A kind of hydraulic elevating platform with guiding device
Technical field
The present invention relates to a kind of hydraulic elevating platform, be specifically related to a kind of hydraulic elevating platform with guiding device showing height and angle.
Background technique
When microwave dark room is tested, need to place test instrument in the place of ten meters, distance microwave darkroom loudspeaker, the supporting surface placing the platform of test instrument needs the height on distance ground at 1.3-1.7m, supporting surface rotates between ± 60 °, and the angle that the height of supporting surface and supporting surface turn over will be shown, existing standard raising platform does not meet above requirement, and the table top of raising platform is 360 ° of rotations, and highly do not show, highly regulate size also undesirable.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of hydraulic elevating platform with guiding device, height and the angle turned over of display table top that can be real-time, and after table top is fixing, undertaken spacing by stop screw, reliable operation, cost is low.
Technological scheme: for solving the problems of the technologies described above, a kind of hydraulic elevating platform with guiding device of the present invention, comprise base, be positioned at the hydraulic pressure installation on base, the hydraulic rod be connected with hydraulic pressure installation, the table top being placed on the lifting bar inside hydraulic rod and being connected with lifting bar, described table top is connected with the top of lifting bar by mounting plate, on mounting plate, symmetry is provided with position-limited lever, the top of hydraulic rod is provided with guiding device, guiding device comprises the first guide plate and the second guide plate, first guide plate is provided with arc groove, second guide plate is provided with the arc groove identical with the first guide plate angle, position-limited lever is through arc groove, the afterbody of position-limited lever is provided with stop screw.
As preferably, the angle of described arc groove is 120 °, and the angle index that the first guide plate and the second guide plate are provided with hydraulic rod axis is the center of circle, position-limited lever is provided with altitude scale.
As preferably, the afterbody of described stop screw is provided with block rubber.
As preferably, the side of described table top is provided with handle.
Beneficial effect: a kind of hydraulic elevating platform with guiding device of the present invention, rotated in arc groove by position-limited lever, ensure that table top rotates between ± 60 °, height and the angle turned over of display table top that can be real-time, and after table top is fixing, undertaken spacing by stop screw, reliable operation, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of hydraulic elevating platform with guiding device of the present invention, comprise base 1, be positioned at the hydraulic pressure installation on base 1, the hydraulic rod 2 be connected with hydraulic pressure installation, the table top 6 being placed on the lifting bar 7 inside hydraulic rod 2 and being connected with lifting bar 7, table top 6 is connected by the top of mounting plate with lifting bar 7, on mounting plate, symmetry is provided with mounting hole, one end of position-limited lever 5 is inserted in mounting hole, pass through screw lock, the top of hydraulic rod 2 is provided with guiding device, guiding device comprises the first guide plate 4 and the second guide plate 8, first guide plate 4 and the second guide plate 8 are respectively the plate of semicircular arc, first guide plate 4 is provided with arc groove, second guide plate 8 is provided with the arc groove identical with the first guide plate 4 angle, arc groove internal diameter 2mm more about than the diameter of hydraulic rod 2, position-limited lever 5 is through arc groove, position-limited lever 5 moves freely in arc groove, the afterbody of position-limited lever 5 is provided with stop screw 3.
In the present invention, the angle of arc groove is 120 °, the angle index that first guide plate 4 and the second guide plate 8 are provided with hydraulic rod 2 axis is the center of circle, position-limited lever 5 is provided with altitude scale, the height of convenient display table top 6 and the angle turned over, the afterbody of stop screw 3 is provided with block rubber, facilitates stop screw 3 to prop up hydraulic rod 2, the side of table top 6 is provided with handle, facilitates rotation work table top 6.
In use, testing apparatus is placed on table top 6, experimentally requirement in the present invention, press hydraulic pressure installation, according to the height display on position-limited lever 5, table top 6 is adjusted to suitable height, by handle rotation work table top 6, according to the angle display on the first guide plate 4, table top 6 is adjusted to suitable angle, tightens stop screw 3, make stop screw 3 withstand hydraulic rod 2, fixing position-limited lever 5, thus steady job table top 6.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
