Description
Technical field
The utility model belongs to a kind of cold exchange device U-tube applied to industries such as petroleum, chemical industry, metallurgy, electric power
Rust removalling equipment belongs to field of machining.
Background technique
U-tube is bent by straight tube, by U pipe bend and single tube pressure testing after, it may appear that the case where returning rust, so U
The derusting of shape tube end outer wall can only be carried out before the tube bank poling of cold exchange device, in descaling process, since U-tube structure is special
Property, mostly use manual sanding machine to derust greatly, the position of derusting, depth are grasped by arm strength completely, and derusting is not high, rapid wear
Hurt U-tube, production efficiency is too low.
Utility model content
The goal of the invention of the utility model is: improving derusting, reduces labor intensity, enhances production efficiency.
To achieve the above object, the utility model uses a kind of following design scheme: U-tube end outer wall derusting dress
It sets, is mainly made of pedestal, motor, sized flap wheel, positioning jackscrew, extension spring, locating support, bearing, support platform, the bottom
It is symmetrical arranged 2 movable screw keyholes, 2 fixed bolt holes and base center on seat, bearing hole, the motor setting 2 are set
Platform installs sized flap wheel respectively, is connected respectively by locating support using movable screw keyhole, the fixed bolt hole on bolt and pedestal
Fixation is connect, described bearing one end is welded in the bearing hole on pedestal, and the other end is welded and fixed with support platform, the positioning top
Silk one end is withstood on the locating support of movable end, and the other end is fixed on the base, and one end of the extension spring is pulled in movable end
Locating support on, the other end is fixed on the base.
The utility model is characterized by rotating base, comprehensive to U-tube end outer wall can derust,
Become smaller additionally due to the sized flap wheel being mounted on motor can generate consumption in descaling process, is moved by adjusting positioning jackscrew
Locating support changes the distance between two sized flap wheels to reach, and guarantees that outer surface of steel tube comes into full contact with sized flap wheel, reaches
To continuous derusting purpose, at the same the extension spring being arranged on pedestal guarantee to adjust by positioning jackscrew between two sized flap wheels away from
From when, more steadily and precisely.
Utility model has the advantages that descaling process is avoided to damage U-tube, derusting area is big, derusts uniformly and without dead
Angle, the beautiful appearance that has many advantages, such as to derust, work efficiency is high, device structure is simple, handling ease, easy to operate, it is ensured that cold
The tube head welding quality of U-tube and tube sheet in exchange device.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of U-tube end outer wall derusting device of the utility model.
Fig. 2 is a kind of holes on base schematic diagram of U-tube end outer wall derusting device of the utility model.
Including: pedestal 1, first motor 2, the second motor 3, sized flap wheel 9, positioning jackscrew 7, extension spring 8, positioning branch
Frame 6, bearing 5, support platform 4 are wherein opened movable screw keyhole 1-1, movable screw keyhole 1-2, fixed bolt hole 1-3, are consolidated on pedestal 1
Determine bolt hole 1-4 and base center setting bearing hole 1-5.
Specific embodiment
Shown in attached drawing 1, attached drawing 2, a kind of U-tube end outer wall derusting device, mainly by pedestal 1, first motor 2, second
Motor 3, sized flap wheel 9, positioning jackscrew 7, extension spring 8, locating support 6, bearing 5, support platform 4 form, wherein on pedestal 1
It is symmetrical arranged movable screw keyhole 1-1, movable screw keyhole 1-2, fixed bolt hole 1-3, fixed bolt hole 1-4 and base center are set
Set bearing hole 1-5.First motor 2, the second motor 3 are arranged symmetrically, install sized flap wheel 9 respectively, first motor 2 passes through 2
Locating support 6 is connected and fixed using bolt and movable screw keyhole 1-1, the fixed bolt hole 1-3 on pedestal 1, and the second motor 3 passes through
2 locating supports are connected and fixed using bolt and movable screw keyhole 1-2, the fixed bolt hole 1-4 on pedestal 1, the weldering of 5 one end of bearing
It is connected in the bearing hole 1-5 on pedestal 1, the other end is welded and fixed with support platform 4.The one end for wherein positioning jackscrew 7 withstands on work
On the locating support 6 of moved end, the other end is fixed on pedestal 1, and one end of extension spring 8 is pulled on the locating support 6 of movable end,
The other end is fixed on pedestal 1.By adjusting positioning jackscrew 5 come running fix bracket 6, thus reach two sized flap wheels of change it
Between distance, guarantee outer surface of steel tube come into full contact with sized flap wheel.
Implementation below by taking the derusting of the U-tube end outer wall of an outer diameter 25mm as an example, in conjunction with attached drawing to the utility model
Mode is illustrated.
Embodiment: after derusting device is completed, one end of U-tube is inserted into for the U-tube of a piece outer diameter 25mm of processing
In bearing hole 1-5, after adjusting the distance between two sized flap wheels and steel pipe by positioning jackscrew 7, motor switch, derusting are opened
Start, convenient and efficient to the comprehensive derusting of U-tube pipe end outer wall by manual Rotating with Uniform pedestal 1, derusting is uniform.
