Description

Mining chain block testing arrangement

Technical Field

The utility model relates to a mining chain block testing device which can simply test the rated tension of a chain block after the chain block is maintained.

Background

China is the world with the largest coal yield, and the whole coal production technology is at the leading level. The coal mining modes mainly include open-pit mining and underground mining. Because of the limitation of coal occurrence conditions, most coal mines in China adopt an underground mining mode, and before coal mining, a mining, excavating, mechanical, transporting and communicating system needs to be formed to complete the installation and debugging work of various devices. In the process, due to the limitation of the underground operation space, the chain block is often used for hoisting operation. The chain block is also called a chain block, is suitable for short-distance hoisting of small equipment and goods, the hoisting weight is generally not more than 10T, and the hoisting height is generally not more than 6 m. It has the characteristics of simple and convenient operation, small tension of the bracelet, small overall dimension, light self weight, convenient carrying and the like. Due to the fact that underground space of a coal mine is narrow and small and environment conditions are severe, the chain block is often damaged when used and needs to be lifted in a well for maintenance and reuse, and the main requirement after maintenance is that the hoisting rated weight index can be achieved. At present, after maintenance, workers simply pull the chain to bear the stress, try to test the reliable tension condition, display that the hoisting rated tension is used, and cannot absolutely meet the on-site safety production, and the defects of potential safety hazards and the like exist to a certain degree.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a testing device for a mining chain block, which can detect the rated tension of the repaired chain block, is convenient to know the condition of the rated tension, is simple to operate and can improve the safety and reliability of the repaired chain block.

In order to achieve the above object, the present invention comprises: the landing leg, the chassis, the stiffener, a fixed base, the pneumatic cylinder, the hydraulic pressure table, the pull ring, the regulating plate, the round pin axle, fixed frame, the fixed landing leg that is provided with in chassis both sides lower part, the fixed fixing base that is provided with in chassis left side upper portion, move towards the fixed pneumatic cylinder that is provided with of level along the chassis in the fixing base, pneumatic cylinder upper portion is provided with the hydraulic pressure table, the piston end of pneumatic cylinder is connected with the pull ring, fixed frame that is provided with in the right-hand member upper portion of chassis, it has the round hole to open in the middle of the upper portion of fixed frame, wear the regulating plate in the middle of fixed frame, it has one row to draw the hole to open on the regulating plate, the round hole is followed in proper order to the round pin axle, draw the hole to insert and block the regulating plate inside fixed frame.

And a reinforcing rod is fixedly connected between the two side supporting legs at the lower part of the underframe.

When the chain block is used, the repaired chain block is placed on the testing device, the upper lifting hook is hung in the pull ring at the left end, the lower lifting hook is hung in the pull ring at the end of the adjusting plate, the adjusting plate is adjusted towards the right side, after the lifting chain is tensioned, the adjusting plate is clamped inside the fixing frame by inserting the pin shaft from the round hole and the pull hole in sequence, and the testing is started after the completion. The pulling hand chain makes the sprocket clockwise rotation, and the jack-up chain axle is also followed rotatory, makes the jack-up chain begin to contract more and more tightly, and the pull ring drives pneumatic cylinder piston end and removes slowly, and hydraulic pressure table pointer constantly rises simultaneously, stops the pulling hand chain when waiting to reach test rated tension lifting value, pressurize 30 minutes, and pressure normally does not glide promptly and regards as qualified. The method is simple to use and convenient to operate, can know the rated tension condition of the repaired chain block, ensures the use safety and meets the production requirement under the coal mine.
