Abstract
A method for replacing a servo cylinder of a seamless steel tube continuous rolling mill comprises the following steps: 1) assembling a replacing device comprising a base, a hydraulic cylinder, an angle adjusting device and a tray; 2) hoisting the replacing device to a track of a rolling mill tunnel, and then sliding the replacing device to a dismounting or mounting position of the servo cylinder; 3) the left and right positions of the replacing device are adjusted to coincide with the center of the servo cylinder to be replaced; 4) adjusting the tray to the installation angle of the servo cylinder by using an angle adjusting device; 5) the length of the hydraulic cylinder is changed, so that the tray at the tail end of the hydraulic cylinder can support the bottom of the servo cylinder; 6) and continuously extending the length of the hydraulic cylinder, ejecting the servo cylinder out of the mounting hole in the outer wall of the continuous rolling mill tunnel, and transporting the detached servo cylinder out of the rolling mill tunnel by using a replacing device. The invention can effectively solve the problem of the falling off of the servo cylinder, reliably ensures the personal safety of constructors and the equipment safety, and has the advantages of simple operation, low labor intensity and high safety. 3. The construction speed is fast, and is efficient.
Description
Technical field:
The invention belongs to a kind of tandem mill installation and maintenance field, particularly a kind of replacing options of seamless steel pipe rolling mill servoBcylinder.
Background technology:
In tandem mill, servoBcylinder is core component, is the final executive component of servo press down system.The external form of servoBcylinder is column type, and piece weight is large, is embedded on milling train tunnel outer wall, and is angle of inclination with tunnel.
When removing servoBcylinder, restricting by site environment, usually using the instruments such as jack to remove, but easily servoBcylinder obscission occurring, and the manpower needed and aid many.When installing servoBcylinder, because servoBcylinder setting angle requires accurately, making to utilize the instruments such as common jack, steel wire rope in an installation, but not easily reaching angle requirement, during installation fee, effort.
Summary of the invention:
Object of the present invention is just to overcome above-mentioned the deficiencies in the prior art, and provides a kind of replacing options of seamless steel pipe rolling mill servoBcylinder, and the method utilizes hydraulic cylinder operation, simple to operate, labour intensity is low, can facilitate the installation and removal of servoBcylinder.
As above conceive, technical scheme of the present invention is: a kind of replacing options of seamless steel pipe rolling mill servoBcylinder, is characterized in that: comprise the steps:
1) assembling comprises the more changing device of pedestal, hydraulic cylinder, angle regulator and pallet, pedestal is provided with support, hydraulic cylinder and angle regulator are arranged on this support respectively, and hydraulic cylinder front end is connected with angle regulator, and hydraulic cylinder end is fixed with pallet; Described base bottom two ends are shaped with draw-in groove; Draw-in groove is equipped with locking device;
2) by the more changing device handling of seamless steel pipe rolling mill servoBcylinder on the track in milling train tunnel, then by its slippage to the dismounting of servoBcylinder or installation site;
3) left and right position of more changing device is adjusted, make the left and right position of more changing device and the servoBcylinder center superposition needing to change, with the draw-in groove at the fastening bolt clamping pedestal two ends on locking device, guarantee that changing device is clamped on the track in tandem mill tunnel; This draw-in groove is arranged on tandem mill tunnel inner orbit;
4) with angular adjustment apparatus, pallet is adjusted to the setting angle of servoBcylinder;
5) change the length of hydraulic cylinder, make the pallet of its end just can hold the bottom of servoBcylinder;
6) then continue to extend the length of hydraulic cylinder, servoBcylinder is ejected from the installing hole of tandem mill tunnel outer wall, and with more changing device, the servoBcylinder of dismounting is transported milling train tunnel.
The present invention has following advantage and good effect:
1, the present invention can solve servoBcylinder obscission effectively, the personal safety of Reliable guarantee workmen and device security.
2, the present invention utilizes hydraulic cylinder operation, simple to operate, labour intensity is low, and security is high.
3, speed of application of the present invention is fast, and efficiency is high.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of more changing device;
The using state figure that Fig. 2 is operating position of the present invention when being horizontal level;
The using state figure that Fig. 3 is operating position of the present invention when being obliquity.
Detailed description of the invention:
Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
As shown in Figure 1: a kind of more changing device of seamless steel pipe rolling mill servoBcylinder, comprise pedestal 1, hydraulic cylinder 2, angle regulator 3 and pallet 5, pedestal is provided with support 4, hydraulic cylinder and angle regulator are arranged on this support respectively, hydraulic cylinder front end is connected with angle regulator, and hydraulic cylinder end is fixed with pallet; Described base bottom two ends are shaped with draw-in groove 7, draw-in groove are equipped with locking device 6.
Hydraulic cylinder on described pedestal is by the flexible change pallet of self and the distance of servoBcylinder installation site.The length of described angular adjustment apparatus can regulate, by changing the angle of inclination of its length adjustment hydraulic cylinder and pallet.Described pallet is in order to hold servoBcylinder that is to be removed or that install.Described locking device has fastening bolt, and the draw-in groove of clamping pedestal, does not allow it to be free to slide on the guide rail in tandem mill tunnel.
The replacing options of the more changing device of above-mentioned seamless steel pipe rolling mill servoBcylinder, comprises the steps:
1) first by the more changing device handling of seamless steel pipe rolling mill servoBcylinder on the track in milling train tunnel, then by its slippage to the dismounting of servoBcylinder or installation site;
2) left and right position of more changing device is adjusted, make the left and right position of more changing device and the servoBcylinder center superposition needing to change, with the draw-in groove at the fastening bolt clamping pedestal two ends on locking device, guarantee that changing device is clamped on the track in tandem mill tunnel; This draw-in groove is arranged on tandem mill tunnel inner orbit;
3) with angular adjustment apparatus, pallet is adjusted to the setting angle of servoBcylinder;
4) change the length of hydraulic cylinder, make the pallet of its end just can hold the bottom of servoBcylinder;
5) then continue to extend the length of hydraulic cylinder, servoBcylinder is ejected from the installing hole of tandem mill tunnel outer wall, and with more changing device, the servoBcylinder of dismounting is transported milling train tunnel.
During installation, more changing device is parked in outside tunnel, servoBcylinder to be installed by after handling pallet, then by more changing device slippage to the installation site in tunnel, lock and more adjust angle after changing device, by change hydraulic cylinder extended length can successfully by servoBcylinder top to installation site.
