Abstract
The invention relates to a twistlock for lifting equipment, designed to engage with the corners of containers, comprising a fulcrum pin, a tracer pin and actuation elements, such as levers, and elements that recognize the twistlock position, such as sensors. Said twistlock pin (16), with its elements (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16), forms a modular unit that can be quickly assembled and disassembled. The elements are fastened in openings of the spreader (15) by means of fastening elements (8, 10) in a detachable and anti-twist manner. Once the locking element (8) is released and the pin linking the lever (9) for the twistlock engagement with a corresponding actuation element, every twistlock can be immediately removed and exchanged.
Description
Technical field
The present invention relates to a kind of twist lock elevator, interlocking freight container each angle that is used for, comprise ship and resell on another market, probing pin and operating unit and judge the parts that the twist lock position is used.
Background technology
Twist lock of the present invention hangs on the frame to being installed in, all twist locks that must often change and need to install and remove time and materials all are suitable for owing to wearing and tearing.
Outstanding frame is used for one or more container fixing at elevator, wherein outstanding frame hold vehicle one or more freight containers, one or more container loadings are stacked in the warehouse on vehicle or with one or more freight containers.For container fixing is utilized four twist lock pins usually on outstanding frame.
Freight container all has so-called twist lock at each angle to be fixed.This twist lock fixedly has a long hole shape opening, wherein can embed the twist lock pin.Rotating 90 ° by the twist lock pin makes the twist lock lock due to the twist lock fixed position.Being dimensioned to of outstanding frame makes the twist lock pin that protrudes from outstanding frame be suitable for twist lock in distance and fixes.For the application of different Container Dimensions, outstanding frame is equipped with telescopic mounting.Four all twist lock pins are at each angle of freight container respectively and embed the twist lock fixed position above the freight container when loading onto outstanding frame.To hang that frame installs on the freight container and when the twist lock pin inserts the twist lock fixed position, insert near the probing pin that is located immediately at respectively the twist lock pin.The first twist lock pin has a probing pin respectively.When having inserted the probing pin of installing there fully for all four jiaos, can at first provide and be used to rotate the twist lock pin to throw off and the signal of locking.The position of each probing pin can be detected separately by contactless terminal switch.The torque that is used to lock and throws off the twist lock pin can selectively be applied to the twist lock pin by means of a hydraulic actuating cylinder.
By DE-OS 2940116 known a kind of outstanding frames that freight container is used that are used for, its twist lock is operated in such a way.In case each failsafety or wearing and tearing on the twist lock of outstanding frame, its consequence are equipment malfunctioning that causes whole outstanding frame or make its motion.
By the known a kind of outstanding frame that comprises twist lock that is used to have the freight container of angle backplate of DE-OS 19632181, wherein different twist lock member is arranged on the base plate on outstanding frame.The shortcoming of same this device is, when the single parts of want of repair twist lock, whole outstanding frame is at the repair time withdraw from use, thereby causes thus very long standing time.
Summary of the invention
Therefore the objective of the invention is, develop a kind of device, can realize: to hang the less down time of frame to each twist lock place under repair and handling labor by it.
For achieving the above object, the invention provides a kind of elevator of being used for, the twist lock at each angle of interlocking freight container, comprise and shipping and reselling on another market, the sensor that probing pin and operating lever and judgement twist lock position are used, it is characterized in that, the Modular units that each component set-up of twist lock pin and its is quickly assembled and disassembled, described parts comprise the twist lock nut, locking disk, the twist lock guide plate, probing pin, the probing pin protective plate, the probing pin spring, the twist lock cover, the tenon piece, twist lock rotates the lever of usefulness, the anti-rotation device of twist lock cover, be used for correctly inserting the sensor of probing pin, be used for the sensor that twist lock is in a disengaged position, be used for the sensor that twist lock is in latched position, be used to connect the multipole quick adapter of sensor, wherein, detachable and anti-commentaries on classics ground is fixed in the hole of outstanding frame by means of its retaining element in described unit; Wherein, described anti-rotation device is arranged on a side of twist lock in the following manner, that is, the twist lock cover is fixed on the twist lock unit on the related parts that hangs on the frame by means of the face of the arc section of a cutting.
The solution of the present invention relates to a kind of twist lock that is used for elevator, and wherein, twist lock pin and its each parts are designed to detachable Modular units, its detachable and anti-being fixed on the outstanding frame with changeing.Its prerequisite is, all belong to the unit of a compactness of component set-up of twist lock, and it has cylindrical shape and can be used as such unit and inserts in the corresponding opening on the outstanding frame.The lever of twist lock pin and twist lock nut, locking disk, twist lock guide plate, twist lock rotation usefulness, anti-rotation device, each sensor of determining the twist lock position and a sensor of twist lock cover are connected the quick adapter of usefulness and can be arranged to make it can simply and quickly insert in the cylindrical hole that hangs on the frame in a cylinder or on it.Advantageously the twist lock Analysis of Nested Design is become to make its part towards freight container have less diameter than the part above it for this reason, hang on the frame so that top part is supported on outstanding frame and with the weight of twist lock unit and load to be transported as edge bearing.Part below detouchable twist lock unit realize a twist lock safety lock in case its from outstanding frame, pull out.
This can so advantageously reach, that is, the twist lock guide plate that makes the lock pin that can rotate constitute a dish on every side has a groove at its excircle, wherein embeds the joint tongue of a tenon piece.
The tenon piece can be designed to the ring of subdivision, its can from following with screw-driving to outstanding frame.
The joint tongue of tenon piece can have different shape and can be in the centre of ring, also can be at an upper portion thereof or the bottom be arranged on the ring.
The upper part diameter of twist lock unit only partly designs conglobate, so that its no arc section can stick into the related parts of outstanding frame.
Locking disk is ball-shaped in its underpart.The twist lock pin is rotatable whereby reaches 0.5 °.
The position of each probing pin is detected separately by contactless terminal switch.
Probing pin is arranged on the inside of the cylindrical profile of each twist lock unit.
The advantage of the solution of the present invention is, the twist lock unit is after pulling down the tenon piece and pulling down pin, and the lever that the latter rotates twist lock usefulness is connected with a corresponding executive component, just can take out the also replacing of each twist lock immediately, and quick adapter unclamps a sensor.Can beyond outstanding frame, carry out the repair and maintenance work on the single twist lock, thereby have only the very little loss of time.
In addition, fast speed insertion and safety particularly realize by anti-rotation device by the top part of twist lock.Because each sensor is positioned at the inside of twist lock unit, it prevents the damage that caused by atmospheric influence, pollution and mechanical damage to the full extent.
Also advantageously, be used to judge the sensor of the position of probing pin.Also advantageously, this sensor can be changed with the twist lock unit.
Because this sensor and twist lock unit are integral formation, it prevents dust and corrosion.The bothersome calibration and the work of adjusting have been eliminated by means of anti-rotation device and shape locking mode.
