Description
Technical Field
The utility model relates to a metal mine mining is equipped, especially relates to a portable underground scraper fixing device.
Background
The scraper is commonly used for carrying and filling ores under the metal mine, and the installation and fixing modes of the scraper are various. Usually, a direct wooden top support is adopted for saving cost and time, the upper end of the support props against a top plate of a scraper chamber, and the lower end of the support props against the bottom of a scraper, so that the mode is simple and direct, but the scraper top is easy to loosen or even the scraper moves forwards to influence the safety of ore scraping due to vibration during ore scraping; some concrete foundations and embedded parts are tamped, secondary grouting is performed on the concrete foundations and the embedded parts, and the concrete foundations and the embedded parts are firm and safe, but the cost is high and the efficiency is low due to the fact that the engineering quantity is large, maintenance is needed, and the construction period is long.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome the above-mentioned defect that prior art exists, provide a fixed effectual, difficult not hard up portable harrow fixing device in pit.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a portable underground scraper fixing device, includes the base, and the scraper spiro union is on the base, and the tunnel bottom plate is equipped with the bolt hole in four base angle departments of base, the downthehole pre-buried rag bolt of bolt, be equipped with on the base with the screw hole of rag bolt looks adaptation, fill the cement explosive roll between rag bolt and the bolt hole.
Furthermore, reinforcing plates distributed at intervals are arranged on the base.
Furthermore, square holes distributed at intervals are formed in the base, and the reinforcing plate is located between the adjacent square holes.
Furthermore, the upper portion of the foundation bolt is provided with threads, and the foundation bolt is connected with the base through the threads.
Furthermore, the foundation bolt is sleeved with a tightening nut.
The utility model discloses a base is fixed the scraper at the tunnel bottom plate, possesses the quick simple and base of operation and can relapse repetitious usage, and is with low costs, advantage that work efficiency is high.
