Description

Modularized large-diameter sleeve transferring device Technical Field The utility model relates to the technical field of underground rescue equipment, in particular to a modularized large-diameter sleeve transferring device. Background The horizontal rescue drilling machine is important rescue equipment for rapidly opening a horizontal rescue escape passage after the engineering collapses, drilling is realized by adopting a sleeve drilling and screw shaft deslagging mode, finally the screw shaft is pulled out to leave the sleeve in the collapse body to form the escape passage, secondary collapse and secondary injury caused in the drilling process can be effectively reduced, and the horizontal rescue drilling machine is the coal mine and tunnel engineering collapse mechanized rescue equipment which is the safest, reliable and efficient at present. The diameter of a drilling tool (the drilling tool is cylindrical and is also suitable for a sleeve and a screw shaft) used for the horizontal rescue drilling machine is usually larger than 600mm, the length of each section is larger than 1m, and the weight of each section is larger than 1t. Because tens of drilling tools are generally required for single rescue construction, the method is limited by the transportation conditions of coal mines and tunnels, and how to transfer a plurality of drilling tools below a vehicle-mounted cantilever of a horizontal rescue drilling machine becomes an important factor affecting the comprehensive efficiency of rescue construction. When the horizontal rescue drilling machine reaches a rescue construction site, general mechanized equipment cannot turn around between the horizontal rescue drilling machine and the contour of the roadway due to the influence of the size of the roadway, and only a small trailer is manually pulled to transport the drilling tool in a reciprocating mode, so that the labor intensity is high and the transportation efficiency is low. Disclosure of utility model The utility model aims to provide a modularized large-diameter casing pipe transferring device, which solves the technical problem that in the prior art, a drilling tool (casing pipe) is inconvenient to transport when horizontal rescue construction is carried out, and the specific technical scheme is as follows: The utility model provides a modularized large-diameter sleeve transferring device which comprises a transferring frame and two groups of carrier roller assemblies, wherein the two sides of the transferring frame are higher than the middle part, the width of the transferring frame is not smaller than the radius of a sleeve, the two groups of carrier roller assemblies are arranged in the transferring frame in a V shape, each group of carrier roller assemblies comprises a plurality of carrier rollers, and the carrier rollers are arranged on the transferring frame at intervals in a rotatable mode. The modular large-diameter sleeve transferring device is further improved in that the transferring frame comprises a bottom frame and two vertical frames, and the two vertical frames are fixed on two sides of the bottom frame. The modular large-diameter sleeve transferring device is further improved in that diagonal braces are fixed between the vertical frame and the underframe. The modular large-diameter sleeve transferring device is further improved in that a plurality of first clamping plates for mounting the carrier roller are fixed on the vertical frame. The modular large-diameter sleeve transferring device is further improved in that a plurality of second clamping plates for mounting the carrier roller are fixed at the middle position of the underframe. The modular large-diameter sleeve transferring device is further improved in that the convex strips for fixing the second clamping plates are arranged on the underframe. The modular large-diameter sleeve transferring device is further improved in that the carrier roller comprises a rotating shaft, a bearing and a roller body, wherein the bearing is arranged on the rotating shaft, the roller body is arranged on the bearing, and the rotating shaft is arranged on the first clamping plate and the second clamping plate. The modular large-diameter sleeve transferring device is further improved in that connecting flanges are arranged at two ends of the transferring frame. The technical scheme of the utility model has the following beneficial effects: According to the modularized large-diameter sleeve transferring device, the sleeve is placed on the carrier rollers which are arranged in a V shape, so that the sleeve can be moved and transported on the carrier rollers, and the technical problem that the sleeve is inconvenient to transport when horizontal rescue construction is carried out in the prior art is solved.
