Description

Flexible pipe that rock drilling equipment is used and cable reel arrangement

The present invention relates to a kind of flexible pipe and cable reel arrangement that is used for rock drilling equipment, it comprises at least two reels that are installed in the rock drilling equipment, so that rotate with mutual with respect to the framework rotation of this equipment.A reel is for a flexible pipe and/or cable usefulness, and the wheel word of each reel is used to make above-mentioned reel to rotate with respect to framework.

A rock drilling equipment, its need of work is supplied with its electric energy and is supplied with sparge water or air by a kind of water or air hose by cable.Cable is normally coiled on the independently cable reel on the equipment of being installed in; And, there is no need to install reel, but by artificial or assemble and in place by a manually-operated water tube hose reel for water tube hose.Also may be with the cable and the hose reel of an associating, be provided with on this reel independently that the space is used for cable and flexible pipe, and this reel is to be attached to a fixing integral body on the independent reel framework with bearing, this framework is fixed on the carrying tool of equipment.Know in addition, with two parallel installings and the independent reel that rotates around horizontal shaft.In this case, two reels have independently framework structure and the corresponding independent rotation mechanism on the carrying tool that is fixed to drilling equipment.

The shortcoming of prior art is when the reel of installing only is used for cable, and heap send flexible pipe heavy, and difficulty is time-consuming again, and this affects the time schedule that creeps into and unavoidably loses time.

When the reel that separates with two, also need two framework structures of separating, this can increase the complexity of cost and structure.And coil flexible pipe by hand is that very heavyization is time taking.Moreover, if only use a reel, have to the design of the framework structure of drilling equipment and be retrofit into be used for a reel, be with two kinds of different framework structures thereby same drilling equipment must be processed as.With two reels that separate, framework structure need have abundant space, and this has increased the overall dimension of drilling equipment, so make its mobility variation in the tunnel.

The shortcoming of two shared single fixedly spool structure of flexible pipe is that electricity and water feeder normally are arranged on the difference place in the tunnel.In order to be provided for the enough cables and the hose length of longer distance, therefore cable and flexible pipe have to unclamp a kind of like this length of long distance needs, and be respectively applied for more short-range remaining cable or hose length, must spread out on the ground in tunnel.If flexible pipe and cable are unclamped, the long distance bundle of flexible pipe extend through is tied on its attachment point, need more short-range flexible pipe or cable will inevitably be entangled on the reel, untie from structure, relate to overwork and problem and elapsed time.

The CA patent discloses the scheme of a solution No. 1213870, and wherein, cable is coiled round the tabular pedestal that rotates and be arranged on the equipment around heavy d-axis.The deficiency of this solution is that the above device occupation space of drilling equipment can not be used for any other purpose, and because dirt, rubble and the stone that drops, cable and flexible pipe easily are damaged.

The purpose of this invention is to provide a kind of be used for cable and hose reel twisted on the reel install, this method will be avoided by the problems referred to above and flexible pipe and cable can be coiled independent of one another.Another object of the present invention provides a reel erecting device, and this device can be installed one or two reels in the same framework structure of equipment, and makes flexible pipe and/or cable avoid damaging with this device, and needs less space in the equipment frame.According to the present invention, this is by under the framework of drilling equipment the mutual overlapping coaxially installation of several reels being realized, so that rotate around vertical axis.

Basic idea of the present invention is that the reel that is used for cable and/or flexible pipe is to be installed in below the framework of drilling equipment, so that rotate with one heart but independently of one another around a vertical axis, like this, each reel can rotate and irrelevant with other reel by an independent rotation motor.According to solution of the present invention, its advantage is, owing to reel is installed in below the drilling equipment, so exempt from the damage of rubble, dirt and falling rocks.Another reconnaissance of the present invention is that reel needs the space outerpace of drilling equipment less, thereby has reduced the outside dimension of equipment, and equipment can be processed into suitable back taper, so that it moves in the tunnel is more convenient.Advantage in addition of the present invention is that reel can constitute like this: one or two reel can need to be installed in the bottom of means of delivery as the case may be, and need not framework structure is transformed.In addition, no matter, can use same framework structure, so this solution is cheap than the solution of prior art because be with one or with two reels.By the present invention, because flexible pipe and cable can unclamp and coil independently, just can keep the tightness of cable and flexible pipe is the steady state value that requires, and does not consider the position of flexible pipe or the cable attachment point in the tunnel.The machinery of other that need in drilling equipment and equipment for the space that utilizes drilling equipment to use rightly, can be arranged on the reel top on the framework of drilling equipment.

To quite at length be described herein in the accompanying drawing below the present invention, wherein:
