Abstract
The invention discloses a guide head penetrating through a heat exchange tube. The guide head comprises a conical head, the rear end of the conical head is provided with a connection rod, the two sides of the connection rod are symmetrically provided with a pair of longitudinal receding grooves concave inwards, the inside of each receding groove is provided with a spring piece, each spring piece comprises a spring piece body, the rear end of each spring piece body is provided with a spring piece tail portion, each spring piece tail potion is fixedly arranged in the corresponding receding groove and at the rear end of the connection rod, and each spring piece body is of an arc shape protruding out of the corresponding receding groove. When the tube is penetrated, the spring piece bodies recede to the corresponding receding grooves after being extruded by the inner wall of the heat exchange tube and are clamped on the inner wall of the heat exchange tube. The guide head has the advantages that the guide head is convenient to use and reliable, and even if the heat exchange tube is shaken or knocked during tube penetrating, the guide head can not be separated from the heat exchange, so that tube penetrating efficiency of the heat exchange tube is improved, and the guide head is suitable for heat exchange tubes of various diameters.
Description
Technical field
The present invention relates to heat exchanger guiding device for pipe penetration, be specifically related to heat exchanger tube poling guide head.
Background technology
While making heat exchanger, heat exchanger tube need to be located on tube sheet and deflection plate, due to the aperture of pore on tube sheet and deflection plate and the caliber gap of heat exchanger tube less, and there is assembling tolerance after tube sheet and deflection plate assembling, so heat exchanger tube is relatively difficult to through pore when actual wearing, conventionally poling guide head need to be set in the end of heat exchanger tube, the structure of traditional poling guide head comprises: conical nose, the rear end of conical nose is provided with connecting rod.While wearing, heat exchanger tube is directly sleeved on connecting rod to matched in clearance between connecting rod and heat exchanger tube.Owing to wearing in process, heat exchanger tube can be vibrated and be knocked, and easily comes off like this between heat exchanger tube and poling guide head, falls into after can causing poling guide head to come off in equipment and is difficult to take out.
Summary of the invention
The object of the invention is: provide a kind of and can effectively prevent in wearing process heat exchanger tube and poling guide head comes off, and can assist the heat exchanger tube poling guide head of raising poling efficiency.
For achieving the above object, the technical solution used in the present invention is: heat exchanger tube poling guide head, comprise conical nose, the rear end of conical nose is provided with connecting rod, the bilateral symmetry of connecting rod offers a pair of longitudinal setting, and the inside recessed groove of dodging, this is respectively arranged with a spring leaf to dodging in groove, each spring leaf includes spring leaf body, the rear end of each spring leaf body is provided with spring leaf afterbody, each spring leaf afterbody is all fixedly mounted on the rear end that correspondence is dodged groove inside connecting rod, each spring leaf body is all and protrudes from correspondence and dodge the circular-arc of groove, during poling, a pair of spring leaf body be subject to after the extruding of heat exchanger tube inwall can be respectively to dodging of correspondence in groove, dodge and block on the inwall of heat exchanger tube.
Further, aforesaid heat exchanger tube poling guide head, wherein, each rear end of dodging groove inside connecting rod is provided with the installation base of mounting spring sheet afterbody.
Further, aforesaid heat exchanger tube poling guide head, wherein, the front end of each spring leaf body all stretches to corresponding dodging in groove and leave and dodge gap with this bottom of dodging groove.
Advantage of the present invention is: simple and practical, by the bilateral symmetry at connecting rod, spring leaf is set and dodges groove, during poling, spring leaf body be subject to the extruding of heat exchanger tube inwall can be respectively to dodging in groove of correspondence dodge, and closely block on the inwall of heat exchanger tube, this structure is very easy to use, such block mode is also very reliable, even if heat exchanger tube is given a shock or knocks in poling process, poling guide head can not be separated with heat exchanger tube yet, thus the auxiliary poling efficiency that has improved heat exchanger tube; In addition, this poling guide head can be applicable to the heat exchanger tube of multiple different tube diameters.
Accompanying drawing explanation
Fig. 1 is the structural representation of heat exchanger tube poling guide head of the present invention.
Fig. 2 is the structural representation that Fig. 1 overlooks direction.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail.
As Fig. 1, shown in Fig. 2, heat exchanger tube poling guide head, comprise conical nose 1, the rear end of conical nose 1 is provided with connecting rod 2, the bilateral symmetry of connecting rod 2 offers a pair of longitudinal setting, and the inside recessed groove 3 of dodging, this is respectively arranged with a spring leaf 4 to dodging in groove 3, each spring leaf 4 includes spring leaf body 41, the rear end of each spring leaf body 41 is provided with spring leaf afterbody 42, each spring leaf afterbody 42 is all fixedly mounted on correspondence and dodges on the installation base 5 of connecting rod 2 rear ends in groove 3, each spring leaf body 41 is all and protrudes from correspondence and dodge the circular-arc of groove 3, in the present embodiment, the front end of each spring leaf body 41 all stretches to corresponding dodging in groove 3, and leave and dodge gap with this bottom of dodging groove 3, during poling, a pair of spring leaf body 41 be subject to the extruding of heat exchanger tube inwall can be respectively to dodging of correspondence in groove 3, dodge and elasticity block on the inwall of heat exchanger tube.
Advantage of the present invention is: simple and practical, by the bilateral symmetry at connecting rod 2, spring leaf 4 is set and dodges groove 3, during poling, spring leaf body 41 is subject to the extruding of heat exchanger tube inwall and can to dodging in groove 3 of correspondence, dodges respectively, and tight block is on the inwall of heat exchanger tube, this structure is very easy to use, because spring leaf body 41 is larger with the contact area of heat exchanger tube inwall, therefore such block mode is also more reliable, even if heat exchanger tube is given a shock or knocks in poling process, poling guide head can not be separated with heat exchanger tube yet, thereby the auxiliary poling efficiency that has improved heat exchanger tube, in addition, this poling guide head can be applicable to the heat exchanger tube of multiple different tube diameters.
