Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing:

[0033] figure 1 , 2 . As shown in 3, it is the overall structure diagram. The position and connection relationship of each part must be correct and the installation should be firm.

[0034] All hydraulic valves and hydraulic pipes must be unblocked, and the force gauge must be accurate.

[0035] The hydraulic cylinder and the piston rod of the hydraulic cylinder should be flexible.

[0036] The pressure of the high-pressure pump and hand lever should be normal and the operation should be flexible.

[0037] The force gauge should be displayed correctly, and it should be displayed directly in kilograms.

[0038] Figure 4 , 5 As shown, it is the structural diagram of the chain block. The chain block should have good strength and high hardness, and should be made of alloy tool steel and hardened.

Abstract

The invention relates to a device for measuring the tension of a scraper conveyer chain, mainly comprising a high-pressure pump, a hand compression rod, an unloading valve, a stop valve, a tension meter, a blocking chain block, a telescopic oil cylinder and an oil cylinder piston rod. With the combination of the hydraulic drive, the tension meter and the blocking chain block of the device for measuring the tension of the scraper conveyer chain, the tension of the scraper conveyer chain under the coal mine is measured immediately on the spot, the measured pretension and the static tension are contrasted, compared and are optimized to finally determine the reasonable pretension and the reasonable static tension, the tensioning degree of the scraper conveyer chain is guided and debugged with the pretension and the advantage and the disadvantages of tensioning state of the scraper conveyer chain are appraised with the static tension so that the scraper conveyer chain can be in the reasonable tensioning state to suffer from less accident and have long service life. The device has reasonable and advanced design, compact structure, convenient carrying, mounting and detecting and is safe, stable and reliable, thereby being very ideal.

Description

technical field [0001] The invention relates to a tension force measuring device for a chain of a scraper conveyor, belonging to the technical field of measuring devices and methods for parts of coal mine transportation equipment. Background technique [0002] The scraper conveyor is the transportation equipment of the coal mining face in the coal mine. The tension of its transmission chain is very important to the normal operation of the scraper conveyor; These forms show that excessive chain tension will not only aggravate the meshing wear between the chain and the sprocket, but also lead to an increase in power loss. Chain, stuck chain, broken chain, broken scraper and other accidents account for more than half of all faults. Therefore, it is very important to measure the tension of the transmission chain. [0003] At present, the measurement of the chain tension force of the scraper conveyor is still in the theoretical research stage, and the theoretical value of the ch...
