Description

Hanger for galvanizing of bent pipe

Technical Field

The invention belongs to the technical field of galvanizing bearing, and particularly discloses a hanger for galvanizing a bent pipe.

Background

The pipe is a necessary material for building engineering, and commonly used materials comprise a water supply pipe, a water discharge pipe, a gas pipe, a heating pipe, an electric wire conduit, a rainwater pipe and the like. In order to adapt to complicated structural terrains, bends are often used to achieve steering during transportation.

The shape structure of the elbow pipe commonly seen in the prior art is an Jiong-shaped pipe with two ends bent towards the same side, and through holes are arranged at two axial ends. In order to prevent rusting, the surface of the elbow needs to be galvanized, and meanwhile, the galvanized layer on the surface of the elbow can play a certain role in beauty. When the bent pipe is galvanized, the conventional process is to hang the bent pipe by using an iron wire and hang the bent pipe downwards into a galvanizing bath by a crane for galvanizing. According to the galvanizing mode, the number of bent pipes hung at one time is small, so that the production efficiency is low, iron wire traces are formed on the surfaces of the bent pipes after galvanizing, the galvanizing quality is influenced, and in addition, the bent pipes are hung by the iron wires and are easy to loosen, so that certain potential safety hazards are realized.

Disclosure of Invention

The invention aims to provide a hanger for galvanizing a bent pipe, which solves the problem of unstable bent pipe fixation.

In order to achieve the purpose, the basic scheme of the invention is as follows: a hanging tool for galvanizing a bent pipe comprises a supporting frame, wherein two layers of a plurality of supporting rods are respectively fixed in the supporting frame from top to bottom, the upper layer of supporting rods and the lower layer of supporting rods are parallel to each other, the supporting rod positioned on the upper layer is a first supporting rod, the supporting rod positioned on the lower layer is a second supporting rod, the first supporting rod and the second supporting rod are staggered with each other in the vertical direction, and a plurality of first vertical columns which are parallel to each other are respectively and sequentially fixed on the first supporting rod along the axial direction; a plurality of second vertical columns which are parallel to each other are sequentially fixed on the second supporting rod along the axial direction; the first upright columns and the second upright columns are staggered in the vertical direction.

The working principle and the beneficial effects of the basic scheme are as follows: 1. this technical scheme utilizes upper bracing piece and lower floor's bracing piece crisscross on the direction of height, realizes that the slope of return bend on the bracing piece is fixed, specifically is the first half outer wall of bracing piece and supports the outer wall that leans on at upper bracing piece, and the latter half outer wall of bracing piece supports the outer wall that leans on at lower floor's bracing piece, finally realizes the technological effect that the return bend slope was placed. And meanwhile, an additional upright post is additionally arranged on the lower-layer supporting rod to further fix the bent pipe. Because the both ends of return bend are crooked, therefore the one end of return bend when inserting the stand, the outer wall of the interlude of return bend can also be complete to lean on the outer wall of upper bracing piece. This scheme utilization stand and the grafting of return bend tip to the realization plays further fixed to the return bend, avoids the return bend to appear squinting in vertical direction. An additional upright post is additionally arranged on the outer wall of the upper layer supporting rod, and the upright post and the lower layer supporting rod are mutually staggered to fix the upper half part of the bent pipe. The upper half part of the elbow leans on the upper supporting rod, the elbow is located between the adjacent stand columns, and therefore limiting effect on limiting transverse deviation of the elbow is achieved.

Has the advantages that: this technical scheme realizes the relative slip of second stand through adopting fixed rod and sleeve sliding connection's mode, effectively improves the flexible degree that the second stand is adjustable, realizes adjusting the axial length of second stand according to the size of return bend, avoids the return bend to occupy too big hanger space.

Furthermore, a pressure spring is fixedly connected between the inner wall of the sleeve and the free end of the fixed rod.

Has the advantages that: according to the technical scheme, the automatic resetting function of the sleeve and the fixed rod is realized by adopting the technical mode of additionally arranging the pressure spring, and the length of the second stand column is contracted only under the condition of loading the bent pipe.

Furthermore, the free ends of the first upright post and the second upright post are both hemispherical curved surfaces.

Has the advantages that: this technical scheme adopts the structure of spherical curved surface to reduce the edge of stand, avoid causing the damage to the return bend because of the edge of stand.

Furthermore, the included angle between the central axis of the first upright post and the horizontal plane of the second upright post is 5-30 degrees.

Has the advantages that: this technical scheme is through the inclination of optimizing the stand to when guaranteeing return bend slope fixed action, also can avoid because of the too big problem that leads to the return bend landing of inclination.

Further, first stand all is equipped with a plurality of granule archs with the second stand outer wall.

Has the advantages that: this technical scheme is protruding through add the granule at the outer wall of stand to increase the frictional force between stand and the return bend, improve the stand and to the fixed stability of return bend.

Further, the support frame is of a cuboid frame-shaped structure.

Has the advantages that: this technical scheme adopts the support frame of cuboid frame column structure, has the advantage that simple structure is convenient for machine-shaping on the one hand, and on the other hand also because cuboid looks adjacent surface mutually perpendicular to the fixed of support frame of putting.

Furthermore, a hanging lug is welded and fixed at the top end of the support frame.

Has the advantages that: this technical scheme utilizes the hangers of fixing on the support frame, realizes utilizing the hangers to the purpose of hanging of support frame to the operating personnel transport shifts the support frame.

Furthermore, a cushion block is welded and fixed at the bottom of the support frame.

Has the advantages that: this technical scheme is through at the bottom welded fastening cushion of support frame to the realization utilizes the cushion and meets the department with horizontal ground, with the stability of reinforcing the support frame under the static state of placing.
