Problems solved by technology

During the use of this equipment, there are the following disadvantages: 1. Due to the heavy weight of the front and rear conveyors and the middle tank, and limited by the width of the underground roadway, the width of the conveyor is limited, and the conveyor will be unstable during the lifting process; 2. Because the conveyor The size is too large and cannot be transported as a whole machine. It needs to be disassembled into parts and assembled underground, which is time-consuming, laborious, and inefficient. In addition, this equipment cannot allow the flatbed truck transporting the middle tank to pass through, so that every time it is transported to the middle tank, the flatbed truck must be pulled by the tractor immediately. The machine pulls the flatbed truck away, and then uses the flatbed truck to transport it to the middle slot of the next truck, which is less efficient

Abstract

The invention discloses a hydraulic crane for a middle trough. The hydraulic crane comprises frames, a crane jib, a crane jib liftingoil cylinder, a crane jib rotating oil cylinder and the like, wherein a supporting device is arranged on the two sides of each frame, a telescopic device is arranged between the frames on the two sides and comprises a frame telescopic cylinder at the bottom of the frame and a telescopic beam at the upper part of the frame. The hydraulic crane for the middle trough has the advantages that the horizontal size of the hydraulic crane for the middle trough is greatly reduced, so that the hydraulic crane for the middle trough can be conveniently transported on the ground and underground, the dismounting procedure is canceled, and the production efficiency is greatly improved. As a supporting structure is added, the stability of the crane is guaranteed when the middle trough is lifted; in addition, as the frame telescopic cylinder is connected with the frames through pin shafts, the frame telescopic cylinder is conveniently dismounted when the crane works, so that the workload is greatly reduced, and the efficiency is improved by several times.

Description
