Material receiving end protecting and distributing device for TBM belt conveyor

Abstract

A material receiving end protecting and distributing device for a TBM belt conveyor, which comprises a U-shaped baffle spliced by two lateral baffles and a back baffle and a buffering rubber plate, wherein the buffering rubber plate is fixedly mounted on the back baffle through a compressing assembly, and is erected on gummed tapes of the belt conveyor. According to the invention, the U-shaped baffle and the buffering rubber plate of the device can effectively avoid the impact breakage of residue materials to the upper surfaces of the belt conveyor gummed tapes; besides, the U-shaped baffle extends to the upper parts of the belt conveyor gummed tapes to be matched with the buffering rubber plate, so that the position of the residue materials unloading to a material receiving end of the belt conveyor can be limited in the gummed tape middle area to avoid the falling of residue materials under the joint action of the U-shaped baffle and the buffering rubber plate; therefore, the device has a simple structure, is convenient to mount, low in construction cost, and convenient and fast to maintain, has a remarkable effect, prolongs the gummed tape service life by more than 1 time, and prolongs the belt cleaning device service life by more than 2 times, and a cleaner operating environment is guaranteed.

Description

technical field [0001] The invention belongs to supporting equipment of a tunnel boring machine TBM, in particular to a material receiving end protection and material distribution device of a TBM belt conveyor. Background technique [0002] The gravel generated by TBM excavation is lifted to the top of the tunnel by the bucket arranged on the cutter head, dumped onto the belt conveyor as the cutter head rotates, and then transported to the supporting trolley, and then loaded onto the mine car or continuous belt conveyor. transported outside the cave. The TBM usually needs to be equipped with 2 to 3 sets of belt conveyors, and the gravel is relay conveyed on the belt conveyors. During the unloading process from the front belt conveyor to the rear belt conveyor, due to the lack of necessary protection devices and slag uniform distribution devices, it will bring There are two effects: one is that large-sized gravel or stones hit the belt of the rear belt conveyor, causing dama...

AI Technical Summary

Problems solved by technology

The TBM usually needs to be equipped with 2 to 3 sets of belt conveyors, and the gravel is relay conveyed on the belt conveyors. In the process of reloading and unloading from the front belt conveyor to the rear belt conveyor, due to the lack of necessary protection devices and slag uniform distribution devices, it will bring There are two effects: one is that large-sized gravel or stones hit the belt of the rear belt conveyor, causing damage to the surface of the belt and affecting the service life of the belt; meanwhile, small-sized gravel remains in the pits on the surface of the belt, which can easily cause The belt cleaner is damaged; second, it is impossible to ensure that the gravel is dumped to the middle of the belt conveyor. The gravel will fall from both sides of the belt, and even enter between the belt and the idler, causing damage to the belt, and the ground residue, muddy water More, increase the workload of cleaning
