Description
Technical field
Shell-and-tube heat exchanger tooling device technical field is the utility model is related to, specifically a kind of heat exchanger tube poling lock
Tight leader.
Background technology
Shell-and-tube heat exchanger is a kind of widely used heat transmission equipment, and it has high temperature high voltage resistant, simple in construction, cleaning side
Just, the advantages that strong adaptability.Shell-and-tube heat exchanger is made up of parts such as housing, heat exchanger tube, tube sheet, deflection plates.Heat exchanger tube is pipe
The core heat exchanger components of shell heat exchanger, its difficult point in shell-and-tube heat exchanger manufacturing process are poling processes.During poling according to
Lifting heat exchanger tube by operating personnel makes it sequentially pass through tube sheet, the pore on deflection plate.Conventional poling has two kinds of processes, and one
Kind method is the poling outside cylinder, and the method poling is easy, but is only applicable to heat exchange core body（Note：Heat exchange core body is by tube sheet, heat exchange
The parts such as pipe, deflection plate form）Average weight, and it is easier to pierce into the situation of cylinder.Another method is the poling in cylinder,
The method is applied to the larger heat exchange core body of weight, and the laggard cylinder of the larger heat exchange core body of weight poling outside cylinder is highly difficult,
Therefore can only in cylinder poling.It is that space is limited the shortcomings that poling in cylinder, it is not easy to operate, it is more difficult when heat exchanger tube is worn to enter
Solve.For being relatively large in diameter cylinder, start poling operative employee at initial stage can in cylinder skirt, but as heat exchanger tube progressively pierces into cylinder
Body, the space in cylinder can be gradually compressed, and when the inadequate people in the space in final cylinder stays, operating personnel must just come out.It is right
In the small cylinder of diameter, due to no operating space, operating personnel can only carry out poling outside body by intuition and experience, wear
Guan Shihui frequently encounters heat exchanger tube and wears the problem of not passing by with heat exchanger tube during pore decentraction, wastes time and energy.
Utility model content
The purpose of this utility model is to provide a kind of heat exchanger tube poling locking leader, is being exchanged heat with solving shell-and-tube heat exchanger

In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of heat exchanger tube poling locking leader, it includes lock sleeve, expander roll, the leader being mutually socketed；The lock sleeve is
Hollow stepped cylinder body, it includes lock sleeve afterbody and lock sleeve head, and the external diameter of lock sleeve afterbody is less than locking pullover
The external diameter in portion, the diameter of lock sleeve afterbody outer wall are less than the internal diameter of heat exchanger tube, and the external diameter on lock sleeve head is more than the outer of heat exchanger tube
Footpath；The side wall of lock sleeve afterbody is provided with several gaps, and its lumen caudal diameter is more than end diameter, its end diameter and locking
The internal diameter on set head is equal, and the side wall on lock sleeve head is provided with pin-and-hole；The expander roll is that shape is adapted with lock sleeve inner chamber
Afterbody be that round table-like, front end is columned solid, the front end side wall of expander roll is provided with the groove being adapted with pin-and-hole, expander roll
Front end length be more than lock sleeve head length；The leader profile is bullet-shaped, and its front portion is provided with towing pad, its afterbody
The blind hole being adapted provided with diameter with expander roll point diameter.
As further improvement of the utility model, the front end outer wall of the expander roll is provided with screw thread, on the inwall of blind hole
Provided with external screw thread is adapted on the outer wall of expander roll front end internal thread.
Further improved as of the present utility model, the front portion of the leader is provided with towing pad.
The utility model when in use, now penetrates expander roll from the lumen caudal of lock sleeve, and lock is extended in the front end of expander roll
Tight set, afterbody of the lock sleeve together with expander roll is stretched into heat exchanger tube, bonding jumper, bonding jumper are inserted in the pin-and-hole on lock sleeve head
Bottom be plugged in the groove of expander roll front end, then will at the top of leader alignment expander roll after screw in, gradually deeply draw with the top of expander roll
Inside the blind hole of head, the afterbody of expander roll gradually struts the bar seam of lock sleeve afterbody, lock sleeve afterbody is close in heat exchanger tube
On wall, the utility model is locked at the front end of heat exchanger tube.After the utility model assembles, bonding jumper is removed, is tied up in towing pad
Good pull rope, by pull rope from tubular heat exchanger tube sheet, deflection plate hole in sequentially pass through, traction of the heat exchanger tube in pull rope
Pore can be passed rapidly through under effect.
The beneficial effects of the utility model are：
（1）The leader that the utility model passes through the screw-in bullet-shaped at the top of the expander roll through locking head inner chamber so that lock
The afterbody bar seam of tight set gradually struts, and is close to the inwall of heat exchanger tube, the utility model is locked to the top of heat exchanger tube, passed through
The traction of pull rope carries out heat exchanger tube poling operation, time saving and energy saving, avoids the problem of heat exchanger tube is with pore decentraction；
（2）Self-locking structure of the present utility model, the blind hole for afterbody of taking the lead are connected with expander roll front threads, and leader can be securely
It is locked at heat exchanger tube top, simple in construction, install convenient, unfailing performance height；
（3）Leader is bullet-shaped in the utility model, and the concentricity requirement of exchange heat pipe and pore is not high, can effectively carry
High operating speed.
