Abstract
The utility model discloses a kind of novel industrial vehicle overhead guard dynamic test load, comprise load the first half, load impacting face (oak), lifting bolt, socket head cap screw, cylinder stopper.When carrying out dynamic test to the overhead guard of industrial vehicle, test load is risen to assigned address, release electromagnetism makes load free-falling, and whether vehicle impact overhead guard meets technical requirement to test overhead guard.It is stronger, fixed that the utility model industrial vehicle overhead guard dynamic test load has versatility, uses and the advantage such as easy to maintenance.
Description
Technical field
The utility model relate to a kind of novel industrial vehicle overhead guard dynamic test load.
Background technology
The technical requirement of industrial vehicle overhead guard and test method standard GB/T5143-2008 define the requirement of industrial vehicle overhead guard dynamic test load: test object should have the square shock surface that the length of side is 300mm, and its quality is 45kg.Shock surface should be made up of the material of oak or equal densities, and thickness is not less than 50mm.Corner angle and seamed edge should have the fillet of mm.Existing load is discharged by trip mechanism mostly, so not only waste of manpower, increases experimentation cost, and more dangerous, very easily forms potential safety hazard.
Utility model content
In order to solve the defect that prior art exists, the utility model discloses a kind of novel industrial vehicle overhead guard dynamic test load.
The technical solution adopted in the utility model is as follows:
A novel industrial vehicle overhead guard dynamic test load, comprise load the first half and load the latter half of being connected by coupling arrangement, a lifting bolt is respectively installed at the two ends, left and right of described load the first half.
Described load the first half adopts plain carbon steel material to make, during test, adsorbable on calutron, and when after release electromagnetism, load can free-falling.
Described load the latter half adopts oak material to make; As load impacting face.
Described load the first half, load the latter half are rectangular configuration.
Described coupling arrangement is socket head cap screw.
Described lifting bolt is connected with two ropes.
The bottom of described socket head cap screw is sealed by cylinder stopper.
When carrying out dynamic test to the overhead guard of industrial vehicle, test load is risen to assigned address, release electromagnetism makes load free-falling, and whether vehicle impact overhead guard meets technical requirement to test overhead guard.The shock surface of load and the first half use socket head cap screw to be connected and fixed, and when load impacting face is damaged, can pull down replacing rapidly.Lifting bolt is separately fixed at load the first half both sides, when carrying out impulse test can connecting rope to increase experimental safe.Load the first half uses plain carbon steel material, adsorbable on calutron.When after release electromagnetism, load can free-falling.
Compared to the prior art the utility model industrial vehicle overhead guard dynamic test load device, has following characteristics:
The utility model is adsorbable on calutron.By electromagnetic releasing, load free-falling can be made.Separately be aided with suspension ring to be flexible coupling and can to increase experimental safe, secondly load impacting face is once be damaged, and can change rapidly.So not only can meet the overhead guard dynamic test loading demands of national Specification, more improve efficiency and the security of test, reduce danger and the maintenance cost of test.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 (a)-(b) is the utility model the first half structural representation;
Fig. 3 (a)-(b) is the utility model the latter half structural representation;
Fig. 4 is the utility model using method schematic diagram;
1 load the first half in figure, 2, load the latter half, 3 lifting bolts, 4 socket head cap screws, 5 cylinder stoppers, 6 test loads, 7 ropes, 8 electromagnet, 9 vehicle overhead guards.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Embodiment 1
As shown in Figure 1, Figure 2 shown in (a)-Fig. 2 (b), Fig. 3 (a)-Fig. 3 (b), industrial vehicle overhead guard dynamic test load of the present utility model as shown in Figure 1, Figure 2 and Figure 3, comprises load the first half 1, load the latter half 2, lifting bolt 3, socket head cap screw 4, cylinder stopper 5.Load the latter half 2 i.e. shock surface is made by oak material, and physical dimension makes by the regulation of relevant criterion, and the material of load the first half 1 is plain carbon steel.Load the latter half 2 and load the first half 1 use socket head cap screw 4 to be connected and fixed.
Lifting bolt 3 is separately fixed at load the first half 1 both sides, when carrying out impulse test can connecting rope to increase experimental safe.
The shock surface of load and the first half use socket head cap screw to be connected and fixed, and when load impacting face is damaged, can pull down replacing rapidly.
Load the first half uses plain carbon steel material, adsorbable on calutron.When after release electromagnetism, load can free-falling.
When carrying out dynamic test to the overhead guard of industrial vehicle, test load is risen to assigned address, release electromagnetism makes load free-falling, and whether vehicle impact overhead guard meets technical requirement to test overhead guard, specifically as shown in Figure 4:
During test, load 6 be adsorbed on electromagnet 8, rope 7 connects lifting bolt 3 and the crossbeam at load two ends respectively, and rope 7 length is greater than load falling head.
Release electromagnetism, makes load freely falling body decline, vehicle impact overhead guard 9.
If load impacting face and load the latter half are damaged, socket head cap screw 4 can be unloaded and change rapidly.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
