Abstract
The utility model provides a pipe-penetrating guide head and relates to a petroleum pipe-penetrating guide device. The pipe-penetrating guide head comprises a spindle. One end of the spindle is fixedly provided with a tensioning ring. A U-shaped centering cone is fixedly arranged outside the spindle. The other end of the spindle is provided with a guide cone. The guide cone stretches to the outside of the centering cone and is connected with the centering cone in an elastic mode. According to the pipe-penetrating guide head, the center of the guide head can be accurately aimed at the center of a heat exchanging pipe. Guiding by a specially-assigned person is not needed in a pipe-penetrating process. The guide cone of a pipe bundle guide connector is in elastic connection with the centering cone, so that the pipe-penetrating guide head is effectively prevented from slipping off because of inertia. The pipe-penetrating guide head can improve working efficiency remarkably and is strong in practicality.
Description
Technical field
The utility model relates to a kind of oil poling guiding device.
Background technology
In petrochemical industry is produced, heat exchanger tube often because of the heat exchanger tube corrosion failure, block too much and scrap, cause the higher wasting of resources, in order to save investment, some petrochemical plants are from the old tube sheet of the intrafascicular recovery of the Tube Sheet of Heat Exchanger of scrapping and part deflection plate, after trimming, penetrate new pipe and make new tube bank, re-use.
Summary of the invention
The utility model is intended to propose a kind of poling seeker.
Tube bank described in the utility model connects joint, comprises axle, and an end of axle is fixed with tightening hoop, and the external stability of axle is provided with U-shaped centering cone, and the other end of axle is provided with the guiding awl, and described guiding awl extends to the centering cone outside, and elasticity connects with it.
Preferably, interconnect by spring between guiding awl and the centering cone.
Preferably, described axle is connected with the tightening hoop wedge shape.
Tube bank described in the utility model connects joint can accurately aim at heat exchanger tube center and seeker center, the poling process need not special messenger's guiding, adopt elasticity to connect between the guiding awl of poling seeker and the centering cone, can prevent effectively that the poling seeker is because of the inertia slippage, the utility model can significantly improve operating efficiency, and is practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-axle among the figure; 2-U type centering cone; The 3-awl that leads.
The specific embodiment
Tube bank described in the utility model connects joint and comprises axle 1, the external stability of axle 1 is provided with U-shaped centering cone 2, the outside of U-shaped centering cone 2 is provided with guiding awl 3, interconnect by spring between described guiding awl 3 and the U-shaped centering cone 2, axle 1 described in the utility model is connected with the tightening hoop wedge shape.
Tube bank described in the utility model connects joint, behind poling seeker afterbody insertion heat exchanger tube end, the elastic force of spring itself makes the inclined-plane extruding tightening hoop of axle 1 afterbody, the heat exchanging inside pipe wall produces radial pressure, when pause or impact are arranged in the poling process, the frictional force that produces between tightening hoop and the heat exchanger tube inwall can guide headlong balance of shaking force with poling, thereby prevents the seeker slippage.U-shaped centering cone 2 can make the center of poling seeker consistent with the heat exchanger tube center, and anterior guiding awl 3 can guide the pore that enters each deflection plate and tube sheet automatically with heat exchanger tube in the poling process, use up the back and to pipe end seeker is pulled up and can be reused.
