Two ends, and at the same time being located at the upper surface of crossbeam 1.At this point, one end of tensiometer 4 is connect with the first column 2, the other end with
Cucurbit 5 to be measured connects, and the other end guide chain of cucurbit 5 to be measured is connect with the second column 3, thus by 5 edge of tensiometer 4 and cucurbit to be measured
Horizontal direction is fixed between the first column 2 and the second column 3, and then can be carried out in the horizontal direction to cucurbit 5 to be measured
Lateral pull test.
In other embodiments, it can also be welded and fixed by the length of increase the first column 2 and the second column 3
In two ends of crossbeam 1, to provide the support force of horizontal direction to the first column 2 and the second column 3 using crossbeam 1, protect
Demonstrate,prove the stability of the first column 2 and the second column 3.
Next, when to carrying out the pull test of cucurbit to be measured using the lateral pull test-bed of the utility model, to
The stress condition for surveying cucurbit is analyzed.
As shown in connection with fig. 2, during the test, cucurbit 5 to be measured mainly by along straight down self gravity G and edge
The pulling force F of guide chain and tensiometer direction leads to pulling force F and horizontal direction shape at this time due to the presence of cucurbit self gravity to be measured
At angle α.At this point, carry out lateral pull test to the cucurbit of different model, and to the rated load of cucurbit to be measured, tensiometer
Numerical value and the angle α of generation are for statistical analysis, obtain the data in table 1.
Table 1
According to the test to different size cucurbit it is found that the angle α due to caused by cucurbit self gravity is very little, and
Error between the cucurbit value of thrust obtained at this time by tensiometer actual measurement and its rated load is somebody's turn to do within 0.01%
Error is negligible in cucurbit use process.Therefore, being using the lateral pull test-bed of the utility model can
To carry out accurate pull test to cucurbit.
As shown in connection with fig. 1, in the present embodiment, crossbeam 1 selects H profile steel material, and makes the web 11 in H profile steel in perpendicular
Histogram carries out the placement of horizontal direction to crossbeam 1 to state, can utilize the counter-bending of entire crossbeam 1 to greatest extent in this way
Ability fights cucurbit 5 to be measured and passes through the bending force that two columns generate, to guarantee the safety of entire lateral pull test-bed
Reliability.
At the same time, the first column 2 and the second column 3 can use plate structure, and keep same flat with web 11
The positional relationship vertical welding in face is fixed on the upper surface of crossbeam 1, so that the first column 2 and the second column 3 itself be made to form one
A class reinforcing plate structure further promotes the ability that entire test-bed resists the pulling force that cucurbit 5 to be measured generates, guarantee test process
In entire test-bed stability.
As shown in connection with fig. 1, in the present embodiment, a lifting lug 6 is offered respectively on the first column 2 and the second column 3,
In order to carry out the connection of the dismounting between column and tensiometer 4 and cucurbit to be measured 5, operating efficiency is improved.Equally, in other implementations
In example, lifting lug 6 can also be fixed on the first column 2 and the second column 3 by the way of welding.
The lateral pull test-bed of the utility model can also use structure as shown in Figure 3, i.e. the first column 2 and the
Detachable connection is respectively adopted with crossbeam 1 in two columns 3, thus can be according to the difference of cucurbit 5 to be measured, to the first column 2
The distance between second column 3 is adjusted, to obtain optimal test effect, and meets more different model cucurbits
Experiment work, to improve the service efficiency of entire test-bed.
As shown in connection with fig. 3, multiple pin shaft holes 12 are equipped on crossbeam 1, and multiple pin shaft holes 12 are along the length side of crossbeam 1
It is equipped with the first connecting hole to distribution, while in the lower end position of the first column 2, is equipped with second in the lower end position of the second column 3
Connecting hole.At this point, the company between the first column 2 and crossbeam 1 can be completed through the first connecting hole and pin shaft hole 12 by pin shaft 7
It connects, the connection between the second column 3 and crossbeam 1 can be completed through the second connecting hole and pin shaft hole 12 by pin shaft 7.At this point,
By change the run through different location of pin shaft 7 pin shaft hole 12, can between the first column 2 and the second column 3 it is final away from
Change is adjusted from relationship.
Preferably, in the present embodiment, crossbeam 1 equally selects H profile steel, but at this point, by the state in horizontal direction of web 11
It places, the upper surface of crossbeam 1 can be made to form sliding slot 13 in this way.At the same time, by the lower end of the first column 2 and the second column 3
Face is directly contacted with the slot bottom of sliding slot 13, to improve column pair using the lower end surface of the first column 2 and the second column 3
The tensile capacity of cucurbit 5 to be measured guarantees the stability of the first column 2 and the second column 3.
It equally, in other embodiments, can also be by vertical on the lower end position of the first column 2 and the second column 3 edge
More than two connecting holes are arranged in direction, while the pin shaft hole of identical quantity and position being arranged on crossbeam 1, thus by more
Pin shaft the first column 2 and the second column 3 are fixedly connected with crossbeam 1, and then improve column to the tension of cucurbit 5 to be measured
Ability.
