Abstract
The utility model provides a chain link detects card, its characteristics are including detecting the card body, establish chain link plasticity and detect the card hole with length detecting card body one side upper portion, establish the chain link diameter and detect the card hole on detecting card body opposite side, the detection blocks the hole with plasticity to establish the chain link diameter respectively in the lower part both sides of detecting the card body. The utility model discloses simple structure, convenient to use can be to chain link diameter, the plasticity of hoisting chain, and length in time detects, ensures that the hoisting chain is safe in utilization.
Description
Technical field
The utility model relates to pick-up unit, is specifically related to a kind of chain link test card, refers to a kind of test card detected jack chain.
Background technology
Jack chain is conventional in the industrial production, hoisting chain can different according to the hoisting depth playing weight can the length of adjusting chain be requisite, the important load-engaging device of crane, to the operating efficiency improving crane, the scope of work expanding crane plays an important role.Jack chain is in the process used, owing to carry heavier object, the easy stretcher strain of chain link of jack chain, long-term overload uses, easily make two chain contact place diameter serious wear of phase latch closure, like this, the weight that jack chain carries will be subject to serious impact, overweight carrying may cause jack chain to rupture, and production safety hidden danger is large.Therefore, in the process using jack chain, need to detect jack chain, get rid of potential safety hazard, guarantee jack chain use safety.
Summary of the invention
Technical problem to be solved in the utility model is a kind of chain link test card of design, utilizes this test card the extent of damage of jack chain can be detected, guarantees that jack chain is used safely.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of chain link test card, comprise test card card, chain link plastic yield length detection hole clipping is established at described test card card one upper lateral part, test card card opposite side is established chain link examine of diameter hole clipping, establishes chain ring diameter and plastic yield test card in the bottom of test card card respectively.
For the ease of depositing the utility model, establish hanging hole in described test card card upper end.
The utility model adopts the chain link test card designed by technique scheme, hole clipping is detected owing to being provided with chain link plastic yield length detection hole clipping, chain link examine of diameter hole clipping, chain ring diameter and plastic yield in test card card, in the process that jack chain uses, can to the chain ring diameter of jack chain, plastic yield, length detects in time, guarantees jack chain use safety.The utility model structure is simple, easy to use, is the ideal tools that jack chain detects.
Accompanying drawing explanation
Fig. 1 represents the structural representation of the utility model chain link test card;
Fig. 2 represents the schematic diagram of the utility model to jack chain chain link plasticity and length detection;
Fig. 3 represents the schematic diagram that the utility model detects jack chain chain ring diameter and plasticity;
Fig. 4 represents the schematic diagram of the utility model to jack chain chain link examine of diameter.
Embodiment
Illustrate below in conjunction with the structure of accompanying drawing to the utility model chain link test card.
See Fig. 1, the utility model chain link test card, comprise test card card 2, chain link plastic yield length detection hole clipping 5 is established in the side of test card card 2, the opposite side of test card card 2 is established chain link examine of diameter hole clipping 3, establishes chain ring diameter and plasticity test card 4 in the lower left side of test card card 2.Establish hanging hole 1 in the upper end of test card card 2, hanging hole 1 is convenient to deposit for being hung up by the utility model.
See Fig. 2, chain link 6, when to jack chain chain link plastic yield length detection, slowly snaps in by the utility model in chain link plastic yield length detection hole clipping 5, can not snap in if there is chain link 6, show this chain link plastic yield, chain link increases, this chain annular strain is excessive, should stop using.
See Fig. 3, the utility model is when detecting jack chain chain ring diameter and plasticity, one of two chain links connect phase latch closure end snaps in chain ring diameter and plasticity test card 4, if chain link 7 and chain link 8 end can snap in, show the wearing and tearing of this chain ring diameter and plastic yield seriously, this chain link should be stopped using.
See Fig. 4, chain link 10, when to jack chain chain link examine of diameter, slowly snaps in, can snap in if there is chain link 10 by the utility model in chain link examine of diameter hole clipping 3, shows this chain ring diameter serious wear, should stop using.
The utility model effectively can detect the length of jack chain chain link, diameter and plastic yield, can Timeliness coverage chain link institute produced problem, guarantees jack chain use safety.
Claims (2)
1. a chain link test card, comprise test card card, it is characterized in that establishing chain link plastic yield length detection hole clipping at described test card card one upper lateral part, test card card opposite side is established chain link examine of diameter hole clipping, establishes chain ring diameter and plasticity test card respectively in the both sides, bottom of test card card.
2. chain link test card according to claim 1, is characterized in that establishing hanging hole in described test card card upper end.
