[0001] This utility model relates to the field of fire extinguishing agent transportation technology, specifically a foam fire extinguishing agent transfer device. Background Technology

[0002] The transfer of foam extinguishing agent containers within the workshop is generally accomplished using small handcarts. However, the small handcarts are not stable enough in holding the foam extinguishing agent containers, and the containers are prone to shaking or even falling during the transfer process. This may not only lead to leakage of foam extinguishing agent, causing waste and environmental pollution, but may also cause safety accidents.

[0003] Chinese patent CN221757588U discloses a foam fire extinguishing agent transfer device, including a vehicle body with a support plate fixedly connected to its top. A handle is fixedly connected to one side of the support plate. A clamping mechanism is provided on the support plate. The clamping mechanism includes a clamping plate, a rotating rod, a pull rod, a positioning component, and a moving component. A through groove is opened on one side of the support plate, and the pull rod is disposed inside the through groove. Multiple rotating rods are disposed between the clamping plate and the pull rod.

[0004] The aforementioned existing technology can fix the foam extinguishing agent container with a pair of clamps to ensure the safety of transportation. However, the above devices can only clamp at a fixed height, which has poor adaptability and is difficult to meet the transportation needs of foam extinguishing agent containers of different specifications and shapes. With the widespread application of foam extinguishing agents in fire protection and other fields, higher requirements have been put forward for the safety, convenience and adaptability of its transportation device. Therefore, the development of a new type of foam extinguishing agent transportation device has important practical significance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a foam extinguishing agent transfer device, which solves the problems of poor adaptability and inconvenience in loading and unloading existing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foam extinguishing agent transfer device, comprising a base and wheels disposed below the base, wherein a bracket is fixedly mounted on one side of the upper wall of the base, characterized in that an adjustment box is fixedly installed on the side wall of the bracket, a screw is rotatably mounted inside the adjustment box, a longitudinally arranged sliding groove is provided on the side wall of the adjustment box, a slider is screwed onto the screw and slidably connected to the sliding groove, a clamping assembly is provided on the side wall of the slider, a sliding cavity is provided on one side wall of the base, a horizontally sliding carriage is provided inside the sliding cavity, an auxiliary plate is hinged to the side wall of the carriage, and the side of the auxiliary plate away from the carriage can extend to the outside of the sliding cavity and tilt downward to form an inclined structure.

[0007] Preferably, the clamping assembly includes a transmission box fixedly connected to the slider, a pair of pull rods are rotatably installed in the transmission box, a transverse groove is provided on the side wall of the transmission box, a pair of movable blocks that are slidably connected to the pull rods are slidably arranged in the transverse groove, and a clamping claw is detachably installed on the side wall of the movable block through an insert structure.

[0008] Preferably, the insertion structure includes a sleeve fixedly disposed on the side wall of the movable block, a plug block that can be inserted into the sleeve is fixedly disposed at one end of the gripper, a through hole is opened on the upper wall of the sleeve, a pin is slidably inserted into the through hole, a lifting plate is provided at the upper end of the pin, a spring is installed between the lifting plate and the sleeve, and a socket for the pin to be inserted is provided on the upper wall of the plug block.

[0009] Preferably, a positioning bolt is screwed onto the lower wall of the base near the sliding cavity, and a positioning hole is provided on the lower wall of the auxiliary plate for the positioning bolt to be inserted. When the auxiliary plate is fully slid into the sliding cavity, the positioning hole is aligned with the positioning bolt.

[0010] Preferably, the gripping surface of the gripper is provided with a rubber pad.

[0011] Preferably, the support sidewall is provided with a pusher.

[0012] Preferably, the slide cavity is provided with guide grooves on both sides, and the slide frame is provided with guide blocks at both ends that match the guide grooves.

[0013] Beneficial effects

[0014] This utility model provides a foam extinguishing agent transfer device, which has the following beneficial effects:

[0015] By adjusting the screw inside the box, the slider connected to the screw moves up and down in the groove, thereby adjusting the height of the clamping assembly. This allows for the selection of an appropriate clamping height for different sizes of extinguishing agent containers, ensuring a secure hold. In the clamping assembly, the rotation of the pull rod causes a pair of moving blocks to move towards or away from each other in the transverse groove, which in turn causes the grippers to clamp or release the foam extinguishing agent container. Rubber pads are provided on the gripping surfaces of the grippers, increasing the friction between the grippers and the container and preventing damage to the container surface. This ensures the stability of the foam extinguishing agent container during transport and effectively prevents the container from shaking or falling.

[0016] The design of the slide frame and auxiliary plate in the sliding cavity on one side wall of the base makes loading and unloading foam extinguishing agent containers more convenient. When it is necessary to load or unload the container, the auxiliary plate is pulled out from the sliding cavity and tilted downward to form a slope structure, which makes it easy to push the container up or down the transfer device along the slope. After loading or unloading, the auxiliary plate is slid into the sliding cavity and fixed by the cooperation of the positioning bolts and positioning holes. The operation is simple and quick, which greatly improves the transfer efficiency.

