[0024] The embodiment of the present application provides a split type fire extinguishing and fire-fighting stacker and a fire-fighting method, avoids the redundant configuration of the traditional multi-point fixed fire extinguishing device, shortens the fire-fighting response time, and improves the flexibility of the stacker and the utilization rate of the storage space.

[0025] The technical solutions provided by the present application will be described in more detail below. Figures 1-7 The technical solutions provided by the present application will be described in more detail below.

[0026] Embodiment 1 Referring to Figures 1-7 The split type fire extinguishing and fire-fighting stacker provided by the present application includes a hook and claw locking mechanism 2, a spray head mounting rack 4, a fire extinguishing agent storage device 31 and a stacker body 1 with a loading platform 13, wherein: the spray head mounting rack 4 and the fire extinguishing agent storage device 31 are located on the stacker body 1 and move with the stacker body 1; the spray head mounting rack 4 is provided with fire extinguishing spray heads 35, and all the fire extinguishing spray heads 35 can be in communication with the fire extinguishing agent storage device 31; the hook and claw locking mechanism 2 is arranged on the loading platform 13, and the hook and claw locking mechanism 2 can be hooked and fixed with the spray head mounting rack 4 when the loading platform 13 is lowered, so as to lift the spray head mounting rack 4; and the hook and claw locking mechanism 2 can be separated from the spray head mounting rack 4 under the action of external force.

[0027] The loading platform 13 is the core working platform of the stacker for performing cargo storage and retrieval operation in the prior art, which realizes vertical lifting movement along the stand 11 through a guide rail, a chain wheel and chain or a gear and rack mechanism, and is a conventional structure of the stacker, which will not be described here.

[0028] The spray head mounting rack 4 is used to carry the fire extinguishing spray head 35 and is in the form of a frame. Referring to Figures 1-3 In the embodiment of the present application, the spray head mounting rack 4 is placed on the fire extinguishing agent storage device 31 and is in sliding or rolling guide cooperation with the stacker body 1 in the vertical direction, ensuring smooth lifting process. The fire extinguishing agent storage device 31 is used to store a sealed container of liquid or gas-liquid mixed state fire extinguishing agent.

[0029] In the normal cargo access operation state, the hook and claw locking mechanism 2 is in a separated state from the spray head mounting rack 4, as shown in Figure 1 The spray head mounting rack 4 is at rest in the low position and does not affect the lifting movement of the cargo carrying platform 13; referring to Figures 2-3 When a fire occurs, the cargo carrying platform 13 is lowered to a preset position, at which time the hook and claw locking mechanism 2 is clamped with the spray head mounting rack 4; then the cargo carrying platform 13 is raised, and the spray head mounting rack 4 is lifted as a whole by the hook and claw locking mechanism 2, so that the fire extinguishing spray head 35 carried by the spray head mounting rack 4 reaches the target height; this lifting process does not require an additional power source and is completely powered by the lifting drive system of the stacker body 1, and the action is reliable and responds in time.

[0030] The embodiment provides a specific implementation of the hook and claw locking mechanism 2, referring to Figures 4-7 The hook and claw locking mechanism 2 includes a mounting seat 25 and at least two claw parts 21, wherein: the mounting seat 25 is fixed to the bottom of the cargo carrying platform 13, and the at least two claw parts 21 are oppositely arranged on the mounting seat 25; the bottom of the claw part 21 is provided with a clamping hook 211, the spray head mounting rack 4 is provided with a lug 5, the two clamping hooks 211 can be inserted into the lug 5 and clamped and fixed with the lug 5, and the clamping hook 211 can be detached from the lug 5 under the action of an external force; the lug 5 includes a side plate 51, a plurality of side plates 51 are fixedly connected with the side wall of the spray head mounting rack 4 and surround a frame structure, the clamping hook 211 can pass through the frame structure and be hooked at the bottom of the frame structure.

[0031] Referring to Figures 4-7 The clamping hooks 211 on the two claw parts 21 are in an open state in the initial state, and during the lowering process of the cargo carrying platform 13, the clamping hooks 211 move above the lug 5, slide into the inner wall of the side plate 51 of the frame structure, and are finally hooked at the bottom edge of the frame structure of the lug; when unlocking is required, a transverse external force is applied to the two claw parts 21 (for example, an electrically controlled push rod is used to push a single claw part 21 to swing outward, or an auxiliary device is used to press the two claw parts 21), so that the two clamping hooks 211 are detached from the bottom of the frame structure, thereby realizing separation from the spray head mounting rack 4; the external force can be provided by manual operation, a pneumatic element, an electric push rod or an electromagnetic driving device, and the specific driving form can be selected according to the system automation level and response speed requirement.

