Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Example 1: the utility model provides a pipe welding straightener, as shown in fig. 1, including the bearing platform 1, in this embodiment, the bearing platform 1 is formed by 2 interconnect of base station such as two, a draw-in groove 21 has respectively been seted up on the bearing plane of every base station 2, draw-in groove 21 pierces through the mutually opposite sides of bearing platform 1, make take welded metal pipeline to place and to block on base station 2 and establish in draw-in groove 21, the interval between the relative inner wall of draw-in groove 21 is 3cm at least, thereby place in draw-in groove 21 that all can be stable to the tubular metal resonator body that the diameter is greater than more than 3 cm.

Two extension columns 3 are arranged between the two base platforms 2 in a penetrating mode, each extension column 3 is parallel to the length direction of the clamping groove 21, and the two extension columns 3 are symmetrically arranged on two sides of the clamping groove 21 of the base platform 2. When the staff will use the straightener, can place two base stations 2 on a horizontal plane, make the plane of accepting of two base stations 2 be located same horizontal plane, then can be according to the interval between two base stations 2 of the length adjustment of two pipelines, make the pipeline more stable when placing on corresponding base station 2, the staff is close to the welding port of two pipelines each other after that, carry out weldment work, because two welding pipeline same diameters, and hug closely in the draw-in groove 21 that corresponds base station 2, thereby guaranteed the straight each other of two pipelines, the error of making level has been reduced, make weldment work more high-efficient.

When the straightener is not used, a worker can draw out the two extension columns 3 from the two base platforms 2 and stack the two base platforms 2, so that the occupied space of the whole straightener is reduced, and the transportation efficiency is improved; on the other hand, the whole structure of the straightener is simple, if the straightener is damaged, the straightener is convenient for workers to replace, and the maintenance cost is reduced.

As shown in fig. 1, each abutment 2 is further provided with a fixing component 4 for fixing the pipeline to the abutment 2, the fixing component 4 comprises a binding band 41 and a collar 42, the binding band 41 and the collar 42 are respectively arranged at two sides of the corresponding slot 21 of the abutment 2, one end of the binding band 41 is fixed at the edge of the abutment 2, and the collar 42 is rotatably connected at the other side of the abutment 2. After the pipeline is placed in the slot 21 of the base 2, the worker can put the binding band 41 on the pipeline, penetrate into the sleeve ring 42 and bind with the sleeve ring 42, so that the pipeline is stably fixed in the slot 21 of the base 2, and the alignment error is reduced during subsequent welding.

In the welded process, can cause the residue of impurity in base station 2 draw-in groove 21 unavoidably, so the bottom surface of base station 2 draw-in groove 21 is equipped with a plurality of with the thorough blowoff hole 22 of base station 2 along the length direction interval of draw-in groove 21 to liquid impurity is convenient for also discharge, and solid impurity also drops easily.

Example 2: a pipe welding straightener, which is different from the straightener in embodiment 1, as shown in fig. 2, a magic tape 5 is provided on a binding band 41, and the magic tape 5 includes a male magic tape 515 fixed on one side of the end of the binding band 41, and a female magic tape 525 fixed on the same side of the binding band 41. When the pipeline is placed in the slot 21 of the base station 2, the worker puts the binding band 41 on the pipeline, and passes the end of the binding band 41 through the loop 42, and the male magic tape 515 at the end of the binding band 41 is adhered to the female magic tape 525, so as to achieve the effect of pipeline retention. The retention and detachment operations are also more efficient by the mutual adhesion of the male and female velcro strips 525.

As shown in fig. 2 and 3, in order to make the pipeline more labor-saving to rotate during the welding process, at least two sliding roller assemblies 6 are further arranged on each binding band 41. The roller assembly 6 includes a central shaft 61 and rotating wheels 62 coaxially rotatably connected to both ends of the central shaft 61. The straps 41 in this embodiment have a double-layered structure and are adhered to each other by the hook and loop fastener 5. The central shaft 61 is sandwiched between the two layers of the binding band 41, and the sliding of the central shaft 61 along the length direction of the binding band 41 is limited by the adhesion of the hook and loop fastener 5. When the worker fixes the pipe, the worker can adjust the position of the central shaft 61 on the binding band 41 according to the diameter of the pipe, so that when the binding band 41 fixes the pipe, the contact of the rotating wheel 62 and the pipe replaces the direct contact of the binding band 41 and the pipe, and the labor is saved in the process of welding and rotating the pipe.

As shown in fig. 2, in order to further reduce the friction force when the pipeline rotates, a plurality of pulleys 7 are respectively arranged at intervals at two edges of the clamping groove 21 of the base 2, the pulleys 7 are rotatably connected to the inner wall of the clamping groove 21 of the base 2, and the rotating shafts of the pulleys 7 in the same row are positioned on the same straight line and are parallel to the length direction of the clamping groove 21. When the pipeline was placed on the draw-in groove 21 of base station 2, the protruding border department of establishing at draw-in groove 21 of pulley 7 to replaced the direct contact at pipeline and draw-in groove 21 edge, when the pipeline rotated, reduced the frictional force at pipeline and draw-in groove 21 border, made staff's operation pipeline rotate more laborsavingly, also indirectly improved welding efficiency.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
