Background technology
Part special vehicle, when operation, needs a stable operating platform, determines the most whether operating platform is car
The landing stiffness of four supporting mechanisms is enough.If landing stiffness is too soft, within the activity duration, sedimentation value exceedes specified value
Time, operating platform basic data misalignment or instability, affect homework precision and result, the attitude now adjusting vehicle needs the longest
Time, 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, becomes
This height, the detection time is longer, and after detection, defective needs again reorientates detection, wastes time.
Summary of the invention
The purpose of this utility model is aiming at above-mentioned weak point and provides one to utilize spring catch quickly to detect ground
The most satisfactory device for measuring force of intensity, can judge whether ground intensity meets requirement rapidly 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.
Technical solution of the present utility model is: a kind of spring catch force measuring machine for quickly detecting ground intensity,
It is characterized 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, pressurized
Point 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 is through surveying
Power 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 be provided with
The plane that pressure transducer pressure spot is corresponding.
It is provided with anti-with the contact surface of dynamometry pin on dynamometry pin cap plate described in technical solution of the present utility model
Konisphere, prevents dust from entering inside dynamometry pin.
Spherical bearing described in technical solution of the present utility model and the contact surface between a support plate are spherical.
Dynamometry pin cap plate described in technical solution of the present utility model is fixed together with a support plate by screw,
Compression spring is made to produce an initial precompression.
This utility model is owing to using by spherical bearing, pressure transducer, compression spring, guide pillar plate, support plate, dynamometry pin
The spring catch force measuring machine constituted with dynamometry pin cap plate, before being arranged on the device of electric cylinder or hydraulic cylinder composition detection ground intensity
End, thus the contact jaw plane of guide pillar plate is close to the impetus of sensor under the action of the spring, the normal pressure suffered by dynamometry pin is led to
Excess pressure spring passes to pressure transducer, and control part draws ground intensity value according to the power of feedback and the diameter of dynamometry pin,
Whole process has only to several seconds.This utility model has can improve the work efficiency of special vehicle operation, can improve work can
Little, simple in construction and the quick feature of detection by property, size.This utility model is mainly used in carrying out ground bearing strength quickly
Detection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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, and 7-surveys
Power pin, 8-dust ring, 9-dynamometry pin cap plate.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2.This utility model includes spherical for the spring catch force measuring machine of quickly detection ground intensity
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.Outside spherical bearing 1
Shape 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, spherical
Together with bearing 1 is fixed by screws in a support plate 4.Pressure transducer 2 is fixed in the bottom groove of spherical bearing 1, pressurized
Point 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 passes through screw
5 are fixed on a support plate 4 of this installation through hole outer end, make compression spring 6 produce an initial precompression.Compression spring 6 is vertical
Being placed in installation through hole, 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
In 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, limiting measuring force pin 7
Extension elongation.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, and first dynamometry pin 7 bottom surface contacts ground, and ground is in the face of surveying
Power pin 7 produces a counteracting force, if this counteracting force is less than compression spring 6 initial pressure, dynamometry pin 7 extension elongation is constant, continues
Continue along with (electric cylinder or hydraulic cylinder) bulb bearing 1 moves (now may determine that ground intensity is undesirable) to next；Should
If 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 is continuous
Moving 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 according to power change, compression spring 6 decrement and dynamometry pin areal calculation
Intensity level.