[0032] In this embodiment, the two claws 21 are arranged opposite each other and move synchronously, which significantly improves the anti-eccentric load capacity and overall stability of the connection structure; the hook lug 5 adopts a frame structure surrounded by multiple side plates 51, which provides an insertion guide path for the hook 211 and ensures the stability of the connection structure between the nozzle mounting bracket 4 and the hook 211.

[0033] As an alternative implementation, see [link to implementation details]. Figures 4-7 As shown, in the same set of hook locking mechanisms 2, two claws 21 are symmetrically arranged along the vertical axis of symmetry of the mounting base 25; the top of the claw 21 is rotatably connected to the mounting base 25 through a pin 22, so that the hooks 211 can move towards each other or away from each other under the action of external force; the hooks 211 are provided with an inclined guide surface 2110, which gradually approaches the axis of symmetry of the two claws 21 in the direction from top to bottom.

[0034] The top of the claw 21 is rotatably connected to the mounting base 25 via a pin 22, allowing the hooks 211 to flexibly retract towards each other or expand away from each other under external force, adapting to insertion or disengagement from the hook lug 5. The inclined guide surface 2110 is located on the outer surface of the front end of the hook 211, and is used to first contact the edge of the side plate 51 of the hook lug 5 during the descent of the claws, and convert the vertical downward motion into a horizontal separation force, driving the two claws 21 to rotate outward around the pin 22, thereby guiding the two claws 21 to retract to smoothly insert into the hook lug 5.

[0035] See Figures 1-7 When the loading platform 13 drives the hook locking mechanism 2 to descend and approach the nozzle mounting frame 4, the inclined guide surface 2110 at the front end of the two hooks 211 first contacts the edge of the side plate 51 of the hook ear 5. As the descent continues, the inclined guide surface 2110 is pushed by the side plate 51, causing the two hooks 211 to move relative to each other. After the hooks 211 pass the top of the side plate 51, the two claws 21 spring back and the hooks 211 are embedded in the bottom of the hook ear 5 frame. The entire hooking process is characterized by balanced force, coordinated action, and reliable response, which significantly improves the success rate and repeatability of the automatic docking of the hooks and hook ears 5.

[0036] As an optional implementation, the hook locking mechanism 2 of this embodiment further includes an elastic reset component, which is located between the two claw portions 21, and the opposite ends of the elastic reset component abut against the opposite sides of the two hooks respectively.

[0037] See Figures 4-7 As shown, the elastic reset assembly of this embodiment includes a fixing block 24 and at least two reset springs 23. The fixing block 24 is fixed on the mounting base 25 and located between two claws 21. The two reset springs 23 are respectively fixed on opposite sides of the fixing block 24, and the other end of the reset spring 23 is fixed to the corresponding claw 21. The two hooks 211 can move relative to each other under the action of the groove wall of the hook lug 5 and compress the reset spring 23.

[0038] As shown in Figures 4-7 As shown in FIG. 4, when the loading platform 13 is lowered, the hooks 211 extend into the hook ears 5, and the extrusion of the inner groove wall of the hook ears 5 forces the two hooks 211 to contract (compress the return springs 23) towards each other, the hooks 211 enter the hook groove locking position, and the elastic restoring force of the return springs 23 immediately pushes the hooks 211 to expand backward, achieving rapid locking.

[0039] As shown in Figures 4-7 As shown in FIG. 5, during the unlocking stage of the hooks 211 and the hook ears 5 (such as after the fire is extinguished and the loading platform 13 is lowered), external force causes the hooks 211 to compress the return springs 23 again and separate, the hooks 211 separate from the frame structure of the hook ears 5, and the uniform elastic force of the return springs 23 ensures smooth separation.

[0040] The above structure can quickly realize the locking and separation of the claw part 21 and the nozzle mounting rack 4, and is convenient to operate.

[0041] As an optional embodiment, as shown in Figures 1-3 As shown in FIG. 6, the stacker body 1 of the embodiment further includes a stand column 11, a lower cross beam 12 and a lower frame 131, wherein: the stand column 11 is vertically arranged, the lower cross beam 12 is fixed to the bottom end of the stand column 11, and the fire extinguishing agent storage device 31 is placed on the lower cross beam 12; the loading platform 13 is arranged to be vertically movable along the stand column 11, the lower frame 131 is fixed to the bottom of the loading platform 13, and the hook claw locking mechanism 2 is fixed to the lower frame 131; when the nozzle mounting rack 4 is separated from the hook claw locking mechanism 2, the nozzle mounting rack 4 is placed on the lower cross beam 12 or the fire extinguishing agent storage device 31, and the nozzle mounting rack 4 is in sliding or rolling connection with the stand column 11 in the vertical direction.

