Hydraulic elevating platform provided with guide device

Abstract

The invention discloses a hydraulic elevating platform provided with a guide device. The hydraulic elevating platform comprises a base, a hydraulic device positioned on the base, a hydraulic rod connected with the hydraulic device, an elevating rod arranged inside the hydraulic rod in a sleeving manner, and a work surface connected with the elevating rod, wherein the work surface is connected with the top end of the elevating rod through a mounting plate; limiting rods are symmetrically arranged on the mounting plate; the guide device is arranged on the upper part of the hydraulic rod; the guide device comprises a first guide plate and a second guide plate; the first guide plate is provided with a circular-arc groove; the second guide plate is provided with a circular-arc groove having the same angle as the first guide plate; the limiting rod passes through the circular-arc grooves; a limiting screw is arranged on the tail part of the limiting rod. According to the hydraulic elevating platform provided with the guide device disclosed by the invention, the work surface rotates within the range of + / -60 degrees through the rotation of the limiting rod in the circular-arc grooves, and the height and rotation angel of the work surface can be displayed in real time; moreover, after the work surface is fixed, the work surface is limited through the limiting screw, so that the hydraulic elevating platform works reliably, and is low in cost.

Description

technical field [0001] The invention relates to a hydraulic lifting platform, in particular to a hydraulic lifting platform with a guide device capable of displaying height and angle. Background technique [0002] When testing in the microwave anechoic chamber, it is necessary to place the test instrument ten meters away from the horn of the microwave anechoic chamber. The support surface of the platform on which the test instrument is placed needs to be 1.3-1.7m above the ground, and the support surface should be rotated between ±60°. And to display the height of the support surface and the angle at which the support surface turns, the existing standard lifting platform does not meet the above requirements. The work surface of the lifting platform rotates at 360 °, and there is no height display, and the height adjustment size does not meet the requirements. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art...

Problems solved by technology

[0002] When conducting tests in the microwave anechoic chamber, it is necessary to place the test instrument at a distance of ten meters from the speaker in the microwave anechoic chamber. 1.3-1.7m, the support surface rotates between ±60°, and the height of the support surface and the angle of the support surface should be displayed. The existing standard lifting platform does not meet the above requirements, and the working table of the lifting platform rotates at 360° , and there is no height display, and the height adjustment size does not meet the requirements
