The specific embodiment
As shown in Figure 1: the support of combination type drilling machine is welded by two vertical beams 7 and 14,6,8,9 and 4 connecting plates 15 of crossbeam, the present invention recommends the combination type drilling machine that uses, between the place ahead of base crossbeam 14 and crossbeam 13, clamp 12 drill tool assemblies 3, there are 9 motors 5 that are installed on the base to drive drill bit rotation drilling respectively, two drilling tool work of every driven by motor of three motors are wherein arranged by belt 4 and belt pulley.The installation of drilling tool is clamped in drilling tool between crossbeam 13 and the crossbeam 14 by four locking wheels 10, and as required, the position between the drilling tool can be adjusted arbitrarily.Tension pulley all is installed in order to adjust the elasticity of belt on the every belt.
As shown in Figure 1, the walking mechanism of combination type drilling machine is achieved in that and on the connecting plate 15 at two ends, the left and right sides, front end bottom of base the near front wheel 12 is installed respectively and 18, two front-wheels of off-front wheel are universal wheel.Two trailing wheels 25 are fixed on the two ends of power transmission shaft 27, and power transmission shaft 27 is installed on two vertical beams 7 by bearing block 26 and can freely rotates.The gearbox 20 that is installed in the movable motor 21 on the base and is attached thereto is meshed by the gear 23 of on the output shaft of gear-box gear 22 being installed and be installed in the transmission 27, transmission of power to power transmission shaft 27, is driven trailing wheel 25 rotations and makes combination type drilling machine advance, retreat.
As shown in Figure 2, the drilling function of rig is realized with following scheme: the rectangle fixed head 33 of drill tool assembly 3 upper ends is fixed on the upper end of cylindrical jacket pipe 35 by screw 34, and last inner sleeve 44 circumference are connected with the inner hole wall of outer tube 35 also by two bearings 38 that energy freely rotate; Last inner sleeve center makes splined hole, is connected with the spline of main shaft 42 upper ends in being through splined hole; Belt pulley 32 is tightly fixed at the topmost of last inner sleeve 44, and motor 5 drives by belt 4 and goes up inner sleeve 44 together with main shaft 42 rotations; The lower end tight fit of main shaft 42 is installed drill chuck head 41, and drill bit 40 is installed on the drill chuck head 41; The excircle sliding fit of following inner sleeve 37 is installed in the bottom endoporus of outer tube 35, and upper and lower fixing plate 36,39 is connected with following interior cover 37 upper and lower sides by screw, and shaft block ring 43 is installed in the upper and lower fixing plate outside respectively.
As shown in Figure 3, drill bit is realized with following scheme to feed function: make tooth bar 47 on the plane of following inner sleeve 37 middle part cylindrical generatrix direction millings and be meshed with gear 57 on the installation shaft 48; Axle 48 two ends are connected with fixed mount 50 by two bearings 51, and fixed mount is installed on the crossbeam 14; Being installed in the another gear 49 of axle on 48 is meshed with gear 52 on being installed in power transmission shaft 46; The two ends of power transmission shaft 46 are connected with vertical beam 7 by bearing block 45.
As shown in Figure 3, Figure 4, the piston rod of rack-mounted cylinder 56 and tooth bar 54 hinge joints, tooth bar 54 is installed on the guide rail 55 and with gear 53 and is meshed, and guide rail 55 is fixed on the frame.When cylinder operation, promote tooth bar 54 and move, again by gear 53,52,49,57, in gear 57 and the drill tool assembly down tooth bar 47 engagements on inner sleeve 37 outer circumference surfaces drive drill bits and move up and down the feeding that realizes drill bit and withdraw from.A gear 57 and axle 48 sliding fits horizontally slip at the axis direction of the downward axle 48 of the effect of shift fork 58.When certain drill bit does not need work, promote shift fork 58 and make the drill bit of gear 57 disengaging tooth bars 47 these drilling tools only rotate not feeding.
As shown in Figure 1, the quantity of described drill tool assembly 3 and position are determined according to the position in each gang drill hole of container bottom board.
As shown in Figure 3, Figure 4, all have one group of drilling feed system supporting with it on described each drill tool assembly 3, these feed system power are all provided by power transmission shaft 46, reach whole drill bit synchro-feed borings.
As shown in Figure 1, the guide function of way-type drilling unit when container moves is achieved in that because the container side plate is a corrugated steel plate, air spots, the guiding belt 24 of belt guidance set 2 is a closed loop, driving wheel and deflecting roller and middle some rollers are installed on the belt support respectively and can rotate, and belt holder is fixed on the frame both sides; The diameter of deflecting roller is less than roller and driving wheel; Help combination type drilling machine like this and enter container.Two coaxial mounted sector gears of driving wheel are meshed with the sector gear that install at power transmission shaft 31 two ends respectively, power transmission shaft 31, the middle part connect with power transmission shaft 27 by chain transmission 30.Adjust the chain transmission speed ratio linear velocity of trailing wheel 25 is equated with the linear velocity of belt in the belt guidance set, thereby the guiding belt is not slided on boxboard, guarantee guiding accuracy.
As shown in Figure 1, the brake gear of combined driller for machining container bottom plate is by power transmission shaft 27 middle parts brake assemblies 29 to be installed, and the operator is sitting on the seat 17 can operate switch board 16 and brake lever 19 easily.
When combination type drilling machine before centering bore position boring, operation brake handle 19 is checked trailing wheel 25 and is not allowed its rotation, drill bit swing when avoiding drilling and influence drilling quality.
The power line of combination type drilling machine is installed in the elasticity winding box 28 at base rear portion, avoids the exposed electric leakage accident that causes of power line.
As shown in Figure 5, elevator comprises frame 59, wheel 63 and leg 64 compositions, the position of the fixed dam 60 restriction combination type drilling machines 61 of frame 59 rear sides, the safety when guaranteeing the elevator motion.The wheelspan of four front and back wheels of distance and combination type drilling machine of two guide rails 71 that install on frame 59 tops equates, the rotary rail 68 that the front and back wheel 12,18,25 of combination type drilling machine 61 is put into guide rail 71 and two guide rail hinge joints makes it to fall and is overlapped on the container bottom board by operation cylinder 70 when rig passes in and out, and rig 61 prolongs rotary rail 68 and enters in the container.This moment, supporting leg 69 played the effect of supporting rotary rail 68, finished retreating on the elevator when rig 61 work, and operation cylinder 70 makes rotary rail 68 and vehicle frame 59 vertical, together played with fixed dam 60 and blocked rig and can not move on elevator.The motion of elevator is driven by motor 67 and chain transmission 66.Four supporting legs 64 of both sides are regulated the horizontal level with container when rig turnover container, and play supporting role, and supporting leg 64 is regained during the elevator walking.
