Problems solved by technology

[0003] However, in this technology, the length of the screw rod is long, and it is necessary to use the bolt to hold it and then screw it in with a wrench during installation, which is time-consuming and laborious to install.
[0004] When pulling out longer pins, the stroke of the jack is often not enough, and it needs to be adjusted and added pads or rotating nuts, which is inefficient when used

Embodiment Construction

[0025] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as Figure 1 to Figure 6 As shown, an adjustable stop pin removal structure 100 includes: a pin pulling rod 10 , a jack 20 and a screw head 30 . The screw head 30 is used for screwing into the threaded hole of the stop pin to form a connection with the stop pin. The jack 20 includes: a pressing plate 21 and a hydraulic cylinder 22 . The pin pulling rod 10 is connected to the screw head 30 . The pressing plate 21 slides relative to the hydraulic cylinder 22 to drive the pin pulling rod 10 to move.

[0027] The adjustable stop pin removal structure 100 further includes: a positioning rod 40 . The positioning rod 40 is used for fixing the relative position of the pin pulling rod 10 and the pressing plate 21 . The positioning rod 40 is movably connected to the pressing plate 21 . The pin pulling lever 10 is formed with a plu...

Abstract

The invention discloses an adjustable stop pin detachment structure. The adjustable stop pin detachment structure comprises a pin pulling rod, a jack and a screw head used for being screwed into a thread hole of a stop pin; the jack comprises a press plate and a hydraulic cylinder; the pin pulling rod is connected to the screw head; and the press plate slides relative to the hydraulic cylinder todrive the pin pulling rod to move. The adjustable stop pin detachment structure further comprises a location rod used for fixing the relative positions of the pin pulling rod and the press plate. Theadjustable stop pin detachment structure has the beneficial effects of being capable of realizing a high pin pulling stroke, convenient to use, and high in efficiency.

Description

technical field [0001] The invention relates to a stop pin removal structure, in particular to an adjustable stop pin removal structure. Background technique [0002] The traditional stop pin removal structure is to combine bolts, screw rods and jacks, screw the screw rods into the pins, install the jacks and lock them with bolts, and push the bolts through the jacks to bring out the pins. [0003] However, in this technology, the length of the screw rod is relatively long, and it is necessary to use bolts to hug each other and then screw them in with a wrench during installation, which takes time and effort for installation. [0004] When pulling out longer pins, the jack often has insufficient travel, and needs to be adjusted and added pads or rotating nuts, which is inefficient during use. Contents of the invention [0005] The invention provides an adjustable stop pin removal structure, which adopts the following technical scheme: [0006] An adjustable stop pin remo...
