Abstract
The utility model relates to a pipe-passing guide head of a heat exchanger. The guide head comprises a main body, wherein an installation guide rod penetrates through the main body, one end of the guide rod is connected with a nut in a threaded mode, and a rubber pipe is sleeved at one end of the main body. The guide head is simple in structure and convenient to install. The guide head is placed into a heat exchange tube, and a conical body at one end of the guide rod is used for stretching the tail portion of the guide head. The rubber pipe can be axially contracted and radially inflated, so friction is increased, falling off is prevented, the guide head is not prone to falling off during the pipe passing process, and abrasion in the heat exchange tube is prevented from occurring.
Description
Technical field
The utility model relates to heat exchanger tube assembling field, relates in particular to a kind of leading head for through pipe of heat-exchanger.
Background technology
In the prior art, because the specification of heat exchanger constantly increases, cause heat exchanger inner tube bank length and weight constantly to increase, when adopting conventional method to install, because deadweight produces distortion, causing can't normal mounting in the lifting process for heat exchanger tube.Therefore can only will put into housing after tube sheet, the deflection plate assembling first, then carry out the blind operation of wearing, but because between each deflection plate, or have certain distance between deflection plate and tube sheet, and heat exchanger tube can't enter corresponding pore fast and accurately in the poling process, and there is error in assembling, cause the pore decentraction on the deflection plate, greatly improve rework rate, reduced production efficiency, affected manufacturing schedule.
The utility model content
The applicant provides a kind of leading head for through pipe of heat-exchanger simple in structure, easy for installation for above-mentioned existing shortcoming, has fast and accurately advantage of poling.
The technical scheme that the utility model adopts is as follows:
A kind of leading head for through pipe of heat-exchanger comprises main body, and the installation guide rod is run through in the inside of main body, and an end of guide rod is connected with nut thread, also is set with rubber tube in an end of main body.
Its further technical scheme is:
One end of described main body is cone, and the other end has " ten " font groove;
One end of described guide rod is cone.
The beneficial effects of the utility model are as follows:
The utility model is placed heat exchanger tube, utilize the cone of guide rod one end that afterbody of the present utility model is strutted, but because the rubber tube axial compression, be radially expanded, increasing friction force prevents slippage, make its difficult drop-off in the poling process, can prevent the inner appearance wearing and tearing of heat exchanger tube simultaneously.The cone of knife bar one end has reduced the contact area between heat exchanger tube and tube sheet, the baffle plate, has improved the poling accuracy rate, has reduced work difficulty.

Fig. 2 is the structural representation of the utility model main body.
Fig. 3 is the structural representation of the utility model guide rod.
Fig. 4 is structural representation of the present utility model.
Fig. 5 is that the utility model is at the structural representation of the course of work.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 4, the utility model comprises main body 2, and an end of main body 2 is cone, and the other end has " ten " font groove.As shown in Figure 2, run through installation guide rod 4 in the inside of main body 2, as shown in Figure 3, an end of guide rod 4 is cone.Such as Fig. 1, shown in Figure 4, an end of guide rod 4 is threaded with nut 1, also is set with rubber tube 3 in an end of main body 2.
Specific works process of the present utility model is as follows:
As shown in Figure 5, the utility model that assembles is inserted in the heat exchanger tube 5, the conical end of main body 2 and heat exchanger tube 5 one ends fit tightly, this moment, moving leader 4 strutted afterbody of the present utility model by guide rod 4, but the rubber tube axial compression, be radially expanded, increasing friction force prevents slippage.After strutting, rubber tube 3 props up the internal face of heat exchanger tube 5.Because an end of guide rod 4 has screw thread, and nut 1 is tightened, and prevents that guide rod 4 from moving.Nut 1 has also effectively avoided guide rod 4 to slip into the situation of heat exchanger tube 5 inside.
In the poling process, the cone of the utility model guide rod 4 contacts first the hole body edge, then slowly advances along the conical surface to enter hole body, and heat exchanger tube is slipped in the pore, bore a hole complete after, unclamp nut 1, knock guide rod 4 and extract the utility model.
The utility model is placed heat exchanger tube, utilize the cone of guide rod one end that afterbody of the present utility model is strutted, but because the rubber tube axial compression, be radially expanded, increasing friction force prevents slippage, make its difficult drop-off in the poling process, can prevent the inner appearance wearing and tearing of heat exchanger tube simultaneously.The cone of knife bar one end has reduced the contact area between heat exchanger tube and tube sheet, the baffle plate, has improved the poling accuracy rate, has reduced work difficulty.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and in the situation of basic structure of the present utility model, the utility model can be done any type of modification.
