Problems solved by technology

[0002] Ordinary gantry uses cables for activities, and only one batch of items can be lifted at a time. The second batch of items needs to be hoisted after the first batch of items are hoisted in place, and then the cables can be lowered. The work efficiency is relatively low.

Embodiment Construction

[0009] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0010] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0011] Such as figure 1 A gantry frame shown includes a bracket 1. The bracket 1 is a tapered steel structure bracket 1. The two brackets 1 are arranged symmetrically. The top of the bracket 1 is connected to each other through a rotating shaft 3. One end of the rotating shaft 3 is connected to a motor 2. There are two gears 4 arranged symmetrically. The diameters of the gears 4 are the same. A rack 5 is connected to each gear 4. The rack 5 i...

Abstract

The invention discloses a portal frame. The portal frame comprises brackets, wherein a rotary shaft is connected between the two brackets; one end of the rotary shaft is connected with a motor; two gears are symmetrically arranged on the rotary shaft; each gear is connected with a rack; and the two racks are mutually connected by a plurality of connection rods. Objects are hung on the connection rods, the rotary shaft is rotated, the racks and the gears are engaged to rotate so that the objects are lifted up; and the objects can be hung on the plurality of connection rods so that the objects can be continuously and sequentially lifted up and the working efficiency is improved.

Description

technical field [0001] The invention relates to a gantry frame. Background technique [0002] What common gantry adopts is that cables are used for activities, and only one batch of items can be lifted at a time, and the second batch of items needs to be hoisted after the first batch of items are hoisted in place, and then the cables can be lowered to carry out, and the work efficiency is relatively low. Contents of the invention [0003] The invention relates to a gantry frame, which can simultaneously lift multiple batches of articles and improve work efficiency. [0004] In order to achieve this purpose, the structure adopted in the present invention is: a gantry frame, including brackets, the two brackets are connected to each other through a rotating shaft, one end of the rotating shaft is connected to a motor, and the rotating shaft is symmetrically connected through a shaft coupling. Two gears with the same diameter are connected, each gear is connected with an ann...
