Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of water structures cleaning, and particularly relates to a garbage transfer vehicle operating with a cleaning machine on a same track. BACKGROUND

[0002] A cleaning machine is generally arranged at the water inlet of a water structure, especially for a hydropower station with a large number of water inlets, the length of the water inlet structure can be more than 100 meters. The cleaning operation of the cleaning machine generally includes the following steps: first, the lifting mechanism is controlled to carry the cleaning grab bucket to run along the trash rack to grab the garbage underwater. After being lifted out of the dam surface, the cleaning machine performs the garbage unloading operation. There are various ways for the cleaning machine to unload the garbage. Most of the cleaning machines need to run to the designated unloading point at the end of the track, and then dump the garbage to the ground or a vehicle. There are also other transfer ways, such as using a flip plate to dump the garbage outside the track, or using a conveyor belt to transport the garbage to a suitable position.

[0003] The garbage transfer way of the existing cleaning machine has the following problems. For a cleaning machine with a long running distance, the general unloading point is generally arranged at one end of the track. The running speed of the cleaning machine under light load conditions is generally 10-20 m / min, and the fastest is 20 m / min. The cleaning machine travels more than 10 minutes in the maximum interval, and spends half of the time in the cleaning process to unload the garbage at the unloading point.

[0004] During the process of the cleaning machine carrying the cleaning grab bucket to the unloading point, the garbage in the grab bucket and the water will be scattered and pollute the dam surface environment or fall back into the water surface of the water inlet due to the semi-open structure of the grab bucket. The scattered garbage is relatively dispersed and is more troublesome to clean up again.

[0005] In most hydropower stations, the garbage grabbed by the cleaning machine is temporarily stored in a designated platform or container on the dam surface, and then transported away by a transport vehicle. This garbage temporary storage method generally requires two times of loading, increases the workload, and the sanitary environment of the temporary storage platform is not good. The temporary storage platform also needs to be cleaned up after completing the cleaning work, which consumes a lot of manpower.

[0006] Although some cleaning machines also use the way of directly unloading the garbage to the transport vehicle. However, this way is generally only suitable for large cleaning machines, or only small vehicles can be used, and a vehicle needs to follow and cooperate with the action of the cleaning machine at all times. The use of a conveyor belt to transport garbage requires a conveyor belt to be arranged on the water structure in a long range, which is not available on most water structures, and the conveyor belt is generally small and has poor effect.

[0007] In summary, the current garbage storage and transportation way of the cleaning machine is not only low in efficiency, but also the open storage and transportation way is not conducive to maintaining a clean and sanitary dam surface environment. SUMMARY

The top surface of the frame 11 is provided with the lifting mechanism 3, the push plate mechanism 22, the box door oil cylinder 231, the locking telescopic oil cylinder 154 and the telescopic wheel oil cylinder 134 on one side of the garbage compression box 2 to provide hydraulic power for the hydraulic system 6.

[0045] The working process of the present application is as follows: when the transfer trolley runs on the track 81 of the cleaning machine, the transfer trolley runs under the support of the driving mechanism 12 and the telescopic wheel mechanism 13. The power is provided by the motor 123 with a brake function to realize the back-and-forth running of the transfer trolley.

[0046] When the transfer trolley needs to run under the cleaning machine to receive the dirt, the cleaning machine should be in a parking state. The transfer trolley slowly approaches the cleaning machine 8. The suspension wheel 141 first contacts the end slope 72 of the suspension track 7 to start climbing, at this time the telescopic wheel 131 leaves the cleaning machine track 81. The driving mechanism 12 continues to drive the transfer trolley to complete the climbing, the suspension wheel 141 enters the first groove 73, the first sensor outside the first groove 73 senses the suspension wheel 141, and the operator can operate the transfer trolley to stop after seeing the in-place signal on the operation table 4. Then the telescopic wheel mechanism 13 is operated to retract, and after the telescopic wheel mechanism 13 completes the retraction, it will not interfere with the lower cross beam 83 of the cleaning machine, and the transfer trolley has been converted to rely on the driving mechanism 12 and the suspension wheel mechanism 14 to support the running. Continue to operate the driving mechanism 12 to drive the transfer trolley to run to the other end of the cleaning machine, until the suspension wheel 141 enters the second groove 74, the second position sensor senses the suspension wheel 141, and the operator can operate the driving mechanism 12 to stop after seeing the in-place signal of entering the second groove 74 on the operation table 4. Then release the brake function of the motor 123 with a brake function, so that the transfer trolley is in a free state in the running direction. The operator operates the locking telescopic oil cylinder 154 to extend the telescopic wedge 151 on both sides of the trolley 1 until it is clamped into the locking groove 152, at this time the locking between the transfer trolley and the cleaning machine is completed, and the cleaning machine 8 can carry the transfer trolley to run together.

[0047] The trash grab 82 of the trash cleaner can unload the grabbed trash from the upper opening of the trash bin 21 into the trash bin 21. Then the push plate mechanism 22 is operated to compress the trash to the end of the bin door 23 of the trash bin 21, and the push plate mechanism is withdrawn to wait for the next compression. After receiving the trash unloaded by the trash grab 82 for several times, the transfer trolley can start to separate from the trash cleaner.

[0048] When the transfer trolley needs to separate from the trash cleaner, the trash cleaner should be kept in a parked state. First, the locking telescopic oil cylinder 154 is operated to withdraw the telescopic wedge 151 from the locking groove 152 to the retracted position, and then the brake function of the motor 123 is restored. The drive mechanism 12 is operated to drive the trolley 1 to run away from the trash cleaner 8 until the suspension wheel 141 runs into the first groove 73. After the first sensor outside the first groove 73 senses the suspension wheel 141, the operator operates the telescopic wheel oil cylinder 134 to extend the telescopic wheel 133, and continues to operate the drive mechanism 12 to drive the trolley to run down the slope 72, and the telescopic wheel 133 contacts the trash cleaner track 81. The separation of the transfer trolley and the trash cleaner is completed.
