Abstract

The invention relates to a multi-functional simulation experiment system for a mining elevator. The system comprises a head frame fixed on a concrete base, as well as an anti-explosion traction test system, a car protection test system, a flexible guide rail guide test system, a water-pouring simulation test system, a car and a counter weight which are arranged on the head frame. Hoisting rope tension dynamic regulating test, car over-speed or out of control protection test, car top reaching and bottom landing safety protection test, flexible guide rail tension dynamic balance test, car running stability test, tail rope hanging reliable test, car enduring water-pouring test for simulating hoistway water penetration and the like can be realized; and a safe and reliable multi-functional simulation experiment platform which has compact structure, is convenient to operate, is time-saving and labor-saving and can simulate the mine well environment is provided for lifting materials and personnel under a mine.

Description

technical field [0001] The invention relates to a multi-functional simulation experiment system of a mining elevator, which is especially suitable for the simulation operation test of the mining elevator for lifting underground materials and personnel in mines. Background technique [0002] The lifting of personnel in the process of underground mining in mines is currently mainly carried out with hoists and cages. For the mining of underground multi-level working faces, especially when lifting materials and personnel with a lifting height of less than 400m, the use of traditional hoists has high costs and engineering construction. The problem of long cycle time; secondly, in the process of lifting personnel with hoists, the occupants in the cage cannot control the lifting process, so that information cannot be transmitted to the wellhead or underground, and emergencies during transportation cannot be communicated with the wellhead and underground personnel. Direct connection...

Problems solved by technology

However, due to the harsh working environment underground and the shaft is easily deformed, the T-shaped guide rails of the existing industrial common elevators cannot meet the hoisting requirements of the mine. At present, there is no dynamic stability test system for the elevator car based on flexible guide rails; at the same time, the traction rope The connecting device adopts compression spring form and rubber form. Although it plays the role of buffer and shock absorption, due to the error of the manufacture of the traction rope and the difference in materials, it is easy to cause the tension force of the traction rope to be unbalanced after a period of use. At present, there is no dynamic tensioning device for the traction rope of the elevator system, and there is no test system based on the device; the existing safety gear system can only adapt to the safety braking of the rigid guide rail, and the elevator system does not currently have a brake rope-based tensioning device. The safety braking system also does not have a safety gear anti-drop braking test system based on the brake rope at different car running speeds; although ordinary elevators have pit hydraulic buffer devices and rope grippers, mine elevators are The surface interval is large, the running speed is fast, and the load of the car is large, so there are phenomena of the car's top rushing and falling. At present, there is no anti-rushing and bottoming protection system for the elevator car, and there is no protection system for the elevator car at different speeds. The test system for jumping to the top and bottom; due to the harsh geological conditions in the mine, the well sees water frequently, and industrial elevators mainly operate in a dry environment, so there is no water spraying environment for the car. At present, there is no water spraying simulation test system for the elevator system The car is mainly used for the lifting of people and general goods, but it cannot transport the moving car bodies such as mine cars, so that the transportation of the car body materials at the wellhead of the mine cannot be realized; there is no receiving device for the car to enter the car and the wellhead The pushing device that pushes the mine car into the car; at present, there is no multi-functional simulation test system that integrates the above test systems for mining elevators at home and abroad. Big, inconvenient to handle, and unsafe
