Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing:

[0020] figure 1 Shown is the overall structure diagram, and the connection relationship of each part must be correct and the installation should be firm.

[0021] The lifting frame is installed on the lifting quick-change mechanism of the utility vehicle, the up and down lifting is completed by the lifting mechanism of the utility vehicle, and the left and right steering is completed by the steering cylinder.

[0022] The lifting frame is connected with the boom through the arm cylinder and the arm shaft, and the boom is connected with the lifting arm through the installation cylinder and the installation shaft.

[0023] figure 2 As shown, it is the structural diagram of the lifting frame, which is the upper and lower parts. It must be strong and powerful. The steering cylinder, hinged seat, and hinged frame must be firm. The arm shaft must be strong. go to jail.

Abstract

The invention relates to a bracket crane of a multi-purpose underground coal vehicle, which consists of a hoist frame, a crane boom, a lifting arm, a steering cylinder, locating rods, a lifting ring, a rack groove, an installing drum, an installing axel, an arm axel, an installing rack, a fixing axel, a protecting panel, a fixing rack, an axel rack, an articulating rack and an articulating support. The hoist frame is provided with the left-right steering cylinder with the left-right steering half-angle of 45 degrees, the locating rods are respectively arranged at the left side and the right side of the crane boom to cause the crane boom to be limited and positioned and assure security. The fixing rack, the rack groove and the lifting ring are respectively arranged on the crane boom and the lifting arm so as to hoist materials, brackets, steel beams, cables and the like. The maximum loading capacity is 2,500 Kg. The hoist frame has reasonable design, impact structure, easy operation and use, safety, stability and reliability, thus the bracket crane is the ideal bracket crane of the multi-purpose underground coal vehicle.

Description

technical field [0001] The invention relates to a cantilever crane of a multifunctional vehicle in underground coal mines, and belongs to the technical field of design and manufacture of spare parts for auxiliary transportation equipment in underground coal mines. Background technique [0002] Underground coal mine is a narrow space for mining and transportation. Coal mining operations, handling, lifting, and transportation are all subject to great restrictions, which seriously restricts coal mining and transportation. [0003] Under the coal mine, there are often some materials, tools, pipe networks, auxiliary materials, etc. that need to be hoisted, moved, and transported, and some brackets, steel beams, and small equipment need to be installed, disassembled, and repaired. Most of the small lifting equipment used can only rely on manpower and simple tools to carry out these tasks at present, which is inefficient, labor-intensive, and not safe enough.
