Description

Technical Field

[0001] The utility model belongs to the technical field of scraper chain maintenance, and in particular relates to a scraper chain maintenance tool. Background Art

[0002] The scraper conveyor is a solid material conveying device. The scraper chain is an important component of the scraper conveyor. The scraper chain serves as the traction mechanism of the scraper conveyor. Its working state restricts the normal operation of the scraper conveyor and affects the safety and output of the enterprise. During use, the scraper chain is very likely to loosen or break. When replacing the scraper chain, maintenance tools are required.

The device has a simple structure and is easy to operate, which can reduce the labor intensity of the staff and ensure the normal operation of production.

[0004] The above-mentioned disclosed patent has the following problems when used: the chains on both sides are tightened by tightening the nuts and pulled to the appropriate position, but when the device is in use, the adjusting nuts connected to the two hooks need to be tightened and adjusted separately, which makes it inconvenient to tighten the chains on both sides. When one staff member performs the adjustment, the adjustment time is increased and the work efficiency is reduced, and when two staff members perform the adjustment at the same time, the production cost is increased; in addition, the above-mentioned device cannot adjust the size of the replacement hook when in use. If a chain roller of a different model is encountered, if the chain roller is too thick, the hook will not fit perfectly with it, which will easily lead to decoupling, causing harm to the staff and damage to the solid material conveying device as a whole, increasing the production and maintenance costs.
