Description

Shaking promotes strand grinding machine

Technical field

The utility model relates to mechanical lifting device technique field.

Background technology

In power construction technical field, a lot of operations are all to complete on the shaft tower of transmission line of electricity, a lot of heavy instrument or equipment all needs to be delivered on shaft tower, operator is the less portative instrument of portability in climbing tower bar, but can not directly bring tower bar by workman for many heavy instruments, artificial strength is difficult to carry, because transmission line of electricity is in farmland, construction machinery and equipment is inconvenient to enter, if made a forcible entry into, can cause large-area destruction to farmland, best bet is exactly to use the less manual machine of build to promote instrument or equipment, but manual machine is sometimes because the equipment that needs promote is heavier, can not meet lifting requirement, the elevating gear equipment being raised on the contrary that often can't bear the heavy load pulls displacement, have no idea to finish the work at all.

So for above problem, need a kind of build less, handled easily, and the men hoisting device that can not be shifted due to heavy burden in lifting process.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of shaking and promotes strand grinding machine, this strand grinding machine build is less, easy to operate, only need the one man operation crank just can be by instrument or equipment lifting to tower bar, and in unserviced situation, do not worry causing device displacement under the drive that promotes thing.

For addressing the above problem the technical scheme that the utility model takes be: a kind of shaking promotes strand grinding machine, it is characterized in that comprising support, on support, be provided with roll, one end of described roll is coaxially connected with the first gear, described the first gear also with support on the mutual interlock of the second gear, the circle centre position of described the second gear is connected with crank, on support, be also provided with gear screens bar, described gear screens bar one end is the dentalation suitable with the gear teeth shape of the first gear, the screens that cooperatively interacts of the dentalation of described gear screens bar and the gear teeth of the first gear, the rack leg bottom of described support is also provided with earth anchor.

Preferably, described earth anchor comprises the earth anchor point of ground anchor pole and the taper bottom it and is arranged on the spiral earth anchor sheet of ground anchor trend, be provided with the jack that penetrates ground anchor rod body at the top of ground anchor pole, on the ground anchor rod body between jack and earth anchor sheet, be provided with horizontally disposed reinforcing cover plate.

Preferably, the rack leg bottom of described support is connected with base plate, and described floor level setting is provided with through hole on base plate, and described ground anchor pole wears on through hole, and described base plate is being reinforced between cover plate and earth anchor sheet.

The beneficial effect that adopts technique scheme to produce is: the lifting strand grinding machine build of this shaking is less, can in the time promoting the instrument needing on tower bar, can not damage the farmland under tower bar, and the bottom of this strand grinding machine is provided with earth anchor, before promoting, first earth anchor and ground are fixed, fixation becomes as a whole with the earth to make device, in promoting, do not worry being like this subjected to displacement owing to promoting the overweight device that makes of thing, and can use for a long time, on the support of strand grinding machine, be also provided with gear screens bar, in the time that the lifting of lifting thing puts in place, gear can be blocked motionless, prevent gear revolution and cause lifting thing to fall.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

Fig. 1 structural representation of the present utility model.

Wherein, 1, support, 2, roll, 3, the first gear, 4, the second gear, 5, crank, 6, gear screens bar, 7, rack leg, 8, anchor pole, 9, earth anchor point, 10, earth anchor sheet, 11, jack, 12, reinforce cover plate, 13, base plate.

The specific embodiment

As shown in Figure 1: a kind of shaking promotes strand grinding machine, it is characterized in that comprising support 1, on support 1, be provided with roll 2, one end of described roll 2 is coaxially connected with the first gear 3, described the first gear 3 also with support 1 on the mutual interlock of the second gear 4, the circle centre position of described the second gear 4 is connected with crank 5, on support 1, be also provided with gear screens bar 6, described gear screens bar 6 one end are the dentalation suitable with the gear teeth shape of the first gear 3, the screens that cooperatively interacts of the dentalation of described gear screens bar 6 and the gear teeth of the first gear 3, rack leg 7 bottoms of described support 1 are also provided with earth anchor.

Earth anchor comprises the earth anchor point 9 of ground anchor pole 8 and the taper bottom it and is arranged on the spiral earth anchor sheet 10 of anchor pole 8 bottoms, ground, be provided with the jack 11 that penetrates ground anchor pole 8 bodies of rod at the top of ground anchor pole 8, on ground anchor pole 8 bodies of rod between jack 11 and earth anchor sheet 10, be provided with horizontally disposed reinforcing cover plate 12.Rack leg 7 bottoms of support 1 are connected with base plate 13, and described base plate 13 is horizontally disposed with, and on base plate 13, is provided with through hole, and anchor pole 8 covers in described ground are through on through hole, and described base plate 13 is being reinforced between cover plate 12 and earth anchor sheet 10.
