Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 and figure 2 As shown, a lifting device with a double-layer lifting function includes a guide structure 1 , a first lifting mechanism 2 and a second lifting mechanism 3 . The first lifting mechanism 2 and the first slewing support 2-6 are connected to the base 1-1. The second lifting mechanism 3 is connected to the base 1-1 through a second slewing support 3-6. The first slewing support 2-6 and the second slewing support 3-6 are arranged coaxially with the center hole of the base 1-1 of the guide structure 1, respectively, and are respectively fixed on the upper and lower sides of the plate of the base 1-1. The lifting mechanism 2 and the second lifting mechanism 3 provide power for the movement.

[0019] Such as image 3 As shown, the guide structure 1 includes: a base 1-1, four evenly distributed guide shafts 1-2 and guide plat...

Abstract

The invention discloses a lifting device with a double-layer lifting function, belongs to the technical field of mechanical devices and aims to solve the problems of structural redundancy and low safety of the existing lifting device. The lifting device comprises a guide structure, a first lifting mechanism and a second lifting mechanism, wherein a first rotary support of the first lifting mechanism is connected to a base of the guide structure; the second lifting mechanism is connected to the base of the guide structure through a second rotary support; and the first rotary support and the second rotary support are respectively coaxial with a center hole of the base of the guide structure and fixed on the upper side and the lower side of a flat plate of the base respectively to be used forproviding power for the movement of the first lifting mechanism and the second lifting mechanism. According to the lifting device, a ball screw pair is used as a transmission component and the solidball screw and the hollow ball screw are used to drive a double-layer lifting mechanism in an ingenious manner of being coaxially cooperative, thereby greatly simplifying a transmission system and solving the problems of structural redundancy and huge volume of the traditional lifting machine. Besides, double locking ensures the safety of the lifting device reliably.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a lifting device with a double-layer lifting function. Background technique [0002] In the assembly process of some large-scale mechanical equipment, it is often necessary to lift some heavy parts to a certain height before installation. The Chinese patent with the publication number "CN107352459A" discloses a double-deck lifting lift, which uses a hydraulic system as a power source, and pushes a scissor support arm through a hydraulic cylinder to lift the double-deck table. However, since the two-story lifting platform requires two sets of independent mechanisms, and the pump station needs to be carried during the work process, it will inevitably bring about structural redundancy and bulky problems. In addition, the system pressure caused by external loads is mainly caused by the equipment during the height maintenance process. It is borne by the one-way valve in ...
