Constant torque integral broken belt arresting device and its arresting method

Abstract

The invention discloses a constant-torque integral broken belt catching device and a catching method thereof. The broken belt catching device consists of a rack, an upper cross beam, a lower cross beam, a rotating shaft, an upper catching rack, a lower catching rack and a driving system, wherein the upper cross beam and the lower cross beam are respectively and fixedly arranged on the upper and lower parts of the rack; the rotating shaft transversely penetrates through the middle of the rack and is arranged on the rack; the upper catching rack is arranged on the rotating shaft and corresponds to the bottom surface of the upper cross beam; the rotating surface of the lower catching rack is downwards articulated with the rack and corresponds to the top surface of the lower cross beam; the driving system consists of two symmetrically-arranged steel wire ropes, two symmetrically-arranged sheave wheels and two symmetrically-arranged weight boxes; the upper catching rack is driven to rotate under the gravity action of the weight box, so that a broken upper-layer rubber belt is supported and clamped, and thus rubber belt catching is realized. When belt breakage occurs, the rubber belt is suddenly accelerated after relaxation, and the upper catching rack and the lower catching rack are triggered to across a dead point so as to rotate respectively towards the upper cross beam and the lower cross beam, so that the rubber belt is rapidly caught. The constant-torque integral broken belt catching device is rapid and accurate in response and free from incorrect action.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to a broken belt arresting device of the belt conveyor. Background technique [0002] Existing broken belt arresting devices are divided into two-eared arresting devices, hydraulic integral arresting devices and mechanical integral arresting devices. The two-ear type is used for dispersive arrest, which has low arresting power and is prone to misoperation. The hydraulic integral arresting device system is complex, there are many fault points, and it is difficult to arrange high-pressure oil pipes along the line, and the energy consumption is high, and the trigger is easy to cause misoperation by sliding down the tape. After the triggering of the mechanical overall capture device, the torque varies with the angle and is not constant. The capture shoe is in point and line contact, which may easily cause tape loss and secondary belt breakage accidents. The capture beam and side frame are connected b...

The hydraulic integral arresting device system is complicated, there are many fault points, and it is difficult to arrange high-pressure oil pipes along the line, and the energy consumption is high, and the trigger is easy to cause malfunction when the tape slides down to catch

After the triggering of the mechanical overall capture device, the torque varies with the angle and is not constant. The capture shoe is in point and line contact, which may easily cause the loss of the tape and cause a secondary broken belt accident. The capture beam and the side frame are connected by bolts. The bolts are stressed during fishing, and local bolts will break when they are sheared, which brings danger to the use of equipment
