Partial loading (including side and back) is likely to cause road rollover or rollover accidents in sharp bends. These two phenomena will accelerate the abnormal wear of the tires. The driver's supervision of the electric excavator driver, as long as the partial installation behavior is found, the driver of the cart immediately reports the on-site dispatch and evaluates his behavior. In another case, due to the imbalance of hydraulic damping on both sides of the vehicle, the bucket itself is inclined, and the partial installation is easy to occur. At this time, the damping cylinder pressure should be stopped immediately. Strengthen the formulation of vehicle speed management (standards for the operation of cart drivers) and (the standard for the production of mining mines), clearly stipulate the driving speed of vehicles in different routes and places, and the drivers of the carts must be strictly implemented. The speed management inspection team is set up regularly, and regular inspections are conducted. Random inspection, found that the speeding immediately gave the post to be treated. Strengthen the road maintenance work, establish the idea of ​​"culturing the road, repairing the car", strengthen the road level management from the source. Grab the perforation process; grasp the shovel loading process, require the electric excavator driver Timely clearing the bottom to ensure that the loading point of the cart is kept smooth at the same time. At the same time, the mining process manager manages the operation of the electric excavator daily to prevent the bottom plate from being over-excavated and under-excavated by an electric excavator. Shaped roads cause frequent turning of vehicles and accelerate tire wear. In order to avoid the formation of S-shaped roads in the stope, the following work must be done: the stripping work line must be balanced and developed straight, and the number of large blocks >10 must be treated by two explosions; The field high-voltage line layout must be horizontal and vertical, and the electric excavator and rig cable should be laid out reasonably. If necessary, it can be erected. The power supply line is used for the main equipment to ensure that the moving line of the stope is straight; the unloading point ensures sufficient return length, generally >25m, when the double-bar stop is set at the slipway, it must be arranged in the shape of inverted "eight"; strengthen the road Maintenance work to keep the road smooth. The rock in the south of the stope is weathered and oxidized seriously, containing large soil, and the rainy season is easy to form a soft or seesaw road. Before the rainy season, pre-padded a layer of moderate rock to keep the road hard; Must meet the process standard, the trunk line is 11m, there is no deep pit on the road surface, otherwise the parking will be repaired, and a professional maintenance team will be set up to clean the pavement pumice.
Scrap or cut more than two scrapping tread rubber peeling separation (tread tread rubber peeling or tread rubber ply separation such as expansion of the tire throughout the week, scrap rubber from the curtain slightly swelled to swell part of the air and continue to separate the layer For severe swelling, after the separation part is removed, the slight swelling can be repaired and the abnormal wear and tear of the scrap can be repaired or the position change can be checked. The air pressure and the load tread center and the part of the tire are sharply worn to check the local wear of the air pressure and the load, and the polygon wear check brake, Wheel, and wheel shoulder wear alignment check wheel alignment crack shallow crack continue to use the appropriate air pressure blasting due to impact or splitting blasting scrapping smooth wear evenly, no trauma or swelling tread retread tread flower shoulder The block improves the road conditions, and the tires are replaced by the block. On the rough road, there are 5 shaft wells and 7 auxiliary shaft winches in the bureau. Both use the CYS or CY type bottom cradle.
The spring-buffered receiving device is a new type of lifting cage receiving device designed with a strong spring as a cushioning component. The device has the advantages of a cradle and a can, and avoids the disadvantages of both. Therefore, it has the accurate bearing position, convenient access to the mine car, and has a strong buffering receiving function, which slows down the impact force and has less impact on the cages, the loaded articles in the tank and the wellbore equipment. When the lifting cage is operated at high speed, the lifting cage can be safely protected by the receiving device; when the parking position error is large due to the depth of the well and the load change, the equipment can be effectively and accurately received, avoiding duplication. For the tank, the lifting efficiency is improved and the safe operation is ensured.
