Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings.
The present invention is further illustrated by the following examples, which are not intended to be limiting, but any modifications, equivalents, improvements, etc. within the scope of the present invention are intended to be included within the scope of the present invention.
Referring to fig. 1, 2 and 3, the invention provides a well joint tray, which comprises a tray bottom plate 1 and a well joint 2 arranged right above the tray bottom plate 1; the device also comprises a first coaming plate 3, a second coaming plate 4, an interlocking mechanism 5 and a cylinder 6; the first coaming 3 is fixed above the tray bottom plate 1; the second coaming 4 is hinged at one end of the first coaming 3 through a hinge 7; a limiting block 41 is arranged on one side, close to the ground well joint 2, of the second coaming 4, and the air cylinder 6 drives the second coaming 4 to rotate around the hinge 7 and is used for locking or releasing the ground well joint 2; the interlocking mechanism 5 is fixed on the first coaming 3 or the second coaming 4;
the interlocking mechanism 5 comprises a U-shaped bracket 51, an interlocking lever 52 and a sensor 54; the interlocking lever 52 is rotatably connected to the U-shaped bracket 51 through a pin 53; one end of the interlocking lever 52 is located in the first coaming 3, the other end is close to the sensor 54, and the force arm of one end of the interlocking lever 52 is larger than that of the other end.
When the tray opening signal is received during oiling operation, the piston rod of the air cylinder 6 is automatically retracted to drive the second coaming 4 to rotate around the hinge 7 for opening, so that the limiting block 41 releases the ground well joint 2, and the ground well joint 2 can smoothly slide out; after completion of the task, the well head 2 is slid onto the pallet base 1, and the well head 2 presses one end of the lever 52, the lever 52 rotates clockwise about the pin, the other end rotates toward the sensor 54, the sensor 54 detects a signal, and the interlock system recognizes that the well head 2 has been completely restoredBits. Length L of arm with lever 52 at side of well joint 2 1 Arm length L of lever 52 on sensor side 2 The length ratio of the support arms at two sides is n 1 ＝L 1 ：L 2 When the support arms on two sides rotate, the arc length ratio n 2 ＝L 1 ：L 2 . Since the arm of force at one end of the interlock lever 52 is greater than the arm of force at the other end, L1>L2, preferably, is n 2 Because the displacement of the ground well joint 2 in the tray is 12mm and the displacement of the sensing piece at one end of the sensor 54 is only 3mm, the influence of the position change of the ground well joint 2 on the distance between the end face of the sensor 54 and the sensing piece 521 is greatly reduced, and the interlocking reliability of the ground well joint tray is ensured.
When the oiling operation is finished, and the tray closing signal is received, the piston rod of the air cylinder 6 automatically pushes out to drive the second coaming 4 to rotate around the hinge 7 to close, the second coaming 4 and the first coaming 3 enclose the ground well joint 2, and when the second coaming 4 and the first coaming 3 enclose the ground well joint 2, the distance between the second coaming 4 and the other end of the first coaming 3 is smaller than the diameter of the ground well joint 2. The limiting block 41 arranged on the side edge of the second coaming 4 is just embedded into the groove on the side edge of the ground well connector 2, so that the ground well connector 2 is firmly locked in the tray, the problem that the ground well connector 2 jumps along with a vehicle is overcome, the displacement distance of the ground well connector 2 is reduced, and the stability of the interlocking mechanism is ensured.
Preferably, the interlocking lever 52 includes a sensing piece 521, a feeler lever 523, and a connecting shaft 522 for connecting the sensing piece 521 and the feeler lever 523, a through hole for accommodating the pin shaft 53 is provided on the connecting shaft 522, when the local well joint 2 leaves the tray 1, the sensor 54 collects the signal of the dislocation of the local well joint 2, so the sensing piece 521 must be far away from the end face of the sensor by a sufficient distance to ensure that the sensor 54 cannot detect the sensing piece 521 at this time, and a balancing weight 524 is provided below the sensing piece 521, so long as the gravity of the balancing weight 524 is large enough, the sensing piece 521 can be rotated counterclockwise by a sufficient distance, and the distance away from the end face of the sensor 54 exceeds 5 mm. Increasing the mass of the inductive pad 521 may be an alternative to providing a weight 524.
Preferably, the sensing piece 521 and the feeler lever 523 form an angle, and preferably, the degree of the angle is 90 degrees.
Preferably, the signal transmitted by the sensor 54 is a switching value, when the ground well joint is out of position, the sensor 54 outputs a signal 0, and when the ground well joint is reset, the sensor 54 outputs a signal 1.
Preferably, the interlocking mechanism 5 is provided with an arc-shaped baffle 55, and is sleeved outside the sensor 54. The arcuate shutter 55 is used to protect the sensor 54 from an operator striking the sensor 54 when retracting the well joint.
