[0001] The utility model relates to the technical field of coal mining auxiliary equipment, in particular to a vertical lifting vehicle mounting device for a fully mechanized mining support. Background Art

[0002] The vertical lifting and loading device of the comprehensive mining support is an auxiliary equipment used in coal mining. During the mining operation, in order to facilitate the advancement of the mining face, the vertical lifting and loading device of the comprehensive mining support is generally dismantled or moved to facilitate the subsequent mining operations. However, there are still some problems with the existing vertical lifting and loading device of the comprehensive mining support. For example, as proposed in the prior art application: CN202023030280.0, although the stability between the transportation device and the integral support can be increased by connecting them to the protrusion through a slot, the transportation device will still shake, displace, or even fall off when moving up and down, which has certain safety hazards and cannot effectively clamp and fix the transportation device. For this reason, we propose a vertical lifting and loading device for a comprehensive mining support. Utility Model Content
