Description
Technical field
The utility model relates to a kind of extracting tool of belt roller, particularly a kind of device of changing carrying roller.
Background technology
Belt feeder is the abbreviation of belt conveyor, and belt feeder uses the continuous or intermittent movement of conveyer belt to carry the different article of various weights, both can carry various bulk cargos, also can carry the little part goods of single-piece weight such as various cartons, packaging bag, and is of many uses.Belt feeder is carried steadily, and material and conveyer belt do not have relative motion, can avoid the damage to transported substance.Noise is less, is suitable for the more quiet occasion of working environment requirement.Simple in structure, to be convenient to safeguard, energy consumption is less, and use cost is low.
In the actual job, owing to safeguarding cleaning, damaging and change or according to reasons such as need of productions, often will change carrying roller, in integrated mill, because the volume of belt roller is larger, the shelf of belt is shorter, when roll change, need the staff to creep into below the belt, the replacing time is long, and belt is heavy, and changes difficulty, personal injury accident easily occurs, and has caused certain potential safety hazard for on-the-spot staff.Such as when the replacing width is the above belt roller of 1000-1200 millimeter, needing 6 people to operate simultaneously, specifically by 4 human iron pipes belt is lifted, the support force of everyone weight of bearing, pulling force and boxhole breast board leather is 50kg approximately, strength is propped up the personnel that changing carrying roller is come to harm, and 2 people change carrying roller.Because light is dark, narrow space, discharging point carrying roller minimum spacing is 0.5m, the heavy 12.06kg of carrying roller, the people will change in the middle of dropping into belt above the waist, and 4 people lift motionless in replacing, have a rest, then belt is lifted again and change, so cause the replacing time long, have potential safety hazard.
In sum, need a kind of servicing unit for changing carrying roller of design, address the above problem.
The utility model content
The purpose of this utility model is to propose a kind of device of changing carrying roller, time-consuming when solving artificial replacing carrying roller, effort, and operate unsafe problem.
For reaching this purpose, the utility model by the following technical solutions:
A kind of device of changing carrying roller comprises footstock, lifter and base, and described lifter bottom is fixed on the base, and described lifter top is installed with footstock.
As a preferred version, described lifter adopts the feed screw nut lifting, comprise leading screw, rotating disc, feed screw nut, leading screw support, described leading screw top and footstock are fixed together, described leading screw passes feed screw nut, and described feed screw nut is welded on rotating disc central authorities, and described feed screw nut lower end is inserted in leading screw support central authorities, be rotationally connected with the leading screw support, described leading screw support bottom is fixed on the base.
As further preferred version, be bolted to connection between described leading screw support bottom and the base.
As preferred version further, described base is channel-section steel, and described footstock inboard has a concave groove, is used for holding up belt.
The utility model is simple in structure, and is with low cost, easy to operate, base adopts channel-section steel, be matrix, can be stuck on the belt holder, slide when avoiding changing carrying roller, leading screw support and base are fixed together, strengthened steadiness, lifter adopts the feed screw nut lifting, can realize the leading screw lifting by rotating circular disk, thereby belt can be held up, improve efficient and the security of changing carrying roller.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure:

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Fig. 1 is the utility model implementation structural representation.
Comprise among the figure: footstock 1, lifter and base 6, described footstock 1 is spill, described lifter adopts the feed screw nut lifting, comprise leading screw 2, rotating disc 3, feed screw nut 4, leading screw support 5, described leading screw 2 tops and footstock 1 are fixed together, described leading screw 2 passes feed screw nut 4, described feed screw nut 4 is welded on rotating disc 3 central authorities, described feed screw nut 4 lower ends are inserted in leading screw support 5 central authorities, be rotationally connected with leading screw support 5, described leading screw support 5 bottoms are bolted and are fixed on the base 6; Described footstock 1 is fixedly mounted on leading screw 2 tops; Described base 6 adopts channel-section steel, utilizes its concave structure, can be stuck on the belt holder, slides when preventing from changing carrying roller.
The utility model uses in pairs, during application, the groove of base 6 is stuck on the belt holder, and screens is the required replacing carrying roller 200mm of distance place, and two devices are alignd in belt both sides operating personnel range estimation;
Need two workmans, adopt an iron pipe for subsequent use, length than replacing carrying roller epithelium belt length 600mm about, iron pipe is placed on the footstock 1 of the present utility model passing below the belt;
The rotating disc 3 that turns clockwise makes the belt lifting height be advisable greater than about 1 times of replacing idler diameter;
With required replacing idler removal, lay new carrying roller;
Opposite spin rotating disc 3 drops to and can take off smoothly till the iron pipe;
Removal the utility model more changes jobs complete, and two people change discharging point place carrying roller on average about 12 minutes.
The utility model is simple in structure, and is with low cost, easy to operate, base 6 adopts channel-section steel, be matrix, can be stuck on the belt holder, slide when avoiding changing carrying roller, leading screw support 5 is fixed together with base 6, strengthened steadiness, lifter adopts the feed screw nut lifting, can realize the leading screw lifting by rotational circle 3 dishes, thereby belt can be held up, improve efficient and the security of changing carrying roller.
