Abstract
The invention relates to a load lift and running torsional pendulum preventing device of an electromagnetic bridge crane, comprising a fixed mount, a sliding mount and a suspended beam, wherein the lower end of the fixed mount is provided with a lower guide pulley; the upper part of the sliding mount is provided with an upper guide pulley; the upper guide pulley of the sliding mount is in contact with the inner side surface in the fixed mount; the lower guide pulley of the fixed mount is in contact with the outer side surface of the sliding mount; the bottom of the sliding mount is provided with a disk; a pivoting support is fixed at the bottom of the disk by a bolt; and a drive device on the disk is characterized in that a motor and a speed reducer are meshed with the pivoting support by a gear, and the suspended beam is connected with the disk by supporting rollers and pinch rollers. The fixed mount is applied to a fixed track of the sliding mount, and the sliding mount makes reciprocating sliding in the fixed mount to form a rigid body with a cancelled structure, thereby overcoming the torsional pendulum generated load lift; when load torsional pendulum is generated, the supporting roller and the pinch roller are in contact at both a deviation end and the other end, which enable the load to be in a balancing state, thereby ensuring the stability of the load and a running lift mechanism.
Description
Technical field
The present invention relates to a kind of anti-matching component that rocks electromagnetic bridge crane, particularly a kind of electromagnetic bridge crane is prevented load lift, running torsional pendulum device.
Background technology
The electromagnetic bridge crane of present domestic hoisting crane industry manufacturing does not all have anti-lifting, running torsional pendulum device.Usually load lift mechanism is connected with suspension hook by steel rope, is directly hung on drop in beam by suspension hook again, hangs electromagnet below the drop in beam.Steel rope belongs to a kind of flexible body, when electromagnet load and unloading, has bigger impulsive force, makes load occur seriously rocking, and weight is difficult to the location and places.Simultaneously, electromagnet is when absorption load, be difficult to make load center to overlap with the drop in beam center, the skew end can make drop in beam moment increase, lifting of load deflection and suspension hook tiltedly draw, and cause the pivoting support profile of tooth to be damaged, even the tie bolt of pivoting support are cut fracture, influence the in-use performance of drop in beam and hoisting crane, even fatal accident occurs.
Summary of the invention
Purpose of the present invention just provides the anti-load lift of a kind of electromagnetic bridge crane, running torsional pendulum device, and this device can make load lift and operation held stationary, and is safe in utilization.
Electromagnetic bridge crane of the present invention is prevented load lift, the running torsional pendulum device, comprise fixed mount, sliding rack, lifting rope, suspension hook, drop in beam, wherein: the I-beam section of fixed mount upper end links to each other with the crane carriage base cross members, track adjusting wheel is down installed for four jiaos in the lower end of fixed mount, sliding rack is arranged in the fixed mount, track adjusting wheel is installed for four jiaos in the top of sliding rack, the last track adjusting wheel of sliding rack contacts with the fixed mount medial surface, the following track adjusting wheel of fixed mount contacts with the sliding rack lateral surface, form each four supporting-point up and down, sliding rack passes through lifting rope, suspension hook links to each other with crane carriage, the bottom of sliding rack is provided with disk, pivoting support is by being bolted to disk bottom, actuating device on the disk is by motor, retarder is by gear and pivoting support engagement, drop in beam passes through bogie wheel, pinch roller links to each other with disk, and pinch roller contacts with disk upper surface, and bogie wheel contacts with lower disk surface.
Electromagnetic bridge crane of the present invention prevents that load lift, running torsional pendulum device can unite use with the hoisting crane miscellaneous part, the fixed mount of crane carriage bottom is used for the trapped orbit of sliding rack, sliding rack reciprocatingly slides with crane lifting in fixed mount, form the rigid body of cancelled structure, what occur when overcoming load lift rocks.When electromagnet absorption load, bogie wheel and pinch roller guiding are arranged on the rotating disk of sliding rack bottom all the time, when appearance load is rocked, except that the skew end has bogie wheel and pinch roller contacts, the other end has bogie wheel to contact with pinch roller equally, make load be in state of equilibrium, thereby guarantee the steady of load, operation lifting mechanism.
