Abstract
The utility model relates to a material promotes the field, specifically is a bucket elevator head pulley, including the head pulley body, the head pulley body is split type structure, including sprocket ring gear and wheel hub, sprocket ring gear and wheel hub are as an organic whole through high strength bolt connection respectively. The utility model discloses a head pulley is become through high strength bolt group link together by the sprocket ring gear and the wheel hub that separately set up to after the head pulley wearing and tearing, only need change the sprocket ring gear can, reduced maintenance duration and equipment cost of maintenance.
Description
Technical Field
The utility model relates to a material promotes the field, specifically is a bucket elevator head pulley.
Background
The bucket elevator is suitable for vertically lifting materials from a low position to a high position, has the advantages of large conveying capacity, high lifting height, stable and reliable operation and the like, and is widely applied to the field of material lifting; along with the development productivity of society constantly improves, the bucket elevator promotes highly more and more high, and the volume of promoting is bigger and bigger, when the head pulley breaks down, needs whole change, has prolonged the activity duration, has reduced the operating efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem and providing a modified bucket elevator head pulley of being convenient for maintenance.
The utility model provides a problem, the technical scheme who adopts is:
the utility model provides a bucket elevator head pulley, includes the head pulley body, and the head pulley body is split type structure, including sprocket ring gear and wheel hub, sprocket ring gear and wheel hub are as an organic whole through high strength bolt connection respectively.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
the head pulley is formed by connecting a chain wheel gear ring and a hub which are separately arranged together through a high-strength bolt group, so that only the chain wheel gear ring needs to be replaced after the head pulley is worn, and the maintenance time and the equipment maintenance cost are reduced.
Preferably, the present invention further provides:
the chain wheel gear ring is of a split structure and comprises at least two chain wheel gear ring split bodies, the chain wheel gear ring split bodies are fixed on the hub through high-strength bolts, the chain wheel gear ring is not required to be integrally removed during replacement, and replacement efficiency is improved.
The sprocket gear ring and the hub are respectively provided with mutually matched step structures, and the step structures are connected together through high-strength bolts.
The number of teeth of the chain wheel gear ring is odd, the pitch of the chain wheel gear ring is half of the pitch of the chain meshed with the chain wheel gear ring, and when a head wheel with the odd number of teeth operates, the odd number of teeth and the even number of teeth are alternately meshed with the chain, so that the service life of the head wheel is prolonged.
Drawings
Figure 1 is a cross-sectional view of an embodiment of the invention;
fig. 2 is a top view of an embodiment of the invention;
in the figure: a sprocket ring gear 1; a hub 2; a high-strength bolt 3.
The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1 and 2, a bucket elevator head wheel, a head wheel body is composed of a chain wheel gear ring 1 and a hub 2, the chain wheel gear ring is provided with 23 teeth, a 42CrMo material forging process is adopted, and the surface hardness of the gear ring reaches more than 60 degrees after heat treatment; sprocket ring gear 1 and wheel hub 2 are equipped with the stair structure of mutually supporting respectively, link together through high strength bolt 3 between the stair structure and constitute complete head pulley, when the head pulley wearing and tearing back, only need change sprocket ring gear can, reduced maintenance time and equipment cost of maintenance.
The chain wheel gear ring 1 is of a split structure and is composed of two semicircular chain wheel gear ring split bodies, the chain wheel gear ring split bodies are fixed on the hub 2 through the high-strength bolts 3, the chain wheel gear ring 1 does not need to be integrally removed during replacement, and replacement efficiency is improved.
The pitch of the chain wheel gear ring 1 is 125mm, the pitch of the chain meshed with the teeth on the chain wheel gear ring 1 is 250mm, so that each chain is meshed with two teeth, when the chain wheel type automatic material lifting device is used, the head wheel is installed on the main shaft, the main shaft is connected with the driving device, the driving device drives the main shaft and the head wheel to rotate, the head wheel pulls the chain and the hopper to lift materials, the chain and the chain wheel gear ring 1 are repeatedly meshed to carry out transmission in the process, and if the chain is in transmission, the first circle is meshed with 2, 4, 6 and 8 … … even-numbered teeth, the second circle is meshed with 1, 3, 5 and 7 … … odd-numbered teeth, the third circle is meshed with 2, 4, 6 and 8 … … teeth, and so on, the service life of the head wheel with the odd-numbered teeth is twice that of the service life of the original head wheel.
The utility model discloses a head pulley is become through high strength bolt group link together by the sprocket ring gear and the wheel hub that separately set up to after the head pulley wearing and tearing, only need change the sprocket ring gear can, reduced maintenance duration and equipment cost of maintenance.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
