Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of chock load test device, is made up of main load maintainer, auxiliary fixing fastening mechanism.
Main load maintainer mainly comprises stand 1, main hydraulic cylinder 2, tautness meter 3.Auxiliary fixing fastening mechanism mainly comprises fixing shackle 4, circular hoisting belt 5, and the linked hydraulic mechanism to be made up of pitching hydraulic cylinder 6, positioning hydraulic cylinders 7, guide rail 8, activity shackle 9, latch 10, wherein positioning hydraulic cylinders 7 comprises orienting sleeve 11 and hydraulic stem 12.
Stand 1 is firm framed structure, and main hydraulic cylinder 2 is arranged on above stand 1 and fixes with bolt, and tautness meter 3 is arranged on below main hydraulic cylinder 2, and chock 13 to be tested is arranged on below tautness meter 3.Pitching hydraulic cylinder 6, guide rail 8 are hinged on same pillar below stand 1 in upper-lower position respectively, and it is hinged between the two, orienting sleeve 11 is sleeved on guide rail 8, hydraulic stem 12 one end is hinged on pillar at guide rail 8 afterbody, the other end and orienting sleeve 11 hinged, activity shackle 9 is fixed on orienting sleeve 11, and latch 10 to be arranged on stand 1 and to be positioned at below guide rail 8.Fixing shackle 4 is arranged on below another root pillar.Circular hoisting belt 5 is through the lifting hole(eyelet) 14 on chock 13 to be tested, and two ends connect respectively by fixing shackle 4, activity shackle 9, and chock 13 setting fastening is fixed thus can be born test pressure by circular hoisting belt 5.
In the utility model, all working hydraulic cylinder has driven required action by the hydraulic oil that an external hydraulic power unit provides, and requires to set pressure according to required acting force, and is provided with pressurized overflow protection and prevents overload.
Main load maintainer principle of work: upper and lower expanding-contracting action after main hydraulic cylinder 2 connects hydraulic oil, tautness meter 3 pairs of chocks 13 are driven to apply required test pulling force, after chock 13 is thus lifted to certain altitude, due to its by circular hoisting belt 5 constrain in cannot to continue bottom stand 1 mobile, now interaction force can be produced between chock 13 and circular hoisting belt 5, complete test load applying, simultaneously because circular hoisting belt 5 length is in advance through calculating fixed length, so when chock 13 is in stressed tensioning state, circular hoisting belt 5 tensioning on chock 13 forms 45 ° of contact angles of test request, as shown in Figure 2.
Auxiliary fixing fastening mechanical work principle: pitching hydraulic cylinder 6, positioning hydraulic cylinders 7, guide rail 8 all can swing up and down around its pin joint separately, pitching hydraulic cylinder 6 expanding-contracting action under hydraulic oil effect drives guide rail 8 to swing up and down, positioning hydraulic cylinders 7 does straight reciprocating motion according to the swing of guide rail 8 along it, thus driving activity shackle 9 does straight reciprocating motion along guide rail 8, realize the tensioning of circular hoisting belt 5 thus and relax, activity shackle 9 is fixed so that the circular hoisting belt 5 through chock 13 is drawn to latch 10 place by latch 10, make circular hoisting belt 5 be in tensioning state and be convenient to next step loading, and be convenient to take out circular hoisting belt 5 from chock 13 when relaxed state and remove the chock be completed, next test block can be installed.
When adopting the utility model chock load test device to start to test, tested workpiece chock is hung in rack base, control main hydraulic cylinder decline to stretch out, tautness meter is made to aim at chock and use pinned connection, then lax circular hoisting belt is put into chock guide groove by chock lifting hole(eyelet), control pitching hydraulic cylinder and start action, drive guide rail to swing and guide rail position is adjusted to extreme lower position, signal can be provided by responding to spacing or travel switch after guide rail arrives minimum swing position, positioning hydraulic cylinders starts action after obtaining signal, dragging activity shackle is along guide rail to circular hoisting belt, circular hoisting belt one end setting fastening is unloaded in activity and buckles, and retraction is until latch place and activity shackle are fixed, larger test load reaction force can be born.
When test loads, main hydraulic cylinder starts retracting action, drives tautness meter that loading force is passed to chock simultaneously, chock is pulled and leaves rack base and start to move upward, chock is held onto by circular hoisting belt, and circular hoisting belt is also tensioned simultaneously, and chock completes load and loads.Because the acting force of pitching hydraulic cylinder and positioning hydraulic cylinders presets, ensured by the oil pressure relief arranging surplus valve setting on oil circuit, namely pitching cylinder force only meets the swing of driving guide rail, positioning hydraulic cylinders acting force only meets dragging activity and unloads that to be buckled in slide on rails pre-tensioner by circular hoisting belt, and test loading force much larger than these two acting forces, so when circular hoisting belt is pulled by main hydraulic cylinder to tighten more energetically, the surplus valve pressure release of pitching hydraulic cylinder and positioning hydraulic cylinders, at this moment passive action can regulate to adapt to the tensioning angle of circular hoisting belt voluntarily along with the tensioned state of circular hoisting belt after pitching hydraulic cylinder and positioning hydraulic cylinders exceed setting acting force, and be unlikely to suppress the state change of circular hoisting belt to produce extra reacting force, so auxiliary fixing fastening mechanism can design lightweight, 45 ° of contact angles of circular hoisting belt and chock also can ensure simultaneously.
The utility model utilizes main hydraulic cylinder to replace crane imposed load, reduces Large Copacity hoisting device holding time, eliminates the investment of high-stability ground or large-tonnage counterweight, saved production cost; Two small cylinders have coordinated the fixing of chock and stand, without the need to manual operation, only need non-productive operation electromagnetic valve switch, decrease human resources configuration; Loading in the load test step of chock and installation fixed work order are concentrated on a table apparatus and completes, simplify testing procedure; Because hydraulic cylinder is driven by hydraulic coupling, working pressure sets by hydraulic valve block, there will not be overflow situation, makes test job more safe and reliable; The 45 ° of contact angles formed with test hanging belt after chock is loaded, the more close stress form simulating the actual working state of chock, improves the effect of load test; Improve load test efficiency.
