The invention relates to a lifting device, in particular to the lifting device for a deep hole drill rig which is used in mine operations. The lifting device mainly solves the problems that drainage hole of the deep hole drill rig is single and height of drilling holes cannot be adjusted freely. According to the technical scheme, the lifting device comprises a cross beam, a first connecting rod, a second connecting rod, a support oil tank and the like. One end of the cross beam is hinged to a fixed seat through a hinge pin. The other end of the cross beam is connected with a lifting platform through a hinge pin. One end of the support oil tank is fixed to the fixed seat. The other end of the support oil tank is connected with the middle upper portion of the cross beam. One end of an adjusting oil tank is fixed to the fixed seat. The other end of the adjusting oil tank is connected with one end of the first connecting rod. The other end of the first connecting rod is connected with one end of the second connecting rod. The other end of the second connecting rod is connected with the lifting platform. The lifting device for the deep hole drill rig is simple in structure, can adjust lifting height freely, and is stable and flexible in operation.
Description
technical field [0001] The invention relates to a lifting mechanism, in particular to a lifting device used in mine operations for deep hole drilling vehicles. Background technique [0002] The deep hole drilling rig is a drilling rig used to control gas between coal seams and rock formations by means of drainage. Usually, the common problems of these deep hole drilling rigs in use are that the gas drainage hole is in a single position, the drilling height cannot be adjusted freely, and parallel drilling in soft coal seams and near-horizontal long-distance gas drainage drilling cannot be effectively performed. Contents of the invention [0003] The invention mainly aims at the problem that the deep-hole drilling rig has a single discharge hole and cannot freely adjust the drilling height, and provides a lifting device for the deep-hole drilling rig that can adjust the lifting height, operates smoothly, and is flexible. [0004] The technical scheme that the present invent...
