Description
Technical field
A kind of heat exchanger tube poling guide head is the utility model is related to, more particularly to a kind of removable heat exchanger tube is led with poling
To 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 assembles tolerance with existing after deflection plate assembling, so heat exchanger tube is actually being worn
If can not pass through among process, generally just need to assist 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 gap between connecting rod and heat exchanger tube be present, 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, the purpose of this utility model, which is to provide one kind, can effectively prevent from coming off, and and can is applied to more
The removable heat exchanger tube poling guide head of kind specification heat exchanger tube.
To achieve the above object, technology contents of the present utility model are a kind of removable heat exchanger tube poling guide head, bag
The connecting rod of conical head and cylinder is included, the rear end of conical head is provided with internal thread hole；The front end of connecting rod be provided with external thread column with
Internal thread hole on conical head is threadedly coupled to form an entirety.Set respectively on the face of cylinder close to connecting rod front-end and back-end
There are four escape groove being circumferentially uniformly and symmetrically distributed, the centerline axis parallel setting of escape groove and connecting rod, escape groove groove
The rear end at bottom 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, spring leaf
Front end is in arc-shaped and protrudes from escape groove.
The utility model is respectively provided with spring leaf in the front-end and back-end of connecting rod, connecting rod is stuck in securely and changes
In heat pipe；And a kind of connecting rod of specification can internal diameter the extreme higher position that connection shank diameter and spring leaf are upspring diameter it
Between different size heat exchanger tube between realize it is general.During heat exchanger tube is worn, the heat exchanger tube of different size is just selected
The conical head of dimension, the connecting rod for being connected through a screw thread and being applicable link up, and this dismountable structure makes conical head and company
What extension bar can neatly be applied in combination to meet the heat exchanger tube of plurality of specifications wears work.
Compared with prior art, the utility model advantageously can effectively prevent from coming off, and and can is applied to more
The heat exchanger tube of kind specification.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is in Fig. 12 right view.
Embodiment
The utility model 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, including 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, spring leaf 4 is provided with fixed station 5, 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.
