Detailed description of the invention
Fig. 1 is the schematic view of the front view of the preferred embodiment of the present invention；
Fig. 2 is the overlooking structure diagram of the preferred embodiment of the present invention；
Fig. 3 is the use state diagram of the preferred embodiment of the present invention.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figure 1 and Figure 2, the preferred embodiment of the present invention includes pedestal 1, column 2, reading sliding shoe 3, ruler frame 5.
Specifically, again as shown in figure 3, pedestal 1 is used to be placed on the bottom web of hot rolling J-type forklift door frame channel steel 8, with
Measuring basis is provided.Preferably, pedestal 1 has flat bottom surface, in bulk, such as rectangular shape in order to horizontally
It is placed in channel steel 8.
The lower end of column 2 is connected by welding, fastener or the modes such as clamping are fixed on pedestal 1.Preferably, column
2 elongated plate structures are provided with graduation mark along its length direction in the side of column 2.Further, 2 side of column
Two vertical edges in face are equipped with graduation mark, in order to observe, read.
The graduation mark that reading sliding shoe 3 is used to be directed toward on column 2 is two, is symmetrically disposed in the two sides of column 2, and
Reading sliding shoe 3 is slidably disposed on column 2.It preferably is also provided with graduation mark on reading sliding shoe 3, it in this way can be with
Pin-point reading is to 0.1mm, and reading is to 1mm on column 2.Specifically, it is first corrected when measuring height, measuring tool is placed
It is read on horizontal platform, in Figure of description 1, when reading is zero on design column 2, the lower plane and pedestal 1 of movable jaw 6
Upper plane be same plane (the upper plane of pedestal 1 refers to the plane of the upper surface of pedestal 1 as shown in Fig. 1 herein, because
Measuring tool has rotated 180 degree in attached drawing 3, and the lower plane of movable jaw 6 is shown in above in fig. 3, and the upper plane of pedestal 1 is being schemed
It is shown in 3 following), after occurring gap or abrasion after a long time, measured on horizontal platform, the numerical value of reading is not zero,
The numerical value read at this time is zero error), when measuring object height, the integer numerical value shown on column 2 is first read out, unit is milli
Rice, then sees which graduation mark is aligned with the graduation mark on column 2 on sliding shoe 3, if taking most without perfectly aligned line
Line close to alignment is read, for example, integer is 54mm on column 2, is aligned on sliding shoe 3 with the graduation mark on column 2
Be 3, then be 0.3mm, then subtract the zero error of reading, then read result be h=column 2 on integer part+sliding shoe 3 on
Fractional part-zero error, i.e. h=54mm+0.3mm- zero error.Preferably, as shown in Figure 1, reading sliding shoe 3 is similar to item
Shape block, reading sliding shoe 3 are equipped with sliding slot (such as Fig. 2, unmarked), and the both sides of the edge of column 2 are equipped with boss, and (such as Fig. 2 is not marked
Note), boss is embedded in sliding slot, and reading sliding shoe 3 is freely up and down slided along column 2；In other examples,
Boss can also be located on reading sliding shoe 3, sliding slot is located at column 2, boss is embedded in sliding slot, realizes reading sliding shoe 3
It can freely up and down be slided along column 2.It is fixed on column 2 when needed in order to which sliding shoe 3 will be read, reading sliding
The bolt 31 crossed is provided in block 3, bolt 31 passes through reading sliding shoe 3, can support on column 2 (boss), clamping screw
When 31, then reading sliding shoe 3 can be fixed on column 2 (boss), be convenient for pin-point reading.
Ruler frame 5 is two, is corresponded with two reading sliding shoes 3, and upper end is individually fixed in a reading sliding shoe 3, under
End can be set to horizontal flat surfaces, for being supported respectively in two leg end faces of hot rolling J-type forklift door frame channel steel 8
(such as Fig. 3).And in the preferred embodiment, the lower end of ruler frame 5 is provided with adjustable movable jaw 6, and movable jaw 6 is provided with for supporting in heat
Roll the flat surfaces on two leg end faces of J-type forklift door frame channel steel 8.By including bolt 51 between ruler frame 5 and movable jaw 6
Connector connection, in this way, convenient be finely adjusted 6 position of movable jaw.
Further, ruler frame 5 is that inclined rod-like structure, the width of ruler frame 5 will guarantee two outward from reading sliding shoe 3
Side movable jaw 6 can be placed on two legs break faces of J-type gantry channel-steel 8.
In the preferred embodiment, the upper end for reading sliding shoe 3 is connected with fine motion frame 4, with more convenient, more pin-point reading.
The upper end of sliding shoe 3 is connected with screw rod 42, which passes through fine motion frame 4, is equipped with nut in the middle part of fine motion frame 4
43, screw rod 42 also passes through nut 43, and by rotating nuts 43, screw rod 42 realizes moving up and down along column 2, fine motion frame 4 and cunning
The variation of spacing between motion block 3, and then push sliding shoe 3 along the minute movement up and down of column 2.The effect of fine motion frame 4 is to survey
Amount is when the material is soft or easily-deformable object, and when blocking object fastly, first clamping screw 41 rotates the nut 43 on fine motion frame 4,
Realize the slow movement of sliding shoe 3 and ruler frame 5, and then movable jaw 6 blocks testee just, realization accurately measures.If obstructed
It crosses fine motion frame 4 to be finely adjusted there is a possibility that the pressure of blocking object of movable jaw 6 is excessive and deform object, causes measurement inaccurate, very
To damage testee.
In order to prevent fine motion frame 4, reading sliding shoe 3 etc. from sliding from column 2 and its boss, the column of this preferred embodiment
2 upper end is equipped with fixing sleeve 7, and fixing sleeve 7 protrudes from 2 surface of column, can prevent reading sliding shoe 3 from column 2 (boss)
It slides.
As shown in figure 3, pedestal 1 is placed in J-type fork truck door when the lower leg using this preferred embodiment measurement channel steel 8 is high
On 8 bottom web of rack slot steel, two 6 ends of movable jaw contact two leg end faces of J-type forklift door frame channel steel 8 respectively, fixed ruler frame 5
It after bolt 51, can be read, the height h1 and h2 of two lower legs of J-type forklift door frame channel steel 8, height h1 can be read respectively
Fractional part numerical value-zero error on integer part numerical value+sliding shoe 3 on=column 2, the integer on height h2=column 2
Fractional part numerical value-zero error on component values+sliding shoe 3 can then calculate two lower leg difference in height △ h=
h1-h2。
To sum up, the present invention can measure two lower leg height of J-type forklift door frame channel steel simultaneously, and then calculate under two
The difference in height of leg reduces measurement error, and then avoids since rejected product is mistaken for qualified product or being mistaken for qualified product
Rejected product causes economic loss；The present invention can measure two lower leg height of J-type forklift door frame channel steel simultaneously, improve survey
Amount efficiency.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute
Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
