Description
Technical field
The present invention relates to a kind of measurement mechanism of horizontal state length of chain cable, especially a kind ofly both can measure length of chain cable piecemeal, also can measure the measurement mechanism of whole joint length of chain cable, belong to the length measurement technique field.
Background technology
Anchor chain is the important outfititem that is related to boats and ships and oceanographic engineering safety, comprises the marine anchor chain of all kinds of boats and ships uses and the mooring anchor chain that oceanographic engineerings such as petroleum drilling, single point mooring unit are used.During the regular pentagon sprocket rotation of anchor chain through anchor windlass and the engagement of chain ring body carry out folding and unfolding, in order to ensure the good engagement of positive limit five shape sprocket wheels, need the length sum L of any five one group of chain links in the detection anchor chain with the chain ring body
5, L
5Tolerance be+2.5% L
5, the accident of taking off chain when avoiding the regular pentagon sprocket engagement transmission of anchor chain and anchor windlass.In addition, also need measure the total length of anchor chain, and the mooring anchor chain length can reach thousands of rice, how measuring mooring anchor chain length overall also is a great problem.
The length of five one group of chain links of existing anchor chain adopts the special-purpose slide calliper rule of stock formula to measure, and these slide calliper rule have two clamp, and one of them clamp is a fixed caliper, is fixed on stock one end; Another clamp are the clamp that move about, and the measurement face of clamp is vertical with stock.When measuring five one group of chain ring lengths of anchor chain, adopt two people operation, a people is resisted against the measurement face of fixed caliper on the outermost end of the 1st chain ring body; Another people spurs the clamp that move about; The measurement face of the clamp that move about is resisted against on the outermost end of the 5th chain ring body, behind the clamp that fixedly move about, the special-purpose slide calliper rule of stock formula is taken out; Measure the distance between the two caliper measurements faces with tape measure, this distance is the length of these five one group of chain links.There is following defective in the chain ring length that the special-purpose kind of calliper of this stock formula is five one group.
1, can't directly measure the length of five one group of chain links, the distance between the two caliper measurements faces that measure with tape measure is a kind of indirect measurement method, has increased measuring error.
2, the special-purpose slide calliper rule of the hand-held stock formula of two people are measured, and can't guarantee the consistance of the longitudinal centre line of stock axis and tested five one group of chain links, have increased five one group chain link measurement of length error.
3, complex operation, work efficiency are very low.
In addition, as measure the length of whole joint anchor chain with this special measuring tool, operate very loaded down with trivial detailsly, efficient is lower.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, simple operation, the less length of chain cable measurement mechanism of measuring error.
The present invention is achieved through following technical scheme:
A kind of length of chain cable measurement mechanism; Comprise longeron, be fixed on longeron first end the rolling supporting seat, be fixed on longeron second end hold-down support, be arranged on a pair of movable clamp between rolling supporting seat and the hold-down support and be arranged on the laser length measuring machine on one of them movable clamp; Said hold-down support lower end is fixed on the fixed cross beam of horizontal anchor chain lacerating machine one end, and said rolling supporting seat lower end is supported on the moving beam of the horizontal anchor chain lacerating machine other end; Longeron is provided with the longeron line slideway auxiliary; Movable clamp comprise that the movable clamp line slideway auxiliary, the upper end that intersect vertically with longeron are fixed on the active card caliper on the movable clamp line slideway auxiliary; The track I of longeron line slideway auxiliary is fixed on the vertical side of longeron; The slide block I of longeron line slideway auxiliary is connected with the track II vertical fixing of movable clamp line slideway auxiliary through web joint, and the slide block II of movable clamp line slideway auxiliary is fixedly connected with active card caliper upper end.
The object of the invention can also further realize through following technical measures.
Aforesaid length of chain cable measurement mechanism, wherein said active card caliper is L-shaped, and L shaped upper end, first limit is fixedly connected with the slide block II, and the L shaped surface, second limit of a pair of active card caliper is oppositely arranged.
Aforesaid length of chain cable measurement mechanism, wherein said laser length measuring machine are fixed on a upper end, second limit that the active card caliper is L shaped, the second limit Surface Vertical that laser length measuring machine axis and active card caliper are L shaped.
Aforesaid length of chain cable measurement mechanism is wherein located lateral pin and is passed the first L shaped limit of active card caliper, slide block II and track II, and the active card caliper is fixed on the track II.
Aforesaid length of chain cable measurement mechanism; Wherein said rolling supporting seat comprises support pedestal, a pair roller; Said support pedestal upper end is fixed on the longeron downside; A said pair roller is supported on through roller shaft respectively and supports on the pedestal both sides, and longeron first end is supported on the moving beam of the horizontal anchor chain lacerating machine other end through a pair roller.
Simple in structure, the simple operation of the present invention; When measuring five one group chain ring length; A pair of movable clamp descend along track II separately, on the outermost end that the head and the tail two that make the second L shaped limit of a pair of active card caliper be resisted against five one group of chain links that pass through the tension of anchor chain lacerating machine anchor clamps respectively encircle, respectively a pair of movable clamp are positioned on the track II separately with the location lateral pin; The laser length measuring machine that is fixed therein upper end, active card caliper second limit gives off laser beam and directly throws on L shaped second limit of another active card caliper; Through the processing of data processing equipment, just can obtain the distance between L shaped second limit of a pair of movable clamp, can directly measure the length of five one group of chain links; Thereby reduced greatly owing to the measuring error of measuring increase indirectly, and indicating accuracy can reach ± 1mm.Because on the rolling supporting seat at longeron two ends and the moving beam and fixed cross beam that hold-down support is positioned at horizontal anchor chain lacerating machine respectively; Guarantee longitudinal centre line of the present invention and the consistance that is positioned at five the tested one group of chain link longitudinal centre lines within the horizontal anchor chain lacerating machine, improved measuring accuracy.
The length of a plurality of one group of chain link of the present invention's said method continuous coverage also capable of using one assembled length; During measurement, a pair of movable clamp descend and clamp the position of the outermost end of two rings from beginning to end, give off laser beam through laser length measuring machine and measure; Measure and finish a pair of movable clamp rising in back; Anchor chain lacerating machine pushes away away this group chain link, measures the length of second group of chain link ..., so repeat to accomplish the linear measure longimetry of whole joint anchor chain; Through the accumulation process of data processing equipment, can accomplish the linear measure longimetry that reaches thousands of meters mooring anchor chains.
