Hydraulic lift truck for carrying armoring movable-type switch cabinet functional vehicles

Abstract

Disclosed is a hydraulic lift truck for carrying armoring movable-type switch cabinet functional vehicles. The problems that in the prior art, only the lifting height can be adjusted, the width cannot be adjusted, and a functional vehicle cannot be automatically locked on a hydraulic lift truck are solved. The hydraulic lift truck is characterized in that a nut is welded to a right vertical groove plate of a right lifting forked plate, lead screw fixing sleeves are fixed to a middle vertical plate and a right side plate of a lifting frame, lead screws are installed in shaft holes of the lead screw fixing sleeves, locking openings are correspondingly machined in a left guide rail plate on a left lifting forked plate and a right guide rail plate on the right lifting forked plate, hooked plates are arranged on the two sides of a guide rail of the hydraulic lift truck, and a slope is arranged on a front-end forked plate of the hydraulic lift truck. The hydraulic lift truck has the advantages that the height and the width of the lifting frame of the hydraulic lift truck can be adjusted, the requirement for lifting and transporting the functional vehicles with different cabinet widths through the same hydraulic lift truck is met, the functional vehicles can be automatically, safely and conveniently locked on the hydraulic lift truck, the functional vehicles can freely move onto the hydraulic lift truck, transportation is convenient, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic lifting vehicles, in particular to a hydraulic lifting vehicle used for carrying armored and removable switchgear function vehicles. Background technique [0002] In the prior art, most of the 10kV armored removable switch cabinets are center-mounted, that is, functional vehicles such as circuit breakers and isolation vehicles are placed in the middle of the cabinet. The platform truck sends the functional vehicle into or out of the cabinet. Since the height of the platform vehicle is fixed, it can only be fine-tuned within a few millimeters. In this way, the floor plates of the functional vehicle corresponding to different heights in the cabinet need to be matched with platform vehicles of different heights. In addition, due to The functional vehicle itself is heavy, and the platform of the platform vehicle has a certain height from the ground. During installation, several people are required t...

AI Technical Summary

Problems solved by technology

However, the hydraulic lift car in the prior art still needs a platform, and can only adjust the lifting height. Since the width is not adjustable, when the width of the cabinet is different, the corresponding cabinets of different widths still need to be matched with hydraulic lifts of different widths. In addition, there is a certain height between the fork plate and the ground at the front end of the hydraulic lift car, so that the hydraulic lift car cannot be completely grounded, and the difference between the radius of the outer circle used for the wheel walking on the ground and the guide rail walking function of VS1.VD4 is only 4 mm, which is relatively small, and several people are still required to lift the function car to the platform of the hydraulic lift car. In addition, the function car cannot automatically lock itself on the hydraulic lift car. In order to ensure its stable transportation, multiple people are required to operate together; Yes, when the function car is pushed or removed from the cabinet, because the function car itself is very heavy, it is easy to cause the hydraulic lift car to move backwards, and there is a hidden danger of the function car falling
