[0098] Optionally, one of the first plug-in portion 163 and the second plug-in portion 164 is a male plug, and the other is a female plug. Alternatively, one of the first plug-in portion 163 and the second plug-in portion 164 is a first lock buckle, and the other is a second lock buckle.

[0099] Optionally, the safety belt assembly 160 includes a rope, that is, the rescue device is tied and fixed by the rope.

[0100] like Figure 3 and Figure 7 As shown, in some embodiments, optionally, the guardrail 120 is also provided with an entrance and exit 123, and the entrance and exit 123 is connected to the working bin 130; the working bucket 100 also includes an armrest 170, which is provided at the entrance and exit 123 and is rotatably connected to the guardrail 120. When the entrance and exit 123 is opened, the armrest 170 can be rotated to the target position relative to the guardrail 120; wherein, when the armrest 170 is located at the target position, along the height direction of the working bin 130, at least part of the armrest 170 is opposite to the entrance and exit 123.

[0101] In this embodiment, the working bucket 100 is defined to further include a handrail 170. Specifically, the handrail 170 is disposed at the entrance 123, and the handrail 170 is rotatably connected to the guardrail 120. Optionally, the working bucket 100 further includes a pin, and the handrail 170 is rotatably connected to the guardrail 120 via the pin.

[0102] The entrance and exit 123 is connected to the working chamber 130 . It is understandable that during the fire rescue process, the rescued persons and the injured persons transferred by rescue devices such as wheelchairs generally enter the working chamber 130 through the entrance and exit 123 .

[0103] When the rescued person or wheelchair needs to enter through the entrance 123, the handrail 170 can be rotated to the target position. When the handrail 170 is rotated to the target position, at least a part of the handrail 170 is opposite to the entrance 123 along the height direction of the working chamber 130, that is, the handrail 170 is located above the entrance 123, so that the entrance 123 is in a fully open state, which facilitates the rescued person and rescue equipment such as wheelchairs to enter the working chamber 130 through the entrance 123, which is conducive to further improving the rescue efficiency.

[0104] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the working bucket 100 further includes a buffer member 180 , which is disposed at the mounting interface 121 and located between the guardrail 120 and the functional component 140 .

[0105] In this embodiment, it is defined that the work bucket 100 also includes a buffer member 180. Specifically, the buffer member 180 is arranged at the installation interface 121, and the buffer member 180 is located between the guardrail 120 and the functional component 140, so that during the installation or removal of the functional component 140 and in the process of using the functional component 140 for rescue, the impact and wear between the functional component 140 and the guardrail 120 can be reduced, which is beneficial to extending the service life of the functional component 140 and the guardrail 120.

[0106] Optionally, the buffer member 180 is a rubber pad.

[0107] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the guardrail 120 includes a main body 124, a mounting member 125 and a connecting member 126, wherein the main body 124 and the base 110 are enclosed to form a working chamber 130, and the mounting member 125 is arranged on the side of the main body 124 away from the working chamber 130, and along the height direction of the working chamber 130, the mounting member 125 includes a first end 127 and a second end 128 opposite to each other, and the first end 127 is farther away from the base 110 than the second end 128, and the first end 127 is provided with a mounting interface 121, and the connecting member 126 is wrapped around the outside of the first end 127 and / or the second end 128 for connecting the main body 124.

[0108] In this embodiment, the guardrail 120 is defined to include a main body 124, a mounting member 125 and a connecting member 126. Specifically, the mounting member 125 is arranged on a side of the main body 124 away from the working bin 130, and along the height direction of the working bin 130, the mounting member 125 includes a first end 127 and a second end 128. The first end 127 is farther away from the base 110 than the second end 128, that is, the first end 127 is the top end and the second end 128 is the bottom end.

[0109] The mounting interface 121 is arranged at the first end 127, that is, the mounting interface 121 is arranged at the top of the mounting member 125. When the functional component 140 is connected to the mounting interface 121, the functional component 140 can be installed on the top of the guardrail 120. Compared with the related art in which the stretcher support is arranged at the bottom of the working bucket 100 and the stretcher support is driven to extend or be retracted through a guide mechanism, the functional component 140 and the guardrail 120 can be quickly matched and installed to improve the rescue efficiency. In addition, the overall structure of the working bucket 100 is simple, which is conducive to improving the overall stability and reliability of the working bucket 100.

[0110] The connecting member 126 is wrapped around the outside of the first end 127. Alternatively, the connecting member 126 is wrapped around the outside of the second end 128. Alternatively, the outside of the first end 127 and the outside of the second end 128 respectively wrap the connecting member 126. The connecting member 126 is connected to the body 124, that is, the mounting member 125 is reliably connected to the body 124 through the connecting member 126.

[0111] In some embodiments, optionally, the body 124 is an aluminum body, the connecting member 126 is an aluminum member; and / or the mounting member 125 is a steel member.

