Abstract
The utility model discloses a lever block usage experience teaching tool. The lever block usage experience teaching tool comprises a lever block, a tension meter and a support frame, wherein the support frame comprises an upper support component, a lower support component and two connecting components; one end and the other end of the upper support component are connected with one end and the other end of the lower support component through the two connecting components respectively; the upper connecting portion of the lever block is connected with the upper support component; the lower connecting portion of the lever block is connected with one end of the tension meter; the other end of the tension meter is connected with the lower support component. By adopting the lever block usage experience teaching tool, personnel can learn to operate the lever block, and can comprehend correct operating method of the lever block by feeling the tension change of the lever block in different operation modes.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of Lever Blocks experience teaching aid.
Background technology
As labor-intensive heavy industry industry, such as shipbuilding industry, the most educational level of its workman in First Line work is not high.For improving workman's know-how, and by its common, conventional phenomenon, rise to theoretical level, and deep understanding, the best way is realized by teaching aid intuitively exactly.
Lever Blocks is that a use is simple, Manual hoisting instrument easy to carry.The operations such as it can promote, draw, decline, calibration.Hoisting capacity is generally no more than 50 tons, is widely used in equipment installation, article lifting, parts tractive of the heavy industry industries such as shipbuilding etc.
For helping workman to grasp as soon as possible the correct using method of Lever Blocks, and stressed variation when deep Lever Blocks hoisting object, preferably realize the training to workman by teaching aid.
But existing teaching aid is mainly used in the teaching of school, too abstract, the teaching aid that does not have Lever Blocks practical operation to experience, therefore, existing teaching aid is not suitable for the workman that educational level is lower, cannot make workman experience the actual use of Lever Blocks.
Utility model content
The technical problems to be solved in the utility model is too abstract and cannot make workman that educational level is lower experience the defect of the actual use of Lever Blocks in order to overcome existing teaching aid, and a kind of Lever Blocks experience teaching aid is provided.
The utility model is to solve above-mentioned technical matters by following technical proposals:
A kind of Lever Blocks experience teaching aid, its feature is, it comprises a Lever Blocks, one tension indicator and a bracing frame, support frame as described above comprises support component on, support component and two links once, one end of described upper support component is connected with an end and the other end of described lower support parts by link described in two respectively with the other end, the upper connecting portion of described Lever Blocks is connected with described upper support component, the lower connecting portion of described Lever Blocks is connected with one end of described tension indicator, the other end of described tension indicator is connected with described lower support parts.
Preferably, a through hole is offered at the middle part of described upper support component, and the upper connecting portion of described Lever Blocks is arranged in described through hole.
Preferably, a position affixed hanger corresponding with described through hole on described lower support parts, the other end of described tension indicator is connected with described lower support parts by described hanger.
Preferably, described lower support parts are tabular, and the bottom of described lower support parts is connected with three above pulleys.
Preferably, an also affixed pushing hands of the end of described lower support parts.
Positive progressive effect of the present utility model is: employee can pass through this teaching aid learning manipulation Lever Blocks.By observing the reading of tension indicator, can know the stressed of Lever Blocks.By experiencing the tension variations of Lever Blocks under different operating mode, employee can promptly grasp the proper operation method of Lever Blocks.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Lever Blocks experience teaching aid.
The specific embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As shown in Figure 1, a kind of Lever Blocks experience teaching aid, it comprises a Lever Blocks 1, a tension indicator 2 and a bracing frame 3, bracing frame 3 comprises support component 31 on, once support component 32 and two links 33, the two ends, left and right of upper support component 31 are connected with the two ends, left and right of lower support parts 32 by two links 33 respectively, the upper connecting portion of Lever Blocks 1 is connected with upper support component 31, the lower connecting portion of Lever Blocks 1 is connected with one end of tension indicator 2, and the other end of tension indicator 2 is connected with lower support parts 32.
Like this, employee can pass through this teaching aid learning manipulation Lever Blocks.Lever Blocks is existing common equipment, just repeats no more at this.By observing the reading of tension indicator, can know the stressed of Lever Blocks.By experiencing the tension variations of Lever Blocks under different operating mode, employee can promptly grasp the proper operation method of Lever Blocks.
A through hole 311 can be offered in the middle part of upper support component 31, and the upper connecting portion of Lever Blocks 1 can be arranged in this through hole.Because the upper connecting portion of Lever Blocks is generally hook, therefore, hook can be hung on this through hole, convenient connection.
A position affixed hanger 322 corresponding with through hole 311 on lower support parts 32, the other end of tension indicator 2 is connected with lower support parts 32 by hanger 322.Because the connection end of tension indicator is generally hook-shapedly, therefore, the connecting portion of tension indicator can be connected with hanger easily.
On this basis, for convenience of this teaching aid of user's push-and-pull, can an affixed pushing hands 324 in the end of lower support parts 32.Like this, user is by pushing hands, and push-and-pull teaching aid, moves teaching aid more convenient.Pushing hands is prior art, can use existing conventional pushing hands, just repeats no more at this.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that this is only casehistory, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection domain of the present utility model.
