[0002] The clamping type logistics shelf shuttle (hereinafter referred to as the shuttle) is a device capable of moving in an automated stereoscopic warehouse. When the shuttle moves to a preset position of the stereoscopic warehouse, the shuttle can drive two oppositely arranged clamping arms to synchronously extend or synchronously retract, so as to push the articles located on one side of the two sides of the shuttle through the abutting blocks on the clamping arms. However, the inventors found through research on the existing shuttle that the existing shuttle has the following problems: 1. The shuttle needs to be provided with two driving members to correspondingly drive the two clamping arms to move, and the provision of the two driving members increases the production cost of the shuttle; 2. The movable extension amount of the clamping arm is small, so the shuttle is difficult to remove articles with a long size. SUMMARY

One mounting arm, one extension arm and one clamping arm which are sequentially arranged in sliding manner are all connected with one linkage assembly. The transmission assembly is arranged in the vehicle body. Two extension arms are both connected with the transmission assembly. The second driving member is arranged in the vehicle body. The second driving member is connected with the transmission assembly. The second driving member can drive two extension arms to synchronously move left or right through the transmission assembly. The extension arm which moves left or right can drive the corresponding clamping arm to move left or right through the linkage assembly.

[0005] The clamping type logistics shelf shuttle according to an embodiment of the present application has at least the following beneficial effects:

[0006] When the shuttle moves to a preset position of the stereoscopic warehouse, the process of the shuttle removing the articles located on one side of the left and right sides of the shuttle is described by taking the removal of the articles on the left side as an example (with reference to Figure 1):1、 two first driving members located at the left end drive the two abutting blocks thereon to rotate to the avoiding state; 2、 the second driving member drives the two extension arms to move left synchronously through the transmission assembly, at this time, the two extension arms moving left synchronously drive the two embracing arms thereon to move left further through the two linkage assemblies, so that the two abutting blocks located at the left end and in the avoiding state are moved to the left side of the article; 3、 the two first driving members located at the left end drive the two abutting blocks thereon to rotate to the pushing state; 4、 the second driving member drives the two extension arms to move right synchronously through the transmission assembly, at this time, the two extension arms moving right synchronously drive the two embracing arms thereon to move right further through the two linkage assemblies, so that the two abutting blocks located at the left end and in the pushing state push the article between the two embracing arms to move to the storage plate.
