Problems solved by technology

[0005] The present invention has the following advantages: 1. The use of the upper and lower platforms allows the mine car to enter and exit the double-layer cage at the same time, which solves the problem of the long rest time of the secondary sinking tank and the low lifting efficiency, and greatly improves the lifting efficiency; 2. Due to the use of the upper and lower The two-layer operating platform enters and exits the double-layer cage at the same time. If any part fails, the first layer can still operate normally, so that the impact of the failure on production is relatively reduced, and the production can maintain a relatively stable state; 3. Parking is in place at one time, and the parking position is accurate. The operation is simple and easy to realize automation; 4. It better solves the problem of undertaking the lifting of the upper and lower mine cars, reduces the space and saves a lot of investment

Embodiment Construction

[0010] The wellhead is equipped with a hoisting winch, an upper-level car-operating platform and a lower-level car-operating platform. The hoisting winch is connected to the front and rear cages 8, 29 through wire ropes and connecting devices. The front and rear cages 8, 29 alternate up and down in the mine, and the front cage 8 is in the When loading and unloading at the bottom of the well, the rear cage 29 can be loaded and unloaded just at the well head. The front and rear cages 8, 29 have two levels, each level has two parking spaces for mine cars, and each of the upper and lower floors corresponds to each parking space for mine cars. One minecart rail line and four minecart rail lines are respectively laid on the upper car operating platform 2 and the lower car operating platform 19. Figure 1 shows the structure diagram of the upper and lower car operating platforms installed at the horse head gate at the bottom of the shaft. The front mine car track lines 31 and 32 of the up...

Abstract

The control device for double-layer loading pot in mine shaft has two, one upper and one lower operation platforms with tramway set separately in the shaft top and the shaft bottom, two parking locations separating for the front cage and the rear cage, and one hydraulic height compensator for the upper layer of tramway. The present invention has accurate parking, convenient operation, high hoisting efficiency and high reliability.

Description

(1) Technical field [0001] The invention relates to a mine double-layer loading and unloading tank operating device. (2) Background technology [0002] At present, hoisting of auxiliary shafts in coal mines mostly uses winches, and the hoisting container is a double-deck four-car cage of mine carts. The trucks enter and exit from different sides at the bottom of the wellhead, and the lifting and lowering materials adopt the secondary sinking method for loading and unloading the mine trucks. The use of secondary sunken tanks has the following shortcomings: 1. The use of secondary sunken tanks for loading and unloading mine carts has a long rest time and low lifting efficiency. Generally, it is 40 to 60 seconds longer than the one-time loading and unloading of mine carts, resulting in a relatively shorter effective lifting time. 40~60 seconds; 2. Regardless of the failure of any component of the wellhead or bottom entry and exit vehicle operating device, the lifting system will be ...
