[0031] The following Figures 1-4 Describe the attachment quick-change system of the embodiments of the present invention. The attachment quick-change system includes an attachment quick coupler 100 and an attachment mount 200. A first docking surface 110 is formed on the attachment quick coupler 100, and a second docking surface 210 is formed on the attachment mount 200. The first docking surface 110 and the second docking surface 210 are disposed opposite to each other.

[0032] A first quick plug 120 is disposed on the first docking surface 110, and a second quick plug 220 is disposed on the second docking surface 210. The first quick plug 120 is one of a male plug interface and a female plug interface of a hydraulic power oil circuit, and the second quick plug 220 is the other of the male plug interface and the female plug interface of the hydraulic power oil circuit. When the first quick plug 120 and the second quick plug 220 are docked, the oil circuit connection between the working arm and the attachment can be realized.

[0033] The first quick plug-in 120 is perpendicular to the first docking surface 110, and the second quick plug-in 220 is perpendicular to the second docking surface 210. The first quick plug-in 120 and the second quick plug-in 220 are plugged in along the direction perpendicular to the first docking surface 110. Thus, during the docking process of the attachment quick connector 100 and the attachment installer 200, the docking of the first quick plug-in 120 and the second quick plug-in 220 can be directly completed, which is convenient to operate and has relatively low requirements for the operator.

[0034] The attachment installer 200 is further provided with a positioning plate 230. The positioning plate 230 is perpendicular to the second docking surface 210. A positioning chute 231 is formed on the positioning plate 230. The positioning chute 231 is a V-shaped groove, and the opening of the positioning chute 231 faces away from the second docking surface 210. The attachment quick connector 100 is provided with a limiting member 140, and the limiting member 140 is located at the bottom of the positioning chute 231. During the docking process of the first quick plug-in 120 and the second quick plug-in 220, the inclined side walls of the positioning chute 231 can play a guiding role for the limiting member 140, making the docking of the attachment quick connector 100 and the attachment installer 200 and the docking of the first quick plug-in 120 and the second quick plug-in 220 more accurate and smooth.

[0035] In an embodiment of the present invention, a first clamping member 130 and a driving device are provided on the first docking surface 110, a second clamping member 240 is provided on the second docking surface 210, the driving device is connected to the first clamping member 130, and the driving device is adapted to drive the first clamping member 130 to move along the first docking surface 110 to dock or disengage the first clamping member 130 and the second clamping member 240. When the first clamping member 130 and the second clamping member 240 are docked, the attachment quick connector 100 and the attachment installer 200 are connected and fixed, completing the docking of the working arm and the working attachment, and at the same time restricting the first quick plug-in 120 and the second quick plug-in 220 to prevent the first quick plug-in 120 and the second quick plug-in 220 from disengaging.

[0036] Optionally, the driving device includes a first driving member 300 and a second driving member 400. The first driving member 300 and the second driving member 400 face in opposite directions and are both parallel to the first docking surface 110. First engaging members 130 are respectively provided on the first driving member 300 and the second driving member 400. The first driving member 300 and the second driving member 400 can respectively drive the first engaging members 130 to move. Moreover, the moving directions of the first engaging members 130 on the first driving member 300 and the first engaging members 130 on the second driving member 400 are opposite. Two second engaging members 240 corresponding to the first engaging members 130 on the first driving member 300 and the first engaging members 130 on the second driving member 400 are respectively provided on the second docking surface 210. The first driving member 300 can drive the first engaging member 130 on the first driving member 300 to dock with or disengage from its corresponding second engaging member 240, and the second driving member 400 can drive the first engaging member 130 on the second driving member 400 to dock with or disengage from its corresponding second engaging member 240. Thus, when the attachment quick coupler 100 and the attachment installer 200 are connected, the connection between the attachment quick coupler 100 and the attachment installer 200 can be made more firm and stable through limiting in opposite directions.

[0037] Optionally, at least one of the first driving member 300 and the second driving member 400 is a telescopic oil cylinder. By telescoping in a direction parallel to the first docking surface 110, the movement of the first engaging member 130 is realized.

[0038] Optionally, a pressure sensor 500 is provided on the telescopic oil cylinder. The pressure sensor 500 is used to detect the oil pressure in the telescopic oil cylinder. Whether the first engaging member 130 and the second engaging member 240 are connected can be determined by the oil pressure in the telescopic oil cylinder. Connecting the pressure sensor 500 to the control system of the telescopic oil cylinder can form a feedback, providing conditions for the automatic or semi-automatic control of the attachment quick connection system.

[0039] In an optional manner of the present invention, the limiting member 140 is a roller fixedly provided on the attachment quick coupler. The axial direction of the roller is perpendicular to the positioning plate 230, and its diameter is the same as the width of the bottom of the positioning chute 231. Optionally, a set of the positioning plate 230 and the positioning chute 231 are provided on each side of the attachment installer 200, and two limiting members 140 are correspondingly provided for the positioning chute 231, achieving the purpose of more accurate positioning.

[0040] Optionally, the first snap member 130 is a hook with an opening facing the second snap member 240, and the second snap member 240 is a connecting pin shaft arranged in parallel on the second docking surface 210. The connecting pin shaft can be supported and fixed by a support seat to form a gap between it and the second docking surface 210. When the driving device drives the hook to move to be hooked with the connecting pin shaft, a reverse limit is formed between the two first snap members 130 in different directions and the two second snap members 240, which can tightly combine the attachment quick coupler 100 and the attachment mount 200. It can be understood that when the first snap member 130 adopts a pin shaft structure and the second snap member 240 adopts a hook structure, the connection between the attachment quick coupler 100 and the attachment mount 200 can also be achieved, and it should also be within the protection scope of the present invention.

[0041] Optionally, a feedback element 600 is arranged on the positioning chute 231. The feedback element 600 can be specifically arranged on one side of the bottom of the positioning chute 231 for detecting the on-off state of the first quick plug-in 120 and the second quick plug-in 220 to form feedback. The feedback element 600 can specifically adopt a limit switch or a proximity switch.

[0042] In an embodiment of the present invention, a rescue device is provided, including a working arm, an operating attachment, and the attachment quick connection system described in any one of the above. The attachment quick coupler 100 in the attachment quick connection system is arranged at the end of the working arm, and the attachment mount 200 is arranged on the operating attachment. When the working arm moves to align with the operating attachment and the attachment quick coupler 100 on the working arm moves towards the attachment mount 200 on the operating attachment, the first snap member 130 can be connected to the second snap member 240, and the first quick plug-in 120 and the second quick plug-in 220 are docked, simultaneously realizing the connection between the working arm and the operating attachment and the connection of the oil circuit on the working arm and the oil circuit on the operating attachment. The rescue device with such a structure can simplify the installation process, reduce the requirements for the operator, improve the attachment replacement efficiency, and save a large amount of precious time for emergency rescue.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
