Abstract
The invention relates to a center guiding device which comprises a base plate, and is characterized in that guiding mechanisms are installed on the left and the right on the base plate in a symmetrical manner, the guiding mechanism comprises a cylinder installation seat fixedly installed on the base plate, a cylinder is installed on the cylinder installation seat, and a piston rod of the cylinder is connected with a guide wheel rack provided with a guide wheel axle which is provided with an installation guide wheel. The guide wheel in the device rotates freely along with the transmission of a tube and is not blocked due to the bit bending of the tube so as to stop the tube from going forward. The cylinder on the center guiding device can avoid the head and tail of an oil tube with a thickened tube end or a drill pipe in running through a sensor, so that the tube is not collided in running; by adopting the center guiding device, a small specification oil tube is firstly located at the center in running, so that the oil tube can be used even if being abraded into a U type large idler wheel pinch roll, and signals are not interfered due to severe swaying caused by uneven magnetic field strength for the running small tube is not in the center.
Description
Technical field
The present invention relates to a kind of guide piece, especially a kind of centre pilot device that uses when entering the magnetic leakage detection checkout equipment in the steel pipe testing process.
Background technology
In the magnetic leakage detection testing process, need the steel pipe of detection, translate into the V-type transfer roller by feeding skid by propping up, enter the magnetic leakage detection checkout equipment.Owing to using for a long time operation, the V-type roller-way that transmits all weares and teares into U-shaped with the V-type nip rolls on Magnetic Flux Leakage Inspecting equipment, operating steel pipe head enters the vertical rotary body of leakage field, and (this rotary body is 0 ° and the 180 ° magnetization cushion block that the adjustable magnetization current of two symmetries is arranged, and magnetic is stronger; During work, the rotary body rotating speed is 170 ~ 200 rev/mins) time usually not at the center, the pipe sizing that adds detection is φ 60.3*4.4 ~ φ 88.9*6.45mm, pipe is thin, soft, when pipe not two the magnetization cushion blocks the center time, powerful and magnetic field at a high speed causes 1.5 meters double swerve severities of head, afterbody of steel pipe, head, tail signal is unstable, causes this section pipe normally to detect.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of centre pilot device is provided, this device can guarantee that operating pipe head transmits, and realizes centralized positioning on center line.
According to technical scheme provided by the invention, described centre pilot device, comprise base plate, it is characterized in that: on described base plate, left-right symmetric is installed guiding mechanism, described guiding mechanism comprises the cylinder mount pad that is fixedly mounted on base plate, on the cylinder mount pad, cylinder is installed, and the piston rod of cylinder is connected with the guiding wheel carrier, the guiding wheel carrier is provided with guide wheel shaft, and angle sheave is installed on guide wheel shaft.
Described guide wheel shaft is vertical with base plate to be arranged.
On described cylinder mount pad, orienting sleeve is set, the cylinder guidance bar is set in orienting sleeve, an end of cylinder guidance bar is fixed with the guiding wheel carrier, and the guiding wheel carrier makes guide wheel shaft and base plate keep plumbness under the effect of cylinder guidance bar.
The present invention has the following advantages: (1) centre pilot device of the present invention can make operating pipe head move at center line on request; (2) angle sheave of the present invention freely rotates with the transmission of pipe, can not suppress because pipe is somewhat curved stuckly, causes pipe to advance; (3) cylinder on centre pilot device of the present invention can be dodged be in operation head and afterbody of the oil pipe of end upsetting and drilling rod by sensor, pipe is in operation is not collided; (4) after employing device of the present invention, to the oil pipe first centre of location when moving than small dimension, be worn down to so U-shaped larger roller nip rolls and also can move use, can be because of the tubule of operation not at the center, magnetic field intensity is inhomogeneous and rock severe undesired signal; Do not need to change wearing and tearing into U-shaped roller nip rolls at once, saved cost at once; (5) use device of the present invention after, the phenomenon at the center can not appear grinding partially not in the V-type nip rolls on device Host.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the structural representation of guiding mechanism of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As Fig. 1 ~ shown in Figure 3: as described in the centre pilot device comprise base plate 1, orienting sleeve 2, cylinder mount pad 3, cylinder 4, guiding wheel carrier 5, guide wheel shaft 6, angle sheave 7, cylinder guidance bar 8 etc.
As shown in Figure 1, the present invention includes base plate 1, on base plate 1, left-right symmetric is installed guiding mechanism, described guiding mechanism comprises the cylinder mount pad 3 that is fixedly mounted on base plate 1, cylinder 4 is installed on cylinder mount pad 3, and the piston rod of cylinder 4 is connected with guiding wheel carrier 5, and guiding wheel carrier 5 is provided with guide wheel shaft 6, angle sheave 7 is installed in guide wheel shaft 6 setting vertical with base plate 1 on guide wheel shaft 6;
As shown in Figure 1, on described cylinder mount pad 3, orienting sleeve 2 is set, cylinder guidance bar 8 is set in orienting sleeve 2, an end of cylinder guidance bar 8 is fixing with guiding wheel carrier 5, guiding wheel carrier 5 makes its guide wheel shaft 6 and base plate 1 keep plumbness under the effect of cylinder guidance bar 8.
Principle of work of the present invention and the course of work: as shown in Figure 1, before described centre pilot device is arranged on Magnetic Flux Leakage Inspecting equipment, the sensor of an adjustable delay time is installed before this device, is controlled the action of two cylinders; Before operating pipe 9 heads also do not enter this device, (regulate time expand as required) when encountering sensor, the piston rod of the cylinder 4 of left and right sides guiding mechanism is action forward respectively, the angle sheave 7 of both sides is just in time encountered pipe and (is not wanted clamping tube, pipe can not be advanced), make it be positioned at the roller-way center and advance; When pipe 9 afterbody separating sensor, the piston rod of both sides cylinder 4 shrinks simultaneously; When a bit bending of pipe 9, when encountering angle sheave 7, angle sheave 7 meeting automatic rotations are avoided pipe to block and can't be advanced.
