Description
Technical field
The invention belongs to pressure measurement technology field, be specifically related to a kind of spring catch force measuring machine quickly detecting ground intensity utilizing electric cylinder or hydraulic cylinder to produce motive force.
Background technology
Part special vehicle, when operation, needs a stable operating platform, determines that the most whether operating platform is that the landing stiffness of four supporting mechanisms of vehicle is enough.If landing stiffness is too soft, when within the activity duration, sedimentation value exceedes specified value, operating platform basic data misalignment or instability, affect homework precision and result, the attitude now adjusting vehicle takes long enough, affect working performance, if the run-off the straight in lifting process of lifting vehicle, have the danger of car crash.
Current existing ground intensity testing agency separatory pressure type and Wedged, both mechanisms overall dimensions is relatively big, and cost is high, and the detection time is longer, and after detection, defective needs again reorientates detection, wastes time.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned weak point and provides one to utilize spring catch quickly to detect the most satisfactory device for measuring force of ground intensity, can judge rapidly whether ground intensity meets requirement within the 3-5 second, if meeting, then supporting mechanism works on；If being unsatisfactory for, supporting mechanism interruption of work, select guard station else.
The technical solution of the present invention is: a kind of spring catch force measuring machine for quickly detecting ground intensity, it is characterised in that: include spherical bearing, pressure transducer, compression spring, guide pillar plate, a support plate, dynamometry pin and dynamometry pin cap plate；Described spherical bearing is fixed together with a support plate；Described pressure transducer is fixed in the bottom groove of spherical bearing, and pressure spot is down；With pressure transducer just to support plate be provided with installation through hole, dynamometry pin cap plate is arranged on this installation through hole outer end；Dynamometry pin is the tubular construction of lower end closed, and upper end is provided with convex edge radially, and the tubular construction of dynamometry pin lower end closed passes dynamometry pin cap plate；Compression spring upper end is sleeved on guide pillar plate, and lower end is positioned at dynamometry pin tubular construction；Guide pillar plate upper end is provided with the plane corresponding with pressure transducer pressure spot.
On dynamometry pin cap plate described in the technical solution of the present invention, the contact surface with dynamometry pin is provided with dust ring, prevents dust from entering inside dynamometry pin.
Spherical bearing described in the technical solution of the present invention and the contact surface between a support plate are spherical.
Dynamometry pin cap plate described in the technical solution of the present invention is fixed together with a support plate by screw, makes compression spring produce an initial precompression.
Due to the fact that and use the spring catch force measuring machine being made up of spherical bearing, pressure transducer, compression spring, guide pillar plate, a support plate, dynamometry pin and dynamometry pin cap plate, it is arranged on electric cylinder or the device front end of hydraulic cylinder composition detection ground intensity, thus the contact jaw plane of guide pillar plate is close to the impetus of sensor under the action of the spring, normal pressure suffered by dynamometry pin passes to pressure transducer by compression spring, according to the power of feedback and the diameter of dynamometry pin, control part show that ground intensity value, whole process have only to several seconds.The present invention have can improve special vehicle operation work efficiency, can improve that functional reliability, size be little, simple in construction and the quick feature of detection.Present invention is mainly used for ground bearing strength is used for quickly detecting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the upward view of Fig. 1.
In figure: 1-spherical bearing, 2-pressure transducer, 3-guide pillar plate, 4-props up support plate, 5-screw, 6-compression spring, 7-dynamometry pin, 8-dust ring, 9-dynamometry pin cap plate.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2.The present invention includes spherical bearing 1, pressure transducer 2, compression spring 6, guide pillar plate 3, a support plate 4, dynamometry pin 7 and dynamometry pin cap plate 9 for the spring catch force measuring machine of quickly detection ground intensity.Spherical bearing 1 profile is spherical, and support plate 4 top is provided with ball recess, and the contact surface between spherical bearing 1 and a support plate 4 is spherical, and spherical bearing 1 is together with propping up a support plate 4 and being fixed by screws in.Pressure transducer 2 is fixed in the bottom groove of spherical bearing 1, and pressure spot is down.On support plate 4 with pressure transducer 2 just to position be provided with through installation through hole, dynamometry pin cap plate 9 is fixed on a support plate 4 of this installation through hole outer end by screw 5, makes compression spring 6 produce an initial precompression.Compression spring 6 is vertically placed in installation through hole, and upper end is sleeved on guide pillar plate 3, and compression spring 6 play the guiding role when compressing, and lower end is positioned at dynamometry pin 7.Guide pillar plate upper end is provided with the plane corresponding with pressure spot, in order to more preferably contact with the impetus of pressure transducer 2.Dynamometry pin 7 is the tubular construction of lower end closed, and dynamometry pin 7 is through dynamometry pin cap plate 9, and upper end is provided with convex edge radially, the extension elongation of limiting measuring force pin 7.On dynamometry pin cap plate 9, the contact surface with dynamometry pin 7 is provided with dust ring 8, prevents dust from entering inside dynamometry pin.
Operation principle is as follows:
(electric cylinder or hydraulic cylinder) bulb bearing 1 moves to next, first dynamometry pin 7 bottom surface contacts ground, ground produces a counteracting force in the face of dynamometry pin 7, if this counteracting force is less than compression spring 6 initial pressure, dynamometry pin 7 extension elongation is constant, continues to move (now may determine that ground intensity is undesirable) along with (electric cylinder or hydraulic cylinder) bulb bearing 1 to next；If this counteracting force is more than compression spring 6 initial pressure, compression spring 6 is compressed, and dynamometry pin 7 moves；Along with spherical bearing 1 constantly moves down, compression spring 6 is compressed into dynamometry pin and is fully retracted, and dynamometry pin 7 bottom surface is concordant with dynamometry pin cap plate 9.
During this, control system draws ground intensity value according to power change, compression spring 6 decrement and dynamometry pin areal calculation.
