Embodiment Construction

[0028] Depend on Figure 1-Figure 3 The folding hydraulic lifting equipment shown includes a lifting frame and an auxiliary folding device. The lifting frame includes a left upper beam 3, a left top beam 1, a right top beam 2 and a right upper beam 4 hinged from left to right in turn, and the left upper beam 3, left The roof beam 1, the right roof beam 2 and the right upper beam 4 all extend forward and backward. Page 28 is hinged, and the right end of left top beam 1 is fixedly connected with the left end of right top beam 2 by the stud 27 that is positioned at movable hinge 28 lower sides, and during folded state, double end stud 27 withdraws, and left top beam 1 and the right top beam 2 can be folded into a "V" shape angle. When in an extended state, the stud 27 is fixedly connected to the left top beam 1 and the right top beam 2 so that the two cannot be folded. The right end of the right top beam 2 and the right upper beam 4 The top left end is hinged.

Abstract

The invention discloses a folding type hydraulic hoisting device which comprises a hoisting bracket. The hoisting bracket comprises a left upper beam, a left top beam, a right top beam and a right upper beam which are sequentially hinged from left to right, the lower side of the left upper beam and the lower side of the right upper beam are respectively provided with a vertical supporting hydraulic cylinder and two height-adjustable supporting columns arranged in a front-back mode, oblique supporting assemblies are respectively arranged between the left upper beam and the left top beam and between the right upper beam and the right top beam, bilaterally symmetric and oblique supporting rods and obliquely-arranged oblique pulling hydraulic cylinders, and the left top beam and / or the right top beam is provided with a lifting device with a hook. The folding type hydraulic hoisting device is used for assembling and disassembling the hydraulic devices which are high in automation degree, safe, reliable and good in applicability.

Description

technical field [0001] The invention belongs to the field of mining machinery manufacturing and application, and in particular relates to hydraulic lifting equipment for mines, which can assemble and disassemble equipment for fully mechanized mining equipment of different types underground. Background technique [0002] Mine hydraulic lifting equipment is the equipment for the disassembly and assembly of different types of fully mechanized mining equipment in mines, especially for the disassembly and assembly of hydraulic supports. The hydraulic support is the supporting equipment of the mine working face. The hydraulic support is disassembled before entering the well. After entering the well, it is assembled in the chamber, and after assembly, it is transported to the working face. [0003] At present, the weight of hydraulic supports used in coal mines is mostly about 10-30t, which plays a role in supporting the roof of coal mines. Below it is the coal mining unit, and th...
