Description
Technical field
The present invention relates to a kind of wiper and receive anticollision device, collision-prevention device, belong to the technology of oil and gas pipeline pigging operation
Field.
Background technology
Pipeline transportation is the Main Means of petroleum resources transport.And in pipe-line construction and running, be required for
Wiper is utilized to remove the water in pipeline and other impurity in time, to improve tube wall fineness and to manage defeated efficiency.?
After whole pigging operation completes, need to utilize ball collecting chamber to receive wiper.After wiper enters ball collecting chamber,
Due to wiper inertia, receive the reason such as ball technique, still having the wiper of certain speed, to clash into ball collecting chamber fast
Open blind plate, easily makes blind plate deform, and blind plate locking device seal fails causes security incident.Time serious
Even more so that blind plate ruptures, cause the personal injury of operator.
Current solution is to install rubber tyre in ball collecting chamber additional.But the cushioning effect of rubber tyre has
Limit, and is easily hit partially by wiper, impact receipts ball, so, there is potential safety hazard in this method, and with
Increasing of time of pigging, this hidden danger can be continuously increased.
Therefore, in ball operation received by wiper, just can eliminate what fast opening blind was impacted by wiper in the urgent need to a kind of
Collision prevention device.
Summary of the invention
The invention aims to overcome prior art to be difficult to eliminate the wiper impact to fast opening blind, and peace
The problem that overall coefficient is low, it is provided that a kind of wiper receives anticollision device, collision-prevention device, uses this invention can eliminate wiper pair
The impact of fast opening blind, ensures the safety receiving ball operation.
The technical solution adopted in the present invention is:
One wiper of the present invention receives anticollision device, collision-prevention device, mainly by front anti-raming, T-shaped screw rod, rotary decelerator,
First spring, base, fixing bolt are constituted.Before described, the anti-external diameter ramed matches with ball collecting chamber inwall, and
Its front end is provided with polyurethane discs；Described T-shaped screw rod before being fixed on anti-ram on；Described rotary decelerator center
There is the hole of band spiral lamination, coordinate with T-shaped screw flight；Described first spring one end is fixed on the end of T-shaped screw rod
Portion, its other end is fixed on base, and arranges with ball collecting chamber axial symmetry；Fast with on ball collecting chamber of described base
Open blind plate is affixed by fixing bolt.
Described rotary decelerator, is mainly made up of brake pad, bar, flat board, the second spring B, sleeve, disk.
Circumferentially fixed six sleeves in described disk side edge, each sleeve angle each other is 60 °；Described set
Cylinder inner bottom part has the second spring, the second spring one end to be fixed on disk, and the other end is fixed on flat board；Described
Flat board coordinates with the big splaying of sleeve；Described bar one end is fixed on flat board, and the other end is fixed on brake pad
Together；The material of described brake pad is polyurethane, and its lower end is connected with sleeve matched in clearance；When device puts into receipts
After in ball cylinder, under the effect of the second spring force, the top of brake pad and ball collecting chamber inwall interference fit.
By coordinating of screw rod and rotary decelerator, the effect of impact of straight line is converted into the rotation of rotary decelerator
Effect, utilizes rotary decelerator to rotate and drives the method for brake pad friction ball collecting chamber inwall to carry out shock absorbing, this
Sample makes to collide produced energy and is buffered and absorbs.
The present invention has the advantage that and provides the benefit that: 1, anticollision device, collision-prevention device simple in construction of the present invention, can be by
The energy clashed into converts and absorbs；2, anticollision device, collision-prevention device of the present invention only need to be arranged on ball collecting chamber fast opening blind
Before, it is adaptable to the reception of dissimilar wiper is crashproof；3, anti-collision effect is good, can eliminate wiper to receiving ball
The impact of cylinder fast opening blind, significant to the safety guarantee receiving ball operation.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of wiper of the present invention receives anticollision device, collision-prevention device；
Fig. 2 is the rotary decelerator structural representation of the present invention.
In figure: 1. prevent before raming, 2.T shape screw rod, 3. rotary decelerator, 4. the first spring, the 5. end
Seat, 6. brake pad, 7. bar, 8. flat board, 9. the second spring, 10. sleeve, 11. disks, 12. is solid
Determine bolt, 13. fast opening blinds.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, one wiper of the present invention receives anticollision device, collision-prevention device, mainly by front anti-raming 1, T
Shape screw rod 2, rotary decelerator the 3, first spring 4, base 5, fixing bolt 12 are constituted.Described front crashproof
The external diameter of 1 matches with ball collecting chamber inwall, and its front end is provided with polyurethane discs, has both played preliminary buffering and has hit
The effect hit, turn avoid due to the principle of active force Yu counteracting force so that wiper is caused by anticollision device, collision-prevention device
Infringement；Described T-shaped screw rod 2 is anti-before being fixed on rams on 1；There is band spiral lamination at described rotary decelerator 3 center
