Building pipeline hoisting device

Abstract

The invention discloses a building pipeline hoisting device. The building pipeline hoisting device comprises a hoisting box and a mounting frame, the mounting frame is located at the top of the hoisting box, two movable hoisting claws are arranged below the hoisting box, the two movable hoisting claws are symmetrically arranged and slidably connected with the hoisting box, a controller and a driving motor are arranged on the two sides of the hoisting box correspondingly, a hollow driving cavity is formed inside the hoisting box, a double-thread rod connected with the driving motor is arrangedin the driving cavity, the double-thread rod is provided with two sets of external threads opposite in direction, the double-thread rod is sleeved with two driving plates rotationally connected with the double-thread rod in a threaded mode, threaded holes are formed in the driving plates, the lower ends of the driving plates extend out of the hoisting box and are fixedly connected with the movablehoisting claws, and a guide groove is formed in the bottom surface of the hoisting box. According to the building pipeline hoisting device, the driving motor drives the movable hoisting claws for grabbing, and through expansion air bags, attaching and fixing are performed so that the hoisting requirements of pipelines with different diameters can be met, the safety and the stability during hoisting can be greatly improved, and the device is suitable for being used for building construction.

Description

technical field [0001] The invention relates to construction technology, in particular to a construction pipeline hoisting device. Background technique [0002] Hoisting refers to the general term for the installation and positioning of equipment by cranes or hoisting mechanisms. In the process of overhaul or maintenance, various hoisting tools are used to lift equipment, workpieces, appliances, materials, etc. to change their positions. When installing or replacing, it is also necessary to use a hoisting device to hoist it to a suitable position first. During construction, a large number of pipelines will be laid, and equipment such as hoisting trucks are often needed. [0003] Chinese Patent Application Publication No. CN108622801A proposes a hoisting device for transmission pipelines. The pipeline to be hoisted is fixed by a butt joint up and down. Although it has a stable and fixed effect, the existing problems are also very obvious. First of all, its scope of applicatio...

[0003] Chinese Patent Application Publication No. CN108622801A proposes a hoisting device for transmission pipelines. The pipeline to be hoisted is fixed by a butt joint up and down. Although it has a stable and fixed effect, the existing problems are also very obvious. First of all, its scope of application is relatively large. Small, for pipes that are too large or too small, it cannot be effectively fixed; Chinese patent authorization announcement number CN209557787U also proposes a lifting device for pipes. By setting pipe supports and buffers, the operator directly places the pipe On the support, because the size and curvature of the tube support are adapted to the outer wall of the pipe, the pipe can be stably placed on the tube support, reducing the wear between the pipe and the tube support. Although the problem of size is solved to a certain extent, but in other When fixing the pipeline, the contact area with the pipeline is still relatively small, so that the pipeline cannot be completely fixed during the moving process, and the safety cannot be guaranteed
