Description

A kind of easy artificial tackle gear

Technical field

The present invention relates to a kind of easy artificial tackle gear.

Background technology

At present, when moving large and medium-sized weight, it may also be useful to driving, lifting machine are conventional modes, but for some small-sized weights, such as the object of mobile several hundred kilograms, workman lifts needs two to three people, it is necessary to more labor force, labour intensity greatly, and have potential safety hazard. Particularly needing the small-sized weight of frequent movement, enter just not saying can place reach liftmobile, whether liftmobile takies steric restriction workman is done things, and whether driving builds track to this place; Being exactly that liftmobile can be entered, driving can be arrived, stop always dynamic only mobile small-sized weight be also waste one's talent on a petty job, the wasting of resources, if then energy dissipation of frequently coming is more serious. In smelting industry, the refining furnace of refining silver, furnace bottom and bell are what to separate. Bell heavily reaches hundred kilograms, and furnace bottom of fining furnace is high about one meter, before refining furnace blow-on, after the preparation work of furnace bottom is carried out, it is necessary to bell is raised about 1 meter and is placed on furnace bottom of fining furnace; Refining to be removed bell after completing, and facilitates workman clear up smelting furnace and prepare work for blow-on next time; During work, refining furnace is in the condition of high temperature, and bell surface temperature is also high, sometimes because when various reason needs to adjust bell position, because bell temperature height is very heavy again, artificial adjustment difficulty is big and dangerous.

In smelting industry, refining furnace, in order to make full use of heat, saves the energy, it is all two public heating mouths of stove, as having a heating mouth in the middle of 1, No. 2 refining furnace, heat is by pipeline shunt to 1, No. 2 refining furnaces, and 3, No. 4 refining furnace heating mouths are between 3, No. 4. General in smelting enterprise, refining furnace builds side by side, a row ten, basic blow-on simultaneously during production.

Summary of the invention

Inconvenient problem is moved in order to overcome small-sized weight. The present invention provides one easy artificial tackle gear, it may also be useful to the easy artificial tackle gear of this one, workman's energy safe and convenient frequently completes the work of mobile small-sized weight.

In order to achieve the above object, the technical solution adopted for the present invention to solve the technical problems is following design:

Fixing pillar bottom is connected with base, base can be fixedly connected with ground and can also be fixedly connected with sidewall, fixing column upper section has shaft portion, coordinate with an axle sleeve, bearing is had between the shaft portion of fixing column upper section and an axle sleeve, axle sleeve can on fixing pillar 360 ° rotate freely, a described axle sleeve is inverted cup-shape, is conducive to preventing dust from entering in the bearing between the shaft portion of fixing column upper section and an axle sleeve.Fulcrum puts and is welded with cantilever, and the left part of cantilever is welded with front-end bearing pedestal and rear bearing block, and rocking bar is from front to back through front-end bearing pedestal, rear bearing block, and rocking bar rear end is fixed by rocking bar snap ring. Circle pipe front and back ends be welded on front-end bearing pedestal, rear bearing block respectively, active card bar from back to front from circle pipe through, described active card bar is " L " type. The right portion of cantilever is welded with suspended axle, and pulley sleeve is fixed on suspended axle, the pulley in steel wire penetrating pulley sleeve, and the two ends of wireline connect rocking bar, hook respectively.

The benefit of the present invention is: can save labor force, reduces labour intensity, eliminates safe hidden trouble, it is possible to allows safety of workers is convenient moves small-sized weight frequently. During refining furnace blow-on, a workman can complete the position adjustment of high temperature bell, simultaneously, it is possible to just can manage all refining furnaces with less workman.

Accompanying drawing explanation

Below in conjunction with drawings and embodiments, the present invention is further described.

Embodiment

Fixing pillar 1 bottom is connected with base, base can be fixedly connected with ground and can also be fixedly connected with sidewall, shaft portion is arranged at fixing pillar 1 top, coordinate with an axle sleeve 2, bearing is had between the shaft portion on fixing pillar 1 top and an axle sleeve 2, axle sleeve 2 can on fixing pillar 1 360 ° rotate freely, a described axle sleeve 2 is inverted cup-shape, is conducive to preventing dust from entering in the bearing between the shaft portion on fixing pillar 1 top and an axle sleeve 2. Propping up and be welded with cantilever 3 on axle sleeve 2, the left part of cantilever 3 is welded with front-end bearing pedestal 4 and rear bearing block 5, and rocking bar 6 is from front to back through front-end bearing pedestal 4, rear bearing block 5, and rocking bar 6 rear end is fixed by rocking bar snap ring 7. The front and back ends of circle pipe 8 is welded on front-end bearing pedestal 4, rear bearing block 5 respectively, and active card bar 9 passes from circle pipe 8 from back to front, and described active card bar 9 is " L " type. The right portion of cantilever 3 is welded with suspended axle 10, and pulley sleeve 11 is fixed on suspended axle 10, and the pulley of wireline 12 in pulley sleeve 11, the two ends of wireline 12 connect rocking bar 6, hook 13 respectively.

During work, active card bar 9 is extracted out one end distance backward, rocking bar 6 can be rotated freely, and small-sized weight is caught in hook 13, workman's rotating rocker 6, weight is raised, when arriving desired height, active card bar 9 is pushed ahead, makes active card bar 9 block rocking bar 6, promoting cantilever 3 again, cantilever 3 drives weight to rotate; When arriving the top being put place when weight, moving active card bar 9 backward, reverse rotation rocking bar 6, puts down weight.

In smelting industry, a kind of easy artificial tackle gear is generally arranged between two refining furnaces, and such as 2, No. 3, between 4, No. 5 refining furnaces, axle sleeve 2,360 ° of rotations can just look after two refining furnaces, makes maximum resource utilization. Because refining furnace furnace wall has more than one meter high, in order to save space, the base being connected with fixing pillar 1 is generally be fixed on refining furnace sidewall.

In material object of the present invention, cantilever 3, front-end bearing pedestal 4, rear bearing block 5, circle pipe 8 are all gather materials on the spot in factory, cantilever 3, front-end bearing pedestal 4, rear bearing block 5, material is discarded channel-section steel, front-end bearing pedestal 4, rear bearing block 5 are the channel-section steel cutting out a circular hole with flame cutting in centre, the diameter of circular hole is greater than the diameter of rocking bar 6, and circle pipe 8 is discarded water pipe.Use other better material, more the accessory of specification, as long as described function can be reached also belong to the scope of the invention.
