Description

Weight self-balancing anti-drop gets electric installation

Technical Field

The utility model relates to a wiping line equipment technical field, especially a weight self-balancing anti-drop get electric installation.

Background

When the portal crane is used for transferring goods, the equipment which is used for transferring on the portal crane needs to change positions continuously, and in each different position, the equipment can obtain a power supply at any time, otherwise, the equipment cannot move continuously. On the gantry crane, a plurality of conductors are laid in parallel along the running track of the equipment and are connected with a power supply, and a current collector capable of taking electricity from the conductors is arranged on the equipment, so that when the equipment moves, the current collector runs synchronously with the equipment and takes the power supply from the conductors at any time, so that the equipment can continue to move, and the device formed by the conductors and the current collector is called a trolley line.

At present, the existing electricity taking device adopts a four-connecting-rod type, a spring is utilized to obliquely pull to enable a sliding knife to generate upward pressing force to take electricity from a sliding groove wire, so that the height difference in the installation process of a sliding contact line is adapted, the left and right errors of the sliding contact line and the sidewise bending of a cart track are automatically adjusted and adapted through a double-hinge device, the scheme has the defects of adaptability and reliability, the sliding knife is frequently separated from the sliding contact line to be damaged, the power failure maintenance is frequently needed, the normal operation cannot be carried out on a gantry crane, the primary problems that the transportation production is influenced and the like exist, and the following technical defects exist: (1) the depth of a sliding groove of the safety sliding contact line is less than 10mm, the width of the sliding groove of the safety sliding contact line is less than 6mm, the requirement on the installation precision of a gantry crane cart track and the sliding contact line is very high, the whole horizontal (up-down) and left-right deviation can not exceed 50mm, however, the asynchronous deformation caused by objective factors such as installation construction error, poor daily maintenance and adjustment, heat expansion and cold contraction of a steel rail and the sliding contact line is inevitable as the gantry crane cart track and the power supply sliding contact line are as long as 780m, the vertical distance between the steel rail surface and the sliding contact line, left-right deviation and the like are large, the actual measurement is larger than 80mm, and the deviation rectifying capability of the existing device can not adapt to the actual working condition; (2) because the bridging distance of the double-arm electricity taking device adopted by each phase power supply is large, and the distance between the two sliding knives is 500mm, when a large wheel of a gantry crane passes through a steel rail joint, the deviation of settlement values at two ends is large, and when a steel rail or a sliding contact line is locally sunk or is in a section with large left-right deviation, the sliding knives at the front and rear positions are easy to be separated from the sliding groove due to overlarge vertical and left-right swinging amplitude, so that the sliding contact line is damaged; (3) each group of sliding contact lines which are originally designed and installed is provided with four splicing joints and 4 sliding knives which are all arranged on the same horizontal section, so that structural defects such as impact and vibration exist simultaneously when a gantry crane passes through the sliding contact lines, and the gantry crane sliding knives are frequently separated or clamped and damaged; (4) the spring force that the sliding knife received is difficult to carry out the adaptability adjustment, and if the tensile force is too big can push up the bending even top split wiping line, the not enough of tensile force can cause electric arc burn, electric default phase damage because of contact failure, because the actual tensile force variation of sliding knife at each point is great in the whole course operation in-process, easily causes whole wiping line unbalanced wear, has shortened wiping line life-span.
