Embodiment Construction
[0033] The lifting device in the present invention will be described in detail below in conjunction with the accompanying drawings.
[0034] Such as figure 1 , 2 As shown, a lifting device with a universal wheel, which includes the following components:
[0035] 1. Base 10
[0036] The base 10 is fixed on the column 70. For example, the base 10 can be integrated with the column 70 by welding; If a plurality of flanges are arranged on the body from top to bottom, the position of the base 10 can be adjusted along the axial direction of the column 70 .
[0037] 2. Universal runner assembly 20
[0038] Such as figure 1 , 2 As shown, the universal wheel assembly 20 is used to enable the telescopic puller 30 to rotate up and down and / or left and right without hindrance relative to the base 10 under the action of an external force. For the universal wheel assembly 20, reference may be made to the prior art. For example, the universal ball joint structure.
[0039] 3. Telescop...

The invention belongs to the technical field of building construction, and particularly relates to a hoisting device with a universal wheel. The hoisting device comprises a pedestal, and a telescoping pulling bar; a hinged end of the telescoping pulling bar is rotataby connected with the pedestal through a universal wheel assembly; a hoisting end of the telescoping pulling bar is respectively connected with a hoisting pulley block and a limiting pulley block; a cable rope is disposed at the hoisting end of the telescoping pulling bar and is used for driving the telescoping pulling bar to rotate left and right around the hinged end; the hoisting device also comprises the hoisting pulley block for connecting a weight with the hoisting end of the telescoping pulling bar, and the limiting pulley block for driving the telescoping pulling bar to rotate up and down around the hinged end and for limiting the pitch angle between the telescoping pulling bar and the pedestal. The hoisting device of the invention not only maintains the flexibility of short bar operation, but also gives play to the functionality of long bar horizontal transport, accelerates the progress of weight hoisting, provides new thinking and methods for vertical transport and horizontal transport of large-scale hoisting in building engineering, and has very good popularization value.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a hoisting device with a universal runner. Background technique [0002] In the prior art, it is a conventional installation method to install heavy objects through lifting devices, but small lifting devices usually can only lift heavy objects in the vertical direction, but cannot transport heavy objects in the horizontal direction or the distance of horizontal transportation of heavy objects Very limited; although the large-scale hoisting device can not only lift heavy objects in the vertical direction, but also can transport heavy objects in the horizontal direction, the large-scale hoisting device has a complex structure and high cost. Therefore, how to implement a relatively simple structure that can not only lift heavy objects in the vertical direction, but also transport heavy objects in the horizontal direction over a long distance is a technical ...
