Problems solved by technology
Since the rising height of the mast can reach more than 6 meters, it is difficult to adjust the position
Therefore, it is difficult for the laser rangefinder to measure multiple parameters such as the front, rear, left, and right tilt of the forklift mast.
) Among them, there is no advanced method to measure the natural slide of the forklift fork, and the accuracy is not high

Embodiment Construction
[0024] The present invention will be further described below in conjunction with the drawings and embodiments.
[0025] Such as figure 1 As shown, the present invention includes the following parts:
[0026] 1) CCD image acquisition system: it is composed of a PC, an image acquisition CCD, an image acquisition card, a long focal length lens 28 and a short focal length lens 27. The long focal length lens 28 and the short focal length lens 27 are respectively connected to the image acquisition CCD, the image acquisition card is connected with the CCD, and the image acquisition card is inserted into the PC.
[0027] 2) Two-dimensional rotating platform: It consists of an angle encoder, two-dimensional rotating frame and driving motor. The long focal length lens and the short focal length lens are installed on a two-dimensional turret, and the two-dimensional turret is driven by a drive motor to rotate in two dimensions to track the target LED through lens imaging, and an angle encoder ...

The invention discloses a system for automatically measuring the natural glissade quantity of a pallet fork on a forkman, comprising a CCD image acquisition system, a two-dimensional rotating platform, a target LED and a hydraulic system. The CCD image acquisition system consists of a PC, an image acquisition CCD, an image capture card, a long-focal lens and a short-focus lens; the two-dimensional rotating platform consists of an angle encoder, a two-dimensional rotating bracket and a driving motor; the long-focal lens and the short-focus lens are installed on the two-dimensional rotating bracket which is driven to rotate by the driving motor, the target LED is traced by lens imaging, and the angle encoder is arranged on a rotation axis for recording the angle; the pallet fork on the forkman is installed on an experimental bench of the pallet fork, and then the target LED is fixed on the wall of the pallet fork on the forkman; the hydraulic system is used for replacing a power system of the forkman to supply the power. The image of the natural glissade quantity formed by the long-focal lens is obtained by the accurate detection of image processing software. The measuring precision of the natural glissade quantity of the pallet fork on the forkman is caused to exceed the order of magnitude required by the current market precision.
Description
Technical field [0001] The invention relates to an automatic measuring system, in particular to an automatic measuring system for the natural sliding amount of the fork of a forklift. Background technique [0002] At present, the proportion of logistics costs in my country's society as a percentage of GDP has been hovering around 21.3% for seven consecutive years, while the level of foreign logistics in developed countries is about 10%. The domestic logistics industry is still in a stage of rapid development. As an important tool for logistics, the popularization of forklifts will greatly reduce the logistics costs of enterprises. Facing this huge market segment, all advanced forklift brands in the world have entered the Chinese market in various forms. China's local forklift engineering machinery factories should improve the quality of their products to occupy the Chinese market. (Hangzhou Forklift Engineering Machinery Co., Ltd. is one of the backbone enterprises in the dome...