[0017] The design of the insert structure allows the grippers to be easily disassembled and replaced. When it is necessary to transport foam extinguishing agent containers of different sizes or shapes, simply lift the lifting plate upwards to allow the pin to overcome the spring force and be pulled out of the insertion hole. The insert block of the gripper can then be removed from the insert sleeve and a suitable gripper can be replaced. This design improves the adaptability of the transport device and can meet the transport needs of different containers. Attached Figure Description

A gripper 14 is detachably installed on the side wall of the moving block 13 through an insert structure.

[0026] By adopting the above technical solution, when clamping the foam extinguishing agent container, rotating the pull rod 11 causes the moving block 13 to drive the gripper 14 to clamp or release the container, ensuring that the container will not shake or fall during transportation, thus improving the safety of transportation.

[0027] In this embodiment, the insertion structure includes a sleeve 15 fixedly disposed on the side wall of the movable block 13, a plug block 16 that can be inserted into the sleeve 15 is fixedly disposed at one end of the gripper 14, the upper wall of the sleeve 15 is provided with a through hole, a pin 17 is slidably inserted into the through hole, a lifting plate 18 is provided at the upper end of the pin 17, a spring 19 is installed between the lifting plate 18 and the sleeve 15, and the upper wall of the plug block 16 is provided with a socket for the pin 17 to be inserted.

[0028] By adopting the above technical solution, when replacing the gripper 14, the lifting plate 18 is lifted upwards to pull the pin 17 out of the socket and remove the insert block 16 of the gripper 14 from the insert sleeve 15; when installing the gripper 14, the insert block 16 is inserted into the insert sleeve 15 and the pin 17 is inserted into the socket under the action of the spring 19, which facilitates the disassembly and replacement of the gripper 14, enabling the transfer device to adapt to foam extinguishing agent containers of different specifications and shapes, and improving the adaptability of the device.

[0029] In this embodiment, a positioning bolt 20 is screwed onto the lower wall of the base 1 near the sliding cavity, and a positioning hole for the positioning bolt 20 is opened on the lower wall of the auxiliary plate 9. When the auxiliary plate 9 is completely slid into the sliding cavity, the positioning hole is aligned with the positioning bolt 20.

[0030] By adopting the above technical solution, when loading and unloading the foam extinguishing agent container, the auxiliary plate 9 is pulled out of the sliding cavity to form an inclined structure; after loading and unloading, the auxiliary plate 9 is slid into the sliding cavity and the positioning bolt 20 is tightened to fix the auxiliary plate 9.

[0031] In this embodiment, the gripping surface of the gripper 14 is provided with a rubber pad.

[0032] By adopting the above technical solution, the rubber pad increases the friction between the gripper 14 and the container, while protecting the container surface from damage, further improving the stability and safety of the clamping.

[0033] In this embodiment, the support 3 is further configured such that a pusher 21 is provided on the side wall.

[0037] Example: In use, according to the specifications and shape of the foam extinguishing agent container to be transported, select the appropriate clamp 14 and install it on the moving block 13. Specifically, lift the lifting plate 18 upward so that the pin 17 overcomes the elastic force of the spring 19 and is pulled out of the socket. Then the insert block 16 of the clamp 14 can be removed from the socket 15. Replace with a suitable clamp 14 so that the insert block 16 is inserted into the socket 15. Release the lifting plate 18, and the spring 19 will drive the pin 17 to descend and reset, so that the pin 17 is inserted into the socket, thus completing the fixing of the clamp 14.

[0038] Then, according to the height of the foam extinguishing agent container, rotate the screw 5 in the adjustment box 4. The upper end of the screw 5 is equipped with a handwheel for easy operation. The rotation of the screw 5 drives the slider 7 to move up and down in the slide groove 6, adjusting the clamping component to a suitable height.

[0039] Loosen the positioning bolt 20 to separate it from the positioning hole. Then pull the auxiliary plate 9 out of the sliding cavity and tilt it downward to form a slope structure. Push the foam extinguishing agent container up the slope onto the transfer device so that the container is between the grippers 14. Turn the handwheel of the pull rod 11 to make a pair of moving blocks 13 move towards each other in the transverse groove 12, which will drive the grippers 14 to clamp the container. After loading and unloading, slide the auxiliary plate 9 into the sliding cavity so that the positioning hole is aligned with the positioning bolt 20. Tighten the positioning bolt 20 to fix the auxiliary plate 9 in the sliding cavity. The operator holds the pusher 21 on the side wall of the bracket 3 and pushes the transfer device to transfer the foam extinguishing agent container to the designated location.
