Abstract

The utility model discloses a hammer shaft of a clinker crusher, which comprises a shaft pin, wherein two ends of the shaft pin are respectively provided with a limiting plate; one limiting plate is fixedly connected with the shaft pin, and the other limiting plate is detachably connected with the shaft pin through a bolt with a spring pad; and a location hole is arranged in the middle of the limiting plate fixedly connected with the shaft pin. In the utility model, a middle positioning mode is changed into a two-end limiting fixation mode, one end is welded with the limiting plate for location by the location hole, and the other end is connected with limiting plate through the bolt for limitation, so that the shaft pin can be prevented from moving axially so as to prevent the hammer shaft from withdrawing. The hammer shaft of the clinker crusher has a simple structure, is easy to manufacture, is fixed firmly, and ensures that the crusher can operate safely and reliably.

Description

Grog grinder hammerhead axle

Technical field

The utility model relates to a kind of grog crusher, particularly a kind of grog grinder hammerhead axle.

Background technology

In the manufacture of cement industry, the grog crusher is used for the grog piece that broken rotary kiln burns till, and the grog after the fragmentation is transported to clinker warehouse through the grog transfer roller.As shown in Figure 1, the fixing spacing employing of the hammer shaft of existing grog crusher drills through hole 9 in the intermediate radial of bearing pin 1, in through hole 9, wear the mode of steady brace, because tup centrifugal force in operation process is very big, often occur in through hole 9 place's off-axises in every month, fall the phenomenon of tup, cause the crusher vibration big, the electric current height causes the equipment jumping to stop, and whole production line stops production.Sometimes in addition occur tup drop enter clinker warehouse with the grog transfer roller after, to roll squeezer, cause fatal destruction with grog to roll squeezer.

The utility model content

The utility model provides a kind of fixed, safe and reliable grog grinder hammerhead axle in order to solve weak point of the prior art.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: grog grinder hammerhead axle, comprise bearing pin, described bearing pin two ends are respectively equipped with a limiting plate, wherein a limiting plate is fixedlyed connected with bearing pin, and another piece limiting plate removably connects by the bolt and the bearing pin of band spring pad.

Described limiting plate middle part of fixedlying connected with bearing pin is provided with pilot hole.

Adopt technique scheme, it is spacing fixing that the utility model makes two ends into by interfix, and an end welded limiting plate positions by pilot hole, and the other end connects limiting plate with bolt and carries out spacingly, prevents the bearing pin axial motion, in case hammer shaft withdraws from.The utility model is simple in structure, be easy to make, fixed, guarantee crusher operation safely and reliably.

Embodiment

As Fig. 2, shown in Figure 3, grog grinder hammerhead axle of the present utility model, comprise bearing pin 1, bearing pin 1 two ends are respectively equipped with limiting plate 2 and limiting plate 3, wherein limiting plate 2 is fixedlyed connected with bearing pin 1, limiting plate 2 middle parts are provided with and bearing pin 1 co-axial pilot hole 6, and another piece limiting plate 3 removably connects with bearing pin 1 by the bolt 5 of band spring pad 4.Bearing pin 1 need carry out modifier treatment HB=229-286, hard surfacing HRC=45-50.

The utility model adopts the spacing fixed mode in two ends, and an end welded limiting plate 2 positions by pilot hole 6, and the other end carries out spacing with bolt 5 connection limiting plates 3, prevent bearing pin 1 axial motion, in case hammer shaft withdraws from.

Claims
