Problems solved by technology

[0002] At present, in the field of tunnel excavation construction, especially in the field of small-diameter tunnel construction, the design of the roadheader is very limited due to the limited space, especially the lifting device of the equipment. The performance requirements of the lifting capacity make the design of the lifting device difficult
[0003] In the prior art, the lifting device can generally only be implemented in a large construction space, but it is difficult to implement in a small-diameter tunnel space
With the increase of urban sewage and pipe gallery projects, the construction space is getting smaller and smaller, and the requirements for the lifting device of the excavation equipment are getting higher and higher, and the existing construction technology solutions can no longer overcome many constraints

Abstract

The invention discloses an electric hoisting device for an air duct, comprising: a hoisting frame for carrying the air duct, a guide wheel assembly for supporting and driving the movement of the air duct, a transmission device for driving the movement of the guide wheel assembly, and a A limit device that restricts the movement of the guide wheel assembly after the air duct is lifted in place. The hoisting frame is provided with a guide rail for moving the guide wheel assembly and a limit hole for fixing the limit device. The transmission device is located on one side of the hanger. The transmission device is connected with the guide wheel assembly. The air duct electric hoisting device provided by the invention can meet the requirements of narrow construction space, and the device is efficient and reliable, has good safety performance, and can be widely popularized and applied.

Description

technical field [0001] The invention relates to the technical field of hoisting, and more specifically, relates to an electric hoisting device for an air duct. Background technique [0002] At present, in the field of tunnel excavation construction, especially in the field of small-diameter tunnel construction, the design of the roadheader is very limited due to the limited space, especially the lifting device of the equipment. The performance requirements of the lifting capacity make the design of the lifting device difficult. [0003] In the prior art, the lifting device can generally only be implemented in a large construction space, but it is difficult to implement in a small-diameter tunnel space. With the increase of urban sewage and pipe gallery projects, the construction space is getting smaller and smaller, and the requirements for the lifting device of the excavation equipment are getting higher and higher, and the existing construction technology solutions can no...
