Embodiment 1

[0027] see Figure 1-3 , a steel pipe installation lifting device for a shield machine, including a bottom plate 1, an upper plate 7 and a lifting assembly, wherein a guide rod 4 is fixedly connected to the bottom plate 1, and several groups of guide rods 4 are installed on the bottom plate 1. The plate 7 is fixedly connected to the guide rod 4, the lifting assembly is arranged and installed between the bottom plate 1 and the upper plate 7, and the clamping assembly is connected and installed on the lifting assembly, and the steel pipe 18 is clamped on the clamping assembly, and the steel pipe 18 is clamped and installed On the clamping assembly, the lifting action is performed by the lifting assembly; further, the clamping assembly includes a clamping seat 10, a clamping block 11 and an adsorption assembly, and the adsorption assembly is arranged on the clamping block 11, The steel pipe 18 is effectively adsorbed by the adsorption assembly; the clamping block 11 is arranged a...

Embodiment 2

[0034] In this embodiment, the following improvements are made on the basis of the above embodiments, wherein a transfer assembly is arranged and installed on the base plate 1, and the transfer assembly includes rollers and crawlers 3, and the rollers are rotatably mounted on the base plate 1 and the The crawler belt 3 is swelled and installed on the rollers, and a power unit is connected to the rollers. The power unit drives the rollers to rotate, and the stability of the device during the transfer process is greatly improved under the action of the crawler belts 3 .

[0035]The working principle of the present invention is: during the use of the device, the adjacent clamping blocks 11 are hinged through the connecting rod 17, so that the clamping blocks 11 of a single group have certain flexibility and can adapt to different Diameter steel pipe 18; when the adsorption component on the clamping block 11 is adsorbed on the steel pipe 18, the piston rod of the telescopic rod 20 ...

Abstract

The invention discloses a lifting device for installing a steel pipe of a shield machine, which comprises a bottom plate, an upper plate and a lifting assembly, the lifting assembly is arranged and installed between the bottom plate and the upper plate, and a clamping assembly is connected and installed on the lifting assembly, and the clamping assembly The upper clamps the steel pipe; the clamping component includes a clamping seat, a clamping block and an adsorption component, the adsorption component is arranged on the clamping block, and the clamping block is arranged and installed on the clamping seat. Because the adjacent clamping blocks of this device are hinged by connecting rods, a single set of clamping blocks has certain flexibility and can adapt to steel pipes of different diameters; The piston rod is in contact with the steel pipe, which improves the stability during the clamping process; at the same time, when the device lifts the steel pipe to the corresponding position, the adsorption components on both sides are contacted and adsorbed, and the steel pipe is quickly pushed to the The corresponding position, improve the actual use effect.

Description

technical field [0001] The invention relates to the field of tunnel processing, in particular to a steel pipe installation and lifting device for a shield machine. Background technique [0002] The shield machine is the main equipment for tunnel construction. During the manufacture and maintenance of the shield machine trailer, many steel pipes need to be installed and disassembled. Generally, during the installation process, each steel pipe needs to be hoisted to the top of the trailer for pressing. Tight, then a worker stands on a step ladder and secures the pipe to the top of the trailer. [0003] Due to the different diameters of the pipes, the existing lifting device is likely to cause unstable clamping when clamping the pipe; and during the clamping process, the existing lifting device for the steel pipe used in the shield machine needs to be clamped To the maximum diameter of the steel pipe, it is not easy to install the steel pipe; [0004] Furthermore, a lifting d...
