Abstract
The utility model belongs to the technical field of pipeline construction of petrifaction, power, coal and water delivery and the like and provides a hinged seat pair mechanism of a pneumatic inner aligner of a pipeline. The hinged seat pair mechanism is of a ring-shaped structure which is formed by a plurality of hinged seats (1) uniformly distributed along the periphery; the plurality of hinged seats (1) are uniformly distributed on the end surface of a piston rod along the periphery, and are V-shaped; the center of each hinged seat (1) is provided with a through groove (7) into which a connecting rod can be inserted; each hinged seat (1) is provided with pin shaft holes (8), and the connecting rod and the hinged seats are connected into a whole by virtue of pin shafts; and each hinged seat (1) is provided with bolt holes (9), and the hinged seats are fixed on the end surface of the piston rod by virtue of bolts. The hinged seat pair mechanism has the advantages that the force transmission smoothness and the force bearing reliability are achieved in a four-link mechanism, the phenomena that an expanding shoe at the head of the mechanism can not expand, or generates creep, can not expand fully, and even is clamped; and simultaneously, the purposes of convenience in installation, stability and reliability are achieved.
Description
Technical field
The utility model belongs to pipeline construction technology fields such as petrochemical industry, electric power, coal, water delivery, relates generally to a kind of secondary mechanism of hinged seat of conduit pipe pneumatically internal clamp.
Background technology
The conduit pipe pneumatically internal clamp is a requisite corollary equipment in the long-distance transmission pipeline job site, also is the first element equipment in this construction, and it mainly helps two pipeline butt joints, and guarantees that two pipeline unfitnesses of butt joint are in certain specification requirement scope; Its groundwork principle is: like Fig. 1, shown in Figure 2; Whether be not appreciated that to head, back head before corresponding have one and overlap propulsion cylinder A and the quadric chain B that acts on two mouth of pipe inwalls; Realize the counterpart operation; Forward and backward handpiece structure principle is the same all to be through a cover quadric chain the horizontal propulsive force of cylinder to be changed direction, finally acts on the steel pipe inwall perpendicular to the horizontal propulsive force of cylinder; And the horizontal propulsive force of cylinder is decomposed into a plurality of vertical forces of dividing equally through a cover quadric chain B; Quadric chain also has a critical function simultaneously: reinforcing----increases tan85 ° doubly through quadric chain with the horizontal propulsive force of cylinder; This cover quadric chain is formed by many groups quadric chain is secondary, and every group of quadric chain pair is made up of bearing pin 4 four parts that hinged seat 1, connecting rod 2, push rod 3 and three link to each other again; And playing the effect of power transmission and load as the secondary critical component hinged seat of quadric chain, its quality affects the ride comfort of dividing equally property of cylinder thrust, power transmission and the reliability of load.
About pneumatic secondary to the hinged seat in the mouthpart head; Overview is both at home and abroad: the hinged seat pair of this serial equipment all adopts integral type both at home and abroad at present; Be hinged seat and propulsion cylinder piston rod one, the half slot of the installation bearing pin of dividing equally in piston rod end face processing, and then process an end cap and compress the bearing pin that hinged seat links to each other with connecting rod; Each group quadric chain pair is independent all; Their acting in conjunction is on the propulsion cylinder piston rod, and piston rod movement drives the secondary action of a cover quadric chain of dividing equally simultaneously when the cylinder work done, and power is changed into perpendicular to level and a plurality of component that act on inner-walls of duct of dispersing to circumference by level.But these hinged seat parts are owing to adopt integral type, the dividing equally property of half slot of dress bearing pin, the disposition work in-process is difficult to guarantee, from the processing technology aspect because big with piston rod one difficulty of processing; Compress so adorn the bearing pin hinged seat in addition and be the end cap that fixedly needs of half slot bearing pin, end cap is loosening easily in the quadric chain secondary motion; Phenomenons such as these finally influences the ride comfort of the secondary power transmission of quadric chain and reliabilities of load, and the boots that rise that head can occur can not rise or occur wriggling, and rising is unable even stuck have directly influenced life-span of equipment.
The utility model content
The purpose of the utility model is the secondary mechanism of hinged seat that proposes a kind of conduit pipe pneumatically internal clamp; Make it in quadric chain, play the reliability of the ride comfort and the load of power transmission; The boots that rise of avoiding occurring head can not rise or wriggling, the unable even stuck phenomenon of rising occur; Reach purpose easy for installation, reliable and stable simultaneously.
The utility model adopts following technical proposals to accomplish its invention task:
The secondary mechanism of a kind of hinged seat of conduit pipe pneumatically internal clamp, the secondary mechanism of the hinged seat cirque structure that several hinged seats that are uniformly distributed along the circumference constitute of serving as reasons, and the internal radius of the secondary mechanism of said hinged seat is identical with the external diameter of piston rod; Described several hinged seats along circle distribution on the end face of piston rod; Described hinged seat is a V-type, has at the center of said hinged seat in order to insert the groove of connecting rod; On described hinged seat, have pin shaft hole, connecting rod and hinged seat are articulated as one by bearing pin; Described pin shaft hole is perpendicular to the both sides groove face of groove, and runs through the both sides groove face of groove; On described hinged seat, have bolt hole, hinged seat is fixed on the end face of piston rod by bolt.
The secondary mechanism of the hinged seat of a kind of conduit pipe pneumatically internal clamp that the utility model proposes; The design of employing said structure; Make the secondary mechanism of hinged seat in quadric chain, play the reliability of the ride comfort and the load of power transmission; The boots that rise of avoiding occurring head can not rise or wriggling, the unable even stuck phenomenon of rising occur; Reached purpose easy for installation, reliable and stable simultaneously.