[0042] As shown in Figures 1-3 As shown in FIG. 7, the lower cross beam 12 is a horizontal bearing beam, and its two ends are fixedly connected with the bottom ends of the stand columns 11, and the connection modes include but are not limited to bolt fastening, welding or pin shaft 22 positioning; the surface of the lower cross beam 12 is flat, and is used for supporting the fire extinguishing agent storage device 31. The fire extinguishing agent storage device 31 is placed on the lower cross beam 12, and a slip-resistant cushion layer or a limiting stopper can be arranged therebetween to prevent displacement of the device caused by transportation vibration; the fire extinguishing agent storage device 31 can be a closed pressure tank or a normal-pressure liquid storage tank, and the internal fire extinguishing agent is a foam fire extinguishing agent or the like.

[0043] In the embodiment, in the non-fire state, the spray head mounting rack 4 is reliably supported by the lower cross beam 12 or the fire extinguishing agent storage device 31, does not occupy the stroke space of the loading platform 13, and does not affect the normal storage and access operation; when the loading platform 13 is lowered to hook and lock the mechanism 2 and the spray head mounting rack 4, the spray head mounting rack 4 is separated from the original supporting surface and stably rises along the guide structure of the stand 11 under the traction of the hook and lock mechanism 2; the stand 11 serves as a common bearing and guide reference to stably lift the spray head mounting rack 4; the fire extinguishing agent storage device 31 serves as a fire extinguishing agent container and also as a temporary support of the spray head mounting rack 4, and the overall layout is compact and convenient to assemble.

[0044] As an optional embodiment, referring to Figures 1-3 , the split fire extinguishing and fire stacking machine further comprises a pipeline winder 33, a conveying pipeline 34 and a pump body 32, wherein the conveying pipeline 34 is connected to all the fire extinguishing spray heads 35 and the fire extinguishing agent storage device 31, the pump body 32 is arranged on the conveying pipeline 34 and used for pumping the fire extinguishing agent, and the pipeline winder 33 is arranged on the stacking machine body 1 and can release or wind the conveying pipeline 34 when the loading platform 13 drives the fire extinguishing spray heads 35 to rise or fall. The conveying pipeline 34 is a flexible hose or a telescopic metal bellows. The pipeline winder 33 is a mature technology and will not be described here.

[0045] When the loading platform 13 rises, the fire extinguishing spray heads 35 rise with it, the conveying pipeline 34 is unfolded, and the pipeline winder 33 releases the conveying pipeline 34; when the loading platform 13 falls, the fire extinguishing spray heads 35 fall with it, and the pipeline winder 33 winds the conveying pipeline 34 synchronously.

[0046] The above structure of the embodiment provides stable pressure and flow of the fire extinguishing agent conveying capacity by the pump body 32, and guarantees continuous and effective spraying of the high-altitude spray head. The pipeline winder 33 can wind the conveying pipeline 34 synchronously with the lifting of the loading platform 13, avoiding knotting of the conveying pipeline 34 or interference with other structures.

[0047] As an optional embodiment, referring to Figure 4 and Figure 5 , the number of the hook and lock mechanisms 2 is multiple, the hook and lock mechanisms 2 are arranged on the peripheral walls of the lower frame 131 at intervals, and the positions of the hook ears 5 correspond to the positions of the hook and lock mechanisms 2 one by one.

[0048] The number of the hook and lock mechanisms 2 is two, three, four or more, and the specific number can be adaptively set; for example, four, which are arranged on the front, rear, left and right four side walls of the lower frame 131, and the embodiment of the application does not specially limit this.

[0049] In this embodiment, when the plurality of hook locking mechanisms 2 work cooperatively, the clamps 211 of each claw portion 21 synchronously extend into the corresponding lug 5, and move towards each other under the action of the lug 5 groove wall to compress the elastic reset assembly, finally realizing the multi-point synchronous locking of the loading platform 13 and the nozzle mounting rack 4, improving the stability of the structure, and preventing the nozzle mounting rack 4 from falling off.

