Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bucket elevator maintenance auxiliary tools, in particular to a safety device for preventing a bucket elevator chain from moving. Background Art
[0002] Bucket elevators are widely used in industries such as mining, chemical processing, food processing, and construction to lift bulk materials from low to high locations. The bucket chain is a key component in the elevator, connecting the buckets and transmitting power. However, in actual use, the chain can shift or become detached for various reasons, leading to equipment failure or even accidents.
[0003] When repairing the mechanical part of the lifting bucket, it is only necessary to cut off the power to the equipment and hang up the maintenance sign. However, the lifting bucket device is a vertical structure with its own gravity and no braking device. It is easy for the lifting bucket to move downward under the action of gravity, threatening the personal safety of maintenance personnel.
[0004] Therefore, it is urgent to design a safety device to prevent the bucket chain from moving to solve the problem that only the power is cut off and the maintenance sign is hung without any braking device threatening the personal safety of maintenance personnel. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of the present utility model is to provide a safety device for preventing the bucket chain from moving.
[0006] The technical solution adopted by the utility model to solve its technical problem is: a safety device for preventing the bucket chain from moving, including a chain stop rod and a stop fixing rod, the chain stop rod is provided with an insertion rod, the chain stop rod and the insertion rod form a T shape, the brake fixing rod is divided into an upper fixing rod and a lower fixing rod, and a baffle is provided between the upper fixing rod and the lower fixing rod.
[0007] Specifically, the chain stopper rod is a long rod, and the chain stopper rod is a horizontal rod.
[0008] Specifically, the insertion rod is vertically arranged at a position slightly to the right of the middle of the chain stop rod, the insertion rod and the chain stop rod form a T shape, and the insertion rod is inserted into the chain hole.
[0009] Specifically, the upper fixing rod is arranged above the chain stop rod, and the upper fixing rod is fixedly installed outside the hoist casing. The upper fixing rod limits the chain stop rod from moving upward.
[0010] Specifically, the lower fixing rod is arranged below the chain stop rod, and the lower fixing rod is fixedly installed outside the hoist casing, and the lower fixing rod limits the lower moving space of the chain stop rod.
[0011] Specifically, the baffle is arranged on the upper fixing rod through a pin shaft. The baffle naturally hangs down by gravity and can rotate through the pin shaft and limit the displacement of the chain stop rod.
[0012] The utility model has the following beneficial effects:
[0013] The safety device for preventing the movement of the lifting bucket chain designed by the utility model: 1. It has a simple structure and is easy to operate. Without a complex debugging and installation process, it can be quickly put into use.
[0014] 2. It has high reliability. The chain stop rod can effectively prevent the lifting bucket chain from moving.
[0015] 3. The safety device of the invention can be widely applied to various types of lifting bucket equipment, especially suitable for occasions with harsh working environments and high requirements for equipment safety. BRIEF DESCRIPTION OF THE DRAWINGS
