Tool hoisting device used for shield tunneling machine

Abstract

The invention discloses a tool hoisting device used for a shield tunneling machine. The tool hosting device comprises a hoisting device body. The hoisting device body comprises a hoisting shaft, a connecting plate, a rod body and a lifting hook. One end of the hosting shaft is fixedly connected with a grabbing head of a splicing device, and the other end of the hoisting shaft is fixed to the bottom of the connecting plate. One end of the rod body is fixedly connected to the side face of the connecting plate, and the other end of the rod body is connected with the lifting hook. The lifting hookcan rotate around the radial end of the rod body. When the grabbing head of the splicing device is fixedly connected with the hoisting shaft, a segment splicing and lifting device rotates and rises or falls to drive the hosing device body to change in altitude, and thus, a tool hung on the lifting hook is transferred towards a cabin of the tool hoisting device. By adoption of the design, the toolhoisting device is simple and reliable in structure, the hoisting shaft is grabbed through the grabbing head of the splicing machine on the shield tunneling machine, and then, the whole tool hoistingdevice is driven to move.

Description

technical field [0001] The invention relates to a shield mechanism, in particular to a tool hoisting device for a shield machine. Background technique [0002] The knives on the shield machine are wearing parts. After a period of use, the knives will be severely worn. At this time, the knives need to be replaced so that the shield machine can maintain a good working condition. However, it is very troublesome to replace the cutter at present, the labor intensity of the workers is high, and the replacement efficiency is low. [0003] The announcement number is CN 204702458 U disclosed a kind of shield machine tool hoisting structure, such as figure 1 As shown, including the base plate 1', the base plate 1' is provided with a hoisting seat 2', the hoisting seat 2' is provided with a driving motor 3', and the driving motor 3' is driven and connected with a ball screw seat 4', the ball screw A ball screw 5' is arranged inside the seat 4', a moving block 6' is connected to the b...

[0003] The announcement number is CN 204702458 U disclosed a kind of shield machine tool hoisting structure, such as figure 1 As shown, including the base plate 1', the base plate 1' is provided with a hoisting seat 2', the hoisting seat 2' is provided with a driving motor 3', and the driving motor 3' is driven and connected with a ball screw seat 4', the ball screw A ball screw 5' is arranged inside the seat 4', a moving block 6' is connected to the ball screw 5', a lifting rod 7' is connected to the moving block 6', and a lifting hook 8' is slidingly connected to the lifting rod 7', Because the cutting tool needs to be hoisted into the man cabin of the shield machine, and the installation position of the man cabin is generally installed on the top of the shield machine, and the height difference is large, the disadvantages caused by the above scheme: 1. A single knife of the shield machine is generally more than 150kg, and the ball The 5' lead screw is easy to bend and deform under the condition of long-distance load; 2. The structure and installation accuracy of the ball screw 5' are high, the processing cost is high, and the requirements for the use environment are high; 3. The ball screw 5' is used for transmission, Requires complex power system and supporting structures and devices
