Shield tunneling machine segment crane suspension

Abstract

The invention discloses a shield tunneling machine segment crane suspension. The suspension comprises four bearing legs (1), wherein the four bearing legs (1) are used for conveying segments, each bearing leg (1) comprises a foot part (2), a supporting leg (3) and a support frame (5), wherein the foot part (2) is arranged at the bottom of the bearing leg (1), and the bottom surface size of the foot part (2) is larger than the bottom surface size of the supporting leg (3) on the upper portion of the foot part (2), and the foot part (2) is provided with an inclined surface protruding supportingleg (3); the supporting frame (5) is arranged at the upper part of the supporting leg (3); a wear-resistant positioning plate (4) is arranged on the upward surface of the foot part (2) and the inclined surface of the supporting frame (5); and the wear-resistant positioning plate (4) is made of a polymer composite material artificial stone MMA, and is formed by pouring methyl propionate as a matrixand aluminum hydroxide as a filling material. According to the shield machine segment crane suspension, the service life of the wear-resistant positioning plate is greatly prolonged, the replacementfrequency is reduced, and meanwhile, the fixing of the segments and the hoisting stability are greatly facilitated.

Description

technical field [0001] The present application relates to a segment crane suspension of a shield machine, in particular to a segment crane suspension of a shield machine which is durable and capable of stably fixing and positioning the segments. Background technique [0002] Underground shield construction equipment At present, the suspension of the shield machine crane includes load-bearing legs, and the load-bearing legs include wear-resistant positioning plates. The existing wear-resistant positioning plates are mainly rubber products-industrial rubber plates, etc. After material analysis and use practice, it is found that It has more deficiencies: [0003] 1. The strength and hardness of industrial rubber sheets are low, especially in the harsh environment where the shield machine works, it is easy to damage, crack, and age, and needs to be replaced frequently, which is time-consuming and laborious. [0004] 2. The industrial rubber sheet is a hyperelastic material with...
