Abstract
The present invention relates to a kind of removable heat exchanger tube poling guide head, include the connecting rod of conical head and cylinder, it is characterised in that the rear end of conical head is provided with internal thread hole；The front end of connecting rod is threadedly coupled provided with external thread column with the internal thread hole on conical head, four escape groove being circumferentially uniformly and symmetrically distributed are being respectively equipped with the face of cylinder of connecting rod front-end and back-end, the centerline axis parallel of escape groove and connecting rod is set, the rear end of escape groove bottom land is provided with fixed station, spring leaf is provided with fixed station, the rear end of spring leaf is fixedly connected with fixed station, and the front end of spring leaf is in arc-shaped and protrudes from escape groove.The present invention has the advantages that effectively prevent from coming off and can be suitably used for plurality of specifications heat exchanger tube.
Description
Technical field
It is oriented to the present invention relates to a kind of heat exchanger tube poling guide head, more particularly to a kind of removable heat exchanger tube with poling
Head.
Background technology
A kind of heat exchange equipment is mainly made up of parts such as housing, heat exchanger tube, tube sheet, deflection plates, is manufacturing this heat exchange
, it is necessary to which heat exchanger tube is located on tube sheet and deflection plate during device, pore is drilled with tube sheet and deflection plate, due to pore with
Fit-up gap between heat exchanger tube is smaller, and tube sheet after deflection plate assembling with having assembling tolerance, so heat exchanger tube is actually being worn
If can not pass through among process, generally it is accomplished by assisting heat exchanger tube to pass through using poling guide head in one end of heat exchanger tube
Pore on tube sheet and deflection plate.The structure of traditional poling guide head includes conical head and the connecting rod being attached thereto.Wear
When, according to the specification of various heat exchange pipe, selection corresponds the poling guide head of size, by the connection bar portion of poling guide head
Divide insertion heat exchanger tube, gap coordinates between connecting rod and heat exchanger tube.Due to there is gap between connecting rod and heat exchanger tube, so even
Extension bar is to loosen in heat exchanger tube, and heat exchanger tube can be given a shock and tap during wearing so that connecting rod is easy to
Taken off from heat exchanger tube by shake, cause poling guide head to be fallen into after coming off in installation equipment and be difficult to take out, and a kind of specification
Poling guide head may be only available for a kind of heat exchanger tube of specification.
The content of the invention
For disadvantages mentioned above, it can effectively prevent from coming off it is an object of the invention to provide one kind, a variety of rule are can be suitably used for again
The removable heat exchanger tube poling guide head of lattice heat exchanger tube.
To achieve the above object, technology contents of the invention are, a kind of removable heat exchanger tube poling guide head, including cone
The connecting rod of forming head and cylinder, the rear end of conical head is provided with internal thread hole；The front end of connecting rod is provided with external thread column and taper
Internal thread hole on head is threadedly coupled to form an entirety.Four are being respectively equipped with the face of cylinder of connecting rod front-end and back-end
The centerline axis parallel of the individual escape groove being circumferentially uniformly and symmetrically distributed, escape groove and connecting rod is set, escape groove bottom land
Rear end is provided with fixed station, and spring leaf is provided with fixed station, and the rear end of spring leaf is fixedly connected with fixed station, the front end of spring leaf
In arc-shaped and protrude from escape groove.
The present invention is respectively provided with spring leaf in the front-end and back-end of connecting rod, connecting rod is stuck in heat exchanger tube securely
In；And a kind of connecting rod of specification can be between diameter of the internal diameter in the extreme higher position that connection shank diameter and spring leaf are upspring
Realized between the heat exchanger tube of different size general.During heat exchanger tube is worn, the heat exchanger tube of different size is just from corresponding
The conical head of specification, the connecting rod for being connected through a screw thread and being applicable is linked up, and this dismountable structure makes conical head and connecting rod
The heat exchanger tube that can neatly be applied in combination to meet plurality of specifications wears work.
Compared with prior art, advantage for present invention is can effectively to prevent from coming off, and a variety of rule are can be suitably used for again
The heat exchanger tube of lattice.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is in Fig. 12 right view.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1 Fig. 2, a kind of removable heat exchanger tube poling guide head includes the connecting rod of conical head 1 and cylinder
2, the rear end of conical head 1 is provided with internal thread hole 1.1；The front end of connecting rod 2 is provided with external thread column 2.1 and the interior spiral shell on conical head 1
Pit 1.1 threaded connection formed an entirety, close to the front-end and back-end of connecting rod 2 the face of cylinder on be respectively equipped with four along
The symmetrical escape groove 3 of even circumferential, the centerline axis parallel of escape groove 3 and connecting rod 2 is set, after the bottom land of escape groove 3
End is provided with fixed station 5, and spring leaf 4 is provided with fixed station 5, and the rear end of spring leaf 4 is fixedly connected with fixed station 5 with bolt, bullet
The front end of reed 4 is in arc-shaped and protrudes from escape groove 3.
