Abstract
The utility model discloses a top rod trolley capable of quickly replacing a top rod, which solves the problem that present equipment cannot realize the quick replacing of the top rod. The top rod trolley comprises the top rod trolley (1), the top rod (3) and hydraulic cylinders (6). An L-shaped front tongue is fixedly arranged at the front face of the top rod trolley (1), and is composed of a groove body (4) and a horizontal bottom plate; the groove body (4) provided with a U-shaped groove is arranged at the front end, the horizontal bottom plate is fixedly connected with the groove body (4) and the top rod trolley (1), a tapered hole (7) is arranged at the front end of a hollow shaft (2) of the top rod trolley (1), the hydraulic cylinders (6) are respectively arranged on two upright posts of the groove body (4) with the U-shaped groove in a fixed manner, pressing rods (5) are fixedly arranged on output shafts of the hydraulic cylinders (6), and the two pressing rods (5) are respectively arranged on the two corresponding rear side faces of a flange head (9) of the top rod (3) in a movable manner. The top rod trolley greatly prolongs the service life of a tool and increases the production efficiency as well.
Description
Technical field
The invention belongs to metallurgy industry seamless steel tube production field, be specifically related to ejector rob trolley provided in a kind of large-size hot-rolled seamless steel pipe equipment.
Background technology
Ejector rob trolley provided and the push rod of big specification unit of the prior art is to adopt the cylinder bolt to connect, or adopt sphere positioning cylinder pin to connect, these connected modes only are applicable to that single push rod is rolling, only conveniently the top is changed, it is extremely inconvenient to change push rod, the quick circulation cooling of push rod can not be realized, the rolling mode of multi-functional machine can not be realized.
Summary of the invention
The invention solves existing equipment and can not realize the quick replacing of push rod, have the many technical problems of the slow fault of rhythm of production.
The present invention overcomes the above problems by following scheme:
A kind of rapidly replaced ejector rob ejector rob trolley provided, comprise ejector rob trolley provided 1, push rod 3 and hydraulic cylinder 6, described ejector rob trolley provided 1 front is set with L shaped preceding tongue, before this is L shaped tongue by the cell body 4 of the band U-lag that is in front end with fixedly connected the cell body 4 of band U-lag and constitute with ejector rob trolley provided 1 horizonal base plate, the front end of the hollow shaft 2 ejector rob trolley provided 1 is provided with taper hole 7, on two columns of the cell body 4 of described band U-lag, be set with hydraulic cylinder 6 respectively, be set with depression bar 5 on the output shaft of hydraulic cylinder 6, two depression bars 5 are movably arranged on respectively on the trailing flank of two correspondences of flange head 9 of push rod 3, the front of the flange head 9 of push rod 3 is set with the axis of cone 8,7 movable cooperations of taper hole that this axis of cone 8 and the front end of ejector rob trolley provided 1 hollow shaft 2 are provided with.
Described hydraulic cylinder 6 is provided with the hydraulic pressure electrical control gear.
The present invention can guarantee stability and the technological requirement when rolling, prolongs the cool time of push rod top again, has realized the rolling requirement of big unit multi-functional machine well.Thereby improved the service life of instrument greatly, improved production efficiency, rhythm of production is fast, and fault rate is low, reduces energy loss, improves the operating rate and the flexibility of unit.

The specific embodiment
A kind of rapidly replaced ejector rob ejector rob trolley provided, ejector rob trolley provided 1 hollow shaft 2 axle heads have a taper hole, ejector rob trolley provided front is set with L shaped preceding tongue, before this is L shaped tongue by the cell body 4 of the band U-lag that is in front end with fixedly connected the cell body 4 of band U-lag and constitute with ejector rob trolley provided 1 horizonal base plate, be set with hydraulic cylinder 6 respectively on two columns of the cell body 4 of U-lag, the depression bars 5 that two hydraulic cylinders 6 drive, push rod 3 afterbodys a stepped axis of cone 8 arranged.After push rod 3 moves on to the main mill line by transverse-moving mechanism, and the stepped axis of cone of push rod 3 afterbodys enters the U type groove of cell body 4.Two hydraulic cylinders 6 of ejector rob trolley provided 1 drive depression bar 5, and push rod 3 and hollow shaft 2 are compressed, and ejector rob trolley provided 1 advances under the effect of transmission system, and push rod 3 enters into preceding working position under ejector rob trolley provided 1 effect.Before the rolling beginning, hydraulic cylinder 6 drives depression bar 5 throws off with push rod 3, and push rod 3 drives ejector rob trolley provided 1 hollow shaft 2 rotations in the operation of rolling under the effect of roll.After rolling the finishing, ejector rob trolley provided 1 retreats under the effect of transmission system, the U type groove of ejector rob trolley provided 1 cell body 4 blocks the flange 9 of push rod 3, and finish and take off the pipe action, ejector rob trolley provided 1 behind the working position of back, transverse-moving mechanism shifts out roll line with push rod 3, and simultaneously new push rod 3 is sent into roll line by transverse-moving mechanism.This connecting mode has made things convenient for push rod line outer circulation cooling, also can realize simultaneously coming directly towards or the replacing of plug for big unit.
