[0001] This utility model belongs to the field of ship unloaders, and in particular relates to a fire early warning device for the driver's cab of a ship unloader. Background Technology
[0002] In the port logistics and transportation system, ship unloaders are crucial large-scale mechanical equipment, undertaking the important task of efficiently unloading cargo from ships to the dock. Their stable operation plays a decisive role in ensuring the continuity and efficiency of port operations. The ship unloader operator's cab, as the core work area for operators, is filled with various complex electrical control equipment, wiring, and precision instruments. During prolonged high-load operation, these devices inevitably generate heat, and due to the complex port environment, factors such as dust and humidity can create fire hazards in the electrical wiring and equipment. In the event of a fire, not only will expensive equipment be damaged, forcing the ship unloader to shut down for repairs and affecting the port's cargo loading and unloading schedule, but it may also endanger the lives of operators, causing irreparable and significant losses. Therefore, equipping the ship unloader operator's cab with an effective fire early warning system is of paramount importance.
[0003] Currently, smoke sensors are commonly used in the operator's cab of ship unloaders for fire early warning. However, most existing smoke sensors are bolted to the cab platform, making installation cumbersome, time-consuming, and labor-intensive. Moreover, when a smoke sensor malfunctions and needs replacement, tools are required to remove the bolts, which is inconvenient and inefficient, hindering the normal maintenance and timely repair of the fire early warning system.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] This utility model provides a fire early warning device for the driver's cab of a ship unloader, as shown in the attached figure. Figure 1-8As shown, the system includes a first housing 10, a limiting guide rail 70, a limiting plate 50, a clamping member 60, and a second housing 20. The first housing 10 is adapted to be fixed on the platform of the driver's cab. The limiting guide rail 70 is fixed to the bottom of the first housing 10 and is arranged radially along the first housing 10. The limiting plate 50 is rotatably installed inside the first housing 10, and the limiting plate 50 has arc-shaped slots 52 distributed in the circumferential direction. The clamping members 60 are arranged circumferentially in the first housing 10, and the bottom of the clamping members 60 is slidably connected to the limiting guide rail 70. The clamping members 60 correspond one-to-one with the arc-shaped slots 52 and slide through the arc-shaped slots 52 for clamping the smoke sensor 40. The second housing 20 is adapted to be fitted onto the first housing 10 and has an internal connecting structure for driving the limiting plate 50 to rotate. A limiting assembly 30 is provided between the second housing 20 and the first housing 10. A smoke opening 21 is provided on the end face of the second housing 20. When the limiting plate 50 rotates, the clamping member 60 can slide along the limiting guide rail 70 under the action of the arc-shaped slot 52. In use, the smoke sensor 40 is clamped and fixed by the clamping member 60, which can prevent the smoke sensor 40 from sliding in the first housing 10 due to inertia when the driver's cab is in motion, and can form a stable limit for the smoke sensor 40.
[0023] In this embodiment, the first housing 10 is pre-fixed to the tabletop of the driver's cab. Initially, the clamping member 60 is located at the outer end of the arc-shaped slot 52. When installing the smoke sensor 40, it is first placed between the clamping members 60, and then the second housing 20 is fitted onto the first housing 10. The first housing 10 is then rotated, causing the limiting plate 50 to rotate. The clamping member 60 moves towards the smoke sensor 40 under the action of the arc-shaped slot 52. When the smoke sensor 40 is clamped, the second housing 20 is fixed to the first housing 10 by the limiting component 30. When removing the smoke sensor 40, the second housing 20 is rotated in the opposite direction and removed. The clamping member 60 moves away from the smoke sensor 40 under the action of the arc-shaped slot 52, and the smoke sensor 40 can then be removed for replacement. The entire replacement process does not require removing the first housing 10 from the tabletop, making the operation simple and convenient, greatly improving replacement efficiency and reducing maintenance difficulty.
[0024] Specifically, multiple smoke openings 21 are provided and are spaced apart along the circumferential direction on the end face of the second housing 20. The smoke openings 21 are fan-shaped openings.
[0025] In one embodiment, there are two clamping members 60, which are symmetrically arranged on both sides of the smoke sensor 40.
