[0002] The manipulator is one of the core components of a crawler-type fully automatic drilling rig; it is used to automatically transfer drill rods between the drill rod box and the drilling device, realizing automatic loading and unloading of drill rods in the drilling device and automatic storage and retrieval of drill rods in the drill rod box.

[0003] The telescopic column of the conventional manipulator has the following problems: first, the telescopic column is assembled by an outer telescopic tube, an inner telescopic tube and an oil cylinder, and a guide component is required between the inner and outer telescopic tubes to prevent rotation; this makes the overall structure more complicated and inconvenient to assemble and maintain; second, a displacement sensor is provided between the cylinder barrel and the lower end of the piston rod of the oil cylinder. The replacement of the displacement sensor is labor-intensive and requires disassembly of the oil cylinder. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a telescopic column for a manipulator, which prevents the extension rod from rotating by setting a guide assembly between the column shell and the extension rod; the integrated telescopic column design structure makes the structure of the telescopic column simpler, and the assembly and maintenance are more convenient and quick; at the same time, a displacement sensor is set between the extension rod and the guide rod to facilitate the detection of the extension length of the extension rod.

[0005] The utility model is achieved through the following technical solutions:

[0006] A telescopic column for a manipulator comprises a column housing, an extension rod slidably arranged in the column housing, a detachable column cover arranged at the upper end of the column housing, a piston sleeved on the end of the extension rod extending into the column housing, and a guide assembly arranged between the column housing and the extension rod to prevent the extension rod from rotating.

[0007] Furthermore, the guide assembly includes a guide seat detachably connected to the lower end of the column housing, a guide rod arranged in the guide seat, and a guide sleeve arranged at the lower end of the extension rod.

[0008] Furthermore, the inner cavity of the guide sleeve is provided with a strip-shaped hole; the outer wall of the guide rod is provided with a flat square that matches the strip-shaped hole.

[0009] Furthermore, the lower end of the inner cavity of the extending rod is provided with a connecting hole for connecting the guide sleeve, the upper end is provided with a sensor connecting hole, the middle part is provided with an accommodating hole for accommodating the guide rod, and the outer wall of the upper end of the extending rod is provided with an external thread.

[0010] Furthermore, a displacement sensor for measuring the extension length of the extension rod is provided between the extension rod and the guide assembly.

[0011] The beneficial effects of the present invention are:

[0012] By setting a guide component between the column housing and the extension rod, the extension rod is prevented from rotating; the integrated telescopic column design structure makes the structure of the telescopic column simpler, and the assembly and maintenance are more convenient and quick; at the same time, a displacement sensor is set between the extension rod and the guide rod to facilitate the detection of the extension length of the extension rod.

[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0017] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0018] In the above description of the present invention, it should be noted that the terms "one side" and "the other side" and the like indicate positions or locations based on the positions or locations shown in the accompanying drawings, or the positions or locations in which the product of the present invention is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0019] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.
