Thereby achieving the technical effect of conveniently disassembling the shock absorber 100 and reducing the maintenance cost.
In order to explain the installation and operation of the damper removing apparatus according to the embodiment of the present invention in detail, the following steps will be provided for a detailed explanation:
in the first step, on the structural member 200 of the vibration damping device, guide holes (e.g., the first guide hole 211, the second guide hole 212, the third guide hole 221 and the fourth guide hole 222) are formed according to the number and diameter of the pressure rods (e.g., the first pressure rod 530 and the second pressure rod 540), and the guide holes are projected into the upper surface of the vibration damping device 100 (the guide holes may be reserved in designing the vibration damping device).
Second, the damper 100 and the structural member 200, and the fixing bolts on the structural member 200 and the base 300 are loosened.
Third, selecting a proper length of pressure bars (e.g., the first pressure bar 530 and the second pressure bar 540), and fixing the pressure bars (e.g., the first pressure bar 530 and the second pressure bar 540) on the platen 520; and are correspondingly inserted into the guide holes (e.g., the first guide hole 211, the second guide hole 212, the third guide hole 221, and the fourth guide hole 222) formed in the damper structural member 200.
Fourth, the hydraulic head 610, the hydraulic pipe 630 and the hydraulic pump 620 are connected to each other while the hydraulic head 610 is adjusted to a state of the lowest height, and the hydraulic head 610 is placed at the center of the pressing plate 520.
Fifth, the pressing plate 520 is fixed to the structural member 200 of the vibration damping device by the fixing bolts.
Sixth, the hydraulic head 610 is pressurized by the hydraulic pump 620 such that the hydraulic head 610 is raised. Since the cover 510 is in a fixed position, the cover 510 cannot be moved. In turn, pressure is applied to the platen 520, and the platen 520 causes the pressure rods (e.g., the first pressure rod 530 and the second pressure rod 540) to apply pressure to the shock absorber 100, so that the shock absorber 100 compresses (e.g., the distance between the first plate surface 110 and the second plate surface 120 decreases) when receiving the pressure.
Seventh, when the shock absorber 100 is compressed to be in a state of being separated from the structural member 200, the height locking means (e.g., the first height locking member 410 and the second height locking member 420) is fixed to the lower plate (e.g., the first plate surface 110) of the shock absorber 100 by the locking bolts. The height of shock absorber 100 is then limited to the compressed height by adjusting the height locking devices (e.g., first height locking member 410 and second height locking member 420).
Eighth, when the hydraulic pump 620 is depressurized and the pressure rods (e.g., the first pressure rod 530 and the second pressure rod 540) and the shock absorber 100 have no force therebetween, the shock absorber 100 can be pulled out from the lower side of the structural member 200, and at this time, the shock absorber 100 can be disassembled. Thereby achieving the technical effect of conveniently disassembling the shock absorber 100 and reducing the maintenance cost.
The invention provides a detachable limiting device for a shock absorber, which is characterized in that a base 300 is detachably connected with a second plate surface 120 of the shock absorber 100, a first end 411 of a first height locking piece 410 in a limiting mechanism 400 is detachably connected with a first plate surface 110 of the shock absorber 100, and a second end 412 of the first height locking piece 410 is detachably connected with the second plate surface 120 of the shock absorber 100; the third end 421 of the second height locking member 420 of the limiting mechanism 400 is detachably connected with the first plate surface 110 of the shock absorber 100, and the fourth end 422 of the second height locking member 420 is detachably connected with the second plate surface 120 of the shock absorber 100, so that the first body 130 of the shock absorber 100 is located between the first middle section 413 of the first height locking member 410 and the second middle section 423 of the second height locking member 420. If it is desired to disassemble the shock absorber 100, the shock absorber 100 and the structural member 200 are separated by the stopper mechanism 400 and the shock absorber 100 can be withdrawn. Thereby achieving the purposes of conveniently disassembling the shock absorber 100, conveniently separating the shock absorber 100 and the structural member 200 from each other, and reducing the maintenance cost. Thereby achieving the technical effects of conveniently separating the shock absorber 100 from the structural member 200, conveniently disassembling the shock absorber 100 and reducing the maintenance cost.
Finally, it should be noted that the above-mentioned embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications and equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and all such modifications and equivalents are intended to be encompassed in the scope of the claims of the present invention.
