Description
Technical Field
The utility model relates to a shield constructs and detects technical field, especially indicates a shield constructs band conveyer detection device that skids.
Background
The belt conveyor is important muck conveying equipment for the earth pressure balance shield, and muck is transferred to the belt conveyor through the screw conveyor and then is conveyed out of a hole through the belt conveyor. When the belt conveyor works, the driving roller rotates to drive the belt to run, and the belt drives the driven roller to rotate through friction between the belt and the driven roller. Because the belt has certain elongation, after the belt feeder operates for a period of time, because the belt elongation leads to the tensile force not enough, can produce the belt and skid, influence belt area speed. In addition, the belt conveyor is arranged below a discharge port of the spiral conveyor, the environment is severe, and the slag soil is easy to drop on the belt, so that the friction force between the belt and the roller is insufficient, the belt slips and the belt speed is influenced. If the slip is not handled in time, the following damage may be caused to the belt: 1. the abrasion of the rubber belt and the roller is aggravated, the service life of equipment is shortened, and even the belt is scrapped; 2. the equipment generates heat seriously, which affects the construction environment; 3. the construction cost is increased, and the construction efficiency is reduced.
The existing belt conveying device and belt slip detection method with application number CN201910857579.6 have poor integration of the structure with the shield belt conveyor, and the test method is complex, so that the slip detection data of the shield belt conveyor is inaccurate, and further improvement and design are needed.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 and 2, in embodiment 1, a belt conveyor 12 on a shield machine is located at the lower part of a spiral conveyor 11 and used for receiving muck falling from the spiral conveyor, a belt 10 of the belt conveyor is arranged on a driven roller 9, the driven roller 9 is rotatably connected with a roller shaft 8 through a rotating member 13, the rotating member adopts a bearing assembly, and when the belt conveyor works, the belt drives the driven roller to rotate around the roller shaft. The rotary drum shaft 8 is provided with an outer support 3, the driven drum 9 is internally provided with a rotary support 7, the rotary support 7 rotates along with the driven drum, and at the moment, the rotary support rotates relative to the outer support. The outer bracket 3 is provided with a proximity switch 1, the rotating bracket 7 is evenly provided with detection bolts 6, and the proximity switch 1 corresponds to the detection bolts 6. Proximity switch 1 is connected with the backstage controller, still can be connected with the siren on the controller, when proximity switch detects skidding appearing, the siren can send out the police dispatch newspaper, and the staff of being convenient for in time handles.
Further, the outer support 3 is arranged along the radial direction of the roller shaft 8, and the lower part of the outer support 3 is fixed on the roller shaft 8 through a fixing bolt 4; proximity switch 1 sets up on 3 upper portions of outer support and fixes through lock nut 2, adjusts proximity switch's position through adjusting lock nut, and the accurate detection bolt that reads of being convenient for.
Further, the rotating frame 7 is an annular frame which is sleeved on the roller shaft 8 and is connected to the driven roller 9 through a set screw 5 and synchronously rotates along with the driven roller.
