The present embodiment adjusts the two ends of the truss trolley suction dredger by increasing the truss trolley suction dredger automatic deviation rectifying device, reduces the equipment rail biting, derailment and other failures, and thus improves the stability of the truss trolley suction dredger.

[0023] Specifically, the truss trolley suction dredger automatic deviation rectifying device of the present embodiment is used in a sedimentation tank and a truss trolley suction dredger working bridge. The truss trolley suction dredger working bridge is movably arranged above the sedimentation tank, and the truss trolley suction dredger working bridge is provided with independently controlled driving devices at both ends. Referring to Figs. 1 to 4 , the sedimentation tank can be long strip-shaped, the truss trolley suction dredger working bridge is arranged on the sedimentation tank and can move along the length direction of the sedimentation tank, for example, move along the track. The truss trolley suction dredger working bridge can be provided with a suction dredging mechanism at the upper end of the truss trolley suction dredger working bridge, and a mud scraping plate for scraping mud at the lower end of the truss trolley suction dredger working bridge. The driving devices on both sides of the truss trolley suction dredger working bridge are independently controlled, that is, the two driving devices can operate at different speeds and / or frequencies.

[0024] Among them, the truss trolley suction dredger automatic deviation rectifying device mainly includes a fixed detection seat 1, a running detection device 2 and an electrical control system 3.

[0025] The fixed detection seat 1 comprises at least one set of fixed detection seats 1, each set of fixed detection seats 1 comprises two fixed detection seats 1 respectively arranged on both sides of the length direction of the sedimentation tank. The fixed detection seat 1 can be two sets, three sets, four sets, five sets, etc., and a plurality of fixed detection seats 1 can be arranged according to the length of the sedimentation tank, and the displacement of the working bridge of the dredging machine is detected step by step during the operation of the equipment. The two fixed detection seats 1 in each set of fixed detection seats 1 are aligned in the width direction perpendicular to the length direction of the sedimentation tank.

[0026] The running detection device 2 comprises two running detection devices 2 respectively arranged at both ends of the working bridge of the dredging machine, and the running detection device 2 is used to contact the fixed detection seat 1. The running detection device 2 can record the time when the contact occurs or send a contact signal to the electrical control system 3, and the electrical control system 3 records the time when the contact signal is sent. The running detection device 2 is arranged in alignment at both ends of the working bridge of the dredging machine, and when the working bridge of the dredging machine runs synchronously at both ends, the two ends are aligned in the width direction of the sedimentation tank. The two running detection devices 2 are respectively used to detect the contact with the two fixed detection seats 1, so as to obtain the contact time of the two fixed detection seats 1, and then judge the synchronization of the running of the two driving devices. When the error of one end is detected to exceed the set value, the running speed of any one end driving is adjusted, so as to achieve the function of correcting deviation.

[0027] The electrical control system 3 is arranged on the working bridge of the dredging machine, and the electrical control system 3 is connected with the running detection device 2 and the driving device. The electrical control system 3 can adopt PLC and frequency conversion control, for example, and the running speed of the driving device on both sides is adjusted by frequency conversion control. During the operation process, the time difference of asynchronization of the driving devices on both sides can be detected in real time, and the running speed of the driving devices on both sides is adjusted according to the detected time difference, so as to realize the function of automatic deviation correction.

[0028] In some examples, when the automatic deviation correction device of the dredging machine of the present embodiment is initially operated, the running rates of the driving systems on both sides are equal and are 50Hz. When the driving device is running as shown in Fig. 2 , the driving device does not deviate, and the time difference of the two sides is zero or less than the set value, so no correction is performed. When the driving device continues to run as shown in Fig. 3 , the left end detects the fixed detection seat on the side of the pool in advance, and the electrical control system 3 such as PLC is controlled to reduce the running frequency of the left end driving system, so that the left end driving system runs at a reduced speed, thereby avoiding the problems of biting rail and derailing. When the driving device runs as shown in Fig. 4 , the right end driving detects the fixed seat on the side in advance, and the control system reduces the running frequency of the right end driving system to reduce the running speed of the right end, thereby achieving the function of automatic deviation correction.

[0029] In some examples, the fixed detection seat 1 comprises a fixed rod 12 and a collision rod 13 connected to the fixed rod 12, the fixed rod 12 is connected to the sedimentation tank, and the collision rod 13 extends to the sedimentation tank, so as to realize the fixed installation of the fixed detection seat 1 in the sedimentation tank and the cooperation with the operation detection device 2.

[0030] In some examples, the operation detection device 2 comprises a mounting seat 21, a swing rod 22 and a detection switch 23, the first end of the mounting seat 21 is used to be connected with the end of the working bridge of the floating crane suction dredger, so as to realize the synchronous movement of the operation detection device 2 with the working bridge of the floating crane suction dredger. The swing rod 22 is rotatably connected to the second end of the mounting seat 21, the first end of the swing rod 22 is used to be in contact with the collision rod 13, and the detection switch 23 is connected to the mounting seat 21 and is used to detect whether the second end of the swing rod 22 is deviated. When the first end of the swing rod 22 is in contact with the collision rod 13, the swing rod 22 rotates, so that the second end of the swing rod 22 is deviated, and the detection switch 23 can judge whether the operation detection device 2 reaches the position where the fixed detection seat 1 is located by detecting whether the second end of the swing rod 22 is deviated.

[0031] In some examples, the collision rod 13 is bent relative to the fixed rod 12, so as to be able to extend into the sedimentation tank.

[0032] In some examples, the first end of the mounting seat 21 is a horizontal section, the second end of the mounting seat 21 is a bent section which is bent downward relative to the horizontal section and is connected to the horizontal section, the horizontal section is used to be connected with the end of the working bridge of the floating crane suction dredger, so as to realize the fixation of the operation detection device 2. The swing rod 22 is pivotally arranged on the bent section, and the swing rod 22 can keep drooping under the action of gravity.

[0033] In some examples, the first end of the swing rod 22 is below the pivot center of the swing rod 22, the second end of the swing rod 22 is above the pivot center of the swing rod 22, the detection switch 23 is arranged below the horizontal section, and the detection switch 23 is towards the upper side of the pivot center of the swing rod 22, so as to avoid the damage of the detection switch 23 caused by being touched by the fixed detection seat 1.

[0034] In some examples, the fixed detection seat 1 is multiple groups, and the multiple groups of fixed detection seats 1 are uniformly arranged on the two side ends of the sedimentation tank along the length direction of the sedimentation tank, so as to improve the detection frequency of the synchronism in the movement process of the working bridge of the floating crane suction dredger, and help to keep the whole process synchronism.

[0035] Finally, it should be emphasized that the above description is only the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
