Problems solved by technology

[0003] The purpose of the present invention is to address the deficiencies in the prior art, and to provide a non-stop vulcanization method for the continuous belt conveyor in the TBM sliding section; The rotation causes large power consumption, and the belt needs to be shut down for vulcanization, resulting in slow project progress and large capital investment.

Embodiment 1

[0023] like figure 1 Shown: a kind of TBM sliding section continuous belt machine extends TBM non-stop vulcanization method, comprises the following steps:

[0024] 1) Preparation before taxiing: before TBM taxis, there must be enough belt storage capacity in the belt storage bin 15; use clamping device 1 3 and clamping device 2 7 to fix the belt passing through the vulcanization platform so that the belt cannot Move, there are two vulcanization platforms located between clamping device one 3 and clamping device two 7, the vulcanization platform is used to vulcanize the joints of the belts so that the newly added belts are connected to the original belts, and between the vulcanization platforms A belt release device 5 can be placed between them, and the belt release device 5 can add belt rolls; clamping device one 3 and clamping device two 7 fix the belt on the vulcanization platform, so that the belt on one side of the tape storage bin 15 can be fixed It is fixed with the be...

Embodiment 2

[0031] like figure 2 As shown, on the basis of Embodiment 1, in the step 1), the preparation before taxiing also includes installing a pressure detection device 17 on the tail drum 10, and the signal output of the pressure detection device 17 is connected to the PLC control system of the TBM; The pressure detection device 17 adopts a bearing seat type load sensor, and the pressure detection device 17 is installed on the bearing seat 18 of the tail drum 10, and the active force of the belt on the tail drum 10 will act on the bearing seat through the rotating shaft of the tail drum 10 18, therefore, installing a pressure detection device 17 between the bearing seat 18 and the fixed frame 19 can effectively detect the force condition of the tail drum 10, and the pressure detection device 17 is mainly used in steps 2), 3) and 5). In use, the function is shielded by the PLC control system after the TBM runs to the tunneling section; specifically, the pressure detection device 17 c...

Abstract

The invention discloses a vulcanization method capable of enabling continuous belt conveyor to extend and a TBM not to be stopped at a sliding stage of the TBM. The method comprises the following steps that (1) preparation is carried out before sliding, specifically, a clamping device is used for fixing a belt, and the tension force of a frequency conversion tension winch is adjusted; (2) the beltis extended, specifically, the belt is dragged by a machine tail roller to realize belt extension; (3) the vulcanization of a belt joint is carried out, specifically, when 18-26 hours of stored beltin a belt storage bin remains, the vulcanization operation is carried out; (4) the belt is stored in the belt storage bin, specifically, when remaining belt does not exist in the belt storage bin, theclamping device is loosened, the belt is pulled into the belt storage bin, and the belt is re-fixed; (5) the belt is subjected to secondary extension vulcanization, specifically, when the belt is required to be added again, the step (3) and the step (4) are repeated; and (6) a tunneling section is linked, specifically, when the TBM slides to a tunnel face, the tension force of the frequency conversion tension winch is adjusted, a driving roller is started, and a TBM main engine is started. According to the a vulcanization method capable of enabling continuous belt conveyor to extend and a TBMnot to be stopped at sliding stage of the TBM , the TBM does not stop in a drilling and blasting section and is subjected to vulcanization, the power consumption when the belt extends is reduced, theproject progress can be speeded up, and the capital investment is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a non-stop vulcanization method for a continuous belt conveyor in a TBM sliding section when the TBM is extended in a drilling and blasting section. Background technique [0002] When the TBM encounters the drill-and-blast section during the excavation process, it uses the sliding method to pass through it. After passing the drill-and-blast section, it goes to the excavation section and then excavates. Start the transmission drum to rotate and drive the belt to move (at this time, the movement adopts low-speed operation), then the TBM main engine starts and starts to slide. The auxiliary push cylinder of the TBM main engine is dragged and matched with the tail roller on the trailer, and the tail roller drags the belt. Pull out the lower belt from the storage bin. During the process of pulling out, the upper and lower belts move at the same time. When the belt in the s...
