Grinding machine holder watt replacing lifting cart

Technical field

The utility model relates to a kind of lifting cart that grinding machine holder watt and related components thereof are changed usefulness that is applied to, and belongs to the B62B3/00 class.

Background technology

The report that before the utility model, does not also have similar go-cart, changed a heavily about grinding machine holder of about 100 kilograms watt or relevant parts all come handling by means of the overhead traveling crane about 30t in the past, this is not only the waste of resource, moreover come the handling small articles neither easy to operate with big overhead traveling crane, also dangerous; The holder that changes in addition watt must be placed on the place of appointment or overhead traveling crane hang less than the place, also need manpower to remove and change, labour intensity is big, work efficiency is low again.

Summary of the invention

Task to be solved in the utility model provides a kind of being exclusively used in and changes grinding machine holder watt and collection carrying and laborsaving, the simple in structure workable grinding machine holder watt replacing of people from province that is lifted on one with lifting cart or be referred to as Trolley.

For solving above-mentioned task, the technical solution adopted in the utility model is: the chassis that makes a rectangular body or square body of metallic material (as shaped steel), on this chassis, can push away and put all kinds of holders watt and related components thereof, play counterweight to lifting cart simultaneously.Be fixed in the column of chassis one end and be set with tooth bar, the upper end of tooth bar is equipped with can 360 ° of rotating crossbeams, and the roller that chain and suspension hook are housed is assemblied in the crossbeam, and it can move around in crossbeam.Gear is installed in the casing near tooth bar, and tooth on the gear and the tooth on the tooth bar mesh each other, and an end that is arranged in the casing screw mandrel is positioned at the hole of column, is processed with driving cog on the screw mandrel, driving cog again with gear on tooth mesh each other.The other end of screw mandrel stretches out casing, and the end of external part is square toes, with a packing ring and screw rocking handle is sleeved on the square toes of screw mandrel.Two bearings (as antifriction-bearing box) are equipped with in the upper end of tooth bar, and a headgear of crossbeam is in the outer rim of this two bearings.Screw passes platen crossbeam is fixed on the tooth bar.The front end on chassis (promptly by stud end) is equipped with two tight pulleys, and two cardan wheels are equipped with in the rear end on chassis, protection railing are housed all around on the chassis, and the rear end railing is higher than the front end railing, the use of double as push rod.

Adopt grinding machine holder watt replacing that as above technical scheme provides with lifting cart compared with prior art, its beneficial effect is:

1. carry laborsavingly, lifting is convenient;

2. workable, save manpower 50～70%;

3. rational in infrastructure, practicality is wide, uses than reducing more than 60%;

4. safe and reliable, be convenient to safeguard.

Description of drawings

Accompanying drawing 1 is the integral structure scheme drawing of grinding machine holder described in the utility model watt replacing with lifting cart, also is specification digest accompanying drawing of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Grinding machine holder described in the utility model watt replacing with lifting cart by tight pulley 1, cardan wheel 2, chassis 3, column 4, tooth bar 5, gear 6, screw mandrel 7, casing 8, rocking handle 9, packing ring 10, screw 11 or 11 ' or 11 " or 14, bearing 12, platen 13, sheath 13 ', crossbeam 15, roller 16, chain 17, suspension hook 18, protection railing 19 form.Cardan wheel 2 is equipped with in the rear end that the front end on the rectangular body of making of metallic material or the chassis 3 of square body is equipped with tight pulley 1, chassis 3, protection railing 19 is arranged around the chassis 3, column 4 is fixed on the place ahead on chassis 3, and the position is in the end middle part of two tight pulleys 1, column 4 can be the hollow pillar type column, tooth bar 5 is sleeved in the column 4, and tooth bar 5 can freely move up and down in column 4.Gear 6 is installed in the casing 8 near tooth bar 5.Tooth on tooth on the gear 6 and the tooth bar 5 meshes each other.An end that is arranged in the screw mandrel 7 of casing 8 is positioned at the hole (as semicircle orifice) of column 4, is processed with tooth on the screw mandrel 7, and the tooth on tooth on the screw mandrel 7 and the gear 6 meshes each other.The other end of screw mandrel 7 stretches out casing 8, and rocking handle 9 is sleeved on the square toes of screw mandrel 7, and packing ring 10, screw 11 are housed on square toes ", rocking handle 9 is fastened on the square toes of screw mandrel 7.Casing 8 usefulness screws 11 or 11 ' a be fixed on side of column 4.Bearing 12 is equipped with in the upper end of tooth bar 5, and a headgear of crossbeam 15 is contained in the outside of bearing 12, and crossbeam 15 can be neatly rotated around tooth bar 5, have in the outer of bearing 12 sheath 13 ', screw 14 passes platen 13 crossbeam 15 is fixed on the tooth bar 5.Crossbeam 15 is semi-enclosed square frame shape, and there is guide rail both sides in the transversal surface of crossbeam 15, and roller 16 is assemblied in the crossbeam 15, and there is chain 17 lower end of roller 16, and there is suspension hook 18 termination of chain 17.

During enforcement, swing protection railing (being push rod) 19, centering is advanced and is trampled line, and tight pulley 1, cardan wheel 2 rotation drive go-carts are advanced or are retreated.Shift lifting cart the proximal most position of grinding machine onto, rotating beam 15, shifting roller 16, suspension hook 18 hook the rope that is about to the holder changed watts 20.Shaking rocking handle 9 " just " changes, gear 6 is rotated, the rotation of gear 6 makes tooth bar 5 upwards motion in column 4, and the upward movement of tooth bar 5 makes crossbeam 15 synchronous upward movements drive suspension hooks 18 actions will ask watts 20 to sling, at this moment operating personal drag chain 17 also rotating beam 15 to 3 tops, go-cart chassis; Shaking rocking handle 9 negations changes, and tooth bar 5 moves downward, and will ask watts 20 to be lowered on the chassis 3; Repeat as above to move, new (or appointment) holder watts 20 sling move to the grinding machine limit and put down and assemble, after crossbeam 15 being gone back to the top on chassis 3 lifting cart is pushed back appointment (or original) place, finish holder watt replacing program, reach purpose described in the utility model.
