Abstract

The utility model relates to a driving mechanism for a rolling grate, which solves the problem that the existing rolling grate adopts a driving mechanism with a chain; the tensile strength of the chain is not enough under the condition of heating, and thus the chain is frequently easy to break to cause unable normal use and large quantity of maintenance. On the basis of an original rolling grate, the utility model cancels the driving mechanism with the chain; a rolling shaft of a grate is driven by that a ratchet, an oscillating rod and a ratchet pawl are connected and matched. The utility model has the advantages of high strength, stable running and long service life.

Description

The transmission mechanism of rolling fire grate

The utility model belongs to a kind of mechanism of combustion apparatus; Be particularly related to a kind of transmission mechanism of rolling fire grate.

Fire grate is that the important master of boiler becomes part, and the quality of its runnability directly has influence on the thermal efficiency of boiler.Existing fire grate is many based on traveling-grate stoker, and this fire grate is in operation and can not becomes flexible coal, easily coking, thereby coal can not all burn, and is in operation and also leaks coal easily, wastes energy, and air quantity is inhomogeneous, and it is insufficient to burn, and also can produce a large amount of SO in combustion process ₂With NO gas, contaminated air, destroy ecological environment.Be head it off, designed the energy-efficient carrier bar rolling fire grate of ZL9422486.0.But owing to adopt chain drive, and not enough in the situation lower chain tension intensity of heating, usually easily disconnect, cause and can not normally use, maintenance capacity is big; Thereby bring difficulty to heating.

The purpose of this utility model is, solves existing existing problem, provides a kind of transmission stable, intensity height, the transmission mechanism of the rolling fire grate of long service life.

The utility model is achieved in that on the basis of original rolling fire grate, the cancellation chain drive, cooperate with the interior hexagon installation of ratchet at the two ends of every axis of rolling hexagon, the ring-type position of ratchet is sleeved in the swing set ring of swing arm, and fixes by end cap and screw.The other end of swing arm is provided with connecting hole, is used for being connected with the bent axle of boiler decelerator.Middle part at swing arm connects ratchet pawl by bearing pin, and the claw of ratchet pawl cooperates transmission with the ratchet of swing arm, the other end of ratchet pawl and be located between the locator card on the swing arm extension spring is installed.

Advantage of the present utility model is, has adopted ratchet mechanism, the intensity height, and equipment operation is stable, long service life.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is that the B of Fig. 2 is to view;

Fig. 4 is the structural representation of fire grate;

Describe in detail below in conjunction with accompanying drawing:

As shown in the figure, on the basis of original rolling fire grate, the cancellation chain drive cooperates with the interior hexagon installation of ratchet 1 at the two ends of the every axis of rolling 11 hexagon 12, the ring-type position of ratchet 1 is sleeved in the swing set ring 9 of swing arm 2, and fixing by end cap 8 and screw 10.The other end of swing arm 2 is provided with connecting hole 6, is used for being connected with the bent axle of boiler decelerator.Connect the middle part of ratchet pawls 3 by bearing pin 7 at the middle part of swing arm 2, the claw of ratchet pawl 3 cooperates transmission with ratchet 1, the other end of ratchet pawl 3 and be located at installation extension spring 4 between the locator card 5 on the swing arm 2.During use, fire grate is stable.

Claims

1, a kind of transmission mechanism of rolling fire grate, on the basis of original rolling fire grate, the cancellation chain drive, it is characterized in that, cooperate with the interior hexagon installation of ratchet at the two ends of every axis of rolling hexagon, the ring-type position of ratchet is sleeved in the swing set ring of swing arm, and fixes by end cap and screw; The other end of swing arm is provided with connecting hole; Middle part at swing arm connects ratchet pawl by bearing pin, and the claw of ratchet pawl cooperates transmission with the ratchet of swing arm, the other end of ratchet pawl and be located between the locator card on the swing arm extension spring is installed.
