Description

Coil of strip promotes step rate

Technical field

The utility model relates to a kind of mechanical equipment of steel rolling, particularly reference and a kind of coil of strip promotes step rate.

Background technology

At the entrance and the outlet section of cold rolling continuous process for producing line, often use step rate to carry out the coil of strip transportation, it can once move certain distance towards a direction with a plurality of coil of strips simultaneously; Step rate at first promotes coil of strip, be higher than fixed saddle after, traversing cylinder pushes step rate moves; Treat coil of strip move to next fixed saddle directly over the time, step rate descends, coil of strip drops on the fixed saddle; Because step rate is provided with a plurality of saddles position, therefore can transport a plurality of coil of strips simultaneously, but in the design of step rate at present; The installation absolute altitude of fixed saddle is identical, can't in the transportation coil of strip, coil of strip be promoted to a high position by low level; Now if operation unit absolute altitude condition of different before and after existing, generally can only be that the mode through the crane transportation is promoted to a high position with coil of strip, and can only a coil of strip; The single-piece operation of a coil of strip, work efficiency is lower.

Summary of the invention

In view of this, the main purpose of the utility model is to provide a kind of coil of strip to promote step rate, through the present technique scheme; Can satisfy the requirement that coil of strip in enormous quantities promotes and descends; Simple to operate, degree of automation is high, thereby has remedied the deficiency that exists in the prior art.

In order to achieve the above object; The technical scheme of the utility model is achieved in that a kind of coil of strip promotes step rate, includes fixed saddle, track girder, track and mobile device, and said several fixed saddles are arranged on the near coal-mine both sides of ground; Two track girders that laterally arrange are arranged at the bottom of the foundation pit; Said mobile device is made up of wheel and vehicle frame, and wheel is installed on the vehicle frame, and two groups of wheels in two mobile devices are placed on respectively on two tracks on the track girder; Also include beam body, movable saddle, lifting hydraulic actuating cylinder, traversing hydraulic actuating cylinder; Said lifting hydraulic actuating cylinder is fixed on the vehicle frame, and the movable end that promotes hydraulic actuating cylinder is hinged on the bottom of beam body, and said traversing hydraulic actuating cylinder is arranged on track girder one side at the bottom of the foundation pit; The movable end of traversing hydraulic actuating cylinder and Liang Tiyi end are hinged, and the relative position according to fixed saddle on the said beam body is provided with movable saddle.

The high and low position of said each movable saddle is corresponding with the ladder raised position of each fixed saddle.

Track girder one side at the bottom of the said foundation pit is provided with hinged-support, and said traversing hydraulic actuating cylinder is hinged on the hinged-support.

Beneficial effect after the employing technique scheme is: a kind of coil of strip promotes step rate, through the present technique scheme, not only can satisfy the requirement that coil of strip in enormous quantities promotes or descends preferably; And it is simple in structure, practical, simple to operate; Degree of automation is high, maintenance convenient.

Among the figure, 1 fixed saddle, 2 track girders, 3 hinged-supports, 4 grounds are near coal-mine, at the bottom of 5 foundation pit, 6 wheels, 7 vehicle frames, 8 tracks, 9 beam bodies, 10 movable saddles, 11 promote hydraulic actuating cylinders, 12 traversing hydraulic actuating cylinders, 13 coil of strips.

The specific embodiment

To combine accompanying drawing that specific embodiment in the utility model is done further explain below.

Shown in Fig. 1-4; The coil of strip that the utility model relates to promotes step rate, includes fixed saddle 1, track girder 2, track 8 and mobile device, and said several fixed saddles 1 are arranged near coal-mine 4 both sides of ground; Two track girders that laterally arrange 3 are arranged at the bottom of the foundation pit 5; Said mobile device is made up of wheel 6 and vehicle frame 7, and wheel 6 is installed on the vehicle frame 7, and two groups of wheels 6 in two mobile devices are placed on respectively on two tracks 8 on the track girder 2; Also include beam body 9, movable saddle 10, promote hydraulic actuating cylinder 11, traversing hydraulic actuating cylinder 12; Said lifting hydraulic actuating cylinder 11 is fixed on the vehicle frame 7, and the movable end that promotes hydraulic actuating cylinder 11 is hinged on the bottom of beam body 9, and said traversing hydraulic actuating cylinder 12 is arranged at the bottom of the foundation pit 5 track girder 2 one sides; The movable end of traversing hydraulic actuating cylinder 12 and beam body 9 one ends are hinged, and the relative position according to fixed saddle 1 on the said beam body 9 is provided with movable saddle 10.

The high and low position of said each movable saddle 10 is corresponding with the ladder raised position of each fixed saddle 1.

5 track girder 2 one sides are provided with hinged-support 3 at the bottom of the said foundation pit, and said traversing hydraulic actuating cylinder 12 is hinged on the hinged-support 3.

The utility model makes progress the direction transmission when transporting iron coil of strip 13 at need of work; Lifting hydraulic actuating cylinder 11 in two mobile devices gives rise to beam body 9 coil of strip 13 times on the fixed saddle 1 that is positioned at low level, and movable saddle 10 holds up coil of strips 13, arrive the lifting summit that promotes hydraulic actuating cylinder 11 when lift height after; Traversing hydraulic actuating cylinder 12 promotes beam body 9; Beam body 9 stops to move through wheel 6 is moving to the next fixed saddle of alignment 1 position on the track girder 2 after, and movable saddle 10 is regained under the effect that promotes hydraulic actuating cylinder 11, and coil of strip 13 falls into a high-order fixed saddle 1; When coil of strip 13 is transported in the transmission of need of work downward direction; Opposite with above-mentioned action, principle of work is identical, no longer further gives unnecessary details at this.

The above is merely the preferable possible embodiments of the utility model, is not in order to limit the scope of the utility model.
