Problems solved by technology

For the underwater manipulator used by the strong operation type underwater robot, due to the increase of the weight capacity, the telescopic distance increases. When the telescopic arm is fully extended, if the above structure is still used, due to the large eccentric force, it will cause telescopic Sleeve does not retract

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings.

[0022] Such as figure 1 , 2 , 3, 4-1, and 4-2, the telescopic joint of the underwater manipulator of the strong operation type underwater robot of the present invention mainly includes a telescopic arm 1, a guide square sleeve, and a telescopic oil cylinder 4 in structure, wherein:

[0023] The telescopic arm 1 is a hollow rectangular cylinder with a first-class wall thickness, and its section is rectangular (the upper and lower sides are longer than the front and rear sides). There are connecting holes on the four sides of the cylinder at one end of the telescopic arm 1, which are connected to the front joint by screws to drive the front joint to perform telescopic movement; at the corners of the four edges of the cylinder at the other end of the telescopic arm 1, along the A right-angled short groove is processed for placing the rear corne...

Abstract

The invention discloses a strong-operation underwater manipulator telescopic joint used for an underwater robot, comprising a telescopic arm, a guide square sleeve and a telescopic oil cylinder; the telescopic arm is a hollow rectangle podetium with uniform wall thickness and rectangle section; the podetium at one end of the telescopic arm is connected with a front joint, which is used for driving the front joint to carry out telescopic motion; at the vertex angle of the four edges of the podetium at the other end of the telescopic arm, right angle-shaped troughs are arranged along the edges and used for placing a rear angle supporting; the guide square sleeve is composed of a front baffle, a rear baffle, an upper baffle and a lower baffle and is sheathed on the external surface of the telescopic arm; the telescopic oil cylinder is arranged in the chamber of the telescopic arm; the centre of the telescopic oil cylinder is in the same lead vertical plane with the centre of the telescopic arm; the telescopic arm is connected with a rear supporting shaft and a front supporting shaft which is used for supporting the telescopic oil cylinder. The invention is the underwater manipulator telescopic joint which can be applied to strong-operation underwater robots and has the advantages of great bearing capacity, long telescopic length, light weight and simple structure.

Description

technical field [0001] The invention relates to an underwater manipulator, in particular to an underwater manipulator telescopic joint of a strong operation type underwater robot. Background technique [0002] At present, the development and utilization of the ocean by human beings has been rapidly developed, and the number of ocean engineering involved is increasing day by day. Underwater robots with operating functions have been widely used. The operating tasks of the underwater robot are mainly completed by the underwater manipulator and special underwater tools it carries. In order to effectively perform a variety of underwater operations, underwater manipulators should generally have 4 or 6 degrees of freedom and an additional clamping function. Most of the 5-function underwater manipulators have telescopic degrees of freedom. In the prior art, the expansion and contraction of the manipulator is realized by using a linear hydraulic cylinder to drive a cylindrical tele...
