Abstract

The utility model relates to a load test device, which comprises a structure or device (1) to be tested and a chain block (2), wherein the chain block (2) is connected at the lower end of the structure or device (1) to be tested, the lower end of the chain block (2) is provided with a drawing force gauge (3), the lower end of the drawing force gauge (3) hooks a fixed body (4) via a drag hook, and the fixing body (4) is fixed on the ground; and the structure or device (1) to be tested is a large and small equipment lifting hook or a hanging bracket or a hoisting machine. The utility model makes the test process safer and the result more accurate.

Description

A kind of lift heavy load test device

Technical field

The utility model belongs to a kind of test unit, particularly relates to a kind of lift heavy load test device.

Background technology

According to the requirement of job specifications,, in engineering, usually need the support bracket of pre-buried load-bearing suspension hook, equipment and large-scale electrolier etc. are carried out the lift heavy load test from security.Such as the jet blower in the tunnel, before installation, should do the loading test of supporting structure, the structural strength of supporting blower fan should guarantee at more than 15 times of actual loading.Fixing and the suspension apparatus of large-scale festive lantern, job specifications requires and should do overload test by 2 times of light fixture weight.Whether the fixing and suspension apparatus of large-scale light fixture meets the drawing requirement by the job design pre-buried installation of publishing picture after as calculated for checking its firm program, so should do overload test, is for safe in utilization equally.

Adopt traditional lift heavy load test device, general by hanging the counterweight of predetermined weight from above, to reach the purpose of load test.But when carrying out large-tonnage lift heavy load test, usually waste lot of manpower and material resources in order to seek mass, and consider on-the-spot environmental factor, and on-the-spot whether having ready conditions can be satisfied the smooth implementation of this scheme, and it is helpless owing to the mass that can't find coupling that What is more.And on-the-spot large-tonnage counterweight carrying is inconvenient, and the degree of accuracy of weight is inaccurate simultaneously.The scene does not have the standard counterweight usually, generally does the load weight with heavier steel plate and coil of strip, bundled article such as reinforcing bar, and deviation is bigger between the weight of mass and the weight of testing requirements.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of lift heavy load test device, makes process of the test safer, and the result is more accurate.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of lift heavy load test device, comprise by geodesic structure or device and chain block, described chain block is connected by the lower end of geodesic structure or device, the tautness meter scale is installed in the lower end of described chain block, fixed body is caught on by drag hook in described tautness meter scale lower end, and described fixed body fixes on the ground.

Described is big mini-plant suspension hook or pipe-hanging hook or hoisting machinery by geodesic structure or device.

Beneficial effect:

A kind of lift heavy load test device of the present utility model, more accurate on the data of measuring than conventional apparatus.In the process of measuring,, can not take place to be can't stand that owing to holding pulling force causes dropping of load-bearing thing that the generation security incident is than conventional apparatus safety and reliability by geodesic structure or device because what use is fixed body.More science, easier enforcement on the environmental factor (whether can be transported to tensile test scene etc. smoothly as the object that is replaced) of mode of measuring and consideration has reduced the preparation and the transportation of mass.

Description of drawings

Fig. 1 is the synoptic diagram of the utility model lift heavy load test.

Among the figure: 1-is by geodesic structure or device, 2-chain block, 3-pulling force quantifier, 4-fixed body

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

A kind of lift heavy load test device, comprise by geodesic structure or install 1 and chain block 2, described had described chain block 2 by geodesic structure or device lower end, tautness meter scale 3 is installed in the lower end of described chain block 2, fixed body 4 is caught on by drag hook in described tautness meter scale 3 lower ends, and described fixed body 4 fixes on the ground.

Described all kinds of load is or big mini-plant suspension hook or pipe-hanging hook or hoisting machinery.

Embodiment 1

As shown in Figure 1, a kind of with the test of jet blower as load, described jet blower weight is 548kg, weight support frame is 85kg, general assembly (TW) is 633kg, needing to beat setscrew or plantation chemical anchor bolts is 20 (decide on field condition, just firmly then can use chemical anchor bolts inadequately as basic originally, generalized case only needs setscrew to get final product).With chemical anchor bolts is example: adopt M12 * 160mm.5.8 level galvanized steel chemical anchor bolts fixation, blower fan is installed the loading test of previous crops supporting structure, and the structural strength of supporting blower fan should guarantee at more than 15 times of actual loading.Consider straightway testing pulling force 9495kg on this basis, will cause invisible damage and produce hidden danger, therefore 20 crab-bolts are made the average load tensile test tunnel segment structure:

Account form: 633kg * 15=9495kg, 9495kg ÷ 20=474.75kg

Single crab-bolt average load tensile test value is 474.75kg.

Single crab-bolt average load pulling force 474.75kg can be directly as the test pulling force, adopt the tautness meter scale to do measurement, wait the chemical anchor bolts plantation fully to solidify after, the single crab-bolt of random selection is carried out tensile test.

Tautness meter scale 3 has been installed in this method of testing, and described tautness meter scale 3 catches on fixed body 4, by tightening up chain block 2, observes the reading of tautness meter scale 3, progressively make and test the setting that pulling force reaches load test, and stop is no less than 10min.

Embodiment 2

As shown in Figure 1, a kind of test of hoisting machinery load, described test are static test.Because preparing the factory building majority of examination hoisting machinery is newly to construct the factory buildings, the scene is not easy to prepare the load counterweight.And, then must prepare rated load, 1.25 times of load and 1.1 times of load according to examination requirements, the tonnage of the required load of other electrical category special equipments examinations is bigger relatively, and is difficult for lifting.

After finding fixed body 4 on the terrace, install pulling force scale 3, by tightening up chain block 2, be loaded on rated load gradually, carry out static rigidity and measure.This moment, just in time dolly was positioned at span centre, counted the downwarp value when the measurement dolly is positioned at span centre from actual arch value.Be loaded on 1.25 times rated load by tightening up chain block then, stop is no less than 10min.Reexamine the permanent strain situation after the unloading, repeat 3 times.

Claims (2)

1. lift heavy load test device, comprise by geodesic structure or device (1) and chain block (2), it is characterized in that: described chain block (2) is connected by the lower end of geodesic structure or device (1), tautness meter scale (3) is installed in the lower end of described chain block (2), fixed body (4) is caught on by drag hook in described tautness meter scale (3) lower end, and described fixed body (4) fixes on the ground.
2. a kind of lift heavy load test device according to claim 1 is characterized in that: described is big mini-plant suspension hook or pipe-hanging hook or hoisting machinery by geodesic structure or device (1).
