Abstract
The invention relates to a pitch length measuring device of a chain, and belongs to the technical field of chain length measurement. The measuring device is designed by utilizing the principle that bearing of the chain is vertical due to the self-gravity of the chain. The measuring device comprises an upper hanging chain head, a lower hanging chain head, a slide block, a linear guide rail, a scale and a frame. The false collapse phenomenon caused by lack of external tensioning force in a traditional horizontal laying manner is effectively avoided, the accuracy of measuring data is ensured, the workload and work intensity are greatly reduced, and the work efficiency is improved.
Description
Technical field
The present invention relates to chain length field of measuring technique, be specifically related to a kind of chain pitch length measurement device.
Background technology
At present, chain, as a kind of common industrial auxiliary products, is widely used in each operating mode fields such as transport, transmission, towing, lifting.Along with the development of industrial technology and improving constantly of requirement, in recent years, every profession and trade to chain demand in continuous lifting, thus, also increasing to the work of chain pitch standardization of length, both comprise the calibrating of produceing enterprises of chain in daily production run, also comprise chain user to workplaces such as the reinspections of chain pitch size.
Chain pitch linear measure longimetry mode traditional is at present, chain is laid on the ground, as shown in Figure 1, with slide calliper rule 101 slide calliper rule bipod is inserted inside the chain link 102 liang of end links that need measure, slide calliper rule read measured chain link several in long, and then draw single chain link pitch.This mode stretches owing to not applying external force, cannot ensure that chain is tightened completely, chain may be caused to cause measurement data inaccurate because of loose, and manual labor amount is larger when therefore measuring.
Therefore, how for chain inspection work provides a kind of new instruments of inspection, to improve test data accuracy rate and work efficiency, technical matters urgently to be resolved hurrily is become.
Summary of the invention
(1) technical matters that will solve
The technical problem to be solved in the present invention is: how to design a kind of novel chain length measuring equipment, effectively avoid because of chain tile time because measuring the problem of misalignment without external force tensioning, ensure test data true and accurate, and reduce manual operation amount and operation intensity, increase work efficiency.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of chain pitch length measurement device, comprising: upper chaining head 1, lower chaining head 2, slide block 3, line slideway 4, scale 5 and frame 6;
Described upper chaining head 1 is fixed on the vertical portion of frame 6, is the stiff end of tested chain 7; Described line slideway 4 is fixed in frame 6, and vertical with the horizontal base of frame 6; Described scale 5 is fixedly connected with frame 6, and vertical with the horizontal base of frame 6; Described slide block 3 can slide up and down on line slideway 4; Described lower chaining head 2 is fixed on slide block 3, and parallel with the horizontal base of frame 6.
Preferably, the upper surface of described scale 5 flushes with the upper surface of upper chaining head 1, and lower end is connected with the horizontal base of frame 6.
Preferably, described upper chaining head 1 is bolted the vertical portion being fixed on frame 6.
Preferably, described line slideway 4 is bolted and is fixed in frame 6.
Preferably, described lower chaining head 2 is bolted and is fixed on slide block 3.
(3) beneficial effect
The present invention utilizes chain to conduct oneself with dignity and ensures its stressed vertical principle, devise a kind of novel chain length measuring equipment, effectively prevent traditional tile mode " void is collapsed " phenomenon because occurring without external force tensioning, thus ensure that the accuracy of measurement data, simultaneously, significantly reduce again manual operation amount and operation intensity, improve work efficiency.

Embodiment
For making object of the present invention, content and advantage clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As shown in Figure 2, the chain pitch length measurement device that the embodiment of the present invention provides comprises: upper chaining head 1, lower chaining head 2, slide block 3, line slideway 4, scale 5 and frame 6.In figure 7 is tested chain.
Described upper chaining head 1 is fixed on the vertical portion of frame 6, is the stiff end of tested chain 7; Described line slideway 4 is bolted and is fixed in frame 6, and vertical with the horizontal base of frame 6; Described scale 5 is fixedly connected with frame 6, and vertical with the horizontal base of frame 6; Described slide block 3 can slide up and down on line slideway 4; Described lower chaining head 2 is fixed on slide block 3, and parallel with the horizontal base of frame 6.
In use, the initial chain link of tested chain 7 is hung on upper chaining head 1 place, after the selected pitch quantity that will measure, lower chaining head 2 is inserted in tested chain termination chain link, the data indicated on scale by reading lower chaining head 2 draw tested chain resultant pitch length, and then can draw single chain link pitch.In measuring process, because tested chain 7 is vertical mode of placing, and upper end is fixed, therefore because traditional tile mode " void is collapsed " phenomenon because occurring without external force tensioning can not occur gravity principle, thus ensure that the accuracy of measurement data, meanwhile, significantly reduce again manual operation amount and operation intensity, improve work efficiency.
It should be noted that, in the present embodiment, the upper surface of scale 5 flushes with the upper surface of upper chaining head 1, lower end is connected with the horizontal base of frame 6, such set-up mode makes the data that only need read indicated by lower chaining head 2 namely can be used as tested chain resultant pitch length, and do not need two data values that chaining head 1 and lower chaining head 2 indicate respectively, then subtract each other, improve measurement efficiency.
In addition, in the present embodiment, described upper chaining head 1 is bolted and is fixed in frame 6, described lower chaining head 2 is bolted and is fixed on slide block 3, therefore, can, conveniently by changing the upper chaining head 1 of different specification size and lower chaining head 2, realize measuring the pitch of the tested chain 7 of any specification, mainly comprise multiple specification such as D60mm, D48mm, D42mm, D38mm, D34mm, be applicable to the inspection field of ring type chain.
As can be seen from the above embodiments, the present invention utilizes chain to conduct oneself with dignity and ensures its stressed vertical principle, devise a kind of novel chain length measuring equipment, effectively prevent traditional tile mode " void is collapsed " phenomenon because occurring without external force tensioning, thus ensure that the accuracy of measurement data, meanwhile, significantly reduce again manual operation amount and operation intensity, improve work efficiency.And easy to detect, applicability is wide.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