[0026] In one embodiment, the limiting guide rail 70 has a wedge-shaped groove 71. The clamping member 60 includes a support rod 62, a wedge-shaped limiting block 63, and an arc-shaped clamping plate 61. The wedge-shaped limiting block 63 is fixedly mounted on the bottom end of the support rod 62 and is slidably disposed in the wedge-shaped groove 71. The arc-shaped clamping plate 61 is fixedly mounted on the top end of the support rod 62 and is used to clamp the smoke sensor 40.
[0027] In one embodiment, the inner wall of the arc-shaped clamping plate 61 is provided with a rubber layer 611, which can prevent rigid clamping from damaging the smoke sensor 40, and can also increase the friction between the arc-shaped clamping plate 61 and the smoke sensor 40, thereby improving the stability of the fixation.
[0028] In one embodiment, the limiting plate 50 has an opening h, and strip-shaped through holes 51 are distributed at intervals between the arc-shaped slots 52. The connecting structure includes a connecting plate 22 fixed to the inner wall of the end face of the second housing 20. The connecting plate 22 is adapted to be inserted into the strip-shaped through holes 51 to drive the limiting plate 50 to rotate with the second housing 20. During installation, the second housing 20 is sleeved on the first housing 10, and the connecting plate 22 is inserted into the strip-shaped through holes 51, forming a connection between the first housing 10 and the second housing 20. When the second housing 20 is rotated, the limiting plate 50 can be driven to rotate in the first housing 10 through the connecting plate 22. It should be noted that when the second housing 20 is sleeved on the first housing 10, the bottom end of the connecting plate 22 can penetrate through the strip-shaped through holes 51, but is higher than the upper end face of the limiting guide rail 70, and will not touch the limiting guide rail 70 during rotation.
[0029] In one embodiment, a limiting groove 13 is formed on the side wall of the first housing 10. A limiting through hole 23 is formed on the side wall of the second housing 20. The limiting component 30 includes a limiting pin 31, which is movably inserted into the limiting groove 13. The limiting pin 31 is connected to the inner wall of the limiting groove 13 by an elastic member 32. The limiting pin 31 can pass into the limiting through hole 23 under the action of the elastic member 32 to fix the second housing 20. During installation, the limiting pin 31 is first pressed into the limiting groove 13 to ensure that the second housing 20 can be smoothly fitted onto the first housing 10. Then, the second housing 20 is rotated. When the clamping member 60 clamps the smoke sensor 40, the limiting through hole 23 rotates to a position aligned with the limiting pin 31. The limiting pin 31 passes into the limiting through hole 23 under the action of the elastic member 32, thereby fixing the second housing 20 to the first housing 10.
[0030] Preferably, there are two limiting pins 31, which are symmetrically arranged on both sides of the first housing 10.
[0031] In one embodiment, the fire early warning device for the unloader's cab further includes a top block with an end plate at its end. The top block can pass through a limiting through hole 23 to push a limiting pin 31 out of the limiting through hole 23. During disassembly, the top block is first inserted into the limiting through hole 23, and the top block is used to push the limiting pin 31 out of the limiting through hole 23, ensuring that the second housing 20 can be rotated smoothly. At this time, the end plate of the top block abuts against the side wall of the second housing 20, facilitating the subsequent removal of the top block. Specifically, the limiting through hole 23 is a cylindrical through hole, and the top block is a cylindrical structure suitable for insertion into the limiting through hole 23. The top block and the end plate can be made of rubber.
[0032] In one embodiment, the elastic element 32 is a compression spring.
[0033] In one embodiment, the first housing 10 has a cylindrical structure, and an annular groove 12 is formed on the inner wall of the first housing 10. The limiting plate 50 is circular, and the edge of the limiting plate 50 is installed in the annular groove 12 and can rotate relative to the first housing 10.
[0034] In one embodiment, the first housing 10 has a mounting plate 11 at its tail end. The mounting plate 11 has a plurality of mounting holes 111 along the circumferential direction. The mounting plate 11 is adapted to be mounted on the table surface of the driver's cab by bolts.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
