Abstract
A kind of heat exchanger poling guiding device, this guiding device comprises guide head, swingle, sleeve, draws tablet, flexible particle thing, capping; Described swingle tail end is affixed draw tablet after be jointly placed in sleeve, and the tail end of sleeve is closed by capping after filling flexible particle thing, and the other end of this swingle is connected with the guide head be placed in outside sleeve; The sleeve surface that described swingle rear end surface has swivelling chute and the suitable position of this swivelling chute has hole slot.The utility model adopts flexible particle thing to contact with heat exchanger tube, has locking effect good, does not damage the effect of heat exchanger tube.
Description
Technical field
The utility model relates to a kind of heat exchanger poling accessory.
Background technology
At present, when pipe heat exchanger tube bank manufactures, need first by tube sheet, deflection plate, pull bar etc. have first been assembled, then carry out that poling is blind wears operation.But due to many factors such as machined, welding, assemblings, cause tube sheet and deflection plate, decentraction between deflection plate, therefore heat exchanger tube need be guided to bore a hole by device during poling operation, necessity also needs to knock with mallet.Take the lead due to the impact by mallet, cause guiding device and heat exchanger tube to depart from.So must appropriate design poling guiding device, adopt that correct poling technique guarantee poling is working properly to carry out.
Utility model content
The utility model provides a kind of heat exchanger poling guiding device, has locking effect good, does not damage the effect of heat exchanger tube.
The technical scheme of concrete employing is as follows:
A kind of heat exchanger poling guiding device, this guiding device comprises guide head, swingle, sleeve, draws tablet, flexible particle thing, capping; Described swingle tail end is affixed draw tablet after be jointly placed in sleeve, and the tail end of sleeve is closed by capping after filling flexible particle thing, and the other end of this swingle is connected with the guide head be placed in outside sleeve; The sleeve surface that described swingle rear end surface has swivelling chute and the suitable position of this swivelling chute has hole slot.
Described sleeve surface has hole slot, and hole slot afterbody side band is gradient, is beneficial to flexible particle thing and exits hole slot.
Describedly draw tablet in the shape of a spiral.When rotating swingle, flexible particle thing is driven to enter or exit swivelling chute.
The utility model mainly utilizes swingle to rotate in sleeve, is squeezed between sleeve and heat exchanger tube, thus guiding device and heat exchanger tube are well locked by moulding flexible particle thing in sleeve.Simple and the difficult drop-off of taking the lead in poling process of the utility model structure, prevents heat exchanger tube inside from scratching simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model swingle modular construction schematic diagram;
Fig. 3 a is that the utility model sleeve laterally cuts open schematic diagram;
Fig. 3 b be in Fig. 3 a A-A to cut-away view
Fig. 3 c is Fig. 3 a interior joint I partial enlarged drawing.
Detailed description of the invention
below in conjunction with accompanying drawing, the utility model and effect thereof are further illustrated.
As shown in Figure 1, first by swingle 2 with draw tablet 4 and be consolidated, again it is penetrated from sleeve 3 afterbody, and the side of band pin hole is exposed from sleeve 3 front portion, swingle and guide head 1 fit together by recycling connecting pin, then add flexible particle thing 5 from sleeve 3 afterbody, then capping 6 is connected with sleeve 3 by screw thread.Its specific works process is as follows:
The guiding device assembled is inserted in heat exchanger tube, sleeve 3 end step and heat exchanger tube end face are fitted tightly, again guide head 1 and sleeve 3 are compressed and rotary steering head 1, thus driven rotary bar 2, draw tablet 4 to rotate, drawing when tablet 4 rotates introduces in the swivelling chute of swingle 2 by the flexible particle thing 5 being stored in sleeve 3 afterbody, and flexible particle thing 5 is driven toward guide head 1 side, when arriving the hole slot place on sleeve 3 when flexible particle thing 5, flexible particle thing 5 will insert fluting position, continue rotary steering head 1, flexible particle thing 5 will fill up and compress in groove, thus the object that arrival heat exchanger tube inwall and guiding device are combined closely.Backwards rotation guide head 1 is only needed to unclamp guiding device at the end of poling.
