Description
Technical field
The present invention relates to a kind of measurement mechanism of horizontal state length of chain cable, especially one both can have been measured length of chain cable piecemeal, also can measure the measurement mechanism of whole joint length of chain cable, belonged to 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 mooring anchor chain of the oceanographic engineering such as marine anchor chain and petroleum drilling, the single point mooring unit use of various ships use.When the regular pentagon sprocket rotation of anchor chain by anchor windlass, carry out folding and unfolding with engaging of chain ring body, in order to ensure the good engagement of positive limit five shape sprocket wheels and chain ring body, need to detect the length sum L of any five one group of chain links in anchor chain
5, L
5tolerance be+2.5% L
5, there is the accident of de-chain when avoiding the regular pentagon sprocket engagement transmission of anchor chain and anchor windlass.In addition, also need to measure the total length of anchor chain, and mooring anchor chain length can reach thousands of rice, how measuring mooring anchor chain overall length is also a great problem.
The length of five one group of chain links of existing anchor chain adopts long-rod type Special caliper to measure, and these slide calliper rule have two clamp, and one of them clamp is 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.While measuring five one group of chain ring lengths of anchor chain, adopt two people's operations, one people is resisted against the measurement face of fixed caliper in the outermost end of the 1st chain ring body, another people pulls the clamp that move about, the measurement face of clamp of making to move about is resisted against in the outermost end of the 5th chain ring body, is fixedly moving about after clamp, and long-rod type Special caliper is taken out, measure the distance between two caliper measurements faces with tape measure, this distance is the length of these five one group of chain links.There is following defect in the chain ring length that this long-rod type Special caliper measurement is five group.
1, cannot 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 hand-held long-rod type Special caliper of two people is measured, and cannot ensure the consistance of the longitudinal centre line of stock axis and tested five one group of chain links, has increased five one group chain link measurement of length error.
3, complex operation, work efficiency is very low.
In addition, as measured the length of whole joint anchor chain with this special measuring tool, operate very loaded down with trivial detailsly, efficiency is lower.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, simple operation, length of chain cable measurement mechanism that measuring error is less.
The present invention is achieved by the following technical programs:
A kind of length of chain cable measurement mechanism, comprise longeron, be fixed on longeron first end rolling support seat, be fixed on longeron the second end hold-down support, be arranged on a pair of movable clamp between rolling support seat and hold-down support and be arranged on the laser length measuring machine on one of them movable clamp, described hold-down support lower end is fixed on the fixed cross beam of horizontal anchor chain lacerating machine one end, and described rolling support seat lower end is supported on the moving beam of the horizontal anchor chain lacerating machine other end; Longeron is provided with 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 movable clamp line slideway auxiliary, the track I of longeron line slideway auxiliary is fixed in the vertical side of longeron, the slide block I of longeron line slideway auxiliary is vertical being fixedly connected with of track II with movable clamp line slideway auxiliary by web joint, and the slide block II of movable clamp line slideway auxiliary is fixedly connected with active card caliper upper end.
Object of the present invention can also further realize by following technical measures.
Aforesaid length of chain cable measurement mechanism, wherein said active card caliper is L-shaped, and L shaped first side upper end is fixedly connected with slide block II, and the L shaped Second Edge surface of a pair of active card caliper is oppositely arranged.
Aforesaid length of chain cable measurement mechanism, wherein said laser length measuring machine is fixed on a Second Edge upper end that active card caliper is L shaped, and the laser length measuring machine axis Second Edge L shaped with active card caliper surface is vertical.
Aforesaid length of chain cable measurement mechanism, wherein locates lateral pin through L shaped first side, slide block II and the track II of active card caliper, and active card caliper is fixed in track II.
Aforesaid length of chain cable measurement mechanism, wherein said rolling support seat comprises support pedestal, a pair roller, described support pedestal upper end is fixed on longeron downside, a described pair roller is supported on and is supported on pedestal both sides by roller shaft respectively, and longeron first end passes through a pair of roller supporting on the moving beam of the horizontal anchor chain lacerating machine other end.
The present invention is simple in structure, simple operation, while measuring the chain ring length of five group, a pair of movable clamp decline along track II separately, in the outermost end that the head and the tail two that make the L shaped Second Edge of a pair of active card caliper be resisted against respectively five one group of chain links having strained by anchor chain lacerating machine fixture encircle, respectively a pair of movable clamp are positioned in track II separately with locating lateral pin, the laser length measuring machine that is fixed therein an active card caliper Second Edge upper end gives off laser beam and directly projects on the L shaped Second Edge of another active card caliper, by the processing of data processing equipment, just can obtain the distance between the L shaped Second Edge of a pair of movable clamp, can directly measure the length of five one group of chain links, thereby greatly reduce owing to indirectly measuring the measuring error increasing, and can reach ± 1mm of indicating accuracy.Because rolling support seat and the hold-down support at longeron two ends are positioned at respectively on the moving beam and fixed cross beam of horizontal anchor chain lacerating machine, 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 horizontal anchor chain lacerating machine, improved measuring accuracy.
The present invention also can utilize the length of multiple one group of chain link of said method continuous coverage one assembled length, when measurement, a pair of movable clamp decline and clamp the position of the outermost end of two rings from beginning to end, give off laser beam and measure by laser length measuring machine, measurement finishes rear a pair of movable clamp and rises, anchor chain lacerating machine pushes away away this group chain link, measure the length of second group of chain link ... so repeat the linear measure longimetry of whole joint anchor chain, by the accumulation process of data processing equipment, can complete the linear measure longimetry that reaches thousands of meters of mooring anchor chains.
