Adjustable support device and lift car

Abstract

The invention discloses an adjustable supporting device and a lift car equipped with the same. The adjustable supporting device is installed on a base plate of the lift car and is used for supportinga lifting platform of the lift car; the adjustable supporting device comprises a sleeve, a supporting rod and a locking unit; one end of the sleeve is fixed to the base plate; the inner wall of the sleeve is provided with an internal thread; the wall of the sleeve is provided with an axial open groove; the supporting rod is arranged inside the sleeve in a sleeving manner; the outer wall of the supporting rod is provided with an external thread which is matched with the internal thread; the end, far away from the base plate, of the supporting rod protrudes out of the sleeve and is used for supporting the lifting platform; and the locking unit is arranged on the sleeve and is used for adjusting the width of the open groove so as to lock or loosen the sleeve. The adjustable supporting devicedisclosed by the invention can realize height adjustment of the supporting rod so as to flexibly adapt to the height of the lifting platform and can be used for supporting the lifting platform.

Description

technical field [0001] The present invention relates to the technical field of supporting devices, in particular to an adjustable supporting device and a lifting vehicle equipped with the adjustable supporting device. Background technique [0002] The lifting platform and the fork frame of the lift truck are connected by a bushing, and the relative position changes during the lifting process are realized by the rollers walking in the guide rail. When the lifting platform falls to the lowest position, the bottom surface of the guide rail of the lifting platform and the four platforms on the chassis The brace fits perfectly. [0003] At present, the platform support of the lift truck adopts a support frame structure with a fixed height. The support frame is fixed on the chassis girder, and the lifting platform is installed on the fork frame. The upper surface of the support frame is close, but in the actual production process, it is found that there are many factors that affe...

AI Technical Summary

Problems solved by technology

[0003] At present, the platform support of the lift truck adopts a support frame structure with a fixed height. The support frame is fixed on the chassis girder, and the lifting platform is installed on the fork frame. The upper surface of the support frame is close, but in the actual production process, it is found that there are many factors that affect the height of the lowest position of the lifting platform, such as the error value of the production and processing of the fork frame and the support frame, the lower limit switch of the fork frame, and the weight of the carriage. The deformation of the front and rear axle leaf springs of the chassis causes the lowest position of the lifting platform of each car to be not a fixed value, and even the height of the front and rear ends of the lifting platform of the same car is not easy to determine, so the platform support frame is all on-site. There will be four support frames of the same car with four different heights and sizes. It is difficult to ensure product consistency and cannot be mass-produced in advance, which will bring great trouble to design, production and after-sales service
