integrity of cargo.

[0026] 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.

[0027] Example 1: As Figure 1-5 As shown, the present invention provides a self-locking parking device for a marine monorail crane, which is set on the upper end of a moving crossbeam 1. A track beam 2 is set above the moving crossbeam 1. A locking hole 3 is opened on the side of the track beam 2. A parking plate 4 is fixedly connected to the upper end of the moving crossbeam 1. A pin hole 5 is opened on both sides of the parking plate 4. A parking pin 6 is inserted and connected to the side of the parking plate 4. A locking pin 7 is set on the left end of the parking pin 6. A limit hole 8 is opened on the outer side of the parking pin 6. A tongue-type pin 9 is inserted and connected to the upper end of the parking pin 6.

[0028] The tongue-type pin 9 includes a pin 901, a groove 902, a fixing rod 903, a locking tongue 904, an adjusting groove 905, and a locking pin 906. The lower end of the pin 901 has a groove 902, and the fixing rod 903 is fixedly connected to the inner wall of the groove 902. The locking tongue 904 is provided inside the groove 902, and the side of the locking tongue 904 has an adjusting groove 905. The upper end of the pin 901 has a locking pin 906.

[0029] Specifically, the diameter of the locking hole 3 is the same as the diameter of the pin hole 5, and the parking pin 6 is compatible with both the locking hole 3 and the pin hole 5. The advantage is that it ensures the parking pin 6 can be smoothly inserted into the locking hole 3 and the pin hole 5, achieving precise positioning and connection. This allows the moving crossbeam 1 and the track beam 2 to be stably fixed via the parking plate 4, effectively preventing unnecessary displacement of the monorail crane due to external factors such as ship swaying when it is stopped, thus enhancing the reliability and stability of the parking device.

[0030] Specifically, the locking pin 7 and the parking pin 6 are welded together. The advantage is that the welding connection makes the locking pin 7 and the parking pin 6 form a solid integral structure.

[0031] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0032] Specifically, the pin 901 is adapted to the limiting hole 8, and the width of the latch 904 is equal to the diameter of the pin 901. The advantage is that, since the width of the latch 904 is equal to the diameter of the pin 901, when the adjusting groove 905 of the latch 904 is in a vertical position, the tongue-tipped pin 9 can be inserted into the limiting hole 8.

[0033] Specifically, the adjusting groove 905 and the fixing rod 903 are slidably connected. The advantage is that the locking tongue 904 can move flexibly within the groove 902, facilitating the operation of the tongue-type pin 9 to lock and unlock the parking pin 6.

[0034] Specifically, when the locking tongue 904 is in a horizontal position, its left side contacts the parking plate 4, and the end of the adjusting groove 905 near the parking plate 4 contacts the fixing rod 903. The advantage is that when parking, the locking hole 3 of the track beam 2 is aligned with the pin hole 5 of the parking plate 4. The parking pin 6 is inserted into the parking plate 4 from the left pin hole 5 and into the locking hole 3 of the track beam 2. The right end of the parking pin 6 extends from the right pin hole 5. The tongue-tipped pin 9 is inserted into the limiting hole 8. The locking tongue 904 is moved to a horizontal position. At this time, the fixing rod 903 pushes the locking tongue 904, causing it to contact the parking plate 4 tightly, thus locking the parking pin 6. This ensures that when the ship experiences strong vibrations or swaying, the locking tongue 904 can firmly lock the parking pin 6 onto the parking plate 4, ensuring the monorail is firmly fixed to the track beam 2, further guaranteeing the self-locking effect and safety of the parking device.

[0035] Working principle: Before stopping, slowly move the monorail until the pin holes 5 on both sides of the parking plate 4 at the upper end of the moving beam 1 are precisely aligned with the locking holes 3 on the side of the track beam 2. Insert the parking pin 6 into one side pin hole 5 of the parking plate 4, allowing it to pass through the pin hole 5 of the parking plate 4 and the locking hole 3 of the track beam 2 in sequence, until the right end of the parking pin 6 protrudes a suitable length from the pin hole 5 on the other side of the parking plate 4, ensuring the parking pin 6 is fully inserted. Then, pick up the tongue pin 9 and align the pin rod 901 with the parking pin... With the locking tongue 904 in a vertical position, insert the tongue-type pin 9 into the limiting hole 8 on the pin 6 until the pin 901 is fully inserted. Move the locking tongue 904 so that it slides around the fixing rod 903 in the adjusting groove 905 until the locking tongue 904 is in a horizontal position. At this time, the left side of the locking tongue 904 is in close contact with the parking plate 4, and the end of the adjusting groove 905 near the parking plate 4 is in contact with the fixing rod 903, forming a stable locking structure, thereby firmly locking the parking pin 6 and completing the parking operation.

[0036] 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.
