Description
Technical field:
The utility model relates to belt conveyor checkout equipment technical field, particularly relates to a kind of belt conveyor intermediate roll static equilibrium cubing.
Background technology:
Belt conveyor is the major equipment of modern bulk material transportation; Being widely used in industries such as metallurgy, mine, coal, harbour, chemical industry, water conservancy, electric power, papermaking, is the important composition parts of belt conveyor as cylinder, the speed-raising of the modernization of industry in recent years increase to rubber conveyor require increasingly high; The sealing-tape machine of large conveying quantity, big bandwidth, high-speed, electromechanical integration, long distance uses more and more widely; Corresponding cylinder is the vitals of sealing-tape machine, and to designing and producing of it, quality requirements is also increasingly high; Torque resistant power, static equilibrium etc. are the important detection indexs of sealing-tape machine swift; Rubber conveyer is that 2000mm is designed to 2800mm now from the past maximum bandwidth, and belt speed is 7.5m/s from the 2.5m/s growth in past, and statically balanced detection is more particularly important.
Referring to Fig. 1 and Fig. 2; Two good optical axis 1,1a of mill of existing cylinder static equilibrium detection employing are clipped in two bearing supports 2,2a is last; Measured cylinder 3 spacings, the axle head at cylinder 3 two ends has been seated in last and adjustment cylinder 3 levels of optical axis 1,1a of bearing support 2,2a, made cylinder 3 gravity perform mark downwards; Rotating 90 ° makes the gravity mark to the surface level position; And adopt magnet to carry out counterweight the other side of mark, and calculate eccentric throw according to the weight of magnet, satisfy the requirement of G40 balance quality in the GB/T10595-2009 standard.There is following shortcoming in the existing cubing of measuring, at first is to surpass 1000mm for φ 630 diameter of cylinder, and the diameter of axle surpasses the cylinder of φ below 200; Two optical axises that are seated on the frame like this can be kept to measure and use; But just not enough to the drum shaft rotation distance of φ more than 200, optical axis will extend, otherwise can not rotary drum gravity to horizontal level; Poor safety performance during next cylinder measuring stationary balance; The cylinder rotary gravity rolls out on two optical axises by motion on the rectilinear direction easily, causes security incident, brings difficulty and potential safety hazard to surveying work.
The utility model content
The utility model technical matters to be solved is to the existing existing problem of cylinder static equilibrium cubing a kind of new cylinder static equilibrium cubing to be provided.This cylinder static equilibrium cubing changes the measurement that rotatablely moves into by the rectilinear motion measurement; When diameter of cylinder surpasses 1000mm, when the diameter of axle surpasses φ 200mm, be rotated the static equilibrium measuring method; Improved the security measurement coefficient; Remedied the deficiency of measuring method, improved the work efficiency of measuring, measuring accuracy has also reached the requirement of standard code G40.
The utility model technical matters to be solved can realize through following technical scheme:
Cylinder static equilibrium cubing is divided into structure and identical two groups measures support components, measures support component for every group and comprises bracing frame and be installed in the bearing seat on the support frame as described above and be installed in the pair of bearings on the said bearing seat through lead screw transmission mechanism.
When utilizing the utility model to measure the cylinder static equilibrium, at first according to the external diameter of cylinder, through the height of lead screw transmission mechanism regulating shaft bearing; Then with the axle head frame at cylinder two ends between two groups of pair of bearings of measuring support components, on two groups of bearing supports of measuring support components, set up a frame level and make frame level place straight line on the cylinder, planar horizontal on the adjustment cylinder; Let the axle head at cylinder two ends on bearing, rotate freely, center of gravity power is downward, can begin to carry out the cylinder static equilibrium and measure; During measurement cylinder gravity is performed sign, rotary gravity to 90 ° horizontal level increases the weight of with magnet 90 ° of relative opposite location with magnet; Cause cylinder gravity not rotating, magnet weight is measured the statically balanced balancing gravity value of cylinder exactly, and RQ≤GL calculates through formula; Wherein: R is a radius roller; Q is an equilibrium value, and G is the cylinder quality, and L is an eccentric throw; Whether eccentric throw surpasses the permissible value of G40 regulation in the GB/T10595-2009 standard, thereby reaches the requirement of measuring and using.
The cylinder static equilibrium cubing of the utility model is rotated by straight line and is changed rotary movement into, and two optical axises being processed by original mill change two bearings idler pulley axle into, and safety coefficient has increased, and has guaranteed security and the reliability measured.Balance quality and work efficiency have also been improved.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 3 and Fig. 4; The cylinder static equilibrium cubing of the utility model; Be divided into structure and identical two groups measure support components, measure support component for every group and comprise bracing frame 10 and be installed in the bearing seat 30 on the bracing frame 10 and be installed in the pair of bearings 41,42 on the bearing seat 30 through lead screw transmission mechanism 20.
When measuring cylinder 50 static equilibrium; At first according to the external diameter of cylinder 50; Through the height of lead screw transmission mechanism 20 regulating shaft bearings 30, then the axle head frame at cylinder 50 two ends is measured the pair of bearings 41 of support component at two groups, between 42, on the bearing support 10 of two groups of measurement support components, set up a frame level and make frame level place straight line on the cylinder; Planar horizontal on the adjustment cylinder; Let the axle head at cylinder 50 two ends on bearing 41,42, rotate freely, center of gravity power is downward, can begin to carry out the cylinder static equilibrium and measure.During measurement cylinder gravity is performed sign, rotary gravity to 90 ° horizontal level increases the weight of with magnet 90 ° of relative opposite location with magnet; Cause cylinder gravity not rotating, magnet weight is measured the statically balanced balancing gravity value of cylinder exactly, and RQ≤GL calculates through formula; Wherein: R is a radius roller; Q is an equilibrium value, and G is the cylinder quality, and L is an eccentric throw; Whether eccentric throw surpasses the permissible value of G40 regulation in the GB/T10595-2009 standard, thereby reaches the requirement of measuring and using.
The cylinder static equilibrium cubing and the former cylinder static equilibrium cubing of the utility model are compared measurement, can satisfy the measuring accuracy requirement fully, also improve to some extent.
For example: adopt former cylinder static equilibrium cubing to measure φ 630 diameter cylinders, the cylinder quality is 800Kg, adjusts the cylinder horizontal level and makes cylinder gravity downward; Rotary drum gravity to 90 ° horizontal level; Increase the weight of with magnet 90 ° of relative opposite location with magnet, cause cylinder gravity not rotating, magnet weight is 2.31Kg; RQ≤GL calculates through formula, L=315 * 2.31 ÷ 800=0.9096mm.
Adjust the cylinder horizontal level when adopting the utility model to measure; Make cylinder gravity downward, rotary drum gravity to 90 ° horizontal level increases the weight of with magnet 90 ° of relative opposite location with magnet; Cause cylinder gravity not rotating; Magnet weight is 2.8Kg, and RQ≤GL calculates through formula, L=315 * 2.8 ÷ 800=1.1025mm
Facts have proved that the cylinder static equilibrium measuring accuracy that rotatablely moves has improved 0.0904mm, satisfies the requirement of G40 balance quality in the GB/T10595-2009 standard fully.