[0050] Embodiment 2 The embodiment provides a fire extinguishing method using the split fire extinguishing fire stacker. The fire extinguishing method comprises the following steps: when there is no fire, the stacker body 1 performs normal goods storage and transportation work, at this time, the hook locking mechanism 2 and the nozzle mounting rack 4 are in a disengaged state; when a fire occurs, the loading platform 13 is lowered, the hook locking mechanism 2 and the nozzle mounting rack 4 are hooked and fixed; the stacker body 1 moves, and at the same time, the loading platform 13 lifts the nozzle mounting rack 4, so that the fire extinguishing nozzle 35 aims at the fire point for fire extinguishing.

[0051] The movement of the stacker body 1 refers to the horizontal movement of the stacker along the lane track, and the positioning to the target shelf column. Aiming at the fire point refers to adjusting the spatial position of the fire extinguishing nozzle 35 to match the coordinates of the fire point through the cooperation of the X-axis (movement) and the Z-axis (lifting) of the stacker body 1, so that the spraying direction covers the fire source area.

[0052] In this embodiment, the fire extinguishing device moves with the stacker, and does not need to add a special fire fighting channel or a fixed spraying point, so that the timeliness of initial fire extinguishing is significantly improved.

[0053] In this embodiment, the disengaged state of the hook locking mechanism 2 and the nozzle mounting rack 4 is maintained when there is no fire, so that the normal operation ability of the stacker is ensured; when a fire occurs, the actions of lowering the loading platform 13, hooking, moving and lifting, accurately aiming and shooting fire extinguishing are sequentially performed, and the combination and integration of the logistics function and the fire fighting function are realized by relying on the inherent movement mechanism of the stacker body 1. The whole method does not change the original control architecture of the stacker, and the fire extinguishing device can be quickly deployed in the existing automatic stereoscopic warehouse.

[0054] As an optional implementation, the fire extinguishing method further comprises the following steps: after the fire extinguishing is completed, the conveying pipeline 34 between the fire extinguishing nozzle 35 and the fire extinguishing agent storage device 31 is collected while the loading platform 13 is lowered; the loading platform 13 pulls the nozzle mounting rack 4 to the target position, the hook locking mechanism 2 is disengaged from the nozzle mounting rack 4 under the action of external force, so that the loading platform 13 and the nozzle mounting rack 4 are disengaged; and the stacker body 1 performs normal goods storage and transportation work.

[0055] In this embodiment, the cargo platform 13 is separated from the spray head mounting rack 4, which can be normally separated after extinguishing the fire. The stacker body 1 can be fully reused as a conventional logistics equipment, and its basic access performance is not sacrificed due to the integrated fire-fighting function, thereby ensuring the overall operation continuity and equipment utilization rate of the warehouse.

[0056] The fire-fighting method provided in this embodiment is that the plurality of fire-fighting sprays of the foam fire-fighting system are connected with the fire-fighting spray fixing rack. When the hook and claw locking mechanism 2 is in the locking state, the upward (or downward) movement of the cargo platform 13 can make the fire-fighting sprays move upward (or downward) together. When the cargo platform 13 moves upward together with the fire-fighting sprays, the pipeline stored in the pipeline winder 33 is pulled out to a corresponding height.

[0057] When there is no fire, the stacker performs the conventional cargo access and handling work. In this state, the hook and claw locking mechanism 2 cannot be locked, that is, the clamping hook 211 cannot be inserted into the corresponding hook lug 5 of the spray head mounting rack 4.

[0058] When a fire occurs, the cargo platform 13 of the stacker is lowered after the lowering condition is met. The cargo platform 13 is lowered to make the clamping hook 211 inserted into the corresponding hook lug 5 of the spray head mounting rack 4, so as to realize the locking of the hook and claw locking mechanism 2 and the spray head mounting rack 4. The stacker body 1 moves, and the cargo platform 13 is raised to make the fire-fighting spray 35 aligned with the fire point. The pump body 32 is opened, the foam liquid or other fire extinguishing agent in the fire extinguishing agent storage device 31 is input to the fire-fighting spray 35 near the fire point through the pipeline of the pipeline winder 33, and the fire is extinguished.

[0059] After the fire is extinguished, the cargo platform 13 is lowered, and the pipeline winder 33 synchronously performs the storage work of the conveying pipeline 34. The cargo platform 13 is lowered to a position where the spray head mounting rack 4 and the fire extinguishing agent storage device 31 are just in contact, the clamping hook 211 and the hook lug 5, and the cargo platform 13 and the spray head mounting rack 4 are separated. The stacker can perform the conventional cargo access and handling work.
