Description

A kind of coil of strip conveying track

Technical field

The utility model relates to the transportation technology field, particularly coil of strip conveyer chain track.

Background technology

The conveyer chain equipment of transportation coil of strip all will be used in the hot rolling unit of iron and steel enterprise when cold rolling unit feed both at home and abroad.Conveyer chain with hot rolling conveyer chain system is example, and the rail set that supports its sprocket wheel adopts the rolling section bar of monolateral two " L " types, adopts the welding of 100*100 spacing fixing with the lower tracks beam.Under high load capacity, high temperature, high successional operative condition, serious deterioration has taken place track the rail set of supporting wheel, mainly shows for a long time: track extrusion, wearing and tearing, solder joint come off, radius off-set joint etc.Especially in maintenance, because fixing rail damage and the wearing and tearing of welding cause the maintenance activity time long, equipment point-detecting and state recognizing can't normally be carried out, have a strong impact on the balance of normal operation and company's logistics of conveyer chain, track cost of maintenance also short, equipment in service life is high simultaneously.

Equipment is through year in year out running, though the problem that takes place is corresponding increasing inevitably, but the track of existing its sprocket wheel of supporting adopts monolateral two L type section bars, adopt the fixing structure design of welding with the lower tracks beam, aggravated the distortion that track causes because of welding stress concentration, under the reverse stress effect, cause the track sealing-off, can't guarantee that smooth running is in rectilinear direction, and corresponding distortion walking also can cause the track inordinate wear, these problems all can influence the load of chain in operational process and strengthen, and cause the overcurrent jumping; In addition, rail set adopts the fixing structure design of welding, and problem such as have track installation accuracy control difficulty, track is yielding when installing causes rail damage and the stuck fault of chain that causes.In addition, adopt the fixing track structure design of welding also to have following 2 deficiencies:

Setting accuracy is poor: its installation accuracy control difficulty of existing rail set, 680 meters long track welding can't be avoided the distortion of track, causes " snake " shape distortion of track.

Maintenance property is poor: existing welding fixed type track maintenance is installed loaded down with trivial details, and the maintenance load is big.And repair quality can't satisfy on-the-spot actual operating needs.

Therefore, must propose improvement project, improve the stability of coil of strip conveyer chain operation, guarantee the production logistics balance the track that supports its sprocket wheel.

Summary of the invention

The purpose of this utility model is to provide a kind of coil of strip conveying track, effectively eliminates conveyer chain track the be squeezed distortion that easily produces, the defective of flange, and avoids causing thus the overcurrent that chain is stuck, motor is frequent and jump faults such as electricity; Simultaneously, can also guarantee the spacing of two-orbit, effectively eliminating the conveyer chain track is squeezed yielding and defective flange, and stop to cause thus the overcurrent that chain is stuck, motor is frequent and jump faults such as electricity, improve the transport capacity of conveyer chain, guarantee to produce the normal supply of materials, further improve service life of equipment, thereby effectively reduce breakdown of equipment and maintenance load.

For achieving the above object, the technical solution of the utility model is,

A kind of coil of strip conveying track comprises, in pairs the track that is provided with and support beam; This track is the L type; L type step one side of the described track formation second step that also stretches out, and this second step upper surface is lower than L type step end face; Have knock hole on described L type step and the second step, by joint bolt track is connect mutually with support beam respectively.

Further, the contact surface of described track and support beam also has cooresponding keyway, and by positioning key track and support beam is clamped in positioning key in the mutual cooresponding keyway separately, avoids conveyer chain track sidesway, improves the intensity and the precision of track.

Again, described track keyway and positioning key distribute and are arranged at place, nearly two ends of track, and described keyway and positioning key two ends are the design of circular arc type mosaic texture, so that processing.

The keyway of described track and support beam and positioning key are continuous or uniform setting at interval.

Monolateral two " L " type tracks welding fixed sturcture when the utility model has been cancelled the conveyer chain original design.Design by the brand new track structure, and fixed form changes bolted connection into, makes incorporate track can avoid conveyer chain track sidesway effectively, improves the intensity and the precision of track, improve service life greatly, and the maintenance load reduces greatly and the maintenance installation becomes simple.

The beneficial effects of the utility model

1. stopped fault because of the stuck chain of rail damage;

2. avoid the frequent overcurrent of conveyer chain motor to jump electric fault;

3. improve the track setting accuracy and guarantee the chain traveling comfort;

4. in cost of maintenance that has reduced equipment and maintenance load, improve the transport capacity of cold-rolled steel coils, guaranteed the balance of logistics.
