Abstract
The utility model discloses a steel pipe core rod heat treatment cooling lifting appliance, which comprises a cross beam; a plurality of protrusions disposed on the cross beam, the protrusions being configured to isolate adjacent steel bars; lifting lugs arranged on two sides of the upper surface of the cross beam; and two ends of the steel cable penetrate through the lifting lugs to be fixed. According to the utility model, the steel bar is subjected to clamping force from two sides of the protrusion in the lifting process, so that tiling is realized, the process requirements are met, the lifting is convenient, and the working efficiency is high.
Description
Technical Field
The utility model relates to a lifting appliance, in particular to a steel pipe core rod heat treatment cooling lifting appliance.
Background
The steel pipe core rod is an important tool for rolling a steel pipe, is an elongated steel rod, is as long as more than 10 meters, needs to be cooled in an oil tank for 2 minutes after heat treatment and then is lifted out of the oil tank for 1 minute for cooling, then enters the oil tank for cooling for 1 minute and then is subjected to air cooling, and is circulated until the temperature is lower than 300 ℃, and a common lifting appliance can stack the steel rod in the process, so that the cooling effect is influenced, and the material structure is uneven.
Disclosure of Invention
The utility model aims to provide a steel pipe core rod heat treatment cooling lifting appliance with high working efficiency and convenient lifting so as to solve the problems in the prior art.
The utility model relates to a steel pipe core rod heat treatment cooling lifting appliance, which comprises:
a cross beam;
a plurality of protrusions disposed on the cross beam, the protrusions configured to isolate adjacent mandrels;
lifting lugs arranged on two sides of the upper surface of the cross beam;
and two ends of the steel cable penetrate through the lifting lugs to be fixed.
Further, the protrusions are narrow at the upper part and wide at the lower part, so that the upper surface of the cross beam is configured into a trapezoid groove, and the distance between two adjacent protrusions is larger than or equal to the diameter of the loaded mandrel.
The structure of the cooling lifting appliance enables the steel bars to be subjected to clamping force from two sides of the protrusion, so that tiling is realized, and stacking can be avoided.
When the steel pipe core rod comes out of the trolley type heat treatment furnace, a pair of cooling lifting slings are hung on the double-beam crane hooks, the cooling lifting slings are directly sleeved at two ends of the steel rod, the crane is lifted upwards and moved into the cooling tank in a short time, the harsh technological requirements can be met, the lifting is convenient, and the working efficiency is high.
Drawings
The embodiments of the present utility model will be described in further detail below with reference to the drawings.
FIG. 1 is a schematic diagram of an overall structure of an embodiment of the present utility model;
fig. 2 is a schematic view of a carrier according to an embodiment of the utility model.
In the figure: 1-cross beam, 2-protrusion, 3-lifting lug, 4-steel cable and 5-core rod.
Detailed Description
Referring to fig. 1 and 2, an embodiment of the steel pipe mandrel heat treatment cooling sling of the present utility model includes: the beam 1, a plurality of protrusions 2 arranged on the beam 1, lifting lugs 3 and steel ropes 4 arranged on two sides of the upper surface of the beam 1, and two ends of each steel rope 4 penetrate through the lifting lugs 3 to be fixed.
Each protrusion 2 of the hanger is narrow at the upper part and wide at the lower part, so that the upper surface of the cross beam 1 is configured as a trapezoid groove, and the distance between the adjacent protrusions 2 is larger than or equal to the diameter of the loaded mandrel 5.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
