Abstract
The utility model discloses a sizing vertical roll shaft dismounting apparatus. The apparatus comprises a supporting frame and a conveying device. The supporting frame is a double-layer structure, and the upper layer is fixedly provided with a downward-pressing device while the lower layer is a supporting platform. A sizing vertical roll is disposed on the conveying device. When the sizing vertical roll is conveyed to the supporting platform, a pressing rod of the downward-pressing device corresponds to the center of a vertical roll shaft of the sizing vertical roll and presses downwards to dismount the vertical roll shaft from the sizing vertical roll, and the vertical roll shaft drops into the conveying device. The apparatus has a simple structure. With the design of the conveying device for conveying the sizing vertical roll shaft and the downward-pressing device for applying pressure onto the sizing vertical roll shaft to dismount the roll shaft, the working mode of complete manual dismounting is changed thoroughly and the automatic operation is realized, thereby reducing the labor intensity of workers, increasing the work efficiency, and preventing potential safety hazards brought by manual dismounting. Accordingly, the safe, simple, quick, and highly-efficient dismounting of the sizing vertical roll shaft, in interference fit, of a large tube welding machine set is realized.
Description
Technical field
The utility model relates to steel pipe's production equipment, specifically a kind of sizing vertical roll shaft attaching/detaching apparatus for large-scale welded tube unit interference fit.
Background technology
At present, the sizing vertical roll shaft of large-scale welded tube unit interference fit is all used artificial dismounting, its process is: sizing vertical roll shaft and sizing edger roll that interference fit is housed are together seated on Special-purpose bench, manually stand on stand and carry out gravity hammering with copper rod, sometimes on vertical roll shaft, pad sleeper sledgehammer and carry out dismounting.In whole process, due to manual operation, the length that expends time in, takes efforts large, and potential safety hazard is large, inefficiency, and labour intensity is high.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of sizing vertical roll shaft attaching/detaching apparatus, makes the replacing simple and fast of sizing vertical roll shaft, and automation mechanized operation is time saving and energy saving, saves artificial, safe.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of sizing vertical roll shaft attaching/detaching apparatus, include bracing frame and conveying device, support frame as described above is set to double-decker, upper strata is fixedly installed hold-down devices, and lower floor is set to support platform, and sizing edger roll is positioned in conveying device, walk to support platform place, the depression bar of hold-down devices is corresponding with the vertical roll shaft center of sizing edger roll, and depression bar presses down vertical roll shaft is split out in sizing edger roll, falls in conveying device.
Described conveying device adopts delivery track car, and support frame as described above bottom is provided with corresponding track.
The support platform of support frame as described above is arranged on the both sides of bracing frame, and has inside groove, and the top panel of described conveying device and described groove are suitable.
Described hold-down devices is set to hydraulic jack and hydraulic control device, and the piston rod of described hydraulic jack is as depression bar.
The utility model is simple in structure, design for delivery of the conveying device of sizing vertical roll shaft with for exerting pressure with the hold-down devices of being pulled down to sizing vertical roll shaft, thoroughly change the mode of operation of completely artificial dismounting, realize automation mechanized operation, alleviate labor strength, reduce artificial, improve operating efficiency, it is time saving and energy saving really to accomplish, and the potential safety hazard of having avoided artificial dismounting to exist, has realized the safe, simple and easy, quick and efficient of sizing vertical roll shaft dismounting to large-scale welded tube unit interference fit.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the lateral plan of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Be illustrated in figure 1 a specific embodiment of the present utility model, this sizing vertical roll shaft attaching/detaching apparatus, include bracing frame 4 and conveying device 2, support frame as described above 4 is set to double-decker, and upper strata is fixedly installed hold-down devices 5, lower floor is set to support platform, sizing edger roll 1 is positioned in conveying device 2, walks to support platform place, and the depression bar of hold-down devices 5 is corresponding with vertical roll shaft 7 centers of sizing edger roll 1, depression bar presses down vertical roll shaft 7 is split out in sizing edger roll 1, falls in conveying device 2.
As preferred mode, described conveying device 2 adopts delivery track car, and support frame as described above 4 bottoms are provided with corresponding track 3.
In order to realize the more stable of disassembly process, be arranged on the both sides of bracing frame as the support platform of preferred support frame as described above 4, and there is inside groove 41, the top panel of described conveying device 2 and described groove 41 are suitable.
In the present embodiment, described hold-down devices 5 is set to hydraulic jack and hydraulic control device, and the piston rod of described hydraulic jack is as depression bar.Certainly; also can adopt the mode of air pressure control; realize the lower compression functions to sizing vertical roll shaft by cylinder and piston rod; also can adopt elastic device; the main purpose of this device is that the active force of realizing mechanical device generation comes to lower compression sizing vertical roll shaft 7 in a word; make it depart from sizing edger roll 1, reach the object splitting out, the hold-down devices that can realize this function should be all protection domain of the present utility model.
In the present embodiment, first the sizing edger roll 1 use overhead traveling crane that vertical roll shaft 7 is housed is winched in sizing edger roll conveying device 2, manually promote gently sizing edger roll conveying device 2, sizing edger roll is transported to support platform place by guide rail 3, sizing vertical roll shaft 7 centers and cylinder piston rod center are just aligned, open hydraulic control device 6, under the active force of hydraulic jack, be easy to the sizing vertical roll shaft of interference fit to pull down, sizing vertical roll shaft 7 drops in conveying device 2 automatically, then with manually gently sizing edger roll 1 being pulled out together with vertical roll shaft 7, hang out sizing edger roll 1 and vertical roll shaft 7 with overhead traveling crane again.
The sizing vertical roll shaft loading procedure of interference fit and to split out process just contrary.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
