Abstract

The invention discloses an oil cylinder rod stretching length limiting device which comprises a first installation body, a first connection rod, a second connection rod and a second installation body. The first installation body and the second installation body sleeve an oil cylinder rod. The inner diameter of the first installation body and the second installation body is smaller than the outer diameter of the cylinder body. The first installation body and the second installation body are both formed by detachably connecting two assembly bodies. A through hole with inner threads is formed in each assembly body. The first connection rod and the second connection rod have outer threads. The first connection rod and the second connection rod are in threaded connection with the first installation body and the second installation body. Due to the fact that the first connection rod and the second connection rod are connected between the first installation body and the second installation body through threads, the distance between the first installation body and the second installation body is adjustable, and the technical problem of poor generality of the existing oil cylinder rod stretching length limiting device is further solved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a device for limiting the telescopic length of an oil cylinder rod. Background technique [0002] During the operation of construction machinery vehicles, hydraulic cylinders are usually involved. Taking the rail grinding operation as an example, the grinding trolley used for grinding the rail is hung under the railway rail grinding vehicle through four hydraulic cylinders. During the grinding operation, the hydraulic oil cylinder is in an extended state to make the grinding trolley contact the rail, thereby realizing the grinding operation of the grinding trolley on the rail. During the non-grinding operation, the hydraulic cylinder is in contracted state to separate the grinding trolley from the rail, and the degree of contraction of the cylinder rod of the hydraulic cylinder is usually limited by a limit device. [0003] as attached figure 1 As shown, the existing limitin...
