Abstract
The invention discloses a convenient and fast pipe construction welding opening correcting device which comprises a first circle correcting frame of a semicircular structure and a second circle correcting frame of a semicircular structure. One end of the first circle correcting frame is hinged to one end of the second circle correcting frame through a first hinge pin, and an ejecting mechanism is arranged at the other end of the first circle correcting frame and the other end of the second circle correcting frame. The convenient and fast pipe construction welding opening correcting device is simple in structure, easy to operate, convenient to use, firm in fixation and capable of being widely applied to correcting and fixing the two part pipe ends when pipes are in butt joint in the construction site, time and labor are saved, and the pipe laying quality is greatly improved.
Description
Technical field
The invention belongs to a kind of pipeline construction technology field, relate in particular to a kind of portable pipeline construction welding school mouthpart.
Background technology
Due to pipeline and pipe fitting product in process of production, the ovality of end face requires to have certain margin of tolerance according to GB, product is in long-distance transportation process on the other hand, there will be and push the phenomenon of jolting, thereby cause at the construction field (site) two pipelines or pipe fitting product in welding process, to occur the phenomenon of displacement, mismatch and port deformation misalignment, thereby affect welding and the laying work of integrated piping.And at the construction field (site), owing to lacking effective tool, and because conduit volume is huge, weight is very heavy, in the time there is port misalignment, can only rely on the artificial correction of beaing, easily there is accident, on the other hand inefficiency in the mode of this counterpart on the one hand, waste time and energy, affected the laying quality of pipeline.
Summary of the invention
The present invention, in order to solve weak point of the prior art, provides a kind of portable pipeline construction easy and simple to handle, that counterpart efficiency is high, time saving and energy saving to weld school mouthpart.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of portable pipeline construction welding school mouthpart, comprise the first school circle frame and the second school circle frame of equal semicircular in shape structure, one end of the first school circle frame and the second school circle frame is hinged by the first bearing pin, and the other end of the first school circle frame and the second school circle frame is provided with jacking mechanism.
Described jacking mechanism comprises jack, the first gripper shoe, the second gripper shoe and two connecting plates, the first gripper shoe is located at the end of the first school circle frame, one end of two connecting plates is hinged by the second bearing pin and the second school circle frame, the second gripper shoe is located between the other end of two connecting plates, the first gripper shoe and the second gripper shoe be arranged in parallel, jack be placed in the first gripper shoe and with the second gripper shoe top interference fit.
Described the first school circle frame is identical with the second school circle shelf structure, and the first school circle frame and the second school circle frame include two semicircular plates, between two semicircular plates, are provided with and are evenly provided with at least two stiffeners.
Adopt technique scheme, the present invention utilizes a small-sized hydraulic jack, make the first school circle frame and the second school circle frame form a circle completing, two semicircular plates of the first school circle frame and the second school circle frame lay respectively at the pipe end of two needs welding, push up simultaneously and press the first gripper shoe and the second gripper shoe by the active force of hydraulic jack, the second gripper shoe drives the second school circle frame by two connecting plates, the first gripper shoe drives the first school circle frame, the stressed opposite direction of the movable end of the first school circle frame and the second school circle frame, so just can make the first school circle frame and the second school circle frame clamp the port of two pipelines simultaneously, make two pipe ends reach concentric, and make the end face of two pipelines justify alignment in school simultaneously, thereby solve the problem of manually beaing correction that relies on, greatly improve operating efficiency, manpower and materials are saved, also be convenient to follow-up pipeline welding work simultaneously.
Adopt two connecting plates and the second school circle frame hinged, can guarantee that like this jack is pressed on top time, guarantee that the first gripper shoe and the second gripper shoe remain parastate, reduce the stress self producing in clamping process.
The present invention is simple in structure, easy operating, easy to use, time saving and energy saving, fixed, the laying quality that greatly improves pipeline, the correction of two parts pipe ends and fixing can be widely used in pipeline and dock at the construction field (site) time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is stereogram of the present invention.
The specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of portable pipeline construction welding of the present invention school mouthpart, comprise the first school circle frame 1 and the second school circle frame 2 of equal semicircular in shape structure, one end of the first school circle frame 1 and the second school circle frame 2 is hinged by the first bearing pin 3, and the other end of the first school circle frame 1 and the second school circle frame 2 is provided with jacking mechanism.
Jacking mechanism comprises jack 4, the first gripper shoe 5, the second gripper shoe 6 and two connecting plates 7, the first gripper shoe 5 is located at the end of the first school circle frame 1, one end of two connecting plates 7 is hinged by the second bearing pin 8 and the second school circle frame 2, the second gripper shoe 6 is located between the other end of two connecting plates 7, the first gripper shoe 5 and the second gripper shoe 6 be arranged in parallel, jack 4 be placed in the first gripper shoe 5 and with the second gripper shoe 6 top interference fits.
The first school circle frame 1 is identical with the second school circle frame 2 structures, and the first school circle frame 1 and the second school circle frame 2 include between 9, two semicircular plates 9 of two semicircular plates and be provided with and be evenly provided with at least two stiffeners 10.
The present invention utilizes a small-sized hydraulic jack 4, make the first school circle frame 1 and the second school circle frame 2 form a circle completing, two semicircular plates 9 of the first school circle frame 1 and the second school circle frame 2 lay respectively at the pipeline 11 and pipeline 12 ports that need welding, push up simultaneously and press the first gripper shoe 5 and the second gripper shoe 6 by the active force of hydraulic jack 4, the second gripper shoe 6 drives the second school circle frame 2 by two connecting plates 7, the first gripper shoe 5 drives the first school circle frame 1, the stressed opposite direction of the movable end of the first school circle frame 1 and the second school circle frame 2, so just can make the port of the first school circle frame 1 and the second school circle frame 2 while clamping pipe 11 and pipeline 12, make pipeline 11 and pipeline 12 ports reach concentric, and make the end face of two pipelines justify alignment in school simultaneously, thereby solve the problem of manually beaing correction that relies on, greatly improve operating efficiency, manpower and materials are saved, also be convenient to follow-up pipeline welding work simultaneously.