[0112] In this embodiment, the body 124 is defined as an aluminum body, and optionally, the body 124 is welded from a high-strength aluminum alloy pipe. The connector 126 is an aluminum part, that is, the material of the connector 126 is the same as that of the body 124, and optionally, a high-strength aluminum alloy round tube is wrapped at the top and / or bottom of the mounting part 125. Since the material of the connector 126 is the same as that of the body 124, it is convenient to reliably fix the connector 126 to the body 124 by welding.

[0113] In addition, since the main body 124 is made of aluminum, it is helpful to reduce the overall mass of the working bucket 100, thereby helping to reduce the overturning moment of the fire truck with the working bucket 100 and improve the stability and reliability of the fire truck during the rescue process.

[0114] The mounting member 125 is a steel member, so that the mounting member 125 has a certain structural strength, ensuring the effective matching connection between the mounting member 125 and the functional component 140, and improving the overall stability and reliability of the working bucket 100. Optionally, the mounting member 125 is a steel pipe.

[0115] like Figure 1 , Figure 3 , Figure 4 and Fig. 9 As shown, in some embodiments, optionally, the base 110 includes a base body 111 and a walkway assembly 112, wherein the walkway assembly 112 is disposed on the base body 111, the guardrail 120 is connected to the walkway assembly 112, and is enclosed with the walkway assembly 112 to form a working chamber 130; the base body 111 is a steel part, and the walkway assembly 112 is an aluminum component.

[0116] In this embodiment, the base 110 is defined to include a base body 111 and a walkway assembly 112 . Specifically, the walkway assembly 112 is disposed on the base body 111 , and the guardrail 120 and the walkway assembly 112 are enclosed to form a working chamber 130 .

[0117] The seat body 111 is a steel part, that is, the seat body 111 is welded as a whole from steel materials, thereby providing reliable support for the structural strength of the working bucket 100 and improving the reliability during the rescue process.

[0118] The walkway assembly 112 is an aluminum assembly, that is, the walkway assembly 112 is welded from high-strength aluminum alloy profiles, thereby ensuring the overall structural strength of the working bucket 100 while reducing the overall mass of the working bucket 100, which is beneficial to reducing the overturning moment of the fire truck with the working bucket 100 and improving the stability and reliability of the fire truck during the rescue process.

[0119] In a specific embodiment, Figure 4 As shown, a steel pipe (mounting member 125) is welded to the right side of the steel base (base 110) of the working bucket 100, and the top (first end 127) and bottom (second end 128) of the steel pipe are wrapped by a high-strength aluminum alloy round pipe (connecting member 126) and are integrally welded with the guardrail 120. Figure 5 As shown, a locking pin 151 (second locking portion 150) and a rubber pad (buffer 180) and other locking and buffering devices are installed at the top of the steel pipe. When the stretcher support (stretcher assembly 141) is installed on the top of the guardrail 120 of the working bucket 100, the rotating shaft (rotating member 143) below the stretcher support is inserted into the steel pipe. Since a pin hole (first locking portion 144) is opened on the rotating shaft, when the locking pin 151 is aligned with the pin hole, the rotating shaft 143 is rotated. Figure 5 The locking pin 151 in the stretcher can be locked and limited. Figure 1 and Figure 2 As shown. Since there is a clearance fit between the rotating shaft and the steel pipe, the clearance is small, so the locking method is safe and reliable. During rescue, when the injured person cannot walk, a stretcher can be used to transfer the injured person, and the stretcher is then fixed on the stretcher support (stretcher assembly 141), thereby completing the transfer and rescue of the injured person.

[0120] Similarly, when the hydraulic winch fixing seat (hoisting assembly 142) is installed on the top of the guardrail 120 of the working bucket 100, the rotating shaft (rotating member 143) below the hydraulic winch fixing seat is inserted into the steel pipe (installing member 125). Since the rotating shaft (the size is the same as the rotating shaft of the stretcher support (stretcher assembly 141)) is also provided with a pin shaft hole (first locking portion 144), when the locking pin 151 (second locking portion 150) is aligned with the pin shaft hole, the locking pin 151 is rotated at this time to lock and limit the hydraulic winch fixing seat, as shown in the specific example. Figure 3 As shown, the limit locking method is Figure 2 In the rescue process, when it is necessary to hoist rescue tools or other items from the ground to the working bucket 100 or to lower rescue tools or other items from the working bucket 100 to the ground, the hydraulic winch can be used to hoist them.

[0121] like Figure 7As shown, when the rescued person enters the working bucket 100 in a wheelchair (rescue device), the handrail 170 at the long pedal can be in a fully open state upward to facilitate the wheelchair to enter. The handrail 170 at the long pedal is in a fully closed state as shown in FIG. Figure 3 When the wheelchair enters the working bucket 100, a safety belt fixing device (safety belt assembly 160) is provided on the bottom frame walkway (walkway assembly 112), including a safety belt fixing seat and a safety belt (4 locations in total). The safety belt adopts a commonly used two-point safety belt, and the safety belt has a male plug (first plug-in portion 163) and a female plug (second plug-in portion 164). Figure 6 As shown, the wheelchair can be effectively fixed. Therefore, the working bucket 100 has multiple functions such as stretcher rescue, hydraulic winch lifting and wheelchair fixing.
