Abstract
The invention provides a through tube guiding head and relates to a petroleum through tube guiding device. A tube bundle penetrating-leading connector comprises a mandrel, one end of the mandrel is fixedly provided with a tensioning ring, a U-shaped centering cone is fixedly arranged outside the mandrel, the other end of the mandrel is provided with a guiding cone, and the guiding cone extends to the outside of the centering cone to be elastically connected with the centering cone. The tube bundle penetrating-leading connector can be accurately aligned at a heat exchange tube center and a guiding head center, guiding of specially-assigned persons is not required in the tube penetrating process, the guiding cone and the centering cone of the tube bundle penetrating-leading connector are connected elastically, slipping caused by inertance of the through tube guiding head can be effectively prevented, and the through tube guiding head can remarkably improve the work efficiency and is strong in practical applicability.
Description
Technical field
The present invention 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 present invention is intended to propose a kind of tube bank biography and draws joint.
Tube bank of the present invention 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 guide cone, and described guide cone extends to the centering cone outside, and elasticity connects with it.
Preferably, interconnect by spring between guide cone and the centering cone.。
Preferably, described axle is connected with the tightening hoop wedge shape.
Tube bank of the present invention connects joint can accurately aim at heat exchanger tube center and seeker center, the poling process need not special messenger's guiding, tube bank passes between the guide cone draw joint and the centering cone adopts elasticity to connect, can prevent effectively that leading head for through pipe is because of the inertia slippage, the present invention can significantly improve operating efficiency, and is practical.
Description of drawings
Fig. 1 is structural representation of the present invention.
1-axle among the figure; 2-U type centering cone; The 3-guide cone.
The specific embodiment
Tube bank of the present invention 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 guide cone 3, interconnects by spring between described guide cone 3 and the U-shaped centering cone 2, and axle 1 of the present invention is connected with the tightening hoop wedge shape.
Tube bank of the present invention connects joint, behind leading head for through pipe 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 with leading head for through pipe balance of shaking force forward, thereby prevent the seeker slippage.U-shaped centering cone 2 can make the center of leading head for through pipe consistent with the heat exchanger tube center, and anterior guide cone 3 can guide the pore that enters each deflection plate and tube sheet automatically with heat exchanger tube in the poling process, to pipe end seeker is pulled up and can be reused after being finished.
Claims (3)
