Abstract
The utility model relates to an adjustable back inclination prevention device for a spring tube structure of a crawler crane, which comprises an inner tube. The outside of the inner tube is sleeved with an outer tube. The upper end of the inner tube extends out of the outside of the outer tube and is connected with an upper connection plate. The upper connection plate is provided with a hole through which an upper connecting shaft passes. The inner tube is sleeved with a spring. One end of the spring is pressed against a step of the upper end head of the inner tube, while the other end thereof is pressed against the upper end head of the outer tube. The side wall of the outer tube is provided with an outer tube slot hole. The outer tube is provided with a travel switch by a mounting plate. A rotating arm of the travel switch extends into the inside of the outer tube from the outer tube slot hole. The adjustable back inclination prevention device for the spring tube structure of the crawler crane has the advantages of accurate back inclination detection of an arm support, flexible and reliable movement, good capability of regulating the detected elevation range in a wider range, small drifting and high regulation accuracy.
Description
Technical field
The utility model relates to a kind of crawler crane spring tube Adjustable structure formula anti-squat system that is used for.
Background technology
The device that is used for the anti-hypsokinesis of crawler crane at present is to join the weldering detector switch and detect adapter plate with jib joint portion and jib root at the turntable of hoisting crane to prevent the jib hypsokinesis, reports to the police when hypsokinesis and stops upwards that luffing moves.Weldering is joined at installation and measuring switch and the check-out console scene of all adopting, and the human element influence is bigger, and it is very little that adjusting accuracy is installed.Because long-time the use causes the wearing and tearing of machinery can cause drift, can not guarantee the accurate location of maximum elevation in addition, and the scene joins weldering and easily cause corrosion, influence the outward appearance of product.
Summary of the invention
That the purpose of this utility model provides that a kind of jib hypsokinesis detects accurately, flexible movements are reliable, elevation coverage that detect can be adjusted in the larger context, drift about is little, adjusting accuracy is high is used for crawler crane spring tube Adjustable structure formula anti-squat system, overcomes the deficiencies in the prior art.
The crawler crane spring tube Adjustable structure formula anti-squat system that is used for of the present utility model comprises interior pipe, is set with outer tube in the outside of interior pipe, and the upper end of interior pipe is stretched out the outside of outer tube and is connected to upper junction plate, and upper junction plate is provided with the hole that penetrates adapter shaft; Be with spring on inner pipe, an end of spring leans on the step of termination on inner pipe, and the other end of spring leans on the upper end of outer tube; Be processed with the outer tube slotted hole on the sidewall of outer tube, by adapter plate travel switch be installed on the outer tube, the pivoted arm of travel switch stretches into the inboard of outer tube from the outer tube slotted hole, and the inner termination of interior pipe and the roller on the pivoted arm match; Head connects lower connecting plate in the bottom of outer tube, and the hole that penetrates down adapter shaft is arranged on the lower connecting plate.
The crawler crane spring tube Adjustable structure formula anti-squat system that is used for of the present utility model, during installation, can the upper junction plate and last adapter shaft and the crane arm support that be positioned at the top is hinged, the lower connecting plate that is positioned at the below is hinged with the rotating disk of following adapter shaft and hoisting crane, travel switch joins with the electrical controller that the control jib lifts, during operation, jib upwards rotates the elevation angle and becomes in the big process, spring is compressed, interior pipe moves in outer tube, and the inner termination way roller place of interior pipe is close, when the elevation angle reaches some regularly, the inner termination of interior pipe touches roller, stops jib by the travel switch action and lifts.Flexible movements are reliable, and the jib hypsokinesis detects accurately, because adjustable positions is put in order between travel switch and its adapter plate, so can adjust the detection range at the jib elevation angle, it is little to drift about, and the adjusting accuracy height has overcome that field welding easily produces the phenomenon of corrosion in the prior art.
