[0002] With the development of society, the current gantry cranes are getting bigger and bigger, and the span of gantry cranes is getting longer and longer. Therefore, when the gantry cranes are moving, the gantry cranes tend to move forward due to the inconsistent moving speeds on the left and right sides. , while the other side of the gantry crane is relatively lagging behind, causing the gantry crane to gnaw on the rail

Embodiment Construction
[0016] refer to figure 1 As shown in Fig. 4, a synchronous deviation correction device for a gantry crane includes a synchronous deviation correction device 1 fixedly installed at the casters 2 on the left and right sides of the gantry crane respectively. The driven wheel 10 that rotates synchronously with the caster 2 is connected with an encoder 11 for recording the number of rotations of the driven wheel 10, and the encoder 11 is connected with a control center. The side casters 2 are respectively equipped with a synchronous deviation correction device 1, and the synchronous deviation correction device 1 is provided with a driven wheel 10 which is in contact with the caster wheel 2 and can rotate synchronously with the caster wheel 2. The driven wheel 10 is connected with a When the gantry crane is moving, the casters 2 on the left and right sides of the gantry crane drive the driven wheel 10 connected to it to rotate, and then the encoder 11 transmits the number of turns o...

The invention discloses a synchronous deviation correcting device of a portal crane. The synchronous deviation correcting device of the portal crane comprises synchronous deviation correcting instruments respectively mounted at castors which are mounted on the left and right sides of the portal crane, wherein each synchronous deviation correcting instrument comprises a driven wheel which is in contact with the corresponding castor of the portal crane and can synchronously rotate with the castor; the driven wheels are connected with encoders for recording the rotation turns of the driven wheels; the encoders are connected with a control center. With the adoption of the structure, the control center monitors the rotation turns of the driven wheels mounted on the left side and the right side of the portal crane in real time; if the difference of the rotation turns of the two driven wheels reaches a set value, the control center sends signals to control the castor on one side with the driven wheel with more rotation turns to decelerate, so that the castor on the other side of the portal crane can catch up to the caster on one side, the left side and the right side of the portal crane can move forward as synchronous as possible, and large-angle deviation is avoided.
Description
technical field [0001] The invention relates to a synchronization mechanism, in particular to a synchronization correction device for a gantry crane. Background technique [0002] With the development of society, the current gantry cranes are getting bigger and bigger, and the span of gantry cranes is getting longer and longer. Therefore, when the gantry cranes are moving, the gantry cranes tend to move forward due to the inconsistent moving speeds on the left and right sides. , while the other side of the gantry crane is relatively lagging behind, causing the gantry crane to gnaw on the rail. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a synchronous rectifying device which has a simple structure and can adjust the moving speed of the left and right sides of the gantry crane. [0004] The technical scheme that the present invention adopts for solving its technical problem is: [0005] A synchr...
