A kind of structural representation of removing the device of flange pipeline internal bore welding slag that Fig. 1 the utility model specific embodiment 1 provides.
Among the figure:
1, a is partly overlapped in connection; 2, stud; 3, b is partly overlapped in connection; 4, cylinder body; 5, oil cylinder cover; 6, piston rod; 7, O RunddichtringO; 8, O RunddichtringO; 9, cutter head; 10, nut; 11, snap joint; 12, hydraulic line a; 13, Pressure gauge; 14, two-way manual pump.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through the specific embodiment; As shown in Figure 1; A kind of device of removing flange pipeline internal bore welding slag comprises two-way manual pump 14, is connected with two hydraulic line a12 and hydraulic line b on this two-way manual pump 14; Can be in cylinder body 4 input hydraulic pressure oil, seesaw with the piston rods 6 that promote in the cylinder body 4.
Align overlapping with the flange of cylinder block the flange of the flange pipeline of waiting to remove the endoporus welding slag; And on the outer rim side of two flanges of alignment, buckle connection half cover that both are fixed as one with it respectively, it is closely semi-circular for spill to connect half cover, is respectively connection and partly overlaps a1 and partly overlap b3 with being connected; Two behind the fastening connect half inner room the space are arranged; Connect half cover with two overlapping banjo clips among the recessed district that connects half cover, the stud bolt hole on two overlapping flanges coincides, and transversely also is provided with stud bolt hole what connect half cover; To connect half cover and be buckled on the flange, and connect and partly overlap a1 and partly overlap b3 and two flanges are fixed together with stud 2 with being connected; Oil cylinder cover 5 is installed outside cylinder body 4, is connected with hydraulic line a12 on the oil cylinder cover 5, snap joint 11 is installed on the hydraulic line b, snap joint 11 is fixed on the flange of cylinder body 4 from two spaces that connect between half cover.
In cylinder body 4, be provided with piston rod 6; The cutter head 9 that is used to remove welding slag is installed on the piston rod 6; Cutter head 9 has identical diameter with hole in piece part, cutter head 9 is installed on the step axle of piston rod 6 ends, tightens with nut 10; Cutter head 9 on the axle of the rank of centre, is not easy to produce loosening by fastening like this.
The utility model promotes piston rod 6 and is attached to oil cylinder cover 5 when work.The cutter head 9 that will be used to remove the gred is over against flange hole, in the pipeline hole that will remove the gred of packing into.Connection is partly overlapped 1 align the flange of flange pipeline and the flange of this device cylinder body 4 respectively, penetrate stud, be connected firmly with nut from stud bolt hole.Have two hydraulic line a and hydraulic line b on the two-way manual pump, hydraulic line a connects oil cylinder cover 5, and the other end is connected to two-way manual pressure test pump 14 and is with manometric interface; Hydraulic line b, an end are connected on the flange of cylinder body 4, and the other end is connected to not being with on the manometric interface of two-way manual pump 14.
Be provided with the oil pipe road in the oil cylinder cover 5, the both sides of the contact-making surface when oil cylinder cover 5 contacts with piston are respectively equipped with O RunddichtringO 7.Be provided with the oil pipe road in the end flange of cylinder body 4, in the cylinder body flange hole, be provided with O RunddichtringO 8, guarantee the sealing of oil circuit in the joint of oil pipe road and piston rod 6.
During use; At first guarantee the capacity machine oil of packing in the two-way manual pump 14; Pump rod with hand moving two-way manual pump 14 pumps pressure oil; Pressure oil gets into through pipeline in the rodless cavity of cylinder body 4, promotes piston rod 6 and moves forward, and moves forward thereby drive the cutter head 9 of piston rod 6 on connecting it.When through flange pipeline weld bond, cutting edge can be cut the welding slag of giving prominence to tube wall to pieces and remove, and has promptly realized removing the purpose of weld bond welding slag.
After the welding slag removing finishes, pull the reversal valve handle of two-way manual pump 14, make the switching-over of hydraulic oil oil inlet and outlet.Shake the pump rod of manual pump 14, pressure oil gets in the rod chamber of cylinder body 4, and piston rod 6 is by hydraulic drive, the withdrawal initial position.Lay down oil pressure, after manometric pointer makes zero, lay down stud 2, take off connection and partly overlap a1 and partly overlap b3, take off this device with being connected.
This apparatus structure is simple, and is easy to make, and hydraulic-driven is laborsaving quick again.The weldering of handling through this device slagging-off is flange directly, the inner hole wall smooth, and with normally not the flange internal diameter of weld be consistent.When handling the flange pipeline internal bore welding slag of single face welding double-faced forming, it is efficient and convenient that the utility model seems.
