Abstract
The invention discloses a guide head used for preventing disconnection of heat exchange tube during a tube penetrating process. The guide head comprises a conical head part, a connecting bar is arranged at the rear end of the conical head part and provided with a connecting trough horizontally, an adjusting bolt, a spring and a steel ball are sequentially arranged in the connecting trough, the adjusting bolt is matched and connected with the inner wall of the connecting trough by threads, the diameter of the port of the other end of the connecting trough is smaller than that of the steel ball so that a part of the steel ball can protrude the connecting bar but can not fall out of the connecting trough. The guide head has the advantages that the structure is simple, the steel ball and the inner wall of the heat exchange tube can be clamped as the elastic force of the spring acts on the steel ball, the situation that the heat exchange tube is disconnected from the connecting bar due to vibration or knocking during the tube penetrating process can be effectively avoided, and the working efficiency is greatly improved.
Description
Technical field
The present invention relates to heat exchanger poling guider, be specifically related to heat exchanger tube anticreep poling guide head.
Background technology
When making heat exchanger; Heat exchanger tube need be located on tube sheet and the deflection plate; Owing to be drilled with pore on tube sheet and the deflection plate; The caliber gap of the aperture of pore and heat exchanger tube is less; And there is assembling tolerance after tube sheet and the deflection plate assembling,, usually the poling guide head need be set in the end of heat exchanger tube so heat exchanger tube is difficult to pass pore when actual wearing; The structure of traditional poling guide head comprises: conical nose, the rear end of conical nose is provided with connecting rod.When wearing, heat exchanger tube directly is sleeved on the connecting rod matched in clearance between connecting rod and the heat exchanger tube.Owing to wear in the process, heat exchanger tube can be vibrated and knocked, and comes off easily between heat exchanger tube and the poling guide head like this, falls into after causing the poling guide head to come off to be difficult to taking-up in the equipment.
Summary of the invention
The problem that the present invention need solve provide a kind of heat exchanger tube anticreep poling guide head that can prevent effectively that heat exchanger tube and poling guide head come off in the process of wearing.
For addressing the above problem; The technical scheme that the present invention adopts is: heat exchanger tube anticreep poling guide head; Comprise: conical nose; The rear end of conical nose is provided with connecting rod; Be horizontally arranged with link slot on the connecting rod, be disposed with in the link slot and regulate bolt, spring, steel ball, regulate bolt and be connected through screw thread and link slot inwall; The diameter of link slot other end port is less than the diameter of steel ball, makes steel ball have part can protrude connecting rod but can not drop out link slot.
Advantage of the present invention is: simple in structure; The elastic force of spring acts on the steel ball; Thereby steel ball and heat exchanger tube inwall tightened each other, effectively avoided heat exchanger tube in the poling process because vibration or knock and take place with situation that connecting rod comes off has improved operating efficiency greatly.
Description of drawings
Fig. 1 is the structural representation of heat exchanger tube anticreep poling guide head of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
As shown in Figure 1; Heat exchanger tube anticreep poling guide head; Comprise: conical nose 1; The rear end of conical nose 1 is provided with connecting rod 2; Connecting rod 2 is provided with link slot 3, is disposed with in the link slot 3 to regulate bolt 4, spring 5, steel ball 6, regulates bolt 4 and is connected through screw thread and link slot 3 inwalls; The diameter of link slot 3 other end ports is less than the diameter of steel ball 6, makes steel ball 6 have part can protrude connecting rod 2 but can not drop out link slot 3.
During poling; The heat exchanger tube that caliber is adapted is sleeved on the connecting rod 2; Tightening adjusting bolt 4 makes spring 5 be in the compression state; The elastic force of spring 5 acts on the steel ball 6; Thereby steel ball 6 and heat exchanger tube inwall are tightened each other; Connecting rod 2 is connected closelyr with the heat exchanger tube inwall like this, and heat exchanger tube just can not come off because of in the poling process, being vibrated and knocking with connecting rod 2.That end port of steel ball 6 protrusions is as long as guarantee that steel ball 6 can protrude connecting rod 2 and can not drop out link slot 3 again.
Advantage of the present invention is: simple in structure, effectively avoided heat exchanger tube in the poling process because vibration or knock and take place with situation that connecting rod comes off has improved operating efficiency greatly.
