Wherein, the support wall 1 has two, and the wall of two support walls 1 is perpendicular to the horizontal plane and mutually faces, has played strutting arrangement's effect.
The extrusion assembly 2 comprises a pressing plate 21, main struts 22, secondary struts 23 and a plurality of racks 25, the pressing plate 21 has two, the surfaces of the two pressing plates 21 are parallel to the horizontal plane and face each other, the two pressing plates 21 are located between the two supporting walls 1 and are far away from each other, the main struts 22 and the secondary struts 23 have four groups, two groups of main struts 22 and secondary struts 23 are fixedly connected to the front side and the rear side of the top end surface of the pressing plate 21 above, the other two groups of main struts 22 and secondary struts 23 are fixedly connected to the front side and the rear side of the bottom end surface of the pressing plate 21 below, the side walls of the main struts 22 and the secondary struts 23 are both fixedly and vertically provided with one rack 25, the direction of the notches of the racks 25 on the same pressing plate 21 is the same, and the.
The number of the main gears 3 is four, every two main gears 3 are horizontally and fixedly arranged on the inner wall of the supporting wall 1 and positioned at the left end and the right end of the wall surface, and the two corresponding main gears 3 on the two supporting walls 1 are fixedly connected in a shaft mode.
Eight transmission gears 4 are provided, every two transmission gears 4 are vertically and fixedly arranged on the inner wall of the supporting wall 1, each group of transmission gears 4 is meshed with one main gear 3, the transmission gears 4 are located between the two main gears 3, and the two transmission gears 4 are meshed with one main gear 3 up and down and the transmission gears 4 are arranged between the two main gears 3, so that the rotation directions of the four transmission gears 4 on the same side are opposite in sequence.
The driving gears 5 are fixedly connected to the rotating shaft of the transmission gear 4 and are positioned on the inner side of the supporting wall 1, and each driving gear 5 is meshed with a rack 25 to drive the main supporting column 22 and the secondary supporting column 23 to move up and down.
The belt pulley 6 is fixedly connected with a rotating shaft of the main gear 3 and is positioned outside the supporting wall 1, and the two belt pulleys 6 on the same side are driven by a belt to simultaneously drive the four main gears 3 to rotate in the same direction.
An output shaft of the motor 7 is fixedly connected with one of the belt pulleys 6 to provide driving force.
By adopting the technical scheme, the oil pipe is placed on the pressing plate 21 below the oil pipe, and the two ends of the oil pipe are communicated with the oil transportation system; starting a motor 7 to drive the fixedly connected belt pulley 6 and the main gear 3 to rotate, so that the four main gears 3 rotate in the same direction; because each group of two transmission gears 4 is vertically meshed with one main gear 3, the rotation directions of the four transmission gears 4 on the same side are opposite in sequence, and the rotation direction of the driving gear 5 is the same as that of the transmission gear 4 fixedly connected with the driving gear; and then the two pressing plates 21 are driven to move oppositely or back to back in the direction vertical to the horizontal plane, so as to extrude or loosen the oil pipe body placed on the pressing plate 21 below. In the process, the extrusion force applied to the oil pipe body comes from the surface of the pressing plate 21, and the extrusion force is always kept in the direction vertical to the horizontal plane, so that the stress is more uniform and the stress direction is consistent.
Specifically, the invention is also realized by the following technical scheme.
In order to ensure uniform downward or upward extrusion force of the pressing plate 21, the racks 25 of the main strut 22 and the secondary strut 23 are respectively positioned at two ends of the side edge of the end surface of the same pressing plate 21, so that the stress positions of the driving gear 5 which is meshed with the racks 25 and drives the main strut 22 and the secondary strut 23 to move up and down are positioned at two ends of the side edge of the end surface of the pressing plate 21 but not in the middle of the side edge of the end surface of the pressing plate 21, the problem that one end of the pressing plate 21 is tilted due to non-uniform stress is avoided, and uniform and consistent extrusion force.
As some optional embodiments, the main support column 22 and the secondary support column 23 on the same press plate 21 are fixedly connected with each other, so that the function similar to a reinforcing rib is achieved, the whole structure of the press plate 21 is more stable, risks such as deformation of the plate surface of the press plate 21 or stress fracture of the main support column 22 and the secondary support column 23 are avoided, and the accuracy of the test is improved to a certain extent.
The working principle is as follows:
firstly, the oil pipe is placed on the lower pressure plate 21, and two ends of the oil pipe are communicated with an oil transportation system. It should be noted that, during the test, a plurality of oil pipes are generally set at the same time, the oil pipes can be placed on the pressing plate 21 in parallel, and the pressing plate 21 only needs to extrude the pipe body of the oil pipe, so the length of the oil pipe can be greater than the length of the pressing plate 21, the two ends of the oil pipe extend out of the pressing plate 21, and at this time, after the joint of the joint end of the oil pipe is connected, the test is not influenced without fixing. Of course, fixing devices may be provided at both ends of the pressure plate 21 to fix the joint end of the oil pipe.
Then, the motor 7 is started to drive the fixedly connected belt pulley 6 and the main gear 3 to rotate, and because the two belt pulleys 6 on the same side are transmitted by the belt and the two corresponding main gears 3 on the two supporting walls 1 are fixedly connected by the shaft, the four main gears 3 can rotate in the same direction.
Because each group of two transmission gears 4 are vertically meshed with one main gear 3, and the transmission gears 4 are arranged between the two main gears 3, the rotation directions of the four transmission gears 4 on the same side are opposite in sequence, and the rotation direction of the driving gear 5 is the same as the rotation direction of the transmission gear 4 fixedly connected with the driving gear.
Therefore, under the driving of the gear transmission mechanism, the two pressing plates 21 can move oppositely or oppositely in the direction perpendicular to the horizontal plane, so as to extrude or loosen the oil pipe body placed on the pressing plate 21 below. In the process, the extrusion force applied to the oil pipe body comes from the surface of the pressing plate 21, and the extrusion force is always kept in the direction vertical to the horizontal plane, so that the stress is more uniform and the stress direction is consistent.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
