Abstract

The utility model discloses a machine cover shifting out device which comprises an upper machine cover (1) and a lower machine frame (2). The utility model is characterized in that the upper machine cover (1) is provided with a guide rail sliding frame (4), and the lower machine frame (2) is provided with a guide rail seat (3). A supporting seat (14) is arranged below the guide rail seat (3) which is provided with guide rails (8), a driven sprocket (5) and a driving sprocket (9). An overweight pitch chain (7) is arranged between the driving sprocket (9) and the driven sprocket (5), and the driving sprocket (9) is connected with a motor (11) by a speed reducer (10). One end of the driving sprocket (9) on the guide rail seat (3) is provided with a tensioning cylinder (12). The utility model is a device having the advantages of automation, accuracy, time saving, high efficiency and high safety in the shifting out mode of the machine cover.

Description

A kind of cover moving-out device

Technical field:

The utility model relates to tube rolling, planisher technical field, is a kind of device that spurs tube rolling, the slippage of smooth unit cover specifically.

Background technology:

Produce seamless steel pipe at present, tube rolling, planisher are the main equipments of producing hot rolled seamless steel tube, in the processing process because roll wear or change specification, need cover is shifted out, now generally adopt the method for overhead traveling crane and steel wire rope pulling, cover is shifted out, this method poor safety performance and wasting time and energy, efficient is low.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of cover moving-out device is provided, and mainly solves existing cover and shifts out poor safety performance, wastes time and energy and inefficient problem.

To achieve these goals, the utility model is achieved in that a kind of cover moving-out device, it comprises upper-cover 1 and lower bearing bracket 2, its special character is to establish guide rail balladeur train 4 on upper-cover 1, on lower bearing bracket 2, establish track base 3, divide into bearing 14 at track base 3, on track base 3, establish guide rail 8, on track base 3, establish by movable sprocket 5 and drive sprocket 9, establish overweight pitch chain 7 at drive sprocket 9 and between by movable sprocket 5, drive sprocket 9 is connected with motor 11 by reductor 10, and an end of the drive sprocket 9 on track base 3 is established tensioning cylinder 12.

A kind of cover moving-out device of the present utility model is established block 13 on its described track base 3; Establish chain tension screw mandrel 6 on the described guide rail balladeur train 4; Described reductor 10 is a worm reduction gear; Described motor 11 is a hydraulic motor.

Compared with the prior art a kind of cover moving-out device described in the utility model has following good effect: owing to installed a kind of mechanical device additional on cover and frame, make the automation of cover mechanically moving, have accurately, security performance is high, save the operating time, reduce manpower and working strength of workers, improved production efficiency simultaneously.

Description of drawings:

Fig. 1---structural representation of the present utility model.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of cover moving-out device of the utility model in detail.

Embodiment 1, referring to Fig. 1, be processed into track base 3 and guide rail balladeur train 4, fixed installation bearing 14 below track base 3, be used for supporting guide seat 3, at track base 3 upper mounting rails 8, and on track base 3, fixedly mount by movable sprocket 5 and drive sprocket 9, overweight pitch chain 7 is installed at drive sprocket 9 and between by movable sprocket 5, drive sprocket 9 is connected with hydraulic motor 11 by worm reduction gear 10, one end of the drive sprocket 9 on track base 3 is installed tensioning cylinder 12, can totally adjust the length of overweight pitch chain 7; Chain tension screw mandrel 6 is installed on guide rail balladeur train 4; be used for overweight pitch chain 7 is finely tuned, guide rail balladeur train 4 is fixedly mounted on the upper-cover 1, track base 3 is fixedly mounted on the lower bearing bracket 2; fixed installation block 13 on track base 3 is used for position limitation protection simultaneously.

Embodiment 2, with embodiment 1, difference is when equipment is big, article one, when the power of lifting pitch chain is not enough, can adopt the both sides of worm reduction gear 10 to drive two drive sprockets 9 simultaneously, the track base 3 of the moving-out device of opposite side is also fixedlyed connected with upper-cover 1 with lower bearing bracket 2 respectively simultaneously with guide rail balladeur train 4.

Embodiment 3, when equipment is bigger, can adopt the two group devices identical with embodiment 2 to carry out shifting out of upper-cover simultaneously.

A kind of cover moving-out device described in the utility model; during use; motor drives drive sprocket by reductor and rotates, and rotates thereby drive driven sprocket, makes chain sliding guides balladeur train; thereby drive upper-cover slippage on guide rail; upper-cover is shifted out, when the guide rail balladeur train moves to the block place, under the position-limiting action of block; cover is no longer mobile, carries out position limitation protection.
