Abstract

The utility model relates to a mechanical hammering device, solving the problems of difficult operation and low automation degree for lifting type heavy hammers. The mechanical hammering device comprises a winding engine and a heavy hammer (8) hoisted at the front end of the wire rope for the winding engine; the reducer (5) of the winding engine is internally provided with a plurality of pairs of meshed transmission gears, wherein the driving gears (1) of one pair of the meshed gears are provided with gear gaps (9) so that the driven gears (2) are out of control when the gear gaps (9) are meshed with the driven gears (2); the heavy hammer (9) falls freely to smash the materials to be smashed under the effect of gravity. The utility model realizes automatic smashing and the lifting of the heavy hammer can be controlled without manual work by controlling an electric switch, thereby having fast smashing speed and good effect, saving great labor, improving production efficiency and saving production cost.

Description

A kind of mechanical type hammering device

Technical field

The utility model relates to a kind of hammering device, especially a kind of mechanical type hammering device.

Background technology

In foundry production, often need add some waste and old pig iron to smelting furnace, these pig iron majorities belong to the parts of scrapping machinery, because the size of a lot of parts is all bigger, be difficult to the waste and old parts of bulk to be pounded into fritter, make it to enter smoothly melting in the stove directly into the stove fusing.Break-iron needs weight, and by manually beaing with hand hammer one hammer,, not only labour intensity was big, and efficient is low, can not adapt to the big production of scale with hammering into shape in the past, and the mechanicalness weight becomes inevitable choice.Yet, the mechanical type weight almost is a blank at present, common a kind of hoisting type weight, be weight to be risen to certain altitude by the hoist engine wirerope, decontrol brake valve, allow its free-falling impacted object, this mechanical type weight complicated operation, difficulty is big, automaticity is low, is unfavorable for promoting the use of.

The utility model content

The problem that the purpose of this utility model is exactly the existing hoisting type weight complicated operation of solution, difficulty is big, automaticity is low provides a kind of mechanical type hammering device.

The technical solution adopted in the utility model is: a kind of mechanical type hammering device, it comprises hoist engine and is the weight that hangs over hoist engine steel cable front end, be connected with driving wheel and driven pulley respectively in hoist engine reducer output shaft and the reel rotating shaft, two meshed transmission gear, driving wheel is provided with tooth and lacks, tooth lacks when meshing with driven pulley, make driven pulley be in runaway condition, under the gravity effect, the weight free-falling, pound to quilt and pound object, make it broken.

Adopt technique scheme, tooth is scarce to make driven pulley out of control because driving wheel is provided with, and the weight free-falling is pounded into fritter with the waste and old parts of bulk; Owing to follow driven pulley around the cable cylinder and rotate together, last weight is followed around the cable cylinder and is done periodic rising and free-falling, has realized the purpose that the automation hammer is pounded.

In sum, the beneficial effects of the utility model are: pound owing to realized the automation hammer, do not need manually to control with the control power switch lifting of weight, therefore break-iron speed is fast, effective, has saved great amount of manpower, improve production efficiency, saved production cost.

Among the figure, 1, driving wheel, 2, driven pulley, 3, motor, 4, shaft coupling, 5 decelerators, 6, reel, 7, steel cable, 8, weight, 9, tooth lacks.

The specific embodiment

A kind of mechanical type hammering device of the utility model, as shown in Figure 1, it comprises hoist engine and is to hang weight 8 that hoist engine comprises motor 3, decelerator 5 and reel 6, motor 3 connects by shaft coupling 4 with decelerator 5.Be wound with steel cable 7 on the reel 6, weight 8 is hung by the front end system of steel cable 7.Be connected with driving wheel 1 and driven pulley 2, two meshed transmission gear in hoist engine decelerator 5 output shafts and reel 6 rotating shafts respectively.The driving wheel 1 of meshing gear is provided with tooth and lacks 9, and it is not have tooth in excircle the preceding paragraph of gear that tooth lacks 9, is the vacancy that inwardly concaves.Tooth lacks 9 with driven pulley 2 engagements the time, makes driven pulley 2 be in runaway condition, and under the gravity effect, weight 9 free-fallings are pounded to quilt and pounded object, make it broken.

Claims

1, a kind of mechanical type hammering device, it is characterized in that it comprises hoist engine and be the weight [8] that hangs over hoist engine steel cable front end, be connected with driving wheel [1] and driven pulley [2] respectively in hoist engine decelerator [5] output shaft and reel [6] rotating shaft, two meshed transmission gear, driving wheel [1] is provided with tooth and lacks [9], tooth lacks [9] when meshing with driven pulley [2], make driven pulley [2] be in runaway condition, under the gravity effect, weight [9] free-falling, pound to quilt and pound object, make it broken.
