Description of drawings

Fig. 1 is the structural representation of a preferred embodiment of the utility model.

The specific embodiment

With reference to shown in Figure 1.The stone material retreading machine that the utility model discloses comprises the fuselage cradle 1 with fuselage base plate 2 and fuselage top board 3; And preposition Motorized lift device, be used to make the front end of stone material retreading machine to climb away the workbench surface or descend contact workbench surface, to be convenient for changing the mill 8 that is used to change the polishing building stones, wherein said workbench can adopt stone floor or adopt other forms, repeats no more here; And rearmounted hand-rail type machine level(l)ing device, the level height that is used to regulate machine makes mill 8 can require the certain plane requirement of maintenance according to polishing when the polishing building stones.

Below introducing the structure of the hand-rail type machine level(l)ing device of preposition Motorized lift device and postposition respectively forms with its operation principle.

Preposition Motorized lift device comprises: cover shell block 17, lifting motor 9 are fixed on the fuselage base plate 3, when lifting motor 9 rotates, because the turning cylinder of lifting motor 9 connects scroll bar 10, then scroll bar 10 rotates, scroll bar 10 rotates and drives turbine 11 rotations, turbine 11 has internal thread to entangle band keyway elevating screw 12, because of band keyway elevating screw 12 is blocked and can not rotate together with turbine 11 by latch 16, so band keyway elevating screw 12 together rises or descends together with universal wheel 15, changes the rotation direction of lifting motor 9 with this.In addition, be arranged at the upper stroke switch 13 of elevating screw 12 and lower stroke switch 14 and be the series connection energising, and what give that upper stroke switch 13 and lower stroke switch 14 provide circuit control power supply is the 24V low-tension supply that is provided by low-voltage electrical electric cabinet 19.And, upper stroke switch 13 is connected outage and the energising that an A.C. contactor is controlled lifting motor 9 with lower stroke switch 14, when lower limit stator 18 is run in the contact of the lower stroke switch 14 on the band keyway elevating screw 12, lifting motor 9 stops operating, the surface of universal wheel 15 contact workbenches 30, and force the machine front end to disengage workbench 30 and quilt act height; When screw mandrel upper limit stator 6 is run in upper stroke switch 13 contacts on the band keyway elevating screw 12, band keyway elevating screw 12 rises (or withdrawal) in fuselage, preposition electric turbine lowering or hoisting gear is finished one action, reached the purpose of my stone material retreading machine front end lifting, the purpose of stone material retreading machine front end lifting is that stone material retreading machine front end needs frequent loading and unloading mill 8 to change the needs that the abrasive disc of jack per line number is not realized the stone material renovation.

When the two-direction switch of lifting motor 9 being beaten to " rising " position, press " lifting energising " knob, band keyway elevating screw 12 begins to descend, the surface of universal wheel 15 contact workbenches 30; Machine is pushed up to when the height of settings earlier, and lower limit stator 18 is run in lower stroke switch 14 contacts on band keyway elevating screw 12 tops, and lifting motor 9 cut off the power supply immediately, and 12 declines of band keyway elevating screw stop, and the rising of machine front end stops; And mill 8 is put into turning cylinder 31 correspondence positions of machine front end.

And the two-direction switch of lifting motor 9 is beaten to " reduction " position, press " lifting energising " knob, band keyway elevating screw 12 begins to rise, universal wheel 15 also rises and disengages the surface of workbench 30, the front end of machine descends, machine turns axle 31 inserts mill 8 draw-in grooves, upper limit stator 6 is run in upper stroke switch 13 contacts on band keyway elevating screw 12 tops, lifting motor 9 cuts off the power supply immediately, band keyway elevating screw 12 rises and stops, the machine front end reduces and stops, and finishes the lifting of machine front end.

Because the stone material renovation work must be loaded and unloaded the mill number of times in one day countless, thus, the number of times of machine front end lifting is countless equally, this device is exactly to make countless manual operations change electric operating into, belongs to the domestic initiation of machinery equipment of the same type, and this device Hide All is in machine intimate, take very little space in the machine, the electrified control of easy to assemble, low pressure 24V has automatically the labour-saving advantage.

Hand-rail type machine level(l)ing device comprises: rocking arm 27 plug-in types are entangled dwang 28, dwang 28 is to be fixed on the fuselage top board 3 by fixed bearing block 29, dwang 28 and 45 degree small umbrella gears 26 are fixed, 45 degree small umbrella gears 26 and the 25 orthogonal and interlocks of 45 degree large umbrella gears.The big bevel type gear 25 of 45 degree is fixed with back screw mandrel 21, and back screw mandrel 21 is to be fixed on the fuselage top board 3 of fuselage cradle 1 by back screw mandrel shaft block 32; When rocking arm 27 rotates, back screw mandrel 21 and then rotates under the interlock of 45 two bevel gears 25 of degree size and 26 is rotated, and 21 rotations of back screw mandrel, can not move up and down, so entangling the slip silk braid 22 of back screw mandrel 21 slides, when slip silk braid 22 slides up and down, just drive by fixed pivot 24 fixing swing arms 23 and move up and down, because machine trailing wheel 20 contacts at workbench 30, thereby, the machine rear end can be heightened up and down and turn down, and reaches the purpose that machine rear end level is regulated, and machine rear end level is regulated the needs that mill when being stone material retreading machine mill ground is in level constantly: because the loss when branch that abrading block below the mill 8 or abrasive disc have the high end and mill ground.

When rocking arm 27 clockwise rotated, back screw mandrel 21 also clockwise rotated, and moved on the silk braid 22 that then slides, and move in the mobile swing arm 23 and then, thereby the machine rear end raise; Otherwise operating then, the machine rear end reduces.

Because the number of times that hand-rail type machine level(l)ing device uses in one day stone material renovation work is 4-5 time, adopt mutual vertical one little one 45 big degree bevel type gear interlock power transmissions, increased the arm of force of rocking arm simultaneously, more laborsaving, timesaving advantage, and more meet the habitual application of force behavior of Human Physiology mechanics.
