Abstract
The utility model discloses a kind of dummy ingot dolly with weight-driven, belong to steelmaking equipment field, it is characterised in that：Including dolly, chain, drive sprocket, driven sprocket, weight-driven and reducing motor；Described drive sprocket is located at the end at the top end of track, and drive sprocket is driven by reducing motor, and described driven sprocket is located on the car body of dolly；Described chain one end is fixing end, and the other end is free end, and wherein fixing end is fixed on bypasses driven sprocket and drive sprocket respectively close to the position of drive sprocket, chain, and chain free end is hung down from drive sprocket, and chain free end is fixedly connected with weight-driven.There is the characteristics of extending service life compared with prior art.
Description
Technical field
It the utility model is related to a kind of steelmaking equipment, particularly a kind of dummy ingot dolly suitable on slab caster.
Background technology
No matter current slab caster takes online or offline deingot mode, to ensure high-efficiency and continuous production, dummy bar chain
It is intended to be deposited by casting stream using certain device.Dummy ingot storage trolley is typically taken to be connected by chain at present, such as Fig. 1 institutes
Show, dolly is respectively arranged in the front and the rear with a sprocket wheel, is connected between two sprocket wheels by chain, and the chain link of chain is fixed with dolly to be connected
Connect, by sprocket wheel, chain structure driving under, drive dolly run along before and after track.In this configuration, driven pulley is positioned at casting
Stream roller-way lower section is in runner, and repair and maintenance replacing is not easy after its bearing damage.Above-mentioned dummy ingot storing unit body passes through a set of
Regulating bolt adjusts chain elasticity, and chain is easily connected at bearing pin with trolley body from chain and wrecks, needed after wrecking by
Dynamic manpower of extracting out is attached recovery adjustment to scene, influences production event and happens occasionally, and personnel are related to work in handling failure
Industry safety.Two sprocket wheels are middle, below hot base because being fixed on for other chain, cause it because the base that is heated scorches the deformation that is distorted,
It certainly will influence normally to send after chain torsional deformation, receive dummy bar chain, need to periodically be changed.
Utility model content
Technical assignment of the present utility model is to be directed to above the deficiencies in the prior art, there is provided a kind of dummy ingot with weight-driven
Dolly.
The technical scheme in the invention for solving the technical problem is：A kind of dummy ingot dolly with weight-driven, its feature
It is：Including dolly, chain, drive sprocket, driven sprocket, weight-driven and reducing motor；Described drive sprocket is located at rail
The end at the top end in road, drive sprocket are driven by reducing motor, and described driven sprocket is located on the car body of dolly；Described chain
Bar one end is fixing end, and the other end is free end, and wherein fixing end is fixed on bypasses respectively close to the position of drive sprocket, chain
Driven sprocket and drive sprocket, chain free end are hung down from drive sprocket, and chain free end is fixedly connected with weight-driven.
Above-mentioned weight is hopper construction, and heavy hammer structure is collectively constituted in waste materials such as hopper addition steel scraps.
The weight of above-mentioned weight is G*sin α/2, and wherein G is equal to dolly and dummy ingot storage gross weight, α be trolley track with
Horizontal line angle.
Above-mentioned weight-driven is placed in the trench below casting stream roller-way by increasing the modes such as changed course sprocket wheel.
Above-mentioned dolly is provided with anti-tipping guide wheel.
Compared with prior art, the utility model has beneficial effect following prominent：
1st, increase the service life, reduce the probability that accident occurs；
2nd, structure is simplified, reduces cost；
3rd, convenient maintenance and replacement.
Brief description of the drawings
Fig. 1 is the structural representation of existing dummy ingot carriage device.
Fig. 2 is structural representation of the present utility model.
Embodiment
The utility model is further illustrated with reference to specification drawings and specific embodiments.
As shown in Fig. 2 the utility model includes dolly 2, chain 3, drive sprocket 4, driven sprocket 7, the device of weight 5 and subtracted
Speed motor.Described drive sprocket 4 is located at the end at 1 top end of track, and drive sprocket 4 is driven by reducing motor, it is described from
Movable sprocket 7 is located on the car body of dolly 2.Described one end of chain 3 is fixing end, and the other end is free end, and wherein fixing end is consolidated
It is scheduled on the position close to drive sprocket 4, chain 3 bypasses driven sprocket 7 and drive sprocket 4 respectively, and the free end of chain 3 is from drive chain
Hung down on wheel 4, the free end of chain 3 is fixedly connected with the device of weight 5.Described weight 5 can be a single part, can also
It is hopper construction, the structure of weight 5 is collectively constituted in waste materials such as hopper addition steel scraps.The preferred G*sin α of weight of described weight 5/
2, wherein G are equal to dolly 2 and dummy ingot storage gross weight, and α is the track 1 of dolly 2 and horizontal line angle, so as to make the weight of weight 5
Power is equal to the pulling force of chain 3 with dolly 2, makes the pulling force at the both ends of drive sprocket 4 equal.The device of weight 5 can be filled individually in driving
Lower section is put, can be also placed in by increasing the modes such as changed course sprocket wheel in the trench below casting stream roller-way.
To avoid dolly 2 from tumbling, dolly 2 is provided with anti-tipping guide wheel.
Beneficial effects of the present invention：This dummy ingot dolly 2 provided by the invention, using driven sprocket 7 and the body of dolly 2 into
One, chain 3 are arranged to open type, and rear portion carries out tensioner by the device of weight 5, and drive sprocket 4 is driven by reducing motor, so as to
Drive dolly 2 to carry out operation up and down, avoid the base that is heated of chain 3 from scorching the bending lost of life, the body of dolly 2 connects with chain 3
Pin axle wrecks, adjustment bolt releases, and is reached extension chain 3 by movable sprocket problem in passive processing runner 6 and used week
Phase, quick handling failure and the effect for ensureing processing procedure safety.
It should be noted that the utility model is described in detail for particular of the present utility model,
For those skilled in the art, it is carried out in the case of without departing substantially from spirit and scope of the present utility model various
Obviously change all within the scope of protection of the utility model.
