Problems solved by technology

However, there are some problems in this process at present. Due to the long-term use of the hydraulic support in harsh environments, the hinge parts are severely corroded, worn, and deformed, making it impossible to pull out the hinge pins, which restricts the remanufacturing output and capacity of the hydraulic support. Productivity

Embodiment 1

[0036] Such as figure 1 , figure 2 As shown, a pin removal device includes a support base 1, a main action part 2 and an auxiliary action part 3 located above the support base 1, the two sides of the main action part 2 are respectively provided with auxiliary action parts 3, and the The above-mentioned leading action part 2 and auxiliary action part 3 are arranged in antiparallel, reasonable in structure, reliable in operation, and high in safety factor. The work intensity of the operator is reduced, and the work efficiency is high. The sliding wheel 12 is arranged at the bottom of the support base 1, which can realize the position transfer of the whole device and is convenient to move.

[0037] Such as figure 2 , image 3 As shown, one end of the leading action member 2 is provided with a conduit 5, and the other end is provided with a pin fixing member 4, and the pin fixing member 4 is connected with the pin to be removed, and the leading acting member 2 and The auxili...

Embodiment 2

[0041] Such as Figure 1-3 Shown, described a kind of pin removal device in concrete work, comprises the following steps:

[0042] (1) Connect the pin shaft fixing part 4 with the pin shaft to be removed on the equipment, connect the auxiliary action part 3 and the main action part 2 with the driving device, start the driving device, and drive the auxiliary action part 3 to extend, Prompt the auxiliary active part 3 to act on the surface of the equipment, and generate a pulling force F on the pin shaft to be removed 1 , and F 1=P×S, where P is the working pressure of the driving device, and S is the contact area between the auxiliary parts and the surface of the equipment;

[0043] (2) Operate the leading action member 2 and make it in an extended state, drive the grilling hook 8 to move towards the hammer head 9, and under the action of the elastic member 2 13, the grilling hook head 81 will move the groove 91 hooked;

[0044] (3) Operate the leading action member 2 to re...

Embodiment 3

[0049] The same part of this embodiment and embodiment two will not be repeated, the difference is:

[0050] In the underground construction environment, the pin shaft removal device of the present invention is used to remove the pin shaft of the hydraulic support. The service life of the pin shaft to be removed is 5 years, and the driving device is connected to the hydraulic pipeline of the support. No additional driving device is required, and the application value is high.

[0051] The working pressure generated by the hydraulic pipeline of the support is 31.5MPa, and the main action part 2 and the auxiliary action part 3 are both internal liquid-injected jacks with a cylinder diameter of 100mm and a piston stroke of 300mm, then

[0052] f 1 =P×S=31.5×10 6 ×3.14×0.05 2 =247.275KN.

[0053] The diameter d=18mm of the elastic part-6, its rigidity modulus G=7300kN / mm2, its effective number of turns n=9, its maximum compression amount is 250mm, and the length of the slot 11...

Abstract

The invention relates to a pin shaft dismounting device and a using method thereof and belongs to the technical field of dismounting equipment. The pin shaft dismounting device comprises a supporting base, a main acting part and auxiliary acting parts, wherein the main acting part and the auxiliary acting parts are located above the supporting base. The auxiliary acting parts are arranged on the two sides of the main acting part respectively, and the main acting part and the auxiliary acting parts are arranged in opposite directions in parallel. The pin shaft dismounting device has the characteristics of being high in working efficiency and practicality, reasonable in structure, reliable in operation, high in safety coefficient and convenient and rapid to move.

Description

technical field [0001] The invention belongs to the technical field of dismantling equipment, and in particular relates to a pin dismantling device and a using method thereof. Background technique [0002] Due to factors such as the decline in domestic demand and the increase in production and imports, coal prices have continued to decline in recent years, and the ten-year golden period of coal has basically come to an end. The ability to purchase fully mechanized mining equipment in major domestic coal mines has generally declined, and they have gradually adopted the method of repairing and purchasing, which has promoted the development of fully mechanized mining equipment remanufacturing technology. [0003] Remanufacturing is to recycle and disassemble a large number of similar scrapped products, collect and test them according to the type of parts (parts), use scrapped parts with remaining life as remanufactured blanks, and use high-tech to repair them in batches. Perfo...
