Abstract
The utility model discloses a measuring device of rolling mill roll gap, which comprises a hydraulic cylinder, a displacement sensor, au auxiliary cylinder, wherein the auxiliary cylinder is arranged on the external part of the hydraulic cylinder, the displacement sensor is arranged on the top of the auxiliary cylinder, a cylinder body and a piston of the auxiliary cylinder are fixedly connected with these of the hydraulic cylinder. The displacement senor is sleeved on a magnetic ring of the auxiliary cylinder, non-magnetic spacers are arranged on upper-lower two planes of the magnetic ring, and the magnetic ring is connected with the piston of the auxiliary cylinder through a non-magnetic fixed bolt. The cylinder body and the piston of the auxiliary cylinder are respectively connected with these of the hydraulic cylinder through a connecting sheet and the fixed bolt, the connecting sheet is fixedly connected through the fixed bolt.
Description
Technical field
The utility model relates to a kind of displacement measuring device, relates in particular to a kind of measurement mechanism of mill roll-gap, is applicable to the iron and steel production field.
Background technology
Steel rolling AGC displacement transducer is one of most important instrumentation in the steel rolling production process, detects the displacement of cylinder by position measurement, produces and can't carry out if displacement transducer breaks down.Measure roll gap at present and all be installed in the position that the AGC oil cylinder is inner to be hit exactly with displacement transducer, have following shortcoming: 1, built-in displacement transducer is changed difficulty, needs to shut down more than two hours, has a strong impact on output and economic benefit.2, the change bit displacement sensor amount of labour is big, needs a plurality of work posts to cooperate and finishes, and have major safety risks when changing.3, the installation site humidity of displacement transducer, stuffy, environment temperature is higher, influences its service life, and can't carry out the daily maintenance of patrolling and examining to it.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of installation is provided, safeguards the measurement mechanism of steel rolling rolling mill roll roll gap simply and easily.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of measurement mechanism of mill roll-gap comprises hydraulic jack, displacement transducer, auxiliary cylinder, and described auxiliary cylinder is arranged on the outside of hydraulic jack; Described displacement transducer is arranged on the top of auxiliary cylinder; The cylinder body of auxiliary cylinder and piston are fixed together with the cylinder body and the piston of hydraulic jack respectively.
Described displacement transducer is enclosed within on the magnet ring of auxiliary cylinder; The upper and lower surface of described magnet ring is provided with non-magnetic conduction pad; Magnet ring is connected by non-magnetic conduction set bolt with the piston of auxiliary cylinder.
The cylinder body of described auxiliary cylinder and piston are fixedlyed connected with the cylinder body and the piston of hydraulic jack respectively by brace and set bolt; Described brace is fixedly connected by set bolt.
Described hydraulic jack is the AGC hydraulic jack.
Move up and down in the process auxiliary cylinder by the same moved further of brace at the AGC hydraulic jack, the displacement that auxiliary cylinder produces is measured in the relative motion of displacement transducer and magnet ring, measure the actual displacement amount of AGC hydraulic jack indirectly, thus the motion that draws roller gap.
The beneficial effects of the utility model be simple in structure, make simple and easyly, the change bit displacement sensor is easy, maintaining is convenient, helps improving production operational availability and increases economic efficiency.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
In Fig. 1, a kind of measurement mechanism of mill roll-gap comprises hydraulic jack 5, displacement transducer 1, auxiliary cylinder 2, and hydraulic jack 5 is the AGC hydraulic jack.Auxiliary cylinder 2 is arranged on the outside of hydraulic jack 5; Before improving, displacement transducer 1 is arranged on the former displacement transducer installation site 6 at top of hydraulic jack 5; After the improvement, displacement transducer 1 is arranged on the top of auxiliary cylinder 2; The cylinder body of auxiliary cylinder 2 and piston 8 are fixed together with the cylinder body and the piston 9 of hydraulic jack 5 respectively.
Displacement transducer 1 is enclosed within on the magnet ring 4 of auxiliary cylinder 2; The upper and lower surface of magnet ring 4 is provided with non-magnetic conduction pad; Magnet ring 4 is connected by non-magnetic conduction set bolt with auxiliary cylinder piston 8.
The cylinder body of auxiliary cylinder 2 and piston 8 are fixedlyed connected with the cylinder body and the piston 9 of hydraulic jack 5 respectively by brace 7 and set bolt 3; Described brace 7 is fixedly connected by set bolt 3.
Auxiliary cylinder 2 the insides do not have hydraulic oil.
In implementation process auxiliary cylinder 2 be connected with hydraulic jack 5 want firmly, no free gap, brace 7 will be lacked and the intensity and the good rigidly of brace 7 materials, with assurance displacement transducer 1 accuracy of detection.
