Described mark position comprise for the dark highly corresponding descending mark position of the brill of the unit head of mast front side and for the unit head of mast rear side put forward the highly corresponding up mark position of brill.
The technical scheme of the dark control device of brill of long-spiral drilling machine of the present utility model is as follows:
The dark control device of the brill of long-spiral drilling machine, comprise for the induction unit head move to the marked locations of mast limit switch, be used for being serially connected in break-make control branch road to control the relay contact switch that main motor relay contactor is switched on or switched off power supply, relay contact switch and limit switch control connection.
The utility model bores dark control device to control the brill of drilling rod dark and/or carry and bore height by setting up at long-spiral drilling machine, namely whether arrive marked locations on the mast by the limit switch induction unit head that bores dark control device, control main motor relay contactor by the relay contact switch and be switched on or switched off power supply, control master winch cylinder rotates, and the limit switch control connection is on the relay contactor switch, to reach limit switch and the coordination of relay contact switch, dark and/or put forward the purpose of boring height with the brill of finishing the Based Intelligent Control drilling rod, compared with prior art, need not manually-operated and just can finish the effect of creeping into and/or propose the brill parking, solved the brill of holing in the prior art and relied on Artificial Control to be easy to generate error deeply, caused and bore deeply inadequately or put forward the too high problem of boring.

The specific embodiment
The embodiment of long-spiral drilling machine of the present utility model: extremely shown in Figure 5 as Fig. 2, this long-spiral drilling machine comprises the mast 21 that extends up and down, the movable pulley frame 22 and the unit head 23 that lead and assemble along the vertical direction respectively in the both sides, front and back of mast 21, the reel control module 24 that is used for the elevator action of control master winch cylinder, bore dark control device, wherein below mast 21 has the movable pulley that is in its rear side and the mark position below the unit head 23 of its front side, mark position corresponding unit head 23 in front side bores the correspondence position of dark height, and the corresponding unit head 23 of rear side mark position is carried the correspondence position that bores height.Be provided with in the reel control module for when connecting power supply, making the elevator motor M connect power drives master winch cylinder and rotate, make elevator motor M deenergization during at deenergization and make the main motor relay contactor KM2 that the master winch cylinder stops operating and be used for the break-make control branch road that the main motor relay contactor KM2 of control is switched on or switched off power supply.Bore dark control device and comprise that two are located at the limit switch 25 of front side mark position and rear side mark position on the mast 21 respectively and are used for being serially connected in break-make control branch road to control relay contact K switch A1, the KA2 that main motor relay contactor KM2 is switched on or switched off power supply, relay contact K switch A1, KA2 are serially connected in the control circuit of reel control module 24 successively, with being switched on or switched off, reaching and control the purpose that main motor relay contactor KM2 is switched on or switched off power supply by control break-make control branch road and power supply.
Present embodiment in use, discharge cock SB1 connection, branch switch SB2 or KM1 connection in the break-make control branch road, the constant close contact of relay contact K switch A1, KA2 are connected, then main motor relay contactor KM2 connects power supply, and main motor M can drive the elevator cylinder and rotate.When limit switch 25 actions, relay contact K switch A1, KA2 disconnect, main motor relay contactor KM2 also disconnects thereupon, the stall of master winch cylinder, namely when unit head 23 or movable pulley when mast 21 moves down, unit head 23 and movable pulley frame 22 can touch limit switch 25, at this moment, limit switch 25 actions, the break-make that disconnects reel control module 24 is controlled branch road, makes the stall of master winch cylinder; Front side limit switch 25 prevents from boring the dark design load that surpasses, and after this limit switch 25 configures, transfers too much as unit head 23, and unit head 23 contacts with the induction handle, limit switch 25 actions, and the master winch cylinder stops operating; Rear side limit switch 25 prevents that unit head 23 from promoting superelevation, and after this limit switch 25 configured, too high as unit head 23 liftings, movable pulley frame 22 contacted with limit switch 25, limit switch 25 actions, and the master winch cylinder stops operating.Limit switch 25 is installed on mast 21 and goes forward on the connection gusset of rear slide, can be dark with the brill in different building sites, the position of limit switch 25 is regulated.By introducing the control loop of reel control module 24 with the constant close contact of relay contact K switch A1, the KA2 of limit switch 25 control connections, realize the control to the master winch cylinder.
In the above-described embodiments, preceding mark position is in the below of unit head on the mast, and back mark position is in the below of movable pulley frame on the mast, in other embodiments, mark position or back mark position before mark position also can only exist are with the dark height of the brill of only controlling drilling rod or carry and bore height; Perhaps mark position is set respectively and/or at the upper-lower position of mast rear side movable pulley frame mark position is set respectively at the above-below direction of mast front side unit head.
The embodiment of the dark control device of brill of long-spiral drilling machine of the present utility model: to shown in Figure 5, it is identical with the dark control device structure of the brill in above-described embodiment that this bores dark control device as Fig. 2, therefore repeats no more.
