Description

Technical Field

[0001] The present invention belongs to the technical field of pin assembly of hydraulic supports, and particularly relates to a pin assembly device for hydraulic supports. Background Art

[0002] Hydraulic supports are key equipment in fully mechanized coal mining faces. Their main components are connected together by pins. The installation quality of the pins directly affects the stability and reliability of the hydraulic supports, and thus is related to the safe production and efficient operation of the entire fully mechanized coal mining face. In the existing pin assembly process of hydraulic supports, the installation method is mostly hoisting. During installation, workers need to lift the pins and insert them into the corresponding pin holes of the pin assembly device of the hydraulic support.

[0003] When installing pins manually, operators need to be in close contact with substances and equipment, which is prone to safety accidents such as heavy object falling and extrusion. At the same time, during the installation process, the pins may be damaged or not installed in place due to improper operation, posing potential safety hazards for subsequent use; moreover, before installing the pins, it is necessary to manually apply lubricating oil to the pins. If the lubricating oil is unevenly applied or insufficient, it will cause increased wear of the pins during use, shorten the service life of the pins and related components, and increase the maintenance cost of the equipment.

[0004] In view of the above problems, this patent proposes a technology that can automatically apply lubricating oil before pin installation and automatically insert the pins into the hydraulic support. This technology can not only improve the automation degree of pin installation, reduce labor intensity and safety risks, but also effectively improve the lubrication effect of the pins by controlling the application amount and application position of the lubricating oil, and extend the service life of the pins and hydraulic supports.

[0057] When the first extrusion plate 6 moves towards the inner wall of the second lifting member 5 under the thrust, the first extrusion plate 6 squeezes the first folding bladder 7, the second folding bladder 10, and the third folding bladder 11. The gas in the first folding bladder 7 is discharged, and the lubricating oil in the second folding bladder 10 enters the lubricating layer 12 through the connecting hole 13 and is discharged through the lubricating hole 14. The control valve in the first ventilation pipe 21 is opened, and the gas in the third folding bladder 11 enters the airbag 20 through the first ventilation pipe 21. The airbag 20 bulges and pushes against the two side walls of the limiting frame 17. The two side walls of the limiting frame 17 rotate away from the side wall of the mounting member 15, and the first insertion rod 19 disengages from the slot hole 18. The control valve in the first ventilation pipe 21 is closed;

[0058] At the same time, the second extrusion plate 16 slides along the inner wall of the mounting member 15, the first spring 28 is compressed, the second insertion rod 27 is arranged in the limiting hole 25, and the second spring 26 is compressed. When the second extrusion plate 16 moves to the position of the slot hole 18, the second spring 26 pushes the second insertion rod 27 into the slot hole 18. At this time, the upper end of the second lifting member 5 disengages from the sliding belt 31 and is arranged at the hydraulic support. As the second lifting member 5 continues to lift, under the action of the sliding belt 31, the first extrusion plate 6 remains in a compressed state and is arranged close to the hydraulic support;

[0059] After the second lifting member 5 moves to the position where the pin shaft 38 needs to be installed, the gas in the airbag 20 is discharged. Under the action of the torsion spring, the two side walls of the limiting frame 17 return to the initial position, the first insertion rod 19 is inserted into the slot hole 18, and the second insertion rod 27 is squeezed. The first insertion rod 19 retracts into the limiting hole 25, and the first spring 28 pushes the second extrusion plate 16 to move quickly outwards. The second extrusion plate 16 pushes the pin shaft 38 and pushes the pin shaft 38 into the installation hole where it needs to be installed;

[0060] Then the motor 43 works in the reverse direction, driving the connecting roller 45 to rotate. The connecting roller 45 drives the first lifting member 4 and the second lifting member 5 to descend synchronously. When the first extrusion plate 6 and the connecting plate 22 move to the position of the sliding belt 31, as the second lifting member 5 continues to move downwards, the third spring 9 pushes the first extrusion plate 6 to move outwards. The first extrusion plate 6 drives the first folding bladder 7, the second folding bladder 10, and the third folding bladder 11 to stretch. External gas enters the first folding bladder 7. At the same time, the lubricating oil in the storage barrel 33 enters the second folding bladder 10 through the first connecting pipe 34, and external gas enters the third folding bladder 11 through the one-way valve;

[0061] When the first lifting member 4 moves downward, it can squeeze the fourth folding bladder 39. The control valve on the fourth folding bladder 39 opens, and the gas is discharged. As the fourth folding bladder 39 continues to move downward, the control valve closes, and the control valve in the second connecting pipe 41 opens. The gas in the fourth folding bladder 39 enters the elastic bladder 36 through the second connecting pipe 41. The elastic bladder 36 bulges to drive the pushing plate 37, and the pushing plate 37 drives the pin shaft 38. The outermost pin shaft 38 moves to the side wall of the first lifting member 4. When the first lifting member 4 and the second lifting member 5 return to the initial position, the outermost pin shaft 38 of the fixing member 3 rolls from the fixing member 3 to the first lifting member 4 and then rolls to the second lifting member 5 and is clamped in the limit buckle 24. During the rolling process, the lubricating oil emerging from the lubricating hole 14 on the upper wall of the second lifting member 5 adheres to the pin shaft 38, facilitating the installation of the pin shaft 38. Then, the above steps can be followed for installation.
