Coal mine underground multifunctional fork lift truck with storage battery

Abstract

The invention belongs to the technical field of design and manufacturing of coal mine auxiliary transportation equipment, and particularly relates to a coal mine underground multifunctional fork lift truck with a storage battery. In order to meet various requirements for coal mine underground road surface cleaning, material carrying and the like, the coal mine underground multifunctional fork lift truck comprises a working mechanism on the front portion, a quick-changing mechanism connected with the working mechanism through a gate oil cylinder, a crank mechanism connected with the quick-changing mechanism, a front frame connected with the crank mechanism, a rear frame connected with the front frame through hinge pins, a battery bracket connected with the rear frame and the direct current storage battery connected to the battery bracket in an inserted mode. According to the coal mine underground multifunctional fork lift truck, the width of a truck body is reduced, so that the moving range of the fork lift truck under a coal mine is expanded; and a carrying function is added, so that the function singleness of the fork lift truck is overcome.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of coal mine auxiliary transportation equipment, and in particular relates to a coal mine underground storage battery multifunctional scraper. Background technique [0002] The battery multi-functional scraper is an auxiliary scraper powered by a vehicle-mounted large-capacity battery in coal mines. It consists of a bucket, fork, quick-change mechanism, crank mechanism, front frame, rear frame, battery bracket, battery, hydraulic pressure, etc. System, electrical system, automatic fire extinguishing system. There are two kinds of working mechanisms: bucket and fork, which can be replaced quickly through the quick change mechanism. The bucket is used to clean the road surface, and the fork is used to carry materials and electromechanical equipment. [0003] The currently used scraper trucks are all powered by diesel engines. When working in coal mines, the vehicles need to be freque...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned problems existing in the existing battery scraper, the present invention provides a multifunctional battery scraper, which realizes quick replacement of different tasks through a quick-change mechanism, so as to meet various needs such as cleaning roads and transporting materials in coal mines ;The width of the vehicle body is reduced as much as possible, so that the vehicle can walk in the trough and the alley; the large-capacity coal mine special lead-acid battery is used as the power source, and the low-voltage AC frequency conversion technology is used for speed regulation, and the operation of the LHD is adjusted according to the load size speed, to achieve the purpose of energy saving, and make the operation tasks performed by the scraper in the harsh environment of the coal mine more safe, stable and environmentally friendly
