Description
Technical field
A kind of grinding apparatus is the utility model is related to, the socket steel ring during especially a kind of PCCP whitewashings is synchronously polished
Equipment.
Background technology
PCCP（Prestressed concrete cylinder pipe）Spray operation after silk is twined, needs to spray a water for the PCCP of non-senior engineer pressure
Cement mortar protective layer, and major diameter, the PCCP of senior engineer's pressure, need to can be only achieved in tube core outer wall two layers of compressor wire of winding and hold
By the intensity of internal pressure.After the completion of every layer of steel wire winding, one layer of mortar cover is sprayed, dry mortar is by mortar coater with 37
The speed of meter per second is ejected into pipe outer surface, and PCCP tubing at the uniform velocity rotates while injection, completes the making work of mortar cover
Sequence.In the process, since mortar sprays at a high speed, mortar is caused to be attached on pipeline socket steel ring, and the height of the second gunite
Work pressure PCCP sockets steel ring can adhere to more cement mortar, produce harmful effect to processes such as ensuing polishings, seriously drag
Slow rhythm of production, influences pipeline beauty.For this reason, it may be necessary to corresponding synchronization socket sanding apparatus, so as to while completing to whitewash
Eliminate attachment of the mortar to socket steel ring.
At present, the shared two ways of PCCP bell and spigots polishing is directed to, when, by the way of manual polishing, which
Special sanding machine is held by the worker at tube core both ends, is polished tube core receptacle wall and bellmouth inner wall.This kind produces
Mode has the following disadvantages：1st, polishing is less efficient, 2, need worker's number more, 3, polishing precision be difficult to be precisely controlled,
4th, there are security risk in bruting process；Second, using dedicated large-scale mouth of pipe grinding apparatus, such as Application No.
201410462243.7, a kind of entitled PCCP pipes sanding apparatus, it is embodied and throws away that there are following defect：1st, equipment volume
Greatly, ground and built-in fitting need to be made in advance, taken up a large area, the cycle of putting into production is longer, 2, equipment for it is fixed, it is necessary to row
The cooperation of the equipment such as car could use, investment it is larger, 3, equipment be difficult to move, operation flexibility ratio it is low, it is impossible to meet production scene
The requirement of flexibility.
This project device miniaturization is studied by domestic Ye You mechanisms, such as Patent No. 201420201171.6, name
The referred to as cleaning grinding apparatus of PCCP tubing socket joint mouth circle, in specific implementation, there are following defect for it：When equipment is in tube core
Wall does circumferential movement, after pipe centerline（When having moved to 90 ° of positions of tube core level from the position of 0 ° of bottom）Still need to
Human assistance could polish completion, therefore operation still suffers from inconvenience.
