High-sealed, high-strength, high-temperature-resistant sword-type manipulator

Abstract

The invention discloses a high-seal, high-strength and high-temperature-resistant sword type mechanical arm which comprises a clamp, a hand lever, a pull rod, an outer tube, a handle and a sealing joint; clamping fingers of the clamp are stainless steel clamping fingers, and the surfaces of the inner sides of the clamping fingers are provided with anti-slip stripes; the sealing joint comprises a shell, a sealing sleeve, a sealing ring, an ejector rod and a spring, the two ends of the shell of the sealing joint are in sealing connection with a pressing ring of the clamp and the outer tube, and the two ends of the ejector rod of the sealing joint are connected with a movable rod of the clamp and the hand lever respectively. According to the high-seal, high-strength and high-temperature-resistant sword type mechanical arm, the surfaces of the inner sides of the clamping fingers are provided with the anti-slip stripes, friction force in the object clamping process is increased, and quality accidents caused by sliding and falling of objects in the operation process are avoided; the sealing joint is additionally arranged, the ejector rod in the mechanical arm and the shell are separated and sealed through the sealing sleeve, therefore, the movable rod of the clamp, the ejector rod of the sealing joint and the hand lever are all in separated sealing with the outside, and the requirements for a high-seal, high-strength and high-temperature-resistant hot chamber are achieved as a whole.

Description

technical field [0001] The invention relates to a sword-type manipulator, in particular to a sword-type manipulator with high sealing, high strength and high temperature resistance. Background technique [0002] The sword-type manipulator is a hand-operated tool, and its function is to cooperate with the ball joint bearing. It is used in the shielding box of the nuclear industry (such as isotope production), pharmaceutical, medical and other industries to separate the radioactive substances that cannot be directly touched by human hands. It has the characteristics of compact structure, simple operation, and easy to master basic operating techniques. [0003] Such as figure 1 and figure 2 As shown, the traditional sword-type manipulator is mainly composed of clamp 7, handle bar 6, pull rod 12, outer tube 14, handle 13, etc., and the handle bar 6 and pull bar 12 are all placed in the outer tube 14, and one end of the outer tube 14 It is connected with the pressure ring 75 ...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned traditional sword-type manipulator can only be used in an environment with low sealing requirements, because there is a gap between the outer tube of the clamp 7 of the sword-type manipulator and the handle bar 6, so the seal is not thorough enough. In addition, the sword-type manipulator The clamp finger 72 of the clamp 7 has a rubber sleeve 73 for anti-skid, which cannot withstand high temperature and the rubber is easy to age, which may lead to insufficient stability when picking up objects, and the rubber sleeve 73 also causes the thickness of the clamp finger 72 to be thinner and stronger. low, less rigid
