Culvert pipe clamping and lifting device for road construction

Abstract

The invention discloses a culvert pipe clamping and hoisting device for road construction. The culvert pipe clamping and hoisting device is characterized in that a wire roller assembly and a driven shaft are driven by a motor to rotate simultaneously to achieve an upgrading function, and meanwhile, a worm is driven by the rotating driven shaft to rotate to clamp a culvert pipe, so that the safetyof hoisting in culvert pipe construction is greatly improved, and the problem of low moving stability of a culvert pipe in the prior art is effectively solved. A driving motor is arranged on a workingplatform; the driving motor is connected with a lifting assembly; the lifting assembly comprises the wire roller assembly connected with an output end of the driving motor and a steel wire connectingthe wire roller assembly and the upper part of a lifting plate; the upper end of the steel wire is fixed to the upper end of the lifting plate; the lower part of the steel wire winds around the wireroller assembly; and sliding blocks embedded in guide grooves which are formed in the lifting plate are fixed on the two sides of the rear part of the working platform.

Description

technical field [0001] The invention relates to a construction machine, in particular to a clamping and lifting device for culvert pipes used in road construction. Background technique [0002] Culvert pipe is a kind of pipeline buried below the surface, which is cast with reinforced concrete, commonly known as cement pipe. Small culverts are also made of metal materials. Under the whole section of the cofferdam dam, it is used as a water diversion pipeline, and in general, it is used as a water delivery pipeline. At present, the water supply and drainage pipelines in most cities in my country use cement pipes as culverts. [0003] At present, in the process of road construction and bridge erection, culvert pipes are used to realize the smooth flow of water on both sides of the road. In the existing road construction, the burying of culvert pipes needs to be lifted by cranes or cranes, and fixed by cables. During the lifting process, the culvert pipe is very easy to rotat...

Problems solved by technology

[0003] At present, in the process of road construction and bridge erection, culvert pipes are used to realize the smooth flow of water on both sides of the road. In the existing road construction, the burying of culvert pipes needs to be lifted by cranes or cranes, and fixed by cables. During the hoisting process, the culvert pipe is very easy to rotate, and it is also easy to slip from the cable, which is not safe and prone to accidents
