Fig. 3 is the using state schematic diagram of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1 and Figure 2, the preferred embodiment of the present invention comprises base 1, column 2, reading sliding shoe 3, chi frame 5.
Specifically, more as shown in Figure 3, base 1 for being placed on the bottom web of hot rolling J type forklift door frame channel-section steel 8, to provide measuring basis.Preferably, base 1 is in block, and such as rectangular shape, has smooth bottom surface, so that be flatly placed in channel-section steel 8.
The lower end of column 2 is fixed on base 1 by modes such as welding, securing member connection or clampings.Preferably, the platy structure that column 2 is elongated, in the side of column 2, is provided with scale mark along its length direction.Further, two vertical edges of column 2 side are equipped with scale mark so that observe, reading.
Reading sliding shoe 3 is used in reference to the scale mark on column 2, is two, is arranged on the both sides of column 2 symmetrically, and reading sliding shoe 3 is slidably disposed on column 2.Preferably on reading sliding shoe 3, also scale mark is set, like this can pin-point reading to 0.1mm, on column 2, reading is to 1mm.Specifically, first correct during measuring height, survey instrument is placed on horizontal stand and carries out reading, as in Figure of description 1, when on design column 2, reading is zero, on the lower plane of movable jaw 6 and base 1 plane be same plane (herein the upper plane of base 1 refer to as shown in Figure 1 base 1 above plane, because survey instrument have rotated 180 degree in fig. 3, above the lower plane of movable jaw 6 is presented in fig. 3, below the upper plane of base 1 is presented in figure 3), after there are gap or wearing and tearing after service time is long, horizontal stand is measured, the numerical value read is non-vanishing, the numerical value now read is zero error), when measuring object height, first the integer numerical value of display on column 2 is read, unit is millimeter, then see on sliding shoe 3, which bar scale mark aligns with the scale mark on column 2, if there is no perfectly aligned line, the line then got closest to alignment carries out reading, such as, on column 2, integer is 54mm, on sliding shoe 3 aligns with the scale mark on column 2 is 3, be then 0.3mm, deduct the zero error of reading again, then reading result is the fraction part-zero error on integral part+sliding shoe 3 on h=column 2, i.e. h=54mm+0.3mm-zero error.Preferably, as shown in Figure 1, reading sliding shoe 3 is similar to bar blocks, reading sliding shoe 3 is provided with chute (as Fig. 2, unmarked), the both sides of the edge of column 2 are provided with boss (as Fig. 2, unmarked), boss embeds in chute, and reading sliding shoe 3 freely up and down can be slided along column 2; In other examples, also boss can be located on reading sliding shoe 3, chute be located at column 2, boss embeds in chute, and realizing reading sliding shoe 3 freely up and down can slide along column 2.In order to can reading sliding shoe 3 be fixed on column 2 when needed, the bolt 31 crossed is provided with in reading sliding shoe 3, bolt 31 is through reading sliding shoe 3, can support on column 2 (boss), during clamping screw 31, then reading sliding shoe 3 can be fixed on column 2 (boss), be convenient to pin-point reading.
Chi frame 5 is two, with two reading sliding shoe 3 one_to_one corresponding, upper end is individually fixed in a reading sliding shoe 3, and lower end can be set to the flat surfaces of level, for supporting on two leg end faces of hot rolling J type forklift door frame channel-section steel 8 (as Fig. 3) respectively.And in the preferred embodiment, the lower end of chi frame 5 is provided with adjustable movable jaw 6, movable jaw 6 is provided with for supporting the flat surfaces on two leg end faces of hot rolling J type forklift door frame channel-section steel 8.Web member by comprising bolt 51 between chi frame 5 and movable jaw 6 connects, and so, conveniently finely tunes movable jaw 6 position.
Further, chi frame 5 is the rod-like structure tilted laterally from reading sliding shoe 3, and the width of chi frame 5 will ensure that both sides movable jaw 6 all can be placed on two legs break faces of J type gantry channel-steel 8.
In the preferred embodiment, the upper end of 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, this screw rod 42 is through fine motion frame 4, nut 43 is provided with in the middle part of fine motion frame 4, screw rod 42 is also through nut 43, by rotating nut 43, screw rod 42 realizes moving up and down along column 2, the change of spacing between fine motion frame 4 and sliding shoe 3, and then promotes the up and down minute movement of sliding shoe 3 along column 2.The effect of fine motion frame 4 is, when measuring the softer or yielding object of material, when blocking object soon, first clamping screw 41, rotates the nut 43 on fine motion frame 4, realizes the slow movement of sliding shoe 3 and chi frame 5, and then movable jaw 6 blocks testee just, realize accurately measuring.If do not undertaken finely tuning by fine motion frame 4, likely to make movable jaw 6 block the pressure of object excessive and make deformation of body, causes measuring inaccurate, even damage testee.
In order to stop fine motion frame 4, reading sliding shoe 3 etc. from landing column 2 and boss thereof, the upper end of the column 2 of this preferred embodiment is provided with fixed cover 7, fixed cover 7 protrudes from column 2 surface, and reading sliding shoe 3 can be stoped from landing column 2 (boss).
As shown in Figure 3, when applying the lower leg height of this preferred embodiment measurement channel-section steel 8, base 1 is positioned on J type forklift door frame channel-section steel 8 bottom web, two movable jaw 6 ends contact two leg end faces of J type forklift door frame channel-section steel 8 respectively, after the bolt 51 of fixed ruler frame 5, reading can be carried out, height h1 and h2 of two lower legs of J type forklift door frame channel-section steel 8 can be read respectively, fraction part numerical value-zero error on integral part numerical value+sliding shoe 3 on height h1=column 2, fraction part numerical value-zero error on integral part numerical value+sliding shoe 3 on height h2=column 2, just two lower leg difference in height △ h=h1-h2 can be calculated subsequently.
To sum up, the present invention can measure two lower leg height of J type forklift door frame channel-section steel simultaneously, and then calculate the difference in height of two lower legs, reduce measuring error, and then avoid causing economic loss owing to unacceptable product being mistaken for certified products or certified products being mistaken for unacceptable product; The present invention can measure two lower leg height of J type forklift door frame channel-section steel simultaneously, improves measurement efficiency.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
