Balance adjustable lifting device for building construction

Abstract

The invention discloses a balance adjustable lifting device for building construction. The device comprises a fixed bottom plate, a balance frame and a lifting protection plate, the balance frame is movably mounted at the upper part of the fixed bottom plate, and the middle position between the balance frame and the fixed bottom plate is butted and fixed through a middle balance ball. The middle balance ball is composed of a first arc-shaped pad, a second arc-shaped pad and an inner ball body, the first arc-shaped pad is movably connected to the inner side of the upper portion of the middle balance ball in a sleeving mode, and the second arc-shaped pad is movably connected to the inner side of the bottom of the middle balance ball in a sleeving mode. The inner ball body is movably installed in the middle of the interior of the middle balance ball, and the second arc-shaped pad, the first arc-shaped pad and the middle balance ball are fixed in a butt joint mode through the inner ball body. According to the balance adjustable lifting device for building construction, the lifting device is provided with a multi-angle balance adjusting structure, meanwhile, the lifting device has the advantages of being high in strength and being easy to store, and the lifting device is more convenient to use and operate.

Description

technical field [0001] The invention belongs to the technical field of lifting devices, and in particular relates to a lifting device for building construction, more specifically, a lifting device for building construction with adjustable balance. Background technique [0002] The balance-adjustable lifting device for building construction is a kind of lifting device that performs lifting and adjusting operations for operators in the construction process during the building construction operation. The lifting device can reduce the user's fatigue when working at heights. Difficulty, increase its safety when working at heights. [0003] A lifting device disclosed in the reference document CN103708321B includes first and second vertically moving guide shafts, the above-mentioned guide shafts are arranged in parallel and vertically with a predetermined gap; and the two ends of the second up and down guide shaft are supported to be rotatable; the first guide groove and the secon...

[0003] A lifting device disclosed in the reference document CN103708321B includes first and second vertically moving guide shafts, the above-mentioned guide shafts are arranged in parallel and vertically with a predetermined gap; and the two ends of the second up and down guide shaft are supported to be rotatable; the first guide groove and the second guide groove, the above-mentioned guide groove is a continuous thread arranged on the outer surface of the first and second up and down guide shaft; the first and a second up-and-down movement member, which are respectively fitted in the first and second up-and-down movement guide grooves to move along the first and second up-and-down movement guide grooves by the rotation of the first and second up-and-down movement guide shafts, and the present Compared with the invention, it does not have a multi-angle side spin balance structure, making it unsuitable for different venues

[0004] The existing lifting devices for building construction have certain disadvantages during use. The traditional lifting device for building construction adopts an integrated fixed structure design, so that the traditional lifting device for building construction does not have a multi-angle side-spin balance structure. When the lifting device is used on the site outside the pit, the lifting platform on the construction lifting device will be in a tilted state. The user usually adds a backing plate to keep the construction lifting device in balance. The balance effect is poor and the safety At the same time, the traditional lifting device for building construction does not have a lateral rotation fixing structure, which makes it impossible to fix the balance frame under the multi-angle adjustment structure; at the same time, the guard plate of the traditional building construction lifting device adopts a combined fixed structure design. Under the conditions of easy storage, the overall structural strength of the guard plate is reduced, and the storage and strength requirements cannot be taken into account, which brings certain adverse effects to users
