Abstract
The utility model relates to a transmission device and an overload protection device for solid combustion spiral transportation, which comprises a driving system for a coal feeder worm, wherein the system has a large transmission ratio and minimum power loss; the spring is used for adjusting the maximum load and is used as an overload protection device for the worm of the coal charger. The system has simple structure and no wearing parts.
Description
The utility model relates to a kind of driving mechanism and overload maintenance system that is used for the solid fuel helical feed.
The utility model needing to be particularly useful for the stoker stove of big speed ratio and rapid conversion velocity ratio.Also can be used for the not situation of co-content/weight ratio.
Existing various stoker mostly uses 600: 1 velocity ratio.Being that the employing velocity ratio is 100: 1 a worm couple in the first step of speed change, is that speed ratio is 6: 1 a sprocket wheel then.The kinetic equation loss of this mode is big and torque is big.
If worm screw is blocked by external object, motor must stop, maybe safety pin may be cut off, if or the worst situation be chain experience wear, then can chain rupture.
A kind of transmission device that is used for the stoker worm screw of stoker is disclosed among the Denmark DKA48762.This stoker worm screw drives by the driving arm that is connected of a ratchet mechanism by a door assembly with hinge and glass in right hand and left and joint pin, and this joint pin inserts in the groove of a variable-pitch, and the variation of this gradient will cause the variation of velocity ratio.In addition, in driving mechanism, also be provided with a friction clutch.This known drive mechanisms complex structure, so manufacture cost height.In addition, it comprises many wear-out parts, and velocity ratio and obtainable velocity ratio change also little.Thereby the friction clutch heating makes the lost of life when overload.
Disclose a kind of stoker transport system among the Norway NO A58078, wherein adopted a kind of safety pin.
Disclose a kind of stoker transport system among the Switzerland SE A117967, wherein adopted another kind of safety pin.
The shortcoming of prior art is chain rupture or stuck motor under the situation about worm screw may be blocked occurring.
The purpose of this utility model provides a kind of improved stoker system.A kind of system simple in structure just is provided, and this system has big speed ratio and has a spring that is used to adjust maximum load under the condition of kinetic equation loss minimum, and this spring is used as the overload holding device of helical conveyor simultaneously.
The purpose of this utility model is realized by following technical proposals; promptly provide a kind of stoker transport system that is used for heating plant according to the utility model; comprise a stoker worm screw; this worm screw is driven by a driving arm by the ratchet mechanism that is contained on it; ratchet mechanism is a running down transmission device; driving arm is that transmission changes arm; this arm moves radially to extend on the device from running down and also constitutes one with it; and which is provided with an elongated slot or a round; one end of driving arm penetrates among any; change arm in distance running down transmission device one segment distance place and transmission thus and form a kind of one way engagement-or push away or draw; described distance can change and change therefrom velocity ratio; its the other end then is articulated on the eccentric disc and by its driving, and driving arm comprises an overload protection arrangement.
Comprise an overload protection spring (7) according to the overload protection arrangement that is used for the stoker system of the present utility model; be arranged to push away or to draw the end of driving arm (1) to enter a selected hole (2 ') on this spring (7) facing to transmission variation arm (2); and can utilize tension device (8) to change the initial tensile force of spring (7), described tension device (8) penetrates in the hole (2 ') in the hole (2 ') that the end near driving arm (1) is engaged with.
Adopt crank-motion to pull running down transmission device (idlingbearing) according to the utility model, this running down transmission device draws a segment distance forward with worm screw, and makes worm screw static in backhaul.Be by push away or drawing rise screw rod rotate all push-jump moving in the safeguard construction of a kind of compressed spring type of employing.Drawing under the situation of rotation, driving arm elongation, thus spring is installed to the opposite side of gear arm, this just makes spring play the effect of stage clip.In addition, can perhaps will push away by changing the length of driving arm/pull bar move in the hole or in a seam stepless variation realize quick variation in the transmission device.
In principle, under the situation of critical component not being had harm overload protection arrangement can have no limits the running go down.
Utilize above-mentioned technology can obtain a kind of useful heating equipment, this apparatus structure is simple and have a transport system that is made up of part seldom.
Below with reference to accompanying drawings the utility model and other embodiment are described.
Fig. 1 represents a stoker transport system that is installed on the fuel storage hopper.
Fig. 1 has represented that is installed in the stoker transport system on the fuel storage hopper, and it comprises a running down transmission device, and this device is provided with the driving arm of a gear arm and a band overload protection arrangement.
As can be seen, the driving arm (1) of band overload protection arrangement is contained on the transmission variation arm (2) loosely.So just can change transmission device, thereby cause stoker worm screw (4) change in rotational speed.Transmission changes arm (2) and makes one with running down transmission device (3), and running down transmission device (3) is contained on the stoker worm screw (4).Whole stoker transport system is driven by a motor (5).Motor (5) passes to driving arm (1) by an eccentric disc (6) with actuation movement.
Driving arm (1) has the cylindrical structural of a band overload spring (7), and can be changed the maximum load of overload protection arrangement by tension device (8).
Claims (2)
1. the stoker transport system that is used for heating plant; comprise a stoker worm screw (4); this worm screw is driven by a driving arm by the ratchet mechanism that is contained on it; it is characterized in that; ratchet mechanism is a running down transmission device (3); driving arm is that transmission changes arm (2); this arm radially extends from the running down transmission device (3) and constitutes one with it; and which is provided with an elongated slot or a round (2 '); one end of driving arm (1) penetrate any several in; change arm (2) in distance running down transmission device (3) one segment distance places and transmission thus and form a kind of one way engagement-or push away or draw; described distance can change and change therefrom velocity ratio; its the other end then is articulated on the eccentric disc (6) and by its driving, and driving arm (1) comprises an overload protection arrangement.
2. the system as claimed in claim 1; it is characterized in that; overload protection arrangement comprises an overload protection spring (7); be arranged to push away or to draw the end of driving arm (1) to enter a selected hole (2 ') on this spring (7) facing to transmission variation arm (2); and can utilize tension device (8) change spring (7) initial tensile force, described tension device (8) penetrates in the hole (2 ') in the hole (2 ') that the end near driving arm (1) is engaged with.
