Embodiment 1

[0061] This embodiment provides a planar sliding propulsion device for a shield machine, which can realize continuous propulsion and improve propulsion efficiency.

[0062] The technical solution adopted by the present invention is to combine Figure 1~2 As shown, a shield machine planar sliding propulsion device is provided, including a support frame 1, which is arranged on the upper side of the support frame 1, a seat plate 2 for supporting the shield machine 10, and a plurality of slides arranged on the lower side of the support frame 1. Shifting assembly 3 and a plurality of resistance increasing assemblies 4, and the reaction force device 5 that is arranged at the rear end of support frame 1, said shield machine 10 is provided with telescopic device 6 at one end, and said telescopic device (6) hydraulic push cylinder, said The hydraulic push cylinder provides thrust and pull for the shield machine. The hydraulic push cylinder 6 is supported by the reaction force device 5...

Embodiment 2

[0076] The present invention also provides a shield machine planar sliding propulsion method, using such as Figure 1-7 The propulsion device shown is realized; combined with Figure 8 As shown, the advancing method is:

[0077] When the telescopic device 6 is elongated and advanced, the resistance increasing assembly 4 is started to increase the resistance, so that the acceleration of the shield machine 10 relative to the seat plate 2 is greater than the acceleration of the support frame 1 relative to the ground;

[0078] When the telescopic device 6 shrinks, the resistance increasing assembly 4 is activated to reduce the resistance, so that the acceleration of the shield machine 10 relative to the seat plate 2 is smaller than the acceleration of the support frame 1 relative to the ground.

[0079] Specifically, the mass sum of the shield machine 10 and the expansion device 6 is M d , the mass of supporting frame 1 is M zc , the mass of seat plate 2 is M zb , the mass of ...

Abstract

The invention aims to overcome one or more defects in the prior art, and provides a plane sliding propelling device for a shield tunneling machine. The plane sliding propelling device comprises a supporting frame, a seat plate arranged on the upper side of the supporting frame and used for supporting the shield tunneling machine, a plurality of sliding assemblies, a plurality of resistance increasing assemblies and a counter-force device arranged at the tail end of the supporting frame, wherein the multiple sliding assemblies and the multiple resistance increasing assemblies are arranged on the lower side of the supporting frame; a telescopic device is arranged at one end of the shield tunneling machine, when the telescopic device extends for propelling, the resistance increasing assemblies are started to increase resistance, and thus the accelerated speed of the shield tunneling machine relative to the seat plate is greater than the accelerated speed of the supporting frame relative to the ground; and when the telescopic device retracts back, the resistance increasing assemblies are started to decrease the resistance, and thus the accelerated speed of the shield tunneling machinerelative to the seat plate is smaller than the accelerated speed of the supporting frame relative to the ground. According to the plane sliding propelling device, according to the different propellingprocesses, friction force between the propelling device and the ground is changed, continuous propelling can be achieved, energy consumption is further saved, and the construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a planar sliding propulsion device for a shield machine. Background technique [0002] In recent years, with the rapid development of cities, the construction of urban subways has developed rapidly, and the construction of urban rail transit has become more and more popular. Shield excavation is now the main method of urban subway construction, but when encountering some complex geology, other construction methods are required. When constructing a tunnel, when the shield machine reaches the excavated tunnel, it is necessary to empty push the shield machine through the excavated tunnel section. In order to ensure that the shield machine is smoothly pushed through the excavated tunnel section, the concrete guide platform in the excavated tunnel is used as the shield body support, and the steel rail laid on the guide platform is used as the shield body walking track. As ...
