Description

Nodular cast iron pipe cooling device Technical Field The utility model relates to the technical field of ductile cast iron pipe processing, in particular to a ductile cast iron pipe cooling device. Background In the process of processing the spheroidal graphite cast iron pipe, the pipe needs to be sprayed and cooled after being annealed by an annealing furnace. In the prior art, the pipeline is generally conveyed by a heavy chain, the pipeline cannot rotate in a spraying room, and the sprayer is generally arranged above the pipeline, so that the cooling speed of different parts of the pipeline is uneven, and the quality of the pipeline is affected. The patent of publication number CN220445014U discloses a structure that can let the pipeline spin when spraying, lets the pipeline turn up through two bearing rollers, although solved the inhomogeneous problem of pipeline cooling rate, but only a set of bearing roller, and every pipeline all need place on the bearing roller for cooling efficiency is slower, and needs additionally to set up the motor and drive the bearing roller and rotate, is unfavorable for energy-conservation. Disclosure of utility model In order to solve the problems mentioned in the background art, the utility model aims to provide a nodular cast iron pipe cooling device. In order to achieve the above object, the technical scheme of the present utility model is as follows: The utility model provides a nodular cast iron pipe cooling device, includes spray thrower and pipeline conveyor, pipeline conveyor includes chassis, brace table and chain mechanism, install at the top of chassis the brace table, the distance of brace table from the ground is along horizontally first direction taper, the spray thrower fixed set up in the top of brace table, chain mechanism has two parallel arrangement's chains that can automatic gyration, two the chain along level and perpendicular to the second direction of first direction arrange in the both sides of brace table, the chain have one section with brace table incline direction parallel support section, support section set up in the below of brace table, the interval is provided with a plurality of lugs on the outer lane of chain, works as the lug removes to when the support section, the lug salient in the brace table. Further, the chain mechanism further comprises a pair of first mounting seats, a pair of second mounting seats, a first rotating shaft, a second rotating shaft, a pair of first chain wheels, a pair of second chain wheels and a power motor, wherein the first mounting seats and the second mounting seats are arranged on two sides of the supporting table at intervals along a first direction, the first rotating shaft is rotatably mounted between the first mounting seats, the first chain wheels are coaxially fixed on the first rotating shaft, the second rotating shaft is rotatably mounted between the second mounting seats, the second chain wheels are coaxially fixed on the second rotating shaft, the first chain wheels and the second chain wheels which are opposite to each other are in transmission connection through a chain, and a main shaft of the power motor is in transmission connection with the first rotating shaft.
